Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority of Korean Patent Application No. 10-2013-0017018, filed on Feb. 18, 2013, which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     1. Field 
     The present invention relates to a dome cover supporter, and more particularly, to a dome cover supporter capable of improving productivity and durability of a product and extending a life span thereof by preventing the pressing plate of roof panel from protruding upwardly by supporting a dome cover used in a storage tank, achieving resistance against a load by decreasing surface roughness, and extending a life span by preventing gaskets from being exposed to ultraviolet rays. 
     2. Description of Background Art 
     A dome cover is used for covering a storage tank storing a product, such as crude oil or oil, or a storage tank having sealing property and chemical resistance. In order to install the dome cover on an upper surface of the storage tank, a dome cover supporter capable of supporting the dome cover in a vertical direction is required. 
       FIG. 1  is a cross-sectional view illustrating a coupling state of a dome cover supporter  10  in the related art. 
     As illustrated, in the dome cover supporter  10  in the related art, a supporter main body  11  and a pressing plate  17  are vertically positioned, and end portions of roof panels (A) are inserted there between. 
     In this case, an upper surface of an oblique bar  13  supports a lower end surface of the roof panel A to stably support the roof panel A by using a lever principle. 
     However, in the dome cover supporter  10  in the related art, when a worker inserts a screw  15  in order to couple the supporter main body  11  and the pressing plate  17 , the worker needs to ascend on the roof panel A for in order to perform the task. 
     In this case, when a load P corresponding to weight of the worker is applied to the roof panel A, is contact area between the oblique bar  13  and the roof panel A is narrow, such that there is a problem in that the roof panel A is bent as indicated by a dotted line. 
     When the bent state is maintained for a long time, there is a problem in that a gap is generated between the pressing plate  17  and the roof panel A because bending distortion is generated in the roof panel A itself, corrosion is generated because rainwater is permeated into the generated gap, and durability of the roof panel A itself deteriorates. 
     When the load P is applied, the oblique bar  13  is in first contact with the root panel A, so that a phenomenon in which stress is concentrated to a contact region, thereby causing a vulnerable structure in which a crack is generated inside the oblique bar  13  according to a case.

     DETAILED DESCRIPTION FOR IMPLEMENTING THE INVENTION 
     Hereinafter, configurations of the present exemplary embodiment will be described in detail with reference to the accompanying drawings. 
     A detailed explanation of known related functions and constitutions may be omitted to avoid unnecessarily obscuring the subject matter of the present invention. 
       FIG. 3  is an exploded perspective view illustrating a construction of a dome cover supporter according to the present invention,  FIG. 4  is a perspective view illustrating a construction of the dome cover supporter according to the present invention, and  FIG. 5  is a cross-sectional view of the dome cover supporter according to the present invention. 
     As illustrated, the dome cover supporter according to the present invention includes a supporter  100  including supporter main body  110  formed in a vertical direction, a base  130  formed in a lower portion of the supporter main body  110  to support the supporter main body  110  against the ground, and horizontal extending pieces  150  bent in an upper portion of the supporter main body  110  to be extended, and a fixing member  300  fastened to an upper portion of the supporter to maintain a seal by fixing and pressing roof panels A. 
     The supporter main body  110  has an shape of an entire cross-section so as to have rigidity against the vertical load. 
     The base  130  is integrally formed with the lower portion of the supporter main body  110  to support the supporter main body  110  from the ground, so that the dome cover may be stably fixedly coupled to the upper portion of the supporter main body  110 . 
     The horizontal extending piece  150  is integrally formed with the upper portion of the supporter main body  110 , and is bent at 45 degrees to be extended, so that the fixing member  300  may be seated therein without protruding. 
     That is, the horizontal extending piece  150  is bent at 45 degrees to be extended so that an accommodation portion  151  is formed so as for the fixing member  300  to be seated therein without protruding. Accordingly, the roof panels A are bent like a shape of the accommodation portion  151  and seated in the accommodation portion  151 , gaskets  310  for maintaining a seal are seated on the roof panels A, and then the gaskets  310  are fastened to the supporter main body  110  with bolts  350  so that the bolts  350  pass through the pressing plate  330 , and thus the roof panels A are fastened to the upper portion of the supporter main body  110 . 
     In this case, as illustrated in  FIG. 6 , the supporter main body  110  may be formed so that two support pillars correspond to each other while having an entire cross section shaped, like “H” to have strength against a vertical load and stress for an axis-directional distortion load. 
     The fixing member  300  is fastened to the upper portion of the supporter main body  110  to fixedly fasten the roof panels A, and includes the gaskets  310  seated on the end portions and the upper portions of the roof panel A so as to prevent snow or rainwater from being permeated, and the pressing plate  330  formed on the upper portions of the gaskets  310 , to fasten the pressing plate  330  to the supporter main body  110  with the bolts  350 . Accordingly, the fixing member  300  fixes the roof panels A, and simultaneously presses the gaskets  310  to maintain a seal. 
     A process of installing the dome cover by using the dome cover supporter  110  according to the present invention including the aforementioned configuration will be described with reference to  FIGS. 3 and 4 . 
     First, the supporter main body  110  is erected in a vertical direction, and the base  130  is coupled to the ground or the fixing member (not illustrated) to fix a position thereof. 
     In this case, a plurality of supporter main bodies  110  is installed in a radial direction, and front ends of the respective supporter main bodies  110  meet at one point. 
     Then, the roof panels A are disposed on the horizontal extending piece  150 , and the gaskets  310  and the pressing plate  330  are positioned. 
     Then, the worker ascends to the upper surface of the roof panel A and couples the bolts  350  to screw insertion holes  111  by passing through the pressing plate  330 . 
     According to the present invention, like  FIG. 6  when the supporter main body is provided so that the two support pillars correspond to each other, to support the dome cover, the present invention has rigidity against a vertical load and stress against an axis-directional distortion load, also another embodiment of the present invention has further improvement of stably supporting the roof panel for a long time. 
     The present invention prevents the pressing plate roof panel from protruding upwardly, so that a step of removing a rib of an upper portion of a strut assembled with a gusset is omitted, thereby allowing a rapid production. 
     The present invention may improve durability of a product and extend a life span thereof by preventing the pressing plate of roof panel from protruding upwardly, achieves resistance against a wind load by decreasing surface roughness, and may extend a life span by preventing the gaskets from being exposed to ultraviolet rays. 
     The aforementioned present invention is not limited by the aforementioned exemplary embodiments and the accompanying drawings, and it will be apparent to a person with ordinary skill in the art to which the present invention pertains that the present invention may be variously substituted, modified, and changed within a scope without being departed from the technical spirit of the present invention.
