Description

A waterproof structure of expansion joint ridge cover plate

technical field

The utility model belongs to the field of building roof waterproof construction methods, and in particular relates to a waterproof construction of an expansion joint ridge cover plate, that is, a waterproof construction measure at the roof expansion joint, and can adapt to the expansion and contraction of the roof affected by temperature at the expansion joint.

Background technique

At present, most of the enclosure methods of profiled metal roof panels between the expansion joints of domestic building structures are to lay roof profiled steel plates between the structural units on both sides of the expansion joints, and then press the roof panels on both sides with a retractable cover plate. Cover the profiled steel plate, and finally use the connector to connect the roof profiled steel plate and the retractable cover plate into a whole. Although this method can adapt to the shrinkage and expansion of the structure caused by temperature changes, the processing of the retractable cover is complicated, and the amount of expansion is limited, and it is easy to cause water seepage and rain leakage on the roof at the position of the expansion joint. Especially in the coastal areas where typhoons are often ravaged and the structures with long plant lengths, water seepage and rain leakage of the roof profiled steel plates at the expansion joints often occur.

Utility model content

The purpose of this utility model is to provide a waterproof structure of expansion joint ridge cover plate, which can fundamentally solve the problem of roof panels at expansion joints in coastal areas with many typhoons and rainstorms and in structures with large length of factory buildings due to strong wind and heavy rain environment. Problems such as water seepage and rain leakage, meet the requirements of applicability and durability.

In order to achieve the above object, the technical scheme of the utility model is:

A waterproof structure for expansion joint roof ridge covers, which includes: fixed brackets, laid on both sides of the seam width at the ridge expansion joints of a profiled metal roof panel; roof ridge covers, laid along the length of both sides of the expansion joints, There is a mutual overlapping length at each place, and they are bonded to each other with structural glue; and the middle part of the ridge cover plate is located at the expansion joint, and a corrugated structure is provided; the waterproof liner is arranged above the expansion joint under the ridge cover plate, The waterproof liner is a T-shaped structure, the middle of which is a corrugated structure that matches the corrugated structure of the roof ridge cover, and the width of one end of the waterproof liner is the same as the width of the roof ridge cover, and the end is connected to the ridge through the fixing bolt assembly. The cover plate is fixed on the fixed bracket, and the width of the other end of the waterproof lining plate is smaller than the distance between the fixing bolt assemblies on both sides, so that the waterproof lining plate at this end forms a movable structure between the two fixing bolt assemblies on the other side of the expansion joint.

Preferably, the ridge cover plate is a stainless steel plate, an aluminum plate or a color steel plate.

Preferably, the waterproof liner is a stainless steel plate, an aluminum plate or a color steel plate.

Preferably, the structural glue is a high-performance silicone structural glue or a neutral transparent silicone structural glue.

Preferably, the fixing bolt assembly includes connecting bolts, rubber washers and washers.

At the location of the expansion joint of the roof ridge of the building structure, when the rainwater flows along the horizontal slope, the rainwater flows through the roof ridge cover plate to the profiled metal roof panels on both sides and flows down the slope; when the rainwater flows along the longitudinal direction of the roof ridge, the rainwater flows through the expansion joint The overlapping gap of the ridge cover plates on both sides flows to the waterproof liner, and then flows along the slope through the waterproof liner to the pressed metal roof panel and flows down the slope. When the temperature rises or falls, the structure expands and contracts, and the width and spacing of the structural joints become smaller or larger. The glue used for the structure at the overlapping joints of the ridge cover can adapt to expansion and contraction and can be partially waterproof. One side of the waterproof liner is fixed with fixed bolts, and the other side is movable to accommodate the change of the gap width, and at the same time ensure that part of the infiltrated rainwater is diverted to the profiled metal roof panel.

Compared with the prior art, the utility model has the following advantages:

1. The expansion and contraction of this structure can fully adapt to the width change of the roof expansion joint under the temperature change, and prevent the local damage of the roof panel.

2. The ability to prevent rain is greatly enhanced, reducing the phenomenon of rain leakage at expansion joints.

3. Simple structure and convenient construction.
