Description

Technical Field

[0001] This utility model belongs to the field of steel structure application technology, and specifically relates to a reinforcement structure for load-bearing components of steel structure factory buildings. Background Technology

[0002] Steel structures are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories. However, steel structures will also face the problem of structural component aging after long-term use, so they need to be replaced or reinforced to maintain their structural stability.

[0003] A search revealed a reinforcement structure for load-bearing components of a steel structure factory building, with existing technology announcement number CN 221956935 U. In this scheme, the reinforcement of horizontal and vertical beams is achieved through structures such as first and second support rods. An auxiliary mounting plate is used to fix the plate to the vertical or horizontal beam for locking. This auxiliary mounting plate engages with the bolts via a locking block. The scheme specifies that the width of the auxiliary mounting plate is fixed, thus limiting its applicability to only one type of column width. Furthermore, even if the width of the auxiliary mounting plate could be altered by extending the bolts, the locking effect on the column would be reduced, and the plate would be misaligned during installation, further diminishing the reinforcement effect.

[0004] Therefore, the inventors have provided a more adaptable load-bearing reinforcement structure; Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a reinforcement structure for load-bearing components of steel structure factory buildings. The mounting base can adjust its own width to adapt to columns and beams of different widths. Furthermore, it can be adjusted to be located in the center of the columns and beams to ensure the support effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A reinforcement structure for load-bearing components of a steel structure factory building includes a mounting base and a support arm hinged to the mounting base. Each end of the support arm is provided with a set of mounting bases, which are fixed to the column and the beam by bolts. The mounting base, the support arm, the column, and the beam together form a stable triangular structure, which can improve the structural stability and load-bearing capacity of the column and the beam.

[0008] The mounting base includes an L-shaped plate and a fixed base. A pair of L-shaped plates are symmetrically arranged on both sides of the fixed base, and the L-shaped plates are inserted into the fixed base. The fixed base has an ear plate and a first slot, and also has symmetrically distributed first lead screws. The L-shaped plate is inserted into the first slot, and a fixed plate is provided on the L-shaped plate. The fixed plate has a through hole for inserting the first lead screw. The first lead screw, in conjunction with a nut, ensures that the L-shaped plate fits tightly against the side of the column when inserted into the first slot. The L-shaped plate also has a second slot and a limiting plate. An insert plate is provided in the second slot. The insert plate has a fixed second lead screw and a matching limiting nut. The limiting nut is located inside the limiting plate, and the limiting plate has a through hole for inserting the second lead screw. By rotating the limiting nut on the second lead screw, the insert plate is pushed to slide and contact the web of the column in the second slot, thereby extending and expanding the contact area of ​​the L-shaped plate hooking and locking the column wing plate, increasing friction, and thus improving the hooking and locking effect, making it more secure. The L-shaped plate, in conjunction with the screw, fixes the fixed base to the column.

[0009] The insert plate is provided with a second through groove for inserting the screw for fixing. The second through groove is a prefabricated groove that can adapt to the position of the insert plate in the second slot, reducing the amount of drilling. It can slide and adjust when the screw is inserted into the column and L-shaped plate for support. After adjustment, the nut on the screw can be tightened.

[0010] The L-shaped plate is equipped with pads, which allow the inner side of the L-shaped plate to fit against the wing plate of the column, avoiding gaps that could cause the screw to be unstable when tightening the L-shaped plate and the column due to excessive gaps.

[0011] The support arm includes a sleeve and insert arms that are respectively inserted at both ends of the sleeve. One end of each insert arm is hinged to an ear plate on a fixed base, and the insert arm has a slot. The sleeve has a first through slot, and a partition is between the first through slots. The insert arm is inserted into the first through slot, the slot fits the partition, and the insert arm and sleeve have through holes. A screw passes through the through hole and is fixed to the insert arm and sleeve with a nut. Furthermore, the mutual fit of the insert arm, the first through slot, the slot, and the partition can improve the support strength of the support arm. In particular, the use of the partition provides a reinforcing beam effect in the middle of the sleeve, which improves the situation where the sleeve is set in a conventional square frame form, resulting in insufficient support strength in the middle.

[0012] The socket is equipped with a mounting plate, and the mounting plate is equipped with a screw. The other end of the screw is fixed to the column and the crossbeam by a nut to provide tension and improve the support strength of the support arm.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] This solution uses a detachable mounting base fixed to a column or beam. The beam and column are H-beams, which can adapt to the width of the column or beam through the insertion of the L-shaped plate and the mounting base, thus improving the adaptability of the mounting base. Secondly, the L-shaped plate is equipped with an insert plate, which can be controlled to fit tightly against the web and flange of the H-beam through the cooperation of the second screw and nut. This increases the hooking and snapping area between the L-shaped plate and the H-beam, and also increases the friction effect, thus improving the connection and fixing effect between the mounting base and the H-beam.

[0015] Secondly, the support arm can be length adjusted, and the connection method between the insert arm and the insert sleeve, as well as the application of the partition plate in the insert sleeve, can improve the situation where the intermediate support strength is insufficient due to the conventional square frame shape of the insert sleeve.

[0026] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-9 The technical solution of this utility model will be further described in detail below.

[0027] A reinforcement structure for load-bearing components of a steel structure factory building includes a mounting base 1 and a support arm 2 hinged to the mounting base 1. Each end of the support arm 2 is provided with a set of mounting bases 1. The mounting bases 1 are fixed to the column 9 and the beam 8 by bolts. The mounting base 1, the support arm 2 and the column 9 and the beam 8 form a stable triangular structure, which can improve the structural stability and load-bearing capacity of the column 9 and the beam 8.

[0028] The mounting base 1 includes an L-shaped plate 6 and a fixing base 5. A pair of L-shaped plates 6 are symmetrically arranged on both sides of the fixing base 5, and the L-shaped plates 6 are inserted into the fixing base 5. The fixing base 5 has an ear plate 51 and a first slot 53, and also has symmetrically distributed first lead screws 52. The L-shaped plate 6 is inserted into the first slot 53. The L-shaped plate 6 has a fixing plate 61, which has a through hole for inserting the first lead screws 52. The first lead screws 52, in conjunction with a nut, ensure that the L-shaped plate 6 is tightly against the side of the column 9 when inserted into the first slot 53. The L-shaped plate 6 also has a second slot 63 and a limiting device. Plate 62, the second slot 63 is provided with an insert plate 7; the insert plate 7 is provided with a fixed second lead screw 71 and a matching limiting nut 72. The limiting nut 72 is located inside the limiting plate 62. The limiting plate 62 is provided with a through hole for inserting the second lead screw 71. By rotating the limiting nut 72 on the second lead screw 71, the insert plate 7 is pushed to slide and contact the web plate of the column 9 in the second slot 63, thereby extending and expanding the contact area of ​​the L-shaped plate 6 hooking and locking the wing plate of the column 9, increasing friction, thereby improving the hooking and locking effect and making it more secure; the L-shaped plate 6, together with the screw 4, fixes the fixing seat 5 on the column 9.

[0029] The insert plate 7 is provided with a second through groove 73 for inserting the screw 4 for fixing. The second through groove 73 is a prefabricated groove that can adapt to the position of the insert plate 7 in the second slot 63, reducing the amount of drilling. It can slide and adjust when the screw 4 is inserted into the column 9 and the L-shaped plate 6 for support. After the adjustment is completed, the nut on the screw 4 can be tightened.

[0030] The L-shaped plate 6 is provided with a pad 64, which allows the inner side of the L-shaped plate 6 to fit against the wing plate of the column 9, avoiding gaps that would cause the screw 4 to be unstable when tightening the L-shaped plate 6 and the column 9 due to excessive gaps.

[0031] The support arm 2 includes a sleeve 21 and insert arms 22 that are respectively inserted at both ends of the sleeve 21. One end of the insert arm 22 is hinged to the ear plate 51 on the fixing seat 5. The insert arm 22 is provided with a slot 221. The sleeve 21 is provided with a first through slot 211, and a partition 212 is between the first through slots 211. The insert arm 22 is inserted into the first through slot 211, and the slot 221 fits into the partition 212. The insert arm 22 and the sleeve 21 are provided with through holes. The insert arm 22 and the sleeve 21 are fixed by passing a screw 4 through the through hole and cooperating with a nut. Furthermore, the mutual fit of the insert arm 22, the first through slot 211, the slot 221 and the partition 212 can improve the support strength of the support arm 2. In particular, the use of the partition 212 provides a reinforcing beam effect in the middle of the sleeve 21, which improves the situation where the sleeve 21 is set in a conventional square frame form and the middle support strength is insufficient.

[0032] The insert 21 is provided with an mounting plate 3, and the mounting plate 3 is provided with a screw 4. The other end of the screw 4 is fixed to the column 9 and the crossbeam 8 by a nut to provide tension and improve the support strength of the support arm 2.

[0033] During installation, the column 9 and the crossbeam 8 are fixedly connected. Both are H-shaped steel, and the crossbeam 8 bears the load. The mounting base 1 fixes the L-shaped plate 6 to the column 9 or the crossbeam 8 through the screw 4. When fixing the mounting base 1, first fix one set of mounting bases 1, and then adjust the length of the support arm 2 according to the position of the other set of mounting bases 1, that is, adjust the depth of the insertion of the insert arm 22 into the insert sleeve 21. Then, after the length of the support arm 2 is adjusted, the second set of mounting bases 1 is installed.

[0034] During the installation of mounting base 1, L-shaped plate 6 is inserted into the first slot 53 on the fixing base 5, and then the nut on the first screw 52 is tightened to restrict its movement. Then, screw 4 is inserted to support L-shaped plate 6 with column 9 or crossbeam 8. Then, by rotating the limiting nut 72 on the second screw 71, the insert plate 7 touches the web of column 9 or crossbeam 8. Then, the nut on screw 4 is tightened to complete the locking and fixing.

[0035] The L-shaped plate 6 slides within the first slot 53 and is restricted by the first lead screw 52 to prevent it from slipping out of the first slot 53, thus adapting to columns 9 or beams 8 of different widths. It is worth noting that the through holes of the corresponding screws 4, the first lead screw 52, ​​and the second lead screw 71 on the columns 9 and beams 8 are either pre-drilled or drilled in real time during installation. One or two methods can be selected and used in combination depending on the on-site construction environment.
