Description
Technical field
The invention belongs to the processing method fields in building pathology accident, and in particular to a kind of foundation platform beam reinforcing side
Method.
Background technique
In house because in foundation differential settlement pathology accident, existing strengthening of foundation method has a three categories: first
Class is that foundation cushion cap increases reinforcing, and the second class is foundation Pressure pile strengthening, third class foundation consolidation by grouting.For
The features such as existing building is reinforced, and is built than comparatively dense, and construction site is narrow, current method is for construction site
Very big requirement, therefore, these three types of methods implement relatively difficult, and difficulty of construction is big, and construction site is narrow, or even will affect
The building etc. on side.
Foundation platform beam reinforcement means of the present invention exactly solves above-mentioned problem, in order to not influence building outside variation,
Take and reinforced in Indoor environment, but for the residential house of the nineties, mostly use greatly be all structural system be strip footing
With brick setting basis, it can not summarize and improve by many years of experience, be for low layer foundation structure using basic section-increased method
Strip footing and brick setting basis are reinforced using foundation platform beam, are made whole building stable structure, can be constructed in Indoor environment,
It is easy to operate.
Summary of the invention
Object of the present invention is to aiming at the shortcomings of the prior art, propose a kind of foundation platform beam reinforcement means.The present invention is to build
It builds object foundation platform beam method for strengthening to administer in existing building structure pathology accident, mainly for building for foundation differential settlement
Build the narrow a kind of novel construction method used of object and construction site.It facilitates operation to construct, suitable for causing because of uneven settlement of foundation
The fast and stable of inclined building pathology accident simultaneously restores safe normal use.
In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme:
A kind of foundation platform beam reinforcement means, comprising the following steps:
Step 1: positioning earth excavation is to the bottom of foundation: according to site inspection and combine design requirement, using theodolite,
Level, Sopwith staff, steel tape carry out construction positioning in building, carry out repetition measurement after positioning, to guarantee accuracy, secondly, right
Localization region carries out earth excavation to the bottom of foundation；
Step 2: casting concrete bed course and smoothing out, the earthwork is hardened, is convenient for construction operation；
Step 3: plant anchor；
Step 4: reinforcing bar binding, system peace: being made by design diameter, reinforcing bar binding, system peace；
Step 5: formwork supporting plate: pressing construction requirement sawing sheet, carry out template peace；
Step 6: casting concrete foundation beam: strengthening of foundation foundation construction is completed in the molding of casting concrete reinforcement.
Compared with prior art, the invention has the following advantages that
The method of the present invention uses foundation platform beam reinforcing mode mainly to handle, and low layer civil buildings red line is closer, and house is peripheral
The problem of can not constructing, constructs in Indoor environment, solves the problems, such as that construction site is narrow, difficulty of construction is greatly reduced, and is taken
Material is easy, and structure is simple, quality controllable.
Detailed description of the invention
Fig. 1 is foundation platform reinforcement means flow chart of the present invention.
Specific embodiment
Present invention will now be described in detail with reference to the accompanying drawings., the description of this part be only it is exemplary and explanatory, do not answer
There is any restriction effect to protection scope of the present invention.
As shown in Figure 1, a kind of foundation platform beam reinforcement means, comprising the following steps:
Step 1: positioning earth excavation is to the bottom of foundation: according to site inspection and combine design requirement, using theodolite,
Level, Sopwith staff, steel tape carry out construction positioning in building, carry out repetition measurement after positioning, to guarantee accuracy, secondly, right
Localization region carries out earth excavation to the bottom of foundation；
Step 2: casting concrete bed course and smoothing out, the earthwork is hardened, is convenient for construction operation；
Step 3: plant anchor；
Step 4: reinforcing bar binding, system peace: being made by design diameter, reinforcing bar binding, system peace；
Step 5: formwork supporting plate: pressing construction requirement sawing sheet, carry out template peace；
Step 6: casting concrete foundation beam: strengthening of foundation foundation construction is completed in the molding of casting concrete reinforcement.
Specific step is as follows for the step 3:
1) positioning drilling: checking concrete members intensity, and the strength grade of concrete must not be lower than C15；It drills by positioning
Position, depth, aperture must change hole location if any trembleing or meeting the intensive clearence degree deficiency structure of original reinforcing bar again；To guarantee to fill
The effect anchored is waved in distribution, and the buried depth of reinforcing bar should not be less than 15 times of bar diameters, and boring aperture should be greater than bar diameter 4-
6mm, the width between lateral wall and concrete Member Lip should be no less than 5cm；
2) pore-forming is cleared up: should clear up immediately after pore-forming, the dust of hole wall is removed using steel brush, be portalled with electronic blowing interior
Dust, ponding should keep drying in hole, dip acetone using cotton yarn or dimethylbenzene wipes hole wall one time；As after borehole cleaning cannot and
When anchor plant, it is necessary to temporary plugging aperture prevents dust, sand grains etc. from falling into hole；
3) rebar surface is handled: being planted reinforcing bar or stud by anchor, must be used acetone clean the surface；Remove removing rust and oxide layer and oil
Dirty, sweat stain, processed reinforcing bar should avoid rust of living again in implant holes as early as possible；
4) match glue: building structure adhesive is two-component, and the mixing ratio by weight of the first and second components is 4:1, respectively accurate metering
After stir evenly；Allotment glue dosage should should not once be adjusted more depending on needed for scene, otherwise within the defined operating time not
Timely injection hole interplantation anchor, adhesive, which loses flowability, will will cause the waste of material；Forbid using any solvent to adhesive
It is diluted；
5) injecting glue, bar planting: deployed adhesive should be injected into hole as early as possible, and injecting glue amount is 1/2 to the 2/3 of hole depth；It is vertical
Reinforcing bar is inserted in the hole the bottom of to, is carried under rotation number up and down, bubble is discharged, guarantees that glue-line is full；The potting compound of lateral aperture, is answered
Glue is sent into the most deep in hole using proper implements, air is gradually discharged from inside to outside, reinforcing bar is inserted into；Reinforcing bar buries
Afterwards, the surrounding for positioning and blocking in time using early strong material aperture reinforcing bar, prevents adhesive outflow from influencing plumpness；
6) curing: the reinforcing bar in implant holes should conserve at normal temperature, must not disturbance；After being carried out again after 24 hours
Continuous construction operation；General room temperature was fully cured in 20 DEG C of adhesives at 3-5 days, and live sampling inspection should carry out after 5 days.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, several improvement can also be made, these improvement also should be regarded as guarantor of the present invention
Protect range.
