Description

Technical Field

[0001] The utility model relates to the technical field of beam body prefabrication moulds, in particular to a demoulding connection device for side moulds and end moulds and a box beam mould. Background Art

[0002] When pouring the formwork, a connecting structure is required to tightly connect the end formwork and the side formwork to prevent leakage during pouring. After the beam body is poured and cured to reach the demoulding strength, the restrictions of the connecting parts are removed, and then various demoulding methods are used to demould the formwork.

[0003] On the one hand, when pouring small box girders, the length of the small box girders varies a lot, and the relative position of the end form and the side form is not fixed, so the connection structure needs to be adjustable. The connection structure currently used is mostly screws. Although its length is adjustable, the screws are compressed during the pouring process, which makes the screws themselves unstable and easily deformed, thus affecting the beam forming effect.

[0004] On the other hand, in order to save costs, the end form is often separated from the box beam by hammering or crowbars. However, this method causes the box beam to be subjected to excessive external impact or extrusion force, which can easily cause large areas of concrete to fall off at the end of the box beam, thus requiring the box beam to be repaired again, reducing work efficiency and affecting the appearance of the beam. In addition, since obstacles such as rubber extraction rods and bellows are installed at the end form, it is easy to hinder the installation and disassembly of the end form demoulding device and the working process, affecting construction efficiency.

[0018] In one embodiment, the connecting rod (2) and the end mold (10) are fixed by welding, bolting, pinning or integrally formed, and the connecting rod (2) is a hollow steel pipe or a hollow screw.

[0019] In one embodiment, the connecting rod (2) is fixed to the connecting seat (1) by threaded connection or by connecting and fixing via a pin (3), and the position of the connecting rod (2) relative to the connecting seat (1) is adjustable.

[0025] 1. The demoulding connection device in the utility model can be installed at the connection between the end mold and the side mold during the process of connecting the end mold and the side mold, so as to avoid conflicts with the prefabricated beam body and the extraction rod at the outer side of the end mold, so that other parts do not need to be disassembled during demoulding, which reduces the process and saves working hours.

[0043] Example 1

[0044] like Figure 1 , Figure 2 The figure shows a demoulding connection device for a side mold and an end mold (hereinafter referred to as "demolding connection device") disclosed in this embodiment, which mainly includes a demoulding mechanism 6 and a connection mechanism. The connection mechanism is detachably connected between the side mold 9 and the end mold 10, and is mainly used to fix and support the end mold 10. The demoulding mechanism 6 is arranged on the side mold 9, and the demoulding mechanism 6 has a push piece 7 that can be displaced along the length direction of the side mold 9 to push the end mold 10 to achieve automatic demoulding.

[0045] The demoulding connection device in this embodiment can be installed at the connection between the end mold 10 and the side mold 9 during the process of connecting the end mold 10 and the side mold 9, thereby avoiding conflicts with the prefabricated beam body and the extraction rods on the outside of the end mold 10, and then there is no need to disassemble other parts during demoulding, which can reduce the process and save work hours. At the same time, the end mold 10 can be automatically demoulded through the push piece 7 on the demoulding mechanism 6, so that the demoulding connection device integrates the demoulding and connection functions, thereby effectively saving costs.

[0046] In this embodiment, the connecting mechanism includes a connecting seat 1 and a connecting rod 2. The first end of the connecting seat 1 is provided with a first connecting structure for fixing the connecting seat 1 on the side mold 9. The first end of the connecting rod 2 is provided with a second connecting structure for fixing the connecting rod 2 on the end mold 10. The second end of the connecting seat 1 is detachably connected to the second end of the connecting rod 2. Specifically, the connecting rod 2 and the end mold 10 are welded, bolted, pinned or integrally formed, and the connecting rod 2 adopts a hollow steel pipe or a hollow screw, so that it has the advantages of light weight and good stability. Among them, the connecting rod 2 is threadedly connected and fixed to the connecting seat 1 or connected and fixed by a pin shaft 3, and the position of the connecting rod 2 relative to the connecting seat 1 is adjustable, so as to meet the position change of the end mold 10 on the side mold 9, so that the side mold 9 and the end mold 10 can be suitable for beam body forming with various beam length changes.

[0047] In the specific implementation process, the connection seat 1 is provided with at least one first through hole group in the length direction of the side mold 9, and the connection rod 2 is provided with at least one second through hole group in the length direction of the side mold 9, and the first through hole group and the second through hole group are not 1 at the same time. In the width direction of the side mold 9, the first through hole group includes at least one first through hole, and the second through hole group includes at least one second through hole 4. The connection seat 1 and the connection rod 2 are connected and fixed by at least two pins 3 that cooperate with the first through hole and the second through hole 4. Therefore, when connecting the connection seat 1 and the connection rod 2, the first through hole and the second through hole 4 at different positions can be selected by the pin 3 for fixing, so that the relative position of the connection seat 1 and the connection rod 2 can be adjusted, thereby realizing the relative position of the end mold 10 and the side mold 9. Among them, the pin 3 can also be replaced by a bolt or other fixing structure.

[0048] As a preferred embodiment, in the width direction of the side mold 9, the first through hole group includes more than two first through holes, and the second through hole group includes more than two second through holes 4, that is, the connecting seat 1 and the connecting rod 2 are connected by the array-distributed through holes and the matching pins 3, thereby improving the bearing capacity of the demolding connection device and providing reliable support for the end mold 10.

[0049] It is worth noting that in the specific application process, the connection seat 1 and the connection rod 2 are not limited to the through-hole fixing form shown in the figure, and a quick release mechanism such as a buckle can also be used. For example, a card slot distributed in an array is set at the second end of the connection seat 1, and a card block distributed in an array is set at the second end of the connection rod 2. At the same time, the hinge structure is used to make the second end of the connection rod 2 flippable, so that part or all of the card block can be embedded in the card slot, thereby achieving the relative position adjustment of the end mold 10 and the side mold 9.

[0050] In the specific implementation process, the second end of the connecting seat 1 can be set to a block structure or a hollow tubular structure, and the second end of the connecting rod 2 can be set to a corresponding slot. When connected, the second end of the connecting seat 1 is embedded in the slot and then connected to the connecting rod 2 through the pin 3. Alternatively, the second end of the connecting rod 2 can be set to a block structure or a hollow tubular structure, and the second end of the connecting seat 1 can be set to a slot. When connected, the second end of the connecting rod 2 is embedded in the slot and then connected to the connecting seat 1 through the pin 3. It is also possible to set the connecting seat 1 and the connecting rod 2 to a plate or block structure, and fix the connecting seat 1 and the connecting rod 2 by fastener 3 after stacking.

[0051] In this embodiment, a connecting plate 5 is provided at the first end of the connecting seat 1, and the first connecting structure is a bolt pair provided between the connecting plate 5 and the end rib plate of the side mold 9. Alternatively, the connecting plate 5 can be directly welded to the end rib plate of the side mold 9.

[0052] In the specific implementation process, a through hole for the push piece 7 to pass through is provided on the end rib plate of the side mold 9 at the position corresponding to the connection seat 1, so that the connection plate 5 is located on the displacement path of the push piece 7, or the connection plate 5 can be directly connected and fixed to the push piece 7. During the casting process, the connection plate 5 is fixed to the end rib plate of the side mold 9 by the first connection structure 8; when demoulding is required, the first connection structure 8 is removed to release the connection between the side mold 9 and the end mold 10, and then the push piece 7 on the demoulding mechanism 6 pushes the connection plate 5, so as to achieve the purpose of pushing the end mold 10 away from the side mold 9. Preferably, a push block is provided at the position corresponding to the push piece 7 on the connection plate 5, such as a rubber pad fixed by bolts, so as to avoid deformation and damage of the connection plate 5 during demoulding.

[0053] In the specific implementation process, the demoulding mechanism 6 is an oil cylinder, an air cylinder, an electric push rod or a screw nut pair. For example, when an oil cylinder is used as the demoulding mechanism 6, the push member 7 is the piston rod of the oil cylinder.

[0054] Example 2

[0055] like Figures 5 and 6 The box girder mold disclosed in this embodiment is shown, which mainly includes a side mold 9, an end mold 10 and the demoulding connection device 11 in Example 1. Among them, the first connection structure in the demoulding connection device 11 is connected to the rib plate of the side mold 9, and the second connection structure in the demoulding connection device 11 is connected to the end mold 10. The specific connection method is the same as that in Example 1, so it will not be repeated in this embodiment.

[0056] In the specific implementation process, the number of demoulding connection devices 11 can be set to multiple, so as to provide more uniform support for the end mold 10, make the connection between the end mold 10 and the side mold 9 tighter, avoid leakage of slurry, and provide a more uniform demoulding driving force for the end mold 10, so as to avoid damage to the beam body due to uneven force during the demoulding process.

[0057] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
