Abstract
The utility model relates to a structure of falling is prevented in steel shotcrete in SMW worker method stake envelope foundation ditch connects installation wire rope between the tip of steel shotcrete is rather than the hole for hoist of adjacent H shaped steel. The utility model discloses utilize SMW to be good at method H stake shaped steel up -pull and insert the hole for hoist that shaped steel was used, adopt wire rope to bind the steel shotcrete and suspend in midair, ensure that the steel shotcrete changes perhaps equipment collision is followed has wire rope after the support position drops secondary protection at the atress, can guarantee the safety of steel shotcrete.
Description
Technical field
This utility model belongs to excavation field, is related to carry out fall arrest after foundation ditch support system bracing members are installed
Protection, especially bracing members Anti-falling structure in a kind of SMW engineering methods stake building enclosure foundation ditch.
Background technology
During Foundation Pit Construction, shallow excavation of foundation pit adopts the building enclosure of the stake of SMW engineering methods and high-pressure rotary jet grouting pile mostly
Form, foundation ditch support system adopt bracing members, and bracing members are erected on bearing by the built-in fitting in Guan Liang, are not had and Guan Liang
It is reliably connected.Due to the change or the collision of shoveling equipment of bracing members stress in Excavation Process, bracing members presence is fallen
Danger, bracing members fall and have a strong impact on the safety of site operation personnel, while the also safety to foundation ditch.
Utility model content
The purpose of this utility model be overcome current bracing members installation after, there is the danger fallen, there is provided a kind of
Bracing members second protection measure, by using the existing hole for hoist for lifting shaped steel on SMW engineering method stake Shaped Steels, using steel wire rope
Binding suspention is carried out to bracing members, it is ensured that bracing members change in stress or equipment is collided after coming off from support position and has steel wire rope
Second protection, it is ensured that the safety of bracing members.
This utility model solves the technical scheme that adopted of technical problem：
Bracing members Anti-falling structure in a kind of SMW engineering methods stake building enclosure foundation ditch, in the H that the end of bracing members is adjacent
Between the hole for hoist of shaped steel, steel wire rope is installed in connection.
And, described steel wire rope one ends wound is fixed by multiple rope cards in the end of bracing members；The other end bypasses H
The hole for hoist of shaped steel, is fixed by multiple rope cards.
And, the arrangement pitches of described multiple rope cards are 6～8 times of wirerope diameter.
And, multiple rope cards are equidirectional regularly arranged, and the U-loop part of card of restricting is stuck in the one side of fag end, the pressing plate of card of restricting
The one side of main rope is placed on, is tightened by bolt, make steel wire rope be crushed 1/3.
And, fix on the inside of end flanges in bracing members respectively and on the inside of the scalable position of bracing members segmented head, respectively wind a steel
One end of cord.
Advantage of the present utility model and good effect are：
This utility model is entered to bracing members using steel wire rope using the hole for hoist of plug shaped steel on SMW engineering method H pile-type steel
Row binding suspention, it is ensured that bracing members have the secondary guarantor of steel wire rope after stress change or equipment collision come off from support position
Shield, ensure that the safety of bracing members.

Fig. 1 is the connection longitudinal direction schematic diagram of bracing members and H profile steel；
Fig. 2 is the connection floor map of bracing members and H profile steel.
Mounting plane schematic diagrams of the Fig. 3 for bracing members.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are simply retouched
The property stated, be not determinate, it is impossible to limit protection domain of the present utility model with this.
Bracing members Anti-falling structure in a kind of SMW engineering methods stake building enclosure foundation ditch, is adjacent in the end of bracing members 1
Connecting steel wire ropes 2 between the hole for hoist 3 of H profile steel 4.Specific construction step is as follows：
(1) bracing members install the requirement according to design drawing, and the support position welded on the built-in fitting of Guan Liang position is installed,
And apply prestressing force according to design requirement, and it is solid with the Guan Liang top of both sides by prestressing force effect, form homeostatic system.
(2) after the completion of SMW engineering methods pile driving construction, shaped steel top board has a hole for hoist for lifting and pulling out shaped steel, checks
Whether breakage and crackle are had around hole for hoist, if flawless and breakage, connection of the hole for hoist as steel wire rope top
Point, and the length of steel wire rope is determined with this position to the distance of bracing members installation site.
(3) after bracing members installation, the installation of bracing members fall arrest steel wire rope is carried out, according to length and the weight of bracing members
Amount, scene select the steel wire rope of diameter 14mm as the lifting rope of bracing members fall arrest, and side is fixed on the inside of end flanges in bracing members
By card connection of restricting after winding bracing members, opposite side is after the scalable position wrapped inside of segmented head by card connection of restricting.
(4), when on steel wire rope and shaped steel, hole for hoist and bracing members connect, the arrangement pitches between rope card are generally steel wire rope
6～8 times of diameter or so, rope card want an in-line arrangement to arrange, and U-loop part should be stuck in the one side of fag end, and pressing plate is placed on the one of main rope
Face.U bolt is tightened, until steel wire rope is crushed till 1/3 or so.
(5) all bracing members, after fall arrest steel wire rope installation, then bracing members are installed and steel wire rope quality of connection
Checked, it is ensured that whole installation bracing members are installed and fall arrest works.
Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of conceiving without departing from utility model, some deformations and improvement can also be made, these belong to this reality
With new protection domain.
