Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fair-faced concrete pouring, and more particularly relates to a fair-faced concrete pouring forming device. BACKGROUND

[0002] Fair-faced concrete pouring must use a formwork, which serves as a temporary support structure to ensure that the concrete maintains precise geometric shapes and design dimensions during the setting process, and a high-quality fair-faced formwork can directly form a smooth and flat concrete surface, saving the secondary plastering process and achieving the effect of 'demolding as finishing'.

[0003] The currently used fair-faced concrete pouring formwork still has the following problems: 1. Generally, the formwork does not have an auxiliary butt joint function, which leads to misalignment of adjacent formworks after connection, affecting the pouring effect of the concrete; 2. When positioning the formwork, the worker needs to tighten a large number of bolts, which is inconvenient for the worker to quickly position the formwork, increasing the installation time of the formwork; 3. It is inconvenient for the worker to reinforce the connected formwork, which leads to gaps between adjacent formworks after connection, making the connected adjacent formworks unstable. SUMMARY

[0025] In this embodiment of the disclosure, such as Figures 6 to 8 As shown, the clamping and positioning mechanism 300 includes: a U-shaped clamping frame a301 and a U-shaped clamping frame b302; the U-shaped clamping frame a301 is installed between two rings of rectangular limiting bars 102; the U-shaped clamping frame b302 is installed between the two rings of rectangular limiting bars 102, and the U-shaped clamping frame b302 is located in front of the U-shaped clamping frame a301, and the inner side of the U-shaped clamping frame b302 contacts the inner side of the U-shaped clamping frame a301; the clamping and positioning mechanism 300 also includes: a rectangular connecting rod 303 and a circular mounting shaft 304; there are two rectangular connecting rods 303, and the two rectangular connecting rods 303 are fixedly installed on the rear U-shaped clamping frame a301, and the two rectangular connecting rods 303 is also inserted into the U-shaped clamping frame b302 on the front side; there are two circular mounting shafts 304, and the two circular mounting shafts 304 are fixedly mounted on the two rectangular connecting rods 303; the clamping and positioning mechanism 300 also includes: movable positioning plates 305 and rectangular magnets 306; there are two movable positioning plates 305, and the two movable positioning plates 305 are mounted on the outside of the two circular mounting shafts 304, and the two movable positioning plates 305 are respectively provided with limit slots 3051; there are four rectangular magnets 306, and the four rectangular magnets 306 are fixedly mounted on the front and rear sides of the two movable positioning plates 305, and the two rectangular magnets 306 on the rear side are fixedly connected to the two rectangular connecting rods 303; Its specific function is as follows: because the U-shaped clamping frame a301 is installed between the two rings of rectangular limiting bars 102, and the U-shaped clamping frame b302 is installed between the two rings of rectangular limiting bars 102, and the two rectangular connecting rods 303 are inserted into the front U-shaped clamping frame b302, it plays a clamping and positioning role for the ring of casting mold 101; and because the two circular mounting shafts 304 are fixedly installed on the two rectangular connecting rods 303, and the two movable positioning plates 305 are installed outside the two circular mounting shafts 304, they play a limiting role for the two rectangular connecting rods 303, making the connection between the U-shaped clamping frame a301 and the U-shaped clamping frame b302 more secure; In addition, since the two movable positioning plates 305 are respectively provided with limiting slots 3051, the two movable positioning plates 305 can slide on the outer wall of the two circular mounting shafts 304; and since the four rectangular magnets 306 are fixedly installed on the front and rear sides of the two movable positioning plates 305, and the two rectangular magnets 306 on the rear side are fixedly connected to the two rectangular connecting rods 303, the two movable positioning plates 305 after movement have a limiting effect.

[0027] The specific usage and function of this embodiment are as follows: In use, the worker first places four casting templates 101 together, then installs U-shaped clamping frames a301 and b302 on the outside of the four casting templates 101. The cast templates 101 together provide clamping and positioning, allowing two movable positioning plates 305 and two rectangular connecting rods 303 to be inserted into the U-shaped clamping frame b302. This limits the position of the two rectangular connecting rods 303, ensuring proper contact between the U-shaped clamping frames a301 and b302. After connection 302, the connection is more secure. Then, rotate the two movable positioning plates 305 ninety degrees, and then move the two movable positioning plates 305 so that the corresponding two rectangular magnets 306 contact the two rectangular connecting rods 303. Because the auxiliary docking plate 201 is slidably installed inside the casting mold 101, and the outer end of the auxiliary docking plate 201 is flush with the outer end of the casting mold 101, it protects the outer end of the auxiliary docking plate 201, ensuring that the auxiliary docking plate 201 can be smoothly inserted into the other...
