Description

Concrete dividing wall

Technical Field

The utility model relates to the technical field of building construction of buildings or large-scale equipment, in particular to a concrete dividing wall suitable for a cooling tower.

Background

In waste heat power generation engineering, a cooling tower is an important part of a cold end system of a power plant, and the cooling efficiency of the cooling tower influences the vacuum degree in a condenser, so that the circulating heat efficiency of the whole thermodynamic system is influenced. The forced ventilation cooling tower adopts a forced ventilation mode of a fan, so that a high and huge air duct required by the natural ventilation cooling tower is not required, the size of the forced ventilation cooling tower is greatly reduced, and the manufacturing cost is greatly reduced. In addition, the fan of the mechanical ventilation cooling tower can adjust the air quantity, so that the cooling tower works stably and is not affected by the climate. The draft generated by the fan is much larger than that generated by the natural ventilation tower, so that the cooling water can be stably close to the temperature of the wet air, and higher efficiency is achieved.

For the above reasons, in waste heat power plants of small units, mechanical ventilation cooling towers are widely used, and the structural form is generally a steel structure or a concrete structure. The cooling tower with the steel structure is convenient to install, light in structure, relatively high in manufacturing cost and also needs to be maintained regularly in the later period. The concrete cooling tower has low cost, low requirement for later maintenance, convenient use and often becomes the first choice under the condition of the permission of the general construction period.

On the other hand, the cooling tower is always in a water spraying environment, so that the partition walls (used for isolating the space and meeting the ventilation requirement) in the cooling tower and on the periphery are also of concrete structures, and brick masonry is not adopted. The main reason is that the durability and the sealing performance of the concrete dividing wall are good under the water spraying environment.

In the scheme of the prior art, the cooling tower with the concrete structure adopts a frame structure, and the whole concrete dividing wall inside the cooling tower is arranged according to the process requirement (the cooling tower cannot be adjusted in structural design), so that the rigidity of the main body structure is greatly adversely affected. The structural rigidity is irregular and the structural rigidity is overlarge, and the direct result is poor shock resistance. On the other hand, the structural member reinforcement scheme employed for enhancing the seismic performance is less economical. Eventually, the earthquake response of the actual structure is difficult to evaluate, and the requirements of the current earthquake-proof standard are difficult to meet.

Disclosure of Invention

In order to solve the problems, the utility model provides the concrete dividing wall which can effectively solve the problems of irregular structural rigidity and overlarge structural rigidity.

In order to achieve the above purpose, the concrete dividing wall comprises an external dividing wall body, two concrete columns at two sides, a concrete upper beam and a concrete lower beam, wherein the concrete lower beam supports the dividing wall body, and the side edges of the dividing wall body respectively form vertical joints and transverse joints with the concrete columns at two sides and the concrete upper beam. The structure is characterized in that the vertical joints and the horizontal joints formed by the separation wall body, the concrete columns and the concrete upper beams can reduce the rigidity of the whole structure and play a role of deformation joints, and the multiple vertical joints and the horizontal joints can separate the building into smaller parts to form relatively independent shockproof units, so that the phenomenon that the whole vibration of the building is uncoordinated when an earthquake occurs due to the overlarge rigidity of the whole structure is avoided, and the building is damaged.

The further scheme is that in order to increase the stability of the concrete dividing wall, stainless steel angle steel covering vertical joints and transverse joints is arranged between the dividing wall and concrete columns on two sides and between the dividing wall and a beam on the upper layer of concrete, and the stainless steel angle steel is arranged on the inner side and the outer side of the concrete dividing wall. The concrete partition wall has wind load acting on the surface, and as the partition wall has only one end supported, the stability of the partition wall can be affected when the wind load is too large, so that stainless steel angle steel is arranged on the inner side and the outer side for dispersing the wind load acting force of the surface of the partition wall, the partition wall can have a limiting effect, and the stability of the partition wall can be increased.

In order to increase the connection firmness of the stainless steel angle steel, stainless steel embedded parts are embedded in one side of the concrete columns on two sides and the concrete upper beam facing the separation wall body; one side of the stainless steel angle steel is welded on the stainless steel embedded part, and the other side of the stainless steel angle steel is clung to the separation wall body. Because only one end of the angle steel is welded and fixed, the angle steel is not fixed with the separation wall body, so that the separation wall body can realize vertical and horizontal deflection when an earthquake occurs, and the earthquake resistance is enhanced.

In order to reduce the influence caused by engineering errors, a foaming expansion material filling a gap is arranged between the separation wall body and the stainless steel angle steel. Because of the construction error, when the engineering error causes the uneven separation wall, the gap between the separation wall and the stainless steel angle steel can be filled with foaming expansion materials.

In order to increase the structural strength of the stainless steel angle steel, the stainless steel angle steel is provided with stiffening ribs, and one surface of the welding edge of the stainless steel angle steel is provided with plug welding holes. Because the stainless steel angle steel bears the effect of dispersing and separating wind load force on the surface of the wall body, the structural strength of the stainless steel angle steel can be greatly increased by arranging the stiffening ribs in the vertical direction of the stainless steel angle steel, and the arrangement of the plug welding holes can facilitate the welding operation of the angle steel and the embedded part, so that the welding area of the angle steel and the embedded part is increased to ensure that the angle steel is welded more firmly.

In order to increase the tightness, a water stop belt is arranged at the joint position of the separation wall body and the stainless steel angle steel, and the water stop belt is covered with a rubber elastomer. The water stop strip, the stainless steel angle steel and the separation wall body form a water stop joint together, so that the waterproof performance of the water stop joint is ensured.

In order to better fix the water stop and the rubber elastomer, the water stop and the rubber elastomer are respectively fixed on the stainless steel angle iron and the separation wall body through stainless steel expansion bolts. The water stop and the rubber elastic body are respectively fixed on the stainless steel angle steel and the separation wall body, so that the stability of the water stop and the rubber elastic body can be increased.

According to the concrete dividing wall designed by the utility model, the dividing wall body, the concrete columns at two sides and the concrete upper beam form a vertical seam and a transverse seam respectively, the building is divided into smaller parts to form relatively independent shockproof units, the problems of irregular structural rigidity and overlarge structural rigidity caused by the dividing wall are solved, the structure can be designed according to a normal frame structure, and the structural member reinforcement scheme has higher economical efficiency. The partition wall has the advantages that the earthquake resistance of the structure is greatly improved, the structural rigidity is reduced, the earthquake effect is weakened, the consumption of reinforcing steel bars of the whole structure is reduced, and the safety is greatly improved.
