Description

Building steel plastic formwork

The invention belongs to a kind of mould of building operations.

In present building operations, what generally use is the template of being made by metal sheet.Metal form is welded with four side plate, rectangle metal sheets that have connecting hole in the surrounding of metal sheet perpendicular to the rectangle metal sheet and is constituted at the stiffener of the one side welding vertical and horizontal that are welded with side plate by the square metal sheet of a block length.Its smooth surface of all-metal building operations template, the surface roughness of being poured into a mould member is little, and adhesive power is little, is not easy to finishing; Because of template is that metal material is made, cause steel big with the steel consumption, be not easy to reduce the expense of construction, also cause the waste of steel simultaneously; The insulation that the coefficient of thermal conductivity of invar pallet is big, be unfavorable for pouring piece with solidify.

It is little to the purpose of this invention is to provide a kind of steel consumption, the steel mold plate of good heat insulating.

Building operations steel mold plate is to be made of the framework of metal sheet making and the plastic plate of injection mo(u)lding.Below by drawings and Examples in detail the present invention is described in detail.

3 employing steel plate machine-shapings of swallow-tail form reinforcement gusset and side plate 2, side plate 9 are with length, the dovetail groove Y that is processed into ₂Swallow-tail form projection 11 Fig. 2 on Fig. 6, Fig. 7 and the plastic plate 8, Fig. 3 Figure 10, Figure 11 match.Swallow-tail form is strengthened the back of gusset 3 and is welded reinforcement gusset 5 Fig. 6, Fig. 7 of a block length bar shaped.

Vertical junction plate 1,7 is the end plate of template framework, and the hole K that is connected with adjacent forms is arranged on the long limit of unequal-sided vertical junction plate 1,7 ₃, K ₄Fig. 1, the vertical junction plate 4,6 of inequilateral is welded in the template framework.

The horizontal side plate 2 of F shape, the horizontal side plate 9 of F shape, unequal-sided vertical junction plate 1, vertical junction plate 4, vertical junction plate 6, vertical junction plate 7, swallow-tail form are strengthened the reinforcement gusset 5 of gusset 3, strip by the integrant steel mold plate framework in welding back.

Plastic formwork 8 adopts thermoplastic injection molding.Plastic formwork 8 is rectangle diagram 1, Figure 10, and the front design of template 8 has the circular protrusions T that increases the pouring piece surface roughness ₁Respectively there is a groove C to lower recess in the front of template 8 edge on long limit up and down ₁, C ₂Figure 10, Figure 11.Groove C ₁, C ₂The degree of depth equal the strip metal plate T of F shape side plate 2,9 ₄Thickness.There is a horizontal swallow-tail form projection 11 at the middle part, the back side of template 8.
