Description

Technical Field

[0001] This utility model relates to the field of metal roofing construction technology, and more specifically, to a metal roofing column penetration system. Background Technology

[0002] In the construction industry, metal roofing is widely used due to its advantages such as light weight, high strength, and convenient construction. However, the column penetration areas of metal roofs have long faced severe waterproofing challenges. As the key connection point between the metal roof and the building's structural columns, the column penetration area has a complex structure involving the junction and transition of multiple materials, making traditional waterproofing methods ineffective. Existing single-layer waterproofing structures have significant defects in column penetration areas. On the one hand, due to the different thermal expansion coefficients of the metal roof and the column, relative displacement occurs under external forces such as temperature changes, wind loads, and snow loads, leading to cracks in the single-layer waterproofing layer. Rainwater can easily seep into the interior through these cracks, causing roof leaks. On the other hand, the construction precision of the column penetration end face is difficult to guarantee, resulting in poor surface flatness. The single-layer waterproofing layer cannot adhere tightly to the end face to form an effective waterproof seal, further increasing the risk of leakage. Furthermore, traditional waterproofing materials have poor durability in column penetration areas; long-term exposure to harsh environments easily leads to aging, cracking, and loss of waterproofing function. If the roof leaks, it will not only affect the normal use of the building, but also damage the interior decoration and equipment, increasing maintenance costs. Utility Model Content

[0003] In view of the above-mentioned technical problems in related technologies, this utility model provides a metal roof column penetration system that can solve the above problems.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0005] A metal roof column system includes a keel frame, a corrosion-resistant roof panel on top of the keel frame, and a truss support column fixedly installed at the top of the keel frame. The truss support column penetrates the corrosion-resistant roof panel, and a soft waterproof layer is provided at the penetration point between the truss support column and the corrosion-resistant roof panel. The corrosion-resistant roof panel is integrally formed with ribs, and galvanized steel folding members are fixedly installed on the ribs by screws A. A main truss lower chord is welded to the top of the truss support column, and double-layer steel folding members are welded and fixed to both ends of the main truss lower chord. The double-layer steel folding members are connected to the top of the flashing by screws B, and the bottom end of the flashing is fixedly connected to the galvanized steel folding members by rivets.

[0006] Furthermore, the double-layer steel folding member includes an outer folding member and an inner folding member. The flashing plate is inserted between the outer folding member and the inner folding member, and the top of the outer folding member is welded and fixed to the outer surface of the lower chord of the main truss.

[0007] Furthermore, the flashing is located on the outer side above the supporting column, and the bottom end of the flashing is integrally formed with a water-retaining fold. The top of the galvanized steel fold is fixed to the inner side of the water-retaining fold.

[0008] Furthermore, the corrosion-resistant roof panel has an opening to accommodate the penetration of the support column, and a soft waterproof layer is set above the contact surface between the opening and the support column. The soft waterproof layer includes waterproof coating A, waterproof cloth A, waterproof coating B, waterproof cloth B and waterproof coating applied sequentially from bottom to top.

[0009] Furthermore, the welding point between the outer layer and the lower chord of the main truss is located at one-third of the diameter height of the circumference of the lower chord of the main truss.

[0010] The beneficial effects of this utility model are as follows: The device of this application adopts a double-layer steel folding structure to block and seal the outside of the column penetration area for waterproofing, and combines the double-layer waterproofing method of implementing a soft waterproof layer on the end face of the metal roof through the column to reduce the risk of water leakage in the roof through the column.

[0019] like Figure 1-3 As shown, this utility model discloses a metal roof column system, including a keel frame, a corrosion-resistant roof panel 7 laid on the top of the keel frame, a supporting column 1 fixedly installed at the top of the keel frame, the supporting column 1 penetrating the corrosion-resistant roof panel 7, a soft waterproof layer 2 provided at the penetration point between the supporting column 1 and the corrosion-resistant roof panel 7, the corrosion-resistant roof panel 7 integrally formed with ribs, galvanized steel folding pieces 5 fixedly installed on the ribs by screws A8, a main truss lower chord 9 welded to the top of the supporting column 1, double-layer steel folding pieces 3 welded and fixed at both ends of the main truss lower chord 9, the double-layer steel folding pieces 3 connected to the top of the flashing 4 by screws B303, and the bottom end of the flashing 4 fixedly connected to the galvanized steel folding pieces 5 by rivets 6.

[0020] Example 1: The double-layer steel folding member 3 is fully welded to the outside of the lower chord 9 of the main truss, forming an integral cap that prevents rainwater from entering from the fixed end of the double-layer steel folding member 3 and the lower chord 9 of the main truss. The top of the flashing plate 4 is inserted into the area between the outer layer folding member 301 and the inner layer folding member 302, and is fixed with screws B303. A waterproof gasket made of aluminum-zinc coated steel is placed at the contact end of the screws B303 and the outer layer folding member 301. The flashing plate 4 is used to cover the area where the supporting column 1 penetrates the corrosion-resistant roof panel 7. At the same time, the flashing plate 4 A water-retaining fold is provided on one side of the bottom end. The water-retaining fold is fixed to the corrosion-resistant roof panel 7 by galvanized steel folding piece 5 on the inside of the water-retaining fold, which is used to fix the lower end of the flashing 4. The corrosion-resistant roof panel 7 has an opening to accommodate the insertion of the support column 1. The soft waterproof layer 2 is set above the contact surface between the opening and the support column 1. The soft waterproof layer 2 includes waterproof coating A, waterproof cloth A, waterproof coating B, waterproof cloth B and waterproof coating C applied from bottom to top. The waterproof coatings A and B are polyurethane waterproof coatings, and the waterproof cloths A, B and C are non-woven fabrics.

The flashing plate 4 is inserted between the outer folding member 301 and the inner folding member 302. The top of the outer folding member 301 is welded and fixed to the outer surface of the lower chord of the main truss 9. The top of the flashing plate 4 is inserted in the middle of the double-layer steel folding member 3, which can provide waterproof protection for the top of the flashing plate 4 and effectively fix it with screws.

[0022] In the preferred technical solution, the flashing 4 is located on the outer side above the supporting column 1. The bottom end of the flashing 4 is integrally formed with a water-retaining fold. The top of the galvanized steel fold 5 is fixed to the inner side of the water-retaining fold. The water-retaining fold is used to guide rainwater to slide down to the corrosion-resistant roof panel 7, reducing the probability of rainwater contacting the galvanized steel fold 5.

[0023] In the preferred technical solution, the welding point between the outer layer folding member 301 and the lower chord of the main truss 9 is located at one-third of the diameter height of the circumference of the lower chord of the main truss 9. Setting the welding point at one-third of the diameter height makes it easier for the double-layer steel folding member 3 to support the lower chord of the main truss 9 in a better direction of force.
