Description
Technical field
The invention belongs to technical field of civil engineering, in particular to the device of a kind of precast hollow concrete structure.
Background technology
In recent years, precast concrete is with its cheap cost, and outstanding performance, becomes the new lover of construction industry. its pattern variation, lighter in weight, in addition outstanding flexural strength and performance, it is made to be used widely at roadblock, tank, exterior wall, building beam column and furnishing fields, precast concrete can accelerate housing industrialization speed, is one of the emphasis of China's economic system reform. but now conventional precast concrete or prefabricated reinforced concrete are all cast in other places, time for precast hollow concrete structure, mostly what use in its casting process is type core or steel pipe or support shuttering, demolishing process is extremely loaded down with trivial details, waste huge manpower and materials, if not removing and a large amount of ferrous materials can being wasted, the most important thing is, adopt and it is merely able in the hollow concrete mechanism that above-mentioned technique makes form an inner chamber, the concrete strcture method of all sides of described inner chamber realizes the effect forming spatial joins each other through described inner chamber, namely, the stiffening member of its both sides is not connected in its inner chamber, the mechanical property of the hollow concrete structure therefore produced is general, when there being earthquake, when wind pendulum and other forms of shock conditions, its adaptibility to response will show deficiency. therefore, how the reinforcement web member connecting both sides is set at hollow concrete structure inner chamber, and realize prefabricated effect, prepare a kind of can shorten the duration, simplify operational procedure, ensure construction quality building trade for the device of precast hollow concrete structure, become the technical barrier that precast concrete industry is researched and solved painstakingly.
Many insiders adopt the boring of precast hollow concrete structure, then inlay the method for muscle plate or pull bar, but the component of secondary processing and concrete structure integraty are poor, and the appearance of finished product is coarse and crude, and operates loaded down with trivial details, and operability is not strong, also have more advanced such as application number: a kind of concrete hollow board prefabricated components of 200410097220.7, comprise reinforced concrete strip base plate, reinforced concrete strip longitudinal vertical plate, longitudinal vertical plate is arranged on base plate, and form entirety, it is characterized in that described at least two piece longitudinal vertical plate is parallel or crossing, base plate is equipped with at least two built on stilts bodies forming cavitys or/and than the obturator of concrete lightweight, make somebody a mere figurehead body or/and be horizontal rib die cavity between obturator, in the horizontal rib die cavity of at least one between two longitudinal vertical plates, have one piece of horizontal structure frid supporting adjacent longitudinal vertical plate. when prefabricated components are applied to cored slab construction, built on stilts body or obturator can reduce amount for in-site pouring concrete, alleviate cored slab weight, for another example application number: the Chinese invention patent of 200810302587.6 discloses a kind of hollow die for pouring concrete filling on site, comprise outer wall and enclose the hollow matrix closing and being formed with cavity, it is characterized in that: described hollow matrix is provided with locking piece, described locking piece comprises self-locking hole and self-locking bar or band, locking piece is anchored in hollow matrix by anchorage element or locking piece is connected with the anchorage element being anchored in hollow matrix, it is moveable that self-locking hole is through on self-locking bar or band, cavity is provided with stiffener. but its hollow matrix is welded together by a lot of block plate, in addition there is a lot of connection and stiffener, its stopping property being required by casting process high, once there be the production failure leaked and will cause hollow concrete structure, and cannot take out after building, so causing the waste of iron and steel resource, moreover, owing to it is structure steel fabrication, the fabrication cycle of various component 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, it is provided that a kind of structure is simple, easy to use, the device for precast hollow concrete structure of dependable performance.
For achieving the above object, the technical solution used in the present invention is: the device of a kind of precast hollow concrete structure, the core tire comprising outer case and be arranged in casing, described core tire is flexibly connected with outer case, described core tire is provided with charge and discharge gas component, the stiffener putting hole running through core tire is set in described core tire, described core tire is made up of flexible materials, described core tire inside has cavity, described stiffener putting hole is connected wall and the isolation of core tire internal space by arranging, to ensure the resistance to air loss of core tire, described stiffener putting hole is set to some groups of spatial intersecting layout.
Described stiffener putting hole is the hole that to be arranged on core tyre sidewall corresponding, and position, described aperture arranges stiffener sealing mechanism.
In described stiffener putting hole, the stiffener stretched out at two ends is set.
In described stiffener putting hole, the stiffener stretched out at two ends is set.
