Abstract
The invention relates to a section limit device for a shear wall of a high-rise building and a fabrication method thereof. The limit device is characterized by being a concrete prefabricated part, wherein, the core part of the prefabricated part is equipped with a hollow pipe fitting, the length of the prefabricated part is equal to that of the hollow pipe fitting, the section of the prefabricated part is in a rectangular shape, and the hollow pipe fitting is a plastic pipe; and the limit device is molded through a one-time casting process by utilizing a die. The fabrication method of the limit device comprises the following concrete steps: (1) designing the die according to the section size of the shear wall; (2) cutting the hollow pipe fitting into segments according to the section size of the shear wall, and then sheathing the pipe fitting segments on bolts of the die; (3) horizontally arranging the die, casting the die with concrete, and placing the hollow pipe fitting in the concrete; and (4) curing until the strength reaches the standard, and then disassembling the die to finally obtain the prefabricated limit device part. Compared with the prior art, the limit device has the advantages of simple structure, accurate size, high strength, obvious effect and unrestricted machining site, and the size of the limit device can be optionally adjusted according to the section size of the shear wall, thus meeting the application requirement for a plurality of the small-section shear walls and being beneficial to realizing batch production.
Description
Technical field
The present invention relates to the highrise building field, relate in particular to a kind of highrise building shear wall cross section stop and preparation method thereof.
Background technology
Along with the customer is more and more high to the highrise building shockproof requirements; Shear wall structure by more applications in highrise building; And the useful cross section that guarantees shear wall is the difficult point of construction; For guaranteeing the size in shear wall cross section, generally adopt the conventional cement mortar cushion block, to be that the cushion block colligation is not firm drop its shortcoming easily; Utilize plastic pipe to support two side templates in addition, but, all can not well guarantee the cross section of shear wall fully because of plastic tube intensity fractures inadequately easily.
Summary of the invention
The purpose of this invention is to provide a kind of highrise building shear wall cross section stop and preparation method thereof, simple in structure, cost is low, can be according to the size batch making shear wall cross section stop in shear wall cross section, and size is accurate.
For solving the problems of the technologies described above, technical scheme of the present invention is:
Highrise building shear wall cross section stop is concrete precast element, and prefabricated component heart portion is provided with a hollow pipe fitting, and preform length and hollow pipe fitting are isometric.
Said prefabricated component cross section is a rectangle.
Said hollow pipe fitting is a plastic pipe.
The preparation method of said stop is characterized in that, through the casting mold one-time cast-forming, its concrete operations step is:
1) according to shear wall sectional dimension designing mould; Mould comprises rectangular shaped rim, bolt, partition; In the rectangular shaped rim, many bolts are parallel evenly arranges, and is provided with partition between two bolts; The bolt two ends place in the opposite side rectangular shaped rim through hole, and the rectangular shaped rim inset spacing that bolt connected is from consistent with the shear wall sectional dimension;
2) with hollow pipe fitting by the shear wall sectional dimension section of being cut into, hollow pipe fitting is enclosed within on the bolt of mould, the hollow pipe fitting two ends withstand on respectively on the rectangular shaped rim inner edge, with nut bolt and rectangular shaped rim are linked together;
3) mould is kept flat on the ground, rectangular shaped rim is filled, wherein the hollow pipe fitting parcel with concrete;
4) pour into a mould the laggard capable maintenance that finishes, treat that intensity is removable rectangular shaped rim and bolt after qualified, obtains a plurality of stop prefabricated components.
Compared with prior art, the invention has the beneficial effects as follows: simple in structure, size is accurate; Intensity is high, and effect is obvious, and the processing place is unrestricted; The construction loss is little; Size can arbitrarily be adjusted according to the size in shear wall cross section, can satisfy the application of multiple small bore shear wall, and convenient the realization produced in batches.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is a processing mould structure sketch map of the present invention.
Among the figure: 1-concrete 2-plastic pipe 3-rectangular shaped rim 4-bolt 5-cuts off the 6-nut
The specific embodiment
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
Seeing Fig. 1, is highrise building shear wall of the present invention cross section stop example structure sketch map, and this stop is a concrete precast element, and square C30 concrete 1 heart portion of 50mm is provided with a 14mm hollow plastic pipe 2, and preform length and plastic pipe are isometric.Produce for convenient, the prefabricated component section selection is a rectangle, and for reducing production costs, hollow pipe fitting is generally selected plastic pipe.
Seeing Fig. 2, is processing mould structure sketch map of the present invention, and the preparation method of said stop is through this mould one-time cast-forming, and its concrete operations step is:
1) according to shear wall sectional dimension designing mould; Mould comprises rectangular shaped rim 3, φ 12mm bolt 4, the steel plate system partition 5 of 50mm square steel control; Many bolts 4 are parallel in the rectangular shaped rim 3 evenly arranges; Be provided with between two bolts 4 and cut off 5, bolt 4 two ends place in opposite side rectangular shaped rim 3 through holes, and rectangular shaped rim 3 inset spacings that bolt 4 is connected are from consistent with the shear wall sectional dimension;
2) with plastic pipe 2 by the shear wall sectional dimension section of being cut into; Plastic pipe 2 is enclosed within on the bolt 4 of mould, plastic pipe 2 two ends withstand on respectively on rectangular shaped rim 3 inner edges, with nut 6 bolt 4 and rectangular shaped rim 3 are linked together then; φ 14mm plastic pipe 2 internal diameters and φ 12mm bolt 4 diameters coupling; Satisfy bolt and pass through, and guarantee the intensity of plastic pipe in the casting process, do not take place to become bent;
3) mould is kept flat on the ground, with C30 concrete 1 rectangular shaped rim 3 is filled, plastic pipe 2 parcels wherein;
4) pour into a mould the laggard capable maintenance that finishes; Treat that intensity is removable rectangular shaped rim 3 and bolt 4 after reaching more than the C15, obtain a plurality of stop prefabricated components, stop can be through the through-wall bolt reliable fixation between two-layer template; Its compressive strength is higher can not damaged by pressure; Can guarantee the sectional dimension of shear wall, avoid of the maintenance of cast later stage, also improve the quality of engineering when having lowered construction cost body of wall.
