Many deficiencies such as work speed is slow, work efficiency is low, construction quality is unstable.The building built with tradition wall material, its energy consumption are
Three times of developed country similar in weather or so.
In recent years, China progressively starts to use organic foam material between floors to keep the temperature the building heat preservation system of component
System, organic foam material is attached on retaining wall mostly in the system, and construction is complex, and fire protecting performance is poor, is unfavorable for
The sustainable development of construction industry.
And the building trade in China is to energy-saving, industrialization development, development and application structure-function integration at present
Prefabricated heat preservation wall body there is important economy and environmental benefit.
In conclusion developing, a kind of thermal conductivity factor is low, and corrosion resistance is good, and the convenient prefabricated thermal insulation FRP of installation connects
Fitting is the goal in research of those skilled in the art.
The content of the invention
It is an object of the present invention to provide a kind of new prefabricated heat preservation wall body bolt type connector, high-strength light, thermal conductivity factor be low,
Corrosion resistance is good, easy construction.
In order to realize the above object the technical solution adopted by the present invention is：A kind of new prefabricated heat preservation wall body bolt type connects
Fitting, including symmetrically arranged two blocks of steel plates, the both ends outward bending of the steel plate, opens up plate opening on the bending segment of steel plate,
Screw hole is opened up positioned at the centre position of steel plate, FRP bolts are connected with the screw hole, the nose threads of FRP bolts are connected with FRP
Nut；
The outside of two blocks of steel plates is located at the screw hole region and sets middle part anti-slip tank；
It is close to keep the temperature layer arrangement on the inside of two blocks of steel plates, is placed on outside two blocks of steel plates in concrete.
Further, steel plate washer is set between FRP bolts or FRP nuts on the outside of steel plate.
Preferably, the middle part anti-slip tank is the rectangular surfaces domain wide with steel plate.
It is further preferred that the wedge shaped shape in the free end of the bending segment of steel plate.
Further, the steel plate is substituted with FRP plate.
The technical effects of the invention are that：
(1) connector main body of the present invention connection use FRP material, reduces the scarce of connector existing good heat conductivity in itself
Point；
(2) integration of connector heat insulation function is realized；
(3) shear behavior is much larger than the connector of single FRP compositions；
(4) connector of the present invention under same model is applicable to the wall of different insulation layer thicknesses.

Embodiment
Referring to attached drawing, with reference to specific embodiment, the present invention is described in further detail, and described is to this hair
Bright explanation rather than restriction.
A kind of new prefabricated heat preservation wall body bolt type connector, including symmetrically arranged two blocks of steel plates 1, the steel plate 1
Both ends outward bending, opens up plate opening 3 on the bending segment of steel plate 1, screw hole, the screw hole is opened up positioned at the centre position of steel plate 1
On be connected with FRP bolts 2, the nose threads of FRP bolts 2 are connected with FRP nuts 5；
The outside of two blocks of steel plates 1 is located at the screw hole region and sets middle part anti-slip tank 6；
The inner side of two blocks of steel plates 1 is close to insulating layer 8 and is arranged, is placed on outside two blocks of steel plates 1 in concrete seven.
Connector of the present invention is made of two blocks of steel plates 1, FRP bolts 2, middle part anti-slip tank 6, FRP nuts 5.Steel plate 1 is by pouring
Shape is built up, and both ends bend up certain angle, and opening processing is carried out to bent portion and forms steel plate opening 4, the middle part of steel plate 1 carries out
Anti-skidding processing, adds concavo-convex portion, forms anti-slip tank 6 in the middle part of steel plate, its structure is as shown in the figure, two pieces of middle parts of steel plate 1 open up spiral shell
Hole, and be attached using FRP bolts 2, it is clamped using FRP nuts 5, connector is actual to be applicable in as shown in figure 5, embedded mixed
In solidifying soil 7 and insulating layer 8, wherein the distance between two blocks of steel plates 1 can be controlled by 2 length of FRP bolts, for adapting to various thickness
Insulating layer 8.
Benefit using the above structure is：Two blocks of upper and lower section of steel plates 1 are angled respectively, and carry out opening
Reason, increases its mechanical snap power between concrete seven.Steel plate 1 carries out coarse processing, i.e. steel plate 1 with 2 contact position of FRP bolts
Centre position open up the outside of screw hole and two blocks of steel plates 1 and be located at the screw hole region middle part anti-slip tank 6 is set, increase it
Frictional force.So obtain that structure light wt of the present invention is high-strength, thermal conductivity factor is low, corrosion resistance is good, easy construction.
Further, steel plate washer 3 is set between the outside of steel plate 1 and FRP bolts 2 or FRP nuts 5.The effect of steel plate washer 3
It is in order to avoid FRP bolts 2, FRP nuts 5 are directly contacted with steel plate 1.And then avoid causing the damage of FRP bolts 2, ensure this
The service life of inventive structure.
Preferably, the middle part anti-slip tank 6 is the rectangular surfaces domain wide with steel plate 1.So ensure FRP bolts 2 and
Locking after the installation of FRP nuts 5, and then ensure the stabilization of structure of the present invention.
It is further preferred that the wedge shaped shape in the free end of the bending segment of steel plate 1.Machine so between steel plate 1 and concrete seven
Tool snap-in force effect is more preferable.
Further embodiment, the steel plate 1 are substituted with FRP plate.The distance between such two pieces of FRP plates can pass through FRP
The length of bolt 2 is adjusted, its specific length is depending on wallboard thickness.
The present invention is by by FRP pultrusions, obtaining (and the FRP substituted of prefabricated heat preservation wall body FRP bolts 5 after cooling
Plate), both sides steel plate 1 (or FRP plate) is attached fixation using FRP bolts 5.Wherein connector both sides are located at concrete seven
In.The advantages of present invention realizes the structure-function integration of connector, low with thermal conductivity factor, anticorrosive, construction is simple.
Above content is the further description that mode is the present invention in conjunction with specific embodiments, it is impossible to assert the present invention
Embodiment be only limitted to this., can be with the frame of theory of the present invention for the technical field of the invention
Some simple differentiation are made, are regarded as belonging to the scope of patent protection that claims that the present invention is submitted determine.
