Description

Technical Field

[0001] The utility model belongs to the technical field of pipe segment moulds, in particular to a high-precision pipe segment mould. Background Art

[0002] With the continuous development of urban rail, the continuous research and development of shield tunneling machine manufacturing and construction technology, the requirements for "shield segment molds" (referred to as segment molds) are becoming more and more advanced. Among them, the concrete segments produced by them have also become one of the important key technologies related to the quality of the entire tunnel project in shield construction:

[0003] During the segment production process, the concrete inside the mold needs to be vibrated to eliminate bubbles inside the segment and ensure the accuracy and quality of segment production. Due to mold structure problems, the concrete edges of the mold cannot be effectively vibrated and vented, and bubbles are still prone to appear in the formed segments.

[0004] Therefore, the existing high-precision segment molds cannot meet the needs of actual use, so the market is in urgent need of improved technologies to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a high-precision segment mold, by arranging a vibrator at the bottom end of the segment mold, and arranging a spring and a connecting plate to connect the segment mold to a base plate, and at the same time further connecting the mold fixing plate and the base plate through the cooperation of a universal ball seat, a universal ball groove and a universal ball rod, so that the segment mold is limited and shaken when the vibrator is working, thereby solving the problem of vibrating the concrete inside the mold during the segment production process to eliminate bubbles inside the segment and ensure the accuracy and quality of the segment production. Due to the problem of the mold structure, the concrete edge of the mold edge cannot be effectively vibrated and vented, and the formed segment is still prone to bubbles.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a high-precision pipe segment mold, comprising four mold side plates arranged at the top of a mold fixing plate, four springs with connecting plates fixed at both ends, and a bottom plate, two vibrators are evenly fixed in the middle of the bottom end of the mold fixing plate, four connecting plates located at the top of the four springs are evenly fixed at the four corners of the bottom end of the mold fixing plate, and four connecting plates located at the bottom of the four springs are evenly fixed at the four corners of the top end of the bottom plate. The pipe segment mold is composed of the mold fixing plate, the mold side plates and the top cover, and the vibrator is convenient for driving the mold fixing plate to shake, and the mold fixing plate and the bottom plate are connected by the connection plate and the spring, and the position of the mold fixing plate is limited and fixed by the connection plate, the spring and the bottom plate, so that the shaking position of the mold fixing plate is limited while the shaking of the mold fixing plate is facilitated to prevent the position of the mold fixing plate from shifting.

[0008] Furthermore, through holes are provided on the tops of the two side plates of the mold, and leveling plates are slid inside the two through holes. The through holes and the leveling plates are used together to level the segment mold after grouting, ensuring that there is not too much concrete inside the segment mold, thereby ensuring that the produced segments have high precision. The position of the leveling plates is limited by the through holes, which is convenient for the staff to use the leveling plates.

[0009] Furthermore, limiting rings are fixedly sleeved on the outer cylindrical surfaces at both ends of the flat board, and handles are fixedly provided at the middle of the two limiting rings opposite to each other. The limiting rings further increase the movement stability of the flat board, and the handles facilitate the staff to push the flat board.

[0010] Furthermore, four universal ball seats are evenly fixed on the bottom end of the mold fixing plate and the top end of the base plate, and universal ball grooves are opened inside the universal ball seats, and the positions of the universal ball seats are fixed by the mold fixing plate and the base plate.

[0011] Furthermore, the plurality of universal ball grooves are grouped in pairs, and four universal ball rods are evenly rotating inside the four groups of universal ball grooves. The positions of the mold fixing plate and the base plate are limited in one step through the cooperation of the universal ball grooves, the universal ball rods and the universal ball seats, thereby further increasing the shaking stability, reducing the bearing capacity of the spring and increasing the service life of the spring.

[0012] The utility model has the following beneficial effects:

[0013] The utility model arranges a vibrator at the bottom end of the segment mold, and arranges a spring and a connecting plate to connect the segment mold with the bottom plate. At the same time, a universal ball seat, a universal ball groove and a universal ball rod are used to further connect the mold fixing plate and the bottom plate. When the vibrator is working, the segment mold is limited and shaken, and then the concrete inside the segment mold is vibrated and exhausted, so that the concrete edge of the mold edge can be effectively vibrated and exhausted, ensuring that no bubbles will appear in the formed segment.
