A kind of accurate pre-buried water supply and drainage casing and construction method based on bim and aluminum alloy formwork

Abstract

Provided is a construction method for accurately embedding a water supply or water drainage casing pipe based on BIM and an aluminum alloy formwork. The construction method comprises the operation steps that 1, a model is built through the BIM technology, position collision checking of the water supply or water drainage casing pipe is conducted, and a water supply or water drainage casing pipe production drawing is deeply optimized and designed; 2, the aluminum alloy formwork of a floor or a wall or a beam where a pipeline passes through is designed through the BIM technology, and pipeline position information data are recorded and stored through a two-dimensional code; 3, the aluminum alloy formwork with a positioning clamp ring is produced according to the information model; 4, the aluminum alloy formwork of the floor or the wall or the beam is installed; and 5, concrete is poured into the floor or the wall or the beam, when the concrete strength meets the requirement, the aluminum alloy formwork is dismounted, and the water supply or water drainage casing pipe is accurately embedded in the concrete structure. The effect that pipelines on the floor are on the same straight line is ensured, and perpendicularity of later pipeline installation is ensured; pipelines on the beam or the wall can be on the same proper slope line, and gradient of later pipeline installation is ensured; and the pipelines can be installed at a time successfully, and rework caused by dimensional deviation is avoided.

Description

technical field [0001] The invention belongs to the technical field of building construction engineering, and in particular relates to a construction component and method suitable for standard floors of similar residential building engineering. Background technique [0002] In housing construction projects, water seepage in floor slabs and basement exterior walls has become a relatively common quality problem in construction projects, and it is difficult to repair and deal with. Most water seepage occurs in bathrooms, balconies and basement exterior walls, and more than 90% of water seepage in these areas is caused by pipes roots. [0003] The construction technicians and construction units of water supply and drainage projects are generally aware that the reserved casing of the pipeline cannot be constructed or constructed according to the drawings due to the deviation of the position and size of the pipeline, so that the hole has to be drilled twice, and some construction ...

AI Technical Summary

Problems solved by technology

[0008] (1). The position size is not easy to control, the error is large, and with the change and replacement of the formwork, the size must be measured again before each concrete pouring, which is not efficient, wastes the construction period, and is prone to errors;

[0009] (2). The reserved casing is easily disturbed or lost during concrete pouring construction;

[0010] (3). For floors with a large number of floors, it is not easy to reserve the upper and lower casings at the same position on a vertical line within an error range, resulting in that the pipe joints are not straight in order to be able to install and connect the pipes during pipe installation. Not sealed;

[0011] (4). Due to the inaccurate reservation of the casing, the floor often needs to be drilled twice, resulting in the destruction of the concrete structure
