[0042] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0043] In an embodiment of this application, as Figures 1 to 7As shown in the figure, a prefabricated bay window structure includes a composite wall 10, a first embedded part 20, a connecting piece 30, and at least one cantilever slab 40. The composite wall 10 has a bay window opening 11. The first embedded part 20 is embedded in the composite wall 10 and is located at the upper sidewall and / or lower sidewall of the bay window opening 11. The cantilever slab 40 is installed at the bay window opening 11. A clamping groove 401 is provided on one side of the cantilever slab 40 close to the first embedded part 20. The clamping groove 401 penetrates one end face of the cantilever slab 40. An opening 4011 is provided on the side of the clamping groove 401 close to the first embedded part 20. The width of the opening 4011 is smaller than the width of the clamping groove 401. One end of the connecting piece 30 is connected to the clamping groove 401, and the other end passes through the opening 4011 of the clamping groove 401 and is connected to the first embedded part 20 to fix the cantilever slab 40 to the composite wall 10.

[0044] The composite wall 10 and the cantilever slab 40 are prefabricated components respectively. The cantilever slab 40 is a precast reinforced concrete slab. It should be noted that the connection method in the prefabricated bay window structure of the present invention is also applicable to the cantilever slab 40 of other structures. A bay window opening 11 is provided on the composite wall 10. The first embedded part 20 is embedded in the composite wall 10 on the upper side and / or lower side of the bay window opening 11. The cantilever slab 40 is installed at the bay window opening 11. The clamping groove 401 on the cantilever slab 40 corresponds to the first embedded part 20. One end of the connecting piece 30 is connected to the first embedded part 20, and the other end is clamped into the clamping groove 401 of the cantilever slab 40 to fixedly connect the cantilever slab 40 to the composite wall 10.

[0045] During installation, one end of the connecting piece 30 is connected to the first embedded part 20, and the other end of the connecting piece 30 extends out of the composite wall 10. Then, the cantilever slab 40 is inserted into the bay window opening 11 of the composite wall 10, so that the other end of the connecting piece 30 is clamped into the clamping groove 401 of the cantilever slab 40. Then, concrete is poured into the composite wall 10 to complete the assembly.

[0046] The number of the cantilever slabs 40 can be one or more. Exemplarily, when the number of the cantilever slabs 40 is one, the cantilever slab 40 can be arranged on the upper side or the lower side of the bay window opening 11. When the number of the cantilever slabs 40 is two, one cantilever slab 40 can be arranged on the upper side of the bay window opening 11, and the other cantilever slab 40 can be arranged on the lower side of the bay window opening 11. Whether the cantilever slab 40 is arranged on the upper side or the lower side of the bay window opening 11, its connection method with the composite wall 10 is the same, that is, both are fixed to the composite wall 10 by connecting the connecting piece 30 with the first embedded part 20 and the clamping groove 401.

[0047] In some embodiments, the clamping groove 401 extends along the first direction of the cantilever slab 40. The width of the opening 4011 along the second direction of the cantilever slab 40 is smaller than the width of the clamping groove 401. The first direction of the cantilever slab 40 is parallel to the thickness direction of the composite wall 10, and the second direction of the cantilever slab 40 is perpendicular to the first direction of the cantilever slab 40.

[0048] The cantilever slab 40 is inserted into the bay window opening 11. The first direction of the cantilever slab 40 is the width direction of the cantilever slab 40, and the second direction of the cantilever slab 40 is the length direction of the cantilever slab 40. The width direction of the cantilever slab 40 is parallel to the thickness direction of the composite wall 10. The card slots 401 and the openings 4011 on the card slots 401 extend along the width direction of the cantilever slab 40 respectively. The width of the opening 4011 along the length direction of the cantilever slab 40 is smaller than the width of the card slot 401 along the length direction of the cantilever slab 40.

[0049] During installation, one end of the connecting piece 30 is connected to the first embedded part 20, then the cantilever slab 40 is inserted into the bay window opening 11, and the other end of the connecting piece 30 is inserted into the card slot 401 from one end of the card slot 401. Since the width of the opening 4011 of the card slot 401 is smaller than the width of the card slot 401, the other end of the connecting piece 30 can be clamped in the card slot 401. Finally, the end face of the card slot 401 is blocked to fix the connecting piece 30 in the card slot 401, and the installation is convenient and fast.

[0050] In some embodiments, as Figure 8 shown, the first embedded part 20 is an embedded sleeve. As Figure 9 shown, the connecting piece 30 is a bolt. The embedded sleeve is provided with internal threads. The connecting piece 30 includes a head 31 and a rod portion 32 connected to the head 31. The size of the head 31 is larger than the size of the rod portion 32. The head 31 is connected to the card slot 401, and the rod portion 32 passes through the opening 4011 of the card slot 401 and is threadedly connected to the embedded sleeve.

[0051] Internal threads are provided in the embedded sleeve, external threads are provided on the rod portion 32 of the bolt. The head 31 of the bolt slides into the card slot 401 from one end of the card slot 401, and the rod portion 32 of the bolt passes through the opening 4011 of the card slot 401 and is threadedly connected to the embedded sleeve to realize the fixed connection between the cantilever slab 40 and the composite wall 10. The embedded sleeve and the bolt are both made of steel materials to improve the strength of the embedded sleeve and the bolt, and further improve the connection strength between the cantilever slab 40 and the composite wall 10.

[0052] The bolt can be a T-shaped bolt. The cross-section of the head 31 of the bolt is rectangular, and the cross-section of the card slot 401 is also rectangular. The shape of the card slot 401 is adapted to the shape of the head 31 of the bolt. The head 31 at the lower end of the bolt can slide into the card slot 401 and be clamped with the card slot 401. The length of the head 31 along the length direction of the cantilever slab 40 is greater than the length of the rod part 32 along the length direction of the cantilever slab 40 and greater than the length of the opening 4011 along the length direction of the cantilever slab 40. The length of the rod part 32 along the length direction of the cantilever slab 40 is less than the length of the opening 4011 along the length direction of the cantilever slab 40, so that the rod part 32 can pass through the opening 4011, and the head 31 cannot escape from the opening 4011. Further, the gap at the connection between the head 31 of the bolt and the card slot 401 is also filled with a plugging member to fix the head 31 of the bolt in the card slot 401 and prevent the bolt from moving in the card slot 401. The plugging member can be concrete or the like.

[0053] In some embodiments, as Figure 10 shown, it further includes a second embedded part 50. The second embedded part 50 is embedded in the cantilever slab 40, and the card slot 401 is provided on the second embedded part 50. By setting the card slot 401 on the second embedded part 50, the card slot 401 can be formed on the cantilever slab 40 after the second embedded part 50 is embedded in the cantilever slab 40. The second embedded part 50 is made of steel material to improve the strength of the second embedded part 50. It can be understood that the card slot 401 on the cantilever slab 40 can be directly formed on the cantilever slab 40 during the prefabrication of the cantilever slab 40, or can be obtained by post-processing, or can be obtained by embedding the second embedded part 50. The specific method of forming the card slot 401 on the cantilever slab 40 should not constitute a limitation to this application.

[0054] Preferably, as Figure 10 shown, a plurality of first anchoring parts 51 are respectively provided on two opposite outer side walls of the second embedded part 50, and the plurality of first anchoring parts 51 are anchored in the cantilever slab 40. By providing the first anchoring parts 51 on the second embedded part 50, the connection strength between the second embedded part 50 and the cantilever slab 40 can be improved. The diameter of the end of the first anchoring part 51 far from the second embedded part 50 is greater than the diameter of the end of the first anchoring part 51 connected to the second embedded part 50 to further improve the connection strength between the second embedded part 50 and the cantilever slab 40.

[0055] In some embodiments, at least one set of anchoring components is provided on the outer side wall of the first embedded part 20. As Figure 8 shown, the anchoring component includes two second anchoring parts 21, and the two second anchoring parts 21 are anchored in the composite wall 10. By providing the anchoring components on the first embedded part 20 and anchoring the anchoring components in the composite wall 10, the connection strength between the first embedded part 20 and the composite wall 10 can be improved.

[0056] The two second anchoring parts 21 are symmetrically arranged with respect to the center axis of the first embedded part 20. A through hole for passing through steel bars is provided inside the second anchoring part 21. The steel bars in the composite wall 10 can pass through the through hole in the second anchoring part 21 to reinforce the second anchoring part 21 and the composite wall 10. In addition, a through hole for the steel bars in the composite wall 10 to pass through is provided on the first embedded part 20, which can facilitate the positioning of the first embedded part 20 in the composite wall 10, make the positioning of the first embedded part 20 accurate when it is embedded in the composite wall 10, and can withstand a large tensile force. Cooperating with the connecting piece 30 and the clamping groove 401, the cantilever slab 40 can be conveniently and reliably fixed to the bay window opening 11 of the composite wall 10 at the construction site, forming an assembled bay window structure.

[0057] The present invention also provides an embodiment of an assembled exterior wall, including the assembled bay window structure described in any of the above embodiments. The assembled bay window structure is as Figures 1 to 10 shown. A bay window opening 11 is provided on the composite wall 10. Embedded sleeves (the first embedded parts 20) are embedded at the upper and lower sides of the bay window opening 11 of the composite wall 10 and are evenly distributed; the second embedded parts 50 are embedded in the upper and lower cantilever slabs 40 of the lightweight precast bay window structure, are evenly distributed and are arranged in one-to-one correspondence with the first embedded parts 20; after the above preparations are completed, first install the composite wall 10, and screw the T-shaped bolts (connecting pieces 30) into the embedded sleeves (the first embedded parts 20) through the external threads and the internal threads; then align the upper and lower cantilever slabs 40 of the lightweight precast bay window and push them into the bay window opening 11, so that the T-shaped bolts (connecting pieces 30) slide into the clamping grooves 401 of the cantilever slabs 40 to complete the installation of the bay window. Then, seal the gap between the clamping groove 401 and the T-shaped bolt (connecting piece 30), and carry out the cavity pouring of the composite wall 10.

[0058] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
