Abstract
The invention relates to a concrete prefabricated wall body and a vertical pouring hole remaining method thereof. A through vertical pouring hole is formed in the concrete prefabricated wall body corresponding to a cast-in-site section. The vertical pouring hole remaining method comprises producing an inflatable rubber core mold which is matched with the vertical pouring hole in diameter and length, drawing the rubber core mold to penetrate a tied wall body reinforced cage through a rope and enabling an inflatable nozzle to be placed externally; inflating the rubber core mold through an air pump, controlling the monitoring air pressure trough a pressure gauge during inflation and inflating to the specified pressure; fixing the upper side, the lower side, the left side and the right side of the rubber core mold when wall body concrete is poured; performing vibration from the bilateral sides of the rubber core mold simultaneously during concrete vibration to prevent the rubber core mold from moving laterally; deflating the rubber core mold and pulling out the rubber core mold after the concrete is finally set. According to the concrete prefabricated wall body, the design requirements can be met, the total weight of the wall body can be reduced, the wall body vertical pouring hole is reserved in the rubber core mold, the operation is simple, and the labor, the time and materials are saved.
Description
Technical field
The present invention relates to concrete prefabricated shear wall, specifically a kind of concrete prefabricated body of wall and vertical pouring hole placement method thereof.
Background technology
At present, when after the installation of precast shear wall body of wall, bottom reserved steel bar overlapping part concrete cast-in-situ section is built, the bubble of generation not easily discharges, and there is the shortcoming that speed of application is slow, quality is wayward, be difficult to guarantee cast-in-place position concrete turgor bottom body of wall.
Summary of the invention
The present invention is intended to solve existing prefabricated shear wall body and installs the problems referred to above existed, and provides a kind of and be convenient to quality control, is convenient to concrete prefabricated body of wall that the later stage builds and vertical pouring hole placement method thereof.
The technical scheme that the present invention solves the employing of described problem is:
A kind of concrete prefabricated body of wall, comprise the Cast-in-Situ Segment of body of wall body, body of wall body bottom portion, in described body of wall body, corresponding described Cast-in-Situ Segment is provided with the vertical plug hole of up/down perforation.
Further, described vertical plug hole is that one or interval arrange 2-3.
The placement method of the vertical plug hole of above-mentioned concrete prefabricated body of wall, carries out in the steps below:
A. mould is entered: make the inflating rubber core be applicable to the vertical plug hole diameter matches in body of wall, length, with wire saws, described rubber mandrel is penetrated in the good wall steel bar cage of colligation, and make charging connector be in outer placement, avoid sharp-pointed hard object to puncture rubber mandrel;
B. inflate: use air pump to inflate rubber mandrel, control monitoring air pressure with Pressure gauge during inflation, be inflated to the pressure of regulation;
Rubber mandrel upper and lower, left and right, for preventing rubber mandrel from floating, all be fixed by c. casting concrete: when building walls concrete; During concrete vibrating, to vibrate from rubber mandrel both sides simultaneously, prevent rubber mandrel from moving left and right;
D. form removal: after concrete final set, exits rubber mandrel, extracts rubber mandrel out.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
1. the prefabricated or concrete prefabricated body of wall of cast in situs finished product out, can meet design requirement;
2. with the concrete prefabricated body of wall of vertical plug hole, component gross weight is alleviated;
3. adopt rubber mandrel to reserve the vertical plug hole of body of wall, simple to operate, saving of labor, save time, economize material.
