Abstract
The invention relates to a support frame for guaranteeing the thickness of a protective layer of a floor slab and a construction method thereof. The support frame comprises a bracket welded by a plurality of galvanized steel tubes on a plane as well as a plurality of supporting feet being vertical to the plane of the bracket; wherein, the supporting feet are supported on a floor slab template arranged at the bottom of the floor slab, and the lengths of the supporting feet can ensure the plane of the bracket to be higher than that of a surface reinforcing rib of the floor slab. The invention adopts the bracket with a structure of 'B'-shape of 'MU'-shape like a Chinese character in a creative way, so that the processing and construction are convenient. As the lengths of the supporting feet can ensure the plane of the bracket to be higher than that of the surface reinforcing rib of the floor slab, the surface reinforcing rib of the protective layer of the floor slab can be effectively protected, and the thickness of the protective layer of the floor slab is guaranteed. The invention also creatively provides the construction method for manufacturing and installing the support frame, thus well controlling and improving the construction quality.
Description
Technical field
The present invention relates to a kind of setting bracket that guarantees the concrete floor protective layer thickness, particularly a kind of can effectively guarantee concrete pouring after, the bracing frame that the protective layer thickness of floor still keeps.The invention still further relates to the job practices of above-mentioned bracing frame.
Background technology
At present, buildings in general all adopts reinforced concrete floor, and the structure of its topping is for setting up the upper reinforcement (gluten) and the lower rebar (end muscle) of configuration in length and breadth on slab form.In order to protect these glutens and end muscle not to be destroyed; the patent No. is that 200720127870.0 document discloses a kind of concrete floor reinforced bar support device; described eyelid retractor is arranged in the reinforced concrete floor; its upper support district is supported on the below of the upper reinforcement in the floor, and its underpart feet is supported on the slab form of floor slab bottoms.The inventor finds, though the end muscle that above-mentioned technology can reasonable protection protective layer of floor slab, have following shortcoming: 1, structure is complicated, and processing and installing is all relatively wasted time and energy; 2, because this eyelid retractor is positioned at the below of gluten, therefore when staff's assembling reinforcement and fluid concrete, be difficult to avoid artificial trampling to cause the bending of floor gluten, so the gluten of protective layer of floor slab is difficult to be protected.
Summary of the invention
Goal of the invention of the present invention provides a kind of bracing frame that guarantees thickness of protective layer of floor slab, and enough protections is provided for the gluten of protective layer of floor slab.
Another object of the present invention provides the job practices that can fully guarantee construction quality of above-mentioned bracing frame, with best realization first goal of the invention of the present invention.
Technical scheme of the present invention is: a kind of bracing frame of protecting the concrete floor topping; comprise the support that the several coating steel pipes on the plane are welded; and most with the vertical feet in plane, described support place; wherein; described feet is supported on the slab form of floor slab bottoms, and the length of described feet is enough to guarantee that plane, described support place is higher than the plane at floor gluten place.Therefore, when staff's assembling reinforcement and fluid concrete, what trample is bracing frame of the present invention, and the gluten of bracing frame below has then obtained good protection.
Described support is made of 5 steel pipes on the plane, and the support that these 5 steel pipes constitute is that a plane is " day " word, and described feet is 6; Or 6 steel pipes on plane, the support that 6 steel pipes constitute is the support of a plane " order " font, described feet is 8; The support of this shape has processes and transports all advantage very easily.
Described feet is separately fixed at the tie point place between described steel pipe and the steel pipe.This structure not only simply but also practical.
Support frame as described above also comprises some bundle silks, is used for fixedlying connected with the gluten of protective layer of floor slab.
The steel pipe that the support of support frame as described above adopts is the coating steel pipe of diameter 2.5cm, and it is the reinforcing bar of 12mm that the feet of support frame as described above adopts diameter.
A kind of job practices of protecting the concrete floor topping comprises preparation bracing frame technology and bracing frame technology is installed.
Above-mentioned preparation bracing frame technology comprises the steps:

(4) adopt Abrasive cutting off machine to carry out blanking processing;
(5) adopt the electric welding machine manual welding between each node;
(6) carry out dimension control with the standard of each several part permissible variation in dimension ± 5mm.
Above-mentioned installation bracing frame technology comprises the steps:
(7) after the reinforcing bar binding for the treatment of protective layer of floor slab finishes, the bracing frame of handling to the job site is placed on the slab form that ties reinforcing bar, from the about 300mm of distance of primary and secondary beam;
(8) gluten of protective layer of floor slab is mentioned with pricking silk the galvanized pipe colligation on the support of itself and bracing frame is firm;
(9) treat the hidden examination of reinforcing bar after, build concrete immediately;
(10) untie the bundle silk before the concrete initial set, bracing frame is taken out;
(11) treat that this concreting finishes after, the concrete laitance above the bracing frame is cleaned out, hand over materialman to take good care of, for using next time.
Beneficial effect of the present invention is:
1, the creationary support that has adopted " day " or " order " font structure, processing and construction are all very convenient.
2, because the length of feet of the present invention is enough to guarantee that plane, described support place is higher than the plane at floor gluten place, therefore can effectively protect the gluten of protective layer of floor slab, guaranteed the thickness of protective layer of floor slab.
3, the creationary construction technology of making and above-mentioned bracing frame being installed of having invented makes construction quality obtain better controlled and raising.
