< first embodiment >

As shown in fig. 2, the template chuck 100 provided by the present utility model includes a left clamp 1, a right clamp 2, and a hammering nut 3. The left clamp 1 comprises a screw 11 extending along the X direction and a left positioning block 12, and the left positioning block 12 is fixedly connected to one end of the screw 11. The right pliers 2 are sleeved at the other end of the left pliers 1 far away from the left positioning block 12, and the right pliers 2 and the left positioning block 12 of the left pliers 1 form a clamp with a preset distance, and the clamp is used for clamping any two of the tool type templates 200 and the bulk wood templates 300. The hammering nut 3 is sleeved on the screw rod 11 of the left clamp 1, and the hammering nut 3 is arranged between the right clamp 2 and one end of the screw rod 11 and used for limiting the position of the right clamp 2, so that the clamps keep a preset distance and the loosening of the template clamp 1 is prevented.

For convenience of explanation, in the embodiment of the present utility model, the extending direction of the screw 11 of the left clamp 1 is defined as the X direction, and the position of the positioning block 12 of the left clamp 1 is defined as the front, and vice versa.

As shown in fig. 3, the left clamp 1 includes a screw 11 and a left positioning block 12. The screw 11 extends in the X direction, and the left positioning block 12 is fixedly connected to one end of the screw 11 and extends in a direction perpendicular to the extending direction of the screw. The screw is of a longitudinal structure, and a section cut along a plane perpendicular to a long axis of the screw has a concave shape. The concave shape is located on the surface of the screw 11 facing the left positioning block 12.

Specifically, the screw 11 includes a flight region 111 and a no-flight region 112. The surface of the threaded region 111 is threaded, and the surface of the unthreaded region 112 is a smooth surface. The cross section of the screw 11 in the direction A-A is in the shape of a crescent as shown in figure 4. The cross section of the threaded region 111 is an arc of a circle with a center O, which is a point through which the central axis B of the screw 111 passes. The cross section of the non-textured area 112 is an arc concave inward toward the center O, in other words, the concave shape is in the non-textured area.

The left positioning block 12 extends in a direction perpendicular to the screw 11 as a whole, and includes a left positioning column 121 and a left positioning head 122. The left positioning column 121 is fixedly connected with one end of the screw 11 and extends in a direction perpendicular to the screw 11. The first thickness H1 of the left positioning column 121 in the X direction is smaller than the second thickness H2 of the Zuo Ding bit head in the X direction. The left positioning block 12 further comprises a left positioning support plate 13, and two adjacent side edges of the positioning support plate 13 are fixedly connected with the screw 11 and the left positioning block 12 respectively and used for supporting the left positioning block 12 so as to improve the stress intensity of the left clamp 1.

As shown in fig. 5, the right clamp 2 includes a sleeve 21, a first positioning block 22, and a second positioning block 23. The sleeve 21 is a hollow cylinder and extends in the X direction. The inner wall of the sleeve 21 includes a circular arc-shaped inner wall 211 and a planar inner wall 212. The first positioning block 22 is fixedly connected to an outer wall corresponding to the planar inner wall 212 of the sleeve 21, which is located near one end in the X direction of the sleeve 21, and the first positioning block 22 extends in the Y direction perpendicular to the X direction. The first positioning block 22 includes a first positioning column 221 and a first positioning head 222, the first positioning column 221 is fixedly connected with the sleeve 21 and extends in the Y direction, and the first positioning head 222 is fixedly connected with an end of the first positioning column 221 remote from the sleeve 21. The first positioning head 222 is a cylinder. And, the third thickness H3 of the first positioning column in the X direction is smaller than the fourth thickness H4 of the first positioning head 222 in the X direction. The second positioning block 23 is fixedly connected to an outer wall corresponding to the planar inner wall 212, which is located near the other end of the sleeve 21 in the X direction and extends in the Y direction perpendicular to the X direction. The second positioning block 23 includes a second positioning column 231 and a second positioning head 232, where the second positioning column 231 is fixedly connected with the sleeve 21 and extends along the Y direction, and the second positioning head 232 is fixedly connected with one end of the second positioning column 231 away from the sleeve 21. That is, the first positioning head 222 and the second positioning head 232 each extend in the Y direction and then extend in opposite directions. In the embodiment of the present utility model, the second positioning block 23 has the same structure as the left positioning block 12 described above, and will not be described herein. In addition, the template chuck 100 provided by the present utility model may further include a middle support plate 24. One side of the middle supporting plate 24 is fixedly connected with the first positioning block 22, the other side is fixedly connected with the second positioning block 23, and the one side and the other side of the middle supporting plate 24 are opposite sides. The middle supporting plate 24 is used for supporting the first positioning block 22 and the second positioning block 23, so that the stress intensity of the right clamp 2 is improved.

As shown in fig. 6, the hammer nut 3 includes a nut 31 and a hammer post 32. The nut 31 is a hollow cylinder, the inner wall of which is provided with threads matching the threaded region 111 and extends in the X direction. The hammering post 32 is fixedly attached to the outer wall of the nut 31, and extends in the Y direction perpendicular to the X direction. In the embodiment of the present utility model, 2 hammer posts 32 are provided, and the 2 hammer posts 32 are symmetrically arranged with respect to the center axis of the nut 31 in the X direction as a symmetry axis. In addition, the number of hammer columns 32 may be arbitrarily set according to the actual situation.

The left clamp 1, the right clamp 2 and the hammering nut 3 are connected in the following manner: as shown in fig. 2, one end of the sleeve 21 of the right clamp 2 along the X direction is sleeved on the screw 11 of the left clamp 1, so that the left positioning block 12 of the left clamp 1 and the second positioning block 23 of the right clamp 2 are oppositely arranged at a preset distance. Since the inner wall of the sleeve 21 includes the circular arc-shaped inner wall 211 and the planar inner wall 212, the screw 11 and the sleeve 21 are brought into surface contact by the planar inner wall 212, increasing friction between the screw 11 and the sleeve 21, preventing the right clamp 2 from being unable to rotate about the left clamp 1. As shown in fig. 7, the sleeve 21 may also be fitted over the screw 11 of the left clamp 1 at the other end in the X direction such that the left positioning block 12 of the left clamp 1 and the first positioning block 22 of the right clamp 2 are disposed opposite to each other with a predetermined distance therebetween. The nut 31 of the hammer nut 3 is screwed onto the screw 11 and abuts against the sleeve 21 of the right clamp 2, fixing the position of the right clamp 2 on the screw 11. Since the cross section of the screw 11 is in a shape of a moon, that is, the cross section of the non-line area 112 is in an arc shape concave toward the center O, when the nut 31 is screwed into the screw 11, a gap is left between the inner wall of the nut 31 and the non-line area 112 of the screw 11, and the concrete remaining on the inner wall of the screw 11 and the nut 31 falls down in the screwing process, and can be removed through the gap, thereby ensuring the normal rotation of the hammering nut 3.

Next, the principle of fixing the tool type form 200 and the bulk wood form 300 by the form clamp 100 as shown in fig. 8 will be described by taking the form clamp as an example as shown in fig. 7. The first positioning head 222 of the right clamp 2 is inserted into the connecting hole on the frame 201 of the tool type template 200. Since the third thickness H3 of the first positioning post 221 along the X direction is smaller than the fourth thickness H4 of the first positioning head 222 along the X direction, the first positioning post 221 may abut against the frame 201 of the tool type template 200 when the first positioning head 222 is inserted into the connection hole on the frame 201 of the tool type template 200. The left positioning head 122 of the left clamp 1 is clamped to the positioning steel plate 302 of the frame 301 of the bulk wood form 300. Since the first thickness H1 of the left positioning post 121 in the X direction is smaller than the second thickness H2 of the left positioning head 122 in the X direction, the positioning steel plate 302 of the frame 301 of the bulk wood form 300 is just embedded in the space between the left positioning post 121 and the left positioning head 122. The hammering nut 3 is rotated again, so that the hammering nut 3 pushes the right clamp 2 to slide towards the left clamp 1 until the left clamp 1 and the right clamp 2 clamp the frame 201 of the tool type template 200 and the frame 301 of the bulk wood template 300.

When the form clamp 100 is of the construction shown in fig. 2, two bulk wood forms 300 as shown in fig. 9 may be fixedly connected. The second positioning head 222 of the right clamp 2 is clamped to the positioning steel plate of the frame 301 of the right bulk wood form 300. The left positioning head 122 of the left clamp 2 is clamped on the positioning steel plate of the frame 301 of the left bulk wood template 300. Since the second positioning head 222 and the left positioning head 122 have the same structure and operation principle, the description thereof will not be repeated here. The hammering nut 3 is rotated again, so that the hammering nut 3 pushes the right clamp 2 to slide towards the left clamp 1 until the left clamp 1 and the right clamp 2 clamp the rims 301 of the two bulk wood templates 300.

The nut 31 of the hammer nut 3 is screwed onto the screw 11 'and abuts against the sleeve 21 of the right clamp 2, fixing the position of the right clamp 2 on the screw 11'.

Next, a principle of fixing two tool templates 200 by using the template jig 100 as shown in fig. 12 will be described by taking the template jig 100 as shown in fig. 11 as an example. There may be small and temporary changes in the first floor, basement, etc. variable floor concrete structure, at which time splice battens 400 may be added between the two tool templates 200 to accommodate the changes. The first positioning head of the first positioning block 22 of the right clamp 2 is inserted into the connection hole on the frame of the right tool type template 200. The left positioning head clamp of the left positioning block 12 'of the left clamp 1' is inserted into the connecting hole on the frame of the left tool type template 200. The hammering nut 3 is rotated again so that the hammering nut 3 pushes the right clamp 2 to slide in the direction of the left clamp 1 'until the left clamp 1' and the right clamp 2 clamp the rims 201 of the two tool templates 200.
