Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit caisson retaining reinforcement structure, and in particular to foundation pit caisson retaining reinforcement structure. Background Technology

[0002] The existing patent publication number (CN208363805U) discloses a protective fence for the edge of a foundation pit, belonging to the field of construction industry protection. It includes a frame with a mesh frame. One side of the frame has several insertion holes along its length. On the other side of the frame, parallel to the side with the insertion holes, several insertion rods are provided. Each insertion rod has an elastic bending piece on its wall, with the bent end of the elastic bending piece extending towards the frame. A vertical rod is provided on the frame, and a fixing element is provided at the ground end of the vertical rod for securing it to the ground. When the vertical rod is inserted into the ground and the insertion rod is inserted into the insertion hole, the elastic bending piece will lock onto the frame, thus connecting the two frames together. For disassembly, first remove the fixing element, then pull the vertical rod out of the ground. Use your hand to deform the elastic bending piece to fit tightly against the insertion rod wall. Then, remove the insertion rod along with the elastic bending piece from the insertion hole, thus achieving convenient disassembly and installation.

[0003] However, the connectors between its structures are elastic sheets, which lack strong connection stability. Furthermore, due to installation errors, the upper part of the enclosure may be uneven, and the gaps at the corners may be too large. After the entire ring-shaped closed enclosure structure is built, the interconnection strength at its upper part is not strong.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] The foundation pit caisson retaining reinforcement structure includes a telescopic handle with adjustable distance between its two ends. A locking structure is also provided on the telescopic handle to lock its working state. Clamping members with hinged joints are configured at both ends of the telescopic handle. These clamping members are fitted onto the upper part of the retaining structure. Bolts are provided on the clamping members; tightening the bolts fixes the clamping members to the retaining structure. The hinged joints allow the two fixed ends of the device to be clamped onto the retaining structure on the same plane or a plane with corners for reinforcement, effectively improving the overall connection stability of the upper part of the retaining structure and making it less loose.

[0006] Preferably, the telescopic handle includes a hollow square tube and two square inserts inserted into the hollow square tube, and also includes two second fastening bolts disposed at both ends of the hollow square tube, the second fastening bolts being tightened to clamp the square inserts.

[0007] Preferably, the telescopic handle includes a double-ended threaded sleeve and two screws. The two ends of the double-ended threaded sleeve are provided with threaded holes with opposite directions of rotation. The screws are threadedly connected to the threaded holes at both ends of the double-ended threaded sleeve to form a helical pair. When the double-ended threaded sleeve rotates clockwise, the screws move outward simultaneously under the action of the helical pair. Conversely, the screws move inward, thereby changing the actual working length of the telescopic handle.

[0008] Preferably, the clamping member includes a clamping kit and at least one first fastening bolt, the first fastening bolt being threadedly connected to the clamping kit, and the first fastening bolt being tightened to clamp the side of the enclosure structure, thereby fixing the clamping kit to the enclosure structure.

[0009] Preferably, the rotational stroke of the hinge joint is 360 degrees.

[0010] The advantages and positive effects of this utility model are:

[0011] It can effectively strengthen and align existing guardrail structures. It is not only simple and convenient to install, but also allows for adjustment of the installation angle. This provides good reinforcement for corners at different angles. By reinforcing the upper part of the corner, it effectively improves the overall strength and connection strength of the enclosure structure, making it more reliable than the original loose structure.
