Description

Shelter structure of building opening

The invention relates to building materials; in particular, it refers to a shielding structure for building openings with drainage and pressure relief devices.

For building openings such as windows or door panels, windows must have good operability, sound insulation, wind resistance, and water resistance. Therefore, airtight windows are often used in shops. In an airtight window with a sliding rail design that is pulled by the user to open or close, the window frame is provided with parallel rails, and two windows are provided with staggered and relatively translational positions. Combine to close or connect the space between the indoor and outdoor sides of the building. The two windows are sealed to prevent wind and rain from the outdoor side from being injected into the indoor space.

However, when the wind and rain are too strong, the pressure on the outdoor side is greater than the pressure on the indoor side. This pressure difference is likely to cause wind and rain to enter the indoor space through the window frame and the gap between the two windows, resulting in indoor humidity and water leakage. The design of the shielding structure of the opening still needs to be improved.

In view of this, the object of the present invention is to provide a shielding structure for building openings with a drainage and pressure relief device to prevent wind and rain from entering the indoor space through the window frame and the gap between the two windows.

In order to achieve the above-mentioned object, the present invention provides a building opening shielding structure including a window frame, and a front block and a rear block are relatively translationally arranged in the window frame; characterized in that: the window frame has A bottom frame, the bottom frame has at least one drainage groove; the front block has a first vertical frame, the first vertical frame has a first vertical surface; the rear block has a second vertical frame, the second vertical frame Has a second vertical surface facing the first vertical surface; the shielding structure of the building opening includes a sealing structure disposed between the first vertical surface and the second vertical surface, the sealing structure and the first vertical surface And the second vertical surface surrounds a space; wherein at least one of the first vertical surface of the front block and the second vertical surface of the rear block has at least one perforation, and the at least one perforation communicates with the space and the drainage groove .

The effect of the present invention is that when the wind and rain are too heavy, by introducing wind or rain water into the space and draining it through the perforation, it can avoid the excessive pressure difference between indoor and outdoor, causing wind and rain to penetrate through the window frame and the gap between the two windows. The indoor side space leads to humidity and water leakage in the room, thereby achieving a good sealing effect.

In order to explain the present invention more clearly, a preferred embodiment is described in detail in conjunction with the drawings as follows. Please cooperate with FIG. 1 to FIG. 4, which is a preferred embodiment of the shielding structure 1 for building openings of the present invention, including a window frame 10, a front block 20, a rear block 30 and a sealing structure 40, wherein the window frame 10 It is a rectangular body and includes a bottom frame 12 at its bottom.
