[0002] In the construction of many construction projects, templates are used in large quantities, including wooden templates. At the current stage, the construction of reserved holes at wellheads or openings usually uses multiple wooden templates to form the outline shape of the target hole, and uses square wood for support. Regardless of whether the reserved holes at the wellhead or opening at the construction site are round or square, the material needs to be further processed. The wooden template will go through the procedures of cutting, assembly, positioning, and support until the construction is completed and then removed one by one. Moreover, after the wooden template is used at a certain position, it will be removed and transferred to the next position for reuse as much as possible, and then the above steps will be repeated. In the process of removing the wooden template, cement bonding templates are often encountered. It is not difficult to find that traditional wooden templates have obvious shortcomings in the construction of reserved holes at wellheads or openings. The overall construction process has many steps, the template installation is not convenient enough, and the template removal is difficult, which affects the construction speed; the frequent installation and removal of wooden templates greatly reduces its durability and has poor recycling efficiency.

[0024] Example 1

[0025] refer to Figure 1-Figure 5 The present embodiment provides a template for the construction of reserved holes in an opening, comprising a cylinder 1 and a support ring 2 for preventing the cylinder 1 from deforming, the support ring 2 being sleeved in the cylinder 1, and the cylinder 1 and the support ring 2 being detachably connected; the support ring 2 is provided with a connecting piece 21 and a support rod 22, and the support rod 22 is connected end to end through the connecting piece 21 to form a closed loop; the connecting piece 21 is movably connected to the support rod 22, and the connecting piece 21 rotates along a first direction, and the radius of the support ring 22 decreases, and the connecting piece 21 rotates along a second direction, and the radius of the support ring 22 increases.

[0026] Specifically, the cylinder 1 includes a raised portion 11. The raised portion 11 is provided on the inner wall of the cylinder 1 for contacting the support ring 2. The raised portion 11 is provided along the height direction of the cylinder 1, and the raised direction of the raised portion 11 is radially inward. Preferably, the raised portion 11 has a cross-sectional size of 40 mm×40 mm, a height of 25 mm, and a spacing of 100 mm between each row.

[0027] In order to ensure the supporting effect of the support ring 2 on the cylinder 1, the template for the construction of reserved holes for the opening further includes a bracket 3, which supports the support ring 2. The bracket 3 is arranged on the raised portion 11. In this embodiment, the number of the brackets 3 arranged on the raised portion 11 is 3. It can be understood that the number of the brackets 3 arranged on the raised portion 11 is at least 1. The bracket 3 includes a first wall 31 and a second wall 32. The size of the first wall 31 is 40mm×40mm, the size of the second wall 32 is 40mm×40mm, the thickness of both walls is 4mm, and both are made of 304 stainless steel. The raised portion 11 is reserved with screw holes every 50mm, and the first wall 31 of the bracket 3 is connected to the raised portion 11 through fasteners to cooperate with the screw holes. The first wall 31 and the second wall 32 are arranged at an angle, and the angle between the first wall 31 and the second wall 32 is used to place the support ring 2. The fastener is preferably an M4 screw.

[0028] The support ring 2 is provided with a connecting piece 21 and a support rod 22. The support ring 2 is sleeved in the cylinder 1, and the support ring 2 and the cylinder 1 are detachably connected. The support ring 2 is installed in the cylinder 1 to provide a radial outward support force to the cylinder 1. The support ring 2 firmly presses against the inside of the cylinder 1 to prevent the cylinder 1 from being severely deformed by external factors, such as concrete extrusion. In this embodiment, the support ring 2 includes two support rods 22. It can be understood that the support ring 2 includes at least one support rod 22. The support rod 22 is a 304 stainless steel square tube with a cross-sectional size of 40mm×40mm and a wall thickness of 4mm; the cross-section of the support rod 22 can also be circular. The support rods 22 are connected end to end through the connecting piece 21 to form a closed loop.

[0029] When the connecting member 21 is rotated clockwise, the radius of the support ring 2 is reduced; when the connecting member 21 is rotated counterclockwise, the radius of the support ring 2 is increased. Specifically, the connecting member 21 includes an operating portion 211 and a matching portion 212. The matching portion 212 is arranged on both sides of the operating portion 211, one end of the matching portion 212 is fixedly connected to the operating portion 211, and one end of the matching portion 212 away from the operating portion 211 is movably connected to the support rod 22. The operating portion 211 controls the rotation direction of the matching portion 212. The construction personnel can hold the operating portion 211 and rotate the matching portion 212 clockwise or counterclockwise to change the radius of the support ring 2, thereby further changing the supporting force generated by the support ring 2 on the cylinder 1. In detail, in this embodiment, when the operating portion 211 rotates clockwise, the radius of the support ring 2 decreases, and the support rods 22 on both sides of the connecting member 21 approach each other; when the operating portion 211 rotates counterclockwise, the radius of the support ring 2 increases, and the support rods 22 on both sides of the connecting member 21 move away from each other. In this embodiment, the matching portion 212 is a thread, and the thread directions of the two threads on both sides of the operating portion 211 are opposite.

[0030] The cylinder 1 is made of isoprene rubber. The cylinder 1 is 15 mm thick and 25 mm high. In this embodiment, the contour shape of the cylinder 1 is described by taking a circle as an example. It should be emphasized that the construction personnel can set the specific parameters of the shape of the cylinder 1 according to the shape and size of the reserved holes at the construction site. In this embodiment, the isoprene rubber material is elastic at room temperature, deformed by external force, and can return to its original state after the external force is removed. Therefore, this characteristic can be used to improve the problem of concrete cement slurry adhering to the template, and at the same time can increase the number of times the template is recycled. In detail, on the one hand, during the external concrete pouring process, an extrusion force will be applied to the outer wall of the cylinder 1, but due to the radial outward support force provided by the support ring 2 inside the cylinder 1, the support force is greater than the extrusion force; on the other hand, the cylinder 1 is made of isoprene rubber material, so during the external concrete pouring process, the cylinder 1 will produce slight deformation, but it will not affect the shape and size of the reserved holes at the final wellhead. After the concrete is poured and formed, the concrete cement slurry adhered to the outer wall of the cylinder 1 will automatically fall off, which is convenient for construction workers to remove the mold and reduces the difficulty of removing the mold. Secondly, it reduces the cleaning work of the construction workers on the template. After taking the template out from the reserved hole position, it is only necessary to simply knock the template to shake off the small amount of cement slurry remaining on the template. In short, the template made of isoprene rubber material can make the template have good wear resistance, heat resistance and chemical stability.

[0031] Furthermore, the use of the template is described in detail in this embodiment. The construction personnel arrange the cylinder 1 at the reserved hole position to be constructed, and assemble the bracket 3 on the raised portion 11 of the cylinder 1 according to the set spacing, and the number of brackets 3 on each raised portion 11 is the same. Then adjust the connecting member 21, rotate the connecting member 21 clockwise, and the radius of the support ring 2 is reduced, so that the support ring 2 can be smoothly placed in the cylinder 1 and placed on the angle formed by the first wall 31 and the second wall 32 of the bracket 3. At this time, it should be noted that in order to ensure that the support ring 2 supports the cylinder 1 well, the connecting member 21 should avoid the position of the bracket 3, and the support rod 22 should abut the bracket 3. After the support ring 2 is placed on the bracket 3, the connecting member 21 is rotated again, and the connecting member 21 is rotated counterclockwise, and the radius of the support ring 2 increases. The support ring 2 with an increased radius firmly supports the bracket 3, thereby generating a radial outward force on the cylinder 1 to squeeze the cylinder 1. In actual construction, the externally poured concrete will squeeze the outer wall of the cylinder 1, causing slight deformation of the cylinder 1, and the support force of the support ring 2 on the cylinder 1 can resist the above deformation. When there are multiple support rings 2 in the template, the support rings 2 are arranged and adjusted in order from bottom to top. After the external concrete is formed, the connecting piece 21 is rotated again, and the connecting piece 21 is rotated clockwise, the radius of the support ring 2 is reduced, and the support ring 2 is directly taken out from the cylinder 1. At this time, the cylinder 1 loses its support, and the cylinder 1 can be removed from the reserved hole construction position without much effort.

[0032] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
