Description

Technical Field

[0001] This utility model relates to the construction technology of building firewalls, and in particular to a reinforcement node structure for ultra-high lightweight firewalls. Background Technology

[0002] Firewalls are crucial partitioning components that separate horizontal fire compartments or prevent the spread of fire between buildings. Therefore, firewalls should possess sufficient stability and resistance to minimize fire damage. Due to the significant weight of masonry firewalls, lightweight steel frame firewalls are generally used in steel structure factories or public buildings.

[0003] Lightweight steel keel fire walls use a light steel keel as the framework, with fire-resistant boards such as fiber-reinforced calcium silicate board / silicate board, gypsum board, low-shrinkage fiber cement pressure board, or glass fiber mesh reinforced cement board as the surface layer, and are filled with rock wool to meet the fire resistance limit requirements of building fire protection design codes. However, due to the relatively low strength and rigidity of light steel keels, their usable floor height is limited to below 6.0m. For large-space buildings such as large stadiums and industrial plants with floor heights exceeding 6.0m, it is necessary to add steel sections (such as square steel) or steel pipes (such as square tubes) at certain intervals according to structural calculations to reinforce and enhance the structural stability of the light steel keel system. Depending on the applicable scenario, this can be defined as an ultra-high lightweight fire wall.

[0004] In the construction of ultra-high lightweight firewalls, square steel or square tubing serves as a crucial load-bearing and supporting structure, and the stability and reliability of its node connections directly affect the safety and quality of the entire project. Steel structure connection methods can be divided into welding and fastener connections. Currently, welding is the most common method used for connecting reinforcement nodes during the construction of ultra-high lightweight firewalls. Welding can effectively reduce gaps at the joints, strengthen the connection, and increase the overall stability of the structure. However, it also has drawbacks such as increasing the load on the roof steel beams, compromising the load-bearing capacity of the roof steel beams, and difficulty in ensuring welding quality at high altitudes or in confined spaces. Therefore, we propose a new connection method for reinforcement nodes in ultra-high lightweight firewalls. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an ultra-high lightweight firewall reinforcement node structure, which solves the problems of current firewall node structures increasing the load on roof steel beams, damaging the bearing capacity of roof steel beams, and making it difficult to guarantee the welding quality at high altitudes or in confined spaces.

[0006] To solve the above-mentioned technical problems, this utility model provides: an ultra-high lightweight firewall reinforcement node structure, including a longitudinal square tube and a transverse square tube. The longitudinal square tube is connected to the top beam through a top node assembly, and the joint between the longitudinal square tube and the transverse square tube is connected through a middle node assembly. The top node assembly includes two sets of angle steel, which are arranged on both sides inside the longitudinal square tube. The angle steel is connected to the upper bearing part through a first locking bolt. A first snap-fit ​​part is also provided on one side of the upper bearing part, which snaps onto one side of the top beam. The other side of the upper bearing part is also connected to a second snap-fit ​​assembly, which snaps onto and fixes the other side of the top beam.

[0007] Preferably, the second snap-fit ​​assembly includes a second snap-fit ​​portion, which snaps onto the other side of the top beam, enabling the second snap-fit ​​assembly to be snapped and fixed to the other side of the top beam.

[0008] Preferably, a first connecting part is also provided on one side of the upper bearing part. The first connecting part and the second connecting part are arranged in parallel. The second connecting part is provided on one side of the second snap-fit ​​part, so that the upper bearing part and the second snap-fit ​​part can be connected in parallel.

[0009] Preferably, the first snap-fit ​​portion and the second snap-fit ​​portion are connected by a second locking bolt, which can lock and fix the upper bearing portion and the second snap-fit ​​portion.

[0010] Preferably, the central node assembly includes a central steel frame, on which first connecting frames are symmetrically arranged, the first connecting frames being used to connect two sets of longitudinal square tubes.

[0011] Preferably, a second connecting frame is symmetrically arranged on both sides of the central steel frame, and the second connecting frame is used to connect the two sets of transverse square tubes.

[0012] Preferably, a top keel is provided at the top of the longitudinal square tube, and a ground keel is provided at the bottom of the longitudinal square tube, which improves the overall load-bearing strength of the top and bottom of the longitudinal square tube.

[0013] Preferably, multiple sets of vertical light steel keels are provided between the top surface keel and the horizontal square tube, and multiple sets of horizontal light steel keels are provided between the vertical light steel keels, which improves the mechanical strength of the entire wall.

[0014] The beneficial effects of this utility model are:

[0024] Example 1

[0025] Please see Figure 1-4A reinforced node structure for an ultra-lightweight firewall includes a longitudinal square tube 2 and a transverse square tube 6. The longitudinal square tube 2 is connected to a top beam 9 via a top node assembly 1, and the joint between the longitudinal square tube 2 and the transverse square tube 6 is connected via a middle node assembly 7. The top node assembly 1 includes two sets of angle steels 15, which are disposed on both sides inside the longitudinal square tube 2. The angle steels 15 are connected to an upper bearing part 13 via a first locking bolt 12. A first snap-fit ​​part 11 is also provided on one side of the upper bearing part 13, which snaps onto one side of the top beam 9. The other side of the upper bearing part 13 is also connected to a second snap-fit ​​assembly, which is connected to the top beam 9. The other side of the beam 9 is snapped and fixed; the second snap-fit ​​assembly includes a second snap-fit ​​part 16, which snaps onto the other side of the top beam 9, enabling the second snap-fit ​​assembly to be snapped and fixed to the other side of the top beam 9. A first connecting part 17 is also provided on one side of the upper bearing part 13. The first connecting part 17 and the second connecting part 18 are arranged in parallel. The second connecting part 18 is provided on one side of the second snap-fit ​​part 16, enabling the upper bearing part 13 and the second snap-fit ​​part 16 to be connected in parallel. The first snap-fit ​​part 11 and the second snap-fit ​​part 16 are connected by a second locking bolt 14, which can lock and fix the upper bearing part 13 and the second snap-fit ​​part 16.

[0026] First, the first snap-fit ​​part 11 is snapped onto one side of the top beam 9, and the second snap-fit ​​part 16 is snapped onto the other side of the top beam 9. The first connecting part 17 and the second connecting part 18 are then fitted together. The first connecting part 17 and the second connecting part 18 are locked and fixed by the second locking bolt 14. Then, the angle steel 15 on the longitudinal square tube 2 is fitted together with the upper bearing part 13. The angle steel 15 is then fixed to the upper bearing part 13 by the first locking bolt 12. This allows for a quick connection and fixation between the longitudinal square tube 2 and the top beam 9 without altering the overall shape of the top beam 9 or damaging its main structure. This ensures the load-bearing capacity of the top beam 9, facilitates installation, requires welding, and can be installed even in small spaces.

[0027] In this application, the upper support portion 13, the first snap-fit ​​portion 11, and the first connecting portion 17 are integrally formed structures, and the second snap-fit ​​portion and the second connecting portion 18 are integrally formed structures.

[0028] Please see Figure 5 The central node component 7 includes a central steel frame 71, on which a first connecting frame 72 is symmetrically arranged. The first connecting frame 72 is used to connect two sets of longitudinal square tubes 2. On the other two sides of the central steel frame 71, a second connecting frame 73 is symmetrically arranged. The second connecting frame 73 is used to connect two sets of transverse square tubes 6.

[0029] When connecting the horizontal square tube 6 and the vertical square tube 2, the vertical square tubes 2 on the upper and lower sides are snapped onto the first connecting frame 72, and the horizontal square tubes 6 on the left and right sides are snapped onto the second connecting frame 73, thus completing the connection between the horizontal square tube 6 and the vertical square tube 2. The assembly and installation are convenient, and the overall load-bearing capacity of the connection is strong.

[0030] Furthermore, a top keel 3 is installed at the top of the longitudinal square tube 2, and a ground keel 8 is installed at the bottom of the longitudinal square tube 2, which improves the overall load-bearing strength of the top and bottom of the longitudinal square tube 2.

[0031] Furthermore, multiple sets of vertical light steel keels 5 are installed between the top keel 3 and the horizontal square tube 6, and multiple sets of horizontal light steel keels 4 are installed between the vertical light steel keels 5, which improves the mechanical strength of the entire wall.
