Description

Punch ruggedized construction after a kind of shear wall large area
Technical field
The utility model belongs to strengthening reconstruction field, and in particular to punch ruggedized construction after a kind of shear wall large area.
Background technology
The second stage that the construction in current China is combined in new zone development with reconstruction of the old city town, and forward direction is with extending old building Third developing stage based on reinforcing strides forward.
According to the statistics made by the departments concerned, 50% enters the ageing step in the building of more than existing 50 hundred million square metres of China cities and towns, Wherein there are about 10~2,000,000,000 square metres of palpus strengthening reconstructions to use, this brings fabulous development machine to building strengthening reconstruction industry Meeting, and theoretical research to Appraisal of Building, reinforcing and renovation technique and oneself is promoted and applied into the task of top priority.
Wall of the shear wall as the main horizontal force for bearing wind or earthquake generation in house, is widely applied and is building In structure, however when using the methods of jacket-type reinforcing to existing building strengthening reconstruction, shear wall can be because of daylighting and building Function needs and increases door opening, window opening, but the arrangement of reinforcement of shear wall and size have been fixed, if because the functional requirement of owner To shear wall opening holes, the bearing capacity of shear wall in original structure will be largely reduced, therefore adopted after shear wall punching internal Necessary reinforcement measure is taken to ensure that the performance of original structure is particularly important.
In consideration of it, the research for reinforcing that shear wall is transformed reinforcing and its construction method just seems necessary.
Invention content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide the ruggedized construction that punches after a kind of shear wall large area, To solve the technical issues of intensity after shear wall punching internal will not weaken, and reduce material utilization amount, shortens the duration.
In order to achieve the above object, the utility model includes the shear wall being made up of two cylinders and a wall, is cut Power wall offers hole between two cylinders below wall, strengthening steel slab, wall are both provided on the side and bottom surface of wall Side and cylinder between fixed by the first angle steel, fixed by the second angle steel between the bottom surface and cylinder of wall.
It is connected by the first chemical anchor bolts between first angle steel and cylinder and wall, is passed through between the second angle steel and cylinder and wall First chemical anchor bolts connect.
It is connected by the second chemical anchor bolts between strengthening steel slab and wall.
The second chemical anchor bolts equidistant placement on the strengthening steel slab of wall side.
The second chemical anchor bolts on the strengthening steel slab of wall bottom surface are arranged in plum blossom.
The strengthening steel slab of two sides of wall leads to screw rod and runs through wall connecting together.
Epoxy resin is perfused between strengthening steel slab and wall.
The contact surface of wall and strengthening steel slab is hair side.
Compared with prior art, the utility model is by the opening holes on original wall body, and in the side and bottom surface of wall Upper setting strengthening steel slab is fixed between the side and cylinder of wall by the first angle steel, is passed through between the bottom surface and cylinder of wall Second angle steel is fixed, and can both have been met in old commercial building and underground parking strengthening reconstruction due to certain is needed in large span The needs that large area on wall punches are established, and meet the requirement of structural bearing capacity after reinforcing, the shear wall of other parts is made to carry Ability will not be weakened.Meanwhile the consumptive material simple in structure is less, stress is reliable, prevents take up original space, can be widely by industry Construction party of advocating peace is received, and then possesses more wide application prospect.

Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, the utility model includes the shear wall being made up of two cylinders 1 and a wall 2, shearing Wall offers hole 3 between two cylinders 1 below wall 2, strengthening steel slab 8, wall are both provided on the side and bottom surface of wall 2 It is fixed by the first angle steel 4 between the side and cylinder 1 of body 2, is fixed by the second angle steel 5 between the bottom surface and cylinder 1 of wall 2.
It is connected by the first chemical anchor bolts 6 referring between the first angle steel of Fig. 2 to Fig. 54 and cylinder 1 and wall 2, the second angle steel 5 It is connect by the first chemical anchor bolts 6 between cylinder 1 and wall 2, is connected by the second chemical anchor bolts 9 between strengthening steel slab 8 and wall 2 It connects, 9 equidistant placement of the second chemical anchor bolts on the strengthening steel slab 8 of 2 side of wall, second on the strengthening steel slab 8 of 2 bottom surface of wall Chemical anchor bolts 9 arrange that the strengthening steel slab 8 of 2 two sides of wall leads to screw rod 10 and links together through wall 2 in plum blossom, reinforce It is perfused with epoxy resin between steel plate 8 and wall 2, the contact surface of wall 2 and strengthening steel slab 8 is hair side.
The construction method of the utility model is as follows:
Step 1, positioning marking carry out unwrapping wire, and then the position that punches after determining using paying-off implement according to drawing;
Step 2, in cylinder 1 and 2 both sides of wall after dabbing is handled, to punch position positioning after carry out drilling and Borehole cleaning;
Step 3, install 2 both sides strengthening steel slab 8 of wall, install steel plate before according to design requirement, to the anchor of strengthening steel slab 8 Keyhole drills after being positioned, and is constructed using manual gluing steel bonding, and processed concrete surface is applied to simultaneously with spatula On strengthening steel slab 8, thickness 1-3mm, thick middle thin edge, then strengthening steel slab 8 is affixed on precalculated position;
Step 4, after strengthening steel slab 8 is pasted, 2 liang of side lower parts of wall are implanted into high-strength bolt 10, run through 2 liang of wall Side;
Step 5 carries out pressure injecting glue to bolt hole:It is implanted into medicament pipe in hole and pierces the second chemical anchor bolts 9, finally The fixed object after glue solidification, hardening;
Step 6 is required according to structural bearing capacity after setting support around hole 3, and the cutting for mouth that punch after progress is applied Work;
Step 7 pastes 2 bottom strengthening steel slab 8 of wall as required, and strengthening steel slab 8 is close to wall before strengthening with external bonding steel plate 8 Side carries out derusting and coarse processing, and hole-specifically injecting glue is carried out with air pump and injecting glue tank after being implanted into the second chemical anchor bolts 9;
