Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, specifically a leveling tool for rapid construction of prefabricated building staircases. Background Technology

[0002] In the field of prefabricated buildings, the accuracy of the secondary installation of precast concrete stairs directly affects the building quality and user experience. Traditional construction methods have many drawbacks in the positioning and leveling process. Before secondary installation, the base layer is often not thoroughly cleaned, and residual debris makes the stairs unstable. Positioning and layout rely on simple manual tools, which are inaccurate and prone to deviation. During installation, there is a lack of efficient and accurate leveling methods. Manual adjustment is not only inefficient but also makes it difficult to ensure the accuracy of the stairs' elevation and verticality, resulting in problems such as tilting and swaying after installation. To solve these problems, it is essential to develop a leveling tool for rapid construction of prefabricated building stairs. This tool can achieve rapid and accurate positioning and leveling of stairs, improving the overall installation quality.

[0003] Referring to the CN216109808U announcement, a positioning and leveling device for prefabricated walls includes a base. Inside the base is an adjusting component extending to its right side. Two rectangular boxes, symmetrically arranged on the top of the adjusting component, extend to the top of the base. Each rectangular box contains a positioning component extending to its opposite side. Two leveling components, symmetrically arranged vertically, are located on opposite sides of each positioning component. Each adjusting component includes a first partition. This positioning and leveling device for prefabricated walls offers the advantage of rapid positioning and leveling according to the size of the wall panels. It solves the problems of low positioning efficiency, complex and time-consuming manual positioning and leveling operations, and impact on construction schedules often encountered during the installation of prefabricated wall panels in traditional prefabricated wall panel construction. However, while this device can be effectively applied, it is generally not convenient for easy relocation of the entire device, resulting in some inconvenience during use and requiring further improvement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leveling fixture for rapid construction of prefabricated building stairs, comprising a base, with multiple electric push rods mounted on the center of the top of the base via a bracket, a top seat mounted on the top of the multiple electric push rods, a transmission body fixedly mounted on the center of the top of the top seat, a bidirectional lead screw rotatably mounted on the center of the inside of the transmission body, two nut seats threaded onto the outer wall of the bidirectional lead screw, a bearing seat fixedly mounted on the top of the nut seats, a placement plate provided above the bearing seat, and two bottom sides of the placement plate being provided with... The base has a side support frame, the bottom end of which is fixedly connected to the top end of the support base. Rollers are installed at the corners of the bottom end of the base. A connecting frame is fixedly installed on the bottom end of the base on one side of the rollers. A spiral cylinder is provided at the end of the connecting frame away from the base. A spiral rod is installed on the internal thread of the spiral cylinder. The top end of the spiral rod extends to the outside of the spiral cylinder and is equipped with a handle.

The output end of the microcontroller inside the control panel is electrically connected to the input end of the multi-section electric push rod.

[0006] Preferably, slide rails are fixedly installed on both sides of the top of the transmission body, and the top of the slide rails are slidably connected to the bottom of the support seat. A rocker arm is installed on the outer wall of one side of the transmission body, and one end of the rocker arm is connected to one end of the bidirectional lead screw. By rocking the rocker arm, the bidirectional lead screw is driven to rotate.

[0007] Preferably, a stabilizing frame is fitted on the outer wall of the lower end of the multi-section electric push rod. The bottom end of the stabilizing frame is connected to the top end of the base. The stabilizing frame is provided to limit and stabilize the lower end of the multi-section electric push rod.

[0008] Preferably, an adjusting plate is provided above the mounting plate, and a handle is rotatably mounted on one side of the bottom end of the adjusting plate. By rotating the handle, the threaded rod is driven to rotate.

[0009] Preferably, a threaded rod is fixedly installed at the center of the bottom end of the handle, the bottom end of the threaded rod extends through to the bottom of the placement plate, and the threaded rod is movably connected to the placement plate. By rotating the threaded rod, the distance between the placement plate and the adjusting plate can be adjusted.

[0010] Preferably, guide posts are movably connected inside the mounting plates on both sides of the threaded rod. The top end of the guide post is fixedly connected to the bottom end of the adjusting plate. The guide posts are used to limit the movement range of the adjusting plate.

[0012] (1) By turning the handle, the screw rod is driven to rotate inside the screw cylinder and slide upward, so that the screw rod drives the anti-slip foot seat to move upward. When the plane at the bottom of the anti-slip foot seat is higher than the plane at the bottom of the roller, several rollers contact the ground to push the leveling fixture as a whole to slide and transport, thereby achieving the purpose of easy and convenient transfer of the leveling fixture.

[0013] (2) By starting the multi-section electric push rod to extend and retract, the height of the adjusting plate is initially adjusted by the top seat. Then, the handle is rotated so that the handle is at the bottom of the adjusting plate and rotates, and the handle drives the threaded rod to rotate. At this time, the adjusting plate is raised and lowered above the placement plate, and the guide column is moved inside the placement plate to adjust the distance between the adjusting plate and the placement plate. The height of the adjusting plate can be adjusted a second time. Then, the stair plate is placed on the top of the two adjusting plates for construction and installation. The floor slab can be leveled and installed, thus ensuring the leveling effect of the floor slab when the leveling tool is used.

[0014] (3) By turning the crank, the double-acting screw is driven to rotate. At this time, the nut seat slides against the outer wall of the double-acting screw and drives the bearing seat to slide on the top of the slide rail. This allows the distance between the two leveling plates to be adjusted so as to perform horizontal adjustment and installation work on floor slabs of different lengths, thereby improving the applicability of the leveling fixture.

A handle 17 is rotatably installed on one side of the bottom end of the adjusting plate 12.

[0026] In use, the screw handle 17 is turned to drive the threaded rod 16 to rotate;

[0027] A threaded rod 16 is fixedly installed at the center of the bottom end of the handle 17. The bottom end of the threaded rod 16 extends through to the bottom of the mounting plate 14, and the threaded rod 16 is movably connected to the mounting plate 14.

[0028] In use, the distance between the mounting plate 14 and the adjusting plate 12 can be adjusted by rotating the threaded rod 16;

[0029] Guide posts 15 are movably connected inside the mounting plates 14 on both sides of the threaded rod 16, and the top of the guide posts 15 is fixedly connected to the bottom of the adjusting plate 12.

[0030] In use, the guide column 15 is set to limit the movement range of the adjustment plate 12;

[0031] Side supports 13 are provided on both sides of the bottom end of the mounting plate 14. The bottom end of the side supports 13 is fixedly connected to the top end of the bearing seat 8.
