Abstract
The invention discloses a method for mounting embedded interior forms of a cast-in-place hollow floor. The method is characterized by comprising steps of 1, manufacturing the embedded interior forms from light solid fillers according to sizes smaller than the thickness of the cast-in-place floor; 2, drilling holes on a bottom formwork of the cast-in-place floor when the bottom formwork of the cast-in-place floor is erected; 3, binding bottom reinforcing steel bars of the floor on support steel tubes by reinforcing iron wires; 4, fixedly welding steel square tubes on the bottom reinforcing steel bars of the floor; 5, fixing the embedded interior forms on the steel square tubes by adhesive and clipping chamfers at a lower opening of each embedded interior form; 6, fixedly binding the embedded interior forms on the bottom reinforcing steel bars of the floor; and 7, binding top reinforcing steel bars of the floor, pouring concrete of the floor and repeatedly lightly vibrating the concrete by the aid of a small vibrating bar. The steel square tubes are parallel to short sides of the embedded interior forms. The method has the advantages that problems of cracks, holes and voids and pits of a floor formed by means of pouring are solved, and the cost and material consumption are low.
Description
Technical field
The present invention relates to technical field of concrete construction, particularly relate to cast-in-situ hollow floor plate embedded inner mold mounting method, be mainly used in the Cast-in-situ Concrete Structural Engineering imbedding interior die body in floor.
Background technology
At present, the Span Slab of the particularly large public building of the cast-in-place concrete floor in the middle of building engineering construction, for the energy consumption that saves material, reduces, reduces the objects such as floor gravity load, adopts filling type cassette ceiling structure design more and more widely.Cassette ceiling in construction because slab thickness is thinner, concrete vibrating not easily, internal mold the process difficulties such as easily to float, easily cause build shaping after floor form the mass defect such as hole, crack and voids and pits, not only do not play the effect reducing floor deadweight, cause hidden danger of quality on the contrary.
Summary of the invention
Object of the present invention is exactly the above-mentioned shortcoming existed for prior art, cast-in-situ hollow floor plate embedded inner mold mounting method is provided, the size specification of internal mold is controlled by designing suitable size, fix internal mold by square steel pipe welding, bonding and iron wire colligation, guarantee the construction quality of cassette ceiling.
The object of the present invention is achieved like this: cast-in-place concrete hollow floor slab embedded inner mold mounting method, is characterized in that: carry out in accordance with the following steps:
1, according to the thickness being less than cast-in-situ floor, make embedded inner mold with waterproof, fire-retardant light solid obturator, length and width adjust according to concrete floor size.Described light solid obturator is EPS plate or other light foam class materials.
2, when installing template bottom cast-in-situ floor, the layout in conjunction with on-the-spot embedded inner mold determines spacing hole of drill diameter 10mm in template bottom cast-in-situ floor.
3, reinforcing iron wire is passed template bottom cast-in-situ floor through pre-drilled hole, floor slab bottoms reinforcing bar binding is fixing on supporting steel pipe.
4, be fixed on floor slab bottoms reinforcing bar by steel square tubes soldering, steel square tube is parallel to the short side direction of embedded inner mold, vertical with the long side direction of embedded inner mold.
5, embedded inner mold adhesive is fixed in steel square tube, the end opening of every block embedded inner mold cuts out the chamfering of m × n, the concrete magnitude numerical value of m, n is determined according to embedded inner mold size, be beneficial to concrete discharging and trickling, the concrete of embedded inner mold bottom is made to be more prone to, by fully flowing of vibrating, form closely knit entirety.
6, by colligation internal mold iron wire, embedded inner mold colligation is fixed on floor slab bottoms reinforcing bar, guarantees formation entirety, prevent from floating.
7, after embedded inner mold system is installed and fixed, colligation floor slab tops reinforcing bar, builds floorslab concrete then, according to the gap of embedded inner mold, repeatedly vibrates lightly, guarantee compactness with small vibrating rod.
Compared with prior art, advantage of the present invention is: opposing concrete buoyancy and produce because of concrete vibrating distortion displacement Be very effective, build shaping after floor there are not the quality problems such as crack, hole, voids and pits, cost is lower, and materials are less.

Detailed description of the invention
For further describing the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described.
As shown in the figure, the mounting method of cast-in-place concrete hollow floor slab embedded inner mold, is characterized in that: carry out in accordance with the following steps:
1) make embedded inner mold 1 according to cast-in-situ floor thickness EPS plate, slab thickness is 300mm as shown in FIG., then embedded inner mold 1 suitable for making is that 200mm is thick.For convenience of embedded inner mold 1 installation and concrete discharging and vibrate, be made as 1000mm × 250mm specification size.
2) when installing template bottom cast-in-situ floor, hole in template according to a determining deviation, particular location is determined in conjunction with the layout of on-the-spot embedded inner mold 1, pore size about 10mm.
3) reinforcing iron wire 4 is passed template bottom cast-in-situ floor through pre-drilled hole, floor slab bottoms reinforcing bar 5 colligation is fixing on supporting steel pipe.
4) be weldingly fixed on floor slab bottoms reinforcing bar 5 by steel square tube 2, as shown in the figure, steel square tube 2 is parallel to the short side direction of embedded inner mold 1 to particular location, vertical with the long side direction of embedded inner mold 1.
5) embedded inner mold 1 adhesive is fixed in steel square tube 2, as shown in Figure 2, the end opening of every block embedded inner mold 1 cuts out the chamfering of m × n, the concrete magnitude numerical value of m, n is determined according to embedded inner mold 1 size, be beneficial to concrete discharging and trickling, the concrete of embedded inner mold 1 bottom is made to be more prone to, by fully flowing of vibrating, form closely knit entirety.
6) after embedded inner mold 1 and steel square tube 2 are fixed, by colligation internal mold iron wire 3, embedded inner mold 1 colligation is fixed on floor slab bottoms reinforcing bar 5, guarantees formation entirety, prevent from floating.
7), after whole embedded inner mold 1 system is installed and fixed, colligation floor slab tops reinforcing bar 6, builds floorslab concrete then, according to the gap of embedded inner mold 1, repeatedly vibrates lightly, guarantee compactness with small vibrating rod.
