Positioning method for reserved holes of pipelines of multi-storey building

Abstract

The invention provides a positioning method for reserved holes of pipelines of a multi-storey building, and relates to the technical field of building engineering. The specific construction method comprises the steps that the mounting positions of the vertical pipelines are determined on the upper surface of a floor slab on the bottommost layer of the building, and laser transmitting modules are arranged at the mounting positions; in the formwork erecting process of a floor slab on the second storey, laser receiving modules are fixed to reserved areas, and lasers are transmitted through the laser transmitting modules, so that the laser receiving modules generate position marks which conform to the mounting precision and are in the shapes of embedded sleeves of the reserved holes of the pipelines; the embedded sleeves are placed at the position marks, and the formwork erecting procedure of the floor slab on the second storey is completed; concrete is poured, formwork removal is conducted, and the reserved holes of the floor slab on the second storey are formed at the reserved sleeves; and the steps are repeated, and positioning and pouring of the reserved holes of the pipelines of all the storeys are completed. According to the positioning method, the problem that positioning of the reserved holes of the pipelines of the multi-storey or high-rise building is not accurate can be fundamentally solved, and the pipeline mounting related error and standard requirements can be met.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a positioning method for reserved holes in multi-layer building pipelines. Background technique [0002] At present, multi-layer or high-rise pipelines need to pass through multi-layer or high-rise floor slabs. The positioning of the pipeline installation position in the prior art is based on the edge of the formwork in the actual construction process of each floor, and the position measurement is carried out according to the size specified in the design. , measure the center position of the pipeline, and reserve a hole for pipeline installation by pre-burying the casing at the positioned center position. After the main body of the multi-layer or high-rise civil structure is completed, install it at the reserved hole. pipeline. [0003] However, due to the large size error of the actual concrete-formed floor slabs of the upper and lower floors, the minimum is ab...
