Abstract
The utility model discloses a lift type protective railing comprising a steel wire gauze and an outer frame, wherein the steel wire gauze is arranged in the outer frame and comprises upper and lower parts; the upper-part steel wire gauze and the lower-part steel wire gauze are connected through hinges; the outer frame comprises a top frame an two side frames; the two side frames are respectively formed by sleeving an upper-part casing pipe in a lower-part casing pipe; the upper-part casing pipes and the lower-part casing pipes are fixed through plug pins; and the upper-part steel wire gauze and the top frame are detachably and fixedly connected. In the top-down construction, the lift type protective railing provided by the utility model is arranged at a position in which the earth borrowing layer is, so that the requirements of the rotation operation of digging machines or grab buckets in the earth cutting stage are satisfied and the protection requirements of opening edges in the structural construction stage are satisfied.
Description
Technical field
The utility model belongs to building underground construction technical field, relates to a kind of guard rail, and is particularly a kind of for the fetch earth ascending/decending guard rail on mouthful limit of the contrary sequence method first floor.
Background technology
In the reverse construction, digging machine or grab bucket are all fetched earth at the first floor, about digging machine or the liftoff 0.9m of grab bucket operating room, radius of gyration is larger, adopting fixed railing to be hit when rotated by digging machine touches off, and cut the earth and carry out stage by stage, when cutting the earth end, begins structure construction in a stage, the limit is faced at the hole during structure construction must guard rail, the place, limit is faced at the conventional construction hole must install the guard rail that is not less than 1.2m, in the soil excavation process, because of the requirement of excavator rotary work, fixed protective guard of shoveling stage needs to remove, the at once recovery of formula protective guard that is standing of cutting the earth, the repetitive operation amount is large in the work progress, precarious position swiftly occurs easily.
The utility model content
Technical problem to be solved in the utility model is that existing fixed guard rail is improved, a kind of ascending/decending guard rail is provided, make it satisfy simultaneously mouthful requirement of facing the limit isolating and protecting of fetching earth of excavation and construction stage and structure construction stage, the defects that exists to overcome prior art.
The technical scheme of the utility model technical solution problem is as follows:
A kind of ascending/decending guard rail, comprise gauze wire cloth and outer rim, described gauze wire cloth is arranged in the outer rim, it is characterized in that described gauze wire cloth comprises up and down two parts, upper steel silk screen and bottom gauze wire cloth are connected through the hinge, described outer rim comprises top frame and two side frames, two side frames are set in the lower parts casing pipe by upper sleeve respectively and consist of, and fix by latch between upper sleeve and the lower parts casing pipe, and described upper steel silk screen is fixedly connected with the top frame is detachable.
By above disclosed technical scheme as can be known, the utility model beneficial effect is as follows: when excavation and construction soil, only need latch is extracted and the connection disassembling of top frame and gauze wire cloth junction can be finished lifting, adjustable height descends from original height, satisfied the requirement of cut the earth stage digging machine or grab bucket rotary manipulation, and excavation and construction is finished when changing structure construction over to railing is recovered to rise to original calibrated altitude, thereby satisfies the requirement of shelter that the limit is faced at structure construction stage hole.The utility model integral arrangement is exquisite, convenient, the easy accessibility of installation, be difficult for being damaged by digging machine, but Reusability.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, 2, the utility model ascending/decending guard rail, comprise gauze wire cloth and outer rim, described gauze wire cloth is arranged in the outer rim, described gauze wire cloth comprises up and down two parts, upper steel silk screen 1 is connected by hinge 3 with bottom gauze wire cloth 2, described outer rim comprises top frame 4, lower frame 5 and two side frames 6, two side frames are set in by upper sleeve 601 respectively that lower parts casing pipe 602 is interior to be consisted of, fixing by latch 7 between upper sleeve 601 and the lower parts casing pipe 602, described upper steel silk screen 1 and top frame 4 detachable being fixedly connected with.Upper steel silk screen and upper side frame are fixed by bolts and nuts.
Described top frame 4 is the steel pipe of a horizontally set.
Described upper steel silk screen 1 and bottom gauze wire cloth 2 are fixedly installed on respectively in the angle frame 8, link to each other with outer rim respectively by angle frame 8.
Specific embodiment: the high 1.2m of ascending/decending guard rail, long 1.8m, lower frame 5 liftoff 200mm, the hole that can satisfy the non-shoveling stage is faced frontier defense and is protected requirement.When considering the digging machine rotation, the top organism bottom is liftoff to be not less than 1m, so in manufacturing process, lower frame 5 top gauze wire cloths are divided into two upper steel silk screen 1 high 500mm, bottom gauze wire cloth 2 high 300mm, fixing with hinge 3 two gauze wire cloth junctions, upper steel silk screen 1 is then fixed with bolts and nuts with steel pipe junction, top, and the both sides frame all adopts the method for " big steel pipe overlaps little steel pipe ", and steel pipe high 650mm in bottom adopts
Steel pipe, steel pipe high 650mm in top adopts
Steel pipe, make respectively latch 7 in the top cross steel pipe inboard of both sides.Height after the turnover of ascending/decending railing is 0.7m, can satisfy the rotary manipulation requirement of shoveling stage digging machine or grab bucket.
The above is preferred embodiments of the present utility model only, is not to limit protection domain of the present utility model, and every equal conversion of doing according to the utility model claim is all within protection domain of the present utility model.
