Abstract
The invention relates to a concrete component, in particular to an L-shaped combined pillar applied to civil engineering. The L-shaped steel pipe-steel framework recycled concrete combined pillar is composed of a steel framework, a steel pipe and recycled concrete, wherein the steel framework is located in the center of an L-shaped pillar and can improve the stress performance of branch parts of the L-shaped pillar; the L-shaped steel pipe is located outside, concrete in the steel pipe is in a three-directional stressed state, deformation of the concrete is restrained, and application of brittle high-strength concrete to the L-shaped pillar is facilitated; the recycled concrete can effectively improve the corrosion resistance of the pillar, resources are saved, and the environment is protected. The L-shaped steel pipe-steel framework recycled concrete combined pillar is a main component of a framework structure in a high-rise and large-span building, and has the advantages of being high in bearing force, high in rigidity, light in weight, good in plasticity and tenacity, good in impact resistance and fatigue resistance, good in vibration resistance and good in durability, saving energy, protecting the environment and the like.
Description
Technical field
Having the present invention relates to a kind of concrete component, particularly related to a kind of L shaped concrete column for civil engineering, is a kind of novel L shaped cross section coupled column.
Background technology
Current social, along with the development of Super High and long span building, common reinforced concrete post has been not suitable for use in the heavily loaded post under larger load.In this case, round steel pipe-steel reinforced concrete coupled column and rectangular steel tube-steel reinforced concrete coupled column have been there is.But, because people are more and more higher to the requirement of architectural environment, especially building structure and room layout more and more to be paid attention to, the sectional dimension of common steel tube-steel reinforced concrete heavy duty post is often greater than the thickness of body of wall, affect the use of the interior space, be difficult to meet the requirement that building is attractive in appearance.In order to address this problem, there is again afterwards the form of structure of L shaped steel core concrete column.
The advantage of L shaped steel core concrete column structural system is more outstanding, and scholar both domestic and external, expert have started this to be studied.L shaped steel core concrete column, due to the existence of its outer steel pipe, has retrained concrete distortion to a certain extent, and for the application of fragility high-strength concrete provides space, and construction technology is simple, does not need assembling reinforcement skeleton and formwork supporting plate.But be not the significantly improved bearing capacity of pillar of L shaped steel core concrete column, when building structure has high requirements to bearing capacity, will increasing section size, can make equally indoor corner angle outstanding, and for L shaped post, long post limb easily produce shear lag phenomenon.
Simultaneously, in the present circumstance, waste concrete in the building waste that the whole nation removes from old building every year just has 1,360 ten thousand tons, add that annual newly constructed house produces the waste concrete that the building waste of 4,000 ten thousand tons produces, the environmental problem of its huge disposal cost and thus initiation is also very outstanding.In order to reduce to greatest extent the exploitation to natural resource, must increase to greatest extent the regeneration to building waste.Therefore the processing of building waste and the research of application technology and application are imperative.Yet, at present due to the inherence damage of regeneration aggregate and due to its adsorption the water absorption rate that causes of the old mortar of one deck large, cause intensity, shrinkage and the endurance quality etc. of its regeneration concrete being made into poor compared with ordinary concrete, greatly limited its scope of application.
Therefore, the present invention is under above-mentioned background, a kind of novel L shaped steel pipe-reinforcing bar regeneration concrete coupled column has been proposed, this kind of coupled column combines the advantage of L shaped steel core concrete column, combined steel and concrete column, regeneration concrete post, resource pressure and environmental pressure have been alleviated, the application and development space of having widened greatly the L shaped Section Column of concrete, has very important Research Significance.
Summary of the invention
The object of this invention is to provide a kind of L shaped steel pipe-reinforcing bar regeneration concrete coupled column; this Novel combined column has not only improved the stress performance of common L shaped steel core concrete column, and takes full advantage of discarded concrete, has accomplished effective utilization of refuse; save resource, protected environment.
The present invention is achieved through the following technical solutions: reinforcing bar is formed by Plate Welding, regeneration concrete is positioned at the inside of steel pipe, concrete parcel reinforcing bar, it is characterized in that: steel pipe is around concrete L shaped, reinforcing bar is welded into L shaped, reinforcing bar is positioned at the center of L shaped steel pipe, coaxial with L shaped steel pipe, and interior reinforcing bar is connected with base plate and is fixed together by welding or bolt with steel pipe.LXing Zhu center refers to the center of rectangle part on limb, the T-shaped layout of reinforcing bar (2), and two the vertical-shaped post of reinforcing bar bottoms are fixed together.When in the present invention, the shape of reinforcing bar is with arrangement situation, repetition test obtains.
The reinforcing bar that is positioned at L shaped post the inside has improved the stress performance of limb portion, has improved supporting capacity and the ductility of L shaped post; Make full use of discarded building waste, form regeneration concrete, accomplish twice laid, energy conservation, environmental protection; Due to the existence of interior reinforcing bar, to compare with common L shaped concrete filled steel tube, its anti-seismic performance significantly improves.
Advantage of the present invention and effect are:
1. make full use of discarded building waste, form regeneration concrete, accomplish twice laid, energy conservation, environmental protection;
2. reinforcing bar is positioned at the inside of L shaped steel core concrete column, is subject to outside concrete protection, has good fire-resistant, decay resistance;
3. steel pipe inner concrete, in three-phase pressured state, has retrained concrete distortion, for the application exhaust of fragility high-strength concrete space;
4. the existence of reinforcing bar, has improved the stress performance of limb portion, has improved the supporting capacity of coupled column;
5. can first construct reinforcing bar, steel pipe, be connected and fixed reinforcing bar, steel pipe at bottom welding or bolt, the then vertical muscle of colligation and stirrup are poured into a mould regeneration concrete after forming skeleton, thereby formed superposed column;
6. due to the existence of reinforcing bar, steel pipe, improve the ductility of post, improved the ultimate bearing capacity of post, be conducive to earthquake zone seismic design;
7. widen the application and development space of L shaped post, beautified architectural appearance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of L shaped steel pipe-reinforcing bar regeneration concrete coupled column.
In figure: 1 is steel pipe, 2 is reinforcing bar, and 3 is regeneration concrete.
The specific embodiment
The present invention can realize in general concrete member factory with reference to drawing and description.Reinforcing bar is formed by Plate Welding, regeneration concrete is positioned at the inside of steel pipe, concrete parcel reinforcing bar, steel pipe is around concrete L shaped, reinforcing bar is welded into T shape, reinforcing bar 2 is positioned at the center of L shaped steel pipe, coaxial with L shaped steel pipe, and interior reinforcing bar is connected with base plate and is fixed together by welding or bolt with steel pipe.LXing Zhu center refers to the center of rectangle part on limb, the T-shaped layout of reinforcing bar, and two the vertical-shaped post of reinforcing bar bottoms are fixed together.
