Description
Technical Field
The utility model relates to a snow accumulation and sliding and impact preventing device on an arched roof.
Background
With the increasing national environmental protection requirements, a large number of large-area open storage yards need to be closed, and in the structure type selection process, the arch-shaped building is reasonable in stress and large in applicable span due to the specific arch shape, and is selected by more engineers. Arch-shaped buildings are more and more common in our production and life.
In northern areas of China, people often encounter more snowing weather in winter, and due to the arc-shaped appearance of the arch-shaped building, a gutter is rarely arranged in the conventional design, and more snow can freely slide to the ground. When the roof is very high, the building volume is very large, and the two sides of the roof are not provided with buffer zones for snow to slide down freely, the snow in large amount can slide down in combination with ice blocks to generate huge impact on the adjacent ground and the building. When a road and people pass by the adjacent road, the skiing impact can generate greater threat to the personal safety of the people; when adjacent to other buildings, the skiing impact will cause serious damage to the skins of the other buildings.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model provides a snow accumulation and sliding impact preventing device arranged on an arched roof, which can effectively reduce the sliding speed of accumulated snow on the arched roof, disperse large snow blocks and effectively weaken the impact of the sliding of the accumulated snow on the ground and buildings adjacent to the roof.
In order to achieve the purpose, the snow fall and impact preventing device on the arched roof is characterized in that a plurality of supporting arms protruding out of the outline of the arched roof are arranged at intervals at a preset height of the arched roof, and a grid is arranged between every two adjacent supporting arms.
Furthermore, the arched roof is a steel structure roof; the steel structure roof comprises a roof main structure and a roof panel arranged on the outer surface of the roof main structure; a plurality of small upright posts are arranged at the preset height of the roof main structure at intervals; one end of the small upright post is connected with the main structure of the roof, and the other end of the small upright post penetrates through the roof panel for a preset distance to form a supporting arm.
Furthermore, the supporting arm is perpendicular to the roof.
Furthermore, the grid is a section steel grid.
Preferably, the setting height of the small upright post can be determined according to the use requirement, and the ideal setting height is that the included angle between the roof and the horizontal plane is 50-70 degrees.
Preferably, the small upright posts are distributed densely as much as possible so that the impact load of the accumulated snow is uniformly transmitted to the main structure. When the small upright column is loaded greatly, a supporting rod can be additionally arranged at the upper part or the lower part to form a tripod so as to increase the strength.
Preferably, the section steel grid can be provided with only the longitudinal main steel ribs to form the gaps among the steel ribs into strips, or can be additionally provided with the secondary steel ribs among the longitudinal main steel ribs to form the gaps among the grids into nets.
In order to achieve the purpose, the method for preventing the accumulated snow from sliding and impacting on the arched roof comprises the step of arranging snow breaking grids at preset heights of the arched roof at intervals.
Further, the snow breaking grid comprises: a plurality of supporting arms protruding the outline of the arched roof are arranged at the preset height of the arched roof at intervals, and a grid is arranged between every two adjacent supporting arms.
Furthermore, the arched roof is a steel structure roof; the steel structure roof comprises a roof main structure and a roof panel arranged on the outer surface of the roof main structure; a plurality of small upright posts are arranged at the preset height of the roof main structure at intervals; one end of the small upright post is connected with the main structure of the roof, and the other end of the small upright post penetrates through the roof board for a preset distance to form a supporting arm.
According to the utility model, the snow accumulation and sliding impact preventing device is arranged on the roof earlier, so that the sliding speed of snow on the arched roof is reduced, large snow blocks are dispersed, snow is broken, and the impact of the sliding of the snow on the ground and buildings adjacent to the roof is effectively weakened.

Detailed Description
The utility model is further described with reference to the following figures and detailed description.
The arched roof of the present invention may be a concrete roof or a steel roof, and for convenience of explanation, the steel roof will be described below.
Example 1
The small upright posts (3) (figure 1) which are vertical and protrude out of the roof are arranged at a certain height on the main roof structure (1), the small upright posts (3) can be made of square steel pipes, and the small upright posts (3) are arranged along the longitudinal length of the roof along with the main roof structure (1). The distance between the small upright posts (3) can be attached to the main structure, certain rigidity is ensured, and the small upright posts (3) can participate in structural calculation. The bottom of the small upright post (3) is firmly connected with the main roof structure (1), the connection mode can be selected by welding or bolt connection, the top of the small upright post penetrates through the roof panel (2) for a certain distance, the roof panel penetrating position needs to be well waterproof, and the top of the small upright post (3) needs to be provided with a sealing plate to prevent water accumulation (attached figure 3). The length of the small upright post (3) protruding out of the roof needs to be calculated, so that accumulated snow can fall on the small upright post when sliding and throwing away, and snow can be effectively broken. The section steel grid (4) is firmly connected with the part, protruding out of the roof, of the small upright post (3) and attached to the small upright post (3) and arranged along the longitudinal through length of the roof. The section steel grid (4) can be formed by welding section steel. The number of the steel section grids (4) along the longitudinal main steel ribs of the roof can be selected from 2 to 3, gaps need to be reserved among the longitudinal main steel ribs, broken snow can fall along the gaps, snow is not accumulated at the gaps, and the gaps among the longitudinal main steel ribs can be arranged to form a strip (shown in an attached figure 4).
Example 2
