Description

Technical Field

[0001] The utility model relates to the technical field of floor decking, in particular to a V-shaped single-edge folded steel bar truss floor decking. Background Art

[0002] V-shaped single-folded steel truss floor deck is a unique building formwork material. It uses steel bars as the main skeleton and is connected into a load-bearing plate by welding or binding. This floor deck has the characteristics of light weight, high strength, and good fire resistance. It is widely used in the construction of floor beam-column nodes in various buildings. Its structural form is a mesh composite beam, forming a triangular or trapezoidal plane component, which is subjected to longitudinal and transverse forces, and has excellent bearing capacity and seismic resistance. The steel truss floor deck is not only simple and quick to construct, but also has a low comprehensive cost, is green and environmentally friendly, and has a beautiful appearance. It is an ideal product to replace ordinary reinforced concrete.

[0003] Through research and analysis, it is found that the existing steel truss floor decking or traditional floor decking has certain defects in the construction process. Although the current floor decking design can adjust the position of steel bars and the height of steel trusses, simplify the splicing process, and improve construction efficiency, it still fails to effectively solve the problem of chaotic layout of water and electricity pipelines, and the problem that pipelines are easily damaged in subsequent construction. In addition, although the existing connection method simplifies the installation, it may have the problem of insufficient stability, and additional connectors and protective measures are required to ensure the connection and sealing of the connection parts. These technical shortcomings limit the space utilization efficiency and construction safety of the floor decking system. In actual construction, there may be potential problems such as unreasonable pipeline routing, easy damage to pipelines, and leakage at the connection parts, which affect the overall construction quality and efficiency. Therefore, it is necessary to improve the shortcomings and defects of the existing technology. Utility Model Content

[0028] like Figure 4 As shown, the steel truss 2 includes a lower chord steel bar 21 and an upper chord steel bar 22. There are two lower chord steel bars 21 in total. The two lower chord steel bars 21 and the upper chord steel bar 22 at the top form an isosceles triangle structure. The waist of the triangle structure formed by the lower chord steel bars 21 and the upper chord steel bars 22 is welded and fixed with web bars 23. A plurality of frame bars 24 are welded and fixed along the axial direction in the triangle structure formed by the lower chord steel bars 21 and the upper chord steel bars 22.

[0029] like Figure 8 As shown, a slider 41 is provided on the position adjustment component 4, and the slider 41 is slidably connected to the upper side of the steel bar 3. A convex plate 42 is fixed on the outer side of the slider 41, and an L-shaped plate 43 is fixed on the upper side of the convex plate 42. A pull rod 44 is slidably connected to the L-shaped plate 43, and the pull rod 44 penetrates the convex plate 42 downward. A disc 45 is fixed on the axial outer side of the pull rod 44, and the disc 45 is located in the concave area formed by the L-shaped plate 43 and the convex plate 42. A spring 46 is sleeved on the axial outer side of the L-shaped plate 43, and the spring 46 is located on the upper side of the disc 45 and in the concave area.

[0030] like Figure 5 As shown, a plurality of positioning holes 31 are evenly distributed along the axial direction on the upper side of the steel bar 3 , and the bottom of the pull rod 44 is fixed to the positioning hole 31 by plugging.

[0031] Embodiment 2:

[0032] The difference between this embodiment and embodiment 1 is that:

[0033] like Figure 6 As shown, the connecting lock buckle 7 is provided with a fixing plate 1 71, a fixing plate 2 72, and a spring 2 75. The fixing plate 1 71 is fixedly connected to the mounting groove on the convex opening 13, and the fixing plate 2 72 is fixedly connected to the mounting groove on the concave opening 14. An integrally formed cylinder 73 is fixed to the outer side of the fixing plate 1 71, and two symmetrically arranged arc-shaped clips 74 are rotatably connected inside the fixing plate 2 72. The spring 2 75 is connected and fixed between the flange plate of the arc-shaped clip 74 and the fixing plate 2 72.

[0034] like Figure 3 , Figure 7 As shown, sealing strips are attached to the connecting portion between the upper notch 11 and the lower notch 12 and the connecting portion between the convex opening 13 and the concave opening 14 .

[0035] like Figure 1 As shown, the inner diameter of the tightening hoop 5 can be adjusted to meet the fixing needs of the outer protective tube 6 with different diameters. The outer protective tube 6 can be used for the routing of water supply and drainage, power supply cables, and weak current cables.

[0036] Working principle: During the production and manufacturing process of the floor decking body, the production personnel can adjust the fixed position and quantity of the steel bars 3 on the bottom plate 1 according to the different design drawings of the project, so as to meet the needs of laying water and electricity pipelines in actual construction, and the overall height of the steel truss 2 can also be adjusted accordingly according to the thickness of the building floor slab; during the construction process, the floor decking body is transported to the designated construction site, and the construction personnel install the floor decking body in sequence, and the short sides of adjacent floor deckings are connected by the upper notch 11 and the lower notch 12, and the long sides of adjacent floor deckings are connected by the convex opening 13 and the concave opening 14, and the sealing strips pasted at the connection parts of adjacent floor deckings play a sealing role to prevent gaps in the connection parts and leakage. Figure 1 , Figure 6 As shown, when the long sides of adjacent floor deck bodies are spliced, the cylinder 73 on the connecting lock buckle 7 will push open the two arc-shaped clips 74 rotating on the fixing plate 2 72, so that the cylinder 73 is stuck in the notch formed by the two arc-shaped clips 74. Under the elastic restoring force of the springs 2 75 on both sides, the cylinder 73 can be firmly stuck on the inner side of the arc-shaped clip 74. The design of the connecting lock buckle 7 enables the two floor deck bodies to be automatically locked when spliced, thereby enhancing the overall stability of the floor slab. This design does not require additional fasteners, simplifies the installation process, and improves construction efficiency.

[0037] like Figure 8 As shown, according to the different water and electricity pipelines to be installed, the pull rod 44 on the position adjustment component 4 can be pulled upward to compress the spring 46 upward, thereby releasing the plug-in fixing relationship between the pull rod 44 and the positioning hole 31, so that the position adjustment component 4 can move horizontally on the upper side of the steel bar 3. After adjusting the position adjustment component 4 to a suitable position, the upward pulling force of the pull rod 44 is released, and the pull rod 44 can be locked with the positioning hole 31 under the action of the downward elastic restoring force of the spring 46. Subsequently, multiple tightening hoops 5 can be used to tighten the outer protective tubes 6 of different outer diameters. When laying pipelines, routing the water and electricity pipelines through the outer protective tube 6 can play an effective protective role and avoid pressure damage to the water and electricity pipelines during the subsequent upper steel bar binding and concrete pouring process. This design improves the orderly use of the space on the upper side of the base plate 1, avoids the chaos existing in the traditional water and electricity pipeline laying, and can quickly adjust the layout according to project requirements.
