One side of the inner side template 4 of the arc-shaped beam and one side of the outer side upper template 5 of the arc-shaped beam are both provided with installation grooves, and the inner wall of the installation groove is clamped and connected with the vertical wood square 3. The inner side template 4 of the arc-shaped beam and the outer side upper template 5 of the arc-shaped beam are fixedly connected with the vertical wood square 3 through the water stop bolt 1. The water stop bolt 1 includes a water stop bolt screw rod 6, and both ends of the water stop bolt screw rod 6 are threadedly connected with fastening nuts 8. One side of the two fastening nuts 8 is in tight contact with one side of the vertical wood square 3, and both ends of the middle part of the water stop bolt screw rod 6 are slidably connected with butterfly buckles 7.

[0027] The butterfly buckle 7 includes a steel sleeve 9, and steel arc buckles 10 are fixedly connected on both sides of the steel sleeve 9. The inner wall of the steel arc buckle 10 is engaged with the middle part of the arc-shaped steel bar 2. The above-mentioned butterfly buckle 7 is a customized buckle. Since the butterfly buckle used in common bolts is not suitable for fixing steel bars, a customized butterfly buckle 7 is adopted according to the shape and size of the steel bars. It is not only simple to process, but also the reinforced steel bars are more firmly.

[0028] An adjustment groove is provided in the middle of the vertical wooden square 3, and a hanging plate 11 is slidably connected inside the adjusting groove. A hanging buckle 12 is fixedly installed in the middle of one side of the hanging plate 11, and locking rods 13 are inserted and connected at both ends of one side of the hanging plate 11. One end of the two locking rods 13 is fixedly connected with an elastic sheet 14, and a number of evenly distributed limiting holes 15 are provided at both ends of one side of the vertical wooden square 3. An expansion cavity is provided at one end of the inner wall of the limiting hole 15, and the inner wall of the expansion cavity is snap-fitted and connected with one side of the elastic sheet 14. By setting structures such as the hanging plate 11 and the hanging buckle 12, the arc-shaped steel bar 2 is initially limited, which is convenient for the subsequent snap-fitting installation between the arc-shaped steel bar 2 and the steel arc buckle 10.

When it is found that the local spacing value is abnormal, the water stop bolt 1 at that position is adjusted to ensure that the spacing between the inner template 4 of the curved beam and the outer upper template 5 of the curved beam is stable.

[0031] The present invention also provides a construction method for a cast-in-place concrete arc-shaped stand formwork reinforcement device, comprising the following steps:

[0032] Step 1: According to the design drawings and on-site construction requirements, the inner side template 4 of the curved beam and the outer side upper template 5 of the curved beam of appropriate size are manufactured, and the templates are formed by bending after being slotted by a slotting machine, and are installed in place after the templates are manufactured;

[0033] Step 2: Lay the vertical wood 3 in the installation groove on the plate surface of the inner template 4 of the curved beam and the outer upper template 5 of the curved beam, and connect the inner template 4 of the curved beam, the outer upper template 5 of the curved beam and the vertical wood 3 through the water stop bolt screw 6, and slide the butterfly buckle 7 on both ends of the water stop bolt screw 6, and then rotate the assembly fastening nut 8 on the outer side of the butterfly buckle 7 to achieve the installation and fixation of the vertical wood 3 to form a secondary keel of the vertical support;

[0034] Step 3: Slide the mounting plate 11 to a suitable position close to the butterfly buckle 7, and then push the locking rod 13 so that the elastic sheet 14 is engaged with the expansion cavity to complete the fixing of the mounting plate 11, and then engage the middle part of the arc-shaped steel bar 2 with a plurality of mounting buckles 12 to limit the arc-shaped steel bar 2;

[0035] Step 4: Separate the arc-shaped steel bar 2 from the hanging buckle 12, and snap the arc-shaped steel bar 2 into the inner wall of the steel arc-shaped buckle 10 to complete the installation of the reinforcement device;

[0036] Step five, slide the two sides of the bottom of the distance measuring plate 16 to the top of the inner formwork 4 of the curved beam and the top of the outer upper formwork 5 of the curved beam respectively, then push the distance measuring plate 16 to slide, read the scale 23 reading through the observation window, and measure the distance between the inner formwork 4 of the curved beam and the outer upper formwork 5 of the curved beam. When it is found that the local distance value is abnormal, adjust the water stop bolt 1 at that position to ensure that the distance between the inner formwork 4 of the curved beam and the outer upper formwork 5 of the curved beam is stable; then fill the gap between the inner formwork 4 of the curved beam and the outer upper formwork 5 of the curved beam with building materials.

[0037] When the present invention is used, first, according to the design drawings and on-site construction requirements, the inner side template 4 of the arc beam and the outer side upper template 5 of the arc beam with appropriate sizes are manufactured, and the templates are formed by bending after being slotted by a slotting machine, and are installed in place after the templates are manufactured;

[0038] The vertical wood square 3 is laid in the installation groove on the plate surface of the inner template 4 of the arc beam and the outer upper template 5 of the arc beam, and the inner template 4 of the arc beam, the outer upper template 5 of the arc beam and the vertical wood square 3 are connected through the water stop bolt screw 6, and the butterfly buckle 7 is slidably mounted on both ends of the water stop bolt screw 6, and then the fastening nut 8 is rotated and assembled on the outer side of the butterfly buckle 7 to realize the installation and fixation of the vertical wood square 3 to form a secondary keel of vertical support;

[0039] Slide the mounting plate 11 to a suitable position close to the butterfly buckle 7, and then push the locking rod 13 so that the elastic sheet 14 is engaged with the expansion cavity to complete the fixing of the mounting plate 11, and then engage the middle part of the arc-shaped steel bar 2 with a plurality of mounting buckles 12 to limit the arc-shaped steel bar 2; separate the arc-shaped steel bar 2 from the mounting buckle 12, and engage the arc-shaped steel bar 2 with the inner wall of the steel arc buckle 10 to complete the installation of the reinforcement device;

The top of the inner template 4 of the arc beam or the outer template 5 of the arc beam is clamped and fixed by one side of the inner wall of the ranging plate 16 and the clamping plate 19. At this time, the ranging spring 20 pushes the ranging roller 21 to make it press against one side of the outer template 5 of the arc beam or one side of the inner template 4 of the arc beam, and then pushes the ranging plate 16 to slide. During the activity, the pushing effect of the pushing spring 17 is used. To ensure the stable fitting connection of the distance measuring plate 16, the movement of the distance measuring roller 21 during the movement drives the scale 23 to move, and the indication of the scale 23 is read through the observation window to measure the distance between the inner template 4 of the curved beam and the outer upper template 5 of the curved beam. When it is found that the local distance value is abnormal, the water stop bolt 1 at that position is adjusted to ensure the stability of the distance between the inner template 4 of the curved beam and the outer upper template 5 of the curved beam; and then fill the gap between the inner template 4 of the curved beam and the outer upper template 5 of the curved beam with building materials.
