Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a safety connector for steel structure nodes. Background Technology

[0002] Steel structures possess high stability and load-bearing capacity, making them widely used in building construction. In some large-span structures, steel structural components need to be spliced. For example, when constructing large-span beams, H-beams are used for splicing, with adjacent H-beams connected and fixed by high-strength bolts, welding, or other methods.

[0003] The connection node between two steel structural members is the most vulnerable part of the entire steel structure to external environmental damage, such as impacts and rain corrosion. Therefore, the connection node becomes a weak point in the steel structure. Traditional high-strength bolt and welded connections have poor reliability and durability, affecting the overall structural integrity and stability of the steel structure. Furthermore, the connection node between two steel structural members is easily affected by wind and other factors after being hoisted to a height, making butt welding difficult and posing significant safety hazards during welding construction. Therefore, there is a need to provide a safe connection component for steel structural nodes that can solve the problems of poor reliability and durability of existing steel structural connection nodes, as well as the difficulties and safety hazards associated with welding at high locations. Summary of the Invention

[0004] The purpose of this utility model is to provide a safe connector for steel structure nodes, which can solve the problems of poor connection reliability and durability of steel structure connection nodes in the prior art, as well as the difficulty of welding at high points of connection nodes and the existence of safety hazards.

[0005] This utility model is implemented as follows:

[0006] A safety connector for steel structure nodes includes a protective connector and a connecting plate. The protective connector has a T-shaped through-slot that matches the H-beam node connector, allowing the protective connector to slidably fit onto the flange and web of the H-beam node connector via the through-slot, thus connecting the protective connector to the connection node of two adjacent H-beam node connectors. A second connecting hole is formed at the end of the flange of the H-beam node connector, and a third connecting hole is provided at one end of the protective connector, allowing the protective connector to be connected and fixed to the flange of the H-beam node connector through the second and third connecting holes. A fourth connecting hole is formed on the connecting plate, and a first connecting hole is formed on the web of the H-beam node connector, allowing the connecting plate to be fixedly connected to two adjacent H-beam node connectors through the first and fourth connecting holes.

[0007] The bottom opening of the through groove of the protective connector is formed with a connecting baffle, which is attached to the plate surface of the connecting plate away from the web of the H-beam steel node connector.

[0008] The length of the connecting baffle is the same as the length of the protective connector. The ends of the protective connector and the connecting baffle are provided with baffles. The surface of the baffle is perpendicular to the length direction of the connecting baffle, and the inner end of the baffle is flush with the edge of the vertical section of the through groove, so that the baffle can abut against the end of the connecting plate and the web of the H-beam steel node connector.

[0009] The connecting baffle and the protective connector are an integral structure.

[0010] A sliding groove is formed in the horizontal section of the through groove, and the sliding groove is set at equal lengths along the length direction of the through groove; a slide rail is formed on the wing plate of the H-shaped steel node connector, and the slide rail is set at equal lengths along the length direction of the H-shaped steel node connector; the slide rail is slidably fitted into the sliding groove.

[0011] One of the protective connectors is sleeved on the top of the upper flange and the top of the web of the H-beam steel node connector, and the connecting baffle of the protective connector is attached to the top surface of the connecting plate; two of the protective connectors are respectively sleeved on the top and bottom of the upper and lower flanges and the top and bottom of the web of the H-beam steel node connector, and the two protective connectors are symmetrically arranged, and the connecting baffles of the two protective connectors are respectively attached to the top and bottom surfaces of the connecting plate.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model, by providing a connecting plate and a protective connector, connects the web plates of two adjacent H-beam steel node connectors, and the protective connector is sleeved on the ends of the wing plates and web plates of two adjacent H-beam steel node connectors. This increases the stress points at the connection nodes of two adjacent H-beam steel node connectors. The way the protective connector wraps around the connection node greatly increases the stress stability and safety of the connection nodes of two adjacent H-beam steel node connectors, ensuring that the connection nodes will not fall off or shake during welding construction and will be more stable during long-term use, effectively improving the reliability, durability and safety of the connection nodes of two adjacent H-beam steel node connectors.

[0014] 2. Because this utility model is equipped with a connecting baffle and a baffle plate, and the connecting baffle plate is set to fit against the surface of the connecting plate, the connecting plate can slide to the side of the connecting node of two adjacent H-beam steel node connectors. This allows welding operations to be performed on the connecting node while the connecting parts are in place, improving construction safety and preventing the connecting plate from falling off. At the same time, after the baffle plate is set perpendicular to the surface of the connecting plate, the connecting plate is bidirectionally limited by the connecting baffle and the baffle plate, thereby improving the stability and reliability of the connecting plate and thus improving the reliability and durability of the connecting node of two adjacent H-beam steel node connectors.

[0015] 3. Because this utility model is equipped with a sliding groove and a sliding rail, it can increase the stress area between the protective connector and the H-beam steel node connector, improve the reliability and durability of the connection node between two adjacent H-beam steel node connectors, and at the same time, the relative sliding of the sliding groove and the sliding rail facilitates the sleeve positioning and stable movement of the protective connector, making the installation process more convenient.

[0016] 4. This utility model has a simple structure, is easy to source materials and manufacture, is convenient to construct, and is safe during the welding process. It can be widely applied to the construction of steel structure nodes. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Please see the appendix Figure 1 To be continued Figure 5A safety connector for steel structure nodes includes a protective connector 1 and a connecting plate 3. The protective connector 1 has a T-shaped through groove 12 that matches an H-beam steel node connector 2, allowing the protective connector 1 to slidably fit onto the flange and web of the H-beam steel node connector 2 via the through groove 12, thus connecting the protective connector 1 to the connection node of two adjacent H-beam steel node connectors 2. A second connecting hole 8 is formed at the end of the flange of the H-beam steel node connector 2, and a third connecting hole 9 is provided at one end of the protective connector 1 via an ear plate, allowing the protective connector 1 to be connected and fixed to the flange of the H-beam steel node connector 2 via high-strength bolts through the second connecting hole 8 and the third connecting hole 9. A fourth connecting hole 11 is formed on the connecting plate 3, and a first connecting hole 4 is formed on the web of the H-beam steel node connector 2, allowing the connecting plate 3 to be fixedly connected to two adjacent H-beam steel node connectors 2 via high-strength bolts through the first connecting hole 4 and the fourth connecting hole 11.

[0025] At the connection node of two adjacent H-beam joint connectors 2, the two H-beam joint connectors 2 are connected by a connecting plate 3 via high-strength bolts, first connecting holes 4, and fourth connecting holes 11. Preferably, each H-beam joint connector 2 has two rows of first connecting holes 4 at its web end, and the connecting plate 3 has four rows of fourth connecting holes 11. The number and diameter of the holes in each row can be adjusted according to actual connection requirements to ensure the reliability of the connection between adjacent H-beam joint connectors 2.

[0026] Preferably, two connecting plates 3 can be symmetrically arranged at the connection point of two adjacent H-beam node connectors 2, that is, the two connecting plates 3 are respectively attached to the two surfaces of the web of the H-beam node connector 2, thereby improving the reliability of the connection between the two adjacent H-beam node connectors 2.

[0027] The protective connector 1 is used to fit onto the flange and part of the web of the H-beam joint connector 2. It not only facilitates safe construction work on the connection nodes of two adjacent H-beam joint connectors 2 and prevents relative movement during welding, but also protects the connection nodes of the two adjacent H-beam joint connectors 2 by wrapping and protecting them. This greatly distributes the stress on the connection nodes and effectively reduces the adverse effects of external impacts and rainwater corrosion on the connection nodes, thereby further improving the reliability and durability of the connection nodes of the two adjacent H-beam joint connectors 2.

[0028] Preferably, two ear plates can be provided at one or both ends of the protective connector 1, and a third connecting hole 9 can be opened on each ear plate. Two second connecting holes 8 are correspondingly provided on the wing plate at the connecting end of the H-beam steel node connector 2. Thus, the protective connector 1 can be fixed to the H-beam steel node connector 2 through the second connecting hole 8 and the third connecting hole 9 by high-strength bolts, ensuring that the protective connector 1 is sleeved at the connecting node of two adjacent H-beam steel node connectors 2, and preventing the connecting node of two adjacent H-beam steel node connectors 2 from breaking under stress.

[0029] Please see the appendix Figure 4 and attached Figure 5 The bottom opening end of the through groove 12 of the protective connector 1 is formed with a connecting baffle 7, which is attached to the plate surface of the connecting plate 3 away from the web of the H-beam steel node connector 2.

[0030] The connecting baffle 7 is attached to the outer wall of the connecting plate 3 to limit the connecting plate 3, ensuring that the connecting plate 3 is reliably installed and does not fall off. This helps to improve the reliability of the connection node of the two adjacent H-beam node connectors 2, and also ensures that the connecting plate 3 will not fall off during the welding process of the connection node.

[0031] Please see the appendix Figure 5 The length of the connecting baffle 7 is the same as the length of the protective connector 1. The ends of the protective connector 1 and the connecting baffle 7 are provided with baffles 10. The surface of the baffle 10 is perpendicular to the length direction of the connecting baffle 7, and the inner end of the baffle 10 (with the end closer to the through groove 12 as the inner end and the end farther from the through groove 12 as the outer end) is flush with the edge of the vertical section of the through groove 12, so that the baffle 10 can abut against the end of the connecting plate 3 and the web of the H-shaped steel node connector 2.

[0032] After the protective connector 1 and the connecting plate 3 are installed and fixed, the baffle 10 can be installed at the ends of the protective connector 1 and the connecting baffle 7 by bolts. The plate surface of the baffle 10 is perpendicular to the length direction of the connecting baffle 7, so that the inner end of the baffle 10 can abut against the web of the H-beam steel node connector 2, and one side of the baffle 10 can fit against the end of the connecting baffle 7 and the end of the connecting plate 3, thereby further limiting the connection plate 3.

[0033] Preferably, the lengths of the connecting plate 3, the protective connecting member 1, and the connecting baffle 7 are the same. Baffles 10 can be provided at both ends of the connecting baffle 7 to ensure the relative stability of the connecting plate 3 and the protective connecting member 1 and to prevent slippage, thereby further ensuring the reliability and durability of the connection node of the two adjacent H-beam node connectors 2.

[0034] The connecting baffle 7 and the protective connector 1 are an integral structure.

[0035] Preferably, the number of connecting baffles 7 is the same as the number of connecting plates 3, and usually two connecting baffles 7 are symmetrically arranged. The connecting baffles 7 and the protective connecting parts 1 are integrally formed using steel materials of the same specifications as the H-beam steel node connecting parts 2, which has high structural strength, is not easily deformed or damaged, and has good durability.

[0036] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5 A sliding groove 6 is formed in the horizontal section of the through groove 12, and the sliding groove 6 is set at the same length along the length direction of the through groove 12; a slide rail 5 is formed on the wing plate of the H-shaped steel node connector 2, and the slide rail 5 is set at the same length along the length direction of the H-shaped steel node connector 2; the slide rail 5 is slidably fitted into the sliding groove 6.

[0037] Preferably, the cross sections of the slide groove 6 and the slide rail 5 are matching triangles, so that the slide rail 5 can be slidably fitted into the slide groove 6, ensuring that the protective connector 1 is stably sleeved and slidable on the H-beam steel node connector 2, without misalignment or displacement, thereby ensuring that the connection nodes of two adjacent H-beam steel node connectors 2 are reliably connected through the sleeve of the protective connector 1.

[0038] One of the protective connectors 1 is sleeved on the top of the upper flange and the top of the web of the H-beam node connector 2, and the connecting baffle 7 of the protective connector 1 is attached to the top surface of the connecting plate 3; two of the protective connectors 1 are respectively sleeved on the top and bottom of the upper and lower flanges and the top and bottom of the web of the H-beam node connector 2, and the two protective connectors 1 are symmetrically arranged, and the connecting baffles 7 of the two protective connectors 1 are respectively attached to the top and bottom surfaces of the connecting plate 3.

[0039] If the dimensions of H-beam steel node connector 2 are less than 250*125*6*9 mm and the unit weight is less than 21.7 g / L, one protective connector 1 can be used for connection. If the dimensions of H-beam steel node connector 2 are greater than 250*125*6*9 mm and the unit weight is greater than 21.7 g / L, two protective connectors 1 can be used for connection. The number of protective connectors 1 can be adjusted adaptively during actual construction based on the load and stress conditions of the connection node of H-beam steel node connector 2.

[0040] Please see the appendix Figure 1 To be continued Figure 5 The construction method and working principle of this utility model are as follows:

[0041] Based on the specifications, load, and stress conditions of the H-beam steel node connector 2 in the steel structure, select the appropriate protective connector 1 and connecting plate 3. The surfaces of protective connector 1, H-beam steel node connector 2, and connecting plate 3 are all coated with anti-corrosion and fire-retardant paint. The following explanation uses two protective connectors 1 and two connecting plates 3 as an example:

[0042] Step 1: Connect one protective connector 1 to the top connection node of two adjacent H-beam steel node connectors 2 through the slide groove 6 and slide rail 5, and connect the other protective connector 1 to the bottom connection node of two adjacent H-beam steel node connectors 2.

[0043] Step 2: Place the two connecting plates 3 at the bottom connecting nodes of the two adjacent H-beam steel node connectors 2. The two connecting plates 3 are respectively attached to the two web surfaces of the two H-beam steel node connectors 2, and the connecting baffles 7 of the two protective connectors 1 are attached to the top and bottom edges of the two connecting plates 3.

[0044] Step 3: When welding two adjacent H-beam node connectors 2, the connecting plate 3 slides between the H-beam node connector 2 and the connecting baffle 7. Moving the connecting plate 3 until the connecting node of the two adjacent H-beam node connectors 2 is exposed allows for web welding at the connecting node. At this time, the connecting plate 3 is limited by the connecting baffle 7 and will not detach from the H-beam node connector 2. When welding the top wing plate, remove the top protective connector 1 onto one of the H-beam node connectors 2. The two H-beam node connectors 2 are connected stably and safely through the bottom protective connector 1, the two connecting plates 3, and the welding node at the web. When welding the bottom wing plate, remove the bottom protective connector 1 onto one of the H-beam node connectors 2. The two H-beam node connectors 2 are connected stably and safely through the top protective connector 1, the two connecting plates 3, and the welding nodes at the web and top wing plate.

[0045] Step 4: Connect and fix the protective connector 1 to the H-beam steel node connector 2 using high-strength bolts through the second connecting hole 8 and the third connecting hole 9.

[0046] Step 5: Slide the connecting plate 3 to the node position, and rivet the connecting plate 3 to the two adjacent H-beam steel node connectors 2 through the first connecting hole 4 and the fourth connecting hole 11 with high-strength bolts.

[0047] Step 6: Install baffle 10 at the ends of the connecting baffle 7 of the two protective connectors 1 with screws, so that the inner end of baffle 10 abuts against the web of the H-beam steel node connector 2, and the plate surface of baffle 10 abuts against the ends of the connecting baffle 7 and the connecting plate 3, to prevent the connecting plate 3 from loosening or slipping under force.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
