Description

Technical Field

[0001] This utility model relates to the field of floor decking, and in particular to a snap-fit ​​steel truss floor decking. Background Technology

[0002] Steel trusses are trusses made of steel. They are commonly used as the main load-bearing components in roof structures of industrial and civil buildings, crane beams, bridges, and hydraulic gates. Various towers, such as mast towers, television towers, and transmission line towers, often use spatial steel trusses composed of three-, four-, or multi-sided planar trusses. Steel truss floor decks, on the other hand, are prefabricated building components. They are made of prefabricated steel trusses and galvanized steel sheets, which are then transported to the construction site and laid to serve as the load-bearing layer and construction platform of the floor slab. Their core uses steel bars to form a triangular truss skeleton, and galvanized steel sheets enable formwork-free construction.

[0003] Existing steel truss floor decks include detachable steel truss floor decks and non-detachable steel truss floor decks. Non-detachable steel truss floor decks consist of a base slab and steel trusses. When using non-detachable steel truss floor decks, the two ends of the base slab are supported on the top of the frame beam or shear wall. Several steel truss floor decks are then spliced ​​together to form a pouring platform. Then, steel bars are used to connect several steel truss floor decks into a whole, finally forming a solid platform for pouring concrete.

[0004] The existing steel truss floor decks mentioned above are spliced ​​by contacting each other between adjacent floor slabs. However, this method is not stable enough and is prone to movement before all floor decks are spliced. It can also cause mortar leakage during concrete pouring, resulting in voids and pores in the concrete at the splice of the steel truss floor deck, which leads to a decrease in concrete strength. Therefore, we propose a snap-fit ​​steel truss floor deck. Utility Model Content

[0005] The purpose of this utility model is to provide a snap-fit ​​steel truss floor deck to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A snap-fit ​​steel truss floor deck includes a floor deck body with a steel truss assembly welded to the top surface of the floor deck body. The floor deck body is composed of a first galvanized steel plate and a second galvanized steel plate. Symmetrical upper and lower hook edges are provided on both sides of the first and second galvanized steel plates. Multiple sets of through holes are opened in the center of each upper and lower hook edge, and a pre-embedded screw is inserted through the center of each through hole. A threaded seat is threaded to the bottom of the pre-embedded screw, and a locking nut is threaded to the top of the pre-embedded screw. A pressure plate is attached to the top surface of the upper hook edge.

[0007] Furthermore, the perforations between the upper hook edge and the lower hook edge are centered and aligned vertically, and the perforations are equidistantly arranged along the central axis of the upper hook edge and the lower hook edge.

[0008] Furthermore, the threaded seat is embedded and welded to the center of the bottom surface of the lower hook edge, and the threaded seat is threadedly fixed to the bottom end of the pre-embedded screw.

[0009] Furthermore, the first galvanized steel sheet and the second galvanized steel sheet are interlocked by the upper hook edge and the lower hook edge.

[0010] Furthermore, the clamping plate is threadedly locked to the top surface of the upper hook edge by pre-embedded screws and locking nuts.

[0011] Furthermore, the steel truss assembly includes an upper spiral bar, and web bars are welded to both sides of the upper spiral bar. A lower spiral bar is welded to one side of the bottom end of the web bar, and the bottom surface of the web bar is welded to the top surface of the floor slab.

[0012] Furthermore, the steel truss assembly is arranged at equal intervals along the top surface of the floor slab, and the lower spiral steel bars are supported by the web steel bars and the upper spiral steel bars in a triangular frame manner.

[0013] The advantages of this utility model compared to the prior art are as follows: 1. This utility model can be formed by hooking and snapping together the corresponding upper and lower hook edges on both sides of the galvanized steel plate. After snapping, the clamping plate is pressed and locked to the top surface of the upper hook edge with the pre-embedded screw and locking nut, so as to achieve seamless connection and reinforcement after the upper and lower hook edges are snapped together. This improves the connection stability of the first galvanized steel plate and the second galvanized steel plate, prevents the floor deck from moving, and avoids problems such as leakage of concrete mortar and voids in the concrete at the splice due to insufficient stability, thereby improving the quality of the floor concrete. 2. This utility model uses multiple sets of pre-welded web reinforcement bars on the top surface to be fixed together with the upper and lower spiral reinforcement bars to form the internal support structure of the overall floor deck. The structural strength and stability of the overall floor deck are improved by equidistant arrangement. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0016] like Figure 1-6 The above-displayed snap-fit ​​steel truss floor deck comprises a first galvanized steel plate 101 and a second galvanized steel plate 102. The first galvanized steel plate 101 and the second galvanized steel plate 102 are each provided with a symmetrical upper hook edge 103 and a lower hook edge 104 on both sides. Both the upper hook edge 103 and the lower hook edge 104 have multiple sets of through holes 105 in the center. A pre-embedded screw 106 is inserted through the center of the through hole 105. A threaded seat 107 is threaded to the bottom end of the pre-embedded screw 106. A locking nut 108 is threaded to the top end of the pre-embedded screw 106. A pressure plate 109 is attached to the top surface of the upper hook edge 103. As shown above, when this steel truss floor deck is connected and assembled, it can be formed by hooking and snapping together the corresponding upper hook edges 103 and lower hook edges 104 of the first galvanized steel plate 101 and the second galvanized steel plate 102. The pre-embedded screw rods 106 are inserted through the corresponding holes 105 at the center of each upper hook edge 103 and lower hook edge 104 for limiting the position. After snapping, the locking nut 108 is used to press and lock the pressure plate 109 to the top surface of the upper hook edge 103, so as to achieve seamless connection and reinforcement after the upper hook edge 103 and lower hook edge 104 are snapped together. This improves the connection stability of the first galvanized steel plate 101 and the second galvanized steel plate 102, avoids problems such as leakage of concrete mortar and voids in the concrete at the splice due to insufficient stability, and improves the quality of the floor slab concrete. The threaded seat 107 at the bottom end of the pre-embedded screw 106 is embedded and welded to the center of the bottom surface of the hook side 104. During installation, the pre-embedded screw 106 can be directly inserted through the through hole 105 and locked to the threaded seat 107, thereby reducing the on-site installation process and improving efficiency.

[0017] like Figure 1-3 As shown, the steel truss assembly 2 includes an upper spiral steel bar 201, and web steel bars 202 are welded to both sides of the upper spiral steel bar 201. A lower spiral steel bar 203 is welded to one side of the bottom end of the web steel bar 202. The bottom surface of the web steel bar 202 is welded to the top surface of the floor deck 1. As shown above, the steel truss floor deck is formed by pre-welding multiple sets of web steel bars 202 on the top surface, which are fixed together with the upper spiral steel bars 201 and the lower spiral steel bars 203 to form the internal support structure of the overall floor deck. The structural strength and stability of the overall floor deck are improved by equidistant arrangement.

[0018] In summary, when using this steel truss floor deck, the construction workers first lay the first galvanized steel plate 101 and the second galvanized steel plate 102, etc., on the floor beam in sequence, connecting them to the building structure. Then, the first galvanized steel plate 101 and the second galvanized steel plate 102 are snapped together and aligned during installation through the upper hook edge 103 and the lower hook edge 104. After the snapping and alignment are completed, the pre-embedded screw rod 106 is inserted into the through hole 105 of the upper hook edge 103 and the lower hook edge 104 in sequence, and is threaded and fixed to the threaded seat 107 at the center of the bottom surface of the lower hook edge 104. Then, the clamping plate 109 is attached to the surface of the upper hook edge 103 and passes through the pre-embedded screw rod 106. The locking nut 108 is then put into the top of the pre-embedded screw rod 106 and tightened. At this time, the locking nut 108 will also simultaneously attach the clamping plate 109 to the surface of the upper hook edge 103 and lock it, maintaining the snapping and secondary reinforcement.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
