Abstract
The utility model discloses a cast -in -place reinforced concrete bottom of building board protective layer thickness construction control device comprises horizontal pole skeleton and support frame, its characterized in that: two plate -type support frame (2) are erect along length direction in both sides below rectangle horizontal pole skeleton (1), constitute a whole, arrange a plurality of arch concrete thick liquid packing semicircle orifice (3) along length direction support frame (2) below, and between two support frames (2) formation deposit concrete groove (4). The reinforcing bar face is placed to horizontal pole skeleton (1) top surface. Horizontal pole skeleton (1) and support frame (2) is makeed by the high density polyethylene plastics. The utility model discloses simple structure, light in weight, convenient to carry, and construction cost is low to it is closely knit not influence vibrating of cast in situ concrete bottom of the building board, has improved the outward appearance and the quality of cast in situ concrete bottom of the building board.
Description
Technical field
The utility model relates to building field, particularly a kind of cast-in-situ steel reinforced concrete bottom of the building plate protective layer thickness construction control device.
Background technology
Because the reinforcing bar base plate protection layer thickness on cast-in-place bottom of the building plate is generally all in 15 millimeter; more difficult control in concrete placement; existing market adopt concrete and waste marble more as the construction method of cushion block, but from actual service condition, often to fall flat.There is concrete mats bulk strength and do not reach designing requirement in simple use 1.5 cm x 1.5 centimetres of concrete pad; And the point cantact face of concrete pad and reinforcing bar is 0.5 cm, is easy to displacement and causes reinforcing bar to reveal muscle; And due to the intensity of concrete pad not high, be easy to fragmentation during construction, do not reach the effect effectively controlling concrete cover like this, clear up simultaneously and can affect concrete quality not in time.Adopt waste marble irregular as cushion block, be easy to displacement and cause dew muscle.Adopt these traditional two kinds of construction methods to the control of concrete cover and concrete quality control undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of cast-in-situ steel reinforced concrete bottom of the building plate protective layer thickness construction control device; the line utilizing this device can replace traditional point controlling change science into controls; make the thickness of cast-in-situ steel reinforced concrete bottom of the building plate topping reach effective control, improve the object of cast-in-situ steel reinforced concrete building base plate quality.
Formation of the present utility model: a kind of cast-in-situ steel reinforced concrete bottom of the building plate protective layer thickness construction control device; be made up of cross bar skeleton and bracing frame; it is characterized in that: below rectangular transverse rod skeleton, two plate shape bracing frames are erect on both sides along its length; form a whole; below bracing frame, arrange multiple arched concrete slurry along its length fill semicircle orifice, between two bracing frames, form fluid concrete groove.
Cross bar skeleton end face places reinforcing bar face.
Cross bar skeleton and bracing frame are made by high-density polyethylene plastics.
Compared with the prior art, the utility model structure is simple, lightweight, easy to carry, and construction cost is low, does not affect the vibration compacting of cast-in-situ concrete bottom of the building plate, improves outward appearance and the quality of cast-in-situ concrete bottom of the building plate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is the A-A sectional view of Fig. 1.
In figure 1, cross bar skeleton; 2, bracing frame, 3, arched concrete slurry fill semicircle orifice; 4, fluid concrete groove.
Detailed description of the invention
As shown in Figure 1, 2; a kind of cast-in-situ steel reinforced concrete bottom of the building plate protective layer thickness construction control device; be made up of cross bar skeleton and bracing frame; it is characterized in that: below rectangular transverse rod skeleton 1, two plate shape bracing frames 2 are erect on both sides along its length; form a whole; arrange along its length below bracing frame 2 between multiple arched concrete slurry filling semicircle orifice 3, two bracing frame 2 and form fluid concrete groove 4.
Cross bar skeleton 1 end face places reinforcing bar face.
Cross bar skeleton 1 and bracing frame 2 are made by high-density polyethylene plastics.
Claims (3)
