Abstract
The utility model relates to a protection device for a roof with a lightweight steel structure, in particular to an overload protection device for snow load of a roof with a lightweight steel structure, which is a preferred energy-saving and safe device for realizing overload protection for snow load of the roof with the lightweight steel structure. A device panel is arranged inside a device outer frame, one end of the device panel is hinged with one end of the device outer frame, and the other end of the device panel is connected with the other end of the device outer frame by a control valve. The overload device effectively removes overloaded snow load when the snow load of the roof with the lightweight steel structure is overloaded, guarantees that the snow load of the roof with the lightweight steel structure cannot exceed a designed value under any snowfall conditions, and accordingly improves the safety of the lightweight steel structure. Simultaneously, the overload protection device does not depend on electric power, belongs to energy-saving and safe overload removal devices, is simple and reasonable in structure and suitable for houses with lightweight steel structures of various structural forms, and prolongs the service lives of the houses with the lightweight steel structures to a greater extent.
Description
Technical field
The utility model relates to a kind of roofing system with lightweight steel structure protective device, relates in particular to a kind of roofing system with lightweight steel structure snow load overload protection device, and 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 utility model provides a kind of electric power that do not rely on, and guarantees the snow load of effective removal overload part when the roofing snow load overloads, and effectively improves a kind of roofing system with lightweight steel structure snow load overload protection device of lightweight steel construction safety.
The technical scheme of the utility model technical solution problem is to achieve these goals: 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 utility model and advantage thereof and effect are as follows:
The utility model 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 utility model can be arranged a plurality of the utility model devices 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 utility model 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 utility model does not rely on electric power simultaneously, belongs to the overload device that removes of energy-saving safety.In addition, protective device of the present utility model 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 utility model is described in detail as follows:
Fig. 1 is the main TV structure schematic diagram of the utility model roofing system with lightweight steel structure snow load overload protection device;
Fig. 2 is the A-A sectional structure schematic diagram of the utility model Fig. 1.
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 utility model is further elaborated referring to accompanying drawing of the present utility model, but protection domain of the present utility model 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:
When the utility model specifically uses, be according to light steel structure house roofing form and snow load design load, by calculating the arrangement of determining the utility model protective device and the distance between the utility model protective device.For the situation of local accumulation, should under the prerequisite that does not influence the house function of use, arrange the utility model device in the position at the snow load bulk deposition.And for the equally distributed situation of roofing snow load; the layout of the utility model protective device 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 utility model 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.
