[0030] The corner column of the box house is provided with a vertical drainage hole for draining the rainwater deposited on the roof. Figure 1 Figure 3 The upper surface of the male tenon 3 is provided with a first through hole 601, the first through hole 601 extends downward along the axis direction of the male tenon 3 and penetrates the lower mounting base 1, the top surface of the female tenon 4 is provided with a second through hole 403, the second through hole 403 extends upward along the axis direction of the female tenon 4 and penetrates the upper mounting base 2, and the first through hole 601 and the second through hole 403 are coaxially arranged.

[0031] The first through hole 601 is a circular hole or a square hole, and the outer dimension of the first through hole 601 is smaller than the outer dimension of the male tenon 3; the top surface of the female tenon 4 refers to the bottom surface of the cavity of the female tenon 4, the size and shape of the second through hole 403 are the same as those of the first through hole 601, the first through hole 601 penetrates the lower mounting base 1, the second through hole 403 penetrates the upper mounting base 2, and the first through hole 601 and the second through hole 403 are coaxial, so that the whole mortise and tenon joint is vertically penetrated, water can flow into the second through hole 403 through the first through hole 601, and then be drained through the drainage hole on the column.

[0032] When the rainwater passes through the connecting position of the first through hole 601 and the second through hole 403, the rainwater may overflow from the connecting position of the first through hole 601 and the second through hole 403, further, referring to Figure 3 ​The upper surface of the male tenon 3 is provided with an annular step 602 which is concave downward, the annular step 602 is arranged outside the first through hole 601 and coaxially arranged with the first through hole 601; the top surface of the female tenon 4 is provided with an annular flange 404 which cooperates with the annular step 602, and the annular flange 404 is coaxially arranged with the second through hole 403. Wherein, the inner diameter of the annular step 602 is the same as the diameter of the first through hole 601, and the outer diameter of the annular step 602 is larger than the diameter of the first through hole 601. During manufacturing, the first through hole 601 can be reamed by a drill bit. After reaming, the annular step 602 is formed outside the first through hole 601. The depth of the drill bit is the height of the annular step 602, and the diameter of the drill bit is the outer diameter of the annular step 602. The top surface of the female tenon 4 refers to the bottom surface of the female tenon 4 cavity. The connection mode of the annular flange 404 and the top surface of the female tenon 4 can adopt hot melt adhesive bonding or one-piece forming. The cooperation between the annular flange 404 and the annular step 602 refers to that the height of the annular flange 404 is equal to the height of the annular step 602, and the outer diameter of the annular flange 404 is equal to the outer diameter of the annular step 602. When rainwater flows from the second through hole 403 into the first through hole 601, the annular flange 404 and the annular step 602 form a water retaining step. Since the connection between the first through hole 601 and the second through hole 403 is higher than the connection between the annular flange 404 and the annular step 602, the rainwater cannot climb in the opposite direction, thereby ensuring that the rainwater cannot overflow from the connection between the first through hole 601 and the second through hole 403.

[0033] In order to further enhance the waterproof effect, as a preferred embodiment, the bottom surface of the annular step 602 is provided with a waterproof pad. The waterproof pad is made of rubber or nylon material.

[0034] In order to further enhance the waterproof effect, as a preferred embodiment, further, the upper surface of the male tenon 3 is provided with a waterproof ring. The waterproof ring is made of rubber or nylon material

[0035] Further, referring to Figure 1 As an embodiment, the upper surface of the lower edge 102 and the water retaining block 5 form a positioning step 103, the female tenon 4 has a positioning section 401 which cooperates with the positioning step 103, and the locking mechanism includes a mounting hole 402 arranged on the positioning section 401 and a counterbore 104 arranged on the positioning step 103, and the mounting hole 402 and the counterbore 104 are connected by a pin or a bolt. Wherein, the positioning section 401 is part of the upper edge 202, and the positioning section 401 and the positioning step 103 realize the positioning between the male tenon 3 and the female tenon 4; the mounting hole 402 and the counterbore 104 are the same size. If a pin is used for connection, the counterbore 104 is a smooth hole, that is, the hole wall of the counterbore 104 is smooth; if a bolt is used for connection, the counterbore 104 is a threaded hole.

[0036] When the mounting hole 402 is arranged at the edge of the positioning section 401, the overall strength may be insufficient, and the locking mechanism may be unstable. Further, referring to Figure 1 , the mounting hole 402 is arranged at the center of the positioning section 401, and the axis of the mounting hole 402 intersects the axis of the connecting column 6. The center of the positioning section 401 means that the distance from the center point of the mounting hole 402 to the left and right edges of the positioning section 401 is equal, and in the height direction, the distance from the center point of the mounting hole 402 to the bottom of the positioning section 401 is equal to half the height of the positioning step 103. This arrangement can maximize the length of the mounting hole 402 and the depth of the counterbore 104, thereby achieving more stable locking of the male tenon 3 and the female tenon 4.

[0037] The corner column includes a mortise and tenon joint, including an upper column 7 and a lower column 8, the lower end of the upper column 7 is fixedly connected with the upper end of the upper mounting seat 2, the upper end of the lower column 8 is fixedly connected with the lower end of the lower mounting seat 1, the lower column 8 is provided with a third mounting groove 801 matched with the first mounting groove 101, and the upper column 7 is provided with a fourth mounting groove 701 matched with the second mounting groove 201;

Similarly, the connection between the lower stand column 8 and the lower mounting base 1 can be integrated or bolted, and when the lower stand column 8 and the lower mounting base 1 are steel parts, they can also be connected by welding. The third mounting groove 801 and the fourth mounting groove 701 are used for mounting curtain wall materials. The cooperation between the first mounting groove 101 and the third mounting groove 801 means that the projections of the first mounting groove 101 and the third mounting groove 801 on the horizontal plane coincide. The cooperation between the second mounting groove 201 and the fourth mounting groove 701 means that the projections of the second mounting groove 201 and the fourth mounting groove 701 on the horizontal plane coincide. After the upper stand column 7 and the lower stand column 8 are connected by the mortise and tenon joint, the first mounting groove 101, the second mounting groove 201, the third mounting groove 801 and the fourth mounting groove 701 together serve as the mounting groove of the curtain wall material. The first channel 802 and the first through hole 601 are the same in size and shape, which facilitates the flow of rainwater from the first channel 802 into the first through hole 601. The second channel 702 and the second through hole 403 are the same in size and shape, which facilitates the flow of rainwater from the second through hole 403 into the second channel 702. After the upper stand column 7 and the lower stand column 8 are connected by the mortise and tenon joint, the first channel 802, the first through hole 601, the second channel 702 and the second through hole 403 form the flow channel of rainwater.
