Description
Technical field
The utility model is related to a kind of construction, the strengthening reconstruction structure of particularly a kind of existing building.
Background technology
With the continuous progress of science and technology, social civilization is continued to develop, and it is large quantities of that country's reform and opening-up early stage is built
City exist aging disadvantage highlighted, auxiliary facility imperfection, impersonality, high energy consumption, potential safety hazard etc. not only into
For livelihood issues, the stumbling-block of restriction urban development is also become.
At present, the balcony fence of old cell is generally that precast concrete is spliced to form, part balcony fence concrete strength
Relatively low, exterior plaster, which is wiped one's face, to be pasted not strongly, has the phenomenons such as hollowing, crack, cause rainwater to pour into, steel bar corrosion, breast board concrete pine
Dissipate and come off, in order to ensure the safety of resident, eliminate safe hidden trouble, it is necessary to carry out strengthening reconstruction to existing balcony, but balcony adds
Gu facing some problems in work progress, such as working time is limited by the time of having a rest of resident, sooner or later can not be by capital construction commission of city
Defined time construction, it is impossible to organize night to apply, construction production efficiency reduction, can have an impact to project progress.
Utility model content
The purpose of this utility model is to provide a kind of both balconied strengthening reconstruction structure, on existing balcony structure basis
Upper, progress strengthening reconstruction, solves the problem of existing balcony structure is long neglected and in disrepair.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of both balconied strengthening reconstruction structure, is connected between balcony slab and exterior wall, including balcony reinforce skeleton and
Balcony reinforces breast board；The balcony reinforce breast board upper end be connected by connecting top frame with balcony reinforcing skeleton, lower end pass through it is spacing
Underframe is reinforced skeleton with balcony and is connected；The balcony is reinforced skeleton and is distributed along balcony slab outward flange, and balcony reinforces the two of skeleton
End is connected with exterior wall.
Strengthening reconstruction structure also includes the embedded board for being embedded in the anti-platform upper surface of balcony slab；The embedded board is along anti-platform
It is elongated to set, it is vertically connected with embedded ribs between balcony slab horizontal bar；Correspondence is provided with through balcony slab and erects muscle on the embedded board
With the perforation of embedded ribs, and embedded board erects muscle and embedded ribs with balcony slab respectively and is welded and fixed.
The balcony is reinforced skeleton and is connected on the anti-platform of balcony slab, including parallel to anti-platform, the horizontally disposed steel that bears down on one
Manage and be vertically connected on the column beared down on one between steel pipe and anti-platform.
The end of the steel pipe that bears down on one is welded with connecting plate and is connected by fastener with exterior wall.
The bottom of the column is welded with column bottom plate and is connected by column bottom plate with embedded board；The column bottom plate
Upper correspondence is provided with the perforation that muscle and embedded ribs are erected through balcony slab, and column bottom plate erects muscle with balcony slab respectively and embedded ribs are welded
It is fixed.
The cross section of the connection top frame is L-shaped, and one limb, which is fixed on balcony, to be reinforced skeleton and bear down on one on steel pipe, another limb
