Description

Technical Field

[0001] The utility model belongs to the technical field of concrete lattice frames, and in particular relates to an anchoring structure of an assembled prefabricated concrete lattice frame for a highway slope protection. Background Art

[0002] In the current highway slope protection technology, the common practice is to use assembled prefabricated concrete grid structures to stabilize the slopes. These prefabricated concrete grids are usually prefabricated in factories and transported to the construction site for assembly. The assembly process mainly relies on construction workers to anchor with steel bars on site. Although this method can achieve slope stability to a certain extent, it has the problems of low construction efficiency and high cost.

[0003] Publication No. "CN207079606U" discloses an anchoring structure of a prefabricated concrete lattice frame for highway slope protection, in which an anchoring grouting steel flower pipe is inserted into a perforation of the anchoring grouting steel flower pipe, grouting is injected, and a firm connection is made; the construction period of the highway slope protection can be shortened, and the one-time rapid formation of the highway slope protection under general conditions can be ensured, and the lattice design requirements and the required technical quality effects that need to be achieved after the highway slope protection under general conditions is formed can be easily achieved;

[0004] In actual use, the use of steel bar anchoring requires a lot of manpower and time for on-site installation, which increases the time and cost of construction. In addition, since there is no special locking structure designed between the prefabricated concrete grid frames, the connection between the concrete grid frames is simply achieved by pouring concrete. This connection method is less stable and has poor overall seismic resistance when encountering geological activities, especially minor earthquakes or soil displacements. In minor geological activities, this connection method lacking effective locking can easily lead to cracking of concrete at the joints, and even displacement of the entire grid structure, thereby affecting the overall stability of the slope, which not only increases the subsequent maintenance costs, but may also pose a threat to highway safety.

[0005] In order to solve the above problems, the present application proposes an anchoring structure of an assembled prefabricated concrete grid frame for highway slope protection. Utility Model Content

The splicing component is arranged between two adjacent concrete grid frame bodies and connected by the splicing component. The fastening component is arranged on the splicing component.

[0009] As a preferred anchoring structure of an assembled prefabricated concrete grid frame for highway slope protection of the utility model, the splicing assembly includes a splicing top plate, a sliding top plate, a clamping side plate and a fastening bolt.

[0016] 2. The fastening sleeve is symmetrically fixedly connected to the top of the sliding top plate, and the threaded head is threadedly connected to the inner wall of the fastening sleeve.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown,

[0026] An anchoring structure of an assembled prefabricated concrete lattice frame for a highway slope protection comprises a concrete lattice frame body 1 on which a convenient concrete lattice frame assembly mechanism 2 is arranged.

[0027] In this embodiment: Under normal circumstances, precast concrete grid frames are usually precast in factories and then transported to construction sites for assembly. The use of steel bar anchoring requires a lot of manpower and time for on-site installation, which increases construction time and cost. In addition, since there is no special locking structure designed between the precast concrete grid frames, the connection between the concrete grid frames is simply achieved by pouring concrete. When encountering geological activities, especially minor earthquakes or soil displacements, this connection method has poor stability at the connection and overall seismic resistance. In minor geological activities, this connection method lacking effective locking can easily lead to cracking of concrete at the joints, and even displacement of the entire grid structure, thereby affecting the overall stability of the slope, which not only increases the subsequent maintenance costs, but may also pose a threat to the safety of the highway. By adding a convenient concrete grid frame assembly mechanism 2, the concrete grid frame can be assembled more efficiently, and the connection between adjacent concrete grid frames can be tighter and safer.

[0028] like Figure 1 - Figure 4 As shown,

[0029] Based on the anchoring structure of the existing prefabricated concrete lattice frame for highway slope protection, the concrete lattice frame can be snapped onto the pre-assembled base, thereby improving the assembly efficiency. Subsequently, the adjacent concrete lattice frames can be fastened and connected to ensure better stability between multiple concrete lattice frames.

[0030] More specifically:

[0031] In combination with the above content, in order to make the concrete grid frame more efficient during assembly, and the connection between adjacent concrete grid frames is tighter and safer, the concrete grid frame convenient assembly mechanism 2 includes an assembly base plate 21, a plug-in rod 22, a plug-in hole 23, a splicing component 24 and a fastening component 25. The plug-in rod 22 is fixedly connected to the top of the assembly base plate 21, and a plug-in hole 23 matching the plug-in rod 22 is provided at the bottom of the concrete grid frame body 1. A splicing component 24 is arranged between two adjacent concrete grid frame bodies 1, and they are connected through the splicing component 24, and the fastening component 25 is arranged on the splicing component 24.

[0035] Furthermore, if Figure 1 As shown, a guide groove 2411 for sliding the top plate 242 and the clamping side plate 243 is provided on the top of the spliced ​​top plate 241 , and a threaded hole matching the fastening bolt 244 is provided on the side wall of the concrete grid frame body 1 .
