Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of difficulty in adjusting the relative positions of the inner mold 300 and the outer mold 100, this utility model provides a hollow bridge pier template that can adjust the relative positions of the inner mold 300 and the outer mold 100 to correct errors in the inner mold 300 and the outer mold 100, thereby ensuring the accuracy of the hollow bridge pier production.

[0020] It should be noted that the hollow pier formwork described in this utility model is used for the casting of hollow piers. For ease of explanation, this utility model will be described in terms of the hollow pier formwork being used for the casting of hollow piers.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a hollow bridge pier template in one embodiment of the present invention. The hollow bridge pier template includes an outer mold 100, an adjustment component 200, and an inner mold 300. The outer mold 100 has a receiving cavity with an opening at the top. The adjustment component 200 includes a first support 210 and a second support 220. The first support 210 is slidably disposed at the top of the outer mold 100 and can stop at any position on its sliding trajectory. The second support 220 is slidably disposed on the first support 210 and can stop at any position on its sliding trajectory. The sliding directions of the second support 220 and the first support 210 have an angle. One end of the inner mold 300 is installed on the second support 220, and the other end extends into the receiving cavity to form a casting area between the outer wall of the inner mold 300 and the inner wall of the outer mold 100.

[0022] First, the inner mold 300 is extended into the receiving cavity, forming a pouring area between the outer wall of the inner mold 300 and the inner wall of the outer mold 100. Then, the inner mold 300 is moved by sliding the first support 210 and the second support 220, thereby adjusting the relative position between the inner mold 300 and the outer mold 100. After the position adjustment of the inner mold 300 and the outer mold 100 is completed, the first support 210 and the second support 220 can be fixed, thereby fixing the inner mold 300. Concrete can then be poured into the pouring area. Using the hollow pier formwork provided by this invention, the relative position of the inner mold 300 and the outer mold 100 can be adjusted to correct errors in the inner mold 300 and the outer mold 100, ensuring the accuracy of the hollow pier production.

[0023] In some embodiments, the adjustment assembly 200 further includes a first limiting member 230, which is mounted on the first bracket 210. The first limiting member 230 has a first state of connecting to the outer mold 100 to prevent the first bracket 210 from moving relative to the outer mold 100, and a second state of disengaging from the outer mold 100 to allow the first bracket 210 to move relative to the outer mold 100. When it is necessary to adjust the position of the first bracket 210, the first limiting member 230 can be switched to the second state first, at which point the position of the first bracket 210 can be adjusted. Once the first bracket 210 is adjusted to a suitable position, the first limiting member 230 can be switched to the first state, thereby fixing the position of the first bracket 210.

[0024] Based on the above embodiments, in some embodiments, the first support 210 has a plurality of first screw holes 211, and the first limiting member 230 includes a plurality of first bolts 231 corresponding one-to-one with the plurality of first screw holes 211. The first bolts 231 are screwed into the first screw holes 211, so that the first bolts 231 press against or disengage from the outer mold 100, thereby allowing the first limiting member 230 to switch between a first state and a second state. The first bolts 231 are screwed into the first screw holes 211, and the position of the first bolts 231 within the first screw holes 211 can be adjusted by rotating the first bolts 231. When the first bolts 231 press against the outer mold 100, the friction between the first bolts 231 and the outer mold 100 can prevent the first support 210 from moving relative to the outer mold 100. When the first bolts 231 disengage from the outer mold 100, the friction between the first bolts 231 and the outer mold 100 is lost, and the first support 210 can move relative to the outer mold 100.

[0025] In some embodiments, the adjustment component 200 includes a second limiting member 240, which is mounted on the second bracket 220. The second limiting member 240 has a third state in which it is connected to the first bracket 210 to prevent the second bracket 220 from moving relative to the first bracket 210, and a fourth state in which it is disengaged from the first bracket 210 to allow the second bracket 220 to move relative to the first bracket 210. When it is necessary to adjust the position of the second bracket 220, the second limiting member 240 can be switched to the fourth state, at which point the position of the second bracket 220 can be adjusted. After the second bracket 220 is adjusted to a suitable position, the second limiting member 240 can be switched to the third state, thereby fixing the position of the second bracket 220.

[0026] Based on the above embodiments, in some embodiments, the second bracket 220 has a plurality of second screw holes 221, and the second limiting member 240 includes a plurality of second bolts 241 corresponding one-to-one with the plurality of second screw holes 221. The second bolts 241 are screwed into the second screw holes 221, causing the first bolt 231 to press against or disengage from the outer mold 100, so that the first limiting member 230 switches between a first state and a second state. The second bolts 241 are screwed into the second screw holes 221, and the position of the second bolts 241 in the second screw holes 221 can be adjusted by rotating the second bolts 241. When the second bolts 241 press against the first bracket 210, the friction between the second bolts 241 and the first bracket 210 can prevent the second bracket 220 from moving relative to the first bracket 210. When the second bolts 241 disengage from the first bracket 210, the friction between the second bolts 241 and the first bracket 210 is lost, and the second bracket 220 can move relative to the outer mold 100.

[0027] In some embodiments, the inner mold 300 includes a base column 310 and a plurality of inner side plates 320. One end of the base column 310 is mounted on the second bracket 220, and the other end extends into the receiving cavity. The plurality of inner side plates 320 are arranged along the circumference of the base column 310 and connected to the base column 310, and the plurality of inner side plates 320 surround to form an inner forming surface.

[0028] Based on the above embodiments, in some embodiments, the inner mold 300 further includes a plurality of connectors 330 corresponding one-to-one with a plurality of inner side plates 320. One end of each connector 330 is detachably connected to an inner side plate 320, and the other end is detachably connected to a base column 310. The two ends of the connector 330 are detachably connected to the base column 310 and the inner side plate 320 respectively, thereby fixing the relative position of the inner side plate 320 and the base column 310, thus forming an inner molding surface by splicing together the various inner side plates 320. When it is necessary to demold the various inner side plates 320, the connectors 330 can be disassembled, thereby causing the inner side plates 320 to detach from the solidified concrete.

[0029] In some embodiments, the outer mold 100 includes a plurality of outer side plates 110, which are sequentially and detachably connected to enclose and form an outer molding surface. A casting area is enclosed between the outer molding surface and the inner molding surface. When it is necessary to demold each of the outer side plates 110, the connection between each of the outer side plates 110 can be released first, and then each outer side plate 110 can be detached from the solidified concrete one by one.

[0030] In some embodiments, the second bracket 220 has a mounting opening 222, through which the base column 310 partially passes. The end of the base column 310 has a pressing portion 311, the outer diameter of which is larger than the diameter of the mounting opening 222, to prevent the base column 310 from detaching from the mounting opening 222. The mounting opening 222 can limit the base column 310, thereby preventing it from moving radially relative to the second bracket 220. Since the end prevents the base column 310 from detaching from the mounting opening 222, it can restrict the base column 310's movement along the axis, thus fixing the position of the base column 310.

[0031] In some embodiments, a first guide rail 120 is laid on the top of the outer mold 100, a first bracket 210 is slidably disposed on the first guide rail 120, a second guide rail 212 is laid on the first bracket 210, and a second bracket 220 is slidably disposed on the second guide rail 212. Under the guidance of the first guide rail 120 and the second guide rail 212, the first bracket 210 and the second bracket 220 have a precise temperature sliding trajectory.

[0032] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: One end of the base column 310 is installed on the second bracket 220, and the other end extends into the receiving cavity. Several inner side plates 320 are arranged around the base column 310 and connected to the base column 310, and the several inner side plates 320 enclose to form an inner forming surface. Several outer side plates 110 are sequentially and detachably connected to enclose to form an outer forming surface, and a casting area is enclosed between the outer forming surface and the inner forming surface. Then, the first limiting member 230 is adjusted to the second state, and the second limiting member 240 is adjusted to the fourth state. By sliding the first bracket 210 and the second bracket 220, the inner mold 300 is moved, thereby adjusting the relative position between the inner mold 300 and the outer mold 100. After the position adjustment of the inner mold 300 and the outer mold 100 is completed, the first limiting member 230 is adjusted to the first state, and the second limiting member 240 is adjusted to the third state, thereby fixing the first bracket 210 and the second bracket 220, and thus fixing the inner mold 300. Concrete can then be poured in the casting area. The hollow bridge pier template provided by this utility model can be used to adjust the relative positions of the inner mold 300 and the outer mold 100, so as to correct the errors of the inner mold 300 and the outer mold 100 and ensure the accuracy of the hollow bridge pier production.
