Fig. 1 shows the overall structure of the waterproof structure of the assembled external wall panel joint of the present invention.
Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses assembled side fascia seam crossing waterproof construction, including cast-in-place grout blanket 2 in floor 200 and side fascia 100's seam, the lower surface of grout blanket 2 and floor 200 contact is the slope, and the slope is close to the one end downward sloping in the side fascia 100 outside, buries the drain pipe 5 that one end butt joint extends floor 200 surface in the floor 200 underground in slope low side, the other end.
Fill the seam between floor 200 and the side fascia 100 through grout blanket 2, the bottom of grout blanket 2 is equipped with the slope for the infiltration can be because of gravity backward flow to the outside of side fascia 100, and discharge through the drain pipe 5 of locating the slope low side, play certain water-proof effects, has blocked water infiltration in to the wall through the drain pipe 5 page or leaf that sets up simultaneously.
Further, the upper surface of grout blanket 2 is equipped with the arch 6 of inlaying in side fascia 100, through this arch 6 extension infiltration route, and the arch 6 that upwards sets up can play the effect of certain blocking infiltration route.
Wherein, the vertical grout sleeve 1 that is used for cast-in-place grout blanket 2 that buries underground in side fascia 100, be equipped with two grout mouths on grout sleeve 1's the lateral wall, two grout mouths are located different height positions respectively, when the slip casting, by grout mouth of below to the interior grout shape grout blanket 2 of pouring into of seam, show when the grout is oozed by the grout mouth of top and irritate fully, side fascia 100's vertical reinforcing bar is inserted and is located grout sleeve 1 in, carry out certain limiting displacement to grout sleeve 1.
The end parts of the grouting layer 2, which are positioned at the inner side and the outer side of the external wall panel 100, are respectively filled with the blocking materials 7 positioned in the joint, and the end parts of the joint are blocked by filling the blocking materials 7 at the inner end and the outer end of the joint, so that grouting material is poured into the formed cavity to form the grouting layer 2, and the sealing and waterproof effects of the joint are also improved.
