Abstract
A late poured band construction method of basement soleplate belongs to the technical field of building construction, and is characterized in that a plain concrete cushion is poured and extended below a late poured band, a reinforced cushion as well as corresponding drainage ditches and dilatation joints are poured and installed above the plain concrete cushion; after the reinforcing steel bars of basement soleplate are finished to be bundled, one side of the late poured band is supported and poured with concrete, and the other side of the same basement soleplate is poured with concrete; the late poured band is cleaned and is poured with concrete so as to finally be sealed. The late poured band construction method of basement soleplate greatly reduces the operation capacity of chiseling off loosened concrete at both sides of the late poured band, thereby favourably guaranteeing the reliable connection between the basement soleplate and the reinforcing bar cushion, avoiding gaps between the basement soleplate and the reinforcing bar cushion due to shrinkage, effectively preventing groundwater from entering before the late poured band is sealed, and keeping dryness inside the basement; otherwise, the reinforcing steel bars under the basement soleplate are avoided to be buried by cement paste or sundries, thereby reducing the labor cleaning strength, and greatly improving the construction quality of late poured band.
Description
Technical field
The invention belongs to technical field of building construction, be specifically related to a kind of basement bottom plate rear pouring tape construction method.
Background technology
Since the reform and opening-up, especially since nearly ten years, Chinese society economy develops rapidly, and building size is grand day by day, it is complicated various that form of structure more becomes, and particularly overlength, super dark basement structure and high-rise main building are a lot of with the form of structure that low layer or multilayer annex are connected.In order to ensure the globality of structure and the impermeability of basement structure, design can be adopted the ater-casting form usually, as the provisional deformation joint of keeping somewhere in the cast-in-place whole reinforced concrete structure.Treat after sedimentation is basicly stable, with slightly expanded concrete the ater-casting to be sealed again in the agent structure completion certain hour, make structure form continuous integral body.By operation control, use rational, advanced construction technology, control ater-casting construction quality solves common quality defects such as crack, ater-casting, percolating water, is the important step of guaranteeing the overall structure quality.And at present basement bottom plate rear pouring tape construction method is kept away the problem that unavoidable basement bottom board hypodermis reinforcing bar is buried by cement paste or foreign material, time-consuming during cleaning, effort, and effect is bad, for construction quality has been brought influence.
Summary of the invention
At the above-mentioned problems in the prior art, the object of the invention is to provide a kind of technical scheme of basement bottom plate rear pouring tape construction method.
Described basement bottom plate rear pouring tape construction method is characterized in that may further comprise the steps:
1) plain concrete cushion layer is built in extension below the ater-casting;
2) the plain concrete cushion layer top is built arrangement of reinforcement bed course and corresponding blowdown ditch and shrinkage joint is set;
A. colligation arrangement of reinforcement bed course one side reinforcing bar is equipped with blowdown ditch and shrinkage joint in the middle of the arrangement of reinforcement bed course, and rubber fastening band is placed at the place, shrinkage joint, and blowdown ditch, shrinkage joint respective side are carried out formwork, builds this side arrangement of reinforcement bed course;
B. remove blowdown ditch, shrinkage joint one side template, in the shrinkage joint of rubber fastening band bottom, place plastic foamboard, colligation arrangement of reinforcement bed course opposite side reinforcing bar then, and blowdown ditch, top, shrinkage joint respective side carried out formwork, build this side arrangement of reinforcement bed course;
C. remove blowdown ditch, templates for expansion joints, and the shrinkage joint on rubber fastening band top watered connect;
3) colligation basement bottom board reinforcing bar;
4) ater-casting one side is carried out formwork, build basement bottom board one side concrete; Build basement bottom board opposite side concrete with quadrat method;
5) ater-casting is cleared up, treated that the project subject structure construction is finished, behind the settlement stability, build the ater-casting concrete, carry out the ater-casting sealing.
Described basement bottom plate rear pouring tape construction method is characterized in that in the step b) that top, shrinkage joint places plastic foamboard, replacing the formwork on top, shrinkage joint, the shrinkage joint on rubber fastening band top is watered connects thereby omit step c).
Described basement bottom plate rear pouring tape construction method is characterized in that template that ater-casting two avris described in the step 4) carry out formwork is cooperated by clad steel expanded metals and steel mesh reinforcement to constitute.
Described basement bottom plate rear pouring tape construction method is characterized in that arrangement of reinforcement bed course both sides reinforcing bar extends to basement bottom board, makes the basement bottom board of arrangement of reinforcement bed course and both sides form overall structure.
Described basement bottom plate rear pouring tape construction method is characterized in that described blowdown ditch two ends are equipped with sewage well.
Described basement bottom plate rear pouring tape construction method is characterized in that the described template inboard that is made of clad steel expanded metals and steel mesh reinforcement cooperation is equipped with the gummed lath.
Above-mentioned basement bottom plate rear pouring tape construction method has significantly reduced the workload of the loosening concrete chisel removals in both sides, ater-casting, help guaranteeing that basement bottom board reliably is connected with the arrangement of reinforcement bed course, avoid producing the slit because of shrinking between basement bottom board and the arrangement of reinforcement bed course, effectively stop ater-casting sealing phreatic entering before, keep the drying in the basement; Also avoided basement bottom board hypodermis reinforcing bar to be buried in addition, both reduced labor cleaning's intensity, improved the construction quality of ater-casting again greatly by cement paste or foreign material.
