Abstract
The invention belongs to the field of building moulding plates, and discloses a cold-pressed coiled rib steel moulding plate. The cold-pressed coiled rib steel moulding plate comprises a steel bottom plate which is positioned at the top end, wherein the steel bottom plate is rectangular; a side rib plate is arranged on each of the left side and the right side of the steel bottom plate; an end rib plate is arranged on each of the front side and the rear side of the steel bottom plate; connecting holes are formed in each side rib plate and each end rib plate; the side rib plates and the steel bottom plate adopt a cold-pressed rolled integrated structure; a punching groove is formed in each side rib plate. The cold-pressed coiled rib steel moulding plate is high in strength, high in deformation resistance, high in structural precision, easy to manufacture and low in production cost.
Description
Technical field
The present invention relates to one to cold pressing volume rib steel template, belong to construction formwork field.
Background technology
Traditional template forms primarily of flitch and bamboo slab rubber, and the dismounting time needs to consider the intensity of concrete curing age, concrete members and the span of beam and plate, then removes according to regulation and stipulation.Needed for form removable, the cycle is long, and template expense is large.
In order to save bamboo clappers and timber, improving the number of turnover of concrete blinding, having utilized steel parts or all having replaced bamboo plank.When the span of concrete blinding is larger, just need polylith template to link together, centre connects with early dismantling head and keel.
The structure of existing early dismantling head and keel or other connection templates is shaped steel and is welded, and this steel template structure is coarse, and the welding deformation of steel form is large, and intensity is not high, and non-deformability is poor.
Summary of the invention
It is that in steel form, welding deformation is large that the present invention solves, the technical problem of non-deformability difference.
Technical scheme of the present invention is, there is provided one to cold pressing and roll up rib steel template, comprise the steel sole plate being positioned at top, described steel sole plate is rectangle, the left and right sides of steel sole plate is equipped with limit floor, and both sides, front and back are equipped with end rib plate, and limit floor and end rib plate are equipped with connecting hole, described limit floor and steel sole plate are rolling integrated formed structure of colding pressing, and limit floor upper punch is pressed with groove.
Further, described end rib plate welds with steel sole plate.
Further, described limit floor, end rib plate are vertical between two with steel sole plate.
Further, the connecting hole on the floor of described limit is positioned on groove.
Further, described groove is dovetail groove.
Further, described limit floor and steel sole plate are obtained by steel plate crimping.
Further, the floor cold stamping of described limit is bent with groove.
Steel form provided by the invention is that manufacturing process is as follows: make steel plate produce plastic strain by cold stamping, form steel sole plate, limit floor and groove, then punch on limit floor and end rib plate respectively, form connecting hole, finally end rib plate is welded with steel sole plate, limit floor, form described steel form.When on the floor of limit, connecting hole is located on groove, the diameter of connecting hole should be less than the width of groove bottom land.
Steel form entirety provided by the invention is the rectangular box like structure without bottom surface, end face is steel sole plate, four sides are respectively two right, a pair side is limit floor, another is to being end rib plate, when limit floor is longer, can weld between two blocks of end rib plates parallel with end rib plate in floor as the use of reinforcing rib.The steel form of this rectangular box like structure is not yielding, is convenient to be connected with adjacent template.
Steel form provided by the invention forms a stencil plane by connecting hole and other form assemblies, concreting on stencil plane.Support bar can be connected, for support bar steel form and concrete in the below of described steel form.
Control to make steel form convenient formation provided by the invention, make to strike out right angle between limit floor and steel sole plate, the groove of punching press on the floor of limit can improve the structural strength of steel form, hardness and non-deformability widely, make steel form when being subject to impacting, be not easy to produce deformation, yield strength improves widely.On the floor of limit, the groove of punching press particularly enhances resistance to compression and the rupture strength of perpendicular grooves in-plane; By groove design in echelon groove can avoid steel plate by during punching press because angle is excessive and produce Plate break.Steel plate crimping obtains limit floor, and limit floor carries out the dovetail groove of cold stamping bending again, greatly enhances resistance to compression and the anti-bending strength of this template.
The invention has the beneficial effects as follows, described in the cold pressing intensity of volume rib steel template high, non-deformability is strong, and structure precision is high, and make simple, cost of production is low.
Accompanying drawing explanation
Fig. 1 represents the schematic perspective view of volume rib steel template of colding pressing provided by the invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
One block of rectangular steel plate is carried out punching press crimping along its length, one-body molded, obtain steel sole plate 1, limit floor 2, then cold stamping is bent with trapezoidal groove 4 on limit floor 2; Again in the bottom land punching of trapezoidal groove 4, obtain connecting hole 5; The shaped steel of connecting hole 5 separately punching is had to weld to obtain colding pressing with steel sole plate 1, limit floor 2 as end rib plate 3 and roll up rib steel template.Described volume rib steel template of colding pressing greatly reduces welding deformation, and structure precision is high, and intensity is high, and non-deformability is strong, and make simple, cost of production is low.
