Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of formwork making, and particularly relates to a prefabricated component side formwork without closed loop steel bars on the side, a combined structure, a formwork making device and a method. BACKGROUND

[0002] When the prefabricated component is made, a mold frame needs to be assembled first, and then concrete is poured into the mold frame to form a prefabricated component with a corresponding shape and structure.

[0003] The mold frame of the prefabricated component is usually enclosed by a side formwork and a bottom formwork, but in the related art, the assembly of the side formwork of the prefabricated component without steel bars on the side is very inconvenient, which reduces the production efficiency.

[0004] Therefore, the present application is provided. SUMMARY

[0005] The present application aims to provide a prefabricated component side formwork without closed loop steel bars on the side, a combined structure, a formwork making device and a method, so as to realize the rapid assembly and disassembly of the prefabricated component side formwork without steel bars on the side.

[0006] In order to achieve the above-mentioned purpose, the present application provides a prefabricated component side formwork without closed loop steel bars on the side, which comprises an upper plate, a middle plate and a lower plate, at least one side of the middle plate is connected with the upper plate or the lower plate through a rotating shaft to form a rotatable upper plate and / or lower plate, and the assembly state and the disassembly state of the mold are realized through rotation.

[0007] Optionally, the middle plate is further provided with a control mechanism, which can act on the upper plate and / or the lower plate to realize the assembly state and the disassembly state of the mold through rotation.

[0008] Optionally, the two sides of the middle plate are connected with the upper plate and the lower plate through rotating shafts respectively.

[0009] Optionally, the lower plate is connected with the middle plate through a rotating shaft, and the upper plate and the middle plate form an integral structure which cannot rotate relative to each other.

[0010] Optionally, the control mechanism comprises a main shaft arranged along the length direction of the middle plate, and a supporting part is arranged on the main shaft, so that when the supporting part rotates with the main shaft, the upper plate and / or the lower plate is lifted up when the rotatable upper plate and / or lower plate is close to the supporting part, so as to realize the assembly state, and the support of the upper plate and / or the lower plate is released when the rotatable upper plate and / or lower plate is away from the supporting part, so as to realize the disassembly state.

[0011] Optionally, the middle plate is further provided with a reinforcing rib for improving the supporting stability of the supporting part.

[0012] This invention also provides a combined structure, including the aforementioned precast component side mold and bottom mold without closed sleeve reinforcement on the sides, wherein the side mold and the bottom mold are connected by an interlocking structure.

[0013] This invention also provides a formwork erection device, including a mold box, on which the aforementioned precast component side mold without side-enclosed reinforcing bars is provided on the panel of the mold box.

[0014] This invention also provides a method for assembling and disassembling a side mold. In the above-mentioned vertical mold equipment, at least a portion of the side mold is fixed to the panel, so that the assembly and disassembly of the side mold can be completed by switching the assembly state and the disassembly state in the vertical mold; or the side mold can also be disassembled after being removed from the vertical mold equipment along with the mold and the cast precast components.

[0015] The precast component side mold, assembly structure, erection equipment, and method provided by this invention for precast components without side-mounted reinforcing bars have the following beneficial effects: For precast components without side-mounted reinforcing bars, the structure formed by the middle plate, upper plate, and lower plate can be used to close the side of the entire mold frame. At the same time, the upper plate and / or lower plate are connected to the middle plate through a pivot, so the relative position of the upper or lower plate with the middle plate can be changed through the pivot. When the upper and lower plates rotate to a state of mutual parallelism, it means that the side mold has been assembled. When the upper or lower plate rotates towards the inside of the middle plate, a loose structure and state are formed. That is, at this time, the surface of the middle plate moves away from the overall structure of the mold from the side closest to the rotatable upper or lower plate, forming a detachable state relative to the mold as a whole or the cast precast component. The entire assembly and disassembly process does not require splicing the various panels together as in the side mold of precast components with side-mounted reinforcing bars, thus improving production efficiency.

DETAILED DESCRIPTION

[0044] The principles and spirits of the present application will be described below with reference to several exemplary embodiments shown in the drawings. It should be understood that the description of these embodiments is only to enable those skilled in the art to better understand and implement the present application, and does not limit the scope of the present application in any way.

[0045] In the related art, for the prefabricated component with the side steel bars, a segment of the steel bars in the form of arc is used to close the two horizontal steel bars extending out of the side, forming a sleeve steel bar, in order to avoid the sleeve from affecting the assembly of the side mold, a hole for the steel bar to pass through is needed to be reserved on the side mold. Therefore, the inventor develops a combined side mold, which is combined by three parts, and after the combination, the edges of the three panels can be combined into a hole for the side steel bar to pass through, thereby bypassing the obstruction of the arc closed segment of the sleeve steel bar. However, in the prefabricated component without the side steel bars, there is no need to reserve the hole for the steel bar to pass through, and at this time, the combined side mold is used to reduce the production efficiency. Therefore, the embodiment of the present application provides a side mold for the production of the prefabricated component without the side steel bars.

[0046] In combination Figures 1-26 As an embodiment, the side mold 100 includes three main parts of the upper plate 1, the middle plate 2 and the lower plate 3. The upper plate 1 and the lower plate 2 are respectively located on the upper and lower sides of the middle plate 3. In an embodiment, one or more rotating shafts 4 are arranged on the two sides of the middle plate 2, and the upper plate 1 and the lower plate 3 are respectively connected with the middle plate 2 through the rotating shafts. The axis direction of the rotating shaft 4 is parallel to the length direction of the middle plate 2. When the upper plate 1 and the lower plate 3 are both rotated to the outermost side, that is, the state of being parallel to each other, a side mold capable of being used to close the side of the prefabricated component mold is formed. Further, when the upper plate 1 and the lower plate 3 are rotated to the inner side, that is, the direction of being close to the middle part of the middle plate 2, the state of being folded back, at this time, the side of the middle plate 2 is correspondingly raised, the mold is disassembled, and the prefabricated component is taken out. In order to control the rotation of the upper plate 1 and the lower plate 3, a control mechanism is arranged on the middle part of the middle plate 2, and the control mechanism includes a main shaft 5 arranged along the length direction of the middle plate 2 and connected with the middle plate 2 through a base 6. A support part 7 is fixed on the main shaft 5, and in the embodiment, the support part 7 is generally in the form of long, that is, has a long side and a short side. When the rotating direction of the support part 7 is such that the long side of the support part 7 tends to be parallel to the middle plate 2, at this time, the length of the long side can be used to support the upper plate 1 and the lower plate 3 on the two sides to the aforementioned parallel state, that is, the assembly state is realized. Conversely, when the rotating direction of the support part 7 is such that the long side of the support part 7 tends to be perpendicular to the middle plate 2, at this time, the two short sides of the support part 7 are rotated to the position away from the upper plate 1 and the lower plate 3, and the support to the upper plate 1 and the lower plate 3 is released, so that the upper plate 1 and the lower plate 3 can be folded back to the direction of the middle part of the middle plate along the rotating shaft, and the disassembly state is realized.

[0047] In some embodiments, the surface of the short side can be in the form of arc, so that the support action is more smooth.

[0048] Further, the main shaft 5 is provided with a wrench 8 for controlling the rotation of the main shaft 5, which is convenient for control. Optionally, the middle plate 2 is further provided with a reinforcing rib 9 for reinforcing the support to the support part 7.

[0049] In another embodiment, the middle plate 2 can be connected to the rotating shaft 4 on one side only, for example, the lower plate 3 can be connected to the middle plate through the rotating shaft, and the upper plate 1 and the middle plate 2 are integrated. At this time, the support part 7 extends only on the side close to the lower plate 3 and is configured in a long shape. In the connection mode of the rotating shaft 4 on both sides, the rotating degree of freedom is higher, and more space can be left for the groove on the side of the prefabricated component. If the single-sided shaft of the present embodiment is used, it can be used for the production of prefabricated components without grooves.

[0050] As an embodiment, the present application also provides a combined structure, which comprises a side mold 100 and a bottom mold 200, which can be used as part of a prefabricated component mold. The bottom of the side mold 100 and the bottom mold 200 are connected by the interlocking device 10, so that the connection of the two is more firm, at the same time, it is also convenient for the quick disassembly of the side mold 100 and the bottom mold 200, and improves the efficiency of the combined mold. For example, a fixed part 11 is arranged below the bottom mold 200, the interlocking device 10 is arranged at the bottom of the side mold 100 and is detachably connected with the fixed part 11. The interlocking device 10 can adopt any suitable structure, for example, in the present embodiment, it is a spring type interlocking buckle, which is unlocked in the relaxed state and locked in the tension state. The combined mode of the bottom mold 200 and the side mold 100 has many modes, which can be that the bottom end of the side mold 100 abuts against the upper side of the bottom mold 200, or the side edge of the bottom mold 100 abuts against the bottom side of the side mold 200, or other connection modes.

[0051] The prefabricated component mold made of the side mold provided by the embodiment of the present application can be used for the production of the inner partition wall without steel bars on both sides. As described above, the side mold with double rotating shafts, of which the upper plate 1 and the lower plate 3 protrude relative to the end face of the middle plate 2, is used for constructing the groove on the side of the prefabricated component, and is suitable for the production of the inner partition wall 13 with the groove 12. The single-sided rotating shaft is suitable for the production of the inner partition wall 13 without the groove.

[0052] The embodiment of the present application also provides a vertical mold equipment, which comprises a plurality of spaced-apart mold boxes 400, and the prefabricated component mold 300 is arranged between adjacent mold boxes 400. The prefabricated component mold 300 is enclosed by the side mold 100, the bottom mold 200 and the like described above. In an embodiment, the side mold 100 adopts the single-sided shaft connection mode in the above embodiment, that is, the lower plate 3 and the middle plate 2 are connected by the rotating shaft 4, and the upper plate 1 and the middle plate 2 are integrally formed. At this time, the lower plate 3 can be fixed on the panel of the mold box 400. In this way, in the demolding and assembling of the side mold 100, only the single-sided rotating shaft 4 needs to be rotated, which can be completed in the vertical mold equipment, without the need to unload the side mold, thereby improving the production efficiency. Of course, after the prefabricated component is produced, the demolding can be performed after the prefabricated component and the mold which is not removed are hoisted out of the vertical mold equipment as a whole.

[0053] The specific examples are applied to elaborate the inventive concept in detail in this article, and the above embodiment description is only for helping to understand the core idea of the present application. It should be pointed out that, for ordinary skilled in the art, any obvious modification, equivalent replacement or other improvement made without departing from the inventive concept should be included in the protection scope of the present application.
