Description

Building design structure for efficiently draining roof rainwater Technical Field The utility model relates to the technical field of roof rainwater drainage, in particular to a building design structure for efficiently draining roof rainwater. Background In modern architectural design, roof drainage system bears the vital effect, and its core function lies in time, high-efficient liquid precipitation such as rainwater, snow water with the roof is discharged, prevents the production of roofing ponding phenomenon to effectively avoid ponding to cause erosion and damage to roof structure, guarantee the life and the security of building. At present, most roof drainage systems mainly rely on drainage pipelines to realize a rainwater drainage function, and in order to prevent leaves, sundries and the like from blocking the drainage pipelines, a filter mechanism such as a filter plate is usually arranged inside the drainage pipelines. However, this conventional design has obvious technical drawbacks. With the increase of the service time, the filter mechanisms such as the filter plates and the like are inevitably blocked due to the interception of a large amount of sundries, so that the drainage efficiency is affected. When maintaining the filter mechanism that blocks up, the operating personnel often need consume a large amount of time and energy and take out parts such as filter plate, and not only operation flow is loaded down with trivial details, has certain potential safety hazard moreover. More troublesome is, under the most urgent circumstances of drainage demands such as sleet weather, once take out the filter plate and clear stifled operation, leaf, debris etc. of being filtered the interception just can flow into the drain pipe along with the rainwater together, leads to downstream pipeline jam risk to increase very much. At this time, the drainage system cannot play an effective filtering role, so that the problems of unsmooth drainage, accumulated water and the like are difficult to be fundamentally solved. Therefore, the existing roof drainage technology needs to be further optimized and perfected to meet the drainage requirements of modern buildings. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a building design structure for efficiently draining roof rainwater, which solves the problems in the background art. The scheme for solving the technical problems is as follows: a building design structure for efficiently draining roof rainwater comprises a drain pipe and a connecting pipe; a connecting pipe is sleeved in the drain pipe in a sliding manner, and a limiting elastic piece is arranged in the connecting pipe; the connecting pipe is internally sheathed with a first filter screen box and a second filter screen box in a sliding way, and the two ends of the first filter screen box and the second filter screen box are respectively provided with an installation elastic sheet. On the basis of the technical scheme, the utility model can be improved as follows. Further, the connecting pipe is welded with a supporting frame, and the connecting pipe is installed on the drain pipe in a limiting mode through the supporting frame. The beneficial effects of adopting the further scheme are as follows: The setting of support frame provides stable bearing structure for the connecting pipe, ensures that the connecting pipe is in reasonable and firm position in the drain pipe, avoids taking place the skew or rocking because of external force effects such as rainwash lead to the connecting pipe to guarantee that the rainwater can get into the drain pipe from the connecting pipe smoothly, maintain drainage system's normal operating. Meanwhile, the limiting installation mode enables the connecting pipe and the drain pipe to form a sliding connection relationship, and when the inner assembly of the connecting pipe needs to be overhauled and replaced, the connecting pipe is conveniently pulled out of the drain pipe, and the convenience of maintenance is greatly improved. Further, the support frames are provided with six in total, and the six support frames are distributed in an annular exhibition mode relative to the circle centers of the connecting pipes. The beneficial effects of adopting the further scheme are as follows: Six support frames are annular and distributed, can provide even holding power to the connecting pipe from a plurality of directions, compare support frames that quantity is less or distribute unreasonably, and this kind of overall arrangement has strengthened the stability of connecting pipe in the drain pipe notably. Under the conditions of larger rainwater flow and enhanced water flow impact force, the annular distributed supporting frames can effectively disperse the acting force of water flow on the connecting pipe. Further, the two ends of the limiting elastic piece are welded with second connecting blocks, and the second connecting blocks are
