Be badly in need of that a kind of installation operation is easy, supporting force is big, can preferably control box beam it is linear, safe and reliable support supporting unload
Knockout case.
Utility model content
In order to simplify the installing/dismounting work for dropping sandbox, preferably control decentering of scaffold speed, preferably controls base plate
Elevation and flatness, make Cast-in-situ Beam linear and the gradient is more accurate, the utility model using jack operation principle there is provided
A kind of Bailey beam support supporting drops sandbox, including base and core cylinder, and the base includes base plate and the first helix tube, the first spiral shell
Coil is provided with fine sand layer on base plate in first helix tube, the first helix tube bottom opening, the core cylinder includes
Top board and the second helix tube, the second helix tube are provided with concrete layer on top board in second helix tube, the core cylinder is set
In on the base, second steel plate keeps level, and the second helix tube of the core cylinder is put into the first spiral of the base
Guan Zhong, the fine sand layer is contacted with the concrete layer.Base and tube filler are applied in combination, support supporting is formed and drops system.
Support supporting is carried out using the sandbox and drops construction, is easy to dismount, is avoided influence of the cast-in-situ box girder horizontal component to support, carries
The high stability and supporting structure security of cast-in-place support.
Further, the height of first helix tube and the second helix tube is 30cm, and the first helix tube is a diameter of
529mm, a diameter of 426cm of the second helix tube.
Further, the top board and base plate are 800 × 800 × 15mm steel plate., can according to the elevation that measurement is given
The elevation of top surface of each sandbox is more effectively controlled, so as to ensure the linear smooth degree of bottom die of box-beam, is pouring box beam
Into the aesthetics of expected design can be reached.
Further, the leakage sand hole is uniformly arranged 4, is respectively positioned on the diagonal of base plate, and then, when falling frame,
Fine sand in same row's upright post base flows out sandbox base by sand losing opening, the Bailey beam on sandbox top uniformly, is integrally fallen, from
And reach the purpose of frame.
The beneficial effects of the utility model are as follows：
1st, supporting drops the installing/dismounting work that sandbox simplifies decentering of scaffold system, and during dropping, can
Decentering of scaffold speed more effectively is controlled, preferably control floor elevation and flatness, make Cast-in-situ Beam line style and the gradient more
Precisely, the security of decentering of scaffold construction is greatly improved.Compared to bowl fastener holder jacking and sulphur-bonded mortar temporary support system
Make simple, installation operation is easy, supporting force is big, can preferably control the linear of box beam, it is to avoid cast-in-situ box girder horizontal component
Influence to support, is a kind of safe and reliable support supporting lowering device.
2nd, according to the given elevation of measurement, the elevation of top surface of each sandbox can be more effectively controlled, so that guard box
The linear smooth degree of beam bottom board, make box beam pour complete can reach the aesthetics of expected design.
3rd, by using unnecessary construction fragment data, construction cost has been saved to a certain extent.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of Section A-A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the present embodiment is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only the example to a part of example of the utility model, rather than whole.Base
Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained under the premise of creative work is not paid
There is other embodiment, belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of Bailey beam support supporting of the present embodiment drops sandbox, including base and core cylinder, described
Base includes the helix tube 3 of base plate 4 and first, and the first helix tube 3 is provided with fine sand layer on base plate 4 in first helix tube 3
7, the bottom open-drain sand hole 5 of the first helix tube 3, the leakage sand hole is uniformly arranged 4, on the diagonal of base plate,
The core cylinder includes the helix tube 2 of top board 1 and second, and the second helix tube 2 is on top board 1, provided with mixed in second helix tube 2
Solidifying soil layer 6, the core cylinder is on the base, and the top board 1 keeps level, and the second helix tube 2 of the core cylinder is put into institute
In the first helix tube 3 for stating base, the fine sand layer 6 is contacted with the concrete layer 7.
As further preferred, the height of the helix tube 2 of the first helix tube 3 and second is 30cm, and the first helix tube is straight
Footpath is 529mm, a diameter of 426cm of the second helix tube.The top board and base plate can be 800 × 800 × 15mm steel plates.
The first helix tube and 800 × 800 × 15mm steel plates sealing in base are tight, and the first spiral bottom of the tube opens 30 ×
20mm sand losing openings, the built-in evengranular fine sand of base.Sand used must sieve, and remove excessive particle, and sand is entering
It must dry or dry before case.
The second helix tube and 800 × 800 × 15mm steel plates sealing in tube filler is tight, and it is unnecessary to pour cushion cap pier shaft
