Summary of the invention
The present invention provides a kind of non-leakage concrete wall treatment of construction joints method and structure for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of concrete wall treatment of construction joints method; This concrete wall comprises some joint concrete wall joints of first after-pouring; Adjacent two joint concrete walls joints comprise the concrete wall joint of formerly building and at the concrete wall joint of after-pouring; Pre-buried steel plate for sealing water in the concrete wall joint of formerly building said, said steel plate for sealing water are positioned at the centre position at the constuction joint place of said adjacent two joint concrete walls joints; Install the cast gate that facade is bracket shape on said concrete wall joint top at after-pouring, said cast gate is higher than the constuction joint that said two adjacent joint concrete walls save; Build concrete from said cast gate, form said at after-pouring concrete wall joint and in cast gate, to form facade be the concrete body of bracket shape, said concrete body protrusion and covers the constuction joint between them outside said two adjacent joint concrete walls joints; The part of said steel plate for sealing water is embedded in the said concrete wall joint of formerly building, and another part is cast in said in the concrete wall joint of after-pouring.
This method is further comprising the steps of: treat after the concrete strength of the concrete wall of after-pouring joint reaches designing requirement, be that the concrete body of bracket shape cuts with the facade that forms in the cast gate, and use cement sand plaster.
Another technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of concrete wall constuction joint structure; This concrete wall comprises some joint concrete wall joints of first after-pouring; Adjacent two joint concrete walls joints comprise the concrete wall joint of formerly building and at the concrete wall joint of after-pouring; This constuction joint structure is included in pre-buried steel plate for sealing water in the said concrete wall joint of formerly building, and said steel plate for sealing water is positioned at the centre position at the constuction joint place of said adjacent two joint concrete walls joints; The part of said steel plate for sealing water is embedded in the said concrete wall joint of formerly building, and another part is cast in said in the concrete wall joint of after-pouring.
The concrete body that any side of the constuction joint that said two adjacent joint concrete walls save is coated with bracket shape.
Advantage and good effect that the present invention has are: in constuction joint, adopt steel plate for sealing water and adopt bracket shape cast gate to be cast in the concrete wall joint of after-pouring, the density of constuction joint and sealing property are good, and be non-leakage.And easy construction of the present invention, cost is low.
Description of drawings
Fig. 1 is for using the sketch map of a kind of concrete wall of the present invention treatment of construction joints method.
Among the figure: the concrete wall of 1, formerly building joint, 2, steel plate for sealing water, 3, at the concrete wall joint of after-pouring, 4, cast gate.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of concrete wall constuction joint structure; This concrete wall comprises some joint concrete wall joints of first after-pouring; Adjacent two joint concrete walls joints comprise the concrete wall joint 1 of formerly building and at the concrete wall joint 3 of after-pouring, this constuction joint structure is included in pre-buried steel plate for sealing water 2 in the concrete wall joint 1 of formerly building, and steel plate for sealing water 2 is positioned at the centre position at the constuction joint place of two adjacent joint concrete walls joints; The part of steel plate for sealing water 2 is embedded in the concrete wall joint 1 of formerly building, and another part is cast in the concrete wall joint 3 of after-pouring.
In order further to improve anti-permeability performance, the concrete body that any side of the constuction joint of two adjacent joint concrete wall joints is coated with bracket shape.
Above-mentioned concrete wall treatment of construction joints method, first pre-buried steel plate for sealing water 2 in the concrete wall joint 1 of formerly building makes steel plate for sealing water 2 be positioned at the centre position at the constuction joint place of above-mentioned adjacent two joint concrete walls joints; Save 3 tops at the concrete wall at after-pouring and install the cast gate 4 that facade is bracket shape, cast gate 4 is higher than the constuction joint that above-mentioned two adjacent joint concrete walls save; Build concrete from cast gate 4, being formed on the concrete wall joint 3 of after-pouring and in cast gate, forming facade is the concrete body of bracket shape, and the concrete body protrudes outside above-mentioned two adjacent joint concrete walls joints, and covers the constuction joint between them; The part of steel plate for sealing water 3 is embedded in the concrete wall joint 1 of formerly building, and another part is cast in the concrete wall joint 3 of after-pouring.
In the present embodiment, the concrete wall is a barrel, and cast gate 4 is an annular; Width is 200mm, is higher than constuction joint 300mm, is used to be cast in the concrete wall joint that the back forms; Make the concrete of building be easy to be filled into after the steel plate for sealing water 2 and be convenient to vibrate, thereby make concrete closely knit, guarantee the quality of constuction joint.After treating that concrete strength reaches designing requirement, the facade that will in cast gate, form is that the concrete body of bracket shape cuts, and with 1: 2 cement sand plaster.
If the concrete body that the above-mentioned facade that in cast gate, forms is a bracket shape does not influence the structure and the function of use of cyclone well, can it not cut, can save a large amount of people, material resources, speed up the work, can be used as the impervious reserve safeguard measure of constuction joint again.
Although combine accompanying drawing that the preferred embodiments of the present invention are described above; But the present invention is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
