Description

Technical Field

[0001] The utility model relates to the field of building scaffolds, and more specifically, to a cantilever scaffold. Background Art

[0002] Cantilever scaffolding is generally used in the main body or decoration engineering of building construction. The supporting structure of existing cantilever scaffolding is basically a steel plate of fixed length, which cannot support cantilever scaffolding of different sizes. On the construction site, cantilever scaffolding of different sizes is often required, and the only way is to replace the suitable cantilever scaffolding supporting structure, which seriously reduces the construction efficiency. For example, the cantilever scaffolding supporting structure disclosed in the utility model patent with announcement number CN220100590U and the name of adjustable supporting structure of flower basket type cantilever scaffolding includes a lower support and a flower basket bolt member, the lower support is connected to the other end of the flower basket Luoshan by a lower tie rod, the lower support includes a lower support seat and an I-beam, one end of the I-beam is a rotating end, and the rotating end and the lower support seat are connected by bolts to swing and adjust, and the rotating surface of the rotating forging relative to the lower support seat is provided with a locking rib for rotation locking. Although this technical solution realizes the angle adjustment of the support structure in the horizontal direction, it still cannot overcome the defect of not being able to support cantilever scaffolding of different sizes.

[0003] In order to overcome the defect that the supporting structure of the existing cantilever scaffolding cannot be adapted to cantilever scaffoldings of different sizes, many people have proposed different cantilever scaffoldings. For example, the utility model patent with announcement number CN219622216U and name of a basket-type cantilever scaffold convenient for adjusting the spacing between inner and outer uprights discloses a basket-type cantilever scaffold convenient for adjusting the spacing between inner and outer uprights, which overcomes the defect that the supporting structure of the cantilever scaffolding cannot be adapted to cantilever scaffoldings of different sizes by arranging two movable positioning piles 9 on the cantilever steel; another example is the utility model patent with announcement number CN218912196U and name of a basket-type cantilever frame structure discloses a basket-type cantilever frame structure, which overcomes the defect that the supporting structure of the cantilever scaffolding cannot be adapted to cantilever scaffoldings of different sizes by arranging two positioning sleeves on the cantilever steel beam. The above methods for overcoming the defect that the supporting structure of the cantilever scaffolding cannot adapt to cantilever scaffoldings of different sizes are all achieved by setting adjustable positioning parts on the cantilever steel beam. Although the above defects can be overcome to a certain extent, the following problems are brought about. First, in order to adapt to large-sized scaffolding, the length of the cantilever steel beam is generally set to be longer. When the construction space is limited, the cantilever scaffolding cannot be installed; second, when setting the scaffolding protection structure, the cost of the protection structure is increased due to the longer cantilever steel beam; third, the adjustable positioning parts also require a positioning locking structure. For example, a utility model patent with announcement number CN218912196U and name of a flower basket type cantilever frame structure discloses a flower basket type cantilever frame structure. In order to lock the positioning parts, a positioning seat is set on the cantilever steel beam, and a driving mechanism is provided to drive the positioning seat to move along the length direction of the cantilever steel beam. The adjusting part has a complex structure and high manufacturing cost. Utility Model Content

[0029] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0030] like Figures 1 to 8 As shown, the utility model provides a cantilever scaffolding, comprising:

[0031] The main support is horizontally arranged, and includes a telescopic outer frame 3 and a telescopic inner frame 2 arranged in an inserted manner, one end of the main support is connected to the building body, and a scaffolding support 4 is respectively provided on the telescopic outer frame and the telescopic inner frame;

[0032] The auxiliary support has one end connected to the main body of the building and the other end connected to the other end of the main support to form a V-shaped structure, so that the main support can support cantilever scaffolds of different sizes.

[0033] In the above technical solution, the cantilever scaffolding includes a scaffolding and a scaffolding support structure, the scaffolding support structure includes a main support and an auxiliary support, the main support includes a telescopic outer frame 3 and a telescopic inner frame 2 which are inserted in a telescopic manner, the telescopic outer frame 3 and the telescopic inner frame 2 are telescopically arranged, and a scaffolding support 4 is respectively provided on the telescopic outer frame 3 and the telescopic inner frame 2 for installing the vertical poles of the scaffolding 7, and as the distance between the overlapping parts of the telescopic outer frame 3 and the telescopic inner frame 2 changes, the distance between the two scaffolding supports 4 also changes accordingly, so as to install scaffolds of different sizes, and the main support is arranged as The telescopic structure effectively avoids the need to set up a long supporting structure when using a smaller scaffold, thereby enhancing the adaptability of the cantilever scaffold in a limited construction space and the turnover of the construction site, improving the construction efficiency, and is particularly suitable for construction sites with a tight construction period; one end of the auxiliary support is arranged on the building body, and the other end is connected to the other end of the main support to form a ready-made V-shaped structure, which is used to realize the change of the length of the main support and ensure the supporting strength of the main support to the scaffold 7 within the length change range. The present application discloses two preferred structures of the auxiliary support, one is as follows Figures 1 to 4 As shown, the auxiliary support is arranged on the support frame structure below the main support, and the second is as shown Figures 5 to 8 As shown, the auxiliary support is arranged on a basket bolt connection structure above the main support.

[0034] In the above technical solution, the installation steps of the cantilever scaffolding are as follows:

[0035] Step 1: Set up a reasonable telescopic outer frame 3 and a telescopic inner frame 2 to assemble into the main support;

[0036] Step 2: Connect one end of the main support to the main building;

[0037] Step 3: Setting an auxiliary support, one end of the auxiliary support is connected to the building body, and the other end is connected to the main support to form a V-shaped structure with the main support;

[0038] Step 4: adjust the relative positions of the telescopic outer frame 3 and the telescopic inner frame 2, set a reasonable distance between the uprights of the scaffolding 7, and install the scaffolding 7.

[0039] like Figures 1 to 4As shown, in one of the technical solutions, the auxiliary support is arranged below the main support, and includes a support frame 11 with one end hinged to the other end of the main support and a support frame mounting plate 12 arranged on the main body of the building. The other end of the support frame 11 is movably connected to the support frame mounting plate 12. As a preferred structure of the auxiliary support, the auxiliary support includes a support frame 11 with one end hinged to the other end of the main support, which gives a supporting force to the main support from below the main support. The support frame 11 and the support frame mounting plate 12 arranged on the main body of the building are movably connected up and down. As the main support 11 is extended, the connection point between the support frame 11 and the support frame mounting plate 12 is moved downward, and as the main support 11 is shortened, the connection point between the support frame 11 and the support frame mounting plate 12 is moved upward, thereby realizing the adjustable length of the main support and ensuring the supporting strength of the main support to the scaffolding 7.

[0040] Figures 1 to 4 As shown, in one of the technical solutions, the specific setting method in which the other end of the support frame 11 is movably connected to the support frame mounting plate 12 is: a plurality of hooks are arranged in the vertical direction on the support frame mounting plate 12, and a hanging ring adapted to the hook is arranged on the other end of the support frame 11, and the other end of the support frame 11 is hung on hooks at different heights through the hanging ring to meet the requirements of changes in the main support length.

[0041] Figures 1 to 4 It can be seen that in one of the technical solutions, one end of the support frame 11 is hinged to the other end of the main support through the ear plate 10, so as to realize the hinge connection between the support frame 11 and the other end of the main support. When the length of the main support changes, the coordinated auxiliary support adaptively changes the angle with the main support and the connection height with the building body.

[0043] like Figures 5 to 8 In one of the technical solutions, the second steel wire rope 9 is arranged between the two scaffold supports 4 through the steel wire rope mounting plate 5, which does not affect the installation of the scaffold 7 and ensures the effective variable length of the main support.

The telescopic outer frame 3 and the telescopic inner frame are fixed at a certain length by high-strength bolts, without the need for a complex locking structure, which increases the manufacturing cost of the cantilever scaffolding and improves the requirements for the manufacturing process of the cantilever scaffolding.

[0045] like Figures 1 to 8 As shown, in one of the technical solutions, the main support is connected to the building body through the main support mounting plate 8, and the main support mounting plate 8 is fixed to the building body through high-strength bolts 1. The main support mounting plate 8 serves as the mounting surface of the main support and is connected to the building body through the high-strength bolts 1, thereby ensuring the strength of the main support.

[0046] like Figure 3 and Figure 7 As shown, in one of the technical solutions, the telescopic outer frame 3 is connected to the building body, the telescopic outer frame 3 and the telescopic inner frame 2 are both I-beams, and the telescopic inner frame 2 is inserted into the telescopic outer frame 3 to enable the telescopic inner frame 2 to be pulled relative to the telescopic outer frame 3, thereby achieving the adjustable length of the main support.

[0047] like Figure 1 and Figure 5 In one of the technical solutions shown, the telescopic inner frame 2 is connected to the building body, the telescopic inner frame 3 is a channel steel, the telescopic outer frame is an I-beam, and the telescopic inner frame 2 is inserted into the telescopic outer frame 3 to enable the telescopic outer frame 3 to be pulled relative to the telescopic inner frame 2, thereby achieving the adjustable length of the main support.
