Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a rod-type connected prefabricated round bamboo profile. Background Technology

[0002] Bamboo is an eco-friendly natural material, and its proper application is of great significance for energy conservation and emission reduction. Round bamboo is a hollow, circular rod with varying diameters at both ends, posing challenges to the connection technology of prefabricated round bamboo profiles. Solving the connection problem of round bamboo in engineering applications is a key issue in its application.

[0003] Traditional methods of connecting round bamboo profiles are relatively primitive, primarily using binding methods such as bamboo strips, hemp rope, or metal hoops. While these methods are simple to manufacture, they also have significant drawbacks. The varying diameters of the bamboo and different connection techniques introduce uncertainty into design, processing, and material selection, making it difficult to guarantee project quality. Furthermore, these round bamboo connection methods are labor-intensive and inefficient, hindering their widespread application in engineering projects. The "Safety Technical Specification for Bamboo Scaffolding in Building Construction" (JGJ 254-2011) in my country's construction industry standard specifies bamboo strip binding as the connection method for round bamboo. However, the "Technical Specification for Round Bamboo Structure Buildings" (CECS 434:2016) issued by the China Construction Industry Association specifies steel hoop binding and steel section + bolt connection methods for round bamboo.

[0004] Overseas, some manufacturers use round bamboo profiles (with steel sleeves at the ends of the bamboo profiles or a method of filling with cement and steel bolts) + special metal connecting plates. These connection methods have many joint specifications, are more complex to manufacture, and are not suitable for industrial production. Another connection method uses prefabricated round bamboo profiles with tapered heads + steel bolt balls. This connection method is more complex to manufacture, has poor assembly standardization, and is more expensive. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rod-type connection assembly round bamboo profile that is simple in structure, reliable, and easy to industrialize.

[0006] The technical solution of this utility model is: a rod-type connected assembled round bamboo profile, including a round bamboo body and a connector, wherein the connector is connected to both ends of the round bamboo body, and the connector is provided with multiple fixing rods; a metal disc is sleeved on the round bamboo body, and the metal disc is fixedly connected to the round bamboo body; one end of the fixing rod is fixedly connected to the connector, and the other end is fixedly connected to the metal disc.

[0007] Preferably, the connector includes a flange, a connecting screw, and a support body. The flange and the support body are fitted together to form a connector body with a cavity structure. The support body has a second through hole for the connecting screw to pass through. The connecting screw is rotatably connected to the connector body. The nut of the connecting screw is located inside the cavity, and the screw shaft is located outside the cavity structure.

[0008] Preferably, the flange is provided with a plurality of second connection holes, and the fixing rod is fixedly connected to the flange through the second connection holes.

[0009] Preferably, the metal disc is provided with a first connecting hole, and the end of the fixing rod away from the connector is fixedly connected to the metal disc through the first connecting hole.

[0010] Preferably, a wedge-shaped block is provided between the metal disc and the round bamboo body, and the material of the wedge-shaped block is preferably bamboo.

[0011] Preferably, the outer contour of the support is frustum-shaped.

[0012] Preferably, the outer contour of the support is cylindrical.

[0014] 1. This utility model proposes a rod-type connection prefabricated round bamboo profile, which directly applies round bamboo to prefabricated building structures, solving both the problem of difficult connection between round bamboo and the cost problem of bamboo processing.

[0015] 2. This utility model can tightly bond the fixing rod and the round bamboo body together through the winding layer, forming a tight connection structure between the connector and the round bamboo body.

[0026] like Figure 1-4 As shown: A rod-type connected assembled round bamboo profile includes a round bamboo body 1 and a connector 2. The connector 2 is connected to both ends of the round bamboo body 1, and multiple fixing rods 3 are provided on the connector 2. A metal disc 4 is fitted on the round bamboo body 1, and the metal disc 4 is fixedly connected to the round bamboo body 1. One end of the fixing rod 3 is fixedly connected to the connector 2, and the other end is fixedly connected to the metal disc 4. This utility model forms a fixed connection structure between the connector 2 and the round bamboo body 1 through the fixing rods 3, so that the round bamboo body 1 can be directly connected to the external threaded hole through the connector 2. This connection structure is simple, the force is clear, it is easy to calculate and standardize, the manufacturing process is simple, and the connector 2, round bamboo body 1, fixing rods 3 and metal disc 4 can all be prefabricated, which can greatly reduce costs and facilitate industrial production.

[0027] Furthermore, during installation, the metal disc 4 can be engaged with the bamboo joints of the round bamboo body 1, further enhancing the stability of the fixed connection between the metal disc 4 and the round bamboo body 1.

[0028] Specifically, the connector 2 includes a flange 22, a connecting screw 23, and a support body 21. The flange 22 and the support body 21 are fitted together to form a connector 2 body with a cavity structure. The support body 21 is provided with a second through hole for the connecting screw 23 to pass through. The connecting screw 23 is rotatably connected to the connector 2 body. The nut of the connecting screw 23 is located inside the cavity, and the screw shank of the connecting screw 23 is located outside the cavity structure. That is, the diameter of the second through hole is larger than the diameter of the threaded shank of the connecting screw 23 and smaller than the diameter of the nut of the connecting screw 23, so that the nut of the connecting screw shank is engaged in the cavity structure.

[0029] Preferably, the flange 22 is provided with a plurality of second connection holes 24, and the fixing rod 3 is fixedly connected to the flange 22 through the second connection holes 24. In this embodiment, the connection is specifically screwed.

[0030] Preferably, the metal disk 4 is provided with a first connecting hole 41, and the end of the fixing rod 3 away from the connector 2 is fixedly connected to the metal disk 4 through the first connecting hole 41. In this embodiment, a screw and a nut are used for screw connection; Figure 5 As shown, a wedge-shaped block 6 is provided between the metal disc 4 and the round bamboo body 1. When the fixing rod 3 is under tension, the fixing rod 3 will drive the metal disc 4 to apply a downward pressure to the wedge-shaped block 6, and the wedge-shaped block 6 will also apply an upward reaction force to the metal disc 4, so that a pre-tightening force is formed between the metal disc 4, the wedge-shaped block 6 and the round bamboo body 1, so as to enhance the connection stability between the metal disc 4 and the round bamboo body 1.

[0031] Furthermore, such as Figure 6 As shown, the wedge-shaped block 6 can be set at the bamboo node of the round bamboo body and abut against the bamboo node to prevent the wedge-shaped block 6 from sliding under force. The wedge-shaped block 6 can be directly cut from bamboo or wood, or it can be cast from metal.

[0032] Preferably, such as Figure 7 As shown, in order to adapt to the connection node 5 that works with this embodiment and save installation space, the support body 21 in this embodiment can be selected with a frustum-shaped or cylindrical outline.
