Description

Technical Field

[0001] The utility model belongs to the technical field of floor decking, and in particular relates to a strong steel truss decking system. Background Art

[0002] The reinforced steel truss deck system, also known as the steel truss floor deck, is a commonly used structural form in steel structures. Its mechanical properties are essentially the same as those of traditional cast-in-place floor slabs, making it widely used in various building construction. A steel truss floor deck is a composite formwork constructed by processing steel bars into steel trusses and welding these trusses to galvanized corrugated steel sheets. The steel truss floor deck consists of steel trusses and a steel truss floor deck base formwork, which are secured together using spot welding. During construction, the steel truss floor deck is transported to the construction site and directly laid onto the beams. The base forms of the individual steel truss floor decks are then connected, and after simple reinforcement work, concrete can be poured. Its formwork function reduces on-site formwork erection and disassembly, significantly improving floor construction efficiency.

[0003] When existing steel truss floor decks are in use, the web reinforcement is connected to the galvanized steel plates by welding. Because welding is a rigid connection, it is easy for the welds to break due to the excessive weight of the concrete when pouring concrete. At the same time, the joints of the galvanized steel plates need to be fixed with bolts and nuts, which is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0004] The utility model provides a reinforced steel truss deck system, which aims to solve the problem that in the existing steel truss floor deck, the web steel bars are connected to the galvanized steel plates by welding when in use. Since welding is a rigid connection, it is easy for the welds to break when pouring concrete due to the excessive weight of the concrete. At the same time, the joints of the galvanized steel plates need to be fixed with bolts and nuts, which is cumbersome, time-consuming and labor-intensive.

[0005] An embodiment of the present invention provides a reinforced steel truss deck system, comprising a base plate, a steel bar assembly being provided on the base plate, and connecting portions being provided on both sides of the base plate.

[0006] Furthermore, the upper surface of the bottom plate is provided with a placement groove, and the placement groove includes placement groove 1 and placement groove 2, and the upper ends of placement groove 1 and placement groove 2 are convex edges 1 and convex edges 2 extending from both sides of the bottom plate to the middle.

[0007] By adopting the above technical solution, the lower chord steel bars and part of the web steel bars can be placed in the placement groove, so that the lower chord steel bars and part of the web steel bars do not need to be fixed to the base plate by rigid welding. The blocking of the convex edge 1 and the convex edge 2 can give the lower chord steel bars and part of the web steel bars a certain amount of space for movement.

[0008] Further, the steel bar assembly includes two lower chord steel bars respectively arranged in the first placement groove and the second placement groove. Web steel bars are respectively welded on the two sides of the lower chord steel bars. The two web steel bars are in a wavy shape. The web steel bars are divided into a wave crest section and a wave trough section. An upper chord steel bar is welded between the wave crest sections of the two web steel bars.

[0009] By adopting the above technical solution, the two lower chord steel bars, one upper chord steel bar and the web steel bars can form a triangular shape with the bottom plate, having a certain stability.

The lower wave trough section is located at the lower end of the lower chord steel bar. The upper wave trough section is located at the upper end of the lower chord steel bar. The lower chord steel bar is fixedly welded in the middle of the lower wave trough section and the upper wave trough section.

[0011] By adopting the above technical solution, the lower wave trough section and the upper wave trough section firmly weld the lower chord steel bar in the middle, changing the single-sided welding of the lower chord steel bar to double-sided welding, greatly enhancing the overall stability.

[0012] Further, the lower wave trough section, the upper wave trough section and the lower chord steel bar on the same side are all arranged in the corresponding first placement groove and the second placement groove.

[0013] By adopting the above technical solution, under the blocking cooperation of the first placement groove and the first convex edge, and the second placement groove and the second convex edge, the corresponding web steel bars and lower chord steel bars on both sides can be clamped therein.

[0014] Further, the connecting part includes grooves opened on both sides of the upper surface of the bottom plate, and a fixing plate is clamped in the grooves.

[0015] By adopting the above technical solution, when two bottom plates are spliced, the fixing plate can be clamped in the grooves, so that the two bottom plates can be fixed without welding, saving time and effort.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Through the arrangement of the placement groove, the first convex edge and the second convex edge, the wave trough sections of the lower chord steel bars and the web steel bars can be placed in the placement groove. At the same time, the first convex edge and the second convex edge can block the wave trough sections of the lower chord steel bars and the web steel bars. There is no need to rigidly weld the bottom plate and the lower chord steel bars, so that the lower chord steel bars and the web steel bars have a certain activity space, avoiding the welding opening caused by the excessive weight of the concrete during pouring.

[0018] 2. By providing the web bars, the lower trough section and the upper trough section of the web bars firmly weld the lower chord bars in the middle, changing the single-sided welding of the lower chord bars to double-sided welding. At the same time, the upper chord bars are also welded between the peak sections of the web bars, enabling two lower chord bars, one upper chord bar, and the web bars to form a triangular shape with the bottom plate, having a certain stability and greatly enhancing the overall stability.

[0019] 3. By providing the connecting part, when splicing two bottom plates, the fixing plate can be clamped in the groove, enabling the two bottom plates to be fixed without welding, saving time and effort.

[0027] Referring to Figures 1-3 , an embodiment of the present utility model provides a strong and rigid steel truss bearing plate system, including a bottom plate 1. An installation groove 11 is provided on the upper surface of the bottom plate 1. The installation groove 11 includes an installation groove one 111 and an installation groove two 112. The upper ends of the installation groove one 111 and the installation groove two 112 are respectively a convex edge one 12 and a convex edge two 13 extending from both sides of the bottom plate 1 towards the middle.

[0028] Referring to Figures 1-3 , a steel bar assembly 2 is provided on the bottom plate 1. The steel bar assembly 2 includes two lower chord steel bars 21 respectively arranged in the installation groove one 111 and the installation groove two 112. Web steel bars 22 are respectively welded on the two lower chord steel bars 21. The two web steel bars 22 are in a wave shape. The web steel bars 22 are divided into a wave crest section 221 and a wave trough section 222. An upper chord steel bar 23 is welded between the wave crest sections 221 of the two web steel bars 22. The two lower chord steel bars 21, one upper chord steel bar 23, and the web steel bars 22 can form a triangular shape with the bottom plate 1, having a certain stability. The wave trough section 222 is divided into a lower wave trough section 2221 and an upper wave trough section 2222. The lower wave trough section 2221 is located at the lower end of the lower chord steel bar 21, and the upper wave trough section 2222 is located at the upper end of the lower chord steel bar 21. The lower chord steel bar 21 is welded and fixed in the middle of the lower wave trough section 2221 and the upper wave trough section 2222. The lower wave trough section 2221 and the upper wave trough section 2222 firmly weld the lower chord steel bar 21 in the middle, making the lower chord steel bar 21 change from single-sided welding to double-sided welding, greatly enhancing the overall stability.

Under the blocking and cooperation of the installation groove one 111 and the convex edge one 12, and the installation groove two 112 and the convex edge two 13, the corresponding web steel bars 22 and the lower chord steel bars 21 on both sides can be clamped therein, so that the lower chord steel bar 21 and part of the web steel bars 22 do not need to be fixed to the bottom plate 1 by rigid welding. The lower chord steel bar 21 and part of the web steel bars 22 can have a certain activity space through the blocking of the convex edge one 12 and the convex edge two 13.

[0029] Referring to Figures 1-3, connecting parts 3 are also provided on both sides of the bottom plate 1. The connecting part 3 includes grooves 31 opened on both sides of the upper surface of the bottom plate 1. A fixing plate 32 is engaged in the groove 31. When two bottom plates 1 are spliced, the fixing plate 32 is slid into the groove 31 from one side, so that the fixing plate 32 is engaged in the groove 31. Further, the two bottom plates 1 can be fixedly connected by engaging the fixing plate 32, so that the two bottom plates 1 can be fixed without welding, which saves time and effort.

[0030] The specific implementation manner is as follows: During use, the welded steel bar assembly 2 is slid into the groove 31 of the prefabricated bottom plate 1, so that the trough section 222 of the lower chord steel bar 21 and the web steel bars 22 wound around the upper trough section 2222 and the lower trough section 2221 are placed in the placement groove 11, and are engaged in the placement groove 11 under the blocking of the first convex edge 12 and the second convex edge 13. There is no need to rigidly weld the bottom plate 1 and the lower chord steel bar 21 together, effectively avoiding the welding opening caused by the excessive weight of the concrete during concrete pouring. At the same time, when splicing the bottom plates 1, the fixing plate 32 is slid into the groove 31, so that the plate body of the fixing plate 32 is engaged in the groove 31 and is adapted to the shape of the groove 31, achieving the purpose of fixing the two bottom plates 1 without welding, which saves time and effort.
