The steel pipe support wall is connected to the structure by fasteners or welding, etc., which has low rigidity, poor stability, irregular installation, and high risk factor. Low recycling rate, section steel fixed buttress wall, inflexible size, bulky, inconvenient installation, serious waste of material cutting.

2) Limitations of traditional buttresses:

Steel pipe buttresses have great flexibility, poor stability, high risk factor, and are not suitable for high pier construction; section steel fixed buttresses have high cost, inconvenient construction, rigid dimensions, and serious waste of materials.

Contents of the invention

The object of the present invention is to provide a general-purpose assembled telescopic buttress wall for a coil-type climbing ladder, which can enhance the safety of personnel climbing up and down the ladder during high pier construction, and can be installed conveniently, reducing material waste and having a high recycling rate.

The object of the invention is achieved through the following technical solutions:

A universally assembled telescopic buttress wall for a coiled ladder, including several fixed frames surrounding the ladder and detachably fixed to the ladder, and several telescopic systems detachably connecting the fixed frames with the pier body; the telescopic system includes Remove the fixed wall-attached bars, and several sets of telescopic wall-attached bars that can be detachably connected to the wall-attached bars and the fixed frame. Each set of wall-attached bars is formed by two relative angles and connected with the attached wall bar. It is composed of telescopic wall-attached slanting rods in a triangular structure; the two ends of the wall-attached slanting rods are respectively hinged with the wall-attached horizontal rods and the fixed frame, and the wall-attached slanting rods are composed of two straight rods connected along the length of the straight rods. A plurality of bolt holes, the bolts pass through the corresponding bolt holes on the two straight rods to detachably fix the two.

As an option, the wall-attached crossbar is fixed to the pier body through a number of precision-rolled rebars penetrating into the pier body.

As an option, the fixed frame is composed of several rods that are detachably connected from end to end, and the fixed frame and the ladder are connected and fixed by anchor bolts.

As an option, the wall-attached cross bar and the fixed frame are fixed with a connecting piece, and the wall-attached slanting bar is detachably hinged to the connecting piece.

As a further option, the wall-attached slanting rod and the connecting piece are detachably hinged through bolts. In this scheme, the bolt not only connects the wall-attached slanting rod and the connecting piece, but also serves as a hinged rotating shaft.

The above-mentioned main scheme of the present invention and its further options can be freely combined to form multiple schemes, all of which are applicable and claimed in the present invention; can also be combined freely. After understanding the solution of the present invention, those skilled in the art can understand that there are various combinations based on the prior art and common knowledge, all of which are technical solutions to be protected by the present invention, and are not exhaustive here.

The working process is as follows: when the general assembled telescopic buttress wall of this application is constructed on a high pier, multiple buttress walls are set during the process of connecting the ladder to the height according to the height of the pier body and the slope ratio, so as to ensure the stability and safety of the ladder.

According to the slope ratio of the pier body, each buttress wall is stretched to a suitable position through the telescopic system to connect the pier body and the ladder as a whole. The fixed frame tightly surrounds the ladder, and the attached wall is reinforced layer by layer from bottom to top. After the reinforcement is completed, people can pass up and down.

The general assembly telescopic buttress is equipped with a telescopic system, which can adjust the installation difficulties caused by the slope of the structure. The standard parts are assembled and installed to reduce high-altitude welding and reduce the risk factor. The encircling ladder is consolidated, which increases the overall stability of the ladder. Rigidity ensures the safety of personnel passing.

Beneficial effects of the invention: it overcomes the disadvantages of poor stability and high risk factor of traditional steel pipe buttress walls; high cost, inconvenient construction, rigid size and serious waste of materials and other defects of section steel fixed buttress walls. The buttress wall of the present application is easy to operate, strong in versatility, high in stability and high in recycling rate.
