Description
Technical Field
The utility model belongs to the technical field of the tuber pipe installation, concretely relates to vertical tuber pipe connection structure.
Background
Ductwork is a system of ducts for air transport and distribution. There are two kinds of composite air pipe and inorganic air pipe. Composite air ducts are represented by the Durkduct air duct. They can be classified according to their sectional shapes and materials. The stainless steel air duct is made by coating sealing glue (such as neutral glass cement) on the seams such as seaming seam, rivet seam, flange flanging four corners, etc. Before the sealant is coated, dust and oil stains on the surface are removed. According to the cross section shape, the air pipe can be divided into a circular air pipe, a rectangular air pipe, an oblate air pipe and the like, wherein the circular air pipe has the smallest resistance but the largest height and size, and is complex to manufacture. So the application is mainly based on a rectangular air pipe. The air pipe can be divided into a metal air pipe, a composite air pipe and a polymer air pipe according to the material.
In present tuber pipe connection installation construction, the installation of general vertical tuber pipe all adopts the normal mounting method, carries out tuber pipe hoist and mount in the tube well promptly, specifically is: fix first tuber pipe on the tuber pipe vertical braces of installing in advance, hoist and mount next tuber pipe in proper order again to carry out outer flange joint with the tuber pipe of fixing well before, constructor adopts ordinary bolted connection with every tie point on the outer flange outside the tuber pipe, treat to connect well and inspect qualified back, according to the tuber pipe in the construction order from bottom to top in the tube well. However, when the secondary structure of the large air duct is constructed, the constructional column cannot be supported due to the existence of the air duct. If the secondary structure construction is carried out earlier, the vertical air pipe is installed after the secondary structure construction, so the space between the air pipe and the secondary structure is not enough, the air pipe cannot be connected, the construction difficulty is increased, the construction error is large, and the construction precision is influenced.
The invention content is as follows:
the utility model provides a vertical tuber pipe connection structure, the effectual problem of leading to the unable connection installation of tuber pipe because of secondary structure's construction of having solved among the prior art.
The utility model discloses a realize through following technical scheme:
