Description

Technical Field

[0001] The utility model relates to the technical field of building rain sheds, in particular to a large glass rain shed system used on a glass curtain wall. Background Art

[0002] At present, with the continuous development of the glass curtain wall field, glass curtain walls are being used more and more widely. In order to improve the waterproof and rainproof performance of the glass curtain wall structure, a canopy is set on the glass curtain wall structure. The canopy is a kind of building assembly set above the entrance and exit of the building or the top balcony to block rain, wind, and prevent high-altitude falling objects from hitting. In the prior art, the installation form of the canopy structure on the glass curtain wall is mainly to directly weld the canopy keel to the column of the glass curtain wall.

[0003] When using existing canopies for glass curtain walls, the installation method is generally to fix the connecting claws on the steel frame, and then fix the glass on the connecting claws with stainless steel bolts; this installation method requires pre-punching holes in the glass. In order to avoid glass breakage or loose bolt connection, the glass punching process requires high-precision professional equipment, and the punching process is time-consuming and costly; moreover, during installation, the welding position of the connecting claws needs to be continuously adjusted according to the holes on the glass to ensure that the subsequent stainless steel bolts pass through the holes and connect with the connecting claws, resulting in low installation efficiency and high installation cost.

[0004] In view of the above problems, the applicant provides a large glass canopy system for glass curtain walls which is easy and quick to install. Utility Model Content

[0005] The utility model aims to provide a large glass canopy system for a glass curtain wall, so as to solve the problems of low installation efficiency and high cost of the existing glass canopy.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a large glass canopy system for a glass curtain wall, comprising a supporting structure and a canopy tempered glass installed above the supporting structure, the supporting structure comprising a cantilever keel connected to a glass curtain wall column and a horizontal keel perpendicular to the cantilever keel, the canopy tempered glass is fixed to the cantilever keel at one end away from the glass curtain wall through a connecting unit, the connecting unit comprises a pressing block and an aluminum alloy auxiliary frame, the pressing block and the aluminum alloy auxiliary frame are detachably connected, and a silicone structural adhesive is provided between the aluminum alloy auxiliary frame and the canopy tempered glass.

[0007] The principles and advantages of this solution are:

[0008] 1. In actual application, the utility model uses a connection unit instead of a docking claw to connect and fix the cantilever keel with the canopy tempered glass, wherein the connection unit includes an aluminum alloy auxiliary frame and a pressure block, the aluminum alloy auxiliary frame is pressed and fixed on the cantilever keel by the pressure block, and the canopy tempered glass is fixed to the aluminum alloy auxiliary frame by a silicone structural adhesive, so that the canopy tempered glass does not need to be pre-punched, which reduces the material cost and processing cost; secondly, during installation, compared with the use of docking claws to connect, which requires repeated adjustment of the installation position according to the glass holes, the installation process using the connection unit is relatively simple, and the construction personnel can easily master it after training. The glass is pre-installed on the auxiliary frame, and then hoisted as a whole to the cantilever steel pipe for fixation, which simplifies the complexity of high-altitude operations, improves construction efficiency, and reduces safety risks.

[0009] 2. The frame-attached connection structure of the connection unit in the utility model is a mature technical solution in the glass curtain wall industry, which has the characteristics of standardization. Applying it to the glass canopy can make full use of the existing design specifications, material supply, construction technology and quality control system, reduce the complexity of design and construction, and improve work efficiency; at the same time, the frame-attached connection structure can effectively disperse the glass load and enhance the overall structural stability of the canopy. Especially for large-sized or heavy glass, the frame-attached connection structure can ensure that the glass is firmly installed and prevent the glass from shifting or breaking due to factors such as wind load and deadweight.

[0010] 3. The connection unit in the utility model makes the glass canopy system design simple and smooth, which is coordinated with the modern architectural style. The hidden sealing design can reduce the exposure of the connecting parts, keep the appearance of the canopy neat and uniform, and enhance the overall visual effect of the building; at the same time, the connection unit allows the single glass to be disassembled independently without large-scale adjustments to the entire canopy structure, reducing maintenance costs and time.

[0011] Furthermore, a positioning groove is provided on one side of the aluminum alloy auxiliary frame that contacts the pressing block, and positioning protrusions that match the positioning groove are provided on both sides of the pressing block.

[0012] The positioning grooves and positioning protrusions cooperate to enable each pressure block to quickly and accurately determine the installation position, without the need for construction personnel to rely on experience to make judgments. Each pressure plate is arranged in a straight line between the two aluminum alloy auxiliary frames, making the aluminum alloy auxiliary frames more stable under pressure, greatly improving construction efficiency and speeding up the overall construction progress. At the same time, the positioning grooves and positioning protrusions cooperate to make the pressure plate and the aluminum alloy auxiliary frames on both sides more tightly connected, effectively preventing the connection failure due to thermal expansion and contraction after long-term use.

[0013] Furthermore, the bottom of one end of the cantilevered keel close to the glass curtain wall is recessed inwards to form a step shape.

[0014] The above arrangement allows the cantilever keel to be placed on the crossbeam at one end close to the glass curtain wall. The crossbeam's support for the cantilever keel effectively reduces the stress stretching caused by the suspension at the welding structure between the cantilever keel and the column, making the cantilever keel connection more stable and firm, thereby improving the overall stability of the glass canopy system.

[0015] Furthermore, the upper surface of the cantilevered keel is an inclined surface, and the end of the inclined surface close to the glass curtain wall is a higher end.

[0016] The above arrangement makes the tempered glass of the canopy have an overall tilt angle after installation, so that rain and snow slide down along the tilt angle, thereby preventing rain and snow from accumulating on the canopy in rainy and snowy weather, causing excessive pressure on the canopy and increasing the risk of collapse.

[0017] Furthermore, the outer sides of the cantilever keel and the horizontal keel are sheathed with stainless steel rectangular tubes.

[0018] Stainless steel rectangular tubes can effectively prevent cantilever keels and horizontal keels from being corroded by corrosive substances such as acids, alkalis, chemicals, and external oxidation, making the overall supporting structure more stable and longer in service life.

[0019] Furthermore, a sealing unit is provided between two adjacent canopy tempered glasses, and the sealing unit comprises a foam rod and a silicone weather-resistant sealant.

[0020] Providing a sealing unit at the connection of the two canopy tempered glasses is beneficial to increasing the overall connectivity and sealing of the structure, while making the transition of the connection smoother and improving the appearance of the entire glass canopy system.

[0021] Furthermore, a silicone weather-resistant sealant is provided between the canopy tempered glass and the curtain wall glass.

[0022] The above arrangement enables the gap between the canopy tempered glass and the curtain wall glass to be completely sealed, effectively preventing rainwater from dripping along the gap. BRIEF DESCRIPTION OF THE DRAWINGS
