Background technology
Steel structure system is easy to realize suitability for industrialized production, and standardization is made, and compared with conventional steel tendon concrete structure mode of construction, assembling type steel structure has advantages of " four joint one environmental protection ", belongs to green building.Domestic many high-rise steel structure central sill, post and wallboard can factory process be made at present, site assembly, but more floor or wallboard still adopt and need cast in situs to form.On the one hand, in the process of steel structure system construction, due to the reason of construction technology and the characteristic of constructional materials itself, cast in place concrete plate build the speed of application that obviously lags behind steel work main body frame with maintenance, it is discontinuous, not compact that the construction of two kinds of main members is connected, and do not become unimpeded continuous productive process, seriously restrict the assembling speed of application of steel structure system, made the advantage that steel building construction period is short, money collecting is fast can not get fully demonstrating.On the other hand, even the steel reinforced concrete plate of existing exploitation, after assembling construction, often in plate and plate junction or plate and beam junction, the medium-sized Steel concrete of plate is same material not, and contact surface is large, due to hogging moment and oblique shearing action, its contact surface is easy to produce shearing slip or concrete ftractures in advance, causes type Steel concrete to connect not tight, causes plated construction globality and supporting capacity to reduce.
Turn to target with construction assembling, solve the quick assembly problem of plate in construction, convenient between plate and beam column, safe, reliably the key technology difficult problem such as be connected, realize concrete slab batch production, modularization and standardization prefabricated, significant to improving steel work prefabricated construction technology.
Summary of the invention
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of periphery to establish shearing resistance muscle chan frame armored concrete slab, and described plate has simple structure, excellent performance and can be easy to realize the feature of steel work prefabricated construction.
In order to solve above technical problem, the utility model is achieved by the following technical programs.
The utility model provides a kind of periphery to establish shearing resistance muscle chan frame armored concrete slab, comprises concrete, steel mesh reinforcement and chan frame, and described chan frame is welded, is positioned at the outermost layer of concrete slab by channel-section steel; Described steel mesh reinforcement is by forming to spacing of reinforcement is evenly staggered in length and breadth, and is spaced set between vertical and horizontal reinforcing bar, and steel mesh reinforcement is as the skeleton of concrete slab in plate thickness direction layered arrangement, and steel mesh reinforcement surrounding is welded in chan frame; Described concrete slab also comprises shearing resistance muscle, and it is welded in chan frame, is positioned at chan frame mouth inside edge corresponding to steel mesh reinforcement top reinforcement end, and becomes 30～60 degree angles to be uniformly distributed with concrete slab plane.
Further, the spot welding of described shearing resistance muscle is connected to chan frame, and it becomes miter angle to be uniformly distributed with concrete slab plane.
Further, connecting by spot welding in intersection to uniform reinforcing bar in length and breadth in described steel mesh reinforcement, and steel mesh reinforcement is welded in the web inner edge of chan frame, divides upper and lower two-layer setting in concrete slab thickness direction.
Further, described concrete slab can continuous welding form continuous slab face by its peripheral chan frame.
Further, when concrete is that light weight concrete construction, steel mesh reinforcement are that channel-section steel in steel fabric sheet, chan frame is C shape light gauge cold-formed steel shape, shearing resistance muscle while being shearing resistance steel wire, concrete slab is now just filled-in panel or light-weight roof slab.
The principles of science of the present utility model is as follows:
A kind of periphery described in the utility model is established shearing resistance muscle chan frame armored concrete slab, is made up of concrete, double steel bar net, channel-section steel and shearing resistance muscle.In plate, surrounding channel-section steel plays dark beam effect, and the inner concrete of operative constraint, prevents that plate from ftractureing too early, has greatly improved anti-folding and the overall performance of plate; Be welded to the shearing resistance muscle of the channel-section steel mouth inside edge of the end reinforced correspondence of top mat, reduced the shearing slip between type Steel concrete soil contact face, postponed concrete slab crack and occurred and develop, be conducive to improve shearing resistance, the anti-seismic performance of plate; Levels is indulged transverse reinforcement, be connected to form steel mesh reinforcement in intersection by spot welding, and surrounding is welded on chan frame, guarantee the location of reinforcing bar, surrounding channel-section steel constraint steel mesh reinforcement after distortion, and extruded concrete, strengthen concrete perimeter constraint, reduce plank split development, improved plated construction globality and supporting capacity.
Compared with prior art, the utlity model has following technique effect:
1, the utility model concrete slab simple structure, easily manufactured, bending resistance, shearing resistance, anti-seismic performance excellence, and structural integrity is strong, and supporting capacity is high;
2, the utility model can be realized standardization, the batch production production of floor, and edges of boards channel-section steel can on-the-spotly pass through bolt or welding method and other girder steel, post, plate to be assembled, thereby realizes the quick assembling of plate, accelerates rate of progress of the construction.Significant to realizing steel building suitability for industrialized production target.
