Disclosed is a goods shelf, comprising a plurality of beams (2), a plurality of supporting parts (1) and at least one placing part (3). Each of the beams (2) is connected to the corresponding supporting part (1) via a connector, and on a side thereof has a placing surface (12) for placing the corresponding placing part (3). At least two opposing ends of the placing part (3) are provided on the placing surface (12) in the same plane of at least two corresponding beams (2). The plurality of beams (2) and the plurality of supporting parts (1) are profiles formed by extrusion and stretching of a mould.
A: A glass substrate handling apparatus comprising a support frame (1) and a substrate holding frame (2). The substrate holding frame comprises a first support part (21), a second support part (22), and a sliding part (23). The first support part (21) is provided on the second support part (22) via the sliding part (23). Also, the first support part (21) is allowed to move relative to the second support part (22) between a first position and a second position along a first direction of the support frame under an action of the sliding part (23). When the first support part (21) is located at the first position, the entire first support part (21) is projected towards the outer side of the second support part (22). When the first support part (21) is located at the second position, the entire first support part (21) is located directly above the second support part (22). The present invention has the substrate holding frame configured as a telescopic structure, when handling a glass substrate on a handling apparatus platform, the need to extend the bottom part of the handling apparatus below the handling apparatus platform is obviated, and glass substrate handling is allowed by extending the substrate holding frame to a glass substrate placement position on the handling apparatus platform.
B: A beam-column connection member (400), a building frame structure, and an installation method. The beam-column connection member (400) comprises an integrated beam-column connection member body (1), a vertical column insertion connector (2), and beam insertion connectors (3, 4); the beam insertion connector (3, 4) comprises a first support portion (22) directly supporting a lower wing plate of the horizontal beam, and a first fixing portion (5) disposed right above the first support portion (22), horizontally protruding along the side of the beam-column connection member body (1), and fixed to the web of the horizontal beam; the distance in the vertical direction between the first fixing portion (5) and the first support portion (22) is greater than the thickness of the lower wing plate of the horizontal beam, the width of the first fixing portion (5) in the vertical direction is smaller than the distance between two opposite faces of the two wing plates of the horizontal beam; and a stop portion (12) for stopping the end portion of the vertical column is further provided. An H-shaped or I-shaped horizontal beam has end portions that do not require processing, has many positions for connection and fixation, has stable and reliable connecting nodes, and has desirable strength and rigidity for connecting positions; the building frame structure can be conveniently mounted and only a few of working steps are involved.
C: Disclosed is a vehicle front floor structure, an aluminum alloy extrusion molded part and a vehicle. The vehicle front floor structure comprises a left threshold (1), a right threshold (2) and a plurality of beams (3) arranged between the left threshold (1) and the right threshold (2), wherein each of the beams (3) comprises at least two first-type beams arranged at intervals, and the at least two first-type beams are both aluminum alloy extrusion molded parts and are configured to have different cross section shapes from each other, such that the amount of deformation of the left threshold (1) and/or the right threshold (2) when a vehicle is subject to a side collision complies with set requirements; and the set requirements comprise that a set distance is maintained between the deformed left threshold (1) and/or right threshold (2) and a vehicle component mounted and suspended on at least a part of the beams.
D: Disclosed is an assembled-type cabinet comprising two upright frames (3), a top panel (1), a base panel (13), two side panels (2), a back panel (11), a folding fixing frame (10), and at least one drawer (6). The upright frames (3) each comprise two vertical posts (5) and several crossbeams (4) perpendicular to the vertical posts (5). The folding fixing frame (10) is connected to the two upright frames (3), respectively. The top panel (1) and the base panel (13) are fixed to the crossbeams (4) at the top part of two upright frames (3), respectively, and the two side panels (2) and the back panel (11) are fixed respectively between the top panel (1) and the base panel (13). Each drawer (6) is fixed to the side panels (2) by means of sliding rails. During the process of assembling either a solid wood cabinet or a chest of drawers, the assembled-type cabinet only requires a screw-driver and does not require an excessive number of other tools, meaning the cabinet can be quickly and easily assembled, achieving fast assembly results with a saving in time and labour. In addition, after assembly, the assembled-type cabinet has a relatively high structural strength and is not easy to deform, and the drawers can be conveniently pulled out or pushed in. Additionally, the inside of the drawers can form a relatively intact storage space, able to reduce the ingress of grime, meaning that items stored therein are cleaner.
