Description
Technical field
The present invention relates to construction industry attachment device technical field, in particular to material muscle company is answered in a kind of resistance to plucking fiber reinforcement
Female connector cylinder.
Background technique
In recent years, it scientific and technical development and constantly brings forth new ideas and has greatly pushed the fast development of construction industry, it is existing in construction
Field carry out house assembling revolutionizes the housing construction way that tradition falls behind.With the development of building industrialization, various countries' handle is built
Build component factory prefabricating and important symbol of the assembling as modernization of the housing industry of constructing.Along with assembled architecture industry
Development possesses lightweight, high-strength, corrosion resistant, the fiber reinforcement without many good characteristics such as magnetic answer material muscle and are obtained and widely apply.
And fiber reinforcement answers the fabricated development of material muscle and brings new problem and contradiction: the connection of each assembled plate block is asked
Topic.And the overall performance superiority of fabricated construction will directly be influenced by each assembled plate block connector performance, will dominate
The development potentiality and the market space that future architecture is built.Therefore, fiber reinforcement is answered material muscle connecting component and is particularly important.
It is shown according to lot of documents, Current Domestic Wai Ge road scholar proposes steelframe attachment device different theories
And imagination, but generally there are following problems:
(1) due to the otherness of construction technology, easily cause fiber reinforcement multiple by the rigid connection that material muscle is answered in fiber reinforcement
The weakness of material muscle junction, junction safety are unable to get guarantee.
(2) it is made to generate plastic deformation by way of extruder compression steel bushing, by plastic deformation after sleeve and fibre
Dimension enhance between multiple material muscle be mutually twisted fastening force realize two fiber reinforcements answer the mode of the connection of material muscle to sleeve and
Base material has an adverse effect, and is easy to form fatigue fracture in extrusion process.
(3) unidirectional threaded connection is also easy to produce cunning after be easy to causeing the improper operation of construction personnel that fiber reinforcement is made to answer material muscle stress
De- phenomenon, so that weakness occurs in junction.
(4) since mortar and fiber reinforcement answer material muscle into face contact, material muscle is answered in fiber reinforcement when by dynamic loading
The twisting action relative to sleeve easily occurs, destroys junction.
Based on the above issues, propose that material muscle connection sleeve is answered in a kind of resistance to plucking fiber reinforcement.
Summary of the invention
