[0025] In order to better understand the technical scheme of the utility model, the utility model will be described in detail below in conjunction with the drawings.

[0026] In the embodiment 1 of the cantilevered scaffold structure (hereinafter referred to as scaffold) in the utility model, the scaffold comprises a cantilevered I-beam 102 for anchoring on a structural ground beam 109 of the original ground 101, and the cantilevered I-beam 102 is fixedly connected with the structural ground beam 109 of the ground through an anchor 104.

[0027] In the embodiment, the scaffold comprises a cantilevered I-beam 102 for anchoring on a structural ground beam 109 of the original ground 101, and the cantilevered I-beam 102 is fixedly connected with the structural ground beam 109 of the ground through an anchor 104. For the riverfront building, the structural ground beam 109 is often located at the edge position of the ground, and there is no fixed structure for installation outside, therefore, for the cantilevered I-beam 102, the position of the structural ground beam 109 is taken as the demarcation line, the part of the solid ground inside is the fixed section fixed on the ground, and the part suspended out of the ground is the cantilevered section.

[0028] Specifically, the configuration structure includes a counterweight rod 103 fixedly arranged on the upper surface of the end of the fixed section away from the cantilever section by a fastening bolt 105, the counterweight rod 103 is also in the form of an I-beam, the counterweight rod 103 is arranged perpendicularly to the cantilever I-beam 102, and the counterweight rod 103 is symmetrically arranged relative to the cantilever I-beam 102. The counterweight rod 103 is fixedly arranged with a counterweight block 107, the gravity of the counterweight block 107 is applied to the counterweight rod 103, and finally a downward force moment is applied to the fixed section of the cantilever I-beam 102, that is, even if the cantilever I-beam 102 has only one fixed point relative to the ground, the problem of overturning around the anchoring point due to the large weight on the cantilever section after the erection is completed can also be avoided. It is worth noting that the weight of the counterweight block 107 is related to the length of the cantilever section and the design load, and the mass of the counterweight block 107 can be calculated before use to obtain a reasonable mass. The counterweight block 107 is a reinforced concrete pre-block, and the weight and shape of the pre-block can be selected according to actual needs, and the process is simple. The counterweight rod 103 is arranged on the upper surface of the cantilever I-beam 102, and the cantilever I-beam 102 is arranged on the ground, so that the counterweight rod 103 is arranged in a spaced manner between the ground, and a support structure is further arranged between the counterweight rod 103 and the ground. Specifically, the support structure is a square wood 112 arranged below the counterweight rod 103, and the length of the square wood 112 is equivalent to the length of the counterweight block 107. Of course, in other embodiments, the support structure can also be fixedly arranged on the lower surface of the counterweight rod. Alternatively, in other embodiments, when the position of the fixed section on the ground has the possibility of anchoring, the fixed section is anchored by the traditional form of drilling and gluing, and the counterweight structure is arranged again to enhance the reliability of the structure.

[0029] In order to limit the position of the counterweight block 107, the counterweight rod 103 is provided with a vertically arranged limiting rod 106, and the center of the counterweight block 107 is provided with a limiting hole matched with the limiting rod 106. Specifically, the limiting rod 106 is a square tube welded on the counterweight rod 103, and the limiting hole is a square hole matched therewith, so as to be rotationally matched with the counterweight block 107, thereby enhancing the firmness of the counterweight block 107 on the counterweight rod 103 and preventing pedestrians from moving it during construction. Along the extension direction of the counterweight rod 103, four limiting rods 106 are sequentially arranged on the upper surface of the counterweight rod 103, and the four limiting rods 106 are symmetrically arranged in two groups about the cantilever I-beam 102. In use, the counterweight can be used as needed, such as using only the outermost two limiting rods or using only the innermost two limiting rods or using all four limiting rods. Alternatively, in other embodiments, the limiting rods can also be arranged in six or eight or other numbers.

[0030] The stability of the counterweight 107 is the basis of the stability of the whole scaffold, in order to avoid the damage of the counterweight 107 by human in the construction process, the two sides of the counterweight 107 and the weight rod 103 are provided with the lifting ring for wearing the steel wire rope 108, when the plurality of counterweights 107 are stacked in the up-down direction, the positions of the lifting rings on the counterweights 107 also correspond, which is convenient for wearing and installing the steel wire rope 108. The wearing ring on the weight rod 103 can be arranged on the body of the weight rod 103 or the limiting rod 106, which is determined according to the actual demand. When the steel wire rope 108 is used for fixing, the steel wire rope 108 is first worn through the lifting ring on the counterweight 107 and finally worn through the lifting ring on the weight rod 103, which not only can realize the connection of the plurality of counterweights 107, but also can fix the counterweight 107 on the weight rod 103, avoid the artificial moving or the artificial intentional damage, and improve the safety performance.

[0031] Finally, in order to further improve the safety performance of the scaffold, the scaffold further comprises a suspension support for fixing on the building, the suspension support is used for fixing on the surrounding building, the position of the suspension support is higher than the height of the cantilever I-beam 102, the inclined cable 110 for pulling the cantilever section is arranged between the suspension support and the cantilever section, the cantilever I-beam 102 is conveniently secondarily supported through the inclined cable 110, and the overturning is avoided.

[0032] It should be clear that the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.
