[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-2As shown, the embodiment provides a bridge pier column template that is easy to assemble and disassemble, including a mold body 1 and a support mechanism 2. The mold body 1 has a slanted rectangular structure, and the support mechanism 2 is provided on one side of the mold body 1. The support mechanism 2 includes a support truss 201, a moving platform 202, a first support rod 203, a first support column 204, a rotating seat 205, a second support rod 206, a second support column 207, a sleeve 208, a lifting seat 209, a first lead screw 210, and a first motor 211. The support truss 201 is fixedly installed on the ground, and the moving platform 202 is provided on the support truss 201. The first support rod 203 is inclinedly provided on the moving platform 202, and the higher end of the first support rod 203 is hinged to a first support. The mold body 1 has a first support column 204, which is detachably connected to the mold body 1. A rotating seat 205 is provided above the first support rod 203 and is rotatably connected to the moving platform 202. A second support rod 206 is fixedly connected to the rotating seat 205. The higher end of the second support rod 206 is hinged to the second support column 207, and the first support column 204 and the second support column 207 are slidably connected. A sleeve 208 is slidably fitted onto the lower end of the second support rod 206. A first motor 211 is fixed to the moving platform 202. The output end of the first motor 211 is connected to a first lead screw 210. A lifting seat 209 is threaded onto the first lead screw 210 and is rotatably connected to the sleeve 208. In this embodiment, the cross-section of the mold body 1 is rectangular, and the mold body 1 is arranged at an angle for casting inclined bridge piers. The support mechanism 2 is used to fix and support the mold body 1 to prevent the mold body 1 from tilting or moving during the pouring process, which would affect the construction quality of the bridge pier.The supporting truss 201 is a frame structure formed by splicing several horizontal bars and several vertical columns, and is fixedly installed on the ground during use. The moving platform 202 can move left and right, thereby driving the first supporting rod 203, the first supporting column 204 and other components to move synchronously, so that the first supporting column 204 moves closer to or further away from the mold body 1. The first supporting column 204 is fixedly installed on the mold body 1 with fastening bolts, which facilitates installation and disassembly and reduces construction difficulty. The first supporting rod 203 and the second supporting rod 206 are both straight rods, and the angle between the first supporting rod 203 and the moving platform 202 should be between 20° and 45°, playing the main supporting (or load-bearing) role. An inverted L-shaped rod is integrally fixed on the moving platform 202, and the rotating seat 205 is rotatably connected to the top of the inverted L-shaped rod, so that the second supporting rod 206 can rotate at a certain angle. The first supporting column 204 is provided with an I-shaped groove on the side close to the mold body 1, and the second supporting column 207 is an I-shaped structure that cooperates with the I-shaped groove, so that... The side of the first support column 204 near the mold body 1 is flush with the side of the second support column 207 near the mold body 1, thus ensuring that the first support column 204 and the second support column 207 can fit well with the side of the mold body 1. The first lead screw 210 is vertically arranged above the moving platform 202. The first motor 211 is used to drive the first lead screw 210 to rotate. Due to the limiting effect of the second support rod 206, the first lead screw 210 can drive the lifting seat 209 to move up and down. The sleeve 208 is slidably connected to the second support rod 206, so that the sleeve 208 can slide relative to the second support rod 206 during the lifting process, and the second support rod 206 will rotate. At the same time as the second support rod 206 rotates, it will drive the first support column 204 and the second support column 207 to slide relative to each other synchronously, and the tilt angle of the column composed of the first support column 204 and the second support column 207 will change synchronously, so as to adjust or correct the tilt angle of the mold body 1 and ensure the construction quality. Furthermore, in this embodiment, the support mechanism 2, excluding the support truss 201, comprises two or more structural components. All components used in this embodiment are commercially available.

[0019] Specifically, such as Figure 1 , 3As shown, the mold body 1 includes an upper base 11, a lower base 12, an assembly segment 13, and a fixing member 14. The upper base 11, the lower base 12, and the assembly segment 13 are all rectangular structures. Two or more assembly segments 13 are stacked between the upper base 11 and the lower base 12, and adjacent assembly segments 13 are connected by the fixing member 14. The upper base 11 and the lower base 12 are detachably connected to one of the assembly segments 13. In this embodiment, the upper base 11 and lower base 12 have rectangular cross-sections and right-angled trapezoidal cross-sections. Both the upper base 11 and lower base 12 are connected to the assembly segment 13 via right-angled sides. The assembly segment 13 has rectangular cross-sections in both the transverse and longitudinal directions. This allows for the replacement of different upper bases 11 and lower bases 12 when casting piers with different inclination angles. Furthermore, construction workers can select the number of assembly segments 13 according to the required pier height, thus obtaining mold bodies 1 with different inclination angles and heights. This eliminates the need for specially made templates, improving the applicability of the device and reducing construction costs. The fasteners 14 connect two adjacent assembly segments 13 into a single unit, ensuring the overall strength of the assembled mold body 1. Both the upper base 11 and lower base 12 are detachably connected to the assembly segment 13 using bolts. Specifically, such as Figures 3-4As shown, the assembly segment 13 includes a long template 131, a second slider 133, and a sealing airbag 134. Four long templates 131 are spliced ​​to form a rectangular casting area. A groove 132 is provided laterally at the tail end of the long template 131. The second slider 133 is slidably connected in the groove 132, and one end of the second slider 133 is fixedly connected to the head end of the long template 131. Sealing airbags 134 are provided on both sides of the second slider 133. One end of the sealing airbag 134 is fixed to the inner wall of the groove 132, and a compression spring is also provided inside the sealing airbag 134. In this embodiment, the long template 131 is a flat plate structure, the groove 132 is located at the tail end of the long template 131 and is a long strip structure, and the cross-section of the second slider 133 is a rectangular structure, which is adapted to the cross-sectional dimensions of the groove 132. The second slider 133 can slide in the groove 132, so that the entire assembly segment 13 does not need to be disassembled when moving the position of the long template 131, making construction more convenient. The sealing airbag 134 is preferably a rubber airbag, which is not prone to concrete adhesion and has elasticity. During use, by inflating the sealing airbag 134, it expands, thereby pressing against the inner wall of the slide groove 132 and the side wall of the second slider 133, filling the slide groove 132 and preventing concrete leakage from the gaps. The compression spring is always in a compressed state. Its function is to ensure that the end of the sealing airbag 134 is always in contact with the side wall of the second slider 133 during the sliding process of the second slider 133. It also plays a certain role in positioning and fixing the sealing airbag 134, preventing it from protruding outside the slide groove 132. In addition, after construction, the gaps where the four long templates 131 meet need to be filled with sealing filler (such as sealant) to prevent concrete leakage from the gaps during pouring.

[0020] Specifically, such as Figures 3-4 As shown, a fastening bolt 135 is threadedly connected to the second slider 133, and a triangular positioning block 136 is rotatably connected to the fastening bolt 135. A triangular positioning groove 137 that mates with the triangular positioning block 136 is provided on the outer wall of the long template 131. In this embodiment, the fastening bolt 135 is located at the end of the second slider 133 away from the connected long template 131, and the end of the second slider 133 extends out of the groove 132. The end of the fastening bolt 135 has a threaded section, is threadedly connected to the second slider 133, and can be removed from the second slider 133. The triangular positioning block 136 has a triangular cross-section and a Z-shaped longitudinal section, and during installation, one end of the second slider 133 extends into the inside of the Z-shape. By tightening the fastening bolt 135, the triangular positioning block 136 can be moved and then locked into the triangular positioning groove 137, thereby fixing the position of the second slider 133 to prevent it from sliding in the groove 132 during the concrete pouring process, which would reduce the pouring quality.

[0021] Specifically, such asFigure 4 As shown, the top of the long template 131 is provided with a slot 138, and a sealing rubber layer is provided inside the slot 138. The bottom of the long template 131 is provided with a locking block 139 that cooperates with the slot 138. In this embodiment, the locking block 139 is a conical block and the slot 138 is a conical groove. During installation, the locking block 139 can be locked into the slot 138 to achieve installation positioning and reduce assembly difficulty. After the locking block 139 is locked into the slot 138, it will squeeze the internal sealing rubber layer to seal the contact gap and prevent concrete from leaking through the gap during the pouring process.

[0022] Specifically, such as Figure 3 As shown, the fastener 14 includes a collar 141, a flange 142, a tie bar 143, and a fastening nut 144. The collar 141 is sleeved on the second slider 133. Both sides of the collar 141 have flanges 142 with through holes. The tie bar 143 passes through the through holes and connects to the fastening nut 144, thus fixing the two adjacent long templates 131 together. In this embodiment, the collar 141 is a rectangular ring. After the long templates 131 are assembled, it is installed on the second slider 133. One side of the collar 141 abuts against the outer wall of the long template 131, and the other side abuts against the triangular positioning block 136. The triangular positioning block 136 then fixes the collar 141, preventing it from falling off the second slider 133. The protruding edges 142 are symmetrically arranged on both sides of the collar 141, and the protruding edges 142 on the upper and lower adjacent collars 141 are aligned. The top of the tie bar 143 passes through the through hole on the upper protruding edge 142, and the bottom of the tie bar 143 passes through the through hole on the lower protruding edge 142. Then, under the action of the fastening nut 144, the two second sliders 133 are tightened. At this time, the second sliders 133 will also squeeze the long template 131, so that the sealing rubber layer in the slot 138 is also pressed simultaneously to ensure the sealing effect.

[0023] Specifically, such as Figure 2As shown, the mobile platform 202 is also equipped with a drive unit, which includes a support plate 212, a sliding guide rail 213, a second motor 214, and a second lead screw 215. The support plate 212 is horizontally fixed on the support truss 201, and the sliding guide rail 213 is provided on the support plate 212. The mobile platform 202 is slidably connected to the sliding guide rail 213. The second motor 214 is fixed on the support plate 212, and the output end of the second motor 214 is connected to the second lead screw 215, and the second lead screw 215 is threadedly connected to the mobile platform 202. In this embodiment, due to the complex field construction environment and the inevitable errors during the manual installation of the support mechanism 2 and the mold body 1, the support mechanism 2 may fail to provide effective support, or even cause the mold body 1 to tilt, affecting the construction quality. The drive unit can drive the moving platform 202 to move, thereby adjusting the distance between the large support column composed of the first support column 204 and the second support column 207 and the support truss 201, ensuring that the large support column can fit against the side of the mold body 1 and achieve good support. The support plate 212 is horizontally arranged, and two sliding guide rails 213 are provided, both of which are horizontally fixed to the top surface of the support plate 212. The second lead screw 215 is horizontally arranged above the support plate 212, and the second motor 214 can drive the second lead screw 215 to rotate, thereby causing the moving platform 202 to slide left and right on the sliding guide rails 213. When the second motor 214 rotates forward, the moving platform 202 slides to the right; when the second motor 214 rotates in reverse, the moving platform 202 slides to the left.

[0024] Specifically, such as Figure 1 As shown, the rotating seat 205 is located at the end of the second support rod 206 away from the second support column 207.

[0025] This embodiment also provides a construction method for a bridge pier column formwork that is easy to assemble and disassemble, including the following steps: S1. Construction preparation: Survey and clear the construction site, and conduct surveying and setting out according to the construction location of the bridge piers; S2. Install the mold body 1: First, fix the lower base 12 on the ground at the construction location, then install the assembly segments 13 layer by layer on the lower base 12 until the mold body 1 reaches the set height, and then install the base 11 on the top assembly segment 13. S3. Installing Support Mechanism 2: First, install the support truss 201 on the ground on one side of the inclined direction of the mold body 1. Then, assemble the remaining components except for the support truss 201 (or assemble them in advance before construction) and fix them onto the support truss 201, ensuring that the support plate 212 is horizontally arranged. Then, start the first motor 211 and the second motor 214. The first motor 211 will drive the first lead screw 210 to rotate. The rotation of the first lead screw 210 will drive the lifting seat 209 to rise and fall, thereby driving the second support column 207 to rotate through the sleeve 208. The rotation of the second support column 207 will drive the second support column 207 to move synchronously, thereby making the first The large support column structure, composed of a support column 204 and a second support column 207, rotates to the same tilt angle as the mold body 1. The second motor 214 drives the second lead screw 215 to rotate. The rotation of the second lead screw 215 drives the moving platform 202 to move closer to the mold body 1, so that the large support column abuts against the tilted surface of the mold body 1 and is fixed to the mold body 1 with bolts to support the mold body 1. In addition, by controlling the tilt angle of the large support column through the first motor 211, the tilt angle of the mold body 1 can also be adjusted or corrected to eliminate the adverse effects on the construction quality of the bridge pier caused by errors such as manual installation.
