As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 in conjunction with fig. 2, an embodiment of the present invention provides a beam-column connection structure 100. The beam column connection structure 100 includes: a post 110, a corbel 120, a beam 130, a first layer of flexible material 140, and a second layer of flexible material 150.
Specifically, the column 110 is cast of steel bars and concrete. The beam 130 is cast of steel reinforcement and concrete. During construction, the steel reinforcement frame of the bracket 120 is arranged in the steel reinforcement frame of the column 110, and then the column 110 and the bracket 120 are poured with concrete, so as to form the reinforced concrete column 110 and the bracket 120 pre-embedded in the column 110.
One end of the corbel 120 is pre-buried inside the column 110 and the other end protrudes from the side of the column 110.
One end of the beam 130 is disposed on the extension 121 of the corbel 120 protruding from the side of the column 110 and connected to the column 110.
Specifically, during construction, after the concrete strength of the column 110 and the bracket 120 meets the specification requirement, a beam 130 formwork is installed, then beam reinforcements are arranged in the beam 130 formwork, and finally concrete is poured in the beam formwork to form the reinforced concrete beam 130. One end of the beam 130 is disposed on the protruding portion 121 of the corbel 120 and is connected to the column 110, thereby forming the beam-column connecting structure 100.
A first layer of flexible material 140 is disposed between beam 130 and column 110. A second layer of flexible material 150 is disposed between the beam 130 and the extended portion 121 of the corbel 120.
Specifically, the first flexible material layer 140 may be an asphalt layer or a linoleum layer. The second layer of flexible material 150 may be a layer of asphalt or a layer of linoleum. In this embodiment, the first flexible material layer 140 is an asphalt layer and the second flexible material layer 150 is an oil felt layer. The thickness of the first layer of flexible material 140 may be 1.5cm to 2.5cm, e.g., 1.5cm, 1.8cm, 2cm, 2.5cm, etc. Specifically, before the beam formwork is installed, a first flexible material layer 140 may be disposed on one side of the column 110 close to the beam 130, and a second flexible material layer 150 may be disposed on the extension 121 of the corbel 120, so that after the reinforced concrete beam 130 is cast, the first flexible material layer 140 is formed between the beam 130 and the column 110, and the second flexible material layer 150 is formed between the extension 121 of the corbel 120 and the beam 130.
In the beam-column connecting structure 100, the first flexible material layer 140 is arranged between the beam 130 and the column 110, and the second flexible material layer 150 is arranged between the extension part 121 of the bracket 120 and the beam 130, so that the connecting joint of the beam 130 and the column 110 is flexibly connected, and the seismic fortification requirement under certain specific conditions can be met. For example, when the difference between the quantities of the two units of the structure is large, the beam 130 and column 110 connection nodes of the two units can be flexibly connected to meet the requirement of seismic fortification. For example, in the existing high-rise building, the upper part is an office, an apartment or a hotel, the lower part is a commercial complex, a device interlayer is often arranged at the upper part and the lower part, the layer height of the device interlayer is generally very low, the rigidity ratio of the device interlayer to the lower layer is often large in the structural calculation process, and the requirement of the specification is difficult to meet.
In one embodiment, the flowability of the second flexible material layer 150 is less than the flowability of the first flexible material layer 140.
Specifically, in the present embodiment, the first flexible material layer 140 is an asphalt layer, and the second flexible material layer 150 is an asphalt layer, and the flowability of the asphalt layer is smaller than that of the asphalt layer. Since one end of the beam 130 is disposed on the protruding portion 121 of the corbel 120 and the second flexible material layer 150 is disposed between the protruding portion 121 of the corbel 120 and the beam 130, the second flexible material layer 150 bears a part of the weight of the beam 130. Since the second flexible material layer 150 has low fluidity, it is not easily deformed by the weight of the load beam 130.
In one embodiment, the first flexible material layer 140 is provided with an asphalt flame retardant, so as to provide a fire-proof function.
In one embodiment, the second flexible material layer 150 is provided with an asphalt flame retardant, so as to provide a fire-proof function.
The embodiment of the present application further provides a manufacturing method of the beam-column connection structure 100. The method comprises the following steps:
a bracket steel bar is arranged in the frame of the column steel bar;
pouring concrete to the column reinforcing steel bars and the bracket reinforcing steel bars to form reinforced concrete columns and brackets;
installing a beam template, arranging an asphalt layer between the reinforced concrete column and the beam template, and arranging an oil felt layer on a protruding part of the bracket, which extends out of the side surface of the reinforced concrete column;
and arranging beam reinforcing steel bars in the beam template, and pouring concrete to form the reinforced concrete beam.
In the manufacturing method of the beam-column connecting structure, the asphalt layer is arranged between the reinforced concrete column and the beam template, so that after the reinforced concrete beam is formed, the asphalt layer is formed between the reinforced concrete beam and the reinforced concrete column; the oil felt layer is arranged on the extending part of the bracket extending out of the side face of the reinforced concrete column, so that the oil felt layer is formed between the extending part of the bracket and the beam, the beam is flexibly connected with the connecting node of the column, and the requirement of seismic fortification under certain specific conditions can be met.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
