Foundation of assembly-decoration integrated building with light-weight steel structure, and construction method thereof

Abstract

The invention discloses a foundation of an assembly-decoration integrated building with a light-weight steel structure, and a construction method thereof. The construction method comprises the following steps: excavating a foundation pit through a spiral excavator, and arranging a foundation pit protection wall used for preventing soil mass inside and outside the foundation pit from sliding off is arranged in the foundation pit; arranging sectional steel ground beams on a sectional steel ground beam locator on the upper part of the foundation pit, adjusting the heights and the smoothness of the sectional steel ground beams by virtue of the sectional steel ground beam locator, and cushioning two cushion block supports on the lower part of each adjusted sectional steel ground beam; inserting the lower parts of sectional steel column feet in the foundation pit at first, and then connecting the upper parts of the sectional steel column feet with the sectional steel ground beams on the upper part of the foundation pit by virtue of high-strength bolts; carrying out pouring, vibration and maintenance for foundation concrete after the acceptance of assembly for the sectional steel column feet and the sectional steel ground beams; and removing the sectional steel ground beam locator and the cushion block supports after the maintenance for the foundation concrete is concluded, and then completing construction for the foundation of the building. The foundation and the construction method have the advantages of being low in excavation earth volume, capable of greatly reducing the workload of field construction, shortening a construction period and saving the labor cost, low in influence on the surrounding environment, and economic and environment-friendly.

Description

Technical field [0001] The invention relates to the field of construction technology, in particular to a foundation of a light steel structure assembly and decoration integrated building and a construction method thereof. Background technique [0002] The independent foundation construction steps of traditional light steel structure buildings are: [0003] 1. Clean up and level the construction land; 2. Lay out the lines according to the construction drawings and determine the location of the foundation; 3. Excavate foundation pits: At present, hook machines are generally used to excavate foundation pits. When digging foundation pits, apart from the foundation itself In addition to the occupied space, there are also considerations of preparing suitable working space for construction personnel. In addition, because it is difficult for the hook machine to excavate the foundation pit vertically from top to bottom in a small plane range, the traditional way of excavating the foundation...

AI Technical Summary

Problems solved by technology

In addition, due to the special environment of the construction site, it is inevitable that the backfill of the foundation pit will contain construction waste, which will adversely affect the original ecological environment of the construction site.

[0005] From the above construction steps of the independent foundation, it can be seen that according to the traditional method, the main problems in the construction of the independent foundation are: the workload of the construction is large, the construction period is long, There may be large errors in the positioning of the anchor bolts at the column foot
