Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of a usage state of the present invention.
In the figure: 1. the rubber strip comprises a rubber strip body, 11, a water splitting strip, 12, a sealing strip, 13, a connecting piece, 131, a connecting transverse plate, 132, a connecting vertical plate, 14, a water baffle plate, 141, a water baffle vertical plate, 142, a water baffle transverse plate, 15, a rib plate, 16, an equal-pressure cavity, 161, an opening, 2, an upper protective edge, 3 and a lower protective edge.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
In the embodiment shown in fig. 1, the waterproof rubber strip for the unitized glass curtain wall comprises an integrally formed rubber strip body 1 with an a-shaped cross section, wherein a water splitting strip 11 and a sealing strip 12 are fixedly connected with each other at the top edge of the rubber strip body 1, and a rib plate 15 is connected between the water splitting strip 11 and the sealing strip 12. The top of adhesive tape body 1 is equipped with connecting piece 13, and connecting piece 13 is the boss that the cross-section is the T style of calligraphy, and connecting piece 13 includes the perpendicular connection connecting diaphragm 131 and connects riser 132, connects riser 132 base and adhesive tape body top and links to each other. One side of the bottom of the connecting piece 13, which is close to the water splitting strip 11, is provided with a water baffle 14, the cross section of the water baffle 14 is L-shaped, the water baffle 14 comprises shorter water baffle vertical plates 141 and longer water baffle transverse plates 142, one side of each water baffle transverse plate 142 is vertically connected with the corresponding water baffle vertical plate 141, and the other side of each water baffle transverse plate 142 is vertically connected with the bottom of the corresponding connecting vertical plate 132. The lower parts of the water splitting strip 11 and the sealing strip 12 are arc-shaped, the concave surfaces of the arc-shaped parts face one side of the water baffle 14, the arc-shaped curvature of the water splitting strip 11 is smaller than that of the sealing strip 12, and the length of the water splitting strip is larger than that of the sealing strip. The lower part of the water splitting strip 11, the lower part of the sealing strip 12 and the rib plate 15 enclose an unclosed equal pressure cavity 16, and an opening 161 of the equal pressure cavity 16 is arranged between the bottom edge of the water splitting strip 11 and the bottom edge of the sealing strip 12.
When installing waterproof rubber strip, as shown in fig. 2, install upper safe edge 2 and lower safe edge 3 respectively on the upper and lower crossbeam of two adjacent glass curtain wall plate pieces at first, arrange waterproof rubber strip's breakwater 13 in the outside again, be about to split water strip 11 and arrange the outside in to insert T style of calligraphy boss in the T style of calligraphy recess of upper safe edge 2, accomplish the adhesive tape installation promptly. After the upper plate and the lower plate of the curtain wall are installed, the height dimension of the adhesive tape is larger than the gap between the plates, so that the water splitting strip and the sealing strip of the adhesive tape are always in contact with the lower protective edge, the adhesive tape is kept to have certain elasticity and compressive stress, and the sealing requirement is met.
When outdoor rainwater invades, most of rainwater is blocked by the water splitting strips 11 at the outermost sides of the waterproof rubber strips, and the rainwater is guided to the outdoor. Due to the arrangement of the equal-pressure cavity 16, pressure difference is eliminated, and rainwater cannot easily cross the water splitting strips to enter the equal-pressure cavity. Even if a small amount of rainwater permeates into the equal-pressure cavity, the rainwater is difficult to cross the sealing strip and enter the interior of the curtain wall because the elastic sealing strip 12 is tightly attached to the lower protective edge 3. The sealing strip can also guide rainwater to the opening 161, and the pressure in the isobaric cavity is kept consistent with the outdoor pressure all the time, so that the sealing performance is ensured. The water baffle 14 blocks the gap at the joint of the waterproof rubber strip and the upper protective edge 2, and prevents rainwater from permeating from the gap.
