Description

A cantilever scaffolding

Technical Field

The utility model belongs to the technical field of cantilever scaffolds, in particular to a cantilever scaffold.

Background technique

Cantilever scaffolding is a simple facility used in construction. It is divided into two types: one cantilever per floor and multiple cantilever. The gap between the bottom floor and the building must be closed and tightly protected to prevent falling objects. Cantilever scaffolding is a cantilever frame extending outward from the outer edge of the building structure as a construction superstructure or for exterior decoration. It must have sufficient strength, rigidity and stability, and can effectively transfer the load of the scaffolding to the building structure. Since cantilever scaffolding does not require the ground and a solid foundation as support for the scaffolding, and does not occupy the construction site, it has been widely promoted and applied.

In the Chinese utility model patent with the announcement number CN219672061U, a cantilever scaffold is disclosed. By setting a support mechanism, the bottom support assembly can be flexibly installed as needed, which is convenient for installation through the cooperation between the support rod and the top cable, so as to further support the cantilever end, and further ensure the stability of the overall support. At the same time, a suitable counterweight block can be installed by sliding on the rear side, which can ensure the tightness of the installation. Compared with directly increasing the weight by bundling stones, the overall installation can be more stable;

However, combined with actual construction experience, it is found that the cantilever scaffolding proposed in the above-mentioned comparative documents still has some defects: the positioning between the pressure plate and the I-beam is only achieved through extrusion and friction, and the positioning effect is poor. When the building scaffolding is installed and used, the huge thrust easily causes relative sliding between the I-beam and the pressure plate, which has poor stability and safety hazards. Moreover, when the I-beam is extended and adjusted, the support mechanism is fixed to the building facade and cannot be moved. Therefore, the support effect for the outermost end of the I-beam will be reduced and the support strength will be weakened. Therefore, it is urgent to improve the existing cantilever scaffolding and provide a cantilever scaffolding.

Utility Model Content

The purpose of the utility model is to provide a cantilever scaffold with reasonable design, simple structure, convenient and fast and stable installation, and good supporting effect, so as to solve the problems existing in the prior art.

The middle of the front and rear ends of the embedded part are rotatably connected with a threaded rod, and the outer sides of the two threaded rods that are close to each other are threadedly sleeved with movable blocks, and the inner walls of the front and rear ends of the embedded part are provided with storage grooves.

As a preferred embodiment, the movable block is snap-fitted and slidably connected in the receiving groove, and when the movable block is in an extended state, it can be snap-fitted and connected to the I-beam through the positioning groove.

As a preferred embodiment, the support assembly includes a first support rod, a second support rod and an adjustment sleeve, the outer movable sleeve of the first support rod is provided with the second support rod, the outer rotating sleeve of one end of the second support rod is provided with an adjustment sleeve, the outer surface of the first support rod is provided with a threaded structure, and the adjustment sleeve is threadedly connected to the first support rod.

In the solution of the utility model:

In the process of butting the I-beam with the embedded parts during hoisting, the limit column can squeeze the top inclined surface of the guide groove, so that the deep hole at the bottom of the I-beam and the limit column can be quickly aligned and butted. Then, the threaded rods at the front and rear ends of the embedded parts can be rotated to control the two movable blocks to slide stably toward the I-beam and engage in the positioning grooves provided on the side walls of the I-beam. Under the action of the movable blocks and the limit column, the I-beam can be stably and quickly positioned and installed, and its operation is stable and safe.

According to the actual installation and construction requirements, the overhanging length of the I-beam can be adjusted, and the adjusting sleeve can be rotated by using a large wrench or other tools, so that the first support rod threadedly connected to it can be controlled to slowly extend from the inside of the second support rod, thereby adjusting the overall length of the support assembly, making it convenient for the connecting plate to be close to the building facade and fixed with expansion bolts. The length-adjustable support assembly can always provide stable and strong support to the end of the I-beam during the extension of the I-beam. Compared with the comparative documents, this solution has a better supporting effect on the overhanging part of the I-beam, which is convenient for fully and effectively transferring the load to the building structure.

The counterweight block 5 is provided to improve the installation stability of the I-beam 1 , and the positioning bolts 6 are provided to fix the position of the counterweight block 5 .

On the basis of the above structure, the embedded component 7 includes an embedded part 71, a limiting column 72, a reserved groove 73, a threaded rod 74 and a movable block 75. The limiting column 72 is welded and fixed in the middle of the bottom end of the embedded part 71. A reserved groove 73 for placing the I-beam 1 is provided inside the embedded part 71. The longitudinal section of the reserved groove 73 is "Y"-shaped. The middle of the front and rear ends of the embedded part 71 are rotatably connected with threaded rods 74. The outer sides of the ends of the two threaded rods 74 that are close to each other are threadedly sleeved with movable blocks 75. The inner walls of the front and rear ends of the embedded part 71 are provided with receiving grooves 76.

The limiting column 72 can be engaged with the I-beam 1 through the deep hole 4, so as to preliminarily position the I-beam 1, and the arrangement of the threaded rod 74 can facilitate the control of the telescopic sliding of the movable block 75.

Before the I-beam 1 is fixedly installed, the embedded position of the embedded part 71 can be adjusted according to actual needs, and the overhanging length of the I-beam 1 can be adjusted. Then, a large wrench or other tool can be used to turn the adjusting sleeve 83 to rotate, and the first support rod 81 threadedly connected to the adjusting sleeve 83 can be controlled to slowly extend from the inside of the second support rod 82, so that the overall length of the support assembly 8 can be adjusted, so that the connecting plate 9 is close to the facade of the building and fixed with multiple expansion bolts 10. The length-adjustable support assembly 8 can always provide stable and strong support for the overhanging end of the I-beam 1 when the overhang of the I-beam 1 is adjusted. Compared with the comparative document, this scheme has a better supporting effect on the overhanging part of the I-beam 1, which is convenient for fully and effectively transferring the load to the building structure, and can make the cantilever scaffolding more stable and safer.
