Design, manufacturing and mounting method of combined splicing type upper-lower-layer bearing platform

Abstract

The invention discloses a design, manufacturing and mounting method of a combined splicing type upper-lower-layer bearing platform, and relates to the technical field of bearing platform construction.The design, manufacturing and mounting method comprises the following steps: S1, the manufacturing process of the bottom layer (prefabricated concrete blocks) of the bearing platform is that the peripheries of the prefabricated concrete blocks are folded into a shape through 3-mm steel plates (or 5-mm steel plates) and welded into a square or a rectangle, bottom-layer steel bar nets are welded after the square or rectangular square blocks are welded to be formed, and the intervals of the steel bar nets are made according to requirements in a building setting-up design drawing. According to the design, manufacturing and mounting method of the combined splicing type upper-lower-layer bearing platform, the bottom layer and the upper layer of the bearing platform and steel columns are mountedin batches, and finally subjected to combined splicing and mounting, thus all links of the bearing platform can be effectively and strictly controlled, the bottom layer of the bearing platform is combined by the four prefabricated concrete blocks, thus convenient transportation and demolition can be achieved, and through protection treatment at the heels of the steel columns, the overall stability of the bearing platform can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of bearing platform construction, in particular to a method for designing, manufacturing and installing a combined and spliced ​​upper and lower layer bearing platform. Background technique [0002] The cap refers to the reinforced concrete platform connected to the top of each pile set on the top of the pile foundation in order to bear and distribute the load transmitted by the pier body. The caps are generally used in industrial and civil buildings. The pile heads generally extend into the caps by 0.1 meters, and steel bars are anchored into the caps. Columns or piers are built on the caps to form a complete force transmission system. In recent years, due to the large diameter With the use of bored piles, the stiffness and strength of the piles are relatively large, so high pile caps have been widely used in bridge foundation engineering. [0003] In the process of installation, the existing caps mostly a...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a design, manufacture and installation method of combined splicing upper and lower decks, which solves the problem that the existing decks usually use integrated construction during the installation process, which affects the economic efficiency of the project. , safety and construction period have all caused a certain impact, and the construction is more difficult. There are no protective measures for the steel column during the installation process, which reduces the problem of the compressive performance of the cap.
