[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] 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. It should also be emphasized that bamboo buildings, due to their light weight and high strength, have excellent earthquake resistance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a method for manufacturing an inorganic adhesive composite bamboo and wood structure prefabricated house. This method utilizes inorganic adhesive to bond bamboo and wood reinforcements to prepare wall panels and floor slabs, thereby forming an integrated prefabricated house.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a method for manufacturing an inorganic adhesive composite bamboo-wood structure prefabricated house, comprising the following steps: The wall panels and floor slabs are fabricated and covered with an inorganic adhesive. The four sides of the wall panels and floor slabs are processed into concave and convex shapes to form outward-protruding joints for assembly and splicing. Wall panels are connected to each other in an orthogonal staggered manner using outward-facing joints, and wall panels and floor slabs are connected to each other in an orthogonal staggered manner using outward-facing joints, thus assembling them into a complete prefabricated house.

[0006] As a further technical solution, when wall panels are vertically orthogonally connected to each other, and when wall panels and floor slabs are horizontally orthogonally connected: the protruding joints are set to have a length of one wall thickness and a spacing of one wall thickness.

[0007] As a further technical solution, when two wall panels are parallel and orthogonally connected to another wall panel at a vertical joint, when two floor slabs are parallel and orthogonally connected to another wall panel at a horizontal joint, and when two wall panels are parallel and orthogonally connected to another floor slab at a horizontal joint: the outward protrusion joint of the parallel connecting panels is set as T-shaped, with a total length of twice the wall thickness, a total width of three times the wall thickness, and a clear distance of one wall thickness; the outward protrusion joint of the orthogonal panels is set with a length of one wall thickness and a spacing of one wall thickness.

[0008] As a further technical solution, when two parallel floor slabs and two parallel wall panels are orthogonal in the horizontal direction, the protruding joints of the two parallel floor slabs or wall panels are set in a T shape, with a total length of twice the wall thickness, a total width of three times the wall thickness, and a spacing of one wall thickness; the other two protruding joints are processed to have a length of one wall thickness and a net distance of twice the wall thickness.

[0009] As a further technical solution, when assembling wall panels and floor slabs, an assembly sequence of bottom to top and inside to outside is adopted.

[0010] As a further technical solution, connectors are installed at the joints between wall panels and between wall panels and floor slabs: holes are drilled on both sides of the convex and concave joints between wall panels and between wall panels and floor slabs, steel tie rods with holes are installed, bolts are inserted, and nuts are tightened to complete the connection.

[0011] As a further technical solution, the manufacturing process of wall panels and floor slabs is as follows: Bamboo and wood materials are split and separated into multiple ribs along the fiber direction. The ribs are placed orthogonally or transversely in layers within the template of the wall panel or floor panel. Inorganic glue is poured into the template to fully wrap the bamboo and wood rib materials, and then pressure is applied to the top to form the shape.

[0012] As a further technical solution, when door and window openings or stair openings need to be left in the wall panel or floor slab, an inner frame is set inside the template, and the bamboo and wood reinforcements inside the template are broken at the inner frame.

[0013] As a further technical solution, wall panels are spliced ​​together to form an inorganic bamboo-wood structure wall, and earthwork is excavated below the wall to set up a reinforced concrete strip foundation.

[0014] As a further technical solution, a strip groove is set in the reinforced concrete strip foundation, the inorganic bamboo and wood structure wall is vertically inserted into the strip groove, and the gap between the wall and the groove is filled with concrete.

[0015] The beneficial effects of the present invention are as follows: The manufacturing method of this invention uses bamboo and wood materials and inorganic adhesives to form wall panels and floor slabs. The processed wall panels, floor slabs and other components can be made into standard components that can be assembled on site, reducing wet operations such as concrete pouring and steel structure welding, which is conducive to civilized on-site construction.

[0016] The manufacturing method of this invention involves processing the four sides of the wall panels and floor slabs into concave and convex shapes to form outwardly protruding joints. During assembly, the outwardly protruding joints of adjacent panels are connected in an alternating manner. Furthermore, each outwardly protruding joint is configured in a different form according to the different connection positions. The assembled prefabricated house structure is more stable and reliable, and the installation process is simple and easy to implement.

[0017] The manufacturing method of this invention uses inorganic adhesive bamboo and wood structure to make prefabricated houses, which can make full use of renewable resources such as bamboo and wood and reduce carbon emissions. Attached Figure Description

Detailed Implementation

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] In a typical embodiment of the present invention, such as Figure 1 As shown, a method for manufacturing an inorganic adhesive composite bamboo and wood structure prefabricated house is proposed. This method uses inorganic adhesive to bond bamboo and wood reinforcements to prepare wall panels and floor slabs, forming an integrated prefabricated house.

[0023] The production method includes the following steps: 1. Fabrication of components such as wall panels and floor slabs; First, bamboo and wood materials are split and separated into multiple ribs along the fiber direction. The ribs are then placed in the template of the wall panel or floor panel in a layered manner, orthogonally or transversely along the longitudinal or transverse direction. When using bamboo materials, the bamboo ribs 1 placed longitudinally after separation and the bamboo ribs 2 placed transversely after separation are arranged alternately.

[0024] The thickness of the template is determined based on the load-bearing capacity of the component and parameters such as thermal insulation and sound insulation.

[0025] Inorganic adhesive is poured into the template to fully wrap the bamboo and wood reinforcement materials. Then, pressure is applied to the top to form an inorganic binder 3 on the surface and in the gaps of the bamboo and wood reinforcement materials.

[0026] In this embodiment, the inorganic adhesive is made of magnesium oxide, magnesium sulfate heptahydrate, silica fume, silica sol, lithium silicate, sodium silicate, citric acid, microcrystalline cellulose, nanocellulose whiskers, aminotrimethylenephosphonic acid, water, and other components.

[0027] If wall panels or floor slabs require openings for doors, windows, or stairs, an inner frame must be installed within the formwork. The bamboo or wooden reinforcement within the formwork should be disconnected when it encounters the inner frame. For example, a window opening 4 can be made in the middle of the bamboo or wooden reinforcement, and a door opening 5 can be made at the bottom of the bamboo or wooden reinforcement.

[0028] After the wall panels or floor slabs have reached the required strength and the formwork is removed, the four sides are processed to create joints with concave and convex surfaces, in preparation for the construction of prefabricated houses.

[0029] 2. Basic setup of prefabricated houses; Wall panels are spliced ​​together to form an inorganic adhesive bamboo-wood structure wall. Excavation is carried out beneath the wall to construct a reinforced concrete strip foundation 6. At the location of the wall within the foundation, a strip trench 7, slightly wider than the wall itself, is constructed. The inorganic adhesive bamboo-wood structure wall 8 is vertically inserted into the strip trench 7, and the gap between the wall and the trench is filled with concrete.

[0030] 3. Connection methods between walls and floors; To achieve a reliable connection between wall panels and floor slabs, the four sides of the wall panels and floor slabs are processed into concave and convex shapes to form outward-protruding joints. Through the connection of outward-protruding joints between wall panels and between wall panels and floor slabs, assembly and splicing are achieved to form an integrated prefabricated house.

[0031] Each wall panel includes an inner transverse wall 9 of inorganic adhesive bamboo wood structure, an outer transverse wall 10 of inorganic adhesive bamboo wood structure, an inner longitudinal wall 11 of inorganic adhesive bamboo wood structure, and an outer longitudinal wall 12 of inorganic adhesive bamboo wood structure. The longitudinal and transverse walls are orthogonally and intersectingly connected, and the wall panels and floor slabs are also orthogonally and intersectingly connected, forming connection nodes at the connection points.

[0032] Specifically, connection nodes are divided into connection nodes between wall panels and connection nodes between wall panels and floor slabs. Connection nodes between wall panels are further divided into: connection node 13 between outer longitudinal walls and outer transverse walls, connection node 14 between outer longitudinal walls and inner transverse walls, and connection node 15 between inner longitudinal walls and inner transverse walls. Connection nodes between wall panels and floor slabs are further divided into: connection node 16 between inner walls and floor slabs on intermediate floors, connection node 18 between outer walls and floor slabs on intermediate floors, connection node 17 between inner walls and floor slabs on the top floor, and connection node 19 between outer walls and floor slabs on the top floor, etc.

[0033] To achieve interlocking and staggered joints between wall panels and floor slabs, the external protruding joints of several nodes are processed into the following styles: (1) Vertical orthogonal connection between wall panels and horizontal orthogonal connection between wall panels and floor slabs: The external protruding joints are processed to have a length equal to one wall thickness and a spacing equal to one wall thickness; (2) Two wall panels are parallel and orthogonally connected to another wall panel at a vertical joint, two floor slabs are parallel and orthogonally connected to another wall panel at a horizontal joint, and two wall panels are parallel and orthogonally connected to another floor slab at a horizontal joint: The external protruding joints of the parallel connected panels are processed into external... The shape is T-shaped, the total length is twice the wall thickness, the total width is three times the wall thickness, and the net distance is one wall thickness; the orthogonal slab protrusion joints are processed to a length of one wall thickness and a spacing of one wall thickness; (3) When two parallel floor slabs and two parallel wall panels are orthogonal in the horizontal direction, the protrusion joints of the two parallel floor slabs or wall panels are processed to a T-shape, the total length is twice the wall thickness, the total width is three times the wall thickness, and the spacing is one wall thickness; while the other two protrusion joints are processed to a length of one wall thickness and a net distance of twice the wall thickness.

[0034] In order to achieve smooth assembly, the wall panels and floor slabs are assembled in a bottom-to-top and inside-to-outside order.

[0035] Connectors are installed at the joints between wall panels and between wall panels and floor slabs. Specifically, to form a whole assembled prefabricated house, holes are drilled on both sides of the convex and concave joints between wall panels and between wall panels and floor slabs, i.e., wall panel connection holes 28. Perforated steel tie rods, i.e., wall panel connection rods 29, are installed. The position of the holes on the steel tie rods corresponds to the holes on the wall panels or floor slabs. The hole diameter should be slightly larger than the bolt diameter. After inserting the bolts, tighten the nuts to complete the connection.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
