Abstract

A dual-purpose vertical steel mould for manufacturing prestressed concrete cylinder pipes relates to an improved vertical vibration steel mould structure for manufacturing the prestressed concrete cylinder pipes (PCCP) and is multipurpose. The dual-purpose vertical steel mould comprises a cylindrical inner mould, a cylindrical outer mould, an annular bottom mould, an annular top mould and a base, the base is fixedly arranged below the inner mould and the outer mould, and the bottom mould is arranged on the upper portion of the base between the inner mould and the outer mould. The base is arranged between the inner mould and the outer mould, the bottom mould is modified into a height-adjustable structure, so that the height of the bottom mould between the inner mould and the outer mould is adjustable. Therefore, the vertical steel mould is dual-purpose and even multipurpose. In order to prevent leakage of concrete during application, liquid sealing structures are arranged between the movable bottom mould and the inner mould, as well as between the movable bottom mould and the outer mould. Two kinds of the PCCPs which are in different height (length), same in size of the bell and spigot joint working surface and the slot working surface and same in the thickness and the size of pipe cores can be produced by one dual-purpose vertical steel mould.

Description

Make the dual-purpose vertical punching block of Prestressed concrete cylinder pipe

Technical field

The utility model relates to the improvement to the vertical vibrating structure of steel die of making Prestressed concrete cylinder pipe (PCCP).

Background technology

It is to be used for being shaped the requisite mould of prestressed pipe for a PCCP vertical vibrating punching block.Originally punching block is to customize punching block by caliber sized, interface size, body length, even if identical caliber, identical interface size as long as the body height dimension is different, also will be made the mould of two cover differing heights.Cause user's production input cost higher like this.

The utility model content

The utility model provides a kind of vertical punching block that can realize the making Prestressed concrete cylinder pipe of one module multiple usages to above problem.

The technical scheme of the utility model is: comprise the internal mold of tubular, the external mold of tubular, the bed die of annular and the backform of annular, also comprise the base that is fixedly installed on said inside and outside mould bottom; Said bed die is arranged on the base top between the inside and outside mould.

Between bed die and base, be provided with the circular Connection Block that is used to regulate the bed die height, said Connection Block end face and said bed die bottom surface removably connect, and the bottom surface of said Connection Block and the end face of said base removably connect.

Be provided with hermetically-sealed construction one between the interior annular face of said bed die and the outer surface of said internal mold; Be provided with hermetically-sealed construction two between the exterior annular face of said bed die and the inner surface of said external mold.

The utility model has changed the present situation of a mould one usefulness in the prior art.Between inside and outside mould, base is set, changes bed die the structure of adjustable height form into, make that the bed die between the inside and outside mould has had adjustable for height function.Like this, a mold just can realize that a mould is dual-purpose, even one module multiple usages.The utility model for preventing the concrete leakage, is provided with liquid sealing structure between movable bed die and inside and outside mould in application.The utility model can be adjusted according to actual needs.One mold can produce two kinds (such as 5 ~ 6m) two kinds different high (length) spend and hold, socket working face size and the measure-alike PCCP body of die thickness.

Fig. 2 is the structural representation after the utility model changes height,

Fig. 3 is an A-A cutaway view among Fig. 2,

Fig. 4 is a B place partial enlarged drawing among Fig. 2;

1 is backform among the figure, the 2nd, and external mold, the 3rd, internal mold, the 4th, bed die, 4' are the bed dies of change location, the 41st, hermetically-sealed construction two, 42nd, hermetically-sealed construction one, 43rd, hermetically-sealed construction three, 5th, Connection Block, the 6th, base, the 7th, steel cylinder, the 8th, bellmouth steel loop.

The specific embodiment

The utility model comprises the internal mold 3 of tubular, the external mold 2 of tubular, the bed die 4 of annular and the backform 1 of annular shown in Fig. 1-4, also comprise the base 6 that is fixedly installed on said inside and

outside mould

3,2 bottoms; Said bed die 4 is arranged on inside and

outside mould

3,6 tops of the base between 2.This kind state such as Fig. 1 are that the utility model product can be produced the state that greatly enhances (height) degree PCCP pipe most, and at this moment, the bottom surface of bed die 4 is fitted on the end face of base 6 (can adopt connector to connect).

Between bed die 4 and base 6, be provided with the circular Connection Block 5 that is used to regulate the bed die height, said Connection Block 5 end faces and said bed die 4 bottom surfaces removably connect, and the end face of the bottom surface of said Connection Block 5 and said base 6 removably connects.This kind state is like Fig. 2, shown in 3, and the bed die 4' of change location has been changed height by Connection Block 5, can produce the product of another specification.

No matter be Fig. 1 state or Fig. 2 state, between the bed die of adjustable height and inside and outside mould mating surface, leak, between the outer surface of the interior annular face of said bed die 4 and said internal mold 3, be provided with hermetically-sealed construction 1 for preventing concrete; Be provided with hermetically-sealed construction 2 41 between the exterior annular face of said bed die 4 and the inner surface of said external mold 2.Can prevent effectively that concrete from leaking.In addition, during processing PCCP pipe, steel cylinder 7 and bellmouth steel loop 8 need be set also,, can also set up hermetically-sealed construction 3 43 for preventing the leakage between bed die 4 and the bellmouth steel loop 8.

With production 5m, two kinds of specification PCCP pipes of 6m is example, and the punching block of other producer generally is made up of bed die, backform, external mold, internal mold.And the dual-purpose vibration punching block of the utility model also has Connection Block, base member divided by upper-part.The location of external mold, internal mold and steel cylinder is to lean on bed die and top cover accurately to locate.Connection Block is usefulness just when producing the 5m body only, and the lower end of Connection Block is connected with base with bolt, and the upper end is connected with bed die with bolt.External mold touch an opening structure that adopts single box body, a jackscrew structure is adopted in touching of internal mold.On interior external mold, should increase pneumatic vibrator, to guarantee the fineness of concrete packing and pipe of concrete inner surface after the tamping.

The utility model one mold can be produced the PCCP body of differing heights, greatly reduces user's production input cost.Also have punching block from heavy and light, vibrating effect is good, product surface is smooth, good airproof performance is difficult for spillage.Hold, socket working face size and die thickness size, can adjust according to actual needs.One mold can produce two kinds (5 ~ 6m) two kinds of differing heights and hold, socket working face size and the measure-alike body of die thickness.
