Description
Technical field
This utility model relates to a kind of cast-in-place open caisson formwork system, particularly relates to a kind of cast-in-place open caisson one side cantilever formwork system.
Technical background
Open caisson application in Practical Project gets more and more, but, owing to open caisson construction is affected by the complexity etc. of the multiformity construction management of the uncertain construction environment of geological state so that the construction of open caisson has the feature of uncertainty.Meanwhile, mould in caisson wall, during due to concrete construction, affected by the lateral pressure of concrete, so beating tightr and tightr, will not produce burst apart, be not easy to produce spillage.But the necessary firm supporting of the interior mould of open caisson, to prevent bigger deformation.
Traditional open caisson formwork uses steel pipe to set up the framed bent support system as template, and this technique uses steel pipe quantity big, and the cycle of setting up is long, and the defects such as Form floating, swollen mould, concrete walls surface evenness, perpendicularity difference easily occurs, and construction quality is difficult to ensure that.Open caisson inner side template installs needs to set up from top to down scaffold, due to the excavation of the internal soil body of open caisson, need that repeats to set up and remove scaffold, and along with the excavation of the soil body in well, underground construction is more complicated, sets up scaffold for sunk well without bailing construction inside more difficult；Open caisson outboard template is also required to repeat assembling and disassembling, and efficiency of construction is low.
In consideration of it, need a kind of Stability Analysis of Structures of invention at present badly, be prone to dismounting, easy to operate, the moving horizontally of unilateral cantilever formwork and well exterior sheathing in well can be realized, it is suitable for differing heights open caisson formwork system.
Summary of the invention
The purpose of this utility model is to provide a kind of Stability Analysis of Structures, is prone to dismounting, easy to operate, the moving horizontally of unilateral cantilever formwork and well exterior sheathing in can realizing well, is suitable for differing heights open caisson formwork system.
For achieving the above object, this utility model have employed techniques below scheme:
Cast-in-place open caisson formwork system, it is characterised in that: include steel pipe through walls, steel pipe diagonal brace, built-in fitting, movable bar, inner side template, outboard template, screw rod, bearing diagonal, horizontal support and double-pole scaffold；Steel pipe through walls passes the borehole wall, and one end is fixed on double-pole scaffold by fastener, and other end bottom arranges steel pipe diagonal brace, is fixed on inside the borehole wall by built-in fitting bottom steel pipe diagonal brace；Inner side template is connected drawing by screw rod with outboard template, and inner side template arranges bearing diagonal, and bearing diagonal one end is fixed in borehole wall inner side template, and the other end is fixed on steel pipe through walls；Borehole wall outboard template arranges horizontal support, and horizontal support one end is fixed on borehole wall outboard template, and the other end is fixed on movable bar.
Further, the borehole wall is embedded with pvc pipe.
Double-pole scaffold cross bar one end is groove structure, and movable bar is arranged in groove and is bolted, and after removing bolt, movable bar can move in groove.
This utility model has following feature and a beneficial effect:
(1) after first segment open caisson construction, without again dismounting, only need to remove Screw arbor with nut at both-ends, outboard template can move horizontally laterally and be fixed on double-pole scaffold, treating that well sinking postpones to specific bit and be fixed formwork again, construction period substantially shortens.
(2) inner side template of open caisson is supported on steel pipe through walls, is formed and supports and set up platform, and steel pipe bottom through walls arranges diagonal brace, it is ensured that decrease scaffold building quantity while Stability Analysis of Structures.
(3) carry out skewed horizontal load during cast-in-place open caisson formwork, only set up scaffold in double-pole scaffold coordinates than conventional construction method in open caisson lateral wall and carry out formwork or add level land diagonal brace, there is higher stable and property safety.

Detailed description of the invention
Just being not repeated in these enforcements such as present embodiment welding for steel structure technique, bolt connection construction technique, template-setup technique and concrete pouring construction technique, emphasis illustrates that this utility model relates to the embodiment of structure.
Fig. 1 is this utility model cast-in-place open caisson formwork system first segment open caisson formwork erecting structure schematic diagram.With reference to shown in Fig. 1, this utility model cast-in-place open caisson formwork system specifically includes that steel pipe 1 through walls, steel pipe diagonal brace 2, built-in fitting 3, movable bar 5, inner side template 7, outboard template 8, screw rod 11, bearing diagonal 14, horizontal support 16 and double-pole scaffold 17.
With reference to shown in Fig. 1, interspersed steel pipe 1 through walls in borehole wall reserving hole, steel pipe 1 one end through walls is fixed on double-pole scaffold 17 by fastener 4, and steel pipe 1 bottom through walls arranges steel pipe diagonal brace 2, steel pipe diagonal brace 2 one end is connected with steel pipe 1 through walls, and the other end is fixed on inside the borehole wall by built-in fitting 3；In place for the most assembled good borehole wall inner side template 7 opsition dependent, then install bearing diagonal 14, install Screw arbor with nut at both-ends 11, with galvanized wire by taper bolt 13 colligation on framework of steel reinforcement；Borehole wall inner side template 7 passes through screw rod 11 to being pulled together with outboard template 8.Borehole wall inner side template 7 arranges bearing diagonal 14, and bearing diagonal 14 one end is fixed on inner side template 7, and the other end is supported on steel pipe 1 through walls.
With reference to shown in Fig. 2, double-pole scaffold cross bar 23 one end is groove structure, fixes in movable bar 5 is arranged on groove 24 and by bolt 6, and after removing bolt 6, movable bar 5 can move in recessed 24.
