[0019] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.
[0020] like Figure 1 As shown, this embodiment provides a steel truss floor deck, including a bottom formwork 1 and a steel truss 3. Several mounting seats 2 are detachably connected to the bottom formwork 1, and the steel truss 3 is snapped onto the mounting seats 2. Several first insertion holes 101 are provided at intervals on opposite sides of the bottom formwork 1. It also includes a waterproof strip 4, which has several second insertion holes at intervals. It also includes a reinforcing bar 5, which passes through the first insertion holes 101 and the second insertion holes to connect and fix two adjacent steel truss floor decks and the waterproof strip 4 between them. The steel truss 3 includes supporting reinforcing bars 301 located on both sides. The supporting reinforcing bars 301 are wavy, and the crests of the two supporting reinforcing bars 301 intersect each other and are welded to the first reinforcing bar 302. The bottom of the supporting reinforcing bars 301 is welded with a second reinforcing bar 303.
[0021] like Figure 2 , Figure 3 As shown, the assembly base 2 includes a long strip-shaped support block 201. A first retainer 2011 and a second retainer 2012 are provided at both ends of the support block 201. The first retainer 2011 has a C-shaped structure, with the C-shaped opening located near the second retainer 2012 for engaging the second reinforcing rib 303. The second retainer 2012 has a V-shaped structure, with a V-shaped through hole 203 located below the V-shaped opening. The bottom of the V-shaped opening connects to the corner of the V-shaped through hole 203, forming a structure for holding the second reinforcing rib 303. The rib 303 has a rib insertion groove; the bottom of the first card holder 2011 and the second card holder 2012 are both provided with pads 202, which are made of plastic. The bottom template 1 is provided with two threaded holes 102 corresponding to each pre-installation position of the assembly seat 2. The bottom of the pad 202 is provided with a threaded groove; the bottom of the bottom template 1 is also provided with an assembly groove outside the threaded hole 102; when the assembly seat 2 is connected to the bottom template 1, the bolt shank of the connecting bolt passes through the threaded hole 102 from bottom to top and is threaded into the threaded groove, and the bolt head of the connecting bolt is submerged in the assembly groove.
[0022] During the transportation, the bottom formwork 1, the steel bar truss 3 and the assembling seat 2 can be transported separately by vehicles, so that the bending and deformation of the steel bar truss 3 during the transportation of the integrated steel bar truss 3 floor support plate can be avoided. After being transported to the site, the assembling seat 2 is connected to the bottom formwork 1 through the connecting bolts, and then the steel bar truss 3 is pinched, so that the two second reinforcing bars 303 at the bottom of the two supporting steel bars 301 are close to each other, one second reinforcing bar 303 is placed at one side of the C-shaped opening of the first clamping seat 2011, and the other second reinforcing bar 303 is inserted into the inserted rib groove of the second clamping seat 2012. After the concrete is formed in the later period, the inserted rib 5 is pulled out after the demolding condition is reached, and the bottom formwork 1 can be removed by disassembling the connecting bolts.
[0023] The anti-seepage water stop strip 4 is an oak strip. Due to the physical properties of the oak strip, deformation will occur during the thermal reaction of the concrete, so that a gap will be re-formed between the bottom formwork 1 and the bottom formwork 1 after the concrete is solidified, so that the bottom formwork 1 can be easily disassembled. Figure 4 The bottom formwork 1 is provided with a pick-up hole, and one side of the two opposite sides is provided with a pick-up table 6. The pick-up table 6 comprises a bottom pick-up plate 601 and two end plates 602 located at the front and rear ends of the bottom pick-up plate 601, and the anti-seepage water stop strip 4 is installed in the pick-up table 6. By arranging the pick-up table 6, the oak strip can be prevented from leaking mortar from the bottom or the end after dehydration and shrinkage.
[0024] The steel bar truss 3 floor support plate in the new type has low manufacturing cost, is convenient for transportation, assembly and disassembly, avoids the leakage of mortar at the welding points of the steel bar truss 3 and the bottom formwork 1, and solves the problem of leakage of mortar caused by the joint of the floor support plate, which is helpful to ensure the construction quality and the construction period.
[0025] The above only describes the preferred embodiments of the present application, and is not limited to the scope of the present application. Any equivalent changes made according to the content of the present application and the drawings are included in the scope of the present application.
