Technical Field

[0001] The utility model relates to the technical field of waterproof structures for connection nodes, in particular to a waterproof structure for the connection node between an outdoor ground glass daylighting roof and the ground. Background Technique

[0002] The domestic construction industry has developed rapidly. To date, a large number of glass curtain walls and glass curtain wall roof building designs and construction applications have brought new technologies and new materials for building energy conservation, and also brought new fields and new topics to engineering design and construction. In particular, the wide application of accessible glass daylighting roof surfaces has brought significant economic benefits to building natural lighting and energy conservation, while meeting the aesthetic requirements of buildings, and can meet the requirements of building safety, reliability, and service life.

[0003] In addition to permanent loads, the outdoor ground glass daylighting roof also undergoes anti-leakage under the condition of large live loads such as a large number of people all year round. Especially at the position where the glass daylighting roof meets the ground, materials such as sealant or rubber gaskets are usually used for sealing and waterproofing. After a short period of use, water leakage occurs at the edge where the ground glass daylighting roof meets the ground, and the subsequent waterproof measures cannot solve the fundamental problem, thus affecting the durability of the daylighting roof and the comfort of people indoors. Summary of the Invention

[0004] The purpose of the utility model is to provide a waterproof structure for the connection node between an outdoor ground glass daylighting roof and the ground, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A waterproof structure for the connection node between an outdoor ground glass daylighting roof and the ground, including a civil engineering structure arranged near the connection underground. The civil engineering structure forms an inclined slope radially outwards. An inner ring of the civil engineering structure is fixedly connected with a keel frame, and a glass panel is arranged on the keel frame;

[0007] It further includes a support frame arranged between the keel frame and the glass panel, and a gap is formed between the support frame and the civil engineering structure. The gap is filled with asphalt glue;

[0022] Hereinafter, various exemplary embodiments, features and aspects of the present application will be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0023] The special term "exemplary" here means "serving as an example, an embodiment or an illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments.

[0024] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the gist of the present application.

[0025] Please refer to Figures 1 to 2 , in the embodiment of the present utility model, the waterproof structure at the connection between the outdoor ground glass daylighting roof and the ground includes a civil engineering structure 15, a dragon skeleton 1, a glass panel 2, an asphalt adhesive 16, a waterproof coiled material 17, a cement mortar layer 18, and a support frame.

[0026] Specifically as follows, please refer to Figure 1 , Figure 2 , including;

[0027] A civil engineering structure 15 provided near the connection underground, the civil engineering structure 15 is formed with an inclined slope radially outward, an inner ring of the civil engineering structure 15 is fixedly connected with a dragon skeleton 1, and a glass panel 2 is arranged on the dragon skeleton 1;

[0028] It further includes a support frame disposed between the keel frame 1 and the glass panel 2, and a gap is formed between the support frame and the civil engineering structure 15, and the gap is filled with asphalt glue 16;

[0029] A waterproof coiled material 17 is laid on one side of the support frame and the civil engineering structure 15, and a cement mortar layer 18 is poured on the side of the waterproof coiled material 17 away from the civil engineering structure 15 and the support frame.

[0030] Specifically, in this embodiment, the waterproof structure at the joint between the outdoor ground glass daylighting roof and the ground described in the present utility model is adopted. During use, through the setting of the support frame and the keel frame 1, while ensuring the connection stability, it can avoid deformation under the superposition of long-term dead load and live load. At the same time, the gap between the support frame and the civil engineering structure 15 is filled with asphalt glue 16. Because the asphalt glue 16 itself has elasticity, even when the position between the support frame and the civil engineering structure 15 is offset due to deformation, it will not affect the waterproofing of the asphalt glue 16.

[0031] For a further solution of this utility model, please refer to Figure 1 The support frame includes a first steel plate 10 fixedly connected to the keel frame 1. The first steel plate 10 is arranged along the axial direction of the keel frame 1, and a fourth steel plate 14 is fixedly installed radially outward on the first steel plate 10. The gap is formed between the first steel plate 10 and the civil engineering structure 15.

[0032] When installing the support frame, it is mainly divided into two steps; first, a first steel plate 10 with a suitable thickness is welded around the keel frame 1, and anti-corrosion treatment is performed after welding; second, a fourth steel plate 14 with the same thickness is welded around the first steel plate 10, and the weld height is not less than the thickness of the steel plate, and anti-corrosion treatment is performed after welding;

[0033] It should be noted that in order to improve the construction efficiency, the first steel plate 10 and the fourth steel plate 14 can be welded in the factory.

[0034] Preferably, a profile 3 is detachably installed on the keel frame 1 along the axial direction, and the profile 3 is made of aluminum alloy material.

[0035] Wherein, through holes are formed on the profile 3, and bolts 4 are threadedly connected in the through holes. One end of the bolt 4 away from the profile 3 penetrates the keel frame 1 and is threadedly connected to the keel frame 1.

[0036] It should be noted that a first cushion block 5 is arranged between the profile 3 and the keel frame 1.

[0037] During construction, the profile 3 can be placed on the keel frame 1. A first spacer 5 made of continuous rigid EPDM is used between the keel frame 1 and the profile 3, and then the profile 3 is firmly fixed to the keel frame 1 with machine countersunk bolts 4.

[0038] A double-sided tape 6 is adhered to the profile 3, and one side of the double-sided tape 6 away from the profile 3 is adhered to the glass panel 2.

[0039] Preferably, the double-sided tape 6 is an EVA double-sided tape. The EVA double-sided tape has more excellent weather resistance, chemical resistance, buffering property, sealing property and superior adhesiveness than ordinary double-sided tapes. At the same time, it has good resilience and high tensile strength, and has good shockproof and buffering performance.

[0040] Through the detachable connection between the profile 3 and the keel frame 1, the direct contact between the glass panel 2 and the keel frame 1 can be avoided, and under the action of the double-sided tape 6, the buffering effect between the profile 3 and the glass panel 2 can be improved.

[0041] As a further solution of the present utility model, please refer to Figure 1 , a second spacer 8 is inserted between the glass panel 2 and the first steel plate 10, and both sides of the second spacer 8 are respectively abutted against the glass panel 2 and the first steel plate 10.

[0042] Preferably, the second spacer 8 is made of EPDM material.

[0043] The glass panel 2 is fixedly connected radially outward with a third steel plate 12. A second steel plate 11 is fixedly installed on the third steel plate 12, and a first sealant 9 is filled in the gap between the second steel plate 11 and the glass panel 2.

[0044] During construction, after the glass panel 2 arrives at the site, the double-sided tape 6 is adhered to the profile 3. The bottom surface of the glass panel 2 is first fully filled with component structural adhesive 7, and then the glass panel 2 is laid flat with a suction cup to position the glass panel 2. The second spacer 8 is inserted around the glass panel 2 for limiting, and the one-component structural adhesive 7 is injected for the second time, and then the first sealant 9 is used for caulking. After the above steps are completed, the first waterproof measure for the ground glass daylighting roof and the civil engineering structure 15 has been completed.

[0045] Under normal circumstances, the design unit or the construction unit will use stainless steel plates or aluminum plates for edge sealing treatment with the glass. The stainless steel plates are too thin and are prone to deformation when welded to carbon steel, and the shape and size are not easy to guarantee. If aluminum plates are used, due to their lower strength than steel plates, they are prone to deformation under the long-term superposition of self-weight load and live load. In addition, the aluminum plates need to be fixed with screws, and the screws penetrate the profile 3, and there will be a potential water leakage hazard in the future.

[0046] As a further solution of the present utility model, please refer to Figure 1, a third steel plate 12 is fixedly connected to the glass panel 2 along the radial direction outward, a second steel plate 11 is fixedly installed on the third steel plate 12, and a first sealant 9 is filled in the gap between the second steel plate 11 and the glass panel 2.

[0047] To avoid the edge of the glass panel 2 being damaged due to the collision of the later floor tiles during laying, a second steel plate 11 made of ordinary and stainless steel material is used for isolation. The second steel plate 11 is welded and fixed on the third steel plate 12, and the gap between the second steel plate 11 and the glass panel 2 is sealed with a first sealant 9.

[0048] Preferably, there is a gap between the second steel plate 11 and the floor tile 19, and this gap is filled with a second sealant 13.

[0049] In the second waterproof measure of the ground glass daylighting roof and the civil engineering structure 15, a waterproof coiled material 17 made of ethylene propylene diene monomer (EPDM) rubber waterproof material is bonded to one side of the first steel plate 10, the third steel plate 12 and the fourth steel plate 14, and the other end of the waterproof coiled material 17 is overlapped with the waterproof coiled material pressed on the civil engineering structure 15.

[0050] After the waterproof coiled material 17 is laid, a cement mortar layer 18 is used for the third waterproofing, and then the floor tile 19 is laid.

[0051] Compared with the prior art, the present utility model adopts a multi-layer waterproof system. The first layer is hot-dip galvanized steel plate plus asphalt hemp thread glue waterproofing, the second layer is ethylene propylene diene monomer (EPDM) waterproof coiled material, and the third layer is waterproof mortar. The three-layer waterproofing and three-layer protection improve the weather resistance and durability of the waterproof joints, extend the service life of the building, and the optimized drainage design reduces the possibility of water accumulation and leakage.

[0052] Generally speaking, a rigid waterproof and a flexible waterproof two-layer waterproof system are combined, and a joint design including two sets of systems is adopted to better solve the waterproof treatment at the joints between the glass and the steel structure and between the glass and the concrete floor. Thereby improving the weather resistance and durability of the waterproof joints.

[0053] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0054] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
