Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an arc-shaped template positioning bender. Background Art

[0002] With the trend toward artistic architectural design, the pursuit of curvaceous beauty and natural forms has become fashionable. Consequently, architectural exteriors are becoming increasingly diverse, and architectural products that utilize curvilinear elements in their design are also becoming increasingly diverse. Currently, to achieve the curvilinear shapes of architectural products, custom molds or multiple small formworks are often used to support the formwork before concrete pouring. These formworks are then secured with reinforcements before the concrete is poured.

[0003] However, custom-made special molds are often expensive, and different shapes need to be customized again, which not only wastes materials but also has high construction costs; when using multiple small templates to splice, due to the large number of small templates, it is difficult to reinforce the formwork when supporting it through the small templates, and in the later pouring process, it is easy to have mold running, mold expansion and other phenomena, resulting in the need for repairs in the later stage, wasting labor and extending the construction period. Summary of the Invention

[0004] The purpose of this utility model is to provide an arc template positioning bender, which aims to solve the problems in general technology of wasting materials and high construction costs when customizing special molds to achieve product curve shaping, and the inconvenience of splicing and reinforcing small templates and requiring manual maintenance in the later stage.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: the arc-shaped template positioning bender comprises a bending plate, and a clip is slidably provided at both ends of the length of the bending plate, and the clip is used to clamp the template. A screw is rotatably installed in the middle of the bending plate, and a mounting plate is rotatably installed on the screw. The length direction of the mounting plate is parallel to the bending plate, and a pull rod is rotatably installed at both ends of the length direction of the mounting plate. The end of the pull rod is away from the mounting plate and is rotatably connected to the clip on the same side. The rotation of the screw drives the mounting plate to rise, and the clip is pulled longitudinally by the pull rod connected to the mounting plate to bend the template.

[0006] The beneficial effect is: by rotating the screw, the mounting plate slides along the height direction of the screw, and the mounting plate slides along the screw toward or away from the bending plate, and the mounting plate transmits force to the clamping part through the pull rod, so that the clamping part moves toward the middle of the bending plate or toward the two ends of the length direction of the bending plate under the action of the pull rod. When the clamping block moves to a certain position, the clamping part moves toward or away from the mounting plate under the action of the pull rod, thereby causing the bending plate and the template to bend and deform, so that when an arc-shaped template is needed for formwork, it does not need to be customized according to the product, thereby reducing construction costs. At the same time, the template is bent by a bender instead of splicing multiple small templates, reducing the inconvenience of small template construction and reinforcement, reducing the number of splicing seams generated after formwork, and reducing the probability of manual repair at the splicing seams due to mold running and mold expansion.

[0007] A further technical solution of the present invention is that a plurality of scales are evenly arranged on the surface of the bending plate.

[0008] The beneficial effect is: by setting scales on the surface of the bending plate, it is convenient for workers to adjust the sliding amount of the installation plate and the sliding amount of the clamping parts according to the required bending curvature to achieve precise bending of the template, so that the bending curvature of the template is closer to the actual needs of construction.

[0009] A further technical solution of the present invention is that both ends of the pull rod in the length direction are detachably connected to the mounting plate and the clamping piece.

[0010] The beneficial effect is that the pull rod can be replaced with different lengths through the detachable connection of the pull rod, so that the bender is suitable for templates of different sizes, thereby improving the application range of the bender.

[0011] A further technical solution of the present invention is that the clamping member includes a clamping block, the clamping block is provided with a clamping groove, and the clamping groove is used for clamping the bent plate.

[0012] The beneficial effect is that the bending plate is clamped by the clamping groove so that the bending plate is clamped and positioned by the clamping groove, so that the bender can efficiently and accurately achieve bending and positioning of the bending plate.

[0013] A further technical solution of the present invention is that the clamping member further includes two clamping rods installed along the height direction of the clamping block, the clamping rods are installed at both ends of the clamping groove in the height direction, and the clamping rods are detachably connected to the clamping block.

[0014] The beneficial effect is that the detachable connection between the clamping rod and the clamping block facilitates the maintenance and replacement of the clamping rod, and at the same time, the existence of the clamping rod further enhances the clamping of the clamping block to the template, thereby improving the stability of the template during the bending process.

[0015] A further technical solution of the present invention is that an abutment assembly is connected to the middle end of the bending plate facing away from the screw, and the abutment assembly includes a reinforcing plate fixedly connected to the bending plate and a number of elastic parts installed on the reinforcing plate, one end of the several elastic parts in the length direction is fixedly connected to the reinforcing plate, and the end of the elastic part facing away from the reinforcing plate abuts against the template.

[0016] The beneficial effects are: the strength of the middle part of the bending plate is improved by setting the reinforcing plate, the stability of the template during the bending process is improved by the elastic member abutting the template, and the probability of displacement of the template during the bending process is reduced.

[0017] A further technical solution of the present invention is that one end of the plurality of elastic members facing away from the reinforcing plate is fixedly connected to a wedge plate.

[0018] The beneficial effects are: the provision of the wedge-shaped plate enables the elastic force of the elastic member to act more evenly on the template; and at the same time, the provision of the wedge-shaped plate also facilitates the installation and positioning of the template.

[0019] A further technical solution of the present invention is that a handle is fixedly connected to one end of the lead screw away from the bending plate.

[0020] The beneficial effect is that the setting of the handle makes it easier for workers to rotate the lead screw, thereby improving the bending efficiency of the template. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-5 The specific implementation methods of the present utility model are further described.

[0028] The embodiment of the present application discloses an arc-shaped template positioning bender.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, an arc template positioning bender includes a bending plate 1. Since the bending plate 1 needs to be bent and in order for the bending plate 1 to be able to recover after bending, in this embodiment, the bending plate 1 uses a high-strength flexible steel plate. The high-strength flexible steel plate is a steel material with high strength and high toughness, which can withstand large stress, is not prone to brittle fracture, and has good plasticity. It can withstand multiple repeated deformations without breaking, thereby improving the service life of the bender; clamping parts 2 are slidably installed at both ends of the length direction of the bending plate 1, and the clamping parts 2 are used to clamp the template 0. The clamping parts 2 slide along the length direction of the bending plate 1, and a screw 3 is rotatably installed in the middle of the bending plate 1. A handle 10 is fixedly welded at the end of the screw 3 away from the bending plate 1, and a mounting plate 4 is rotatably installed on the screw 3. A thread is provided in the center of the mounting plate 4, and the mounting plate 4 is rotatably connected to the screw 3 through the thread, and the mounting plate 4 slides along the height direction of the screw 3. When the template 0 needs to be bent, the staff rotates the handle 10 to rotate the screw 3, and the screw 3 rotates to drive the mounting plate 4 to move along the height direction of the screw 3, and the angle between the pull rod 5 and the mounting plate 4 changes. When the clamping part 2 moves to a certain position, the angle between the pull rod 5 and the mounting plate 4 no longer changes. Under the action of the pull rod 5, the clamping part 2 moves toward or away from the mounting plate 4, thereby causing the bending plate 1 to bend, and the template 0 clamped by the clamping part 2 also bends accordingly, realizing the bending of the template 0, reducing the cost of customization when the template 0 needs to be bent, and at the same time eliminating the need for splicing through small templates 0, reducing the number of splicing seams, thereby improving construction quality, and reducing the labor cost generated by later maintenance.

[0031] Reference Figure 1 A number of scales 6 are evenly arranged on the surface of the bending plate 1. The scales 6 are arranged from the center of the bending plate 1 toward both ends of the length direction of the bending plate 1, which is convenient for the staff to position and install the clamping part 2. At the same time, when the staff calculates the movement amount of the installation plate 4 and the movement amount of the clamping part 2 according to the bending arc of the template 0, the bending angle of the template 0 is more accurate and closer to the actual needs.

[0032] Reference Figure 1 and Figure 2The clamping member 2 includes a clamping block 21 and two clamping rods 22 detachably connected to the clamping block 21. A clamping groove 7 is opened on the clamping block 21, and the clamping rods 22 are installed at both ends of the clamping groove 7 in the height direction. In this embodiment, the bending plate 1 is installed in the clamping groove 7 and the size of the clamping groove 7 matches the size of the bending plate 1. The template 0 is installed between the two clamping rods 22. When the screw 3 is rotated, the mounting plate 4 moves along the height direction of the screw 3. The mounting plate 4 causes the clamping block 21 to slide along the length direction of the bending plate 1 through the pull rod 5. When the pull rod 5 forms a certain angle and the mounting plate 4 continues to move, the clamping block 21 moves toward or away from the mounting plate 4, and the bending plate 1 bends and the template 0 bends at the same time.

[0033] Reference Figure 1 The clamping rod 22 is detachably connected to the clamping block 21 through a thread, which makes it easy to replace the clamping rods 22 of different lengths according to the length of the template 0 to achieve better clamping and limiting of the template 0; in this embodiment, the shape of the clamping rod 22 is rectangular. When the template 0 is large in size and the bending angle is not large, the clamping rod 22 clamps the template 0. The use of a rectangular shape for the clamping rod 22 makes the clamping rod 22 and the template 0 in surface contact, so that the clamping rod 22 has a better effect of clamping and limiting the template 0, thereby making the bending effect of the template 0 better.

[0034] Reference Figure 2 and Figure 4 , an abutment assembly 8 is fixedly installed at one end of the middle part of the bending plate 1 away from the lead screw 3, and the abutment assembly 8 includes a reinforcing plate 81 fixedly connected to the bending plate 1 and a plurality of elastic members 82 installed in the reinforcing plate 81, one end of the elastic member 82 in the length direction is fixedly connected to the reinforcing plate 81, and the end of the elastic member 82 away from the reinforcing plate 81 abuts against the template 0, and the elastic member 82 abuts against the template 0 to reinforce the position of the template 0, thereby reducing the influence of the displacement of the template 0 on the bending effect during the bending process; in this embodiment, the reinforcing plate 81 is a rectangular steel plate, which increases the strength of the middle part of the bending plate 1; the reinforcing plate 81 is provided with a mounting groove 11, and a number of elastic members 82 are installed along the length direction of the mounting groove 11. In this embodiment, the elastic member 82 is a spring, one end of the spring is fixedly connected to the bottom of the mounting groove 11, and the end of the spring facing away from the mounting groove 11 is fixedly connected to a wedge plate 9. When the template 0 is installed toward the clamping rod 22, the wedge plate 9 abuts against the wedge plate 9 so that the wedge plate 9 squeezes the spring to slide toward the bottom of the mounting groove 11. Under the elastic force of the spring, the wedge plate 9 reinforces the template 0, so that the point contact between the spring and the template 0 is changed to surface contact, thereby enhancing the reinforcing effect of the elastic member 82 on the template 0.

[0035] Reference Figure 2 and Figure 3The mounting plate 4 and the clamping block 21 are both fixedly installed with two relatively arranged fixing plates 12 at the installation position of the pull rod 5. The pull rod 5 is installed between the two relatively installed fixing plates 12. A pin 13 is passed through the pull rod 5 and the fixing rod. The pin 13 passes through the pull rod 5 and the fixing plate 12. An anti-trip buckle 14 is installed at one end of the pin 13 in the length direction. The anti-trip buckle 14 is used to prevent the pin 13 from falling off, so that the connection between the pull rod 5 and the fixing plate 12 is more stable; at the same time, the setting of the pin 13 and the anti-trip buckle 14 also facilitates the pull rod 5 to be replaced according to the actual size of the bending template 0, so that the bender can adapt to more templates 0 of different sizes.

[0036] The implementation principle of this embodiment is as follows: before bending the template 0, the appropriate pull rod 5 and the clamping rod 22 are replaced according to the size of the bent template 0, and the sliding distance of the mounting block and the sliding distance of the clamping block along the bending plate 1 are calculated according to the bending angle of the template 0; after the above preparations are completed, the template 0 is clamped in the clamping groove 7 and the upper and lower end faces of the template 0 respectively abut against the clamping rod 22, the bottom of the template 0 abuts against the wedge plate 9 and the connection between the template 0 and the wedge plate 9 is fixed under the elastic force of the spring; turn the handle 10, when the mounting plate 4 moves away from the bending plate 1 along the height direction of the screw 3, the clamping part 2 moves toward the screw, and after the pull rod 5 forms a certain angle but the mounting plate 4 continues to move, the clamping block 21 moves toward the mounting plate 4 under the action of the pull rod 5. When the cam 10 is turned, the bending plate 1 and the template 0 are bent. When the required curvature is reached, stop turning the handle 10 to keep the bent state. When the corresponding time is reached, pull out the template 0 to bend the next template 0. When the mounting plate 4 moves along the height direction of the lead screw 3 toward the bending plate 1, the clamping part 2 moves toward both ends of the length direction of the bending plate 1. After the pull rod 5 forms a certain angle but the mounting plate 4 continues to move, the clamping block 21 moves away from the mounting plate 4 under the action of the pull rod 5, and the bending plate 1 and the template 0 are bent. When the required curvature is reached, stop turning the handle 10 to bend the template 0, so that the template 0 and the bender maintain this state. When the corresponding bending time is reached, pull out the template 0, and wait for the bending plate 1 to recover before bending the next template 0.

[0037] Example 2:

[0038] Reference Figure 5 The difference between Example 2 and Example 1 is that the shape of the clamping rod 22 is cylindrical. When the size of the template 0 is small and the bending angle is large, the clamping rod 22 uses a cylindrical shape so that the contact between the clamping rod 22 and the template 0 is a linear connection, reducing the influence of the clamping rod 22 on the bending of the template 0 during the bending process, facilitating the bending of the template 0, and improving the bending effect of the template 0.

[0039] The implementation principle of Example 2 is that before bending the template 0, the appropriate pull rod 5 and the clamping rod 22 are replaced according to the size of the bent template 0, and the sliding distance of the mounting block and the sliding distance of the clamping block along the bending plate 1 are calculated according to the bending angle of the template 0; after the above preparations are completed, the template 0 is clamped in the clamping groove 7 and the upper and lower end faces of the template 0 respectively abut against the clamping rod 22, the bottom of the template 0 abuts against the wedge plate 9 and the connection between the template 0 and the wedge plate 9 is fixed under the elastic force of the spring; turn the handle 10, when the mounting plate 4 moves away from the bending plate 1 along the height direction of the screw 3, the clamping part 2 moves toward the screw, and after the pull rod 5 forms a certain angle but the mounting plate 4 continues to move, the clamping block 21 moves toward the mounting plate 4 under the action of the pull rod 5. When the cam 10 is turned, the bending plate 1 and the template 0 are bent. When the required curvature is reached, stop turning the handle 10 to keep the bent state. When the corresponding time is reached, pull out the template 0 to bend the next template 0. When the mounting plate 4 moves along the height direction of the lead screw 3 toward the bending plate 1, the clamping part 2 moves toward both ends of the length direction of the bending plate 1. After the pull rod 5 forms a certain angle but the mounting plate 4 continues to move, the clamping block 21 moves away from the mounting plate 4 under the action of the pull rod 5, and the bending plate 1 and the template 0 are bent. When the required curvature is reached, stop turning the handle 10 to bend the template 0, so that the template 0 and the bender maintain this state. When the corresponding bending time is reached, pull out the template 0, and wait for the bending plate 1 to recover before bending the next template 0.
