Problems solved by technology

[0002] Buckle-type scaffolding is a new type of scaffold widely used, with high bearing capacity, convenient disassembly and assembly, safety and stability, and is widely used in external scaffolding and formwork support frames. In actual construction, the length of the yin and yang corners of the cantilevered buckle scaffold is often related to the length of the specific engineering structure. At this time, the use of the traditional buckle scaffold will be greatly restricted.
[0003] The traditional buckle-type scaffolding has relatively high requirements on the accuracy of measurement and setting-out and the operation of workers when the I-beam on the cantilever layer is not equipped with a connecting beam. The cross-bar of the buckle-type scaffold with a slight error and a fixed length cannot be connected with the vertical pole. Connection, the construction is difficult; when there is a situation that the connection cannot be made, the steel pipe connection is often used on site instead, and the steel pipe does not meet the specification requirements, resulting in potential safety hazards; in order to reduce the construction difficulty, it can also be laid on the I-beam on the cantilever layer Two joint beams, but this scheme will consume a lot of I-beams, increase the construction cost, and cause unnecessary waste

Embodiment 1

[0042] This embodiment discloses a buckle type horizontal bar with adjustable length and a construction method positioning device, refer to figure 1 , including an intermediate pipe 1; two installation pipes 2 are respectively slidably socketed at both ends of the intermediate pipe 1, and the end of the installation pipe 2 away from the intermediate pipe 1 is the installation end connected with the scaffold pole; two fixed A core sleeve 3, one end is socketed with the intermediate pipe 1, and the other end is socketed with the installation pipe 2, so as to realize the coaxial socket between the intermediate pipe 1 and the installation pipe 2; and two fixing fasteners 4, which detachably fix the intermediate pipe 1 and the Two mounting tubes2.

[0043] refer to figure 2 , the fixing fastener 4 includes a small clamp 41 and a large clamp 42, and the small clamp 41 and the large clamp 42 are fixedly connected by a rigid member.

[0044] refer to image 3 , the inner hole of t...

Embodiment 2

[0056] The difference between this embodiment and embodiment 1 is that, referring to Figure 5 and Figure 6 , the inner diameter of the installation pipe 2 is greater than the outer diameter of the intermediate pipe 1, and the end of the installation pipe 2 away from the installation end is provided with an external thread that cooperates with the inner thread 33 of the centering sleeve 3, and the outer diameter of the intermediate pipe 1 is the same as that of the fixed pipe. The diameters of the small holes 31 of the centering sleeve 3 are the same, and the intermediate pipe 1 and the centering sleeve 3 have a gap fit; the outer circles of the two ends of the intermediate pipe 1 are equipped with detachable stoppers 6, and the limiters Position 6 allows the intermediate pipe 1 to slide in the installation pipe 2 and is restricted by the limiting surface 34 of the centering sleeve 3 to slide out of the installation pipe 2 .

Abstract

The invention relates to a length-adjustable disc buckle type cross rod and a construction method. The length-adjustable disc buckle type cross rod comprises a middle pipe; the two mounting pipes are slidably connected to the two ends of the middle pipe in a sleeving mode respectively, and the ends, away from the middle pipe, of the mounting pipes are mounting ends connected with a scaffold vertical rod; one end of each centering sleeve is sleeved with the middle pipe, and the other end of each centering sleeve is sleeved with the mounting pipe, so that the middle pipe and the mounting pipe are coaxially sleeved; the two fixing fasteners are used for detachably fixing the middle pipe and the two mounting pipes; according to the invention, stepless adjustment of the length of the cross rod of the ring-lock type scaffold is realized, the difficulty of site construction is effectively reduced, the application range and the erection efficiency of the ring-lock type scaffold are greatly improved, meanwhile, potential safety hazards caused by illegal erection of steel pipes are eliminated, erection of a coupling beam can be avoided, a large amount of I-shaped steel is saved, the construction efficiency is improved, and the construction cost is reduced. The economic benefit is obvious.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a coil-type cross bar with adjustable length and a construction method. Background technique [0002] Buckle-type scaffolding is a new type of scaffold widely used. It has high bearing capacity, convenient disassembly and assembly, safety and stability, and is widely used in external scaffolding and formwork support frames. However, the buckle-type scaffolding is produced according to a fixed module and has a fixed length In actual construction, the length of the yin and yang corners of the cantilevered buckle scaffold is often related to the length of the specific engineering structure. At this time, the use of the traditional buckle scaffold will be greatly restricted. [0003] In the case of the traditional buckle-type scaffolding without a joint beam on the I-beam on the cantilever layer, the requirements for measurement and setting-out accuracy and worker opera...
