Description

Technical Field

[0001] This utility model belongs to the technical field of steel truss floor deck installation, specifically a steel truss floor deck docking and positioning clamp. Background Technology

[0002] Steel truss floor decking is a type of unsupported profiled composite floor decking. The steel truss is prefabricated in the back-end processing yard. On-site construction requires first fixing the profiled sheets to the steel beams with studs, then placing and binding the steel truss, and finally pouring concrete after acceptance. When constructing large-span steel truss floor decking, temporary supports need to be added at the mid-span, and these temporary supports need to be positioned and connected.

[0003] A Chinese patent with publication number CN105064720A discloses a self-supporting steel truss floor deck support structure, including a steel truss floor deck and a support component located below the steel truss floor deck. The support component abuts against the galvanized steel plate and is supported directly below a portion of several contact points between the web reinforcement and the galvanized steel plate, which is the support portion of the lower end face of the galvanized steel plate. Fasteners are provided at the contact points between the web reinforcement and the galvanized steel plate, excluding the contact points directly above the support portion. Compared with the prior art, this technical solution effectively ensures the thickness of the reinforcing steel protective layer, effectively reduces the deformation of the galvanized steel formwork, and facilitates the reuse of the steel formwork in the later stage; the flatness and appearance quality of the concrete floor slab are greatly improved.

[0004] While current technologies have greatly improved the appearance and quality of concrete floor slabs, the lack of positioning clamps on the steel pipes for support, and the absence of connections between adjacent steel pipes, means that the steel pipes are supported only by the concrete at the bottom. When the steel pipes are high, this may lead to instability of the base and the risk of tipping over.

[0005] Therefore, a positioning clamp for connecting steel truss floor deck slabs is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the problem of no connection between two adjacent steel pipes, we propose a steel truss floor decking docking positioning clamp.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The steel truss floor decking docking positioning clamp of this utility model includes multiple uprights, each upright being fixedly connected to multiple connecting discs, and each connecting disc having eight alignment holes; a horizontal rod joint is inserted into one side of four of the alignment holes, and a horizontal rod pin is inserted into each of the horizontal rod joints, with the horizontal rod pins penetrating through the alignment holes and inserted to the bottom of the horizontal rod joints, and a horizontal rod body is fixedly connected between two adjacent horizontal rod joints; a diagonal rod joint is inserted into one side of the remaining four alignment holes, and a diagonal rod pin is inserted into each of the diagonal rod joints, with the diagonal rod pins penetrating through the alignment holes and inserted to the bottom of the diagonal rod joints, and a diagonal rod body is fixedly connected between two diagonal rod joints of different heights.

[0008] Preferably, the bottom of each horizontal rod pin is fitted with a horizontal rod sealing ring, and the bottom of each diagonal rod pin is fitted with a diagonal rod sealing ring.

[0009] Preferably, each of the uprights is welded to a mounting base, and each mounting base is fixed to a square timber. A template is provided above the square timber, and each is fixed to the bottom of the template with nails.

[0010] Preferably, the top of the template is provided with multiple buckles, the bottom of each buckle is installed on the template by fastening bolts, and a truss assembly is installed on the buckle.

[0011] Preferably, the truss assembly includes two lower chord steel bars symmetrically arranged at the bottom of the buckle. The lower chord steel bars are fixed to the buckle by welding. Diagonal steel bars are installed on the lower chord steel bars by welding. An upper chord steel bar is provided between two adjacent diagonal steel bars. The top of the diagonal steel bar is welded to the upper chord steel bar.

[0012] Preferably, both the horizontal bar body and the diagonal bar body adopt an adjustable structure. The adjustable structure includes two layers of telescopic tubes, and the connection between the two layers of telescopic tubes is connected by a locking screw, which is used to adjust the length of the horizontal bar body and the diagonal bar body.

[0013] The beneficial effects of this utility model are: This utility model provides a positioning clamp for butt joints of steel truss floor decking. By setting up a horizontal bar body and a diagonal bar body, when two adjacent uprights need to be butt-fixed through the horizontal bar body, the horizontal bar joint needs to be inserted into the corresponding alignment hole position, and then fixed by the horizontal bar pin. When two adjacent uprights need to be butt-fixed through the diagonal bar body, the diagonal bar joint needs to be inserted into the corresponding alignment hole position, and then fixed by the diagonal bar pin. The heights of the diagonal bar joints are different. The horizontal bar body and the diagonal bar body give the uprights good stability.

[0014] This utility model provides a positioning clamp for butt joints of steel truss floor decking. By setting upper chord steel bars, lower chord steel bars, and diagonal steel bars, the truss assembly formed can effectively ensure the thickness of the protective layer of the infill formwork, effectively reduce the deformation of the formwork, and facilitate the reuse of the formwork in the later stage. The truss assembly is installed on the formwork by setting buckles, and the installation is facilitated by fastening bolts, which makes it easy to disassemble later.

[0015] This utility model provides a positioning clamp for connecting steel truss floor decks. By setting an adjustable structure, when the length between two uprights needs to be adjusted, it can be stretched to a suitable length by stretching two telescopic tubes and then fixed by locking screws. This improves the applicability of the horizontal bar body and the diagonal bar body, avoids frequent replacement of uprights of different lengths, and avoids reducing construction efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Example 1: Please see Figures 1-7 This utility model provides a positioning clamp for butt joints of steel truss floor decking, including multiple uprights 22, each upright 22 being fixedly connected to multiple connecting discs 23, each connecting disc 23 having eight alignment holes; four of the alignment holes have horizontal bar joints 24 inserted on one side, each horizontal bar joint 24 having a horizontal bar pin 242 inserted thereon, the horizontal bar pin 242 passing through the alignment hole and inserted to the bottom of the horizontal bar joint 24, and a horizontal bar body 241 fixedly connected between two adjacent horizontal bar joints 24; the remaining four alignment holes have diagonal bar joints 25 inserted on one side, each diagonal bar joint 25 having a diagonal bar pin 252 inserted thereon, the diagonal bar pin 252 passing through the alignment hole and inserted to the bottom of the diagonal bar joint 25, and a diagonal bar body 251 fixedly connected between two diagonal bar joints 25 of different heights.

[0020] During operation, to address the lack of connection between adjacent steel pipes, when two adjacent uprights 22 need to be connected and fixed via the horizontal bar body 241, the horizontal bar connector 24 needs to be inserted into the corresponding alignment hole and then fixed via the horizontal bar pin 242. Similarly, when two adjacent uprights 22 need to be connected and fixed via the diagonal bar body 251, the diagonal bar connector 25 needs to be inserted into the corresponding alignment hole and then fixed via the diagonal bar pin 252. The diagonal bar connectors 25 have different heights. The horizontal bar body 241 and diagonal bar body 251 provide excellent stability for the uprights 22. The outer surfaces of the horizontal bar body 241 and diagonal bar body 251 are hot-dip galvanized for corrosion protection, ensuring durability, high turnover rate, and cost savings. They are made of low-alloy high-strength steel, providing high load-bearing capacity. Considering the safety factor, the single-limb design load-bearing capacity can reach over 40KN. They require less material, are quick and easy to install, and are highly efficient.

[0021] Furthermore, such as Figure 4 As shown, the bottom of each horizontal rod pin 242 is fitted with a horizontal rod sealing ring 243, and the bottom of each inclined rod pin 252 is fitted with an inclined rod sealing ring 253.

[0022] During operation, a horizontal rod sealing ring 243 is fitted at the bottom of the horizontal rod pin 242 and a diagonal rod sealing ring 253 is fitted at the bottom of the diagonal rod pin 252 to prevent the horizontal rod pin 242 and the diagonal rod pin 252 from falling off accidentally, and the installation and disassembly are both convenient.

[0023] Furthermore, such as Figure 2 As shown, each of the uprights 22 has a mounting base 21 welded to its top, and each mounting base 21 has a square timber 2 fixed to its top. A template 1 is provided above the square timber 2, and both are fixed to the bottom of the template 1 with nails.

[0024] During operation, the top of the upright 22 is fixed by the mounting base 21 and the square timber 2, and then the template 1 is fixed to the square timber 2 with iron nails to support the template 1. The square timber 2 includes different heights to facilitate the adjustment of the template 1 to a horizontal position.

[0025] Example 2: Furthermore, such as Figure 7 As shown, the mounting base 21 is threadedly connected to the top of the upright 22 via a threaded rod.

[0026] During operation, when the size of the square timber 2 is fixed, the length of the upright 22 is adjusted by the threaded rod to achieve fine adjustment of the upright 22 of different lengths, so that the upright 22 can be inserted on uneven ground, and ultimately ensure that the template 1 is level.

[0027] Example 3: Furthermore, such as Figure 5 As shown, the top of the template 1 is provided with multiple buckles 3, and the bottom of each buckle 3 is installed on the template 1 by fastening bolts 34. A truss assembly is installed on the buckle 3.

[0028] During operation, the truss assembly is installed on the template 1 by setting the buckle 3, and is installed by fastening the bolts 34, which facilitates disassembly later.

[0029] Furthermore, such as Figure 5 and Figure 6 As shown, the truss assembly includes two lower chord steel bars 31 symmetrically arranged at the bottom of the buckle 3. The lower chord steel bars 31 are both fixed to the buckle 3 by welding. Diagonal steel bars 33 are installed on the lower chord steel bars 31 by welding. An upper chord steel bar 32 is provided between two adjacent diagonal steel bars 33. The top of the diagonal steel bar 33 is welded to the upper chord steel bar 32.

[0030] During operation, the truss formed by the upper chord steel bar 32, the lower chord steel bar 31 and the diagonal steel bar 33 can effectively ensure the thickness of the protective layer of the infilled formwork 1, effectively reduce the deformation of the formwork 1, and facilitate the reuse of the formwork 1 in the later stage.

[0031] Furthermore, such as Figure 4 As shown, both the horizontal bar body 241 and the diagonal bar body 251 adopt an adjustable structure. The adjustable structure includes two layers of telescopic tubes, and the connection between the two layers of telescopic tubes is connected by a locking screw, which is used to adjust the length of the horizontal bar body 241 and the diagonal bar body 251.

[0032] During operation, both the horizontal bar body 241 and the diagonal bar body 251 adopt an adjustable structure. When the length between the two uprights 22 needs to be adjusted, it can be stretched to a suitable length by stretching the two telescopic tubes and then fixed by locking screws. This improves the usability of the horizontal bar body 241 and the diagonal bar body 251, avoids frequent replacement of uprights 22 of different lengths, and reduces construction efficiency.

[0033] Working principle: To solve the problem of no connection between two adjacent steel pipes, when two adjacent uprights 22 need to be connected and fixed through the horizontal bar body 241, the horizontal bar connector 24 needs to be inserted into the corresponding alignment hole, and then fixed by the horizontal bar pin 242; when two adjacent uprights 22 need to be connected and fixed through the diagonal bar body 251, the diagonal bar connector 25 needs to be inserted into the corresponding alignment hole, and then fixed by the diagonal bar pin 252, and the heights of the diagonal bar connectors 25 are different; the horizontal bar body 241 and the diagonal bar body 251 give the uprights 22 good stability; by fitting a horizontal bar sealing ring 243 at the bottom of the horizontal bar pin 242 and a diagonal bar sealing ring 253 at the bottom of the diagonal bar pin 252, the horizontal bar pin 242 and the diagonal bar pin 252 are prevented from falling off accidentally, and installation and disassembly are both convenient.

[0034] The truss, formed by the upper chord reinforcement 32, lower chord reinforcement 31, and diagonal reinforcement 33, effectively ensures the thickness of the protective layer of the infill formwork 1, effectively reduces the deformation of the formwork 1, and facilitates the reuse of the formwork 1 in the later stage. Clips 3 are used to install the truss components onto the formwork 1, and fastening bolts 34 are used for installation, facilitating subsequent disassembly.

[0035] Both the horizontal bar body 241 and the diagonal bar body 251 adopt an adjustable structure. When the length between the two uprights 22 needs to be adjusted, it can be stretched to a suitable length by stretching the two telescopic tubes and then fixed by locking screws. This improves the usability of the horizontal bar body 241 and the diagonal bar body 251, avoids frequent replacement of uprights 22 of different lengths, and reduces construction efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
