Description

Technical Field

[0001] This utility model relates to the field of building beam and column accessories, and in particular to a building beam and column reinforcement structure. Background Technology

[0002] Building beams and columns are the core components of a building structure that bear the load. In modern buildings, beams and columns can be divided into concrete structures, steel structures, and wood structures. In prefabricated concrete buildings, steel reinforcement structures are used to protect the connection between columns and beams in order to further improve the stability of the building.

[0003] Existing reinforcement structures are generally bolt-fixed rigid designs, with the overall structure forming a triangle to support beams and columns. However, due to the different specifications of beams and columns, different specifications of reinforcement components need to be adapted to different installation requirements. At the same time, beams and columns will experience slight vibrations during actual use, causing the bolt connections of the simple reinforcement components to loosen, making it difficult to tighten and protect them, which has certain limitations. Utility Model Content

[0004] In view of the problems existing in the above-mentioned building beam and column reinforcement structures, this utility model is proposed.

[0005] Therefore, the problem to be solved by this utility model is that the reinforcement structure in the prior art needs to be adapted to different specifications of reinforcement components for different installation requirements. At the same time, the beams and columns will experience slight vibrations during use, which will cause the bolt connections of the simple reinforcement components to loosen.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a building beam and column reinforcement structure, comprising, A prefabricated column, wherein a prefabricated crossbeam is fixed to the top of the prefabricated column; and... The reinforcement component, mounted on the prefabricated column, includes a first fixing hoop fitted onto the prefabricated column, a second fixing hoop fitted onto the prefabricated crossbeam, an anti-detachment component installed between the first fixing hoop and the second fixing hoop, a first movable rod rotatably connected to the first fixing hoop, a second movable rod slidably connected inside the first movable rod, a locking component on both sides of the first movable rod, and a positioning component on both the first fixing hoop and the second fixing hoop.

[0008] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, the first movable rod has a storage groove and is slidably connected to the second movable rod, and one end of the second movable rod is rotatably connected to the second fixing hoop.

[0009] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, a spring is fixed inside the storage groove, and the other end of the spring is fixed to the second movable rod.

[0010] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, the clamping component includes a fixing frame fixed to the surface of the first movable rod, a clamping block rotatably connected to the fixing frame, torsion springs fixed on both sides of the clamping block, and the other end of the torsion springs fixed to the fixing frame.

[0011] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, the first movable rod is provided with an auxiliary groove, and the second movable rod is provided with a locking groove.

[0012] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, the auxiliary groove and the locking block are slidably connected, as are the locking groove and the locking block.

[0013] As a preferred embodiment of the building beam and column reinforcement structure of this utility model, the first movable rod is fixed with protective shells on both sides, and the protective shells are provided with rectangular grooves. The protective shells are located outside the fixed frame, and the inner diameter of the rectangular grooves is smaller than the width of the locking block.

[0016] The beneficial effects of this utility model are as follows: by setting up the reinforcement components, the connection between the prefabricated column and the prefabricated beam can be reinforced and protected, forming a triangular stable protection. When the prefabricated column and the prefabricated beam vibrate and move relative to each other, the anti-detachment component is used to lock them in one direction.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a building beam and column reinforcement structure, which includes a prefabricated column 1, a prefabricated beam 2, and a reinforcement component 3. By setting the reinforcement component 3, the connection between the prefabricated column 1 and the prefabricated beam 2 can be reinforced and protected to form a triangular stable protection. When the prefabricated column 1 and the prefabricated beam 2 vibrate and move relative to each other, it can be unidirectionally locked to effectively improve the structural reinforcement stability. It is well applicable to vibration scenarios of prefabricated concrete beams and columns in building engineering.

[0029] Specifically, there is a prefabricated column 1, and a prefabricated crossbeam 2 is fixed to the top of the prefabricated column 1.

[0030] The prefabricated column 1 is a vertical load-bearing component, mainly bearing the axial pressure (vertical load) transmitted by the prefabricated beam 2. At the same time, it bears bending moment and shear force under horizontal loads (earthquake, wind), and finally transfers all loads to the foundation. The prefabricated beam 2 is the main load-bearing component in the horizontal direction, bearing vertical loads (such as self-weight, floor / roof loads, live loads), and transferring the loads to the prefabricated column 1 or the support. At the same time, under horizontal loads (such as earthquake, wind loads), it works with the prefabricated column 1 to resist lateral forces. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0031] Under wind loads—strong winds and gusts—the impact on the structure is “pulsating” (wind pressure changes irregularly over time), which will generate vertical or horizontal thrust on the horizontal prefabricated beam 2 and lateral force on the prefabricated column 1, causing periodic vibrations. High-rise buildings and large-span factory buildings are more sensitive to wind-induced vibrations.

[0032] Mechanical and dynamic loads: In industrial plants, the operation of machines (such as presses and motors) will generate periodic vertical or horizontal vibrations, which are transmitted to the prefabricated beams 2 and prefabricated columns 1 through the floor slab.

[0033] When the connection nodes (bolts) between the prefabricated column 1 and the prefabricated beam 2 are loose, or the components are not installed evenly, it will lead to uneven load transfer and generate "self-excited vibration" during normal use (such as high-frequency vibration caused by friction or collision between components after the bolts are loose).

[0034] Specifically, the reinforcement component 3 is installed on the prefabricated column 1, including a first fixing hoop 31 sleeved on the prefabricated column 1, a second fixing hoop 32 sleeved on the prefabricated crossbeam 2, an anti-detachment component 33 installed between the first fixing hoop 31 and the second fixing hoop 32, including a first movable rod 33-1 rotatably connected to the first fixing hoop 31, a second movable rod 33-2 slidably connected inside the first movable rod 33-1, a clamping component 33-3 on both sides of the first movable rod 33-1, and a positioning component 34 on both the first fixing hoop 31 and the second fixing hoop 32.

[0035] The anti-detachment component 33 can not only provide one-way locking protection when the distance between the first fixing hoop 31 and the second fixing hoop 32 changes, but also gradually lock when the distance decreases, greatly improving the overall structural stability.

[0036] Example 2 Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, there are two first fixing hoops 31 and two second fixing hoops 32, and fasteners 35 are provided between the two first fixing hoops 31 and between the two second fixing hoops 32.

[0038] Fastener 35 includes fastening bolts, fastening nuts, and spring washers. The three are installed using conventional methods in the prior art. Fastener 35 uses M16 high-strength bolts (8.8 grade), and the matching spring washers are made of 65Mn material. The preload torque is 45-50 N·m, ensuring that the clamping force of the two fixing hoops is ≥50kN. It can lock the two first fixing hoops 31 and the two second fixing hoops 32 to ensure the installation stability between the first fixing hoops 31 and the prefabricated column 1, and between the second fixing hoops 32 and the prefabricated beam 2.

[0039] The first movable rod 33-1 has a storage groove 33-11 inside, and is slidably connected to the second movable rod 33-2. One end of the second movable rod 33-2 is rotatably connected to the second fixed hoop 32.

[0040] A spring 33-12 is fixed inside the storage slot 33-11, and the other end of the spring 33-12 is fixed to the second movable rod 33-2.

[0041] The storage slot 33-11 provides storage space for the second movable rod 33-2 and the spring 33-12, and the spring 33-12 provides elastic tension to the second movable rod 33-2, as shown in the attached diagram. Figure 4As shown, in this state, the spring 33-12 provides the second movable rod 33-2 with the pulling force to slide into the storage groove 33-11. With this design, when the distance between the first fixed clamp 31 and the second fixed clamp 32 decreases, the second movable rod 33-2 will automatically slide into the storage groove 33-11.

[0042] The mounting component 33-3 includes a fixing frame 33-31 fixed to the surface of the first movable rod 33-1. A locking block 33-32 is rotatably connected to the fixing frame 33-31. Torsion springs 33-33 are fixed on both sides of the locking block 33-32, and the other end of the torsion spring 33-33 is fixed to the fixing frame 33-31.

[0043] The first movable rod 33-1 has an auxiliary groove 33-13, and the second movable rod 33-2 has a slot 33-21.

[0044] The auxiliary slot 33-13 and the card block 33-32 are slidably connected, as are the card slot 33-21 and the card block 33-32.

[0045] The torsion spring 33-33 provides torque for the rotation of the locking block 33-32, so that one end of the torsion spring 33-33 is always placed in the locking slot 33-21. In this state, the torsion spring 33-33 still provides the locking block 33-32 with inward rotation torque, increasing the contact friction between the locking block 33-32 and the locking slot 33-21.

[0046] The first movable rod 33-1 is fixed with protective shells 33-4 on both sides. The protective shells 33-4 have rectangular grooves 33-41. The protective shells 33-4 are located outside the fixed frame 33-31. The inner diameter of the rectangular grooves 33-41 is smaller than the width of the locking block 33-32.

[0047] The locking mechanism, consisting of the locking blocks 33-32 and the slot 33-21, provides a one-way locking function, as shown in the attached diagram in the instruction manual. Figure 6 As shown, in this state, when the second movable rod 33-2 slides into the storage slot 33-11, the locking block 33-32 can be squeezed and rotated to open. When the second movable rod 33-2 wants to get out of the storage slot 33-11, the locking block 33-32 cannot rotate due to the restriction of the protective shell 33-4.

[0048] The auxiliary slots 33-13 can meet the motion space requirements of the card blocks 33-32.

[0049] The rectangular groove 33-41 can be used with a special pressure strip. When the pressure strip passes through the rectangular groove 33-41 and comes into contact with multiple locking blocks 33-32, it can simultaneously squeeze the multiple locking blocks 33-32 to rotate and open, which is convenient for the staff to adjust the initial position of the second movable rod 33-2.

[0050] The positioning component 34 includes several fixing rods 34-1. The fixing rods 34-1 are fixedly connected to the prefabricated column 1 and to the prefabricated crossbeam 2. A stop bar 34-2 is rotatably connected to the fixing rods 34-1 through a damping bearing.

[0051] Both the first fixing hoop 31 and the second fixing hoop 32 have through grooves 34-3, which are slidably connected to the stop bar 34-2.

[0052] With the through groove 34-3 and the stop bar 34-2, the first fixing hoop 31 and the second fixing hoop 32 can be flexibly disassembled when they are aligned. In the two staggered states, the first fixing hoop 31 and the second fixing hoop 32 cannot be detached at will, which frees the operator's hands and facilitates the overall installation process.

[0053] In use, drive the stop bar 34-2 to rotate and align it with the through groove 34-3. Then move the first fixing hoop 31 close to the assembled column 1 so that the stop bar 34-2 passes through the through groove 34-3 and is placed outside the first fixing hoop 31. Then drive the stop bar 34-2 to rotate 90 degrees and align it with the through groove 34-3. At this time, the first fixing hoop 31 is suspended, freeing the operator's hands. Repeat the above steps to install the first fixing hoop 31 on the other side, and then lock it with the fastener 35.

[0054] Similarly, when installing the second fixing hoop 32, the above steps can be repeated to fix the first fixing hoop 31 to the prefabricated column 1 and the second fixing hoop 32 to the prefabricated beam 2.

[0055] During the above process, based on the distance between the first fixing hoop 31 and the second fixing hoop 32, the second movable rod 33-2 is slidably inserted into the storage groove 33-11 at a suitable distance, and is unidirectionally locked with the cooperation of the slot 33-21 and the locking block 33-32. When there is an unexpected vibration between the prefabricated column 1 and the prefabricated beam 2, the distance between the first fixing hoop 31 and the second fixing hoop 32 decreases, and the second movable rod 33-2 gradually enters the storage groove 33-11. With the cooperation of the locking block 33-32, it can be inserted into the new slot 33-21 to achieve the purpose of fitting and locking, effectively improving the overall stability of the structure.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
