Description

The pre-buried conduit of a kind of U type

Technical field

The utility model relates to the pre-buried conduit of a kind of U type, belongs to the fastening five metals technology of building field.Can be widely used in the installation of building curtain wall, railway, speedway, mining equiment, fastening engineering field.

Background technology

Built-in fitting is that (burying) member in concealed work is installed in advance, is the component and fitting of settling when structure is poured into a mould, and the overlap joint when being used to build superstructure by laying bricks or stones is beneficial to installing and fixing of external works Equipment Foundations.At building field traditional built-in fitting commonly used, be generally by connecting base and being fixed in the pre-buried bar that is connected on the base and forming.It connects base and mostly is cold rolling or hot rolling C type channel-section steel, and pre-buried bar mostly is screw-thread steel or i iron; Usually connect and adopt welding or riveted joint combination being connected of base and pre-buried bar.Because the welding position exists undercut, pore, rosin joint, thermal deformation and riveted joint position to exist undercut, cold deformation, stress defective such as to concentrate, and makes that the built-in fitting supporting capacity is poor, intensity is low.In addition, because the manufacturing process of traditional built-in fitting relies on more welding or staking process, the welding, the riveting tool anchor clamps that need are more, mostly be manual operations, be difficult to realize mechanization and automated production, so the quality uniformity of traditional built-in fitting is difficult for guaranteeing.

In recent years, with improving constantly of design level and building ability, curtain wall decoration, traffic track and highway construction field were had higher requirement to built-in fitting.The scientific research personnel and the engineers in building and material field have been carried out a large amount of work at the design and the manufacture view of built-in fitting.A kind of building C type channel-section steel embedded parts is provided in the Chinese patent (patent No.: ZL 200920010543.6), it is made of C type channel-section steel Connection Block and the pre-buried bar riveted joint of I shaped steel of being fixed on the Connection Block, do not adopt built-in fitting welding procedure commonly used, avoided defectives such as welding mechanics unstable properties, bearing load ability.But this built-in fitting is because the employing riveted joint connects technology, and the contact surface size and dimension that Connection Block bottom and pre-buried bar are riveted has higher requirement, and manufacturing procedure is still comparatively complicated.(notice of authorization number: provide a kind of building with C type groove built-in fitting 2265412Y), its technology is reasonable, simple in structure, be connected with outer connection member by T type bolt, but its pre-buried floor and riveting muscle has adopted welding procedure for Chinese patent.(notice of authorization number: a kind of building built-in fitting is provided CN2871676Y), and it has avoided the unmanageable problem of traditional built-in fitting welding quality to Chinese patent, and it is made up of Connection Block and fixture two parts, between the two by the riveted joint combination.As seen, traditional slot type built-in fitting for building is many to serve as to connect base with C type channel-section steel, connect pre-buried bar by welding or riveted way, so the processing and manufacturing process of traditional slot type built-in fitting must rely on welding or staking process, and mostly be manual operations, be difficult to realize mechanization and automated production, cause the quality uniformity of traditional built-in fitting to be difficult for guaranteeing.For this reason, study a kind of do not need welding or riveted joint connection, fully by punching press, roll forming, easily realize mechanization, automatic batch production, supporting capacity is strong, high life, slot type built-in fitting easy for installation is the technical task that this domain engineer and technician face.

Summary of the invention

The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of U type pre-buried conduit, and this U type conduit structurally is made up of U type Connection Block and the strong muscle of L type.Its processing and manufacturing process does not need welding or riveted joint, easily realizes mechanization or automated production, the intensity height.

The scheme that its technical problem that solves the utility model adopts is: the pre-buried conduit of U type is made up of U type Connection Block (1) and the strong muscle of L type (2), the strong muscle of L type (2) has one to interconnect the limit with the bottom (14) of U type Connection Block, and fillet is connected as a single entity both.

The cross section of U Connection Block (1) is irregular U shaped steel, the bottom of U Connection Block (14) is horizontal, bend in the both sides U type waists (11) of U Connection Block certain radian is arranged, the U opening part of U Connection Block is kinking structure under the level, the U open top end (13) of U Connection Block is parallel with surface, the bottom (14) of U Connection Block, and the down curved side (12) of the U opening of U Connection Block is vertical with the surface, bottom (14) of U Connection Block.

Several strong muscle of outward extending L type (2) are arranged on the bottom of U Connection Block (14), and the strong muscle of L type (2) is three limits formations under bottom (14) punching press of U type Connection Block directly, and the strong muscle of L type (2) has one to interconnect the limit with U type Connection Block bottom (14).

The utility model characteristics are: the strong muscle of L type of U type conduit bottom and the interior turn of bilge position of U type conduit both sides are fixed in the building substrate (as concrete), play the effect that connects building substrate (concrete); U conduit openend connects by movable adaptor.

Each structure position of the utility model does not need to be welded to connect, and fully by punching press, roll forming, can fundamentally solve problems such as mechanics instability, the supporting capacity of welding fabrication be limited, and realize mechanizationization, automatic batch production easily.
