Description

A kind of groove timbering lift-on/lift-off type bracing members

Technical field

The utility model belongs to pipeline construction field, more particularly, to a kind of groove timbering lift-on/lift-off type bracing members.

Background technology

Municipal pipeline, such as sewage pipe, rain pipe, running water pipe, gas pipeline, when pipeline designs, to ensure Pipeline safety often has larger buried depth, directly excavates without supporting, can bring security risk to construction.Under normal circumstances, Construction, which can be taken, beats the mode of steel sheet pile or slope excavation to solve the problems, such as this, however for there is barrier that can not beat on some Stake, lower part working face are not wide enough can not be when slope, we just need some other solutions to ensure safety open Digging groove.

Invention content

In view of this, the utility model is directed to a kind of groove timbering lift-on/lift-off type bracing members, in order to ensure safety Excavate groove.

In order to achieve the above objectives, the technical solution of the utility model is realized in：

A kind of groove timbering lift-on/lift-off type bracing members, including frame, frame includes two frames, and is crossed on two frames Between stull；Stull is from top to bottom distributed multilayer, wherein top stull and middle part stull both ends are respectively welded with two frames It connects, and bottom stull is detachably fixed with two frames and connect.

Further, two frame welds the symmetrical U-shaped support of a row, opening up, and the bottom of U-shaped support in interior side Portion stull both ends respectively with the U-shaped support grafting of both sides.

Further, two frame outside is welded with the mesh sheet of steel wire, and outer baffle is welded on the outside of mesh sheet.

Further, described two frames include the pillar being oppositely arranged two-by-two, and all lower rod ends are connected with extension Spend the stabilizer blade that direction is stretched out.

Further, the stabilizer blade in posts bottom welding angle steel by forming, wherein the branch at left and right sides of two frames Column, one jiao on the inside of it is welded with square steel；And the pillar in the middle part of two frames, on the inside of two corners at respectively with a side Pipe welds.

Further, the pillar at left and right sides of the frame-supporting column of both sides, is formed with hanging ring at the top of it.

Compared with the existing technology, bracing members described in the utility model have the advantage that：

(1) bracing members of the present invention, can install bottom stull when at first, and Pipe installing when is The of short duration behavior of relative time, pipeline welding is of less demanding to operation height, probably has 1 meter enough, but in subsequent backfill During compacting, since it is desired that using artificial hand steered jerk compacting, the operation height that it requires will reach 1.5 meters More than, it needs to dismantle bottom stull successively, increases working space, convenient for manually carrying out backfill rammed earth；And it is always ensured that steel Supporting groove is played the role of in support to be prevented from caving in, and ensures groove construction job safety.

(2) of the present invention to use mesh sheet and outer baffle double-layer structure, mainly by steel wire stress, and outer baffle is for keeping off Soil, in this way setting mitigate weight, can use thin and light steel plate.

(3) steel support structure of the present invention is flexibly light, is installed convenient for live handling, effectively improves construction efficiency, It accelerates construction progress；Compared with other support patterns, this structural cost is low, good in economic efficiency, and construction noise is small, to soil layer around Disturbance is slight.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

A kind of groove timbering lift-on/lift-off type bracing members, as shown in Figure 1, including frame 1 and outer baffle 2.

Frame 1 is fabricated using square steel, including two frames 11, and the stull 12 being crossed between two frames 11. Two frames 11 are symmetrical arranged, and include the pillar 111 being oppositely arranged two-by-two.

111 lower end of all pillars is connected with the stabilizer blade 3 of elongatedness direction stretching.Stabilizer blade 3 in 111 bottom of pillar by welding Angle steel forms.Wherein it is located at the pillar 111 of two frames, 11 left and right sides, one jiao on the inside of it is welded with square steel.And it is located at The pillar 111 at the middle part of two frame 11, on the inside of two corners at respectively with a square tubes soldering.Positioned at two frames, 11 pillar 111 or so The pillar 111 of both sides, is formed with hanging ring 4 at the top of it.

Two frames 11 outside is welded with the mesh sheet 5 of steel wire, and is welded with as the light of outer baffle 2 in 5 outside of mesh sheet Shape steel plate.Light-duty steel plate is supported by steel fabric sheet 5, to reduce strength demand of the steel plate as outer baffle 2, realizes light weight Change.

Stull 12 is from top to bottom distributed three layers, wherein top stull 121 and 122 both ends of middle part stull respectively with two frames Frame 1 welds, and bottom stull 123 is detachably fixed with two frames 11 and connect.Two frames 11 are symmetrical in inside one row of welding U-shaped support 112, U-shaped support 112 it is opening up, and stull 123 both ends in bottom are inserted into respectively in the U-shaped support 112 of both sides.To When according to construction, required space dismounting or installation bottom stull 123 keep the balance of intensity and working space.

Simple installation process is as follows：First bright open channels, then lifted bracing members in slot with excavator, finally use excavator Force will be depressed in ground.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
