Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0032] In view of the problems of long construction period and large initial investment of pre-fixed structures in related technologies, the utility model provides a steel truss floor deck support.

[0033] The following combination Figure 1 , describing the embodiments of the present utility model.

[0034] According to the embodiment of the present utility model, Figure 1 As shown, a steel truss floor deck support is provided, including: a support body 1, embedded parts 2 and connecting parts 3.

[0036] The embodiment of the present invention makes the first fixed plate 101 contact the lower surface of the steel truss floor deck 4, and at the same time makes the second fixed plate 102 fit tightly with the side wall of the cast-in-place structure 5, which can provide sufficient support force for the steel truss floor deck 4, improve the stability of the steel truss floor deck 4 during the casting process, and reduce quality problems caused by displacement or deformation. Furthermore, the embedded parts 2 are pre-set in the cast-in-place structure 5, and the second fixed plate 102 is connected to the embedded parts 2 through the connecting parts 3. Such an arrangement can, on the one hand, simplify the on-site installation steps, shorten the construction period, and improve construction efficiency; on the other hand, it can firmly set the support body 1 on the cast-in-place structure 5 to ensure the connection quality between the steel truss floor deck 4 and the cast-in-place structure 5. It can be seen that the support structure of the embodiment of the present invention is simple and easy to install, which can not only effectively shorten the construction period, but also reduce the initial investment cost.

[0037] It should be noted that the cast-in-situ structure 5 in this embodiment can be a cast-in-situ beam or a shear wall.

[0038] According to one embodiment of the present invention, a groove is provided on the embedded part 2, and an internal thread is provided on the groove wall of the groove, and the notch of the groove is suitable for abutting against the second fixed plate 102; the connecting member 3 is a bolt, and the screw of the bolt passes through the second fixed plate 102 and is screwed into the internal thread. By providing an internal thread on the groove wall of the embedded part 2 and setting the connecting member 3 as a bolt, the embodiment of the present invention can achieve a detachable connection between the second fixed plate 102 and the cast-in-place structure 5. On the one hand, it can simplify the installation process between the second fixed plate 102 and the cast-in-place structure 5 and shorten the construction period; on the other hand, it can simplify the disassembly process between the second fixed plate 102 and the cast-in-place structure 5, realize the recycling of the support body 1 and the connecting member 3, and reduce the amount of capital investment. Furthermore, the embodiment of the present invention makes the notch of the groove abut against the second fixed plate 102, which can prevent the groove from being blocked by concrete or other foreign matter, and ensure that the bolt can be screwed into the internal thread smoothly. In addition, since the groove on the embedded part 2 does not penetrate the cast-in-place structure 5, the complexity of the subsequent repair work on the side wall of the cast-in-place structure 5 can be reduced, and the capital expenditure during the repair work can be reduced.

[0039] According to one embodiment of the present invention, the embedded part 2 is provided with a groove, and a fixing nut 2011 is provided in the groove. The notch direction of the groove is consistent with the axial direction of the fixing nut 2011, and the notch of the groove is suitable for abutting the second fixing plate 102. The connecting member 3 is a bolt, and the screw of the bolt passes through the second fixing plate 102 and is screwed into the fixing nut 2011. By providing the fixing nut 2011 in the groove and configuring the connecting member 3 as a bolt, the embodiment of the present invention can achieve a stable connection between the connecting member 3 and the embedded part 2, firmly attaching the second fixing plate 102 to the cast-in-place structure 5, and ensuring that the first fixing plate 101 can provide sufficient support for the steel truss floor deck 4. In addition, the combination of the bolt and the fixing nut 2011 can simplify the installation process and improve construction efficiency. It can also facilitate the easy disassembly of the connecting member 3 and the support body 1 at a later time, enabling the support body 1 and the connecting member 3 to be recycled. Furthermore, aligning the notch of the groove with the axial direction of the fixing nut 2011 and abutting the notch of the groove against the second fixing plate 102 helps ensure that the bolt's screw can be smoothly and accurately inserted into the fixing nut 2011, reducing construction errors. Furthermore, because the groove on the embedded part 2 does not penetrate the cast-in-place structure 5, the complexity of subsequent repair work on the side wall of the cast-in-place structure 5 can be reduced, reducing the cost of the repair work.

[0040] According to one embodiment of the present utility model, the embedded part 2 includes a fixing portion 201 and a guide portion 202, a fixing nut 2011 is provided in the fixing portion 201, and a guide through hole 2021 is provided in the guide portion 202, the guide through hole 2021 extends along the axial direction of the fixing nut 2011 and is suitable for abutting against the second fixing plate 102; the connecting member 3 includes a double-headed screw 301 and a fastening nut 302, one end of the double-headed screw 301 passes through the second fixing plate 102, so the guide through hole 2021 is screwed to the fixing nut 2011, and the other end is fixed to the second fixing plate 102 by the fastening nut 302. The embodiment of the present invention provides a fixing nut 2011 within the fixing portion 201 and configures the connector 3 as a stud screw 301 and a fastening nut 302. This allows the connector 3 to be stably connected to the embedded component 2, and the second fixing plate 102 to be securely mounted on the sidewall of the cast-in-place structure 5 through the cooperation of the fastening nut 302 and the stud screw 301. Furthermore, since the stud screw 301, the fastening nut 302, and the fixing nut 2011 are all threaded together, rapid installation and removal are possible, improving work efficiency. Furthermore, by providing a guide portion 202 connected to the fixing portion 201 and providing a guide through hole 2021 within the guide portion 202, and allowing the guide through hole 2021 to extend axially along the fixing nut 2011 and abut against the second fixing plate 102, it is possible to ensure that the stud screw 301 can smoothly pass through the guide portion 202 and achieve rapid docking with the fixing nut 2011. In addition, since the fixing portion 201 on the embedded part 2 does not penetrate the cast-in-place structure 5, the complexity of the subsequent repair work on the side wall of the cast-in-place structure 5 can be reduced, and the capital expenditure during the repair work can be reduced.

[0041] It should be noted that, in this embodiment, the size of the double-headed screw 301 may be M16*80.

[0042] According to one embodiment of the present invention, an extension portion is provided on a side of the fixing portion 201 away from the guide portion 202, and the extension portion is connected to the guide through hole 2021. By providing the extension portion on the side of the fixing portion 201 away from the guide portion 202 and connecting the extension portion to the guide through hole 2021, the present embodiment of the present invention allows one end of the stud screw 301 to extend into the extension portion. This allows the stud screw 301 to be fully threadedly engaged with the fixing nut 2011 in the fixing portion 201, thereby improving the connection strength between the two.

[0043] According to one embodiment of the present invention, a rotating portion is provided at one end of the double-headed screw 301 away from the embedded part 2, and an axial through hole is provided in the rotating portion. The axial direction of the axial through hole is perpendicular to the axial direction of the double-headed screw 301. The fastening nut 302 is sleeved on the double-headed screw 301 and is located between the second fixing plate 102 and the rotating portion. By providing a rotating portion at the end of the double-headed screw 301 away from the embedded part 2, the embodiment of the present invention can make it easier for workers to rotate the double-headed screw 301, thereby completing the tightening or loosening operation of the double-headed screw 301. Furthermore, an axial through hole is provided in the rotating portion, and the axial direction of the axial through hole is perpendicular to the axial direction of the double-headed screw 301. This allows workers to insert different tools, such as a connecting rod, into the axial through hole as needed, that is, a lever structure can be constructed to increase the torque when tightening or loosening the double-headed screw 301, making the operation more labor-saving and convenient. In addition, the fastening nut 302 is sleeved on the stud screw 301 and located between the second fixing plate 102 and the rotating part, so that the fastening nut 302 can fix the second fixing plate 102 on the side wall of the cast-in-place structure 5.

[0044] According to one embodiment of the present invention, the inner wall of the axial through hole is provided with internal threads. By providing internal threads on the inner wall of the axial through hole, this embodiment of the present invention can be matched with corresponding externally threaded tools (such as bolts, screws, etc.), thereby achieving a more stable connection. This effectively prevents slippage or loosening when tightening or loosening the stud screw 301, ensuring the stability and reliability of the connection.

[0045] According to one embodiment of the present invention, the embedded part 2 is made of plastic. By making the embedded part 2 of plastic, the present invention reduces the manufacturing cost of the embedded part 2. Furthermore, because plastic generally has good corrosion resistance, the embedded part 2 maintains stable performance during the casting of the cast-in-place structure 5, thereby improving the connection stability between the connector 3 and the embedded part 2 and ensuring that the second fixing plate 102 is securely fixed to the side wall of the cast-in-place structure 5.

[0046] According to one embodiment of the present invention, the first fixing plate 101 and the second fixing plate 102 are integrally formed. The integrally formed design of the support body 1 of the present embodiment improves its structural strength, providing sufficient support for the steel truss floor deck 4, and reduces the number of parts and assembly steps.

[0047] According to one embodiment of the present invention, the support body 1 is angle steel. This utilizes the stability of the support body 1 to effectively withstand the forces acting on the steel truss deck 4. Furthermore, angle steel, as a commonly used building material, is relatively inexpensive, effectively reducing initial capital expenditures.

[0048] It should be noted that the angle steel size in this embodiment can be L75*5.
