Description
Technical field
The invention belongs to technical field of building construction, relate to the construction of constructional column reinforcing bar in construction work secondary structure.Be specifically related to a kind of construction method of reserved constructional column hole on beam slab.
Background technology
For improving the anti-seismic performance of multistory building masonry structure, need appropriate site in the masonry in house to arrange reinforced concrete post and be connected with collar tie beam, the common stability strengthening building, this reinforced concrete post is just called as constructional column usually.And the way of traditional constructional column reinforcing bar is generally after beam slab concrete placings completes; adopt the mode bar planting of boring; its construction process is generally: preparation of construction, fixed point location, boring, removing floating dust, inject colloid, anchor into reinforcing bar, reinforcing bar corrects, solidification protection, self-inspection and the transfer project acceptance inspection, there is the shortcomings such as complex procedures, poor operability, difficulty of construction are large in it.
There are two outstanding drawbacks in above-mentioned construction method: one is that whole operation expense of taking a lot of work is expected, delays the cycle of construction; Two is in construction, need boring, and the inequality that high-frequency vibration can cause beam slab internal stress distribute and easily in beam slab opening area generation fine cracks, beam and slab structure being caused damage.
Summary of the invention
In order to solve the deficiency of existing constructional column pore reinforced construction method, the invention provides a kind of construction method of reserved constructional column hole on beam slab.Concrete technical scheme of the present invention is as follows:
A construction method for reserved constructional column hole on beam slab, carry out as follows:
Step one: with the beam-slab template framework 3 of construction formwork splicing in order to build beam slab; In beam-slab template framework 3, need the position that constructional column is set to put domatic steel plate base 11; The consistent size of described domatic steel plate base 11 bed-plate dimension and constructional column, domatic steel plate base 11 end face is less than the size of its bottom surface, is up-small and down-big, that surrounding becomes domatic metal sheet roof covering;
Step 2: the hole backstay 12 being welded with more than four or four on the end face of domatic steel plate base 11 is vertical; Described hole backstay 12 is reinforcing bar with ribbing; The length of hole backstay 12 is greater than the degree of depth of beam-slab template framework 3;
Step 3: coat release agent on the surface of domatic steel plate base 11 and hole backstay 12;
Step 4: at each hole backstay 12 outer socket PVC sleeve pipe 2, the outer wall of PVC sleeve pipe 2 all smears one deck release agent;
Step 5: cavity concrete slurry being filled up beam-slab template framework 3, and leave standstill; Until concrete slurry solidifies out into concrete beam plate 4;
Step 6: beam-slab template framework 3 is removed from concrete beam plate 4 surface; PVC sleeve pipe 2 is taken out place above concrete beam plate 4; Domatic steel plate base 11 is removed from the bottom of concrete beam plate 4 together with hole backstay 12.
Preferred scheme is, after PVC sleeve pipe 2 is socketed in hole backstay 12, is bent downwards the upper end of PVC sleeve pipe 2, namely makes PVC sleeve pipe 2 in inverted J-shaped.
Preferred scheme is, the vertical interval between the top port of PVC sleeve pipe 2 and hole backstay 12 top is not less than 3cm.
Preferred scheme is, the thickness of domatic steel plate base 11 is not less than 1cm.
The advantage that the present invention exists has:
The operation of the inventive method is simple, workable, difficulty of construction is little, and can not cause damage to the intensity of beam slab, thus shortens construction period, save people's material resources cost and ensure that the architecture quality of building.What time following concrete outstanding embodiment is:
1) the main muscle of structure is destroyed for avoiding when this method avoids traditional construction, and the process that structure protective layer is chiseled---this process is difficult to operation because structural beam slab tendon protective layer thickness thinner (being generally 1.5 ~ 2cm) and the disturbance of building in concrete process make the variable thickness of reinforcement cover);
2) this method avoids the boring procedure in traditional construction---and in fact, at the scene in practice of construction process, be difficult to implement the regulation of the regulation (hole depth is at least 10cm) of the basic anchorage length of bar planting according in " concrete structure reinforcement design specifications GB50367-2006 " to the bore operation of beam slab;
3) this method avoids the scale removal process of dust and water in traditional construction mesopore---need in traditional handicraft process to clean out dust and water in hole with hairbrush and blower fan;
4) this method avoids injecting glue process---this process need check colloid quality, and needs the air purge in got out hole in work progress, namely avoids air to be enclosed in duct by colloid, and this operation can not be disturbed before colloid solidification in addition; Difficulty of construction is very large.

Detailed description of the invention
Now further describe design feature of the present invention by reference to the accompanying drawings.
A construction method for reserved constructional column hole on beam slab, carry out as follows:
Step one (see Fig. 1): with the beam-slab template framework 3 of construction formwork splicing in order to build beam slab; In beam-slab template framework 3, need the position that constructional column is set to put domatic steel plate base 11; The consistent size of described domatic steel plate base 11 bed-plate dimension and constructional column, domatic steel plate base 11 end face is less than the size of its bottom surface, is up-small and down-big, that surrounding becomes domatic metal sheet roof covering;
Step 2 (see Fig. 1): the hole backstay 12 being welded with more than four or four on the end face of domatic steel plate base 11 is vertical; Described hole backstay 12 is reinforcing bar with ribbing; The length of hole backstay 12 is greater than the degree of depth of beam-slab template framework 3;
Step 3 (see Fig. 1): coat release agent on the surface of domatic steel plate base 11 and hole backstay 12;
Step 4 (see Fig. 2): at each hole backstay 12 outer socket PVC sleeve pipe 2, the outer wall of PVC sleeve pipe 2 all smears one deck release agent;
Step 5 (see Fig. 3): cavity concrete slurry being filled up beam-slab template framework 3, and leave standstill; Until concrete slurry solidifies out into concrete beam plate 4;
Step 6 (see Fig. 4): beam-slab template framework 3 is removed from concrete beam plate 4 surface; PVC sleeve pipe 2 is taken out place above concrete beam plate 4; Domatic steel plate base 11 is removed from the bottom of concrete beam plate 4 together with hole backstay 12, namely completes the making of the concrete beam plate 4 offering preformed hole 5.
See Fig. 2, preferred scheme is, after PVC sleeve pipe 2 is socketed in hole backstay 12, is bent downwards the upper end of PVC sleeve pipe 2, namely makes PVC sleeve pipe 2 in inverted J-shaped.This structure can prevent in concrete placings process, and concrete slurry enters PVC sleeve pipe 2 and pollutes hole backstay 12, causes PVC sleeve pipe 2 and hole backstay 12 to condense into Unified Global, the problem that cannot dismantle.
Preferred scheme is, the vertical interval between the top port of PVC sleeve pipe 2 and hole backstay 12 top is not less than 3cm.
Preferred scheme is, the thickness of domatic steel plate base 11 is not less than 1cm.With nail, domatic steel plate base 11 is fixed on the end face of beam-slab template framework 3 groove, prevent when concreting slip, the placement location of domatic steel plate base 11 offsets; Domatic steel plate base 11 is made as domatic, contributes to the later stage conveniently to prize, be beneficial to the demoulding.
Further preferred version is: hole backstay 12 adopts diameter to be the reinforcing bar of 10 or 12mm.
Further preferred version is: PVC sleeve pipe 2 is made up of the water power PVC spool of Φ 16mm conventional in building operations.
