Description

Technical Field

[0001] The invention relates to the technical field of steel structure buildings, and in particular to a steel structure factory building capable of preventing snow accumulation. Background Art

[0002] Industrial and civil buildings built with steel are called steel structures. Steel structure workshops and steel structure warehouses mainly refer to the main load-bearing components made of steel. They include steel columns, roof beams, steel structure foundations, steel purlins and roof panels. The characteristics of steel structure workshops are: 1. Steel structure buildings are light in weight, high in strength and large in span; 2. Steel structure buildings have a short construction period, which reduces investment costs accordingly; 3. Steel structure buildings have high fire resistance and strong corrosion resistance; 4. Steel structure buildings are easy to move and are pollution-free to recycle.

[0003] At present, steel structure factories and warehouses in the prior art generally have a large span and a small roof slope. Snow is very easy to accumulate on the roof panels. In heavy snow and blizzard weather, the snow quickly accumulates into blocks on the roof panels. The temperature of the bottom layer of the snow drops sharply and freezes into ice that is difficult to remove. A large amount of snow can easily cause deformation of steel components and even directly collapse the factory building, posing a major safety hazard to the factory building. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a steel structure factory building which can prevent snow accumulation.

[0005] The present invention provides a steel structure factory building capable of preventing snow accumulation, comprising a roof panel, a support rod and a snow guard; the support rod is fixedly mounted on the upper end of the roof panel and arranged in a matrix; the snow guard is hingedly mounted on the upper part of the support rod and arranged in parallel along the length direction of the roof ridge, and the rotation axis of the hinged snow guard is parallel to the length direction of the roof ridge;

[0006] An elastic reset member for supporting the snow guard upward is provided under the snow guard, and the elastic reset member drives the snow guard to rotate upward toward one end of the eaves, so that the adjacent snow guards along the ridge to the eaves are connected end to end and closed;

[0007] When the snow guard is rotated upward and closed, it is used to block the roof panel and intercept the snowfall; when the snow guard is rotated downward and opened, the friction of the snow on the snow guard is reduced to drive the snow to slide down;

[0008] A needle bar is fixedly installed on the upper end of the roof board and is located below the snow guard. The installation position and height of the needle bar do not hinder the rotation of the snow guard. The needle bar is used to cut off the accumulated snow sliding down along the snow guard and the roof board.

[0009] Furthermore, a limit piece is installed on the upper side of the support rod facing the ridge, and the limit piece is made of a magnet; when the snow guard is rotated upward and closed, its end facing the eaves overlaps the lower end of the limit piece, and the limit piece is sucked upward against the snow guard at its lower end.

[0010] Furthermore, the elastic return member is a torsion spring installed on the hinge shaft of the snow guard.

[0011] Furthermore, the needle bars are arranged at equal intervals along the length direction of the ridge.

[0012] Furthermore, the roof panel is fixedly mounted on the purlin, the purlin is fixedly mounted on the roof beam, and the mounting position of the support rod on the upper end of the roof panel is opposite to the purlin.

[0013] Furthermore, a top beam is fixedly installed at the top of the roof beam along the length direction of the ridge, a ridge top plate is fixed at the upper end of the top beam, both sides of the ridge top plate are connected to the uppermost snow guard located in the direction from the eaves to the ridge, and the bottom ends of both sides of the ridge top plate extend downward and are connected to the roof plate.

[0014] Furthermore, a side baffle is fixedly installed on the upper end of the roof plate, and the side baffle is used to cover the outer ends of the snow guards located at both ends in the length direction of the ridge.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The steel structure factory building capable of preventing snow accumulation of the present invention uses a snow guard to intercept snowfall. The snow guard will automatically increase its slope when under pressure to reduce the friction resistance of snow blocks, unload the snow blocks, and then use a needle rod to cut off the snow blocks to make the snow slide off the roof, so as to prevent a large amount of snow accumulation from causing safety hazards to the factory building and eliminate the need for manual snow removal.

[0020] Figure 4 for Figure 2 A partial view of the . DETAILED DESCRIPTION

[0021] Please refer to Figure 1-4As shown, the steel structure factory building that can prevent snow accumulation proposed by the present invention includes a roof beam 1, a purlin 2 and a roof board 3. The roof board 3 is fixedly mounted on the purlin 2, and the purlin 2 is fixedly mounted on the roof beam 1. A support rod 4 is fixedly mounted on the upper end of the roof board 3, and the support rods 4 are arranged in a matrix. A snow guard 5 is hingedly mounted on the upper part of the support rod 4. The snow guard 5 and the roof board 3 are both colored steel tiles, and the snow guard 5 is arranged side by side along the length direction of the ridge.

[0022] The purpose of the present invention is to intercept snowfall by setting a layer of snow guard 5 above the roof plate 3, and then unload the snow blocks by automatically tilting the snow guard 5 to make the snow slide off the roof, thereby preventing snow from accumulating on the roof of the factory building and causing an impact.

[0023] Specifically, the hinged rotation axis of the snow guard 5 is parallel to the length direction of the ridge; an elastic reset member for supporting the snow guard 5 upward is provided below the snow guard 5, and the elastic reset member is preferably a torsion spring 8 installed on the hinge axis of the snow guard 5. The elastic reset member can also be a member with the same technical effect, such as a pressure spring installed below the snow guard 5. The elastic reset member drives the snow guard 5 to rotate upward toward one end of the eaves, so that the adjacent snow guards 5 along the ridge to the eaves are connected end to end and closed.

[0024] When the snow guard 5 is rotated upward and closed, it is used to block the roof panel 3 and intercept the snowfall; when the snow guard 5 is rotated downward and opened, the friction force of the snow accumulated on the snow guard 5 is reduced to drive the snow to slide down.

[0025] like Figure 1 As shown, when the snow guard 5 is not under pressure, the upward support force provided by the torsion spring 8 to the snow guard 5 is sufficient to drive the snow guard 5 to close. In the closed state, snow will accumulate on the upper end surface of the snow guard 5 when snow falls. Figure 2 and Figure 4 When a certain amount of snow accumulates, the snow guard 5 is pressed and tilted downward. As the slope of the snow guard 5 increases, the friction of the snow decreases, and the snow blocks slide down from the snow guard 5.

[0026] A needle rod 6 is also fixedly installed on the upper end of the roof panel 3, and the needle rod 6 is located below the snow guard 5. The installation position and height of the needle rod 6 do not hinder the rotation of the snow guard 5. The needle rod 6 is arranged at equal intervals along the length direction of the ridge. The needle rod 6 is used to cut off the accumulated snow sliding down the snow guard 5 and the roof panel 3.

[0027] The snow blocks sliding down from the snow guard 5 will fall into the upper end of the roof panel 3, and the snow guard 5 will be reset. When the snow blocks slide down to the roof panel 3, the snow blocks will hit the needle rod 6. The kinetic energy obtained by the snow blocks sliding down will cause the snow blocks to be cut into small pieces or broken due to inertia, thereby greatly reducing the degree of snow accumulation and reducing the friction of each piece of snow again, so that the snow can slide smoothly along the roof panel 3 toward the eaves.

[0028] The snow-proof steel structure factory building of the present invention can play a better snow-proofing effect in heavy snowfall weather. The snow guard 5 can make snow blocks slide down intermittently, making it difficult for snow to accumulate on the roof of the factory building, thereby reducing safety hazards.

[0029] In order to improve the ability of the snow guard 5 to unload snow blocks, the present embodiment further improves the snow unloading method of the snow guard 5. Specifically, a limiting member 7 is installed on the side of the upper part of the support rod 4 facing the ridge, and the limiting member 7 is made of a magnet; when the snow guard 5 is rotated upward and closed, its end facing the eaves overlaps the lower end of the limiting member 7, and the limiting member 7 is adsorbed upward against the snow guard 5 at its lower end.

[0030] The limiting member 7 made of magnet will provide an upward adsorption force to the snow guard 5. In the closed state, the snow guard 5 will be supported by the elastic reset member and the adsorption force of the limiting member at the same time. When too much snow accumulates, the sum of the snow pressure and its own gravity on the snow guard 5 is greater than the sum of the supporting force and the adsorption force. The end of the snow guard 5 facing the eaves will get rid of the adsorption of the limiting member 7 and rotate downward. Afterwards, since the snow guard 5 is no longer subjected to the adsorption force, the snow guard 5 and the snow blocks will generate a downward acceleration, thereby causing the snow guard 5 to tilt more quickly, so that the snow blocks have greater potential energy to be converted into kinetic energy, driving the snow blocks to slide down faster, thereby improving the effect of unloading the snow blocks.

[0031] Furthermore, the installation position of the support rod 4 at the upper end of the roof panel 3 is opposite to the purlin 2, the support rod 4 is perpendicular to the roof panel 3, and the bottom end of the support rod 4 is preferably connected to the purlin 2 by bolts passing through the roof panel 3, thereby reducing the load-bearing capacity of the roof panel 3 and preventing the roof panel 3 from being compressed and deformed.

[0032] Among them, a top beam 9 is fixedly installed at the top of the roof beam 1 along the length direction of the ridge, and a ridge top plate 10 is fixed on the upper end of the top beam 9. Both sides of the ridge top plate 10 are connected with the uppermost snow guard 5 located in the direction from the eaves to the ridge, and the bottom ends of both sides of the ridge top plate 10 extend downward and connect with the roof plate 3. The ridge top plate 10 is used to shield the upper end of the snow guard 5 closest to the ridge position, and can prevent snowfall from entering under the snow guard 5 from the ridge. Side baffles 11 are fixedly installed on the upper end of the roof plate 3, and the side baffles 11 are used to shield the outer ends of the snow guards 5 located at both ends in the length direction of the ridge. The side baffles 11 can prevent snow from entering under the snow guard 5 from the gable direction. In addition, the ridge top plate 10 and the side baffles 11 can also play a role in wind protection.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
