With reference to fig. 1 and 2, the two ends of the panel 22 facing the panel 22 are bolted to the foundation formwork 1, and the two pillars are outlined by the panel 22 and the foundation formwork 1. The surface of the panel 22 facing the pier is defined as profile 222 and the surface of the panel 22 facing the gap is defined as gap surface 221. A U-shaped plate 223 is fixed to the middle of the gap surface 221, and the base 21 slides on the U-shaped plate 223 of the two panels 22.
A threaded rod 25 (threads not shown) acts as a drive to move the wedge block 23, guide block 24 and panel 22. When the mold is retracted, the constructor mainly operates the bottom screw rod 25. To facilitate the operation of the constructor from one side of the gap between the two pier studs, the axis of rotation of the threaded rod 25 is set horizontally and parallel to the gap plane 221, with its end close to the gap side.
The guide block 24 is in the form of a rectangular trapezoid, and a surface corresponding to the oblique waist of the rectangular trapezoid is a guide surface 241 provided on the side of the guide block 24 away from the panel 22 connected thereto. The same panel 22 is provided with an equal number of guide blocks 24 on both sides of the U-shaped plate 223 (here, one guide block is taken as an example). In order to ensure the balanced stress on the two sides of the gap template 2, two guide blocks 24 on the same panel 22 are arranged in a mirror symmetry mode relative to the center of the base 21; the guide block 24 is mirror symmetrical to the guide block 24 on the other panel 22 and its mirror plane is parallel to the slot plane 221. The guide surface 241 is vertical to the theoretical intersection line of the slit surface 221 and is located on the side of the guide block 24 close to the base 21.
The wedge blocks 23 are provided in two numbers and are respectively screwed on the threaded rods 25. The threaded rod 25 is threaded in opposite directions at opposite ends of the base 21, so that the two wedge blocks 23 move in parallel and in opposite directions. As shown in fig. 3, the wedge block 23 includes a body 231 and a threaded portion 232, and in conjunction with fig. 4, the body 231 is in the shape of an isosceles trapezoid, and an inclined surface corresponding to a waist of the isosceles trapezoid is parallel to the adjacent guide surface 241. The main body portion of the threaded portion 232 is tubular and threaded on its inner wall. The body 231 is formed with a circular through hole into which a main body portion of the screw portion 232 is inserted, a flange is fixed to one end of the screw portion 232, and the screw portion 232 is flange-connected to the body 231.

The slide rail 262 and the slide bar 261 are both long and are both arranged along the gradient direction in which the guide surface 241 is inclined. The circumferential side wall of the slide rail 262 is provided with a sliding groove 263 arranged along the length direction of the slide rail 262, and the sliding groove 263 penetrates through the end surfaces of the two ends of the slide rail 262. Two edges of one side of the opening of the sliding groove 263 are fixedly connected with blocking edges 264 arranged along the length of the sliding rail 262, so that the cross section of the sliding groove 263 is T-shaped. The cross-section of the slide 261 is the same as the T-shape so that the slide assembly 26 can bring the guide blocks 24 closer together.
When the threaded rod 25 rotates, the two wedge blocks 23 are driven to slide close to or away from each other against the guide block 24, so that the guide block 24 drives the two panels 22 to smoothly close to or away from each other.
As shown in fig. 2, the threaded rod 25 is sleeved with an annular anti-rotation wheel 5. The position of the threaded rod 25, which is sleeved with the anti-rotation wheel 5, is provided with a smooth circumferential surface, as shown in fig. 5, four transmission ridges 251 are fixedly connected to the circumferential surface, and the length direction of the transmission ridges 251 is parallel to the axis of the threaded rod 25 and is uniformly distributed circumferentially with the axis of the threaded rod 25 as the center. The inner peripheral wall of the anti-rotation wheel 5 has the same diameter as the threaded rod 25, and four micro grooves 51 are formed in the inner peripheral wall. The transmission ridge 251 extends into the micro-groove 51 and can swing left and right in the micro-groove 51 along with the rotation of the threaded rod 25, so that the anti-rotation wheel 5 can rotate along with the rotation of the threaded rod 25, but a certain margin is reserved, and the anti-rotation wheel and the threaded rod can rotate relatively at a small angle.
The periphery wall rigid coupling of anti-rotation wheel 5 has a plurality of arris boards 52 that prevent changeing, prevents changeing arris board 52 and uses the axis of anti-rotation wheel 5 as the even circumference distribution of center.
Referring to fig. 1 and 5, a baffle 3 for shielding the threaded rod 25 is arranged above the base 21, so that impurities can be prevented from falling on the threaded rod 25 to influence the transmission of the threaded rod 25. The lower surface of the baffle 3 is fixedly connected with a clamping plate 31 inserted between two adjacent anti-rotation edge plates 52 for limiting the rotation of the threaded rod 25 after the distance between the two panels 22 is determined. The rotation allowance of the anti-rotation wheel 5 can ensure that the anti-rotation ridge plate 52 can not be aligned with the clamping plate 31, so that the situation of incapability of inserting is avoided.
As shown in fig. 2 and 6, the two ends of the threaded rod 25 are respectively rotatably connected with a rectangular block-shaped connecting table 4. When the clamping plate 31 is inserted between two adjacent anti-rotation edge plates 52, one top surface of the connecting table 4 is kept flush with the bottom surface of the baffle 3, and the baffle 3 is connected with the connecting table 4 through bolts. Make threaded rod 25 and baffle 3 support each other, the relative position of fixed threaded rod 25 and baffle 3 simultaneously avoids baffle 3 and prevents changeing 5 separation at the in-process of vibrating.
