Abstract
A novel rebar split head is arranged between an upper plate rebar net and a lower plate rebar net in a rebar reinforced concrete plate, wherein the rebar split head is formed by bending a whole rebar into a frog shape, the head part is in a V-shape horizontally arranged on the upper plate rebar net, and the sharp part of the V-shape is slightly raised and is clamped forward on the rebar, the tail part and the claw part are two U-shapes with forward openings, one leg of each U-shape is supported on the lower plate rebar net, the other leg of each U-shape passes through a grid space of the upper plate rebar net and is connected with one end of the V-shape into a whole, and the width of the U-shape is adaptive to the distance between the upper plate rebar net and the lower plate rebar net. The novel rebar split head solves the problems that the thickness of a protection layer of the rebar reinforced concrete plate hardly reaches the requirements and the loading force of the rebar reinforced concrete plate is affected, resulting from the fact that the rebar deforms and a binding belt between the split head and the plate rebar net falls off after the traditional split head carries the construction load.
Description
Technical field
The utility model relates to a kind of for the steel bar horse-shaped bench between double-layer double-direction reinforcing bar in armored concrete slab.
Background technology
During armored concrete slab construction, split heads is a requisite construction auxiliary part in measure reinforcing bar.Between the upper and lower two-ply muscle net of split heads operated by rotary motion in plate; its objective is for upper layer plate-rib gauze pad is risen and fixed; make upper layer plate-rib net can bear the load that various construction activities are brought; and guarantee that upper layer plate-rib net has enough thickness of concrete cover, make protective layer thickness within the scope of regulation and stipulation.
General split heads shape has " several " font, " people " font and triangle at present; all need to carry out colligation on the net at plate muscle fixes; after upper layer plate-rib net surface has applied load; easily cause split heads reinforcing bar distortion or and plate muscle net between colligation silk come off; make within the protective layer thickness of upper and lower two-ply muscle net is difficult to reach the scope of regulation and stipulation, and the bearing capacity that affects armored concrete slab does not reach design load requirement.
Utility model content
The purpose of this utility model is to provide a kind of new reinforcing steel bar split heads; solve because traditional split heads is subject to the colligation silk that reinforcing bar produces between distortion and split heads and plate muscle net after working load and come off; thereby the protective layer thickness that causes armored concrete slab is difficult to reach code requirement, and affect the technical problem of armored concrete slab bearing capacity.
For achieving the above object, the utility model adopts following technical scheme:
A kind of new reinforcing steel bar split heads, be placed between the upper layer plate-rib net and lower plywood muscle net in armored concrete slab, this steel bar horse-shaped bench is the frog shape being formed by whole bar bending, its head is horizontal V font on upper layer plate-rib net, and the tip of its V font is micro-sticks up and is forward stuck on a reinforcing bar; Its afterbody and claw are two openings U fonts forward, one limb of each U font is supported on lower plywood muscle net, another limb of each U font is connected as a single entity through the mesh space of upper layer plate-rib net and an end of V font, and the spacing between the width of described U font and upper layer plate-rib net and lower plywood muscle net adapts.
The v-shaped openings width of described steel bar horse-shaped bench is less than the grid length of side of two upper layer plate-rib nets and is greater than the grid length of side of a upper layer plate-rib net.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is by several fonts, herringbone and the triangle supporting steel bar of common use, be modified into frog type split heads, this Novel barricade is made simple, reliably firm during use, only need be stuck between upper and lower two-ply muscle net, reduce the colligation workload of constructor to split heads, can also reduce the use number of split heads, effectively support levels reinforcing bar.
The utility model can not only guarantee construction safety and the construction quality of double-layer double-direction plate muscle, and cost is low, speed of application is fast, can the reduction of erection time, for other operations provide the scope of operation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the side-looking structural representation of use state of the present utility model.
Fig. 2 is the plan structure schematic diagram of use state of the present utility model.
Fig. 3 is the perspective view of use state of the present utility model.
Reference numeral: 1-upper layer plate-rib net, 2-lower plywood muscle net, 3-head, 4-afterbody and claw, 5-armored concrete slab.
The specific embodiment
Embodiment is referring to shown in Fig. 1～3: a kind of new reinforcing steel bar split heads, be placed between the upper layer plate-rib net 1 and lower plywood muscle net 2 in armored concrete slab 5, this steel bar horse-shaped bench is the frog shape being formed by whole bar bending, its head 3 is horizontal V font on upper layer plate-rib net 1, and the tip of its V font is micro-sticks up and is forward stuck on a reinforcing bar; Its afterbody and claw are two openings U fonts forward, one limb of each U font is supported on lower plywood muscle net 2, another limb of each U font is connected as a single entity through the mesh space of upper layer plate-rib net 1 and an end of V font, and the spacing between the width of described U font and upper layer plate-rib net 1 and lower plywood muscle net 2 adapts.
The v-shaped openings width of described steel bar horse-shaped bench is less than the grid length of side of two upper layer plate-rib nets 1 and is greater than the grid length of side of a upper layer plate-rib net 1.
Claims (2)
1. a new reinforcing steel bar split heads, be placed between the upper layer plate-rib net (1) and lower plywood muscle net (2) in armored concrete slab (5), it is characterized in that: this steel bar horse-shaped bench is the frog shape being formed by whole bar bending, its head (3) is horizontal V font on upper layer plate-rib net (1), and the tip of its V font is micro-sticks up and is forward stuck on a reinforcing bar; Its afterbody and claw are two openings U fonts forward, one limb of each U font is supported on lower plywood muscle net (2), another limb of each U font is connected as a single entity through the mesh space of upper layer plate-rib net (1) and an end of V font, and the spacing between the width of described U font and upper layer plate-rib net (1) and lower plywood muscle net (2) adapts.
2. new reinforcing steel bar split heads according to claim 1, is characterized in that: the v-shaped openings width of described steel bar horse-shaped bench is less than the grid length of side of two upper layer plate-rib nets (1) and is greater than the grid length of side of a upper layer plate-rib net (1).
