Description

Built-in spiral stirrup Covered with Angles concrete column

Technical field

The invention belongs to a kind of building structural element of construction engineering technical field, particularly a kind of built-in spiral stirrup Covered with Angles concrete column.

Background technology

Covered with Angles concrete structure, is a kind of new structure of Steel concrete combining structure, with the advantage of steel work and reinforced concrete structure: (1) member is single, is convenient to batch production, mechanization production; (2) easy to connect, use flexibly; (3) stress performance is good, and degree of fire resistance is high; (4) building structure and process pipelines can be connected, with any position of beam column, embedded iron parts needn't be set; (5) technical-economic index is advanced.Therefore, Covered with Angles concrete structure has obtained deep research and extensive use at home and abroad.

Covered with Angles concrete column, as vertical supporting member important in Covered with Angles concrete structure, is compared with steel structure column, has that saving steel, joint structure are easy, a mode of transfer force advantage such as clearly; Compare and there is the advantages such as bearing capacity is high, ductility good, anti-seismic performance is good, speed of application is fast with ordinary reinforced concrete post, obtain the approval of engineering circles and be subject to numerous owners' welcome, so it is more and more widely used in heavy industry factory building (particularly large thermal power plant factory building) and highrise building.But, because Covered with Angles concrete column construction features are four jiaos of elongated configuration sole bar angles in cross section, between angle steel, adopt transverse connection (as reinforcing bar, batten plate etc.) be welded on angle steel frange plate, concrete only contacts with angle steel inner surface, its adhesion stress is less, do not have topping constraint sole bar angle outwardly-bent simultaneously, therefore, Covered with Angles is mainly the effect that relies on transverse connection, the concrete of about beam core, guarantee Covered with Angles and concrete deformation coordination co-operation, so it is not strong to the effect of contraction of core concrete, can not give full play to the performance of steel and concrete bi-material.Along with height, span and the load size of factory building and building in engineering reality are increasing, in order to meet the strength and stiffness requirement of structural element, the form of reinforcement as still adopted, certainly will will strengthen sectional dimension of members, both to design and construction, caused difficulty, uneconomical not attractive in appearance again; If adopt steel structure column or steel core concrete column, will increase steel using amount and fire prevention, antirust processing cost, cost is high and uneconomical, does not meet engineering reality.Therefore, be necessary to propose a kind of rational Covered with Angles concrete column, not only can improve Covered with Angles concrete column bearing capacity, ductile performance and anti-seismic performance, and can reduce sectional dimension, steel using amount and reduce costs, reach the effect of economical rationality.

Summary of the invention

The technical problem to be solved in the present invention is to provide that a kind of supporting capacity is high, good working ductility, anti-seismic performance is superior, steel ratio is few, sectional dimension is little, easy construction built-in spiral stirrup Covered with Angles concrete column fast.

The present invention solves the problems of the technologies described above with following technical scheme:

Built-in spiral stirrup Covered with Angles concrete column, comprise sole bar angle, transverse connection, spiral stirrup, longitudinal reinforcement and core concrete, each angle of post arranges a sole bar angle, between sole bar angle, with transverse connection, connect, transverse connection is welded in inner side or the outside of sole bar angle frange plate, form Covered with Angles skeleton, at spiral stirrup inwall, longitudinal reinforcement is set and forms spiral reinforcement cage, spiral reinforcement cage is placed in to Covered with Angles frame center, the central axis of spiral reinforcement cage overlaps with the central axis of Covered with Angles skeleton, core concrete is filled up in Covered with Angles skeleton inner space, form built-in spiral stirrup Covered with Angles concrete column.

Described longitudinal reinforcement colligation or be welded at spiral stirrup inwall, the quantity of longitudinal reinforcement is no less than 4.

Described spiral stirrup external surface is 30~50mm to the minimum range of transverse connection inner surface.

Described spiral stirrup adopts HPB300 or the HRB335 reinforcing bar cold bending that diameter is 6~12mm to process, and longitudinal reinforcement adopts HRB335 or the HRB400 reinforcing bar that diameter is 10~16mm.

Described sole bar angle adopts Q235 steel, Q345 steel, Q390 steel, Q420 steel, Q460 to make.

Described transverse connection adopts reinforcing bar or batten plate, and wherein reinforcing bar adopts HRB335 or HRB400 reinforcing bar, and batten plate adopts Q235 steel, the little 1~2mm of Thickness Ratio sole bar angle.

Described core concrete adopts ordinary concrete or high performance concrete.

Simple structure of the present invention, easy construction, cost are low, can effectively prevent transverse connection generation flexing, improve the effect of contraction of Covered with Angles to core concrete, strengthened the collaborative work between Covered with Angles and core concrete, thereby improved bearing capacity, ductile performance, anti-seismic performance.

The built-in spiral stirrup Covered with Angles concrete column that the present invention proposes has following remarkable advantage:

1, built-in spiral stirrup Covered with Angles concrete column have that bearing capacity is high, the advantage such as good working ductility, anti-seismic performance are superior, easy construction, progress is fast, the duration is short.

2, spiral stirrup is to the constraint to spiral stirrup to the concrete between the constraint of core concrete, Covered with Angles and spiral stirrup of the constraint of core concrete, Covered with Angles, three's synergy, strengthen ductility and the bearing capacity of Covered with Angles concrete column, and effectively improved its anti-seismic performance.

3, significantly improved the common Covered with Angles concrete column steel pipe shortcoming not strong to core concrete effect of contraction, effectively prevent transverse connection generation flexing, give full play to the performance of Covered with Angles and core concrete bi-material, improved Covered with Angles concrete column strength and ductility.

4, the Covered with Angles concrete column that has overcome general form of reinforcement for meet the strength and stiffness of structural element require enlarging section size cause difficult, uneconomical, the not attractive in appearance and steel structure column of design and construction or steel core concrete column steel using amount greatly, the antirust complexity of preventing fires, shortcoming that cost is high.
