Description

Technical Field

[0001] This utility model relates to the field of composite support structure technology, and more specifically, to a prestressed recyclable anchor bolt and steel strip composite support structure. Background Technology

[0002] In terms of disassembly, traditional composite support structures use welding, which requires complex operations such as cutting during disassembly. This not only consumes time during disassembly but also easily damages components, making them unusable and resulting in a waste of resources. At the same time, due to the lack of specialized anti-loosening and separation structures, the components are tightly connected and there are no clear disassembly nodes, making them difficult to disassemble.

[0003] The existing publication number CN222782663U discloses a combined anchor cable, anchor bolt, and steel strip support structure for the roof of a metal mine stope. The four corners of the stope roof are supported by corner support groups, each consisting of anchor cables, steel strips, and anchor bolts. Several steel strips are arranged radially in a fan shape, with both ends fixed to the roof by anchor cables and the middle section fixed to the roof by anchor bolts. The middle section of the stope roof is supported by a central support group, which includes anchor cables, steel strips, and anchor bolts. The length of the steel strip is parallel to the short side of the stope, with both ends fixed to the roof by anchor cables and the middle section fixed to the stope roof by anchor bolts. This support structure can provide targeted support for different weak points; it supports the weakest points in the stope roof stability while saving support costs and improving support efficiency, featuring stable support and convenient construction. In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] Traditional composite support structures using welding often rely on welded connections between components during disassembly. For example, steel strips and anchor rods are often directly welded together. Disassembly requires cutting the connection points, which can easily damage components and prevent reuse. Furthermore, some existing composite support structures lack anti-loosening components, making them prone to loosening or misalignment during installation. This necessitates multiple checks and significantly extends construction time.

[0005] Therefore, a prestressed recyclable anchor bolt and steel strip composite support structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a prestressed recyclable anchor bolt and steel strip composite support structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prestressed recyclable anchor bolt and steel strip composite support structure, including a recycling mechanism and a steel strip assembly. The steel strip assembly is installed on the side of the recycling mechanism, and the recycling mechanism includes an anchor bolt assembly, an anchoring assembly, and an anchor assembly. An anchor assembly is installed on the outer diameter surface of the anchor bolt assembly, and an anchoring assembly is installed on the outer diameter surface of the anchor assembly.

[0008] Preferably, the steel strip assembly includes a horizontal steel plate, a vertical steel plate, and an anti-loosening component, and the vertical steel plate is installed below the horizontal steel plate, and the anti-loosening component is installed on the side of the vertical steel plate.

[0009] Preferably, the anti-loosening component includes a first anti-loosening washer, a second anti-loosening washer, and a fixing bolt, wherein the outer diameter surface of the fixing bolt is provided with the first anti-loosening washer, and the side of the first anti-loosening washer is provided with the second anti-loosening washer.

[0010] Preferably, the anchor bolt assembly includes a reinforcing bar, a reinforcing bar protective tube, and an anchor head, wherein the anchor head is installed on the side of the reinforcing bar, and the reinforcing bar protective tube is provided on the outer diameter surface of the reinforcing bar.

[0011] Preferably, the anchoring assembly includes an anchor body, a drilled hole, and a sealing end, wherein the outer diameter surface of the anchor body is provided with a drilled hole, and the side of the anchor body is provided with a sealing end.

[0012] Preferably, the anchor assembly includes an anchor, an anchor washer, and a rubber band, wherein the rubber band is installed on the outer diameter surface of the anchor, and the anchor washer is disposed on the outer diameter surface of the rubber band.

[0013] Preferably, the reinforcing bar is a cylindrical long rod, and the reinforcing bar and the anchor head are connected by welding, with their axes collinear, and the reinforcing bar protective tube is a cylindrical hollow tube.

[0014] Preferably, the anchor is annular in shape, and the rubber band is an annular elastic body. The rubber band is wrapped around the outer diameter surface of the anchor and tightly wraps the anchor.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, this prestressed recyclable anchor rod and steel strip composite support structure connects the horizontal and vertical steel plates in the steel strip assembly through an anti-loosening component. Only the fixing bolts need to be removed to separate the first and second anti-loosening washers, making it easy to separate the horizontal and vertical steel plates. In the anchor assembly, the anchor and anchor washer are interference fit, and the rubber band can be easily removed after loosening. The anchor assembly can be removed from the anchor rod assembly. The steel bar and steel bar protective tube in the anchor rod assembly are clearance fit and can be directly pulled out. Although the steel bar and anchor head are welded, the whole structure is lightweight and easy to recycle together. Only the sealing end of the anchor assembly needs to be removed. The anchor body does not need to be treated separately because it is bonded to the borehole wall.

[0017] 2. Compared with existing technologies, this prestressed recyclable anchor bolt and steel strip composite support structure, when installing the steel strip assembly, forms a C-shaped support structure by vertically assembling the horizontal and vertical steel plates, which is simple to position. The fixing bolts in the anti-loosening assembly pass through the vertical and horizontal steel plates in sequence to complete the connection, and the double gaskets can achieve the anti-loosening effect. In the anchor bolt assembly, the steel bar is a cylindrical long rod, and the steel bar protective tube is a cylindrical hollow tube. The two are fitted with a gap, and the sleeve process is smooth. The structure of the steel bar and the anchor head being welded in the same direction can ensure the axis alignment during installation and reduce adjustment time. In the anchor assembly, the anchor is a ring-shaped sleeve that can be directly sleeved on the outside of the steel bar. The rubber band, as a ring-shaped elastic body, can tightly wrap when wrapped around the outside of the anchor. The interference fit between the anchor and the anchor gasket can also quickly achieve fixation. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 4 The prestressed recyclable anchor bolt and steel strip composite support structure shown includes a recycling mechanism 1 and a steel strip assembly 2. The steel strip assembly 2 is installed on the side of the recycling mechanism 1. The recycling mechanism 1 includes an anchor bolt assembly 3, an anchoring assembly 4 and an anchor assembly 5. The anchor assembly 5 is installed on the outer diameter surface of the anchor bolt assembly 3, and the anchoring assembly 4 is installed on the outer diameter surface of the anchor assembly 5.

[0026] The overall support system is composed of a recovery mechanism 1 and a steel strip assembly 2. The steel strip assembly 2 is installed on the side of the recovery mechanism 1 to expand the stress range and disperse stress. The recovery mechanism 1 consists of an anchor bolt assembly 3, an anchoring assembly 4, and an anchor assemblies 5. The three are assembled in a hierarchical manner to achieve force transmission and locking. The anchor bolt assembly 3 serves as the basic component for applying prestress, and the anchor assemblies 5 are installed on its outer diameter surface. The anchor assemblies 5 are responsible for transmitting and locking the prestress generated by the anchor bolt assembly 3. The anchoring assembly 4 is installed on the outer diameter surface of the anchor assemblies 5, and the anchoring assembly 4 further transmits the force transmitted by the anchor assemblies 5 to the stable rock and soil mass. Through this structural cooperation, a complete force-bearing and support system is formed from the anchor bolt assembly 3 to the anchor assemblies 5, then to the anchoring assembly 4, and finally combined with the steel strip assembly 2, ensuring the stability of the support structure.

The outer diameter surface of the fixing bolt 11 is provided with the first anti-loosening washer 9, and the side of the first anti-loosening washer 9 is provided with the second anti-loosening washer 10. In the anti-loosening assembly 8, the fixing bolt 11 provides basic fastening force. The friction generated by the first anti-loosening washer 9 and the second anti-loosening washer 10 through their contact prevents the fixing bolt 11 from loosening. The double washer increases the anti-loosening effect and ensures the long-term stability of the connection between the vertical steel plate 7 and other components.

[0031] In a preferred embodiment, the anchor bolt assembly 3 includes a reinforcing bar 12, a reinforcing bar protective tube 13, and an anchor head 14. The anchor head 14 is installed on the side of the reinforcing bar 12, and the reinforcing bar protective tube 13 is provided on the outer diameter surface of the reinforcing bar 12. In the anchor bolt assembly 3, the reinforcing bar 12 serves as the core load-bearing component, transmitting tensile force through the anchor head 14. The reinforcing bar protective tube 13 is sleeved on the outside of the reinforcing bar 12, isolating the reinforcing bar 12 from the external environment, reducing corrosion and damage, and ensuring the mechanical properties of the reinforcing bar 12.

[0032] In a preferred embodiment, the anchoring assembly 4 includes an anchor body 15, a drilled hole 16, and a sealing end 17. The drilled hole 16 is provided on the outer diameter surface of the anchor body 15, and the sealing end 17 is provided on the side of the anchor body 15. The anchor body 15 in the anchoring assembly 4 is filled in the drilled hole 16. The tensile force of the anchor rod assembly 3 is transmitted to the stable rock and soil through the adhesion force with the hole wall of the drilled hole 16. The sealing end 17 seals the side of the anchor body 15 to prevent moisture and debris from entering and affecting the anchoring effect.

[0033] In a preferred embodiment, the anchor assembly 5 includes an anchor 18, an anchor washer 19, and a rubber band 20. The rubber band 20 is installed on the outer diameter surface of the anchor 18, and the anchor washer 19 is provided on the outer diameter surface of the rubber band 20. In the anchor assembly 5, the anchor 18 clamps the reinforcing bar 12 to lock the prestress, the rubber band 20 is wrapped around the anchor 18 to provide elastic preload, and the anchor washer 19 is placed on the outside of the rubber band 20 to fix the four sets of anchors 18. The anchor 18 and the anchor washer 19 are interference fit.

[0034] In a preferred embodiment, the reinforcing bar 12 is a cylindrical long rod, and the reinforcing bar 12 and the anchor head 14 are connected by welding, with their axes collinear. The reinforcing bar protective tube 13 is a cylindrical hollow tube.

[0035] In a preferred embodiment, the anchor 18 is in the shape of a ring sleeve, the rubber band 20 is a ring-shaped elastic body, the outer diameter surface of the anchor 18 is wrapped with the rubber band 20, and the rubber band 20 tightly wraps the anchor 18.

[0036] The working process of this utility model is as follows: First, when recycling the composite support, start with the steel strip assembly 2, disassemble the fixing bolts 11 in the anti-loosening assembly 8, separate the first anti-loosening washer 9 from the second anti-loosening washer 10, and then separate the horizontal steel plate 6 from the vertical steel plate 7. Then process the recycling mechanism 1, first loosen the interference fit between the anchor 18 and the anchor washer 19 in the anchor assembly 5, remove the rubber band 20 wrapped around the outer diameter surface of the anchor 18, and then remove the anchor assembly 5 from the outer diameter surface of the anchor rod assembly 3. Next, pull out the steel bar 12 and the steel bar protective tube 13 wrapped around it in the anchor rod assembly 3. Since the steel bar 12 and the anchor head 14 are connected by welding, they can be recycled together. After that, remove the sealing end 17 on the side of the anchor body 15 in the anchoring assembly 4. Since the anchor body 15 is bonded to the hole wall of the drill hole 16, it does not need to be recycled separately. Finally, the recycling mechanism 1 and the steel strip assembly 2 are recycled. The above is the working principle of the prestressed recyclable anchor rod and steel strip composite support structure.
