They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.
[0030] like Figures 1 to 8 As shown, a corner joint for connecting houses includes a first side panel 1 and a second side panel 3 that are bent, wherein the bending angles of the first side panel 1 and the second side panel 3 can both be 90°, and extension panels 2 are respectively provided on both sides of the first side panel 1, wherein the height of the extension panels 2 is consistent with that of the first side panel 1, and an assembly hole 11 is provided on the first side panel 1, wherein the assembly hole 11 is provided to facilitate the installation of external accessories on the first side panel 1, and a weight-reducing hole 32 corresponding to the position of the assembly hole 11 is provided on the second side panel 3.
[0031] The upper and lower ends of the second side plate 3 are respectively provided with connecting plates 4 corresponding to the extension plate 2 . There are four connecting plates 4 , which are distributed in pairs at the upper and lower ends of the bent second side plate 3 .
[0032] The first side panel 1 and the extension panel 2 are integrally formed structures, which can be punched out by a punch press. The second side panel 3 and the connecting panel 4 are integrally formed structures, which can also be punched out by a punch press. The connecting panel 4 is formed by bending 90° on the second side panel 3. Notches 31 are provided at the upper and lower ends of the bending portion of the second side panel 3. The notches 31 are provided to facilitate the bending operation of the connecting panel 4.
[0033] The first side plate 1 is fixed to the second side plate 3. Specifically, the first side plate 1 and the second side plate 3 are fixed by welding to form a column with upper and lower openings. The column is in the shape of a cube with upper and lower openings. End plates 6 are respectively welded to the upper and lower ends of the column. The contour of the end plate 6 is adapted to the inner peripheral contour of the column, and the upper and lower end plates 6 are respectively enclosed and installed at the upper and lower ports of the column.
[0034] The four sides of the end plate 6 are welded in contact with the sides of the first side plate 1 and the second side plate 3. Chamfers 63 are provided at the four corners of the end plate 6. Through the setting of the chamfers 63, the end plate 6 can be better installed on the inner periphery of the column, avoiding interference caused by the four corners of the end plate 6 during its installation.
[0035] A positioning hole 61 is provided in the middle of the end plate 6, and mounting holes 62 are provided on the outer periphery of the positioning hole 61. The positioning hole 61 can be a threaded hole.
[0036] The connecting plate 4 is fixed to the corresponding extension plate 2. Specifically, the connecting plate 4 is fixed to the corresponding extension plate 2 by welding, and the upper and lower ends of the extension plate 2 are flush with the corresponding connecting plates 4 respectively. The extension plate 2 and the upper and lower connecting plates 4 corresponding to it cooperate to form a "U" - shaped structure arranged laterally.
[0037] Through the combined method of stamping and welding, the processing and manufacturing of the corner joint are realized, improving the production efficiency of the corner joint, reducing the production cost. And when the size of the corner joint needs to be modified, the size of the subsequently manufactured corner joint can be modified by replacing the stamping die. Compared with the traditional corner joint formed by casting, the corner joint in this embodiment is more convenient for processing and manufacturing, has stronger adaptability, and is easier to adjust the size.
[0038] A plurality of countersunk holes 5 are provided on the extension plate 2 and the connecting plate 4. The countersunk holes 5 can be used for riveting fixation, and the countersunk holes 5 are inclinedly distributed on the extension plate 2 and the connecting plate 4. By the inclined distribution of the countersunk holes 5, the number of distributed countersunk holes 5 is increased, thereby improving the overall structural strength after riveting through the countersunk holes 5.
[0039] A transition section 21 bent close to the second side plate 3 is provided between the first side plate 1 and the extension plate 2. By setting the transition section 21, the extension plate 2 is distributed closer to the second side plate 3.
[0040] Reference Figures 5 to 8 As shown, when the external steel material 7 needs to be assembled through this embodiment, the steel material 7 is sleeved outside the connecting plate 4 and the extension plate 2, and the steel material 7 is arranged in contact with the extension plate 2 and the connecting plate 4. Specifically, the main plate 71 of the steel material 7 is in contact with the outside of the extension plate 2, and the auxiliary plate 72 of the steel material 7 is in contact with the outside of the connecting plate 4.
[0041] The steel material 7 is also provided with countersunk holes 5 corresponding to the connecting plate 4 and the extension plate 2, that is, the countersunk holes 5 on the main plate 71 correspond to the countersunk holes 5 on the extension plate 2, and the countersunk holes 5 on the sub-plate 72 correspond to the countersunk holes 5 on the connecting plate 4. When the steel material 7 is sleeved on the outside of the connecting plate 4 and the extension plate 2, the countersunk holes 5 on the steel material 7 are positioned inside and outside corresponding to the countersunk holes 5 on the extension plate 2 and the connecting plate 4, so that the steel material 7 and the corner joint can be quickly positioned and riveted through the corresponding countersunk holes 5, thereby improving the assembly accuracy of this embodiment during use and ensuring the efficiency and quality of installation.
[0042] Furthermore, when the countersunk holes 5 on the steel material 7 are positioned correspondingly to the countersunk holes 5 on the extension plate 2 and the connecting plate 4, one end of the main plate 71 of the steel material 7 abuts against the transition section 21 (refer to Figure 6 、 Figure 7 ) to improve the efficiency and accuracy of the steel 7 when assembled with this embodiment.
[0043] And when the countersunk holes 5 on the steel 7 correspond to the countersunk holes 5 on the extension plate 2 and the connecting plate 4, the countersunk holes 5 of the steel 7 and the countersunk holes 5 of the corner joint are abutted and matched with each other to increase the abutment area between the corner joint and the steel 7. Then, when the steel 7 and the corner joint are riveted and fixed through the countersunk holes 5, the countersunk holes 5 arranged in abutment with each other inside and outside improve the assembly structural strength of the steel 7 riveted to the corner joint.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
