Abstract
The utility model discloses a reusable support frame for steel bar construction, which belongs to the technical field of building construction. The support frame comprises a rectangular square bar support frame; and support legs are arranged at the square bar cross-connection points at the lower part of the square bar support frame. The support frame provided by the utility model has the benefits as follows: the structure is simple, the operation is convenient, and the support height is easy to adjust; the quality problem of large deviation in the thickness of the negative moment reinforcement protecting layer of a cast-in-place concrete floor slab is solved, so that the construction quality of the cast-in-place concrete floor slab is improved; and meanwhile, a large quantity of steel bar split heads are saved, engineering cost is reduced, and construction efficiency is improved.
Description
Affiliated technical field
The utility model relates to a kind of reusable reinforcement construction bracing frame, belongs to technical field of building construction.
Background technology
At present, the reinforced bar support system of the structural slab of existing building mainly adopts dual mode.The first, on-the-spot reinforced bar support stool with the reinforcement fabrication different size, the reinforced bar support stool can only disposablely use, and wastes a large amount of artificial and reinforcing bar materials, and the support stool quality precision that different workmans make is wayward.The second, adopt the plastic support split heads, this not environmental protection of plastic support split heads product, plastics split heads intensity can not satisfy construction requirement fully in addition, and the plastic support split heads can not be played a supporting role after damaging, and influences workmanship.
The utility model content
For the unsettled deficiency of waste of material, quality that overcomes existing building operations split heads, the utility model provides a kind of reusable reinforcement construction bracing frame.
The technical scheme that its technical problem that solves the utility model adopts is:
Reusable reinforcement construction bracing frame comprises the square steel bracing frame of rectangle, and square steel interface point place is provided with supporting leg in square steel bracing frame bottom; The square steel bracing frame is the combination of 1-4 rectangle, adopts 15mm * 15mm square steel to make.
The beneficial effects of the utility model are that simple in structure, easy to operate, bearing height is adjusted easily; Having solved influences the big quality difficult problem of cast-in-place concrete floor negative tendon protective layer thickness deviation, thereby has improved the construction quality of cast-in-place concrete floor; Save a large amount of reinforcing bar stirrups simultaneously, reduced engineering cost, improved efficiency of construction.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is implemented schematic diagram;
Component and numbering among the figure:
1-square steel bracing frame; The 2-supporting leg; The 3-top mat; 4-lower floor steel mesh reinforcement.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, reusable reinforcement construction bracing frame comprises the square steel bracing frame 1 of rectangle, square steel bracing frame 1 bottom the welding of square steel interface point place be provided with supporting leg 2.Square steel bracing frame 1 is the combination of 1-4 rectangle, adopts the square steel of 15mm * 15mm to make.
The square steel bracing frame 1 of present embodiment is the combination of 3 rectangles, and its length of side is provided with length by the negative muscle of plate and determines; Supporting leg 2 length are the appropriate length that go out according to the concrete floor THICKNESS CALCULATION, and supporting leg 2 is Φ 12mm or Φ 16mm round steel.
As shown in Figure 2, before concreting, reusable reinforcement construction bracing frame is placed on the template, wherein supporting leg 2 is supported on the template; The square steel bracing frame 1 that sets in advance is close to the upper surface of the negative muscle of plate of top mat 3, and negative muscle of plate and 1 colligation of square steel bracing frame is firm, and lower floor's steel mesh reinforcement 4 is below top mat 3.
After this bracing frame laying colligation is finished, carry out concreting, the upper surface of the upper surface of concreting and square steel bracing frame 1 is same plane; Remove this bracing frame before the initial set, the concrete surface usefulness mortar that will remove then behind this bracing frame is floating.
Adopt this new job practices, fixed the position of the negative muscle of cast-in-place concrete floor effectively, this has just solved from root influences the big quality difficult problem of cast-in-place concrete floor negative tendon protective layer thickness deviation, thereby has improved the construction quality of cast-in-place concrete floor; Save a large amount of reinforcing bar stirrups simultaneously, brought significantly economic benefit, satisfied the construction needs of all kinds of concrete structure plates.
