Abstract

The utility model relates to a mould which is used for a forming machine for a concrete member, comprising a U-shaped inner mould which is arranged on a mould seat plate. A U-shaped inner chamber which has a certain height is formed by the inner mould and an outer mould, and the outer mould is provided with a ventilating device. The utility model can produce the high solid concrete members, and the compression-proof performance and the fold-proof performance of the high solid concrete members are increased further.

Description

A kind of U pattern tool

The utility model relates to a kind of technical field of mold, especially is fit to be installed in employed mould on the forming machine for concrete building unit.

The U pattern tool that uses on the available coagulation soil molding component machine, shown in China Patent No. 97233461.0 " a kind of mould ", though solved the trouble of concrete component in construction and the leakage problems of joining place that the half U type mould is produced, but because dies cavity is the no permeability type of sealing, gas in process in the concrete can't in time be discharged, reduce the packing of concrete component, caused the resistance to compression of member, fracture resistance relatively low.

The purpose of this utility model provides a kind of mould of producing the higher U type concrete component of packing.

The utility model includes the die holder plate, and U type internal mold is installed on the die holder plate, correspondingly with internal mold is movably installed with two symmetrical external molds, and two external molds are to have locking nut fixedly connected, and it is characterized in that has gas permeable devices on the external mold.This gas permeable devices is by the several rows of little air-vent that is evenly distributed on the external mold, and this air-vent communicates with inner chamber.

The utility model not only constitutes the inner chamber of all U shape structure, and on external mold, have many air-vents that communicate with inner chamber, this can emit the gas in the concrete in the tool member process in time by air-vent, thereby improve the packing of concrete component, make produce the member resistance to compression, fracture resistance is good.

Accompanying drawing shows embodiment of the present utility model, wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is Figure 1A-A longitudinal sectional view;

Fig. 3 is the vertical view among Fig. 1;

Fig. 4 is the A-A revolved view;

The utility model includes die holder plate (10), U type internal mold (2) is installed on die holder plate (10), internal mold (2) is for having the U type of certain altitude, correspondingly with internal mold (2) be connected with two symmetrical external molds (3) by the turning point (4) that is installed in top, U type two ends, it is fixedly connected by locking nut (6) that the external mold of two symmetries (3) opens and closes end, internal mold this moment (2) constitutes U type inner chamber (8) with external mold (3), also be evenly distributed with several rows of little air-vent (1) on external mold (3), these air-vents (1) communicate with inner chamber (8).

During use, earlier mould is installed on the make-up machine by alignment pin (9), external mold (3) with two symmetries, fixedly connected good by locking nut (6), U type inner chamber (8) by external mold (3) and internal mold (2) constitute adds concrete to inner chamber (8), by the electromagnetic shaker that is installed in mould one side (7) vibrations pressurization, gas in the concrete emits by several rows of little air-vent (1) simultaneously, makes it all to fill up.When taking out concrete component, need earlier locking nut to be turned on, hold the handle (5) that is installed in external mold (3) both sides, two external molds (3) are rotated to both sides respectively by turning point (4),, take out member then and get final product to taking out the member desired position.

Claims

1. U pattern tool, include die holder plate (10), on die holder plate (10), be installed with U type internal mold (2), corresponding two the symmetrical external molds (3) that are movably installed with internal mold (2), two external molds (3) are fixedly connected by locking nut (6), internal mold this moment (2) constitutes U type inner chamber (8) with external mold (3), it is characterized in that on the external mold (3) gas permeable devices being arranged.

2. U pattern tool according to claim 1 is characterized in that described gas permeable devices is made of the several rows of little air-vent (1) that is evenly distributed on the external mold (3), and this air-vent (1) communicates with inner chamber (8).
