Abstract
The utility model provides a lossless connection fastener for a steel reinforcement cage. The lossless connection fastener is used for connecting steel bars at nodes of the steel reinforcement cage, and comprises a U-shaped bolt, a pressing iron sheet and two screw caps corresponding to two screws of the U-shaped bolt, wherein screw threads are formed at the ends of two screws of the U-shaped bolt; and two screw holes corresponding to the two screws of the U-shaped bolt are formed on the surface of the pressing iron sheet. The lossless connection fastener is used for connecting the connecting steel bars at the nodes of the steel reinforcement cage; due to the U-shaped bolt and the pressing iron sheet, the steel bars to be connected can be tightly attached effectively and stably, so that the strength of the nodes of the steel reinforcement cage is improved, the steel bars are prevented from sliding, and the safety is improved; furthermore, the lossless connection fastener is convenient to manufacture, the machining efficiency of the steel reinforcement cage is improved, the labor cost and the labors are saved, and the problems of low quality of the traditional electrically welded steel reinforcement cage, time consumption and the like are solved.
Description
Technical field
The utility model relates to the connection fastener of the realm of building construction, refers in particular to a kind of harmless connection fastener that the reinforcing cage reinforcing bar connects that is used for.
Background technology
The existing processing that is used for the reinforcing cage of diaphragm wall all is to adopt the electric welding welding.Its inefficiency; Fabrication and processing is time and effort consuming extremely, and especially reinforcing bar produces phenomenons such as " stinging meat ", " rosin joint ", " dry joint " often owing to operator's maloperation in manufacturing process; And inspection difficulty; Rectification is difficult for, and has increased the potential safety hazard of operation simultaneously, so be badly in need of solving the connectivity problem to the reinforcing cage reinforcing bar.
The utility model content
The purpose of the utility model provides a kind of easy to operate, simple structure, reinforcing bar is not had the connection fastener of damage, to solve reinforcing bar damage that electric welding causes, to be difficult for problem such as rectification.
For realizing above-mentioned purpose, the utility model provides the harmless connection fastener of a kind of reinforcing cage, comprising:
One U-bolt, the end of two screw rods of said U-bolt is respectively equipped with screw thread;
One foundary weight sheet, said foundary weight sheet are provided with two screws corresponding with the two screw rods of said U-bolt;
And two nuts that cooperate said U-bolt two screw rods:
The improvement of the utility model is; The inner ring surface length of said U bolt need to equal the diameter sum of connecting reinforcement to add the thickness of the above foundary weight sheet and the thickness of said nut; And length in reserve 1 0mm～20mm; The inner ring surface width of said U bolt need to equal the diameter of connecting reinforcement, and length in reserve 5mm.
The improvement of the utility model is that also said screw flight length is 50mm.
The utility model is used for the connection between each node place reinforcing bar of reinforcing cage, can effectively stably be adjacent to the required reinforcing bar that is connected with the foundary weight sheet, guarantee the intensity of reinforcing cage node, and prevent the slippage of reinforcing bar, increased safety through U bolt.Simultaneously the utility model is easy to make, has improved the working (machining) efficiency of reinforcing cage greatly, has practiced thrift labour cost and labour, has solved electric welding in the past and has made of poor quality, the problem such as lose time of reinforcing cage.

Fig. 2 is the structural representation of the utility model U bolt.
Fig. 3 is the structural representation of the utility model foundary weight sheet.
Fig. 4 is used for reinforcing bar and reinforcing bar structural representation connected vertically for the utility model.
Fig. 5 is used for the structural representation that reinforcing bar is connected with suspension centre for the utility model.
Fig. 6 is used for reinforcing bar and strengthens the structural representation that truss is connected for the utility model.
The specific embodiment
Referring to shown in Figure 1, the harmless connection fastener of the utility model reinforcing cage comprises U bolt 10, foundary weight sheet 20 and nut 30.
Cooperate Fig. 2, shown in Figure 3, the end of two screw rods 11 of U bolt 10 is respectively equipped with screw thread 12, and the length of screw thread 12 is 50mm, and the key diameter of U bolt 10 is 8mm～20mm according to its strength characteristic.The surface of foundary weight sheet 20 is provided with two screws 21 corresponding with the two screw rods of U-bolt 10 11; The length A of the inner ring surface 13 of U-bolt 10 need to equal the diameter sum of connecting reinforcement to add the thickness of foundary weight sheet 20 and the thickness of nut 30; And length in reserve 10mm～20mm; The width B of the inner ring surface 13 of U bolt 10 need to equal the diameter of connecting reinforcement, and length in reserve 5mm.During use, U-bolt 10 colligations on the reinforcing bar at each node place of reinforcing cage, are inserted in foundary weight sheet 20 in the screw rod 11 again, fix through nut 30 at last.
Below specifically introduce the utility model each mode of occupation in reinforcing cage is made.
When reinforcing bar was connected with parallel reinforced steel bar, U-bolt 10 direct colligations were fixed with foundary weight sheet 20 and nut 30 on two reinforcing bars that needs connect again.In conjunction with shown in Figure 4, reinforcing bar 40 and reinforcing bar are during 40 vertical connections, and U-bolt 10 connects by 45 degree oblique angles, fix with foundary weight sheet 20 and nut 30 again.
In conjunction with shown in Figure 5, when reinforcing bar 40 was connected with suspension centre 50, U-bolt 10 carries out colligation with suspension centre 50 and reinforcing bar 40 to be fixed, and prevents suspension centre 50 slippages.
In conjunction with shown in Figure 6, reinforcing cage is strengthened also being connected with U-bolt 10 between truss 60 and the reinforcing bar 40 and is fixed, and reinforcement truss 60 is " Z " shape.
Each important node employing the utility model of whole reinforcing cage can guarantee the resistance to overturning of reinforcing cage and enough strength and stiffness, with lifting and the designing requirement that satisfies reinforcing cage after reinforcing.
More than the disclosed several specific embodiments that are merely the utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the utility model.
