Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction connection, in particular to a connection structure for a composite beam and a cast-in-place column. Background Art

[0002] The combined beam is a new type of structure developed on the basis of steel structure and concrete structure. It mainly sets shear connectors between the steel beam and the concrete flange plate to resist the lifting and relative sliding of the two at the interface, so that they can work together as a whole. The cast-in-place column refers to the column that is made on site by transporting materials such as concrete to the site on the basis of the construction of the building. It is usually one of the structural support items of the building and is responsible for bearing and supporting. The connection structure is used to connect the combined beam and the cast-in-place column components.

[0003] However, during the installation process of the existing connection structure between the combined beam and the cast-in-place column, the combined beam and the cast-in-place column are fixed with bolts, and the combined beams do not form traction with each other, which leads to the connection parts between the combined beams and the combined beams and the cast-in-place columns being easily loosened, resulting in a short service life of the connection structure between the combined beam and the cast-in-place column. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a connection structure for composite beams and cast-in-place columns to solve the problem that the connection components between the existing composite beams and composite beams and between composite beams and cast-in-place columns are prone to loosening, resulting in a short service life of the connection structure between composite beams and cast-in-place columns.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a connection structure for composite beams and cast-in-place columns, comprising a cast-in-place column seat, the bottom of the cast-in-place column seat is fixedly connected to a support column, the bottom end of the support column is fixedly connected to a foundation, the top of the cast-in-place column seat is provided with a mounting groove, the top of the mounting groove is fixedly connected to a fixing rod, the top of the fixing rod is threadedly connected to a fixing nut, the inner side of the mounting groove is fixedly connected to a composite beam body through the fixing rod, the top of the composite beam body is provided with a connecting groove, the inner side of the connecting groove is fixedly connected to a connecting frame, the top of the inner side of the connecting groove is provided with a fixing groove, both sides of the composite beam body are fixedly connected to connecting beams, and one end of the connecting beam is threadedly connected to a connecting screw.

[0006] Preferably, a buffer plate is installed between the composite beam body and the column seat, and the buffer plate is made of rubber material.

[0007] Preferably, the connection frame gradually becomes smaller from the outside to the inside, and the outer width of the connection frame is matched with the inner width of the connection groove.

[0008] Preferably, the foundation includes support columns at the top of the foundation and column seats connected to the tops of the support columns, which are cast in one piece.

[0009] Preferably, the composite beam body and the connecting beam are an integrated structure, and both the composite beam body and the connecting beam are made of concrete.

[0010] Preferably, the fixing rod is movably connected to the fixing groove, and the fixing rod passes through the bottom of the fixing groove.

[0011] The utility model provides a connection structure for composite beams and cast-in-place columns, which has the following beneficial effects:

[0012] The utility model provides a connecting beam, a connecting screw, a connecting groove and a connecting frame. When installing the composite beam and the cast-in-place column, the staff installs the composite beam body in the installation groove, inserts the fixing rod into the fixing groove, and then installs the second composite beam body in the installation groove in this way, and inserts the connecting screw through the two connecting beams, and tightens the connecting screw with a nut. At this time, the connecting screw will pull the connecting beam to combine the two composite beam bodies, and then fix the fixing nut on the fixing rod, and install the connecting frame in the connecting groove. Because the connecting frame gradually becomes smaller from the outside to the inside, the connecting frame can play a role of pulling the two composite beam bodies when installed in the connecting groove, thereby avoiding the connection parts between the composite beams and the composite beams and the composite beams and the cast-in-place columns from being easily loosened, thereby improving the service life of the connection structure between the composite beam and the cast-in-place column.

[0020] In this embodiment, a buffer plate 10 is installed between the composite beam body 5 and the column seat 3. The buffer plate 10 is made of rubber material, so that the buffer plate 10 can play a role in buffering and seismic isolation, ensuring that the upper and lower structures are not disconnected during horizontal and vertical earthquakes.

[0021] In this embodiment, the connecting frame 13 gradually becomes smaller from the outside to the inside, and the outer width of the connecting frame 13 is adapted to the inner width of the connecting groove 8, so that the connecting frame 13 can play a role in pulling the two composite beam bodies 5 when installed in the connecting groove 8.

[0022] In this embodiment, the foundation 1 includes the support column 2 on the top of the foundation 1 and the column seat 3 connected to the top of the support column 2, which are cast in one piece, which is convenient for the construction of the combined beam, so that the combined beam can be cast and manufactured in one time.

[0023] In this embodiment, the composite beam body 5 and the connecting beam 6 are an integrated structure, and both the composite beam body 5 and the connecting beam 6 are made of concrete, which is convenient for the construction of the cast-in-place column, so that the cast-in-place column can be cast in one go.

[0024] In this embodiment, the fixing rod 11 is movably connected to the fixing groove 9, and the fixing rod 11 passes through the bottom of the fixing groove 9, so that the two composite beam bodies 5 can move inward normally during adjustment.

[0025] Working principle: when installing the composite beam and the cast-in-place column, the staff installs the composite beam body 5 in the installation groove 4, inserts the fixing rod 11 into the fixing groove 9, and then installs the second composite beam body 5 in the installation groove 4 in this way, and inserts the connecting screw 7 through the two connecting beams 6, and uses a nut to tighten the connecting screw 7. At this time, the connecting screw 7 will pull the connecting beam 6 to merge the two composite beam bodies 5, and then use the fixing nut 12 to fix it on the fixing rod 11, and install the connecting frame 13 in the connecting groove 8. Because the connecting frame 13 gradually becomes smaller from the outside to the inside, the connecting frame 13 can play a role of pulling the two composite beam bodies 5 when it is installed in the connecting groove 8, thus completing the use process of the utility model. The utility model has a simple structure and is safe and convenient to use.
