Description

Technical Field

[0001] The present application relates to the technical field of wall connectors, and in particular to an autoclaved aerated concrete wall panel connecting device. Background Art

[0002] Autoclaved aerated concrete wall panels are a new type of building material, mainly made of raw materials such as cement, lime, sand, gypsum and gas generating agents. During the production process, a large number of tiny pores are generated through chemical reactions, making the concrete lightweight, heat-insulating, sound-insulating and fire-resistant. This type of wall panel is widely used in various construction fields, such as residential, commercial buildings, industrial plants, etc., mainly used for the construction of internal and external walls.

[0003] When connecting autoclaved aerated concrete wall panels, it is generally necessary to connect the wall panels with connectors to improve the stability of the entire building structure and avoid displacement of the panels due to external forces in the later stage. The connectors currently used are usually connecting plates. When connecting, the connecting plate is first installed on the edge of a plate and fixed by bolts, rivets, etc., so that one part of it covers the plate and the other part is suspended in the air to connect with the adjacent plate. Then, the same method is used to install bolts or other fasteners through the connecting plate and the second plate to connect them together. This connection method is not only inefficient, but also stress concentration may occur in the contact area between the connecting plate and the plate body, especially around bolts or welds, thereby increasing the risk of cracks or fatigue failure in the area. Utility Model Content

[0004] In order to conveniently and quickly connect two panels, the present application provides an autoclaved aerated concrete wall panel connecting device.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] A device for connecting autoclaved aerated concrete wall panels comprises a wall panel body, and side walls of the wall panel body are respectively provided with an insertion portion and a recessed portion. When the two adjacent wall panel bodies are spliced, the insertion portion of one of the wall panel bodies is inserted into the recessed portion of the other wall panel body, and a clamping member is rotated inside the recessed portion through a connecting shaft. The clamping member comprises a contact end and a clamping end, and there is a certain angle between the length extension direction of the contact end and the length extension direction of the clamping end, and a clamping groove is provided on the insertion portion. When the insertion portion contacts the contact end, the clamping member rotates around the connecting shaft so that the clamping end enters the clamping groove to realize the connection between the two adjacent wall panel bodies.

[0007] By adopting the above technical solution, when two wall panel bodies are spliced, the insertion part enters into the recessed part, so that the clamping member swings around the connecting axis and the clamping end enters into the clamping groove of the insertion part to achieve the connection between the two wall panel bodies.

[0008] Optionally, there are multiple clamping members, and the multiple clamping members correspond to the number of connecting shafts one by one, and are equidistantly arranged along the length extension direction of the wall panel body.

[0009] By adopting the above technical solution, it is convenient to disperse the force to multiple points, making the force distribution more uniform.

[0010] Optionally, there is one clamping member, and the length of the clamping member is at least two-thirds of the length of the wall panel body.

[0011] By adopting the above technical solution, one-time connection is facilitated and more convenient.

[0012] Optionally, a receiving groove for containing the connecting shaft and the clamping member is provided on the inner wall of the recessed portion, and a first magnetic sheet is provided on the inner wall of the receiving groove, and a second magnetic sheet that is attracted to the first magnetic sheet is provided on the clamping member.

[0013] By adopting the above technical solution, the position of the clamping part can be positioned before splicing through the mutual adsorption of the first magnetic sheet and the second magnetic sheet, so as to prevent the clamping end from leaking out of the accommodating groove and affecting the insertion part from entering the recessed part.

[0014] Optionally, an introduction rod is connected to the interior of the recessed portion, and an introduction hole for the introduction rod to enter is provided on the insertion portion.

[0015] By adopting the above technical solution, the two wall panel bodies can be more accurately joined together.

[0016] Optionally, the diameter of the introduction rod gradually decreases from one end away from the recessed portion.

[0017] By adopting the above technical solution, it is convenient to insert the introduction rod into the introduction hole.

[0018] Optionally, a resisting inclined surface is provided on the resisting end, and a clamping buckle is connected to the clamping end.

[0019] By adopting the above technical solution, the inclined surface of the insertion part can be easily abutted against the abutting end to drive the clamping member to swing, so that the clamping buckle enters the clamping groove for locking.

[0020] Optionally, the clamping buckle is integrally connected with the clamping piece, and the clamping piece is made of metal.

[0021] 1. By adopting the above technical solution: the connection strength of the clamping piece can be improved and its service life can be extended.

[0022] 2. By providing a clamping piece and a clamping groove, when two wall panel bodies are spliced, the clamping piece is resisted by the insertion part and swings, driving the clamping end into the clamping groove to achieve locking, thereby completing the connection between the two adjacent wall panel bodies without the aid of other tools, and the operation is more convenient.

[0023] 3. By providing the first magnetic sheet and the second magnetic sheet, the position of the clamping member can be initially fixed to prevent the clamping end from leaking out of the receiving groove and affecting the insertion portion from entering the recessed portion.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] like Figures 1-6As shown in the figure, an autoclaved aerated concrete wall panel connection device is disclosed in an embodiment of the present application, which includes a wall panel main body 1. Insertion parts 11 and recessed parts 12 are respectively provided on both side walls of the wall panel main body 1. When two adjacent wall panel main bodies 1 are spliced, the insertion part 11 of one wall panel main body 1 is inserted into the recessed part 12 of the other wall panel main body 1. A clamping member 3 is rotatably connected by a connecting shaft 2 inside the recessed part 12. The clamping member 3 includes a contact end 31 and a clamping end 32, and there is a certain angle between the length extension direction of the contact end 31 and the length extension direction of the clamping end 32. A clamping groove 13 is formed on the insertion part 11;

[0033] Specifically, when splicing two adjacent wall panel main bodies 1, first align the insertion part 11 of one wall panel main body 1 with the recessed part 12 of the other wall panel main body 1 and insert it into the recessed part 12. Preferably, the cross-sections of the insertion part 11 and the recessed part 12 are trapezoidal. At this time, the inclined surfaces on both sides of the insertion part 11 will contact the contact end 31 of the clamping member 3, causing the clamping member 3 to swing around the connecting shaft 2. When the end of the insertion part 11 is completely attached to the inner wall of the recessed part 12, at this time, the clamping end 32 will enter the clamping groove 13 to complete the connection of the two adjacent wall panel main bodies 1. Without the need to rely on external tools, the connection can be fixed while the two wall panel main bodies 1 are being spliced, which is more labor-saving and convenient.

[0034] As Figure 4 shown, the first implementation manner provided by the present utility model is that the number of the clamping members 3 is multiple, and the number of the multiple clamping members 3 corresponds to the number of the connecting shafts 2 one by one, and they are arranged at equal intervals along the length extension direction of the wall panel main body 1. Dividing the clamping members 3 into multiple parts can disperse the force to multiple points, making the force distribution more uniform, thereby reducing the risk of local stress concentration.

[0035] As Figure 5 shown, the second implementation manner provided by the present utility model is that the number of the clamping members 3 is one, and the length of the clamping member 3 accounts for at least two-thirds of the length of the wall panel main body 1. Then the connecting shaft 2 is also an integral part, passing through the clamping member 3. Setting the clamping member 3 as an integral part can provide a more concentrated connection force, but the force distribution may be relatively less uniform. Different from the first implementation manner, it is relatively simple to install and can be completed in one go; for multiple clamping members 3, the positions of the clamping members need to be adjusted separately before use. Once the position of one clamping member 3 is inaccurate, it may cause the insertion part 11 to be unable to enter the recessed part 12, and the operation is relatively cumbersome, and the requirement for installation accuracy may be higher. And the connection system formed by multiple clamping members 3 can still maintain a certain stability even if a clamping member 3 has problems; while if the overall clamping member 3 is damaged or fails, the entire connection may be greatly affected.

[0036] Furthermore, as Figure 2and Figure 3 As shown, in order to prevent the insertion part 11 from failing to enter the recessed part 12 due to the position deviation of the clamping part 3, a receiving groove 4 for accommodating the connecting shaft 2 and the clamping part 3 is formed on the inner wall of the recessed part 12. A first magnetic attracting piece 41 is provided on the inner wall of the receiving groove 4, and a second magnetic attracting piece 42 that mutually attracts with the first magnetic attracting piece 41 is provided on the clamping part 3. Before use, through the mutual attraction of the first magnetic attracting piece 41 and the second magnetic attracting piece 42, the clamping end 32 of the clamping part 3 is positioned in the receiving groove 4, and at this time, the abutting end 31 is located in the recessed part 12. When the insertion part 11 enters the recessed part 12, it will not abut against the clamping end 32, but the bevel surface of the insertion part 11 abuts against the abutting end 31 to realize the swinging of the clamping part 3.

[0037] Furthermore, a guiding rod 5 is connected inside the recessed part 12, and a guiding hole 51 for the guiding rod 5 to enter is provided on the insertion part 11. By inserting the guiding rod 5 into the guiding hole 51, the two wall panel main bodies 1 can be guided during splicing, so that one plate body moves towards the other plate body in a flush state, thereby preventing the wall panel main body 1 from deviating during initial splicing and affecting the abutment against the clamping part 3.

[0038] Furthermore, the diameter of the guiding rod 5 gradually decreases from the end far away from the recessed part 12. During the process of inserting the guiding rod 5 into the guiding hole 51, the tapered tip can help the guiding rod 5 automatically adjust its position to make its center line coincide with the center line of the guiding hole 51, which is more convenient for the guiding rod 5 to be accurately inserted into the guiding hole 51.

[0039] Furthermore, an abutting bevel surface 301 is provided on the abutting end 31, and a clamping buckle 302 is connected to the clamping end 32. When the first magnetic attracting piece 41 and the second magnetic attracting piece 42 mutually attract, the abutting bevel surface 301 can be parallel to the bevel surface of the insertion part 11. When the insertion part 11 abuts against the abutting bevel surface 301, the abutting bevel surface 301 is pressed to drive the clamping part 3 to swing around the connecting shaft 2, so that the first magnetic attracting piece 41 and the second magnetic attracting piece 42 are separated from adsorption, thereby making the clamping buckle 302 stuck in the clamping groove 13. The clamping buckle 302 is integrally formed with the clamping part 3, and the clamping part 3 is made of a metal material, such as a material with a relatively high hardness like steel, so as to improve the strength of the clamping part 3 and extend its service life.

[0040] This specific embodiment is only an interpretation of the present application, and it does not limit the present application. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
