ActiveCN106592824AReduced duration extensionAvoid destructionWallsThin walledElectricity
The invention relates to the technical field of concrete shear walls, and discloses a precast cavity type middle-thin wall concrete shear wall. The middle-thin wall concrete shear wall comprises a wall body. A plurality of cavities penetrating in the height direction of the wall body are arranged at intervals in the length direction of the wall body. A connecting bar is arranged in each cavity, wherein the connecting bar comprises a plurality of connecting branch bars, one ends of the connecting branch bars are connected together, and the other ends of the connecting branch bars are circumferentially connected with the inner wall of the cavity to divide the cavity into a plurality of branch cavities, and each branch cavity is used for installing a pipeline. Longitudinal bars are arranged around the wall body in the height direction of the wall body. The outer hoop of each longitudinal bar is provided with a hooping. According to the middle-thin wall concrete shear wall, water and electricity pipeline installing is convenient, construction period prolonging caused by later period decorating is relived, meanwhile, the damage to the structure wall body caused by later period project installing is avoided, in addition, the using amount of materials is reduced, and the anti-seismic property of a component is improved.

Section steel concrete frame inbuilt steel plate core cylinder with doubly superimposed bottom and producing method thereof

The invention discloses a section steel concrete frame inbuilt steel plate core cylinder with a doubly superimposed bottom, which is composed of a section steel concrete superimposed frame column, a power-wasting soft steel plate and a steel plate concrete shear wall. The section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed bottom is a doubly superimposed column of a superimposition of an externally stuck energy-wasting soft steel plate and a steel tube concrete column as well as a superimposition of the steel tube concrete column and a reinforced concrete column; and the section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed bottom is a multi-combination body of a combination of reinforcing steel bars and concrete, a combination of the steel plates and concrete as well as a combination of the section steel concrete frame column and the steel plate shear wall. The section steel concrete frame inbuilt steel plate core cylinder with the doubly superimposed bottom, disclosed by the invention, has greater initial rigidity, higher bearing capability, slower attenuation of the bearing force and the rigidity as well as better integral quake-proof energy consumption performance than those of normal reinforced concrete cylinders and has relatively steady earthquake resistant capability in a later stage. After soft steel sleeves are additionally arranged, the soft steel sleeve at the outer side is firstly yielded to consume energy of an earthquake input structure and can play resistance power and ductility functions even when the soft steel sleeve at the outer side is damaged, so that previous damage and destruction of the high-intensity steel plate can be prevented and delayed.

Composite block equipped with metal net and/or reinforced bar plasterer, and its bonding construction method

The invention relates to a composite member provided with a metal gauze and / or a reinforced coating, which relates to a building composite member and aims to solve the problems of heavy weight of a concrete floor and so on. The composite member comprises a cement mortar layer, a core layer, and the metal gauze and / or reinforcing steel bars in the cement mortar layer, wherein, the cement mortar layer is arranged outside the core layer. The primary cementation is as follows: an interface agent is coated on the surface of the core layer, and the core layer is bonded with a cement mortar coating into a whole when the interface agent is wet. The secondary cementation is as follows: after the interface agent coated on the core layer for the first time is dried, the interface agent is coated on the core layer for the second time, and the core layer is bonded with the cement mortar coating into a whole when the interface agent coated for the second time is wet. The tertiary cementation is as follows: the interface agent is coated on mutual seams of the massive or platy core layers, and the core layers coated with the interface agent are bonded with each other for assembly; or the interface agent is coated on walls of holes passing through the core layers, and the cement mortar layer running through the core layers is bonded with the walls of the holes in the core layers through the wet interface agent. The composite member has the advantages of lightening of the weight of the building member, good heat-insulating property, low manufacturing cost and convenient construction.
