FIG 1
The present invention belongs to the technical field of structural engineering, and
particularly relates to an assembled structural connector.
Common construction methods for existing concrete structures can be divided
into three types: cast-in-place, assembled, and assembled integral. The cast-in-place
structure is a structural system in which all components are formed by in-place
formwork constructing, in-place concrete pouring and in-place maintenance. Although
this method has good overall performance and shock resistance, a great amount of
concrete is poured, a lot of formwork is consumed, and the construction time is long;
moreover, this method is easily influenced by external factors and creates a great deal
of environmental pollution. The assembled structure is a structural system in which all
components are prefabricated in the factory and assembled in-place, and the joint
connection area is often connected by welding or bolt connection. Although this
method saves the formwork and construction time, the overall performance and shock
resistance of the structure are poor because it includes many prefabricated
components and the joint connection area is not formed by in-place concrete pouring.
In the so-called assembled integral structure, some components are prefabricated in
the factory, other components are cast in-place, and the joint area is often connected
by means of grouting sleeve connection or grouting-anchoring overlap-joint, which
enhances the structural integrity and makes up for the shortcomings of the
cast-in-place structure, so currently it is the commonly used assembled structure
construction technology. However, in this method, the connection joints involve many
non-standard components, the construction process is complicated, and the grouting
mortar filling rate of the grouting machine is not easy to control, so it is prone to
incomplete filling and unreliable connection, and will very likely to leave hidden dangers for the safe use of the structure. Therefore, there is a need for a new, standardized, assembled structural connector to solve or at least mitigate the above problems.

with the filling material.
In some preferred embodiments, the penetrating member includes a bolt, the
locking member includes two nuts disposed on the bolt and matched with the bolt, the
two nuts are located on each side of the flush structure, respectively, and the bolt has
an elongated portion extending outside at least one nut.
In some preferred embodiments, the bolt has an elongated portion extending
outside the nut, and an end of the elongated portion away from the nut does not extend
beyond the prefabricated steel member in a thickness direction of the prefabricated
steel member.
In some preferred embodiments, the prefabricated shaped member is an I-shaped

present invention. FIG. 3 is a schematic view of an overall structure of an assembled
structural connector according to an embodiment of the present invention. As shown
in FIG. 1 to FIG. 8, preferably, the prefabricated steel member 2 is divided into two
prefabricated special shaped members sequentially arranged in the left-right direction.
FIG. 9 and FIG. 10 show three prefabricated special shaped members sequentially

In the present invention, the prefabricated special shaped members can be integrated with the external structure, that is, be integrally formed, thereby saving materials and costs. Specifically, as shown in FIG. 2 which is an exploded schematic view of the integration of the prefabricated special shaped member 2b and the external structure, and FIG. 3 which is an assembled schematic view of the integration of the prefabricated special shaped member 2b and the external structure, those skilled in the art can flexibly set the length, size and shape of the external structures connected with the left and right prefabricated special shaped members according to the practical applications. The external structure can be a common assembled type structure such as a beam, a column and a shear wall, as long as the upper and lower assembly end faces on the two opposed prefabricated shaped members are parallel and the opposed special shaped joints are matched. The examples of them will not be given here in detail. The arrangement of the three special shaped joints in the present embodiment is shown in FIG. 4 and FIG. 5. The special shaped joints 21 of the present invention may have a shape of arc, rectangle, triangle, sphere or other shapes. The shape of the special shaped joints 21 may also be a combination of multiple shapes. Referring to
FIG. 9, the shapes of the three shaped joints 21 on the same prefabricated shaped
member may also be different from each other. The shape of the special shaped joints
on the I-shaped web of the prefabricated shaped member in FIG. 9 may also be a
combination of multiple shapes. In order to simplify the description, the present
embodiment only illustrates arc-shaped joints in the drawings, and those skilled in the
art can flexibly design the shapes of the special shaped joints of the present invention
according to the practical applications. This adjustment of the shape of joint does not
depart from the principle and scope of the present invention, and should be within the
protection scope of the present invention.
The prefabricated steel member 2 of the assembled structural connector of the
present invention is preferably an I-shaped structure, and its specific structure is
shown in FIG. 3 and FIG. 4. The I-shaped steel structure has strong bending resistance
and light weight, saves materials, labor and time, and is convenient to assemble. It can
be understood that, it is only an exemplary description that the number of shaped
joints 21 on the end of one side of the prefabricated shaped member is three, and those
skilled in the art can adjust the number as required in order to adapt to specific
application scenarios. The technical solution after adjusted shall still fall within the
protection scope of the present invention. For example, two, four, five, or more
special shaped joints 21 may be provided. Further, the I-shaped structure comprises
two wings and a web, and two ends of the web are respectively connected to the
centers of the two wings. The I-shaped may be formed by integrally forming the two
wings and the web. The wings and web of the I-shaped structure are provided with
special shaped joints. In such an arrangement, the construction worker can arbitrarily
choose any one of the special shaped joints to assemble during construction and
assembly so that the assembly of all the special shaped joints on the I-shaped structure
can be completed, which ensures the flushness of the structure, and the construction
worker does not need to repeatedly adjust to make the structure flush. Referring to
FIG. 9, the special shaped joint of the present invention can also be assembled in combination. In addition, the special shaped joint 21 may be fixed to the end of the prefabricated special shaped member by mechanical connection or welding connection after the prefabricated special shaped member is manufactured. Alternatively, a part of the special shaped joint 21 and the prefabricated special shaped member may be integrally formed in the manufacturing stage of the prefabricated special shaped member. The present invention can reduce the difficulty of connecting the prefabricated special shaped members 2 through the design of the I-shaped steel plate and the special shaped joints on the steel plate. Two matched I-shaped prefabricated steel members can be installed with accuracy and flushness via the easy assembly of special shaped joints, and the construction worker does not need to calibrate again, which simplifies the operation process, reduces the technical requirements for the construction worker, and improves the construction efficiency. Continuing to refer to FIG. 3, preferably, the two special shaped joints 21 in the joint unit 4 abut against each other on their adjacent sides to form a seamless flush structure, both sides of the flush structure are provided respectively with the prefabricated steel plates 1, and a plurality of the fastening devices 3 penetrate the seamless flush structure and the prefabricated steel plates 1. The left and right special shapedjoints 21 in the joint unit 4 abut against each other. Preferably, the joint portion further comprises a filler material, which is poured into the joint portion and is flush with an external structure connected with the prefabricated steel member 2. The filler material may be concrete or otherfiller materials for construction. Specifically, after the prefabricated steel members 2 arranged on the left and right are assembled in place and the special shaped joints 21 are fixedly connected via the fastening device 3 and the prefabricated steel plate 1, the concrete is poured into the joint portion and filled to be flush with an external structure connected with the prefabricated steel member 2. When the concrete is solidified, it will be integrated with the assembled structural connector of the present invention. By pouring the filling material into the joint portion, the two opposite prefabricated shaped members can be further connected together by the filling material. By providing the filling material, the connection strength and integrity of the joint portions of the two opposed prefabricated special shaped members are improved, and the internal rigid structural members are protected from corrosion. FIG. 2 shows the structure of the fastening device in the assembled structural connector of the present invention. As shown in FIG. 2, the fastening device 3 comprises a penetrating member and a locking member. The penetrating member cooperates with the locking member to fixedly connect the special shaped joint 21 with the corresponding prefabricated steel plate 1; the penetrating member can also be used to cooperate and fix with the filling material. Preferably, the penetrating member includes a bolt 31, as specifically shown in FIG. 1. The drawings of the present invention are only for understanding the technical solution of the present invention. In order to simplify the structure and facilitate understanding, threads of the bolt are not shown in the drawings. The locking member includes two nuts 32 disposed on the bolt 31 and matched with the bolt 31. The two nuts 32 are located on both sides of the flush structure, respectively. The bolt 31 extends outside one of the nuts 32 and has an elongated portion. The end of the elongated portion which is away from the nut 32 does not extend beyond the prefabricated steel member in the thickness direction of the prefabricated steel member. The bolts 31 in each joint unit 4 are divided into two portions: the elongated portion of some bolts 31 is located at the lower side of the joint unit 4, and the elongated portion of other bolts 31 is located at the upper side of the joint unit 4, so that the joint portion and the filling material are reliably combined and fixed together. It can be understood by those skilled in the art that the bolt 31 may also extend beyond the nut 32s and have an elongated portion at both sides.
With such an arrangement, the fastening device fixedly connects the two special
shaped joints 21 in the joint unit 4 with the assistance of the prefabricated steel plate 1;
moreover, the penetrating member of the fastening device 3 is fixed and combined
with the filler material, which increases the stability of the filler material and
reliability, thereby further improving the connection reliability of the joint portion and
extending the service life. The fastening device is provided in a form in which the bolt
31 cooperates with the nut 32, which facilitates the installation of the fastening device
3. The bolt 31 has an elongated portion extending outside one of the nuts 32, and the same number of elongated portions is evenly distributed on both sides of the joint unit
4. The elongated portions can make the filling material on both sides of the joint unit
4 to be evenly stressed, thereby further improving the strength and reliability of filler
materials. Those skilled in the art can understand that the bolt 31 may not be provided
with an elongated portion extending outside the nut 32. Preferably, the bolt 31 can be
formed integrally with the nut 32. In the present embodiment, the bolt 31 is formed
integrally with the nut 32, that is, high-strength bolts and matching nuts are used as
fastening devices in the present invention to ensure the connection performance of
special shaped joints. The design of the present embodiment can reduce construction
steps of the construction worker and improve efficiency.
