Description

Technical Field

[0001] This invention relates to the field of architectural structural design, specifically a prefabricated steel cylinder semi-rigid non-destructive wood structure node. Background Technology

[0002] With its unique advantages such as being lightweight, comfortable, energy-efficient, and pollution-free, wood is receiving increasing attention and use in construction.

[0003] However, wood is an anisotropic material, with significant differences in mechanical properties between the grain direction and the cross-grain direction. Currently, the common joint connection methods used in wood structures, such as mortise and tenon joints and bolted connections, usually require grooving and drilling inside the wood components, which can cause significant internal damage to the wood components and easily lead to splitting problems at the ends of the components or even the entire components, negatively impacting the load-bearing capacity and durability of the wood structure in the later stages. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated steel cylinder semi-rigid non-destructive wood structure joint to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A prefabricated steel cylinder semi-rigid non-destructive wood structure joint, the structural joint comprising:

[0007] I-beam, the I-beam including flanges and web;

[0008] A column sleeve connected to the flange on the side away from the web;

[0009] A slotted frame detachably connected to the flange;

[0010] Mounting components connected to the slot frame;

[0011] Among them, stiffening plates are provided between the flanges of the I-beam in the direction along the web and in the direction perpendicular to the web.

[0012] As a further embodiment of the present invention, the mounting component includes:

[0013] A partition plate welded to the side of the slot frame away from the column sleeve;

[0014] The beam sleeve is welded to the side of the partition away from the slot frame.

[0015] As a further embodiment of the present invention, the flange and the slot frame are provided with pre-set through holes that cooperate with each other, and the through holes are used to detachably connect the flange and the slot frame with a bolt and nut structure.

[0016] As a further embodiment of the present invention, the I-beam, column sleeve, channel frame, partition plate and beam sleeve are all made of steel.

[0017] As a further embodiment of the present invention, the slot frame is externally enclosed by an I-beam.

[0018] As a further embodiment of the present invention, the slot frame is embedded in the I-beam.

[0019] As a further aspect of the present invention, the types of the channel frame include C-shaped steel and U-shaped steel.

[0020] As a further embodiment of the present invention, the length of the column sleeve is one-third to one-fifth of the length of the column to be connected, and the length of the beam sleeve is one-third to one-fifth of the length of the beam to be connected.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention connects wooden components at nodes using a socket joint method, avoiding damage to the ends of beams, columns, and other components caused by traditional connection methods such as mortise and tenon joints, thus enhancing the strength and durability of the components. Furthermore, it limits the movement of wooden components during installation, effectively preventing internal stress problems. Moreover, to meet connection requirements, it eliminates the need for processing wooden components, effectively improving installation efficiency and quickly and efficiently achieving effective connections between columns and beams. Specifically, this invention can also enhance the rigidity and integrity of wooden structures, and significantly improve their seismic resistance. Attached Figure Description

[0035] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0036] Please see Figures 1 to 7 In this embodiment of the invention, a prefabricated steel cylinder semi-rigid non-destructive wood structure node is provided, the structural node comprising:

[0037] The I-beam 4 includes a flange 2 and a web 3. It is worth mentioning that designing the beam at the node as an I-beam can fully utilize the mechanical properties of the material and effectively reduce the weight of the prefabricated steel cylinder node. Furthermore, in practical applications, the ratio between the width of the flange 2 and the height of the web 3 needs to be specifically designed with different ratios.

[0038] A column sleeve 1 connected to the flange 2 on the side away from the web 3; the column sleeve 1 has two ends, namely an upper column sleeve 1 and a lower column sleeve 1, for connecting with the support column; the connection between the flange 2 and the column sleeve 1 is generally by welding.

[0039] A slot frame 5 is detachably connected to the flange 2; the slot frame 5 can be externally wrapped around the I-beam 4 or internally embedded in the I-beam 4; the slot frame 5 is a C-shaped slot plate or a U-shaped slot plate;

[0040] A mounting assembly is detachably connected to the flange 2; the function of the mounting assembly is to connect the wooden beam, which is connected to the node via the mounting assembly.

[0041] Among them, stiffening plates 8 are provided between the flanges 2 in the direction along the web 3 and perpendicular to the web 3. Generally, the reference plane corresponding to the stiffening plate 8 is perpendicular to the reference plane corresponding to the flange 2. The angle between the reference plane corresponding to the stiffening plate 8 and the reference plane corresponding to the web 3 can be arbitrarily set. The two most common situations are: one is that the reference plane corresponding to the stiffening plate 8 is perpendicular to the reference plane corresponding to the web 3, and the other is that the reference plane corresponding to the stiffening plate 8 is parallel to the reference plane corresponding to the web 3. For the parallel case, refer to the appendix. Figure 8 .

[0042] The function of stiffening plates is to enhance the strength and stiffness at the joints. Since the vertical load on the column will be transferred to the I-beam, and the transverse section of the web of the I-beam is only a thin layer, it is very easy to become unstable and fail. Therefore, the installation of stiffening plates is a necessary technical feature.

[0043] Furthermore, the installation components include:

[0044] A partition plate 6 is welded to the side of the slot frame 5 away from the column sleeve 1;

[0045] The beam sleeve 7 is welded to the side of the partition 6 away from the slot frame 5.

[0046] In one embodiment of the technical solution of the present invention, the partition 6 is welded to one end of the beam sleeve 7 to form a one-way open space, and then the wooden beam is placed in the space; the partition 6 is welded to one end of the slot frame 5, and then the slot frame 5 is connected to the flange 2, thereby realizing the non-destructive connection of the beam and column.

[0047] In one embodiment of the technical solution of the present invention, a buffer component is often added to the space with the one-way opening to protect the end of the wooden beam.

[0048] As a preferred embodiment of the technical solution of the present invention, both the flange 2 and the slot frame 5 are provided with through holes of the same size, and the through holes are used to detachably connect the flange 2 and the slot frame 5 with bolts and nuts.

[0049] Bolt and nut connection is the most common detachable connection method, and its operation process is relatively simple; if the through hole is replaced with a bolt hole and then screws are used to achieve a detachable connection, it is also a feasible technical solution.

[0050] The advantage of using screws is that they are easier to install. The disadvantage is that it is difficult to make the flange 2 and the slot 5 fit tightly together. For example, if there is a height difference between the flange 2 and the slot 5, when the screws are connected, the screws will mate with the threaded holes on the flange 2 and the slot 5 respectively. At this time, the height difference will always exist, and the screws cannot reduce the distance between the flange 2 and the slot 5. When subjected to external force, the external force will act indirectly on the threads of the screws, which can easily cause rigid failure. Therefore, a bolt and nut structure is more suitable.

[0051] In a preferred embodiment of the technical solution of this invention, the I-beam 4, column sleeve 1, channel frame 5, diaphragm 6, and beam sleeve 7 are all made of steel. Steel is the most cost-effective material in the field and is also the most common material currently. In practical applications, other materials with different properties, such as alloys, can be selected depending on the specific circumstances. The material selection process is closely related to the progress of materials engineering. If more suitable materials emerge in the future, this application will also keep pace with the times and replace the I-beam 4, column sleeve 1, channel frame 5, diaphragm 6, and beam sleeve 7 with new materials.

[0052] In a preferred embodiment of the technical solution of the present invention, the length of the column sleeve 1 is one-third to one-fifth of the column to be connected, and the length of the beam sleeve 7 is one-third to one-fifth of the beam to be connected.

[0053] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
