Abstract
The invention provides a construction method for reserving water feed pipe grooves in a prefabricated shear wall. The method includes the following steps of firstly, manufacturing a trapezoid component (2); secondly, wrapping a layer of draft paper or plastic paper (1) on the outer side of the trapezoid component (2) for standby application; thirdly, placing a reinforcing steel bar framework (4) on a shear wall body (6) after the reinforcing steel bar framework (4) is manufactured, placing the trapezoid component (2) on the reinforcing steel bar framework (4), and then fixing the trapezoid component (2) to the reinforcing steel bar framework (4); fourthly, checking the trapezoid component (2) so that the trapezoid component (2) can not be covered with concrete after the concrete is poured on the shear wall body (6), wherein the upper side face of the trapezoid component (2) needs to be flush with the outer side face of shear wall body (6); fifthly, detaching the trapezoid component (2) after the shear wall body (6) is solidified and mold removal is conducted, wherein the trapezoid component (2) can be repeatedly used. By means of the method, material saving and environment protection are achieved, the pipe grooves and the shear wall body are formed through one-time pouring, the trapezoid component can be reused after being detached, and the construction method is suitable for the construction process of fabricated type building prefabricated shear wall components.
Description
Technical field
The present invention relates to a kind of construction method keeping for water pipe ditch on precast shear wall, be particularly useful for the construction method keeping for water pipe ditch on precast shear wall of the work progress of assembled architecture precast shear wall component.
Background technology
Along with the propelling of national architectural industrialization pace of construction, the construction of assembled architecture is carried out just in high gear, construction wall changes prefabrication shear wall into and site assembly by on-the-spot formwork pouring construction, the construction way that originally on-the-spot fluting installs feedwater piping on shear wall is inapplicable in Construction of Industrialization, also with industrialized building material-saving environmental and the theory that secondary is not dug disagree.It is pre-buried that current shear wall element precast factory can realize that hole reserves with sleeve pipe mostly, realize the reserved construction of shear wall side feedwater tube seat, still have suitable difficulty, the construction technology that also neither one is unified and technology way.
Summary of the invention
In order to overcome the technical barrier keeping for water pipe ditch in shear wall side, the invention provides a kind of construction method keeping for water pipe ditch on precast shear wall.The present invention can realize keeping for water pipe ditch in shear wall side in shear wall element precast factory, and can realize mould and reuse.
Specific embodiment of the invention scheme is: the present invention keeps for the construction method of water pipe ditch on precast shear wall, comprises the steps:
1) trapezoid part is made;
2) at outside bag one deck kraft or the plastic paper of trapezoid part, for subsequent use;
3) after treating that Making of reinforcement cage well, cage of reinforcement is placed on shear wall body, then trapezoid part is placed on reinforcement frame, then trapezoid part is fixed on reinforcement frame;
4), after shear wall body concreting, check that trapezoid part is not covered by concrete, and the upper side of trapezoid part need flush with the lateral surface of shear wall body;
5) to solidify and after form removal until shear wall body, dismounting trapezoid part, trapezoid part and reusable.
Precast shear wall of the present invention is kept for the construction method of water pipe ditch compared with prior art, tool has the following advantages:
1) the present invention can reserve at shear wall prefabricated units factory realization feedwater tube seat, can in prefabricated units factory and shear wall producing shaped.
2) the present invention saves material, the present invention is at the kraft of trapezoid part outer wrapping, can guarantee that trapezoid part disassembles (trapezoid part can not be clung by concrete) from shear wall smoothly, reuse after the trapezoid part dismounting used, effectively save timber consumption.And again can available protecting reinforcing bar, prevent the exposed corrosion of reinforcing bar.
3) environmental protection of the present invention, tube seat is that concreting is shaping, digs, can not produce building waste without the need to secondary.
The present invention can be implemented on shear wall prefabricated units and keeps for water pipe ditch, and trapezoid part can be realized reuse, tube seat smooth construction can be ensured, do not waste trapezoid part again, a kind of convenient and practical, energy-conserving and environment-protective precast shear wall on keep for the construction method of water pipe ditch.

Detailed description of the invention
The present invention keeps for the construction method of water pipe ditch on precast shear wall, comprises the steps:
1) make trapezoid part 2, the size of trapezoid part 2 is according to the caliber of pre-buried feedwater piping, more bigger than feedwater piping caliber, and the length of trapezoid part 2 is identical with the length of pre-buried pipeline;
2) at outside bag one deck kraft or the plastic paper 1 of trapezoid part 2, for subsequent use;
3) after treating that cage of reinforcement 4 is made, cage of reinforcement 4 is placed on shear wall body 6, then trapezoid part 2 is placed on reinforcement frame 4, then trapezoid part 2 is fixed on reinforcement frame 4; In the construction of shear wall component, shear wall body 6 is placed on ground line 3, ground line 3 is the finished surface of shear wall place floor, preprepared trapezoid part 2 is fixed in the side of the shear wall body 6 needing reserved tube seat, cage of reinforcement 4 is close in the minor face side of trapezoid part 2, the side, long limit of trapezoid part 2 flushes with the lateral surface of shear wall body 6, then by trapezoid part 2 and cage of reinforcement 4 fixation;
4) shear wall body 6 is by after injected hole 5 concreting, check that trapezoid part 2 is not covered by concrete, and the upper side of trapezoid part 2 (i.e. the side, long limit of trapezoid part 2) need flush with the lateral surface of shear wall body 6.
5) solidify after also form removal until shear wall body 6, dismounting trapezoid part 2, trapezoid part 2 is that is reusable.
In the present embodiment, above-mentioned trapezoid part 2 is wooden trapezoid parts.
The length of above-mentioned trapezoid part 2 is fixed by designing, and Fig. 1 gets 500mm, and the section size of trapezoid part 2 can adjust according to pipe diameter size, and generally burying wall pipe diameter is DN15 or DN20, can meet the demands by Fig. 1 institute dimensioning.The position of cage of reinforcement 4 on shear wall body 6 by design consideration buried pipeline need determine.
In the present embodiment, above-mentioned steps 3) with iron wire 7, trapezoid part 2 colligation is fixed on reinforcement frame 4.Above-mentioned iron wire 7 is thin wires.After treating shear wall body 6 depanning, cut off the iron wire 7 of fixing trapezoid part 2, then take out trapezoid part 2, namely reusable after this trapezoid part 2 is wrapped kraft or plastic paper.
