Description

The grid type scaffold floor

Technical field

The utility model relates to a kind of the construction with the assembly of scaffold, relates in particular to a kind of grid type scaffold floor.

Background technology

Existing scaffold floor mainly contains bamboo wood scaffold floor, steel mesh scaffold floor, steel plate scaffold floor etc., and wherein the manufacturing cost of bamboo wood scaffold floor, steel mesh scaffold floor is lower, but its application life is shorter, durability is relatively poor, the cost of steel plate scaffold floor is then higher, and is also very heavy, and it is not too convenient that carrying is got up.

The utility model content

The purpose of this utility model is to provide a kind of long service life, and weight is lighter, the grid type scaffold floor that cost is lower.

Grid type scaffold floor of the present utility model, comprise two edge-beams that are arranged in parallel, be provided with at least one middle girder between two edge-beams, the two ends of two edge-beams and each middle girder link to each other with a curb girder respectively, the inboard of the upper surface of two edge-beams has a step, and between the step of two edge-beams and the upper surface of each described middle girder longitudinally or laterally is provided with a plurality of junction plates.

Grid type scaffold floor of the present utility model, wherein the cross section of two described curb girders is [a shape, the two ends of two described edge-beams and each described middle girder are weldingly fixed on [in the shape groove of two curb girders respectively, two edge-beams and in the middle of each girder the lower surface longitudinally or transverse weld a plurality of base plates are arranged, the two ends of the lateral surface of two described curb girders are respectively equipped with the overlap joint hook.

Grid type scaffold floor of the present utility model, wherein each described in the middle of the cross section of girder be ∩ shape or

Shape or

Shape, the cross section of two described edge-beams (4) is

Shape, the upper surface of described junction plate is concordant with the upper surface of two edge-beams.

Grid type scaffold floor of the present utility model, wherein two described edge-beams, each described middle girder and two described curb girders adopt the thick steel plate punching press of 1-3mm to make respectively.

Grid type scaffold floor of the present utility model, wherein the gib head of each described overlap joint hook is

Arc, each overlap joint hook adopts welding to link to each other with described curb girder, and the gap between two adjacent described junction plates is 20-40mm.

Grid type scaffold floor of the present utility model, the quantity of wherein said middle girder are 1-3, and the quantity of described base plate is 2-6.

Grid type scaffold floor of the present utility model, owing to be provided with at least one middle girder between two edge-beam, the two ends of two edge-beams and each middle girder link to each other with a curb girder respectively, the inboard of the upper surface of two edge-beams has a step, between the step of two edge-beams and the upper surface of each middle girder longitudinally is provided with a plurality of junction plates, so grid type scaffold floor of the present utility model has long service life, weight is lighter, the characteristics that cost is lower.

Other details of grid type scaffold floor of the present utility model and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, grid type scaffold floor of the present utility model comprises being provided with 2 middle girders 3 between 4, two edge-beams 4 of two edge-beams that are arranged in parallel that the quantity of middle girder 3 also can be 1 or 3.The two ends of two edge-beams 4 and each middle girder 3 link to each other with a curb girder 2 respectively, and the inboard of the upper surface of two edge-beams 4 has a step, and the cross section of step is Shape, two edge-beams 4 Between the shape step and the upper surface of each middle girder 3 longitudinally is provided with a plurality of junction plates 5, or the gap that the edge laterally is provided with between 5, two adjacent junction plates 5 of a plurality of junction plates is 20-40mm.

As Fig. 4, Fig. 5 and shown in Figure 7, the cross section of two described curb girders 2 is [a shape, the two ends of two edge-beams 4 and each middle girder 3 are weldingly fixed on [in the shape groove of two curb girders 2 respectively, longitudinally or along transverse weld there are 2 base plates 6 lower surface of two edge-beams 4 and each middle girder 3, and the quantity of base plate 6 also can be 2-6.The two ends of the lateral surface of two curb girders 2 are respectively equipped with overlap joint hook 1, and the gib head of each overlap joint hook 1 is

Arc can be overlapped on the scaffold easily, and each overlap joint hook 1 adopts welding to link to each other with curb girder 2.

As Fig. 4, Fig. 5 and shown in Figure 6, in the middle of each the cross section of girder 3 be ∩ shape or
