Connecting device and construction process for avoiding collision between line pipe and floor truss rib

Abstract

The invention belongs to the field of buildings, and relates to a connecting device and a construction process for avoiding collision between a line pipe and a floor truss rib. The firmness of connection can be effectively improved. A double-internal-thread expanded-opening circular pipe hoop connecting embedded part is formed by improving a double-internal-thread-opening circular pipe hoop, an external thread fastening bolt arranged on an electrical line pipe in a sleeving mode is rotated into a sleeve of the double-internal-thread expanded-opening circular pipe hoop connecting embedded part,and a wrench is used for fastening; in the screwing-in process, under the effect that the double-internal-thread expanded-opening circular pipe hoop connecting embedded part with the gradually-reduced hole diameter, a gap in the sleeve of the external-thread fastening bolt is compressed, and then the effect of fixing the electrical line pipe is achieved, so that the electric line pipe, the external thread fastening bolt and the double-internal-thread expanded-opening circular pipe hoop connecting embedded part are connected into a firm whole, the main body structure is simple, the design concept is ingenious, the application environment is friendly, and the market prospect is wide.

Description

Technical field: [0001] The invention belongs to the field of construction, and relates to a novel connection structure between wire pipes and laminated floor truss bars, in particular to a connection device and a construction process for avoiding collision between wire pipes and floor truss bars, which can effectively improve the firmness of the connection. Background technique: [0002] In recent years, prefabricated concrete structures have been widely used in the field of housing construction because they can effectively improve building quality and construction efficiency; save materials, save energy, reduce emissions and protect the environment, save labor and improve working conditions; shorten the construction period and facilitate winter construction, etc. Therefore, it plays a major role in my country's construction industrialization. [0003] At present, there are many problems in the on-site construction of prefabricated concrete laminated slab members, and one of...

Problems solved by technology

[0003] At present, there are many problems in the on-site construction of prefabricated concrete laminated slab members, and one of the more common problems is that the diameter of the on-site electrical wire pipe is too large to pass through the truss bars of the laminated slabs. The clear distance on the upper surface of the thick base plate is generally 35mm, and the outer diameter of some electrical wire pipes is greater than 35mm, so that the electrical wire pipe 7 cannot pass through the truss reinforcement of the laminated plate, and the on-site construction personnel often use the method of cutting the upper chord reinforcement of the truss reinforcement to solve the above problems , but this leads to the reduction of the shear strength of the laminated slab, burying hidden dangers for the structural safety of the building

[0004] In view of the current problem of collision between electrical wire pipes and truss bars in the actual construction process of prefabricated concrete composite slab components, this invention intends to combine the actual construction needs of prefabricated concrete composite slab components and electrical circuit layout, by using the prefabricated concrete floor During the production process, we sought to design a method to connect a new type of wire pipe joint to the upper chord steel bar of the truss bar, which will be used for the connection and layout of the electrical wire pipe in the later construction work, avoiding the collision between the electrical wire pipe and the truss bar, and solving the problem. Potential safety hazard of reduced shear strength of laminated slabs
