Description

A modular assembly scaffolding system

technical field

The utility model belongs to the field of bridge foundation construction, and in particular relates to a scaffolding system suitable for the construction of bridge pier column scaffolding, which can be formed at one time, quickly assembled and disassembled, and can be used repeatedly.

Background technique

1) Traditional pier scaffolding:

Scaffolding is an important working platform and upper and lower passages for bridge structure foundation construction, especially pier column construction, and more and more are widely used. However, with the advancement of bridge construction towards scale and standardization, the current scaffolding construction There are certain limitations. At present, there are two types of pier body scaffolding construction, one is the traditional steel pipe fastener type scaffolding, according to the structural size of the pier column and the requirements of the scaffolding erection specification, the foundation of the scaffolding position is firmly treated, and the steel pipe is lowered by elastic wires on the foundation Place the vertical pole, sweeping pole, and horizontal pole in sequence, and fasten the vertical pole and the sweeping pole with fasteners, then install the large horizontal pole and small horizontal pole and fasten them with the vertical pole and large horizontal pole with fasteners respectively, and then Add temporary diagonal braces, attachment rods and scissors braces, etc., and finally lay scaffolding boards, bind protection and guard boards, hang safety nets, and so on, and gradually increase the scaffolding; Assembled scaffolding (wrist buckle or portal scaffolding), each unit component is transported to the site, and matched and installed according to the installation flow chart.

2) Limitations of the traditional structure:

The size of the first type of steel pipe fastener scaffold can be designed according to the form of the pier column, which has good versatility, but as a large-scale construction of pier columns, it needs to be installed and disassembled every time a concrete structure is constructed. Scaffolding boards and safety nets, etc.) have large material losses and low recycling rates, high manpower and equipment costs, and limited installation speed, low work efficiency, and high risks for workers working at heights. The second type of scaffolding that can be assembled (wrist buckle or portal scaffolding) is factory-processed into scaffolding sheet-like units, which can be quickly matched and installed on site. It has high efficiency and less maintenance, but its size and versatility are poor. The size of any form of pier body changes, and the one-time investment is relatively large (purchase or lease is higher than the first type of scaffolding). If the large-scale construction of pier columns is too expensive, it also needs to be installed every time a concrete structure is constructed. and disassembled once.

Utility model content

The purpose of this utility model is: to propose a modular assembly type scaffolding system, so that the scaffold can be quickly assembled and connected in the pier column of large-scale construction, and is suitable for the construction of various pier column scaffolding, with high versatility, and the components are not easy to lose.

As an option, scissor braces are also provided on the front and rear sides of the scaffolding module.

The foregoing main scheme of the utility model and its further selection schemes can be freely combined to form multiple schemes, which are all schemes that can be adopted and claimed in the utility model: as in the utility model, each selection can be combined with other selections arbitrarily, and the present invention After understanding the solution of the present invention, those skilled in the art can understand that there are many combinations according to the prior art and common knowledge, all of which are the technical solutions to be protected by the utility model, and are not exhaustive here.

Work process of the present utility model:

The shaped steel forms a rectangular frame, which constitutes the upper and lower surfaces of the cuboid structure of the scaffolding module. The vertical rods are directly welded into the shaped steel to form the side of the cuboid structure of the scaffolding module. The upper and lower sides of the scaffolding module form a rectangular structure composed of shaped steel, and the scaffolding module is more stressed. Reasonable, the overall stability is better, other large crossbars, small crossbars, and scissors are connected by fasteners, and the whole forms a three-dimensional rectangular grid structure; after the assembly of the scaffolding module is completed, the welding seam and the Check the fastener connection, and transport it to the construction position of the pier column after passing the test. According to the assembly drawing, the sub-modules will be installed and raised manually with a crane. The scaffolding modules and modules (mainly between the upper and lower modules and adjacent modules) pass short Scaffolding pipes and fasteners can be connected to adjacent scaffolding pipes.

Beneficial effects of the utility model: the modular assembly type scaffolding system is adopted, which overcomes the shortcomings of traditional scaffolding such as low installation efficiency, slow turnover speed, easy loss of components, poor versatility, poor force and integrity, and high risk of high-altitude operations. Using this scaffolding system, the on-site installation has high versatility, can be turned over many times, the components are basically not lost, the efficiency is high, the structural force is reasonable, the safety is high, the risk of working at heights is significantly reduced, and the overall cost of production and use is lower than that of traditional scaffolding. .
