Problems solved by technology

However, this kind of scheme is generally connected to the lattice column by bolts or flanges. Although the connection between the two can be achieved firmly, it is necessary to drill or assist the lattice column in advance to facilitate the bolt or flange connection.
It will cause processing damage to the structure of the lattice column. During the installation of the lattice column, it is necessary to connect the joint first. After the lattice column is installed in place, the joint should be disassembled. Inside, the work efficiency of the installation process is low

Embodiment Construction

[0030] In order to make the purpose and advantages of the present application clearer, the present application will be specifically described below in conjunction with the embodiments. It should be understood that the following words are only used to describe one or several specific implementation modes of the application, and do not strictly limit the scope of protection specifically requested in the application.

[0031]This embodiment takes the Yangzhou Jinghua City Center A1 and A2 projects as projects, with 2 to 4 floors underground and 8 floors above ground; the land area is about 72,000 m², and the total construction area is about 320,000 square meters. The foundation pit is rectangular, with a size of 189.65m×177m, and the excavation depth is about 18.6m. The foundation pit support is designed as two reinforced concrete circular inner supports, and the lower part of the inner supports is made of cast-in-place piles and steel lattice columns. The top elevation of the la...

Abstract

The invention belongs to the technical field of building construction, particularly relates to a device for installing a latticed column and a using method of the device. The device installing the latticed column and the using method of the device aim at solving the problems that when the latticed column serving as an inner support in a foundation pit support system is installed, due to the fact that the top elevation of the latticed column is below the ground, a guide column is arranged and connected to the latticed column through a connecting piece in the prior art, the installation requirement is controlled by using the guide column, the working efficiency is low, and the construction difficulty is high. According to the device, the movable joint guide column with the same structure as a lattice column unit is arranged, a connecting assembly is fixedly installed on the inner side of the lower end face of the movable joint guide column, one side of the connecting assembly extends out of the lower end face of the movable joint guide column to form an insertion type connecting part, and the movable joint guide column is inserted into the top end face of the latticed column through the connecting part and is connected to the latticed column into a whole. When the lattice column is subjected to a hoisting working procedure, the installation requirement of the lattice column is adjusted by adjusting the movable joint guide column, the device is simple in structure and convenient to operate, the construction efficiency is improved, and meanwhile materials are saved.

Description

technical field [0001] The application belongs to the technical field of building construction, and in particular relates to a device for installing a lattice column and a method for using the same. Background technique [0002] With the continuous development and application of construction science and technology, in order to meet the purpose of speeding up the construction progress and reducing the project cost, the reverse method construction has been applied more and more. In the construction of the underground building structure using the reverse method, the underground main structure and the foundation pit The enclosure system is combined. Before the formation of the column-slab system in the structure, the lattice column should be used as the vertical support. At the same time, the lattice column can also be used as the vertical support of the inner support in the foundation pit enclosure system. Therefore, the vertical support of the lattice column Degree, horizonta...
