Description

Technical Field

[0001] This utility model relates to the field of shotcrete and anchor support technology, specifically a shotcrete and anchor support structure for foundation pits. Background Technology

[0002] Reinforced concrete shotcrete support is one of the traditional support structures for building foundation pit slopes. The construction method generally involves first drilling holes in the excavated foundation pit slope according to the design parameters, then inserting anchor rods and grouting, then hanging the shotcrete support on the anchor rods exposed on the slope surface and binding them firmly with wire, and finally using professional shotcrete equipment to spray fine stone concrete onto the slope surface and the reinforcing mesh.

[0003] In actual use, the support mesh is usually laid directly on the slope of the foundation pit. Because the metal mesh is relatively large, it requires several workers to lay it together, resulting in a large workload. In addition, during the laying process, the size of the metal mesh is inevitably mismatched with the size of the foundation pit slope, and the metal mesh is often too large, requiring subsequent trimming, which causes inconvenience to the workers.

[0004] Therefore, we propose a shotcrete and anchor support structure for foundation pits to address the issues of large workload and subsequent trimming. Utility Model Content

[0007] Furthermore: the first connecting component includes a first connecting rod fixed to the side of the rectangular frame, and a connecting post is fixed to one side of the connecting rod, and the outer diameter of the connecting post is greater than the width of the connecting rod.

[0008] Furthermore: the second connecting component includes a second connecting rod fixed to the side of the rectangular frame, and a first mounting hole adapted to the connecting post is provided on one side of the second connecting rod, and the opening on one side of the first mounting hole is larger than the width of the connecting rod and smaller than the outer diameter of the connecting post.

[0009] Furthermore, the rectangular frame has chamfered corners at its corners; and a fixing component is installed between the four adjacent chamfers.

[0010] Furthermore: the fixing component includes a fixing seat installed between four adjacent chamfers, a pressure rod for cooperating with the chamfer is fixed on the side of the fixing seat, a second mounting hole is provided at the center of the fixing seat, and a fixing post is installed inside the second mounting hole.

[0011] Furthermore, a fixing opening adapted to the pressure bar is provided on one side of the chamfer.

[0012] The beneficial effects of this utility model are: This utility model, by setting up several support units, can select an appropriate number of support units according to the size of the foundation pit slope and assemble them, avoiding the situation where the assembled shotcrete support structure is too large, reducing the work of subsequent trimming by workers, reducing the workload of workers, and providing convenience for workers; in addition, during the assembly process of this support unit, a single worker can complete the assembly work without the help of other workers, thereby reducing the number of workers to operate and also reducing the workload of workers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] like Figure 1 As shown: A shotcrete and anchor support structure for foundation pits includes a shotcrete and anchor support structure assembled from several support units 1; by setting several support units 1, the size of the shotcrete and anchor support structure can be adjusted according to the size of the slope of the foundation pit, which has strong practicality; there is no need to trim long or large shotcrete and anchor support structures, thus providing convenience for workers; in addition, during the assembly of the support unit 1, the assembly work can be completed by a single worker, without being limited by the number of workers.

[0017] like Figure 2 As shown: In detail: Support unit 1 includes a rectangular frame 101. Several support plates 102 are fixed inside the rectangular frame 101 in a crisscross pattern. The support plates 102 reinforce the rectangular frame 101 and prevent deformation. An installation ring 103 is located at the center of the rectangular frame 101. It should be noted that the installation ring 103 is fixedly connected to the support plate 102 at the center, securing the installation ring 103 and preventing deformation during use. During use, one end of the anchor rod 4 passes through the installation ring 103 and is inserted into the slope of the pit. like Figure 2 and 3 As shown: The first connecting component 2 is installed on the left and top sides of the rectangular frame 101 respectively. In detail: the first connecting component 2 includes a first connecting rod 201, and a connecting post 202 is fixed on one side of the first connecting rod 201. It should be noted that the outer diameter of the connecting post 202 is larger than the width of the first connecting rod 201. like Figure 2 and 4 As shown: The right side and bottom side of the rectangular frame 101 are respectively equipped with a second connecting component 3. In detail: the second connecting component 3 includes a second connecting rod 301. A first mounting hole 302 is opened on one side of the second connecting rod 301. During use, the connecting post 202 can be inserted into the first mounting hole 302 to play a connecting role. It should be noted that: an opening is opened on one side of the mounting hole 302, and the width of the opening is greater than the width of the connecting rod 201 and less than the outer diameter of the connecting post 202, so that the connecting post 202 at one end of the first connecting rod 201 can be inserted into the first mounting hole 302 through the opening.

[0018] When two adjacent support units 1 are assembled, the adjacent first connecting component 2 and the second connecting component 3 cooperate to assemble the adjacent support units 1 together, thereby achieving the assembly function and preventing the adjacent support units 1 from falling off.

[0019] like Figure 2 and 5 As shown: It should be noted that each rectangular frame 101 has an inclined angle 104 at its corner. After several support units 1 are assembled, the same fixing component 5 can be installed between four adjacent inclined angles 104. By setting the fixing component 5, the assembled shotcrete support structure can be fixed on the slope of the foundation pit to prevent the shotcrete support unit from falling off during use and to improve stability. like Figure 5 As shown: In detail: The fixing component 5 includes a fixing seat 501 placed between four inclined angles 104. Each fixing seat 501 has an "L"-shaped pressure rod 502 fixed on its side. It should be noted that: a fixing opening 105 is opened on the inclined angle 104, and one end of the pressure rod 502 can be inserted into the inside of the fixing groove 105, thereby fastening the inclined angle 104; a second mounting hole 503 is opened at the center of the fixing seat 501, and one end of the fixing 504 passes through the second mounting hole 503 and is inserted into the slope of the foundation pit, thereby achieving the fixing function.

[0020] When using it, first select an appropriate number of support units 1 according to the size of the foundation pit slope and assemble them; If, during the assembly of support unit 1, several support units 1 are first assembled into a row, and then several rows of support units 1 are assembled together, a shotcrete and anchor support structure can ultimately be formed. When assembling several support units 1 into a row: insert the connecting post 202 on the side of one rectangular frame 1 into the first mounting hole 302 on the side of another rectangular frame 1; then repeat the operation in the same way as above, and finally a row of support units 1 can be assembled. When assembling several rows of support units 1: first, insert the connecting column 202 at the top of one row of rectangular frames 1 into the first mounting hole 302 at the bottom of another row of rectangular frames 1; then repeat the above operation to eventually form a shotcrete support structure.

[0021] After several support units 1 are assembled, the fixing seat 501 can be placed between four adjacent chamfers 104, so that several pressure rods 502 on the side of the fixing seat 501 can be inserted into the corresponding fixing holes 105, and then the fixing column 504 is used to pass through the second mounting hole 503 and fix it on the slope of the foundation pit.
