Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to a plate-tube composite anchor plate and an anchor rod. Background Art

[0002] In the field of anchor bolt technology, an anchor pad is a force-transmitting member located outside the anchor hole, between the anchor and the concrete structure. Current anchor pads are typically square or circular steel plates. These disadvantages include poor load-bearing conditions (cantilever loads), high bending moments, high stresses, and significant bending deformation. The installation gap between the anchor pad and the concrete structure tends to open at the edges due to the large bending deformation when the anchor bolt is stressed. Groundwater can easily enter through this gap, reaching the anchor bolt body and seeping down along the anchor bolt, corroding the anchor bolt within a certain length below the anchor pad. Summary of the Invention

[0003] The utility model provides a plate-tube composite anchor plate and anchor rod to solve the problems of traditional anchor plate that ground water easily enters through the installation gap and reaches the anchor rod body and penetrates downward along the anchor rod body to corrode the anchor rod and the traditional anchor plate has a relatively low anchoring bearing capacity.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A plate-cylinder composite anchor plate, which includes an anchor plate and a cylindrical component vertically connected to the anchor plate. The plate-cylinder composite anchor plate is used to be embedded in a concrete structure outside the anchor hole. The anchor plate is provided with a rod hole within the range surrounded by the cylinder wall of the cylindrical component. The rod hole is used for the anchor rod to be inserted and locked on the anchor plate.

[0006] Preferably, the plate-cylinder composite anchor plate also includes an anchor, which is fixed to the anchor plate. The wall of the cylindrical component surrounds the anchor, and the anchor is used to connect the anchor rod body after passing through the rod body hole of the anchor plate and lock the anchor rod body on the anchor plate.

[0007] Preferably, at least one water-stop ring is provided around the outer side of the cylindrical component.

[0008] Preferably, an annular wing plate is further provided around the outer side of the cylindrical member, and the annular wing plate is fixedly connected to the outer side of the cylindrical member and is perpendicular to the cylindrical member.

[0009] Furthermore, an anchor rod is provided, comprising an anchor rod body, an anchor and the above-mentioned plate-cylinder composite anchor plate, wherein the anchor rod body is inserted into the rod body hole of the anchor plate, the anchor is connected to the anchor rod body, and the anchor rod body is locked on the anchor plate; the plate-cylinder composite anchor plate is embedded in the concrete structure, and the cylinder wall of the cylindrical component surrounds the anchor.

[0010] Preferably, another anchor rod is provided, comprising an anchor rod body and the above-mentioned plate-tube composite anchor plate with anchor, wherein the anchor rod body passes through the rod body hole of the anchor plate and is connected to the anchor, and the plate-tube composite anchor plate is embedded in the concrete structure.

[0011] Optionally, the cylindrical member is filled with concrete, asphalt or grease.

[0012] The utility model has the following beneficial effects:

[0013] The plate-tube composite anchor plate is embedded in the concrete structure 5, so that the gap between the anchor plate 1 and the concrete structure 5 (the gap between the lower end surface of the anchor plate 1 and the concrete structure 5) is located at a certain depth below the upper surface of the concrete structure 5. Moreover, the three-dimensional structure of the plate-tube composite anchor plate makes it difficult for the gap to open, and it is difficult for ground water to seep into the anchor rod body 3 along this gap, avoiding the defect of the traditional anchor plate and the concrete structure that the gap is easy to open and water enters, causing corrosion to the anchor rod body 3 below the anchor plate 1.

[0014] The plate-tube composite anchor plate is embedded in the concrete structure 5, such as Figure 10 As shown, when the anchor rod body 3 is subjected to the tensile force F, causing the outer periphery of the anchor plate 1 to bend upward, the cylindrical structure 2 will generate a resistance force F1, and the filling material (concrete) 6 in the cylindrical member 2 will generate a distributed resistance force f2. F1 and f2 will generate a reverse bending moment in the anchor plate 1 to prevent the outer periphery of the anchor plate 1 from bending upward, thereby preventing the gap between the anchor plate 1 and the concrete structure 5 from opening.

[0015] like Figure 11 As shown, the annular wing plate 22 of the plate-tube composite anchor plate of the present invention adds a shear-resistant surface B with greater shear bearing capacity to the concrete structure 5. The anti-shear surface A and the anti-shear surface B work together to greatly improve the shear bearing capacity of the concrete structure 5. A smaller anchor plate and concrete structure thickness can be used to meet the design requirements, saving engineering costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is a detailed description of the present invention in conjunction with the accompanying drawings, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be considered as restrictive.

[0032] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 The plate-cylinder composite anchor plate includes an anchor plate 1 and a cylindrical member 2. The cylindrical member 2 is vertically connected to the anchor plate 1, that is, the axis of the cylindrical member 2 is perpendicular to the anchor plate 1. The specific connection method can be that the lower end of the cylindrical member 2 is connected to the upper end of the anchor plate 1, or the anchor plate 1 is embedded in the cylindrical member 2 (not shown). The cylindrical member 2 can be a cylinder, a square cylinder (with a square cross section), or a frustum cylinder (a cylinder with unequal diameters in the upper and lower cross sections). The anchor plate 1 is provided with a rod body hole 11 within the range surrounded by the cylinder wall of the cylindrical member 2. The rod body hole 11 is used for the anchor rod body 3 to be inserted and locked on the anchor plate 1. The plate-cylinder composite anchor plate is used to be embedded in the concrete structure 5 outside the anchor hole 8. Specifically, according to the actual application requirements, it can be fully embedded (see Figure 8 ), the upper end of the wall of the cylindrical component 2 is flush with the upper surface of the concrete structure 5; it can also be semi-embedded, with the upper end of the wall of the cylindrical component 2 higher than the upper surface of the concrete structure 5; it can also be buried embedded. The plate-tube composite anchor plate is embedded in the concrete structure 5, so that the gap between the lower end surface of the anchor plate 1 and the concrete structure 5 is located below the upper surface of the concrete structure 5 at a certain buried depth, and the three-dimensional structure of the plate-tube composite anchor plate makes this gap difficult to open, and it is difficult for ground water to enter and seep along this gap to the anchor rod body 3, avoiding the defect that the gap between the lower end surface of the traditional anchor plate and the concrete structure is easy to open and water ingress causes corrosion to the anchor rod body 3 below the anchor plate 1. The locking method of the anchor rod body 3 and the anchor plate 1 can be welding (see Figure 6 The anchor rod body 3 is fixed to the anchor plate 1 by welding with the welding material pile 7. Alternatively, the upper end of the anchor rod body 3 may be bent and fixed to the anchor plate 1 (not shown). Alternatively, the inner wall of the rod hole 11 may be provided with an internal thread and threadedly connected to the rod body 3 (not shown). Alternatively, a clip may be inserted into the gap between the rod hole 11 and the rod body 3 to form a clamping connection (not shown). Another embodiment ( Figure 7 ) and another embodiment ( Figure 8), a special anchor 4 is used to connect the anchor rod body 3 and lock the anchor rod body 3 on the anchor plate 1. The specific construction process is to first insert the anchor rod body 3 into the rod body hole 11 of the anchor plate 1, and make the upper end of the anchor rod body 3 extend upward from the rod body hole 11 to the designed length, embed the plate-tube composite anchor plate into the concrete structure 5, and after the concrete structure 5 solidifies and reaches the designed strength, put the anchor 4 on the upper end of the anchor rod body 3 to connect and lock it on the anchor plate 1.

[0033] See also Figure 3 、 Figure 5 、 Figure 9 The plate-tube composite anchor plate also includes an anchor 4. The wall of the cylindrical member 2 surrounds the anchor 4. The anchor 4 is used to connect the anchor rod 3 after passing through the rod hole 11 of the anchor plate 1. In the illustrated embodiment, the connection is achieved through the connection hole 41 of the anchor 4. The anchor 4 is fixed to the anchor plate 1 and is used to lock the anchor rod 3 to the anchor plate 1. The anchor 4 can be fixed to the anchor plate 1 by welding.

[0034] See also Figure 4 and Figure 8 At least one waterstop ring 21 is also disposed around the sidewall of the cylindrical member 2 of the plate-tube composite anchor plate. This waterstop ring 21 surrounds the outer side of the cylindrical member 2. It is typically made of a rubber ring, copper ring, or other water-swelling material with a certain degree of elasticity. The plate-tube composite anchor plate is embedded within the concrete structure 5. The waterstop ring 21 within the concrete structure 5 effectively prevents water from seeping downward from the interface between the concrete structure 5 and the outer wall of the cylindrical member 2, potentially corroding the anchor rod 3 beneath the anchor pad 1.

[0035] See also Figure 5 、 Figure 9 and Figure 11The plate-tube composite anchor plate has an annular wing plate 22 disposed around the outer wall of the cylindrical member 2. The annular wing plate 22 is perpendicular to the cylindrical member 2 and is embedded in the concrete structure 5. The annular wing plate 22 is located within the concrete structure 5, thereby increasing the shear resistance of the concrete structure 5. Conventional anchor plates lack annular wing plates 22, and the concrete structure 5 has only one shear-resistant surface A, with a height of H1. In this embodiment, the provision of the annular wing plate 22 adds a shear-resistant surface B to the concrete structure 5, with a height of H2. Because H2 is greater than H1, the shear resistance of the shear surface B is greater than that of the shear surface A. For example, if the diameter of the anchor plate 1 is 150 mm, the height of H1 is 200 mm, the diameter of the annular wing is 220 mm, the height of H2 is 300 mm, and the concrete is C35, according to Formula 6.3.3 of the "Code for Design of Concrete Structures" GB50010-2010, the shear resistance of the impact surface A is 241 kN, while the shear resistance of the impact surface B is 538 kN. In some projects, to meet the shear resistance of the concrete structure 5, the thickness of the concrete structure 5 must be increased, significantly increasing the project cost. However, the plate-tube composite anchor plate with annular wing 22 of the present invention has two impact surfaces, A and B, which significantly improves the shear resistance of the concrete structure 5, reduces the height of the reinforced concrete structure 5, and saves a lot of project cost.

[0036] See also Figure 7 、 Figure 8 The utility model provides an anchor rod, comprising an anchor rod body 3, an anchor 4 and a plate-tube composite anchor plate, wherein the plate-tube composite anchor plate comprises an anchor pad 1 and a cylindrical member 2. The anchor rod body 3 is inserted into the rod body hole 11 of the anchor pad 1, and the anchor 4 is connected to the anchor rod body 3. Specifically, the anchor rod body 3 is inserted into the connection hole 41 of the anchor 4 and connected to the anchor 4. The anchor 4 anchors the anchor rod body 3 on the anchor pad 1. Specifically, the anchor 4 is pressed and fixed on the anchor pad 1 by the working tension of the anchor rod body 3, and the anchor rod body 3 is locked on the anchor pad 1 at the same time. The specific construction method is to first insert the anchor rod body 3 into the rod body hole 11 of the anchor pad 1 and expose the end of the anchor rod body 3, and then embed the plate-tube composite anchor plate in the concrete structure 5. After the concrete structure 5 solidifies and reaches the design strength, the anchor 4 is put on the end of the anchor rod body 3 and connected and locked to the anchor pad.

[0037] See also Figure 3 、 Figure 5 and Figure 9The present invention provides another anchor rod, comprising an anchor rod body 3 and a plate-tube composite anchor plate. The plate-tube composite anchor plate comprises an anchor plate 1, a cylindrical member 2, and an anchor 4. The anchor 4 is fixed to the anchor plate 1 by welding, specifically, using a weld 9 to integrally weld the anchor 4 to the anchor plate 1. The anchor rod body 3 is inserted through a rod hole 11 in the anchor plate 1 and connected to the anchor 4. Specifically, it is connected to the anchor rod body 3 through a connecting hole 41 in the anchor 4, thereby locking the anchor rod body 3 to the anchor plate 1.

[0038] In another embodiment, Figure 7 、 Figure 8 、 Figure 9 The cylindrical member 2 shown may also be filled with a filler 6 to seal the gaps between the anchor 4, the anchor plate 1 and the anchor rod body 3 to prevent ground water from seeping through these gaps. The filler 6 may be made of concrete, asphalt or grease.
