Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a structural beam reinforcement structure for building construction. Background Technology

[0002] In the field of building construction, structural beams play a crucial role in load-bearing and support. With increasing building height and diversified functions, higher demands are placed on the load-bearing capacity and stability of structural beams. Traditional structural beam designs are gradually revealing some shortcomings when facing complex loads and long-term use.

[0003] Existing structural beam reinforcement methods have significant limitations. On the one hand, the supports at both ends and the middle of the beam are not flexible enough and cannot be effectively adjusted according to different load distributions. This leads to localized stress concentration in the beam during actual use, causing structural deformation and affecting the safety and service life of the building. On the other hand, the stability and integrity of the structure need to be improved during beam reinforcement, and the lack of effective support and restraint measures makes it difficult to meet the high-quality and reliability requirements of modern buildings. Therefore, a structural beam reinforcement structure for building construction is proposed. Utility Model Content

[0025] To support the roof beam, the edge beam support structure 3 includes: a first threaded sleeve 30 and a first threaded rod 31. The first threaded sleeve 30 has an internal thread, and the first threaded rod 31 rotates inside the first threaded sleeve 30. There are two first threaded rods 31, located at opposite ends of the first threaded sleeve 30, and the first threaded rods 31 are threadedly connected to the first threaded sleeve 30; a first fixing plate 34, rotatably mounted on the end of the first threaded rod 31 away from the first threaded sleeve 30; a support 38, threaded onto the first threaded rod 31, used to support the simply supported beam 1; and a pair of clamps 39, mounted on both sides of the support 38 and the simply supported beam 1, used to fix the support 38 and the simply supported beam 1. The edge beam support structure 3 also includes: a pin groove 32, located on the side of the first threaded rod 31 away from the first fixing plate 34; and a pin block 33, which is inserted into the pin groove 32 during installation, with an interference fit between the pin block 33 and the pin groove 32. The side beam support structure 3 also includes: a first limiting head 35, which is fixedly connected to the first fixing plate 34. The first limiting head 35 is rotatably installed at the end of the first threaded rod 31 away from the first threaded sleeve 30. The first fixing plate 34 is rotatably connected to the first threaded rod 31 through the first limiting head 35; a first bolt 36 and a first nut 37, one end of the first bolt 36 is fixedly installed inside the beam column 6, and the other end passes through the first fixing plate 34. The first nut 37 is threaded onto the first bolt 36.

[0026] The support 38 consists of a threaded collar 380, a second threaded sleeve 381, a second threaded rod 382, ​​a second fixing plate 383, and a second limiting head 384. The threaded collar 380 has an internal thread and is threadedly mounted on the first threaded rod 31. The second threaded sleeve 381 is welded and fixed to the threaded collar 380, and has an internal thread inside. The second threaded rod 382 is threadedly mounted inside the second threaded sleeve 381. The second limiting head 384 is fixedly connected to the second fixing plate 383 and is rotatably mounted on the end of the second threaded rod 382 away from the second threaded sleeve 381. It is suspended below the beam by the support 38 to support it.

[0027] The clamp 39 consists of a pair of clamping plates 390, a rubber pad 391, a double-ended bolt 392, and a pair of second nuts 393. The rubber pad 391 is fixedly installed on the clamping plates 390. During installation, the two clamping plates 390 are respectively located above the simply supported beam 1 and below the second fixed plate 383, and the double-ended bolt 392 passes through the two clamping plates 390. The two second nuts 393 are respectively threaded on both ends of the double-ended bolt 392, and the simply supported beam 1 and the second fixed plate 383 are located between the two second nuts 393. The clamp 39 fixes the support 38 to the beam to prevent the support 38 from moving.

[0028] During construction, the simply supported beam 1 is first suspended between the two beams and columns 6. The end panels 5 on both sides of the beam and column 6 are aligned with one side of the beam and column 6. Holes are drilled in the beam and column 6 according to the hole positions on the end panels 5. The fifth bolt 8 is passed through the hole on the end panels 5 and fixedly installed in the beam and column 6. The fifth nut 7 is then threaded onto the fifth bolt 8. At this point, the simply supported beam 1 is installed. Before applying a load to the simply supported beam 1, the foundation support structure 2, the side beam support structure 3, and the middle beam support structure 4 are installed.

[0029] First, install the side beam support structure 3. Using a suspension tool or other support tool, suspend the first threaded sleeve 30 in the middle section below the simply supported beam 1. Rotate the first threaded rods 31 on both sides respectively. When the first threaded rods 31 rotate, they engage with the threads inside the first threaded sleeve 30, thereby allowing the first threaded rods 31 to extend and retract within the first threaded sleeve 30. Rotate the first threaded rods 31 on both sides until the first fixing plate 34 is in contact with one side of the beam-column 6. Drill holes in the beam-column 6 according to the holes on the first fixing plate 34, and pass the first bolts 36 through the first fixing plate 34 to fix them to the beam-column 6. Inside, screw the first nut 37 onto the first bolt 36 and tighten it. Now, both ends of the first threaded rod 31 are fixed to the beams 6 on both sides. Based on the load above the simply supported beam 1, determine the points where the simply supported beam 1 needs support at both ends. Rotate the support 38. When the support 38 rotates, it engages with the first threaded rod 31 through the threaded collar 380, thereby allowing the support 38 to move left and right on the first threaded rod 31. Move the support 38 to the appropriate position and ensure that the second threaded sleeve 381 is vertical. Rotate the second threaded rod 382 to engage the second threaded rod 31. Rod 382 extends from the second threaded sleeve 381 until the upper surface of the second fixing plate 383 abuts against the lower surface of the simply supported beam 1. At this point, clamp 39 can be installed. Two clamping plates 390 are placed on the simply supported beam 1 and the lower surface of the second fixing plate 383, respectively. During installation, rubber pads 391 should be in contact with the surfaces of the simply supported beam 1 and the second fixing plate 383. Double-ended bolts 392 are passed through the openings in the clamping plates 390, and second nuts 393 are screwed into both ends of the double-ended bolts 392. The two second nuts 393 are tightened respectively, so that the clamping plates 390 clamp the simply supported beam 1 and the second fixing plate 383. With plate 383 in place, the side beam support structure 3 is now installed. The side beam support structure 3 can support both ends of the simply supported beam 1 using the support 38. The relative position of the support 38 can be changed according to different load conditions on the simply supported beam 1, making it suitable for different load situations. When the load on the simply supported beam 1 is concentrated in the middle section of the simply supported beam 1, the support 38 can be placed near the middle section of the simply supported beam 1. When the load on the simply supported beam 1 is relatively uniform or the load is close to both ends of the simply supported beam 1, the support 38 can be placed near both ends of the simply supported beam 1.

[0030] Example 2: Refer to Figure 1-3 and Figure 7-8To support the middle section of the beam and prevent sagging, the middle beam support structure 4 includes: a fourth fixing plate 40, which is installed on the beam columns 6 on both sides and located on the same side of the beam column 6. Two fourth fixing plates 40 are installed symmetrically about the simply supported beam 1; a wire hole 41, which is opened on the fourth fixing plate 40; a steel cable 42, which is located on the same side and has both ends passing through the wire hole 41 of the fourth fixing plate 40 on both sides of the beam column 6; and a limiting block 43, which is fixedly welded to the steel cable. The beam 42 has two holes at both ends, each passing through a wire hole 41. Two eye bolts 44 and four nuts 45 are also present. The two eye bolts 44 are respectively hung on the steel cables 42 on both sides of the simply supported beam 1, with the eye bolts 44 located in the middle section of the simply supported beam 1. The two fourth nuts 45 are threaded onto the eye bolts 44. A steel plate 46 has two holes, through which it slides onto the eye bolts 44. During installation, the steel plate 46 is located between the simply supported beam 1 and the fourth nuts 45. The middle beam support structure 4 also includes: a third bolt 47 and a third nut 48. One end of the third bolt 47 is fixedly installed inside the beam column 6, and the other end passes through the end panel 5 and the fourth fixing plate 40. The third nut 48 is threaded onto the end of the third bolt 47 that passes through the end panel 5 and the fourth fixing plate 40.

[0031] To further prevent the middle section of the simply supported beam 1 from deflecting under stress, a middle beam support structure 4 is required to support the middle section of the simply supported beam 1. The fourth fixing plate 40 is installed on the end panel 5, and the fourth fixing plate 40 is fixed to the beam column 6 and the end panel 5 using the third bolt 47 and the third nut 48. The two ends of the steel cable 42 are passed through the wire hole 41 respectively, and the steel cable 42 is passed from one side of the fourth fixing plate 40 to above the fourth fixing plate 40. According to the position of the middle section of the wire hole 41, the steel cable 42 is appropriately stretched or loosened so that the position of the middle section of the steel cable 42 is flush with the lower surface of the simply supported beam 1. After determining the length of the steel cable 42, an upper limit block 43 is welded at the position where the steel cable 42 passes through the wire hole 41. The size of the upper limit block 43 is larger than the hole diameter of the fourth fixing plate 40, and the upper limit block 43 is used to limit the steel cable 42. On the other side of the simply supported beam 1, another steel cable 42 is installed in the same manner. After the two steel cables 42 are installed, eye bolts 44 are hung on the steel cables 42, and the eye bolts 44 are located in the middle section of the simply supported beam 1. The eye bolts 44 are bolts with a hook at one end and threads at the other end. The steel plate 46 is slidably installed on the two eye bolts 44, and the third nut 48 is screwed on and tightened until the upper surface of the steel plate 46 is flush with the lower surface of the simply supported beam 1. The working principle is: when there is a load on the middle section of the simply supported beam 1, the middle section of the simply supported beam 1 generates a downward force. Under the action of the steel cable 42, the steel plate 46 exerts a supporting reaction on the simply supported beam 1, thereby offsetting or reducing the force exerted on the middle section of the simply supported beam 1 by the load above the simply supported beam 1, thereby avoiding or delaying the downward deflection of the middle section of the simply supported beam 1. The remaining features are the same as in Embodiment 1.

[0032] Example 3: Refer to Figure 3 and Figure 9 To ensure greater stability during operation of the side beam support structure 3, the foundation support structure 2 includes: a support square steel 20 and a third fixing plate 23, with the third fixing plate 23 fixedly welded to the support square steel 20; a support head 21, which is fixedly welded to the end of the support square steel 20 away from the third fixing plate 23, with an arc-shaped groove 22 on the support head 21, and the support head 21 is installed below the first threaded rod 31 with the outer surface of the first threaded rod 31 in contact with the arc-shaped groove 22; a sixth bolt 24 and a sixth nut 25, with one end of the sixth bolt 24 fixedly installed inside the beam column 6 and the other end penetrating through the third fixing plate 23, and the sixth nut 25 threadedly installed on the end of the sixth bolt 24 that penetrates through the third fixing plate 23.

[0033] To make the side beam support structure 3 more stable, the foundation support structure 2 can be selectively installed to support the side beam support structure 3. The support square steel 20 is fixed to the beam column 6 by the third fixing plate 23 using the sixth bolt 24 and the sixth nut 25. The fixing method is the same as the bolt and nut fixing method to the beam column 6. The support head 21 needs to be pre-grooved and welded to the end of the support square steel 20 away from the third fixing plate 23. When fixing the third fixing plate 23, the position of the third fixing plate 23 on the beam column 6 should be adjusted according to the position of the support head 21. It should be ensured that after the third fixing plate 23 is fixed, the support head 21 is suspended below the first threaded rod 31 and the first threaded rod 31 is in contact with the arc groove 22. In this way, the support head 21 and the support square steel 20 support both ends of the first threaded rod 31, which further improves the stability of the side beam support structure 3 when it is supported. The remaining features are the same as in embodiment 1.

[0034] Working principle: During construction, the simply supported beam 1 is first suspended between the two beams and columns 6. The end panels 5 on both sides of the beam and column 6 are aligned with one side of the beam and column 6. According to the hole positions on the end panels 5, holes are drilled in the beam and column 6. The fifth bolt 8 is passed through the hole on the end panels 5 and fixedly installed in the beam and column 6. The fifth nut 7 is then threaded onto the fifth bolt 8. At this time, the simply supported beam 1 is installed. Before applying a load to the simply supported beam 1, the foundation support structure 2, the side beam support structure 3, and the middle beam support structure 4 are installed.

[0035] First, install the side beam support structure 3. Using a suspension tool or other support tool, suspend the first threaded sleeve 30 in the middle section below the simply supported beam 1. Rotate the first threaded rods 31 on both sides respectively. When the first threaded rods 31 rotate, they engage with the threads inside the first threaded sleeve 30, thereby allowing the first threaded rods 31 to extend and retract within the first threaded sleeve 30. Rotate the first threaded rods 31 on both sides until the first fixing plate 34 is in contact with one side of the beam-column 6. Drill holes in the beam-column 6 according to the holes on the first fixing plate 34, and pass the first bolts 36 through the first fixing plate 34 to fix them to the beam-column 6. Inside, screw the first nut 37 onto the first bolt 36 and tighten it. Now, both ends of the first threaded rod 31 are fixed to the beams 6 on both sides. Based on the load above the simply supported beam 1, determine the points where the simply supported beam 1 needs support at both ends. Rotate the support 38. When the support 38 rotates, it engages with the first threaded rod 31 through the threaded collar 380, thereby allowing the support 38 to move left and right on the first threaded rod 31. Move the support 38 to the appropriate position and ensure that the second threaded sleeve 381 is vertical. Rotate the second threaded rod 382 to engage the second threaded rod 31. Rod 382 extends from the second threaded sleeve 381 until the upper surface of the second fixing plate 383 abuts against the lower surface of the simply supported beam 1. At this point, clamp 39 can be installed. Two clamping plates 390 are placed on the simply supported beam 1 and the lower surface of the second fixing plate 383, respectively. During installation, rubber pads 391 should be in contact with the surfaces of the simply supported beam 1 and the second fixing plate 383. Double-ended bolts 392 are passed through the openings in the clamping plates 390, and second nuts 393 are screwed into both ends of the double-ended bolts 392. The two second nuts 393 are tightened respectively, so that the clamping plates 390 clamp the simply supported beam 1 and the second fixing plate 383. With plate 383 in place, the side beam support structure 3 is now installed. The side beam support structure 3 can support both ends of the simply supported beam 1 using the support 38. The relative position of the support 38 can be changed according to different load conditions on the simply supported beam 1, making it suitable for different load situations. When the load on the simply supported beam 1 is concentrated in the middle section of the simply supported beam 1, the support 38 can be placed near the middle section of the simply supported beam 1. When the load on the simply supported beam 1 is relatively uniform or the load is close to both ends of the simply supported beam 1, the support 38 can be placed near both ends of the simply supported beam 1.

[0036] To further prevent the middle section of the simply supported beam 1 from deflecting under stress, a middle beam support structure 4 is required to support the middle section of the simply supported beam 1. The fourth fixing plate 40 is installed on the end panel 5, and the fourth fixing plate 40 is fixed to the beam column 6 and the end panel 5 using the third bolt 47 and the third nut 48. The two ends of the steel cable 42 are passed through the wire hole 41 respectively, and the steel cable 42 is passed from one side of the fourth fixing plate 40 to above the fourth fixing plate 40. According to the position of the middle section of the wire hole 41, the steel cable 42 is appropriately stretched or loosened so that the position of the middle section of the steel cable 42 is flush with the lower surface of the simply supported beam 1. After determining the length of the steel cable 42, an upper limit block 43 is welded at the position where the steel cable 42 passes through the wire hole 41. The size of the upper limit block 43 is larger than the hole diameter of the fourth fixing plate 40, and the upper limit block 43 is used to limit the steel cable 42. On the other side of the simply supported beam 1, another steel cable 42 is installed in the same manner. After the two steel cables 42 are installed, eye bolts 44 are hung on the steel cables 42, with the eye bolts 44 located in the middle section of the simply supported beam 1. The eye bolts 44 are bolts with a hook at one end and threads at the other end. The steel plate 46 is slidably installed on the two eye bolts 44, and the third nut 48 is screwed on and tightened until the upper surface of the steel plate 46 is flush with the lower surface of the simply supported beam 1. The working principle is: when there is a load on the middle section of the simply supported beam 1, the middle section of the simply supported beam 1 generates a downward force. Under the action of the steel cables 42, the steel plate 46 exerts a supporting reaction on the simply supported beam 1, thereby offsetting or reducing the force exerted on the middle section of the simply supported beam 1 by the load above the simply supported beam 1, thereby avoiding or delaying the downward deflection of the middle section of the simply supported beam 1.

[0037] To make the side beam support structure 3 more stable, the foundation support structure 2 can be selectively installed to support the side beam support structure 3. The support square steel 20 is fixed to the beam column 6 by the third fixing plate 23 using the sixth bolt 24 and the sixth nut 25. The fixing method is the same as the bolt and nut fixing method to the beam column 6. The support head 21 needs to be pre-grooved and welded to the end of the support square steel 20 away from the third fixing plate 23. When fixing the third fixing plate 23, the position of the third fixing plate 23 on the beam column 6 should be adjusted according to the position of the support head 21. It should be ensured that after the third fixing plate 23 is fixed, the support head 21 is suspended below the first threaded rod 31 and the first threaded rod 31 is in contact with the arc groove 22. In this way, the support head 21 and the support square steel 20 support both ends of the first threaded rod 31, which further improves the stability of the side beam support structure 3.
