Description

Technical Field

[0001] The utility model relates to the technical field of steel node reinforcement, in particular to a steel column connection node capable of pouring concrete. Background Art

[0002] At present, steel structure buildings are more and more widely used, and we have seen a large number of innovative and unique architectural designs begin to adopt steel structures; the structural system and force transmission path of these buildings have put forward higher requirements on the design of steel column nodes; especially in large buildings, there are high requirements for the aesthetics and strength of the node appearance; however, traditional steel column nodes can no longer meet current needs, and their limitations are obvious; the traditional steel column node design is structurally complex, and the welding and assembly process of the steel column nodes by adding support plates is cumbersome, and it is not easy to quickly assemble and weld with the steel structure, which makes it difficult to speed up the construction progress while ensuring the overall stability of the steel structure.

[0003] Conventional steel column nodes adopt the form of spherical steel cap + internal stiffening plate. Since the interior of the spherical steel cap is arc-shaped, the production and installation of the stiffening plate is relatively complicated. In order to ensure that the stiffening plate is tightly connected to the spherical steel cap, the stiffening plate needs to be made into an arc-shaped stiffening plate that fits the spherical steel cap, which also puts forward strict requirements on the processing accuracy. Since both the stiffening plate and the spherical steel cap are arc-shaped and the internal space is limited, manual welding is also very difficult, and the quality of the steel column node is difficult to guarantee. Moreover, the production and installation need to be completed manually. When the nodes are made manually, the quality of conventional steel column nodes is often difficult to guarantee due to the different qualities of the construction personnel. Since the stiffening plate is used as the support, when the upper load of the steel column node is too large, the stiffening plate in the node will produce buckling deformation due to excessive force, so the bearing capacity of the conventional steel column node will be greatly reduced. At the same time, due to its own complexity, the conventional steel column node also has a certain impact on on-site construction, which is not conducive to rapid construction and affects construction efficiency.

[0004] The utility model aims to provide a steel column connection node that can be poured with concrete, so as to solve the problems of complex structure, inconvenient installation, high requirements on personnel quality, unreasonable structure and high cost in the prior art.

[0005] The embodiment of the utility model is achieved as follows:

[0006] The embodiment of the utility model provides a steel column connection node that can be poured with concrete, which includes a lower steel column and an upper steel column;

[0007] A steel structure column connection node is provided between the lower steel column and the upper steel column, and the same end of the lower steel column and the upper steel column are fixedly connected to the steel structure column connection node;

[0008] The steel structure column connection node has a volume cavity inside, and a perfusion hole is opened on the outer wall of the steel structure column connection node, and the perfusion hole and the volume cavity are interconnected;

[0009] The interior of the volume cavity is provided with high-strength concrete.

[0010] When in use, firstly, it is cast on site, the bottom of the above-mentioned steel structure column connection node is welded to the top of the above-mentioned lower steel column, and then the above-mentioned upper steel column is welded to the top of the above-mentioned steel structure column connection node, and the above-mentioned high-strength concrete is injected into the above-mentioned volume cavity inside the above-mentioned steel structure column connection node through the above-mentioned pouring hole; secondly, the factory building is prefabricated, when in the factory building, the above-mentioned high-strength concrete is injected into the above-mentioned volume cavity, and then transported to the site and welded to the above-mentioned lower steel column and the above-mentioned upper steel column.

[0011] The present embodiment discloses a concrete-castable steel column connection node, which has the casting hole at the top of the steel column connection node, so that the high-strength concrete can be cast inside the steel column connection node to increase the pressure resistance of the steel column connection node, thereby making the concrete-castable steel column connection node simple in structure, easy to install, with low requirements on the quality of personnel, reasonable in structure, and fully utilizing the compressive properties of concrete materials and the beneficial effects of low cost.

[0012] Optionally, the high-strength concrete is tightly attached to the inner wall of the volume cavity.

[0013] With such arrangement, the support module supports the interior of the steel structure column connection node, thereby increasing the overall pressure-bearing capacity of the steel structure column connection node.

[0014] Optionally, the above-mentioned pouring hole is located at the top of the connection node of the above-mentioned steel structure column.

[0015] With such arrangement, the positions of the above-mentioned pouring holes are convenient for pouring the above-mentioned high-strength concrete, and can make the above-mentioned volume cavity be poured full, avoiding the appearance of cavities, thereby ensuring the pressure-bearing capacity of the above-mentioned steel structure column connection nodes.

[0016] Optionally: the steel structure column connection node has a spherical steel cap, the lower part of the spherical steel cap is provided with an end plate, and the bottom end of the spherical steel cap is vertically fixedly connected to the end plate.

[0017] With such arrangement, the outer wall of the spherical steel cap can connect more of the upper steel columns, and the arrangement of the end plate limits the position of the support module, so that the support module is located inside the connection node of the steel structure column, which is conducive to the pouring of high-strength concrete.

[0018] Optionally: the side of the end plate away from the spherical steel cap is vertically fixedly connected to the lower steel column.

[0019] Such arrangement enables the steel structure column connection node to be connected to the lower steel column as a whole, effectively improving the overall strength of the steel structure and facilitating the transmission of pressure.

[0020] Optionally: a plurality of reinforcement members are provided at the angle between the connection nodes of the upper steel column and the steel structure column.

[0021] With such arrangement, the plurality of reinforcement members can provide effective support for the upper steel columns, thereby improving the overall strength and stability of the entire steel structure.

[0022] Optionally: a plurality of the reinforcement members are evenly distributed along the circumference of the connection node of the steel structure column and welded at the angle between the upper steel column and the connection node of the steel structure column.

[0023] With such arrangement, the uniform distribution of the plurality of reinforcement members can evenly disperse the pressure transmitted from the upper portion, so that the connection nodes of the steel structure columns are evenly stressed, effectively avoiding damage to the connection nodes of the steel structure columns due to concentrated pressure.

[0024] Optionally, a detachable sealing plug is provided inside the above-mentioned perfusion hole, and the outer wall of the sealing plug is tightly matched with the hole wall of the above-mentioned perfusion hole.

[0025] With such arrangement, the sealing plug can seal the above-mentioned pouring hole, effectively preventing the above-mentioned high-strength concrete inside the above-mentioned steel structure column connection node from being eroded and weathered by rainwater, thereby ensuring the quality of the above-mentioned high-strength concrete and extending the compressive service life of the steel column connection node.

[0026] Optionally: a plurality of hooks are provided on the inner wall of the steel structure column connection node, one end of the plurality of hooks has a bent hook, and the other ends of the plurality of hooks are vertically fixedly connected to the inner wall of the steel structure column connection node.

[0027] With such an arrangement, when the steel structure column connection node needs to be prefabricated and poured with the high-strength concrete in the factory, if the hook is not present, the high-strength concrete inside the poured steel structure column connection node is prone to shaking, which poses a great safety risk and affects the pressure bearing capacity. The arrangement of the hook effectively enhances the connection strength between the steel structure column connection node and the high-strength concrete, so that the device can be used to pour the high-strength concrete on site or to pour the high-strength concrete during prefabrication in the factory, and the high-strength concrete is more tightly connected to the steel structure column connection node.

[0028] Optionally: the spherical steel cap, the end plate and the lower steel column are all located on the same axis.

[0029] Such an arrangement enables the lower steel column to well bear the pressure transmitted from the spherical steel cap and the end plate, which is beneficial to dispersing the pressure into the ground and achieving a good supporting effect.

[0030] Based on the above description, the utility model discloses a steel column connection node that can be poured with concrete, which has the advantages of simple structure, convenient installation, low requirements on personnel quality, reasonable structure, and full use of the compressive properties of concrete materials and low cost.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example

[0039] See also Figure 1 , Figure 2 and Figure 3 , this embodiment provides a steel column connection node that can be poured with concrete, including a lower steel column 1 and an upper steel column 2;

[0040] A steel structure column connection node 3 is provided between the lower steel column 1 and the upper steel column 2, and the same end of the lower steel column 1 and the upper steel column 2 are fixedly connected to the steel structure column connection node 3;

[0041] The steel structure column connection node 3 has a volume cavity 4 inside, and a perfusion hole 5 is opened on the outer wall of the steel structure column connection node 3, and the perfusion hole 5 and the volume cavity 4 are interconnected;

[0042] The interior of the volume chamber 4 comprises high-strength concrete 6 .

[0043] When in use, firstly, it is cast on site, the bottom of the steel structure column connection node 3 is welded to the top of the lower steel column 1, and then the upper steel column 2 is welded to the top of the steel structure column connection node 3, and the high-strength concrete 6 is injected into the volume cavity 4 inside the steel structure column connection node 3 through the pouring hole 5; secondly, the factory building is prefabricated, and when it is in the factory building, the high-strength concrete 6 is injected into the volume cavity 4, and then transported to the site to be welded with the lower steel column 1 and the upper steel column 2.

[0044] The present embodiment discloses a concrete-castable steel column connection node, which has a casting hole 5 at the top of the steel column connection node 3, so that high-strength concrete 6 can be poured inside the steel column connection node 3 to increase the pressure resistance of the steel column connection node 3, thereby making the concrete-castable steel column connection node have a simple structure, easy installation, low requirements on personnel quality, reasonable structure, and fully utilizing the compressive properties of concrete materials and the beneficial effects of low cost.

[0045] In this embodiment, the size of the pouring hole 5 is 150 mm, and the specific size can be adjusted according to the actual situation of the steel column node. An admixture that prevents concrete shrinkage needs to be added to the high-strength concrete 6 to avoid insufficient internal filling of the steel structure column connection node 3.

[0046] See also Figure 1 , Figure 2 and Figure 3The high-strength concrete 6 is tightly attached to the inner wall of the volume cavity 4, and supports the interior of the steel structure column connection node 3 through the support module, thereby increasing the overall pressure of the steel structure column connection node 3.

[0047] The pouring hole 5 is located at the top of the steel structure column connection node 3. The location of the pouring hole 5 is convenient for pouring high-strength concrete 6, which can fill the volume cavity 4 and avoid the appearance of a cavity, thereby ensuring the pressure-bearing capacity of the steel structure column connection node 3.

[0048] The steel structure column connection node 3 has a spherical steel cap 7, and an end plate 8 is provided at the bottom of the spherical steel cap 7. The bottom end of the spherical steel cap 7 is vertically fixedly connected to the end plate 8. The outer wall of the spherical steel cap 7 can connect more upper steel columns 2. The setting of the end plate 8 limits the position of the support module, so that the support module is located inside the steel structure column connection node 3, which is conducive to the pouring of high-strength concrete.

[0049] See also Figure 1 , Figure 2 and Figure 3 The end plate 8 is vertically fixedly connected to the lower steel column 1 on one side away from the spherical steel cap 7, so that the steel structure column connection node 3 can be connected to the lower steel column 1 as a whole, which effectively improves the overall strength of the steel structure and facilitates the transmission of pressure.

[0050] A plurality of reinforcement members 9 are provided at the angle between the upper steel column 2 and the connection node 3 of the steel structure column. The plurality of reinforcement members 9 can provide effective support for the upper steel column 2, thereby improving the overall strength and stability of the entire steel structure.

[0051] A number of reinforcement members 9 are evenly distributed along the circumference of the steel structure column connection node 3 and welded at the angle between the upper steel column 2 and the steel structure column connection node 3. The even distribution of a number of reinforcement members 9 can evenly disperse the pressure transmitted from the upper part, so that the steel structure column connection node 3 is evenly stressed, effectively avoiding damage to the steel structure column connection node 3 due to concentrated pressure.

[0052] See also Figure 1 , Figure 2 and Figure 3 A detachable sealing plug (not shown in the figure) is provided inside the pouring hole 5. The outer wall of the sealing plug is tightly matched with the hole wall of the pouring hole 5. The sealing plug can seal the pouring hole 5, effectively preventing the high-strength concrete 6 inside the steel structure column connection node 3 from being eroded and weathered by rainwater, thereby ensuring the quality of the high-strength concrete 6 and extending the compressive service life of the steel column connection node.

[0053] There are several hooks 10 on the inner wall of the steel structure column connection node 3, one end of the hooks 10 has a bent hook 11, and the other ends of the hooks 10 are vertically fixedly connected to the inner wall of the steel structure column connection node 3. When the steel structure column connection node 3 needs to be prefabricated and poured with high-strength concrete 6 in the factory, if there is no hook 10, the high-strength concrete 6 inside the poured steel structure column connection node 3 is easy to shake, the safety risk is high, and the pressure bearing capacity will be affected. The setting of the hook 10 effectively enhances the connection strength between the steel structure column connection node 3 and the high-strength concrete 6, so that the device can not only pour the high-strength concrete 6 on site, but also pour the high-strength concrete 6 when prefabricated in the factory, and the high-strength concrete 6 is more tightly connected to the steel structure column connection node 3.

[0054] The spherical steel cap 7, the end plate 8 and the lower steel column 1 are all located on the same axis. This arrangement enables the lower steel column 1 to well bear the pressure transmitted from the spherical steel cap 7 and the end plate 8, which is beneficial to disperse the pressure into the ground and provide a good supporting effect.

[0055] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, a spherical steel cap 7 and an end plate 8 structure are adopted. There is no need to process the internal arc stiffening plate, and there is no need to weld the stiffening plate to the spherical steel cap 7. Therefore, the processing and production are simple. It is only necessary to reserve a pouring hole 5 on the top of the spherical steel cap 7, which can be reserved in the factory or cut on site.

[0056] In this embodiment, in order to facilitate installation, the spherical steel cap 7 and the end plate 8 can also be welded in the factory or on-site. Since it only needs to be welded to the end plate 8 on the outside of the spherical steel cap 7, the operating space is large, the construction is simple and convenient, and the quality of the steel structure column connection node 3 is easy to ensure; due to the large operating space and simple structure, the quality after splicing and installation by workers is also easier to ensure.

[0057] In this embodiment, when pouring the high-strength concrete 6, the grade of the concrete can be determined according to the bearing capacity requirement.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
