[0016] Figure 1 It is a three-dimensional view of the I-beam splicing device of the cantilever external scaffold provided by the present application. Detailed Embodiments

[0017] The present utility model will be further described in detail below in conjunction with the drawings through specific embodiments. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the field.

[0018] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean that they are necessary sequences, unless it is stated that a certain sequence must be followed.

[0019] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0020] When splicing I-beams, the ends of two I-beams are usually butted and welded together. Since the contact area between the two I-beams is small, the structural strength between the two connected I-beams is relatively low, and the cantilever external scaffold built in this way is prone to safety accidents.

[0021] In view of the above problems, the present application provides an I-beam splicing device for a cantilever external scaffold, which does not change the strength of the I-beam to ensure the strength of the built cantilever external scaffold and avoid the occurrence of safety accidents.

[0022] See Figure 1 As shown, the I-beam splicing device for a cantilever external scaffold provided by the present application includes: a body 10 and a fixing component 20.

[0023] An I-shaped splicing channel 11 is provided inside the body 10. The shape and size of the I-shaped splicing channel 11 are adapted to the shape and size of the I-beam. The I-shaped splicing channel 11 is used for two I-beams to be inserted from its two ends respectively.

[0024] The fixing component 20 is used to fix the parts of the two I-beams inserted into the I-shaped splicing channel 11 in the I-shaped splicing channel 11.

[0025] The I-beam splicing device for a cantilever external scaffold provided by the present application can fix the two spliced I-beams in the I-shaped splicing channel 11 through the fixing component 20. Compared with the previous method of butt welding, the fixing area can be increased to make the connection between the two I-beams more firm. Correspondingly, the cantilever scaffold made by this device is also more stable.

[0026] Since the web of the I-beam occupies a large area, only the web of the I-beam needs to be fixed. The fixing component 20 includes at least two first fasteners 21. At least two first locking holes 111 are provided in the abdomen of the I-shaped splicing channel 11. The at least two first locking holes 111 respectively correspond to the two I-beams. At least one first through hole is also provided on the webs of the two I-beams respectively. The first through hole corresponds to the first locking hole 111. The at least two first fasteners 21 respectively penetrate the corresponding first locking holes 111 and first through holes and are fastened to fixedly connect the abdomen of the I-shaped splicing channel 11 with the web of the I-beam.

[0027] In this embodiment, after the first fasteners 21 respectively penetrate the corresponding first locking holes 111 and first through holes and are fastened, the two I-beams inserted into the I-shaped splicing channel 11 from both ends can be fixedly connected with the I-shaped splicing channel 11.

[0028] In one embodiment of the present application, the fixing component 20 further includes at least two second fasteners 22. At least two second locking holes 112 are provided on the upper wing portion of the I-shaped splicing channel 11. The at least two second locking holes 112 respectively correspond to two I-beams. At least one second through hole is further provided on the upper wing plates of the two I-beams. The second through holes correspond to the second locking holes 112. The at least two second fasteners 22 respectively penetrate through the corresponding second locking holes 112 and second through holes and are fastened to fixedly connect the upper wing portion of the I-shaped splicing channel 11 with the upper wing plates of the I-beams.

[0029] By fixedly connecting the upper wing plates of the I-beams with the upper wing portion of the I-shaped splicing channel 11 through the second fasteners 22, the firmness of the connection between the I-beams and the I-shaped splicing channel 11 can be improved.

[0030] Furthermore, the fixing component 20 provided in this embodiment further includes at least two third fasteners 23. At least two third locking holes 113 are provided on the lower wing portion of the I-shaped splicing channel 11. The at least two third locking holes 113 respectively correspond to two I-beams. At least one third through hole is further provided on the lower wing plates of the two I-beams. The third through holes correspond to the third locking holes 113. The at least two third fasteners 23 respectively penetrate through the corresponding third locking holes 113 and third through holes and are fastened to fixedly connect the lower wing portion of the I-shaped splicing channel 11 with the lower wing plates of the I-beams.

[0031] In this embodiment, after fixedly connecting the web of the I-beam with the abdomen of the I-shaped splicing channel 11 through the first fastener 21, the upper wing plate of the I-beam is fixedly connected with the upper wing portion of the I-shaped splicing channel 11 through the second fastener 22, and the lower wing plate of the I-beam is fixedly connected with the lower wing portion of the I-shaped splicing channel 11 through the third fastener 23, so that the two I-beams can be firmly connected through the I-shaped splicing channel 11.

[0032] In one embodiment of the present application, the at least two second locking holes 112 and the at least two third locking holes 113 respectively correspond one by one, and the correspondingly corresponding second locking holes 112 and third locking holes 113 are located on the same straight line. Thus, the second fasteners 22 and the third fasteners 23 respectively penetrating through the correspondingly corresponding second locking holes 112 and third locking holes 113 can be the same fastener.

[0033] In this embodiment, the first fastener 21, the second fastener 22 and the third fastener 23 are all high-strength bolts, and can be locked by nuts after passing through the corresponding locking holes and through holes. Thus, they can be disassembled, which is convenient for the turnover and repeated use of the I-beams and the I-beam splicing device of the cantilevered external scaffold, and further reduces the construction cost.

[0034] Continue to refer to Figure 1As shown, two second locking holes 112 are respectively arranged on both sides of the upper wing part of the I-shaped splicing channel 11, and the two second locking holes 112 correspond to the upper wing plate of an I-beam. Two third locking holes 113 are respectively arranged on both sides of the lower wing part of the I-shaped splicing channel 11, and the two third locking holes 113 correspond to the lower wing plate of an I-beam. In this way, four second locking holes 112 and four second locking holes 113 can be arranged on the I-shaped splicing channel 11, and the corresponding second locking holes 112 and third locking holes 113 can be penetrated by the same fastener for locking.

[0035] Of course, one second locking hole 112 is respectively arranged on both sides of the upper wing part of the I-shaped splicing channel 11, and the one second locking hole 112 corresponds to the upper wing plate of an I-beam, and the second locking holes 112 on both sides are arranged diagonally. One third locking hole 113 is respectively arranged on both sides of the lower wing part of the I-shaped splicing channel 11, and the one third locking hole 113 corresponds to the lower wing plate of an I-beam, and the third locking holes 113 on both sides are arranged diagonally.

[0036] This embodiment also provides a cantilever external scaffold, including: the I-beam splicing device of the cantilever external scaffold in the above embodiment, and further including multiple groups of I-beam groups. Each I-beam group includes two I-beams, and the two I-beams are respectively inserted into the I-shaped splicing channel 11 from both ends of the I-shaped splicing channel 11 and fixed by the fixing component 20.

[0037] In summary, for the cantilever external scaffold and its I-beam splicing device provided by the present application, the two spliced I-beams are fixed in the I-shaped splicing channel through the fixing component. Compared with the previous method of butt joint and welding, the fixing area can be increased, so that the connection between the two I-beams is more firm. Correspondingly, the cantilever scaffold made by this device is also more stable.

[0038] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or replacements can also be made.
