Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction method for a horizontal construction joint water stop steel plate at a buttress not to penetrate through a stirrup.
Background
The waterproof quality of basement structural engineering is always regarded as the important content of quality control in the building engineering industry, wherein the waterproof quality of basement exterior wall structures is the main content of management of each construction project. According to the construction requirements of the basement exterior wall, a horizontal construction joint needs to be arranged on the wall body, and how to make the construction of the horizontal construction joint is guaranteed, so that the later underground construction backfill is completed, the pressure water seepage condition does not occur at the exterior wall construction joint, and the important point of project quality management is to be achieved. In the construction of establishing staying of horizontal construction joint, the pre-buried installation of outer wall "buttress post" department stagnant water steel sheet appears the quality problems very easily, buries the seed of hidden danger for later stage infiltration.
In the traditional construction method, when the water stop steel plate is embedded in the horizontal construction joint of the buttress column, the water stop steel plate needs to completely disconnect the stirrups in the encryption area of the buttress column, and then the stirrups are welded with the water stop steel plate; or drilling a hole in the water stop steel plate, and then welding the stirrup and sealing the hole after penetrating through the column stirrup. These two approaches have problems: the stirrups in the 'buttress' encryption area need to be completely disconnected, and the stirrups are welded after the water stop steel plate is installed. The quality of the welded stirrup cannot be guaranteed. Certain hidden trouble is caused to the structure safety. 2. Because of general stagnant water steel sheet thickness is about 3mm, no matter be with stirrup and stagnant water steel sheet weld, still drill on the stagnant water steel sheet, carry out the welding of rewelding and hole behind the installation stirrup and seal, all exert an influence to the stagnant water effect of stagnant water steel sheet, can't guarantee stagnant water steel sheet quality, there is serious seepage risk in the later stage.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in FIG. 1, the invention relates to a construction method for a horizontal construction joint water-stop steel plate at a buttress, which does not penetrate through a stirrup, the outer side of the buttress column 3 connected with the basement outer wall 1 is provided with a conversion channel constructional column ear 4 for installing the water-stopping steel plate 2 of the horizontal construction joint, during the pre-buried installation construction of the water-stopping steel plate 2, the water stop steel plate 2 beside the buttress column 3 is directly arranged between the column lugs 4 in a bypassing way, and is converted back to the horizontal construction joint of the original outer wall 1 after passing through the buttress column 3, the method takes the column ear 4 as a conversion path for installing the water stop steel plate at the buttress column 3, avoids the problem that the hooping of the column encryption area needs to be integrally disconnected when the water stop steel plate is installed at the buttress column 3, and the water stop steel plate 2 is welded again after being installed, or the water stop steel plate 2 is drilled in advance to form a hole for penetrating the stirrup, and after the later-stage stirrup is installed, the hole is welded and sealed by the traditional construction method.
As shown in fig. 1 and 2, the size of the water-stop steel plate 2 is 300X3mm, and the conversion channel post lug 4 for installing the water-stop steel plate 2 has a thickness of 200mm and an overall height of 400mm, so as to ensure the thickness of the protective layer of the water-stop steel plate 2 outside the buttress post 3. The length of the column lug 4 is 100mm (namely the length of the column lug 4 is B +200 mm) of each side of the structural size B of the buttress column 3, and the column lug is used for enabling the water stop steel plate 2 to be wound and bent at the joint of the buttress column 3 and the outer wall to enter the column lug 4. When the horizontal construction joint is reserved, a formwork is erected to set a half of the column lug 4, when the wall body above the horizontal construction joint is poured for the second time, the formwork of the remaining half of the column lug 4 is erected, and finally the construction of the horizontal construction joint outside the buttress column-3 is completed.
As shown in fig. 3, the water stop steel plate 2 is installed in the middle of the column lug 4 to ensure the thickness of the protective layer of the water stop steel plate 2, and after the construction of the lower part of the horizontal construction joint of the basement exterior wall is completed and before the concrete on the upper layer of the horizontal construction joint is poured, the concrete on the column lug 4 needs to be chiseled and coated with plain cement paste for one time. The new and old concrete of being convenient for can effectively carve to close the bonding, reduces later stage infiltration risk.
In the design of the invention, by arranging the structure of the column lugs 4, the situation that the stirrups in the encryption region of the buttress column 3 need to be cut off, the water-stopping steel plate needs to be installed and the stirrups need to be welded again in the installation process of the water-stopping steel plate 2 of the horizontal construction joint at the traditional buttress column 3 is avoided; or the construction procedures of drilling the water-stopping steel plate, installing the water-stopping steel plate 2, installing the column stirrups, welding and sealing holes and the like are carried out according to the distance between the stirrups in advance. By adopting the construction method of the invention, the installation of the water stop steel plate 2 and the binding construction of the column stirrup are synchronously carried out, and the construction efficiency is accelerated. Eliminate the later stage because of the structural quality hidden danger that stirrup welding arouses, greatly reduce to 2 drilling opening holes of stagnant water steel sheet arouse that the stagnant water effect is not good to lead to the emergence condition of structure later stage infiltration hidden danger. And reduce the later stage because of the produced construction cost consumption of the water quality problem reprocessing treatment of infiltration, reduce the construction cost and practice thrift the project cost.
The invention has the design application range that: the underground structure contains all reinforced concrete projects clinging to the backfill buttress columns. The above are only specific application examples of the present invention, and other embodiments of the present invention may be adopted, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
