[0023] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.
[0024] Please refer to Figures 1 - 8 As shown, the purpose of this embodiment is to provide a vertical limit connector for the built-in insulation board of the cast-in-place concrete composite wall, including an inner wall 1. One end of the inner wall 1 is fixedly provided with a thermal insulation layer 2. One end of the thermal insulation layer 2 is fixedly provided with a protective layer 5. One end of the protective layer 5 is fixedly connected to a plastering layer 4. A steel mesh 3 is fixedly arranged in the protective layer 5. The thermal insulation layer 2 is used to improve the thermal insulation ability of the composite wall. The protective layer 5 is used to further prevent the thermal insulation layer 2 from falling off the inner wall 1 and at the same time improve the thermal insulation performance of the composite wall.
[0025] A limit sleeve 12 is fixedly installed in the thermal insulation layer 2. The middle of the inner wall 1 is fixedly connected with an L-shaped steel bar 10. One side of the L-shaped steel bar 10 is fixedly installed in the limit sleeve 12. The limit sleeve 12 is used to fix the L-shaped steel bar 10.
[0026] The limit sleeve 12 adopts a hollow hexagonal structure. The outer diameter of the L-shaped steel bar 10 is the same as the diameter of the inscribed circle of the hollow hexagon in the limit sleeve 12. The hollow hexagonal structure makes the L-shaped steel bar 10 not easy to shake in the limit sleeve 12.
[0027] One end of the limit sleeve 12 is fixedly connected to an outer clamping plate 8. The other end of the limit sleeve 12 is fixedly connected to an inner clamping plate 7. The outer clamping plate 8 is fixedly connected to one end of the thermal insulation layer 2. The inner clamping plate 7 is fixedly connected to the other end of the thermal insulation layer 2. A through hole is provided in the middle of the inner clamping plate 7, and the through hole corresponds to the position of the steel bar hole.
[0028] One end of the inner clamping plate 7 is fixedly connected to a disc 6. The inside of the disc 6 is hollow. The L-shaped steel bar 10 can pass through the disc 6. A cross groove is opened at the top of the disc 6 to form four mutually perpendicular clamping grooves. One end of the cross groove is opened inward to form an inwardly buckled clamping groove.
[0029] A cylindrical groove 61 is formed in the clamping groove of the disc 6. A spring 62 is fixedly installed in the cylindrical groove 61. The upper end of the spring 62 is fixedly installed with a limiting block 63, which can fix the L-shaped steel bar 10 at the clamping groove in the disc 6. A steel bar hole is provided in the disc 6. The L-shaped steel bar 10 is arranged inside the steel bar hole. The limiting block 63 is used to fix the L-shaped steel bar 10 in the clamping groove of the disc 6.
[0030] It should be noted that the side surface of the limiting block 63 is an inclined surface. When the end of the L-shaped steel bar 10 enters the U-shaped groove, it will first contact and squeeze the inclined surface of the limiting block 63, causing it to move downward and squeeze the spring 62. Therefore, the spring 62 will exert an upward elastic force on the limiting block 63, which in turn causes the limiting block 63 to squeeze the end of the L-shaped steel bar 10, thereby increasing the firmness of the end of the L-shaped steel bar 10 when it is clamped inside the U-shaped groove.
[0031] The other end of the L-shaped steel bar 10 is fixedly connected with an anti-corrosion cap 9, and the other end of the inner wall 1 is fixedly connected with an interior decorative layer 11. The anti-corrosion cap 9 is fixedly arranged at one end of the interior decorative layer 11.
[0032] When the present utility model is specifically used, the heat preservation capacity of the composite wall is improved through the heat preservation layer 2, and the heat preservation layer 2 is further prevented from falling off the inner wall 1 by setting the protective layer 5, while the heat preservation performance of the composite wall is improved. The steel bar mesh 3 is buckled on the disc 6. The disc 6 has two buckles at the reserved groove of the steel bar mesh 3, which can fix the steel bar mesh 3 and prevent it from coming out of the groove or moving, ensuring the precise combination of the heat preservation layer 2 and the steel bar mesh 3. The bent part of the L-shaped steel bar 10 is located in the steel bar hole of the disc 6, and the L-shaped steel bar 10 can be fixed at the disc 6. At the same time, a cross groove is opened at the top of the disc 6 to form four mutually perpendicular clamping grooves. A U-shaped groove is opened inward at one end of the cross groove to form an inward-clamping clamping groove. A cylindrical groove 61 is formed in the clamping groove of the disc 6. A spring 62 is fixedly installed in the cylindrical groove 61. The upper end of the spring 62 is fixedly installed with a limiting block 63. When the end of the L-shaped steel bar 10 enters the U-shaped groove, it will first contact and squeeze the inclined surface of the limiting block 63, causing it to move downward and squeeze the spring 62. Therefore, the spring 62 will exert an upward elastic force on the limiting block 63, which in turn causes the limiting block 63 to squeeze the end of the L-shaped steel bar 10, thereby increasing the firmness of the end of the L-shaped steel bar 10 when it is clamped inside the U-shaped groove, effectively avoiding the collision between the L-shaped steel bar 10 and the prefabricated steel bar cage of the building wall. The structure is tightly connected, with good load-bearing effect, and at the same time, it can also strengthen the connection between the heat preservation layer 2 and the inner wall 1, effectively avoiding the problem that the heat preservation layer may fall off due to poor bonding during use.
