Abstract
The invention discloses a hole reserving construction method for a tightly-fixed steel sleeve, which adopts a hole-reserved steel sleeve to replace a PVC sleeve which is adopted in the traditional reserving step, has the characteristics of recyclability, no nail remaining at a reserved hole, nice appearance and remarkable economical benefit, and is easy in assembly. According to the construction drawing and a structure datum point, the center of the hole is determined and used as the central position for a fixed screw, and the reserved sleeve is fixed through the tightening effect of the fixed screw. In the method, the deflection of the center of the vertical hole is adjusted by utilizing a plumb line or a laser plummet apparatus every other 5 to 8 layers, and the center of the bottom hole is led to the bottom of an upper formwork to position an upper hole, so that the deflection of the centers of two holes which are symmetric up and down caused by errors of a civil support formwork can be effectively avoided. According to the invention, a reserved hole of a finished product sleeve can be fixed by a screw so as to achieve the aims of time conservation and rapidness in assembly.
Description
Technical field
The present invention relates to a kind of reserving hole job practices, particularly relate to a kind of tightening formula steel sleeve reserving hole job practices.
Background technology
In building water supply, draining and the heating engineering work progress, often run into problems such as inevitable installation (sanitary apparatus, equipment and pipeline) reserving hole.Especially in sub-district dwelling house, hotel, hotel equivalent type building operations structure stage that kitchen guarding or pipeline are comparatively concentrated, the characteristics that this type of hole is reserved are in the set of specifications, workload is big, the number of turnover is many.Conventional construction technology of boxing out with pvc pipe or tub can be out of shape working security and less economical by hole for repeating pre-buried hole in a large number.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly can effectively control the tightening formula steel sleeve reserving hole job practices that hole can not be out of shape for repeating pre-buried hole in a large number.
In order to solve the problems of the technologies described above, tightening formula steel sleeve reserving hole job practices provided by the invention, its construction sequence is as follows:
(1), preparation of construction:
(1.1), be familiar with construction drawing, drawn the pipeline hole reservation figure and the steel sleeve construction drawing of boxing out, carry out the preparation of confiding a technological secret to the operator;
(1.2), configuration needs the steel sleeve of boxing out of location, makes the drawing steel sleeve processing and fabricating of boxing out by the code requirement and the steel sleeve of boxing out, the steel sleeve of boxing out is made up of positioning screw, positioning screw base, the steel sleeve body of boxing out, sleeve pipe top cover and nut;
(1.3), configuration box out steel sleeve location construction required worker's facility and material, and guarantee that all appliance material are qualified, effective;
(2), the steel sleeve positioning and fixing of boxing out:
(2.1), central point sign:
According to construction drawing and the structure reference point of boxing out, utilize invar tape, Steel Ruler and spirit level to determine this layer central point of steel sleeve of boxing out, and carry out mark;
(2.2), base location construction:
Position construction according to mark, with markers align positioning screw base center, guarantee positioning screw on the positioning screw base at the center of reserving the hole, positive negative error must not be fixed on the positioning screw base on the template with wood screw greater than 2mm;
(2.3), box out steel sleeve fixed installation:
According to the drawing of boxing out, choose the steel sleeve body of boxing out of respective model specification, the steel sleeve body of will boxing out places on the template, with spirit level the steel sleeve body of boxing out is carried out levelling capturing, cover the sleeve pipe top cover then, screw the nut compressing steel sleeve body of boxing out, make it fixed with spanner;
(2.4), the steel sleeve external surface brush oil of boxing out:
The steel sleeve body freezes solidly in the concrete in order to avoid boxing out, be ready to a keg used oil or a release agent in advance, after the steel sleeve body of waiting to box out installs, evenly brush at least one time, with the convenient steel sleeve body of boxing out of removing in the future at the external surface that the steel sleeve body of boxing out contacts with concrete;
(3), multilayer sleeve is proofreaied and correct:
Construction is every the 5-8 layer, utilize plumb bob or laser plummet apparatus, skew to vertical hole central point is adjusted, at the bottom of bottom hole central point caused upper former, carry out the location of upper strata hole with this, can effectively avoid laterally zygomorphic hole to cause the skew at hole center because of the error of civil engineering formwork;
(4), the dismounting of box out sleeve pipe:
When civil engineering is finished concreting, when reaching design strength 50%, the steel sleeve of boxing out is promptly dismountable; Earlier nut is unclamped, open the sleeve pipe top cover, remove the wood screw of stationary positioned screw rod base; Cover the sleeve pipe top cover again, hitting with a hammer boxes out makes around the steel sleeve body it loosening, along positioning screw it is taken out again; Collect at last and clean out, all auxiliary material all reclaim, in order to substructure construction recycling.
Adopt the tightening formula steel sleeve reserving hole job practices of technique scheme, the employing PVC sleeve pipe that steel sleeve replaces traditional reservation stage to adopt of boxing out has simple installation, reusable edible, reserve the hole nothing left and stay iron nail and attractive in appearance, the tangible characteristics of economic benefit.According to construction drawing and structure reference point, determine the central point of hole, and with this center as standing screw, and the tightening effect by standing screw, the fixing sleeve pipe of reserving.This worker's method is every the 5-8 layer, can utilize plumb bob or laser plummet apparatus, skew to vertical hole central point is adjusted, at the bottom of bottom hole central point caused upper former, carry out the location of upper strata hole with this, can effectively avoid laterally zygomorphic hole to cause the skew at hole center because of the error of civil engineering formwork.This worker's method utilize screw rod fixedly the finished product sleeve pipe box out, reach the purpose that the province that saves time installs rapidly.
Beneficial effect of the present invention is as follows:
1, cost efficiency, considerable benefit: the steel sleeve spoilage of boxing out is extremely low, can recycle.Raw material and the manufacturing cost of reserving sleeve pipe have been saved greatly.
2, easy and simple to handle, fixed: as only need to locate tightening during installation, need not other auxilliary materials.The one man operation can finish whole installations in 2 minutes.
3, energy-conserving and environment-protective, high-efficiency low-carbon: this kind way is replaced the PVC material in the traditional method, and the use of both having saved the PVC material has reduced auxilliary material consumption such as iron nail, iron wire again, realizes environmental protection and energy saving, green construction.
4, widely applicable, The goose hangs high: be widely used in various construction works, it is better especially to be applied to the big building body effect of holes reservation engineering quantitys such as dwelling house, hotel.
This worker method is applicable to that the concentrated hole reservation engineering of specifications and models is had enough to meet the need construction in the building structure.
In sum, the present invention be a kind of for repeat in a large number pre-buried hole can effectively control hole can distortion and the tightening formula steel sleeve reserving hole job practices of cost efficiency, considerable benefit, easy and simple to handle, fixed, energy-conserving and environment-protective, high-efficiency low-carbon, widely applicable, The goose hangs high.
