Description
Technical field
The utility model relates to the concrete structure in the construction engineering technical field, especially a kind of web frame that is used for concrete structure.
Background technology
We know that reinforced concrete structure and encased structures are adopted by people for these years always in engineerings such as building, bridge.Reinforced concrete structure uses longitudinal reinforcement, and colligation becomes reinforcing cage (net) to be used as the skeleton of concrete structure with transverse reinforcement, this concrete structure provides functions such as good renitency (pulling force), shearing, torsion, yet this structure is wanted three process at least: one will shear, moment reinforcement; Two will become reinforcing cage (net) with shearing or crooked good reinforcing bar binding; Three will be with reinforcing cage (net) transportation and the installation that ties up.This three process all needs a large amount of artificial and time.Encased structures be with steel pipe as the skeleton in the concrete structure, when fluid concrete, also can be used as template, this has just saved a large amount of artificial, templates and time.Because of concrete is to be cast in the steel pipe, steel pipe has effect of contraction to concrete, can improve concrete bearing strength, and the concrete in the steel pipe has supporting role to steel pipe walls simultaneously, and is also helpful to the bearing strength that improves steel pipe.But encased structures has two big weakness: the one, and because of the steel pipe in this structure is to be exposed to concrete outside, steel pipe needs antirust and fire prevention is safeguarded; The 2nd, the concrete column of this structure is when being subjected to weather, Temperature Influence, steel pipe is different with concrete coefficient of thermal expansion and contraction, through after the cold and hot conversion repeatedly of certain number of times, the slit will appear between steel pipe and the concrete, at this moment the two just is difficult to the co-operation renitency, and this has caused very big hidden danger with regard to the quality of giving engineering.
Summary of the invention
In order to overcome the deficiency of above-mentioned technology, the utility model provides a kind of function that pressure-bearing (drawing) force intensity is big, resist shearing, torsion and antidetonation that not only has, and it is simple in structure, can accelerate speed of application, save material, save the labour, be not subjected to the weather Temperature Influence, fire prevention, ageing-resistant, anticorrosive, the web frame that is used for concrete structure that prolongs its application life.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with steel pipe, be placed with aperture on the tube wall of steel pipe.
The utility model can also be realized by following measure: the cross sectional shape of steel pipe can be circle, ellipse or polygon.Hole shape on the steel pipe walls can be circle, ellipse or polygon.Steel pipe can be straight tube or bend pipe.
The beneficial effects of the utility model are, owing to be placed with aperture on the tube wall of steel pipe, in being cast in the process of concrete column, concrete is closely linked steel pipe and concrete column by the aperture on the tube wall, form inseparable one, therefore this structure is compared with reinforced concrete structure and encased structures and is had the following advantages:
1, longitudinal reinforcement in the reinforced concrete structure and transverse reinforcement are stressed respectively, the easy unstability of longitudinal reinforcement under the big situation of pressure, and direction in length and breadth of the present utility model is an one, stressed jointly, therefore, can prevent the unstability of steel frame, and then steel pipe with holes more can improve the bearing strength of concrete structure on the wall.
2, reinforced concrete post uses longitudinal reinforcement colligation becomes loaded down with trivial details the wasting time and energy of reinforcing cage (net) operation with transverse reinforcement, but and the utility model produce in factory, therefore construction is simple, has the function that speed of application is fast, save material, save the labour.
3, the steel pipe in the encased structures is to be exposed to concrete outside, and steel pipe needs antirust and fire prevention is safeguarded, and the utility model is cast in the concrete, therefore has fire prevention, ageing-resistant, anticorrosive, the function that prolongs its application life.
4, encased structures is being subjected to weather, during Temperature Influence, steel pipe is different with concrete coefficient of thermal expansion and contraction, through after the cold and hot conversion repeatedly of certain number of times, the slit will appear between steel pipe and the concrete, bring very big hidden danger to engineering, and the utility model is in being cast in the process of concrete column, concrete is closely linked steel pipe and concrete column by the aperture on the tube wall, no matter weather, how temperature changes, concrete column forms inseparable one all the time with the utility model, the two bears external force simultaneously, therefore be not subjected to weather, Temperature Influence, it is big to have bearing capacity, the opposing shearing, the function of torsion and antidetonation, this structure provide safety assurance for the quality of engineering.
