[0062] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0063] Figures 1 to 10The diagram shown is a structural schematic of an embodiment of a prestressed roof slab production line mold for a subway station according to this utility model. The prestressed roof slab production line mold for a subway station includes a mold unit and a tensioning unit, which are connected by multiple reinforcing steel bars 1.

[0064] The mold unit includes a bottom support assembly 2. The bottom support assembly 2 is connected to two fixed side templates 3 that are symmetrically distributed on the left and right. Movable side templates 4 are provided on both sides of the fixed side templates 3. The two movable side templates 4 are symmetrically distributed front and back. A first fastening assembly 5 is connected between the bottom support assembly 2 and the movable side templates 4. A second fastening assembly 6 is connected to the upper part of the two movable side templates 4.

[0065] In this technical solution, the tensioning unit can be used to tension the steel bar 1 to maintain the tension force of the steel bar 1, thereby facilitating the production of prestressed roof slabs using the mold unit. This allows prestressed roof slabs to be produced at the subway station construction site, eliminating the need for transportation of prestressed roof slabs, reducing the production cost of prestressed roof slab installation, improving the efficiency of subway station installation, and enabling the production of prestressed roof slabs in a production line with fast production speed.

[0066] When using it, first assemble the mold unit, then install multiple steel bars 1 to the mold unit and tensioning unit respectively, and then pour concrete into the mold unit. During this process, the tensioning unit is used to maintain the tension of the steel bars 1 to assist in the pouring of concrete. After the concrete solidifies, the mold unit is removed to obtain the prestressed top slab.

[0067] The bottom support assembly 2 includes a bottom mold frame 21, and the bottom of the bottom mold frame 21 is connected to a plurality of fixed legs 22;

[0068] The bottom mold frame 21 is connected to two fixed side templates 23 that are symmetrically distributed front and back, and the bottom mold frame 21 is connected to two through side templates 24 that are symmetrically distributed left and right.

[0069] The two fixed edge templates 23 and the two through edge templates 24 are connected to each other.

[0070] In this technical solution, the bottom support component 2 can be used to support the fixed side template 3 and the movable side template 4.

[0071] The first fastening assembly 5 includes a plurality of large U-shaped brackets 51, which are detachably connected to the top of the two fixed side templates 23 respectively;

[0072] The two side columns of the large U-shaped bracket 51 are connected to mounting blocks 52. The mounting blocks 52 are threadedly connected to the surface of the first fastening threaded column 53. One end of the first fastening threaded column 53 is connected to an abutment plate 54. The side of the abutment plate 54 away from the first fastening threaded column 53 contacts the side of the movable side template 4.

[0073] In this technical solution, the position of the movable side template 4 is fixed by using the first fastening component 5 to read the position, thereby increasing the stability of the mold unit during the production of the prestressed top plate and preventing the movable side template 4 from expanding and deforming.

[0074] The inner wall of the top surface of the large U-shaped bracket 51 is connected to two symmetrically distributed connecting columns 55, and the bottom of the connecting columns 55 on both sides are detachably connected to the top of the movable side template 4.

[0075] In this technical solution, the movable side formwork 4 can be connected using the connecting strip column 55.

[0076] The second fastening assembly 6 includes a plurality of small U-shaped brackets 61, the bottom of which is detachably connected to the top of the movable side templates 4 on both sides;

[0077] The top surface of the small U-shaped bracket 61 is threadedly connected to the surface of the second fastening threaded post 62, and the bottom end of the second fastening threaded post 62 is in contact with the ground.

[0078] In this technical solution, the stability of the mold unit can be increased by using the second fastening component 6.

[0079] When assembling the mold unit, the fixed support 22 is pre-embedded in the ground. Then, the first fastening threaded column 53 is rotated. At this time, under the action of the large U-shaped bracket 51, the first fastening threaded column 53 can drive the abutment plate 54 to move, so that the abutment plate 54 is in close contact with the moving side template 4, stabilizing the moving side template 4 and preventing the fixed side template 3 from expanding and deforming during concrete pouring.

[0080] Furthermore, when in use, rotating the second fastening threaded column 62 causes the small U-shaped bracket 61 to contact the ground, further increasing the stability of the movable side template 4 and facilitating the maintenance of the production quality of the prestressed top plate.

[0081] The tensioning unit includes a fixed tensioning steel beam 7 and a movable tensioning steel beam 8. The fixed tensioning steel beam 7 is connected to two symmetrically distributed fixed piers 9 on the side away from the movable tensioning steel beam 8. The fixed piers 9 are set on the ground.

[0082] A tensioning device 10 is provided between the fixed tensioning steel beam 7 and the movable tensioning steel beam 8. The bottom of the tensioning device 10 is connected to a fixed bracket 11, and the bottom of the movable tensioning steel beam 8 is connected to a sliding component 12. The sliding component 12 is slidably disposed on the top of the bottom bracket 13, and one side of the fixed bracket 11 is connected to one side of the bottom bracket 13.

[0083] In this technical solution, the tensioning unit can be used to tension the steel reinforcement 1, so as to avoid the displacement of the steel reinforcement 1 during the production of prestressed top slab.

[0084] Two sets of symmetrically distributed tensioning devices 10 are provided between the fixed tensioning steel beam 7 and the movable tensioning steel beam 8, with the two ends of the tensioning devices 10 contacting the fixed tensioning steel beam 7 and the movable tensioning steel beam 8 respectively.

[0085] In this technical solution, the tensioning device 10 can provide the driving force for tensioning the reinforcing steel 1.

[0086] The sliding component 12 includes a mounting frame 121, which is connected to the bottom of the movable tension steel beam 8. Multiple rolling wheels 122 are rotatably connected to both sides of the mounting frame 121, and the rolling wheels 122 are in contact with the top surface of the bottom support 13.

[0087] In this technical solution, the sliding component 12 is used to make the position of the tensioned steel beam 8 movable.

[0088] Both the fixed tensioning steel beam 7 and the movable tensioning steel beam 8 are provided with multiple tensioning holes. The reinforcing steel body 1 passes through the tensioning holes through the fixed tensioning steel beam 7 and the movable tensioning steel beam 8 respectively. A plug 14 is provided on one side of both the fixed tensioning steel beam 7 and the movable tensioning steel beam 8. The plug 14 is detachably connected to the surface of the reinforcing steel body 1.

[0089] In this technical solution, the plug 14 can be used to tension the reinforcing steel 1.

[0090] In use, the reinforcing bar 1 passes through the tensioning holes opened in the fixed tensioning steel beam 7 and the movable tensioning steel beam 8, and then the plug 14 is installed. Then, the tensioning equipment 10 can drive the movable tensioning steel beam 8 to move. At this time, the movable tensioning steel beam 8 can drive the mounting frame 121 to move in the same direction, which in turn can drive the rolling wheel 122 to roll on the top surface of the bottom support 13, so that the position of the movable tensioning steel beam 8 can be adjusted, thereby using the movable tensioning steel beam 8 to tension the reinforcing bar 1.

[0091] Both the mold unit and the tensioning unit are equipped with lifting rings.

[0092] In this technical solution, lifting rings can be used to easily lift the mold unit and the tensioning unit.

[0093] During the production of prestressed roof slabs, lifting equipment, such as gantry cranes, can be used to connect with the corresponding lifting rings. At this time, the lifting equipment can be used to lift the mold unit, tensioning unit, and other structures, assemble them, disassemble them, and adjust the position of the mold unit and tensioning unit.

[0094] The tensioning device 10 is a jack or other device with autonomous telescopic function.

[0095] The fixed bracket 11 and the bottom bracket 13 are connected to a plurality of adapting components 15. The adapting components 15 include a reinforcing bracket 151. The inner side of the reinforcing bracket 151 is connected to a plurality of fixed posts 152. The surface of the fixed posts 152 is slidably connected to two symmetrically distributed sliding plates 153.

[0096] The top of the sliding plate 153 is connected to a step block 154. The cross section of the step block 154 is a step-shaped structure, and the top surface of the step block 154 is a rack-shaped structure. An anti-deviation rack 155 is provided above the step block 154. The anti-deviation racks 155 at different positions are respectively connected to the bottom of the bottom bracket 13 and the bottom of the fixed bracket 11.

[0097] Adjacent reinforcing brackets 151 are connected by a plurality of reinforcing connectors 16.

[0098] In use, depending on the required height of the prestressed top slab mold, the bottom support 13, fixed support 11, and movable tensioning steel beam 8 can be moved upward using jacks or other structures. Then, the sliding plate 153 is slid along the fixed column 152, which can drive the step blocks 154 to move in the same direction, so that the corresponding heights of the step blocks 154 on both sides are at the bottom of the fixed support 11 and the tensioning device 10. Then, the fixed support 11 and the bottom support 13 are released. At this time, the fixed support 11 and the bottom support 13 are in contact with the top of the step blocks 154. The step blocks 154 provide support for the fixed support 11 and the bottom support 13, thereby adjusting the height of the movable tensioning steel beam 8, so that the fixed tensioning steel beam 7 and the movable tensioning steel beam 8 have the same height. At this time, the reinforcing bars 1 at different heights can be tensioned.

[0099] When the step block 154 contacts the bottom of the bottom support 13 or the bottom of the fixed support 11, the step block 154 and the anti-deviation rack 155 can position the lateral position of the bottom support 13 and the fixed support 11, thereby increasing the stability of the fixed support 11 and the bottom support 13 and other structures.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
