Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a post-installed anchor for building beam-column joints. Background Technology
[0002] In the construction of the intersection of steel structure and reinforced concrete, a fixed connection between the two is required to ensure stable anchorage points for the steel structure. This includes using construction methods such as post-installed anchors and reserved steel embedded parts as the base of the steel structure. The steel structure base is the only component that bears the vertical and horizontal loads of all steel components, and its quality and accuracy are crucial to the safety and stability of the entire steel structure. However, when reserving steel embedded parts are installed, they are tied or welded to the reinforcing bars. After acceptance, when the carpenter seals the formwork, they may accidentally push against them, causing them to shift. Alternatively, during concrete pouring, the weight of the concrete or the action of the vibrating pump may cause the embedded parts to shift horizontally and vertically. As a result, during the subsequent installation of steel columns, due to the deviation of the embedded parts, it is necessary to add post-installed anchors at the location. However, beam-column joints are often locations with densely arranged reinforcing bars, and post-installed embedded parts may not be able to anchor properly due to obstruction by the reinforcing bars. Utility Model Content
[0003] The purpose of this invention is to provide a post-installed anchor for building beam-column joints to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a post-installed anchor for building beam-column joints, comprising an anchoring component, a positioning component, and a steel column transition node plate, wherein the anchoring component is disposed at the bottom of the steel column transition node plate and is used to fix the position of the steel column transition node plate;
[0005] The anchoring assembly includes a first steel plate, and a threaded rod for fixing the position of the first steel plate is symmetrically fixedly connected to the bottom center of the first steel plate. A second steel plate is provided at the bottom of the threaded rod, and the positioning assembly is used to fix the position of the second steel plate and the threaded rod.
[0006] Preferably, the second steel plate has multiple through holes symmetrically opened in the center of its middle section, and the threaded rod is inserted and connected inside the through holes.
[0007] Preferably, the positioning component includes a nut disposed at the bottom of the second steel plate, the nut being threaded onto the bottom of the second steel plate.
[0008] Preferably, a washer is provided on the side of the positioning component opposite to the nut, the horizontal cross-section of the washer is set as an annular shape, and the washer is sleeved on the bottom of the threaded rod.
[0009] Preferably, the steel column transition node plate is fixedly connected to the top of the first steel plate, and the shape of the steel column transition node plate is set as a flange.
[0010] Preferably, one side of the second steel plate has a fitting groove adapted to the outer wall of the building column.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] This utility model, through the design of a first steel plate, a second steel plate, a threaded rod, and a fixing component, allows for the drilling of holes in the concrete slab, avoiding the beam-column connection, during use. The threaded rod of the first steel plate is then passed through the holes in the concrete slab sequentially, and the end of the threaded rod away from the first steel plate is fixed to the second steel plate using the fixing component, thereby fixing the position of the first steel plate. The steel column transition node plate is then welded to the first steel plate, eliminating the need to drill holes at the beam-column joint and insert post-embedded parts when fixing the steel column transition node plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-6 The diagram shows a post-installed anchor for a building beam-column joint, comprising an anchoring component 1, a positioning component 2, and a steel column transition node plate 3. The anchoring component 1 is located at the bottom of the steel column transition node plate 3 and is used to fix the position of the steel column transition node plate 3. The anchoring component 1 includes a first steel plate 101, and a threaded rod 103 for fixing the position of the first steel plate 101 is symmetrically fixedly connected to the bottom center of the first steel plate 101. A second steel plate 102 is provided at the bottom of the threaded rod 103. The positioning component 2 is used to fix the position of the second steel plate 102 and the threaded rod 103. A plurality of through holes 4 are symmetrically opened in the center of the middle of the second steel plate 102.
[0022] It should be noted that when the threaded rod 103 is fixed to the first steel plate 101, a positioning groove is first opened at the bottom end of the first steel plate 101, and then the top end of the threaded rod 103 is inserted into the positioning groove and fixed inside the positioning groove by welding.
[0023] Furthermore, after the concrete beam and concrete slab are poured, holes for the threaded rod 103 to pass through are pre-drilled in the concrete slab. According to the position of the hole in the concrete slab, a positioning groove is opened in the corresponding first steel plate 101 and a through hole 4 is opened in the second steel plate 102, so that the positioning groove at the bottom of the first steel plate 101, the hole in the concrete slab, and the through hole 4 on the second steel plate 102 are aligned in a straight line. After completion, the position is measured and checked to ensure it is correct. The first steel plate 101 is laid flat on the concrete slab, and the threaded rod 103 is directly welded to the first steel plate 101. The threaded rod 103 is then inserted into the hole in the concrete slab, and the second steel plate 102 is fitted onto the bottom of the threaded rod 103 through the through hole 4.
[0024] Specifically, the threaded rod 103 is inserted into the through hole 4. The positioning component 2 includes a nut 202 located at the bottom of the second steel plate 102. The nut 202 is threaded onto the bottom of the second steel plate 102. A washer 201 is provided on the side of the positioning component 2 opposite to the nut 202. The horizontal cross-section of the washer 201 is annular. The washer 201 is fitted onto the bottom of the threaded rod 103.
[0025] It should be noted that when the position of the first steel plate 101 needs to be fixed, the nut 202 is threaded onto the bottom of the threaded rod 103. The nut 202 is used to pull the threaded rod 103 downward, thereby fixing the position of the first steel plate 101. The washer 201 is placed between the nut 202 and the second steel plate 102. The washer 201 helps to evenly distribute the pressure, prevent loosening or deformation, thereby enhancing the stability and durability of the connection and preventing the nut 202 from loosening.
[0026] Specifically, the steel column transition node plate 3 is fixedly connected to the top of the first steel plate 101, and the shape of the steel column transition node plate 3 is set as a flange.
[0027] It should be noted that the steel column conversion node plate 3 is fixed to the top of the first steel plate 101 by welding.
[0028] Specifically, a fitting groove 5 adapted to the outer wall of the building column is provided on one side of the second steel plate 102.
[0029] It should be noted that the fitting groove 5 is designed according to the shape of the building's columns, so that the second steel plate 102 is not limited to the location of the rebar at rectangular beam-column joints, ring beam-column joints, irregular beam-column joints, etc. When the second steel plate 102 is fitted onto the bottom of the threaded rod 103 through the through hole 4, the top of the second steel plate 102 fits into the bottom of the concrete slab, and the two sides of the second steel plate 102 fit into the two adjacent concrete beams respectively. It also fits into the column through the fitting groove 5. The second steel plate 102 is restricted by the concrete beams, concrete slab, and column.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
