Description
Technical Field
The utility model relates to a reinforced structure of building structure specifically indicates a reinforced concrete does not have reinforcement support building structure of roof beam.
Background
At present, the reinforcing technology of the reinforced concrete flat slab is commonly provided with two forms.
The first form is: the column cap section enlarging method and the plate section enlarging method are adopted for strengthening, and the rigidity of the section can be improved through the method, so that the punching resistance and bending resistance bearing capacity of the column cap and the plate are improved. Because the column cap concrete has low strength and adopts a reverse column cap, the upper part of the column cap concrete is covered with soil and operated, and the reinforcement cannot be increased upwards.
The second form is: arranging concrete beams or steel beams between frame columns; the concrete beam adopted in the reinforcing method cannot meet the requirement of net height. In the reinforcing method, the steel beam is connected with the original concrete column through the chemical anchor bolt, rigid connection is difficult to achieve at the node, the original concrete column is damaged, and the construction site needs to be subjected to wet operation treatment to cause adverse effects on daily production activities.
Therefore, the conventional reinforced concrete flat slab reinforcing technology is not suitable for the conditions that the concrete strength is low, wet operation needs to be avoided in a construction field, and the slabs are not reinforced conditionally, and meets the reinforcing requirement of high construction speed. Due to the defects of the reinforcement method in practical application, the application of the reinforced concrete flat slab reinforcement technology is limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a reinforced concrete does not have reinforcement and supports building structure of roof beam, should consolidate and support building structure simple structure, construction swiftly.
The above object of the present invention is achieved by the following technical solutions: the utility model provides a reinforced concrete does not have reinforcement support building structure of roof beam, includes the concrete column, its characterized in that: the building structure further comprises a steel pipe column surrounding the concrete column from top to bottom, a gap between the steel pipe column and the concrete column is filled with concrete grouting, steel beams are welded around the top of the steel pipe column and are in an extending shape, the steel beams are fixedly connected with a floor, column feet are arranged at the bottom of the steel pipe column, and the column feet are anchored on the concrete floor.
The utility model discloses in, the concrete column is the rectangle post, the steel-pipe column is the rectangle steel-pipe column.
The utility model discloses a consolidate and support building structure, in the construction stage, can bear the produced shearing force and the moment of torsion of construction load, in the use stage, can bear the moment of flexure, and the wet operation of job site is avoided to shearing force and moment of torsion, consolidates fastly, the node can realize the rigid connection. The reinforced and supported building structure has high bending resistance and compression resistance bearing capacity, simple structure and quick construction.
The utility model discloses in, the girder steel is four I-shaped roof beams, and four I-shaped roof beams weld respectively in four sides of steel-pipe column.
The utility model discloses in, in four girder steels, through welding stiffening plate interconnect on the upper and lower flange plate of girder steel between two adjacent girder steels to reinforcing building structure's overall stability.
As a preferred embodiment, the size of the section of the steel pipe column is determined according to the actual size of the inner concrete section, the wall thickness of the steel pipe column is 25-30mm, the size of the section of the I-shaped steel beam is determined according to the actual stress condition, the thickness of the steel beam is 40-60mm, and the thickness of the stiffening plate is 30-50mm according to the actual stress analysis.
The utility model discloses a consolidate and support building structure is applicable to that the building floor headroom is less, and the structural concrete intensity is low, and the great and inconvenient condition of consolidating the transformation to the structural slab of structural slab upper portion load, through the utility model discloses can make connected node bear the moment of torsion to need not a mould in the work progress, can not handle structural slab upper portion, when satisfying the structural safety, improve construction speed and practice thrift component occupation space.
Compared with the prior art, the utility model discloses have as follows and show the effect:
(1) in the construction stage, the reinforcement is completely made of steel, so that field wet operation can be avoided, the construction is convenient, and the method has obvious economic benefit.
(2) In the normal use stage, under equal component cross-section, adopt the girder steel to have higher bending resistance bearing capacity for adopting reinforced concrete roof beam for the girder steel, can practice thrift the house headroom and reach more than 30%.
(3) The steel beam and the steel pipe column can be rigidly connected through the stiffening plates arranged annularly, and the shearing-resistant bearing capacity is higher compared with the steel beam and the reinforced concrete column node.
