Embodiment Construction
[0053] An assembled anti-seismic reinforcement structure of an existing masonry house, which is connected to the outside of the wall surface 1 of the original masonry structure, and includes wall panels 2, household panels 3, balcony panels 4 and external hanging panels corresponding to the original masonry structure. Plate 5, see for example figure 1As shown, the construction method for seismic reinforcement of prefabricated structures of existing masonry houses, the construction steps are as follows:
[0054] Step 1: Remove the external obstacles of the original masonry structure, carry out pre-renovation of the original underground pipelines that affect the new buildings before construction, and remove the illegal buildings (self-built small houses) of the residents.
[0055] Step 2, the first scaffold erection construction: connect the first scaffold with the original masonry structure, this scaffold is for the original balcony, air-conditioning board, overhanging eaves, g...

Abstract
A shock prevention and strengthening construction method for an existing brickwork dwelling house fabricated structure comprises the steps of demolishing barriers outside a building, constructing a scaffold for the first time, demolishing bulges on a wall surface, setting out, clearing the wall surface, embedding steel bars, demolishing the scaffold constructed for the first time, digging soil, performing spiral steel column construction, performing anchor stock construction, performing column supporting platform construction, performing the setting out of a foundation and the first layer of built-in fittings, embedding the foundation and the first layer of built-in fittings, mounting the first layer of household panel, mounting the first layer of balcony panel, mounting the first layer of cladding panel, back filling of the soil, constructing the scaffold for the second time, mounting the next layer of components, pouring and conserving on-site concrete layer by layer, joint grouting construction of a gap between each layer of wall panel and the wall surface of an original brickwork structure, performing roof construction, demolishing the scaffold for the second time and completing strengthening. The shock prevention and strengthening construction method solves the technical problems that an old brickwork dwelling house is poorer in anti-shock performance, external ornaments and internal components of the building are damaged, the living comfort is poorer, and energy consumption is great.
Description
technical field [0001] The invention relates to an anti-seismic reinforcement construction method of an existing masonry building. Background technique [0002] The anti-seismic and thermal insulation performance of old houses can no longer meet the requirements of modern people for the living environment. Due to the relatively backward construction technology in the past, most buildings have not undergone anti-seismic reinforcement and energy-saving renovations, and the anti-seismic performance is poor. The materials fall off, some components have been damaged, the living comfort is poor, and the energy consumption is large. Contents of the invention [0003] The purpose of the present invention is to provide an existing masonry house prefabricated structure seismic reinforcement construction method to solve the problem of poor seismic performance of old masonry houses, damage to building exteriors and internal components, poor living comfort, and low energy consumption. ...
