Definitions

  • the present invention relates to a tenon joint type space lattice structure, and more particularly to a multifunctional space lattice structure having a retaining wall, a water drainage and an earth fill vegetation by jointly using a tenon joint assembling of components and a combining pillar.
  • a tenon joint type space lattice structure includes a predetermined quantity of lattice units and combining pillar and is characterized in that the lattice unit comprises two or more pre-molded components coupled with each other, and a convex tenon and a concave tenon groove disposed on an end of the lattice unit, and the tenon and the tenon groove form a tenon-and-groove structure, such that the tenon protruded between each component is embedded into an adjacent tenon groove and coupled with the tenon groove by a tenon joint assembling process, and the components are coupled with each other in series to constitute a continuously extended lattice unit.
  • the continuous lattice unit further forms a plane year of a space lattice structure, uses the combining pillar to pass through a hollow portion of the component perpendicularly, and connects the plane layers of the lattice unit in series along the direction of the height of the structure, so as to constitute a three-dimensional space lattice structure.
  • the present invention is characterized in that the lattice unit is manufactured in the best mode according to transmitted force, stylish appearance, construction convenience, transportation, vegetation space and economic factors. Therefore, the lattice unit includes a light hollow component made of a light material and a heavy component made of a heavy material.
  • the lattice unit of the heavy component is made of a heavy material such as steel concrete, steel, steel concrete and wood, etc.
  • the heavy component requires a hollow portion at the position of the tenon for passing through a combining pillar, and the lattices of the lattice unit may or may not have a hollow portion depending on the required structural strength, but the overall constructability and cost of the manufacturing process should be taken into consideration. The manufacturing process will become simpler and easier if it is not necessary to build the hollow portion.
  • the lattice unit of the heavy component used for the construction makes the transportation by labor more difficult due to the heavy weight, and thus a hoisting machine is required for the transportation. Furthermore, the flexibility of adjusting the tenon joint assembling process will be affected greatly.
  • the gravitation force produced by the mass of the lattice unit of the heavy component on the structure is one of the structural resistance sources, and thus the constructed tenon joint type space lattice structure is formed as a gravity structure, and heavy filling materials such as soils and stones are filled into the hollow portion of the structure, and the gravitational force produced by the heavy filling material is also one of the structural resistance sources that can form a gravity structure as well.
  • the combining pillar is piled into a stratum or a base, so that the combining pillar forms a cantilever support, which is also one of the resistance sources to the structure and makes the structure as a cantilever structure.
  • the lattice unit of the light component is made of a light and high-strength material such as a polymer (resin), a metal base, an inorganic non-metal base composite, or an industrial plastic material, and both light component and heavy component require to have a hollow portion at the position of the tenon for passing through the combining pillar, and the lattices of the light component and the lattices of the heavy component may or may not have a hollow portion with the same factors of consideration, but the manufacture of the lattice unit of the heavy component does not require special processes, and general manpower can be used for the manufacture.
  • a light and high-strength material such as a polymer (resin), a metal base, an inorganic non-metal base composite, or an industrial plastic material
  • lattices of the lattice unit of the light component preferably construct a hollow portion.
  • the lattice unit of the light component in a construction can be transported and assembled by manpower due to the light weight of the lattice unit. Except special requirements, it is not necessary to employ additional hoisting machines, and the flexibility of adjusting the lattice units of the heavy component is much higher. In the meantime, a construction precision on the plane and height of the structure higher than those of the lattice units of the heavy component can be achieved.
  • the mass of the lattice unit of the light component produces a gravitational force which is insufficient to be one of the structural resistance sources
  • the constructed tenon joint type space lattice structure is a light structure
  • one of the structural resistance sources is a heavy filling material of a hollow portion of the structure, and the gravitational force produced by the heavy filling material is provided for forming a gravity structure.
  • the combining pillar is piled into a stratum or a base, and the combining pillar constitutes a cantilever support which is another source of the structural resistance for forming a cantilever structure.
  • the methods of transmitting forces between the components of a tenon joint type space lattice structure and a general space lattice structure are different, primarily residing on that the source of an external force and a support method of a structure.
  • the external force of a space lattice structure is generally the weight of the structure, the equipment and people carried by the structure, and the wind force, and the force is centralized for a support such as a pillar or a wall, and then transmitted into the stratum or base, and finally transmitted from the base to the stratum.
  • the external forces of the tenon joint type space lattice structure are primarily earth pressure, water impact force, and water tractive force.
  • the structure produces the gravitational force by the weights of the structure itself and the heavy filling material, and the friction produced by the gravitational force uses a distributed support method to resist the external forces.
  • the external force After an external force is exerted onto each combining pillar, the external force is transmitted directly into the stratum or base by the cantilever support of the combining pillar.
  • a distributed method is provided for resisting external forces, and such method can be used separately or used for the whole structure.
  • a shift is usually occurred between plane layers of each structure of the construction, which makes the construction of the combining pillar very difficult, and may even cause a different dynamic mode of each structural layer.
  • a combining pillar is built at a lower layer of the construction, and the combining pillar serves as a construction base for each plane layer along the direction of the height of the structure.
  • the lattice of the lattice unit does not come with a hollow portion, but is built on the lattices at the upper and lower layers of the lattice unit and corresponding to the convex tenon and the concave tenon groove, and the protruded tenon is embedded into the corresponding tenon groove in the tenon joint assembly, such that the lattices at upper and lower layers of the lattice unit so as to prevent the shift between layers.
  • the installation of accessory facilities is a feasible solution to achieve the same purpose.
  • the lattices of the lattice unit are installed in the hollow portion, and a specific quantity of accessory short pillars is used as a base for the assembling of the upper and lower layers of the structure along the direction of the height of the structure to prevent the occurrence of a shift between layers.
  • the invention can complete constructing a tenon joint type space lattice structure quickly and successfully, and soils and stones can be filled into the hollow portion of the structure for a large scale of vegetation. It is necessary to be aware of the strength of the tenon joint of the structure.
  • a rigid or flexible ring can be used for sheathing and connecting the combining pillar, and thus not only improving the strength of the tenon joint, but also enhancing the overall structural strength.
  • the lattice unit of the light component can be converted to a heavy component by filling a heavy filling material such as concrete into a light component in the hollow portion of the lattice to seal the bottom of the lattice.
