Description

Roof inner gutter structure

Technical Field

The utility model relates to a gutter technical field in the building, especially a gutter structure in roofing.

Background

The gutter, the long both sides of edge ditch on the roofing collect the catch basin that the rainwater is used for guiding roofing rainwater runoff. The gutter is an inner gutter and an outer gutter, and the inner gutter is the gutter inside the outer wall. At present, a square inner gutter is mostly adopted in an inner gutter in a steel structure project, and is easy to generate water accumulation due to stress deformation, so that the leakage problem is caused; meanwhile, the steel inner gutter is cold in winter, and the indoor and outdoor temperature difference is large. The so-called cold bridge problem easily appears in interior gutter, and traditional heat preservation method is at gutter outside parcel heat preservation cotton, and reuse wire net wraps the heat preservation cotton, but the heat preservation cotton falls out easily on the one hand like this, and the heat preservation effect is not good, also brings the problem that the construction is inconvenient, and the maintenance cost increases.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a gutter structure in roofing, the purpose is warp and produce ponding in order to solve the atress, and then the seepage appears, and colleagues produce the problem of cold bridge winter easily.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

the utility model provides a gutter structure in roofing, includes inner gutter skin, inner gutter inlayer to and including the packing layer between outer and the inner gutter inlayer of gutter, inner gutter inlayer cross-section is the U-shaped form, inner gutter outer cross-section is square, the packing layer has set gradually waterproof layer, heat preservation from inside to outside, is provided with the terminal surface step including the one end of gutter, and its other end is provided with the terminal surface boss with terminal surface step looks overlap joint adaptation.

Preferably, the inner gutter outer layer and the inner gutter inner layer are made of galvanized iron sheets. Thus, the function of preventing rain corrosion can be achieved.

Preferably, the heat insulation layer is made of rigid polyurethane foam. The heat-insulating layer made of the material has a closed-cell structure, good heat-insulating effect, light weight and convenient construction, so that the weight of the inner gutter can not be increased, and the heat-insulating layer can play a role in heat insulation and the like.

Preferably, the end surface step has a depth of 10cm and a height of 5 cm. Therefore, the area of the lap joint part with the end surface boss is not large, and the effects of leakage prevention and heat preservation cannot be influenced.

The utility model has the advantages that:

the utility model provides a roof inner gutter structure, the inner filling layer of which is connected to increase the thickness of the inner gutter, the inner layer of the inner gutter is not easy to deform, the waterproof layer in the filling layer can prevent rainwater leakage, the later-stage water leakage maintenance frequency is reduced, and the later-stage maintenance cost is also reduced; meanwhile, the heat-insulating layer in the filling layer strengthens the heat stability and the water resistance of the inner gutter; the end surface boss and the end surface step are lapped and bonded by the sealant, so that the construction process is simplified, and the construction efficiency is improved.

Detailed Description

In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.

Examples

As shown in fig. 1, a roof inner gutter structure comprises an inner gutter outer layer 2, an inner gutter inner layer 3 and a packing layer between the inner gutter outer layer and the inner gutter inner layer, wherein the section of the inner gutter inner layer is U-shaped, the section of the inner gutter outer layer is square, the packing layer is sequentially provided with a waterproof layer and a heat insulation layer from inside to outside, one end of the inner gutter is provided with an end surface step, and the other end of the inner gutter is provided with an end surface boss in lap joint with the end surface step.

In use, as shown in figure 2, the inner gutter is mounted between two building columns on a support, one inner gutter is overlapped with the end surface step of the adjacent inner gutter by the end surface boss, and a sealing adhesive is applied to the overlapped part before overlapping. The rainwater flows into the inner gutter along the inclined building roof, and because the section of the inner layer of the inner gutter is in a U shape, the rainwater can smoothly flow to the bottom along the surface of the inner layer of the inner gutter, and a certain height difference exists when a plurality of supports are installed, so that the rainwater in the inner gutter can be discharged. The packing layer of the inner gutter relatively increases the thickness of the inner gutter and strengthens the integral rigidity of the inner gutter, so that the inner gutter is stressed and is not easy to deform, and the waterproof layer arranged in the packing layer can still ensure that the inner gutter is watertight and smoothly drains rainwater even if the inner layer of the inner gutter fails due to corrosion, breakage and the like; the heat-insulating layer arranged in the heat-insulating layer can ensure that the heat-insulating layer can work normally in winter.

Furthermore, the outer layer of the inner gutter and the inner layer of the inner gutter are both made of galvanized iron sheet. Thus, the function of preventing rain corrosion can be achieved.

Furthermore, the heat-insulating layer is made of rigid polyurethane foam. The heat-insulating layer made of the material has a closed-cell structure, good heat-insulating effect, light weight and convenient construction, so that the weight of the inner gutter can not be increased, and the heat-insulating layer can play a role in heat insulation and the like.

Furthermore, the depth of the end surface step is 10cm, and the height of the end surface step is 5 cm. Therefore, the area of the lap joint part with the end surface boss is not large, and the effects of leakage prevention and heat preservation cannot be influenced.

Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
