Description
Technical field
The utility model relates to building site safety device technical field, is specifically related to a kind of safety guide rail.
Background technology
Frame on the safety guide rail that current building site uses and be all adopt welding manner to be connected between frame with protective screening, this mode is not easy to protective screening and frame detaching and assembling, also inconvenient for transport, if protective screening or frame are damaged by corrosion or other reasons simultaneously, also be not easy to change protective screening and frame, be equivalent to whole protective guard and just scrapped.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of novel safety guide rail, protective screening and frame is fixed by fastening bolt, can either by protective guard and frame quick locking, again can quick-detachment, avoid employing welding manner, avoid the damage to protective screening and frame.
The technical solution of the utility model is: comprise rectangle protective screening, be located at frame and the fastening bolt of protective screening surrounding, described protective screening is welded into net structure by many orthogonal Metallic rod, the most position, edge of protective screening surrounding is respectively equipped with two Metallic rod parallel with wire side, the plane orthogonal that described two parallel metal bars are formed in protective screening wire side, and is provided with gap between described two parallel Metallic rod; Described frame comprises crossbeam, main longitudinal grider and secondary longeron, be two square pipe fittings be arranged in parallel, described secondary longeron both ends are connected with beam side wall respectively, beam-end is connected with main longitudinal grider sidewall respectively, described main longitudinal grider and secondary longeron be arranged in parallel, and described crossbeam is all connected by U-shaped brace and fastening bolt with between main longitudinal grider and between crossbeam with secondary longeron; Described protective screening is located in the square region that is made up of crossbeam and secondary longeron, is evenly distributed with multiple by protective screening and crossbeam or the fixing fastening bolt of secondary longeron in the gap between two parallel metal bars at the most edge of described protective screening.
As preferably, be fixed on crossbeam by fastening bolt bottom the U-shaped brace between described crossbeam and secondary longeron, side arm stretches into secondary rail inner, is fixed by fastening bolt and secondary longeron; Be fixed on main longitudinal grider by fastening bolt bottom U-shaped brace between described crossbeam and main longitudinal grider, beam-end stretches between the two side arms of U-shaped brace, and U-shaped brace and crossbeam are fixed by fastening bolt.
The beneficial effects of the utility model are: the connecting portion between the connecting portion between protective screening and frame and frame crossbeam, main longitudinal grider, secondary longeron is all with bolts, replace original connected mode adopting welding, fast protective screening can either be connected with frame, can remove by fast dismantling again, be convenient to on-the-spot installation and transport, be also convenient to keep in repair the protective guard of local damage simultaneously.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the partial schematic diagram of a kind of embodiment of the present utility model.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the present embodiment comprises rectangle protective screening 4, is located at frame and the fastening bolt 7 of protective screening 4 surrounding, protective screening 4 is welded into net structure by many orthogonal Metallic rod, the most position, edge of protective screening surrounding is respectively equipped with two Metallic rod 6 parallel with wire side, the plane orthogonal that two parallel metal bars 6 are formed in protective screening wire side, and is provided with gap between two parallel Metallic rod; Frame comprises crossbeam 3, main longitudinal grider 2 and secondary longeron 1, be two square pipe fittings be arranged in parallel, secondary longeron 1 both ends are connected with crossbeam 3 sidewall respectively, crossbeam 3 end is connected with main longitudinal grider 2 sidewall respectively, main longitudinal grider 2 and secondary longeron 1 be arranged in parallel, are all connected by U-shaped brace 5 and fastening bolt 7 between crossbeam 3 with main longitudinal grider 2 and between crossbeam 3 with secondary longeron 1; Protective screening 4 is located in the square region that is made up of crossbeam 3 and secondary longeron 1, is evenly distributed with multiple by protective screening 4 and crossbeam 3 or the fixing fastening bolt 7 of secondary longeron 1 in the gap between two parallel metal bars 6 at the most edge of protective screening 4.
In the present embodiment, be fixed on crossbeam 3 bottom the U-shaped brace 5 between crossbeam 3 and secondary longeron 1 by fastening bolt, it is inner that side arm stretches into secondary longeron 1, fixed by fastening bolt 7 and secondary longeron 1; Be fixed on main longitudinal grider 2 by fastening bolt bottom U-shaped brace 5 between crossbeam 3 and main longitudinal grider 2, crossbeam 3 end is stretched between the two side arms of U-shaped brace 5, and U-shaped brace 5 and crossbeam 3 are fixed by fastening bolt.
In above-described embodiment, protective screening is fixed by fastening bolt and frame, the mode that the crossbeam of frame also adopts U-shaped brace to match with fastening bolt with the connection between main longitudinal grider, secondary longeron, avoid and adopt welding manner to be connected with between main longitudinal grider, secondary longeron with frame and crossbeam by protective screening, because this reducing the equipment using welding procedure relevant, only need to use spanner or screwdriver just protective guard can be mounted and dismounted, be also convenient to the transport of protective guard, increase work efficiency.
Arrange two at protective screening edge to be parallel to each other and the Metallic rod having certain intervals, the therefore installation site of fastening bolt not circumscribed, can position according to actual loading situation, make in-site installation convenient simultaneously.
