Description

Technical Field

[0001] This utility model relates to the field of precast component technology, and in particular to a precast platform formwork device for short T-beam components. Background Technology

[0002] The precast concrete components of short T-beams are characterized by being thicker at the top and bottom and thinner in the middle. Because their length ranges from 6 to 15 meters, they cannot be cast vertically along their length. While they can be cast horizontally, these short T-beams are 2 to 3 meters tall, and with the addition of the formwork, their length reaches 5 to 6 meters, significantly occupying production space. Even after precasting, transporting them to the curing kiln for shaping is quite cumbersome. Therefore, the applicant has designed a trolley mold specifically for short T-beam components to facilitate casting and transportation. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabrication device for low T-beam components using a table formwork, so as to solve the problems encountered in the above-mentioned background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A prefabrication device for a low T-beam component includes a platform, a bottom mold, and side molds. Lifting devices are provided on both sides of the bottom of the platform, the bottom mold is installed in the middle of the top of the platform, an anti-arch adjustment device is installed at the bottom of the bottom mold, and tensioning devices are installed on both sides of the top of the platform. The tensioning devices are connected to the side molds in a horizontal transmission direction.

[0006] The lifting device is any one of a pneumatic cylinder, hydraulic cylinder, or electric cylinder; the stretching device is any one of a pneumatic cylinder, hydraulic cylinder, or electric cylinder; the longitudinal section of the bottom mold is rectangular; and the bottom mold is detachably connected to the platform via an anti-arch adjustment device. As a preferred embodiment, the top side of the side mold is equipped with a baffle flush with the end of the short T-beam component.

[0007] In the above scheme, the side mold includes a fixed mold, an edge mold, a base mold, and a horizontal mold. The fixed mold matches the side of the short T-beam component after it is verticalized. The bottom of the fixed mold is fixedly connected to the base mold, and the top of the fixed mold is connected to the horizontal mold. The outer side of the horizontal mold is fixedly connected to the outer side of the base mold through the edge mold. The ends of the fixed mold, the edge mold, the base mold, and the horizontal mold are connected to each other to form a fixed frame.

[0008] As a preferred embodiment, the sides of multiple shaping frames are fixedly connected by square tubes, and each shaping frame has a supporting rib fixed inside. The top of the shaping mold is rotatably connected to the horizontal mold via a pivot, and the tube body of the side mold has a clearance groove. The clearance groove has a flared structure, and a plug is installed inside the clearance groove.

[0009] Compared with existing technologies, the advantages of this invention are as follows: By installing an anti-arch adjustment device at the bottom of the base mold, the anti-arch adjustment device can adjust the height of the short T-beams in the longitudinal direction. Tensioning devices are installed on both sides of the top of the platform, and these devices are horizontally connected to the side molds, allowing for left and right adjustment of the tensioning dimensions according to the width of the short T-beam components. This platform mold prefabrication device can not only produce short T-beam components through casting but also facilitates the subsequent demolding process, possessing high practical value.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a prefabrication device for a low T-beam component includes a platform 1, a bottom mold 2, and side molds 3. Lifting devices 11 are provided on both sides of the bottom of the platform 1. The lifting devices 11 can be any one of a pneumatic cylinder, hydraulic cylinder, or electric cylinder, used to raise the platform 1. The top of the platform 1 and the lifting devices 11 are in contact connection. Automatic lifting and adjustment can be achieved with a PLC to ensure the platform 1 is stably placed on a transfer trolley 4.

[0026] A bottom mold 2 is installed at the top center of the platform 1, and an anti-arch adjustment device 21 is installed at the bottom of the bottom mold 2. The anti-arch adjustment device 21 is designed to achieve height adjustment, thereby improving the utilization rate of this platform mold prefabrication device. The structure of the anti-arch adjustment device 21 can be made according to the technical solution disclosed in the Chinese patent application No. 2022222799312 of a utility model patent applied for by China Railway Third Bureau Group Guangdong Construction Engineering Co., Ltd. on August 29, 2022.

[0027] The longitudinal section of the bottom mold 2 is rectangular, and a long rectangular steel pipe can be used instead. The bottom mold 2 is installed with bolts through the anti-arch adjustment device 21 and is detachably connected to the platform 1, and its height can be adjusted by turning the screws.

[0028] Tensioning devices 31 are installed on both sides of the top of the platform 1. The tensioning devices 31 are connected to the side mold 3 in a horizontal direction. The working end of the tensioning device 31 is fixedly connected to the frame of the side mold 3. During implementation, it can be guided by a slide rail. The tensioning device 31 can be any of a pneumatic cylinder, hydraulic cylinder, or electric cylinder. It can be used with a PLC to achieve automatic tensioning adjustment, such as adjusting the tensioning size left and right according to the width of the short T-beam component.

[0029] As a preferred embodiment, a baffle 32 flush with the end of the short T-beam is installed on the top side of the side formwork 3. The baffle 32 is used to position the steel cage installed on the top of the short T-beam so that the central axis of the steel cage coincides with the central axis of the short T-beam during pouring.

[0030] For implementation, please refer to Figure 6 The side mold 3 includes a shaping mold 34, an edge mold 35, a base mold 36, and a horizontal mold 37. The shaping mold 34 matches the side of the short T-beam component after it is verticalized, tilting to avoid the top and bottom of the short T-beam component and abutting against the middle of the short T-beam component. The bottom of the shaping mold 34 is fixedly connected to the base mold 36, and the top of the shaping mold 34 is fixedly connected to the horizontal mold 37. The outer side of the horizontal mold 37 is fixedly connected to the outer side of the base mold 36 through the edge mold 35. The ends of the shaping mold 34, edge mold 35, base mold 36, and horizontal mold 37 are interconnected to form a shaping frame. The integral shaping frame facilitates the horizontal movement of the tensioning device 31.

[0031] During implementation, end molds are also included to fix the front and rear ends between the two fixed frames, so that concrete can be injected into the enclosed cavity to solidify the short T-beam component and the steel cage into one piece.

[0032] Please see Figure 10 As a preferred embodiment, the sides of multiple shaping frames are fixedly connected by square tubes 33 to form an integral structure, while the tensioning device 31 is evenly installed on each side of the platform 1 as needed. Each shaping frame has a supporting rib 30 fixed inside to support the internal structure of the shaping frame and maintain the structural stability of the shaping frame, so that it can stably shape the short T-beam concrete component after assembly.

[0033] In implementation, such as Figures 1 to 4 As shown, Figure 1 First, place the short T-beam components onto the bottom mold 2. Figure 2 This is a structural diagram of the present invention during the final shaping process. The side molds 3 on both sides are brought closer to the middle by the tensioning device 31, and the steel cage is fixed on the top of the short T-beam component. Figure 3 This is a structural diagram of the present invention during the pouring process, showing concrete being poured at the top to fill the entire cavity. Figure 4The diagram shows the structure of this utility model during transfer. The lifting device 11 raises the platform 1, and the transfer trolley 4 is transported to the bottom of the platform 1 via the track 12. Then, the lifting device 11 lowers a certain distance, and the top of the transfer trolley 4 presses against the platform 1, transporting the platform 1 together with the poured concrete components to the curing kiln for moisturizing and shaping curing.

[0034] Example 2, please refer to Figure 5 and Figure 6 Unlike Embodiment 1, the top of the shaping mold 34 is rotatably connected to the horizontal mold 37 via a rotating shaft 38, and the side mold 35 has a clearance groove on its tube body to provide space for the rotation of the horizontal mold 37. The horizontal mold 37 can rotate along its axial direction to facilitate demolding of the bottom two sides of the reinforcing cage. Then, the side mold 3 is pulled away by the tensioning device 31 to demold the two sides of the precast component.

[0035] As a preferred embodiment, the clearance groove has a funnel-shaped structure, and a plug 39 is installed inside the clearance groove. The plug 39 has a conical structure, with fixing plates installed on both sides. When the precast component is shaped, the plug 39 is installed in the clearance groove, and the fixing plates on both sides of the clearance groove support the side mold 35. When demolding is required, the plug 39 is removed from the clearance groove, and then the horizontal mold 37 is rotatably connected to the shaping mold 34 via the rotating shaft 38. The horizontal mold 37 is pressed down to realize the upper demolding process of the precast component, so as to facilitate the separation of the precast device and the short T-beam component.

[0036] In this embodiment, Figure 7 This is a schematic diagram of the structure of the present invention during casting in Embodiment 2. Figure 8 This is a schematic diagram of the horizontal mold during demolding in Embodiment 2 of this utility model. First, the plug 39 is removed from the clearance groove. Figure 9 This is a schematic diagram of the structure of the preformed frame during demolding in Embodiment 2 of this utility model. After the horizontal mold 37 is pressed down, the side mold 3 is pulled away by the tensioning device 31 to complete the demolding work on both sides of the precast component.
