Description
Technical field
The present invention relates to prefabricated panel package technique field, the reinforcing bar localization method installed particularly to a kind of precast wall body.
Background technology
" assembled room " is the popular address of assembled-type house, its full name is prefabricated dwelling house, it is to build house by the industrialized mode of production, it is that the part or all of component of house has been prefabricated in the factory, then transport is to job site, the house assembled by reliable connected mode by component and build up, is referred to as industrialization house or industrialized house in American-European and Japan.The difference in " assembled room ", simply part has carried out prefabricated, also the same with traditional architecture to pour to job site, difference is not seen in house from outward appearance at all after building up, compared with the house of traditional construction, component precision is higher, can improve the common quality defect such as wall crazing, seepage to greatest extent, and improve house safety integrity level, fire line and durability.It uses light partition wall system, and owner can change finishing as required.In view of above-mentioned advantage, assembled-type house is by large-scale popularization, but in the building course of assembled-type house, the vertical connection between its precast wall body relies on grout sleeve to connect, requiring that bottom reinforcement bars is corresponding with grout sleeve position, the position adjustment for bottom reinforcement bars becomes particularly important.
In prior art, the location of reinforcing bar typically uses limitting casing etc., intensity difference, and precision does not reaches requirement, the vertical connection not being suitable between precast wall body, when precast wall body is constructed, in the grout sleeve bottom the precast wall body of reinforcing bar upper strata to be inserted that bottom body of wall stretches out, conventional engineering find this position to stretch out reinforcement location inaccurate, construction speed and construction quality can be had a strong impact on；And existing limitting casing can not fix when pouring floorslab concrete, can only take off, it is impossible to avoid in casting process connecting, in prefabricated panel, the displacement that reinforcing bar causes.Therefore need badly at present and study a kind of the most convenient to operate but also that reinforcing bar positioning requirements can be met instrument.
Summary of the invention
Present invention aim at the reinforcing bar localization method providing a kind of precast wall body to install, solve existing reinforcing bar location general use limitting casing etc., not only intensity difference and precision do not reach requirements, be not suitable between precast wall body vertical connect, when precast wall body is constructed bottom the reinforcement location that stretches out of body of wall is inaccurate, can not fix when pouring floorslab concrete, can only take off, cannot be avoided the displacement in casting process caused the connection reinforcing bar in prefabricated panel, the technical barrier having a strong impact on construction speed and construction quality.
For reaching above-mentioned technical purpose, the present invention adopts the following technical scheme that:
A kind of steel bar positioning fixture installed for precast wall body, it is characterized in that: include the steel plate that the thickness of width and precast wall body adapts, have steel bar preassembling on described steel plate to box out, the diameter connecting reinforcing bar that the pore size that described steel bar preassembling is boxed out and precast wall body top are exposed adapts, the arrangement connecting reinforcing bar that the distribution that its steel bar preassembling is boxed out and precast wall body top are exposed adapts, for single or double；Steel bar preassembling in two ends of described steel plate box out correspondence upper face on be respectively welded internal diameter and steel bar preassembling and box out that adapt, vertical short steel sleeve, all short steel sleeves highly consistent.
As preferred technical scheme, having paired horizontal direction keyhole on the uniform height of the tube wall of short steel sleeve, keyhole interpolation has the latch for controlling to connect the insertion depth of reinforcing bar.
Further, described steel plate is the in-line steel plate for precast wall body stalk part reinforcing bar location or the L-shaped steel plate used around the corner.
Also it is welded with internal diameter and steel bar preassembling on the upper face of correspondence to box out that adapt, vertical short steel sleeve it is further preferred that the centrally located steel bar preassembling of described in-line steel plate or L-shaped steel plate is boxed out.
Further, the quantity of described short steel sleeve is 2～6.
It is further preferred that be also welded to connect ring box keel on the bottom surface of described steel plate.
Further, described frame keel are square steel keel or angle steel keel.
Further, the height of described short steel sleeve is 30～60mm, and described keyhole has 1～4 not waited right.
Additionally, the present invention relates to the use of the reinforcing bar localization method of the precast wall body installation that above-mentioned steel bar positioning fixture is carried out, it is characterised in that comprise the steps:
Step one, on superimposed sheet play reinforcement location control borrow line: after bottom precast wall body and superimposed sheet are respectively mounted and have adjusted, on superimposed sheet play reinforcement location control borrow line；
Step 2, installation steel bar positioning fixture: at end face, the corresponding connection reinforcement installation steel bar positioning fixture of precast wall body, the steel bar preassembling connected on reinforcing bar correspondence insertion fixture is boxed out interior；
Step 3, for the first time reinforcing bar position: according to the control line on superimposed sheet, carry out bar straightening and location；
Step 4, reinforcing bar binding and pour cast-in-place concrete layer: keep steel bar positioning fixture not take off, carry out reinforcing bar binding, after reinforcing bar binding completes, pour the cast-in-place concrete layer of top board；
Step 5, put on cast-in-place concrete layer reinforcing bar control borrow line: after the cast-in-place concrete layer of top board reaches upper people's intensity, again put on cast-in-place concrete layer reinforcing bar control borrow line；
Step 6, for the second time reinforcing bar position: control to borrow line according to the reinforcing bar on cast-in-place concrete layer, again re-start bar straightening and location；
Step 7, for the third time reinforcing bar position: after the cast-in-place concrete layer top board of top board reaches to lift intensity, carry out third time bar straightening and location；
Step 8, dismounting steel bar positioning fixture: before installing top layer precast wall body, eject corresponding control line at top board, unload steel bar positioning fixture, so far, the reinforcing bar location work that precast wall body is installed completes.
Wherein, in described step 2, steel bar positioning fixture includes being arranged on the in-line fixture of precast wall body stalk part and being arranged on the L-shaped fixture of precast wall body corner.
Compared with prior art, the present invention's it is a technical advantage that:
