DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please see attached Figure 1 and attached Figure 4 A construction template clamping device includes a clamping assembly, a positioning tube 7 and a support column 8; the clamping assembly is annular in structure, and several groups of clamping assemblies are vertically spaced and sleeved on the template, and several groups of clamping assemblies can abut against the outer wall of the template; the two ends of the support column 8 are vertically connected to the opposite sides of two adjacent groups of clamping assemblies through the positioning tube 7, and several support columns 8 are arranged at intervals along the circumference of the clamping assembly and surround the outer side of the mold.

[0026] A through groove structure is formed in the annular clamping assembly for the template to pass through, so that the clamping assembly can be sleeved and tightened on templates of different structures such as cylindrical and square columns to achieve the purpose of clamping the template. The positioning tube 7 can be pre-installed on the clamping assembly for plugging the support column 8, so that several groups of clamping assemblies can be connected into a whole through the support column 8, and several groups of clamping assemblies are coaxially arranged, which is convenient for more stable and reliable clamping of the template.

[0027] Preferably, two groups of clamping assemblies can be used, and the number of clamping assemblies can also be adjusted according to the actual height adaptability of the template. The height of the support column 8 can be selected according to the actual height adaptability of the template, so that the two groups of clamping assemblies can be clamped at the upper 1 / 3 and lower 1 / 3 of the template, or the clamping assemblies can be clamped at the concentrated force position of the template.

[0028] Please see attached Figure 1 To Attachment Figure 4 Each group of the clamping components includes a U-shaped groove plate 1, a two-way driving mechanism 2, a clamping mechanism 3 and a side supporting mechanism 5; the U-shaped groove plate 1 is a U-shaped structure with one end open, and a plurality of supporting columns 8 are respectively connected to the corners of the U-shaped groove plate 1 through positioning tubes 7; the side supporting mechanism 5 is movably arranged at the open end of the U-shaped groove plate 1 and can abut against the outer side wall of the template, and the two-way driving mechanism 2 is embedded in the closed end of the U-shaped groove plate 1; a pair of clamping mechanisms 3 are respectively movably connected to the two-way driving mechanism 2, so that a pair of clamping mechanisms 3 are symmetrically arranged in the U-shaped groove plate 1 and can abut against the templates at both ends of the mold.

[0029] Preferably, the U-shaped groove plate 1 can adopt a rectangular structure surrounded by three sides, a U-shaped groove is formed inside the rectangular structure, and the size of the U-shaped groove plate 1 can be adaptively adjusted according to the size of the template. Positioning tubes 7 are set at the four corners of the rectangular structure.

[0030] The bidirectional driving mechanism 2 is used to drive the pair of clamping mechanisms 3 to move away from or towards each other, so that the pair of clamping mechanisms 3 can effectively clamp and fix templates of different sizes. The pair of clamping mechanisms 3 are symmetrically arranged, and the side support mechanism 5 is located at the open end of the U-shaped groove plate 1 on the side of the pair of clamping mechanisms 3, so that the template is clamped on three sides by the pair of clamping mechanisms 3 and the side support mechanism 5, thereby improving the stability of clamping.

[0031] Please see attached Figure 2 The bidirectional driving mechanism 2 includes a bidirectional screw 21, a driving block 22, a rotary head 23 and a rotary handle 24; both ends of the bidirectional screw 21 are rotatably arranged in the closed end of the U-shaped groove plate 1 through a rotating bearing, a pair of driving blocks 22 are screwed on the bidirectional screw 21 through a threaded rotation sleeve, and a pair of clamping mechanisms 3 are fixedly connected to the pair of driving blocks 22 respectively; one end of the rotary head 23 is coaxially fixedly connected to one end of the bidirectional screw 21, and the other end of the rotary head 23 passes through the outside of the side wall of the U-shaped groove plate 1 and is coaxially fixedly connected to the rotary handle 24.

[0032] The bidirectional screw 21 is provided with two sections of threads in opposite directions, and a threaded through hole is provided in the driving block 22. When the bidirectional screw 21 rotates, the threaded sections drive the driving block 22 to make a linear motion along the axial direction of the bidirectional screw 21 through the threaded through hole. Since the directions of the two sections of threads are opposite, the movement directions of the pair of driving blocks 22 are opposite, thereby driving the pair of clamping mechanisms 3 to move away from or towards each other.

[0033] Preferably, a slide groove is provided at the closed end of the U-shaped groove plate 1, and the ends of a pair of drive blocks 22 are slidably embedded in the slide groove, so that the pair of drive blocks 22 can only make linear motion along the axial direction of the bidirectional screw rod 21 under threaded drive, and will not rotate synchronously with the bidirectional screw rod 21, thereby ensuring the effective driving of a pair of clamping mechanisms 3.

[0034] The rotary head 23 extends outwardly to the outside of the U-shaped groove plate 1 and is provided with a rotary handle 24. The edge of the rotary handle 24 can be set to be wavy, which is convenient for holding and rotating the rotary head 23, thereby driving the bidirectional screw rod 21 to rotate, and the operation is convenient.

[0035] Please see attached Figure 2 and attached Figure 3 The screw head 23 is formed with an inner hexagonal groove (not shown in the figure), and an outer hexagonal wrench can be matched and inserted into the inner hexagonal groove.

[0036] The external hexagonal wrench is inserted into the internal hexagonal slot, and the external hexagonal wrench can be used to drive the screw head 23 to rotate, thereby easily, labor-savingly and efficiently driving the bidirectional screw rod 21 to rotate.

[0037] Please see attached Figure 2 and attached Figure 3 Each group of the clamping mechanisms 3 includes a clamping plate 31 and a clamping strip 32; one end of the clamping plate 31 is fixedly connected to the driving block 22, a pair of clamping strips 32 are symmetrically arranged at both ends of the clamping plate 31, a pair of clamping strips 32 and one surface of the clamping plate 31 form a U-shaped structure of the clamping template, and a guide mechanism 4 is provided between the other surface of the clamping plate 31 and the side wall of the U-shaped groove plate 1.

[0038] The clamping plate 31 can be attached to and pressed against the end of the template, and a pair of symmetrically arranged clamping mechanisms 3 can symmetrically clamp and fix the two ends of the template through the clamping plate 31, thereby improving the template clamping stability and convenience. At the same time, a pair of pressing strips 32 can assist in pressing against the end of the template and provide lateral limit to the template, further ensuring the clamping stability of the template.

[0039] Please see attached Figure 2 and attached Figure 3 The pair of clamping strips 32 have one side opposite to the other forming a clamping slope 33 so that the clamping slope 33 can be pressed against the outer wall of the template.

[0040] For a cylindrical template, the clamping slope 33 can be used to improve the adaptability and fit to the cylindrical wall, thereby ensuring reliable clamping of the cylindrical template.

[0041] Please see attached Figure 2 and attached Figure 3The guide mechanism 4 includes a guide rod 41 and a limit ring 43. One end of the guide rod 41 is vertically connected to the center of the other surface of the clamping plate 31, and the other end of the guide rod 41 passes through the through hole reserved on the side wall of the U-shaped groove plate 1 and extends to the outside of the U-shaped groove plate 1; the limit ring 43 is arranged on the other end of the guide rod 41, and the outer diameter of the limit ring 43 is larger than the aperture of the through hole.

[0042] By setting the guide rod 41, the guide rod 41 moves horizontally along the through hole relative to the side wall of the U-shaped groove plate 1, which can improve the movement stability of the clamping plates 31 in the process of the clamping plates 31 approaching or moving away from each other. The limit ring 43 can prevent the distance between the pair of clamping plates 31 from being too close, causing the guide rod 41 to fall out of the through hole of the U-shaped groove plate 1.

[0043] Please see attached Figure 2 and attached Figure 3 The guide rod 41 is sleeved with a spring 42 , and the two ends of the spring 42 are respectively connected between the outer wall of the U-shaped groove plate 1 and the limiting ring 43 .

[0044] When the spring 42 is installed, within the travel range of the clamping plate 31, the spring 42 is always in a compression state to varying degrees, so that the elastic force of the spring 42 is used to form a thrust force on the clamping plate 31, thereby further improving the stability and reliability of the clamping of the template by a pair of clamping plates 31, and also improving the structural stability of the clamping mechanism 3 and the guide mechanism 4.

[0045] Please see attached Figure 2 and attached Figure 3 The inner walls of both sides of the U-shaped groove plate 1 are formed with sliding grooves (not shown in the figure), and the two ends of the side support mechanism 5 are respectively slidably embedded in the two sliding grooves and are tightly fixed by positioning bolts 6.

[0046] The side supporting mechanism 5 slides through the slide groove and can be used to clamp and fix templates of different sizes. The side outer wall of the template is pressed and fixed by the side supporting mechanism 5, so as to further improve the clamping stability of the template.

[0047] Please see attached Figure 2 and attached Figure 3 The side support mechanism 5 includes an arc plate 51 and an end block 52. A pair of end blocks 52 are respectively arranged at both ends of the arc plate 51. A pair of end blocks 52 are respectively slidably arranged in two slide grooves so that the convex part of the arc plate 51 abuts against the outer wall of the template.

[0048] Preferably, the arc plate 51 can adopt an arc plate structure such as a thin steel plate with certain elastic properties, which can be pressed against the side outer wall of the template. The arc structure and deformation of the arc plate 51 can ensure effective clamping effect and adaptability to templates of different sizes.

[0049] The size of the end block 52 is adaptively adjusted according to the size of the slide groove to ensure that the position of the arc plate 51 can be slidably adjusted according to the size of the template, and the convex part of the arc plate 51 abuts against the outer wall of the template.

[0050] Preferably, screw holes matching the positioning bolts 6 are provided at both ends of the U-shaped slot plate 1, and the ends of the positioning bolts 6 are screwed into the U-shaped slot plate 1 through the screw holes and tightened against the end block 52, thereby tightening the end block 52 to the inner wall of the slide groove, thereby fixing the arc plate 51 and abutting against the outer wall of the template.

[0051] Please see attached Figure 1 To Attachment Figure 4 , the usage method and working principle of the utility model are:

[0052] The utility model can be made of steel material with high structural strength as a whole, so as to ensure the clamping effect, be not easy to deform and damage, and have a long service life.

[0053] Select support columns 8 of corresponding length according to the height of the template, fix the support columns 8 between a pair of U-shaped groove plates 1 through positioning tubes 7, and sleeve the pair of U-shaped groove plates 1 on the upper and lower parts of the template respectively.

[0054] The screw head 23 is rotated by the handle 24 or the hexagonal wrench to drive the two-way screw 21 to rotate, and the two threads of the two-way screw 21 respectively drive a pair of driving blocks 22 to move closer to each other along the axial direction of the two-way screw 21. The pair of driving blocks 22 drives a pair of clamping mechanisms 3 to move closer to each other synchronously, so that one surface of the clamping plate 31 can fit tightly against the outer wall of the template.

[0055] The two end blocks 52 are slid along the two slide grooves to drive the arc plate 51 to move toward the side wall of the template, so that the convex part of the arc plate 51 is pressed and fixed on the outer wall of the template, thereby clamping the template in three directions to ensure the clamping stability of the template and the convenience of disassembly and assembly.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
