Description

Insulated roof exhaust pipe

Technical field:

The utility model relates to a section material for building, in particular to a thermal insulation roof exhaust pipe.

Background technique:

Building roofs are mostly designed for thermal insulation. The roof insulation layer uses cement expanded perlite. This insulation material is poured on site. Contains a lot of water when pouring. The normal construction process is to dry for a few days to reach a certain moisture content before constructing the upper leveling layer and waterproof layer. However, the current construction period requirements for construction projects are extremely unreasonable. In order to avoid a large amount of technical measures for the construction of concrete structures in winter, most buildings arrange the topping of concrete structures before the arrival of winter. With this arrangement, the roofing project will be carried out in winter. In winter, when the cement expanded perlite insulation layer is constructed, the drying time is much longer than that in summer due to the lower temperature. Considering the impact of rain and snow in winter, it is necessary to construct the upper screed and waterproof layer in time. Similarly, when the construction period is particularly tight and the interval between processes needs to be shortened as much as possible, it is also objectively required to carry out the next process, that is, the construction of the waterproof layer in a timely manner. In this case, if exhaust measures are not taken, the temperature will rise in the future, and the water in the cement expanded perlite insulation layer will evaporate and accumulate to form a large pressure, which will easily cause the upper leveling layer and waterproof layer to crack and leak. The recommended method in the Building Atlas is to set up exhaust grooves at a certain distance in both directions when constructing the insulation layer, and fill the grooves with light loose materials such as ceramsite. According to a certain range of roof area, an inverted U-shaped PP-R air outlet pipe protruding from the roof is provided at the interface of the two-way exhaust groove. There are three disadvantages of this approach: First, this kind of filling material is often used in a small amount, especially for buildings with small roof areas. The entire project will not use much, and a series of economic and quality control procedures such as procurement and acceptance must be carried out. Increase the workload; two, since the filling material is loose material, it is filled after the vent groove is formed, so when constructing the cement expanded perlite insulation layer to leave the vent groove, it is necessary to set up a special formwork, which increases the construction process; three, The T-shaped PP-R outlet pipe protruding from the roof is directly inserted into the loose exhaust material, which is not easy to fix firmly, and the exhaust effect is not good. After the roof is formed, the exhaust pipes are not arranged neatly and are not beautiful.

Utility model content:

The purpose of the invention of the utility model is to overcome the defects and deficiencies in the prior art and provide a thermal insulation roof exhaust pipe which is convenient for construction and has a good exhaust effect.

The utility model adopts the following technical solutions:

A thermal insulation roof exhaust pipe includes an exhaust pipe body placed between a concrete roof panel and an insulation layer, and an exhaust hole is arranged on the exhaust pipe body.

Compared with the prior art, the utility model adopting the above-mentioned technical scheme, the exhaust pipe is placed in the pre-buried separation joint of the concrete roof slab, the construction is convenient, the exhaust system is simple and beautiful, and the exhaust effect is good.

As a preferred solution of the present invention, the bodies of the two adjacent exhaust pipes are connected by a three-way joint, and the other port of the three-way joint is connected with the air outlet pipe protruding from the roof.

As a preferred solution of the present invention, the exhaust holes are evenly distributed.

As a preferred solution of the present invention, the three-way joint is replaced by a four-way joint.

Detailed ways:

Describe the utility model in detail below in conjunction with accompanying drawing and embodiment:

A thermal insulation roof exhaust pipe, see accompanying drawings 1 to 3, in the figure: exhaust pipe body 1, exhaust hole 2, tee joint 3, air outlet pipe 4, concrete roof panel 5, cement expanded perlite insulation Layer 6, cement mortar insulation layer 7, roof flexible waterproof house 8.

In this embodiment, the exhaust pipe body 1 is provided with an exhaust hole 2, and the two adjacently laid exhaust pipe bodies 1 are connected by a three-way joint 3, and the other port of the three-way joint 3 is connected to the port protruding from the roof. Outlet pipe 4 is connected. The air outlet pipe 4 extends through the cement expanded perlite insulation layer 6, the cement mortar insulation layer 7 and the roof flexible waterproof house 8 in sequence, and the exhaust holes 2 are evenly distributed on the exhaust pipe body 1. It can be set to 3-5cm according to actual needs.

When constructing the cement expanded perlite insulation layer 6, the PP-R exhaust pipe body 1 is laid bidirectionally according to a certain interval. The adjacent exhaust pipe bodies 1 are connected to the PP-R outlet pipe 4 protruding from the roof through a three-way joint 3 . When the temperature rises, the water in the cement expanded perlite insulation layer 6 evaporates and accumulates in the PP-R exhaust pipe body 1, and is discharged through the T-shaped PP-R air outlet pipe 4 protruding from the roof, thereby reducing the air pressure of the lower part of the flexible waterproof layer. Pressure, to avoid the cement mortar leveling layer and the flexible waterproof layer being cracked by water vapor and leaking accidents.

The three-way joint 3 in this embodiment can be replaced by a four-way joint.

The exhaust pipe body 1 in this embodiment can be made from local materials, which is convenient for construction and has a good exhaust effect, which can solve the problems of troublesome exhaust measures in the prior art, cumbersome procedures, poor exhaust effect, and unsightly roof after forming. technical problem.
