Description
Technical field
The utility model relates to field of civil engineering, relates in particular to a kind of bolt auxiliary connection anchor clamps.
Background technology
In the reinforced concrete structure, the connection of the especially main muscle of reinforcing bar is an important problem.The engineer is seeking a kind of method of easy reliable, cheap connecting reinforcement always.
Early stage reinforcing bar connects continues to use strapping always, this method worker's method is easy, equipment is simple, and weatherproof, but be to use the strapping connecting reinforcement to have bigger drawback, embody a concentrated reflection of following 3 points: the first, the waste steel, strapping requires in certain " lap of splice " of joint reservation; The second, joint power transmission effect is bad, and the off-centre of reinforcing bar connects can produce additional shear stress; The 3rd, junction reinforcing bar density is big, and cast is vibrated and brought difficulty to concrete.
At present, connecting method for reinforcing bars mainly contains and is welded to connect and mechanical connection two big classes.6 kinds of methods such as reinforcing bar resistance spot welding, reinforcing bar flash butt welding, reinforcing bar arc welding, steel bar flux press welding, steel bar gas, built-in fitting reinforcing bar submerged arc pressure welding have been comprised among " reinforcing bar welding and control of acceptance " JGJ18-2003.The welder technology level often influences welding quality in the arc welding, and the waste steel, and speed of application is slow; Flash welding is operation at the construction field (site); Though the saving steel are compared in the above several methods of attachment of electroslag pressure welding, power consumption is big, need set up supply line specially; The gas pressure welding complex procedures is subjected to climatic effect big, and has work with torches dangerous.Above-mentioned several method of attachment all needs joint location is staggered, and the splice sectional area in the same cross section and the percentage of the reinforcing bar gross area all have strict restriction, make troubles to construction.
Since the seventies in last century, America and Europe, Japan, China etc. research and develop out multiple reinforcing steel bar machinery method of attachment, as technology such as cold extrusion interconnection technique, taper thread connection, straight thread connections.Compare with solder technology, the advantage outstanding behaviours of mechanical connection is not at following 3 points: affected by environment, be not subjected to materials limitations, be not subjected to diameter restrictions.
Rebar connecting technology is mainly the technology of being threaded at present, and this technology has the industrialization degree height, the field operation amount is little, construction technology is simple.But existing screw thread steel interconnection technique all is to form screw thread on the parent material of reinforcement rebar basis, no matter forming mode how, quality of connection all is difficult to avoid following defective: influenced greatly by the reinforcing bar profile; The reinforcing bar section has dwindling in various degree; Reinforcing bar material and mechanical property have certain influence; Thread quality is difficult to guarantee fully; The screw forming operation is many, and equipment needed thereby requires high.In a word, utilize the intensity that is threaded of reinforcing bar body direct forming to be difficult to complete and mother metal etc. by force at present, the reinforcing bar junction often becomes weak link, causes very big waste.
Develop a kind of reinforcing steel bar connecting device in the recent period, connect by the reinforcing bar auxiliary connection, described reinforcing bar auxiliary connection comprises sleeve and bolt, and described sleeve and bolt weld together with corresponding reinforcing bar respectively.But because sleeve and bolt volume are smaller, it is very inconvenient to be fixed up, and influences itself and the welding of corresponding reinforcing bar, can't guarantee welding quality.
The utility model content
In view of this, technical problem to be solved in the utility model provides a kind of bolt auxiliary connection anchor clamps, can be used for fixing bolt or sleeve in the bolt auxiliary connection, makes it to be convenient to be connected with reinforcing bar.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of bolt auxiliary connection anchor clamps, described bolt auxiliary connection anchor clamps comprise an anchor clamps handle, an end of described anchor clamps handle is fixedlyed connected with anchor clamps bolt or chuck sleeve.
In above-mentioned bolt auxiliary connection anchor clamps, an end of described anchor clamps handle is connected with the anchor clamps bolting, and the other end is fixedlyed connected with chuck sleeve.
In above-mentioned bolt auxiliary connection anchor clamps, described anchor clamps handle and anchor clamps bolt or anchor clamps cover connect butt welding by sudden strain of a muscle and fixedly connected.
In above-mentioned bolt auxiliary connection anchor clamps, described anchor clamps handle and anchor clamps bolt or chuck sleeve are fixedly connected by welding.
In above-mentioned bolt auxiliary connection anchor clamps, described chuck sleeve and anchor clamps handle weld side are provided with a chuck sleeve substrate screw rod.
The beneficial effects of the utility model: the utility model bolt auxiliary connection clamp structure is simple, practical and convenient, can be used for fixing bolt or sleeve in the bolt auxiliary connection, makes it to be convenient to be connected with reinforcing bar, guarantees welding quality.
Description of drawings

Fig. 2 is that fixing bolt to be welded is prepared the schematic diagram that welds with corresponding reinforcing bar;
Fig. 3 is that fixing sleeve to be welded is prepared the schematic diagram that welds with corresponding reinforcing bar;
Among the figure: 1-reinforcing bar, 2-bolt, 3-sleeve, 31-sleeve substrate screw rod, 4-bolt auxiliary connection anchor clamps, 41-anchor clamps handle, 42-anchor clamps bolt, 43-chuck sleeve, 431-sleeve substrate screw rod, 5-clamping tool.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation clearly and completely:
See also Fig. 1, this bolt auxiliary connection anchor clamps 4 comprise that two end-grain cutting polish whole anchor clamps handle 41, anchor clamps bolt 42 and chuck sleeve 43.Fixedly connected with chuck sleeve 43 with described anchor clamps bolt 42 respectively in the two ends of described anchor clamps handle 41.Described chuck sleeve 43 and anchor clamps handle 41 weld side are provided with a chuck sleeve substrate screw rod 431, with the be connected area of expansion chuck sleeve 43 with anchor clamps handle 41, to improve their bonding strength.
The manufacture method of the utility model bolt auxiliary connection anchor clamps 4 is as follows:
See also Fig. 1, add builder's temporary shed, at first make anchor clamps handle 41 at engineering site.Anchor clamps handle 41 adopts the spiral of Φ 20 general on the engineering, and length is 500mm.Two end-grain cutting of spiral are polished whole just can make anchor clamps handle 41.Then, M20 type anchor clamps bolt 42 of a termination points of described anchor clamps handle 41 welding, a M20 type of another termination means of spot welds chuck sleeve 43 of described anchor clamps handle 41.Certainly only in an end points weld jig bolt 42 or a chuck sleeve 43 of anchor clamps handle 41.
The using method of the utility model bolt auxiliary connection anchor clamps is as follows:
See also Fig. 2, bolt 2 screws the chuck sleeve 43 at described bolt auxiliary connection anchor clamps, clamps these auxiliary connection anchor clamps and comes indirect securement bolt to be welded 2 by adding clamping tool 5.
