Because rubber bottom plug length is shorter, and is relatively poor to the restraint of grout bellows, grout bellows free end overlength, at bent cap steel reinforcement cage hoist and mount and concrete placement in-process, the position and the straightness that hangs down at grout bellows top can change, and serious person can influence the installation of later stage prefabricated bent cap.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an avoid the weak point that above-mentioned prior art exists, provide a prefabricated bent cap grout bellows positioner, can control the position of grout bellows more effectively, hang down straightness, save the spacer bar quantity, reduce reinforcing bar installation work load for construction speed.

The scheme of the utility model is realized like this:

a prefabricated bent cap grouting corrugated pipe positioning device comprises rubber plugs, a steel sleeve and a bolt, wherein the rubber plugs are coaxially mounted at the upper end part and the lower end part of the steel sleeve respectively, the two rubber plugs are connected with the steel sleeve through the bolt which is coaxially penetrated, a top plate is arranged on the upper end face of the rubber plug at the upper part, and the end part of the bolt is coaxially connected with a nut in a threaded manner;

the steel sleeve consists of a steel pipe and a fixing plate, and the fixing plate with an annular structure is fixedly installed at two end parts of the steel pipe respectively;

the diameter of roof, fixed plate and rubber buffer equals.

Moreover, a gasket is arranged at the inner end of the nut.

The utility model has the advantages that:

1. this positioner is provided with two-layer rubber buffer to add between the rubber buffer and establish the steel sleeve, make the about end extension in grout bellows bottom, increased the stability and the fastness of grout bellows, be convenient for control the straightness that hangs down of grout bellows.

2. Rubber buffer, steel casing pipe, roof among this positioner are dismantled conveniently to can adjust steel casing pipe length according to grout bellows length, applicable in the fixed of the grout sleeve of different models.

3. The utility model has the advantages of simple structure and scientific and reasonable design, convenient operation has reduced positioning bar welded work load, can effectively avoid positioning bar welding burn phenomenon of grout bellows, has the value of extensive popularization and application.

Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.

A prefabricated bent cap grouting corrugated pipe positioning device comprises rubber plugs 2, a steel sleeve 3 and bolts 4, wherein the rubber plugs 2 are respectively and coaxially mounted at the upper end part and the lower end part of the steel sleeve 3, the two rubber plugs 2 are connected with the steel sleeve 3 through the bolts 4 which are coaxially penetrated, a top plate 1 is arranged on the upper end surface of the rubber plug 2 positioned at the upper part, and the end parts of the bolts are coaxially connected with nuts 8 in a threaded manner;

the structure of the steel sleeve 3 is shown in fig. 2 and comprises a steel pipe 3B and a fixing plate 3A, and the fixing plate 3A with an annular structure is fixedly installed at two end parts of the steel pipe 3B respectively;

the diameters of the fixing plate 3A, the top plate 1 and the rubber plug 2 are equal.

In this embodiment, a gasket 7 is disposed at the inner end of the nut.

The processing method of the utility model is as follows:

1. a hole is formed in the base steel plate 6, the position of the hole is consistent with the central position of the grouting corrugated pipe 5, and the aperture is slightly larger than the diameter of the bolt 4; the two rubber plugs are opened at the center, so that the bolt 4 can be smoothly inserted; the center of the top plate 1 is provided with a hole, and all the holes are coaxial with the bolts 4;

2. sleeving the top plate 1 into the top of the bolt 4, and then installing the top rubber plug 2 to enable the top of the top rubber plug 2 to be tightly attached to the top plate 1;
