Description

TECHNICAL FIELD

[0002] With the development of the building level, people's living standards improve, and the trend of commercial development driving the surrounding economic development is more and more obvious. In the development of commercial buildings, the use of special effects to improve the commercial value is becoming more and more common, and the structure design needs to use cantilever structure to achieve special effects, and the cantilever structure becomes a construction difficulty.

[0003] In the prior art, the cantilever structure is generally reinforced by a support, such as a reinforcing structure for a concrete cast-in-place beam Bailey cantilever disclosed in CN215210557U, which comprises a fixed structure located at the top of the completed concrete cast-in-place beam and fixedly connected thereto; a connecting structure comprising a plurality of ropes for connecting the fixed structure and the Bailey cantilever portion, the ropes being connected to a winding device for adjusting the tension of the ropes.

[0004] This reinforcing structure uses ropes and pre-embedded bars to connect the Bailey piece and the cantilever beam, but there is no connection between the cantilever beam and the Bailey piece. The cantilever beam is not stable enough due to the floating arrangement, and when the length of the cantilever beam is too long, the cantilever beam is easily deformed and bent in the vertical direction due to the influence of gravity, thereby weakening the reinforcing effect of the ropes on the cantilever beam. At the same time, the ropes are used to reinforce the cantilever beam, and due to the softness of the ropes, the effect of resisting deflection deformation of the cantilever beam is poor, and the fixing effect has a lot of room for improvement.

[0033] In order to embody the creativity of the reinforcing structure 4, the cantilever beam 7 is integrally formed with the wall body 1 by casting, and the connection between the cantilever beam 7 and the wall body 1 is strengthened by the reinforcing structure 4; the wall body 1 and the cantilever beam 7 are internally provided with the same I-beam 6, which can strengthen the connection between the wall body 1 and the cantilever beam 7, and meanwhile the cantilever beam 7 is easily affected by its own gravity to produce deflection deformation in the vertical direction, and the I-beam 6 built in the cantilever beam 7 can resist this deformation to a certain extent, thereby prolonging the service life of the cantilever beam 7; the mounting plate 42 built in the wall body 1 is fixedly connected with the I-beam 6 by brazing, further strengthening the connection between the I-beam 6 and the wall body 1, and the mounting plate 42 is in close contact with the surface of the I-beam 6 through the connecting rods 43 and the extrusion blocks 44, and when the I-beam 6 resists the deflection deformation of the cantilever beam 7 in the vertical direction, the I-beam 6 will also produce deflection deformation in the vertical direction when it reaches the deflection limit, and the extrusion blocks 44 on both sides can generate force on the I-beam 6, and the connecting rods 43 connected with the extrusion blocks 44 are fixedly connected with the mounting plate 42 through the fixing nuts 47, thereby playing a certain auxiliary effect on resisting the deflection deformation of the I-beam 6; when the I-beam 6 and the cantilever beam 7 produce bending deformation in the vertical direction, the horizontal plate above the I-beam 6 will drive the two extrusion blocks 44 to move, thereby enabling the two connecting rods 43 to move in the empty grooves 45, and the shape of the two empty grooves 45 is an "eight" shaped arc groove, and in the initial state, the connecting rods 43 are located at the bottom of the empty grooves 45, and the bending of the I-beam 6 enables the connecting rods 43 to move above the mounting plate 42 and simultaneously approach the center of the mounting plate 42, and the connecting rods 43 approaching the center increase the friction between the extrusion blocks 44 and the I-beam 6, thereby playing a deformation resisting effect. The reinforcing structure 4 is internally provided with the same I-beam 6 in the wall body 1 and the cantilever beam 7, the I-beam 6 is fixedly connected with the mounting plate 42 built in the wall body 1 by brazing, the extrusion blocks 44 connected on both sides of the mounting plate 42 drag the surface of the I-beam 6, the connecting rods 43 connected with the extrusion blocks 44 are fixed through the fixing nuts 47, and the connecting rods 43 are arranged in the empty grooves 45, all of which can play a reinforcing effect on the connection between the wall body 1 and the cantilever beam 7 and on reducing the deflection deformation of the cantilever beam 7 and the I-beam 6.

[0035] When the length of the cantilever beam 7 is too long, the cantilever beam 7 is prone to stress deformation, and the body is usually formed by separate casting, which divides the cantilever beam 7 into a first casting part 2 and a second casting part 3, and the casting of the cantilever beam 7 is completed by separating the first casting part 2 and the second casting part 3 through the construction opening 8; in order to ensure the creativity of the connecting structure 5, the I-beam 6 is arranged directly below the construction opening 8, so that the I-beam 6 is arranged inside the first casting part 2 and the second casting part 3, and plays a stabilizing role in the connection between the first casting part 2 and the second casting part 3; when resisting the deflection deformation of the cantilever beam 7 in the vertical direction, the I-beam 6 will also produce deflection deformation to the both sides of the cross section, and the I-beam 6 is welded with a plurality of additional ribs 52, and the horizontal ribs 54 welded at the top and bottom of the additional ribs 52 can reduce the horizontal deflection deformation of the cross section of the I-beam 6.

[0036] The reinforcing structure 4 and the connecting structure 5 can resist the deflection deformation of the formed cantilever beam 7; during the casting and forming of the cantilever beam 7, the I-beam 6 with the reinforcing structure 4 and the connecting structure 5 is pre-embedded, so that the cantilever beam 7 can reduce deformation during casting and forming, thereby making the formed cantilever beam 7 have stronger stress.

[0037] The I-beam 6 is arranged from the connection between the wall body 1 and the cantilever beam 7 to the second casting part 3, and when the I-beam 6 is too long, the effect of resisting deformation of the I-beam 6 will be poor.

[0038] Further, the I-beam 6 can be replaced by a fixed I-beam 41 and a connecting I-beam 51. Please refer to Figure 6 As shown in the figure, the fixed I-beam 41 is arranged at the connection between the wall body 1 and the second casting part 3, the fixed I-beam 41 is fixedly connected with the mounting plate 42 through brazing, the extrusion blocks 44 connected on both sides of the mounting plate 42 are closely attached to the fixed I-beam 41; the connecting I-beam 51 is located directly below the construction opening 8, the connecting I-beam 51 is arranged between the first casting part 2 and the second casting part 3, the surface of the connecting I-beam 51 is fixedly connected with the additional ribs 52 through brazing, the additional ribs 52 at the top and bottom of the connecting I-beam 51 are brazed with the connecting ribs 53, and one end of the connecting ribs 53 is connected with the horizontal horizontal ribs 54; the fixed I-beam 41 and the connecting I-beam 51 replace the I-beam 6 to be fixed inside the wall body 1 and the cantilever beam 7, which can reduce the consumption of materials while achieving the same effect.

[0039] In order to make the fixed I-beam 41 and the connecting I-beam 51 better replace the I-beam 6, the fixed I-beam 41 and the connecting I-beam 51 are located on the central straight line of the cantilever beam 7, and the projections of the fixed I-beam 41 and the connecting I-beam 51 in the horizontal direction can completely coincide.
