Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a novel external frame punching mesh fixing device. Background Art

[0002] In construction projects, the increasing number of novel architectural designs and diverse architectural shapes make facade protection increasingly difficult. Due to the height of some buildings and the high wind loads, conventional dense mesh safety nets and external scaffolding secured with wire ties are easily damaged by strong wind loads or human error, rendering them ineffective and posing a significant safety hazard.

[0003] The prior art (publication number: CN214423985U) discloses a connection device for fixing a perforated mesh on an external frame, which comprises a steel plate connecting piece (2), a bolt (3), a flat head steel pipe (4), a steel pipe fastener (5), a scaffolding longitudinal horizontal rod (6), a scaffolding inner vertical rod (7), a perforated mesh and a perforated mesh column (1), wherein the perforated mesh columns (1) are symmetrically fixed at both ends of the perforated mesh; a steel plate connecting piece (2) is provided at one end of the perforated mesh column (1) away from the perforated mesh, and the steel plate connecting piece (2) is welded and fixed to the perforated mesh column (1); a flat head steel pipe (4) is provided between two adjacent perforated meshes, and one end of the flat head steel pipe (4) is located between the two symmetrically arranged steel plate connecting pieces (2); a bolt (3) is provided on one side of the flat head steel pipe (4), and the bolt (3) is fixed on the other side of the flat head steel pipe (4). One end of the bolt (3) passes through two symmetrically arranged steel plate connecting pieces (2) and a flat-head steel pipe (4); one end of the bolt (3) is provided with a nut, and the bolt (3) is meshed and connected with the nut; scaffolding inner vertical poles (7) are equidistantly provided on one side of the punching mesh; a scaffolding longitudinal horizontal pole (6) is provided on one side of the punching mesh; a steel pipe fastener (5) is provided on one side of the scaffolding inner vertical pole (7); one end of the steel pipe fastener (5) is sleeved and fixed on the outside of the scaffolding inner vertical pole (7), and the other end of the steel pipe fastener (5) is sleeved and fixed on the scaffolding longitudinal horizontal pole (6); the end of the flat-head steel pipe (4) away from the punching mesh is provided below the corresponding scaffolding longitudinal horizontal pole (6), and the scaffolding longitudinal horizontal pole (6) is fixedly connected to the flat-head steel pipe (4) through the steel pipe fastener (5).

[0004] Although this device can realize the connection of the perforated mesh, it is necessary to construct a large number of devices when using it to realize the perforated mesh fixed connection system for multiple perforated meshes, which is inconvenient to install and disassemble. Utility Model Content

[0005] The purpose of the utility model is to provide a novel external frame punching mesh fixing device to solve the problems of low connection strength and inconvenient installation in the prior art.

[0006] To achieve the above purpose, the specific technical solution of a new type of external frame punching mesh fixing device of the utility model is as follows:

[0007] A novel external frame perforated mesh fixing device comprises two integrally arranged fixing plates and two T-shaped plates. The lower ends of the fixing plates are fixed to the upper ends of two perforated mesh outer frames via first bolts. The T-shaped plates are symmetrically arranged, forming a square shape. One end of a steel pipe is fixed between the T-shaped plates via a second bolt, and the other end of the steel pipe is fixed to the external legs. Through the cross-shaped design of the two parallel fixing plates and the T-shaped plates, the device effectively connects the perforated mesh to the external legs, forming a stable support structure and improving overall stability.

[0008] Furthermore, the T-shaped plate includes a vertically arranged straight steel plate and a zigzag plate disposed in the middle of the straight steel plate, with the opening of the zigzag plate being welded to the straight steel plate. By disposing the zigzag plate in the middle of the straight steel plate and welding it to the straight steel plate, a more robust structure is formed. This effectively increases the load-bearing capacity of the T-shaped plate, enabling it to withstand greater loads without deformation. The zigzag plate structure design reduces material usage while maintaining strength, thus reducing costs and overall weight, making transportation and installation easier.

[0009] Furthermore, the fixing plate comprises a main steel plate, with butt joints provided at the lower ends of both sides of the main steel plate, each of which has a first screw hole for securing with a first bolt. By providing butt joints at the lower ends of both sides of the main steel plate and securing with the first bolt, the structural stability of the entire fixing plate is enhanced, enabling the fixing plate to be more securely connected to other components, such as the perforated mesh outer frame or the outer leg, thereby improving the overall structure's resistance to wind pressure and earthquake resistance.

[0010] Furthermore, the second screw holes of the straight steel plate, T-shaped plate, and steel pipe are correspondingly arranged, and the straight steel plate, T-shaped plate, and steel pipe are fixed together by second bolts engaging with the second screw holes. By correspondingly arranging the second screw holes of the straight steel plate, T-shaped plate, and steel pipe, and fixing them with second bolts, the connection strength between the three can be significantly enhanced, effectively increasing the connection strength between the steel pipe and the T-shaped plate, and thus increasing the connection strength between the outrigger and the perforated mesh.

[0011] Furthermore, a gasket is provided between the first bolt and the docking plate. Under vibration or impact loads, the gasket can provide additional friction to help prevent relative movement between the first bolt and the docking plate, thereby reducing the risk of the bolt loosening due to vibration.

[0012] Furthermore, the steel pipe is a flat-head steel pipe. The shape of the flat-head steel pipe makes the installation process simpler and faster. Construction workers only need to align the flat-head steel pipe with the corresponding screw hole, insert the second bolt, and tighten it to complete the installation, greatly reducing installation time and labor intensity.

[0013] Furthermore, the first and second bolts are all of the same size and type. When replacement or repair is required, since all bolts are of the same size and type, only one tool is needed to complete all operations. This effectively simplifies the installation and maintenance process, saving time and labor costs.

[0014] The utility model provides a novel external frame punching mesh fixing device with the following advantages:

[0015] 1. Simple structure and easy operation: The materials of the device are all common building materials on the construction site. The design is simple and clear, and the connection method between the components is intuitive and easy to understand, so that construction workers can quickly master its use and improve construction efficiency.

[0016] 2. Easy to disassemble and assemble, and can be used repeatedly: The components of the device are connected by bolts. The perforated mesh is simple and quick to disassemble and assemble, and will not cause damage to the components. Therefore, it can be used repeatedly, which meets the requirements of green construction.

[0017] 3. Strong structural bearing capacity: Through the close combination of components such as steel plate connecting pieces, bolts and flat head steel pipes, a stable connection system is formed, which effectively prevents the perforated mesh from falling off during high-altitude operations, thereby greatly improving the safety of the construction site.

[0018] 4. Wide range of applications: The device is suitable for punching meshes of various specifications and sizes. By adjusting the size and shape of the components, it can flexibly adapt to different construction needs and has strong versatility and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
