Description

Technical Field

[0001] This utility model relates to the field of modular steel bar hoisting technology, and in particular to a temporary support device suitable for vertical modular steel bar mesh. Background Technology

[0002] For the construction of large-volume concrete components, the current main approach to improve construction efficiency and reduce the safety risks of working at heights is the modular construction method using steel reinforcement. However, this modular method is primarily suitable for structures with a large number of identical components, a high degree of standardization in structural dimensions, and ample space for joint connections. Some large-volume, irregularly shaped structures are characterized by "exceptionally dense reinforcement, numerous intersecting areas of reinforcement, and varied structural shapes," making large-scale modular steel reinforcement construction unsuitable. Therefore, another method is to convert large-volume steel reinforcement components into modular steel mesh units for installation. This involves first binding and installing the steel mesh in a fixed location, and then using cranes to transport the mesh to the designated location for installation. This saves significant time and reduces the need for transportation equipment.

[0003] However, after the steel mesh is installed but before concrete pouring, its relatively low planar stiffness makes it prone to overturning. Therefore, it needs to be supported outside the plane. Traditional support methods use single-limb angle steel as diagonal braces and connect them to the steel mesh via spot welding. This spot welding method is not very secure, resulting in low construction efficiency and a risk of breakage. Furthermore, welding can damage the steel cross-section, affecting the structure's load-bearing capacity. Additionally, because the support is made of single-limb angle steel, its out-of-plane stability is poor, making it prone to buckling under load, posing a high safety risk. Utility Model Content

[0004] The purpose of this invention is to provide a temporary support device suitable for vertical modular steel mesh, which solves the problems of low efficiency and high safety risks in traditional steel mesh support and positioning devices.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a temporary support device for vertical modular steel mesh, comprising a support assembly and a steel mesh connecting sleeve. The support assembly is obliquely disposed outside the installed steel mesh and includes two support rods. The two support rods clamp the steel mesh to be installed and the installed steel mesh together and lock them in place by the connecting assembly. The steel mesh connecting sleeve is disposed on the end of the steel bar of the installed steel mesh. The end of the steel bar to be installed is vertically inserted into the steel mesh connecting sleeve and fixed by compression.

[0007] Furthermore, the two support rods are configured as back buckles, and a gap is provided between the two support rods.

[0008] Furthermore, the support rod includes a first support rod body and a second support rod body that are vertically connected together; the gap is provided between the two second support rod bodies.

[0009] Furthermore, several gusset plates are provided within the gap.

[0010] Furthermore, the distance between two adjacent connecting plates is no more than 1m.

[0011] Furthermore, several of the aforementioned support components are arranged along the length of the steel mesh to be installed and the already installed steel mesh, with the distance between two adjacent support components not exceeding 3m.

[0012] Furthermore, the steel mesh connecting sleeve includes a locking plate, and the upper and lower sides of the locking plate are provided with conical sleeves. The steel bar is inserted into both ends of the locking plate, and the two conical sleeves are axially pressed together to make the locking plate clamp the steel bar inward.

[0013] Furthermore, the connecting assembly includes a screw, on which a washer and a nut are disposed.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This invention provides a support and positioning device suitable for vertical modular steel mesh. Its structure is simple, it can be made from locally sourced materials, and its cost is low. Using back-clamp support rods as supports and filling the gaps between the back-clamp support rods with connecting plates improves the overall stability of the support structure, ensures the safety of construction personnel, and reduces the risk to operators. The gaps between the back-clamp support rods are adjusted using bolts, making it flexible for installing steel mesh of various diameters. Furthermore, when clamping the steel bars with the back-clamp support rods, the steel bars can be tightened by screws, providing reliable support for the vertical steel mesh and effectively improving construction efficiency and safety.

Detailed Implementation

[0023] like Figure 1-4 As shown, a temporary support device for vertical modular steel mesh includes a support assembly 4 and a steel mesh connecting sleeve 3. The support assembly 4 is obliquely disposed outside the installed steel mesh 2. The support assembly 4 includes two support rods, which clamp the steel mesh 1 to be installed and the installed steel mesh 2 and lock them in place by a connecting assembly 6. The steel mesh connecting sleeve 3 is disposed on the end of the steel bar of the installed steel mesh 2. The end of the steel bar of the steel mesh 1 to be installed is inserted vertically downward into the steel mesh connecting sleeve 3 and fixed by compression.

[0024] The two support rods are configured with a back buckle, and a gap is provided between the two support rods.

[0025] The support rod includes a first support rod body 41 and a second support rod body 42 connected vertically together; a gap is provided between the two second support rod bodies 42. Specifically, the support rod is made of standard angle steel, and the first support rod body 41 and the second support rod body 42 are the two sides of the angle steel, wherein the standard angle steel is L75×7 angle steel, and the two standard angle steel pieces are in a back-fastening form with a gap left in the middle.

[0026] Several connecting plates 5 are provided within the gap; the distance between two adjacent connecting plates 5 is no greater than 1m. Specifically, the connecting plate 5 is a steel plate, consisting of a 5mm thick steel plate and a varying number of 1mm steel plates to accommodate the gaps between standard angle steels, with a spacing of no more than 1m between each standard angle steel.

[0027] Using back-locked angle steel as support rods and filling the gaps between the back-locked angle steel with gusset plates 5 can improve the overall stability of the support structure, ensure the safety of construction workers, and reduce the risks to operators.

[0028] Several of the support components 4 are arranged along the length of the steel mesh to be installed 1 and the already installed steel mesh 2, and the distance between two adjacent support components 4 is no more than 3m.

[0029] The connecting sleeve 3 for the reinforcing mesh consists of two parts, an upper and an lower part, including a locking plate 32. Both the upper and lower sides of the locking plate 32 are provided with tapered sleeves 31. During installation, the reinforcing bar 7 is inserted into both ends of the locking plate 32, and the two tapered sleeves 31 are axially pressed together using a hydraulic crimping machine 8. This utilizes the tapered angle to clamp the reinforcing bar 7 inwards using the locking plate 32, thus completing the connection. After the reinforcing mesh 1 to be installed and the already installed reinforcing mesh 2 are initially connected through the connecting sleeve 3 and stabilized by the support assembly 4, the connecting sleeve 3 is pressed together using the hydraulic crimping machine 8 to fix the connection between the reinforcing mesh 1 to be installed and the already installed reinforcing mesh 2.

[0030] The connecting assembly 6 includes a screw 61, on which a washer 62 and a nut 63 are disposed. Specifically, the bolt 6 is an M10 bolt, wherein the screw 61 has a hexagonal head and a shank diameter of 10mm; the washer 62 is 2mm thick, with an outer diameter of 16mm and an inner diameter of 10.5mm; and the nut 63 is hexagonal, with a thickness of 6mm and an inner root diameter of 10mm.

[0031] Using bolts 6 to adjust the gap of the back-clamping angle steel can be flexibly applied to the installation of steel mesh with various diameters. In addition, when clamping the steel bars with the back-clamping angle steel, the bolts can also be used to tighten the steel bars, providing reliable support for the vertical steel mesh. This effectively improves construction efficiency and safety.

[0032] The working process of this utility model is as follows:

[0033] The pre-installed steel mesh 2 is embedded in the wall of the poured concrete; the steel mesh connecting sleeve 3 is pre-installed on the ends of the steel bars of the pre-installed steel mesh 2; the steel mesh 1 to be installed is hoisted to the installation area by a crane; the support component 4 adjusts the gap at both ends with bolts 6 to clamp the steel bars in the pre-installed steel mesh 2 on the other side and the steel mesh 1 to be installed on this side, and is tightened with the steel mesh 1 to be installed and the pre-installed steel mesh 2 by the screw 61 of the bolts 6, so that the steel mesh to be installed is kept vertical after being hoisted, and then the connecting sleeve 3 is squeezed to complete the fixing between the steel meshes; in order to improve the stability of the temporary support, a gusset plate is filled between the two angle steels of the temporary support; after all the steel meshes are connected, concrete is poured.

[0034] This invention improves the installation efficiency of steel mesh, ensures the mechanical properties of the structure itself, reduces the safety risks during the installation of steel mesh and subsequent concrete pouring, and enhances the safety and efficiency of the vertical modular steel mesh installation process. Compared with traditional methods, it saves time and reduces the safety risks for construction workers during the installation of steel mesh.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
