Abstract
The utility model relates to a pair of connecting clamps for thread reinforcing steel, which is composed of clamp members (1) and a bolt (2), wherein, each clamp member (1) is in a semicircle tube shape; the outer edges of both sides of each clamp member are provided with connecting boards with bolt holes; the inner wall of each clamp member (1) is provided with slot-shaped figures which are matched with external figures of the thread reinforcing steel; the two pieces of clamp members are clamped at a joint point of the thread reinforcing steel and are fastened and connected by the bolt (2). The utility model is suitable for the joint of the thread reinforcing steel having the 20-40 mm diameters and V-shaped or spiral-shaped external figures. Compared with the prior art, the utility model has the advantages of simple structure, convenient operation and use, reduction of equipment investment and enhancement of work efficiency.
Description
The utility model indented bars connects card, and it relates to a kind of detachable securing member of friction grip.
At present indented bars joint connected mode commonly used has following five kinds in the construction work: flash welding, overlap joint hand welding, electroslag welding, be processed into taper thread with the powerful banding of forcing press and with steel bar end, join the connection of screw thread hoop.Need welding machine and forcing press with the four kinds of methods of attachment of going forward, increased equipment investment, it is higher that another joins the cost of screw thread hoop, and processed complex, wastes time and energy.
For overcoming the weak point that above-mentioned prior art exists, the utility model provides a kind of indented bars simple in structure, easy to use to connect card.
The purpose of this utility model is achieved in that by two slit bamboo or chopped wood fasteners and is connected card with the indented bars that bolt is formed, two slit bamboo or chopped wood fasteners all are the semicircle tubulose, its both sides outer rim has the junction plate in strap bolt hole, and the fastener inwall has the flute profile decorative pattern, they respectively with the profile decorative pattern of indented bars coupling.Two slit bamboo or chopped wood fasteners are stuck in the joint of indented bars relatively, connect with bolt.
Description of drawings is as follows:
Fig. 1 is the structural representation of indented bars connection to card
Fig. 2 is the A-A schematic cross-section of Fig. 1
1-fastener 2-bolt 3-indented bars 4-index aperture among the above figure
Below in conjunction with accompanying drawing the utility model is further described: indented bars connects to be made up of two slit bamboo or chopped wood fasteners (1) and 4～8 cover bolts (2) card, fastener (1) is the semicircle tubulose, its both sides outer rim has the junction plate in strap bolt hole, fastener (1) inwall has the flute profile decorative pattern, the decorative pattern of two slit bamboo or chopped wood fastener inwalls is complementary with the profile decorative pattern of indented bars relatively and respectively, as chevron or spiral lamination.During use two slit bamboo or chopped wood fasteners (1) are stuck in the indented bars joint relatively, make the flute profile decorative pattern engagement of the profile decorative pattern and the fastener inwall of reinforcing bar, two slit bamboo or chopped wood fasteners (1) are fastenedly connected with bolt (2).The utility model can adopt hot-forging forming.For guaranteeing to dispatch from the factory in pairs, go up brill index aperture (4) at fastener (1), hang to sign and indicate reinforcing bar grade, diameter and decorative pattern.
The utility model compared with prior art, have simple in structure, easy for operation, reduce equipment investment, the advantage such as increase work efficiency, be applicable to the hot-rolled ribbed bars joint of φ 20～φ 40.
Claims (2)
1, a kind of indented bars connects card, it is characterized in that it is made up of fastener (1) and bolt (2), fastener (1) is the semicircle tubulose, its both sides outer rim has the junction plate in strap bolt hole, two slit bamboo or chopped wood fasteners (1) are stuck in the joint of indented bars (3) relatively, fixedly connected with bolt (2), an end of two slit bamboo or chopped wood fasteners (1) has corresponding index aperture (4).
2, connect card according to the described indented bars of claim 1, it is characterized in that the inwall of two slit bamboo or chopped wood fasteners (1) has the flute profile decorative pattern, they relatively and respectively with the profile decorative pattern coupling of indented bars.
