Abstract

The utility model relates to a preformed hole die for a high building pipeline, which is composed of a hard cone tube. The top and the bottom surfaces of the tube body are respectively provided with reinforcing ribs, the reinforcing ribs on the central axis of the cone are respectively provided with through holes, and a center hole of the reinforcing rib on the small end of the cone tube is provided with a fishtail bolt. The utility model has the advantages of simple structure, easy fabrication and convenient operation. The utility model can effectively enhance the leakage prevention level of a preformed hole for water supply pipes and drainage pipes of a building, reduce the labor strength of labors, and improve the installation accuracy of the water supply pipes and the drainage pipes. The utility model is suitable for being used as a preformed hole die of the water supply pipes and the drainage pipes of construction.

Description

A kind of highrise building pipeline preformed hole mould

The utility model relates to a kind of building operations mould, and refering in particular to is a kind of highrise building pipeline preformed hole mould.

When water supply and sewerage pipeline is reserved buried via hole in the building operations, often adopt round log or common brick preformed hole, and then mend perforate or chiso-mallet reaming according to the size of supplying drainage, this job practices is complex process not only, labor strength is big, when the more important thing is the chiso-mallet reaming, easily cause concrete pouring plate break muscle, cracking, influence floor structure intensity, and " eight " font hole that forms during the chiso-mallet reaming, when pipe laying, it is closely knit that the fine sand concrete cast is difficult for concrete, cause the floor seepage, not only time-consuming expense material but also influence the total quality of building.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and processing and manufacturing is easy, and is easy to use, can effectively improve the highrise building pipeline preformed hole mould of building supplying drainage installation quality.

The utility model is to adopt following proposal to realize: it is made of a hard circular cone tube, respectively be provided with a reinforcing rib in the upper and lower bottom surface of cylindrical shell, on the circular cone central axis on the reinforcing rib, respectively be provided with a through hole, and in the centre bore of awl tube small end reinforcing rib, a fishtail bolt be installed.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model master sectional view;

Accompanying drawing 2 is the vertical view of accompanying drawing 1.

See accompanying

drawing

1,2, the utility model is made of cylindrical shell 1, upper surface reinforcing rib 2, lower surface reinforcing rib 3, described cylindrical shell 1 is conical, upper and lower bottom surface respectively is provided with a reinforcing rib 2,3, on the central axis that is in cylindrical shell 1 on the reinforcing rib 2,3, respectively be provided with a through

hole

4,5, and in through hole 5, be provided with a CONTEN STEEL OVAL NECK TRACK BOLTS 6.

Using method of the present utility model is summarized as follows: in the building operations, the axis coordinate that provides by the architectural design drawing, find out water supply and sewerage pipeline preformed hole coordinate points in conjunction with mounting template, behind flooring arrangement of reinforcement dress mould, on template, bore an aperture, CONTEN STEEL OVAL NECK TRACK BOLTS in the utility model 6 is passed aperture and fix with nut, can be to the flooring fluid concrete, get final product the demoulding after three hours, after the last layer template installs, with the through hole on the reinforcing rib on the utility model 24 is centre bore, find out upper floor with the mode of messenger wire and keep for the gutter central point, same, on upper former, bore a through hole, CONTEN STEEL OVAL NECK TRACK BOLTS 6 is passed the template through hole and the utility model is installed on the upper former, can upper former be poured into a mould; Method according to this, can guarantee that highrise building supplying drainage preformed hole is concentric, and preformed hole is a conical bore, improved the installation accuracy of water supply and sewerage pipeline, and when taper hole was filled at follow-up concrete, it was closely knit to be easy to concrete, can effectively improve flooring antiseep level, and can effectively reduce labor strength, be beneficial to the execution standardization construction.

In sum, the utility model is simple in structure, and processing and manufacturing is easy, easy to use, can improve effectively that building is given, gutter preformed hole antiseep level, reduce labor strength, improve the supplying drainage installation accuracy, be suitable for using as supplying drainage preformed hole mould in the building operations.

Claims

A kind of highrise building pipeline preformed hole mould, constitute by cylindrical shell 1, upper surface reinforcing rib 2, lower surface reinforcing rib 3, it is characterized in that: cylindrical shell 1 is for conical, upper and lower bottom surface respectively is provided with a reinforcing rib 2,3, on the central axis that is in cylindrical shell 1 on the reinforcing rib 2,3, respectively be provided with a through hole 4,5, and in through hole 5, be provided with a CONTEN STEEL OVAL NECK TRACK BOLTS 6.
