Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a support rod for a scaffold and a scaffold. Background Art

[0002] The disc-type scaffolding is also called the disk-type scaffolding, which includes vertical poles, horizontal poles and diagonal poles. There are eight holes on the disc-type scaffolding, four small holes are dedicated to the horizontal poles, and four large holes are dedicated to the diagonal poles. The support methods of the disc-type scaffolding under the building beams mainly include:

[0003] ① The beam and slab are supported separately, that is, the vertical poles directly support the bottom of the beam, and the top supports bear the load;

[0004] ② Beam and slab support together, see Figure 4 As shown, in the double-slot steel joist method, the crossbar 10 is connected to the vertical bar 20, and the buckle on the vertical bar 20 is used to support the double-slot steel structure 30. The double-slot steel structure 30 supports the beam S, and the buckle bears the beam load.

[0005] The above-mentioned method ① can be adopted by almost all support systems, especially the support under large-load beams. It is a relatively mature construction technology. However, the branch system uses more materials (independent support poles are added under the beams), which is not economically advantageous. Method ②: The buckle bracket is a special method for under the beam. The beam load is transferred to the buckle on the pole through the double-groove steel structure 30, and then the load is transferred to the pole. The disadvantage of this process is that the double-groove steel structure is relatively heavy, which is not advantageous for supports with low floor heights and small beam loads.

[0006] Therefore, a beam support structure that is easy to construct, economical and durable is needed. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a support rod and a scaffold for a scaffold, wherein the support rod can be fixedly connected to the vertical rod through a clamping portion, and can be used as a support under the beam, which is convenient for construction and low in cost.

[0008] In order to solve the above technical problems, the utility model provides a support rod for a scaffold, which includes: a connecting rod and a connecting piece arranged at the end of the connecting rod, the connecting piece includes two clamping parts that are rotatably connected and a locking piece that locks the two clamping parts, and an arc-shaped recess is provided on the clamping part. When the two clamping parts are locked and connected on the locking piece, the two recesses are connected to form a circular hole that is clamped with the upper pole of the scaffold.

[0009] Preferably, the clamping portion is provided with a protrusion extending in the radial direction, and the protrusion is provided with a bolt hole; the locking member is a bolt with a nut, and the bolt is passed through the bolt holes of the two clamping portions.

[0010] Preferably, the inner surface of the recess has anti-slip protrusions.

[0043] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0044] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology, and are not used to limit the conditions for implementation of the present invention. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose of the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0045] like Figure 1 and Figure 2 As shown, the present invention provides a support rod for a scaffold, which includes: a connecting rod 4 and a connecting member 1 provided at the end of the connecting rod, the connecting member 1 includes two rotatably connected clamping parts 14 and a locking member for locking the two clamping parts 14, the clamping parts 14 are provided with an arc-shaped recessed portion 102, and when the two clamping parts 14 are locked and connected by the locking member, the two recessed portions 102 are connected to form a circular hole 101 that is clamped to the vertical pole of the scaffold. In this embodiment, the two clamping parts 14 are rotatably connected by c15, which is opened and locked by the locking member; during scaffolding construction, the locking member can be opened to open the two clamping parts 14, so that the vertical pole can be placed in the circular hole 101 and then locked by the locking member, thus achieving the connection and fixation of the support rod, so that it can be used in the scaffold to support the beam.

[0046] For better locking connection, see Figure 2 As shown, the clamping portion 14 is provided with a radially extending protrusion 11 with a bolt hole. The locking member is a bolt 12 with a nut 13, which is inserted into the bolt holes of the two clamping portions. This embodiment uses the bolt and nut structure to quickly achieve relative rotation and locking of the clamping portion 14.

[0047] In order to better lock the support rod and the vertical rod, the inner surface of the recess 102 is provided with anti-slip protrusions. Figure 3 As shown, the anti-slip protrusion 103 is a threaded ridge; or a protruding bar structure, or an anti-slip member is fixed to the inner surface of the recess 102. Furthermore, the recess is a short tube structure 103 of a certain length. That is, the steel tube structure 103 can be formed by dissecting a steel tube made of the same material as the upright pole. The increased length increases the contact surface with the upright pole, improves wear resistance and anti-slip properties, and better locks to the upright pole.

[0048] As an embodiment, the above-mentioned connecting rod includes a first rod and a second rod (not shown) that are slidably connected and can be locked by a limit member. This embodiment can achieve adjustable length of the connecting rod, making its application scenarios more extensive; for example, it can also be used as a non-standard pitch diagonal rod tie and a break tension structure, reducing the use of non-standard pitch and break steel pipe fasteners.

[0049] The above-mentioned clamping part is a semi-ring structure with supporting ribs. After the connecting head is locked, it forms a disc shape, which is similar to the disc buckle on the scaffolding pole. The setting of the supporting ribs can make the clamping part itself more stable and easy to support.

[0050] As an example, see Figure 1As shown, a connector 2 is fixedly provided on the connecting rod 4, and the connector 2 is connected to the connecting member 1 via a limit pin 3. The connecting rod 4 with the connector 2 in this embodiment has the same structure as the crossbar in the scaffolding, so it does not require additional processing and design, and is easy to implement. The connector 2 includes a clamping portion with a hole, and the clamping portion 1 is a semi-ring structure with support ribs. The clamping portion 1 is clamped on the connecting member, and the limit pin 3 is passed through and positioned on the clamping portion and the clamping portion. The connection between the connecting rod 4 and the connecting member is not limited to this, and the two can also be directly welded and fixed without the need for an additional connector.

[0051] like Figure 5 As shown, the present application also provides a scaffold, which includes:

[0052] The scaffolding system includes vertical and horizontal vertical poles 20 and horizontal poles 10, each of which is provided with a buckle. The vertical poles 20 are provided with joints at both ends of the horizontal pole 10, and the vertical poles 20 and the horizontal pole 10 are fixedly connected by the joints and the buckle. The scaffolding system also includes a support rod 50 for a scaffold as described in any of the above items, and the two connecting members 1 in the support rod 50 are respectively fixedly connected to the two vertical poles 20. In this embodiment, the connecting member 1 is locked and fixed to the vertical pole 20, that is, the support rod can be directly supported under the beam S without being affected by the position of the buckle on the vertical pole. The connecting member 1 can be connected and fixed to a horizontal pole (i.e., the connecting rod 4) of a fixed length on the ground, and then tightened and fixed directly using the locking member after the elevation below the beam is determined.

[0053] More preferably, the scaffold further comprises an oblique support member diagonally connecting the vertical rods and the horizontal rods. The support rods in this embodiment can not only be used as a support beam structure, but also can be used as non-standard pitch diagonal rod tie-ties and break-joint tie-joint components, thereby reducing the use of non-standard pitch and break-joint steel pipe fasteners.

[0054] Therefore, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
