Description

Roof structure

Technical Field

The utility model relates to a building structure field, concretely relates to roofing structure.

Background

The parapet wall is a low wall around the roof of a building, and has the main functions of maintaining safety, and applying waterproof pressed bricks at the bottom to prevent water seepage of a waterproof layer or overflow of roof rainwater.

According to the national building code, the height of the parapet wall of the upper roof is generally between 1.2 and 1.5 meters.

The parapet wall on the roof of the person is used for protecting the safety of the person and has a decorative effect on the building elevation; the parapet wall without roof has the facade decoration function and also belongs to a waterproof structure.

The problem of roof leakage at the present stage is more and more the focus of social and industry concerns, one of the parts with the most serious roof leakage is the parapet part, and because the part has a complex structural form and a high construction difficulty, the parapet part always becomes a serious disaster area of roof leakage.

However, in the past, in addition to the main reason that the waterproof performance is not standardized, the unreasonable structure design of the parapet part is also a major cause of leakage, and the leakage of the parapet part of the roof facing the old community is more and more serious.

The construction step of the parapet part at the present stage is that the reverse bank at the lower part of the parapet and the roof structural slab are cast in situ together, the material is a concrete structure, and the upper part of the parapet is generally built with brick walls or building blocks. Just because the two materials are different, some problems can occur at the parapet part, such as:

1) referring to fig. 1, a crack channel is formed between the blockwork 202 and the roof structure panel 1 (or the concrete inverted beam) due to shrinkage deformation, rainwater flows from the crack of the blockwork and the roof structure panel along the crack channel, bypasses the waterproof layer 3, seeps into the upper part of the roof structure panel, and water leakage is caused when structural cracks occur.

2) Referring to fig. 2, when the building is used for a long time, the outer wall leveling layer 11 is prone to cracking or building block mortar of the building block wall 202 is not full and not appropriate in pointing in the previous construction process, and rainwater is prone to seeping into a room from the outer wall edge along the inner gap of the parapet building block wall.

The above-mentioned outer wall seepage problem all has a common characteristic, and the waterproof layer of roofing construction has no way to this kind of infiltration, because the rainwater is directly infiltrated to the waterproof layer below through parapet wall body, meets the crack of roofing structure board again, causes the roofing seepage.

This leakage problem arises primarily because existing waterproofing systems do not form a closure in the parapet facade, resulting in a water leak.

Accordingly, there is a need for a roofing structure having good structural integrity and effective leakage reduction.
