Description

Technical Field

[0001] The present invention relates to the technical field of building construction engineering, in particular to a building roof structure. Background Art

[0002] The roof of a building is the key part of the top of the building. It undertakes multiple functions such as load-bearing, enclosure, waterproofing, thermal insulation and shaping of the building. Its design needs to comprehensively consider factors such as climate, architectural style, functional requirements and budget.

[0003] In northern cities, winters are often extremely cold, with heavy snowfall lasting for long periods of time. The thick snow piled up on the roof will not only increase the load-bearing burden of the roof, but also, under the triggering of some external factors, such as a sudden rise in temperature, a sudden increase in wind speed, or an overload of snow, the snow may randomly fall off. If a pedestrian happens to be walking under the building at this time and is hit by the falling snow, there will be a huge safety hazard. Therefore, when the snow on the roof accumulates to a certain thickness, manual snow removal must be carried out. However, the temperature is extremely low in winter, and the flexibility of human limbs is greatly reduced. In addition, factors such as the smooth surface and large slope of the roof make manual snow removal not only difficult and costly, but also accompanied by great safety risks. In view of this, in response to the above-mentioned problems, the present invention came into being. Summary of the Invention

[0004] The purpose of the present invention is to provide a building roof structure, which solves the problem of snow accumulation on the roof by replacing manual labor with machinery, thereby reducing the difficulty of snow clearing, reducing costs and being safer.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a building roof structure, comprising a building main body and an inclined roof formed on the building main body, the outer surface of the inclined roof is provided with a counterweight snow-clearing member extending in a horizontal direction, the outer surface of the inclined roof is provided with a sliding component connected to the counterweight snow-clearing member and allowing the counterweight snow-clearing member to move up and down along the outer surface of the inclined roof, and the counterweight snow-clearing member is connected to a drive component for driving the counterweight snow-clearing member to move.

[0006] By adopting the above technical solution, when snow needs to be cleared from a sloping roof, the driving assembly and the sliding assembly drive the weighted snow-clearing element to move up and down along the outer surface of the sloping roof, thereby shifting the snow accumulated on the outer surface of the sloping roof, causing the snow to fall automatically under the force, thus completing the snow-clearing operation. This structure solves the problem of snow accumulation on the roof by replacing manual labor with machinery, thereby reducing the difficulty of snow clearing, reducing costs, and improving safety.

[0007] The specific steps for clearing snow with the structure of this application are as follows: the initial position of the counterweight snow clearing unit is set at the highest point of the sloping roof. When snow accumulates on the sloping roof, the limiting force acting on the counterweight snow clearing unit is released by the driving assembly, so that the counterweight snow clearing unit pushes the snow downward under the action of gravity, thereby completing the one-time and thorough snow clearing operation, and can well ensure the cleaning quality and avoid cleaning omissions. The heavier counterweight snow clearing unit can well overcome the cleaning resistance caused by clearing snow and can reduce the large load on the driving assembly, thereby improving cleaning efficiency and reducing equipment investment costs.

[0008] It is further configured that: the counterweight snow clearing piece has a weight-increasing state and a weight-reducing state, and the counterweight snow clearing piece is connected to a control component for controlling the counterweight snow clearing piece to switch between the weight-increasing state and the weight-reducing state.

[0009] By adopting the above technical solution, when snow needs to be cleared, the control member switches the counterweight snow clearing unit to a weighted state, allowing the counterweight snow clearing unit to effectively overcome the resistance encountered during cleaning, ensuring cleaning quality while making the arrangement more reliable. When snow does not need to be cleared, the control member switches the counterweight snow clearing unit to a weighted state, reducing the force on the drive assembly and the load-bearing burden on the roof, so that the drive assembly and the roof will not be in an overloaded state for a long time, thereby extending the service life of the drive assembly and the building structure.

[0010] It is further configured as follows: a counterweight cavity with an opening facing upward is formed on the counterweight snow-clearing piece, the counterweight cavity extends along the length direction of the counterweight snow-clearing piece to form a long strip, and the counterweight snow-clearing piece is provided with a drainage port connected to the counterweight cavity.

[0011] By adopting the above technical solution, the weighted snow-clearing component can be controlled to switch between a weighted state and a weighted state by controlling the ratio of water injected into or discharged from the weighted cavity.

[0012] It is further configured as follows: the control component includes a water injection component for injecting water into the counterweight chamber and a sealing component that cooperates with the counterweight snow-clearing component and is used to seal the drain outlet. The sealing component is located on one side of the movement path of the counterweight snow-clearing component. When the sealing component is in a sealed state, the sliding component gives the counterweight snow-clearing component an upward lifting stroke.

[0013] By adopting the above technical solution, when the sealing member is in a sealed state, water is injected into the counterweight cavity through the water injection assembly, and the water in the counterweight cavity will freeze into ice in the counterweight cavity due to the decrease in ambient temperature. Therefore, during the cleaning process of the counterweight snow-clearing member, even if the sealing member is not in a sealed state, it will not affect the cleaning operation of the counterweight snow-clearing member on the accumulated snow. When the ambient temperature rises, the ice in the counterweight cavity melts, and the counterweight snow-clearing member can be automatically switched from a weight-increasing state to a weight-reducing state. Since the water in the counterweight cavity may stick to the sealing member during the freezing process, the lifting stroke is set to enable the driving assembly to drive the counterweight snow-clearing member to perform an upward pulling motion, thereby solving the sticking phenomenon and ensuring the feasibility of the structure. The time for the water injection assembly to inject water into the counterweight cavity can preferably be before the ambient temperature is high, that is, above zero degrees.

[0014] It is further configured as follows: the water injection assembly is arranged at one end of the movement path of the counterweight snow removal component and is located at the highest point of the inclined roof. The water injection assembly includes a water injection main pipe and several water injection branches connected to the water injection main pipe. The water injection branches are arranged along the length direction of the counterweight snow removal component. When the sealing component is in a sealed state, the injection path of the water outlet of the water injection branch intersects with the opening of the counterweight cavity.

[0015] By adopting the above technical solution, the water injection branch pipe sprays water into the opening of the counterweight cavity, thereby completing the weight increase operation of the counterweight cavity.

[0016] It is further configured as follows: the inclined roof is provided with an insulation component packaged on the outside of the water injection component, the insulation component has an open state and a closed insulation state, the water injection branch pipe has a working state and a non-working state, when the water injection branch pipe switches between the working state and the non-working state, it can drive the insulation component to switch between the open state and the closed insulation state, and the working state of the water injection branch pipe includes a water injection state for injecting water into the counterweight chamber and a spraying state for spraying toward the outer surface of the inclined roof.

[0017] By adopting the above technical solution, the insulation component is used to prevent the water in the water injection component pipe from freezing, thereby ensuring the feasibility and reliability of the design structure. When the water injection branch pipe is not in operation, the insulation component is in a closed insulation state to effectively insulate the water injection component. When the water injection branch pipe is in operation, the insulation component is in an open state, so that the insulation component does not interfere with the normal water injection operation of the water injection component. When snow removal is required in winter, the water injection branch pipe is switched to the water injection state. When cooling the roof in summer, the water injection branch pipe is switched to the spraying state to perform the cooling operation.

[0018] It is further configured as follows: the insulation component includes an insulation box body fixedly arranged on the inclined roof and surrounding the water injection component, and an insulation box cover covering the top of the insulation box body opening.

[0019] By adopting the above technical solution, the thermal insulation box body cooperates with the thermal insulation box cover to realize opening and closing operations.

[0020] It is further configured as follows: the water injection branch pipe includes a fixed section connected to the water injection main pipe and a lifting section that is sealed and slidably arranged above the fixed section; the water outlet is arranged on the side wall of the lifting section and faces the side of the counterweight snow clearing component; the lifting section is located below the insulation box cover and is fixedly connected to the insulation box cover.

[0021] By adopting this technical solution, water flows through the water injection main pipe and enters the fixed section and the lifting section in sequence. The water pressure injected into the lifting section drives the lifting section to move the insulation box cover upward, thereby realizing the coordinated control operation of the insulation assembly. The lifting section's height can be adjusted by controlling the water injection flow rate, thereby changing the height of the water outlet and realizing the switching between the water injection state and the spraying state.

[0022] It is further configured as follows: the sliding assembly is configured as two groups corresponding to the two ends of the counterweight snow removal piece respectively; the sliding assembly includes a slide rail arranged on the inclined roof, a slide groove formed on the slide rail and having a lateral opening, and a slider connected to the counterweight snow removal piece and slidingly arranged in the slide groove; the sealing piece is a rubber sealing block fixedly arranged on the side of the slide rail facing the counterweight snow removal piece.

[0023] By adopting the above technical solution, the slider moves within the chute, guiding the weighted snow removal unit to slide, and the rubber seal provided in conjunction with it seals the drain outlet. A blocking brush can be installed at the opening of the chute to prevent snow from entering the chute and affecting the normal sliding of the weighted snow removal unit.

[0024] It is further configured as follows: the driving assembly includes a winch installed under the inclined roof and a guide hole provided on the inclined roof near its highest position, and the traction rope of the winch passes through the guide hole and is connected to the counterweight snow clearing component.

[0025] By adopting the above technical solution, the winch pulls the counterweight snow-clearing piece, and then drives the counterweight snow-clearing piece to rise and fall.

[0026] In summary, the present invention has the following beneficial effects: the present invention solves the problem of snow accumulation on the roof by replacing manual labor with machinery, thereby reducing the difficulty of snow clearing, reducing costs and being safer.
