Abstract

The utility model discloses an anti-bank structure with a water stop steel plate, wherein the water stop steel plate is pre-embedded at the position of a floor slab corresponding to an anti-bank, the water stop steel plate is a closed rectangle, and the cross section of the water stop steel plate is in an L shape; the vertical end of the water stop steel plate is exposed out of the floor slab by 35-40 mm; the vertical end of the water stop steel plate is located at the lower central position of the inverted ridge section. The utility model has the advantages that: because the water stop steel plate is arranged in advance and is higher than the floor slab by a certain distance, the leakage of the joint of the reversed ridge and the floor slab is avoided, the bonding strength of the reversed ridge and the floor slab is enhanced, and the sealing effect is better.

Description

Anti-bank structure with stagnant water steel sheet
Technical Field
The utility model relates to a building field, a reverse bank structure specifically says so.
Background
In traditional house concrete structure work progress, the anti-bank of 200 high concretes in bathroom generally needs the secondary to pour into a mould, should the old concrete face carry out the chisel hair and handle before the secondary concretes, nevertheless because there are some chisel hairs insufficient in the workman work progress, phenomenon such as concrete vibration is not closely knit has left the seepage hidden danger for concrete construction joint department.
Disclosure of Invention
In order to reduce the seepage risk of the anti-bank construction joint department of concrete, the utility model aims at providing an anti-bank structure of bathroom is through reserving stagnant water steel sheet, using the machinery chisel hair, ensures that the anti-bank construction joint of concrete does not leak. The specific technical scheme is as follows:
a water stop steel plate is embedded in a position, corresponding to a reverse ridge, of a floor slab in advance, the water stop steel plate is a closed rectangle, and the cross section of the water stop steel plate is L-shaped; the vertical end of the water stop steel plate is exposed out of the floor slab by 35-40 mm; the vertical end of the water stop steel plate is positioned at the lower central position of the inverted ridge section; the horizontal end of the water stop steel plate is positioned in the closed area of the reverse ridge.
One side of the water stop steel plate is arranged below the shear wall.
One edge of the water stop steel plate is connected with the shear wall into a whole through a water swelling water stop strip.
The water-swelling water stop strip is fixed between the water stop steel plate and the shear wall by cement steel nails or catching groove glue.
The utility model has the advantages that: because the water stop steel plate is arranged in advance and is higher than the floor slab by a certain distance, the leakage of the joint of the reversed ridge and the floor slab is avoided, the bonding strength of the reversed ridge and the floor slab is enhanced, and the sealing effect is better.

Detailed Description
The present invention is specifically described below with reference to the accompanying drawings, as shown in the drawings, a water stop steel plate 4 is pre-embedded in a position of the floor slab 1 corresponding to the inverted ridge 3, the water stop steel plate 4 is a closed rectangle, and the cross section of the water stop steel plate is L-shaped; the height of the vertical end of the water stop steel plate exposed out of the floor slab is 35-40 mm; the vertical end of the water stop steel plate is positioned at the lower central position of the section of the reversed ridge 3; the horizontal end of the water stop steel plate is positioned in a closed area of the reversed ridge, and the closed area is an area of a toilet.
When the shear wall is poured, one edge of the water stop steel plate is arranged below the shear wall.
If the shear wall 2 is poured, one edge of the water stop steel plate is connected with the shear wall into a whole through a water swelling water stop strip 5. The water-swelling water stop strip 5 is fixed between the water stop steel plate and the shear wall by cement steel nails or catching groove glue.
The utility model discloses a construction method as follows:
(1) processing of water-stop steel plate
Selecting the type of angle steel: and L50 and 50 are used as raw materials of the water stop steel plate, angle steel is processed in advance according to the size of a back sill of the toilet, and a closed rectangular box is formed.
The water stop steel plate is processed into a closed rectangular form for standby, four angle-divided horizontal welding seams and four angle-divided vertical welding seams are respectively subjected to full welding, the quality of the welding seams is noticed, and water cannot be leaked.
(2) Placing and fixing of miniature water stop plate
The position of placing of stagnant water steel sheet is confirmed according to the position of anti-bank, ensures that the vertical limit of stagnant water steel sheet is in the position placed in the middle of anti-bank cross-section, and stagnant water steel sheet position is fixed well back, carries out welded fastening to stagnant water steel sheet and concrete structure board gluten according to a meter interval.
If the shear wall is poured, the reverse ridge is provided with a vertical construction joint which is in contact with the shear wall surface, and the construction joint stops water in a mode of fixing the water-swelling water stop strip.
The scheme selects a PZ product type water swelling water stop strip with the cross section size of 10 multiplied by 25mm, and the water stop strip is fixed at a construction joint by cement steel nails or a catching groove in an adhesive manner.
(3) Roughening treatment:
although the water stopping measures are provided at the concrete construction joint, before the concrete reversed ridge is poured, the scabbling is still required to be carried out according to the standard requirement, and the scabbling quality is required to meet the requirement. And after the chiseling is finished, cleaning floating ash on the surface of the concrete, and watering and wetting the old concrete surface before pouring the concrete.
(4) Supporting and reinforcing method for inverted ridge template
The reverse sill pouring quality of one project can very reflect the management level of the whole project, the erecting quality of the reverse sill template directly influences the concrete forming quality, the reverse sill template needs to select a high-quality template, and the erecting must be firm and the size is accurate. One wood purlin must be placed up and down on the outer side of the template to serve as a back ridge, and the inner side of the template can be subjected to size positioning through steel nails or pre-buried positioning steel bars. The sizing clamps are arranged one meter apart.
(5) Concrete pouring and vibrating
(1) Concrete transportation
① the concrete mixer truck is to be transported to the pouring site by a tip lorry, a hand truck or a bucket in time after being unloaded.
When transporting concrete, the loss of cement paste should be prevented.
② the time from discharging the concrete with the mixer to pouring is not more than 90min when the air temperature is higher than 25 deg.C.
(2) Pouring and vibrating concrete
① cutting the root of the concrete, brushing plain cement paste or dry-scattering JS concrete waterproof agent before pouring, ② pouring method, namely shoveling the concrete into a mould by a spade, ③ concrete vibrating, wherein when vibrating and cutting the concrete, the vibrating rod forms an oblique angle with the concrete surface and vibrates obliquely, ④ surface smoothing, namely, when the concrete is cut to a section after vibrating, a wooden trowel is used for compacting and smoothing immediately, no loose concrete is needed on the surface, 3, when the concrete is cured and poured by the concrete curing agent for 12h, the concrete is covered and watered for curing, at least twice a day at normal temperature, and the curing time is not less than 7 d.
