Description

[0002] Glass curtain wall is a modern building exterior wall design, which uses large area of ​​glass panels to cover the building surface, forming a wall-like structure. It has the advantages of high lighting rate, natural transparency, atmospheric appearance, energy saving and environmental protection, etc., and is widely used in commercial, office and residential buildings. With the rapid development of construction technology and architectural aesthetics, glass curtain walls have gradually developed a trend of large size and large span, and their shape is more beautiful and atmospheric. However, large-span glass curtain walls also face many problems, such as difficult installation and easy deformation under temperature changes.

[0003] A Chinese patent application CN210947326U discloses a large-span glass curtain wall, the technical solution of which is as follows: it includes an aluminum alloy outer cover and an aluminum alloy decorative frame located below the aluminum alloy outer cover, a partition is fixedly arranged inside the aluminum alloy outer cover, an I-beam is fixedly connected between the partition and the top inner wall of the aluminum alloy outer cover, and hollow through grooves are symmetrically arranged on the partition, and machine screws are arranged in the hollow through grooves. A large-span glass curtain wall in this technology can ensure the safety and reliability of the entire force system structure, avoiding the problem that all loads of the large-span glass curtain wall in the prior art are transferred from the glass to the aluminum alloy frame through glue, resulting in loose connection and poor safety; and through the isolation of the insulation block interlayer, the heat transfer speed between the two tempered hollow glasses is delayed, effectively ensuring the thermal insulation of the glass curtain wall, so that the connection between the glass has better thermal insulation.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1: Figures 1 to 5 As shown, a large-span skylight roof glass installation device according to an embodiment of the present invention comprises:

[0039] A steel column 1, wherein a keel 2 is disposed on the side of the steel column 1; connecting plates matching the steel column 1 are disposed on both sides of the keel 2, and the connecting plates are fixedly connected to the keel 2 by a first bolt 3;

[0040] The inner pressure plate 4 is fixedly connected to both sides of the keel 2, and the two are an integrated structure; the inner pressure plate 4 is provided with an inner clamping portion 5 on the side thereof;

[0041] An outer pressure plate 6, with outer clamping parts 7 disposed on both sides of the outer pressure plate 6; the outer pressure plate 6 is fixedly connected to the keel 2 by a second bolt 8; a plug rod 9 is fixedly connected to the surface of the outer clamping part 7;

[0042] A glass plate 10, which is a two-layer or three-layer tempered hollow glass to improve the heat insulation and sound insulation performance; the glass plate 10 is installed between the outer clamping part 7 and the inner clamping part 5; a cushion sleeve 11 is provided between the outer clamping part 7 and the inner clamping part 5 and the glass plate 10; an elastic block 12 is fixedly connected inside the glass plate 10, and the material of the elastic block 12 can be rubber, silicone or other high elastic materials, and the elastic block 12 is prefabricated inside the glass plate 10; the elastic block 12, the cushion sleeve 11 and the inner clamping part 5 are all provided with a plug hole that cooperates with the plug rod 9;

[0043] In the prior art, when installing the large-span daylighting roof glass, the insertion rod 9 is inserted into the interior of the glass to further position and fix the glass. However, the insertion rod 9 and the glass are usually tightly matched, and no certain deformation space is reserved for the glass. Therefore, in the subsequent use process, the glass is prone to lateral deformation due to temperature changes, especially this type of large-span daylighting glass is often deformed to a large extent, which causes the glass to break or even explode under pressure. During installation, the present invention inserts the insertion rod 9 into the insertion holes of the elastic block 12, the cushion sleeve 11 and the inner clamping part 5, and uses the outer clamping part 7 and the inner clamping part 5 to clamp and fix the glass plate 10, so as to improve the positioning effect of the glass plate 10. In the subsequent use process, the elastic block 12 can play a buffering role and reserve a certain deformation space for the glass plate 10. When the glass plate 10 is laterally deformed due to temperature changes, one side of the elastic block 12 will be compressed, thereby absorbing and compensating for the dimensional change of the glass plate 10, preventing the glass plate 10 from being severely compressed and damaged, and extending its service life.

[0044] An elastic sealing strip 13 is arranged between the side of the glass plate 10 and the keel 2, and the material of the sealing strip 13 can be an elastic material such as rubber, silicone, latex, polyurethane, etc.; the sealing strip 13 and the outer pressure plate 6 are filled with sealant, such as silicone sealant, polysulfide rubber sealant, chloroprene rubber sealant and epoxy resin sealant, etc.; by setting the sealing strip 13 and filling the gap between the sealing strip 13 and the outer pressure plate 6 with sealant, the sealing effect of the device can be enhanced, and the overall waterproof, heat insulation and sound insulation performance of the lighting glass can be improved.

[0045] The elastic block 12 is designed to be a hollow structure; a group of first springs 14 are evenly distributed inside the elastic block 12; by providing a plurality of first springs 14, the anti-extrusion ability and recovery ability of the elastic block 12 are improved to prevent the elastic block 12 from being subjected to the lateral extrusion of the glass plate 10 for a long time, which may cause the elastic block 12 to be difficult to recover automatically.

[0046] A liquid capsule 15 is fixedly connected to the inner clamping part 5, and the liquid capsule 15 is prefabricated inside the inner clamping part 5; glue is stored in the liquid capsule 15; the end of the insertion rod 9 is designed to be sharp; a flow channel 16 is opened inside the insertion rod 9; a group of guide holes 17 are evenly distributed on the surface of the insertion rod 9 at the corresponding positions of the elastic block 12, and the guide holes 17 are connected to the flow channel 16; during the insertion of the insertion rod 9 into the inner clamping part 5, its tip can pierce the liquid capsule 15 and enter the liquid capsule 15, and then the glue in the liquid capsule 15 flows into the insertion rod 9 through the flow channel 16, and then flows along the multiple guide holes 17 to between the insertion rod 9 and the elastic block 12. On the one hand, the two are firmly bonded to improve stability, and on the other hand, the gap between the insertion rod 9 and the elastic block 12 can be blocked to prevent this gap from affecting the sound insulation, heat insulation and water insulation performance of the glass plate 10.

[0047] The blocking strip 13 is designed to be a hollow structure; a group of collecting tubes 18 and conduits 19 are fixedly connected to the surface of the blocking strip 13; the collecting tube 18 is designed to be inclined; one end of the collecting tube 18 is connected to the inside of the blocking strip 13, and the other end passes through the outer pressure plate 6; one end of the conduit 19 is connected to the inside of the blocking strip 13, and the other end passes through the outer clamping part 7 and faces the glass plate 10; when it rains in summer, rainwater can enter the inside of the blocking strip 13 through the collecting tube 18, thereby storing the rainwater, and then when the temperature rises subsequently, the moisture inside the blocking strip 13 can cool down the entire installation structure, and when the glass plate 10 expands laterally with the increase in temperature, the side of the glass plate 10 will squeeze the blocking strip 13, squeeze the rainwater inside it outward through multiple conduits 19, and spray it onto the surface of the glass plate 10, on the one hand, the glass plate 10 is washed to reduce the dust on its surface, and on the other hand, the glass plate 10 can be cooled to alleviate the degree of lateral expansion, further preventing it from being damaged by excessive deformation.

[0048] The sealing strip 13 is fixedly connected to a water storage part 20, and the water storage part 20 is made of a water-absorbing material, which can be a sponge, foam, cotton cloth or the like. By arranging the water storage part 20 inside the sealing strip 13, a certain water-fixing effect can be achieved. After absorbing water, the water storage part 20 can promote uniform distribution of water in its length direction, thereby preventing the water from being concentrated at the bottom of the sealing strip 13 under the action of gravity and causing uneven water spraying from different conduits 19.

[0049] Embodiment 2: Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a slide groove 21 is provided on the surface of the outer pressure plate 6 at a position corresponding to the collecting tube 18; a slide plate 22 is slidably connected inside the slide groove 21; a through groove 23 is provided inside the slide plate 22; a second spring 24 is fixedly connected between one end of the slide plate 22 and the slide groove 21, and a driving member 25 is fixedly connected between the other end and the slide groove 21; the driving member 25 is made of water-absorbing and swelling material, which can be swelling rubber, polymer hydrogel and other materials. After such materials absorb water and swell, as the water inside them gradually dries, their volume will gradually shrink and recover, thereby realizing the reuse of the driving member 25; under normal circumstances, the collecting tube 18 and the through groove 23 are misaligned with each other, and the collecting tube 18 is in a blocked state. When it rains, the rainwater soaks the driving member 25, and then the driving member 25 absorbs water, expands and stretches, pushing the slide plate 22 to slide inside the slide groove 21, and aligning the through groove 23 with the collecting tube 18. At this time, the rainwater can enter the sealing strip 13 along the through groove 23 and the collecting tube 18 for storage. After the rain stops and the sky clears, the driving member 25 gradually dries and shrinks to recover, and the second spring 24 pushes the slide plate 22 to reset and re-seal the collecting tube 18. On the one hand, it can prevent external dust and other debris from entering the sealing strip 13 through the collecting tube 18, and prevent the moisture inside the sealing strip 13 from evaporating and dissipating to the outside, thereby improving the storage effect of rainwater. On the other hand, when the glass plate 10 squeezes the sealing strip 13, the moisture inside it will not be squeezed out through the collecting tube 18, thereby improving the utilization rate of rainwater.

[0050] In this embodiment, in order to improve the water spraying effect of the conduit 19, a structure similar to a pressure valve can be set inside the conduit 19. When the glass plate 10 squeezes the sealing strip 13 to a certain extent, the pressure inside it is higher than the threshold of the pressure valve, and the conduit 19 is in a conductive state. At this time, the water spraying pressure can be increased when spraying water, and the glass plate 10 is further rinsed and cooled, thereby increasing the effective area of ​​the water flow.

[0051] The outer side of the slide plate 22 is provided with a groove 26; a collecting sheet 27 is arranged inside the groove 26; the bottom of the collecting sheet 27 is aligned with the bottom of the through slot 23 and is rotatably connected; an elastic rope 28 is fixedly connected between the collecting sheet 27 and the slide plate 22; a first magnetic block 29 is fixedly connected to the inner side of the outer pressure plate 6 at a position corresponding to the second spring 24; a second magnetic block 30 is fixedly connected to the top of the collecting sheet 27; the first magnetic block 29 and the second magnetic block 30 repel each other when they are close to each other; when the through slot 23 is aligned with the collecting tube 18, the second magnetic block 30 just moves to the first magnetic block 29, and then the first magnetic block 29 generates a repulsive force on the second magnetic block 30, pushing the collecting sheet 27 to flip outward, so that the collecting sheet 27 collects rainwater, and then the rainwater quickly flows along the inclined surface of the collecting sheet 27 to the inside of the through groove 23 and the collecting tube 18, thereby improving the efficiency of collecting rainwater. When the rain stops and the sky clears, the driving member 25 contracts and the slide plate 22 is reset, the first magnetic block 29 and the second magnetic block 30 move away from each other, and then the elastic rope 28 pulls the collecting sheet 27 into the groove 26, so that the collecting sheet 27 no longer protrudes from the surface of the slide plate 22, thereby maintaining the flatness and beauty of the lighting glass and preventing the collecting sheet 27 from scratching pedestrians outside the building.

[0052] like Figure 7 As shown, a method for installing a large-span skylight roof glass, the method adopts the large-span skylight roof glass installation device, and comprises the following steps:

[0053] S1: The keel 2 is fixedly mounted on the surface of the steel column 1 by means of the first bolt 3, and the cushion sleeves 11 are respectively mounted on the inner clamping part 5 and the outer clamping part 7;

[0054] S2: placing the glass plate 10 on the surface of the inner clamping portion 5 of the inner pressure plate 4 and installing the blocking strip 13 so that the blocking strip 13 is located between the side surface of the glass plate 10 and the keel 2;

[0055] S3: Press the outer clamping portion 7 of the outer pressure plate 6 onto the surface of the glass plate 10, and align the insertion rod 9 to be inserted into the elastic block 12 and the inner clamping portion 5, and fix the outer pressure plate 6 to the surface of the keel 2 by the second bolt 8;

[0056] S4: When the insertion rod 9 is inserted into the inner clamping part 5, the liquid capsule 15 is punctured and enters the liquid capsule 15, and then the glue in the liquid capsule 15 flows into the insertion rod 9 through the flow channel 16, and then flows along the multiple guide holes 17 to between the insertion rod 9 and the elastic block 12;

[0057] S5: Pour sealant between the sealing strip 13 and the outer pressure plate 6, and after it dries, check whether the connection between the components is stable.
