[0025] The technical scheme of the present application will be further described in detail below with specific embodiments and in combination with the drawings:

[0026] Embodiment 1

[0027] As Figure 1 With Figure 2 The embodiment of the support frame component of the present application comprises a hollow longitudinal support rod 1, a transverse support rod 2, an adapter rod 3, and a plug-in assembly 4. The longitudinal support rod 1 is two and oppositely arranged. The transverse support rod 2 is a plurality of rods. The plurality of transverse support rods 2 are arranged between the two longitudinal support rods 1 and the two ends are respectively connected with the two longitudinal support rods 1. The adapter rod 3 is detachably arranged on the top of the longitudinal support rod 1 through the plug-in assembly 4 and partially protrudes from the longitudinal support rod 1.

[0028] The present application utilizes the transverse support rod 2 to connect the longitudinal support rod 1, which can be arranged between the two longitudinal support rods 1 by welding and is arranged vertically, so that the two longitudinal support rods 1 form a whole, thereby improving the reliability of the whole. The longitudinal support rod 1 is the main load-bearing component of the support frame component and has high strength and good load-bearing capacity. The adapter rod 3 is connected with the longitudinal support rod 1 by using the plug-in assembly 4. The arrangement of the adapter rod 3 facilitates the splicing of different support frame components. In the splicing process, the longitudinal support rods 1 of different support frame components can be connected by the adapter rod 3 to realize splicing and building into a scaffold. In the actual building process, the support frame component of the present application can be used as a side part of the scaffold for support, and four support frame components can be used to build a tower type support frame, which is convenient and fast to build and greatly improves the construction efficiency. Moreover, in the storage process, the scaffold is disassembled into a side part for storage, which greatly saves the storage space and facilitates transportation.

[0029] As an improved scheme of the embodiment, the top of the transverse support rod 2 is provided with a convex or textured surface for anti-skid. In the construction, the erection and dismantling of the scaffold are completed by the scaffold workers, and the scaffold workers climb the installed scaffold beams to work and transfer materials. In the prior art, the tower support frame is usually welded by steel pipes, and the cross beam is a steel round pipe, which lacks anti-skid structure and has the problem of slipping when climbing, affecting the safety of the construction personnel. The transverse support rod 2 of the utility model serves as a cross beam, and the convex or textured surface provided at the top of the transverse support rod 2 can play an anti-skid role, thereby improving the safety of the scaffold workers in the construction process.

[0030] As an improved scheme of the embodiment, the adapter rod 3 is inserted into the longitudinal support rod 1, and the insertion assembly 4 is inserted through the longitudinal support rod 1 and the adapter rod 3. The adapter rod 3 is connected to the longitudinal support rod 1 through insertion, and preferably, the shaft diameter of the adapter rod 3 is slightly smaller than the shaft diameter of the longitudinal support rod 1, so that the adapter rod 3 is easily inserted into the longitudinal support rod 1. The insertion assembly 4 is used to connect the adapter rod 3 to the longitudinal support rod 1, so that the installation and disassembly of the adapter rod 3 are more convenient.

[0031] As an improved scheme of the embodiment, the insertion assembly 4 includes a plug pin 41 and a spring pin 42. The plug pin 41 is inserted into the longitudinal support rod 1 and the adapter rod 3, respectively. One end of the spring pin 42 is fixedly connected to one end of the plug pin 41, and the other end of the spring pin 42 is movably connected to the other end of the plug pin 41. The spring pin 42 is located on the side of the longitudinal support rod 1 and / or the adapter rod 3. The plug pin 41 is used for insertion into the adapter rod 3 and the longitudinal support rod 1, and the spring pin 42 is used for anti-dropping of the plug pin 41, which can improve the reliability of the connection between the adapter rod 3 and the longitudinal support rod 1.

Compared with the prior art in which a round pipe is used as a cross beam and a longitudinal beam, the cross sections of the transverse support rod 2 and the longitudinal support rod 1 of the utility model are square or regular polygonal, rather than the structure of a round pipe. On the one hand, this can prevent rotation and slipping, thereby improving the connection reliability. On the other hand, it can also improve the safety of the scaffold workers when they climb.

[0033] As an improved scheme of the embodiment, a protective cover 5 is further included.

[0034] Embodiment 2

[0035] The embodiment is an embodiment 2 of a support frame member, which is similar to the embodiment 1, and the difference is that a plurality of reinforcing rods 6 are further included, one end of the reinforcing rod 6 is connected with the longitudinal support rod 1, and the other end is connected with the transverse support rod 2. The reinforcing rod 6 is an obliquely arranged rod, which is used for reinforcing the transverse support rod 2 and the longitudinal support rod 1, improving the connection strength of the two, and increasing the anti-deformation ability.

[0036] As an improved scheme of the embodiment, two oppositely arranged reinforcing rods 6 form a group, and the two reinforcing rods 6 in the same group are symmetrically arranged about the central axis of the support frame member. The reinforcing rod 6 supports the transverse support rod 2 and the longitudinal support rod 1 from different positions, which can improve the integrity of the transverse support rod 2 and the longitudinal support rod 1, thereby increasing the overall strength and bending resistance. By symmetrically arranging the reinforcing rod 6, the stress of the longitudinal support rod 1 in the support frame member can be more balanced. By arranging a plurality of groups of reinforcing rods 6, the strength of the support frame member can be further improved.

[0037] Embodiment 3

[0038] As Figure 3 shown is an embodiment of a combined support frame of the utility model, which comprises a plurality of support frame members as described above, and the plurality of support frame members are sequentially connected to form a tower type support frame. The bottom of the support frame member of the upper layer is inserted with the top of the support frame member of the lower layer through the adapter rod 3, and is respectively inserted with the two layers of support frame members through the insertion assembly 4. Two oppositely arranged support frame members can form a layer of combined support frame unit, and another layer of combined support frame unit is used to connect the two layers of combined support frame units. Specifically, the longitudinal support rod 1 of the upper and lower layers of combined support frame units is inserted through the adapter, and then is locked and fixed through the insertion assembly 4, so that the connection of the two layers of combined support frame units can be realized. After the connection of the plurality of layers of combined support frame units, a stable tower type support frame can be formed.

[0039] As an improved scheme of the embodiment, the tower type support frame is an axisymmetric structure. The tower type support frame with the axisymmetric structure has more balanced stress, higher strength, and better anti-deformation ability.
