Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a buckle, a centering bracket and an anchor cable structure. Background Art

[0002] Prestressed anchor cable refers to a cable-shaped bracket that uses prestressed method to anchor the anchor cable inside the rock mass, which is used to reinforce the slope. The anchor cable is anchored into the rock mass through the hole of the weak structural surface of the rock mass by the anchor head, connecting the sliding body with the stable rock layer, thereby changing the stress state of the slope rock mass and improving the integrity and strength of the unstable rock mass of the slope.

[0003] The construction process of prestressed anchor cables includes drilling, production of prestressed anchor cables, anchor cable installation, grouting, anchor installation, anchor cable tensioning, quality control measures, and safety and environmental protection measures. In the process of prestressed anchor cable production, multiple centering brackets (also known as isolation brackets, expansion rings, or support rings) are often used to fix multiple anchor cables in bundles at equal intervals.

[0004] The prior art discloses a novel anchor cable centering bracket, including an anchor cable fixing part, a grouting pipe bearing part arranged in the middle of the anchor cable fixing part, and a supporting part connected between the anchor cable fixing part and the grouting pipe bearing part, and a plurality of perforations are evenly spaced along the circumferential direction on the side of the fixing ring. When fixing the anchor cables, if the two anchor cables can be symmetrically fixed according to the position of the support, the fixing method is to use a tie wire to wrap around the first anchor cable, then pass it under the fixing ring, and then pass it up. When it comes to the second anchor cable, the tie wire is passed through the perforation again, and then passed up to tie the anchor cable and then passed down, and passed through the next perforation again. The tie wire repeats the binding process multiple times, and finally is wound multiple times to fix it. This process requires the tie wire to be passed in and out multiple times, which is inconvenient for the staff to fix the anchor cable. Utility Model Content

[0030] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0031] Example 1

[0032] This embodiment provides a buckle 10, such as Figure 1 As shown, it includes a connection structure 101 and a connection plate 102 .

[0033] In an optional embodiment, the connecting plate 102 can be made of corrosion-resistant metal such as stainless steel and alloy, which can improve the corrosion resistance of the connecting plate 102 and enhance the service life of the connecting plate 102. A receiving groove 103 is provided on the connecting plate 102. When the connecting plate 102 is connected to the outer wall of the anchor cable fixing member 201 of the isolation bracket, the anchor cable 30 can be clamped on the outer wall of the anchor cable fixing member 201 through the receiving groove 103 on the connecting plate 102.

[0034] In another optional embodiment, the connecting plate 102 can be made of materials such as rubber and polyethylene, which can improve the corrosion resistance of the connecting plate 102 and enhance the service life of the connecting plate 102. At the same time, the connecting plate 102 has a certain flexibility, so that when the connecting plate 102 is connected to the outer wall of the anchor cable fixing member 201 of the isolation bracket, the connecting plate 102 can be bent in a direction away from the anchor cable fixing member 201 of the isolation bracket to form a receiving groove 103 in the middle of the connecting plate 102, and the anchor cable 30 is clamped on the outer wall of the anchor cable fixing member 201 through the receiving groove 103 on the connecting plate 102. It is also possible to open a receiving groove 103 on the connecting plate 102, and clamp the anchor cable 30 on the outer wall of the anchor cable fixing member 201 through the receiving groove 103 on the connecting plate 102.

[0035] The connection structures 101 are disposed at both ends of the connection plate 102 . The connection structures 101 are disposed on the connection plate 102 by welding, screwing or integral molding.

[0036] In an optional embodiment, the connection structure 101 may be a structure composed of a threaded rod and a nut, wherein one end of the threaded rod is fixed on the connection plate 102. When the connection plate 102 needs to be connected to the outer wall of the anchor cable fixing member 201, the other end of the threaded rod is first passed through the through hole 202 on the anchor cable fixing member 201, and then the nut is screwed to the other end of the threaded rod, and the nut is abutted against the inner wall of the anchor cable fixing member 201. This achieves the purpose of connecting the connection plate 102 to the outer wall of the anchor cable fixing member 201.

[0037] In another optional embodiment, the connecting structure 101 can be a bolt, and a threaded hole is opened on the connecting plate 102. When the connecting plate 102 needs to be connected to the outer wall of the anchor fixing 201, one end of the bolt is first passed through the through hole 202 on the anchor fixing 201 from the inner wall of the anchor fixing 201 to the outer wall of the anchor fixing 201, and then one end of the bolt is screwed to the threaded hole on the connecting plate 102 to achieve the purpose of connecting the connecting plate 102 to the outer wall of the anchor fixing 201.

[0038] The connection structure 101 may also be a clamping piece that can be clamped into the through hole 202 on the anchor cable fixing piece 201 .

[0039] Through the above structure, when the anchor cable 30 needs to be fixed on the isolation bracket, it is only necessary to place the anchor cable 30 between the connecting plate 102 and the anchor cable fixing piece 201, and connect the connecting structure 101 to the through hole 202 on the anchor cable fixing piece 201, so that the connecting plate 102 can be connected to the anchor cable fixing piece 201, and the anchor cable 30 can be clamped between the connecting plate 102 and the anchor cable fixing piece 201. This reduces the workload of the staff for threading the tying wire back and forth, and facilitates the staff to connect the anchor cable 30 to the anchor cable fixing piece 201.

[0040] In order to further facilitate the staff to directly clamp the connection structure 101 into the through hole 202 on the anchor cable fixing member 201. In this embodiment, Figure 1 As shown, the connection structure 101 includes a connection column 1011 and an abutment sheet 1012. The connection column 1011 is connected to the connection plate 102 by welding, screwing or integral molding. One end of the abutment sheet 1012 is connected to the connection column 1011 by welding, screwing or integral molding, and extends in a direction close to the connection plate 102. The abutment sheet 1012 can be made of elastic materials such as rubber and stainless steel, so that when the connection structure 101 passes through the through hole 202 on the anchor cable fixing member 201, the outer wall of the abutment sheet 1012 can be compressed in a direction close to the connection column 1011, so as to facilitate the abutment sheet 1012 to pass through the through hole 202 on the anchor cable fixing member 201. At the same time, after the contact piece 1012 passes through the through hole 202 on the anchor cable fixing piece 201, the outer wall of the contact piece 1012 extends in a direction away from the connecting column 1011, so that the end of the contact piece 1012 close to the connecting plate 102 can contact the inner wall of the anchor cable fixing piece 201. Thus, it is convenient for the staff to clamp the connecting structure 101 into the through hole 202 on the anchor cable fixing piece 201, so as to connect the connecting plate 102 to the anchor cable fixing piece 201, and clamp the anchor cable 30 between the connecting plate 102 and the anchor cable fixing piece 201.

[0041] In order to facilitate the staff to pass the connecting structure 101 into the through hole 202 on the anchor cable fixing member 201. In this embodiment, Figure 1 As shown, from the end of the connecting column 1011 away from the connecting plate 102 toward the connecting plate 102, the contact piece 1012 gradually moves away from the connecting column 1011, so that the contact piece 1012 is obliquely connected to the connecting column 1011. With this structure, the contact piece 1012 forms a conical structure on the connecting column 1011, so that the end of the contact piece 1012 can easily enter the through hole 202 on the anchor cable fixing member 201 and pass through the through hole 202 on the anchor cable fixing member 201.

[0042] In order to further facilitate the staff to pass the connecting structure 101 into the through hole 202 on the anchor cable fixing member 201. In this embodiment, Figure 1 As shown, a first gap 104 is arranged between the abutting piece 1012 and the connecting column 1011; the first gap 104 is used to reserve a stroke for the abutting piece 1012 to approach the connecting column 1011. With this structure, when the staff inserts the abutting piece 1012 into the through hole 202 on the anchor cable fixing piece 201, the abutting piece 1012 can be bent toward the connecting column 1011 to reduce the size of the first gap 104 between the abutting piece 1012 and the connecting column 1011, thereby reducing the external size of the abutting piece 1012, so as to facilitate the abutting piece 1012 to pass through the through hole 202 on the anchor cable fixing piece 201. After the abutment sheet 1012 passes through the through hole 202 on the anchor cable fixing piece 201, the abutment sheet 1012 can be restored in the direction away from the connecting column 1011 to increase the size of the first gap 104 between the abutment sheet 1012 and the connecting column 1011, thereby increasing the external size of the abutment sheet 1012, so as to facilitate the abutment of one end of the abutment sheet 1012 close to the connecting plate 102 against the through hole 202 on the anchor cable fixing piece 201.

[0043] When the worker needs to remove the connecting plate from the anchor cable fixing part, the worker can first bend the end of the abutment sheet close to the connecting plate toward the connecting column, and then move the abutment sheet along the inner wall of the anchor cable fixing part toward the outer wall of the anchor cable fixing part and withdraw it from the through hole of the anchor cable fixing part.

[0044] In order to evenly distribute the bending degree of the abutment sheet toward the connecting column when the abutment sheet passes through the hole in the anchor cable fixing member. Figure 1 As shown, a plurality of the abutment sheets are evenly arranged around the circumference of the connecting column. With this structure, when the abutment sheet passes through the hole on the anchor cable fixing piece, each abutment sheet bends to a certain extent toward the connecting column, thereby achieving the purpose of dispersing the bending degree of the abutment sheet toward the connecting column.

[0045] In order to facilitate the abutment sheet to bend toward the connecting column when the abutment sheet passes through the hole in the anchor cable fixing member. Figure 1As shown, a second gap is arranged between two adjacent abutment pieces; the second gap is used for the travel of the two adjacent abutment pieces approaching each other. Through this structure, in the process of the abutment piece passing through the perforation on the anchor cable fixing piece, the two adjacent abutment pieces can approach each other to reduce the size of the second gap, thereby facilitating the abutment piece to bend in the direction close to the connecting column, so as to reduce the risk of interference caused by the abutment between the two adjacent abutment pieces. After the abutment piece passes through the perforation on the anchor cable fixing piece, the two adjacent abutment pieces move away from each other to increase the size of the second gap, thereby facilitating the abutment piece to bend in the direction away from the connecting column, so as to increase the external size of the abutment piece, thereby facilitating the abutment piece to bend in the direction away from the connecting column, so as to increase the external size of the abutment piece, thereby facilitating the abutment piece to abut against the perforation on the anchor cable fixing piece at one end close to the connecting plate.

[0047] This embodiment provides a centering bracket, such as Figure 2-Figure 3 As shown, it includes an anchor cable fixing part, the anchor cable fixing part is provided with perforations, and also includes a buckle as described in Example 1, and the connection structure of the buckle is connected to the perforations. A buckle is provided on the anchor cable fixing frame of the centering bracket, and the connection structure of the buckle can be connected to the perforations on the anchor cable fixing part to connect the connecting plate to the anchor cable fixing part, and the anchor cable is fixed through the receiving groove on the connecting plate. At the same time, the buckle is convenient for the staff to install and disassemble, so as to facilitate the staff to install / disassemble the anchor cable on the centering bracket, thereby improving the flexibility and convenience during the use of the centering bracket.

[0048] In order to reduce the resistance between the buckle and the inner wall of the anchor hole when the centering bracket carrying the anchor cable is inserted into the anchor hole. Figure 2 As shown, the anchor cable fixing piece is provided with a groove; the perforation is provided at the bottom of the groove; and the end of the connecting plate is adapted to fit into the groove. Through this structure, the area of ​​the connecting plate exposed outside the anchor cable fixing piece is reduced, so as to reduce the area and risk of the side wall of the connecting plate contacting the inner wall of the anchor hole during the process of inserting the centering bracket carrying the anchor cable into the anchor hole, thereby achieving the purpose of reducing the resistance between the buckle and the inner wall of the anchor hole, so as to facilitate the staff to insert the centering bracket carrying the anchor cable into the anchor hole.
