Abstract

The utility model belongs to the field of concrete member prefabrication moulds, in particular to a rapid demoulding inner mould of a gap type drainage ditch; in order to solve the difficult problem of drawing of patterns of the interior sheathing of pouring gap formula escape canal usefulness at present. The inner mold is an arc-shaped template formed by rolling a whole piece of steel plate with elasticity, the arc ends at two sides of the arc-shaped template are connected with end plates, the distance between the end plates at two sides is consistent with the width of an opening gap of the gap type drainage ditch, and the height of the end plates is greater than the pouring thickness of the opening gap; the utility model provides a pair of quick drawing of patterns centre form in gap formula escape canal, it constitutes simply clearly, and its principle is that the appearance that has elastic steel plate is controlled with the bolt, thereby changes the effect that its overall dimension reached the drawing of patterns, fine solution low efficiency, the problem that should not tear open the mould.

Description

Quick drawing of patterns centre form in gap formula escape canal

Technical Field

The utility model belongs to precast concrete member mould field, concretely relates to quick drawing of patterns centre form in slot formula escape canal.

Background

The terrain of China is complex and various, the mountain area is large, with the rapid construction of the mountain expressway in recent years, the tunnel occupation ratio is higher and higher, the road surface drainage in the tunnel hole is usually the curb gap type drainage ditch 100, the structure of the gap type drainage ditch 100 is shown in figure 1, the gap type drainage ditch 100 comprises a flow channel 101 and an opening gap 102, and the appearance line shape of the gap type drainage ditch 100 is beautiful, smooth and smooth.

In the pouring forming work of the gap type drainage ditch, the key degree of the demoulding work as a ring ending is very important, but the inner templates of the gap type drainage ditch are all full-circle templates at present, the problems of difficult demoulding, complex operation and the like exist in the cylindrical inner template, and the mould structure is not easy to remove, so that the operation of workers is not facilitated, and a large amount of time is wasted.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem of the difficult drawing of patterns of inner formword of pouring gap formula escape canal usefulness at present.

The utility model provides a following technical scheme: the utility model provides a clearance formula escape canal fast demoulding centre form, centre form have elastic steel sheet by a whole and curl into arc template, the both sides arc end connection end plate of arc template, and the interval between the end plate of both sides conforms with the width in the opening gap in clearance formula escape canal, and the height of end plate is greater than the thickness of pouring in opening gap.

Furthermore, the part of the end plate higher than the pouring thickness of the opening gap is connected with the bolt, the end plate on one side is provided with a unthreaded hole, the end plate on the other side is provided with a screw hole, and the bolt penetrates through the unthreaded hole and is blocked at the screw hole thread of the end plate on one side and the screw hole thread of the end plate on the other side.

Further, a washer is fixed on the bolt, and the washer and the bolt head limit the end plates at two sides.

Compared with the prior art, the utility model has the advantages of:

the utility model provides a pair of quick drawing of patterns centre form in gap formula escape canal, it constitutes simply and clearly, and its principle is that the appearance that has elastic steel plate is controlled with the bolt, thereby changes the effect that its overall dimension reached the drawing of patterns, fine solution low efficiency, the problem that should not tear the mould open.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the description below are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

As shown in fig. 2 and 3: the utility model provides a gap formula escape canal fast demoulding centre form, centre form have elastic steel sheet batching arc template 1 by a whole, and end plate 2 is connected to the both sides arc end of arc template 1, and the interval between the both sides end plate 2 conforms with the width in the opening gap in gap formula escape canal, and the height of end plate 2 is greater than the thickness of pouring in opening gap. Combining an inner mold and an outer mold according to the positions shown in figure 2 (the inner mold is supported by a concrete cushion block), binding reinforcing bars of a gap type drainage ditch, installing end templates at the front and the back of the inner mold and the outer mold to form a closed mold cavity (reserved grouting openings), removing the outer mold and the end templates after concrete is solidified, applying force to two end plates 2 from two sides, gathering the whole arc-shaped template 1 to the center, reducing the inner diameter of the whole arc-shaped template 1, realizing demolding, and taking the inner mold out from one side.

The arc-shaped template 1 is made of a 301 high-elasticity stainless steel plate, is coiled into an arc shape, is shaped and can be restored by being compressed towards the center.

In order to apply thrust to the arc-shaped template 1, the end plate 2 is higher than the part of the connecting bolt 3 with the pouring thickness of the opening gap, the end plate 2 on one side is provided with a unthreaded hole, the end plate 2 on the other side is provided with a screw hole, the bolt 3 penetrates through the unthreaded hole, the bolt head is stopped at the screw holes of the end plate 2 on one side and the end plate 2 on the other side in a threaded manner, and the end plate on one side is pushed to approach to the other side along with the rotation of the bolt 3.

When concrete is poured, the arc-shaped template 1 is folded under the pressure of the concrete, the end plates 2 on the two sides are close to each other, a gasket 4 is fixed on the bolt 3 for supporting the end plates 2 on the two sides, and the gasket 4 and the bolt head limit the end plates 2 on the two sides.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
