Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place box beam templates, in particular to a cast-in-place box beam template installation structure. Background Art

[0002] Cast-in-place box girder refers to a box-shaped beam structure formed by pouring concrete on site, which generally includes a box bottom plate, side plates and top plate. Box girders are widely used in large-span bridges, subway tunnels and other projects, and the cast-in-place box girder formwork is the template used for cast-in-place box girder construction.

[0003] At present, the cast-in-place box girder formwork on the market is more troublesome to install and close the mold, and it is easy to loosen after closing the mold. It is time-consuming and laborious to dismantle and demould, which is easy to delay the overall construction progress. Utility Model Content

[0004] The utility model aims to provide a cast-in-place box beam template installation structure to solve the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a cast-in-place box beam template installation structure, comprising a template A and a template B, the front end of the template A is provided with a template groove, the rear end of the template B is fixedly connected with a template block, and the side of the template A is provided with a convenient installation mechanism; the convenient installation mechanism comprises a mounting block, a hydraulic chamber and an insertion rod, the mounting block is fixedly connected to the side of the template A, the front end of the mounting block is provided with a slot, the top of the slot is provided with a groove, a telescopic spring is arranged inside the groove, an arc block is slidably connected to the inside of the groove through the telescopic spring, the hydraulic chamber is fixedly connected to the rear end of the template A, a pull rod is slidably connected to the inner piston of one end of the hydraulic chamber, and connecting rods are slidably connected to the inner pistons of the other two ends of the hydraulic chamber, one end of the connecting rod away from the hydraulic chamber is fixedly connected to the top of the arc block, one end of the insertion rod is fixedly connected to the side of the template B, a card slot is arranged on the top of the other end of the insertion rod, and a buffer dislocation mechanism is arranged inside the slot.

[0007] Furthermore, the opening size of the slot corresponds to the size of the end of the insertion rod away from the template B, and when the template A and the template B are molded together, the end of the insertion rod away from the template B will be inserted into the slot.

[0008] Furthermore, the opening size of the slot is equal to the opening size of the groove, and one third of the arc block is located outside the groove in the initial state, and the arc block can be inserted into the slot.

[0009] Furthermore, the arc surface of the arc block faces the slot opening direction, and the depth of the groove is greater than the length of the arc block. When the arc surface of the arc block is squeezed, it will move into the groove, and the arc block can be completely retracted into the groove.

[0010] Furthermore, the buffer dislocation mechanism includes a buffer spring, a buffer plate and a deceleration block, the buffer plate is slidably connected to the inside of the slot through the buffer spring, the top and bottom of the buffer plate are fixedly connected to a contact rod, and the deceleration block is fixedly connected to the inner wall of the slot.

[0011] Furthermore, the end of the contact rod away from the buffer plate is arc-shaped, and the length of the contact rod is greater than the distance from the buffer plate to the speed reduction block. When the buffer plate moves into the slot, the arc-shaped end of the contact rod will be squeezed by the speed reduction block.

[0012] Furthermore, the deceleration block is semi-cylindrical as a whole, and is made of rubber. When the arc-shaped end of the contact rod is squeezed against the semi-cylindrical rubber deceleration block, resistance is generated.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a convenient installation mechanism, so that when template A and template B are installed and molded, the arc block is inserted into the slot through the cooperation of components such as the insertion rod, the installation block, the groove, and the telescopic spring. The arc block is inserted into the slot, which makes template A and template B firmly fixed together and unable to be separated. When they need to be disassembled for demoulding, pulling the pull rod will make the arc block shrink into the groove and leave the slot. At this time, template A and template B can be separated. The installation and disassembly are simple and it is not easy to delay the construction progress.

[0015] 2. The utility model has a buffer dislocation mechanism, so as to achieve the installation and mold closing of template A and template B. When the insert rod is inserted into the slot, the buffer plate, buffer spring, contact rod and other components will cooperate to achieve a buffering effect, thereby preventing template A and template B from colliding with each other and causing damage. When demolding, the buffer spring rebounds and causes the groove and the card slot to be dislocated to help separate template A and template B.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A pull rod 57 is slidably connected to the interior of one end of the hydraulic chamber 56 by a piston, and connecting rods 58 are slidably connected to the interiors of the other two ends of the hydraulic chamber 56 by pistons. The end of the connecting rod 58 away from the hydraulic chamber 56 is fixedly connected to the top of the arc block 55, and one end of the insertion rod 59 is fixedly connected to the side of the template B3. A slot 510 is provided on the top of the other end of the insertion rod 59, and a buffer misalignment mechanism 6 is provided inside the slot 52.

[0027] The opening size of the slot 52 corresponds to the size of the end of the insertion rod 59 away from the template B3. When the template A1 and the template B3 are molded together, the end of the insertion rod 59 away from the template B3 will be inserted into the slot 52.

[0028] The opening size of the slot 510 is equal to the opening size of the groove 53 . In the initial state, one third of the arc block 55 is located outside the groove 53 , and the arc block 55 can be inserted into the slot 510 .

[0029] The arc surface of the arc block 55 faces the opening direction of the slot 52 , and the depth of the groove 53 is greater than the length of the arc block 55 . When the arc surface of the arc block 55 is squeezed, it will move into the groove 53 , and the arc block 55 can be completely retracted into the groove 53 .

[0030] The buffer dislocation mechanism 6 includes a buffer spring 61, a buffer plate 62 and a speed reduction block 64. The buffer plate 62 is slidably connected to the inside of the slot 52 through the buffer spring 61. The top and bottom of the buffer plate 62 are fixedly connected with a contact rod 63. The speed reduction block 64 is fixedly connected to the inner wall of the slot 52.

[0031] The end of the contact rod 63 away from the buffer plate 62 is arc-shaped, and the length of the contact rod 63 is greater than the distance from the buffer plate 62 to the speed reduction block 64 . When the buffer plate 62 moves into the slot 52 , the arc-shaped end of the contact rod 63 will be squeezed by the speed reduction block 64 .

[0032] The deceleration block 64 is semi-cylindrical in shape as a whole, and is made of rubber. When the arc-shaped end of the contact rod 63 is squeezed against the semi-cylindrical rubber deceleration block 64, resistance is generated.

[0033] A specific application of this embodiment is: when it is necessary to install and mold the template A1 and the template B3, the template block 4 at the rear end of the template B3 is aligned with the mold groove 2 at the front end of the template A1 and merged. At this time, the end of the insertion rod 59 away from the template B3 will be inserted into the slot 52. When the insertion rod 59 enters the slot 52, it will squeeze the arc surface of the arc block 55, so that the arc block 55 is retracted into the groove 53, and the telescopic spring 54 is tightened. When the slot 510 at the top of the insertion rod 59 fits with the groove 53, the telescopic spring 54 will rebound and drive the arc block 55 to be stuck in the slot 510. At this time, the insertion rod 59 will not be able to leave the slot 52, so that the template A1 and the template B3 are firmly attached together and cannot be separated. When the template A1 and the template B3 need to be disassembled for demolding, the pull rod 57 is pulled out to the rear end. The movement of the pull rod 57 to the rear end will drive the other two end connecting rods 58 to move upward through the hydraulic pressure in the hydraulic chamber 56. The upward movement of the connecting rods 58 at both ends will drive the arc block 55 to leave the card slot 510 and retract into the groove 53. At this time, the template A1 can be separated from the template B3. Then the telescopic spring 54 rebounds to drive the arc block 55 and the connecting rod 58 to be restored, and the pull rod 57 is also restored. In the process of inserting the insertion rod 59 into the slot 52, it will contact the buffer plate 62 and drive the buffer plate 62 to move toward the rear end of the slot 52. At this time, the buffer spring 61 will absorb the impact force and gradually tighten. When the buffer plate 62 moves toward the rear end of the slot 52, it will also drive the contact rod 63 and the deceleration block 64 to squeeze and generate resistance. The elastic force of the buffer spring 61 and the resistance generated by the contact rod 63 and the deceleration block 64 play a buffering role to prevent the template A1 and the template B3 from colliding with each other and causing damage. When demolding, the rebound of the buffer spring 61 will cause the groove 53 and the card slot 510 to be misaligned, helping to separate the template A1 from the template B3.
