The assembly type concrete expression form is the disassembly design of the component, the factory manufacture of the component and the field assembly. The assembly of the assembly type components and the plugging of the horizontal seam become the problems to be solved.
The splicing and plugging of the prior prefabricated external wall panel component comprises plugging of a horizontal seam parallel to a wall body. Fig. 1 is a schematic view of a waterproof structure of a horizontal seam structure of a known prefabricated external wall panel. A horizontal seam is arranged between the prefabricated part and the concrete cast-in-place part below the prefabricated part, once rainwater breaks through the backing strip and the waterproof sealant plug at one end outside the back horizontal seam chamber and the waterproof sealant and the water stop strip plug at one end inside the back horizontal seam chamber, the original waterproof plugging structure collapses, and the plugging rainwater easily penetrates into the chamber along the horizontal seam. And in addition, the rabbet horizontal joint is blocked, and a schematic diagram of a known waterproof structure of the rabbet structure of the prefabricated external wall panel is shown in figure 2. The construction shown in fig. 2 is essentially the same as that shown in fig. 1, the only difference being that the waterproof seal at the outdoor end is positioned lower than the indoor end. The tongue-and-groove horizontal joint has the advantages that short supporting members protruding out of the wall body are too small, complicated in construction, not easy to stack and easy to damage.
The known structures for waterproofing the joints between the prefabricated elements and the underlying cast-in-place concrete portion have the inconveniences and problems described above.

In order to achieve the above object, the technical solution of the present invention is:
the utility model provides an assembled side fascia recess formula horizontal joint waterproof construction, includes that the horizontal joint port of leaning on the outdoor side between the cast-in-place part of outer wallboard prefabricated component and below sets up recess, its characterized in that:
the groove penetrates into the port of the horizontal seam on the outdoor side for a certain distance, the upper part of the groove is higher than the upper edge of the horizontal seam by a certain distance, and the lower part of the groove is lower than the lower edge of the horizontal seam by a certain distance;
wherein: the plugging structure of the horizontal seam port on the outdoor side is waterproof sealant and backing strip of the outer opening, and the plugging structure of the horizontal seam port on the indoor side is inorganic heat-insulating mortar and water-stop strip of the inner opening.
The utility model discloses an assembled side fascia recess formula horizontal joint waterproof construction can also adopt following technical measure to further realize.
In the groove type horizontal seam waterproof structure of the assembled external wall panel, the distance from the groove to the port of the horizontal seam on the outdoor side is not less than 30 mm.
According to the groove type horizontal seam waterproof structure of the assembled external wall panel, the height above the groove is more than or equal to 10mm higher than the upper edge of the horizontal seam.
According to the groove type horizontal seam waterproof structure of the assembled external wall panel, the height of the lower part of the groove is reduced by more than or equal to 10mm compared with the lower edge of the horizontal seam.
According to the groove type horizontal seam waterproof structure of the fabricated external wall panel, the groove notch is reserved in the range of the reinforcing steel bar protection layer.
After the technical scheme is adopted, the utility model discloses an assembled side fascia recess formula horizontal joint waterproof construction has following advantage:
1. the waterproof structure is simple and the construction is convenient;
2. the engineering quality is safe and reliable, and the waterproof performance of the groove type horizontal seam structure node is better;
3. the damage of the secondary carrying of the member is avoided, and the enclosing cost of the node is reduced.
Drawings
FIG. 1 is a schematic view of a waterproof structure of a horizontal seam structure of a known prefabricated external wall panel;
FIG. 2 is a schematic diagram of a waterproof structure of a tongue-and-groove joint structure of a known prefabricated external wall panel;
fig. 3 is the utility model discloses prefabricated wall panel recess formula horizontal joint structure waterproof construction schematic diagram.
In the figure: the construction method comprises the following steps of 1 cast-in-place concrete, 2 prefabricated parts, 3 backing strips, 4 waterproof sealants, 5 water stop strips, 6 inorganic heat-preservation mortar and 7 indoor elevation finished surfaces.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
Example 1
The utility model discloses an assembled side fascia recess formula horizontal joint waterproof construction, include that the horizontal joint port of the outdoor side of leaning on between 1 part of cast in situ concrete of outer wallboard prefabricated component 2 and below sets up the recess.
Referring to fig. 3, fig. 3 is a schematic view of a waterproof structure of a groove-type horizontal seam structure of a prefabricated external wall panel according to an embodiment of the present invention. As shown, the groove extends into the horizontal slit port on the outside of the chamber by a distance of 30 mm. The height above the groove is 10mm higher than the upper edge of the horizontal seam. The height of the lower part of the groove is 10mm lower than that of the lower edge of the horizontal seam.
Wherein: the plugging structure of the horizontal seam port on the outdoor side is waterproof sealant 4 and backing strip 3 of the outer opening, and the plugging structure of the horizontal seam port on the indoor side is inorganic heat-insulating mortar 6 and water-stop strip 5 of the inner opening. The notch of the groove is reserved in the range of the steel bar protection layer.
The utility model has the advantages of substantive characteristics and apparent technological progress, the utility model discloses an assembled side fascia recess formula horizontal joint waterproof construction is applicable to the outer wall nodal connection of assembly type structure. The structure principle is simple: the lining strip is filled, the outer part of the lining strip is sealed by waterproof sealant, and finally the sealant part ensures smooth transition with the rigidity of the component, and the anti-seismic performance is not greatly different from that of a cast-in-place structure. In actual use, rainwater on the outer wall is blocked by the waterproof sealant and the backing strip, and can flow down along the wall body and cannot enter the horizontal seam. Therefore, the groove type horizontal seam structure node can effectively prevent rainwater from entering the room. Relative to the tongue-and-groove horizontal seam and the horizontal seam node, the groove type horizontal seam structure node has better waterproof performance and convenient construction, so the quality is easy to control.
The above embodiments are provided only for the purpose of illustration, and not for the purpose of limitation, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention, which is defined by the claims.
