Detailed Description

The invention will be described in further detail with reference to the drawings and specific embodiments.

As shown in fig. 1 and 2: a joist bolt decorative cover comprises a cover plate 1, wherein one end of the cover plate 1 is provided with a first clamping part 11, and the other end of the cover plate 1 is provided with a folded edge 12; the joist 2 is provided with a second clamping part 3; when the first clamping portion 11 is clamped and connected with the second clamping portion 3, the folded edge 12 of the cover plate 1 is abutted against the inner wall of the joist 2, and the threaded connecting piece on the joist 2 is covered.

In the structure, the cover plate is arranged, when the cover plate is not installed, the bolt can be conveniently screwed on the open side of the joist, and after the cover plate is installed, the bolt part can be covered, so that the bolt is protected and the attractive appearance is kept; the clamping parts are respectively arranged on the cover plate and the joist, so that when the cover plate is installed, the cover plate is only required to be clamped on the second clamping part of the joist, the installation is rapid, and the time and the labor are saved; the other end of the cover plate is provided with the folded edge, so that after the cover plate is clamped and fixed, the folded edge can be abutted to the inner wall of the joist, the contact area of the folded edge and the joist is increased, the connection stability is improved, and the inner wall of the joist is not easily scratched.

In this embodiment, an opening 21 is formed in one side of the joist 2, and the cover plate 1 extends into the inner cavity of the joist 2 along the opening 21. Namely, the cross section of the joist 2 is C-shaped, one side is open, and the other positions are closed. Through setting up uncovered 21, be convenient for twist the bolt, after the bolt installation, apron 1 only need cover in bolt department can, need not seal uncovered 21 is whole, labour saving and time saving.

In this embodiment, the top of the joist 2 is connected to the floor 5 by bolts 4. The floor slab 5 comprises a sandwich board 51 and a functional layer, wherein the functional layer comprises a heat-insulating layer 52 and a fire-proof layer 53; the insulating layer 52 is provided between the sandwich panel 51 and the fire-proof layer 53. The functional layers are arranged in a segmented mode, a connecting piece 54 is arranged between the functional layers of the adjacent segments, one end of each connecting piece 54 is welded with the sandwich plate 51, and the other end of each connecting piece 54 is connected with the joist 2 through a bolt 4. Wherein, the connecting piece 54 is provided with a threaded hole at the connecting position with the joist 2, the top surface of the joist 2 is provided with a threaded hole, and the bolt 4 enters from the open side and passes through the joist 2 to be fixed with the connecting piece 54. Or the connecting piece is prefabricated with a nut at the connecting position with the joist, the top surface of the joist is provided with a through hole, and the bolt penetrates through the through hole and is fixedly connected with the prefabricated nut. After the bolts are installed, the cover plate is covered. In addition, the upper end of the joist 2 is glued and fixed with the fireproof layer 53.

It can be understood that if the bolts are arranged at other positions of the joist, the cover plate can be arranged at the position with the bolts, for example, when the rear end surface of the joist is connected with the long beam, the bolts need to be screwed on the rear end surface for fixing, the cover plate is also arranged at the rear end surface, the clamping piece is arranged at the open side of the rear end surface for clamping and fixing, and the bottom surface of the cover plate directly contacts with the bottom surface of the inner cavity of the joist.
