Description

Technical Field

[0001] This utility model relates to the field of construction protection, and in particular to a detachable and modular isolation and protection device for adjacent camps. Background Technology

[0002] In the existing technology, in order to prevent construction vehicles, large machinery and construction materials from entering the construction clearance of the operating line, and to prevent construction personnel from accidentally entering the operating line, it is necessary to set up physical isolation and protection facilities on the existing line.

[0003] Currently, in most construction projects near operational railway lines, protective structures are mostly fixed by welding or temporary barriers. Traditional protective systems often suffer from difficulties in installation and dismantling, and are not easily reused, which not only increases construction costs but also affects construction efficiency. For example, Chinese utility model patent publication number CN215210544U discloses a protective device for the construction of a tram bridge spanning an existing highway line. Although its protective net is sliding, it is unstable in wind resistance after the protective nets on both sides are suspended, and the bottom of the protective net lacks stable support. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable and prefabricated adjacent camp isolation and protection device, which has the characteristics of quick installation and dismantling. Its base can achieve stable installation and dismantling, which is conducive to achieving a stable prefabricated structure. This makes the construction and dismantling of the protection system more convenient, greatly improves the construction efficiency near existing lines, and reduces construction time and cost.

[0005] To address the aforementioned issues, a detachable and modular adjacent camp isolation and protection device was adopted, comprising: Square steel tube uprights are installed at intervals along the direction of the concrete base slab, with their lower ends fixed to the concrete base slab and their upper ends fixed to the concrete beam. The horizontal steel tube crossbars are fixed to the horizontal steel tube uprights to form a vertical grid with the square steel tube uprights; Steel mesh, which is installed on the vertical mesh; T-shaped buckles are installed at intervals on the square steel tube crossbars. The flanges at their heads are adapted to the frame of the steel mesh, and the frame of the steel mesh is installed between the flanges and the square steel tube crossbars. U-shaped channel steel bases are set in pairs at intervals on the concrete base plate and extend into the square steel pipe uprights. The first bolt and nut assembly passes through the lower end of the square steel pipe upright and the U-shaped channel steel base, and is fastened to the lower end of the square steel pipe upright.

[0006] This structure, using T-shaped clips and the sides of the square steel pipe uprights to limit the vertical and horizontal movement of the steel mesh, facilitates its installation on the grid formed by the square steel pipe crossbars and uprights. Since the square steel pipe crossbars are narrower than the uprights, after installation, the side edges of the steel mesh will abut against the sides of the uprights. T-shaped clips are then installed on the upper and lower edges of the mesh to further tighten it, thus limiting its vertical movement. The lower end of the square steel pipe upright can be covered by the U-shaped channel steel base to prevent the base from being exposed. Finally, the first bolt and nut assembly is used for tightening, fixing the lower end of the square steel pipe upright to the U-shaped channel steel base, making installation and disassembly relatively convenient.

[0007] As a further improvement of this utility model, the square steel pipe upright is provided with spaced mounting holes for the square steel pipe crossbar to pass through, and an angle bracket is provided between the square steel pipe upright and the square steel pipe crossbar; the square steel pipe crossbar and the angle bracket are for the second bolt and nut assembly to pass through and be tightened.

[0008] With this structure, the corner brackets cross-fix the square steel tube uprights and crossbars, and the mounting holes allow the square steel tube crossbars to pass through, so that the corner brackets only need to be fixed to the square steel tube crossbars, which saves materials.

[0009] As a further improvement of this utility model, a transverse wall tie rod is provided on the concrete beam to fix the upper end of the square steel pipe upright.

[0010] With this structure, the upper end of the square steel tube upright can be fixed by welding or by bolts and nuts.

[0011] As a further improvement of this utility model, the web of the T-shaped buckle passes through the square steel tube crossbar, and the upper and lower surfaces of the square steel tube crossbar are provided with elongated holes perpendicular to its axis. The elongated holes and web of the square steel tube crossbar are used for the third bolt and nut assembly to pass through and tighten.

[0012] With this structure, the T-shaped buckle slides through the square steel tube crossbar and can be assembled and fixed by the third bolt and nut assembly. The elongated hole allows the third bolt and nut assembly to move when the web undergoes temperature deformation. Moreover, when the steel mesh is impacted, it can slip, providing frictional energy dissipation to prevent direct damage and facilitate subsequent maintenance.

[0013] As a further improvement of this utility model, a pad is provided between the third bolt and nut assembly and the square steel tube crossbar, and the pad is for the third bolt and nut assembly to pass through; a support plate is provided on the square steel tube crossbar opposite to and spaced apart from the pad, and a horizontal spring is provided on the support plate, and the spring abuts against the pad.

[0014] With this structure, the spring provides a reaction force, which can press the frame in advance before the third bolt and nut assembly is tightened, preventing gaps from remaining between the frame and the flange when the third bolt and nut assembly is tightened. As a further improvement of this utility model, a through hole is provided in the support plate, and a nut is fixed on the support plate and communicates with the through hole. The nut is set in the hollow part inside the spring. A half-threaded bolt is connected to the nut, and the bolt head of the half-threaded bolt extends between the spring and the pad.

[0015] With this structure, after the half-threaded bolt is tightened onto the nut, it limits the spring, thus not affecting the position of the pad or the connection between the third bolt and nut assembly and the T-shaped buckle. This makes it easy to install the frame first, then unlock the half-threaded bolt, the spring applies force to press the bolt head of the half-threaded bolt, pushes the pad, and drives the flange of the T-shaped buckle to press the frame, and then tighten the third bolt and nut assembly. This allows one person to press the steel mesh first and then assemble and secure it when installing.

[0016] The root of this utility model enables stable installation and disassembly, which is beneficial for achieving a stable assembled structure. Attached Figure Description

[0026] Example 1 like Figures 1-6 As shown, a detachable and modular adjacent camp isolation and protection device includes: Square steel pipe uprights 1 are arranged at intervals along the direction of concrete base slab 7, with their lower ends fixed to concrete base slab 7 and their upper ends fixed to concrete beam 8. The square steel tube crossbar 2 is horizontally and crosswise fixed to the square steel tube upright 1 to form a vertical grid with the square steel tube upright 1; Steel mesh 5, which is installed on the vertical mesh; T-shaped buckles 6 are installed at intervals on the square steel tube crossbar 2. The flange 601 at the head of the buckle is adapted to the frame 501 of the steel mesh 5. The frame of the steel mesh 5 is installed between the flange 601 and the square steel tube crossbar 2. U-shaped channel steel base 4 is set in pairs at intervals on concrete base 7 and extends into square steel pipe upright 1. The first bolt and nut assembly 3 passes through the lower end of the square steel pipe upright 1 and the U-shaped channel steel base 4, and is fastened to the lower end of the square steel pipe upright 1.

[0027] This structure, using T-shaped clips 6 and the sides of the square steel pipe uprights 1 to limit the vertical and horizontal movement of the steel mesh 5, facilitates the installation of the steel mesh 5 on the grid formed by the square steel pipe crossbars 2 and the square steel pipe uprights 1. Since the square steel pipe crossbars 2 are narrower than the square steel pipe uprights 1, after the steel mesh 5 is installed, the side frame 501 of the steel mesh 5 will abut against the side of the square steel pipe uprights 1. Then, by installing T-shaped clips 6 on the upper and lower frame 501 of the steel mesh 5 and pressing them together, the upper and lower parts of the steel mesh 5 are limited. The lower end of the square steel pipe uprights 1 can be covered on the U-shaped channel steel base 4 to prevent the U-shaped channel steel base 4 from being exposed. Finally, by tightening with the first bolt and nut assembly 3, the lower end of the square steel pipe uprights 1 and the U-shaped channel steel base 4 are fixed together, making installation and disassembly relatively convenient.

[0028] In this embodiment, the square steel pipe upright 1 is provided with mounting holes 101 at intervals for the square steel pipe crossbar 2 to pass through, and the square steel pipe upright 1 and the square steel pipe crossbar 2 are provided with corner brackets 9; the square steel pipe crossbar 2 and the corner brackets 9 are provided for the second bolt and nut assembly 11 to pass through and be tightened.

[0029] With this structure, the corner bracket 9 cross-fixes the square steel tube upright 1 and the square steel tube crossbar 2. The mounting hole 101 allows the square steel tube crossbar 2 to pass through, so that the corner bracket 9 only needs to be fixed to the square steel tube crossbar 2, which saves materials.

[0030] In this embodiment, a transverse wall tie rod 10 is installed on the concrete beam 8 to fix the upper end of the square steel pipe upright 1.

[0031] With this structure, the upper end of the square steel tube upright 1 can be fixed by welding or by bolts and nuts.

[0032] In this embodiment, the web 602 of the T-shaped buckle 6 passes through the square steel tube crossbar 2. The upper and lower surfaces of the square steel tube crossbar 2 are provided with elongated holes 201 perpendicular to its axial direction. The elongated holes 201 and the web 602 of the square steel tube crossbar 2 are used for the third bolt and nut assembly 12 to pass through and tighten.

[0033] With this structure, the T-shaped buckle 6 slides through the square steel tube crossbar 2 and can be assembled and fixed by the third bolt and nut assembly 12. The elongated hole 201 allows the third bolt and nut assembly 12 to move when the web plate 602 undergoes temperature deformation. Moreover, when the steel mesh 501 is impacted, it can slide, providing part friction energy dissipation, preventing direct damage and facilitating subsequent maintenance.

[0034] In this embodiment, a pad 13 is provided between the third bolt and nut assembly 12 and the square steel tube crossbar 2, and the pad 13 is for the third bolt and nut assembly 12 to pass through; a support plate 14 is provided on the square steel tube crossbar 2, which is opposite to and spaced apart from the pad 13, and a horizontal spring 15 is provided on the support plate 14, and the spring 15 abuts against the pad 13.

[0035] With this structure, the spring 15 provides a reaction force, which can press the frame 501 in advance before the third bolt and nut assembly 12 is tightened, so as to prevent there from being a gap between the frame 501 and the flange 601 when the third bolt and nut assembly 12 is tightened. In this embodiment, a through hole 16 is provided in the support plate 14, and a nut 17 is fixed on the support plate 14 and communicates with the through hole 16. The nut 17 is disposed in the hollow part inside the spring 15. A half-threaded bolt 18 is connected to the nut 17, and the bolt head of the half-threaded bolt 18 extends between the spring 15 and the pad 13.

[0036] With this structure, after the half-threaded bolt 18 is tightened onto the nut 17, it limits the spring 15, thus not affecting the position of the pad 13 or the connection between the third bolt and nut assembly 12 and the T-shaped buckle 6. This makes it convenient to install the frame 501 first, then unlock the half-threaded bolt 18, and the spring 15 applies force to press the bolt head of the half-threaded bolt 18, pushing the pad 13 and causing the flange 601 of the T-shaped buckle 6 to press the frame 501. Then, the third bolt and nut assembly 12 is tightened. This allows one person to press the steel mesh 5 tightly before assembling and securing it when installing it.

[0037] In this embodiment, the square steel pipe riser 1 is made of 100×100×4mm galvanized square pipe; the square steel pipe crossbar 2 is made of 60×60×3mm galvanized square pipe; all bolt and nut assemblies are made of M10 bolts; the U-shaped channel steel base 4 is made of C90×4mm U-shaped channel steel; the steel mesh 5 is made of 2m×1 unit-type protective mesh; and the T-shaped buckle 6 is made of 4mm thick T-shaped buckle.

[0038] The root of this utility model enables stable installation and disassembly, which is beneficial for achieving a stable assembled structure.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, with identical performance or use, should be considered within the protection scope of the present invention.
