[0007] Furthermore, the depth of the groove is smaller than the radius of the first connecting rod.

[0008] Furthermore, the diameter of the groove is consistent with the diameter of the first connecting rod.

[0009] Furthermore, the connecting plate is a long strip plate having the same length as the wall plate, and a plurality of stress holes are opened on the connecting plate along the length direction.

[0010] Furthermore, the first connecting rod is provided with threads throughout or at its end, and the first connecting rod passes through the second penetration hole and is threadedly connected to a nut.

[0011] Furthermore, an end of the second connecting rod is flush with a side surface of the wall panel.

[0012] Furthermore, rib plates are respectively arranged on both sides of the right-angle connector, and the rib plates are connected to the first side plate and the second side plate.

[0013] The present invention also discloses a method for connecting an assembled wall panel and an H-shaped steel frame, which is implemented based on the above-mentioned connection structure of the assembled wall panel and the H-shaped steel frame and includes the following steps.

[0014] a. During the production stage, a plug-in rod is connected to one side of the surface of the H-shaped steel flange plate, a connecting plate is embedded in the wall panel, and a plurality of first connecting rods and a plurality of second connecting rods are respectively connected to both sides of the connecting plate to make a right-angle connector.

[0015] b. Place the wall panel in the H-steel frame so that the end face of the wall panel contacts the surface of the flange plate of the H-steel, and the first connecting rod of the wall panel and the plug-in rod of the I-steel are on the same side. Adjust the position of the wall panel so that the first connecting rod of the wall panel and the plug-in rod on the I-steel correspond to each other.

[0016] c. Place a right-angle connector between each set of first connecting rods and plug-in rods, so that the first side plate of the right-angle connector contacts the surface of the flange plate of the I-beam, the plug-in rod passes through the first connecting hole on the first side plate, the second side plate of the right-angle connector contacts the surface of the wall panel, the end of the first connecting rod passes through the second connecting hole on the second side plate, and the first connecting rod is located between the groove and the protrusion.

[0020] In the connection structure of the prefabricated wall panels and the H-shaped steel frame of the present invention, under normal working conditions, the first connecting rod is located in the groove, which limits the free movement of the wall panels and ensures the tightness of the connection between the wall panels and between the wall panels and the H-shaped steel frame. When an earthquake occurs, the strength and rigidity of the wall panels themselves first bear the load of the earthquake. When the load of the earthquake is greater than a certain value, the first connecting rod and the protrusion and the groove are deformed, so that the first connecting rod can move in the second connecting hole, so that the connection structure can meet the requirements of coordinated deformation of the steel structure.

[0021] In traditional nodes, cracks often first appear at the joints under earthquakes, indicating that the joints are where stress is concentrated. The connection structure of the present invention pre-buries the connection plate into the wallboard, thereby dispersing the stress of the connection structure, making the connection structure more reliable and avoiding premature damage to the wallboard due to stress concentration.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] The present invention is a connection structure of an assembled wall panel 1 and an H-shaped steel frame, such as Figure 1 , Figure 2 As shown, its structure includes H-shaped steel 2, wall panel 1 and right-angle connecting piece 3.

[0032] A connecting plate 4 is arranged inside the top of the wall panel 1 , and the connecting plate 4 is parallel to the surface of the wall panel 1 . A plurality of first connecting rods 5 and a plurality of second connecting rods 6 are respectively connected to the two side surfaces of the connecting plate 4 , and the first connecting rods 5 extend out of the surface of the wall panel 1 .

[0033] A plug-in rod 2-1 is arranged on the surface of the flange plate of the H-shaped steel 2, and the plug-in rod 2-1 is located on the top surface of the top flange plate or on the bottom surface of the bottom flange plate.

[0034] The end face of the wall panel 1 contacts the flange plate of the H-shaped steel 2. When the H-shaped steel 2 is located above the wall panel 1, the upper end face of the wall panel 1 contacts the bottom surface of the lower flange plate of the H-shaped steel 2. When the H-shaped steel 2 is located below the wall panel 1, the lower end face of the wall panel 1 contacts the top surface of the upper flange plate of the H-shaped steel 2.

[0035] The wall panel 1 and the flange plate of the H-shaped steel 2 form a vertical structure, and a right-angle connector 3 is arranged at the structure to connect the wall panel 1 and the H-shaped steel 2.

[0036] like Figure 3 , Figure 5 As shown, the right-angle connector 3 includes a first side plate 3-1 and a second side plate 3-2 which are perpendicular to each other, a first through hole 3-3 is provided on the first side plate 3-1, and a second through hole 3-4 is provided on the second side plate 3-2. The first through hole 3-3 is a round hole, and the second through hole 3-4 is a long hole. The length direction of the second through hole 3-4 is parallel to the first side plate 3-1. An arc-shaped groove 3-5 is provided on one side of the middle of the second through hole 3-4, and an arc-shaped protrusion 3-6 is provided on the other side, so that the second through hole 3-4 forms a certain arc curve in the middle.

[0037] Among them, the first side plate 3-1 contacts the flange plate of the H-shaped steel 2, the plug-in rod 2-1 is connected to the first through hole 3-3, the second side plate 3-2 contacts the surface of the wall panel 1, the end of the first connecting rod 5 passes through the groove 3-5 and the protrusion 3-6 of the second through hole 3-4, and the spacing between the long sides of the first through hole 3-3 is consistent with the diameter of the first connecting rod 5.

[0038] Nuts are screwed onto the ends of the plug-in rod 2 - 1 and the first connecting rod 5 , and the H-shaped steel 2 , the wall panel 1 and the right-angle connector 3 are connected and fixed to each other through the nuts.

[0039] like Figure 4 As shown, the connecting plate 4 is a long strip of the same length as the wall panel 1, which is embedded in the upper end and / or lower end of the wall panel 1 when the wall panel 1 is manufactured. A plurality of stress holes 4-1 are opened on the connecting plate 4 along the length direction to disperse the stress of the connecting plate 4 and avoid premature damage of the wall panel 1 due to stress concentration.

[0040] The first connecting rod 5 and the second connecting rod 6 are both connected to the surface of the connecting plate 4 by welding. The number of the first connecting rod 5 and the second connecting rod 6 is the same and they are located on both sides of the same position on the connecting plate 4 .

[0041] The end of the second connecting rod 6 is flush with the side surface of the wall panel 1 , and the end of the second connecting rod 6 cannot be exposed outside the wall panel 1 .

[0042] The first connecting rod 5 is provided with a thread on the whole or at the end thereof, and the thread is used to connect the nut. The surface of the second connecting rod 6 may also be provided with a thread, thereby increasing the connection area and connection strength between the second connecting rod 6 and the wall panel 1. When the connection structure is subjected to force, the external force is mainly transmitted to the first connecting rod, and the force between the second connecting rod 6 on the other side of the connecting plate 4 and the wall panel 1 can reduce the deformation of the connecting plate 4 and avoid stress concentration.

[0043] The stress holes 4 - 1 and the first connecting rods 5 / second connecting rods 6 are evenly and alternately distributed along the length direction of the connecting plate 4 , and the number of the stress holes 4 - 1 is one more than the number of the first connecting rods 5 / second connecting rods 6 .

[0044] The plug-in rod 2-1 is connected to the flange plate surface of the H-shaped steel 2 by welding. The position of the plug-in rod 2-1 corresponds to the position of the first connecting rod 5, so that the right-angle connector 3 can be installed at the right-angle structure formed by the flange plate of the H-shaped steel 2 and the wall panel 1.

[0045] In addition to the first side plate 3-1 and the second side plate 3-2 which are perpendicular to each other, the right angle connector 3 is also provided with ribs 3-7 on both sides of the right angle connector 3. The ribs 3-7 are connected to the first side plate 3-1 and the second side plate 3-2. The ribs 3-7 are triangular structures. The ribs 3-7 can enhance the overall strength of the right angle connector 3, prevent its deformation, and ensure the verticality of the first side plate 3-1 and the second side plate 3-2. When subjected to external force, the right angle connector 3 will not be deformed as a whole.

[0046] like Figure 6 As shown, the first connecting rod 5 passing through the second penetration hole 3-4 is limited by the groove 3-5 and the protrusion 3-6. The first connecting rod 5 is located in the groove 3-5 and is limited by the protrusion 3-6 to leave the groove 3-5. In this way, under normal circumstances, the groove 3-5 fixes the position of the first connecting rod 5, which can prevent the movement of the wall panels 1, thereby ensuring the tightness of the connection between the wall panels 1 and between the wall panels 1 and the H-shaped steel 2. When an earthquake occurs, when the force applied to the wall is small, the wall bears the external force. When the force applied to the wall is large, the first connecting rod 5 undergoes a certain deformation, and the two sides of the groove 3-5 and / or the edge of the protrusion 3-6 are deformed or damaged, so that the first connecting rod 5 is disengaged from the groove 3-5, and the first connecting rod 5 can move in the second penetration hole 3-4, so that the entire connection structure has a strong deformation coordination ability, reducing damage to the wall.

[0047] The depth of the groove 3 - 5 is smaller than the radius of the first connecting rod 5 , so that the first connecting rod 5 can be easily removed from the groove 3 - 5 .

[0048] The diameter of the groove 3 - 5 is consistent with the diameter of the first connecting rod 5 , so that the first connecting rod 5 will not shake when in the groove 3 - 5 , thereby ensuring the stability of the connection under normal circumstances.

[0049] The present invention also discloses a method for connecting an assembled wall panel 1 and an H-shaped steel frame. The method is implemented based on the aforementioned connection structure of the assembled wall panel 1 and the H-shaped steel frame and includes the following steps.

[0050] a. During the production phase, a plug-in rod 2-1 is connected to one side of the surface of the flange plate of the H-shaped steel 2, a connecting plate 4 is embedded in the wall panel 1, and a plurality of first connecting rods 5 and a plurality of second connecting rods 6 are respectively connected to both sides of the connecting plate 4 to make a right-angle connector 3.

[0051] The plug-in rod 2-1 is fixed to the surface of the flange plate of the H-shaped steel 2 by welding, and the first connecting rod 5 and the second connecting rod 6 are fixed to both sides of the connecting plate 4 by welding. The first side plate 3-1, the second side plate 3-2 and the rib plate 3-7 of the right-angle connector 3 are fixedly connected by welding.

[0052] The wall panel 1 is an ALC wall panel 1 . When the wall panel 1 is manufactured, a connecting plate 4 is pre-embedded in the wall panel 1 .

[0053] The above production process is all carried out in the factory, which can improve production efficiency and ensure product quality. In the subsequent installation process, workers only need to install nuts to achieve fixed connection. The installation operation is simple and convenient, and the installation and construction efficiency is high.

[0054] b. Place the wall panel 1 in the frame of the H-beam 2 so that the end face of the wall panel 1 contacts the surface of the flange plate of the H-beam 2, and the first connecting rod 5 of the wall panel 1 and the connecting rod 2-1 of the I-beam are located on the same side. Adjust the position of the wall panel 1 so that the first connecting rod 5 of the wall panel 1 and the connecting rod 2-1 on the I-beam correspond to each other.

[0055] c. Place a right-angle connector 3 between each group of first connecting rods 5 and the plug-in rod 2-1, so that the first side plate 3-1 of the right-angle connector 3 contacts the surface of the flange plate of the I-beam, the plug-in rod 2-1 passes through the first connecting hole on the first side plate 3-1, the second side plate 3-2 of the right-angle connector 3 contacts the surface of the wall panel 1, the end of the first connecting rod 5 passes through the second connecting hole on the second side plate 3-2, and the first connecting rod 5 is located between the groove 3-5 and the protrusion 3-6.

[0056] d. Install nuts on the ends of the plug-in rod 2-1 and the first connecting rod 5 and tighten them.

[0057] For aesthetics of installation, the side of the wall panel 1 away from the first connecting rod 5 is designed to be flush with the edge of the flange plate of the H-shaped steel 2 away from the plug-in rod 2-1.

[0058] The upper and lower frames of the H-shaped steel frame use the H-shaped steel 2 made in step a, and connecting plates 4 are pre-embedded at the upper and lower ends of the wall panel 1, and the wall panel 1 is connected to the H-shaped steel frame through the upper and lower ends.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some or all of the technical features may be replaced by equivalents.
