Description

Technical Field

[0001] This utility model belongs to the field of prefabricated green building technology, specifically relating to a rapid prefabricated block system based on renewable wood and bamboo materials, which is suitable for the modular construction of low-rise building structures. Background Technology

[0002] Modern bamboo and wood structures, with their significant carbon sequestration advantages and sustainable characteristics, are becoming an important development direction in the field of green building. Against the backdrop of the construction industry's low-carbon transformation, the industry has placed higher demands on the integrity, ease of construction, and flexibility of bamboo and wood structures. However, traditional bamboo and wood structures have inherent limitations, such as reliance on on-site manual processing and high requirements for craftsmanship, which restrict their modernization and promotion. Therefore, modular assembly technology provides an innovative solution for bamboo and wood structure construction. However, existing modular assembly technology still has many problems: on the one hand, limited internal space design cannot effectively accommodate pipelines, insulation, or sound insulation materials; low structural flexibility, or reliance on complex fixing methods, leads to low construction efficiency and limited functional expandability, making it difficult to meet the modern building's demands for lightweight, multi-functional integration, and rapid assembly; on the other hand, large-size modules (such as CLT wall panels) are subject to road width restrictions, increasing transportation costs; overall module modification requires destructive demolition, resulting in high maintenance costs; installing excessively large components can lead to on-site construction difficulties and increased construction errors, etc. Utility Model Content

[0003] The purpose of this utility model is to meet the technical requirements of prefabricated construction of bamboo and wood structures. Considering the convenience of modern bamboo and wood structure construction and the reliability of performance, a high-performance modular wood and bamboo block system and its combination system are proposed for assembling building structures (such as building walls and buildings composed of such walls).

[0004] This utility model provides the following technical solution: a quick-assembly building wood and bamboo block combination system, including terminal blocks, foundation blocks, intersection blocks, steel bars, ingot pins, bottom beams and top beams;

[0005] The terminal block, foundation block, and cross block are three structural forms of wood and bamboo masonry blocks. The terminal block, foundation block, and cross block are installed between the bottom beam and top beam of the wall through steel bars and ingot pins.

[0006] The terminal block is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. One of the plates extends and protrudes on one side, with the protrusion length equal to the net distance of the inner cavity. The cross-section is in the shape of a "6". The flat plates are vertically fixed with pins and a bidirectional through steel bar channel is reserved. The terminal block is used for overlapping at the edge of the wall.

[0007] The base block is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. Two of the plates extend and protrude on one side, with the protrusion length equal to the net distance of the inner cavity. The cross-section is stepped. The flat plates are vertically fixed with pins and a bidirectional through-bar rebar channel is reserved. The base block is used for the middle overlap of the wall.

[0008] The cross block is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. Four of the plates extend and protrude on one side, with the protrusion length equal to the net distance of the inner cavity. The cross section is cross-shaped. The flat plates are vertically fixed by pins, and bidirectional through steel reinforcement channels are reserved. The cross block is used for overlapping at the wall connection.

[0009] The dimensions of the three types of block templates, the reserved channels for rebar holes, and the specifications of the pre-embedded nuts can be changed according to the building's functional requirements.

[0010] Preferably, for a T-shaped wall, the terminal block is located at the edge of the wall, the base block is located in the middle of the wall, and the intersection block is located at the connection point of the wall nodes.

[0011] Preferably, for an L-shaped wall, the terminal block is located at the edge of the wall, the base block is located in the middle of the wall, and the intersection block is located at the joint of the wall nodes.

[0012] Preferably, for a cross-shaped wall, the terminal block is located at the edge of the wall, the base block is located in the middle of the wall, and the intersection block is located at the joint of the wall nodes.

[0013] Preferably, for a straight wall, the terminal block is located at the edge of the wall, and the base block is located in the middle of the wall.

[0014] Preferably, the flat panel is made of wood (such as laminated wood), and more preferably laminated bamboo. Other optional materials include 3D printing materials and plastics. All types of wood (such as solid wood, particleboard, laminated board, plywood, etc.) are within the scope of this utility model.

[0015] Preferably, the pin can be a solid cylindrical pin with a length and diameter matching the pin seat, and fixed by gluing or other fitting methods. Alternative options include screws, expansion bolts, or mortise and tenon joints.

[0016] Preferably, the bottom beam and top beam are connected to the reinforcing steel members using pre-embedded nuts, and the reinforcing steel members are made of high-strength steel, so that the wall has good tensile strength.

[0017] Preferably, the ingot pin is made of bamboo, with a thickness of 1 / 3 of the flat plate thickness, which makes the wall construction and positioning faster and increases the wall's earthquake resistance.

[0018] The beneficial effects of this utility model are as follows: By reserving rebar hole channels, the structural integrity is ensured; the three-dimensional positioning design facilitates the positioning of components by construction personnel, reducing construction difficulty and shortening construction time. This utility model uses dowel pins to assemble the wall, facilitating component positioning; controlled friction sliding and localized plastic compression deformation of the wood effectively offset the energy of earthquakes or wind loads, protecting the main structure. The internal space formed during assembly and the vertical open channels created by protruding parts can be used for laying cables, pipes, temperature control equipment, or for filling with insulating, fireproof, and soundproof materials to enhance the structural compressive strength, while also facilitating later equipment installation. The use of three simple blocks allows for the overlapping of different types of walls, avoiding road transport restrictions and reducing transportation costs. It also avoids installation errors of large components, improving the accuracy of overlapping. It can be quickly disassembled and reassembled according to changes in building usage requirements. The modular installation of large components allows for individual module replacement in case of local damage, without dismantling the entire structure; new materials can be added or filled through open channels to improve wall performance at any time, reducing maintenance costs. Depending on the wall requirements of different regions, any size requirement can be met by changing the diameter of the reinforcing bars and the formwork. The device is easy to install and is not limited by time or space, and can be used on construction sites and in harsh environments. Attached Figure Description

[0032] Example 1:

[0033] like Figure 1-6 As shown, a quick-assembly building wood and bamboo block assembly system includes terminal block 1, foundation block 2, cross block 3, steel reinforcement member 4, bottom beam 5, top beam 6, and ingot pin 7.

[0034] The terminal block 1, the foundation block 2, and the cross block 3 are three structural forms of wood and bamboo block combination. The terminal block 1, the foundation block 2, and the cross block 3 are installed between the bottom beam 5 and the top beam 6 of the wall through steel bars 4 and ingot pins 7.

[0035] The terminal block 1 is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. One of the plates extends and protrudes on one side, with the protrusion length equal to the net distance of the inner cavity. The cross section is in the shape of a "6". The flat plates are vertically fixed by pins, and a bidirectional through steel bar channel is reserved.

[0036] The foundation block 2 is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. Two of them extend and protrude on one side, with the protrusion length equal to the net distance of the inner cavity. The cross-section is stepped. The flat plates are vertically fixed by pins, and a bidirectional through-bar rebar channel is reserved.

[0037] The cross block 3 is formed by four flat plates of equal height and thickness, which are perpendicularly or orthogonally fixed to form a parallelepiped with an open top and bottom. The four plates extend and protrude on one side, with the protrusion length equal to the net distance of the inner cavity. The cross section is cross-shaped. The flat plates are vertically fixed by pins, and a bidirectional through-bar rebar channel is reserved.

[0038] The wall is a T-shaped wall, the terminal block 1 is located at the edge of the wall, the base block 2 is located in the middle of the wall, and the intersection block 3 is located at the connection point of the wall node.

[0039] The above-mentioned rapid-assembly building wood and bamboo block assembly system includes the following steps:

[0040] First step: Install the bottom beam 5 at the bottom of the wall and level it. The bottom beam 5 is equipped with pre-embedded nuts. The steel bar 4 is vertically fixed to the base.

[0041] Second step: Insert terminal block 1, foundation block 2 and cross block 3 layer by layer along the rod, and use the ingot pin 7 to ensure that the protruding part is precisely connected to the lower edge;

[0042] Third step: After the wall is completed, place the top beam 6 and tighten the nuts to compress the module to enhance the structural strength;

[0043] Fourth step: Lay pipelines or inject filling material through the vertical cavity.

[0044] The principle of block assembly is as follows: Due to the different shapes of different types of walls, this patent decomposes the wall construction into three simple blocks, which are then assembled according to the drawings, much like building blocks. Fixing rods are anchored to the base, and the blocks are stacked along the rods, with the protruding parts aligned with the lower layer. A pressure plate is installed at the top of the wall, and nuts are used to compress the blocks, enhancing overall stability. Vertical channels can be used to fill materials or lay pipelines.
