[0043] It should be noted that chemical bolts are commonly used in the construction field and are prior art. The specific structure of chemical bolts will not be described in detail here.

[0046] Specifically, in one embodiment, the rotating rod 225 is a stud. The fixing member is two locking nuts, and the rotating part is locked between the two locking nuts by screwing the two locking nuts. In this way, the rotation position of the connecting ball 23 is fixed. Thus, the stability and reliability of the connection between the external frame inclined-stay device 200 and the external frame are ensured.

[0047] Of course, in alternative embodiments not shown in the drawings of the present application, the disk 222 can replace structures of other shapes such as an elliptical block or a square block.

[0048] Specifically, Figure 1 and Figure 2 As shown, in one embodiment, the rotating part includes a connecting ball 23 and a connecting sleeve 24. The connecting ball 23 has a connecting through hole 231; one end of the connecting sleeve 24 is arranged in the connecting through hole 231; the connecting ball 23 is also provided with a rotating through hole 232, the central axis of the rotating through hole 232 forms a certain angle with the central axis of the connecting through hole 231, and the rotating rod 225 is penetrated in the rotating through hole 232 and can rotate in the rotating through hole 232.

[0049] Specifically, in one embodiment, the connection ball 23 is locked between the two locking nuts by screwing the two locking nuts, thereby fixing the rotation position of the connection ball 23, thereby ensuring the stability and reliability of the connection between the external frame inclined-stay device 200 and the external frame.

[0050] Specifically, Figure 1 and Figure 2 As shown, in one embodiment, the connecting through hole 231 is a threaded hole, the connecting sleeve is a threaded sleeve, and the connecting sleeve is threadedly connected to the connecting through hole 231. That is, the connecting through hole 231 is a threaded hole, and the connecting sleeve 24 is provided with an external thread, and the external thread is threadedly connected to the internal thread of the connecting through hole. In this way, the connection length of the rotatable support 2 can be adjusted. Thereby, the flexibility of the connection between the external frame inclined-stayed device 200 and the external frame is further enhanced, and the range of the connection between the external frame inclined-stayed device 200 and the external frame is expanded.

[0051] Specifically, Figure 1 and Figure 2 as well as Figure 5 As shown, in one embodiment, an outer thread is provided on the outer circumference of the adjustable steel pipe 3, and an inner thread is provided on the inner hole wall of the connecting steel pipe 100, and the outer thread of the adjustable steel pipe 3 is threadedly connected with the inner thread of the connecting steel pipe 100. In this way, the connection length between the outer frame and the outer frame inclined-stayed device 200 can be adjusted. Thereby, the flexibility of the connection between the outer frame inclined-stayed device 200 and the outer frame is further enhanced, and the range of the connection between the outer frame inclined-stayed device 200 and the outer frame is expanded.

[0052] Specifically, Figure 3 As shown, in one embodiment, the embedded plate 1 includes a plate body and embedded steel bars. The embedded steel bars are arranged at the bottom of the plate body, and one end thereof away from the plate body is hook-shaped for fixing on the floor steel bars.

[0053] Specifically, Figure 3As shown, in one embodiment, the embedded plate 1 is provided with a plurality of long strip holes, and the bottom plate 21 is provided with a plurality of through holes, and the plurality of through holes are provided in one-to-one correspondence with the plurality of long strip holes. Connecting bolts are provided through the through holes and the corresponding long strip holes, and a connecting nut is provided at one end of the connecting bolt, and the bottom plate 21 is fixed to the embedded plate 1 by screwing the connecting nut. Among them, since the embedded plate 1 is provided with a plurality of long strip holes, the position of the bottom plate 21 is adjusted along the length direction of the long strip holes. Thus, the position of the rotatable support is adjusted. In this way, the connection position between the outer frame and the outer frame inclined-stayed device 200 can be adjusted. Thus, the flexibility of the connection between the outer frame inclined-stayed device 200 and the outer frame is further enhanced, and the range of the connection between the outer frame inclined-stayed device 200 and the outer frame is expanded.

[0054] In this embodiment, the embedded plate 1 is first fixed to the plate reinforcement by welding, mechanical connection, or binding before the concrete of the plate is poured. When pouring concrete, it is poured together with the plate reinforcement to form a whole. This method can ensure that the entire external frame system can be reliably connected to the main body, because the embedded plate is embedded in advance, it is not necessary to embed short pipes on the floor. When the external frame is dismantled later, it is not necessary to cut the embedded short pipes on the floor and repair the floor, which reduces the damage caused by secondary repairs and avoids the risk of leakage due to reserved holes.

[0055] In this embodiment, when the external frame is erected, a rotatable support 2 with a threaded sleeve is used to effectively connect with the embedded plate 1 through chemical bolts. The size (elongated hole size) and position of the bolt hole on the embedded plate 1 are determined according to the needs to avoid the position deviation of the embedded plate 1 during the later embedding, which makes it impossible to install. The bolt hole can also allow the rotatable support 2 to properly adjust the fixed position. When the threaded adjustable steel pipe 3 is fixed on the connecting sleeve 24, the rotatable support 2 realizes the direction of the sleeve rotation. The connection method of the rotatable support 2 with the threaded sleeve and the threaded adjustable steel pipe 3 can realize the adjustable length, which adapts to the uncertainty of the distance between the external frame system and the main body and the connection position with the external frame. At the same time, the rotatable support 2 with a threaded sleeve is connected by chemical bolts, which can be uniformly removed when the external frame is removed. After the embedded parts are removed, they only need to be processed by simple external wall plastering, secondary covering and other methods to proceed to the next process. The operation is simple and will not affect other processes. This connection device can also realize secondary turnover and adjustment.

[0056] In this embodiment, the installation length of the adjustable steel pipe 3 is adjusted, and the applicable length is fixed using the anti-slip clamp 4 to prevent the threaded steel pipe from sliding or falling off. Finally, the adjustable steel pipe 3 with the adjusted length is connected to the outer frame through the standard outer frame fastener, and the entire outer frame system is installed.

[0057] The external frame inclined-stayed device 200 of the utility model is easy to install and disassemble, the size can be adjusted, the engineering quality is improved, the leakage risk is reduced, and it can be reused. It can also be mass-produced through standardization to save cost and reduce production cost. At the same time, the attachment device can adapt to various working environments and is a safe and stable construction tool.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0059] The external frame inclined-stayed device 200 of the utility model has a simple structure. Compared with the traditional external frame erection process, it is unnecessary to pre-embed short pipes on the floor, which reduces the cutting and repair of short pipes on the floor in the later stage, and reduces the construction workload. In the later decoration stage, there will be no leakage problems due to the influence of the embedded steel pipe parts, and other processes in the main body can be intervened in advance to shorten the construction period. The rotating support in the device can be dismantled for turnover and reuse, which effectively saves costs. Thread adjustment can realize more application scenarios.
