Abstract
The utility model discloses a simple reinforced bar welding positioner which is used for coaxially welding two reinforced bars. The simple reinforced bar welding positioner comprises a steel plate; eight reinforced bar positioning columns distributed in two rows are arranged on the steel plate in parallel; each reinforced bar positioning column is fixed on and vertical to the surface of the steel plate; the distance between the two rows of reinforced bars is equal to the diameter of the reinforced bar needing lengthened welding; and for each row of reinforced bar positioning columns, the distance between the two reinforced steel positioning columns positioned in the middle is five times larger than the diameter of the reinforced bar needing the lengthened welding.
Description
Technical field
The utility model relates in the welding procedure of a kind of linear pattern reinforcing bar spreading, and the instrument of control reinforcing bar axis of a weld on same straight line is mainly used in main muscle spreading welding procedures such as bridge, logical culvert.
Background technology
In bridge construction, the bridge span footpath is basically all greater than more than the 15m, and the factory length of reinforcing bar is generally 9-12m, and the former capital needs spreading.Reinforcing bar after the welding requires can be coaxial concentric, to guarantee reinforcing steel bar bear.But in actual reinforcing bar welding procedure process, accomplish factors such as the coaxial line welding is not easy control very much, and the workmen is mobile greatly in addition, technology is uneven, occur deviation easily, directly influence welding quality.
Summary of the invention
The purpose of the utility model is to the uppity problem of coaxial welding in the construction in the present reinforcing bar spreading welding a kind of reinforcing bar welded retainer to be provided, and uses this locator and can realize the coaxial welding between reinforcing bar easily and accurately.
The technical scheme of the utility model is following:
Simple and easy reinforcing bar welded retainer is used for two coaxial welding between the reinforcing bar, it is characterized in that: comprise a block plate, and on the said steel plate, laterally arrange two rows, four reinforcing bar reference columns of every row, every reinforcing bar reference column is all fixing and perpendicular to the surface of said steel plate.
In said every placing of reinforcement reference column, the spacing between two reinforcing bar reference columns of centre is greater than 5 times of the bar diameter that needs spreading welding.
Spacing between the said two placing of reinforcement reference columns need to equal the diameter of the reinforcing bar of coaxial welding.
The utility model is simple in structure, and is convenient and practical, can guarantee in the construction that reinforcing bar spreading when welding is can 100% coaxial, guaranteed the stress performance of reinforcing bar.

The specific embodiment
The utility model is used for two coaxial welding between the reinforcing bar.See Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises a block plate 1, on the said steel plate 1, and laterally arrange two rows, four reinforcing bar reference columns 2 of every row, every reinforcing bar reference column 2 is all fixing and perpendicular to the surface of said steel plate 1.In Fig. 1, two placing of reinforcement reference columns 2 are along the arranged outside of two straight lines parallel to each other (two dotted lines among Fig. 1).
In said every placing of reinforcement reference column, the spacing between two reinforcing bar reference columns 2 of centre is greater than 5 times of the bar diameter that needs spreading welding.
Spacing between the said two placing of reinforcement reference columns (being the spacing between two dotted lines among Fig. 1) equals the diameter of two reinforcing bars of coaxial welding.
In the utility model practical implementation process, described every reinforcing bar reference column can adopt short plain bar to be welded on the steel plate in a manner described.
See shown in Figure 4, the utility model in use, earlier with two end reinforced pre-bendings that need spreading, the angle [alpha] of pre-bending is calculated by following formula:
Wherein d is the diameter that needs the reinforcing bar of welding; 5d is the length of end reinforced pre-bending part.
The reinforcing bar 3 that pre-bending is good is put between the two placing of reinforcement reference columns 2 of simple and easy steel fixer by mode shown in Figure 4.Because the spacing between the two placing of reinforcement reference columns 2, need to equal the diameter of two reinforcing bars of coaxial welding, can not laterally move after therefore reinforcing bar to be welded is put into locator, thereby realize reinforcing bar 3 located lateral.Two reinforcing bars 3 are ridden against together through the two ends of pre-bending, make the termination of a reinforcing bar just be positioned at the preparatory corner of another root reinforcing bar, and it is seamless to guarantee that two reinforcing bar pre-bendings part can fit tightly, and has so just realized the reinforcing bar longitudinal register.Weld along two end reinforced joint places then.Like this two reinforcing bars after the welding can guarantee that promptly the axis (among Fig. 4 shown in the dotted line) of two reinforcing bars is located on the same line, and promptly the reinforcing bar after the welding is coaxial with one heart.
Claims (3)
