The utility model discloses compare in traditional scaffold braced system, hanging scaffold braced system practices thrift more than 50% in the consumption of NULL, duration of a project, manpower etc. And the well is darker, the bore is big more, and the saving degree is high more, the safe risk greatly reduced of construction, and the improvement efficiency of construction has better economic benefits.
Description
Technical field
The utility model relates to a kind of scaffold, the built-in flying scaffold of especially a kind of large-diameter well.
Background technology
At present, in all kinds of engineering construction, the well lid making of large-diameter well (as pressure well, sewage valve pit, collecting well etc.) is the difficult point in construction process always, its degree of depth is large, bore is large, load is large, the concrete feature adopting cast-in-place structural more, cause traditional well lid to make being adopting from bottom from lower to upper intensive steel pipe scaffold of setting up to support the template of well lid cast-in-situ concrete.The shortcoming of this support system be the material consumption amounts such as steel tube fastener large, take and tear that engineering quantity is large, the duration of a project long, manpower consumption amount is large, security risk is high open, it needs a large amount of human and material resources, financial resources to ensure carrying out smoothly of engineering.
Utility model content
In order to overcome the deficiency that in traditional well lid manufacturing process, steel concrete shuttering bracing frame is set up, the utility model provides a kind of large-diameter well built-in flying scaffold.
The utility model solves the technical scheme that its technical problem adopts: the built-in flying scaffold of large-diameter well, comprises, and is arranged at rigid platfor and a template layer rigid platfor of three levels of 3 ~ 5 meters, below well head; Template layer rigid platfor is arranged on rigid platfor;
Described rigid platfor and the borehole wall are fixed by the one group of pre-buried frame pipe be provided with, and pre-buried frame pipe inserts in the borehole wall by the preformed hole level that the borehole wall is provided with, and its degree of depth inserted in the borehole wall is more than 2/3rds of thickness of shaft wall; Often organizing pre-buried frame pipe in same level is uniformly distributed perpendicular to the borehole wall; Be provided with oblique drawbar between neighbouring two groups pre-buried frame pipes to connect, pre-buried frame pipe and oblique drawbar are connected and fixed by fastener, and the angle of the pre-buried frame pipe of described oblique drawbar and level is 60 ° ~ 80 °; Template layer rigid platfor is with between rigid platfor, be fixedly connected with by standard staging between the rigid platfor of three levels.
The beneficial effects of the utility model are, compared to traditional scaffold support system, flying scaffold support system saves more than 50% in the consumption of material usage, duration of a project, manpower etc., well is darker, bore is larger, saving degree is higher, the security risk of construction reduces greatly, greatly improves efficiency of construction, has good economic benefit.

Component and numbering in figure:
1-rigid platfor; 2-template layer rigid platfor; The pre-buried frame pipe of 3-; 4-oblique drawbar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figures 1 to 3, the built-in flying scaffold of large-diameter well, comprises, and is arranged at rigid platfor 1 and a template layer rigid platfor 2 of three levels of 3 ~ 5 meters, below well head; Template layer rigid platfor 2 is arranged on rigid platfor 1;
Described rigid platfor 1 is fixed by the one group of pre-buried frame pipe 3 be provided with the borehole wall, and pre-buried frame pipe 3 inserts in the borehole wall by the preformed hole level that the borehole wall is provided with, and its degree of depth inserted in the borehole wall is more than 2/3rds of thickness of shaft wall; Often organizing pre-buried frame pipe 3 in same level is uniformly distributed perpendicular to the borehole wall; Be provided with oblique drawbar 4 between neighbouring two groups pre-buried frame pipes 3 to connect, pre-buried frame pipe 3 is connected and fixed by fastener with oblique drawbar 4, and described oblique drawbar 4 is 60 ° ~ 80 ° with the angle of the pre-buried frame pipe 3 of level; Between template layer rigid platfor 2 with rigid platfor 1, be fixedly connected with by standard staging between the rigid platfor 1 of three levels.
Implementation process:
The dynamic and static load that need carry according to flying scaffold before one, setting up and the bearing capacity at single reserved scaffold borehole wall place, calculate large-diameter well borehole wall preformed hole quantity, safety factor gets 2.
Two, the preformed hole of pre-buried frame pipe 3 is arranged under well lid within the scope of 3 ~ 5 meters, is three layers, and also visual manhole cover plate load is determined after calculating, and can increase or reduce; Interlamellar spacing is 1 ~ 1.5 meter.Every layer of preformed hole all at grade, perpendicular to the borehole wall, is uniformly distributed.
Three, the aperture of the preformed hole of the borehole wall is greater than the outer through 2mm of pre-buried frame pipe 3, and the reserved degree of depth is not less than 2/3rds of thickness of shaft wall.
Four, an interspersed pre-buried frame pipe 3 in each preformed hole, pre-buried frame pipe 3 adopts standard staging pipe, length about 1 meter, is convenient to remove and recycling, and pre-buried frame pipe 3 inserts for thickness of shaft wall in the borehole wall 2/3rds, exposes 0.6 meter inside the borehole wall.
Five, undermost rigid platfor 1 is set up with pre-buried frame pipe 3 in the plane for starting point.
A, every layer of reserved steel pipe standard staging and pre-buried frame pipe 3 to be coupled to each other, to form an entirety, form undermost rigid platfor 1.
B, with standard staging pipe, surrounding in well is connected into quadra, as shown in Figure 2.
C, the pre-buried frame pipe 3 of this quadra and the borehole wall of last layer to be connected by oblique drawbar 4 is oblique, the stability of the bar quadra described in increase and vertical bearing capacity.
D, on described quadra, set up transverse direction, vertical levels joint steel pipe, each 1 meter of spacing, as Fig. 1, form the rigidity platform 1 of the second layer.
Six, repeat after above-mentioned steps, complete setting up of third layer rigid platfor 1 and template layer rigid platfor 2.
Seven, after hound is put up, template is laid at scaffold top, carries out that passs is molded makes reinforcing bar and pouring concrete, completes well lid making.
The utility model is compared to traditional scaffold support system, flying scaffold support system saves more than 50% in the consumption of material usage, duration of a project, manpower etc., well is darker, bore is larger, saving degree is higher, construction safety risk reduces greatly, greatly improve efficiency of construction, and realize good economic benefit.
