The utility model relates to building structure engineering technical field especially is related to a tiger window waterproof joint. The utility model discloses a tiger window waterproof joint, include: roof, the inside column of window, its bottom is fixedly connected with roof, the outside column of window is located the outside of inside column of window, first waterproof support layer is fixedly laid in the outer surface of roof, the outer surface fixed laying of first waterproof support layer has first waterproof layer, the bottom between outside column of window of first waterproof support layer has the gap for first waterproof layer passes, second waterproof support layer is fixed on the outside of outside column of window, the surface of second waterproof support layer is laid with second waterproof layer. Through the layered setting and gap cooperation of double -layer waterproof system, rainwater penetration path is blocked, prevents rainwater from invading roof structure, has improved the reliability and durability of waterproof system significantly, has prolonged the service life of waterproof system.

This utility model relates to the field of construction mold technology and discloses a dormer window forming mold, comprising: a receiving base; a prefabrication mechanism disposed on top of the receiving base, the prefabrication mechanism being used for prefabricating the dormer window frame; and an external vibration mechanism disposed on the receiving base, the external vibration mechanism being used for externally vibrating the concrete. This utility model, through the overall design of the prefabrication mechanism, with the cooperation of a fixed mold and a movable template, can prefabricate the dormer window frame inside the forming cavity. The dormer window frame is produced in a standardized factory, allowing for precise control of concrete strength and rebar position, reducing on-site construction errors, thereby improving the overall load-bearing capacity of the dormer window structure, reducing the risk of roof deformation due to openings, avoiding weather interference with dormer window frame construction, and avoiding the safety issues caused by assembling and disassembling templates at heights.

This invention discloses a side-suction ventilation louver with a thermal pressure enhancement effect, comprising: a truss, a first protective panel structure, a roof structure, and a drainage protective panel structure. The roof structure includes a light-transmitting protective panel inclinedly disposed at the top of the truss, and a second protective panel structure disposed on the outer side of the truss and connected to the edge of the light-transmitting protective panel. The second protective panel structure is fixedly connected to the first protective panel structure through a transverse connector. The roof structure and the first protective panel structure enclose a ventilation chamber. The second protective panel structure includes an inclined surface and an inwardly bent vertical surface. The vertical surface forms a cantilever structure at the upper edge of the first protective panel structure to shield the exhaust vent, eliminating the possibility of rainwater backflow from a structural principle perspective.
