Description

Technical Field

[0001] This invention relates to the field of old factory building renovation technology, specifically to a skylight installation node for adding a new skylight to the roof of an old factory building and its construction process. Background Technology

[0002] With the development of society and economy, the continuous advancement of urbanization, and the ongoing implementation of the concept of urban renewal, more and more old factories are facing renovation and transformation. However, the architectural form of old factories has inherent defects compared to the present, the most important of which is the large net height inside the factory buildings and the small total building height. If no additions are made, they can only be used as single-story buildings, resulting in a significant waste of space. If additions are made, the function of use needs to be changed, and the standards will change accordingly.

[0003] When changing the function of a building, lighting and fire protection are extremely important acceptance criteria for ensuring safety and comfort. Considering that the original factory building only has door and window openings in the perimeter walls, it would be difficult to ensure lighting and fire protection if only these existing openings were used, and the building layout would be significantly restricted. Taking into account the actual conditions of the old factory building and current needs, the idea of ​​adding skylights to the roof of the original factory building can solve the above problems simultaneously, and has good application and promotion value.

[0004] During the process of adding skylights, due to the prestress in the original structural beams and roof panels, it is impossible to directly install rebar or install embedded parts.

[0005] Therefore, this invention is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a skylight installation node and construction process for adding a skylight to the roof of an old factory building, so as to solve the technical problems existing in the prior art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: a skylight installation node for adding a skylight to the roof of an old factory building, comprising: a roof panel with an opening; a main keel on the rib of the roof panel, the main keel being arranged around the inner perimeter of the opening, and multiple supporting keels arranged along the width of the main keel; a lower flange plate on the main keel, the lower flange plate having two slots, the rib being surrounded by a U-shaped connecting plate, and the two ends of the U-shaped connecting plate passing through the two slots respectively, the two ends of the U-shaped connecting plate being flatly welded to the upper surface of the lower flange plate to form the weld points.

[0008] In an optional embodiment, multiple supporting keels are arranged in parallel, and the two ends of each supporting keel are respectively welded to the lower flange plate of the main keel.

[0009] In an optional embodiment, the spacing between the multiple parallel supporting keels is 500mm.

[0010] In an optional embodiment, the main keel is an I-beam, and the main keel is also provided with an upper flange plate.

[0011] In an optional embodiment, the internal shape of the U-shaped connecting plate matches and fits the external shape of the plate rib.

[0012] In an optional embodiment, a vertical keel is welded above the upper flange plate of the main keel, and a longitudinal keel and a transverse keel are welded above the vertical keel.

[0013] In an optional embodiment, a skylight is provided above the longitudinal keel and the transverse keel.

[0014] In an optional embodiment, the area around the skylight is sealed with adhesive between it and the decorative layer, and the area around the vertical keel is sealed with cement pressure board.

[0015] Another technical solution adopted in this invention is: a construction process for adding skylight installation nodes to the roof of an old factory building as described above, comprising the following steps:

[0016] S1: Remove the roof panel to form the opening, while retaining the rib in the roof panel located at the opening;

[0017] S2: Grooves are cut into the lower flange plate of the main keel to form symmetrically arranged slots, and the main keel is placed around the opening and placed on the plate rib.

[0018] S3: Weld multiple supporting keels in parallel between the main keels;

[0019] S4: After the U-shaped connecting plate surrounds the plate rib, the two ends of the U-shaped connecting plate pass through the slot of the main keel and are flatly welded to the upper surface of the lower flange plate.

[0020] S5: Weld vertical keels above the upper flange plate of the main keel, and install longitudinal and transverse keels above the vertical keels.

[0021] S6: Install a skylight above the longitudinal and transverse keels.

[0022] In an optional embodiment, in S5, the vertical keel is perpendicular to the ground, and the skylight is installed horizontally by adjusting the length of the vertical keel.

[0023] The beneficial effects of this invention are as follows:

[0024] (1) The U-shaped connector in the node device is connected to the original roof rib in a similar manner as a clamp, and forms a support relationship with the rib that can slide relative to each other. When the structure is subjected to stress changes and settlement occurs or the old and new structures are displaced, it plays a role in reducing internal stress and preventing squeezing damage between the old and new structures (skylight system and rib).

[0025] (2) The node device has two symmetrical slots on the lower flange plate of the main keel. The two ends of the U-shaped connector pass through the slots and are flat-welded to the upper surface of the lower flange plate of the main keel. If the slots are not made, the welding method is overhead welding, which greatly reduces the welding difficulty, helps to ensure quality, avoids high-altitude operations, and is also conducive to construction safety.

[0036] Example 1

[0037] Please see the appendix Figure 1-5 The purpose of this embodiment is to provide a new skylight installation node for an old factory roof, including: a roof panel 1, with an opening 3 on the roof panel 1; a main keel 2 is provided on the ribs 6 of the roof panel 1, the main keel 2 is provided around the inner perimeter of the opening 3, and multiple supporting keels 4 are provided along the width direction of the main keel 2, the multiple supporting keels 4 are arranged in parallel, preferably, the spacing between the multiple parallel supporting keels 4 is 500mm, and the two ends of each supporting keel 4 are respectively welded to the lower flange plate 22 of the main keel 2. To ensure that the skylight system meets the stress requirements, the supporting keel is made of 50×50×5.0 steel pipe.

[0038] Specifically, the main keel 2 is an I-beam, and it has a lower flange plate 22 and an upper flange plate 21. The main keel 2 is HW125×125×6.5×9mm. The lower flange plate 22 has two slots 7, each 54mm wide, to allow the U-shaped connecting plate 5 to pass through. The plate rib 6 is surrounded by the U-shaped connecting plate 5, with each end of the U-shaped connecting plate 5 passing through one of the two slots 7. The ends of the U-shaped connecting plate 5 are flatly welded to the upper surface of the lower flange plate 22 to form weld points 8. In this embodiment, the U-shaped connecting plate 5 is made of 5mm thick steel plate bent into shape. It should be noted that the internal shape of the U-shaped connecting plate 5 matches and fits the external shape of the plate rib 6. Through the above structure, the U-shaped connecting plate 5 is connected to the old structure (plate rib) in a clamp-like manner (without steel adhesive), which solves the mechanical transmission problem between the new and old structures. Furthermore, the clamp-like connection eliminates the hidden danger of relative displacement caused by different materials and additional loads in the new and old structures, thus ensuring the stability of the new sunroof system.

[0039] Furthermore, a vertical keel 9 is welded above the upper flange plate 21 of the main keel 2. The vertical keel 9 is made of 100×50×5.0mm steel pipe with a spacing of 500mm. The vertical keel 9 must be installed perpendicular to the ground, and the skylight is ensured to be installed horizontally by adjusting the length of the vertical keel 9. A longitudinal keel 12 and a transverse keel 10 are welded above the vertical keel 9. The skylight 11 is installed above the longitudinal keel 12 and the transverse keel 10, where the transverse keel is made of 50×50×5.0mm steel pipe. The longitudinal keel 12 and the transverse keel 10 are the supporting components that are in direct contact with the skylight, and they must be installed horizontally.

[0040] In addition, the skylight 11 is sealed with adhesive around its perimeter and the decorative layer, while the vertical keel 9 is sealed with cement pressure board around its perimeter. The skylight 11 must exceed the dimensions of the horizontal keel 10 and the vertical keel 12 to prevent rainwater seepage, and the skylight 11 is sealed with adhesive around its perimeter and the surrounding decorative layer. The vertical keel 9 is sealed with double-layered, double-sided cement pressure board + 80mm thick rock wool around its perimeter, and the decorative layer is applied after the outer waterproofing reaches the flashing height.

[0041] Example 2

[0042] Please see the appendix Figure 1-5 The purpose of this embodiment is to provide a construction process for adding skylight installation nodes to the roof of an old factory building, characterized by the following steps:

[0043] S1: Remove roof panel 1 to form opening 3, and retain the rib 6 in roof panel 1 located at opening 3;

[0044] For the portion of the roof panel 1 to be partially removed, manual chiseling will be used to chisel along the large and small trapezoidal ribs of the precast roof panel. During the chiseling process, only the reinforcing steel at the opening 3 will be cut; cutting the reinforcing steel of the trapezoidal ribs is strictly prohibited. The reinforcing steel and concrete near the trapezoidal rib 6 will be removed and ground using an angle grinder, ensuring that the edges meet the requirements of the decorative base layer without damaging the trapezoidal rib 6.

[0045] S2: Grooves are cut into the lower flange plate 22 of the main keel 2 to form symmetrically arranged slots 7. The main keel 2 is then placed around the opening 3, and rests on the rib 6. At this stage, the main keel 2 is placed on the rib 6 of the original roof 1. Because there is a height difference between the roof panel 1 and the rib 6, temporary fixing is not required. Before installation, grooves are cut into the lower flange plate 22 according to the position of the rib 6. The grooves 7 are 54mm wide to allow the U-shaped connecting plate 5 to pass through the lower flange plate 22 of the main keel.

[0046] S3: Multiple supporting keels 4 are welded in parallel between the main keels 2, and the two sides of the supporting keels 4 are welded to the lower flange plate 22 of the main keel 2.

[0047] S4: After the U-shaped connecting plate 5 surrounds the rib 6, the two ends of the U-shaped connecting plate 5 pass through the slots 7 of the main keel 2 and are flatly welded to the upper surface of the lower flange plate 22. The U-shaped connecting plate 5 is made of 5mm thick steel plate bent into shape. If the slots 7 are not made, the welding method is overhead welding. Flat welding greatly reduces the welding difficulty, which is conducive to ensuring quality, avoiding high-altitude operations, and also conducive to construction safety. In addition, the U-shaped connecting piece 5 is connected to the rib 6 of the original roof 1 in a similar manner to a clamp, and forms a relatively sliding support relationship with the rib 6. When the structure experiences settlement due to changes in stress or displacement between the old and new structures, it plays a role in mitigating internal stress and preventing squeezing damage between the old and new structures.

[0048] S5: Weld vertical keel 9 above the upper flange plate 21 of the main keel 2. The installation of vertical keel 9 must ensure that it is perpendicular to the ground. Adjust the length of vertical keel 9 to ensure that the skylight 11 is installed horizontally. Install longitudinal keel 12 and transverse keel 10 above vertical keel 9.

[0049] S6: Install the skylight 11 above the longitudinal keel 12 and the transverse keel 10. The transverse keel 10 and the longitudinal keel 12 are the supporting components that are in direct contact with the skylight 11. When installing, it must be ensured that they are level.

[0050] S7: After installing the skylight system frame according to the above steps, install the skylight 11 and its surrounding enclosure system. The skylight 11 must exceed the dimensions of the horizontal frame 10 and the vertical frame 12 to prevent rainwater seepage. Seal the skylight 11 to the surrounding decorative layer using adhesive injection. Seal the vertical frame 9 around its perimeter with double-layered, double-sided cement pressure board 13 + 80mm thick rock wool. After waterproofing the outer side to the desired level, proceed with the decorative layer construction. It is worth noting that the skylight 11 is larger than the opening 3 and the frame dimensions, and the adhesive injection method used to seal the skylight 11 to the cement pressure board 13 decorative layer enhances the waterproofing effect of the skylight 11.

[0051] Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention shall be included within the scope of protection of this invention.
