Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding erection, in particular to an auxiliary tool for building scaffolding erection. Background Technique

[0002] Scaffolding is a temporary working platform and support structure widely used in the fields of building construction, decoration, equipment installation, etc. It provides a safe working space for workers, facilitating high-altitude operations and the transportation and placement of materials. When erecting scaffolding, the parallelism requirement of the cross braces is crucial. The cross braces must maintain good parallelism to ensure the stability of the entire scaffolding structure and the balanced force. The parallel deviation between the cross braces should be controlled within a specified small range, which can effectively avoid problems such as uneven local stress and structural instability caused by non-parallel cross braces, thus ensuring the safety of construction workers and the smooth progress of construction.

[0003] However, currently when erecting scaffolding, most rely on the experience of workers, and a few use measurement methods to determine the installation position of the cross braces, but thus the parallelism of the cross braces cannot be guaranteed. Therefore, in view of the above phenomenon, an auxiliary tool for building scaffolding erection is proposed to meet the actual use needs. Content of the Utility Model

Detailed implementation mode

[0019] An embodiment is given by Figures 1-5 This utility model includes a centripetal bearing 1. An inner ring of the centripetal bearing 1 is fixedly sleeved with a mounting sleeve 2 that can be sleeved on the surface of a 48-mm steel pipe. An outer ring of the centripetal bearing 1 is fixedly sleeved with a positioning component 3. The positioning component 3 is symmetric left and right. Laser heads 4 are fixedly installed on both the left and right sides of the positioning component 3. A counterweight component 5 is arranged at the bottom of the positioning component 3;

[0020] The number of laser heads 4 is four. The four laser heads 4 are equally divided into two groups. The two groups of laser heads 4 are respectively located on the left and right sides of the positioning component 3. The height difference between a group of laser heads 4 is greater than 48 mm.

[0021] In this embodiment, after installing the first small crossbar or large crossbar on the vertical rod, the mounting sleeve 2 is sleeved on either one or both ends of the small crossbar or large crossbar. Then, by using the gravity of the counterweight component 5, the positioning component 3 is kept balanced, so that the laser heads 4 emit in the horizontal direction to form two parallel lines, that is, Figure 5 the laser lines 104 in

[0022] Thereby providing a reference auxiliary line when installing other crossbars, so as to ensure the parallelism of all small crossbars or large crossbars.

[0023] The positioning component 3 includes a mounting housing 31. Laser mounting grooves 32 for installing laser heads 4 are opened on both sides of the mounting housing 31. A battery compartment 33 for installing a battery is opened at the top of the mounting housing 31. A battery cover is movably installed at the top of the mounting housing 31. A sliding switch 34 for controlling the power switch of the laser heads 4 is arranged at the top of the battery cover. A bearing mounting groove 35 matching the centripetal bearing 1 is opened in the middle of the positioning component 3. A limiting protrusion 36 is integrally formed on the side surface of the bearing mounting groove 35.

[0025] In this embodiment, the positioning component 3 is symmetric and balanced on the left and right. After being installed on the installation support 37 and the installation housing 31, the outer ring of the centripetal bearing 1 can be fixed. By toggling the sliding switch 34, four laser heads 4 can be turned on simultaneously. After opening the battery cover, the battery in the battery compartment 33 can be replaced.
