Abstract

The present invention relates to a method for jointing seam between upper and lower concrete layers-of concrete wall body. Said method includes the following steps: a), Except for most upper layer concrete of said wall body making one side of upper end of every layer concrete into the form of inwards-recessed rectangular notch whose depth is L cm and height is H cm; b), along the outside edge of said above-mentioned notch sticking single-side-adhesive spongs strip whose width is B cm; c), mounting relative upper layer concrete form, pouring concrete and forming relative upper concrete layer; and d), removing form and cleaning out the above-mentioned stuck single-side-adhesive sponge strip.

Description

A kind of method of jointing concrete between upper and lower layers of wall body in concrete

Technical field

The present invention relates to a kind of method of building operations, in particular, relate to a kind of method of jointing concrete between upper and lower layers of wall body in concrete.

Background technology

The construction of concrete wall generally all is to adopt upwards successively to build template, laminated pouring, and desired height finishes until reaching.Obviously see each seam of concrete layer intersection up and down building good concrete wall physical efficiency like this, may also have the evagination phenomenon at the upside of this seam crossing.This is because the upper former lower end due to cast the time is subjected to the lateral pressure F of template inner concrete slurries, is commonly called as " mould expands ", sees also Fig. 3.In addition, template inner concrete slurries can spill from the gap between upper former and the following concrete aspect, are commonly called as " spillage ", form sagging G at following concrete laminar surface.For this reason, behind the concrete wall casting complete, also need body of wall is polished, to keep the smooth bright and clean of surface of wall.This has increased the cost of labor of wall construction undoubtedly, also can cause the waste of material simultaneously owing to spillage, the mould that expands.In addition, when concrete wall is polished, the time regular meeting be ground to reinforcing bar in the body of wall, thereby influence the intensity of body of wall.

Summary of the invention

Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, design that a kind of concrete wall for laminated pouring can realize not having seam, no spillage, do not have the method for a kind of jointing concrete between upper and lower layers of wall body in concrete of the mould phenomenon that expands, it is realized by following technical scheme:

Comprise the following steps:

A. except that described body of wall the superiors concrete, each layer concrete upper end one side is made and is inwardly concaved the degree of depth and be L centimetre, highly be H centimetre rectangular indentation;

B. pasting width along the outer side edges of above-mentioned breach is the single face gelatin sponge bar of B;

C., relative upper strata concrete form is installed, and fluid concrete forms relative upper concrete layer;

D. stripping is removed the single face gelatin sponge bar of being pasted.

Described notch depth L=1.0～1.5 centimetres, height H=20～30 centimetre.

Width B=2～3 of described single face gelatin sponge bar centimetre.

The invention has the beneficial effects as follows: 1) rectangular indentation is set in the upper end of each concrete layer, and with the located lateral standard of this breach as the upper concrete layer template, make concrete layer located lateral accurate, thereby guarantee the required precision of the coplane degree of body of wall, can effectively remove the bloated mould phenomenon that form lateral pressure is caused by concrete slurry simultaneously; 2) body of wall does not need polishing, thus, improves on the one hand work efficiency, reduces cost of labor, reduces spillage of material, material-saving material cost owing to no spillage and bloated mould phenomenon on the one hand.

The specific embodiment

Embodiment 1

Present embodiment is building one a plane concrete wall.The laminated pouring of this concrete wall will be undertaken by following step:

A. except that body of wall is gone up a concrete layer most, each concrete layer upper end is made its outside one side by the template of building and is inwardly concaved degree of depth L=1.0 centimetre, and the rectangular indentation of height H=20 centimetre sees also Fig. 1.

B. pasting width along the outer side edges of above-mentioned breach is centimetre single face gelatin sponge bar of B=2.

C., the upper concrete layer template of above-mentioned relatively concrete layer is installed, and after installing, fluid concrete forms upper concrete layer.

D. remove the upper concrete layer template, remove the single face gelatin sponge bar of all stickups.

After pressing the above-mentioned steps repeated several times, the body of wall cast reaches maximum layer concrete layer, and when building the template of this concrete layer, its upper end does not need to have designed above-mentioned rectangular indentation again, sees also Fig. 2.

Embodiment 2

Present embodiment is building one a circular concrete wall.The laminated pouring of this concrete wall will be undertaken by following step:

A. except that body of wall is gone up a concrete layer most, each concrete layer upper end is made its outside one side by the template of building and is inwardly concaved degree of depth L=1.5 centimetre, the rectangular indentation of height H=30 centimetre, referring again to Fig. 1, this rectangular indentation essence is the arc surface breach of a rectangle profile.

B. pasting width along the outer side edges of above-mentioned breach is centimetre single face gelatin sponge bar of B=2;

C., the upper concrete layer template of above-mentioned relatively concrete layer is installed, and after installing, fluid concrete forms upper concrete layer;

After pressing the above-mentioned steps repeated several times, the body of wall cast reaches maximum layer concrete layer, and when building the template of this concrete layer, its upper end does not need to have designed above-mentioned rectangular indentation again, please again referring to Fig. 2.

When using the inventive method to come the laminated pouring concrete wall owing to be provided with breach in each concrete layer upper end, when building relative upper concrete layer template, can this breach as the located lateral standard, can make the upper concrete layer located lateral more accurate like this.Simultaneously,, the lateral pressure of the suffered concrete slurry in upper concrete layer lower end is alleviated greatly, thereby eliminated seam crossing that bloated mould causes and show especially and resemble because has born by concrete slurry the formed lateral pressure in upper concrete layer one side template lower end this breach side.The method that single face gelatin sponge bar is pasted in the breach outside, following concrete layer upper end of being adopted in the inventive method can effectively prevent spillage, the sagging vestige can not occur.Therefore, smooth bright and clean with the metope after the inventive method cast, no seam, no sag, no evagination phenomenon need not the polishing of polishing, thereby except that the work efficiency height, save cost, spillage of material little, can not cause also that reinforcing bar is worn and torn by accident in the body of wall, strength of wall body is affected.
