Abstract

The utility model relates to a reinforced bar positioning bracket for walls and floors in the cast-in-place reinforced concrete structure construction. The reinforced bar positioning bracket for walls comprises a straight rod and clamping rings connected with both ends of the straight rod and is used for controlling the thickness of the wall and the spacing of reinforced bars. The structure of the reinforced bar positioning bracket for floors is that a supporting base is connected with an upper and a lower supporting platforms which are respectively used for supporting the upper reinforced bar mesh of a stair plate and the lower reinforced bar mesh. The reinforced bar positioning bracket has simple structure, convenient use, low cost, and exact positioning; the work efficiency can be improved, the construction quality can be ensured, and the construction cost can be reduced.

Description

Reinforcement positioning support

The utility model belongs to technical field of buildings, and it relates to the reinforcing bar locating support of using in a kind of structure of reinforced concrete.

In the monolithic reinforced concrete structure construction, the control thickness of protection tier guarantees that promptly cage of reinforcement is in the tram, is a very important techniques requirement.If protective layer thickness is excessive, can influence structure tension performance; Protective layer thickness is too small, is unfavorable for antirust, anticorrosion, the fire prevention of reinforcing bar, then can reduce its durability.

At present, in the site operation of monolithic reinforced concrete structure, the method for control floor bar protective layer thickness adopts cement mortar cushion block or iron-clad horses stool bearing bar net sheet usually, to determine its position; The steel pole that control body of wall reinforcing bar adopts on reinforced mesh colligation cement mortar pad or weld length to equate with the wall thickness degree is located reinforcing bar.But there is following defective in these methods:

1. used supporter is subjected to the influence of people and ambient conditions by constructor's field fabrication, and its quality and physical dimension are difficult for guaranteeing that for example the cement mortar cushion block is often crushed because of strength deficiency, causes topping to reduce;

2. steel pole needs the pointwise welding, and workload is bigger, and time-consuming, effort, and efficient is low;

3. iron-clad horses stool and pole are all used reinforcement fabrication, and be very uneconomical.

The purpose of this utility model is that a kind of novel reinforcing bar locating support will be provided, and it can make things convenient for and determine reinforcement location exactly, guarantees construction quality, reduces operating expenses.

For achieving the above object, be designed to the reinforcing bar locating support of two kinds of patterns, a kind of reinforcing bar location that is used for body of wall, another kind is used for the reinforcing bar location of floor.Body of wall reinforcing bar locating support is the straight-bar support that is connected with collar, and the straight-bar of this support can be controlled thickness of wall body, and collar can be controlled bar space and the reinforcing bar distance to rod end, thereby can control desired protective layer thickness exactly; The floor bar locating support is to have the support of two cushion caps up and down, and last cushion cap has a plurality of arc grooves, and to support placing of reinforcement net sheet on the floor, following cushion cap is that a vertical bar body is to support underfloor placing of reinforcement net sheet.

Advantage of the present utility model: simple in structure, easy to use, accurate positioning can increase work efficiency and guarantee construction quality greatly, and this support is cheap, can reduce operating expenses.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Figure (1) is the elevation of the utility model body of wall reinforcing bar locating support embodiment;

Figure (2) is the vertical view of figure (1) embodiment;

Figure (3) is the elevation of another embodiment of body of wall reinforcing bar locating support;

Figure (4) is the elevation of floor bar locating support embodiment;

Figure (5) is the lateral view of figure (4) embodiment;

Figure (6) is the elevation of another embodiment of cushion cap under the floor bar locating support;

Figure (7) is the vertical view of figure (6) embodiment.

Referring to figure (1)～figure (3); the collar 2 that body of wall reinforcing bar locating support equals the straight-bar 1 of thickness of wall body by a length and is connected in two ends is formed; collar 2 can be split coupling or for scheming the opening sleeve that arc shown in (3) and straight shape plate combine, collar 2 centers are protective layer thickness and reinforcing bar radius sum to the distance on straight-bar 1 top.

The structure of collar 2 is not limited to above-mentioned two examples, and other form of structure that can block reinforcing bar also can.

Referring to figure (4), figure (5), the floor bar locating support is to connect two cushion caps up and down between two triangular in shape or trapezoidal identical bearings 3 of side, last cushion cap 4 is a vertical bar body, two ends are connected with the top of bearing 2 respectively, its table top has the arc groove of a plurality of different-diameters, to adapt to the reinforcing bar of different size; Following cushion cap 5 is a vertical bar body, is positioned at two bearings, 3 bottom surfaces middle parts, and it is connected with wherein a side bearing, and stays a vacancy between the opposite side bearing.

Referring to figure (6), figure (7), following cushion cap 5 also can be divided into two sections, and the bottom with side supports 3 is connected respectively, and two sections relative ends are the inclined-plane, form a rhombus gap therebetween.
