Description

Technical Field

[0001] The utility model relates to the technical field of hole prefabricated component molds, in particular to a prefabricated component mold for plugging bridge holes. Background Art

[0002] In the construction of bridges, holes are often left for the convenience of use and operation during the construction process. The holes are usually used to install template tie rods to support and fix the template. They can also be used as ventilation holes and drainage holes. After the bridge is completed, when the holes need to be sealed, it is generally necessary to seal one side of the hole first, and then use a grouting machine to inject cement mortar. The construction process is relatively cumbersome, difficult for construction workers to operate, and low construction efficiency.

[0003] Holes can also be sealed by combining precast concrete cylinders with micro-expanding cement mortar. The micro-expanding cement mortar is composed of anti-cracking mortar, expansion agent, ordinary Portland cement and water. The precast concrete cylinder is inserted into the hole, and then the micro-expanding cement mortar is filled into the hole to complete the sealing of the hole. However, when making concrete cylinders, they can only be made one by one, which is difficult to produce in batches. In addition, the concrete cylinders are dried by natural drying during the production process, which makes the production efficiency of the concrete cylinders slow. Utility Model Content

[0031] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0032] See also Figure 1-Figure 4The utility model provides a prefabricated mold for plugging bridge holes. Concrete cylinders of different diameters can be manufactured simultaneously through multiple sets of prefabricated molds 001. The setting of the hot air blower 330 reduces the drying time of the concrete and increases the manufacturing efficiency of the concrete cylinders.

[0033] The prefabricated mold 001 includes a screw nut 100, and a limiting block 110 is fixedly installed at the front and rear ends of the screw nut 100. A limiting hole 120 for the long rod 210 to rotate is opened in the middle of the screw nut 100. A slider 121 is fixedly installed in the hole cavity of the slider 121. A limiting hole 130 is opened at the front and rear ends of the screw nut 100 for cooperating with the limiting rod 312 to limit the screw nut 100. Two symmetrically arranged precast molds 001 form a group. When the control component 200 is started, the slider 121 on the first precast mold 001 slides in the groove cavity of the first spiral groove 211, thereby controlling the precast mold 001 to move to the left, and the slider 121 on the second precast mold 001 moves in the groove cavity of the second spiral groove 212, thereby controlling the precast mold 001 to move to the right, so that the two precast molds 001 are away from the concrete cylinder, which is convenient for disassembly of the concrete cylinder.

[0034] A first module 140 is installed at the front end of the screw nut 100, and the first module 140 is fixedly installed at one end of the limit block 110. Two first semicircular grooves 141 are provided on one side of the first module 140, and the groove wall of the first semicircular groove 141 is fixedly provided with an anti-stick coating 142. The provision of the anti-stick coating 142 can prevent the concrete cylinder from cracking due to adhesion between the concrete cylinder and the inner wall of the first semicircular groove 141 when the dried concrete cylinder is disassembled.

[0035] The rear end of the lead screw nut 100 is fixedly mounted with a second module 150, one side of which is provided with two second semicircular grooves 151, the groove cavity of the second semicircular groove 151 is provided with an anti-stick coating 152, and the diameters of the first semicircular groove 141 and the second semicircular groove 151 are different. The provision of the anti-stick coating 152 prevents the concrete cylinder from being cracked due to adhesion between the concrete cylinder and the inner wall of the second semicircular groove 151 when the dried concrete cylinder is disassembled. The first module 140 is provided with an air inlet 160 and an air outlet 161, and both the air inlet 160 and the air outlet 161 are provided on the second module 150. It is convenient for hot air to accelerate the drying of the concrete cylinder inside the first module 140 and the second module 150.

[0036] A control device 002 for controlling the precast molds 001 to move closer to each other is installed in the middle of the precast mold 001, and multiple groups of precast molds 001 slide on the control device 002. The control device 002 includes a control assembly 200, and the control assembly 200 includes a long rod 210, and the rod body of the long rod 210 is provided with a first spiral groove 211 and a second spiral groove 212 for controlling the movement of the precast mold 001, and the first spiral groove 211 and the second spiral groove 212 have opposite rotation directions. A motor 220 for controlling the long rod 210 to rotate is installed at one end of the long rod 210.

[0037] When it is necessary to cast a concrete cylinder, the motor 220 controls the long rod 210 to rotate, so that the first slider 121 slides in the groove cavity of the first spiral groove 211, and the second slider 121 slides in the groove cavity of the second spiral groove 212. Since the first spiral groove 211 and the second spiral groove 212 have opposite rotation directions, the two prefabricated molds 001 are close to each other, and finally the two prefabricated molds 001 are fitted, and the two first semicircular grooves 141 form a first cylindrical cavity, and the two second semicircular grooves 151 form a second cylindrical cavity. After the two cylindrical cavities are formed, the concrete cylinder can be made.

[0038] The lower end of the control device 002 is provided with a support device 003 for supporting and limiting the control device 002. The support device 003 includes an operating table 300, and a protection box 310 for protecting the control assembly 200 is fixedly installed in the middle of the operating table 300 to prevent concrete from spilling into the groove cavities of the first spiral groove 211 and the second spiral groove 212, causing the prefabricated mold 001 to be unable to move normally.

[0039] The front and rear ends of the protection box 310 are provided with a slide groove 311 for the first limit block 110 to slide. The protection box 310 is fixedly installed with a limit rod 312 inside, and the limit rod 312 slides in the cavity of the second limit hole 130. The upper end of the operating table 300 is installed with a second limit block 320 for limiting the control assembly 200.

[0040] A hot air blower 330 is installed at the upper end of the operating table 300 for accelerating the condensation of the concrete cylinder in cooperation with the prefabricated mold 001. A first delivery pipe 331 is fixedly installed at the upper end of the hot air blower 330, a second delivery pipe 332 is fixedly installed at the upper end of the first delivery pipe 331, a third delivery pipe 333 is fixedly installed at the front and rear ends of the second delivery pipe 332, a plurality of fourth delivery pipes 334 are fixedly installed at the middle of the third delivery pipe 333, a flexible bellows 335 is installed at one end of the fourth delivery pipe 334, and one end of the flexible bellows 335 is connected to the air inlet 160.

[0041] By starting the hot air blower 330, hot air is transported to the interior of the first module 140 and the second module 150 through the first delivery pipe 331, the second delivery pipe 332, the third delivery pipe 333, the fourth delivery pipe 334, the flexible bellows 335 and the air inlet 160, heating the middle inner cavity of the first module 140 and the second module 150, and the heat is conducted to the concrete cylinder through the first module 140 and the second module 150, thereby accelerating the drying rate of the concrete cylinder.

[0042] When the concrete cylinder made by the utility model is used to block the hole of the bridge, the concrete cylinder needs to be wetted first, and then dipped in the micro-expansive cement mortar, the residence time is maintained at 3-5S, and then it is smoothly inserted into the hole after being wetted by watering. After the insertion, it should be ensured that the slurry overflows. After the prefabricated concrete cylinder is installed, the micro-expansive cement mortar is cleaned on the surface overflowed, and the micro-expansive cement mortar is used to level the outside, and finally the surface is polished to complete the blocking of the bridge hole.

[0043] Based on the above content and the accompanying drawings, those skilled in the art can understand and implement the utility model. In addition, any non-creative modifications made to the utility model by those skilled in the art without making creative work still fall within the scope of protection of the utility model.
