Description

Technical Field

[0001] This utility model pertains to positioning devices in building construction, and in particular to a steel sheet pile positioning device. Background Technology

[0002] With the continuous development of modern construction, building materials are also being updated and developed at an increasingly rapid pace. Given the frequent occurrence of deep foundation pit construction, foundation pit support, as a crucial safety guarantee for deep foundation pit excavation, is receiving increasing attention. Steel sheet piles, as a material with strong structural adaptability, excellent mechanical properties, and high sustainability, are favored in many foundation pit support projects. However, the realization of these advantages highly depends on precise construction positioning, and traditional installation methods have become a bottleneck restricting their efficiency. Currently, the two existing traditional installation methods are manual alignment and support frame positioning. Manual alignment requires two workers to perform tasks such as manually aligning the locking joints, overlapping bolt holes, and tightening bolts, resulting in high labor costs, difficulty in synchronous coordination, and a high rate of locking joint misalignment due to vibration interference. Support frame positioning is limited by the fact that one support frame can only match a specific pit width, requiring multiple customized support systems for different projects, increasing construction costs. Therefore, we propose a steel sheet pile positioning device that is easy to disassemble, assemble, and transport, and allows for flexible adjustment of the limiting width, reducing the number of workers required. Utility Model Content

[0003] The purpose of this utility model is to provide a steel sheet pile positioning device with a reasonable structure that can solve the problems of low installation efficiency, low safety, inconvenient movement, limited application scenarios, and high labor costs of existing traditional installation methods. It is easy to disassemble, assemble, and transport, and the limiting width can be flexibly adjusted to reduce the labor intensity of workers.

[0004] The purpose of this utility model is achieved as follows: A steel sheet pile positioning device includes a steel sheet pile, two parallel and symmetrically arranged limiting channel steels, and corresponding installation holes on the opposite side walls of the limiting channel steels; the ends of a spacer steel pipe and a U-shaped spacer steel pipe pass through the installation holes on the two limiting channel steels respectively, and are limited and fixed by a steel pipe fixing device; steel wheels are provided at the bottom of both ends of the limiting channel steels, and the steel wheels are connected to a base welded to the bottom of the channel steel through a detachable bracket; a conical steel pipe penetrates the bottom of the limiting channel steel, and after the conical steel pipe is inserted into the ground, its depth is locked by a movable buckle to prevent the device from shifting during the pile driving process.

[0005] This utility model consists of a limiting channel steel, a spacer steel pipe, and a steel pipe fixing device. The conical steel pipe is movably connected to the limiting channel steel via a movable buckle to form a whole. A steel wheel base and a steel wheel with a detachable bracket are welded to the outer bottom of the limiting channel steel. The two types of spacer steel pipes pass through pre-drilled holes in the side wall of the limiting channel steel and are connected to form a whole via the steel pipe fixing device.

[0006] To facilitate workstation movement during maintenance, this invention incorporates steel wheels at the bottom of both ends of the limiting channel steel. The conical steel pipe can be stored within the channel steel using its structural features and the steel plate cross brace added to the middle of the channel steel. All four steel wheel bases at the bottom of the two channel steel sections are welded. The steel wheels are connected to their bases via a detachable bracket equipped with brake clips to allow the device to stop when not in operation.

[0007] To ensure that the sheet pile positioning device can meet the positioning requirements of different types of sheet piles, the connection depth between the spacer steel pipe and the U-shaped spacer steel pipe and the limiting channel steel can be adjusted to change the spacing of the limiting channel steel, thereby closely adhering to different types of sheet piles and flexibly adapting to various sheet pile construction positioning needs.

[0008] To prevent the continuous vibration during the sheet pile driving process from affecting the connection of the various components of the sheet pile positioning device, elastic pads are installed at the contact points between the steel pipe fixing device and the movable buckle and the channel steel. While leveling the working surface of the steel pipe fixing device and the movable buckle, these pads also effectively buffer the impact generated during construction, ensuring the stable connection of the fixing device components during construction.

[0009] To prevent the steel wheel from becoming stuck due to surface soil during use and thus hindering the movement of the device, the steel wheel support is designed to be detachable, allowing for easy disassembly and cleaning after the steel wheel is covered in soil.

[0010] To facilitate the overall installation of the device, taking advantage of the symmetrical structure of the channel steel, holes are made on both sides of the channel steel corresponding to the spaced steel pipes and U-shaped spaced steel pipes to facilitate rapid installation.

[0011] The cone-shaped steel pipe adopts a partially hollow structure, with the lower 1 / 3 being a solid steel pipe and the upper 2 / 3 being a hollow steel pipe. This satisfies the strength requirements of the cone section while reducing the overall weight of the device, reducing material costs, and facilitating transportation.

[0012] The spaced steel pipes, U-shaped spaced steel pipes, and cross bracing steel plates are thickened to improve the overall deformation resistance of the device and extend its service life. Beneficial effects

[0013] It saves labor costs; adopts a parallel inward extrusion action mode, which makes the force distribution reasonable; cross bracing is added to easily deformable positions to ensure quality; the structure is simple and has fewer parts, making installation and disassembly convenient; it adopts fixing and limiting devices to improve the adaptability of work in different scenarios; it is easy to move and convenient to transport.
