Description
Technical field
The invention belongs to prefabrication technical fields, and in particular to a kind of half grout sleeve connection of self-tightening type
Part.
Background technique
In the past few decades in the time, China's building trade flourishes, and is greatly promoted the growth of national economy.
Energy conservation and environmental protection is required to realize in face of China's increase of land transfers expense now, the continuous rising of the artificial price of labour, people
Step up, the international competition pressure that building trade is faced is increasing.To improve core competitiveness, new industry industry
Mode --- prefabrication comes into being.
Prefabricated concrete structure refers to the coagulation being assembled by precast concrete by reliable connection type
Soil structure, including assembled monolithic concrete structure, full assembly concrete structure etc..In construction projects, abbreviation assembled is built
It builds;In Structural Engineering, abbreviation fabricated construction.
Traditional house building technology production efficiency is low, speed of application is slow, the construction period is long, high material consumption and worker's labor
Fatigue resistance is big, a series of this situation has not adapted to rigid demand of the modern society to house.And assembled architecture is with following
Feature: 1. design diversification can be designed according to housing need；2. function modernizes, a variety of energy conservation and environmental protections can be used
Equal new materials；3. manufacturing works can make building components and fittings unify the factorial production, by once；4. construction assembly
Change, labour can be greatly reduced, reduces waste of material；5. time optimization accelerates construction period obviously.Therefore, it faces
It is imperative to optimize building industry mode as early as possible for the increasing housing need in China.
Assembled architecture focuses on the protection to environment, resource, and building sewage, You Haiqi are effectively reduced in work progress
Body, the discharge of dust and construction noise pollution, reduce various influences of the construction on surrounding enviroment, be conducive to improve build
The labor productivity built promotes the fining of design, building, promotes the total quality and energy-saving and emission-reduction water rate of building, promote
Building Trade in China sustainable health development meets the demand of national economic development.
Summary of the invention
In order to improve the overall performance of fabricated construction and convenient for its construction, the present invention utilizes the design using component connection
Method further increases its performance indexes, and a series of reinforcement processing is carried out to it, and it is high, whole to develop a kind of bearing capacity
Body is good, safe and reliable and installation is simple and the fabricated construction connector of low cost.
The present invention relates to a kind of half grout sleeve connectors of self-tightening type, are mainly used in Vertical bar connection, including cut
The connection of power wall, frame column, hanging plate lamp.The composition of half grout sleeve connector of self-tightening type includes grouting mouth, thick liquid discharge mouth, dials
Piece, screw thread, sleeve and reinforcing bar, the sleeve diameter are greater than the diameter of reinforcing bar, and sleeve lining is provided with screw thread, lower cartridge setting
There is grouting mouth, upper cartridge is provided with thick liquid discharge mouth, and is in the milk between mouth, thick liquid discharge mouth on sleeve lining and is provided with plectrum.
The plectrum divides upper layer and lower layer, and upper layer includes two plectrums and is located at left and right sides of sleeve lining, lower layer's packet
It includes two plectrums and is located at sleeve lining front and rear sides, be more uniformly stressed connector.
The plectrum is the class wedge structure that cross section is 1/4 circular ring shape, and the vertical cross-section top half of plectrum is upper bottom
Long bottom is so short that right-angled trapezium, and upper base angle is 45 °, and the vertical cross-section lower half portion of plectrum is also that the long bottom in upper bottom is so short that right angle ladder
Shape, lower base angle is 10 °, and the outer diameter of circular ring shape is consistent with sleeve diameter, and the upper plane of four plectrums forms a complete circle
Ring；Plectrum is by bottom and is fixed on sleeve.Reduce resistance when reinforcing bar insertion by the gradient below setting plectrum, dials
Plane above piece increases the resistance of structure.
Plectrum is strutted using structure self gravity in reinforcing bar insertion, last plectrum can be stuck on the screw thread of reinforcing bar, be increased
Structure bonding strength is added.
Plectrum and screw thread are increased in sleeve, improve the intensity that reinforcing bar is in connection, but also can shorten sleeve
Length reduces grouting quantity, thus save the cost.
It is of the invention compared with existing, beneficial effects of the present invention:
Present invention utilizes structure self gravitys to carry out structure connection, keeps structure stronger；Sleeve slightly increases directly
Diameter, which increases serious forgiveness；Attachment force is increased since plectrum exists, it can the length appropriate that connector be reduced；Sleeve
In increase plectrum and screw thread, improve the intensity that reinforcing bar is in connection, but also the length of sleeve can be shortened, reduce grouting
Amount, thus save the cost；Sleeve lining makes shape of threads, increases the frictional force of barrel, so as in the length for reducing connector
Guarantee bonding strength while spending.
