Description
Technical field
The present invention relates to one-sided body of wall formwork system, particularly relate to the assembled portable truss single side formwork system construction method of removable rotating beret truss.
Background technology
Cellarway is because of technique and function needs, often become U-shaped mouth, side wall is higher and be gradual change type, exterior wall and land red-line close together, simultaneously along with the development of multiple material handling method of deep foundation pit, vertical supporting is widely adopted, and the construction of underground passage side wall adopts bilateral formwork to realize, and must adopt single side formwork.
Traditional single side formwork technique adopts steel pipe to set up the support system of framed bent as template, this technique uses steel pipe quantity large, and the cycle of setting up is long, and one time formwork height is lower, and easily there is the defects such as Form floating, swollen mould, concrete wall surface evenness, verticality difference, construction quality is difficult to ensure.For highly larger body of wall formwork, difficulty of construction is larger.Triangular shape formwork system after improvement can solve the larger body of wall formwork of one-sided height, it is disposable that to install form height high, and staying of horizontal construction joint can be reduced and establish quantity, but when running into as gradual change type bodies of wall such as U-type groove, template is set up and fix just not satisfactory.The big basement one side formwork construction of domestic routine all adopts shaped steel to do support system, and often adopt No. 20 i iron for supporting, No. 12 channel-section steels are the template system of keel.It is large that this template system has shaped steel processing capacity, easily tens tons even nearly hundred tons, cost is very high, and the engineering had has again car ramp, airshaft, elevator shaft and staircase etc. along outer wall of basement, meet this situation, type steel support system not easily decomposes use, as half-hearted process, often meet elevator shaft and airshaft place, form the weak link in whole outer wall template system, once burst-mode, by the Forming Quality of the whole exterior wall concrete of impact, very easily form the cold seam of construction, cause seepage, so the applicability of this template system is not strong.
Given this, need a kind of speed of application of invention at present badly fast, realize the horizontal movement of supporting die system and rotation, can differing heights be adapted to, the body of wall single side formwork system in the gradient and cross section and construction method.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of easy construction is provided, rotatably, removable, differing heights, the gradient and cross section side wall formwork needs can be adapted to, the practical assembled portable truss single side formwork system construction method of beret truss can be repeated.
For achieving the above object, present invention employs following technical scheme:
The assembled portable truss single side formwork system construction method of this beret truss, comprises the following steps:
1) billet is fixed: first lay billet on base plate top before construction, billet is fixed on substrate by sill anchor, and billet length is determined according to Track desigh length;
2) rail beam is installed: by rail beam lifting to precalculated position on billet, fix bottom flange with bolt; Then lift top flange backing plate bolt to fix;
3) beret truss truss installa-tion: on-site consolidation beret truss, is assembled into beret truss truss, beret truss truss bottom end connection of rotating hinged-support; Lift whole beret truss truss on track, tighten the connecting bolt on hinged-support, fix by temporary support;
4) side wall model sheetinstallat: first remove temporary support, mobile beret truss truss is to precalculated position, unclamp bearing connecting bolt, rotate truss to precalculated position, screw rod one end with disrance sleeve is anchored in fender post, and the other end is by backing plate, with bolts in beret truss panel point, on side wall template precalculated position, both sides, reserved screw rod hole, seals with waterproofing materials after screw rod is fixing;
5) additional support is installed: additional support is the scalable steel pipe of combined type, each reserving hole of both sides steel pipe, and outside is provided with backing plate, fixes after length adjustment with bolt; Additional support one end welding additional support backing plate is bolted in beret truss panel point, and the other end is welded on bottom steel backing plate, and arranges single angle baffle plate bottom being close to, and adopts bolt to fix.
As preferably: step 1) in billet width be that outermost additional support bottom position expands 200 ~ 400mm outward.
As preferably: step 2) described in rail beam be arranged on above billet, adopt sill anchor to fix, and track pad be set at Liang Shangyiyuanchu.
As preferably: step 3) described in rotating hinge rest base be provided with universal wheel, whole bearing is placed on rail beam, can carry out the movement of vertical and horizontal.
As preferably: step 5) described in when side wall formwork template is installed, beret truss truss and the upper and lower three screw rod middle wall body of the fixing employing of side wall template arrange without other built-in fittings and are connected, and on side wall scope inner screw, cover has disrance sleeve.
The invention has the beneficial effects as follows:
(1) after leading portion wall construction, without the need to carrying out dismounting again, only need remove screw rod, arrive next section of body of wall position along rail moving, then be fixed formwork, construction period obviously shortens.
(2) run into variable cross-section body of wall, dismountable baffle plate, carry out transverse shifting, and carry out the rotation of angle as required, without the need to readjusting dismounting, easy construction, operation greatly reduces.
(3) the upper and lower three place's screw rods of whole formwork system are fixing fixes with additional support, and upper screw is provided with disrance sleeve at side wall place, and construction terminates rear screw rod and can simply pull out, and little to body of wall disturbance, component all can reuse, and construction quality is high, cost-saving.
