Masonry line block and corner pole

A masonry line block is adapted for use in combination with a vertical corner pole during construction of a structure. The structure has an exterior surface and at least one surface projecting from the exterior surface. The line block engages the corner pole at one end of the structure and cooperates with a line holder located at an opposite end of the structure to carry a tensioned guide line therebetween. The guide line indicates proper placement and alignment of building units used to form the structure. The line block includes a mounting member having first and second, opposing pole-engaging shoulders. The shoulders are adapted for selectively engaging the corner pole to hold the line block in one of first and second alignment positions relative to the structure. An alignment member is formed with the mounting member and extends perpendicularly outwardly from the pole-engaging shoulders. The alignment member has first and second opposing sides and defines a thickness corresponding generally to a distance between the outer surface of the structure and the projecting surface of the structure. In the first alignment position of the line block, the alignment member is adapted for locating the guide line relative to the structure to indicate proper placement and alignment of building units used to form the exterior surface of the structure. In the second alignment position of the line block, the alignment member is adapted for locating the guide line relative to the structure to indicate proper placement and alignment of building units used to form the at least one projecting surface of the structure.

TECHNICAL FIELD AND BACKGROUND OF INVENTION

This invention relates to a masonry line block and corner pole used during formation of a structure, such as a residential home, commercial building, privacy wall, and the like. The line block engages the corner pole at one end of the structure and cooperates with a line holder located at an opposite end of the structure to carry a tensioned guide line. The guide line indicates proper placement and alignment of building units, such as bricks or concrete blocks, used to form the structure. The invention is especially applicable for forming decorative quoins common in many residential homes. The decorative quoin, are formed at the junction of intersecting brick walls, and are defined by overlying bricks arranged to project slightly outwardly from respective exterior surfaces of the brick walls. The decorative quoins are generally spaced-apart along one or more corners of the brick structure.

Present methods for forming decorative quoins are tedious and time consuming. The problems result largely from the design of the cooperating line blocks used to carry the tensioned guide line. Prior art line blocks generally have a single mounting shoulder which frictionally engages the corner pole to hold the line block to the corner pole, and a body portion extending perpendicularly outwardly from the mounting shoulder. The line blocks are simultaneously moved vertically up the length of the corner pole as successive courses of brick are laid by the brick mason. For structures with decorative quoins, the corner poles are generally moved and the entire quoin constructed before relocating the corner poles and completing the remainder of the structure. This technique is inefficient and relatively labor intensive Moreover, because the guide line is tensioned between the corner poles, it is not uncommon for a line block to inadvertently slip off a corner pole and strike a nearby worker causing injury.

DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, a masonry line block according to the present invention is illustrated in FIG. 1 and shown generally at reference numeral 10 . The line block 10 is generally used in pairs in combination with a masonry corner pole 11 , such as shown in FIGS. 6-10 , to construct a brick structure S including decorative quoins Q . The decorative quoins Q are formed at the junction of intersecting brick walls W , and are defined by overlying bricks arranged to project slightly outwardly from respective exterior surfaces of the brick walls W . The decorative quoins Q are vertically spaced-apart along one or more corners of the brick structure S . The line blocks 10 and 10 cooperate with the corner pole 11 and respective line holders (not shown) located at opposite ends of each brick wall W to carry respective tensioned guide lines 12 and 12 used to maintain proper placement and alignment of the brick courses. The line holders may be additional corner poles or other structure sufficient for holding the guide lines 12 and 12 in a tensioned condition.

Referring to FIGS. 1-5 , the line block 10 is generally T-shaped and includes an integrally formed mounting member 14 and alignment member 15 . The mounting member 14 has opposing, pole-engaging shoulders 16 and 17 with respective anchors 18 and 19 adapted for securing the line block 10 to the corner pole 11 , as described further below. The alignment member 15 extends perpendicularly outward from the mounting member 14 between the opposing shoulders 16 and 17 , and has first and second opposing sides 21 and 22 . Arcuate openings 24 and 25 are preferably formed at a junction of the mounting member 14 and respective opposing sides 21 and 22 of the alignment member 15 to accommodate excess guide line 12 wrapped around the line block 10 to attach the guide line 12 to the line block 10 . Shallow grooves 26 and 27 are formed in the sides 21 and 22 of the alignment member 15 to selectively receive and secure the position of the guide line 12 as it extends outwardly from the line block 10 towards the distant line holder located at the opposite end of the brick wall W . Preferably, the mounting member 14 includes corresponding slots 28 and 29 formed in registration with the grooves 26 and 27 to receive an end of the guide line 12 attached to the line block 10 . As best shown in FIG. 2 , the slots 28 and 29 taper outwardly from the back end of the mounting member 14 and meet the grooves 26 and 27 extending to the front end of the alignment member 15 .

According to one preferred embodiment, the distance a , shown in FIG. 2 , from one side 21 of the alignment member 15 to an outside edge of the anchor 18 is approximately inches. The distance b from a front end of the groove 26 formed in one side 21 of the alignment member 15 to the opposite side 22 of the alignment member is between and 1 inches, and is preferably either , , or 1 inches depending on the desired distance between the exterior surface of the quoin Q and the exterior surface of the brick wall w . The overall length of the line block is 3 inches.

Referring now to FIGS. 6-10 , cooperating line blocks 10 and 10 are shown as used in combination with the masonry corner pole 11 to form a brick structure S having intersecting brick walls WW and decorative quoins Q formed at a corner of the structure. Like elements of the line block 10 are shown in prime notation. The corner pole 11 is vertically mounted at the corner of the brick structure S and has an elongate body portion 31 with four sides defining four equally spaced-apart longitudinal edges 32 , 33 , 34 , and 35 . First and second longitudinal anchor flanges 36 and 38 are formed at a diagonally-opposing two of the four longitudinal edges 32 - 35 . The anchor flange 36 , 38 extends into the open space formed between the inside edge of the anchor 18 , 19 and the side 21 , 22 of the alignment member 15 to secure the line block 10 to the corner pole 11 . The tensioned guide lines 12 and 12 are attached to the line blocks 10 and 10 and extend from the corner pole 11 to respective opposite ends of the brick walls W . The line blocks 10 and 10 are moved vertically up the length of the corner pole 11 to position the guide lines 12 and 12 accordingly when laying successive courses of brick.

When laying bricks to form the brick wall W of the brick structure S , the line block 10 is oriented, as shown in FIGS. 7 and 9 , such that one shoulder 16 of the mounting member 14 engages the corner pole 11 while the alignment member 15 acts to space the guide line 12 away from the corner pole 11 and closer to the brick wall W . The guide line 12 serves to indicate the proper placement of bricks as necessary to maintain precise vertical alignment of the brick wall exterior. The line block 10 remains oriented on the corner pole 11 in this alignment position and is slid upwardly along the length of the corner pole 11 until the mason is ready to form a decorative quoin Q . The longitudinal anchor flange 36 of the corner pole 11 and anchor 18 formed with the mounting member 14 cooperate to prevent the line block 10 from inadvertently flying off the corner pole 11 under the tension of the guide line 12 .

To form the quoin Q , the mason simply flips the line block 180 degrees to the alignment position shown in FIGS. 8 and 10 such that the opposite shoulder 17 of the mounting member 14 engages the corner pole 11 while the alignment member 15 positions the guide line 12 directly adjacent a side of the corner pole 11 and away from the previously formed exterior of the brick wall W . The longitudinal anchor flange 36 and anchor 19 formed with the mounting member 14 now cooperate to prevent the line block 10 from inadvertently flying off the corner pole 11 , as described above. After the first brick course of the decorative quoin Q is laid, the mason flips the line block 180 degrees back to its original alignment position on the corner pole 11 to position the guide line 12 for placement of the next course of bricks used to form the brick wall W . When the mason reaches the quoin Q , the line block 10 is again flipped 180 degrees to position the guide line 12 for laying the next course of bricks used to form the quoin Q . This process is repeated until construction of the brick structure S is completed. Preferably, the process takes place using two line blocks 10 and 10 mounted on a single corner pole 11 , as shown, such that each brick wall W and each side of the decorative quoin Q are formed at the same time. The line block 10 functions in an identical manner described above with reference to line block 10 , and is secured to the corner pole 11 by the anchor flange 38 .

The line block 10 may be constructed of any suitable material, such as wood, molded plastic, or aluminum. The line block 10 may be used in combination with the masonry corner pole 11 , described above, or in combination with any other conventional corner pole. Likewise, the masonry corner pole 11 is further applicable for use in combination with any other conventional line block.

A masonry line block and corner pole are described above. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation the invention being defined by the claims.
