Abstract

The utility model relates to a producing mould for prestress concrete pipe, consisting of two semicircular cylinders, flanges, a bearing, a running circle and a faucet body; wherein, the two semicircular cylinders are fixed together through a bolt. The utility model is characterized in that two bearings are welded at the positions which are symmetrical with the cylinders, the running circle is fixed at the bearing; two semicircular flanges are respectively fixed at the two end faces of the cylinder, and a round faucet body is fixed at the flange. When making, the die runs up through the friction between the running circle and the wheels which operate with a high speed, and the prestress concrete pipe is made by the centrifugal force which is caused by the high-speed operation of the die.

Description

The making mould of prestressed concrete pipe

The utility model relates to a kind of mould of making pipe fitting, refers more particularly to a kind of mould of making prestressed concrete pipe.

In the supply and drain water system in city, pipe fitting is widely used, currently used pipe fitting generally all is steel pipe and prestressed concrete pipe, but because the steel pipe corrosion resistance is not high, and installation is comparatively complicated, price is higher, so all be to adopt prestressed concrete pipe now mostly in the supply and drain water system in city, the internal diameter maximum of prestressed concrete pipe can reach 6.4m in the world now.On Chinese domestic market, prestressed concrete pipe all is to adopt to make by hand, and have following defective: the pipe fitting density of making is inhomogeneous, easy damaged pipe fitting when the demoulding, and also make efficiency is lower.

The purpose of this utility model just provides a kind of mould of making prestressed concrete pipe, adopts the machinery production prestressed concrete pipe, makes the density of making pipe fitting even, is convenient in demoulding, and improves the efficient of making pipe fitting.

The purpose of this utility model is achieved in that the making mould of this prestressed concrete pipe is by two semicircle cylindrical shells, bearing, run circle, flange and socket body are formed, several " well " fonts that have been welded uniformly on two semicircle cylindrical shells are strengthened gusset, two barrier parts by several bolting together, it is characterized in that: on symmetrical position, shape cylindrical shell two ends, two and half gardens, respectively be welded with a semicircular bearing, respectively be welded with a semicircular flange at the two ends of cylindrical shell, the socket body that a circle is arranged by several bolting on the flange, be fixed with the race circle by spiral shell on described bearing, several holes has equably distributed on described socket body.In the process of making prestressed concrete pipe, at first reinforcing bar is fixed in the hole of socket body, mould is placed on the wheel that runs up then, rotate at a high speed by running the drive entire die that rubs between circle and the wheel, add concrete in the mould then, make pipe of concrete by the centrifugal force of mould.

The utility model compared with prior art has following advantage: the pipe of concrete compactness of making not only evenly but also high, was convenient in demoulding, make efficiency is higher.

Below in conjunction with accompanying drawing the utility model is done further narration.

Fig. 1 is the making mould structure schematic diagram of prestressed concrete pipe described in the utility model.

1. socket body 2. flanges 3. tunnel enclose 4. bearings, 5. reinforcements

6. cylindrical shell 7. bolts 8. holes

As can be seen from Figure 1, the making mould of prestressed concrete pipe described in the utility model is by two semicircle cylindrical shells 6, four semicircle bearings 4 and flange 2, the socket body 1 of two circles and race circle 3 are formed, two and half garden shape cylindrical shells 6 are fixed together by equally distributed bolt 7, on described cylindrical shell 6, be welded with several " well " font reinforcements 5 equably, it is characterized in that: the end face at two semicircle cylindrical shells 6 respectively is welded with a semicircular flange 2, be fixed with a circular socket body 1 on described flange 2, several holes 8 equably distributes on the circumference of described socket body 1.In the process of making prestressed concrete pipe, at first two semicircle cylindrical shells 6 are fixed together by bolt 7, to run circle 3 is fixed on the bearing 4, and socket body 1 is fixed on the flange 2, then high tensile wire is fixed in the hole 8 of socket body 1, and mould is installed on one group of wheel that runs up, drive the mold high speed running by the friction of running between circle 3 and the wheel, in mould, add concrete again, centrifugal force by the mold high speed rotation is made body, and the body density of making is high and even like this.

Claims (2)

1. the making mould of prestressed concrete pipe is made up of the socket body (1) and the race circle (3) of two semicircle cylindrical shells (6), four semicircle bearings (4) and flange (2), two circles, two semicircle cylindrical shells (6) are fixed together by equally distributed bolt (7), be welded with several " well " font reinforcements (5) equably on described cylindrical shell (6), it is characterized in that: the end face at two semicircle cylindrical shells (6) respectively is welded with a semicircular flange (2); On described flange (2), respectively be fixed with a circular socket body (1).

2. the making mould of pipe of concrete according to claim 1, it is characterized in that: several apertures (8) equably distribute on the circumference on the described socket body (1).
