Description

Technical Field

[0001] This invention belongs to the technical field of integral cast-in-place cement house molds, specifically, it relates to an inner template structure for an active graded detachment mold of a cement house. Background Technology

[0002] Currently, in the construction of concrete structures, to improve the overall strength of the structure and the efficiency of the pouring and subsequent steam curing processes, monolithic pouring and steam curing are mostly adopted. In actual pouring operations, because the outer formwork is located on the periphery of the concrete structure, the closing and demolding operations of the outer formwork are relatively convenient, and alignment is easily controlled with high accuracy. However, the inner formwork is enclosed within the outer formwork, and especially after concrete pouring, it cannot be observed visually. Therefore, the alignment between inner formwork members and whether they are in place cannot be guaranteed during both closing and demolding processes; furthermore, the efficiency of closing and demolding the inner formwork is lower. Summary of the Invention

[0003] This invention provides an internal formwork structure for active graded demolding of cement plants, which enables rapid demolding of the internal formwork and ensures that the internal formwork is aligned with each other during demolding and in place during demolding, thereby improving the efficiency of internal formwork demolding and reducing labor intensity and workload.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An inner formwork structure for active graded detachment of cement formwork is disclosed. The inner formwork structure is disposed between the outer formwork and the inner fixing frame, forming a casting cavity between the inner formwork structure and the outer formwork. The inner formwork structure includes a formwork body whose lower end is pivotally connected to a base. An angle formwork is disposed between two adjacent formwork bodies. The lower end of the angle formwork is pivotally connected to the base at a corresponding position. Each formwork body is driven to open and close by a corresponding first driving member, and each angle formwork is driven to open and close by a corresponding second driving member.

[0006] Furthermore, the first driving component includes a first hydraulic cylinder, one end of which is hinged to the inner fixed frame, and the other end of which is hinged to the upper part of the template body. The upper end of the template body moves in an opening and closing motion toward or away from the outer template under the drive of the first hydraulic cylinder.

[0007] Furthermore, a plurality of first pivot ears are fixed at intervals along the length of the template body on the base, and a first pivot member is fixed at the lower end of the template body at a position corresponding to each first pivot ear. The first pivot member is connected to the corresponding first pivot ear through a pivot shaft.

[0008] Furthermore, a first crossbeam is fixed at the upper part of the template body, one end of the first driving member is hinged to the first crossbeam, and a second crossbeam is fixed at the lower part of the template body, with the upper end of the first pivot member fixed to the second crossbeam.

[0009] Furthermore, the two ends of the first crossbeam extend out from the two sides of the template body, and the two ends of the second crossbeam extend out from the two sides of the template body. When the template body and the corner template are closed, the two ends of the first crossbeam and the two ends of the second crossbeam press against the surface of the corresponding corner template.

[0010] Furthermore, the second driving component includes a second hydraulic cylinder, one end of which is hinged to the inner fixed frame, and the other end of which is hinged to the upper position of the corner template. The upper end of the corner template moves in an opening and closing motion toward or away from the diagonal direction of the corresponding two outer templates under the drive of the second hydraulic cylinder.

[0011] Furthermore, a second pivot lug is fixed on the base and at the corner template, and a second pivot member is fixed at the lower end of the corner template at a position corresponding to the second pivot lug. The second pivot member is connected to the corresponding second pivot lug via a pivot shaft.

[0012] Furthermore, a first bent edge is constructed at the upper end of the template body, and the first bent edge bends inward and upward. A second bent edge is constructed at the upper end of the corner template. When the template body and the corner template are closed, the surface of the casting cavity formed by the second bent edge and the surface of the casting cavity formed by the adjacent first bent edge are located on the same plane.

[0013] Furthermore, a top template is provided at the upper end of the space enclosed by the inner template structure and the outer template. The edge of the top template has a third bent edge. When the template body and the corner template are closed, the outer surfaces of the first bent edge, the second bent edge and the third bent edge are all located on the same plane.

[0014] The present invention, by employing the aforementioned structure, achieves the following technical advancements compared to existing technologies: The inner template structure of the present invention includes a template body and corner templates. The corner templates are located between two adjacent template bodies. The function of the corner templates is twofold: firstly, to facilitate alignment of the template bodies during mold closing, preventing misalignment or overalignment; and secondly, to enable rapid demolding of the template bodies and corner templates. Specifically, the mold closing and demolding of the template bodies or corner templates are achieved by operating the first or second driving component. Moreover, during the mold closing process, the second driving component is first controlled to drive the corner templates to close, i.e., the corner... The template gradually closes to a predetermined position using its lower pivot point as the axis. Then, the first driving component is controlled to drive the template body to close, that is, the template body gradually closes to the predetermined position using its lower pivot point as the axis, and the corresponding end faces of the template body and the corner templates are aligned. During demolding, the template body is demolded first, and then the corner templates are demolded, thus demolding in an orderly and rapid manner. In summary, the present invention achieves rapid mold closing or demolding of the inner templates, and ensures that the inner templates are aligned with each other during mold closing and are in place during demolding, thereby improving the efficiency of mold closing and demolding of the inner templates and reducing labor intensity and workload.

Detailed Implementation

[0025] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0026] This invention discloses an inner formwork structure for an active graded and detachable formwork system in cement plants, such as... Figures 1-4 As shown, the inner template structure is disposed between the outer template 1 and the inner fixing frame 8, and the casting cavity is formed between the inner template structure and the outer template 1. The inner template structure includes a template body 2, the lower end of which is pivotally connected to the base 4. An angle template 3 is disposed between two adjacent template bodies 2, the lower end of which is pivotally connected to the base 4 at a corresponding position. In this invention, each template body 2 is driven to open and close by a corresponding first driving member 11, and each angle template 3 is driven to open and close by a corresponding second driving member 12. Furthermore, in this invention, all angle templates 3 and all template bodies 2 complete their actions simultaneously during mold closing and demolding, and the actions of the angle templates 3 and template bodies 2 are executed separately, facilitating mold closing and demolding. The working principle and advantages of this invention are as follows: The inner template structure of this invention includes a template body 2 and a corner template 3. The corner template 3 is located between two adjacent template bodies 2. The function of the corner template 3 is, on the one hand, to facilitate the alignment of the template body 2 during mold closing, avoiding situations where the template body 2 is not properly aligned or over-aligned during mold closing; on the other hand, to enable rapid demolding of the template body 2 and the corner template 3. Specifically, the mold closing and demolding of the template body 2 or the corner template 3 are achieved by operating the first driving component 11 or the second driving component 12. Moreover, during the mold closing process, the second driving component 12 is first controlled to drive the corner template 3 to close, that is, the corner template 3 closes with its... The lower pivot joint is used as an axis to gradually close to a predetermined position. Then, the first driving component 11 is controlled to drive the template body 2 to close the mold. That is, the template body 2 gradually closes to the predetermined position with its lower pivot joint as the axis, and the corresponding end faces of the template body 2 and the corner template 3 are aligned. During demolding, the template body 2 is demolded first, and then the corner template 3 is demolded, thus demolding in an orderly and rapid manner. In summary, the present invention realizes the rapid closing or demolding of the inner template and ensures that the inner templates are aligned with each other during mold closing and are in place during demolding, thereby improving the efficiency of inner template closing and demolding, and reducing labor intensity and workload.

[0027] As a preferred embodiment of the present invention, such as Figure 3 As shown, the first driving component 11 includes a first hydraulic cylinder, one end of which is hinged to the inner fixed frame 8, and the other end of which is hinged to the upper part of the template body 2. The upper end of the template body 2, driven by the first hydraulic cylinder, moves in an opening and closing motion toward or away from the outer template 1, thereby achieving the closing or demolding of the template body 2. In this embodiment, the second driving component 12 includes a second hydraulic cylinder, one end of which is hinged to the inner fixed frame 8, and the other end of which is hinged to the upper part of the corner template 3. The upper end of the corner template 3, driven by the second hydraulic cylinder, moves in an opening and closing motion toward or away from the diagonal direction of the two corresponding outer templates 1, thereby achieving the closing or demolding of adjacent template bodies 2.

[0028] In a preferred embodiment of the present invention, the preferred manner in which the template body 2 is pivotally connected to the base 4 and the corner template 3 is pivotally connected to the base 4 is as follows: Figure 4 As shown, multiple first pivot ears 6 are fixed at intervals along the length of the template body 2 on the base 4. Multiple first pivot members 15 are fixedly arranged at the lower end of the template body 2. These first pivot members 15 are arranged one-to-one with the aforementioned multiple first pivot ears 6, and each first pivot member 15 is connected to the corresponding first pivot ear 6 through a pivot shaft. In this embodiment, a second pivot ear 7 is fixed on the base 4 and located at the corner template 3. A second pivot member 16 is fixedly arranged at the lower end of the corner template 3, and the second pivot member 16 is arranged corresponding to the second pivot ear 7. The second pivot member 16 is connected to the corresponding second pivot ear 7 through a pivot shaft. Since the lower ends of the template body 2 and the corner template 3 are pivotally connected to the base 4 in this embodiment, it facilitates the mold closing and demolding operations. Moreover, after the mold is closed and during pouring and steam curing, the lower part of the template body 2 and the corner template 3 bears a large amount of concrete pressure and external expansion force, while the upper part bears a smaller amount of concrete pressure and external expansion force. In this way, the lower pivot locks the lower position, and the upper part is locked by the first driving member 11 and the second driving member 12. Thus, the supporting force borne by the first driving member 11 and the second driving member 12 is small, and it will not cause damage to the first driving member 11 and the second driving member 12 or fail to maintain the predetermined position of the template body 2 and the corner template 3. Furthermore, the first driving member 11 and the second driving member 12 only need to provide a very small external force to complete the demolding or mold closing action. At the same time, the side wall of the poured cement chamber will not be damaged during the demolding process.

[0029] As a preferred embodiment of the present invention, in order to strengthen the template body 2 and the corner template 3, and to provide a connection position for the first driving member 11 and the first pivot member 15, such as... Figures 3-4As shown, a first crossbeam 13 is fixed at the upper part of the template body 2, one end of the first driving member 11 is hinged to the first crossbeam 13, and a second crossbeam 14 is fixed at the lower part of the template body 2. The upper end of the first pivot member 15 is fixed to the second crossbeam 14. In this embodiment, in order to limit the two adjacent template bodies 2 when the mold is closed and to ensure that the corresponding end faces of the corner template 3 and the template body 2 are aligned, the two ends of the first crossbeam 13 extend out of the two side edges of the template body 2, and the two ends of the second crossbeam 14 extend out of the two side edges of the template body 2, respectively. Moreover, when the template body 2 and the corner template 3 are closed, the two ends of the first crossbeam 13 and the two ends of the second crossbeam 14 press against the surface of the corresponding corner template 3, respectively. Furthermore, during demolding, due to the restriction of the corner template 3 by the first crossbeam 13 and the second crossbeam 14, the demolding operation of the template body 2 needs to be performed first, and then the demolding operation of the corner template 3 needs to be performed.

[0030] As a preferred embodiment of the present invention, in order to facilitate demolding and ensure the strength of the upper inner edge of the poured cement structure, such as... Figure 3 As shown, a first bent edge 9 is constructed at the upper end of the template body 2, which bends inward and upward at an angle, and a second bent edge 10 is constructed at the upper end of the corner template 3. Figures 6-7 As shown, when the template body 2 and the corner template 3 are closed, the surface of the casting cavity formed by the second bent edge 10 and the surface of the casting cavity formed by the adjacent first bent edge 9 are located on the same plane. Figure 5 As shown, in this embodiment, a top template 5 is provided at the upper end of the space enclosed by the inner template structure and the outer template 1, and the edge of the top template 5 has a third bent edge 17. Figure 7 As shown, when the formwork body 2 and the corner formwork 3 are closed, the outer surfaces of the first bent edge 9, the second bent edge 10, and the third bent edge 17 are all located on the same plane. Due to the constraints of the first bent edge 9, the second bent edge 10, and the third bent edge 17, the inner edge of the upper end of the cement house forms a chamfer, which improves the connection strength between the top and the side of the cement house. Moreover, during the subsequent demolding process, the upper ends of the formwork body 2 and the corner formwork 3 can be smoothly separated from the cement house wall.
