DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] like Figures 1 to 10 As shown, the utility model provides a rigid connection node of a connecting beam outside the plane of a shear wall, comprising: a first wall 400, a second wall 300, a connecting beam 200 and a floor slab 100, wherein the wall extension lines of the first wall 400 and the second wall 300 intersect, the connecting beam 200 is connected to the first wall 400 and the second wall 300, the connecting beam 200 is parallel to the second wall 300, the top of the connecting beam 200 is connected to the floor slab 100, a steel plate 220 is arranged in the connecting beam 200, a steel column 410 is arranged in the first wall 400, the steel column 410 is connected to the steel plate 220, and an in-plate steel section 110 is arranged in the floor slab 100.

[0033] The connecting beam 200 is vertically arranged with respect to the first wall 400. The connecting beam 200 is arranged at the top of the second wall 300 and connected with the second wall 300. The in-slab steel sections 110 are arranged on both sides of the connecting beam 200. One end of the in-slab steel section 110 is connected to the first wall 400, and the other end extends to the outside of the first wall 400. The in-slab steel sections 110 are arranged within the flange range on both sides of the connecting beam 200 in the floor slab 100, thereby improving the ability of the floor slab 100 to transmit horizontal forces and ensuring that the node tension in the case of moderate earthquakes is jointly borne by the in-slab steel section 110 and the concrete combination. Horse stool reinforcement 111 is arranged below the in-slab steel section 110 to support the in-slab steel section 110.

[0034] The steel plate 220 in the connecting beam 200 is arranged along the length direction of the connecting beam 200, and the large plane of the steel plate 220 is perpendicular to the horizontal plane. Such an arrangement can enhance the shear bearing capacity of the connecting beam 200. By adding reinforcing ribs 221 on both sides of the steel plate 220, the shear bearing capacity of the connecting beam 200 can be further improved.

[0035] In order to improve the strength of the connecting beam 200, a beam top steel bar 201 is arranged on the upper side of the connecting beam 200, and a beam bottom steel bar 202 is arranged on the lower side of the connecting beam 200. A plurality of beam stirrups 210 are arranged along the length direction of the beam top steel bar 201 and the beam bottom steel bar 202. The beam stirrups 210 are sleeved on the outside of the beam top steel bar 201 and the beam bottom steel bar 202 to connect the beam top steel bar 201 and the beam bottom steel bar 202, so that the connecting beam 200 has better strength and rigidity after casting, thereby improving the seismic performance of the connecting beam 200.

[0036] The steel plate 220 in the connecting beam 200 and the steel column 410 in the first wall 400 are welded to solve the problem of insufficient anchoring of the connecting beam 200. The ends of the top steel bars 201 and the bottom steel bars 202 are bent toward the middle of the connecting beam 200 to further improve the anchoring strength of the connecting beam 200.

[0037] To improve the strength and bearing capacity of the first wall 400 , the steel column 410 in the first wall 400 is a profiled steel column 410 . To improve the combined connection between the steel column 410 and the first wall 400 after casting, bolts 420 are fixedly connected to the side of the steel column 410 .

[0038] In order to improve the strength and rigidity of the floor slab 100 , a slab surface reinforcement 101 is provided on the upper side of the floor slab 100 , and a slab bottom reinforcement 102 is provided on the lower side of the floor slab 100 .

[0039] like Figures 5 to 10 As shown, the construction sequence of the steel plate 220 and the connecting beam 200 is as follows:

[0040] The first step is to install U-shaped beam stirrups 210 in the coupling beam 200 template;

[0041] The second step is to place the beam bottom reinforcement 202 inside the beam stirrup 210;

[0042] The third step is to place the steel plate 220;

[0043] Step 5: bend and close the opening of the beam stirrup 210 and perform welding;

[0044] The sixth step is to lay the slab bottom reinforcement 102, the horse stool reinforcement 111, the slab inner steel section 110 and the slab surface reinforcement 101 on the floor slab 100 template.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
