Technical Field

[0001] The present invention relates to the technical field of building reinforcement, and in particular to a steel structure building reinforcement method based on prefabricated design. Background Art

[0002] Steel structure building is a new type of building system. It uses construction steel to form the load-bearing structure. It is usually composed of beams, columns, trusses and other components made of steel sections and steel plates. Together with the enclosing structures such as roofs, floors and walls, it forms a complete building.

[0003] At present, in order to reduce costs and facilitate installation, prefabricated buildings mostly use thin-walled columns and thin-walled beams. However, after long-term use, the supporting force of the thin-walled columns will decrease due to various reasons, resulting in a certain degree of bending or deformation, which will affect the strength of the entire building. Therefore, a reinforced structure is needed. However, the current reinforced structure is complex and bulky, and will occupy a large amount of ground area, resulting in the original indoor area being encroached upon, affecting the original activities or material transportation. Summary of the Invention

[0030] S1. First, a connector is set according to the length and width of the cross section of the reinforced column 1. The connector is set on the outside of the reinforced column 1 and fixed to the reinforced beam 2 by bolts;

[0031] S2. Then, external support columns 5 are arranged according to the height between the connecting piece and the ground. The external support columns 5 are distributed around the outside of the reinforced column 1 and are slidably connected to the connecting piece;

[0032] S3. A plurality of locking components for positioning the outer support column 5 are installed in an annular structure on one side of the connecting member. The outer support column 5 is positioned to fit the outer wall surface of the column through the positioning of the locking components;

[0033] S4. The outer support column 5 can be adjusted to move circumferentially according to the situation on site, and after adjustment, it can be placed in close contact with the column again.

[0034] In this embodiment, the connecting member is composed of a first plate 3 and a second plate 4. A positioning opening matching the reinforced column 1 is formed between the first plate 3 and the second plate 4. The connecting member is sleeved on the outside of the reinforced column 1 through the positioning opening. A fixing block 11 is installed at the junction of the first plate 3 and the second plate 4. The fixing block 11 is provided with a fixing hole. A first bolt is inserted into the relative fixing holes, and one end of the first bolt is threadedly connected with a nut.

[0035] In this embodiment, a plurality of fixing seats 15 are installed on the upper surface of the connecting member in a rectangular structure. The fixing seats 15 are each provided with a screw hole, and a second bolt 16 is threadedly connected to the screw hole. One end of the second bolt 16 is in contact with the inner side surface of the upper wing plate of the beam 2.

[0036] In this embodiment, a plurality of connecting grooves 12 are provided on the lower surface of the connecting piece in a rectangular structure. One end of the outer support column 5 is bent to form a connecting portion 13, and the connecting portion 13 is fitted with the connecting piece. A connecting strip 14 is installed on the connecting portion 13, and the connecting strip 14 is slidably provided in the connecting groove 12. The other end of the outer support column 5 is bent to form a first supporting portion 6, and the first supporting portion 6 is provided to contact the base on the reinforced column 1. One end of the first supporting portion 6 is bent to form a second supporting portion 7, and the second supporting portion 7 is provided to contact the ground.

[0037] In this embodiment, the locking components include a vertical rod 8, a rotating seat 17 and a limit plate 10. A plurality of vertical rods 8 are installed in a rectangular structure on the lower surface of the connecting piece. The other end of the vertical rod 8 is installed with a connecting seat 9. The connecting seat 9 is provided with a groove, and a rotating seat 17 is installed in the groove through a pin shaft. A limit plate 10 is installed at one end of the rotating seat 17, and the limit plate 10 is set to contact the outer side surface of the outer support column 5.

[0038] In this embodiment, a plurality of positioning grooves are provided on the open end surface of the first plate 3 , and a plurality of positioning portions are protruded from the open end surface of the second plate 4 , and the positioning portions are inserted into the positioning grooves.

[0039] In this embodiment, the joining end surfaces of the first plate 3 and the second plate 4 are inclined.

[0040] In this embodiment, the connecting piece and the outer support column 5 are both made of steel structure.

[0041] During installation, first understand the length and width of the cross section of the reinforced column on site to design the corresponding connectors, and measure the length between the beam and the ground, then subtract the width of the connector to obtain the length of the outer support column;

[0042] After production is completed, the first plate and the second plate can be sleeved on the outside of the reinforced column, and the connection between the two is completed by the cooperation of the first bolt and the nut, and the positioning part on the first plate can be inserted into the positioning groove of the second plate, thereby increasing the stability between the two after connection;

[0043] Then, the second bolt is threaded into the screw hole. As the second bolt rotates, one end of the second bolt can extend to the inner side of the wing plate of the beam, so that the connecting piece can be fixed on the beam, which facilitates assembly.

[0044] After the above is completed, prepare the outer support column and insert the connecting strip on the outer support column into the connecting groove until it is in fit with the outer surface of the reinforced column. At this time, the rotating limit plate centered on the rotating seat can be moved to the outer side of the outer support column to limit it and avoid loosening caused by displacement of the outer support column.

[0045] Among them, since the outer support column can be installed detachably and fits the reinforced column, and the connected structures are installed on the top, the encroachment on the ground is greatly reduced. Once the installation direction requires passing large materials;

[0046] The limit plate can be lifted upward with the rotating seat as the center. After losing the obstruction of the limit plate, the outer support column can be moved out of the connecting groove and inserted into the connecting groove on the other side to avoid affecting the normal work in the room.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
