Building exterior wall structure

Abstract

The invention discloses a building exterior wall structure. The building exterior wall structure comprises one or more keel brackets which are embedded in a building exterior wall, wherein sides, opposite to a building exterior wall, of the keel brackets are bugled with concession boxes; concession cavities are arranged in the middle of the concession boxes; the concession boxes are embedded intoconcave cavities in the building exterior wall; a circulating channel is arranged on the middle of the keel bracket; one side, which is opposite to the circulating channel, of each concession cavity is provided with an opening; one side, which is away from each concession box, of each keel bracket is equipped with a fixed shaft sleeve; a movable rod is inserted into each fixed shaft sleeve; and the keel brackets are horizontally arranged in the building exterior wall. When being used in summer, the building exterior wall can absorb heat of a building body very well, absorbs heat of a curtain wall, reduces the temperature of the curtain wall and the building body, reduces the indoor temperature, guarantees cooling, can conveniently regulate extending-out length of each curtain wall board, and solves the mounting problem of external equipment.

Description

technical field [0001] The invention relates to the construction field, in particular to a building exterior wall structure. Background technique [0002] On the exterior wall of the existing building, in order to increase the aesthetics of the exterior, we will lay a layer of curtain wall panels on the exterior wall of the building. The curtain wall panels contact each other to form a closed curtain wall surface. The curtain wall surface will absorb in summer. A lot of heat causes the temperature of the entire building to rise. If the curtain wall panels can maintain a relatively comfortable temperature, then the temperature of the internal building exterior walls will not be very high, making the internal temperature of the building more comfortable; [0003] Furthermore, we often see a lot of external installation equipment on the outside of the building, such as the most common air conditioner external unit, the air conditioner external unit is generally equipped with an...

Problems solved by technology

[0003] Furthermore, we often see a lot of external installation equipment on the outside of the building, such as the most common air conditioner external unit, the air conditioner external unit is generally equipped with an external unit bracket, and the external unit bracket is screwed into the building wall Among them, the screws pass through the curtain wall panels to cause damage to the curtain wall panels, and this method is very unsightly. It is difficult to disassemble the external unit bracket after it is fixed and installed by screws. The disassembly and installation require aerial work and installation. This process is very important for installation. It is very dangerous for personnel. If external equipment wants to be installed on the wall, only external brackets can be used, which increases the installation limitations of external equipment, and external equipment is installed on the external wall only by external brackets. The installation strength is not enough, and there is no other protective structure for the external equipment, so it is very dangerous to use
