Technical field
The utility model belongs to waterproof construction technical field, and more particularly to a kind of gunite concrete side wall joins with base plate to be stitched
Water sealing structure.
Background technology
With the development in epoch, the continuous progress of technique is domestic that wet spraying concrete technology is applied into entity first
Structure.The side wall that particularly polymorphic structure cast-in-place concrete base plate is constructed with wet shot method is often constructed in two times, forms one
Road vertical construction joints.
Traditional handicraft typically carries out the water-proofing treatment at construction joint using steel plate for sealing water, construction joint is retained in into base plate upward
On 300mm side wall, it is easy to the installation of steel plate for sealing water.Due to carrying out the construction of structure side wall, steel plate for sealing water using spray technology
Setting have impact on jeting effect, cause steel plate for sealing water posterior components not spray closely knit.Especially for polymorphic structure, due to shape
Shape is with Curvature varying, and steel plate for sealing water is difficult to follow the curvature of change to be laid, and using traditional handicraft primary concreting bottom
Plate and the high side walls of 300mm, not only hoisting die construction 300mm assault walls difficulty is larger while it is difficult to ensure that the quality of parapet；Using
Gunite concrete carries out the construction of top side wall, and two kinds of technique finished surface perception effects have notable difference.So conventionally employed stop
The method of water steel plate can not meet polymorphic structure base plate and the waterproof requirement of side wall is located at and base plate, it is necessary to which vertical construction joints are stayed
The concordant position in upper surface.
Utility model content
The purpose of this utility model is to provide the water sealing structure of a kind of side wall and base plate handing-over seam, and its is simple and reliable for structure,
The construction characteristic for the side wall that cast-in-place concrete base plate is constructed with wet shot method can be met simultaneously.
To achieve the above object, the utility model takes following technical scheme：
A kind of water sealing structure of side wall and base plate handing-over seam, it includes the base plate and gunite concrete that cast in place process is produced
The side wall of technique productions, the side wall is located on the plate top surface, forms the seam being located on the plate top surface；Plate top surface position
The sealing adhesive tape that water-swellable is provided with the groove parallel with the seam, the groove is provided with the part in the seam；The side wall
The one end of bottom surface on the outside of the seam is provided inwardly with the recess parallel with the seam, and the recess is stepped, is coated with sealing
Glue.
Further, the groove inner wall is coated with gelatinous layer.
Further, the groove is two, and is parallel to each other.
Further, the distance between the groove and the seam edge are more than 75mm.
The beneficial effects of the utility model are：Water-swellable sealing adhesive tape of the present utility model is flexible material with fluid sealant
Material, can meet the process characteristic of gunite concrete, while can also meet the complex-shaped changeable shape of cast-in-place base plate polymorphic structure
Shape feature, is suitably applied gunite concrete structure side wall and cast-in-place back plate connections waterproofing node.
Brief description of the drawings
Fig. 1 is the structural representation of the water sealing structure of the utility model side wall and base plate handing-over seam.
Fig. 2 is the enlarged diagram of the seam crossing of the utility model side wall and base plate handing-over seam.
Embodiment
In order that the technical solution of the utility model and beneficial effect are more clearly understood, with reference to embodiments with it is attached
Figure, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As shown in Figure 1 and Figure 2, the utility model provides the water sealing structure of a kind of side wall and base plate handing-over seam, and it includes cast-in-place
The side wall 2 of base plate 1 and the shotcrete technology production of technique productions, the side wall 2 is located on the top surface of base plate 1, forms position
Seam 3 on the top surface of base plate 1.The part that the top surface of base plate 1 is located in the seam 3 is provided with the groove parallel with the seam 3
4, such as two and it is parallel to each other.Sealing adhesive tape 5 is provided with the groove 4, the sealing adhesive tape 5 being capable of water-swellable.The bottom of side wall 2
Face is provided inwardly with the recess 6 parallel with the seam 3 close to the one end in the outside of seam 3, and the recess 6 is stepped, is coated with close
Sealing 7.
It is preferred that, the inwall of groove 4 is coated with gelatinous layer, to increase attachment of the sealing adhesive tape 5 in concrete groove 4
Power.
Base plate is arranged on the position concordant with the upper surface of base plate by the utility model with the construction joint of side wall, using meeting water
The dilating principle of expansion water-stop adhesive tape, by setting twice sealing adhesive tape fluid sealant (one-component polyurethane sealant) with together with
Form carries out the water-proofing treatment at cold seam.Specifically, the utility model is in installation, according to the following steps：
1. it is pre- at side wall 2 with the seam 3 of base plate 1 using twice formed rubber strip first in casting concrete base plate 1
Twice groove 4 (notch size 20mmx25mm) is stayed, the distance between the groove 4 and the edge of seam 3 are more than 75mm, for pacifying
Fill water-swellable sealing adhesive tape 5.
2. water-swellable sealing adhesive tape 5 is using tool hydrophily, hydrophilic polymer type, and salt water resistance and resistance to microorganism, rule
Lattice use 20mmx25mm.Sealing adhesive tape 5, which should have to be delayed to, meets water starts expansion characteristic after continuous ten days, to prevent applying
Work condition produces advance expansion, and prevents that the expansion that concrete is obtained before complete intensity by sealing adhesive tape 5 from extruding.By groove 4
Clean out, progress side template installs the colligation with first of the reinforcing bar of side wall 2.
3. clearing up groove 4 again, any dust and debris are carefully wiped, then in dry concrete surface (water-stop glue
The place that bar 5 is placed) smear one layer of priming paint or colloidal materials.Priming paint or colloidal materials provide one without dust, gluing
Surface improves adhesive force of the water-swellable sealing adhesive tape 5 inside concrete.
4. when priming paint or colloidal materials exsiccation is touched, carry out the installation of water-swellable sealing adhesive tape 5.It is light with hand
Light side pressure, makes water-swellable sealing adhesive tape 5 be fixed on a position, forms a series of pearl, checks again for and confirm to stop
Glue bar 5 is in correct position.
5. completing the remaining reinforcing bar binding work of side wall 2, the preparation before side wall 2 sprays is carried out.
6. before the construction of shotcrete of side wall 2, in one end formed rubber strip of the bottom surface of side wall 2 on the outside of seam 3
Recess 6 is reserved, to be coated with fluid sealant 7, the size 13mmx13mm of recess 6.
7. after after the concrete hardening of side wall 2, formed rubber strip is taken out, hairbrush or other suitable one layer of instrument brushings are used
The thin primary coat of epoxy radicals, it is to be dried after in the material of recess filling with sealant 7.
After 8. the construction of fluid sealant 7 is finished, fluid sealant is struck off into compacting with pressure tongue rod, scraping blade, strengthens sealing effectiveness.
The above, is only preferred embodiment of the present utility model, not makees any to structure of the present utility model
Formal limitation.It is every any simple modification made according to technical spirit of the present utility model to above example, equivalent
Change and modification, in the range of still falling within the technical solution of the utility model.
