[0026] like Figures 1 to 6As shown, the embodiment of the utility model provides a prefabricated balcony 100 installation and fixing device, which is used to connect the prefabricated balcony 100 to the prefabricated exterior wall 200. The prefabricated balcony 100 installation and fixing device includes a screw sleeve 1, a first connecting member 2 and an adjustable component 3. The screw sleeve 1 is pre-embedded in the prefabricated exterior wall 200 and the prefabricated balcony 100. The adjustable component 3 includes an adjusting member 31 and two second connecting members 32. The two ends of the adjusting member 31 are respectively threadedly connected to the two second connecting members 32, and the thread directions of the two second connecting members 32 are opposite. Specifically, the adjusting member 31 has a through hole, which penetrates the adjusting member 31 along the length direction of the adjusting member 31, and the second connecting member 32 extends into the through hole.

[0027] One end of the first connecting member 2 is threadedly connected to the screw sleeve 1, and the other end of the first connecting member 2 is hinged to the end of the second connecting member 32 away from the adjusting member 31, so that the prefabricated balcony 100 is connected to the prefabricated exterior wall 200 through the first connecting member 2 connected to the adjustable component 3 and the screw sleeve 1 respectively. Since the two ends of the adjusting member 31 are threadedly connected to the second connecting member 32 respectively, the second connecting member 32 is coaxially arranged with the adjusting member 31, and the thread directions of the two second connecting members 32 located on the opposite sides of the adjusting member 31 are opposite, so that the two second connecting members 32 can be moved toward or away from each other at the same time by rotating the adjusting member 31, which plays the role of tightening the first connecting member 2, so that the adjusting member 31 can be used to tighten and position the second connecting member 32 when the prefabricated balcony 100 is hoisted and positioned, and the prefabricated balcony 100 is not easy to deviate after positioning, which reduces the safety risk of on-site construction and avoids the horizontal deviation of the prefabricated balcony 100 caused by other construction processes before concrete pouring after the prefabricated balcony 100 is hoisted.

[0028] In the above embodiment, the first connecting member 2 includes an integrally connected screw 21 and a connecting portion 22, the screw 21 is threadedly connected to the screw sleeve 1, and since the screw sleeve 1 is pre-embedded in the prefabricated balcony 100 and the prefabricated exterior wall 200, the first connecting member 2 can be stably connected to the prefabricated balcony 100 and the prefabricated exterior wall 200. The connecting portion 22 and the second connecting member 32 are hingedly connected by a pin 4, so that the first connecting member 2 can be connected between the screw sleeve 1 and the second connecting member 32, and the connection angle between the first connecting member 2 and the second connecting member 32 can be appropriately adjusted according to the on-site conditions to adapt to prefabricated exterior walls 200 of different sizes. Specifically, the connecting portion 22 has a U-shaped groove 221, and one end of the second connecting member 32 extends into the U-shaped groove 221. The connecting portion 22 has a first through hole 222 passing through the U-shaped groove 221, and the end of the second connecting member 32 away from the adjusting member 31 has a second through hole 321, and the pin member 4 is detachably provided with the first through hole 222, the second through hole 321 and the U-shaped groove 221. Preferably, the pin member 4 includes a bolt 41 and a nut 42, one end of the screw passes through the first through hole 222, the second through hole 321 and the U-shaped groove 221, and the nut 42 is threadedly connected to the bolt 41 and abuts against the connecting portion 22, so that after the construction is completed, the adjustable component 3 and the first connecting member 2 can be detached and used in a turnover manner, thereby reducing the construction cost.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the screw sleeve 1 embedded in the prefabricated balcony 100 is located on the left and right ends of the prefabricated balcony 100, and is vertically embedded in the left and right ends of the prefabricated balcony 100; the screw sleeve 1 embedded in the prefabricated exterior wall 200 is located on the left and right sides of the prefabricated balcony 100, and is vertically embedded in the outer side of the prefabricated exterior wall 200. Specifically, the screw sleeve 1 includes an integrally formed inner thread sleeve 11, a baffle 12 and a convex portion 13, the baffle 12 and the screw portion are respectively connected to the two ends of the inner thread sleeve 11, the inner thread sleeve 11 is threadedly connected to the first connecting member 2, the baffle 12 of the screw sleeve 1 embedded in the prefabricated balcony 100 abuts against the end surface of the prefabricated balcony 100, the inner thread sleeve 11 and the convex portion 13 of the screw sleeve 1 embedded in the prefabricated balcony 100 extend into the interior of the prefabricated balcony 100, and the convex portion 13 has threads, To improve the stability of the prefabricated balcony 100, the baffle 12 of the screw sleeve 1 embedded in the prefabricated exterior wall 200 abuts against the outer surface of the prefabricated exterior wall 200, and the inner thread sleeve 11 and the protrusion 13 of the screw sleeve 1 embedded in the prefabricated exterior wall 200 extend into the interior of the prefabricated exterior wall 200. The protrusion 13 has a thread, which improves the stability of the prefabricated exterior wall 200, thereby effectively ensuring the connection stability of the screw sleeve 1 embedded in the prefabricated balcony 100 and the prefabricated exterior wall 200.

[0030] In the above embodiment, the adjusting member 31 is preferably a closed flower basket, and a friction pattern 311 is provided on the surface of the adjusting member 31 to increase the friction force when the adjusting member 31 is rotated by a tool, thereby facilitating the rotation of the adjusting member 31 .

[0031] The installation method of the above-mentioned prefabricated balcony 100 installation fixture is as follows:

[0032] (1) When the prefabricated balcony 100 and the prefabricated exterior wall 200 are produced in the factory, the screw sleeve 1 is embedded according to the detailed design drawings. The positioning deviation during embedding should meet the design requirements. When pouring the concrete of the prefabricated component, it should be ensured that the inner thread sleeve 11 on the screw sleeve 1 is not blocked.

[0033] (2) After the prefabricated exterior wall 200 and the prefabricated balcony 100 are hoisted, the first connecting members 2 are respectively installed in the pre-buried screw sleeves 1 and tightened.

[0034] (3) The two second connecting members 32 are connected and assembled into an adjustable component 3 through the adjusting member 31. The second connecting members 32 at both ends of the adjustable component 3 are respectively connected to the first connecting member 2 through the pin members 4, and then the second connecting members 32 are tightened by rotating the adjusting member 31.

[0035] In summary, the utility model embeds the screw sleeve 1 in the prefabricated exterior wall 200 and the prefabricated balcony 100 respectively, uses one end of the first connecting member 2 to be threadedly connected to the screw sleeve 1, uses one of the second connecting members 32 on the adjustable component 3 to be hinged with the first connecting member 2 connected to the prefabricated balcony 100, and uses another second connecting member 32 on the adjustable component 3 to be hinged with the first connecting member 2 connected to the prefabricated exterior wall 200. By rotating the adjusting member 31 on the adjustable component 3, the two second connecting members 32 can be driven to move closer to or away from each other at the same time to adjust the installation positioning of the prefabricated balcony 100, and it is not easy to deviate after fixing, thereby reducing the time for precise positioning of hoisting and ensuring the positioning quality of the prefabricated balcony 100 after concrete pouring.
