Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Example 1:

as shown in fig. 1, in this embodiment, an outer-inserted portable frontier defense structure for high-altitude plank road includes a fence 1, a plurality of guys 2 arranged on the top of the fence 1, and a plurality of lock catch structures 3 arranged on the bottom of the fence 1 and capable of being connected with grid plates 5, wherein the lock catch structures are hinged to the fence 1, the free ends of the guys 2 are hinged to the lock catch structures 3, and the length of the guys 2 is greater than the height of the fence 1.

As shown in fig. 2, the enclosure 1 is attached to the grating plate 5 on the steel truss 4 such that the enclosure 1 is positioned on the outside and the stay 2 is positioned on the inside of the enclosure 1. Make enclose and keep off the cross node connection on hasp structure 3 and the grid tray 5 on 1, make and enclose and keep off 1 and lean out, be connected hasp structure 3 on the cable 2 and the cross node on the grid tray 5 again, hasp structure 3 on the cable 2 is more leaned on in enclosing hasp structure 3 on keeping off 1 relatively. Because 2 lengths of cable are greater than the height of enclosing fender 1 for cable 2, enclose fender 1 and grid plate 5 can form obtuse triangle structure, under the action of gravity, make to enclose fender 1 and be the trend of turning up and can strain cable 2, thereby play the effect of protection to enclosing the staff that keeps off 1 inside.

Utilize hasp structure 3 to make things convenient for hasp structure 3 and grid plate 5 to install fast to can not cause the destruction to grid plate 5. After the construction of current position was accomplished, can take off cable 2 fast and enclose fender 1 to shift it to next position and construct. This scheme can realize quick installation, demolish, can not lead to the fact destruction to current structure, is favorable to improving the efficiency of construction, and this scheme can reuse many times, can not increase extra construction cost.

Example 2:

on the basis of the above embodiment, in this embodiment, the enclosure 1 includes a rectangular steel bar framework and a steel wire mesh arranged in the steel bar framework. The enclosure 1 is guaranteed to have enough strength to guarantee construction safety, and the whole weight of the enclosure 1 can be controlled to be light, so that the enclosure is convenient to transfer and install.

In this embodiment, the inhaul cable 2 be provided with two, inhaul cable 2 and the tie point that encloses fender 1 set up respectively at two summits that enclose fender 1. Utilize the cable 2 to provide pulling force to enclosing two summits of keeping off 1, be favorable to guaranteeing to enclose the stability of keeping off 1.

The inhaul cable 2 is hinged with the enclosure 1. Thereby facilitating the self-adaptive adjustment of the force bearing point of the inhaul cable 2 so as to make the structure more stable. In this embodiment, the cable 2 is an iron chain. Under the prerequisite of assurance intensity for cable 2 possesses certain flexibility, thereby is convenient for make the hasp structure 3 on the cable 2 find suitable tie point and grid tray 5 to be connected.

In this embodiment, the guy cable 2, the enclosure 1 and the grid plate 5 form an obtuse triangle structure, so that the acute angle between the enclosure 1 and the grid plate 5 is 60-80 degrees, the enclosure 1 tends to rotate downwards under the action of gravity, and the horizontal component of gravity is used to balance the reverse horizontal wind load which may be borne, thereby preventing the enclosure 1 from rotating inwards under the action of wind.

Under the construction of the environment with larger wind power, the outer side of the enclosure 1 can be provided with a balancing weight, the weight of the whole enclosure 1 is increased by the balancing weight, and the component force in the horizontal direction is increased, so that the wind resistance is improved.

Example 3:

as shown in fig. 3, on the basis of the above embodiments, in the present embodiment, the locking structure 3 includes a C-shaped lock. The crotch that utilizes C type hasp is convenient for catch on the cross node of grid board 5 to guarantee to enclose the stability that keeps off 1, under the effect of enclosing the pull force that keeps off 1, can prevent that hasp structure 3 from breaking away from. In this embodiment, the opening of the C-shaped lock catch faces outward, so as to prevent the C-shaped lock catch from being loosened and loosened accidentally.

As shown in fig. 4, the opening of the C-shaped lock catch can be provided with a spring fastener for opening or closing the opening, and the spring fastener can further improve the connection strength and stability of the C-shaped lock catch and the grid plate 5, so that the C-shaped lock catch is prevented from being accidentally loosened.

In this embodiment, other undescribed contents are the same as those in the above embodiment, and thus are not described again.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are included in the scope of the present invention.
