Description

Technical Field

[0001] The utility model relates to the technical field of pipe arrangement moulds, in particular to a pipe arrangement mould for precast concrete. Background Art

[0002] In recent years, there are more and more emergency power grid constructions, which require that the entire process from design to construction be carried out in a very short time in accordance with design standards, standardized construction, factory processing, and efficient prefabricated construction. Cable line construction requires prefabricated pipe components. Such prefabricated construction greatly shortens the construction period and provides strong guarantees for various emergency power grid constructions. At present, underground cable pipes are mainly cast in place, that is, single-hole pipes are placed after the pipe trench is excavated, and finally cast into a whole with concrete.

[0003] However, some of the existing pipe-laying molds for precast concrete are not convenient to quickly open the mold and take out the formed product after the concrete is poured and formed. The traditional connection between the mold side panels is fixed by bolts. When disassembly is required, tools are needed to disassemble and assemble the bolts, which wastes a lot of time and reduces work efficiency. For this reason, we propose a pipe-laying mold for precast concrete to solve the above problems. Utility Model Content

[0010] Further preferably, the rectangular rod is slidably sleeved on the outside of the square rod, and a spring movably sleeved on the outside of the square rod is fixedly connected between the bottom end of the rectangular rod and the top of the corresponding fixed block.

At this time, the two side templates 3 are moved to both sides, and the side templates 3 drive the card block 24 to separate from the card slot 4, and the side template 3 is separated from the vertical plate 2. At this time, the formed product can be taken out from between the two vertical plates 2. After the concrete is poured and formed, it is convenient to quickly open the mold and take out the formed product. There is no need to use tools to disassemble and assemble the bolts, which saves a lot of time and improves work efficiency.

[0023] In this embodiment, specifically: a winding shaft 14 is rotatably connected to the inner walls of both sides of the base 1, and the end of the flexible steel rope 12 passes around the corresponding fixed pulley 13 and extends into the base 1 and is fixedly connected to the outer side of the winding shaft 14;

[0024] In this embodiment, specifically: a gear 15 is fixedly connected to the outer side of the winding shaft 14, and a rack 16 is meshed with the bottom of the gear 15;

[0025] In this embodiment, specifically: a rectangular plate 17 is fixedly connected to the bottom of the rack 16, two screws 18 are rotatably connected between the front inner wall and the rear inner wall of the base 1, and the rectangular plate 17 is threadedly sleeved on the outside of the screw 18, and two positioning rods 20 are fixedly connected between the front inner wall and the rear inner wall of the base 1, and the rectangular plate 17 is slidably sleeved on the outside of the corresponding positioning rods 20;

[0029] The present invention is in operation: when in use, after the concrete pouring is completed, when the formed product needs to be taken out from between the two vertical plates 2, the knob 19 is turned forward, the rotation of the knob 19 drives the screw 18 to rotate, the rotation of the screw 18 drives the rectangular plate 17 to move, the rectangular plate 17 slides on the outside of the positioning rod 20, the rectangular plate 17 drives the rack 16 to move, the rack 16 drives the gear 15 to rotate, the rotation of the gear 15 drives the corresponding winding shaft 14 to rotate, and the winding shaft 14 winds the two flexible steel ropes 12. The flexible steel rope 12 slides on the outside of the fixed pulley 13 and drives the cross block 11 to move downward. The cross block 11 drives the rectangular rod 9 to move. The rectangular rod 9 slides on the outside of the positioning rod 20. The rectangular rod 9 compresses the spring 23 during the movement. The rectangular rod 9 drives the ball 10 to separate from the limit block 7 and the triangular block 8. At this time, the two side templates 3 are moved to both sides. The side templates 3 drive the clamping block 24 to separate from the clamping slot 4. The side template 3 is separated from the vertical plate 2. At this time, the formed product can be taken out from between the two vertical plates 2.

[0030] When it is necessary to install the two side templates 3, the side template 3 is moved in the direction close to the vertical plate 2, and the side template 3 drives the clamping block 24 to be clamped with the clamping slot 4, and the side template 3 drives the rectangular block 5 to move, and the rectangular block 5 drives the L-shaped block 6 to move. During the movement, the L-shaped block 6 drives the triangular block 8 to move, and the inclined surface of the triangular block 8 contacts the ball 10 and generates an extrusion force. Under the action of the extrusion force, the ball 10 drives the rectangular rod 9 to move downward, and the rectangular rod 9 slides on the outside of the square rod 22 and compresses the spring 23. When the inclined surface of the triangular block 8 is staggered with the ball 10, the spring 23 in the compressed state is reset, and the elastic force of the spring 23 drives the rectangular rod 9 to move upward, and the rectangular rod 9 drives the ball 10 to move, and the rectangular rod 9 moves to between the corresponding limit block 7 and the triangular block 8. At this time, the mold is installed, thereby forming a pipe arrangement mold for precast concrete. After the concrete is poured and formed, it is convenient to quickly open the mold and take out the formed product. There is no need to use tools to disassemble and assemble the bolts, which saves a lot of time and improves work efficiency.
