Description

An external scaffolding wall-connecting device and construction method

technical field

The invention belongs to the technical field of building structure and construction, and in particular relates to an external scaffolding wall connecting device and a construction method. It is suitable for the installation and removal of steel pipe scaffolding used in the construction of cast-in-place slab masonry exterior walls, and also for the construction of cast-in-place reinforced concrete shear wall structures or other structures surrounded by reinforced concrete walls or columns and beams.

Background technique

External scaffolding is a necessary safety construction technical measure in building construction, and the use of connecting wall parts to connect walls is an important component necessary to ensure the stability and safety of its own structure. The collapse of scaffolding is usually caused by insufficient installation of connecting wall parts or failure to repair the connecting wall parts in time after being removed. The overall instability is the main failure form of scaffold instability. The damage begins with no connecting wall parts, poor lateral stiffness or initial failure. Bend larger lateral frames. The "Safety Technical Regulations for Fastener Type Steel Pipe Scaffolding in Building Construction" JGJ130-2011 requires that the vertical spacing of the wall parts should not be greater than the height of the building, and should not be greater than 4m. For structures with a height greater than 4m, only on each floor It is not enough to set up one connecting wall piece; for frame structures with large column spacing, set up connecting wall pieces in the way of holding columns. Horizontal setting, the force is unreasonable and there is no specific specification requirement for its method; therefore, setting up "connecting wall parts" with reasonable force, high bearing capacity, and conforming structure will improve the calculation span and lateral stiffness in the calculation unit. It plays a direct role and plays an important role in the overall stability of the scaffold.

At present, the common methods of connecting wall parts for fastener-type steel pipe scaffolding in China include: tension-brace combination method, embedded steel pipe method, steel column method, hoop column method, embedded steel plate method, etc. The tie-brace combination method has the advantages of low cost and no post-masonry filling process, but it is easy to be completely dismantled when the exterior wall is painted, resulting in potential safety hazards; the pre-embedded steel pipe method has the advantages of good rigidity and accurate embedding position, but the cost is high. It is troublesome to disassemble, and the hole left behind the masonry must be sealed later, which has hidden dangers of water seepage; the steel column method has the advantages of no hole filling process and no hidden danger of water seepage, but it is heavy and inconvenient for construction, especially for non-standard layer construction. Component standardization; hoop column method has the advantages of good rigidity, flexible and convenient construction, but construction requires more materials, and is not suitable for structures with large frame column spacing; pre-embedded steel plate method has good rigidity, no masonry hole filling process, no It has the advantages of hidden danger of water seepage, but there are disadvantages such as high cost, inconvenient construction, and hidden fire hazard.

It can be seen that there are many defects in the commonly used methods of connecting wall parts and there is no specific standardized product. This is also one of the problems in the scaffolding industry. When the construction layer cannot be installed with wall fittings, and when the coverage area of each wall fitting exceeds the specification requirements in a frame structure with a large column spacing, "connecting wall fittings" must be installed.

In view of this, there is an urgent need to invent a wall connecting member structure and construction method with good rigidity, large bearing capacity, low cost, convenient disassembly, and simple construction operation. The wall parts used in the present invention are embedded parts reserved in the cast-in-place floor slab, and the installation of the oblique rod and the vertical connector is installed on the floor, which is easy to operate and flexible to install; the horizontal connecting rod and the vertical connecting rod and The outer frame poles are all connected by fasteners, which is less difficult to construct, can be used repeatedly, can be recycled, and has good economic benefits.
