Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically, it relates to a factory roof structure. Background Technology

[0002] The service life of commonly used color steel plate factory roofs is clearly stipulated according to the usage standards. If used beyond the expiration date, problems such as rain leakage, outdated ventilation facilities, and poor heat insulation may occur.

[0003] The proposed solution is to directly replace the old corrugated steel sheets with new ones to address the issue of the expired roof of the corrugated steel sheet factory. However, since the production line below needs to operate normally, there are significant safety hazards associated with working above and below. According to existing structural standards, the roof beams or purlins of the corrugated steel sheet factory need structural reinforcement. The workshop has numerous and complex equipment facilities, limited space, and the difficulty and high risk of overlapping reinforcement work make this extremely challenging. Traditional corrugated steel sheet factory roofs often use ventilators, which are quite large. If photovoltaic panels are installed on the factory roof, it would affect the duration of sunlight exposure for the panels. Furthermore, with the existing corrugated steel sheet roof, the air exchange between indoors and outdoors via ventilators results in slow exhaust of polluted indoor air, leading to insufficient timely removal of stale indoor air.

[0004] Therefore, developing a factory roof structure that can be applied to the repair of existing factory roofs without affecting the work of employees inside the factory, and can also be applied to the construction of new factory buildings to improve indoor and outdoor ventilation, is an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a factory roof structure that can be used for the repair of existing factory roofs without affecting the work of employees inside the factory; it can also be used for the construction of new factories to improve the ventilation between the inside and outside of the factory.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] This utility model proposes a factory roof structure, including:

[0008] A roof assembly unit extends along a first direction of the factory roof. There are multiple roof assembly units, and multiple roof assembly units are sequentially spliced ​​along a second direction of the factory roof to form a factory roof structure.

[0009] The roof assembly unit includes a first roof layer, a second roof layer, an exhaust end, and an air inlet end; the first roof layer is located near the interior of the building, and the second roof layer is located near the exterior of the building; the air inlet end is formed on the first roof layer and communicates with the interior of the building; the exhaust end is formed on the second roof layer and communicates with the exterior of the building; air inside the building flows from the air inlet end along the airflow passage formed between the first roof layer and the second roof layer to the exhaust end and is discharged outside the building.

[0010] In some embodiments of this application, the area where the exhaust end is located on the second roof layer is at a higher height than other areas of the second roof layer;

[0011] The exhaust end is formed on the second roof layer at the first end of the airflow passage.

[0012] In some embodiments of this application, there are multiple air inlets, and the multiple air inlets are disposed on the first roof layer along the first direction;

[0013] The air intake end is formed on the first roof layer at the second end of the airflow passage.

[0014] In some embodiments of this application, a sealing portion is provided at the first end of the airflow passage, and the sealing portion is connected between the first roof layer and the second roof layer;

[0015] The second end of the airflow passage abuts against the closed portion of the adjacent airflow passage.

[0016] In some embodiments of this application, the exhaust end is configured to have an extension along the height direction.

[0017] In some embodiments of this application, photovoltaic panels are extended from the second roof layer.

[0018] In some embodiments of this application, the first roof layer includes a corrugated steel tile roof, and a plurality of protrusions are formed on the corrugated steel tile roof. The protrusions extend along a first direction and are disposed on one side of the corrugated steel tile roof near the second roof layer, and the plurality of protrusions are spaced apart.

[0019] In some embodiments of this application, a reinforcement portion is also included, which is connected between the adjacent roof assembly units.

[0020] In some embodiments of this application, the reinforcing part includes a first horizontal reinforcing part, a second horizontal reinforcing part, and a vertical reinforcing part;

[0021] The first horizontal reinforcement is connected between the second roof layer and the enclosed portion of the adjacent roof assembly unit;

[0022] The second horizontal reinforcement is connected between the enclosure and the first roof layer;

[0023] The vertical reinforcement section is connected between the first horizontal reinforcement section and the second horizontal reinforcement section.

[0024] In some embodiments of this application, the roof assembly unit is provided to protrude outward from the middle of the house.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are:

[0026] This application is applicable to the construction of new factory buildings, where the factory roof structure described in this application can be directly adopted, resulting in improved waterproofing and heat insulation. A double-layered roof is formed between the first and second roof layers, allowing for air circulation. Stale air from the roof enters the airflow passage through the air inlet on the first roof layer and is then discharged through the exhaust outlet on the second roof layer. This effectively removes the gas, and some residual heat is transferred to the air in the airflow passage through the second roof layer, effectively heating the stale air discharged through the exhaust outlet. This allows the stale air to be quickly discharged outside the building, effectively adding active exhaust power to the indoor air inlet and improving the exchange of fresh air indoors.

[0027] This application applies to the simple renovation of existing corrugated steel roofs that are due for repair and replacement. The existing corrugated steel roof and other structures are removed, and the existing roof serves as the first roof layer. Only simple renovation and reinforcement of the first roof layer are required, which will not affect normal production activities within the factory, significantly reducing safety hazards. Adding a second roof layer on top of the first roof layer will also not affect production activities within the building, and the second roof layer itself is waterproof, forming a double-layer waterproof structure with the original first roof layer. The double-layer structure between the first and second roof layers provides superior heat insulation, effectively reducing the impact of heat conduction from the roof structure on indoor temperature.

[0055] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0056] Some embodiments of this application relate to a factory roof structure, such as Figure 4 , Figure 5 As shown, the structure includes a roof assembly unit 100, which extends along a first direction 170 of the factory roof. Multiple roof assembly units 100 are assembled along a second direction 180 of the factory roof to form the factory roof structure.

[0057] like Figure 4 As shown, the first direction 170 is defined as the width direction of the factory roof. The second direction 180 is defined as the length direction of the factory roof.

[0058] like Figure 2 , Figure 3 As shown, the roof assembly unit 100 includes a first roof layer 110, a second roof layer 120, an exhaust end, and an air inlet end 140.

[0059] The first roof layer 110 is located closer to the interior of the building. The second roof layer 120 is located closer to the exterior of the building. An airflow passage 130 is formed between the first roof layer 110 and the second roof layer 120.

[0060] The airflow passage 130 is provided to extend along the second direction 180.

[0061] An air intake 140 is located on the first roof layer 110. An exhaust 140 is located on the second roof layer 120. Both the air intake 140 and the exhaust 140 are connected to the airflow passage 130.

[0062] Air inside the house can enter the airflow passage 130 through the air inlet 140, and the air in the airflow passage 130 can flow to the outside of the house through the exhaust end.

[0063] Specifically, in order to ensure that the airflow has a longer flow path within the airflow passage 130, the air inlet 140 needs to be located on the first roof layer 110 at the second end of the airflow passage 130. The exhaust end needs to be located on the second roof layer 120 at the first end of the airflow passage 130.

[0064] Thus, the air inside the house enters from the second end of the airflow passage 130 and flows out from the first end of the airflow passage 130.

[0065] like Figure 1 As shown, the second roof layer 120 is the top layer of the factory roof and is in direct contact with the outdoor air. Under sunlight, the temperature of the second roof layer 120 rises, and some of the heat absorbed by the second roof layer 120 is conducted into the airflow passage 130, thus raising the air temperature within the airflow passage 130. The air temperature within the airflow passage 130 is higher than the temperature inside the building, causing the heated gas to expand. The expanded, low-density gas is then discharged outside the building through the exhaust end. This creates an accelerated flow channel within the airflow passage 130. This allows the gas within the airflow passage 130 to be quickly discharged, and the gas inside the building to be quickly replenished within the airflow passage 130, thereby accelerating the gas exchange rate between the inside and outside of the building, providing the power for active exhaust, and improving the fresh air replacement effect inside the building.

[0066] like Figure 1 , Figure 2 , Figure 3 As shown, in order to increase the gas discharge velocity through the exhaust end, the exhaust end is configured to have an extension 131 along the height direction.

[0067] Specifically, extension 131 can take the form of a chimney.

[0068] Because the exhaust end includes an extension section 131 of a certain height, a channel is formed within the extension section 131 that accelerates the flow of expanding low-density gas, thus creating a chimney effect. The expanding low-density gas is accelerated and discharged through the extension section 131, thereby providing power for the exhaust.

[0069] To further increase the exhaust velocity of the gas in the airflow passage 130, the exhaust end is positioned at a height higher than the height of other areas of the second roof layer 120.

[0070] Because the exhaust end is located at a height of 120 on the second roof layer, the gas in the airflow passage 130 can be better discharged through the exhaust end.

[0071] In some embodiments of this application, the roof assembly unit 100 protrudes outward from the center of the building. An exhaust end is located at the protruding point in the center of the roof leveling unit.

[0072] Specifically, along the first direction 170, the exhaust end is located at the middle position of the roof assembly unit 100.

[0073] The factory roof structure, which is formed by splicing together roof assembly units 100 that protrude outward from the middle of the building, allows rainwater entering the extension section 131 to be discharged from both ends of the roof assembly units 100 along the first direction 170.

[0074] There can be multiple air inlets 140, which are spaced apart along the first direction 170 on the second end of the airflow passage 130. This allows air from inside the house to quickly enter the airflow passage 130 along the first direction 170.

[0075] The roof assembly unit 100 also includes a sealing section 150, which is connected between the first roof layer 110 and the second roof layer 120. The sealing section 150 is used for connection within the same roof assembly unit 100, thereby achieving the sealing of the first end of the airflow passage 130.

[0076] The second end of the airflow passage 130 can be open, and the second end of the airflow passage 130 can be closed by abutting against the closed part 150 of the adjacent roof assembly unit 100.

[0077] In other embodiments of this application, a sealing portion 150 may be provided at the second end of the airflow passage 130, connecting the first roof layer 110 and the second roof layer 120. Alternatively, a sealing portion 150 may be provided at both the first and second ends of the airflow passage 130.

[0078] To provide support for the second roof layer 120, a reinforcement section 160 is provided between the first roof layer 110 and the second roof layer 120.

[0079] Since the exhaust end is provided with an extension section 131 along the height direction, the gravity at this point is greater than that at the second roof layer 120. Therefore, the reinforcement part 160 is connected to the sealing part 150.

[0080] Specifically, the reinforcement part 160 includes a first horizontal reinforcement part 161, a second horizontal reinforcement part 162, and a vertical reinforcement part 163.

[0081] The first horizontal reinforcement 161 is connected between the second roof layer 120 and the enclosure 150 of the adjacent roof assembly unit 100.

[0082] The second horizontal reinforcement 162 is connected between the enclosure 150 and the first roof layer 110.

[0083] The vertical reinforcement part 163 is connected between the first horizontal reinforcement part 161 and the second horizontal reinforcement part 162.

[0084] In some embodiments of this application, photovoltaic panels are provided on the second roof layer 120 in order to integrate photovoltaic power generation function within the factory roof structure.

[0085] The first roof layer 110 includes a corrugated steel tile roof, on which a plurality of protrusions 111 are formed. The protrusions 111 extend along the first direction 170 and are disposed on the side of the corrugated steel tile roof near the second roof layer 120.

[0086] Several protrusions 111 are spaced 180 degrees apart along the second direction on the corrugated steel roof.

[0087] Since multiple protrusions 111 are provided on the corrugated steel roof extending along the first direction 170, the protrusions 111 can play a certain role in waterproofing rainwater entering the airflow passage 130 from the extension section 131.

[0088] Existing factory buildings mostly use ventilators on corrugated steel roofs for indoor and outdoor ventilation. When the corrugated steel roofs reach their service life and need maintenance and replacement, according to existing structural standards, it is necessary to reinforce the top beams or purlins or directly replace them with new corrugated steel sheets. Since the production line below needs to operate normally, there are significant safety hazards in working up and down. The equipment and facilities inside are numerous and complex, the footing space is limited, and the reinforcement construction is extremely difficult and has a high risk factor.

[0089] To address the aforementioned issues, the existing corrugated steel roof, which is due for repair and replacement, can be simply renovated. The louvers and other structural elements can be removed, and the existing corrugated steel roof can be used as the first roof layer 110 of this application. The factory roof structure of this application can then be used to modify the existing factory building. This construction method has virtually no impact on the production line operations below, and safety hazards are significantly reduced during reinforcement and the installation of the second roof layer 120. The photovoltaic panels themselves are waterproof, forming a double layer of waterproofing with the original first roof layer 110. They can also absorb some sunlight and generate electricity to power the workshop, achieving a green and low-carbon effect. The double layer between the first roof layer 110 and the second roof layer 120 provides superior heat insulation, effectively reducing the impact of heat conduction from the roof structure on the indoor temperature.

[0090] Furthermore, the roof structure described in this application can be directly adopted during the construction of a new factory building, which improves both waterproofing and heat insulation. A double-layer roof is formed between the first roof layer 110 and the second roof layer 120, allowing for air circulation. Stale air from the roof enters the airflow passage 130 through the air inlet 140 on the first roof layer 110, and then exits through the exhaust end on the second roof layer 120, effectively expelling the gas. After the photovoltaic panels absorb some sunlight to generate electricity, some residual heat is still transferred to the air in the airflow passage through the photovoltaic panels, which is equivalent to heating the stale air discharged through the exhaust end, thus creating a chimney effect. This causes the exhaust air to form an acceleration channel as it enters the extension section 131, which also adds active exhaust power to the indoor air inlet 140, improving the exchange of fresh air indoors.

[0091] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0092] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0093] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
