Description

Deformation joint structure for building roof

Technical Field

The utility model relates to a general building structure for joints, in particular to a deformation joint structure for a building roof.

Background

As shown in fig. 1, in the building engineering, because the direction of the roof deformation joint is not perpendicular to the direction of the roof slope-finding drainage, the water diversion line 201 is the highest point of the roof, and the drainage ditch 202 is at the lowest point of the roof, in the prior art, as shown in fig. 2, no matter a metal cover plate or a deformation joint structural form of a reinforced concrete cover plate is adopted, the elevation of the cover plate 203 always needs to be higher than the elevation of the roof building, so that the deformation joint 204 can have the waterproof effect.

Because the outdoor roof belongs to the non-volumetric area of the building, in large-scale building engineering, the floor area of the roof is wide, and the space integrity can be used for the expansion of communication activities such as commercial outer ornaments, sightseeing, exhibitions and the like, thereby being beneficial to improving the interactivity, the utilization rate and the invisible value of the building. The deformation joint structure of the roof of the building can damage the effective activity space of the roof due to the fact that the cover plate of the deformation joint is higher than the roof, and therefore the building availability is reduced.

In order to overcome the defects, as shown in fig. 3, the existing roof deformation joint extends to a direction perpendicular to roof slope-finding drainage, and meanwhile, the deformation joint and the drainage ditch are combined into a structural form, the structural form is located in an area in a dotted line in fig. 3, roof concrete reinforcing layers 301 are arranged on two sides outside the dotted line, as shown in fig. 4, the top of the right side wall of the drainage ditch 302 inside the structure is lower than a roof plate 303 on the right side, a vertical deformation joint between main structures forms a horizontal gap 304, the gap is higher than the bottom of the drainage ditch 302 and lower than the roof plate 303, a drainage ditch cover plate 305 is arranged above the drainage ditch 302, and the drainage ditch cover plate 305 is the lowest point (area in the dotted line) of the roof in fig. 3, so that the smoothness of the roof is ensured, and the problem of roof drainage is solved.

However, this type of deformation joint structure still has the following disadvantages:

(1) the horizontal gap is positioned on the side wall of the drainage ditch and is too close to the drainage ditch cover plate, rain or roof falling water easily penetrates through the drainage ditch cover plate and splashes into the horizontal gap, and the waterproof sealing rod in the horizontal gap is splashed, so that the service life of the waterproof sealing rod is influenced;

(2) if the building is located in a rainy region in the south, continuous strong rainfall occurs frequently in summer, the drainage ditch is difficult to deal with large-discharge catchment of the roof, and in the continuous strong rainfall process, once the downpipe is blocked, the water level of the drainage ditch rises, the water pressure of the side wall is increased, the deformation joint waterproof sealing rod is soaked for a long time, and deformation joint backflow water seepage is easy to occur;

(3) the roof overflow mouth is higher than the setting of escape canal minimum, for preventing that ponding in the escape canal from spilling over, need set up the overflow mouth in the escape canal, and the overflow mouth must be less than horizontal movement joint and be higher than the setting at the bottom of the ditch slightly, must deepen the escape canal degree of depth, the daily maintenance clearance of being not convenient for.
