Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a mold and preparation method for an inorganic adhesive composite bamboo arc-shaped component. Background Technology

[0002] Bamboo and wood are unique among all building materials in that they can grow naturally and are environmentally friendly materials that conform to sustainable development. Inorganic adhesive composite bamboo is a new type of green building material, which uses bamboo as the matrix and binds bamboo fibers and other components together with inorganic adhesives.

[0003] Conventional inorganic adhesive composite bamboo is mostly used to prepare columns, beams and slabs with rectangular cross sections. In order to meet the needs of practical engineering, molds that can process curved components have now emerged. The mold is divided into an upper mold and a lower mold, both of which have curved surfaces. By moving the upper and lower molds relative to each other, the glued bamboo can be squeezed, so that the curvature of the glued bamboo component is consistent with the curvature of the curved surface, thus improving the preparation efficiency of curved glued components.

[0004] However, existing molds used for processing curved components have fixed dimensions of the curved surfaces on the upper and lower molds. A set of molds can only produce one type of glued bamboo component with a fixed curvature. Furthermore, the cross-sectional shape and size of the components produced by the upper and lower molds are also fixed and cannot be adjusted according to actual production needs. This results in poor applicability. When producing components with different curvatures and cross-sectional sizes, multiple molds are required, leading to high usage costs. Summary of the Invention

[0005] To address the technical problems of existing molds used for processing curved components, which have fixed dimensions of the curved surfaces on the upper and lower molds and can only produce one type of glued bamboo component with a fixed curvature, resulting in poor applicability and high cost, this invention provides a mold and method for preparing inorganic glued composite bamboo curved components.

[0006] The technical solution of this invention is as follows: This invention provides a mold for preparing inorganic adhesive composite bamboo arc-shaped components, including a base and a cover plate rotatably mounted on the base. The base has a cavity with an upper opening. A first arc-shaped steel template and a second arc-shaped steel template are installed opposite each other within the cavity. The side of the first arc-shaped steel template away from the second arc-shaped steel template is fixedly connected to the side wall of the base via several telescopic connectors. The side of the second arc-shaped steel template away from the first arc-shaped steel template is connected to a pusher via several telescopic connectors. The pusher is slidably disposed within the cavity and is fixedly connected to the side wall of the base via a telescopic drive unit. By connecting the arc-shaped steel template to the base or pusher via telescopic connectors, the curvature of the arc-shaped steel template can be changed by adjusting the length of the telescopic connectors, thus adapting to the needs of preparing components with different curvatures. The pusher not only allows for adjusting the distance between the second and first arc-shaped steel templates as needed to prepare components with different curvatures and cross-sectional dimensions, but also provides stable pressure in conjunction with the telescopic drive unit, providing sufficient pressure support for the molding of the inorganic adhesive composite bamboo components.

[0007] Preferably, several telescopic connectors are evenly spaced along the bending direction of the corresponding arc-shaped steel template. This allows for more balanced stress and curvature adjustment at various points on the arc-shaped steel template, avoiding excessive local deformation that could lead to curvature deviations in the components, thus ensuring the forming accuracy of the arc-shaped components. Compared to fixed arc-shaped molds, this design is better able to adapt to stress requirements under different curvatures.

[0008] Preferably, the cavity is rectangular, with first curved grooves on both sides along its length. These first curved grooves communicate with the cavity, and both ends of the first arc-shaped steel template are inserted into the corresponding first curved grooves, providing space to accommodate changes in the length of the first arc-shaped steel template. The first curved grooves provide flexibility for the length changes of the first arc-shaped steel template as the curvature adjusts, preventing the template from being limited by length variations and thus avoiding the inability to achieve the designed curvature. This solves the limitations of existing molds that cannot adapt to curvature changes, further enhancing the mold's adjustment flexibility.

[0009] Preferably, the push base includes a crossbeam and vertical beams fixedly installed at both ends of the crossbeam. Each vertical beam has a second curved groove, and both ends of the second arc-shaped steel template are inserted into the corresponding second curved groove, providing space to accommodate changes in the length of the second arc-shaped steel template. Providing space to accommodate changes in the length of the second arc-shaped steel template ensures that its curvature can be smoothly adjusted with the telescopic connector. Compared with existing fixed-size molds, multiple curvatures can be precisely adjusted on the same mold, reducing the frequency of mold replacement.

[0010] Preferably, guide grooves are provided on both sides along the length of the cavity, and the two ends of the pusher are slidably disposed within the guide grooves. A baffle is fixedly provided at the end of the vertical beam away from the horizontal beam, and the total length of the baffle and the vertical beam is not less than the length of the guide groove. The guide groove guides the movement of the pusher, ensuring the stability of the second arc-shaped steel template during extrusion. The baffle design prevents the pusher from detaching from the guide groove and avoids bamboo and inorganic adhesive from entering the guide groove during extrusion, thus solving the problems of poor extrusion stability and low component forming quality caused by the fixed structure of existing molds.

[0011] Preferably, the end of the baffle is chamfered to facilitate the insertion of the baffle between the end of the component and the side wall of the cavity.

[0012] Preferably, a limit block is detachably installed inside the guide groove. By replacing the limit blocks of different sizes, the moving distance of the pusher can be adjusted, thereby changing the spacing between the first and second arc-shaped steel templates, enabling the preparation of components with different cross-sectional dimensions. This eliminates the need to prepare multiple molds for different cross-sectional dimensions, reducing usage costs.

[0013] Preferably, the telescopic connector includes a bidirectional screw, with a sleeve threaded to each end of the bidirectional screw. The combination of the bidirectional screw and the sleeve facilitates precise adjustment of the telescopic connector's length, is simple to operate, and offers high adjustment accuracy. It can more accurately control the curvature of the curved steel template, ensuring that the curvature of the component is consistent with the design requirements, and improving the fabrication accuracy of the curved component.

[0014] A preparation method, comprising: First, open the cover and adjust the length of each telescopic connector; After all the telescopic connectors have been adjusted to the correct length, select the limiting block and place it in the guide groove so that the limiting block is close to the first arc-shaped steel template. Bamboo coated with inorganic adhesive is filled between the first and second arc-shaped steel templates; Close and lock the cover plate, start the telescopic drive unit, so that the second arc-shaped steel template moves toward the direction closer to the first arc-shaped steel template until the vertical beam of the push seat contacts the limit block, stop the telescopic drive unit and maintain pressure; After curing, open the cover, reset the pusher, and remove the molded inorganic adhesive composite bamboo arc-shaped component from the cavity.

[0015] By adjusting the length of the telescopic connector and the limiting block, the curvature and cross-sectional dimensions of the component can be flexibly controlled. The operation process is simple and controllable. Compared with the existing preparation method that requires changing different molds, it greatly improves the preparation efficiency of arc components of different specifications and reduces the complexity of operation.

[0016] Preferably, the formula for calculating the length adjustment of the telescopic connector is:

[0017] in, Let be the displacement of the i-th telescopic connector; k is the design curvature of the arc-shaped component; Let be the arc length from the i-th telescopic connector to the center of symmetry of the arc. By calculating the adjustment length of the telescopic connector, the curvature of the arc-shaped steel template can be determined to be highly consistent with the design requirements, reducing errors and solving the problem of component curvature deviation caused by the lack of precise adjustment basis in existing molds. This further improves the manufacturing accuracy and pass rate of arc-shaped components.

[0018] As can be seen from the above technical solutions, the advantages of the present invention are: 1. The curved steel template is connected to the base or pusher by telescopic connectors. The curvature of the curved steel template can be changed by adjusting the length of the telescopic connectors, thereby adapting to the needs of component preparation with different curvatures. The pusher not only allows the distance between the second and first curved steel templates to be adjusted as needed to prepare components with different curvatures and cross-sectional dimensions, but also provides stable pressure in conjunction with the telescopic drive unit, providing sufficient pressure support for the molding of inorganic adhesive composite bamboo components.

[0019] 2. The setting of the first and second curved grooves provides room for the length change of the arc steel template as the curvature is adjusted, ensuring that the curvature can be smoothly changed with the adjustment of the telescopic connector. This avoids the template being restricted by the length change and unable to achieve the designed curvature, solves the limitation of the existing mold that cannot adapt to the curvature change, and further enhances the adjustment flexibility of the mold.

[0022] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Example 1 In a typical embodiment of the present invention, such as Figures 1-3 As shown, a mold for preparing inorganic adhesive composite bamboo arc-shaped components is proposed, comprising: a base 1, a cover plate 2, a telescopic drive unit 4, a pusher 5, a first arc-shaped steel template 6, a second arc-shaped steel template 7, and a telescopic connector 9. A cavity 13 is formed on the base 1. The cover plate 2 is rotatably mounted on the upper surface of the base 1 to cover the cavity 13. The first arc-shaped steel template 6 and the second arc-shaped steel template 7 are installed inside the cavity 13. The first arc-shaped steel template 6 and the second arc-shaped steel template 7 are arranged opposite each other and have the same bending direction. The space between the first arc-shaped steel template 6 and the second arc-shaped steel template 7 is used for extrusion molding of the component. The first arc-shaped steel template 6 is located away from the second arc-shaped steel template 7. One side of the shaped steel template 7 is fixedly connected to the side wall of the chassis 1 through several telescopic connectors 9. The curvature of the first arc-shaped steel template 6 can be adjusted by the telescopic connectors 9. The push seat 5 is located on the side of the second arc-shaped steel template 7 away from the first arc-shaped steel template 6. The push seat 5 is slidably set in the cavity 13. The second arc-shaped steel template 7 is fixedly connected to the push seat 5 through several telescopic connectors 9. The curvature of the second arc-shaped steel template 7 can be adjusted by adjusting the length of the telescopic connectors 9. The side of the push seat 5 away from the second arc-shaped steel template 7 is fixedly connected to the side wall of the chassis 1 through the telescopic drive unit 4. The push seat 5 can also drive the second arc-shaped steel template 7 to move closer to or away from the first arc-shaped steel template 6.

[0024] The mold in this embodiment can adjust the curvature of the first arc-shaped steel template 6 and the second arc-shaped steel template 7 as needed, thereby adapting to the needs of component preparation with different curvatures. The setting of the push seat 5 can not only adjust the distance between the second arc-shaped steel template 7 and the first arc-shaped steel template 6 as needed to realize the preparation of components with different curvatures and different cross-sectional dimensions, but also provide stable pressure in conjunction with the telescopic drive unit 4, providing sufficient pressure support for the molding of inorganic adhesive composite bamboo components.

[0025] It should be noted that cavity 13 is only open at the top, and the bottom of cavity 13 is sealed to prevent leakage of inorganic adhesive.

[0026] Specifically, the chassis 1 includes a cavity 13, a crossbar 14, and a base plate. The crossbar 14 surrounds the periphery of the cavity 13, and the base plate is fixedly installed at the bottom of the cavity 13. The cavity 13 is a rectangular cavity, such as... Figure 2 As shown, the chassis 1 has two first curved grooves 15 and two guide grooves 16. The two first curved grooves 15 are arranged opposite each other on both sides of the cavity 13 along its length. The first curved groove 15 is an arc-shaped groove and is connected to the cavity 13. The bending direction of the first curved groove 15 is the same as the bending direction of the first arc-shaped steel template 6. The two ends of the first arc-shaped steel template 6 are inserted into the corresponding first curved grooves 15, which serves as a limit and provides a space to accommodate the first arc-shaped steel template 6. When the curvature of the first arc-shaped steel template 6 changes, the arc length of the first arc-shaped steel template 6 will change, and the end of the first arc-shaped steel template 6 will move into the first curved groove 15 or be pulled outward from the first curved groove 15.

[0027] The guide groove 16 is a rectangular groove. Two guide grooves 16 are arranged opposite each other on both sides of the length direction of the cavity 13. The guide grooves 16 extend along the length direction of the cavity 13 and are also connected to the cavity 13. The two ends of the push seat 5 are inserted into the corresponding guide grooves 16, and the push seat 5 can move along the length direction of the guide groove 16 to change the position of the push seat 5 and the second arc-shaped steel template 7 on it. The guide groove 16 can limit and guide the push seat 5 to avoid it from deflecting during movement.

[0028] like Figure 3As shown, the pusher 5 includes a baffle 17, a horizontal beam 18, a vertical beam 19, and a second curved groove 20. The length direction of the horizontal beam 18 is perpendicular to the length direction of the cavity 13. Both ends of the horizontal beam 18 are inserted into corresponding guide grooves 16. Vertical beams 19 are fixedly provided at both ends of the horizontal beam 18. The vertical beams 19 and the horizontal beam 18 together form a U-shaped structure. Each vertical beam 19 has a corresponding second curved groove 20. The two second curved grooves 20 are arranged opposite each other, and the bending direction of the second curved grooves 20 is the same as that of the first curved groove 15. Both ends of the second arc-shaped steel template 7 are respectively inserted into the corresponding second curved grooves 20. On the one hand, it serves as a limit, and on the other hand, it is used to accommodate the second arc-shaped steel template 7. When the curvature of the second arc-shaped steel template 7 changes, the arc length of the second arc-shaped steel template 7 will change, and the end of the second arc-shaped steel template 7 will move into the second curved groove 20 or be pulled outward from the second curved groove 20. One side of the crossbeam 18 is fixedly connected to the inner wall of the chassis 1 (i.e., the crossbar 14) through the telescopic drive unit 4 to adjust the overall position of the push seat 5. The other side of the crossbeam 18 is fixedly connected to the second arc-shaped steel template 7 through several telescopic connectors 9 to adjust the curvature of the second arc-shaped steel template 7.

[0029] like Figure 3 As shown, a baffle 17 is fixedly provided at the end of the vertical beam 19 away from the horizontal beam 18. The baffle 17 is a thin plate structure. The total length of the baffle 17 and the vertical beam 19 is not less than the length of the guide groove 16. The baffle 17 is used to block the side of the guide groove 16 to prevent inorganic glue and bamboo from entering the guide groove 16. The end of the baffle 17 is provided with a chamfer 21 so that the baffle 17 can be inserted between the end of the component and the side wall of the cavity 13.

[0030] In this embodiment, there are several telescopic drive units 4. The telescopic drive unit 4 is a hydraulic jack structure used to push the overall movement of the push base 5.

[0031] A limiting block 8 can be detachably installed inside the guide groove 16. The limiting block 8 is a rectangular block with the same width and thickness as the guide groove 16. The length of the limiting block 8 is less than that of the guide groove 16. When the end of the pusher 5 touches the limiting block 8, it will stop sliding and pressing to limit the movement of the pusher 5. In actual use, the distance between the first arc-shaped steel template 6 and the second arc-shaped steel template 7 can be controlled by replacing the limiting blocks 8 of different lengths to achieve the production of components of different widths.

[0032] The cover plate 2 is rotatably connected to the chassis 1 via the pivot 3, and the cover plate 2 and the chassis 1 are also fixed by a lock. The cover plate 2 is used to cover the upper opening of the cavity 13.

[0033] like Figure 1As shown, the telescopic connector 9 includes a sleeve 10 and a bidirectional screw 11. There are two sleeves 10 and one bidirectional screw 11. The bidirectional screw 11 has two external threads with opposite directions. The sleeve 10 has an internal thread for threaded connection with the bidirectional screw 11. The two ends of the bidirectional screw 11 are respectively threaded to a sleeve 10. By rotating the bidirectional screw 11, the two sleeves 10 are driven to move closer or further apart, thereby causing the connected arc-shaped steel template to deform.

[0034] Specifically, the telescopic connector 9 between the first arc-shaped steel template 6 and the chassis 1 has one sleeve 10 that is horizontally fixed to the side wall of the crossbar 14 of the chassis 1 by welding, and the other sleeve 10 that is horizontally fixed to the first arc-shaped steel template 6. The two sleeves 10 are threadedly connected to the bidirectional screw 11. The telescopic connector 9 between the second arc-shaped steel template 7 and the push base 5 has one sleeve 10 that is horizontally fixed to the second arc-shaped steel template 7, and the other sleeve 10 that is horizontally fixed to the push base 5. The two sleeves 10 are connected by the bidirectional screw 11.

[0035] To facilitate the rotation of the bidirectional screw 11, a round hole 12 is provided at the middle position of the bidirectional screw 11 for the insertion of auxiliary tools. The auxiliary tools are then used to drive the bidirectional screw 11 to rotate around the axis, thereby adjusting the length of the telescopic connector 9.

[0036] In this embodiment, several telescopic connectors 9 are fixedly provided between the first arc-shaped steel template 6 and the crossbar 14, and between the second arc-shaped steel template 7 and the push seat 5. The telescopic connectors 9 are evenly spaced along the bending direction of the corresponding arc-shaped steel template to adjust the curvature of the first arc-shaped steel template 6 and the second arc-shaped steel template 7.

[0037] Example 2 In another typical embodiment of the present invention, a preparation method is proposed, which uses the inorganic adhesive composite bamboo arc-shaped component preparation mold mentioned in Example 1 to prepare the inorganic adhesive composite bamboo arc-shaped component. The specific method includes: First, open the cover plate 2. The telescopic drive unit 4 drives the second arc-shaped steel template 7 to move to the starting point. Then, according to the curvature of the components on the design drawings, calculate the displacement of the first arc-shaped steel template 6 and the second arc-shaped steel template 7 at each telescopic connector 9. Rotate the bidirectional screw 11 to adjust the length of each telescopic connector 9.

[0038] The formula for calculating the length adjustment of the telescopic connector 9 is as follows: Assume the design curvature of the curved component is k (curvature) Where R is the radius of the arc-shaped component, the telescopic connectors 9 are evenly spaced along the arc direction, and the arc length of the i-th telescopic connector 9 from the center of symmetry (or reference point) of the arc is . Then the displacement of the arc-shaped steel template at the telescopic connector 9 (i.e., the length that the telescopic connector 9 needs to be adjusted) is calculated. The calculation formula is:

[0039] in, denoted as , where is the displacement of the i-th telescopic connector 9 (i.e., the length by which the telescopic connector 9 needs to be extended or shortened, in mm); and is the design curvature of the arc-shaped component (in mm). Let be the arc length from the i-th telescopic connector 9 to the center of the arc symmetry.

[0040] For example: If the design curvature k of a certain arc-shaped component is 0.02m, that is, R=50m, the arc length of a certain expansion joint 9 from the center of symmetry If the length is 10m, then:

[0041]

[0042] That is, the length that the telescopic connector 9 needs to be adjusted is 0.25m (250mm).

[0043] After all the telescopic connectors 9 have been adjusted to the required length, select the appropriate length of the limiting block 8 according to the width of the arc-shaped component to be processed, and place the limiting block 8 in the corresponding guide groove 16 so that the limiting block 8 is close to the first arc-shaped steel template 6. After the limiting block 8 is placed, bamboo coated with inorganic glue is filled between the first arc-shaped steel template 6 and the second arc-shaped steel template 7. The inorganic glue can be prevented from flowing into the guide groove 16 by the baffle 17. Close the cover plate 2 and use the lock to lock and fix the cover plate 2 to the chassis 1. Then start the telescopic drive unit 4. The telescopic drive unit 4 pushes the push seat 5 to move along the guide groove 16, so that the second arc-shaped steel template 7 moves towards the direction of the first arc-shaped steel template 6 to squeeze the bamboo between the first arc-shaped steel template 6 and the second arc-shaped steel template 7 until the vertical beam 19 of the push seat 5 contacts the limit block 8. Then stop the telescopic drive unit 4 and lock it to maintain pressure. After 24 hours of curing, open the cover plate 2 and use the telescopic drive unit 4 to drive the push seat 5 to reset, and take out the formed inorganic adhesive composite bamboo arc-shaped component from the cavity 13.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
