Pre-stress constraint concrete structure and manufacture method thereof

Abstract

The invention discloses a pre-stress constraint concrete structure and a manufacture method thereof. When the four categories of concrete structures of a concrete frame structure, a concrete frame-tube structure, a concrete frame-shear structure or a concrete truss-tube structure is manufactured, pre-stress ribs which are in parallel with axle lines of main beams are arranged in all main beams, thus each pre-stress rib is enabled to penetrate through all the main beams in the same axle line on the same plane, meanwhile constraint reinforced ribs are configured in the main beams, so that the main beams are enabled to form constraint beams, when the concrete strength of the poured main beams in a same layer reaches designed strength, the pre-stress ribs of all the main ribs in the same layer are subjected to tensioning and anchoring, the pre-stress ribs are all enabled to be in a tensioning state, the main beams on all different horizontal surfaces of the concrete structure are manufactured according to the method, and the pre-stress constraint concrete structure is manufactured and obtained. The pre-stress constraint concrete structure has the advantages of high bearing force in an overall structure, excellent rigidity, remarkable performance of seismic resistance, a small component cross section and lower constructional cost.

Description

technical field [0001] The invention relates to a prestressed restrained concrete structure for building and a manufacturing method thereof, belonging to the technical field of concrete building structures. Background technique [0002] Concrete structures such as concrete frame structure, concrete frame tube structure, concrete frame shear structure or concrete truss tube structure have been widely used in the construction field, but these concrete structures in the prior art generally have a large amount of steel consumption, and the concrete structure The main girder has the problems of large volume, large space occupation and high cost. In order to solve these problems, at present, in the prior art, prestress is applied to a single main girder in a concrete structure, and the bearing capacity of the main girder is increased and the height of the main girder is reduced by this method. Although this method improves the bearing capacity of a single beam and reduces the cro...

AI Technical Summary

Problems solved by technology

Although this method improves the bearing capacity of a single beam and reduces the cross-sectional height of the beam, it has little effect on improving the integrity of the entire concrete structure. The overall bearing capacity, overall rigidity, and overall seismic capacity of the concrete structure are still relatively poor.

Therefore, the use effect of the existing concrete structure is still not ideal.
