Description

TECHNICAL FIELD

[0001] The utility model relates to frame structure deformation joint formwork system. BACKGROUND

[0002] In the construction, in order to prevent the thermal expansion and cold shrinkage caused by temperature change from causing the reinforced concrete frame structure to produce cracks or damage, the expansion joint is often set in proper position during construction, and after setting the expansion joint, two parallel structure double columns are formed on the two sides of the expansion joint, and the net distance between the double columns is generally 150mm; during the formwork construction of the double columns, since the column formwork generally uses 15mm thick plywood, the double column spacing is only 13mm after deducting the thickness of two formworks, and 50mm*100mm wooden frame keel and Φ48*3.2 steel pipe cannot be installed into the double column for effective fixation. There are two kinds of traditional super-close double column formwork construction methods, one is to fill foam board between the double column formworks, that is, after the double column formworks are supported, workers fill foam board between the double column formworks according to their own experience. The disadvantages of this method are: personal factors have great influence, and after the foam board is filled and fixed, concrete is poured, since the foam board is not effectively fixed, the lateral pressure generated during the concrete pouring and vibrating process can easily cause the foam board to loosen and fall off, and further cause local formwork expansion and formwork explosion.

[0003] The second conventional method is to first support the formwork of one column, then fix the wooden square back rafter, steel pipe and tension bolt, after the reinforcement is correct, concrete is poured, after the column is demoulded, the other side formwork is supported, foam board is filled in the double column joint, and the other side is continuously poured, and the foam board is not removed. The disadvantages of this method are: long construction period, double columns cannot be constructed at the same time, segmented construction increases the construction difficulty, causes the increase of construction period and cost, and the quality of formwork cannot be effectively guaranteed.

[0027] As shown in the drawings, Figure 5 , Figure 6As shown, this application provides a second embodiment, which is basically the same as the first embodiment, except that: the left and right adjustment parts 14 both include abutment rods 141 and upper and lower clamping rods 142. The abutment rods 141 and upper and lower clamping rods 142 both pass through the through groove of the first side template 4 laterally. Both ends of the abutment rods 141 and upper and lower clamping rods 142 are provided with bidirectional threaded sections, and clamping plates 15 are threadedly connected to the bidirectional threaded sections.

[0028] The specific improvements mentioned above are as follows: Figure 5 , Figure 6 As shown, both the left and right adjustment parts 14 include an abutment rod 141 and upper and lower clamping rods 142. The abutment rod 141 and the upper and lower clamping rods 142 both pass through the through groove of the first side template 4 laterally. Both ends of the abutment rod 141 and the upper and lower clamping rods 142 are provided with bidirectional threaded sections. Clamping plates 15 are threadedly connected to the bidirectional threaded sections. The position of the abutment rod 141 and the upper and lower clamping rods 142 is determined by the size of the triangular support position formed by the unfolding and folding of the support part 13, and then the clamping plates 15 are used to fix the position of the abutment rod 141 and the upper and lower clamping rods 142.

[0029] The working principle is as follows: First, the distance between the two templates is determined in advance, i.e., the width of the expansion joint is determined. Since the two first-side templates 4 have a certain thickness, when adjusting the telescopic rod 134, the determined expansion joint width needs to be subtracted from the thickness of the two first-side templates 4 to initially determine the overall length of the telescopic rod 134. The abutment plate determines the position of the sliding rod 133 in the slide groove 132 by inserting the rod into the insertion hole and positioning hole, thus determining the overall length of the hinge plate 131 and the sliding rod 133. Based on the position of the hinge end of the sliding rod 133 and the telescopic rod 134, the position of the abutment rod 141 is adjusted, and the hinge end abuts against the upper surface of the abutment rod 141. The position of the upper and lower clamping rods 142 is adjusted based on the position of the telescopic rod 134, and the end of the telescopic rod 134 is inserted into and abuts against the upper and lower clamping rods 142. Thus, through the abutment rod 141 and the upper... The lower clamping rod 142 stabilizes and limits the sliding rod 133 and the telescopic rod 134, achieving stable triangular support. Each of the opposite first side templates 4 is equipped with a corresponding triangular support. The triangular supports support each other and simultaneously connect the opposite first side templates 4. Then, the front and rear main templates 6 and the second side templates 5 are installed and enclosed to form the corresponding pouring cavity. Concrete is poured into the pouring cavity. After the concrete has cured, the second side template 5 is removed. By rotating the adjusting component, the triangular support loses its abutment force, and the telescopic rod 134 and the sliding rod 133 lose the restriction of the abutment rod 141 and the upper and lower clamping rods 142, so that the included angle between them changes from an acute angle to an obtuse angle. Then, the first side templates 4 are removed from the expansion joint by hoisting and fixing the traction rope to the corresponding first side template 4. Finally, the front and rear main templates 6 are removed.
