Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, and in particular to a precast component casting mold. Background Technology

[0002] Traditional bridge deck facilities employ on-site simply supported box girder cast-in-place concrete construction techniques, which primarily rely on direct concrete pouring operations on bridge pier tops or temporary supports. This process involves constructing a formwork support system at the construction site, completing the reinforcement cage binding, and then using commercial concrete or on-site mixed materials for layered pouring to ultimately form a continuous bridge deck structure.

[0003] However, the construction cycle of traditional cast-in-place bridge decks is long. On-site formwork, reinforcement binding, and pouring require a lot of time. They are easily affected by weather and traffic. Open-air operations are affected by climate and are prone to defects such as cracks and honeycombing. They also have problems such as high noise, heavy dust pollution, and high material waste rate.

[0004] With the deepening of the concept of green railway construction, the industry has put forward higher requirements for the environmental performance of construction. In order to minimize the disturbance of on-site operations to the surrounding environment and reduce resource and energy consumption, the technical demand for prefabricated bridge deck facilities has emerged. Therefore, it is necessary to design a user-friendly prefabricated concrete mold for bridge decks to meet the needs of prefabricated concrete bridge deck components. Utility Model Content

[0037] Example 1

[0038] like Figure 1-5 As shown, a precast component casting mold includes: a bottom mold 1, a side mold 2, an end mold 3, a connecting device 4, and an opening and closing device 5. The bottom mold 1 is mounted on a frame 6. The side mold 2 is hinged to the front and rear sides of the bottom mold 1, and the end mold 3 is hinged to the left and right end faces of the end mold 3. The connecting device 4 detachably connects the side mold 2 to the bottom mold 1, detachably connects the end mold 3 to the bottom mold 1, and detachably connects the side mold 2 to the end mold 3. The side mold 2 and the end mold 3 are each equipped with the opening and closing device 5, which is used to control the opening or closing of the side mold 2 and the end mold 3.

[0039] Specifically, the bottom mold 1, side mold 2, and end mold 3 are used to match the surface shape of the precast component with the shape of the precast component.

[0040] Specifically, such as Figure 1 As shown, the precast component casting mold also includes a hinge device 7, which is disposed between the side mold 2 and the bottom mold 1, and between the end mold 3 and the bottom mold 1.

[0041] Specifically, such as Figure 6 As shown, the hinge device 7 includes: a first connecting seat 701, a second connecting seat 702, a shaft 703, a bushing 704, and a positioning plate 705. The frame 6 is equipped with the first connecting seat 701 for the end mold 3 and the side mold 2. The end mold 3 and the side mold 2 are connected to the second connecting seat 702 for the first connecting seat 701. The bushing 704 is connected to the second connecting seat 702. The shaft 703 is inserted into the bushing 704 and the first connecting seat 701. A positioning groove is opened on the outer periphery of the shaft 703. The positioning plate 705 is inserted into the positioning groove and welded to the adjacent bushing 704. The positioning plate 705 limits the axial position of the shaft 703. The first connecting seat 701 is rotatably fitted onto the middle of the shaft 703. The hinge device 7 realizes the hinge function between the components.

[0042] Specifically, such as Figure 7 , 8 As shown, the connecting device 4 includes: a connector 401, a locking member 402, and an anti-drop member 403. The side mold 2 and the end mold 3 are both equipped with the anti-drop member 403. Part of the connector 401 passes through the side mold 2, the bottom mold 1, and the corresponding anti-drop member 403 and is connected to the corresponding locking member 402. Part of the connector 401 passes through the end mold 3, the bottom mold 1, and the corresponding anti-drop member 403 and is connected to the corresponding locking member 402. The remaining part of the connector 401 passes through the side mold 2, the end mold 3, and the corresponding anti-drop member 403 and is connected to the corresponding locking member 402. The connector 401 and the locking member 402 respectively realize the connection between the side mold 2 and the bottom mold 1, the end mold 3 and the bottom mold 1, and the side mold 2 and the end mold 3. When the end mold 3 and the side mold 2 are opened, the anti-drop member 403 prevents the connector 401 from falling off.

[0043] Specifically, such as Figure 7 , 8 As shown, the connecting part 401 is a bolt, and a limiting sleeve 404 is fitted around the outer periphery of the bolt. The locking part 402 is a nut, which is welded to the corresponding bottom mold 1 or end mold 3. The anti-drop part 403 is welded to the corresponding side mold 2 or end mold 3. The anti-drop part 403 has connecting plates on both sides, and a limiting plate is set between the connecting plates. The limiting plate has a limiting hole 405, which is a structure of small and large holes, that is, it includes a small hole with a smaller diameter and a large hole with a larger diameter. The large hole is above the small hole and they are interconnected. The diameter of the large hole is larger than the diameter of the limiting sleeve 404, and the diameter of the small hole is smaller than the diameter of the limiting sleeve 404. The limiting sleeve 404 passes through the large hole, and the bolt falls into the small hole under its own weight. The limiting plate limits the limiting sleeve 404, so that when the bolt and nut are separated, the bolt can continue to be connected to the side mold 2 or end mold 3.

[0044] Specifically, such as Figure 9As shown, the opening and closing device 5 includes: a driving member 501, a first driven member 502, and a second driven member 503. The driving member 501 is rotatably disposed on one side of the side mold 2 or the end mold 3. One end of the first driven member 502 is rotatably connected to the corresponding driving member 501, and the other end is rotatably connected to the corresponding side mold 2 or the end mold 3. One end of the second driven member 503 is hinged to the first driven member 502, and the other end is hinged to the corresponding side mold 2 or the end mold 3. By rotating the driving member 501, the first driven member 502 and the second driven member 503 transmit the external force of the driving member 501 to the side mold 2 or the end mold 3, thereby controlling the opening and closing of the side mold 2 or the end mold 3.

[0045] Specifically, such as Figure 9 As shown, the driving component 501 is a driving rod with an assist rod at its upper end. The assist rod extends the lever arm length for driving the side mold 2 or end mold 3. A base is mounted on the frame 6, and the lower end of the driving rod is hinged to the base. The first driven component 502 is a driven rod with its lower end hinged to the driving rod and its upper end hinged to the mounting seat of the side mold 2 or end mold 3. The second driven component 503 is a tension spring with its lower end hinged to the corresponding side mold 2 or end mold 3 and its upper end hinged to the rod body of the driven rod. The tension spring can both drive the side mold 2 or end mold 3 and provide a buffer.

[0046] When using this type of precast component casting mold, pushing the drive rod causes the side mold 2 and end mold 3 to close. Connecting the connector 401 to the locking member 402 connects the side mold 2, end mold 3, and bottom mold 1 into an integral structure. The interior of this integral structure is the forming zone. After placing the reinforcing cage in the forming zone and casting, the connector 401 is unlocked from the locking member 402, and the drive rod is pulled to open the side mold 2 and end mold 3. The connecting device 4 achieves a stable and detachable connection between the bottom mold 1, side mold 2, and end mold 3, while the opening and closing device 5 enables the rapid opening or closing of the side mold 2 and end mold 3, thus giving this type of bridge deck precast component good usability.

[0047] Example 2

[0048] Based on Example 1, such as Figure 1 , 10 As shown, the precast component casting mold also includes a positioning device 8, which is disposed between the end mold 3 and the side mold 2. The positioning device 8 is also disposed between the end mold 3 and the bottom mold 1 or between the side mold 2 and the bottom mold 1. The positioning device 8 improves the accuracy of positioning between components.

[0049] Specifically, taking the positioning device 8 set between the end mold 3 and the side mold 2, and between the end mold 3 and the bottom mold 1 as an example, the positioning device 8 is a conical positioning structure. The positioning device 8 includes: a positioning pin 801 and a positioning sleeve 802. The end mold 3 and the bottom mold 1 are both equipped with positioning sleeves 802. The positioning sleeves 802 have conical holes. The positioning pin 801 has a conical positioning end. The positioning pin 801 is connected to the side mold 2 or the end mold 3. When the side mold 2 and the end mold 3 are closed, the positioning pin 801 of the side mold 2 is inserted into the positioning sleeve 802 of the end mold 3, and the positioning pin 801 of the end mold 3 is inserted into the positioning sleeve 802 of the bottom mold 1. Through the self-centering characteristic of the conical positioning structure, the stability and accuracy of the positioning between the end mold 3, the side mold 2, and the bottom mold 1 are improved.

[0050] Example 3

[0051] Based on any of the foregoing embodiments, such as Figure 11 As shown, the precast component casting mold also includes a sealing element 9, which is provided between the side mold 2 and the end mold 3, between the side mold 2 and the bottom mold 1, and between the end mold 3 and the bottom mold 1.

[0052] Specifically, the sealing element 9 uses a sealing strip. The contact surfaces of the end mold 3, side mold 2, and bottom mold 1 are all flat, rigid contact structures, and each contact surface is equipped with at least one sealing strip. Taking the bottom mold 1 as an example, a groove is set on the bottom mold 1, and the sealing strip is inserted into the groove, so that part of the sealing strip protrudes from the groove and contacts the end mold 3 and side mold 2 when the mold is closed, thereby forming a sealing structure. Alternatively, the sealing strip can be directly bonded to the bottom mold 1, side mold 2, and end mold 3 to form a good sealing structure.

[0053] Example 4

[0054] Based on any of the foregoing embodiments, such as Figure 5 As shown, the precast component casting mold also includes a lifting device 10, the lifting end of which is disposed in the bottom mold 1, and the lifting device 10 is used to lift the precast component.

[0055] Specifically, the lifting device 10 is a cylindrical tubular structure. The frame 6 is equipped with a plate, and the lifting device 10 is vertically slidably inserted into the plate. The upper end of the lifting device 10 is inserted into the lifting hole opened in the bottom mold 1. A linear drive device, such as a hydraulic cylinder, is installed below the lifting device 10. The piston rod of the hydraulic cylinder is set upward and connected to the lifting device 10. When casting the precast component, the head of the lifting device 10 is in the lifting hole. When the precast component is demolded, the hydraulic cylinder drives the lifting device 10 to move upward a certain distance, cooperating with external lifting devices (such as cranes, overhead cranes, etc.) to remove the precast component from the mold. It should be noted that the head of the lifting device 10 is slidably inserted into the lifting hole, which inevitably creates a small gap between the lifting hole and the head structure. During the casting process, there may be some water seepage at the lifting hole, but this does not affect the molding operation of the precast component.
