Abstract
The invention discloses an anti-water-seepage prefabricated slab construction method. The method comprises a prefabricated frame formed by enclosing prefabricated beams, and a prefabricated slab overlapped in the prefabricated frame, wherein a detachable loading mechanism for loading downwardly from the upper surface of the prefabricated slab is arranged on the middle part of the prefabricated slab; the fixing end of the loading mechanism is fixedly connected to the prefabricated beams; the load output end of the loading mechanism is pressed against the upper surface of the prefabricated slab; load is applied through the loading mechanism in order that the middle part of the prefabricated slab is deformed downwardly, and the circumference of the corresponding prefabricated slab is deformed towards the middle part of the prefabricated slab, so that pouring gaps are formed between the circumference of the prefabricated slab and corresponding prefabricated beams; micro-expansion concrete is poured into the pouring gaps, and the loading mechanism is removed after the cured micro-expansion concrete reaches certain strength, so that end cracking of the prefabricated slab is avoided.
Description
Technical field
The present invention relates to precoated plate construction technology field, be specifically related to a kind of precoated plate preventing plate end from seeping water
Construction method.
Background technology
The beam column component of conventional steel bar concrete framework house building is often after the formwork of building site
Casting concrete, its component connects reliable, globality and anti-seismic performance is good, but construction period is longer,
Complex management.And framework house building uses prefabrication and assembly construction mode to represent a kind of advanced developing direction.
Fabricated construction is because of the more feature of its piece, except stress problem to be solved, more to solve to use
In waterproof problem.Present waterproof type mainly has structural waterproof, and two kinds of forms of material waterproofing,
Material waterproofing substantially uses high molecular water-proof paint and coiled material to carry out.But due to working load, building base
Plinth sedimentation and deformation iso-stress effect, concrete and not ideal enough, the local ageing of waterproof material adhesive property etc.
Factor, plate end edge joint position once ftractures and occurs seepage reparation by cumbersome, and seepage usually becomes assembled
The common fault of building.
Based on this, it is necessary to research and develop a kind of novel precoated plate form of construction work, it is possible to prevent and reduce plate end
Crack produces, it is achieved structurally waterproof.
Summary of the invention
In order to make up the shortcoming that pre existing making sheet end easily seeps water, patent of the present invention provides a kind of water-impervious
Precoated plate construction method, utilizes precoated plate self-deformation at plate end Shi Hanzhang, thus reduces plate end check
