Description

Technical Field

[0001] The utility model belongs to the technical field of high-altitude construction platforms, and in particular relates to a high-altitude large-span structural construction platform. Background Art

[0002] In recent years, with the development of urban construction, architects have given full play to their ingenuity, combining architectural shapes with their functional use, and designed many buildings with a sense of design. The design of the outdoor corridor of a unit-type high-rise residential building is a building product with great visual impact created by architects on the basis of fully considering the building's access, lighting, anti-theft and other functional and fire protection requirements, combined with the building's plane and facade shapes. However, although these design-conscious shapes and structures have a strong visual impact, they also bring great challenges to engineering construction. For high-rise buildings, construction workers need to work at high altitudes for a longer time, so the requirements for high-altitude construction platforms are higher, especially large-span construction platforms. Due to the large air flow at high altitudes, the platform is prone to shaking, which greatly affects construction safety and is not conducive to the work of construction workers. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] like Figures 1 to 3 As shown, the utility model is a high-altitude large-span structural construction platform, including a working platform 1 and a fixed frame 2. The left and right ends of the working platform 1 are connecting ends. Adjacent working platforms 1 are connected to each other through the connecting ends to form a large-span working platform. The working platform 1 is supported on the fixed frame 2.

[0020] A vertically arranged guardrail 3 is fixed on the windward surface of both sides of the working platform 1, and the tops of the guardrails on both sides are connected by a top bracket 7, so that the working platform 1, the guardrail and the top bracket 7 enclose a protection area for protecting the construction personnel, and a fixing plate 4 protruding horizontally outward is fixed in the middle of the outer side of the guardrail 3, and a windproof device 5 is installed outside the guardrails 3 on both sides, and the windproof device 5 includes a conical plate 51, a wind guide device and a spoiler device. The middle of the inner side of the conical plate 51 is installed on the fixing plate 4, and the upper and lower ends are fixedly connected to the upper and lower sides of the guardrail 3 through a fixing rod 6, so that the middle and both ends of the conical plate 51 are fixed to prevent the conical plate 51 from shaking;

[0021] The middle part of the outer side surface of the conical plate 51 is provided with an outwardly protruding, horizontally arranged tip constituting an airflow cutting portion. The outer side surface of the conical plate 51 is symmetrically provided with an arc-shaped guide portion with the airflow cutting portion as the central axis. The airflow blowing toward the conical plate 51 is first diverted by the airflow cutting portion, and then flows to the guide portions on both sides of the conical plate 51. Wind guiding devices and spoiler devices are sequentially arranged on the guide portions of the conical plate 51 along the airflow flow direction; the airflow flow direction mentioned here refers to the direction in which the airflow on both sides flows with the airflow cutting portion as the starting point toward the side away from the airflow cutting portion, respectively, along the upper and lower guide portions. The windward side mentioned below refers to the side facing the airflow direction when the airflow flows in the guide portion.

[0022] The wind guiding device includes a plurality of ventilation slots 52 extending along the airflow direction arranged on the conical plate 51, the ventilation slots 52 do not penetrate the conical plate 51, and the plurality of ventilation slots 52 are evenly arranged in the horizontal direction, and an air collecting tube 53 is installed on the ventilation slot 52, the air collecting tube 53 is provided with an air inlet on the windward side, and an air outlet 54 on the leeward side, and the air outlet of the air collecting tube is connected with the ventilation slot, and a fan blade 58 is rotatably installed in the air collecting tube 53 and between the air inlet and the air outlet 54. Specifically, a bracket 55 is installed on the inner wall of the air collecting tube 53, and a bearing 56 is installed on the bracket 55 and in the center of the air collecting tube 53, and the fan blade 58 is connected to the bearing 56 through a rotating shaft 57. When the airflow flows toward the guide parts on both sides of the conical plate 51, a part of the airflow enters the air collecting tube 53, and at this time, the fan blade 58 is rotated under force to slow down the airflow velocity, and the airflow enters from the air inlet and is discharged from the air outlet 54.

[0023] like Figures 1 to 4 As shown, the spoiler device includes a plurality of spoilers 8, which are evenly arranged in the horizontal direction. The windward side of the spoiler 8 is hinged on the conical plate 51, and the other side of the spoiler 8 is connected to the conical plate 51 through a spring 9. The spring 9 acts as a force unloading device so that the force of the airflow will not blow directly to the conical plate 51, thereby disrupting the airflow on both sides of the conical plate 51.

[0024] The working process of the above scheme is as follows: when the airflow blows toward the conical plate 51, the airflow is separated by the conical plate 51 and flows to both sides of the conical plate 51. A part of the airflow enters the air collecting tube 53, at which time the fan blades 58 are forced to rotate to slow down the airflow velocity, and the airflow enters the air outlet 54 and is discharged from the air outlet 54. When the other part of the airflow passes through the spoiler 8, the spring 9 is compressed by force, and at this time the airflow is disturbed by the spoiler 8.

[0025] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
