Abstract
The utility model relates to a spacer for cast-in-place slab horizontal steel bars, used in the building construction field. The spacer comprises an upper horizontal bent long rod and a lower horizontal bent long rod which are symmetric, and at least three vertical short rods distributed at intervals, wherein the upper end and the lower end of each vertical short rod are respectively connected with the upper horizontal bent long rod and the lower horizontal bent long rod in a welding manner; each horizontal bent long rod comprises a bent arc at the middle part and two hooked bent arcs reversely bent at the two ends; and the bent arc at the middle part and the two hooked bent arcs at the two ends are in the same plane. The spacer is placed between double layers of steel bars, supports double-layer steel bar meshes, requires no manual colligation fixing, improves the working efficiency, and is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of support, particularly a kind of cast-in-place plate level spacing of reinforcement spare for the cast-in-place plate of control, the horizontal reinforced mesh spacing of lower floor in the realm of building construction.
Background technology
In building engineering, for guaranteeing the floor load of cast-in-place plated construction, the level interval between necessary assurance cast-in-situ reinforced concrete slab (being called for short cast-in-place plate down) the double steel bar net sheet and the useful cross section design height of double steel bar.Traditional method is to lay split heads or " several ", " Z " font metal support muscle or finished product plastics bracer between cast-in-place plate double steel bar; Split heads is better to the support effect of reinforced mesh, but cost is higher; " several ", " Z " font metal support muscle or plastics bracer poor stability, positioning, off normal, overturning or crushed phenomenon all easily take place in concreting process, cause the level interval of reinforced mesh to can not get guaranteeing, common quality defects such as crack easily take place in the cast-in-place plate after the moulding, influence concrete cast-in-place slab structural safety and function of use.
Summary of the invention
The purpose of this utility model provides a kind of cast-in-place plate level reinforced mesh distance piece, to overcome the deficiency that the control of double steel bar net sheet spacing exists in the above-mentioned cast-in-place plate.
The cast-in-place plate level of the utility model spacing of reinforcement spare is made up of two horizontal curvature stocks and three vertical quarter butts spaced apart of upper and lower symmetry at least, and the two ends up and down of each vertical quarter butt are weldingly connected with upper and lower two horizontal curvature stocks respectively; The horizontal curvature stock comprises two hook-type curved arcs of the curved arc in middle part and two ends back-flexing each other, and two hook-type curved arcs at middle part curved arc and two ends all are positioned at same plane.
The middle part curved arc of described horizontal curvature stock constitutes 120-150 ° of bending angle.
Two hook-type curved arcs at described horizontal curvature stock two ends constitute 40-50 ° of bending angle respectively.
Described horizontal curvature stock diameter is Φ 6-Φ 8mm, and vertically the quarter butt diameter is Φ 8 or Φ 10 mm.Material is round steel or screw-thread steel.
When laying cast-in-place slab muscle, several distance pieces are placed between the double steel bar, distance piece plays a supportive role to double steel bar net sheet, after guaranteeing that cast-in-place board concrete is built moulding, level interval between its double steel bar net sheet and the useful cross section height of double steel bar adhere to specification, and guarantee concrete cast-in-place slab quality and structural safety.The on-the-spot waste and old reinforcement fabrication of the utility model distance piece utilization forms, and is simple in structure, easy to use, is placed between the double steel bar, do not need colligation again to fix, and saves manually the quickening progress.
Description of drawings
Fig. 1 is the three-dimensional perspective structure chart of cast-in-place plate level spacing of reinforcement spare.
Among the figure, 1-horizontal curvature bar, 1-1-middle part curved arc, 1-2-left end hook-type curved arc, 1-3-right-hand member hook-type curved arc, 2-vertically quarter butts, 3-arc welding contact.
The specific embodiment
Further specify example structure of the present utility model below in conjunction with accompanying drawing.
As Fig. 1, upper and lower two horizontal curvature stocks 1 are that the Φ 6 of 150mm or Φ 8 round steel or screw-thread steel bend and form by length.Horizontal curvature stock 1 comprises middle part curved arc 1-1, left end hook-type curved arc 1-2 and right-hand member hook-type curved arc 1-3; Middle part curved arc 1-1 is bent into the obtuse angle, and left and right two hook-type curved arcs are inverse bending each other, and the bending angle is 45 °.Middle part curved arc 1-1, left end hook-type curved arc 1-2 and right-hand member hook-type curved arc 1-3 all are positioned at same plane.Vertically quarter butt 2 two ends are connected with arc welding contact 3 with two horizontal curvature stocks 1 up and down, and the length of vertical quarter butt 2 is decided according to the distance between the horizontal mesh reinforcement sheet in the cast-in-place plate.
The utility model using method: install in the colligation forming process at cast-in-place slab muscle, by the definite spacing distance of working design requirement, this distance piece is plum blossom shape is placed between the double steel bar net sheet and gets final product.The horizontal curvature bar 1 that colludes for a short time of two ends band of symmetry, as the skeleton of cast-in-place plate level reinforced mesh distance piece, cast-in-place board concrete build Shi Buxu separately colligation fix, make very convenient.
