Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated round bamboo profile connected by a wire winding method. Background Technology

[0002] 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.

[0003] 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

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a simple, reliable, and easily industrialized assembled round bamboo profile using the wire winding method.

[0005] The technical solution of this utility model is: a wire-wound connection assembly round bamboo profile, including a round bamboo body and a connector, the connector being connected to both ends of the round bamboo body, and the connector being provided with multiple fixing rods; one end of the fixing rod is fixedly connected to the connector, and the other end is attached to the outer wall of the round bamboo body; the outer wall of the round bamboo body is provided with a winding layer, and the fixing rod is located between the round bamboo body and the winding layer.

[0006] Preferably, the end of the fixing rod away from the connector is L-shaped, and the round bamboo body has a plurality of first through holes along its radial direction for the fixing rod end to be inserted.

[0007] Preferably, the winding layer is formed by winding metal wire.

[0008] Preferably, the metal wire is selected from any one of steel wire, copper wire, and iron wire.

[0009] 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.

[0010] Preferably, the flange is provided with a slot, and the end of the fixing rod near the connector is fixedly connected to the flange through the slot.

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

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

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. This utility model proposes a wire-winding method for connecting prefabricated round bamboo profiles, which directly applies round bamboo materials 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. The external connection of the round bamboo profile is then achieved through the connector. This utility model has a simple structure, is easy to calculate, and is easy to standardize.

[0016] 3. The manufacturing process of this utility model is simple, and the connector, winding layer and round bamboo body can all be prefabricated, which is convenient for industrial production and can greatly reduce time and material costs.

[0024] like Figure 1-3 As shown: This utility model provides a wire-wound connection assembly-type round bamboo profile, including 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. One end of the fixing rod 3 is fixedly connected to the connector 2, and the other end is attached to the outer wall of the round bamboo body 1. The outer wall of the round bamboo body 1 is provided with a winding layer 4, and the fixing rods 3 are located between the round bamboo body 1 and the winding layer 4. This utility model achieves a fixed connection between the connector 2 and the round bamboo body 1 by setting the winding layer 4 to fix the fixing rods 3 to the cylinder. This connection method has a simple structure, is easy to calculate and standardize, and has a simple manufacturing process. Moreover, the connector 2, round bamboo body 1, fixing rods 3 and winding layer 4 can all be prefabricated, which can greatly reduce costs and facilitate industrial production.

[0025] Specifically, the end of the fixing rod 3 away from the connector 2 is L-shaped, and the round bamboo body 1 is provided with a plurality of first through holes along its radial direction for the end of the fixing rod 3 to be inserted. By inserting the end of the fixing rod 3 into the first through hole of the round bamboo body 1, the tightness between the fixing rod 3 and the round bamboo body 1 can be further strengthened, thereby indirectly enhancing the stability of the connection between the connector 2 and the round bamboo body 1.

[0026] Preferably, the winding layer 4 is formed by winding metal wire. More preferably, the metal wire is selected from any one of steel wire, copper wire, and iron wire. It is worth noting that using metal wire to form the winding layer 4 is the preferred solution of this embodiment. However, any other material on the market that can meet the strength requirements can also be used to form the winding layer 4.

[0027] Specifically, such as Figure 2 As shown, 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 the main body of the connector 2 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 main body of the connector 2. 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 end of the connecting screw shank is engaged in the cavity structure.

[0028] Specifically, such as Figure 4As shown, the flange has a slot 221, and the end of the fixing rod 3 near the connector 2 is fixedly connected to the flange 22 through the slot 221. The fixing rod 3 can be adjusted in the slot 221 to fit different diameters of the cylindrical bamboo body 1. In this embodiment, the fixed connection is preferably a screw connection, which facilitates disassembly and adjustment.

[0029] Preferably, such as Figure 5 As shown, in order to adapt to the connection node 5 used in this embodiment and save installation space, the support body 21 in this embodiment can be selected with a frustum-shaped or cylindrical outline.

[0030] The above description is a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this utility model, should be covered within the protection scope of the claims of this utility model.
