Abstract
The utility model discloses an inner-thread large-hole grouting sleeve of a concrete precast component for housing industrialization. The sleeve comprises a sleeve body and a large grouting hole in the sleeve body; the sleeve body is of a slurry filling cavity structure; one end of the sleeve body is provided with an outer leakage steel rib insertion hole, and the other end of the sleeve body is provided with a steel rib connection thread hole; the end, in butt joint with a formwork, of the sleeve body is provided with a locating element used for preventing the sleeve body from rotating; inner threads are arranged in the steel rib insertion hole. In the production process, adjustment time for meeting the verticality requirement of the sleeve body in two directions is shortened; when the component is installed on a construction site, reworking time wasted due to the fact that an outer leakage steel rib can not be smoothly inserted is shortened; when the grouting sleeve serves as a component product at the same time, appearance quality is greatly improved; labor cost is lowered, production efficiency and installation efficiency are improved, and the grouting sleeve plays an important role in using and popularizing precast assembled integrated shear wall structures and promoting housing industrialization.

Grout sleeve technology is the core of fabricated assembly overall concrete shear wall structure, is the vertical critical component connecting of body of wall.When being prefabricated in the factory, grout sleeve to ensure that sleeve body vertical bottom face and grout hole do not want crooked requirement, to reduce the rejection and waste of job site while installing.
In production assembling process, there is following problem in existing grout sleeve (as shown in Figure 1): the one, cannot ensure sleeve body and wall bottom surface at right angle setting, and affect reinforcing bar and insert, install to cause to building-site and do over again; The 2nd, grout hole, air-vent easily rotate crooked, are difficult for ensureing and the vertical requirement of metope, affect the outward appearance of wallboard; The 3rd, grout hole separates with air-vent, causes the assembling of plant produced line to lose time, the problem that steam vent stops up.
Summary of the invention
The object of the invention provides a kind of internal thread macropore grout sleeve for house industrialization concrete prefabricated element.In process of factory production, adopt this novel grout sleeve, more easily ensure the verticality of grout sleeve and template, also can reduce the crooked of grout hole, simultaneously easy for installation, save time.
The technical scheme that the utility model adopted is for achieving the above object:
For an internal thread macropore grout sleeve for house industrialization concrete prefabricated element, comprise the large grout hole in sleeve body, sleeve body;
It in described sleeve body, is slurry filling cavity configuration;
Described sleeve body one end is provided with the reinforcing bar patchhole that leaks outside, and the other end is provided with steel bar joint screw hole;
Described sleeve body and template abutment end are provided with the keeper that prevents sleeve body rotation;
Described steel bar joint screw hole is connected with wall steel bar skeleton.
The beneficial effects of the utility model are:
1, the utility model in process of production, has reduced grout sleeve both direction and has vertically required the adjustment time used; When installation component, reduce the reinforcing bar that leaks outside and insert doing over again the time of having some setbacks at the construction field (site); As member product, presentation quality has had large increase simultaneously.Reduce cost of labor, improved the efficiency of producing and installing, to applying fabricated assembly overall shear wall structure, advanced Process of Housing Industrialization to play positive effect.
2, the utility model is more convenient for ensureing body and wall bottom surface verticality and grout hole and degree of gravity vertical forwall surface requirement in process of production, and mounting or dismounting are convenient, has also improved the installation rate of job site simultaneously, cuts the waste, and reduces costs.

Detailed description of the invention
Below in conjunction with accompanying drawing Fig. 1-6 and embodiment, the utility model is further illustrated.
For an internal thread macropore grout sleeve for house industrialization concrete prefabricated element, comprise the large grout hole 2 in sleeve body 1, sleeve body 1;
In described sleeve body 1, be slurry filling chamber 4 structures;
Described sleeve body 1 one end is provided with the reinforcing bar patchhole 5 that leaks outside, and the other end is provided with steel bar joint screw hole 3;
Described sleeve body 1 is provided with template abutment end the keeper 6 that prevents that sleeve body 1 from rotating;
Described steel bar joint screw hole 3 is connected with wall steel bar skeleton 13.Improve the power resistance strength of wallboard.
Described slurry is filled in chamber 4 and is equipped with strong concrete 15 to wrap the reinforcing bar 16 that leaks outside of lower face wall.
The described reinforcing bar patchhole 5 that leaks outside is provided with internal thread, screws togather and is fixedly connected with the reinforcing bar that leaks outside.
Described keeper 6 is two pits that sleeve body 1 end face arranges, and this pit coordinates butt with the projection arranging in template 9, prevents that sleeve body 1 rotation from having ensured large grout hole 2 vertically upward.The large grout hole 2 that has indirectly met sleeve body 1 is vertical with metope.
Described keeper 6 arranges two protruding gears for sleeve body 1 end face shoulder, and this protruding gear coordinates butt with the pit arranging in template 9, prevents that sleeve body 1 rotation from having ensured large grout hole 2 vertically upward.
