Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod reinforcement construction, in particular to a standardized anchor rod reinforcement positioning mold. Background Art

[0002] Anchor reinforcement construction is a technology used in geotechnical engineering to reinforce soil and improve slope stability. The key steps of anchor reinforcement construction include hole construction, rod body production and installation, grouting, waist beam construction, tensioning and locking. Among them, the types of anchor rod bodies include steel strand anchor rods and steel bar anchor rods. The processing of steel bar anchor rods includes welding and combining single or multiple steel bars.

[0003] The anchor reinforcement system usually includes multiple anchor main bars. Therefore, multiple anchor reinforcements need to be positioned during the construction process. The existing positioning method usually adopts the positioning reinforcement and the main reinforcement welding and fixing for positioning. In this process, it is usually necessary to set up an isolation frame and a positioning frame for positioning. In this way, the isolation frame and the main reinforcement need to be welded first at the construction site. After the main reinforcement and the isolation frame are welded, the positioning frame is welded on the outside of the reinforcement cage. In this positioning method, the anchor main reinforcement and the isolation frame are usually required to be fully welded. The welding amount is huge, which makes the construction speed slow, seriously affecting the construction progress, and it is very easy to produce deviations when welding the positioning reinforcement on the outside of the main reinforcement, and the positioning accuracy is not high. Utility Model Content

[0009] In one solution of the utility model: the mold main board is fixed to the anchor rod main reinforcement by welding.

[0010] In one solution of the utility model: two mold main boards form a group, and the two mold main boards are fixedly connected by a bracket.

[0011] In one solution of the utility model: the mold mainboard is fixed to the bracket by welding.

[0012] In one solution of the utility model: the bracket is connected to the corner position of the mold main board.

[0013] Beneficial effects of the utility model:

[0014] By setting the main reinforcement holes on the positioning mold, the steel bars and the mold can be quickly prepared to be closely combined, ensuring the positioning accuracy and construction efficiency of the anchor reinforcement cage system. At the same time, the standardized positioning mold can be factory-produced. It effectively solves the problems of large amount of anchor welding and complex construction procedures, has the advantages of green construction, low environmental impact, reduced construction procedures, improved labor production efficiency, etc., and has significant economic benefits.

[0015] When in use, two mold main boards are used as a group and fixedly connected by a bracket.

[0026] At present, the widely used anchor rod reinforcement positioning methods include setting up isolation frames and positioning frames. In the Hefei Garden Expo Park project, the anti-floating anchor rod adopts the setting of isolation frames + positioning frames. When using isolation frames, a steel bar is usually added between the main bars of the anchor rod, and connected to the main bars by welding. At the same time, in order to ensure the overall accurate positioning of the main bars in the drill hole, the positioning frame is used for positioning. During the processing and construction of the anchor rod, the welding work is complicated and the workload is large. Therefore, it is hoped that through research, a standardized anchor rod reinforcement positioning mold can be designed to achieve the purpose of reducing welding procedures and saving material use.

The mold main board 1 is provided with a plurality of steel bar holes 2, and the steel bar holes 2 match the anchor rod main reinforcement 3. The steel bar holes 2 are used to position the anchor rod main reinforcement 3, and the anchor rod main reinforcement 3 can be fixedly connected to the mold main board 1 by welding. A flexible sleeve 4 can also be set at the position of the steel bar hole 2, one end of the sleeve 4 is fixedly connected to the mold main board 1, and the size of the other end is smaller than the size of the end connected to the mold main board 1. The sleeve 4 can be made of elastic material, and the steel bar can be fixed by tightening, or the anchor rod main reinforcement 3 can be fixed by tying on the outside of the sleeve 4. The number of the steel bar holes 2 can be set according to actual construction needs. The shape of the mold main board 1 can be polygonal, and preferably, the mold main board 1 is an equilateral triangle. The size parameter of the mold main board 1 is customized according to the anchor rod size. For example, the side length is 139mm and the thickness is 8mm.

The bracket 5 can also ensure the center positioning of the anchor steel bar system. The bracket 5 can use steel bars with a diameter of 6.5 mm (as tie bars). It can be fixedly connected to the mold main board 1 by welding to ensure the connection strength. A card interface can also be provided on the mold main board 1 to connect the two by card connection. A positioning groove should be provided on the bracket 5 to play a positioning effect during connection. A protrusion structure can be provided on the inner side of the outer end of the card interface to prevent the bracket 5 from being carded into the card interface and coming out.

The third step is to drill holes in the triangular steel plate according to the predetermined perforation positions. The fourth step is to pass the anchor rod steel bar into the reserved hole of the triangular steel plate and place the triangular steel plate at the predetermined position. The fifth step is to fix the triangular steel plate and the anchor rod steel bar by (welding). The sixth step is to fix the positioning bracket 5 to the triangular steel plate by welding.
