The installation cost is high, and it will increase the installation cycle, affecting the overall efficiency and quality of the project.

[0003] The Chinese patent with publication number CN214497859U discloses an assembled steel plate concrete composite shear wall and steel beam connection structure, including a shear wall steel plate, a support seat and a steel beam, wherein a fixing platform is installed at the middle position inside the shear wall steel plate, a fixing seat is installed at a position corresponding to the fixing platform on one side of the shear wall steel plate, a support seat is installed at the middle position of the fixing seat away from the shear wall steel plate, a bottom plate is installed at the middle of the top of the support seat near the fixing seat, a support plate is installed at the top of the bottom plate at the middle position of one side of the fixing seat, a top plate is installed at the top of the support plate, and a steel beam is installed at the top of the support seat on one side of the support seat.

[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1

[0047] like Figure 1-5 As shown, the embodiment of the utility model provides an assembled building structure template, including: a steel mold 1, a first side plate 2 and a second side plate 3 arranged on both sides of the steel mold 1, the first side plate 2 and the second side plate 3 are connected to the steel mold 1 through a connecting piece 4, the first side plate 2 and the second side plate 3 rotate around the connecting piece 4 on both sides of the steel mold 1, and the connection between the shear wall 7 and the beam 8 falls between the two side plates, and is then fixed by pouring cement. The structure of the connection device is simple, and the parts are all connected as one, which reduces the difficulty of manufacturing and assembling each part, strengthens the rationality of the force of the device, makes the connection of the steel concrete wall beam more efficient, and after the pouring is completed, the device can be dismantled for recycling, and the dismantling process is also extremely convenient.

[0048] The steel formwork 1 is a U-shaped plate as a whole, the width of the bottom plate of which is greater than the width of the bottom beam at the connection between the shear wall 7 and the beam 8, and a cavity is formed between the bottom plate and the vertical plates on both sides of the bottom plate, and the bottom beam just falls into the cavity of the U-shaped plate.

[0049] The first side plate 2 is a flat plate, and its length is the same as that of the steel mold 1; the second side plate 3 is an L-shaped plate, and its vertical plate is arranged at the bottom end and connected to the vertical plate on one side of the steel mold 1, and the horizontal plate is arranged at the top end and is arranged in a direction away from the first side plate 2. The first side plate 2 and the second side plate 3 are respectively rotated on the vertical plates on both sides of the steel mold 1, and the two side plates are rotated in opposite directions. When the distance between the top ends of the two is the shortest, they are both in the same plane with the vertical plate of the steel mold 1.

[0050] like Figure 6-10As shown, the connecting member 4 is a rotating connecting member, specifically one of a pin connection, a pivot connection, a hinge connection, a sleeve connection or a loose-leaf connection. The first side panel 2 and the second side panel 3 are extensions of the vertical panels on both sides of the steel mold 1. When they rotate around the connecting member 4, the opening of the steel mold 1 changes accordingly. Before connecting with the connection between the shear wall 7 and the beam 8, the first side panel 2 and the second side panel 3 rotate outward to open, so that the opening of the steel mold 1 becomes larger, so that the bottom beam at the connection between the shear wall 7 and the beam 8 falls into the steel mold 1; after connecting with the connection between the shear wall 7 and the beam 8, before pouring concrete, the first side panel 2 and the second side panel 3 rotate inward to close, so that the opening of the steel mold 1 becomes smaller, so as to provide a fixed mold for pouring concrete.

[0051] After the connection between the shear wall 7 and the beam 8, a prefabricated composite panel needs to be placed to build a floor or a roof, so the prefabricated composite panel needs to be pre-fixed. The horizontal plate and the vertical plate of the second side plate 3 are bent, and after being connected to the connection between the shear wall 7 and the beam 8 and closed, the horizontal plate is in a horizontal direction to support the prefabricated composite panel.

The beam bottom form 5 is sprayed with fireproof mortar and embedded with anchoring steel bars 6, replacing the traditional steel mold and wooden mold. The size of the beam bottom form 5 is the same as the size of the internal cavity of the steel mold 1. Both sides of the beam bottom form 5 are provided with upward protrusions at the contact points with the vertical plates of the steel mold 1. The protrusions are provided with anchoring steel bars 6 protruding equidistantly upward to form a steel bar array. The distance between the protrusions on both sides is the same as the width of the bottom beam at the connection point between the shear wall 7 and the beam 8. The bottom beam falls into the protrusions on both sides of the beam bottom form 5 in the cavity of the steel mold 1. After the pouring is completed, the beam bottom form 5 is connected to the poured concrete as a whole through the steel bar arrays on both sides.

[0053] Preferably, the steel formwork 1, the first side plate 2 and the second side plate 3 are all made of metal plates with a thickness of 3-8 mm. The width of the bottom plate of the steel formwork 1 is determined by the width of the bottom beam at the connection between the shear wall 7 and the beam 8. The thickness of the bottom beam formwork 5 and the number of anchoring steel bars 6 are set according to the conditions on site.

[0054] Preferably, the steel mold 1, the first side plate 2 and the second side plate 3 are connected by the connecting piece 4 to form a whole that is arranged in an inverted "X" shape.

[0059] S400, on-site installation: rotate the first side plate 2 and the second side plate 3 to open their openings, put the prefabricated beam bottom mold 5 with the protrusion facing upward into the steel mold 1, align it with the beam bottom and clamp it on the connection between the shear wall 7 and the beam 8, rotate the first side plate 2 and the second side plate 3 to close their openings, and pour concrete at the connection;

[0060] S500, completion and dismantling: After the poured concrete is solidified, the first side plate 2 and the second side plate 3 are rotated to open their openings, and other structures of the connection device except the beam bottom formwork 5 are dismantled.

[0061] Example 2
