Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of supporting construction of building foundation pit diagonal brace 1, including retaining-plate 1, retaining-plate 23 and tiltedly
Support 1, in building foundation pit, retaining-plate 1 is connected to the side wall metope of foundation ditch, and a part for the lower end of retaining-plate 1 is embedded in
In the soil of bottom of foundation ditch, the bottom surface of 23 foundation ditches being arranged on of retaining-plate is connected to the ground of foundation ditch bottom surface, retaining-plate 1
Both are connected with each other and are mutually perpendicular to retaining-plate 23, and then between retaining-plate 1 and retaining-plate 23, diagonal brace 1 inclines diagonal brace 1
Bearing diagonal is on retaining-plate 1 and retaining-plate 23, and the upper end of diagonal brace 1 is connected to retaining-plate 1, and lower end is then connected to retaining-plate
23, diagonal brace 1 is overall to include support bar 4, connected unit 6 and hinged seat 1, and support bar 4 is inclined to set, the upper end of support bar 4
Connected unit 6 is connected to, the lower end of support bar 4 is then hinged on hinged seat 1 by latch 7, and the lower end of support bar 4 is hinged on be hinged
It is in the groove on hinged seat 1 when on seat 1, then support bar 4 can be rotated around the hinged place of lower end, supporting
Anchor bar 8 is all preset with plate 1 and retaining-plate 23, connected unit 6 and hinged seat 1 are all worn by anchor bar 8 to be penetrated, even
Connect platform 6 and the cunning penetrated and can not carried out by the limitation of anchor bar 8 on retaining-plate 1 on vertical plane is worn described in anchor bar 8
Dynamic, then the shearing force being subject to for connected unit 6 has support, and hinged seat 1 is worn by anchor bar 8 and penetrated by anchor bar 8
Restriction effect can not be then overall for branch by both cooperation diagonal braces 1 in the slip in the enterprising water-filling plane of retaining-plate 23
Backplate 1 and retaining-plate 23 can not be moved when providing support, and diagonal brace 1 is dismantled if necessary, only need to be by hinged seat
Latch 7 on one 5 takes out and then takes out support bar 4 and company along bold move of the anchoring on retaining-plate 1 perpendicular to retaining-plate 1
Platform 6 is connect, hinged seat 1 is then extracted out from the anchor bar 8 on retaining-plate 23 again, so just by the integral demounting of diagonal brace 1
Get off, diagonal brace 1 is overall not to have damage to be reused, quick-fried when such a dismounting mode need not dismantle armored concrete
Tear is managed, so safety and environmental protection will not pollute to the environment of surrounding.
The overall strip in convex of hinged seat 1, and hinged seat 1 is axially perpendicular to retaining-plate 1, hinged seat 1
The upper surface of upper end bossing is provided with hinged groove 9, and the front and rear of hinged groove 9 runs through hinged seat 1, the position of the lower end of support bar 4
In in hinged groove 9, latch 7 also is located in hinged groove 9 and extends transversely through hinged seat 1 and support bar 4, then the lower end of support bar 4
It is fixed in hinged groove 9, the lower end of support bar 4 and latch 7 are be hinged, and support bar 4 can surround pin joint and carry out when needed
Rotate, be arranged such when being supported in different foundation ditches to different retaining-plates, support bar 4 and hinged seat one can be adjusted
5 relative angle, i.e., and connection retaining-plate 23 angle so that it is retaining-plate that support bar 4, which is in a suitable angle,
Support is provided, the supporting role of maximum can be played.
In addition, steel holding holes array is placed with the left and right both wings side plate of hinged seat 1 itself is used for interspersed anchor
Reinforcing bar 8, anchor bar 8, which is interspersed in reinforcing bar hole array, is relatively fixed retaining-plate 23 and hinged seat 1, is supported in diagonal brace 1
When on retaining-plate 1 and retaining-plate 23, the shearing force being horizontally oriented that hinged seat 1 is subject to, anchor bar 8 is interspersed in
The movement of hinged seat 1 is limited when in reinforcing bar hole array, hinged seat 1 is up moved, so anchor bar 8
Serve resistant function to the shearing force suffered by hinged seat 1, be just so diagonal brace 1 to retaining-plate 1 and retaining-plate 23
Support provides supporting force.
Connected unit 6 is in then circular platform type, and 6 larger one side of connected unit is connected to retaining-plate 1, and smaller one side is provided with hinged seat two
10, the upper end of support bar 4 is hinged on hinged seat 2 10, and connected unit 6 is arranged into circular platform type and larger one side is connected to supporting
Plate 1, the contact area of diagonal brace 1 and retaining-plate 1 is increased, reduces power suffered in lifting surface area increase unit area,
So that diagonal brace 1, which can be retaining-plate 1, provides more effectively support, hinged seat 2 10 is set in the smaller one side of connected unit 6
The upper end of hinged support bar 4, then when being dismantled to support bar 4 and connected unit 6, if anchor bar 8 is crossed, long spacing is too small to be made
Support bar 4 and connected unit 6 are restricted when being extracted out along the anchor bar 8 on retaining-plate 1, then can first surround the He of support bar 4
The pin joint rotary supporting rod 4 of hinged seat 2 10, make support bar 4 and connected unit 6 along the length in the extraction direction of anchor bar 8
Shorten and then extract support bar 4 and connected unit 6 out again, therefore be arranged such and be easy to removing and installing for the entirety of diagonal brace 1.
The side wall of connected unit 6 is provided with through hole 11 of the coil axis parallel to the axis of connected unit 6, anchor bar 8 then from
Interting and mistake in through hole 11, for the inlay card of anchor bar 8 in through hole 11, through hole 11 is that anchor bar 8 provides interspersed point,
It will pass through hole 11 and be arranged to a circle, shearing force of the diagonal brace 1 when being supported suffered by connected unit 6 is dispersed to each connection
Support of putting up a resistance on anchor bar 8 is put, so that overall can bear bigger power.
The optimal choice scope of the diameter of anchor bar 8 is 20~25m, and anchor bar Final 8 degree within this range meets need
Ask and too many space will not be taken, the present embodiment is chosen for 20mm, and the intensity that the anchor bar 8 under this diameter provides support meets
It is required that and space-consuming it is minimum, can be set on identical area most anchor bars 8 strengthen providing it is maximum anti-shearing
Power.
The optimum valuing range of the diameter of support bar 4 is 50~80mm, and the relative intensity of support bar 4 within this range is optimal
It can prevent retaining-plate from shifting, the present embodiment value is 65mm, and exhausted big portion is disclosure satisfy that in this diameter lower support bar semi-finals degree
The support strength of point foundation ditch diagonal brace 1, use range are most wide.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
