Description
Technical field
The invention belongs to the job practices of construction formwork, particularly the job practices of after-pouring band beam-slab template in the monolithic reinforced concrete structure.
Background technology
At present, in construction work, for the needs of function with solve the shrinkage strain of settlement difference between high-rise main body and podium, steel concrete and problem such as concrete thermal stresses, the ater-casting method has obtained using widely in construction work.
The traditional handicraft of after-pouring band beam-slab template construction is identical with common beam slab mold method, promptly adopts and shores reinforcing.The time whole beam-slab template (comprising the position, ater-casting) is installed in construction as a whole, concreting beam slab and maintenance then, concrete beam plate intensity to be built reaches form removal and requires the back form removal, supports both sides, ater-casting beam slab more again.It is discontinuous, untimely when both sides, ater-casting beam-slab template supports; inevitably there is little sedimentation and deformation in the upper frame system in the concreting process of ater-casting; the new-old concrete seam crossing is difficult to accomplish smooth unification; the phenomenon that occurs the spillage faulting of slab ends in the construction through regular meeting; promptly influenced the concrete architecture quality in ater-casting, caused on the impression undesirable again.Structure construction more and more tends to clear-water concrete now, do not do in addition to plaster and whitewash, so the quality of alter-pouring strips mould plate fabrication and installation will directly have influence on the inherent quality and the apparent mass of concrete work.Strengthen the quality managemant and the process modification of alter-pouring strips mould plate engineering, have great significance improving concrete workmanship.
Summary of the invention
Technical problem to be solved by this invention provides a kind of job practices of improved after-pouring band beam-slab template, and is simple to operate, and the concrete finished product rigidity and the intensity of constructing is good, resistance to overturning is strong, reduces engineering cost.
The job practices of after-pouring band beam-slab template of the present invention, it is characterized in that in turn including the following steps: the beam-slab template support is checked, set up to axis, the both sides, ater-casting install the template of width 800mm～1000mm and reinforcing bar is installed, this place template supports and alone becomes an individual system, concreting beam slab and maintenance, first concreting beam slab intensity and reach form removal after the form removal requirement, the template of both sides, ater-casting and support are not removed, the cleaning of constuction joint cutter hair is preserved moisture, and alter-pouring strips mould plate, inspection alter-pouring strips mould plate epithelium absolute altitude and planeness are installed and connect solid with adjacent two side templates.
Major technique characteristics of the present invention are that ater-casting two side templates alone become an individual system when installing the beam slab of striding at place, ater-casting one, the both sides, ater-casting respectively install the wide beam-slab template of 800mm～1000mm, this independent system is not removed when removing beam-slab template, when installing alter-pouring strips mould plate, connect alter-pouring strips mould plate and both sides, ater-casting adjacent forms solid.Other process step is with the known technology mode.Both sides, ater-casting of the present invention are respectively stayed the wide template of 800mm～1000mm and are supported and do not remove, guaranteed the globality of both sides, ater-casting beam and slab structure, prevent from after the form removal untimelyly to cause that both sides, ater-casting beam slab is sagging (may to be caused beam slab face root cracking when serious, destroy because of shoring, influence the safety of total), secondly owing to alter-pouring strips mould plate and ater-casting two side templates are connected when installing alter-pouring strips mould plate and consolidate, guaranteed the apparent mass of concrete seam concrete cast-in-situ effectively, especially to clear-water concrete.Because the inventive method need not be torn an alter-pouring strips mould plate support system repeatedly open, has saved a large amount of labours in construction, has accelerated speed of application.
Braced structures of the present invention and support technology require with the known technology mode, generally are made up of stull, upright support and gripper shoe.The template of both sides, ater-casting 800mm～1000mm and support system are with layer beam-slab template and installing, and spacing is definite according to design.When removing beam-slab template, a top and the template of both sides, ater-casting are not removed, and before the construction of ater-casting, alter-pouring strips mould plate installs with its assembly unit tight, and planeness≤2mm at the bottom of the plate is with concreting difference of height≤2mm.
The present invention is simple to operate, and rigidity and intensity are better, resistance to overturning is stronger, installs and reinforces simply, and concrete finished product surfacing, the verticality of constructing are guaranteed, need not plaster leveling, can direct spread coated paint.This method has been saved the man power and material, has reduced the consumption of labour and machinery, has reduced engineering cost, and economic benefit and production efficiency are considerable.
