Abstract
The invention discloses a formwork supporting method for frame beam columns at a settlement joint between a main building and an attached building of a civil architecture. The formwork supporting method is characterized in that in a conventional fastening steel pipe support system, a frame beam column forming and reinforcing formwork system is laid, limit nuts are screwed up to abuts against inner formworks tightly by means of the characteristic of the adjustable degree of tightness of an upper wood wedge and a lower wood wedge, a split bolt rod system is tensioned, and the whole system acts integrally. The specific construction method comprises the steps that the fastening beam column plate steel pipe support system is erected; split bolt bars are installed; the wood wedges are installed; adjustment and reinforcement are conducted; and the formworks are detached. The formwork supporting method has the advantages that simultaneous formwork supporting construction for the two frame beam columns is fast and effective, the formworks are easy to erect and detach, the working efficiency is improved, the engineering cost is lowered, and all parameters such as the fracture surface geometric dimension, the surface evenness, the surface degree of finish and the surface straightness of the reinforced concrete frame beam columns in the pouring forming process meet code requirements surely.
Description
Technical field
The invention belongs to frame beam column formwork at technical field of building construction, more particularly to the main attached building subsiding crack of civil buildings
Method.
Background technology
In the long-term Construction practices of civil buildings, in the seam width at main attached building subsiding crack between two frame girders post often only
There is 100mm or so, two frameworks are while formwork construction is very difficult.But because same plane construction technology process is determined, most
It is well while formwork construction, damages work during damage.Generally just prop up in the case where any technology measure is not taken in prior art
Mould, casting concrete.Have the disadvantage, when concreting completes form removal again into a difficult problem, to take a lot of trouble and torn template open, frame
Post side surface of setting a roof beam in place is not bright and clean, out-of-flatness, especially ugly.Even sometimes cannot form removal, only violation operation gas welding fires
Template is burnt, is caused concrete surface to burst and is come off, damage frame beam column surface quality.
Therefore, how to invent one kind guarantee frame beam column in forming process is poured section physical dimension, surface smoothness,
The parameters such as fineness, glacing flatness all compliant are required, simple and effective form removal construction method, is art technology
The current technical issues that need to address of personnel.
The content of the invention
To overcome the deficiencies in the prior art, it is an object of the invention to provide framework at a kind of main attached building subsiding crack of civil buildings
Beam column mold method, formwork is quick, simple, effective, and form removal easily, improves efficiency of construction, reduces construction cost, frame beam column table
Face is smooth, bright and clean.
For achieving the above object, the present invention is adopted the following technical scheme that：Frame beam column at the main attached building subsiding crack of civil buildings
Mold method, is characterized in that the method is in conventional fastener formula steel pipe supporting frame system, to lay frame beam column molding and reinforcing
Template system, using the adjustable elastic characteristic of upper and lower timber wedge, tightens stop nut dieback inner template, is tensioned split bolt
Body of rod system, makes whole system collective effect, it is ensured that rc-frame-beam post in forming process is poured section physical dimension,
The parameters such as surface smoothness, fineness, glacing flatness all compliant are required；Concrete construction method enters in accordance with the following steps
OK：
Step one：Fastener type supporting beam column slab pipe support is set up, conventionally requires to be set up；Laying beam bottom girder
Nation's template, installs the reinforcing back of the body and holds together and standby redundancy, assembling reinforcement；
Step 2：Split bolt bar is installed, is worn while tightening the spiral shell of stop nut and tensioning split bolt bar in mould
It is female；
Step 3：Timber wedge is installed, that is, two normal wood chocks are installed, setting symmetrical above and below, elastic adjustment is moderately smooth；
Overwood chock, the sub- spacing of lower timber wedge are 600mm, and are staggered settings with split bolt bar, i.e. timber wedge and split bolt distance between tie rods
For 300mm；
Step 4：Adjustment is reinforced, and first, adjusts stop nut, it is ensured that beam cross dimensions；Secondly, timber wedge is tightened, and is twisted
The nut of tight split bolt bar, slowly beats timber wedge, and Shi Liang bottom girders nation template tightens up straight；It is physical dimension when beam, smooth
When the items technical parameter such as degree, glacing flatness all reaches code requirement, next process casting concrete is handed over；
Step 5：Form removal, when beam concrete strength reaches form removal requirement, first moves back lower timber wedge that comes loose, timber wedge in extraction
Son；After timber wedge has all been torn open, split bolt bar is cut off against template root, remove Feng Zhongliang side bars nation template.
Further improve, when split bolt bar is installed, the setting principle of split bolt bar：
1.) one split bolt is set when deck-molding is less than or equal to 500mm；
2.) when deck-molding is more than the road split bolts of 500mm~1000mm Shi She bis-；When split bolt is worn, wear while
The mat and stop nut of 50mm × 50mm × 4mm are tightened, split bolt spacing is arranged according to 600mm.
Further improve, the sub- length of described timber wedge is longer than deck-molding H by 1/3, superposition thickness is equal to gap width, plus man-hour throws
Light, and standard pairing, coincide up and down.
Compared with prior art, it is an advantage of the invention that making two framework fine strain of millet posts, simultaneously formwork construction becomes effective and rapid,
Easily prop up readily removable, improve work efficiency, reduce engineering cost, it is ensured that rc-frame-beam post is in forming process is poured
The parameters such as section physical dimension, surface smoothness, fineness, glacing flatness all compliant are required.
Description of the drawings
Below in conjunction with the accompanying drawings the invention will be further described.
