Description

Technical Field

[0001] The utility model relates to the technical field of assembled building installation tools, in particular to an assembled stair positioning and installation auxiliary tool. Background Art

[0002] Prefabricated buildings refer to building components that are standardized and factory-produced, and then transported to the construction site for assembly and construction. Each process can be installed on-site like equipment installation. PC stairs are one of the commonly used components in prefabricated buildings and are widely used in prefabricated buildings.

[0003] After the prefabricated staircase is transported to the construction site, it needs to be hoisted to the working floor by a tower crane and installed vertically from the top to the bottom. It pauses about 30 cm above the working floor. The construction workers use the stair slab to adjust the direction by hand, align the edge of the stair slab with the installation control line on the ladder beam, and then use tools such as crowbars and level rulers to assist in the installation. Since the installation of the staircase is divided into three steps: assembly, installation of fixed stair guardrails, and inspection, each step has its own special technical details. (1) Control the gap between the prefabricated staircase and the wall to ensure that the gap between the prefabricated staircase and the wall can be covered after the completion of the later decorative surface construction such as masonry painting, paint, and skirting, so as to achieve a beautiful effect; (2) Control the width of the shock-absorbing joint between the staircase and the ladder beam and the installation elevation of the staircase to ensure the height difference between the prefabricated staircase and the stair platform to meet the thickness of the stair platform construction method; ensure the spacing between the prefabricated staircase and the ladder beam to meet the shock-absorbing design requirements. Control the installation level and spacing size of the "scissor staircase" running up and down on the same stair platform to be uniform. (3) Control the docking efficiency between the prefabricated stairs and the embedded bolts, and level them once after installation.

[0004] In actual work, the installation and positioning of prefabricated stairs often leads to stair deviation due to non-standard on-site operations, the installation elevation cannot be effectively controlled, and the construction quality and safe operation cannot be guaranteed, resulting in a lot of manpower and economic costs for adjustments and improvements in the later stage. Summary of the invention

[0005] The utility model provides an auxiliary tool for positioning and installing an assembled staircase, and aims to solve the technical problems in the prior art of poor positioning accuracy, low installation efficiency and high safety risk of manual operation of the assembled staircase.

[0006] The utility model provides an assembled stair positioning and installation auxiliary tool comprising a positioning sleeve, a cross bar and a positioning device; the positioning device comprises a height positioning device and a horizontal positioning device; the height positioning device and the cross bar are located in the same plane and are arranged perpendicular to the cross bar; the horizontal positioning device is arranged at both ends of the cross bar; the positioning sleeve is fixedly connected to the lower surface of the cross bar.

[0007] Furthermore, the height positioning device includes a support rod, a height positioning joint and a width positioning joint; the support rod is fixedly connected to one side of the cross bar; the height positioning joint is arranged at one end of the support rod away from the cross bar; the width positioning joint is located at the bottom of the support rod and forms a right-angle limit groove with the height positioning joint.

[0008] Furthermore, the horizontal positioning device includes a telescopic joint and a limit piece; a limit groove matching the telescopic joint is opened in each of the two ends of the cross bar; one end of the telescopic joint extends into the limit groove and is slidably connected to the limit groove, and the limit piece passes through the cross bar and abuts against the telescopic joint.

[0009] Furthermore, a guide tube is vertically arranged on the upper surface of the cross bar, and the guide tube is coaxially arranged with the positioning sleeve.

[0010] Furthermore, the support rod is provided with a handle.

[0011] Furthermore, a level is provided on the crossbar.

[0012] Beneficial effects of the present invention:

[0013] The utility model provides an auxiliary tool for positioning and installing an assembled staircase, which is clamped with ladder beams and layer boards through pre-installed height positioning sections, width positioning sections and limit sections that meet the standard deviation. There is no need for workers to manually adjust the stairs for positioning, and one-time positioning can meet the horizontal position requirements and elevation requirements, thereby improving positioning accuracy and installation efficiency, and further reducing the installation risks of manual operations.

[0014] The utility model provides an auxiliary tool for positioning and installing an assembled staircase, which facilitates the docking of the staircase and the ladder beam by inertial sliding through a guide sleeve installed in the staircase and a guide rod arranged in the guide sleeve.

[0015] The utility model provides an auxiliary tool for positioning and installing an assembled staircase, which ensures the horizontality of the staircase during positioning and installation through a level meter. BRIEF DESCRIPTION OF THE DRAWINGS
