Abstract

The utility model relates to an outer wall prefabricated slab in a framework structure, comprising a square frame framework which is formed by fixedly connecting reinforcing steel bars at the external side and another square frame framework which is as large as the square frame framework and is formed by connecting reinforcing steel bars at the internal side. The two square frame frameworks are vertically and fixedly connected through broken bridge reinforcing steel bar connecting members; the reinforcing steel bars at the internal side and the external side are fixedly and obliquely connected to form a framework; a layer of reinforcing steel bar mesh is paved on the two square frame frameworks; a steel wire gauze cement layer and a steel wire gauze concrete layer are respectively manufactured on the reinforcing steel bar meshes at the internal side and the external side; and a foam concrete thermal insulation material is filled between the steel wire gauze cement layer and the steel wire gauze concrete layer. The outer wall prefabricated slab in the framework structure, disclosed by the utility model, can finish all the procedures of an external maintenance structure of a building for once when mounted at the outside of a building body so that on-site operation and generation of construction waste is greatly reduced. The outer wall prefabricated slab in the framework structure, disclosed by the utility model, is particularly adaptable for installation of outer walls of large-scale buildings and high-rise buildings, is anti-seismic and energy-saving and has good thermal insulation performance.

Description

Frame structures exterior wall precast plate

Technical field

The utility model relates to a kind of frame structures exterior wall precast plate, has heat-insulating property, belongs to the prefabricated member in the construction work.

Background technology

Assembling exterior wall precast plate mainly by the exterior configuration of band mo(u)lding face, construct three parts with middle thermal insulation and form by the inboard structure of band interior decoration layer.At present this type precast plate is because the middle general material of heat insulating material is soft, usually the sheet material of the structure usefulness in the interior outside processed various tongue and grooves and is convenient to connect, though can solve the strength problem of whole wallboard like this; But the junction forms heat bridge easily; Can not satisfy the energy-conservation requirement of current building, and the intensity of sheet material is limited, particularly this type sheet material is difficult to cover than large space; Can not accomplish the outside of building separately and safeguard, and need add structure construction in addition.

The utility model content

The technical problem that the utility model will solve provides a kind of simple in structure, good heat insulating, and intensity is high, and the firm frame structures exterior wall precast plate of simple installation.

The utility model frame structures exterior wall precast plate; Comprising by the mutually orthogonal square frame skeleton that is fixedly connected into of outside reinforcing bar; By mutually orthogonal another square frame skeleton that is fixedly connected into identical size of inboard reinforcing bar; Connect through bridge cut-off rebar connector vertical fixing between the two square frame skeletons, inboard reinforcing bar and outside reinforcing bar pass through the oblique fixed connection of web member apart; Also lay fixedly one deck fine steel rib net on the square frame skeleton that outside reinforcing bar constitutes at least, smear cement mortar on the net at fine steel rib and process the ferrocement layer; Also lay fixedly one deck steel mesh reinforcement on the square frame skeleton that inboard reinforcing bar constitutes, build layer of concrete on it, filled and process concrete thermal-insulating material between ferrocement layer and layer of concrete.

The utility model frame structures exterior wall precast plate, wherein in the ferrocement layer outside with anti-play bonding applique surface plate.

The utility model frame structures exterior wall precast plate, make-up room interior trim layer wherein in the layer of concrete outside, the interior decoration layer is bonding gypsum plank or does to decorate and whitewash.

The utility model frame structures exterior wall precast plate wherein is embedded with the built-in fitting that installs and fixes usefulness in layer of concrete.

The utility model frame structures exterior wall precast plate is installed to outside the building main body, can be disposable all process steps of completion building outside enclosed structure, greatly reduced field operation and produced building waste.Among the square frame skeleton, fill up the foam concrete fire-retardant heat-insulation material; During installation, with monoblock precast plate hoisted in position, the built-in connection through different structure in the layer of concrete of inboard is fixedly connected with agent structure; It adapts to the skin installation application of different subjects structure; The special installation that adapts to heavy construction, external wall of high-rise building has good heat-insulating property, realizes the earthquake-proof energy-saving effect.

Fig. 2 is a frame structures schematic perspective view in the utility model frame structures exterior wall precast plate.

The specific embodiment

Visible by Fig. 1, Fig. 2; The utility model frame structures exterior wall precast plate comprises by the outside reinforcing bar 6 mutually orthogonal square frame skeletons that fixedly are welded into; By inboard reinforcing bar 7 mutually orthogonal another square frame skeletons that fixedly are welded into identical size, connect through bridge cut-off rebar connector 8 vertical fixing between two square frame skeletons, inboard reinforcing bar 6 and outside reinforcing bar 7 pass through web member 9 apart; Promptly select the oblique fixedly welding of thinner reinforcing bar for use, form stable stressed framework in the exterior wall precast plate; Also lay fixedly one deck fine steel rib net 10 of welding on the square frame skeleton that outside reinforcing bar 6 constitutes at least, smear cement mortar and promptly process ferrocement layer 1; The available anti-play bonding applique surface plate 2 in ferrocement layer 1 outside.Also lay fixedly one deck steel mesh reinforcement 11 of welding on the square frame skeleton that inboard reinforcing bar 6 constitutes; Build layer of concrete 4 on it, promptly process the concrete slab that comprises inboard reinforcing bar 6 and steel mesh reinforcement 11, in layer of concrete 4, bury the built-in fitting of multiple structure underground; Like steel plate, bolt and nut etc.; So that be fixedly connected or lift transportation,, whitewash like bonding gypsum plank or work decoration simultaneously at layer of concrete 4 outside make-up room interior trim layers 5 with the building main body.Filled and process concrete thermal-insulating material 3 between ferrocement layer 1 and layer of concrete 4, it has fire prevention, advantage such as durable and indeformable, aging.
