Detailed Description
As shown in fig. 1 to 4, the shear wall composite formwork for an expansion joint capable of being quickly assembled and disassembled of the present invention includes a composite formwork and a plurality of opposite-pulling screws. The combined template comprises a steel template, a longitudinal steel square tube, a transverse steel square tube and a nut. The steel template is a steel plate, the steel template is a steel plate with a proper specification selected according to the design size of the shear wall at the expansion joint of the drawing, the specification of the steel template is 800mm multiplied by 2500mm multiplied by 2mm as an example, the steel template is selected, and the steel template is spliced according to the size of the shear wall. Vertical steel square tube and horizontal steel square tube be vertically and horizontally staggered's fixed connection respectively at the back of steel form, and vertical steel square tube and horizontal steel square tube cross connection department are equipped with the split screw hole, run through vertical steel square tube, horizontal steel square tube and steel form simultaneously to the split screw hole. In the implementation process, the spacing between the tension screw holes is calculated according to a calculation book to perform paying-off positioning (the spacing between the tension screws is 450mm horizontally and longitudinally according to the calculation), and then a longitudinal steel square tube is welded at the back of the steel template every 450mm according to the back ridge spacing calculated by the calculation book to fix the steel template into a whole and fix the vertical deformation of the steel template. Wherein the longitudinal steel square tube is a steel square tube with the diameter of 80mm multiplied by 40mm multiplied by 2 mm. The back of the steel template is welded with a transverse steel square tube at intervals of 450mm according to a positioning line, the rigidity and the integrity of the combined template are enhanced, wherein the transverse steel square tube is a steel square tube with the thickness of 50mm multiplied by 2mm, the steel square tube directly connected with the steel template is thicker, and if the transverse steel square tube is directly connected with the steel template, the transverse steel square tube adopts the thicker steel square tube. Then split screw holes are formed in the upper surface of the combined template according to the positions of the split screw holes, and the split screw holes simultaneously penetrate through the longitudinal steel square tube, the transverse steel square tube and the steel template. And then the nut is welded on the surface of the longitudinal steel square tube or the surface of the transverse steel square tube outside the split screw hole, and the screw hole of the nut corresponds to the split screw hole in position. In the embodiment, the nut is welded on the outer side of the split bolt hole on the surface of the transverse steel square tube. Of course, if the transverse steel square tube is directly connected to the back of the steel formwork, and the longitudinal steel square tube is vertically connected to the surface of the transverse steel square tube, the nut is welded to the surface of the longitudinal steel square tube outside the split screw hole. The opposite-pulling screw rod can pass through the opposite-pulling screw hole of the combined template to tighten and position the position of the combined template. The steel form upper end still is connected with the U-shaped rings that are used for hoisting the built-up form, is equipped with two U-shaped rings in this embodiment, and two U-shaped rings weld respectively at the back of steel form upper end, and every U-shaped ring simultaneously with one of them vertical steel square tube upper end both sides surface welded fastening, can strengthen the connection stability of U-shaped ring like this.
The construction process can be implemented according to the following steps: (1) hoisting the combined template to the designated position of the expansion joint, and primarily fixing the combined template by placing a steel square tube (or wood imitation) and a supporting device at the rear side at the two ends of the combined template in a padding way; (2) installing and fixing a wood template on the inner side of the expansion joint shear wall, adjusting the positions of the wood template and the combined template by a pry bar according to a wall position line and a starting and stopping line of the template, forming a hole at the corresponding position of the wood template and installing a split screw sleeve, enabling a split screw to penetrate through the split screw sleeve from one side of the wood template and be screwed into a nut of the combined template until the split screw protrudes out of the nut by more than 50mm, adjusting the split screw to be approximately horizontal, measuring the verticality and correcting the elevation by a supporting plate, enabling the verticality, the levelness and the elevation to meet the design requirements, immediately screwing a bolt after the inner template is in place by a steel pipe, and tightening and fixing the combined template and the wood template (figures 5-6); (3) a plug template (the plug template is also a wood template) is arranged on the side surface, the joint of the template is tight, and slurry leakage during concrete pouring is prevented; (4) then pouring concrete; (5) removing the formwork of the shear wall formwork at the expansion joint when the strength of the concrete reaches a formwork removal standard, removing pipe clamps at two sides, taking down the short steel pipes, screwing out the counter-pulling screw rods, removing the counter-pulling screw rods and the fixing devices at two ends, taking down the long steel pipes, sequentially removing the inner side wood formwork and the lateral plug formwork, and finally removing the combined formwork; (6) when dismantling the split screw, earlier with the instrument to split bolt unscrewing, then through rotatory split screw, unscrew the split screw from the composite mold board, treat all to pull the screw and all back of unscrewing, dismantle the composite mold board promptly, the handling is placed to the assigned position to it is clean, so that use next time.
The following matters are noted during construction: (1) at the joint of the wood template and the combined template, a steel template in the combined template is required to wrap the wood template so as to prevent slurry leakage caused by overlarge slab joints; (2) before the die assembly, whether embedded pipe fittings such as reinforcing steel bars, water and electricity are omitted or not is checked, and the method is correct; (3) after the templates are installed, checking whether the wood template and the plug template, and the plug template and the combined template are tight, firm and reliable, and preventing the phenomena of slurry leakage and slab staggering; (4) after the template is installed, whether the fasteners, the bolts and the inclined struts are fastened and stable or not and whether the abutted seams and the lower openings of the template are tight or not are comprehensively checked.
The above embodiments are only preferred embodiments of the present invention, and the structure of the present invention is not limited to the forms of the above embodiments, and any modifications, equivalents and the like within the spirit and principle of the present invention should be included in the protection scope of the present invention.
