Abstract
Description
Technical Field
[0001] This application relates to the technical field of building restoration, and particularly to a reinforcement method for beam-columns at deformation joints. Background Art
[0002] In the renovation project of existing buildings, it is often necessary to reinforce the beam-column structures on both sides of the structural deformation joint. Currently, there are the following common methods for beam-columns:
[0003] 1. Reinforcement by increasing cross-section: For beam-columns at deformation joints, unilateral, bilateral or trilateral cross-section increase can be adopted. This reinforcement method has two disadvantages: one is that the cross-section of the component increases significantly, which affects the building function; the other is that the steel bars are asymmetrically arranged during reinforcement, resulting in uneven stress and low utilization rate of some steel bars. Therefore, this reinforcement method is rarely used at present.
[0004] 2. External bonding of steel shapes: Angle steels are externally bonded at the four corners, and then the angle steels are connected by hoop bars. This reinforcement method results in less increase in the cross-section of the component and controllable cost, and is currently widely used. However, since this reinforcement method requires chiseling and grinding the original concrete base surface of the beam-column to install the angle steels, and the angle steels and hoop bars need to be welded, and the joints need to be sealed and grouted, this reinforcement method is usually applied to independent beam-columns with a large construction operation space around. According to building standards, double beams and double columns are usually required to be adjacent to the deformation joint, which results in extremely narrow space (generally between 100 and 200 mm) on one side of the deformation joint, and basically no construction operation space. Therefore, the construction difficulty is relatively large.
[0005] 3. Carbon fiber sheet bonding reinforcement: The column is reinforced by carbon fiber hoop bars around, and the beam is reinforced by bonding carbon fiber at the bottom of the beam or carbon fiber hoop bars. This reinforcement method, like the external bonding of steel shapes reinforcement method, has no construction space on one side of the deformation joint, cannot grind the base layer, and cannot ensure that the carbon fiber is bonded without air pockets. Summary of the Invention
[0006] The purpose of this application is to solve the problem of difficult construction for beam-column reinforcement at deformation joints in the prior art. Therefore, this application provides a reinforcement method for beam-columns at deformation joints. By using connecting rods to reinforce the near-joint side, there is no need to treat the base layer of the near-joint side and fill the joint, the requirement for construction space is small, the construction difficulty is reduced, and it is suitable for beam-column reinforcement at deformation joints.
[0007] An embodiment of this application provides a reinforcement method for beam-columns at deformation joints. The beam or column includes a near-joint side and a far-joint side, and the method includes:
[0008] Treating the base layer: Chiseling and grinding the surface of the far-joint side of the beam or column;
[0009] Surrounding and installing a reinforcement device: The reinforcement device includes a far-seam-side reinforcement component and a near-seam-side reinforcement component; the far-seam-side reinforcement component is surrounded and wrapped around the far-seam side of the beam or column. Among them, two first connecting plates in the far-seam-side reinforcement component are closely attached to the two far-seam sides connected to the near-seam side, and the extending parts of the two first connecting plates both extend into the deformation joint; the connecting rod of the near-seam-side reinforcement component penetrates through the extending parts of the two first connecting plates and is connected into a whole through a locking piece;
[0010] Filling the joint: Seal and grout the gap between the far-seam-side reinforcement component and the surface of the far-seam side of the beam or column.
[0011] Adopting the above technical solution, the extending parts of the two first connecting plates installed on the far-seam side extend into the deformation joint, and the connecting rod penetrates through the extending parts of the two first connecting plates and is connected into a whole through a locking piece, so as to realize the reinforcement of the near-seam side of the beam or column. And this method does not require base treatment and subsequent joint filling for the near-seam side. At the same time, the connecting rod and the locking piece can be installed from one side of the deformation joint, reducing the construction difficulty and being suitable for the narrow construction space at the deformation joint.
[0012] In some embodiments, the surrounding reinforcement device further includes:
[0013] Install a stiffening plate at the angle between the extending part of the first connecting plate and the near-seam side, and weld one side of the stiffening plate to the extending part of the first connecting plate and abut the other side against the surface of the near-seam side of the beam or column.
[0014] Adopting the above technical solution, the out-of-plane stiffness of the near-seam side is enhanced by the stiffening plate, improving the reinforcement effect. At the same time, the strength of the extending part of the first connecting plate is also enhanced, improving the installation stability and reliability of the connecting rod.
[0015] In some embodiments, the connecting rod is a screw rod, the locking piece is a nut, and the first connecting plate is a hoop plate.
[0016] In some embodiments, when reinforcing a rectangular column, before installing the two first connecting plates, it further includes:
[0017] Wrap angle steel around the edges of the far-seam side of the column, and connect the adjacent angle steels by welding a second connecting plate;
[0018] Install first reinforcement plates on the surfaces of the two far-seam sides connected to the near-seam side, and make the end faces of the first reinforcement plates flush with the surfaces of the near-seam side;
[0019] Cover the two first connecting plates on the corresponding first reinforcement plates and angle steels respectively, and make their extending parts extend into the deformation joint, and weld the end away from the extending part to the corresponding angle steel.
[0020] Adopting the above technical solution, the reinforcement of the far-seam side of the rectangular column is formed by the first connecting plate, the second connecting plate, the first reinforcement plate and the angle steel. This method is similar to the conventional external bonding of steel shape reinforcement method, with stable and reliable construction technology and low difficulty. At the same time, for one side of the column corner near the deformation joint, the first reinforcement plate provides the installation foundation for the connecting plate and enhances the out-of-plane stiffness. On the other side, the extending part of the first connecting plate extending outwards provides the installation foundation for the connecting rod, so as to take into account the structural reinforcement of both the far-seam side and the near-seam side.
[0021] In some embodiments, the angle steel is an equal-angle steel, and the material and size of the first reinforcement plate are the same as the material of the angle steel and the size of its side plate.
[0022] In some embodiments, when reinforcing a rectangular beam, before installing the two first connecting plates, it further includes:
[0023] Install the first reinforcement plate and the second reinforcement plate on the beam top, and make the end face of the first reinforcement plate flush with the surface of the near-seam side. The second reinforcement plate is located at the intersection of the beam and the floor slab;
[0024] Cover the angle steel at the corner of the far-seam side of the beam, and install another second reinforcement plate on the side of the beam near the lower part of the floor slab. Connect the angle steel and the second reinforcement plate by welding the second connecting plate;
[0025] Install the first anchor bolt so that the first anchor bolt penetrates through the second reinforcement plate on the beam top and the corresponding position of the floor slab, and weld its end to the second connecting plate;
[0026] Install another first reinforcement plate at the beam bottom, and make the end face of the first reinforcement plate flush with the surface of the near-seam side;
[0027] Cover the two first connecting plates on the first reinforcement plate and the second reinforcement plate on the beam top, and the first reinforcement plate and the angle steel at the beam bottom respectively, and weld them, and make the extending part of the first connecting plate extend into the deformation joint.
[0028] Adopting the above technical solution, the reinforcement of the far-seam side of the rectangular beam is formed by the first connecting plate, the second connecting plate, the first reinforcement plate, the second reinforcement plate, the angle steel and the first anchor bolt. This method is similar to the conventional external bonding of steel shape reinforcement method, with stable and reliable construction technology and low difficulty. At the same time, for one side of the beam corner near the deformation joint, the first reinforcement plate provides the installation foundation for the connecting plate and enhances the out-of-plane stiffness. On the other side, the extending part of the first connecting plate extending outwards provides the installation foundation for the connecting rod, so as to take into account the structural reinforcement of both the far-seam side and the near-seam side.
[0029] In some embodiments, when reinforcing a rectangular column, when the far-seam side reinforcement assembly surrounds and covers the far-seam side, it further includes:
[0030] Install the third connecting plate on the far-seam side that is not connected to the near-seam side;
[0031] The two first connecting plates and the third connecting plate are welded in sequence, or connected to the column by fasteners.
[0032] The adoption of the above technical solution further reduces the construction difficulty.
[0033] In some embodiments, when reinforcing a rectangular beam, an end of a first connecting plate installed on the top of the beam away from the extension portion extends to the intersection of the beam and the floor slab; and surrounding and covering the far seam side reinforcement assembly on the far seam side also includes:

[0051] In the renovation project of existing buildings, the situation of beam-column reinforcement often occurs. In the conventional case, the space around the beam and column is large, the construction obstruction is small, which is convenient for the surface base treatment of the beam and column and the installation of components, etc. However, for the beam and column on both sides of the structural deformation joint 1, since the width of the deformation joint 1 is usually 100 - 200 mm, the space between adjacent beam and column is extremely narrow, which greatly increases the construction difficulty of the base treatment and the installation of components, etc., and it is easy to cause the construction operation to be not in place, resulting in insufficient stiffness on this side after reinforcement.
[0052] The beam and column at the deformation joint 1 includes the near-joint side close to the deformation joint 1 (that is, the opposite side of the two beams 3 or columns 2) and the far-joint side relatively far from the deformation joint 1. Taking the rectangular beam 3 or rectangular column 2 as an example, among the four sides, the side directly facing and close to the deformation joint 1 is the near-joint side, and the other three sides are the far-joint side, and the two sides are connected to the near-joint side, and the other side is opposite to the near-joint side.
[0053] Example 1:
[0054] The embodiment of this application provides a reinforcement method for the beam and column at the deformation joint, including treating the base, enclosing the reinforcement device, and filling the joint. Specifically,
[0055] Treating the base:
[0056] Chisel and polish the surface of the far-joint side of the beam 3 or column 2.
[0057] The base treatment is similar to the conventional external bonding of steel reinforcement method. Generally, it is necessary to thoroughly remove the plaster layer on the surface of the original structure, roughen the concrete until the aggregate is exposed, wipe off the oil stains and dust with acetone, and grout or repair the cracks or defects to ensure the base is flat, so as to facilitate the installation of the reinforcement components in the subsequent construction operations, facilitate their close fit with the main structure, and enhance the rigidity of the beam-column.
[0058] Meanwhile, due to the larger construction space on the far-side of the joint, the base treatment is less difficult and the treatment effect can be ensured.
[0059] Surround and install the reinforcement device:
[0060] The reinforcement device includes a far-side reinforcement component and a near-side reinforcement component. Among them, the far-side reinforcement component includes two first connecting plates 10, and the first connecting plates 10 have protruding parts. The near-side reinforcement component includes a connecting rod 30 and a locking member 31.
[0061] Surround and cover the far-side of the beam 3 or column 2 with the far-side reinforcement component to achieve reinforcement of the far-side. And during construction, the two first connecting plates 10 are installed close to the two far-sides connected to the near-side (for example, bonded), and the protruding parts of the two first connecting plates 10 both extend into the deformation joint 1.
[0062] Pass the connecting rod 30 of the near-side reinforcement component through the protruding parts of the two first connecting plates 10 and connect them into one body through the locking member 31, so as to achieve reinforcement of the near-side through the connecting rod 30, and form an integral body of the near-side reinforcement component and the far-side reinforcement component through being connected into one body, improving the overall reinforcement effect on the beam-column.
[0063] Moreover, this method does not require base treatment and subsequent joint filling on the near-side. At the same time, the connecting rod 30 and the locking member 31 can be installed from one side of the deformation joint 1, reducing the construction difficulty and being suitable for the narrow construction space at the deformation joint 1.
[0064] Joint filling:
[0065] Seal and grout the gap between the surface of the far-side reinforcement component and the far-side of the beam 3 or column 2 to form a joint filling layer 40, so as to further improve the connection reliability between each component and the overall reinforcement effect on the beam-column. And the construction space on the far-side is larger, the joint filling is less difficult, and the joint filling effect can be ensured.
[0066] This method not only facilitates the construction operation on the near-side of the beam-column, but also has less increase in cross-section after reinforcement and little impact on the building function.
[0067] In one embodiment, the surrounding reinforcement device further includes:
[0068] A stiffening plate 32 is installed at the angle between the protruding part of the first connecting plate 10 and the near-seam side, and one side of the stiffening plate 32 is welded to the protruding part of the first connecting plate 10, and the other side abuts against the surface of the near-seam side of the beam 3 or column 2, so as to enhance the out-of-plane stiffness of the near-seam side, improve the reinforcement effect, and at the same time enhance the strength of the protruding part of the first connecting plate 10, and improve the installation stability and reliability of the connecting rod 30.
[0069] In one embodiment, the connecting rod 30 is a screw rod, the locking member 31 is a nut, and the first connecting plate 10 is a hoop plate.
[0070] Example 2:
[0071] Please refer to Figure 1 , Figure 1 which is a construction schematic diagram when the column 2 is reinforced by the reinforcement method provided in Embodiment 2 of the present application.
[0072] On the basis of Embodiment 1, this embodiment is especially for the reinforcement of the rectangular column 2.
[0073] When reinforcing the rectangular column 2, before installing the two first connecting plates 10, it further includes:
[0074] Angle steels 20 are covered on the edges of the far-seam side of the column 2, and the adjacent angle steels 20 are connected by welding the second connecting plate 21. The second connecting plate 21 is preferably a hoop plate.
[0075] First reinforcing plates 22 are installed on the surfaces of the two far-seam sides connected to the near-seam side, and the end faces of the first reinforcing plates 22 are flush with the surfaces of the near-seam side, so as to facilitate the installation of the stiffening plate 32.
[0076] The two first connecting plates 10 are respectively covered on the corresponding first reinforcing plates 22 and angle steels 20, and their protruding parts extend into the deformation joint 1, and the ends away from the protruding parts are welded to the corresponding angle steels 20.
[0077] This method forms the reinforcement of the far-seam side of the rectangular column 2 through the first connecting plate 10, the second connecting plate 21, the first reinforcing plate 22 and the angle steel 20. This method is similar to the conventional external bonded steel reinforcement method, and the construction process is stable, reliable and has low difficulty.
[0078] At the same time, for one side of the edge of the column 2 close to the deformation joint 1, the first reinforcing plate 22 provides a connecting plate installation foundation and enhances the out-of-plane stiffness, and the other side provides a connecting rod 30 installation foundation through the protruding part extending outward of the first connecting plate 10, so as to take into account the structural reinforcement of the far-seam side and the near-seam side, and this side does not require grinding, sealing and grouting treatment.
[0079] In one embodiment, the angle steel 20 is an equal-leg angle steel 20, that is, it includes two identical side plates. Preferably, the material and size of the first reinforcing plate 22 are the same as those of the angle steel 20 and the size of its side plates, so as to reduce the difficulty of component design.
[0080] In one embodiment, the connecting rod 30 is such that its cross-sectional area × strength = the cross-sectional area × strength of the second connecting plate 21 installed on the far-side joint side opposite to the near-side joint side, so as to improve the uniform force bearing of the beam-column and further improve the processing effect.

[0085] Install the first reinforcing plate 22 and the second reinforcing plate 24 on the top of the beam 3, and make the end face of the first reinforcing plate 22 flush with the surface of the near-side joint side, and the second reinforcing plate 24 is located at the intersection of the beam 3 and the floor slab 4.
[0086] Cover the angle steel 20 at the edge angle of the far-side joint side of the beam 3, and install another second reinforcing plate 24 on the side of the beam 3 close to the lower part of the floor slab 4, and connect the angle steel 20 and the second reinforcing plate 24 by welding the second connecting plate 21.
[0087] Install the first anchor bolt 23 so that the first anchor bolt 23 penetrates through the second reinforcing plate 24 on the top of the beam 3 and the corresponding position of the floor slab 4, and weld its end to the second connecting plate 21.
[0088] Install another first reinforcing plate 22 at the bottom of the beam 3, and make the end face of the first reinforcing plate 22 flush with the surface of the near-side joint side.
[0089] Cover the two first connecting plates 10 on the first reinforcing plate 22 and the second reinforcing plate 24 on the top of the beam 3, and the first reinforcing plate 22 and the angle steel 20 at the bottom of the beam 3 respectively, and weld them, and make the protruding part of the first connecting plate 10 extend into the deformation joint 1.
[0090] This method forms the reinforcement of the far-side joint side of the rectangular beam 3 through the first connecting plate 10, the second connecting plate 21, and the first reinforcing plate 22, the second reinforcing plate 24, and the angle steel 20. This method is similar to the conventional external bonded steel reinforcement method, and the construction process is stable, reliable, and has low difficulty.
[0091] Meanwhile, for one side of the corner of the beam 3 near the deformation joint 1, the first reinforcement plate 22 is used to provide a mounting base for the connecting plate and enhance the out-of-plane stiffness. On the other side, the extending part of the first connecting plate 10 extending outwards provides a mounting base for the connecting rod 30, so as to take into account the structural reinforcement of both the far-side and near-side of the joint.
