Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0029] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be broadly understood, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between the two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] Please refer to Figure 1 and Figure 2 , the assembled outer frame connecting wall piece comprises: an internal connecting component 100 embedded in the main body structure and an external connecting component 200 arranged outside the main body structure and assembled with the internal connecting component 100; wherein the internal connecting component 100 comprises: a steel bar embedded head 6, a embedded steel bar 8 and a steel bar head protection sleeve 9, the steel bar embedded head 6 is connected with the steel bar 1 inside the main body structure, the first end of the embedded steel bar 8 is fixedly connected (specifically welded) with the steel bar embedded head 6, the second end of the embedded steel bar 8 is sleeved with the steel bar head protection sleeve 9 and extends to the edge of the main body structure 2; the external connecting component 200 comprises: a steel bar threaded sleeve 13, a connecting steel bar 14, a steel pipe 15, a T-shaped anchor 16 and a rotating fastener 5, one end of the steel bar threaded sleeve 13 is detachably sleeved on the outside of the second end of the embedded steel bar 8, the other end is sleeved on the outside of the first end of the connecting steel bar 14, the second end of the connecting steel bar 14 is fixedly connected with the T-shaped anchor 16; the steel pipe 15 is sleeved outside the connecting steel bar 14 between the steel bar threaded sleeve 13 and the T-shaped anchor 16; the rotating fastener 5 connects the steel pipe 15 with the outer frame vertical rod 4.

[0031] In the construction process using the assembled outer frame wall connecting piece, the stress process is as follows: the outer frame anti-overturning force is transmitted to the T-shaped anchor 16 through the embedded steel bar 8 and the connecting steel bar 14 indirectly connected by the steel threaded sleeve 13, and acts on the longitudinal stiffness of the steel pipe 15, and is linked to the rotating fastener 5 and the outer frame stand 4.

[0032] After the outer frame is removed, the assembled outer frame wall connecting piece does not need to be cut during construction, and only the steel threaded sleeve connected with the embedded steel bar 8 needs to be removed, thereby saving materials and ensuring the overall visual quality of the main structure. In addition, since the internal connecting assembly and the main structure need to be blocked in a small area (compared with the hollow embedded steel pipe, the steel pipe hole is larger, and the embedded steel bar 8 of the utility model is solid, after the steel threaded sleeve is removed, only a small area outside the second end of the embedded steel bar 8 needs to be blocked), the influence on the overall structure is small, the strength is guaranteed, and the risk of water leakage is effectively reduced.

[0033] For the later hole filling construction process is as follows:

[0034] At present, the conventional hole filling method of the steel pipe connecting piece in the prior art is: anti-permeation fine stone concrete plugging and surface waterproof coating treatment; the anti-permeation fine stone concrete has lower strength than the original structural reinforced concrete because it first contacts the inner wall of the steel pipe, and even if the anti-permeation fine stone concrete is improved by one level, the strength of the construction area at this position is still low.

[0035] The assembled outer frame wall connecting piece of the utility model only needs to use a small amount of waterproof mortar and waterproof coating on the surface of the second end of the embedded steel bar 8 extending to the edge of the main structure (which can be referred to as the surface treatment method of the basement outer wall water stop bolt hole), and the influence on the overall wall surface structure is small because the device structure has a small surface treatment area. The later construction wall painting layer can be used, and the strength is guaranteed.

[0036] In addition, the embedded steel bar 8 can be made of waste materials from a steel bar processing plant, and the waste products can be recycled to reduce construction costs; the external connecting assembly can be recycled for construction, and is not easy to cause material loss. The internal connecting assembly can be manufactured in advance, has a simple structure, is easy to install, and meets the use of various construction areas. The waterproof plugging mortar can be used for plugging in the later period, the engineering quantity is small, leakage is not easy to occur, and the structural strength is guaranteed.

[0037] Specifically, the end face of the second end of the embedded steel bar 8 is provided with threads 10 matched with the steel bar threaded sleeve 13 and is wrapped by the steel bar head protection sleeve 9; the end face of the first end of the connecting steel bar 14 is provided with threads matched with the steel bar threaded sleeve 13. Based on the arrangement of the steel bar head protection sleeve 9, the threads on the end face of the second end of the embedded steel bar 8 can be protected from being contaminated by concrete when the main structure formwork 3 is installed, so that the internal connecting component and the external connecting component are connected (assembled and installed integrally) based on the threads 10 on the end face of the second end of the embedded steel bar 8 and the threads on the end face of the first end of the connecting steel bar 14. After the concrete pouring construction is completed, the formwork 3 and the steel bar head protection sleeve 9 need to be removed, and the reserved connecting area 11 of the steel bar sleeve 13 which has been connected with the second end of the embedded steel bar 8 is connected with the first end of the connecting steel bar 14 (as shown in the figure). Figure 1 The connected area 12 of the steel bar sleeve 13 is the area where the steel bar sleeve 13 is sleeved on the first end of the connecting steel bar 14, and the reserved connecting area 11 of the steel bar sleeve 13 is reserved for the area of the second end of the embedded steel bar 8. The outer side of the connecting steel bar 14 is pre-sleeved with a steel pipe 15, which is later pulled and connected with the outer frame stand column 4 through the rotating fastener 5, and the installation construction of the assembled outer frame wall connecting piece is completed. The steel bar threaded sleeve 13

[0038] Preferably, the steel bar threaded sleeve 13 is a first-grade steel bar galvanized straight threaded sleeve. The strength of the first-grade steel bar galvanized straight threaded sleeve is equivalent to the pulling strength of the large-diameter steel bar, and the node formed by the tightening and closing strength of the internal threads can be arranged at any position of the steel bar engineering lengthening connecting node in the conventional reinforced concrete member within the allowable strength in the specification design, which is equivalent to that the whole large-diameter steel bar penetrates the main body, so that the connecting strength between the internal connecting component and the rest parts of the external connecting component is guaranteed, so as to guarantee the overall strength of the assembled outer frame wall connecting piece and improve the construction safety.

[0039] Further, the diameters of the embedded steel bar 8 and the connecting steel bar 14 are smaller than the inner diameter of the steel pipe 15, the outer diameter of the steel bar threaded sleeve 13 needs to be designed considering the diameters of the embedded steel bar 8 and the connecting steel bar 14, and the inner diameter of the steel pipe 15 is smaller than the outer diameter of the steel bar threaded sleeve 13. The steel pipe 15 protects the connecting steel bar 14 inside and is connected with the outer frame through the rotating fastener 5, so as to guarantee the overall action of the assembled outer frame wall connecting piece. In the embodiment, the wall thickness of the steel pipe 15 is preferably 3 mm, the inner diameter of the steel pipe 15 is 48 mm, and the outer diameter of the steel bar threaded sleeve 13 is 42 mm.

[0040] In the embodiment, the steel bar embedded head 6 is a T-shaped steel bar embedded head or a U-shaped steel bar. The steel bar embedded head 6 is reserved in the main structure (the main structure is a wall, a column, a beam or a plate), and is pulled and connected with the steel bar 1 inside the main structure through welding or anchoring, so as to ensure the anchoring stability of the internal connecting component.

[0041] Preferably, the T-shaped anchor 16 is a T-shaped steel bar, and the second end of the connecting steel bar 14 is welded with the T-shaped steel bar as a horizontal bar anchor to ensure the stability of the anchor of the connecting steel bar 14.

[0042] In addition, the T-shaped anchor can also be designed to include a steel plate and a screw sleeve fixed vertically with the steel plate, and the screw sleeve is sleeved outside the other end of the connecting steel bar 14.

[0043] It can be understood that the above examples are only examples for better understanding the technical solutions of the embodiments of the present application, and are not the only limitation of the embodiments.

[0044] Secondly, those skilled in the art should also know that the embodiments described in the specification all belong to preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0045] In summary, the assembled outer frame wall connecting piece provided by the present application has the following advantages:

[0046] 1) Compared with the steel pipe connecting piece of the prior art, after the outer frame is dismantled, the pre-buried steel pipe of the connecting piece left on the site needs to be cut off, and there is a loss of pre-buried steel pipe and rotating fasteners; while the assembled outer frame wall connecting piece of the present application only has a loss of internal connecting components, and the external connecting components can be recycled and used, and the internal connecting components can be processed by using the waste steel bar heads of the processing plant, which utilizes waste materials and reduces material loss and construction cost.

[0047] 2) After the outer frame is dismantled, there is no need for cutting construction, and only the steel bar threaded sleeve connected with the pre-buried steel bar needs to be disassembled, and the internal connecting components and the main structure need to be blocked in a small area, which has a small influence on the overall structure, ensures the strength, and effectively reduces the risk of water leakage.

[0048] 3) The assembled outer frame wall connecting piece can meet the use in different environments, especially for special-shaped wall structures, has a wide application range, and has universality.

[0049] Obviously, those skilled in the art can make various modifications and changes to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and changes of the utility model belong to the scope of the claims of the utility model and its equivalent technologies, the utility model also intends to include these modifications and changes.
