Technical Field

The invention relates to the technical field of electromechanical installation engineering, in particular to a wall-through anti-leakage device for a roof air duct.

Background

The construction and installation technical scheme of the existing roof air pipe is as follows:

designing the model specification according to a construction drawing, and prefabricating and processing the air duct;

transporting the air pipe to a roof for installation;

the position of the air duct is filled with materials and cement mortar which are not used.

The technical defects of the prior art are as follows:

1. the wall body position of the air pipe air penetrating well is filled with cement pump slurry, and the phenomenon of filling is not full.

2. Because the air pipe is made of a thin iron sheet material, and the filling material is a hard material, the filling position of cement mortar can be cracked after the air pipe is used for a period of time.

3. The tuber pipe is horizontal installation, and when raining, the rainwater can flow to the tuber pipe well in following the gap of packing not full or packing fracture department to on the gap position that the tuber pipe wore the air shaft wall body from the plane on the tuber pipe or direct scouring, the rainwater to flow to indoor along the well, cause interior decoration or equipment to steep the water and damage.

4. If the through-wall position is cracked, the through-wall position needs to be repaired after being knocked out. However, the crack phenomenon at the gap can be caused after the repair is carried out for a certain time, and the fundamental problem can not be solved. Therefore, the maintenance is repeated, the cost is high, and the reputation influence is not good.

Disclosure of Invention

In order to solve the defects of the prior art, the invention provides a wall-through anti-leakage device for a roof air duct.

The technical scheme provided by the invention is as follows: a roof air duct wall-through anti-leakage device comprises a reinforced concrete and air shaft building wall body with flashing and waterproof layers, wherein an air duct is vertically arranged in the reinforced concrete air shaft building wall body, and a horizontal fan joint is arranged on the air duct; building a ventilating shaft building wall body at the top of the reinforced concrete ventilating shaft building; the fan horizontally penetrates through the air shaft building wall, and a masonry plug is arranged between the lower side surface of the air pipe joint and the air shaft building; and a flexible structure plugging glue is also arranged between the water air pipe and the air shaft masonry body.

When the air pipe is prefabricated, the inner side of the wall body of the horizontal air pipe through air well is heightened by 50mm to form an outward slope. After the air pipe is installed, original cement mortar is filled in a gap between the air pipe and the position of the ventilation shaft masonry wall, and the gap is changed into an external flexible structure sealing glue filling and sealing mode. The air pipe penetrates through the masonry wall body, and the water batching plates which are 100mm wider than the two sides of the air pipe are arranged on the upper portion of the air pipe, so that rainwater is prevented from directly washing gaps between the air pipe and an air shaft wall body.

As shown in the attached figure 1, the mounting structure can be processed by adopting a conventional construction process, and for the air duct structure provided by the invention, the height of the inner side of the wall body of the air duct penetrating well is increased by 50mm to form an outward slope, so that rainwater cannot flow into the air duct along the air duct when the upper plane of the air duct has rainwater; the air pipe air-through well position is rigidly filled with raw cement mortar, the structural adhesive is optimized to be flexibly filled fully, and the filling position of the deformed air pipe is prevented from cracking; the air pipe penetrates through the masonry wall body, and the water batching plates which are 100mm wider than the two sides of the air pipe are arranged on the upper portion of the air pipe, so that rainwater is prevented from directly washing gaps between the air pipe and an air shaft wall body. Through the process, rainwater is guaranteed not to flow into the wind well, the required technical effect is achieved, and the effect is once and for all.

Furthermore, the top of the air shaft masonry is matched with an air shaft cover plate. The air shaft cover plate is of a concrete pouring forming structure, and can be placed at the top of the air shaft masonry, and the air shaft cover plate extends out of the air shaft.

Furthermore, the air pipe penetrates out of the periphery of the wall body of the air shaft and is reserved with uniform gaps, the inner side of the air pipe is filled with flexible fire-insulating materials, the outer part of the air pipe is filled with structural glue flexibly, and the phenomenon that the filling position of the air pipe is cracked after deformation is prevented.

Furthermore, the horizontal air pipe at the wall penetrating position of the air pipe is high inside and low outside and inclines towards the outside of the air well, so that rainwater on the surface of the air pipe cannot flow into the air well along the upper plane of the air pipe.

Furthermore, the air pipe penetrates through the masonry wall body, and the water-spraying plates which are 100mm wider than the air pipe are arranged on the upper portion of the air pipe respectively, so that rainwater is prevented from directly washing gaps between the air pipe and the air shaft wall body.

Furthermore, a connecting flange is arranged on the fan joint on the outer side of the flexible structure plugging glue, the upper side face of the fan joint between the flexible structure plugging glue and the connecting flange is formed into a slope structure, and the galvanized iron sheet flashing plate covers the connecting flange. And filling the filling layer and the coating layer after the fan joint is installed. As shown in the attached drawing 1, the galvanized iron sheet flashing covers the connecting flange to prevent rainwater from flowing into the slope on the left side, and the fan joint of the slope structure on the left side of the connecting flange further prevents the rainwater from flowing back to the air inlet shaft.

The beneficial technical effects of the invention are as follows:

1. because the horizontal air pipe penetrates through the wall of the air shaft and is high inside and low outside, a slope is formed, and when rainwater exists on the upper plane of the air pipe, the rainwater cannot flow into the air shaft along the air pipe.

2. The air pipe penetrates through the air shaft and is rigidly filled with raw cement mortar, the filling is optimized to be structural adhesive flexible filling, the filling position after the air pipe deforms is prevented from cracking, and the effect of once and for all is achieved. The position is clogged to the tuber pipe does not ftracture, and the rainwater just can't flow in the tuber pipe well.

3. Because the water batching plate is arranged at the wall penetrating position of the air pipe, rainwater cannot directly wash the joint of the air pipe penetrating shaft, and rainwater can flow into the air pipe shaft to be guaranteed multiply.

4. The flashing, the gradual change short circuit of tuber pipe, structure glue cost are very little, simple to operate, but the effect is showing.
