A water guide 6 for receiving seeping rainwater is provided below the transverse gap 4. A first connecting piece 7 is provided in the water guide 6. The first connecting piece 7 is fixedly connected to the second pressing piece 5 by a fastener 8. The first connecting piece 7 is tensionally connected to the water guide 6. The present invention arranges a second pressing piece 5 above the transverse gap 4 to prevent rainwater from penetrating, thereby improving the waterproof effect, and arranges a first connecting piece 7 in the water guide groove 6, and connects the first connecting piece 7 and the second pressing piece 5 through a fastener 8 to form an effective connection. In addition, the first connecting piece 7 is tensionedly connected to the water guide groove 6, eliminating the gap between the first connecting piece 7 and the water guide groove 6, so that the first connecting piece 7 is firmly connected in the water guide groove 6, and there is no need to use a wall-breaking bolt connection method to connect the first connecting piece 7 and the water guide groove 6, which will not cause structural damage to the water guide groove 6, thereby ensuring the waterproof effect while improving the structural strength.
