[0006] Preferably, angle codes are fixedly installed around the curtain wall, and the curtain wall is locked to the keel through bolts penetrating the angle codes.

[0007] Preferably, a horizontal section is arranged at the central position of the supporting strip, and through holes are equidistantly arranged on the horizontal section.

[0008] Preferably, mounting holes with the same inner diameter as the through holes are arranged on the angle codes.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figures 1-6The utility model provides a technical scheme: a building curtain wall structure for sponge city with high -efficient drainage function, including curtain wall 1 of a plurality of in turn arrange and install on keel, the four around of curtain wall 1 is fixedly installed with angle code 2, curtain wall 1 is locked on keel through bolt and penetrates angle code 2, the keel is prior art, not shown in the drawing, the modular installation of frame type curtain wall keel can shorten the construction period, improve engineering quality and guarantee construction safety, and the adjacent curtain wall 1 between installation has the supporting strip 3 with foam strip 4, and the foam strip 4 is cylindrical structure, and the central position of supporting strip 3 is equipped with horizontal section, and the horizontal section is equipped with through -hole 8 at equal intervals, and the angle code 2 is equipped with the installation hole same with the inner diameter of through -hole 8, and the advantage that such setting is that supporting strip 3 can be fixedly installed on the angle code 2 of curtain wall 1 through bolt, and the central position of the both sides of supporting strip 3 is integrally formed with the clamping cavity for accommodating foam strip 4, and the advantage that such setting is to ensure that the construction personnel is consistent in depth when installing foam strip 4, and the appropriate installation depth is easily determined according to the position of supporting strip 3, when foam strip 4 is installed consistently in depth, can provide uniform sealing interface, reduce the uncertainty in the construction process, so that the entire sealing area has no weak link. For example, in terms of preventing rainwater leakage, uniform foam strip installation can ensure that rainwater flowing on the surface of curtain wall 1 will not find a leakage path due to inconsistent sealing depth. The clamping cavity position of supporting strip 3 is equipped with arc section 7 matched with foam strip 4, supporting strip 3 has a certain elasticity, the both ends of arc section 7 are respectively equipped with first bending section 5 and second bending section 6, the end of first bending section 5 is inclined to extend to be connected with supporting strip 3, and the connection is smoothly transitioned with rounded corners, the end of supporting strip 3 extends to the side wall of curtain wall 1 in the horizontal direction to interfere with the side wall of curtain wall 1, so as to intercept rainwater seeping into the gap between adjacent curtain walls 1, the setting of first bending section 5 can make the both ends of supporting strip 3 interfere with the side wall of curtain wall 1 through the elastic potential energy of itself, under certain pressure, a small amount of rainwater may seep into the gap between adjacent curtain walls 1, which is intercepted by supporting strip 3 and falls by its own weight.
