Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete beam-column structure technology, specifically a reinforced concrete beam-column structure. Background Technology

[0002] Reinforced concrete beam-column structures are structural systems composed of beams and columns, widely used in various buildings. The main function of a beam-column structure is to support the floor slab and its own weight and loads, transferring them to the columns and then to the foundation. This includes multi-story and high-rise buildings, industrial plants, etc. Due to its simple structure and convenient construction, it is suitable for various building requirements. Reinforced concrete beam-column structures have the following characteristics:

[0003] 1. Lightweight, high rigidity, and high strength: The main materials of beam-column structures are steel bars and concrete, which have high strength and rigidity and can withstand large loads;

[0004] 2. Easy to construct and simple in structure: Due to the relatively simple connection method of beams and columns, the construction process is relatively convenient.

[0005] During the construction of reinforced concrete beams and columns, pre-embedded holes are first opened at the outer ends of the walls and columns, and pre-embedded rods are inserted. In order to enhance the stability of the connection between the pre-embedded rods and the pre-embedded holes, chemical anchors are inserted into the pre-embedded holes in advance. The pre-embedded rods are fixed in the pre-embedded holes by the adhesiveness of the chemical anchors. However, when the main structure is subjected to vibration, the beams bend and cause the pre-embedded rods to shake. After the pre-embedded rods shake for a long time, the pre-embedded rods and chemical anchors loosen. At this time, the pre-embedded rods are easy to fall out of the pre-embedded holes. At the same time, the shaking pre-embedded rods are quite damaging to the walls and columns.

[0006] Therefore, this utility model provides a reinforced concrete beam-column structure to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a reinforced concrete beam-column structure that solves the aforementioned problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a reinforced concrete beam-column structure, comprising an embedded rod, a T-shaped plate being snapped onto the outer end of the embedded rod, a connecting thread being provided on the outer end of the embedded rod, a fixing nut being threaded onto the outer end of the connecting thread, a limiting component being provided on the outer end of the embedded rod, the limiting component comprising symmetrically opened grooves on the outer end of the embedded rod, a sliding plate being slidably connected inside the grooves, rotating rods being symmetrically rotatably connected to both sides of the sliding plate, a connecting plate being rotatably connected between the two rotating rods, a limiting plate being movably connected to the outer end of the connecting plate, a plug-in plate being snapped onto the outer end of the T-shaped plate, and a crossbeam body being fixedly connected to the outer end of the plug-in plate.

[0009] Preferably, there are four embedded rods, and a limiting thread is provided at the center of each embedded rod. The limiting assembly also includes limiting rods that are symmetrically rotatably connected to both ends of the embedded rod.

[0012] Preferably, the T-shaped plate and the plug-in plate have assembly holes at their outer ends, and a snap-fit ​​bolt is snapped into the assembly hole. The outer end of the snap-fit ​​bolt is symmetrically threaded with a snap-fit ​​nut.

[0014] Beneficial effects

[0015] This utility model provides a reinforced concrete beam-column structure. Compared with the prior art, it has the following advantages:

[0016] Beneficial effects:

[0017] In this reinforced concrete beam-column structure, by rotating the limiting rods inside both ends of the embedded rod, and simultaneously because the outer end of the embedded rod has two sets of opposing threads, the two sets of sliding plates move in opposite directions inside the embedded rod. During the movement of the sliding plates, the rotating rod drives the connecting plate and the limiting plate at its outer end to unfold towards the outer end of the embedded rod. At this time, the limiting plate engages with the inner wall of the embedded hole, and at the same time, the limiting plate is fixed and limited with the chemical anchor, which enhances the stability of the embedded rod inside the embedded hole, prevents the embedded rod from shaking, and prevents the connection between the embedded rod and the embedded hole from loosening, thus preventing the embedded rod from detaching from the chemical anchor and the inside of the embedded hole.

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-4A reinforced concrete beam-column structure includes an embedded rod 1, with a T-shaped plate 2 snapped onto the outer end of the embedded rod 1. The outer end of the embedded rod 1 is provided with a connecting thread, and a fixing nut 3 is threaded onto the outer end of the connecting thread. A limiting component 4 is provided at the outer end of the embedded rod 1. The limiting component 4 includes a sliding groove 401 symmetrically opened at the outer end of the embedded rod 1. A sliding plate 402 is slidably connected inside the sliding groove 401. Rotating rods 403 are symmetrically rotatably connected to both sides of the sliding plate 402. A connecting plate 404 is rotatably connected between the two rotating rods 403. A limiting plate 405 is movably connected to the outer end of the connecting plate 404. A plug-in plate 5 is snapped onto the outer end of the T-shaped plate 2. A crossbeam body 6 is fixedly connected to the outer end of the plug-in plate 5. The purpose of this setup is to first create a pre-embedded hole at the outer end of the wall column before installing the main beam 6. The pre-embedded hole penetrates the main beam 6. Then, a chemical anchor is inserted into the pre-embedded hole. An electric drill is used to penetrate the pre-embedded rod 1 through the pre-embedded hole inside the main beam 6. During the process of engaging the pre-embedded rod 1, the front end of the pre-embedded rod 1 breaks the chemical anchor, causing the chemical anchor to form an adhesive layer with the pre-embedded rod 1. The limiting rods 406 inside both sides of the pre-embedded rod 1 are then quickly rotated. Since the outer end of the limiting rod 406 has two sets of opposing threads, the sliding plate 402 slides in opposite directions in the sliding groove 401 at the outer end of the pre-embedded rod 1. The two sets of sliding plates 402 sliding in opposite directions drive the rotating rod 4. When the connecting plate 404 of 03 is unfolded, the limiting plate 405 at its outer end engages with the adhesive layer formed by the chemical anchor. Alternatively, the pre-embedded rod 1 can be fixed between the inner walls of the pre-embedded hole by the limiting plate 405 first, and then cement can be injected into the pre-embedded hole to seal it. At the same time, the outer end of the limiting plate 405 is provided with a groove to increase the stability of the engagement between the limiting plate 405 and the chemical anchor or the inner wall of the pre-embedded hole, reduce the vibration of the wall column and the amplitude of the pre-embedded rod 1 shaking inside the pre-embedded hole, thereby preventing the pre-embedded rod 1 from falling out of the pre-embedded hole. It also reduces the damage to the wall column caused by the pre-embedded rod 1 caused by the vibration bending of the main beam 6.

[0026] Four embedded rods 1 are provided, and a limiting thread is provided at the center of the embedded rod 1. The limiting assembly 4 also includes limiting rods 406 that are symmetrically rotatably connected to both ends of the embedded rod 1. The purpose of this arrangement is to enhance the stability of the connection between the T-shaped plate 2 and the wall column by setting four embedded rods 1, and the limiting thread also enhances the stability of the engagement between the embedded rod 1 and the embedded hole.

[0027] The outer end of the limiting rod 406 is symmetrically threaded, with two sets of threads arranged in opposite directions. The threads at the outer end of the limiting rod 406 are threadedly connected to the slide plate 402. The purpose of this arrangement is that the two sets of threads arranged in opposite directions allow the outer ends of the two sets of slide plates 402 and the embedded rods 1 to slide in opposite directions during the rotation of the limiting rod 406.

[0028] The two ends of the embedded rod 1 are symmetrically connected with sealing sleeves 7, and the cross-section of the sealing sleeves 7 is T-shaped. The purpose of this setting is that the symmetrically threaded sealing sleeves 7 can seal the embedded hole, making it easy to pour cement into the embedded hole to seal it. At the same time, the sealing sleeves 7 can protect the two ends of the embedded hole and reduce the damage to the wall column caused by the shaking of the embedded rod 1.

[0029] Example 2:

[0030] Please see Figure 1-4 This embodiment provides a reinforced concrete beam-column structure technical solution based on Embodiment 1: Assembly holes are provided at the outer ends of the T-shaped plate 2 and the plug-in plate 5. A clamping bolt 8 is inserted into the interior of the assembly hole, and a clamping nut 9 is symmetrically threaded onto the outer end of the clamping bolt 8. The purpose of this arrangement is to allow the plug-in plate 5, which is fixed to the main beam 6, to be inserted into the outer end of the T-shaped plate 2 during the assembly of the T-shaped plate 2 and the plug-in plate 5, thereby positioning the assembly holes at the outer ends of the T-shaped plate 2 and the plug-in plate 5, and fixing the connection between the T-shaped plate 2 and the plug-in plate 5 using the clamping bolt 8 and the clamping nut 9.

[0031] There are four sets of snap-fit ​​bolts 8 arranged in a rectangular pattern. The purpose of this arrangement is to enhance the stability of the connection between the T-shaped plate 2 and the plug-in plate 5.
