Abstract
The invention relates to a lightweight steel structure roof protection device, in particular to a lightweight steel structure roof snow load overload protection device, which is an energy-saving and safe first-choice device for lightweight steel structure roof snow load overload protection. A device panel is arranged in an outer frame of the device, one end of the device panel is hinged with one end of the outer frame of the device, and the other end of the device panel is connected with the other end of the outer frame of the device through a control valve. Overloaded snow load can be effectively unloaded when the snow load on a roof of a lightweight steel structure house is overloaded, thereby ensuring that the snow load on the roof of the lightweight steel structure house does not exceed the design value under any snowfall conditions, and further improving the safety of the lightweight steel structure. Simultaneously, the device is independent of electrical power and belongs to the energy-saving and safe overload-removing device; in addition, the device is simple and reasonable in structure and applicable to the lightweight steel structure houses in various structural forms, and the service life of the lightweight steel structure house can be prolonged to the maximum extent.
Description
Technical field
The present invention relates to a kind of roofing system with lightweight steel structure protective device, relate in particular to a kind of roofing system with lightweight steel structure snow load overload protection device, it is energy-conservation, safe roofing system with lightweight steel structure snow load overload protection device.
Background technology
Light steel structure house is to the highstrung a kind of building structure form of snow load, is damaged easily when snowfall is big even collapses, and causes huge property loss.At present, adopt roofing snow melt technology to come removal roofing system with lightweight steel structure snow load usually, this roofing snow melt technology is to utilize special-purpose gutter snow melting, and the employing heating cable is a pyrotoxin, and the ice and snow of roof, gutter and the leader of building is melted.But this roofing snow melt technology needs frequent maintenance on the one hand, and consumed power during use causes the increase of building use cost; On the other hand, might cause supply of electric power to interrupt under the snowstorm weather, can not ensure the validity of snow removing, applying of this roofing snow melt technology is subjected to great restriction for this reason.Therefore, be necessary to develop a kind of electric power, low, simple and practical light steel structure house roofing snow load overload protection device of cost of not relying on, avoid the generation of light steel structure house snow disaster accident.
Summary of the invention
For addressing the above problem, the invention provides a kind of electric power that do not rely on, when the roofing snow load overloads, guarantee the snow load of effective removal overload part, and effectively improve a kind of roofing system with lightweight steel structure snow load overload protection device of lightweight steel construction safety.
The technical scheme of technical solution problem of the present invention to achieve these goals is: a kind of roofing system with lightweight steel structure snow load overload protection device; be provided with the device panel in its device housing; this device panel one end and described device housing one end are hinged, and the other end of this device panel links to each other by control valve with the other end of described device housing.
Described device panel is made up of the frame of dull and stereotyped tempered glass and this flat board tempered glass neighboring.
Described frame is a kind of of metal type frame or plastic-steel formula frame.
Described control valve is made up of with the fixed head that is fixed on the device housing set bolt and the junction plate that is fixed on the frame.
Described junction plate and fixed head are angle steel.
Design principle of the present invention and advantage thereof and effect are as follows:
The present invention is owing to adopt at suitable position, roof purline outside erecting device housing, and device panel one end in the device housing is hinged with the device housing, and device panel one end adopts bolt to be connected as control valve with the fixed head that is fixed on the device housing with junction plate on being fixed on frame.When the roofing snow load overloads, the bolt shear destruction of control valve, the device panel is fallen around the hinge or the rotating shaft of device housing, form a cavity in the snow load removal on the device panel, snow around making in the certain limit slides to the hole, and then on the dismounting device panel and the accumulated snow near certain zone.The present invention can arrange a plurality of apparatus of the present invention according to the arrangement principle and the mode of light steel structure house structure on roof purline, make the snow load of whole roofing obtain removal, and the snow load of roofing is reduced to below the design load.
The snow load of the present invention's effective removal overload when light steel structure house roofing snow load overloads, the snow load that guarantees light steel structure house roofing under any snowfall condition is no more than design load, thereby improve the safety of lightweight steel construction, the present invention does not simultaneously rely on electric power, belongs to the overload device that removes of energy-saving safety.In addition, protective device of the present invention is simple and reasonable, is applicable to the light steel structure house of various form of structure, improves the application life of light steel structure house greatly, has the good social benefit.
Description of drawings
With reference to accompanying drawing, concrete structure of the present invention is described in detail as follows:
Fig. 1 is the main TV structure schematic diagram of roofing system with lightweight steel structure snow load overload protection device of the present invention;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1 of the present invention.
Major part among the figure: device housing 1, device panel 2, frame 3, control valve 4, fixed head 5, junction plate 6.
The specific embodiment
Also in conjunction with specific embodiments the present invention is further elaborated referring to accompanying drawing of the present invention, but protection scope of the present invention is not limited by specific embodiment, is as the criterion with claims.
Embodiment 1:
A kind of roofing system with lightweight steel structure snow load overload protection device as shown in Figure 1 and Figure 2; be fixed in the device housing 1 in the roof purline outside; be set with device panel 2 in this device housing 1, device panel 2 is made up of the metal type frame 3 of dull and stereotyped tempered glass and this flat board tempered glass neighboring.Device panel 2 one ends are hinged by several hinges and described device housing 1 one ends, and the other end of device panel 2 links to each other by control valve 4 with the adapting position of the other end of described device housing 1.Control valve 4 is made up of set bolt and the fixed head 5 that is fixed on the junction plate 6 on the frame 3 and is fixed on device housing 1, and set bolt links together junction plate 6 and fixed head 5, and junction plate 6 and fixed head 5 are angle steel.
Embodiment 2: device panel 2 one ends are hinged by rotating shaft and described device housing 1 one ends, and frame 3 adopts plastic-steel formula frame.All the other repeat no more with embodiment 1.
When the present invention specifically uses, be according to light steel structure house roofing form and snow load design load, by calculating the arrangement of determining protective device of the present invention and the distance between the protective device of the present invention.For the situation of local accumulation, should under the prerequisite that does not influence the house function of use, arrange apparatus of the present invention in the position at the snow load bulk deposition.And for the equally distributed situation of roofing snow load; the layout of protective device of the present invention need determine that the set bolt diameter of control valve need be according to adopting the snow load design load on the light steel structure house roofing of the present invention to determine according to the structural calculation and the analysis of light steel structure house.During installation by K among Fig. 2 to direction be the carrying direction setting of snow load.
