Referring to fig. 1 and 2, a box culvert core mold, the left and right structures of which are the same, comprises a support 10, and the bottom of the support 10 is provided with a plurality of wheels 130 and a plurality of foot cups 140, so that the support 10 can move and be lifted. The top of support 10 is equipped with roof 20, and the both ends of roof 20 rotationally articulates respectively has upper left corner board 30 and upper right corner board 40, and upper left corner board 30 and upper right corner board 40 rotationally articulates respectively has left side board 50 and right side board 60, and left side board 50 and right side board 60 are located the both sides of support 10 respectively, are equipped with the regulation pole 80 that a plurality of drive left side board 50 and right side board 60 keep away from support 10 on the support 10.

When the box culvert is manufactured, the bottom of the box culvert is poured firstly, the core mould is moved to the position of the hole through the wheels 130, the support 10 is jacked up through the foot cups 140, and the distance between the support 10 and the left side plate 50 and the distance between the support 10 and the right side plate 60 are adjusted through the adjusting rods 80, so that the size of the core mould is equal to the size of the designed hole. After the box culvert is manufactured, the distance between the support 10 and the left side plate 50 and the distance between the support 10 and the right side plate 60 are reduced through the adjusting rods 80, and the support 10 descends through the foot cups 140, so that the core mould demoulding is simple and convenient. The core mould can be produced in batch in advance, the time and labor for temporarily building the core mould are reduced, the core mould does not need to be dismantled, the core mould can be directly recycled, the production cost is effectively reduced, and the production speed is improved.

Further, the left side plate 50 and the right side plate 60 are both provided with a connecting rod 70, and the connecting rod 70 can extend into the side wall of the bottom of the box culvert. The side wall of the bottom of the box culvert can be provided with connecting holes in advance, and in the process that the support 10 rises, when the connecting rods 70 correspond to the connecting holes at the bottom of the box culvert, the connecting rods 70 extend into the connecting holes at the bottom of the box culvert, so that the connecting rods 70 play a role in supporting the left side plate 50 and the right side plate 60, the connecting rods 70 share the weight of part of the core mould, and the load of the foot cups 140 is reduced.

The adjusting rod 80 is a jackscrew, the adjusting rod 80 is connected with the bracket 10 through a nut, and one end of the adjusting rod 80 is abutted against the left side plate 50/the right side plate 60. The distance between the bracket 10 and the left and

right side plates

50 and 60 can be adjusted by rotating the adjusting rod 80, and the operation is simple and convenient.

The left side plate 50 and the right side plate 60 are identical in structure, a first longitudinal rod 90, a vertical rod 100 and a second longitudinal rod 110 are sequentially arranged on the side surface, close to the support 10, of the left side plate 50, and one end of the adjusting rod 80 is abutted to the second longitudinal rod 110. The first vertical bar 90, the vertical bar 100 and the second vertical bar 110 enhance the structural strength of the left/right side plate 50/60, and when the adjusting bar 80 presses against the second vertical bar 110, the first vertical bar 90, the vertical bar 100 and the second vertical bar 110 convert the point force of the adjusting bar 80 into the surface force of the left/right side plate 50/60. First vertical pole 90, montant 100 and second vertical pole 110 are channel-section steel, channel-section steel and square steel respectively, and channel-section steel and square steel can also alleviate the weight of mandrel under the requirement that satisfies structural strength, and when adjusting pole 80 roof pressure second vertical pole 110, the structural strength of square steel is greater than the channel-section steel, avoids second vertical pole 110 to warp.

The bracket 10 is connected with the left upper corner plate 30 and the right upper corner plate 40 through the opposite pulling piece 120, and two ends of the opposite pulling piece 120 can be stretched and contracted simultaneously. The pair of pulling members 120 allows both the left upper gusset 30 and the right upper gusset 40 to be supported by the bracket 10, preventing the left upper gusset 30/the right upper gusset 40 from being deformed by the heavy pressure of the concrete. In detail, the pull-pair member 120 includes an adjusting member 121, and an upper brace 122 and a lower brace 123 disposed at two ends of the adjusting member 121, wherein the adjusting member 121 is connected to the upper brace 122 and the lower brace 123 through threads, the upper brace 122 is hinged to the upper left corner plate 30/the upper right corner plate 40, and the lower brace 123 is hinged to the bracket 10. The adjusting member 121 is rotated to simultaneously extend the upper brace 122 and the lower brace 123 from the adjusting member 121 or simultaneously retract the upper brace and the lower brace into the adjusting member 121. And the opposite pulling pieces 120 are arranged between the bracket 10 and the left side plate 50 and between the bracket 10 and the right side plate 60, two ends of the opposite pulling pieces 120 are respectively connected with the bracket 10 and the left side plate 50/right side plate 60, and the opposite pulling pieces 120 play a role in strengthening the strength of the connecting mechanism of the bracket 10 and the left side plate 50 and the right side plate 60.

The top plate 20 is connected with the left upper corner plate 30 and the right upper corner plate 40 through hinges, the left upper corner plate 30 is connected with the left side plate 50, and the right upper corner plate 40 is connected with the right side plate 60 through hinges. The hinge allows the upper left corner panel 30 to be easily rotated about the left side panel 50 and the upper left corner panel 30 to be easily rotated about the top panel 20. Similarly, the right upper corner plate 40 can be easily rotated around the right side plate 60, the right upper corner plate 40 can be easily rotated around the top plate 20, and the hinge has a simple structure and is convenient to install and use.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
