[0036] The inventors found in the practice of the embodiments of the present invention that in the prior art, as the weight of the prefabricated exterior wall panels increases with the size, the vertical downward gravity load applied to the connecting brackets becomes greater, and the connecting brackets are in a complex stress state during use, affecting safety.

[0037] In view of the above problems, an embodiment of the present invention provides a connecting bracket and a wall connecting structure to solve the technical defect in the prior art that the connecting bracket is in a complex stress state when in use.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention is clearly and completely described below in combination with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] Figure 1 FIG. 1 is a schematic diagram of a wall connection structure with a connection bracket according to an embodiment of the present invention. Figure 1 shown.

[0041] The embodiment of the present invention provides a connecting bracket, comprising: a through wire 10, a pre-tightening member 20 and a connecting member 30. The through wire 10 comprises a fixed section and an adjusting section, and a first nut 11 threadedly connected to the through wire 10 is provided between the fixed section and the adjusting section. The pre-tightening member 20 is located between the first nut 11 and the fixed section, one end of the pre-tightening member 20 is fixed, and the other end abuts against the first nut 11. The connecting member 30 is connected to the adjusting section.

[0042] The technical solution provided by the embodiment of the present invention is to tighten the first nut 11 in the direction of the fixed section of the through wire 10. Since the pre-tightening member 20 prevents the first nut 11 from continuing to move, a pre-tightening force is generated between the first nut 11 and the pre-tightening member 20, thereby generating a pre-tensioning force inside the through wire 10 through the pre-tightening member 20 to offset the stress of the through wire 10 in the vertical direction, so that the through wire 10 is in a zero-stress working state, reducing the stress complexity of the connecting bracket and improving the connection safety. At the same time, the relationship between the torque applied by the nut and the pre-tensioning force generated by the through wire 10 can be obtained by calculation, thereby meeting the application requirements of different projects.

[0043] In the embodiment of the present invention, the through wire 10 includes but is not limited to a solid rod with a thread throughout the length, and the first nut 11 can be freely adjusted on the through wire 10. The preload member 20 has a certain amount of deformability, so that when the first nut 11 is prevented from moving further, a pretension is generated inside the through wire 10.

[0044] For example, the connection bracket can realize the connection between the prefabricated exterior wall panel and the main building structure. Figure 1The fixed section of the wire 10 is fixedly connected to the main building structure 40. The fixing method can be implemented in different ways according to the main building structure 40. For example, when the main building structure is a steel structure, a connection hole can be set on the steel structure, and the wire 10 can be fixed by a nut. If the main building structure is a concrete structure, the wire 10 can be fixed by pre-embedding.

[0045] One end of the preload member 20 is fixed and abuts against the main building structure 40, and the other end abuts against the first nut 11. The fixing of one end of the preload member 20 may refer to that one end of the preload member 20 is fixed to the main building structure 40 or to the wire 10, or may refer to that the position of one end of the preload member 20 is fixed. The function of fixing one end of the preload member 20 is to provide support for the other end. The fixed end of the preload member 20 may abut against the main building structure 40 to transfer the force of the other end to the main building structure 40. The other end of the preload member 20 abuts against the first nut 11. When the first nut 11 is tightened in the direction of the fixed section of the wire 10, the preload member 20 prevents the first nut 11 from moving further, so that a preload force is generated between the first nut 11 and the preload member 20, thereby generating a pretension force inside the wire 10 through the preload member 20.

[0046] The connecting piece 30 is connected to the adjustment section and the wall 50 respectively. The wall 50 applies a vertical downward gravity load to the wire 10 through the connecting piece 30. The gravity load of the wall 50 and the pre-tension in the wire 10 offset each other. The wire 10 is in a zero-stress working state in the vertical direction, which reduces the stress complexity of the connecting bracket and improves the connection safety.

[0047] The connecting bracket provided in the embodiment of the present invention is further introduced below.

[0048] In the embodiment of the present invention, when the main building structure is a steel structure, the fixing section of the wire 10 can be fixed by a nut. Figure 1 The fixing section is threadedly connected with a second nut 12 and a third nut 13, and the second nut 12 and the third nut 13 form a clamping structure to fix the fixing section to the first preset structure. The first preset structure includes but is not limited to a steel beam on the main building structure 40, such as an I-beam. The I-beam is provided with a connecting hole, through which the through wire 10 passes, and the second nut 12 and the third nut 13 are respectively located on both sides of the I-beam to form a clamping structure. After tightening the second nut 12 and the third nut 13 respectively, the through wire 10 is fixed to the steel beam.

[0049] In order to further improve the connection strength between the second nut 12 and the third nut 13, in the embodiment of the present invention, a wedge-shaped pad 14 is further provided between the second nut 12 and the third nut 13. The wedge-shaped pad 14 is sleeved on the fixed section. The stress between the second nut 12 and the third nut 13 can be enhanced by the wedge-shaped pad 14, thereby improving the connection strength between the second nut 12 and the third nut 13. The wedge-shaped pad 14 can be provided between the second nut 12 and the steel beam, or the wedge-shaped pad 14 can be provided between the third nut 13 and the steel beam.

[0050] See also Figure 1 and Figure 2 In an achievable embodiment of the present invention, the pre-tightening member 20 includes an intermediate connecting plate 21, a first side plate 22 and a second side plate 23 disposed on opposite sides of the intermediate connecting plate 21. The intermediate connecting plate 21, the first side plate 22 and the second side plate 23 enclose a C-shaped structure, or the pre-tightening member 20 includes but is not limited to being made of channel steel.

[0051] A concentric first through hole 221 and a second through hole 231 are respectively provided at corresponding positions on the first side plate 22 and the second side plate 23. The first side plate 22 and the second side plate 23 are respectively sleeved on the through wire 10 through the concentric first through hole 221 and the second through hole 231. Different numbers of through holes on each side plate can be set according to different working conditions, that is, the number of first through holes 221 can be one, two or more, and the number of second through holes 231 at corresponding positions is also one, two or more. Correspondingly, the number of through wires 10 is also one, two or more. The first side plate 22 abuts against the first nut 11 to prevent the first nut 11 from moving, and transmits the corresponding force to the second side plate 23 through the middle connecting plate 21.

[0052] The second side plate 23 is located between the second nut 12 and the third nut 13. The second nut 12 and the third nut 13 tightly clamp the fixed section of the wire 10, the second side plate 23 and the main building structure 40 together to achieve the purpose of fixing the wire 10. The pre-tightening member 20 passes through the wire 10 through the first through hole 221 on the first side plate 22 and the second through hole 231 on the second side plate 23, respectively, and then the second side plate 23 is fixed to the main building structure through the second nut 12 and the third nut 13 to achieve the purpose of fixing the pre-tightening member 20. In order to further improve the connection strength of the second side plate 23, a wedge-shaped pad 14 can be set between the second nut 12 and the second side plate 23.

[0053] See also Figure 1 and Figure 3In an achievable embodiment of the present invention, the connecting member 30 includes a first connecting plate 31 and a second connecting plate 32. The first connecting plate 31 is provided with a third through hole 311, and the first connecting plate 31 is sleeved on the adjusting section through the third through hole 311. The number of the third through holes 311 corresponds to the number of the through wires 10, that is, it can also be one, two or more. The first connecting plate 31 can be connected to the through wire 10 through nuts. One achievable way is that the fourth nut 15 and the fifth nut 16 are respectively threadedly connected on both sides of the first connecting plate 31, and the fourth nut 15 and the fifth nut 16 clamp the first connecting plate 31 to limit the connection position of the first connecting plate 31 relative to the adjusting section. By adjusting the corresponding positions of the fourth nut 15 and the fifth nut 16, the axial position of the connecting member 30 relative to the through wire 10 can be adjusted, that is, parallel to the through wire 10. Figure 1 The upper and lower position relationship of the paper.

[0054] In order to further enhance the connection strength between the fourth nut 15 and the fifth nut 16 and the first connecting plate 31, in the embodiment of the present invention, a reinforcing pad 17 is provided between the fourth nut 15 and / or the fifth nut 16 and the first connecting plate 31. Figure 1 As shown in the figure, the reinforcing pad 17 is located between the fourth nut 15 and the first connecting plate 31. The axial position of the connector 30 relative to the through-wire 10 can be adjusted by the reinforcing pad 17 and the fourth nut 15. The reinforcing pad 17 can be a long pad, and the long pad is provided with the same number of connecting holes as the third through hole 311, so as to achieve the purpose of connecting multiple through-wires 10 with the same long pad. Alternatively, the reinforcing pad 17 can be a short pad, and the short pad is provided with a connecting hole, so as to achieve the purpose of connecting different through-wires 10 to each short pad.

[0055] Further, see Figure 1 and Figure 3 One implementation of the connector 30 is that the first connecting plate 31 is perpendicular to the second connecting plate 32 to form an L-shaped structure. The connector 30 includes but is not limited to being made of angle steel. In order to enable the connector 30 to be adjusted in the horizontal direction, the third through hole 311 on the first connecting plate 31 is an oblong hole, and the third through hole 311 extends in a direction perpendicular to the second connecting plate 32. The horizontal position of the connector 30 relative to the through wire 10 can be adjusted by adjusting the position of the through wire 10 at the third through hole 311, that is, parallel to the through wire 10. Figure 1 The left and right position relationship of the paper.

[0056] In the embodiment of the present invention, the second connecting plate 32 is used to connect with the wall 50, and the connection can be achieved in different ways according to different working conditions, such as the second connecting plate 32 can be connected to the wall 50 by bolts. One possible way is that the second connecting plate 32 is provided with a fourth through hole 321, and the fastener 18 can pass through the fourth through hole 321 to fix the second connecting plate 32 to the second preset structure. The second preset structure includes but is not limited to the wall 50, and the fastener 18 includes but is not limited to bolts, screws, rivets, etc. In order to enhance the connection strength between the second connecting plate 32 and the wall 50, a pad can be provided between the second connecting plate 32 and the wall 50.

[0057] In order to adjust the relative position between the connecting member 30 and the wall 50, the fourth through hole 321 on the second connecting plate 32 is an oblong hole, and the fourth through hole 321 extends in a direction parallel to the first connecting plate 31. The position of the connecting member 30 relative to the wall 50 can be adjusted by adjusting the position of the fastener 18 at the fourth through hole 321, that is, perpendicular to the wall 50. Figure 1 The positional relationship of the paper direction.

[0058] Example 2

[0059] Based on the embodiment 1, the embodiment of the present invention further provides the embodiment 2, which provides a wall 50 connection structure, including: a main building structure 40, a wall 50 and a connection bracket. The connection bracket can be realized by the connection bracket in the embodiment 1, and the related features in the following embodiment 2 and embodiment 1 can be mutually referenced, borrowed and combined.

[0060] Specifically, see Figure 1 The embodiment of the present invention further provides a wall 50 connection structure, including: a main building structure 40, a wall 50 and a connection bracket.

[0061] The connecting support comprises: a through wire 10, a pre-tightening member 20 and a connecting member 30. The through wire 10 comprises a fixed section and an adjusting section, and a first nut 11 threadedly connected to the through wire 10 is arranged between the fixed section and the adjusting section. The fixed section is fixedly connected to the main building structure 40. The pre-tightening member 20 is located between the first nut 11 and the fixed section, one end of the pre-tightening member 20 is fixed and abuts against the main building structure 40, and the other end abuts against the first nut 11. The connecting member 30 is respectively connected to the adjusting section and the wall 50.

[0062] The technical solution provided by the embodiment of the present invention is to tighten the first nut 11 in the direction of the fixed section of the through wire 10. Since the pre-tightening member 20 prevents the first nut 11 from continuing to move, a pre-tightening force is generated between the first nut 11 and the pre-tightening member 20, thereby generating a pre-tensioning force inside the through wire 10 through the pre-tightening member 20 to offset the stress of the through wire 10 in the vertical direction, so that the through wire 10 is in a zero-stress working state, reducing the stress complexity of the connecting bracket and improving the connection safety. At the same time, the relationship between the torque applied by the nut and the pre-tensioning force generated by the through wire 10 can be obtained by calculation, thereby meeting the application requirements of different projects.

[0063] In one possible embodiment of the present invention, see Figures 1 to 3 , the through wire 10 includes but is not limited to a solid rod with a thread throughout the length, and the first nut 11 can be freely adjusted on the position of the through wire 10. The preload member 20 includes but is not limited to a channel steel, and the preload member 20 includes an intermediate connecting plate 21, a first side plate 22 and a second side plate 23 arranged on opposite sides of the intermediate connecting plate 21, and the first side plate 22 and the second side plate 23 are respectively provided with concentric first through holes 221 and second through holes 231 at corresponding positions. The first side plate 22 and the second side plate 23 are respectively sleeved on the through wire 10 through the concentric first through holes 221 and the second through holes 231. The channel steel has a certain amount of deformability, so that when the first nut 11 is prevented from continuing to move, a pre-tensioning force is generated inside the through wire 10. The connecting member 30 includes but is not limited to an angle steel, and the first connecting plate 31 of the angle steel is provided with a third through hole 311, and the second connecting plate 32 is provided with a fourth through hole 321, and the third through hole 311 and the fourth through hole 321 are both oblong holes. The specific implementation method of the connecting bracket can refer to the solution described in the above embodiment 1, and will not be described in detail here.

[0064] The wall 50 connection structure provided by the embodiment of the present invention is introduced below through specific examples.

[0065] See also Figures 1 to 3A connecting bracket used between a wall 50 and a main building structure, wherein the wall 50 includes but is not limited to a prefabricated exterior wall panel, and the connecting bracket includes: a through wire 10, a channel steel (i.e., a pre-tightening member 20), an angle steel (i.e., a connecting member 30), a fixing nut (including a second nut 12, a third nut 13, a fourth nut 15, and a fifth nut 16), a pre-tensioning nut (a first nut 11), a reinforcing pad 17, a wedge-shaped pad 14, and a bolt (i.e., a fastener 18). The lower end of the through wire 10 is fixed to the main building structure. If the main building structure 40 is a steel structure, that is, the main building structure connected to the connecting bracket is a steel beam, the lower end of the through wire 10 can be clamped together by two fixing nuts, such as the second nut 12 and the third nut 13, so as to achieve the purpose of fixing the through wire 10. The channel steel passes through the through-wire 10 through the circular holes of the upper and lower flanges, and the lower flange is fixed to the main building structure through the fixing nut and the wedge-shaped pad 14, thereby achieving the purpose of fixing the channel steel. The pre-tensioning nut passes through the through-wire 10 and is placed on the outer side of the upper flange of the channel steel. After the pre-tensioning nut is tightened, the channel steel prevents the pre-tensioning nut from continuing to move downward, which will generate tension inside the through-wire 10. The angle steel passes through the through-wire 10 through the oblong hole of the horizontal limb, and the horizontal position of the angle steel relative to the through-wire 10 can be adjusted (to be parallel to Figure 1 The left and right position relationship of the paper surface), through the long pad and the height adjustment nut (the fourth nut 15), the vertical position of the angle steel relative to the wire 10 can be adjusted (to be parallel to Figure 1 The bolts can connect the prefabricated exterior wall panels and the angle steels. The long round holes on the vertical limbs of the angle steels can be used to adjust the front-to-back position of the prefabricated exterior wall panels relative to the angle steels (to be perpendicular to the Figure 1 position relationship on paper).

[0066] The on-site installation process of the wall 50 connection structure is as follows:

[0067] 1) Fixing the wire 10 on the main building structure. If the main building structure is a steel structure, the wire 10 can be fixed by the second nut 12 and the third nut 13. If the main building structure is a concrete structure, the wire 10 can be fixed by pre-embedded method;

[0068] 2) Pass the lower flange of the channel steel through the wire 10, then pass the wedge-shaped pad 14 and the second nut 12 through the wire 10, and finally pass the upper flange of the channel steel through the wire 10, and fix the channel steel to the main building structure through the wedge-shaped pad 14 and the second nut 12, so that the lower flange of the channel steel abuts against the main building structure;

[0069] 3) Pass the pre-tension nut (first nut 11) through the through wire 10, place it on the outer side of the upper flange of the channel steel, and continue to tighten it, using a torque wrench to apply the torque value calculated in advance;

[0070] 4) Pass the height adjustment nut (fourth nut 15), the long pad and the horizontal leg of the angle steel through the through wire 10, and find the required height through the height adjustment nut, find the required front and rear position through the oblong hole on the horizontal leg of the angle steel, and then fix the angle steel with the fifth nut 16;

[0071] 5) Use bolts to connect the prefabricated exterior wall panels and the vertical limbs of the angle steel, find the required left and right positions through the oblong holes on the vertical limbs of the angle steel, and then tighten the bolts to complete the fixing of the prefabricated exterior wall panels.

[0072] The relevant features in Example 2 and Example 1 can be referenced and borrowed from each other, and will not be described in detail here.

[0073] In summary, the technical solution provided by the embodiment of the present invention has the following effective effects:

[0074] 1. The wall can be installed on site to achieve three-dimensional adjustment in front and back, left and right, and up and down, without welding, green and pollution-free;

[0076] 3. The processing and production of the connecting bracket does not require customized processes such as mold opening and pressing, and the processing and manufacturing cost is low and the efficiency is high;

[0077] 4. The gravity load of the prefabricated exterior wall panel and the pre-tension in the through-wire offset each other, and the through-wire is in a zero-stress working state in the vertical direction, which reduces the stress complexity of the connecting bracket and improves the connection safety.
