Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a foldable quick-assembly steel truss floor deck. Background Technology

[0002] In the field of building construction, floor decking is a structural component that plays a key role in the construction of concrete floor slabs. It not only has to bear various loads during the construction phase, including the weight of concrete, construction personnel and equipment, but also has to provide stable support for the floor slab during the building's use. With the continuous development of the construction industry, increasingly higher requirements have been placed on the performance, installation efficiency and adaptability of floor decking.

[0003] Traditional floor decking has gradually revealed some shortcomings during actual installation.

[0004] Firstly, before installing traditional floor slabs, H-beams need to be installed on the building corbels, and then the floor slabs are installed on the H-beams. However, the installation of traditional H-beams is quite troublesome, requiring tedious welding, bolting and other processes. This not only increases the labor intensity of construction workers, but also makes it easy for the installation quality to be unstable due to human factors.

[0005] To address these issues, a foldable, quick-assembly steel truss floor deck is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 This utility model provides an embodiment of a foldable quick-assembly steel truss floor deck, including corbels 1 for supporting the overall assembly. Multiple corbels 1 are made of concrete and distributed at various support points of the building. The right surface of each corbel 1 is convex to facilitate the installation of H-beams 25. A quick-assembly assembly is provided on the upper surface of each corbel 1, including a pre-embedded plate 21. The pre-embedded plate 21 is embedded in the corbel 1 during pouring to facilitate the subsequent installation of the H-beams 25. A fixing bracket 22 is inserted into the upper surface of each corbel 1, and the upper surface of the fixing bracket 22 is threaded through and connected to a fixing device for securing the fixing bracket 22. The bolts 23 of the embedded plate 21 and the slot 201 in the middle of the upper surface of the fixing frame 22 are provided. The inner wall of the slot 201 is inserted with the column 24. The column 24 and the slot 201 fit together. When the column 24 and the slot 201 are inserted, they can provide support for the H-beam 25. Concrete can be poured at the opening above the fixing frame 22 to ensure the stability of the H-beam 25. The upper surface of the column 24 is fixedly connected to the H-beam 25. There are two sets of columns 24, which are evenly distributed at both ends of the lower surface of the H-beam 25. The upper surface of the H-beam 25 is provided with the installation component, which facilitates the installation of the floor slab body 31.

[0033] Reference Figure 1 - Figure 3The installation components include floor slab bodies 31, of which multiple floor slab bodies 31 are provided and stacked in a folded manner. When needed later, multiple floor slab bodies 31 can be assembled. Some floor slab bodies 31 are designed in a truncated shape to facilitate the installation of components such as central air conditioning units. When assembling the floor slab bodies 31, manual alignment is required, which is troublesome and the alignment quality is difficult to guarantee. The rear surface of the floor slab body 31 is rotatably connected to a rotating rod 32. There are three sets of rotating rods 32, which are equidistantly distributed in the left and right directions. The bottom end of the rear surface of the floor slab body 31 is fixedly connected to a connecting plate 33. The front and rear ends of the upper surface of the floor slab body 31 are provided with threaded grooves. The front surface of the floor slab body 31 is provided with a circular groove 301, which is engaged with the rotating rod 32. The lower surface of the floor slab body 31 is provided with a positioning groove 302, which is engaged with the connecting plate 33.

[0034] Reference Figure 1 , Figure 4 The embedded plate 21 is inserted through and fixedly connected to the upper surface of the bracket 1. The upper surface of the bracket 1 is set in a recessed shape to facilitate the installation of the fixing frame 22. The embedded plate 21 is located in the recessed area, and the bolt 23 is inserted through and threadedly connected to the upper surface of the embedded plate 21, which can firmly fix the fixing frame 22 and the embedded plate 21.

[0035] Reference Figure 1 - Figure 3 The floor slab body 31 is welded to the upper surface of the H-beam 25. The left and right ends of the lower surface of the floor slab body 31 are welded to the H-beam 25. The floor slab bodies 31 are fixed together by screws. The top end of the rear surface of the floor slab body 31 is set as a slope, and the bottom end of the front surface of the floor slab body 31 is set as a slope. The slope at the top end of the rear surface of one floor slab body 31 and the slope at the bottom end of the front surface of another floor slab body 31 fit together. At this time, the threaded grooves will be aligned, which makes it easy to install the floor slab bodies 31 together and reduces the time spent on alignment. The rotating rod 32 is inserted into the inner wall of the circular groove 301, and the connecting plate 33 is inserted into the inner wall of the positioning groove 302.

[0036] Working principle: When using this device, first insert the fixing frame 22 into the recess on the bracket 1, and then use bolts 23 to fix the fixing frame 22 and the embedded plate 21 together. After the fixing frame 22 is fixed, align and insert the columns 24 at the left and right ends below the H-beam 25 with the slots 201 on the two fixing frames 22 respectively to complete the initial fixing of the H-beam 25. Then pour concrete into the fixing frame 22. After the concrete solidifies, the fixing of the H-beam 25 will be completed, ensuring the stability of the H-beam 25 in subsequent use.

[0037] Then, one floor slab body 31 is welded to the H-beam 25, and the inclined surface of the front end of another floor slab body 31 is aligned with the inclined surface of the rear end of the first floor slab body 31. During placement, the inclined surface of the front end of the second floor slab body 31 will contact the rotating rod 32 on the first floor slab body 31, and the rotating rod 32 will roll, causing the second floor slab body 31 to move downwards until it falls to the bottom. Then, the second floor slab body 31 is moved laterally to align the circular groove 301 and the rotating rod 32. One floor slab body 31 will fall down, the rotating rod 32 will be inserted into the circular groove 301, and the connecting plate 33 will be inserted into the positioning groove 302. When the other floor slab body 31 moves back and forth, it is in contact with the surface of the rotating rod 32, and the contact area is small, so it is easier to move. When the rotating rod 32 is inserted into the circular groove 301, the threaded grooves on the floor slab body 31 will be aligned, and the floor slab bodies 31 can be installed together with screws. Even if some parts of the floor slab body 31 are cut off, they can still be installed in the same way.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
