Description

Technical Field

[0001] This utility model relates to the technical field of roof ventilation and air permeability facilities. Background Technology

[0002] Roof ventilation is one of the design indicators of green buildings. It requires good ventilation to effectively regulate indoor temperature and humidity, remove harmful gases and heat, extend the service life of the roof, and improve the comfort and experience of residents or producers.

[0003] Depending on the structural type of the device, ventilation devices can be divided into: natural ventilation through roof windows, rotary ventilation through turbine ventilators, and ventilation through overhead ventilation layers. Among them, natural ventilation through roof windows refers to opening windows on the side or top of a sloping roof and using thermal pressure difference to create air convection. This type of ventilation does not rely on a power system and is therefore the most widely used.

[0004] For example, Chinese patent document CN202421153157.3 discloses a natural ventilator for a house. This ventilator is installed on the roof, with air outlets on both sides of the roof ridge tiles. The ventilator is positioned above the air outlets, and it solves problems such as heat dissipation and air circulation by constructing an L-shaped air outlet path. However, this type of ventilator suffers from rainwater seepage during rainy weather. Therefore, how to improve the water seepage and leakage problem of existing ventilators during rainy weather is a major technical challenge. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a green building roof ventilation and air permeability device to solve the problems of water seepage and leakage in existing ventilators during rainy days.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A green building roof ventilation and air-permeable device is characterized by: a vertical column passing through the roof window area, the lower end of which is fixed to a steel beam, and a horizontal bar fixedly connected to the upper end. This horizontal bar is arranged transversely along the window area, and an aluminum-zinc coated steel plate is laid on top of the horizontal bar, the projected area of ​​which is larger than the area of ​​the window area; a herringbone-patterned ventilation net is fixed between the horizontal bar and the middle section of the column; galvanized flashing steel sheets are fixed around the window area to form a waterproof edge; and a folding... The device features a functional double-folding rod, one end of which is welded and fixed to a column, and the other end is welded and connected to an L-shaped rod. The outer side of the L-shaped rod is covered with an aluminum-zinc coated steel plate. An electric push rod is installed between the outer rod and the crossbar of the double-folding rod. In the retracted state of the electric push rod, the two L-shaped rods on both sides are closed, and the lowest point of the closed L-shaped rod is spaced from the roof. In the extended state of the electric push rod, the two L-shaped rods on both sides are unfolded, and the gap between the L-shaped rod and the roof gradually decreases.

[0008] Furthermore, longitudinal bars I are welded in the area between the crossbars. The longitudinal bars I consist of three rows, left, middle and right, forming a grid structure between the crossbars and the longitudinal bars I.

[0009] Furthermore, a longitudinal rod II is provided in the middle of the column, which is located above the heat-insulated color steel roof, and the upper edge of the zinc-plated color steel sheet is fixedly connected to the longitudinal rod II.

[0010] Furthermore, longitudinal bars III are provided between the L-shaped members on the same side and connected as a whole, and the aluminum-zinc coated steel plate is built on the outside of the L-shaped members and longitudinal bars III.

[0011] Furthermore, the crossbar is a herringbone-shaped square steel pipe with its middle section bent upwards.

[0012] Furthermore, the column is made of galvanized steel pipe.

[0013] Furthermore, the aluminum-zinc coated plate is at least 1 mm thick and is fixed by screw fastening.

[0014] Furthermore, the breathable mesh is an alkali-resistant mesh made of hydrophobic material or a stainless steel mesh.

[0015] Furthermore, the aluminized zinc color plate has an extended flange.

[0016] Furthermore, the column is an electrically telescopic pole with height adjustment function.

[0017] The beneficial effects of this utility model are:

[0018] The implementation of this technology can create a ventilation window with a width of about 0.5 meters on a typical roof surface. This ventilation window has different states in sunny and rainy weather. The adjustment of this state is achieved by the action of an electric push rod, which has the technical advantage of one-button operation.

[0019] The implementation of this technology allows for the formation of two waterproof caps at the top of the window during rainy weather, effectively solving the problems of water seepage and leakage. Attached Figure Description

[0032] This embodiment will be described in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 3 The structural principle and implementation process of the roof ventilation and air permeability device for this green building are explained in detail.

[0033] Example 1

[0034] The original roof structure of the building was as follows: Figure 1 As shown, this type of roof only provides insulation by using insulated color steel on the top and does not provide ventilation.

[0035] This device is installed on a roof consisting of steel beams 01 and insulated color steel roofing 02. Specifically, windows are made in the existing roof, and the windows are reinforced with support members 03. Columns 10 are welded or riveted to the windows. These columns are preferably made of galvanized steel pipes. There is one column on each side, and the columns extend upwards from the steel beams of the roof. The top of the column 10 extends to the outside of the roof and is at least 50 centimeters away from the roof. There are multiple such columns.

[0036] An open space is provided between the aforementioned steel beam 01 and the insulated color steel roof 02, and the open space is preferably 20 cm high.

[0037] For ease of description, in Figure 2 In this paper, vertical (Z-axis), horizontal (X-axis), and longitudinal directions are defined.

[0038] A herringbone-shaped crossbar 20 is welded and fixed to the top of the column 10, making the two columns a single unit. An aluminum-zinc coated steel plate 21 is laid on top of the crossbar, preferably with a thickness of 1 mm. The plate is fixed with screws, and the outer edge of the fixed aluminum-zinc coated steel plate 21 is larger than the aforementioned window width, forming a rainproof cover with a cap-like structure.

[0039] Furthermore, longitudinal bars I 22 are welded in the area between the aforementioned horizontal bars 20, consisting of three rows on the left, middle and right. The horizontal bars and longitudinal bars I form a grid structure, which has higher strength and also makes the overall rainproof strength higher.

[0040] A longitudinal rod II 30 is installed in the middle of the aforementioned column 10. This longitudinal rod II 30 is located approximately 10 centimeters above the insulated color steel roof. A galvanized flashing panel 31 is installed between the longitudinal rod II and the insulated color steel roof, and is fixed by weather-resistant sealant. Screws are used to further secure the longitudinal rod II and the galvanized flashing panel. After the galvanized flashing panel is installed, it forms a waterproof barrier of approximately 10 centimeters on both sides of the window opening, preventing rainwater from directly splashing into the window.

[0041] Furthermore, the galvanized flashing sheet also encloses the longitudinal end of the window, forming a 10-centimeter waterproof barrier around the window to prevent rainwater from splashing directly into the window.

[0042] A breathable mesh 40 is fixedly installed between the horizontal bar 20 and the middle section of the two side columns. This breathable mesh is made of a hydrophobic material, such as alkali-resistant mesh or stainless steel mesh. The middle part of the breathable mesh is suspended from the horizontal bar, specifically at the highest point of the horizontal bar. The two sides of the breathable mesh are fixed to the longitudinal bar II or the middle section of the columns using screws. Figure 2In the middle, the breathable mesh is arranged in a herringbone pattern. This arrangement can prevent the accumulation of dust and dead insects on the breathable mesh, that is, it has a certain self-cleaning effect.

[0043] A folding rod 50 with a folding function is also installed on the outside of the column at the longitudinal rod II. This folding rod consists of an inner rod and an outer rod that are hinged to each other. One end of the folding rod 50 is welded and fixed to the column 10, and the other end is welded and connected to an L-shaped rod 51. An electric push rod 52 is installed between the outer rod of the folding rod and the aforementioned crossbar. That is, both ends of the electric push rod are mechanically connected to the crossbar and the folding rod by hinges. It is easy to understand that in the retracted state of the electric push rod, the L-shaped rods on both sides are closed, and the lowest point of the closed L-shaped rod 51 is about 10 cm away from the roof. In the extended state of the electric push rod, the two L-shaped rods are unfolded. In the unfolded state, the gap between the L-shaped rod 51 and the roof gradually decreases until they come into contact.

[0044] The L-shaped rods 51 on the same side are connected as a whole by the longitudinal rod III, and an aluminum-zinc coated steel plate 53 is built on the outside of the frame between the L-shaped rods and the longitudinal rod III to form a weather-resistant outer shell. The outer shells on both sides can be opened and closed by the action of the electric push rod. In the closed state, it forms a cap-shaped structure, which is the second rainproof structure. In the open state, it increases the top area for ventilation and improves the ventilation effect.

[0045] Furthermore, the aluminum-zinc coated steel sheet 53 has an extended flange extending outward from the outer edge of the low point of the L-shaped member 51 to form a drip edge, which can improve the splash protection effect of rainwater.

[0046] The implementation of this embodiment fully considers the different usage scenarios of low ventilation and high waterproofing in summer rainy conditions and high ventilation in sunny conditions. The two different modes can be switched by using an electric push rod.

[0047] Example 2

[0048] refer to Figure 4 By replacing the aforementioned support column with an electric telescopic rod 60 that has height adjustment, the ventilation device can be adjusted in the height direction. In winter, the ventilation opening can be lowered to control the ventilation volume.

[0049] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
