Abstract
The invention discloses a underpinning and reinforcing method for a bearing wall for house reconstruction of a brick-concrete structure. The scheme adopts the reinforcement technology of additionally arranging the sandwich beam by underpinning the bearing wall modified by the brick-concrete structure house. The construction method of the underpinning beam comprises the following steps: the invention has the advantages of reducing the disturbance of the original structure, ensuring the construction safety, shortening the construction period, saving the support cost and the like, and creating great economic benefit and social benefit.
Description
Technical Field
The invention relates to a underpinning and reinforcing method for a transformed bearing wall of a brick-concrete structure house, in particular to a underpinning and reinforcing method for a transformed bearing wall of a brick-concrete structure house.
Background
The brick-concrete structure bearing wall underpins mainly adopt that when a wall body at the bearing wall part is firstly dismantled, a supporting device is required to be installed on a floor slab and a member; the method has the advantages of higher construction risk, larger disturbance to the original structure, higher relative ratio to the technical requirements, longer construction period, and great potential safety hazard in later-stage wall body use if the method is not implemented properly.
Disclosure of Invention
Technical problem to be solved
In order to solve the problems, the invention provides a underpinning and reinforcing method for a bearing wall for house reconstruction of a brick-concrete structure.
(II) technical scheme
The invention relates to a method for underpinning and reinforcing a bearing wall for house reconstruction with a brick-concrete structure,
1. a brick-concrete structure house reconstruction bearing wall underpinning and reinforcing method is characterized by comprising the following steps:
firstly, newly adding concrete beams and shoulder beams at the bottoms of two side plates of a bearing wall to be underpinned, and positioning and paying off.
And secondly, carrying out steel bar manufacturing and bar planting installation work.
And thirdly, erecting formworks on two sides of the wall body for reinforcement.
And fourthly, pouring by using grouting material and curing according to requirements.
And fifthly, removing the mold after the beam strength meets the design requirement.
And sixthly, dismantling the bearing wall.
Preferably, the concrete beam and the shoulder beam are additionally arranged at the bottoms of the two side plates of the bearing wall to form a sandwich member.
