Description

Technical Field

[0001] This invention relates to the technical field of building materials, specifically to a mold and pressure molding method for manufacturing inorganic adhesive composite bamboo boards. Background Technology

[0002] Bamboo and wood are unique among all building materials in that they can grow naturally, making them environmentally friendly and compliant with sustainable development principles. Compared to wood, bamboo can be harvested and used after four years of growth, and its strength is also higher, making its utilization even more important. Furthermore, bamboo buildings, due to their light weight and high strength, possess excellent earthquake resistance.

[0003] Traditional construction primarily uses reinforced concrete and clay bricks. The production of these materials not only consumes large amounts of non-renewable resources such as sand, stone, and clay, but also consumes significant amounts of energy and emits carbon dioxide, contradicting the goals of green and environmentally friendly practices. Therefore, the rational utilization of bamboo resources to replace traditional building materials has become an urgent priority.

[0004] Patents with application numbers 202010239326.5 and 202010239335.4 disclose the use of an inorganic adhesive produced from components such as magnesium oxide, magnesium sulfate heptahydrate, silica fume, silica sol, lithium silicate, sodium silicate, citric acid, microcrystalline cellulose, nanocellulose whiskers, aminotrimethylenephosphonic acid, and water to prepare bamboo and wood building materials. Patents with application numbers 202210575079.5, 202310073807.7, and 202310076789.8 disclose methods for preparing bamboo and wood components using the aforementioned inorganic adhesive and bamboo. Components produced by this method exhibit high strength, fire resistance, and corrosion resistance. The preparation of bamboo composite components using this inorganic adhesive requires first thinning the bamboo, then spraying the inorganic adhesive, placing it in layers within a steel template under bidirectional pressure up to 3 MPa, and finally curing and demolding. Existing processing molds are mostly 3m long steel templates with a cross-section of 0.4m × 0.4m. The formed composite components need to be sawn to produce the required beams, columns, etc. However, due to the limited mold width (only 0.4m) and the limitations of the compression equipment, assembling wall panel components requires multiple 0.4m wide panels, making joint treatment difficult and limiting assembly to one-way panels along the column reinforcement direction. If wider panels are to be produced, greater downward pressure compression equipment is needed, significantly increasing equipment requirements. Patent application number 202210909124.6 proposes a structure for inorganic adhesive two-way wall panels, but fails to propose a mold with pressure forming function, and does not propose a method for extending wall panel components whose length and width exceed the length of bamboo. Furthermore, the bamboo inserted into the mold before pressure is loose; existing molds often estimate the amount of bamboo added visually, and bamboo exceeding the top surface of the mold easily scatters outside the mold during pressure. Therefore, it is essential to develop a pressure formwork device and process that is suitable for various board and wall sizes and models and can overcome the above-mentioned process defects. Summary of the Invention

[0005] To address the technical problems existing in the preparation of wide bamboo panels, such as difficulties in splicing, the limitation to producing only unidirectional panels, and existing process defects, this invention provides a mold and pressure molding method for producing inorganic adhesive composite bamboo panels, thus solving the aforementioned problems. This invention employs a panel mold, combined with different bamboo reinforcement arrangements, to produce inorganic adhesive composite bamboo panels that can be unidirectionally pressure-molded in one step, taking advantage of the large length and width but small thickness of the wall panels. This eliminates the need for sawing and the seams caused by splicing multiple panels.

[0006] In a first aspect, the present invention provides a mold for manufacturing inorganic adhesive composite bamboo boards, comprising a pressure platform, a board mold, and a top cover; the pressure platform includes a steel frame and a hydraulic device mounted on the steel frame, the steel frame including four columns, two parallel upper crossbeams welded to the top of the columns, and two parallel lower crossbeams welded to the bottom of the columns; two secondary beams are welded to the middle of the two upper crossbeams; the hydraulic device is mounted on the two secondary beams; a platform base plate is provided at the bottom of the pressure platform; several bolt holes are opened on the platform base plate in a horizontal and vertical arrangement; bolts are installed in the bolt holes, and the bolts are used to fix the side guards; the distance between the bolt holes is different, which is prepared for processing boards of different lengths and widths. The side guards fixed by bolts are the support for the side plates in the board mold, and have a certain strength and rigidity.

[0007] The sheet metal mold includes a mold base plate and four side plates. The mold base plate is fixed within the space enclosed by the four side plates, and the side plates are placed on the mold base plate and abut against the side plates. Every two side plates are connected by a pivot. A groove parallel to the length of the side plate is opened on the top of the side plate. A movable baffle is installed in the groove. A spring is installed at the bottom of the groove, and the spring abuts against the movable baffle. After the movable baffle moves into the groove, its top is flush with the top of the side plate. The outward extension height of the movable baffle is 1 / 10 to 1 / 8 of the height of the side plate. The top cover is placed on the movable baffle, and its edge covers the movable baffle.

[0008] Furthermore, the outer edge of the groove in the side plate is provided with a cutting edge, which serves as a guide device during the pressing down of the top cover.

[0009] Furthermore, the side panels are equipped with multiple clips on their outer sides, and the top cover has hooks on its edge that mate with the clips. When the top cover is pressed down, the hooks can be fixed to the clips to maintain the pressure level inside the template. After the panels inside the curing template are fixed and formed, the hooks can be removed to unload and demold.

[0010] Furthermore, the upper surface of the top cover is welded with reinforcing ribs; there are multiple reinforcing ribs, arranged in a crisscross pattern; a load-bearing plate is welded to the center of the top cover where the reinforcing ribs are located.

[0011] Furthermore, a V-groove is provided at the edge of the lower surface of the top cover. The V-groove works in conjunction with the cutting edge. When the top cover is pressed down, the cutting edge provided at the outer edge of the groove of the side plate is inserted into the V-groove to achieve precise positioning of the top cover and the plate mold.

[0012] Secondly, the present invention also provides a pressure molding method for producing inorganic adhesive composite bamboo boards using the above-mentioned mold, comprising the following steps:

[0013] (1) Select the position of the bolt holes on the platform base plate according to the size of the processing plate, and fix the side guard with bolts;

[0014] (2) Install the side panel onto the inside of the side guard;

[0015] (3) Bamboo strips are laid layer by layer in the mold according to the direction of bamboo strip laying. The bamboo strips are pre-impregnated with inorganic glue. If bamboo strip joints are required, joints are set according to regulations. If conduit boxes or junction boxes are required, they are laid according to regulations. Finally, the top row of bamboo strips is filled to be flush with the top of the movable baffle.

[0016] (4) Hoist the top cover above the plate mold, align it, and then apply pressure to the top cover with a jack;

[0017] (5) Remove the side panel and move the mold and top cover to the curing room; cure at 30℃ for 20~24h, remove the top cover, rotate the side panel to take out the formed inorganic adhesive composite bamboo board from the mold, continue curing for 150h to obtain inorganic adhesive composite bamboo board.

[0018] Furthermore, when the inorganic adhesive composite bamboo board is made into a one-way board, the bamboo ribs are evenly distributed in the same direction within the template. Generally speaking, the direction in which the bamboo ribs are distributed is the main stress direction of the one-way board.

[0019] Furthermore, when the inorganic adhesive composite bamboo board is made into a two-way board, the nth layer of bamboo ribs in the template is arranged perpendicularly to the (n+1)th layer of bamboo ribs, thus forming a two-way board; where n is a positive integer. This board can withstand force in two mutually perpendicular directions.

[0020] Furthermore, when the side length of the inorganic adhesive composite bamboo board is longer than the length of the bamboo ribs, the bamboo ribs need to be extended. To ensure reliable force transmission at the joint, the tops of adjacent bamboo ribs must be staggered.

[0021] Furthermore, when fabricating boards with overlapping bamboo reinforcement, the following method is used:

[0022] If the bamboo reinforcement joint in the first column of the 3n-2 (n is a positive integer) layer is 1 / 4 span from the end of the board, then the bamboo reinforcement joint in the second column will be 1 / 2 span from the end of the board, and the bamboo reinforcement joint in the third column will be 3 / 4 span from the end of the board. The joint sequence of the first three columns is repeated starting from the fourth column.

[0023] In the 3n-1 (n is a positive integer) layer, the bamboo reinforcement joint in the first column is located 1 / 2 span from the end of the board, the bamboo reinforcement joint in the second column is located 3 / 4 span from the end of the board, the bamboo reinforcement joint in the third column is located 1 / 4 span from the end of the board, and the joint sequence of the first 3 columns is repeated starting from the fourth column.

[0024] In the 3nth (n is a positive integer) layer, the bamboo reinforcement joint in the first column is located 3 / 4 of the span from the end of the board, the bamboo reinforcement joint in the second column is located 1 / 4 of the span from the end of the board, and the bamboo reinforcement joint in the third column is located 1 / 2 of the span from the end of the board. Starting from the fourth column, the joint sequence of the first three columns is repeated.

[0025] When fabricating a unidirectional plate, the odd-numbered layers are arranged in the same direction as the even-numbered layers; when fabricating a two-way plate, the odd-numbered layers are arranged perpendicularly to the even-numbered layers.

[0026] This arrangement ensures that the joints are spaced at least 1 / 4 span apart between adjacent bamboo reinforcement joints within each layer, and also at least 1 / 4 span apart between bamboo reinforcement joints in adjacent layers. This guarantees the proper transfer of force across the bamboo reinforcement.

[0027] Furthermore, when the inorganic adhesive composite bamboo board being manufactured requires the installation of conduits, the conduits are installed parallel to the direction of the bamboo fibers, and the conduits are covered with a bamboo fiber layer of at least one thickness from the outer surface of the board. In addition, the conduits can withstand a pressure of 3MPa.

[0028] The beneficial effects of this invention are as follows:

[0029] (1) Based on the characteristics of the wall panel having a large length and width but a small thickness, the present invention provides a mold with unidirectional pressure and side baffles to withstand lateral pressure, which is simpler in structure than the traditional inorganic glue mold with bidirectional loading. After loading, it is formed in one step, without the need for sawing or processing, and there are no seams caused by splicing multiple panels.

[0030] (2) By setting up a movable baffle, the present invention not only prevents the bamboo fiber material that is higher than the mold from falling outward, but also by setting the ratio of the height of the baffle to the height of the mold, it is only necessary to compress the top cover to be flush with the top surface of the template to obtain an inorganic adhesive composite bamboo board with an appropriate compression ratio (90%), without having to control the pressure value to reach 3MPa, which is simpler than the traditional pressure control method.

[0031] (3) The present invention can also use hooks and clamps to maintain the pressure inside the mold, and use the pivot between the side blocks to facilitate the assembly and disassembly of the template, making the construction process convenient.

[0032] (4) The present invention provides multiple rows of bolt holes on the platform base plate, which can fix various types of molds, increasing the versatility of the platform.

[0033] (5) In the production of the bamboo reinforcement overlapping panel, the present invention achieves bamboo reinforcement extension by reasonably setting the joint position, and can make full use of the cut bamboo reinforcement scraps. The conduit is set in the panel along the parallel direction of the bamboo reinforcement, which reduces the impact of the conduit on the integrity of the bamboo reinforcement and maintains the beautiful bamboo grain appearance of the bamboo composite panel.
