Embodiment 1

[0037] A method for strengthening an existing masonry wall by means of prefabricated concrete splicing and assembling. In this embodiment, the brick wall is strengthened on both sides by tension bolts, which includes the following steps:

[0038] Step 1: If Figure 1~3 As shown, before the double-sided reinforcement of the brick wall 4 between the upper floor 5 and the lower floor 6, firstly, the plaster layer on the surface of the brick wall components is removed to the base layer, the oil stains and laitance on the surface are removed, and the base layer is polished to a solid base ;The uneven parts should be polished or repaired; the surface dust should be removed, cleaned and painted with interface agent; Cracks are repaired;

[0039] Step 2: After preparing the adhesive according to the product specification, use a spatula to spread it on the surface of the treated base and the surface of the concrete prefabricated part 1 at the same time, with a thickness of 3mm; the co...

Embodiment 2

[0046] A method for reinforcing an existing masonry wall by means of prefabricated concrete splicing and assembling. In this embodiment, the brick wall is reinforced on both sides with S-shaped wall-through bars, which includes the following steps:

[0047] Step 1: If Figure 4~5 As shown, before the unilateral reinforcement of the brick wall 4 between the upper floor 5 and the lower floor 6, firstly remove the plaster layer on the surface of the component to the base layer, remove the oil stains and laitance on the surface, and polish it to a solid base layer; The uneven parts should be polished or repaired; the surface dust should be removed, cleaned and painted with interface agent; the plum blossom-shaped arrangement method should be used to set the drill-to-pull connection channel on the masonry; when there are cracks in the wall, the cracks should be repaired first. repair processing;

[0048] Step 2: After preparing the adhesive according to the product specification, ...

Abstract

The invention relates to the field of building construction and discloses a method for reinforcing an existing masonry wall by adopting a concrete prefabricating, splicing and assembling mode. The method comprises the following steps of firstly, treating a surface of a masonry, and drilling opposite-pulling connecting hole channels on the masonry by adopting a quincunx arrangement method; surfaces of a masonry base layer and a reinforced concrete prefabricated part are coated with an adhesive; a concrete prefabricated part is attached to the preset position of a surface of the base layer, and pressure is applied to a surface of the prefabricated part; after the used adhesive is solidified, a clamp is dismantled; lap joint treatment on horizontal distribution bars and vertical distribution bars reserved on the concrete prefabricated part is carried out; and grouting is conducted on the reserved hole channel, and meanwhile the anchoring connecting end is sealed. The method is advantaged in that a prefabricated part and an original brick wall are bonded into a whole through an adhesive and a prestress method, the static force and anti-seismic performance of the wall are improved, and an existing masonry structure has better bearing capacity and durability; only standard assembly is adopted in the construction process, on-site wet construction is greatly reduced, cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for reinforcing existing masonry walls by means of concrete prefabricated splicing and assembling. Background technique [0002] During the construction and use of the building, due to various problems such as unreasonable structural design, construction quality control level and management errors, natural disasters, and changes in use functions, the brick walls in the building need to be reinforced to meet the design or use requirements. Require. [0003] At present, the common reinforcement methods are: reinforced mesh cement mortar surface layer reinforcement method, reinforced concrete surface layer reinforcement method, outsourcing steel reinforcement method, external prestressed strut reinforcement method, carbon fiber composite material reinforcement method, etc. However, the reinforced mesh cement mortar surface layer reinforcement method and the reinforced ...
