Description
Technical Field
The utility model relates to a architectural equipment field, concretely relates to horizontal truss negative and positive corner connecting piece.
Background
The attached lifting scaffold is called a lifting frame for short, is commonly called a climbing frame, and is external protection construction equipment used in high-rise and super high-rise building construction. The climbing frame operating platform is less in material usage, convenient to assemble and high in practicability; meanwhile, the construction site is neat, and civilized construction of the whole construction site is facilitated. An attached lifting scaffold comprises a working platform, a truss system, a supporting system, a lifting system and a protection system. The space truss system adopted by the existing attached lifting scaffold comprises scaffold boards, upright rods, horizontal trusses and triangular supports, wherein the scaffold boards, the upright rods, the horizontal trusses and the triangular supports are respectively connected with a scaffold body through bolts to form a complete force bearing and transferring system and a stable space structure system. The horizontal truss plays an important role in the horizontal truss, and the installation position of the horizontal truss is generally arranged at the bottom layer of the frame body (arranged along the circumference of the frame body). When the horizontal truss is connected into a unified whole through the bolts, the horizontal truss can disperse and transmit force, and avoids safety accidents caused by local instability of the frame body. Research shows that the attention degree of the large and various types of attached lifting scaffolds in the industry at present on the horizontal truss is not enough, and meanwhile, the connection of the male and female angular positions is difficult to process, and a good connection mode is not provided, so that the problem that most of the personnel in the industry can connect the bottom horizontal truss into a unified whole is not seen. Only when the horizontal truss is connected into a unified whole, the space structure of the whole frame body is the most stable, and the safety performance can reach the best state.
Currently, there are three general ways in the industry to integrate horizontal truss connections into a unified whole: the first is that all the horizontal trusses are not connected into a unified whole, but the horizontal trusses on the large surface are connected with each other through bolts, and the switching positions are not connected; the second is that the horizontal trusses on the large surface are connected with each other through bolts, and the corners are bound together by iron wires; and the third is that the horizontal trusses on the large surface are connected with each other through bolts, and the corners are connected in a welding mode.
The disadvantage of the first mode is that the horizontal trusses are not connected into a unified whole, a complete space structure system cannot be formed, the load on the frame body cannot be well dispersed and transmitted to the main structure of the building, potential safety hazards exist in the using process, and local instability is easily caused when the load on the frame body is large. The iron wire binding connection is too simple, torque cannot be transmitted, strength and rigidity cannot meet the force transmission, and equivalently, connection is not performed. When the frame body is connected in a welding mode, load can be transmitted, but welding quality is controlled, manual machines are consumed, working efficiency can be reduced, welding parts are prone to rusting, and the safety of the frame body is threatened. When the horizontal truss is frequently disassembled due to actual conditions on site, the welding connection mode is not suitable.
Therefore, a connecting member used with a horizontal truss in an attached type lifting scaffold space truss system is urgently needed.
