1、 What is the quota of roof manhole cover?

The ceiling manhole is included in the ceiling. There is no manhole sub item in the general quota, but now the manhole cost is getting higher and higher.

Quota is a standard that specifies in advance the amount of resources consumed to complete a unit of qualified products under the conditions of reasonable labor organization and rational use of materials and machinery. It reflects the level of social productivity in a certain period. For each construction project, the labor volume is calculated, including basic labor and other labor. Plus the materials of this project, including basic materials and other materials. The unit price of labor is stipulated locally according to the labor value of different types of work at that time, and the value of materials is the budget price formulated according to the market price in the early stage.

2、 How to do the roof manhole?

Concealed method and direct method can be used to make roof vent:

1. Concealment method: the normal construction method is adopted for waterproof treatment at the interface, and the part to the room is designed into the ventilation pipe.

2. Direct method: that is, the air vent is made directly from the roof for normal construction and waterproof. The difference between the two methods is that they are the same after leaving the roof. The difference is in the house, one in the light and one in the dark.

3、 What are the materials for making roof manhole?

1. Gypsum double aluminum edge inspection and repair

Gypsum double aluminum edge inspection and repair opening (hole) is a product made of high-strength gypsum, glass reinforced fiber and aluminum alloy by reverse die extrusion. Its raw materials have high strength and high environmental protection, and it is the first choice in the international decoration industry. In recent years, it has also been widely recognized in the domestic decoration industry!

2. Aluminum alloy manhole

(1) Good quality: it is made of aluminum alloy, with light weight, strong bearing capacity, no rust and no deformation.

(2) Arbitrariness: any size can be customized without high mold cost and quantity limit (such as triangle and polygon).

(3) Mildew resistance: in the high temperature environment, the dense material of the manhole makes it difficult for mold to breed, and the trouble caused by mold breeding of porous sound-absorbing materials is relieved.

(4) Easy to install: easy to install and fix. It only takes 1-2 minutes to install one.

(5) High cleanliness: it can effectively avoid micro dust falling. It is an ideal choice for places with cleaning requirements.

3. Aluminum alloy composite manhole

The aluminum alloy composite manhole is processed by special aluminum profile, oxidation and special process. Its beauty is the same as that of gypsum double aluminum frontier inspection manhole. The difference is that it has higher closure, and the gap is only 1mm. It can be customized in any size. It is made of all aluminum alloy, with better quality!

4. Aluminum alloy composite lower flap manhole

The aluminum alloy composite lower flap manhole is made of the same material as the aluminum alloy composite manhole. The difference is that the profile is more special and special accessories, which are made through complex processing!

5. Wall manhole

The wall manhole is made of aluminum alloy profile, galvanized plate, stainless steel lock and connector. The manhole color is divided into two types: matte and bright, and a new generation of wall manhole.
