Abstract

The utility model relates to a docking interface sealing structure for a concrete pipe pile mould. The structure comprises a concrete pipe pile forming die, and a sealing strip is arranged on the spigot of the upper die or lower die of the concrete pipe pile forming die. The structure has the advantages that the sealing combination between the upper die and the lower die of the docking interface sealing structure for the concrete pipe pile forming die is radically ensured, the defect that the concrete slurry overflows is avoided, and the forming quality of the concrete pipe pile and the cooperation life of the concrete pipe pile mould are guaranteed.

Description

Concrete pile tube mould mating interface hermetically-sealed construction

Technical field

The utility model relates to a kind of concrete pile tube mould mating interface hermetically-sealed construction, belongs to concrete pile tube mould mating interface and makes the field.

Background technology

In the existing concrete pile tube mould mating interface hermetically-sealed construction, the butt joint seam of its upper and lower mould is the rigidity butt joint.Its weak point: because the concrete pile tube is in the process of making, concrete wine inevitably falls thereon, on the butt joint seam of counterdie, cause, the counterdie closure is not tight, therefore in the manufacturing process of concrete pile tube, the concrete that is positioned at shaping mold cavity is under the effect of high speed centrifugation power, its concrete slurries are inevitably from last, overflow in the seam of counterdie butt joint, not only cause the waste of concrete slurry, and directly have influence on the forming quality of pile tube, simultaneously owing to overflow to, the concrete slurry of counterdie butt joint stop portion, can condense thereon again, cause in the concrete pile tube mould mating interface hermetically-sealed construction on, the overfall of counterdie butt joint seam is increasing, so that can't normally use.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design a kind of concrete pile tube mould mating interface hermetically-sealed construction that can improve the upper and lower mould sealing property of concrete pile tube effectively.

Design: in order to realize above-mentioned purpose of design.The utility model is on the basis of existing concrete pile tube mould mating interface hermetically-sealed construction; on the seam of the patrix of concrete pile tube mould mating interface or counterdie, a sealing strip is set; the sealing bar can stop the slurries in the concrete pile tube forming cavity to overflow effectively; thereby avoid the weak point in the background technology, guarantee the service life of the forming quality and the concrete pile tube mould mating interface of concrete pile tube.Its technical scheme: concrete pile tube mould mating interface hermetically-sealed construction, it comprises concrete pile tube shaping mould, is equipped with sealing strip on the patrix of concrete pile tube shaping mould or the seam of counterdie.

The utility model is compared with background technology, the setting of concrete pile tube mould mating interface hermetically-sealed construction, fundamentally guaranteed the sealing combination of the upper and lower intermode of concrete pile tube mould, the defective of having avoided the concrete slurries to overflow, the service life of having guaranteed the forming quality and the concrete pile tube shaping dies of concrete pile tube.

Fig. 2 is the schematic diagram of concrete pile tube counterdie plan structure.

The specific embodiment

Embodiment 1: with reference to attached Fig. 1 and 2.Concrete pile tube mould mating interface hermetically-sealed construction, it comprises concrete pile tube shaping mould 1, concrete pile tube shaping mould 1 is a prior art, is not described herein at this.Be equipped with sealing strip 2 on the patrix of concrete pile tube shaping mould or the seam of counterdie, sealing strip 2 and seam boss 3 are flat or be lower than seam boss 3.

What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.

Claims

1, a kind of concrete pile tube mould mating interface hermetically-sealed construction, it comprises concrete pile tube shaping mould, it is characterized in that: be equipped with sealing strip on the patrix of concrete pile tube shaping mould or the seam of counterdie.

2, concrete pile tube mould mating interface hermetically-sealed construction according to claim 1 is characterized in that: sealing strip and seam boss are flat or be lower than the seam boss.
