Description

Technical Field

[0001] This utility model relates to the field of anchoring components, specifically to a Y-type reinforced anchor rod. Background Technology

[0002] Reinforced anchor rods refer to anchor rods whose rod body is made of steel bars. Among them, anchor rods for anti-buoyancy anchor rods, foundation pit sidewall anchor rods, and slope sidewall anchor rods are usually reinforced with uniform cross-sections. This results in the anchor rod body having a uniform cross-section from the head (top, used to connect the basement floor slab or foundation pit) to the tail (bottom). However, the stress on the anchor rod body gradually increases from the bottom to the top. Using a uniform cross-section structure requires that the top dimension, where the maximum stress occurs, meets the design requirements, resulting in excessive redundant reinforcement at the bottom of the anchor rod, leading to significant steel waste and poor economic efficiency. Utility Model Content

[0003] To address the technical problem of wasted steel bars caused by existing anchor rods with uniform cross-section reinforcement, this utility model provides a Y-type reinforced anchor rod. Based on the stress conditions of each section of the anchor rod, the sections of the anchor rod are configured with a cross-section that is larger at the top and smaller at the bottom, which can significantly reduce the reinforcement length of the anchor rod, thereby reducing the amount of reinforcement material used and improving economic efficiency.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a Y-shaped reinforced anchor rod, comprising: an anchor rod segment with a connecting member at the upper end, the connecting member being used to connect an underground structure or a slope sidewall; and a reinforced segment connected to the lower end of the anchor rod segment; wherein, in the installed state, the reinforced segment is a Y-shaped structure.

[0006] In an optional embodiment of this application, the anchor bolt segment is provided in two vertical sections, and the lower ends of the two anchor bolt segments are respectively connected to the corresponding side of the upper end of the reinforcement segment.

[0007] In an optional embodiment of this application, the reinforcement section includes: vertical reinforcement, arranged vertically; and two diagonal connecting bars, the lower end of each diagonal connecting bar being connected to the upper end of the vertical reinforcement, and the upper end being connected to the lower end of the corresponding anchor bar section, to ensure that the reinforcement section is a Y-shaped structure in the installation state; wherein, in the installation state, the two diagonal connecting bars are symmetrically arranged with respect to the vertical reinforcement.

[0008] In an optional embodiment of this application, in the installed state, the included angle between the length directions of the two oblique connecting ribs is an acute angle or a right angle.

[0009] In an optional embodiment of this application, a horizontal brace is further included, wherein both ends of the horizontal brace in the length direction are respectively connected to the lower end of the corresponding anchor segment.

[0010] In an optional embodiment of this application, the horizontal support rod includes: a first support rod segment, one end of which is hinged to the lower end of the corresponding anchor rod segment; and a second support rod segment, one end of which is hinged to the other end of the first support rod segment and the other end of which is hinged to the lower end of the corresponding anchor rod segment; wherein, the lower end of the inclined connecting bar is hinged to the upper end of the vertical reinforcing bar and the upper end of which is hinged to the lower end of the corresponding anchor rod segment, and in the installed state, the first support rod segment and the second support rod segment are respectively perpendicular to the corresponding anchor rod segment.

[0011] In an optional embodiment of this application, a connector is provided in the middle of the cross brace, and the ends of the first brace segment and the second brace segment away from the anchor segment are both hinged to the connector.

[0012] In an optional embodiment of this application, the reinforcement section further includes a support rod, which is vertically disposed at the upper end of the vertical reinforcement, and the upper end of the support rod can be connected to the connector; wherein, when the support rod is connected to the connector, the length directions of the first support rod section and the second support rod section are both perpendicular to the length direction of the support rod.

[0013] In an optional embodiment of this application, the connector is a through-hole annular structure, and a limiting ring is provided at the upper end of the support rod; wherein, in the installed state, the upper end of the support rod is inserted into the inner hole of the connector, and the lower end of the connector abuts against the upper side of the limiting ring.

[0014] In an optional embodiment of this application, the connecting member is an L-shaped hook structure.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] 1. The Y-type reinforced anchor bolt provided by this utility model includes an anchor bolt section and a reinforcement section. The reinforcement section is connected to the lower end of the anchor bolt section. In the installed state, the reinforcement section has a Y-shaped structure. This makes the upper section of the anchor bolt, which bears a larger overall force, have a uniform cross-sectional shape, which is the same as that of the prior art, to ensure that the anchor bolt section can withstand sufficient compressive load. At the same time, the Y-shaped structure of the reinforcement section makes the lower end of the anchor bolt, which bears a smaller overall force, a single steel bar structure. Therefore, the reinforcement of a single anchor bolt does not need to be the same length as the anchor bolt hole, which can significantly reduce the reinforcement length of the anchor bolt, thereby reducing the amount of reinforcement material used and improving economic efficiency.

[0017] 2. The Y-type reinforced anchor provided by this utility model has the lower end of the anchor section connected to the upper end of the reinforcement section, and the reinforcement section has a Y-shaped structure, which allows multiple anchor sections to be connected to the reinforcement section as a whole. During construction and installation, the entire anchor needs to be installed into the anchor hole at once, without the need to install individual anchors multiple times. The construction is simple and can improve construction efficiency. Attached Figure Description

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Example 1

[0032] Combination Figure 1 This embodiment provides a Y-shaped reinforced anchor rod, including: an anchor rod section 10, with a connecting member 11 at the upper end, the connecting member 11 being used to connect the underground structure 20 or the slope sidewall; a reinforced section 30, connected to the lower end of the anchor rod section 10; wherein, in the installed state, the reinforced section 30 is a Y-shaped structure.

[0033] Generally speaking, the connecting member 11 is an L-shaped hook structure, which can be welded to the steel bars in the underground structure 20 or the slope sidewall during installation, so as to connect the anchor section 10 to the steel bars in the underground structure 20 or the slope sidewall.

[0034] It is understood that the anchor bolt segment 10 is vertically arranged in two sections, and the lower ends of the two anchor bolt segments 10 are respectively connected to the corresponding side of the upper end of the reinforcement segment 30, so as to ensure that the anchor bolt segment 10 and the reinforcement segment 30 can be set in a one-to-one correspondence.

[0035] Combination Figure 2 The reinforcement section 30 includes: vertical reinforcement 31, which is arranged vertically; and two diagonal connecting bars 32, the lower end of each diagonal connecting bar 32 being connected to the upper end of the vertical reinforcement 31, and the upper end being connected to the lower end of the corresponding anchor section 10, so as to ensure that the reinforcement section 30 is a Y-shaped structure in the installation state; wherein, in the installation state, the two diagonal connecting bars 32 are symmetrically arranged about the vertical reinforcement 31, thereby ensuring that the two anchor sections 10 are subjected to balanced forces.

[0036] It should be noted that the included angle between the two inclined connecting bars 32 along their length is an acute angle or a right angle, so that the lateral component of the tensile force exerted by the anchor section 10 on the reinforcement section is within a controllable range.

[0037] In summary, the Y-shaped reinforced anchor provided in this embodiment includes an anchor section 10 and a reinforcement section 30. The reinforcement section 30 is connected to the lower end of the anchor section 10, and in the installed state, the reinforcement section 30 has a Y-shaped structure. This makes the upper section of the anchor with greater overall stress have a uniform cross-sectional shape, which is the same as that of the prior art, to ensure that the anchor section 10 can withstand sufficient compressive load. At the same time, the Y-shaped structure of the reinforcement section 30 makes the lower end of the anchor with less overall stress a single steel bar structure. Therefore, the reinforcement of a single anchor does not need to be the same length as the anchor hole 50, which can significantly reduce the reinforcement length of the anchor.

[0038] In other words, this embodiment configures the anchor rod segments with a cross-section that is larger at the top and smaller at the bottom according to the stress conditions of each segment of the anchor rod. This allows for variable area configuration based on the principle of gradual stress change in the anchor rod, which can significantly reduce the length of the anchor rod reinforcement, thereby reducing the amount of reinforcement material used and improving economic efficiency.

[0039] In addition, since the lower end of the anchor bolt section 10 is connected to the upper end of the reinforcement section 30, and the reinforcement section 30 has a Y-shaped structure, multiple anchor bolt sections 10 and reinforcement section 30 can be connected into a whole. During construction and installation, the entire anchor bolt only needs to be installed into the anchor bolt hole 50 at once, without the need to install individual anchor bolts multiple times. This simplifies construction and improves construction efficiency.

[0040] Example 2

[0041] Combination Figure 2 This embodiment provides a Y-type reinforced anchor rod. Based on embodiment 1, this embodiment also includes a horizontal brace 40. The two ends of the horizontal brace 40 in the length direction are respectively connected to the lower end of the corresponding anchor rod segment 10, so as to provide lateral support to the lower end of the two anchor rod segments 10 through the horizontal brace 40, thereby avoiding the damage to the filling concrete when the lateral component of the tensile force of the anchor rod segment 10 acting on the reinforced segment is too large.

[0042] Example 3

[0043] Combination Figure 3 This embodiment provides a Y-type reinforced anchor rod. Based on embodiment 2, the horizontal support rod 40 includes: a first support rod segment 41, one end of which is hinged to the lower end of the corresponding anchor rod segment 10; a second support rod segment 42, one end of which is hinged to the other end of the first support rod segment 41, and the other end of which is hinged to the lower end of the corresponding anchor rod segment 10; wherein, the lower end of the oblique connecting bar 32 is hinged to the upper end of the vertical reinforcement 31, and the upper end is hinged to the lower end of the corresponding anchor rod segment 10. In the installation state, the first support rod segment 41 and the second support rod segment 42 are respectively perpendicular to the corresponding anchor rod segment 10, so that the two anchor rod segments 10 can be brought together for storage, reducing the transportation size of the entire anchor rod, and facilitating the batch transportation of the entire anchor rod to the construction site for direct installation after prefabrication in the workshop.

[0044] Combination Figure 4 In this embodiment, a connector 43 is provided in the middle of the cross brace 40. The ends of the first support rod segment 41 and the second support rod segment 42 away from the anchor rod segment are both hinged to the connector 43 to facilitate the connection of the first support rod segment 41 and the second support rod segment 42.

[0045] Based on this, the reinforcement section 30 also includes a support rod 33, which is vertically arranged at the upper end of the vertical reinforcement 31, and the upper end of the support rod 33 can be connected to the connector 43; wherein, when the support rod 33 is connected to the connector 43, the length directions of the first support rod section 41 and the second support rod section 42 are both perpendicular to the length direction of the support rod 33, so that the support crossbar remains perpendicular to the anchor section 10 in the installation state.

[0046] Specifically, the connector 43 is a through-hole annular structure, and the upper end of the support rod 33 is provided with a limiting ring 34; wherein, in the installed state, the upper end of the support rod 33 is inserted into the inner hole of the connector 43, and the lower end of the connector 43 abuts against the upper side of the limiting ring 34, so as to ensure that the support crossbar remains perpendicular to the anchor rod section 10 in the installed state.

[0047] It should be noted that both the anchor bolt section 10 and the reinforcement section 30 are made of high-strength threaded steel to ensure sufficient adhesion between the anchor bolt and the concrete. Additionally, at the lower end of the anchor bolt section 10, connecting lugs are welded to the ends of the vertical reinforcement 31, the diagonal connecting reinforcement 32, and the support rod 33, facilitating the hinge connection of these components via pins for mass prefabrication.

[0048] During construction, the vertical reinforcement 31 is inserted into the anchor bolt hole 50, and then the two anchor bolt sections 10 are pressed down simultaneously until the pressing resistance increases. At this time, the connector 43 is sleeved on the upper end of the support rod 33, and the length directions of the first support rod section 41 and the second support rod section 42 are both perpendicular to the length direction of the support rod 33. Finally, concrete is poured. After the poured concrete sets, the first support rod section 41 and the second support rod section 42 remain perpendicular to the anchor bolt section 10, so that the horizontal support rod 40 can provide lateral support to the lower end of the two anchor bolt sections 10, thereby preventing the lateral component of the tension force of the anchor bolt section 10 acting on the reinforcement section from being too large and crushing the filling concrete.

[0049] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
