With reference to Fig. 1, count from top to bottom, the shaft wall structure of apparatus of the present invention comprises successively two sections concrete guard walls of building (A section, B section), has enclosed the retaining wall to be built (C section) of template and the rock retaining wall (D section) of hypomere, every section all pre-plugged the poor built-in bolt sleeve of specified altitude assignment 1 is arranged, above-mentioned four sections are contour.
Such as Fig. 1-shown in Figure 6, apparatus of the present invention comprise that Lifting and lowering for scaffold system, template part and appendage form, Fig. 1 wherein is the A-A cross-sectional view among Fig. 2, and Fig. 3 is the front elevation drawing of Fig. 2, and Fig. 4 is fixed bearing and the freely movable bearing structure enlarged drawing at the I place among Fig. 1.
With reference to Fig. 1, Fig. 5, described Lifting and lowering for scaffold system is provided with three groups of legs, every group of leg comprises upper supporting leg 17 and lower supporting leg 18, upper supporting leg 17 is fixed on the concrete guard wall (A section) that has been shaped, lower supporting leg 18 is fixed on the rock retaining wall (D section), and upper supporting leg 17 all is fixedly connected with built-in bolt sleeve 1 by high-strength bolt with lower supporting leg 18; Be fixedly connected with a climbing frame 3 between every group of upper supporting leg 17 and the lower supporting leg 18, the hypomere of every climbing frame 3 is provided with a pole-climbing bearing 7, between every group of upper supporting leg 17 and pole-climbing bearing 7, be installed with a slide bar 4, be installed with a punching hydraulic jack 5 on each slide bar 4.Slide bar 4 adopts the reinforcing bar of φ 30mm.The stage casing of every climbing frame 3 is provided with the adjustment screw rod 6 of a horizontal direction.
Such as Fig. 3, Fig. 4, Fig. 6, the structure of template part is, comprise and adopt the all-in-one-piece template 11 of cylindrical shape, circumference in template 11 is provided with shrinkage joint 9 one, shrinkage joint 9 duties are filled with little template, the shrinkage joint is equipped with liquid parting cylinder pressure 10 between 9 both sides, upper port in template 11 is provided with a plurality of funnels 8 of building along even circumferential, lower port in template 11 is provided with a circle activity basil 12, on template 11 inner surfaces, be fixedly connected with three groups of jacking bracket framves 13 along even circumferential, a fixed bearing 14 and a freely movable bearing 15 are set on every group of jacking bracket frame 13, fixed bearing 14 is welded on the jacking bracket frame 13, fixed bearing 14 is corresponding with adjustment screw rod 6 positions when building, be provided with a steel plate 16 between freely movable bearing 15 and the jacking bracket frame 13, the two ends of steel plate 16 are hinged with freely movable bearing 15 and jacking bracket frame 13 respectively; During normal pouring construction, punching hydraulic jack 5 is installed on the fixed bearing 14, in knockout course, punching hydraulic jack 5 is moved on the freely movable bearing 15 from fixed bearing 14, be fixedly connected with punching hydraulic jack 5 in order to overcome slide bar 4, so that the problem that template 11 can't radial contraction.
Such as Fig. 1, appendage includes three working platformes and guard shield up and down: (this platform segmentation is hinged on the template upper end to be used for the working platform 1 of concrete construction, be latticed platform, vertically suspention is propped up with strut during concreting at ordinary times); The working platform 2 23 (this platform welding is fixed on the outer border of hypomere of climbing frame 3, is similarly latticed platform) that is used for supporting leg 18 under assembling reinforcement construction and the dismounting; The working platform 3 24 (this platform welding is made by channel-section steel and steel plate at climbing frame 3 stage casing central parts, and has the hole of handling rock slag) that is used for operation template 11 and punching hydraulic jack 5; Be connected to the upper guard shield 19 between three groups of upper supporting legs 17; Be connected to the lower guard shield 20 between the supporting leg 18 under three groups (upper guard shield 19 and lower guard shield 20 are made by channel-section steel and steel plate, and have the hole of handling rock slag, and are welded on the up and down two ends of climbing frame 3).
The operating principle of apparatus of the present invention is, after finishing the C section and building, just need to carry out the D section and build,
The first step, template 11 is motionless, and climbing frame 3 and upper and lower supporting leg are moved down together.
Second step, climbing frame 3 is motionless, and template 11 is moved down.When needs template 11 moves down, first climbing frame 3 is fixed on (fixing by bolt and built-in bolt sleeve 1) on the concrete guard wall, punching hydraulic jack 5 is installed on the freely movable bearing 15.Such as Fig. 3, extract first the little template at 9 places, shrinkage joint during the demoulding out, then utilize liquid parting cylinder pressure 10 to shrink template 11, shrinkage joint 9 diminishes template 11 diameters is diminished, and deflection must not exceed the elastic deformation amount of template; Therefore do not hinder the moving radially of template because freely movable bearing 15 and template 11 are chain connections this moment, can reach the demoulding.This moment, template 11 broke away from the concrete guard wall (C section) of building, punching hydraulic jack 5 is started working, upper card chucking slide bar 4, lower Kathon CG is opened, hydraulic fluid port is drained the oil and (is controlled flow with flow control valve on the oil cylinder, thereby the control decrease speed), punching hydraulic jack 5 drives freely movable bearings 15 and also is with moving platen 11 to move down, finish a stroke after, lower card chucking slide bar 4, upper Kathon CG is opened, hydraulic fluid port oil-feed on the oil cylinder, piston and upper card move down, and carry out the next one after putting in place again and move down action, iterative cycles like this, punching hydraulic jack 5 can be with moving platen 11 to move down.Template 11 move down into next the section build station (the D section among Fig. 1) after, begin to support and open template 11, template 11 is fixed with D section rock retaining wall by bolt and built-in bolt sleeve 1 again, the liquid parting cylinder pressure 10 at place, shrinkage joint unclamps during formwork, template is upheld and is returned to original shape, the place installs little template at the shrinkage joint, and with the adjustment screw rod 6 on the climbing frame 3 template is outwards put in place on the top.
So the circulation through above-mentioned template 11 and climbing frame 3 moves down repeatedly, can realize from top to bottom continual carrying out of vertical shaft panelling construction.
The advantage of apparatus of the present invention is to have saved winch and a large amount of wire rope; Climbing frame 3 and template do not need external force to move down voluntarily, thereby concreting work can be carried out continuously; Panelling construction and sinking shaft construction can be carried out synchronously, mutually can not affect, thereby but the Effective Raise construction speed; Simple in structure, practical, connection and reasonable arrangement makes the shaft construction section more simple and convenient.
