[0002] The regulating gate frame is a frame located above the seam pier, which mainly connects the gate tie beam and the gate pier to facilitate the operation of the gate. The frame tie beam is a horizontal beam connected between the columns of the frame, and the stability and safety of the frame are improved by the tie beam. During the long-term use of the existing tie beam, due to the long-term exposure to external forces such as water pressure and wind load, as well as internal factors such as material aging and fatigue damage, its structural performance deteriorates and cracks occur, resulting in the problem of insufficient safety performance of the frame beam. Once the safety performance of the frame is reduced, it will inevitably affect the stability of the operation of the entire water conservancy project and increase the safety threat during use. There are no relevant measures and devices in the prior art that can significantly improve the structural performance of the tie beam to solve the above-mentioned problems. Utility Model Content

[0003] The existing bent frame tie beams are subjected to external forces such as water pressure and wind load, and factors such as material aging and fatigue damage cause their structural performance to decline and cracks to occur, thus causing the problem of insufficient safety performance of the bent frame tie beams, thereby affecting the stability of the entire water conservancy project and posing a threat to the safety of the use process. At least one aspect or one purpose of the present application can solve the above problems, and specifically design a control gate bent frame tie beam maintenance and reinforcement device, and the specific technical solution adopted is:

[0005] Preferably, the reinforced structural plate layer includes a structural plate substrate, the surface of the structural plate substrate close to the interface agent layer is covered with reinforcing strips, the reinforcing strips extend to one side of the structural plate substrate, and the surface of the structural plate substrate close to the slurry layer is provided with a plurality of pyramidal protrusions, the pyramidal protrusions are hollow structures, and the plurality of pyramidal protrusions are horizontally spaced on the structural plate substrate along a circle of the reinforced structural plate layer.

[0006] Preferably, two grooves are provided, the two grooves are spaced apart along the length direction of the frame tie beam, and the two grooves are correspondingly provided near 1 / 4 of the two ends of the frame tie beam.

[0007] Preferably, the reinforcing strip is arranged obliquely relative to the structural plate base.

[0015] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] like Figure 1-2 As shown, a device for repairing and reinforcing the tie beam of a regulating gate frame includes a groove 3 arranged around the side of the frame 1 tie beam 2, and an interface agent layer 4, a reinforcing structure plate layer 5, and a slurry layer 6 are sequentially arranged in the groove 3 from the bottom of the groove 3 to the outer edge of the groove 3, and the three are bonded.

[0018] The above-mentioned interface agent in this application adopts modified epoxy interface adhesive, such as WJ-301 epoxy resin interface adhesive.

[0019] The reinforcing structure plate layer 5 is arranged around the groove 3 and then connected end to end. The reinforcing structure plate layer 5 here can be a plurality of plates connected end to end in sequence to form a whole, or it can be formed by connecting two L-shaped plates end to end to form a whole. The purpose of doing so is to facilitate installation, and it can be directly welded with welding rods without bending the plates on site. Welding into a whole will improve the firmness of the reinforcing structure plate on the tie beam 2 of the bent frame 1.

[0020] The mixed material layer 6 adopts polymer mortar with a strength grade of not less than C30. This kind of mortar belongs to Class I polymer mortar. According to the provisions of the national standard GB50367-2013 "Concrete Structure Reinforcement Design Code", the reinforcement of beams and columns should use Class I polymer mortar.

[0021] Furthermore, the specific structure of the above-mentioned reinforced structural plate layer 5 includes a structural plate matrix 503. The structural plate matrix 503 is made of Q345 flat steel. The surface of the structural plate matrix 503 close to the interface agent layer 4 is welded with reinforcing strips 502. The reinforcing strips 502 extend to one side of the structural plate matrix 503. When the structural plate matrix is ​​bonded to the interface agent, the reinforcing strips 502 can be inserted into the interface agent. At the same time, the surface of the structural plate matrix 503 is also in contact with and bonded to the interface agent, which can further improve the bonding ability. A plurality of pyramidal protrusions 501 are welded on the surface of the structural plate base 503 close to the slurry layer 6, wherein the pyramidal protrusions 501 are triangular pyramidal protrusions, and the pyramidal protrusions 501 are hollow structures. The plurality of pyramidal protrusions 501 are horizontally spaced around the reinforced structural plate layer 5 on the structural plate base 503. Similarly, the protruding pyramidal protrusions 501 can be buried in the slurry when the slurry is used to repair the groove 3, thereby improving the bonding strength between the reinforced structural plate layer 5 and the slurry layer 6, thereby improving the bonding strength with the tie beam 2 of the frame 1 as a whole.

[0022] Furthermore, in order to strengthen symmetrically and improve the reinforcement effect, two grooves 3 are provided, the two grooves 3 are spaced apart along the length direction of the tie beam 2 of the frame 1, and the two grooves 3 are provided at 1 / 4 of the two ends of the tie beam 2 of the frame 1.

[0023] Furthermore, the reinforcing strip 502 is inclined relative to the structural plate substrate 503. The purpose of the inclined setting is to form the hooking force of the reinforcing strip 502. Because the most likely problem between the later repair and reinforcement interface agent and the reinforced structural plate layer 5 is the separation of the cross-sectional layers, and the most direct and effective force leading to the separation is the force in the direction perpendicular to the cross-sectional direction. The reinforcing strip 502 is set to be inclined in order to give it a gripping force and improve the bonding ability of the interface.

[0024] Furthermore, in order to further improve the bonding strength between the reinforced structural plate layer 5 and the slurry layer 6, the length of the above-mentioned pyramidal protrusion 501 is smaller than the width of the structural plate base 503, so that when the polymer mortar is poured into the groove 3, the mortar can enter it from the end of the hollow triangular pyramidal protrusion, so that the inside and outside of the triangular pyramidal protrusion are mixed with the polymer mortar, thereby improving the bonding between the reinforced structural plate layer 5 and the slurry layer 6.

[0025] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0026] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
