Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, specifically a modular building steel structure that is easy to assemble and disassemble. Background Technology

[0002] Steel structure is a type of structure made of steel materials. It is one of the main types of building structures. This structure is usually composed of components such as steel beams, steel columns, and steel trusses made of materials such as steel sections and steel plates. The components are usually connected by welds, bolts, or rivets. Steel structures are widely used in buildings, factories, bridges and other fields because of their characteristics such as light weight, high strength, fast construction speed, environmental protection and energy saving, and reusability.

[0003] Regarding easily assembled and disassembled modular steel structures, a search revealed a type of steel frame structure (publication number: CN222575745U). This structure involves horizontally pushing a tie rod, inserting a connector into the connector channel to limit the vertical position of the tie rod. Because the wall of the anti-push rod has an inclined surface, during horizontal movement, the connector pushes the inclined surface of the anti-push rod, causing it to move upwards within the vertical groove. When the anti-push rod reaches the positioning groove directly opposite the top of the connector, it falls into the positioning groove, thus limiting the horizontal position of the connector. This effectively prevents the tie rod from detaching after it is inserted into the locking block, resulting in higher installation stability. Simultaneously, the tie rod supports the steel frame body, improving the overall strength and load-bearing capacity of the steel frame. However, the steel structure shed still has shortcomings in actual use. The main frame of the steel structure shed is welded as one piece, which is not convenient to disassemble and assemble. It occupies too much space during transportation, resulting in a smaller loading capacity. In addition, the one-piece frame is also more time-consuming and labor-intensive during loading and unloading. Utility Model Content

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] The present application will be described in detail below with reference to the drawings and specific embodiments.

[0026] Embodiments

[0027] As Figures 1-7As shown, a modular steel structure for easy assembly and disassembly includes: a steel frame 1, multiple support columns 101 installed at the bottom of the steel frame 1, bases 102 welded to the bottom of the multiple support columns 101, an installation assembly disposed between the steel frame 1 and the multiple support columns 101, the installation assembly including: an installation cavity 2, through holes a 201 and b 202, an installation screw 203, a washer 204 and a fixing nut 205, and a reinforcement assembly disposed between the multiple bases 102, the reinforcement assembly including: a reinforcement rod 3, an installation bracket 301, an installation screw hole 302 and a limiting screw hole 303.

[0028] The steel structure frame 1 has an installation cavity 2 inside. The bottom two sides of the steel structure frame 1 have through holes a201 communicating with the installation cavity 2. The top two sides of the support column 101 have through holes b202. The support column 101 has a hollow structure inside. The installation screws 203 are inserted into the through holes a201 and b202. The outer end of the installation screws 203 is provided with a washer 204. The outer side of the washer 204 is provided with a fixing nut 205.

[0029] When using the steel structure frame 1, lift it up and place it on the support column 101, so that the support column 101 is inserted into the mounting cavity 2. The mounting cavity 2 is a circular structure, that is, the support column 101 and the mounting cavity 2 fit together and are fixed in place. Then, the steel structure frame 1 is positioned and supported by the limiting block 206. At this time, the through holes a201 on both sides of the bottom of the steel structure frame 1 are aligned with the through holes b202 on both sides of the top of the support column 101. The mounting screw 203 is inserted from the through hole a on the outer side. Insert the screw 201 and through hole b202, and pass through through hole b202 and through hole a201 on the other side, so that the mounting screw 203 protrudes from the outside of the steel structure frame 1. Put the washer 204 on the protruding end of the mounting screw 203, screw the fixing nut 205 into the mounting screw 203, and tighten the fixing nut 205 so that the washer 204 and the fixing nut 205 are in close contact with the outside of the steel structure frame 1, thereby fixing the steel structure frame 1 and the support column 101 together for use.

[0030] When transporting the steel structure frame 1, loosen the fixing nut 205 from the mounting screw 203, remove the fixing nut 205 and washer 204, and pull the mounting screw 203 out from the through hole a201 and through hole b202. Release the steel structure frame 1 from the support column 101, and then the steel structure frame 1 and the support column 101 can be separated. That is, the steel structure frame 1 is a single unit, and the support column 101 and the base 102 are a single unit. When placed on the transport vehicle, they can be placed side by side to avoid occupying too much placement space. After disassembly, the steel structure frame 1 and the support column 101 are separate units, which is convenient for loading and unloading, achieving the purpose of saving time and effort.

[0031] Among them, the top of the support column 101 is welded with a limiting block 206, and the bottom of the steel structure frame 1 is closely fitted with the limiting block 206. When the steel structure frame 1 is installed with the support column 101, the steel structure frame 1 is placed on the support column 101 and can be supported by the limiting block 206. During the installation process, it is ensured that the steel structure frame 1 is placed stably.

[0032] The bottom of the limiting block 206 is welded with multiple reinforcing ribs 207 arranged in a ring. When the limiting block 206 is in use, the bottom of the limiting block 206 is welded with multiple reinforcing ribs 207, and the bottom ends of the multiple reinforcing ribs 207 are welded and fixed to the base 102. The multiple reinforcing ribs 207 increase the stress points at the bottom of the limiting block 206. The ring arrangement of the multiple reinforcing ribs 207 can distribute the gravity on the limiting block 206, prevent the limiting block 206 from deforming after being stressed, and thus provide stable support for the steel structure frame 1.

[0033] Multiple bases 102 are fixed with fixing brackets 4 on both sides of their outer ends by bolts. Each fixing bracket 4 has a fixing hole 401 at its bottom. After the steel structure frame 1 and the support column 101 are installed and fixed, when it is necessary to fix the base 102, first use a handheld drill to drill holes in the ground of the installation area. When drilling, insert the drill rod of the handheld drill into the fixing hole 401 and make it contact the ground. Then start the handheld drill to drive the drill rod to rotate and complete the drilling in the ground. Ensure that the hole in the ground can be aligned with the fixing hole 401 at the bottom of the fixing bracket 4. At this time, insert the expansion bolt into the fixing hole 401 and the hole. When tightening the bolt, the nut or special expansion sleeve at the tail of the expansion bolt will start to expand, thereby generating pressure in the hole. This pressure will cause the tail of the expansion bolt to expand and fit tightly into the hole in the ground, thereby fixing the base 102 to the ground and ensuring that the entire frame is used firmly and preventing it from tipping over during use.

[0034] The top of the steel structure frame 1 is fixedly installed with a top beam frame 5 by bolts. The top of the top beam frame 5 has a limit groove 501. Before the steel structure frame 1 and the support column 101 are installed, the steel structure frame 1 is first laid upside down, and the top beam frame 5 is aligned with the two sides of the top of the steel structure frame 1 so that the holes between the top beam frame 5 and the steel structure frame 1 are aligned. Then, the bolts are tightened in the holes of the top beam frame 5 and the steel structure frame 1 to fix the top beam frame 5 on the steel structure frame 1. After the top beam frame 5 is fixed, the steel structure frame 1 is erected, and then the steel structure frame 1 is connected and installed with the support column 101 so that the steel structure frame 1, the support column 101, the base 102 and the top beam frame 5 are used as a whole after the parts and nodes are installed and fixed.

[0035] When using the top beam frame 5, the top limiting groove 501 of the top beam frame 5 has screw holes. The limiting groove 501 can be used to install the crossbeam of the scaffold. The crossbeam can be built between two top beam frames 5. The crossbeam is placed into the limiting groove 501, and the screw holes on the crossbeam are aligned with the screw holes in the limiting groove 501. The crossbeam can be fixed by screwing the bolts into the screw holes and tightening them.

[0036] This application only shows one steel structure frame 1 and top beam frame 5. In reality, the scaffolding has two or more steel structure frames 1 and top beam frames 5. When building the scaffolding, prepare several pre-installed steel structure frames 1, support columns 101, bases 102 and top beam frames 5 and place them side by side at intervals in the installation area, and then fix them.

[0037] Among them, a reinforcing rod 3 is installed between multiple bases 102. The outer ends of the reinforcing rod 3 are fixed with mounting brackets 301 by bolts. The outer sides of the mounting brackets 301 are provided with mounting screw holes 302. The outer ends of multiple bases 102 are provided with limit screw holes 303.

[0038] When the base 102 and support column 101 support the steel structure frame 1, the reinforcing rod 3 is installed between multiple bases 102. That is, the mounting brackets 301 on both sides of the outer end of the reinforcing rod 3 are tightly attached to the outer sides of the base 102. At this time, the mounting screw holes 302 on the outer side of the mounting brackets 301 are aligned with the limiting screw holes 303 on both sides of the outer end of the base 102. Bolts are screwed into the mounting screw holes 302 and the limiting screw holes 303 and tightened, thereby fixing the reinforcing rod 3 between multiple bases 102. This can increase the stress support of the base 102, and the reinforcing rod 3 can be flexibly disassembled and assembled with the base 102 for convenient use.

[0039] Working principle:

[0040] Before installing the steel structure frame 1 and the support column 101, first invert the steel structure frame 1 and align the top beam frame 5 with the two sides of the top of the steel structure frame 1, so that the holes between the top beam frame 5 and the steel structure frame 1 are aligned. Then, tighten the bolts into the holes of the top beam frame 5 and the steel structure frame 1 to fix the top beam frame 5 on the steel structure frame 1. After fixing the top beam frame 5, stand the steel structure frame 1 upright and then lift the steel structure frame 1 and place it on the support column 101, so that the support column 101 is inserted into the installation cavity 2. The installation cavity 2 is a circular structure, that is, the support column 101 and the installation cavity 2 fit together and are inserted and fixed. Then, the limiting block 206 limits and supports the placement of the steel structure frame 1. At this point, the through holes a201 on both sides of the bottom of the steel structure frame 1 are aligned with the through holes b202 on both sides of the top of the support column 101. The mounting screw 203 is inserted from the through holes a201 and b202 on one side of the outer end and passes through the through holes b202 and a201 on the other side, so that the mounting screw 203 protrudes from the outside of the steel structure frame 1. The washer 204 is put on the protruding end of the mounting screw 203, and the fixing nut 205 is screwed into the mounting screw 203 and tightened, so that the washer 204 and the fixing nut 205 are tightly attached to the outside of the steel structure frame 1, thereby fixing the steel structure frame 1 and the support column 101 together for use.

[0041] When transporting the steel structure frame 1, loosen the fixing nut 205 from the mounting screw 203, remove the fixing nut 205 and washer 204, and pull the mounting screw 203 out from the through hole a201 and through hole b202. Release the steel structure frame 1 from the support column 101, and then the steel structure frame 1 and the support column 101 can be separated. That is, the steel structure frame 1 is a single unit, and the support column 101 and the base 102 are a single unit. When placed on the transport vehicle, they can be placed side by side to avoid occupying too much placement space. After disassembly, the steel structure frame 1 and the support column 101 are separate units, which is convenient for loading and unloading, achieving the purpose of saving time and effort.

[0042] When the base 102 and support column 101 support the steel structure frame 1, the reinforcing rod 3 is installed between multiple bases 102. That is, the mounting brackets 301 on both sides of the outer end of the reinforcing rod 3 are tightly attached to the outer sides of the base 102. At this time, the mounting screw holes 302 on the outer side of the mounting brackets 301 are aligned with the limiting screw holes 303 on both sides of the outer end of the base 102. Bolts are screwed into the mounting screw holes 302 and the limiting screw holes 303 and tightened, thereby fixing the reinforcing rod 3 between multiple bases 102. This can increase the stress support of the base 102, and the reinforcing rod 3 can be flexibly disassembled and assembled with the base 102 for convenient use.
