Abstract

The invention relates to a method for constructing the mould of rectangle liquid storage structure, which is purposed to replace steel mould with little wood fern, to overcome the defects of former branch mould. It comprises following steps that: (1) combining the steel moulds (2) into combined steel mould, while there is space at the middle to mount wood fern (6); (2), setting one through hole that mounting drawing check bolt (5) with dual head nut at each 1 meter on the wood fern (6); (3) the iron wire (7) is through the pin hole of steel mould (2) and the through hole of wood fern (6) that relative to the pin hole, to connect the steel mould (2) and the wood fern (6); (4), using transverse rod (4) to connect the wall plate (1) and the combined mould distantly along the outward horizontal direction; (5), on the outward vertical direction of wall plate (1), using three-shape clamper (8) to mount upright rod (3) at two sides of wood fern (6); (6), using said drawing check bolt (5) to connect the moulds of inner and outer walls.

Description

The job practices of template in the rectangle liquid storage structure

Technical field

The present invention relates to the template construction technology of wallboard in the rectangle liquid storage structure.

Background technology

At present, the template construction of wallboard in the cast-in-place monolithic reinforced-concrete rectangle liquid storage structure, main method is to adopt the formwork of support to be arranged and do not have two kinds of methods of the formwork of support, though these methods have been brought into play positive effect to the cast of finishing liquid storage structure.Its weak point is: in the construction of large-scale rectangular liquid storage structure, have the template that supports formwork method to walk about easily.Do not have the drawknot sealing bolt that supports formwork method and must penetrate template, damaged template is more like this, causes the formwork expense than higher.

Summary of the invention

The objective of the invention is to overcome the deficiency of mold method in the past by replacing steel form with a spot of wooden spinulose tree fern.

The present invention is the job practices of template in the rectangle liquid storage structure, the steps include:

(1) steel form (2) is combined into width less than 1 meter combined steel formwork, the gap that wooden spinulose tree fern (6) is installed is reserved in the centre;

(2) go up every 1 meter through hole of offering a mounting strap double end nut sealing bolt (5) wooden spinulose tree fern (6);

(3) iron wire (7) passes the last pin hole of steel form (2) and goes up the through hole that relative steel form (2) is gone up the pin hole position with wooden spinulose tree fern (6), and steel form (2) and wooden spinulose tree fern (6) are coupled together;

(4) on the horizontal direction inside and outside the wallboard (1), be connected with gang form at a certain distance with cross bar (4);

(5) on the vertical direction inside and outside the wallboard (1), lay vertical rod (3) with 3 shape fasteners (8) in the both sides of wooden spinulose tree fern (6);

(6) the drawknot sealing bolt (5) with band double end nut connects the inside and outside wall template.

The invention has the beneficial effects as follows:

The present invention structurally does cross bar and montant with scaffolding pole, has overcome the phenomenon that template is walked about.None damage of steel form, and wooden spinulose tree fern can be had enough to meet the need use, thus reduce construction cost greatly.After the form removal, wall is smooth, has the good technical effect.For condition has been created in the continuous pouring of liquid storage structure.

Drawknot sealing bolt (5) passes part and replaces with wooden spinulose tree fern (6), thereby has avoided the damaged template that causes because of perforation, has reduced the formwork expense.

Description of drawings

Fig. 1 a does not have the structural representation that supports formwork in the prior art, Fig. 1 b is that A-A is to sectional view among Fig. 1 a, and its Reference numeral and corresponding name are called: wallboard (1), steel form (2), montant (3), cross bar (4), drawknot sealing bolt (5).

Fig. 2 a is a structural representation of the present invention, and Fig. 2 b is that B-B is to sectional view among Fig. 2 b, and its Reference numeral and corresponding name are called: wallboard (1), steel form (2), montant (3), cross bar (4), drawknot sealing bolt (5), wooden spinulose tree fern (6), iron wire (7), 3 shape fasteners (8).

The specific embodiment

As shown in Figure 2, step of the present invention is:

1, P20 or P30 set shaped steel formwork (2) are combined into width less than 1 meter combined steel formwork, certain distance is reserved in the centre, so that wooden spinulose tree fern (6) is installed.

2, go up every 1 meter through hole that gets out φ 12, so that the drawknot sealing bolt (5) of mounting strap double end nut wooden spinulose tree fern (6).

3, iron wire (7) passes the last pin hole of steel form (2) and goes up the through hole that relative steel form (2) is gone up the pin hole position with wooden spinulose tree fern (6), and steel form (2) and wooden spinulose tree fern (6) are coupled together;

4, on the horizontal direction inside and outside the wallboard (1), be connected reliably with gang form at a certain distance with cross bar (4).

5, on the vertical direction inside and outside the wallboard (1), lay montant (3) with 3 shape fasteners (8) in the both sides of wooden spinulose tree fern (6).

6, the drawknot sealing bolt (5) with band double end nut reliably connects the inside and outside wall template.

Claims (1)

1, the job practices of template in the rectangle liquid storage structure is characterized in that

(1) steel form (2) is combined into width less than 1 meter combined steel formwork, the gap that wooden spinulose tree fern (6) is installed is reserved in the centre;

(2) go up every 1 meter through hole of offering the drawknot sealing bolt (5) of a mounting strap double end nut wooden spinulose tree fern (6);

(3) iron wire (7) passes the last pin hole of steel form (2) and goes up the through hole that relative steel form (2) is gone up the pin hole position with wooden spinulose tree fern (6), and steel form (2) and wooden spinulose tree fern (6) are coupled together;

(4) on the horizontal direction inside and outside the wallboard (1), be connected with gang form at a certain distance with cross bar (4);

(5) on the vertical direction inside and outside the wallboard (1), lay vertical rod (3) with 3 shape fasteners (8) in the both sides of wooden spinulose tree fern (6);

(6) the drawknot sealing bolt (5) with band double end nut connects the inside and outside wall template.
