Building industrialization is the change of modern building mode of construction, is the mode of construction traditional by semi-hand semi-machine,
It is changed into the industrialized production of a kind of design standard, production industrialization, construction assembling and IT application in management, realization is built
Building industrialization can reduce labor intensity, and reduce cost, improve labor efficiency, and guarantee construction quality, it is most important that, Neng Goujie
About resource protects environment.
PC component (Prefabricated Concrete Component), i.e., " prefabricated dwelling house concrete component "
Abbreviation, also known as prefabricated components are the finished product concrete components being made with the batch production of component process unit, existing through constructing
Assembly, connection and part are cast-in-place and form concrete structure, are usually poured in the fixed forms such as punching block concrete curing
Made of component, have the advantages such as high-quality, efficient, energy-saving and environmental protection, be realize housing industrialization important channel.With China
The propulsion of housing industrialization, prefabrication are rising, and a large amount of engineerings use prefabricated construction, in prefabricated shearing
It needs when PC component is prefabricated in the factory, to need to connect using a large amount of full grout sleeve or half grout sleeve in wall and prefabricated post
Connector, and the connector and sleeve connection of half grouting in routine techniques are the threaded connections used, are met due to sleeve
The intensity of requirement, needs according to the corresponding wall thickness of Strength co-mputation, keeps the strong of wall thickness since wall thickness is particular wall thickness
Spend constant, using in screwing process, the screw thread on inner wall can destroy the corresponding intensity of wall thickness, therefore only for proof strength
The wall thickness that can increase sleeve eventually leads to sleeve wall thickness and increases again, to be formed, weight is big, the problem more than steel, and
And using the bad detection of screw-down torque in screwing process, it is possible to loosen in use process, increasing one may deposit
In the point of hidden danger, and at this, screw thread is generally all bigger, and processing is relatively difficult, costly.
Utility model content
The purpose of this utility model is to solve the mode that prior art middle sleeve and connector are directly threadably secured and making
At sleeve wall ratio it is thicker, consumption steel are relatively more, the problem of higher cost, provide a kind of half grout sleeve of PC component
Component.
The deficiency of the utility model to solve above-mentioned technical problem, used technical solution is:
A kind of half grout sleeve component of PC component including sleeve body and is fixed on connecing on sleeve body one end
Head, offers the through-hole being connected to sleeve body inner cavity at connector center, and the connector is wherein fixedly connected with outer diameter on one end
Less than the linkage section of the internal diameter of sleeve body, linkage section is inserted into sleeve body inner cavity, passes through transition between linkage section and connector
Section is connected as one, and changeover portion is that a center offers the round-like structure of through-hole, the bigger diameter end of round-like structure with
The outer diameter of connector connection and bigger diameter end is equal to connector outer diameter, and the miner diameter end of round-like structure is connect with linkage section and miner diameter end outer diameter
Equal to linkage section outer diameter, sleeve body is machined with the chamfering being mutually matched with round-like structure on one end of round-like structure
Structure, round-like structure and chamfering structure complement each other to form weld seam, and the layer being made of welding material, weldering are filled in weld seam
Seam is in the annular groove of isosceles triangle for section, and layer is the ring structure that section is in isosceles triangle, sleeve body and
Connector is fixed together by layer.
The linkage section, which protrudes on one end inside sleeve body, to be additionally provided with for guiding linkage section to be inserted into sleeve sheet
Intracorporal boot segment.
The outer diameter of the linkage section is 0-1mm smaller than sleeve body internal diameter.
The outer diameter of the linkage section is 0.2-0.5mm smaller than sleeve body internal diameter.
The beneficial effects of the utility model are: the utility model will be connect by the way that linkage section and changeover portion is arranged in connector top
Then head location and installation complements each other to form weldering by round-like structure and sleeve body chamfering structure inside sleeve body
Seam fills welding material in weld seam and the two is fixed together, while weld seam is set as isosceles triangular structure, and layer is also
Isosceles triangle is not only filled with weld seam, while ensure that the uniform force of layer two sides in weld seam, ensure that the secured of welding
Property, the problem of being changed in conventional threads connection procedure using the fixed form, need to increase sleeve body wall thickness, according to intensity
It keeps wall thickness inconvenient after calculating sleeve body wall thickness, to reduce the overall weight of sleeve, reduces making for steel
Dosage, to reduce costs.
Detailed description of the invention
