Description
Technical Field
The utility model relates to a PC outer wall and seal structure of cast-in-place floor conversion layer belongs to the novel construction mode in building field.
Background
The assembly type building is a novel building construction mode, not only can the construction efficiency be improved, but also the assembly type building has the advantages of being larger than the traditional mode in the aspects of energy saving, noise reduction, environmental protection and the like, and is bound to become the mainstream of building development in the future. The PC building is a scientific and technological innovation demonstration project for residential industrialized building construction, is favorable for improving the quality, radically treating common diseases of leakage and cracks of an outer wall and accelerating the project progress. Meanwhile, the PC building has the following advantages: 1. the engineering progress can be accelerated; 2. the quality of building products is improved, and customers are won; 3. the construction site civilized construction and safety management are facilitated; 4. is beneficial to environmental protection and resource saving.
However, in the construction process, because the design drawing is not detailed, the sealing and plugging measures of the outer side of the grouting bin by using the traditional method cannot meet the requirements in the construction of the transfer floor, and the leakage phenomenon is frequent, so that the effect of the outer wall is influenced, and the production efficiency is also influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a sealing structure of PC outer wall and cast-in-place floor conversion layer, this sealing structure not only can prevent the thick liquid phenomenon of leaking, does not occupy the space in slip casting storehouse moreover.
For solving the above problems, the specific technical scheme of the utility model is as follows: a sealing structure of a PC outer wall and a cast-in-place floor conversion layer is characterized in that embedded steel bars are arranged on the upper end surface of the outer wall of the conversion layer, a prefabricated outer wall plate is built on the upper surface of the outer wall of the conversion layer, and the embedded steel bars are inserted into the bottom surface of the prefabricated outer wall plate; the outer surface of the outer wall of the conversion layer is provided with a channel steel support through bolts, the channel steel support is horizontally arranged, the upper surface of the channel steel support corresponds to the upper surface of the outer wall of the conversion layer, elastic rubber-plastic strips are pasted on the upper surface of the channel steel support, and the pasted elastic rubber-plastic strips are compressed by the lower surface of the prefabricated outer wall panel.
And pouring a conversion layer cast-in-place surface between the conversion layer outer wall and the prefabricated outer wall plate, and arranging an inclined support embedded nut in the conversion layer cast-in-place surface.
This sealing structure of PC outer wall and cast-in-place floor conversion layer adopts above-mentioned structure, utilizes the channel-section steel support to support elasticity rubber and plastic strip, and elasticity rubber and plastic strip has not only guaranteed sealed effect, does not occupy the space in slip casting storehouse moreover.
Drawings
Fig. 1 is a schematic diagram of a sealing structure of a PC outer wall and a cast-in-place floor conversion layer.
Detailed Description
As shown in fig. 1, in the sealing structure of the PC outer wall and the cast-in-place floor conversion layer, embedded steel bars 2 are arranged on the upper end surface of the conversion layer outer wall 1, a prefabricated outer wall plate 3 is built on the upper surface of the conversion layer outer wall 1, and the embedded steel bars 2 are inserted into the bottom surface of the prefabricated outer wall plate 3; the outer surface of the outer wall 1 of the conversion layer is provided with a channel steel support 4 through a bolt, the channel steel support 4 is horizontally arranged, the upper surface of the channel steel support 4 corresponds to the upper surface of the outer wall 1 of the conversion layer in position, an elastic rubber plastic strip 5 is pasted on the upper surface of the channel steel support 4, the pasted elastic rubber plastic strip 5 is compressed by the lower surface of the prefabricated outer wall panel 3, and the sealing performance of the prefabricated outer wall panel 3 and the outer wall 1 of the conversion layer is realized.
Pouring a conversion layer cast-in-place surface 6 between the conversion layer outer wall 1 and the prefabricated outer wall panel 3, and arranging an inclined support embedded nut 7 in the conversion layer cast-in-place surface 6 to facilitate stable support of the prefabricated outer wall panel 3 in the construction process.
The sealing structure of the PC outer wall and the cast-in-place floor transfer floor comprises the following process steps:
1) Construction is carried out strictly according to a design drawing, and channel steel support can be installed after the finished concrete strength of the conversion layer reaches 2MPa before an outer formwork of the outer wall is dismantled;
2) when the prefabricated external wall panel 3 is installed, the bin is sealed by using the base slurry, and when the external wall panel is hoisted and adjusted, the external wall panel needs to be slowly lowered, so that the accurate position and the integrity of the outer elastic rubber-plastic strip 5 are ensured;
3) before grouting, the elastic rubber-plastic strip is checked from the outer side to have no damage or gap, and grouting is carried out without slurry leakage, if slurry leakage is found, the elastic rubber-plastic strip is used for plugging immediately, and grouting is carried out again until the elastic rubber-plastic strip is fully filled.
The assembly type building is a necessary trend of future development, quality control and grouting quality control of outer wall joints are key and difficult points of the assembly type building, and the improvement measures that channel steel supports the rubber-plastic strips are adopted in the conversion layer, so that the grouting contact area of the outer wall and the cast-in-place conversion layer is ensured, the slurry leakage phenomenon is greatly reduced, the grouting quality is ensured, and the quality and the durability of the whole assembly type building are improved to a certain extent.
