Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to an assembled steel structure support beam. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representatives of modern industrialized production methods because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications.

[0003] For example, the authorization announcement number, CN 208685797 U, discloses a support beam for an assembled steel structure building, whose structure includes a gasket and a support device. The utility model is a support beam for an assembled steel structure building. By providing a support device, a T-shaped support plate is installed at the lower end of the connection between the transverse frame beam and the frame column, and then fixed together by a friction-type high-strength bolt. The support rod makes the transverse frame beam and the frame column form a triangular support structure, which greatly increases the strength of the support beam and solves the problem that the support beam in the prior art has low strength and is easy to deform, resulting in poor building stability. By providing a friction-type high-strength bolt and tightening the nut with a special wrench, the screw rod generates a huge and controlled pre-tension, and the same amount of pre-pressure is also generated on the side gasket through the nut and the annular gasket. Under the action of the pre-pressure, the component will not slip and the connection will not be damaged, solving the problem that the shear resistance of the bolts in the prior art is poor and the bolts are easy to break.

[0004] At present, no supporting mechanism is set on the support columns in prefabricated steel structures. When the support beam is lifted by a crane and connected and fixed to the support column, the support beam needs to be kept in a lifted state. Since the lifting of the support beam by the crane is not stable, it is easy to affect the connection between the support beam and the support column. Therefore, the market urgently needs to develop an assembled steel structure support beam to help people solve the existing problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a prefabricated steel structure support beam to solve the problem raised in the above-mentioned background technology that no support mechanism is provided on the support column in the current prefabricated steel structure. When the support beam is lifted by a crane and connected and fixed to the support column, it is necessary to maintain the lifting state of the support beam. Since the lifting of the support beam by the crane is not stable, it is easy to affect the problem of the connection between the support beam and the support column.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an assembled steel structure support beam, comprising an H-shaped steel column, an H-shaped support member fixedly provided on the H-shaped steel column, a first support plate fixedly connected to the front and rear ends of the upper end of the H-shaped support member, a second support plate fixedly connected to both sides of the upper end of the H-shaped support member, a first H-shaped support steel beam connected to the upper ends of the two first support plates and at the front and rear ends of the H-shaped support member, and a second H-shaped support steel beam connected to the upper ends of the two second support plates and at both sides of the H-shaped support member.

[0007] Preferably, an H-shaped slot is provided inside the H-shaped support member, and the upper end of the H-shaped steel column passes through the H-shaped slot inside the H-shaped support member.

[0008] Preferably, the H-shaped steel column and the H-shaped support member are fixedly connected by a plurality of first bolts.

[0009] Preferably, the upper surfaces of the first support plate and the second support plate are fixedly connected to the limiting edge strips on the outer sides of the first H-shaped support steel beam and the second H-shaped support steel beam respectively.

[0010] Preferably, a triangular shear support plate is fixedly connected between the middle portion of the lower end surface of the first support plate and the second support plate and the outer end surface of the H-shaped support member.

[0011] Preferably, the first H-shaped support steel beam and the H-shaped steel column are fixedly connected by a first L-shaped connecting plate, the first H-shaped support steel beam and the first L-shaped connecting plate are fixed by welding, and the first L-shaped connecting plate and the H-shaped steel column are fixedly connected by a second bolt.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the utility model, by setting the H-shaped support member, the H-shaped steel column and the H-shaped support member are fixedly connected by multiple first bolts, so that the H-shaped support member is stably fixed on the H-shaped steel column. When the first H-shaped support steel beam and the second H-shaped support steel beam are hoisted, the first support plate and the second support plate of the H-shaped support member on the two H-shaped steel columns are respectively supported at both ends of the first H-shaped support steel beam and the second H-shaped support steel beam, so that the first H-shaped support steel beam and the second H-shaped support steel beam can remain stable when the hoist device is installed, without the need for a crane to provide support force. The crane provides partial pulling force after hoisting, thereby ensuring the stability of the installation operation of the first H-shaped support steel beam and the second H-shaped support steel beam, thereby improving construction safety.

In this utility model, through the arrangement of triangular shear support plates, triangular shear support plates are fixedly connected between the middle parts of the lower end surfaces of the first support plate and the second support plate and the outer end surfaces of the H-shaped support member. The bottoms of the first support plate and the second support plate are supported by multiple triangular shear support plates to prevent the first support plate and the second support plate from bending after being compressed, thereby improving the structural stability of the first support plate and the second support plate.

[0016] 3. In the utility model, through the setting of limiting edge strips, the upper end surfaces of the first support plate and the second support plate are fixedly connected to the outer sides of the first H-shaped support steel beam and the second H-shaped support steel beam respectively. The limiting edge strips are used to limit the outer sides of the first H-shaped support steel beam and the second H-shaped support steel beam on the first support plate and the second support plate to prevent one end of the first H-shaped support steel beam and the second H-shaped support steel beam from sliding on the first support plate and the second support plate, thereby ensuring the stability of the first H-shaped support steel beam and the second H-shaped support steel beam during fixed operation.
