The utility model belongs to the technical field of buildings, and particularly relates to a prefabricated sandwich heat preservation wall connecting piece. The prefabricated sandwich heat preservation wall connecting piece comprises a casing pipe and connecting rods. Two internal threads with opposite screwing directions are arranged inside the casing pipe, each connecting rod is in an L shape, one end of the horizontal part of each connecting rod is provided with an external thread which is in threaded connection with the corresponding internal thread on the casing pipe, the other end of the horizontal part of each connecting rod is provided with a vertical part, the two connecting rods are respectively connected to the interior of the casing pipe in a screwing mode, and the vertical parts of the connecting rods are arranged outside the casing pipe. The prefabricated sandwich heat preservation wall connecting piece is connected fast and conveniently and is simple in structure, the installation is finished through a method that only two connecting pieces are respectively connected to the interior of the casing pipe in a screwing mode, the structure is simple, the L-shaped connecting pieces play a very good shearing resistance role, service life is long, the rough surface can increase the friction force, and the prefabricated sandwich heat preservation wall connecting piece is suitable for various sandwich heat preservation walls.
Description
Technical field:
The utility model belongs to technical field of buildings, refers in particular to a kind of prefabricated sandwich heat preserving wall body connector.
Background technology:
Building energy conservation is the important component part of China's energy conservation, and wherein body of wall energy-conservation is one of Main Means of realizing building energy conservation.Heat-preserving wall has obtained good development and popularization at building field.At present, in engineering, heat-preserving wall commonly used includes three kinds of inside heat insulation wall body, external heat insulating wall and sandwich heat preserving wall bodies.Inside heat insulation wall body exists heat bridge phenomenon, is unfavorable for interior decoration, and base insulating layer is prone to defects i.e.cracks; External heat insulating wall exists the problems such as fire prevention, durability and the negative blast of opposing; The sandwich heat preserving wall body heat insulating material is placed between inside and outside concrete panel, can effectively prevent extraneous factor to the destruction of heat insulating material, is that in three kinds of heat-insulation wall plates that adopt at present, effect is best.
The sandwich heat preservation wallboard needs to connect by connector concrete crucial structure of internal layer steel concrete, insulation layer and outer reinforcement of sandwich heat preservation wallboard in work progress, play the shearing action between each layer of opposing.
Summary of the invention:
The purpose of this utility model is to provide a kind of simple in structure, and is easy to connect, quick, the prefabricated sandwich heat preserving wall body connector that shearing resistance is effective.
The utility model is achieved in that
A kind of prefabricated sandwich heat preserving wall body connector, include sleeve pipe and connecting rod, be provided with two internal threads that rotation direction is opposite in described sleeve pipe, connecting rod is L-shaped, one end of the horizontal part of connecting rod be provided with sleeve pipe on the internal thread external screw thread, the other end that are spirally connected be provided with the vertical portion, be bolted with respectively two connecting rods in sleeve pipe, the vertical portion of connecting rod is arranged on outside sleeve pipe.
In above-mentioned sleeve pipe, two internal threads are symmetrical arranged from the middle part in sleeve pipe.
The external surface of above-mentioned sleeve pipe is matsurface.
Above-mentioned matsurface is screw thread or ridge design or several salient points or indentation or rib.
One end of above-mentioned sleeve pipe is provided with the convex annular edge of spacing use.
The external surface of the vertical portion of above-mentioned connecting rod is matsurface.
Above-mentioned matsurface is screw thread or ridge design or several salient points or indentation or rib.
The advantage that the utility model is given prominence to compared to existing technology is:
The utility model connects quick and convenient, simple in structure, only needs two connectors are screwed onto within sleeve pipe respectively to get final product, simple in structure, L shaped connector plays the effect of good shearing resistance, long service life, matsurface can increase frictional force, is applicable on various sandwich heat preserving wall bodies.

The specific embodiment:
The below is further described the utility model with specific embodiment, referring to Fig. 1-4:
A kind of prefabricated sandwich heat preserving wall body connector, include sleeve pipe 10 and connecting rod 20, be provided with two internal threads 31,32 that rotation direction is opposite in described sleeve pipe 10, connecting rod 20 is L-shaped, one end of the horizontal part 201 of connecting rod 20 be provided with sleeve pipe 10 on internal thread 31(32) external screw thread, the other end that are spirally connected be provided with vertical portion 202, be bolted with respectively two connecting rods 20 sleeve pipe 10 is interior, the vertical portion 202 of connecting rod 20 is arranged on outside sleeve pipe 10.
Interior two the internal thread 31(32 of above-mentioned sleeve pipe 10) middle parts in the sleeve pipe 10 are symmetrical arranged.Screw thread is long, is connected firmly.
The external surface of above-mentioned sleeve pipe 10 is matsurface, increases frictional force.
Above-mentioned matsurface is screw thread or ridge design or several salient points 40 or indentation or rib.
One end of above-mentioned sleeve pipe 10 is provided with the convex annular of spacing use along 101.
The external surface of the vertical portion 202 of above-mentioned connecting rod 20 is matsurface, the bond stress between increase and concrete.
Above-mentioned matsurface is screw thread or ridge design or several salient points 40 or indentation or rib.
Use of the present utility model:
Above-described embodiment is only one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
