Description
Technical field
The invention belongs to technical field of civil engineering, particularly a kind of device for precast hollow concrete structure.
Background technology
In recent years, the cost that precast concrete is cheap with it, outstanding performance, become the new lover of building industry.The variation of its pattern, weight gentlier, outstanding flexural strength and performance in addition, it is used widely in roadblock, tank, exterior wall, building beam column and decoration field, precast concrete can be accelerated housing industrialization speed, is one of emphasis of China's economic system reform.But precast concrete or prefabricated reinforced concrete commonly used is all to cast elsewhere now, in the time of for precast hollow concrete structure, mostly that in its casting process, uses is core or steel pipe or support shuttering, demolishing process is extremely loaded down with trivial details, waste huge manpower and materials, if do not remove and can waste a large amount of ferrous materials, the most important thing is, be merely able to form an inner chamber in the hollow concrete mechanism that adopts above-mentioned technique to make, the concrete structure of all sides of described inner chamber can't realize forming through described inner chamber the effect that space connects each other, , do not connect the stiffener of its both sides in its inner chamber, the mechanical property of the hollow concrete structure of therefore producing is general, when earthquake is arranged, when wind pendulum and other forms of shock conditions, its adaptibility to response will show deficiency.Therefore, how at the hollow concrete structure inner chamber, the reinforced company's fitting that connects both sides to be set, and realize prefabricated effect, prepare a kind of can the reduction of erection time, simplify operational procedure, guarantee the device of the building trade of construction quality for precast hollow concrete structure, become the technical barrier that the precast concrete industry is researched and solved painstakingly.
Many insiders adopt the boring of precast hollow concrete structure, the method for then inlaying gusset or pull bar, but the member of secondary operations and concrete structure integraty are poor, and the appearance of finished product is coarse and crude, and complex operation, and operability is not strong; Also have more advanced as application number: a kind of concrete hollow board prefabricated components of 200410097220.7, comprise the rectangular base plate of reinforced concrete, the rectangular longitudinal vertical plate of reinforced concrete, longitudinal vertical plate is arranged on base plate, and form whole, it is characterized in that described at least two longitudinal vertical plates are parallel or crossing, at least two built on stilts bodies that form cavity are housed or/and than the obturator of concrete lightweight on base plate, make somebody a mere figurehead body or/and be the cross rib die cavity between obturator, a transversary frid that supports adjacent longitudinal vertical plate is arranged at least one the cross rib die cavity between two longitudinal vertical plates.When prefabricated components are applied to the cored slab construction, built on stilts body or obturator can reduce the Cast-in-place concrete consumption, alleviate cored slab weight, application number for another example: 200810302587.6 Chinese invention patent discloses a kind of hollow die for pouring concrete filling on site, comprise that outer wall encloses the hollow matrix that is formed with cavity, it is characterized in that: on described hollow matrix, be provided with locking member, described locking member comprises self-locking hole and self-locking bar or band, locking member is anchored in hollow matrix by anchorage element or locking member is connected with the anchorage element in being anchored at hollow matrix, it is movably that self-locking hole is through on self-locking bar or band, be provided with reinforcement in cavity.But its hollow matrix is welded together by a lot of block plates, there is a lot of connections and reinforcement in addition, high to its seal requirement in casting process, once there is leakage will cause the production failure of hollow concrete structure, and can't take out after building, so caused the waste of iron and steel resource, moreover, because it is structure steel fabrication, the fabrication cycle of various members is long, arrangement before building requires higher, wastes time and energy.
Summary of the invention
The invention reside in and solve above-mentioned technical barrier, a kind of device for precast hollow concrete structure of simple in structure, easy to use, dependable performance is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of device for precast hollow concrete structure, comprise outer case and be arranged on the core tire in outer case, described core tire and outer case are flexibly connected, be provided with the inflation/deflation member on described core tire, the reinforcement putting hole that runs through the core tire is set in described core tire.
