Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure buildings, and in particular relates to an assembled steel structure building support device for green buildings. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel and steel plates. It uses silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Prefabricated steel structures generally use bolts to connect nodes.

[0003] In existing steel structure buildings, the connection nodes between beams and columns are generally connected using multiple bolts. In order to improve the connection strength of the nodes, diagonal bracing mechanisms such as reinforcing ribs are generally provided to improve the supporting effect of the columns on the beams. However, the above-mentioned diagonal bracing structure does not have a buffering effect; when the beam is subjected to a large impact, such as a heavy object falling from the steel platform on the beam, the beam will produce elastic deformation, which will cause the beam to be subjected to concentrated force at the stress point of the reinforcing ribs, increasing the possibility of fracture; and when the deformation of the beam exceeds the elastic deformation range and cracks are generated, some cracks cannot be observed by the staff in time, thus causing a large safety hazard. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide an assembled steel structure building support device for green buildings, so as to solve the problem that in existing steel structure buildings, the connection nodes between beams and columns lack a support mechanism with a buffering and protective function, which causes the beams to break easily after being subjected to force, and the cracks may not be observed in time by the staff.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: an assembled steel structure building support device for green buildings, including a steel column, a connecting end plate welded to the top of the steel column, the connecting end plate is connected to a steel beam by connecting bolts, and a mounting seat is provided on the bottom surface of the connecting end plate, the mounting seat is sleeved with one end of the warning member, and the other end of the warning member rests on an elastic buffer member, the warning member includes an outer tube body, an inner tube body is installed inside the outer tube body, the interior of the inner tube body is filled with potassium iodide solution, and the interior of the outer tube body outside the inner tube body is filled with starch solution, the elastic buffer member is an arc plate structure, and the two ends of the elastic buffer member are respectively clamped in positioning member one and positioning member two, and the positioning member one and positioning member two are respectively mounted on the side of the steel column and the bottom surface of the steel beam by bolts.

[0006] The beneficial effects of the utility model are as follows: the elastic buffer cooperates with the connecting end plate to provide triangular support for the steel beam under normal conditions to ensure the structural stability of the steel beam; when the steel beam is subjected to force and produces downward elastic deformation, the elastic buffer produces elastic deformation to play the role of buffering and supporting the steel beam; when the elastic buffer is deformed, the warning piece is squeezed and produces a chemical color change reaction, thereby reminding the staff to promptly check whether there are cracks on the surface of the steel beam.

[0007] In order to effectively ensure the installation stability of the elastic buffer;

[0008] As a further improvement of the above technical solution: the positioning member 1 and the positioning member 2 have the same structure, the positioning member 1 includes a connecting plate and a positioning plate, the positioning plate is welded to one side of the connecting plate, and the positioning plate is provided with a positioning groove adapted to plug in one end of the elastic buffer.

[0009] The beneficial effect of this improvement is that the two ends of the elastic buffer can be clamped in the positioning grooves provided in the positioning member 1 and the positioning member 2, which effectively ensures the stability of the installation of the elastic buffer and avoids affecting the elastic deformation of the elastic buffer.

[0010] In order to ensure the stability of the installation of positioning piece 1 and positioning piece 2 on the steel column and steel beam;

[0011] As a further improvement of the above technical solution: a plurality of positioning holes for inserting bolts are provided on the connecting plate.

[0012] The beneficial effect of this improvement is that the positioning member 1 and the positioning member 2 can be stably installed on the steel column and the steel beam by means of multiple sets of bolts, thereby ensuring the stability of the installation.

[0013] In order to ensure that the first and second positioning members provide stable support to the elastic buffer member;

[0014] As a further improvement of the above technical solution: the connecting plate is an angle iron structure.

[0015] The beneficial effect of this improvement is that after one side of the connecting plate is installed in contact with the steel column and the steel beam, the other side of the connecting plate can stably support the elastic buffer.

[0016] In order to ensure the stability of the warning installation;

[0017] As a further improvement of the above technical solution: the mounting seat is welded obliquely to the bottom surface of the connecting end plate, and the mounting seat is a round tube structure.

[0018] The beneficial effect of this improvement is that the mounting seat can provide mounting support for the warning member, limit the angle and top position of the warning member, so that the other end of the warning member can stably rest against the elastic buffer member when the elastic buffer member is elastically deformed.

[0019] In order to effectively ensure the stability of the use of warning parts;

[0020] As a further improvement of the above technical solution: the inner tube body is a translucent glass tube structure.

[0021] The beneficial effect of this improvement is that after the warning piece is squeezed, the potassium iodide solution reliably stored in the inner tube body overflows as the inner tube body breaks and mixes with the starch solution, thereby reacting and converting to a blue-black color, so that the staff can intuitively judge whether the steel beam has undergone a large deformation that is prone to cracking by observing the color of the warning piece.

[0022] In order to ensure the stability of the connection between the end plate and the steel beam;

[0023] As a further improvement of the above technical solution: a plurality of through-hole structures adapted to insert connecting bolts are provided on the connecting end plates and the lower flanges of the steel cross beams.

[0024] The beneficial effect of this improvement is that a plurality of connecting bolts can firmly connect the steel cross beam and the connecting end plate.

[0025] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

The elastic buffer 7 is an arc-shaped plate structure. The two ends of the elastic buffer 7 are respectively clamped in the positioning member 1 8 and the positioning member 2 9. The positioning member 1 8 and the positioning member 2 9 are respectively installed on the side of the steel column 1 and the bottom of the steel beam 2 by bolts. The elastic buffer 7 cooperates with the connecting end plate 3 to provide a triangular support for the steel beam 2 to ensure the structural stability of the steel beam 2. When the steel beam 2 is subjected to force and produces downward elastic deformation, the elastic buffer 7 produces elastic deformation to play the role of buffering and supporting the steel beam 2.When the elastic buffer 7 is deformed, the warning member 6 is squeezed and produces a chemical color change reaction, thereby reminding the staff to promptly check whether there are cracks on the surface of the steel beam 2. The positioning member 1 8 and the positioning member 2 9 have the same structure. The positioning member 1 8 includes a connecting plate 81 and a positioning plate 82. The positioning plate 82 is welded to one side of the connecting plate 81. A positioning groove 84 is provided on the positioning plate 82 to fit one end of the elastic buffer 7. The two ends of the elastic buffer 7 can be clamped in the positioning grooves 84 provided in the positioning member 1 8 and the positioning member 2 9, which effectively ensures the stability of the installation of the elastic buffer 7 and avoids affecting the elastic deformation of the elastic buffer 7. A plurality of positioning holes 83 for inserting bolts are provided on the connecting plate 81. The positioning member 1 8 and the positioning member 2 9 can be firmly installed on the steel column 1 and the steel beam 2 by multiple sets of bolts to ensure the stability of the installation. The connecting plate 81 is an angle iron structure. After one side of the connecting plate 81 is fitted against the steel column 1 and the steel beam 2 for installation, The other side of the connecting plate 81 can stably support the elastic buffer 7. The mounting seat 5 is welded obliquely on the bottom surface of the connecting end plate 3. The mounting seat 5 is a round tube structure. The mounting seat 5 can provide mounting support for the warning member 6, limit the angle and top position of the warning member 6, so that the other end of the warning member 6 can stably rest on the elastic buffer 7 when the elastic buffer 7 is elastically deformed. The inner tube body 62 is a translucent glass tube structure. After the warning member 6 is squeezed, the potassium iodide solution 64 reliably stored in the inner tube body 62 overflows and mixes with the starch solution 63 as the inner tube body 62 is broken, so that the reaction is converted into blue-black, so that the staff can intuitively judge whether the steel beam 2 has a large deformation that is easy to crack by observing the color of the warning member 6. The connecting end plate 3 and the lower flange of the steel beam 2 are provided with a plurality of through-hole structures adapted to insert the connecting bolts 4. The plurality of connecting bolts 4 can stably connect the steel beam 2 with the connecting end plate 3. ;

At this time, the warning piece 6 is squeezed by the elastic buffer 7, and the inner tube body 62 in the warning piece 6 is broken, so that the potassium iodide solution 64 overflows and mixes with the starch solution 63, thereby producing a color change reaction, so that the solution in the warning piece 6 gradually changes from colorless to blue-black.
