Abstract
The utility model discloses a hanging stool for the thickness-quality control of a cast-in-place concrete floor upper-layer plate-rib protecting layer and a concrete plate, which is characterized in that: the stool surface of the hanging stool is in the shape like a Chinese character 'ri', stool legs are fixed at the four corners of the stool surface, and the height of each stool leg is equal to the thickness of a cast-in-place floor plate. The stool surface is formed by welding short steel bars, and the length and the width of the stool surface are equal. A cast-in-place concrete floor upper-layer plate rib is bound below the steel bar in the middle of the stool surface. The stool legs and the stool surface are welded. In the utility model, residual steel-bar short heads in field steel-bar processing are mainly utilized as the steel bars for manufacturing the hanging stool, and the hanging stool is simple and convenient to manufacture; a steel-bar horse stool and a special supporting frame can be saved, and the cost is saved; a worker can walk on the hanging stool when concrete is poured, so that the disturbance for the plate rib is reduced; the upper-layer plate rib is bound below the steel-bar hanging stool, so that the thickness of an upper-layer rib protecting layer is ensured; the height of the steel-bar hanging stool is equal to the thickness of a cast-in-place plate, and the surface light is collected to the upper surface of the hanging stool, so that the thickness of the cast-in-place plate is ensured; and the steel-bar hanging stool can be repeatedly used in floors with the same specification.
Description
Technical field
The utility model relates to a kind of stool that hangs that is used for Cast-in-place concrete flooring top plate tendon protective layer and the quality control of concrete thickness of slab.
Background technology
Double-layer double-direction reinforcing bar top plate muscle adopts reinforcing bar split heads or special-purpose supporting frame to prop up usually in the present cast-in-place plate.Reinforcing bar split heads height is difficult to control, deviation is big, cost is higher; And the special-purpose supporting frame bearing capacity is relatively poor, is tramped easily.When installation of flooring pipeline and concreting; the workman is everlasting and walks about on the plate face reinforcing bar; cause plate muscle gross distortion, off normal and sagging; the effective height of negative muscle reduces; cause bigger influence for the cast-in-place structural quality; especially upper strata, cantilevered plate such as rain cover, balcony position tendon protective layer is excessive, even can cause the accident that concrete slab topples.
The conventional way of Cast-in-place concrete thickness of slab control is: employing is on Zhou Bianzhu, wall reinforcing bar and add vertical bar dowel between plate, and the horizontal control line of ejection is controlled.Owing to mostly adopt pumping during flooring concrete construction now, speed of perfusion is fast, and concreting is carried out at night usually, and the workman is difficult to flooring absolute altitude, planeness, thickness of slab are controlled in the allowable variation scope, and cause flooring mainly to have following quality problems: the top plate tendon protective layer is bigger than normal; Cast-in-place plate thickness deviation is big; Cast-in-place plate surface finish is poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of stool that hangs that is used for Cast-in-place concrete flooring top plate tendon protective layer and the quality control of concrete thickness of slab, has solved the problem of above-mentioned existence.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of stool that hangs that is used for Cast-in-place concrete flooring top plate tendon protective layer and the quality control of concrete thickness of slab is characterized in that: the described stool face that hangs stool is a day font, the Corner Strapped stool leg of stool face, and the height of this stool leg is identical with Cast-in-place concrete floor plate thickness.
Described stool face is welded by bar dowel, and its length equates with wide.
The colligation of described Cast-in-place concrete flooring top plate muscle is under the reinforcing bar in the middle of the stool face.
Described stool leg and the welding of stool face.
The utlity model has following advantage:
It mainly is to utilize on-the-spot reinforcing bar to process remaining reinforcing bar brachycephaly that the utility model is made the reinforcing bar that hangs stool, simple for production; Can save reinforcing bar split heads and special-purpose supporting frame, save cost; The workman can walk about hanging on the stool during concreting, has reduced the disturbance to the plate muscle; The colligation of top plate muscle is guaranteed the upper strata tendon protective layer thickness under reinforcing bar hangs stool; It is identical with cast-in-place plate thickness of slab that reinforcing bar hangs the stool height, and light is received to hanging the stool upper surface in the surface, has guaranteed the thickness of cast-in-place plate; Reinforcing bar hangs stool and can reuse in the same specification flooring; Can effectively avoid cantilevered plate positions such as rain cover, balcony to cause the quality accident of cantilevered plate fracture because of the upper strata tendon protective layer is excessive.

Fig. 2 uses schematic diagram for the utility model
Among the figure: 1-stool face, 2-stool leg, 3-top plate muscle, 4-Cast-in-place concrete floor plate
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Fig. 1-2; a kind of stool that hangs that is used for Cast-in-place concrete flooring top plate tendon protective layer and the quality control of concrete thickness of slab; it is characterized in that: the described stool face 1 that hangs stool is a day font, the Corner Strapped stool leg 2 of stool face, and the height of this stool leg 2 is identical with Cast-in-place concrete floor plate 4 thickness.
Described stool face 1 is welded by bar dowel, and it is long to equate with wide.
3 colligations of described Cast-in-place concrete flooring top plate muscle are under the reinforcing bar in the middle of the stool face.
Described stool leg 2 and 1 welding of stool face.
The field fabrication reinforcing bar hangs stool, adopts Φ 16 reinforcing bar welding productions, long * wide be 200 * 200, it is thick identical with Cast-in-place concrete floor plate 4 to hang the stool height, during the colligation of plate muscle the top reinforcement colligation is hung under Φ 16 reinforcing bars of stool centre, as shown in Figure 2 at reinforcing bar.The spacing of laying that reinforcing bar hangs stool is 800 * 800.When concrete was built, personnel can directly hang on the stool at reinforcing bar and walk about, and also can lay springboard on the stool hanging.During concreting, with long floating rule concrete surface is scraped to hanging the stool upper surface flush with reinforcing bar, concrete is received the light time reinforcing bar is hung stool taking-up turnover use.
