Description

Technical Field

[0001] This utility model relates to the field of box girder forming technology, specifically a positioning device for an inner mold hoisting hole mold. Background Technology

[0002] During the construction of high-speed railway box girders, after the end formwork and inner formwork are installed, the hoisting hole molds also need to be installed. This involves connecting the bottom of each hoisting hole mold to the panel on the inner formwork using bolts to form a whole, ensuring the stability of the hoisting hole molds. Furthermore, the top of each hoisting hole mold is connected to a rectangular frame that serves as a hoisting hole positioning device, thus linking multiple hoisting hole molds together to limit the lateral and longitudinal sway of individual hoisting hole molds and ensure positioning accuracy.

[0003] While existing hoisting hole positioning devices connect multiple hoisting hole molds into a single unit, the device itself lacks a support point for load-bearing. This makes it susceptible to lateral forces from concrete during construction, or the molds may tilt due to loose bottom nuts, affecting the forming effect of the hoisting holes. Furthermore, connecting the bottom nuts of the hoisting hole molds is complex during construction, and situations where the nuts are not connected may occur. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a positioning device for an inner mold lifting hole mold. It extends the existing lifting hole positioning device by setting an end mold connecting mechanism to connect the end mold, so that the positioning device, the lifting hole mold, and the end mold form an integral whole, thereby effectively ensuring the positioning stability of the lifting hole mold.

[0005] To achieve the above objectives, this utility model provides a positioning device for an inner mold hoisting hole mold, comprising a frame body, wherein the frame body is provided with a plurality of hoisting hole positioning mechanisms capable of connecting the hoisting hole mold, and the frame body is provided with an end mold connecting mechanism; The end mold connection mechanism includes a connecting part and a fixing part. The frame body is fixedly connected to the connecting part, and the connecting part and the fixing part are detachably connected. The fixing part is provided with an installation structure for fixedly connecting to the end mold.

[0006] In one embodiment, one of the connecting part and the fixing part is an assembly plate, and the other is an assembly column; The assembly plate has a first through hole, and the assembly column passes through the first through hole and is fixedly connected to the assembly plate.

[0007] In one embodiment, a vertical plate is fixedly provided on the assembly plate, and an abutment is provided on the vertical plate for pressing against the side of the assembly column.

[0008] In one embodiment, the abutting member includes a first screw and a first nut, and a second through hole is provided on the upright plate; The nut of the first screw is located on the outside of the upright plate, the shank of the first screw passes through the second through hole and abuts against the side of the assembly column, and the first nut is threaded onto the shank of the first screw and abuts against the inside of the upright plate.

[0009] In one embodiment, there are two upright plates, which are located on both sides of the first through hole, and both upright plates are provided with the abutment member.

[0010] In one embodiment, the first through hole is a strip-shaped hole, and the length direction of the first through hole is parallel to the spacing direction of the two upright plates.

[0011] In one embodiment, the assembly post is a screw, and the assembly post is fixedly connected to the assembly plate by a second nut.

[0012] In one embodiment, the number of end-mold connection mechanisms is two or more.

[0013] In one embodiment, the hoisting hole positioning mechanism includes a fixing plate with a third through hole for a fixing screw at the top of the hoisting hole mold to pass through.

[0014] In one embodiment, a support sleeve is fixedly connected to the bottom of the fixing plate, and the third through hole communicates with the top of the support sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: 1. This utility model connects the end mold by setting an end mold connecting mechanism, so that the positioning device, the hoisting hole mold and the end mold form a whole, thereby ensuring the positioning stability of the hoisting hole mold and effectively preventing the hoisting hole mold from shifting during construction; 2. In the preferred embodiment of this utility model, the first through hole is set as a strip hole, and the assembly column is fixed by two sets of abutment parts. This allows the positioning device, the frame body and the connecting part to move along the length direction of the first through hole within the allowable error range, thereby solving the problem that the positioning device and the end mold cannot be connected due to errors in actual on-site construction. 3. In the preferred embodiment of this utility model, a third through hole is provided on the fixed plate, through which the top screw of the lifting hole mold can pass. That is, during the application process, the top of the lifting hole mold is connected and fixed to the fixed plate by bolts. This means that the bottom of the lifting hole mold only needs to be provided with a vertical rod that is inserted and matched with the panel on the inner mold. Therefore, it is not necessary to manually enter the inner mold to install the fastening nut at the bottom of the lifting hole mold, which can effectively save labor costs and improve construction efficiency.

[0025] like Figures 1 to 3 The diagram shows a positioning device (hereinafter referred to as "positioning device") for an inner mold hoisting hole mold disclosed in this embodiment. It mainly includes a frame body 1, on which multiple hoisting hole positioning mechanisms capable of connecting to the hoisting hole mold 2 are provided. The frame body 1 also has at least one end mold connecting mechanism. Specifically, the frame body 1 can be a rectangular frame formed by welding multiple profiles in a crisscross pattern. The end mold connecting mechanism includes a connecting part and a fixing part. The frame body 1 is fixedly connected to the connecting part, and the connecting part and the fixing part are detachably connected via an assembly component. The fixing part is provided with an installation structure for fixedly connecting to the end mold 3. By setting the end mold connecting mechanism to connect the end mold 3, the positioning device, the hoisting hole mold 2, and the end mold 3 form a whole, thereby ensuring the positioning stability of the hoisting hole mold 2 and effectively preventing displacement of the hoisting hole mold 2 during construction.

[0026] In this embodiment, one of the connecting part and the fixing part is an assembly plate 4, and the other is an assembly column 5. The assembly plate 4 is provided with a first through hole 401, and the assembly column 5 passes through the first through hole 401 and is fixedly connected to the assembly plate 4.

[0027] refer to Figure 4In this embodiment, the assembly plate 4 is the connecting part, and the assembly column 5 is the fixing part. Specifically, the frame body 1 has a connecting rod 101 extending towards the end mold 3 at the position where the end mold connecting mechanism is located. The assembly plate 4 is welded or fixed to the connecting rod 101 by bolts. The installation structure can be a connecting plate 501 welded to the bottom end of the assembly column 5, and then fixed to the end mold 3 by welding or bolts. Alternatively, the bottom end of the assembly column 5 can be directly set as a screw structure, and a threaded hole can be opened on the end mold 3, and then the assembly column 5 can be threadedly connected to the end mold 3.

[0028] In the specific implementation process, a vertical plate 6 is fixedly welded onto the assembly plate 4, and the vertical plate 6 is provided with an abutment member for pressing against the side of the assembly column 5, thereby connecting and fixing the assembly plate 4 and the assembly column 5. Specifically, the abutment member includes a first screw 7 and a first nut 8. A second through hole 601 is opened on the vertical plate 6. The nut of the first screw 7 is located on the outside of the vertical plate 6, and the screw shank of the first screw 7 passes through the second through hole 601 and abuts against the side of the assembly column 5. The first nut 8 is threaded onto the screw shank of the first screw 7 and abuts against the inside of the vertical plate 6. In specific applications, a telescopic structure such as a hydraulic cylinder or pneumatic cylinder can also be directly arranged on the vertical plate 6 as the abutment member.

[0029] In a preferred embodiment, there are two upright plates 6, located on either side of the first through hole 401. Each upright plate 6 has abutment members to press the assembly column 5 against both sides, thus ensuring the stability of the connection between the assembly column 5 and the assembly plate 4. More preferably, the first through hole 401 is a strip-shaped hole, and its length is parallel to the spacing direction of the two upright plates 6. By adjusting the depth of the two sets of abutment members passing through the second through hole 601, the position of the assembly column 5 within the first through hole 401 can be adjusted. This allows the positioning device, the frame body 1, and the connecting part to move along the length of the first through hole 401 within an allowable error range, thereby solving the problem of the positioning device failing to connect with the end mold 3 due to errors during actual on-site construction.

[0030] It is worth noting that in specific applications, the assembly plate 4 and the assembly column 5 are not limited to being connected and fixed by an abutment. The assembly column 5 can also be directly set as a stud, and after the assembly column 5 passes through the second through hole 601, a second nut is threaded onto the assembly column 5, and the assembly plate 4 is fixed to the end mold 3 or the frame body 1 using the second nut. For example, when the assembly column 5 is a fixed part, the assembly plate 4 is fixedly clamped between the second nut and the end mold 3 under the cooperation of the second nut and the assembly column 5, thereby achieving a fixed connection between the assembly plate 4 and the assembly column 5. When the assembly column 5 is a connecting part, the assembly plate 4 is fixedly clamped between the second nut and the frame body 1 under the cooperation of the second nut and the assembly column 5, which also achieves a fixed connection between the assembly plate 4 and the assembly column 5.

[0031] In a preferred embodiment, the number of end mold connecting mechanisms is set to two or more, so that the positioning device is connected to the end mold 3 through multiple fulcrums, thereby improving the connection stability of the positioning device. It is worth noting that in specific applications, the number of end mold connecting mechanisms can also be set to one. In this case, the connecting rod 101 can be positioned in the middle of the frame body 1, i.e. Figure 5 As shown.

[0032] In practical applications, the assembly plate 4 can be set as a fixing part, and the assembly column 5 can be set as a connecting part. In this case, the assembly column 5 can be directly welded to the connecting rod 101, or the assembly column 5 can be welded to the connecting rod 101 through a transfer plate. The bottom of the assembly plate 4 can be welded to the upright plate 6, and the upright plate 6 can be welded or bolted to the end mold 3. At the same time, the upright plate 6 also serves as the function of installing the abutment part.

[0033] refer to Figure 6 The hoisting hole positioning mechanism includes a fixing plate 9, which is welded or bolted to the frame body 1. The fixing plate 9 has a third through hole 901 for the fixing screw 201 at the top of the hoisting hole mold 2 to pass through. During connection, the fixing screw 201 at the top of the hoisting hole mold 2 is connected and fixed to the fixing plate 9 using bolts. This allows the bottom of the hoisting hole mold 2 to only require a vertical rod 202 to be inserted and engaged with the panel on the inner mold 11, eliminating the need for manual entry into the inner mold to install the fastening nut at the bottom of the hoisting hole mold 2. This effectively saves labor costs and improves construction efficiency.

[0034] In a preferred embodiment, a support sleeve 10 is fixedly connected to the bottom of the fixing plate 9, and the third through hole 901 communicates with the top end of the support sleeve 10. During connection, the fixing screw 201 at the top end of the lifting hole mold 2 passes through the support sleeve 10 and the third through hole 901 in sequence, and after the fixing screw 201 at the top end of the lifting hole mold 2 is fixed to the fixing plate 9 by bolts, the bottom end of the support sleeve 10 is supported on the top of the lifting hole mold 2.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
