Description

Technical Field

[0001] This utility model relates to the field of reinforcement technology, and in particular to a reinforcement structure for concrete beams. Background Technology

[0002] The main methods for strengthening concrete beams include increasing the cross-section, externally bonding steel sections, bonding steel plates, bonding fiber cloth, applying prestress, and adding supports.

[0003] In existing technologies, the drilling and grouting method is commonly used for concrete beams. This involves excavating and filling the concrete inside the beam, and then using grout to reinforce the concrete with formwork. However, this method is costly and not suitable for large-scale or widespread implementation. Furthermore, the reinforced frame structure of the increased cross-section reinforcement method does not have high strength, which can easily lead to the same structural strength as the subsequent spray coating. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reinforced concrete beam structure with advantages such as high structural strength and easy frame installation, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a reinforced concrete beam structure, comprising a beam body, wherein vertical ribs are uniformly arranged in a linear array around the beam body, and ring ribs are uniformly arranged in a linear array on one side of the vertical ribs on the outer ring of the beam body, wherein steel wire is wound at the contact point between the vertical ribs and the ring ribs, wherein through holes A and B are symmetrically arranged in a linear array inside the beam body, wherein through holes A and B are located on different surfaces and are staggered, wherein reinforcing ribs are provided inside through holes A and B, wherein horizontal plates are provided on the four sides of the beam body, wherein spacers are symmetrically arranged between the horizontal plates and the beam body, and chemical bolts are provided between the interior of the beam body and the interior of the horizontal plates.

[0006] With the above structural setup, when using this device to reinforce the beam, the strength of the foundation frame can be increased, and the reinforcing bars will increase the structural strength of the beam. Since the reinforcing bar array is installed inside the beam, the structural strength of the internal part of the beam is improved, thus playing a reinforcing role. The setting of the horizontal plate increases the structural strength of the foundation frame. After spraying high ductility concrete, the beam is reinforced as a whole, achieving a high strength effect after reinforcement.

[0007] Preferably, the horizontal plate is located on the side of the vertical reinforcement away from the beam. The horizontal plate includes side plate A and side plate B. Side plate A is located at both ends of the through hole A, and side plate B is located at both ends of the through hole B. Side plate A is located below the ring reinforcement, and side plate B is located above the ring reinforcement. An installation groove is formed in the middle of the surface of the horizontal plate, and ring retaining grooves are formed on both sides of the installation groove on the surface of the horizontal plate.

[0008] With the above structural design, the reinforcing bars and vertical bars are fixed by the horizontal plates, which improves the frame strength of the device. Chemical bolts are used to install inside the beam and the horizontal plates to ensure sufficient spacing between the frame and the beam.

[0009] Preferably, the horizontal plate is located at the end of the reinforcing rib, the mounting groove is at the same center as the reinforcing rib, the two ends of the reinforcing rib are provided with threaded grooves, the reinforcing rib is provided with a fixing head inside the mounting groove, the end of the fixing head is provided with a threaded post, and the threaded post and the threaded groove are threadedly matched.

[0010] By setting up the above structure and installing reinforcing bars between the cross plate and the beam using fixing heads, the structural strength of the beam is increased, thereby improving the structural strength of some internal structures of the beam.

[0011] Preferably, the spacer block has an arc groove on the side near the vertical rib, the arc groove is adapted to the shape of the vertical rib, and the vertical rib is located inside the arc groove of the spacer block.

[0012] With the above structural design, the spacer blocks are used to support the position between the beam and the vertical reinforcement. When the spacer blocks are used to limit the position of the vertical reinforcement and the horizontal plate, the overall strength of the structure is further improved.

[0013] Preferably, the surface of the beam has short holes on both sides of the through holes A and B, the chemical bolt is located inside the short holes, the shape of the chemical bolt is adapted to the shape of the short holes, and a nut is fixedly installed at the end of the chemical bolt. The nut is located inside the ring groove, and the outer ring of the nut is adapted to the shape of the ring groove.

[0014] With the above structural setup, chemical bolts are used to reinforce the connection between the reinforcing bars and the beam. When the reinforcing bars are installed alone, the support effect is poor. By installing chemical bolts on both sides of the reinforcing bars, they play an auxiliary role in reinforcing the reinforcing bars.

[0015] This utility model has the following advantages:

[0016] 1. This concrete beam reinforcement structure achieves stable reinforcement of the beam by setting up ring bars, reinforcing bars, and horizontal plates. The beam is provided with through holes and slots for installing chemical bolts on all four sides. Spacer blocks, vertical bars, and ring bars are installed around the beam. The vertical bars and ring bars are fixed with steel wire to form a basic frame. The reinforcing bars are inserted into the through holes A and B. Then, horizontal plates are installed at both ends of the reinforcing bars. Fixing heads are installed inside the installation slots to fix the ends of the reinforcing bars. After the horizontal plates compress the vertical bars inward, the vertical bars will not deform due to tensile force due to the support of the spacer blocks, thus achieving a stable reinforcement effect.

[0017] 2. This concrete beam reinforcement structure achieves auxiliary reinforcement by setting up spacer blocks, chemical bolts, and other structures. The groove for installing chemical bolts is filled with chemical tubes or reagent tubes. Then, the chemical bolts are inserted into the beam from inside the ring groove, so that the chemical bolts are fixed inside the beam by the substance inside the chemical tubes. Nuts are then used to fix the position of the chemical bolts. The cross plate is supported by the spacer blocks, and then the position is restricted by the reinforcing bars and chemical bolts, thus achieving the effect of auxiliary reinforcement.

[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] Please see Figures 1-2 A reinforced concrete beam structure includes a beam body 1. Vertical ribs 2 are arranged in a linear array around the beam body 1. Circular ribs 3 are arranged in a linear array on one side of the vertical ribs 2 around the outer edge of the beam body 1. Steel wire is wound around the contact points of the vertical ribs 2 and the circular ribs 3 to stabilize the connection between them. Through holes A and B are arranged in a linear symmetrical pattern inside the beam body 1. Through holes A and B are located on different surfaces and are staggered. Reinforcing ribs 4 are installed inside through holes A and B. Horizontal plates 5 are provided on all four sides of the beam body 1. Spacers 6 are symmetrically arranged between the horizontal plates 5 and the beam body 1. Chemical bolts 7 are installed between the interior of the beam body 1 and the interior of the horizontal plates 5.

[0025] When this device is used to reinforce beam 1, the strength of the foundation frame can be increased, and the reinforcing bars 4 will increase the structural strength of beam 1. Since the reinforcing bars 4 array is installed inside beam 1, the structural strength of the internal part of beam 1 is improved, thus playing a reinforcing role. The structural strength of the foundation frame is increased by setting the horizontal plate 5. After spraying high ductility concrete, beam 1 is reinforced as a whole, resulting in a high strength after reinforcement.

[0026] Please see Figures 1-4 The horizontal plate 5 is located on the side of the vertical reinforcement 2 away from the beam 1. The horizontal plate 5 includes side plate A and side plate B. Side plate A is located at both ends of the through hole A, and side plate B is located at both ends of the through hole B. Side plate A is located on the lower side of the ring reinforcement 3, and side plate B is located on the upper side of the ring reinforcement 3. An installation groove is provided in the middle of the surface of the horizontal plate 5, and ring grooves are provided on both sides of the installation groove on the surface of the horizontal plate 5.

[0027] The reinforcing bars 4 and vertical bars 2 are fixed by the horizontal plate 5 respectively, which improves the frame strength of the device. Chemical bolts 7 are installed inside the beam 1 and the horizontal plate 5 to ensure that there is a sufficient gap between the frame and the beam 1. This device will not affect the structural strength of the beam 1 itself after reinforcing the beam 1, and will only reinforce and fix the outside of the beam 1.

[0028] Please see Figures 1-4 The horizontal plate 5 is located at the end of the reinforcing rib 4. The mounting groove is the same as the axis center of the reinforcing rib 4. Threaded grooves are opened at both ends of the reinforcing rib 4. The reinforcing rib 4 is provided with a fixing head 41 inside the mounting groove. The end of the fixing head 41 is provided with a threaded post. The threads of the threaded post and the threaded groove are compatible.

[0029] By setting up reinforcing bars 4 and using fixing heads 41 to install reinforcing bars 4 between the horizontal plate 5 and the beam 1, the structural strength of the beam 1 is increased after the reinforcing bars 4 are installed inside the beam 1, thereby improving the structural strength of the internal part of the beam 1 and preventing cracking of the beam 1 from affecting the whole.

[0030] Please see Figures 1-4 An arc groove is provided on the side of the spacer block 6 near the vertical rib 2. The arc groove is adapted to the shape of the vertical rib 2, and the vertical rib 2 is located inside the arc groove of the spacer block 6.

[0031] Spacer 6 is used to support the position between beam 1 and vertical reinforcement 2. Due to the tension of reinforcing bar 4 and chemical bolt 7, the horizontal plate 5 may become fatigued over time. By using spacer 6 to limit the position of vertical reinforcement 2 and horizontal plate 5, the strength of the overall structure is further improved.

[0032] Please see Figures 1-4Short holes are provided on both sides of the perforation A and perforation B on the surface of beam 1. Chemical bolts 7 are located inside the short holes. The shape of chemical bolts 7 is adapted to the shape of the short holes. A nut 71 is fixedly installed at the end of chemical bolts 7. The nut 71 is located inside the ring groove. The shape of the outer ring of the nut 71 is adapted to the shape of the ring groove.

[0033] Chemical bolts 7 are used to reinforce the connection between the reinforcing bar 4 and the beam 1. After the reinforcing bar 4 is installed alone, the support effect is poor. By installing chemical bolts 7 on both sides of the reinforcing bar 4, it plays an auxiliary role in reinforcing the reinforcing bar 4, and at the same time further alleviates the fatigue of the cross plate 5, and has a certain reinforcement effect on the overall device.

[0034] Working principle: Through holes and slots for installing chemical bolts 7 are made around the four sides of beam 1. Spacer blocks 6, vertical reinforcement 2, and ring reinforcement 3 are installed around the four sides of beam 1. The vertical reinforcement 2 and ring reinforcement 3 are fixed with steel wire to form a basic frame. Reinforcing bars 4 are inserted into through holes A and B. Then, horizontal plates 5 are installed at both ends of the reinforcing bars 4. Fixing heads 41 are installed inside the installation slots to fix the ends of the reinforcing bars 4. After the horizontal plates 5 compress the vertical reinforcement 2 inwards, the vertical reinforcement 2 will not deform due to tensile force due to the support of the spacer blocks 6. The reinforcing bars 4 are then... After fixing, first fill the groove for installing the chemical bolt 7 with a chemical tube or reagent tube, then insert the chemical bolt 7 into the beam 1 from the ring groove, so that the chemical bolt 7 is fixed inside the beam 1 by the substance inside the chemical tube. Then use the nut 71 to fix the position of the chemical bolt 7, so that the horizontal plate 5 is supported by the spacer block 6, and then the position is restricted by the reinforcing rib 4 and the chemical bolt 7. Then spray high ductility concrete around the beam 1, so that the device is completely submerged. After the high ductility concrete layer solidifies, the beam 1 is reinforced.
