Description

Technical Field

[0001] The invention relates to the technical field of roofing, and in particular to a water-avoiding node of a roofing steel structure and a building. Background Art

[0002] At present, in order to enhance the stability and waterproofness of the foot of the steel column protruding from the roof, the foot of the steel column is usually covered with concrete. That is to say, at the bottom of the steel column protruding from the roof of the building, a layer of concrete will be poured around the steel column. This can protect the steel column from erosion by the external environment, especially in the roof area with high waterproofing requirements. At the same time, the waterproofing is turned up to the steel column, so that the waterproof layer not only covers the surface of the outer concrete, but also extends upward to wrap a certain height of the lower part of the steel column, thereby forming a continuous waterproof barrier to prevent rainwater from seeping into the building when it flows down the steel column.

[0003] Over time, due to factors such as aging, temperature changes and structural settlement, fine cracks may appear at the joints between the outer concrete and the steel columns. When it rains, rainwater may penetrate through these gaps, especially at the joints between the steel columns and the floor slabs. This is because there are often structural joints or installation gaps here. Once rainwater penetrates, it will cause water leakage inside the floor, affecting the use function and structural safety of the building. Summary of the invention

[0004] In view of this, the present invention provides a water-proof node of a roof steel structure and a building to solve the problem of water leakage inside the floor caused by cracks at the joints between the outer concrete and the steel columns.

[0005] In a first aspect, the present invention provides a water-avoiding node for a roof steel structure, the water-avoiding node comprising:

[0006] The building body is provided with a roof structure, and the roof structure is provided with an interface;

[0007] A support column is inserted into the interface; the support column is provided with an angle steel on the inner side of the roof structure;

[0008] A water-proof plate is sleeved on the support column and is located outside the roof structure to form an overhanging eaves structure; the water-proof plate and the support column are sealed and welded;

[0009] The waterproof component is laid between the bottom of the waterproof plate and the roof structure.

[0010] Beneficial effect: The embodiment of the present invention is provided with a water-proof plate to form an overhanging eaves structure, and the water-proof plate and the support column are sealed and welded. When it rains, since there is no gap between the water-proof plate and the support column, rainwater can flow out along the overhanging eaves structure, thereby preventing rainwater from leaking into the floor along the web of the support column. At the same time, since the waterproof component is also arranged between the bottom of the water-proof plate and the roof structure, even if rainwater can flow along the lower side of the overhanging eaves structure, the waterproof component can prevent rainwater from leaking into the floor along the gap between the support column and the interface. In addition, the appearance of seams facing the sky can be prevented, and the effect of the waterproof component can be effectively guaranteed. Therefore, this embodiment can completely eliminate the problem of water leakage inside the floor.

[0011] In an optional embodiment, along the vertical direction, a side of the water-avoiding plate close to the supporting column is higher than a side of the water-avoiding plate away from the supporting column.

[0012] Beneficial effect: In the embodiment of the present invention, the inner side of the water-proof plate is higher than the outer side. Therefore, after rainwater falls on the water-proof plate, it will automatically flow to the lower outer side, so that it can be discharged outward through the eaves structure and cannot flow back to the lower side of the eaves structure, thereby further improving the overall waterproofness of the water-proof node.

[0013] In an optional embodiment, a slope of 1% to 2% is formed from a side of the water-avoiding plate close to the supporting column to a side of the water-avoiding plate away from the supporting column.

[0014] In an optional embodiment, shear nails are arranged on the sides of the support columns, and concrete is poured on the portion of the support columns that is exposed outside the roof structure.

[0015] Beneficial effect: The embodiment of the present invention arranges shear nails on the side of the support column. After pouring concrete, the shear nails can be simply solidified together with the outer concrete, thereby strengthening the connection and engagement between the outer concrete and the support column, so that the two are stressed together to avoid cracking.

[0016] In an optional implementation, the water avoidance node further includes:

[0017] The anti-cracking steel mesh is arranged on the portion of the support column that is exposed to the roof structure; when pouring concrete on the portion of the support column that is exposed to the roof structure, the anti-cracking steel mesh is also covered.

[0018] In an optional embodiment, the waterproof component is laid on the concrete-wrapped portion of the support column and the outer side of the roof structure.

[0019] In an optional embodiment, the eaves structure is covered with cement mortar.

[0020] In an optional implementation, the water avoidance node further includes:

[0021] The sealing member is arranged at least at the welding line of the waterproof plate and the connection line between the overhanging eaves structure and the waterproof membrane.

[0022] In an optional embodiment, the sealing member is a sealing paste, and the sealing paste is coated on the welding line of the waterproof plate and the connection line between the eaves structure and the waterproof membrane to form a sealing ring.

[0023] In an optional implementation, the water avoidance node further includes:

[0024] A brick wall layer is built along the vertical direction on the concrete-wrapped portion of the support column; the top of the brick wall layer abuts against the overhanging eaves structure.

[0025] In an optional implementation, the water avoidance node further includes:

[0026] The roof outer layer structure is arranged on the outer side of the roof structure; the roof outer layer structure at least includes a roof insulation layer and a roof protection layer.

[0027] In a second aspect, the present invention further provides a building, comprising: a water-avoiding node of a roof steel structure as described in any one of the above-mentioned embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal communication of two components, it can be a wireless connection, or it can be a wired connection. For ordinary workers in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] At present, in order to enhance the stability and waterproofness of the foot of the steel column protruding from the roof, the foot of the steel column is usually covered with concrete. That is to say, at the bottom of the steel column protruding from the roof of the building, a layer of concrete will be poured around the steel column. This can protect the steel column from erosion by the external environment, especially in the roof area with high waterproofing requirements. At the same time, the waterproofing is turned up to the steel column, so that the waterproof layer not only covers the surface of the outer concrete, but also extends upward to wrap a certain height of the lower part of the steel column, thereby forming a continuous waterproof barrier to prevent rainwater from seeping into the building when it flows down the steel column.

[0038] Over time, due to factors such as aging, temperature changes and structural settlement, fine cracks may appear at the joints between the outer concrete and the steel columns. When it rains, rainwater may penetrate through these gaps, especially at the joints between the steel columns and the floor slabs. This is because there are often structural joints or installation gaps here. Once rainwater penetrates, it will cause water leakage inside the floor, affecting the use function and structural safety of the building.

[0039] In view of this, the present invention provides a water-proof node of a roof steel structure and a building to solve the problem of water leakage inside the floor caused by cracks at the joints between the outer concrete and the steel columns.

[0040] Combine the following Figure 1 to Figure 2 , describing an embodiment of the present invention.

[0041] According to an embodiment of the present invention, on the one hand, a water-avoiding node of a roof steel structure is provided, and the water-avoiding node includes a building body, a support column 2, a water-avoiding plate 3 and a waterproof component 4.

[0042] Specifically, in the embodiment of the present invention, the main building is provided with a roof structure 1, and the roof structure 1 is provided with an interface. A support column 2 is inserted into the interface, and the support column 2 is usually a steel column, and an angle steel is arranged on the inner side of the support column 2. In other words, the angle steel is arranged below the floor deck of the roof structure, so that support can be provided for the floor deck. In the actual construction process, bolts can also be arranged in the connection area between the angle steel and the concrete 6 to connect the outer concrete 6, so as to further enhance the stability of the overall structure.

[0043] Furthermore, the water-repellent plate 3 is sleeved on the support column 2 and is located outside the roof structure 1 to form an overhanging eaves structure. That is, the water-repellent plate 3 is an annular plate, and the through hole in the center of the annular plate can be sleeved on the support column 2. In order to prevent rainwater from flowing through the gap between the water-repellent plate 3 and the support column 2, the water-repellent plate 3 and the support column 2 can be sealed and welded. And when welding, line welding can be used. If spot welding is used, water leakage will still occur.

[0044] As for the overall structure type of the water-repellent plate 3, it can be an integrally formed structure, or a plurality of small fan-shaped structures which are then welded together during installation.

[0045] Furthermore, the waterproof component 4 is laid between the bottom of the waterproof plate 3 and the roof structure 1. The waterproof component 4 can be a waterproof additional layer and a waterproof layer. As for the specific waterproof material, this embodiment does not limit it, and those skilled in the art can change it according to the actual situation, as long as the same technical effect can be achieved.

[0046] In this way, the embodiment of the present invention is provided with a water-proof plate 3 to form an overhanging eaves structure, and the water-proof plate 3 and the support column 2 are sealed and welded. When it rains, since there is no gap between the water-proof plate 3 and the support column 2, rainwater can flow out along the overhanging eaves structure, thereby preventing rainwater from leaking into the floor along the web of the support column 2. At the same time, since the waterproof component 4 is also arranged between the bottom of the water-proof plate 3 and the roof structure 1, even if rainwater can flow along the lower side of the overhanging eaves structure, the waterproof component 4 can also prevent rainwater from leaking into the floor along the gap between the support column 2 and the interface. In addition, the appearance of seams facing the sky can be prevented, and the effect of the waterproof component 4 can be effectively guaranteed. Therefore, this embodiment can completely prevent the problem of water leakage inside the floor.

[0047] Further, in an optional embodiment, along the vertical direction, a side of the water-avoiding plate 3 close to the supporting column 2 is higher than a side of the water-avoiding plate 3 away from the supporting column 2 .

[0048] With such a configuration, the embodiment of the present invention makes the inner side of the water-proof plate 3 higher than the outer side. Then, after rainwater falls on the water-proof plate 3, it will automatically flow to the lower outer side, so that it can be discharged outward through the eaves structure and cannot flow back to the lower side of the eaves structure, thereby further improving the overall waterproofness of the water-proof node.

[0049] Furthermore, in an optional embodiment, a slope of 1% to 2% is formed from a side of the water-avoiding plate 3 close to the supporting column 2 to a side of the water-avoiding plate 3 away from the supporting column 2 .

[0050] Furthermore, in an optional embodiment, shear studs 5 are arranged on the side of the support column 2, and concrete 6 is poured on the portion of the support column 2 that is exposed outside the roof structure 1.

[0051] In this way, the embodiment of the present invention arranges shear nails 5 on the side of the support column 2. After pouring the concrete 6, the shear nails 5 can be simply solidified together with the outer concrete 6, thereby strengthening the connection and engagement between the outer concrete 6 and the support column 2, so that the two are subjected to stress together to avoid cracking.

[0052] Furthermore, in an optional embodiment, the water avoidance node further includes an anti-cracking steel mesh 7, which is arranged on the portion of the support column 2 that is exposed to the roof structure 1. When pouring concrete 6 on the portion of the support column 2 that is exposed to the roof structure 1, the anti-cracking steel mesh 7 is also covered.

[0053] Furthermore, in an optional embodiment, the waterproof component 4 is laid on the outer part of the concrete 6 of the support column 2 and the outer side of the roof structure 1. Then, cement nails are used to further fix the waterproof component 4 on the outer concrete 6. It should be noted that since the support column 2 is arranged in a vertical direction and the outer side of the roof structure 1 is usually in a horizontal direction, the support column 2 and the roof structure 1 are usually at a right angle. The waterproof component 4 is not easy to bend excessively. Therefore, in order to facilitate the waterproof component 4 to fit with each part without excessive bending, cement mortar 8 can be used to make a fillet at the right angle to facilitate the fitting with the waterproof component 4 after bending.

[0054] Furthermore, in an optional embodiment, the eaves structure is covered with cement mortar 8. Specifically, a 20 mm thick cement mortar 8 covering layer can be added to the outer surface of the eaves, and the cement mortar 8 can be M20 polymer cement mortar 8. The 28-day cubic compressive strength under standard conditions is not less than 20 MPa. The polymer cement mortar 8 is modified by adding polymer emulsion to ordinary cement mortar 8, and has better adhesion, durability and crack resistance.

[0055] Furthermore, in an optional embodiment, the water-avoiding node further includes a seal, and the seal is at least arranged at the welding line of the water-avoiding plate 3 and the connection line between the overhanging eaves structure and the waterproof membrane.

[0056] The specific type of the sealing member may be a sealing sheet or a sealing ring made of rubber or silicone. Of course, this embodiment is only an example, but is not limited thereto, and those skilled in the art may make changes according to actual conditions as long as the same technical effect can be achieved.

[0057] Furthermore, in an optional embodiment, the sealing member is a sealing paste 9, and the sealing paste 9 is coated on the welding line of the waterproof plate 3 and the connection line between the eaves structure and the waterproof membrane to form a sealing ring.

[0058] Furthermore, in an optional embodiment, the water-avoiding node further includes a brick wall layer 10, which is built in the vertical direction on the portion of the support column 2 that is covered by the concrete 6; the top of the brick wall layer 10 is in contact with the eaves structure.

[0059] Furthermore, in an optional embodiment, the water-avoiding node also includes a roof outer layer structure, which is arranged on the outer side of the roof structure 1, and the roof outer layer structure includes at least a roof insulation layer and a roof protective layer, and the roof protective layer can adopt a rigid structure.

[0060] In a second aspect, the present invention further provides a building, comprising: a water-avoiding node of a roof steel structure as described in any one of the above-mentioned embodiments.

[0061] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
