Description

A prefabricated pipe gallery external formwork device Technical Field

[0001] This utility model belongs to the field of pipe gallery mold technology, specifically relating to a prefabricated pipe gallery external mold device. Background Technology

[0002] A pipe gallery is a building structure used to centrally lay large-scale equipment pipelines. In order to improve processing accuracy and speed up construction, existing technologies generally use pipe gallery molds to produce prefabricated pipe galleries in factories, and then transport them to the construction site for splicing and assembly.

[0003] Chinese patent CN212636113U discloses a guide forming mold for the outer protective pipe of a pipe gallery. The solution includes a horizontal guide rail and a vertical guide rail. A side mold a is installed on the upper outer wall of the horizontal guide rail, and a side mold b is installed on the upper outer wall of the vertical guide rail. The above solution utilizes the sliding of two side molds a and two side molds b respectively to easily form a space for pouring concrete, and the two side molds a and two side molds b can be horizontally moved apart after the pipe gallery is poured and formed.

[0004] When producing pipe racks, there will be an adhesive force between the concrete used to pour the pipe racks and the mold. In the above scheme, the contact area between the side mold a and the pipe rack is large, and the side mold a can only move in a direction perpendicular to the side wall of the pipe rack that is in contact with the side mold a. This can easily cause damage to the pipe rack during the demolding process and affect the quality of the finished pipe rack. Summary of the Invention

[0005] The present invention aims to provide a prefabricated pipe gallery outer mold device to reduce damage to the pipe gallery during the demolding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A precast pipe gallery external mold device includes a base, a first side mold, and a second side mold. First guide rails are fixedly installed on the left and right sides of the base, and connecting blocks are fixedly installed at the front and rear ends of the left and right sides of the base. A through groove is formed on the side wall of each connecting block. Second guide rails are fixedly installed on the front and rear sides of the base. Two sets of first side molds are symmetrically arranged on the left and right sides of the base. Rotating shafts are fixedly installed at the bottom of the front and rear sides of each of the two first side molds. Each rotating shaft is movably connected to a corresponding through groove. A first movable seat, which is drivenly connected to the corresponding first side mold, is slidably installed on each of the first guide rails. Two sets of second side molds are arranged on the front and rear sides of the base, and each of the two second side molds is slidably connected to a corresponding second guide rail.

[0008] The principle and effects of this technical solution:

[0009] In the initial state (i.e., usage state one), the inner walls of the two second side molds abut against the side walls of the base, and the inner walls of the two first side molds abut against the side walls of the base. Each rotating shaft abuts against the inner top wall of the corresponding through groove. The two first side molds, the two second side molds, and the base form a casting cavity. Before casting, a forklift is used to insert the inner template into the casting cavity from the front of the base, and the inner template is fixedly connected to the two second side molds. Concrete is then poured into the casting cavity. After the pipe gallery is formed, as shown in usage state two, the two first movable molds move in opposite directions. The first two side molds first move downward relative to the forming pipe gallery. During this process, the concrete for pouring the pipe gallery cannot move with the first side molds. After each rotating shaft contacts the inner bottom wall of the through groove, as shown in usage state three, the two first movable seats continue to move in opposite directions, and the two first side molds rotate away from the pipe gallery. Then, the connection between the inner template and the two second side molds is released, and the two second side molds move in opposite directions. Finally, the formed pipe gallery is hoisted to the appropriate position and the inner template is removed. The connection method between the inner template and the two second side molds is a known prior art.

[0010] With the above settings, the two first side molds slide vertically, which can prevent the concrete of the pipe gallery sidewall that is in contact with the first side mold from adhering to the first side mold. This makes it easier for the device to demold the formed precast pipe gallery, while reducing the damage to the precast pipe gallery during the demolding process and improving the finished quality of the precast pipe gallery.

[0011] In this invention, multiple connecting plates are fixedly arranged at intervals on the front and rear side walls of the first side mold, and multiple locking plates are fixedly arranged at intervals on the left and right side walls of the second side mold. Each locking plate has a locking groove at its bottom near the second side mold end, and the top of each connecting plate can be slidably embedded in the corresponding locking groove. This arrangement ensures that, on the one hand, the connecting blocks abut against the side walls of the second side mold, allowing the second side mold to provide support for the first side mold and improving the stability of the first side mold during installation; on the other hand, the slidable embedding of the tops of the connecting blocks into the locking grooves ensures that when the two first movable seats move in opposite directions, the two first side molds slide downwards first.

[0012] In this invention, a connecting rod is rotatably connected to the top of the first movable seat, and the top of the connecting rod is rotatably connected to the outer wall of the corresponding first side mold. This arrangement achieves the purpose of enabling a transmission connection between the first movable seat and the corresponding first side mold.

[0013] In this utility model, a telescopic rod is also included. A hinge seat is fixedly provided on the top of the second side mold, and the two ends of the telescopic rod are rotatably connected to the hinge seats of the two second side molds.

[0014] In this utility model, the telescopic rod includes a bidirectional screw, and sleeves are respectively fitted at both ends of the bidirectional screw. The two sleeves are rotatably connected to the hinge seats on the two second side molds at their ends that are far apart from each other.

[0015] The principle and effects of this technical solution:

[0016] Before pouring concrete, rotate the sleeves at both ends of the bidirectional screw to adjust the overall length of the telescopic rod. Then, rotate the two sleeves at opposite ends to the hinge seats on the two second side molds.

[0017] By adding the connection at the top of the two second side molds through the above settings, it is possible to prevent the two second side molds from deforming due to pressure during the concrete pouring process.

[0018] In this invention, a second movable seat is slidably mounted on the second guide rail, and the bottom of the second side mold is fixedly connected to the top of the second movable seat. This arrangement achieves the purpose of allowing the two second side molds to slide and connect with their respective second guide rails.

[0019] In this invention, a rib is fixedly provided on the outer side wall of the second side mold, and the bottom of the rib is fixedly connected to the top of the second movable seat. This arrangement enhances the connection between the second side mold and the corresponding second movable seat, while also increasing the rigidity of the second side mold.

[0020] In this invention, a limiting block is fixedly provided on the outer side wall of the two rotating shafts on the first side mold at one end away from each other, which slides against the connecting block. This arrangement prevents the first side mold from moving in the front-to-back direction. Attached Figure Description

A through groove 13 is opened on the side wall of the connecting block 12. Second guide rails 14 are fixedly arranged on the front and rear sides of the base 10. Two sets of first side molds 20 are symmetrically arranged on the left and right sides of the base 10. Rotating shafts 21 are fixedly arranged at the bottom of the front and rear sides of the two first side molds 20. Each rotating shaft 21 is movably connected to a corresponding through groove 13. The axis of the rotating shaft 21 is arranged horizontally, and the rotating shaft 21 can rotate and move vertically relative to the through groove 13. A first movable seat 41, which is transmitted and driven by the corresponding first side mold 20, is slidably arranged on each first guide rail 11. Two sets of second side molds 30 are arranged on the front and rear sides of the base 10, and the two second side molds 30 are slidably connected to the corresponding second guide rail 14.

[0032] In this embodiment, multiple connecting plates 22 are fixedly arranged at intervals on the front and rear side walls of the first side mold 20, and multiple locking plates 31 are fixedly arranged at intervals on the left and right side walls of the second side mold 30. A locking groove 32 is provided at the bottom of the locking plate 31 near the end of the second side mold 30, and the top of each connecting plate 22 can be slidably embedded in the corresponding locking groove 32.

[0033] In this embodiment, a connecting rod 411 is rotatably connected to the top of the first movable seat 41, and the top of the connecting rod 411 is rotatably connected to the outer wall of the corresponding first side mold 20.

[0034] In this embodiment, a telescopic rod 50 is also included. A hinge seat 33 is fixedly provided on the top of the second side mold 30. The two ends of the telescopic rod 50 are rotatably connected to the hinge seats 33 of the two second side molds 30.

[0035] In this embodiment, the telescopic rod 50 includes a bidirectional screw 51, and sleeves 52 are respectively fitted at both ends of the bidirectional screw 51. The two sleeves 52 are rotatably connected to the hinge seats 33 on the two second side molds 30 at their respective ends away from each other.

[0036] In this embodiment, a second movable seat 42 is slidably disposed on the second guide rail 14, and the bottom of the second side mold 30 is fixedly connected to the top of the second movable seat 42.

[0037] In this embodiment, a rib plate 34 is fixedly provided on the outer side wall of the second side mold 30, and the bottom of the rib plate 34 is fixedly connected to the top of the second movable seat 42.

[0038] In this embodiment, the outer side walls of the two rotating shafts 21 on the first side mold 20, which are far apart from each other, are fixedly provided with limiting blocks 211 that slide against the connecting block 12.

[0039] The specific implementation process is as follows:

[0040] In the initial state (i.e., usage state one), the inner walls of the two second side molds 30 abut against the side walls of the base 10, and the inner walls of the two first side molds 20 abut against the side walls of the base 10, respectively. Each of the rotating shafts 21 abuts against the inner top wall of the corresponding through groove 13. The two first side molds 20, the two second side molds 30, and the base 10 form a pouring cavity. Before pouring, a forklift is used to insert the inner template into the pouring cavity from the front of the base 10, and the inner template is fixedly connected to the two second side molds 30. Concrete is then poured into the pouring cavity. After the pipe gallery is formed, as shown in usage state two, the two first side molds 20 are moved in opposite directions. The movable seat 41 and the two first side molds 20 first move downward relative to the forming pipe gallery. During this process, the concrete for pouring the pipe gallery cannot move with the first side molds 20. When each rotating shaft 21 contacts the inner bottom wall of the through groove 13, as shown in the third usage state, the two first movable seats 41 continue to move in opposite directions, and the two first side molds 20 rotate away from the pipe gallery. Then, the connection between the inner template and the two second side molds 30 is released, and the two second side molds 30 move in opposite directions. Finally, the formed pipe gallery is hoisted to the appropriate position and the inner template is removed. The connection method between the inner template and the two second side molds 30 is a known prior art.

[0041] Before pouring concrete, rotate the sleeves 52 at both ends of the bidirectional screw 51 to adjust the overall length of the telescopic rod 50. Then, rotate the two sleeves 52 away from each other to connect with the hinge seats 33 on the two second side molds 30.
