Description

A sliding platform for installing high-altitude grid steel structure

technical field

The utility model relates to a sliding platform for installing high-altitude grid steel structures, which belongs to the technical field of high-altitude steel structure installation.

Background technique

Since the beginning of the 20th century, thousands of various types of steel grid structures have been built in many countries and regions of the world, providing more convenient and healthier spaces for human production and life, such as sports fields, hangars, various Theaters, various convention centers, etc. Grid structure is one of the forms of long-span space structure, which has good mechanical performance, greater rigidity and better integrity. In a sense, it is superior to plane structure and can effectively withstand various loads. , The structure is relatively convenient to manufacture and install. my country has created many simple and effective installation methods in the installation and construction of grid frames.

The mature and relatively simple grid installation techniques in China are as follows:

1. Mantanghong scaffolding roof assembly process: This process is to build scaffolding from the ground to the lower eaves of the roof, so that the roof forms a large platform, and the roof grid is assembled on the platform.

The advantages of this process: safety, less use of large hoisting machinery, fast assembly speed, and guaranteed quality. The disadvantage is that the workload of scaffolding is large, and the amount of scaffolding is large, which is not suitable for up and down cross construction.

2. Ground distribution pairing and aerial docking process: This process is to assemble the grids on the ground into a section of grids, and lift them into the air by two sets to carry out block pairing, and the grids are gradually advanced from one end to the other. .

The advantages of this process: save the use of scaffolding, occupy less construction space in the pavilion, and do not need large-tonnage lifting equipment. It can effectively solve the contradiction between roof construction scaffolding and ground stand civil construction. The disadvantages are: it takes a long time to occupy the two-step crane, and there are many high-altitude operations, which makes it difficult and dangerous to assemble in the air.

3. Small unit pairing on the ground, pairing process in the air: This method is to assemble only one ball and three rods on the ground, and then hang them in the air for assembly, which requires temporary pillars to cooperate with the installation.

The advantages of this process are: fast speed, no need for large-tonnage cranes, less space occupation, and can effectively solve the contradiction between roofing work and civil engineering construction at the same time. The disadvantage is: high-altitude operation, high risk.

The utility model is used to install the sliding platform of the high-altitude grid steel structure, and the further improvement lies in:

1. The sliding platform also has a truss girder arranged on the inside of the structural frame column. A sliding track is arranged on the trussing girder, and the pulley mechanism cooperates with the sliding track.

2. The pulley mechanism has a semi-I-shaped roller frame fixed below the end of the truss with the opening facing downward. The roller frame has a horizontal hole, and a roller shaft is inserted into the hole, and the roller shaft falls on the sliding track. Two pairs of adjustment positioning bolts are arranged on both sides of the roller frame, which are used to respectively bear against the sliding track from both sides to realize the adjustment of the angle between the truss and the sliding track and the positioning of the truss on the sliding track.

3. Above the truss, there is a supporting frame mounting seat corresponding to the ball node of the high-altitude grid along the longitudinal direction of the truss.

4. A pedal is laid above the truss.

The utility model is used for installing a sliding platform of a high-altitude grid steel structure, which has an ingenious structure, mechanical properties that meet actual needs, and reduces the risk of high-altitude operations. Using this sliding platform to install the high-altitude grid steel structure installation can effectively solve the difficulty that the grid span is large and the large-scale hoisting equipment on site is difficult to enter and install; during the construction of the roof grid, the lower civil work can be staggered; sliding assembly The support cost of the platform saves more than 40% compared with the high-altitude bulk method of full-house scaffolding; and it occupies less space around the building, only one side of the construction passage site is sufficient.
