Description
Technical Field
The invention relates to the field of concrete construction, in particular to a method for supporting a shaping template of an expansion joint between residential unit buildings.
Background
The traditional method for supporting the expansion joint between the residential unit buildings is to fill a polystyrene board at the expansion joint to separate a formwork or divide the formwork into two parts. The method for filling the polystyrene boards often causes the instability of a template system, and the expansion joints are filled with the polystyrene boards which are made of flexible materials, so that the template is easy to deviate in the concrete pouring process, and the problems of poor verticality and flatness are caused. Furthermore, the quality problem of the mold explosion can occur, concrete is wasted, a large amount of manual work is needed for processing, and materials and labor are wasted. Meanwhile, the template at the position of the expansion joint in the traditional method is very troublesome to dismantle, the damage to the template is very large, and a large amount of loss of the template is caused. The method of twice formwork erecting pouring can cause construction period waste, and meanwhile, the quality problems of poor wall perpendicularity and flatness occur during the second formwork erecting pouring.

(2) two inner templates positioned at the expansion joint and two outer templates positioned at the outer sides of the two inner templates are erected, and then clamping devices for the inner and outer templates of the expansion joint are installed on the outer side of the outer template at one side of the outer template at intervals in a longitudinal and transverse mode;
(3) when the clamping device for the inner and outer templates of the expansion joint is installed, a sleeve sequentially penetrates through the two outer templates and the two inner templates from the outer side of the outer template on one side along the plane direction perpendicular to the outer template, then extends out of the outer template on the other side, the position of the sleeve is adjusted, a strip-shaped hole in the sleeve respectively extends out of the two inner templates along the two ends of the length direction of the sleeve, then an inner tension rod is operated at one end of the sleeve, the two clamping rods at the insertion end of the inner tension rod are rotated into the accommodating groove, the insertion end of the inner tension rod is inserted into the sleeve at one side of the insertion end of the inner tension rod, when the end, far away from the hinge shaft, of the clamping rod at the insertion end of the inner tension rod is positioned at the strip-shaped hole, the two clamping rods respectively rotate to penetrate through and extend out of the strip-shaped hole under the spring force of the torsion spring by rotating the inner tension rod, then the inner tension rod is screwed on the inner tension screw sleeve, then another inner tension rod is arranged at the other end of the sleeve according to the method;
(4) the outer tightening screw sleeves are respectively screwed at the two ends of the sleeve, the outer tightening screw sleeves are screwed to enable the outer tightening screw sleeves to be abutted against the outer side surface of the outer template at one side, the relative positions of the outer tightening screw sleeves at the two ends are adjusted to limit the outward movement of the two outer templates, then the inner tightening screw sleeves are screwed to adjust the distance between the inner tightening screw sleeves and the corresponding clamping rods, the clamping rods are abutted against the side surfaces of the inner templates at one side where the clamping rods are located, the inner tightening screw sleeves are abutted against the end parts of the sleeve at one side where the inner tightening screw sleeves are located, and the inner templates are further limited in the inward movement direction;
after concrete on the side walls on two sides of the expansion joint is solidified, the inner tension rod is dismantled, the inner tension screw sleeve is screwed firstly to enable the inner tension screw sleeve to move towards the direction away from the sleeve, then the inner tension rod moves towards the sleeve and stretches into the sleeve, so that the clamping rod and the inner template on one side of the clamping rod are separated, the pull rope is pulled outwards, the pull rope drives the pull ring to slide towards the direction of the limiting bulge on the clamping rod, the clamping rod can be driven to move towards the direction of the accommodating groove in the sliding process of the pull ring, until the clamping rod and the pull ring are accommodated in the accommodating groove, and then the inner tension rod is pulled outwards until the inner tension rod is pulled out from the sleeve.
2. The method of claim 1, wherein the method comprises the steps of: the outer side of the dismounting end of the inner tension rod is provided with a circular ring, the ring of the circular ring is sleeved with two connecting rings which can move along the length direction of the ring of the circular ring, and two pull ropes on the same side are fixedly connected with the two connecting rings respectively.
