Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a bidirectional force-bearing foundation section of an attached lifting scaffold. Background Art

[0002] Attached lifting scaffolding in construction is a special type of lifting machinery with vertical lifting and transport capabilities. Its uniqueness lies in the fact that it is erected around the perimeter of a building, requiring elevation and lowering operations as construction progresses. It also possesses a fixed-height, suspended, integrated structure. Specifically, it must comprise a vertically extending main frame and horizontally extending load-bearing trusses. As lifting and lowering are driven by lifting equipment dispersed throughout the building, the overall structure must maintain synchronization and consistency. Otherwise, uneven localized force distribution can lead to excessive stress concentration, resulting in accidents such as falls and overturning.

[0003] In the prior art, for example, Chinese patent CN201915616U discloses an improved bidirectional force-bearing foundation section for an attached lifting scaffold. In a rectangular hexahedron frame structure composed of two upper and lower parallel transverse rod-like members, two left and right parallel front and rear longitudinal rod-like members, and two front and rear parallel vertical rod-like members, at least one pair of non-adjacent endpoints in a plane formed by adjacent rod-like members are connected with a diagonal brace. The upper and lower ends of the vertical rod-like members are respectively provided with a vertical connection structure, and the two ends of the transverse rod-like members are respectively provided with a transverse connection structure. This foundation section can make the force distribution of the lifting force more reasonable and scientific, with better bidirectional force-bearing performance against bending moment and torque, and can achieve standardized construction of the vertical main frame and horizontal support trusses of the attached lifting scaffold installed with standard sections.

[0004] In the above patent, the base section can make the force distribution of the lifting force more reasonable and scientific, and has better two-way force resistance performance of bending moment and torque resistance. However, when lifting the base section, it is not convenient to connect the hook of the mechanical lifting equipment, which makes it inconvenient during lifting. Utility Model Content

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a bidirectional force-bearing foundation section of an attached lifting scaffold, comprising: four uprights, the four uprights being divided into two groups, two cross columns being symmetrically installed between the outer surfaces of the uprights in the two groups, a plurality of the cross columns being divided into two groups, two side columns being symmetrically installed between the outer surfaces of the cross columns in the two groups, wherein the outer surfaces of the two side columns are both provided with auxiliary components;

[0007] The auxiliary component includes an upper connecting block and a lower connecting block, and a plurality of fixing parts are provided between the outer surfaces of the upper connecting block and the lower connecting block. The outer surface of the upper connecting block is fixedly connected to a fixing rod, and the top of the fixing rod is fixedly connected to a hanging ring.

[0008] Preferably, the outer surface of the hanging ring is symmetrically fixedly connected with reinforcing ribs, and the two reinforcing ribs are both fixedly connected to the outer surface of the side column.

[0009] Preferably, first reinforcing rods are installed on the outer surfaces of the two side columns, and the bottoms of the two first reinforcing rods are fixedly installed on the outer surfaces of the two columns respectively.

[0010] Preferably, the outer surfaces of two of the side columns and the transverse column are fixedly connected with second reinforcing rods, and the outer surfaces of multiple second reinforcing rods near the bottom are fixedly installed with the outer surfaces of the other two side columns and the transverse column respectively.

[0011] Preferably, both ends of the plurality of horizontal columns are fixedly connected to a first connecting block, and the tops and bottoms of the plurality of vertical columns are fixedly connected to a second connecting block.

[0012] Preferably, fixing holes are provided on the outer surfaces of the first connecting blocks and the second connecting blocks.

[0013] Preferably, the inner surfaces of the upper connecting block and the lower connecting block are matched with the outer surfaces of the side columns.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the present invention, the upper connecting block, the lower connecting block, the hanging ring, the fixing piece, the lower connecting block and the fixing rod cooperate to conveniently fix the hanging ring on the side column, so as to facilitate the subsequent lifting needs. At the same time, under the action of the first reinforcing rod and the second reinforcing rod, the bearing capacity and force performance of the side column are increased, thereby improving the stability of the foundation section during lifting.

[0025] The effect achieved by the entire embodiment 1 is that during use, the vertical column 1, the horizontal column 2 and the side column 3 are all fixedly installed using universal mounting parts. With the cooperation of the first connecting block 4 and the second connecting block 8, the foundation can be extended vertically and horizontally, and then fixed by inserting bolts and nuts into the corresponding fixing holes 9 to complete the extension. At the same time, when the foundation section is raised or lowered, the lower connecting block 605 and the upper connecting block 601 are covered at the outer center position of the side column 3 and aligned so that the corresponding through holes are aligned, and then the fixing parts 604 (bolts and nuts) are used. The hanging ring 602 is fastened and installed to fix it on the side column 3. After it is installed on the two side columns 3 at the top of the base section, it can be connected to the hooks of the external lifting equipment through the hanging rings 602 on both sides, and can be lifted and lowered after being limited by the external limit assembly, making the base section more convenient to lift and lower.

[0027] The effect achieved by the entire embodiment 2 is that when the base section is lifted or lowered by the hanging ring 602 , the reinforcement ribs 603 on both sides increase the stability of the hanging ring 602 and reduce the risk of the hanging ring 602 falling off.

[0028] Working principle: With the cooperation of the first connecting block 4 and the second connecting block 8, the foundation can be extended vertically and horizontally, and then fixed by inserting bolts and nuts into the corresponding fixing holes 9 to complete the extension. At the same time, when the foundation section is lifted, the lower connecting block 605 and the upper connecting block 601 are covered at the outer center position of the side column 3 and aligned so that the corresponding through holes are aligned. Then, the fixing parts 604 (bolts and nuts) are used to tighten and install, thereby fixing the hanging ring 602 to the side column 3, and the two side columns at the top of the foundation section are fixed. After being installed on the column 3, it can be connected to the hook of the external lifting equipment through the hanging rings 602 on both sides. The reinforcing ribs 603 on both sides increase the stability of the hanging rings 602, and are limited by the external limit assembly before lifting, making the base section more convenient when lifting. Under the action of the second reinforcing rod 7, the stability of the side column 3 and the cross column 2 is increased. Under the action of the first reinforcing rod 5, a triangle is formed between the column 1 and the side column 3, thereby increasing the bearing capacity and force performance of the side column 3, and improving the stability of the base section when lifting.
