Abstract
The invention discloses a bearing floor supporting plate, specifically discloses a bi-direction mixed cross reinforcing steel bar truss self-bearing floor supporting plate and a manufacture method, belonging to the floor panel technology field of building project; specifically applied to floor supporting plate for steel structure building. The bi-direction mixed cross reinforcing steel bar truss self-bearing floor supporting plate comprises a triangle section reinforcing steel bar truss floor supporting plate and a plane reinforcing steel bar truss arranged in cross direction, a plane reinforcing steel bar truss connected to the triangle section reinforcing steel bar truss is fixedly arranged in the other direction, which is vertical to the triangle section reinforcing steel bar truss for forming the vertical floor supporting plate, the triangle section reinforcing steel bar truss is in one direction while the lane reinforcing steel bar truss is in the other direction, which is vertical to triangle section reinforcing steel bar truss. The reinforcing steel bar truss in different direction is forced for deforming and bearing the construction load for raising the reliability of the floor supporting plate. For cooperation work of the triangle section reinforcing steel bar truss and the lane reinforcing steel bar truss, the thickness, weight and cost of the self-bearing floor supporting plate can be effectively reduced and the indoor height of the building is saved.
Description
Technical field
The present invention relates to a kind of load-bearing floor support plate, specifically a kind of two-way mixing cross wise reinforcement truss self-supporting floor support plate, belong to construction work floor plate technical field.Be mainly used in the room floor support plate of aspect ratio between 1-2.Be specially adapted to the floor support plate of steel house.
Background technology
At present, in construction steel structure, floor support plate generally adopts steel bar truss floor support plate system, steel bar truss floor support plate system is by the reinforcing bar of 5 in floor, wherein 2 web member reinforcing bars 3,1 wind up reinforcing bar 1 and 2 lower edge reinforcing bars 2, constitutionally stable English truss is formed by operations such as automatic moulding, alternating-current resistance spot welding, on-line checkingi and automatic shearings in factory, then by steel bar girder and zinc-plated profiled sheet resistance spot welding all-in-one-piece steel work floor support plate product.It is relative to traditional Bars In Poured Concrete Slab, and truss force modes can provide larger floor support plate rigidity, can greatly reduce or without the need to by construction temporary support.Due to without the need to scaffold and a die process, efficiency of construction has certain improvement and raising really.Its structure as shown in Figure 1.
But this traditional steel bar truss floor support plate system is under construction operating mode, a direction is only had to have steel bar girder, for meeting the distortion and fragmentation that unlikely generation is excessive under working load and water-bearing concreae Gravitative Loads, its steel bar girder height is general larger, after generally having built concrete, thickness can reach even more than 150mm, thus increase dead load because floor support plate is too thick and occupies Indoor environment clear height, result also in the increase of cost simultaneously, also limit its application in residential project.
Summary of the invention
For overcoming the too thick shortcoming of traditional steel bar truss floor support plate system floor support plate, the invention provides a kind of two-way mixing cross wise reinforcement truss self-supporting floor support plate and manufacture method, on traditional steel bar truss floor support plate basis, in another one direction, plane steel bar girder is also set, thus form one to being triangular cross-section steel bar girder, one to the floor support plate system of the two-way load-bearing for plane steel bar girder, effectively can reduce the height of steel bar girder, thus reduce the thickness of floor support plate, reach the object of saving Indoor environment clear height, reducing floor support plate deadweight and reduction cost.
The technical scheme that technical solution problem of the present invention adopts is: a kind of two-way mixing cross wise reinforcement truss self-supporting floor support plate, the plane steel bar girder comprising triangular cross-section steel bar truss floor support plate and arrange with its orthogonal direction, be fixedly installed the plane steel bar girder be fixed together with triangular cross-section steel bar girder in another direction vertical with triangular cross-section steel bar girder, thus formation is hung down mutually, one of friendship to being triangular cross-section steel bar girder, another floor support plate to the two-way load-bearing for plane steel bar girder.
Described triangular cross-section steel bar truss floor support plate comprises by two lower edge reinforcing bars, is positioned at of two lower edge reinforcing bar middle upper parts and winds up reinforcing bar and the bending web member reinforcing bar of two triangularity waves; Two web member reinforcing bars are symmetrical arranged and are welded on lower edge reinforcing bar respectively and wind up between reinforcing bar.
Described plane steel bar girder comprises a lower edge reinforcing bar, wind up reinforcing bar and a web member reinforcing bar being arranged on lower edge reinforcing bar and winding up between reinforcing bar, and leaves installation gap with two lower edge reinforcing bar infalls of triangular cross-section steel bar girder on its lower edge reinforcing bar; The winding up of described plane steel bar girder makes plane steel bar girder be positioned at vertical plane together with aliging with the node that winds up of triangle steel bar girder and being welded and fixed.
The preparation method of above-mentioned two-way mixing cross wise reinforcement truss self-supporting floor support plate, concrete steps are:
(1) adopt resistance welding shaping according to the spacing designed and the thick galvanized steel plain sheet of 0.5-1mm in factory triangular cross-section steel bar girder, be common triangular cross-section steel bar truss floor support plate;
(2) then by the machine-shaping of plane steel bar girder and at its lower edge outflow breach, notch size 2-4mm larger than triangle steel bar girder two lower edge reinforcing bar crust sizes;
(3) notched plane steel bar girder snapped in triangular cross-section steel bar girder and plane steel bar girder lower edge is alignd with the horizontal web member of triangular cross-section steel bar girder, then welding, two-way mixing cross wise reinforcement truss self-supporting floor support plate can be produced.
Such scheme is on traditional steel bar truss floor support plate basis (depth of truss is less), in construction and installation process, plane steel bar girder is set at scene, another one direction, thus form one to being triangular cross-section steel bar girder, one to the floor support plate system of the two-way load-bearing for plane steel bar girder, the steel bar girder cooperative bearing of both direction and cooperative transformation, the effect of shared working load, improves the reliability of floor support plate.The triangle steel bar girder and the collaborative work of plane steel bar girder handed over owing to mutually hanging down, effectively reduce self-supporting floor support plate thickness, deadweight, cost and saved Indoor environment clear height.
The invention has the beneficial effects as follows, can ensure that it is under the prerequisite meeting normal construction under working load effect, reduce the thickness of floor support plate, reach the object of saving Indoor environment clear height, reducing floor support plate deadweight and reduction cost, be specially adapted to the floor support plate of this steel house.
