Abstract
The invention discloses a template supporting system for a narrow space of a building concrete structure. The template supporting system comprises two pieces of C-shaped steel which are symmetrically arranged, wherein through holes are formed in the center of upper and lower pressing plates; a lead screw is arranged in the through holes; a wedge-shaped supporting mechanism is serially arranged on the lead screw; and the template supporting system comprises the following two working positions, namely (1) an opening working position, wherein the lead screw is rotated, so that a wedge-shaped pin moves upwards, a wedge-shaped supporting pin opens the matched movable supporting pairs, the movable supporting pairs push the two pieces of C-shaped steel on two sides to be ejected outwards simultaneously so as to reach the opening working position, and (2) a shrunk working position, wherein the lead screw is reversely rotated, so that the wedge-shaped pin moves downwards and retracts from the matched movable supporting pairs, the movable support is reset inwards under the action of own gravity, and the two pieces of C-shaped steel on two sides are reset inwards under the action of a tension spring so as to reach the shrunk working position. The novel template supporting system for the narrow space of the building concrete structure can be applied to the building process of expansion joints in double shear walls, facade models with narrow spaces in buildings and the like.
Description
Technical field
The present invention relates to a kind of formwork bracing system that is used for building concrete structure small space, belong to building field.
Background technology
At present, building trade has obtained tremendous development, and the modeling structure of building is also more and more, more and more beautiful.For building concrete structure small space,, need use formwork bracing system as having outer facade moulding of small space etc. within the walls shrinkage joint of double shear, the building.
Traditional formwork bracing system mainly is tub that timber is processed; Be folded with foamed material wherein; The support system of this structure is prone to cause concrete to overflow in practice of construction, finally causes many, physical form and defectives such as expected discrepancy is big of foreign material in the malformation seam, and clears up difficult; And cause the serious waste phenomenon of timber and cystosepiment.
To the problems referred to above; New formwork bracing system has appearred; A kind of rhombus jack and cascaded structure thereof are disclosed referring to Chinese utility model patent CN201762057U; Its rhombus jack comprises top end, following top, two go up left support arm, two down left support arm, two go up right support arm and two right support arm down, go up left support arm and be connected with top end for said two with two upper ends of going up right support arm; Said two last left support arms and two upper ends of going up right support arm form intermeshing detent projection; Said two down left support arm with two down the lower end of right support arm is connected with top down, said two down left support arm and two form intermeshing detent projection in the lower end of right support arm down, it is hinged that a left jointed shaft is passed through in said two upper ends of going up left support arm under left support arm lower end and two; Go up right support arm lower end the upper end of right support arm is hinged through a right jointed shaft down with two for said two, said left jointed shaft, right jointed shaft are through screw mandrel connection.During use, through rotary screw, two jointed shafts are automatically connected in the support arm rotation on the jointed shaft with the while forced belt, outwards eject when making top end and following headwind.
Yet; There are following shortcoming in the rhombus jack and the cascaded structure thereof of said structure: (1) for general double shear wall, it has certain height, thereby the general needs in it are used the cascaded structure of a plurality of rhombus jack; Need the scene to assemble, relatively waste time and energy; (2) because the support arm of rhombus jack is hinged through left and right jointed shaft; And left and right jointed shaft connects through screw mandrel; Therefore; Coming directly towards the power that receives up and down can finally drop on the screw mandrel, thereby above-mentioned support system be high to the requirement of strength of screw mandrel through support arm, the left and right sides jointed shaft of both sides.
