Abstract
The utility model discloses a shear wall template internal stay used for construction, wherein concrete mortar (2) is densely poured into a PVC pipe (1). The concrete mortar (2) is densely poured into the PVC pipe (1) during the manufacturing process, and can serve as a template internal stay after reaching certain intensity. The utility model is a shear wall template internal stay used for construction, which has a simple process, reliable performance, convenient manufacture and low cost.
Description
Technical field
The utility model relates to a kind of shear wall or thin-walled column formwork erection inner support, particularly relates to a kind of construction with shear wall or the used pvc pipe mortar inner support of thin-walled column formwork erection.
Background technology
In existing reinforced concrete shear wall or thin-walled column construction, after the shear force wall reinforcing steel bar colligation is intact, what adopt is that low-grade mortar inner support or 20 reaches the inner support of above indented bars as template, its effect is to guarantee that the interior space dimension of shear wall or thin-walled column two cheek boards is that the structure design size is (or than design minimizing 5mm, the expansion that produces because of extrusion die plate during with counteracting concreting), as long as formwork reinforcement is reliable, the physical dimension that forms after the concreting just can meet design requirement.
But have following shortcoming in above two kinds of inner support manufacturing process and after the moulding: low-grade mortar inner support need install template when making, stir mortar, operations such as stripping, and take bigger place in order to processing and fabricating, the label of low mortar is lower than design concrete label simultaneously, influences the mechanical property of concrete member; Indented bars is unfavorable for saving cost as the inner support waste material, simultaneously, because of inner support reinforcing bar unprotect layer, forms penetrating passage behind the corrosion of steel bar, influences the function of use in house.
The utility model content
Technical problem to be solved in the utility model provides a kind of dependable performance, construction simple in structure, easily manufactured, with low cost installs inner support with shear wall formwork.
In order to solve the problems of the technologies described above, the construction that the utility model provides installs inner support with shear wall formwork, the closely knit concrete mortar that is perfused with in pvc pipe.
Adopt the construction of technique scheme to install inner support with shear wall formwork, employing be to be the closely knit concrete mortar of perfusion in the pvc pipe of 16mm (the same concrete of this mortar proportioning, but remove coarse aggregate) at diameter.After this inner support completes, cover film, gunnysack moisture-keeping maintaining, or move to the maintenance of concrete standard fog room.At least maintenance was treated the reinforcing bar binding moulding after 7 days, and it is positioned over the position that need install inner support.Adopt this construction to install inner support with shear wall formwork, do not need to install template during making, stir operations such as mortar, stripping, do not need to take bigger place in order to processing and fabricating yet, do not need indented bars to be used as the inner support waste material, help saving cost, do not form penetrating passage after not having corrosion of steel bar, can not influence the function of use in house.
In sum, the utility model is that a kind of dependable performance, construction simple in structure, easily manufactured, with low cost install inner support with shear wall formwork.
Description of drawings
Fig. 1 is the utility model material profile schematic diagram;
Fig. 2 is that the utility model material is settled plan view in shear wall;
Fig. 3 is that the utility model material is settled sectional drawing in shear wall.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1: at diameter is the closely knit concrete mortar 2 that is perfused with in the pvc pipe 1 of 16mm.
Referring to Fig. 1, during this inner support of processing and fabricating, intercept the pvc pipe 1 of design length earlier with Abrasive cutting off machine, then it is tied into a bundle (being convenient to) toward its interior dry patching mortar, last toward pvc pipe 1 interior filling concrete mortar 2 (this mortar can adopt the preceding mortar in order to moistening delivery pump pipeline of each concreting), adopt the reinforcing rod tamping closely knit while clogging.Closely knit for ease of pvc pipe 1 inner concrete, also bundled pvc pipe 1 can be placed on the dull and stereotyped bumper, fill in i.e. vibration behind the material in the pvc pipe 1, filler vibrates again again, and is closely knit full in pvc pipe 1.The mortar that exceeds pvc pipe 1 part should be rejected.For ease of processing and fabricating, pvc pipe 1 embedded back-up sand slurry can be processed configuration at the scene.After this inner support completes, cover film, gunnysack moisture-keeping maintaining, or move to the maintenance of concrete standard fog room.
As Fig. 2, shown in Figure 3: PVC mortar inner support is made and maintenance after 7 days at least, treat shear wall or the moulding of thin-walled column reinforcing bar binding, this PVC mortar inner support is held on the cage of reinforcement gets final product, 3 install inner support for shear wall formwork of the present utility model, 4 is the shear wall vertical reinforcement, and 5 is the shear wall horizontal reinforcement.
