Abstract
The utility model relates to a wedge clamp device using two coupled centre gripping parts, which are respectively connected with the steel bars to be connected and connected with the steel bars by a or a plurality of connecting pieces used in connecting two centre gripping parts to reach the objective of steel bar connection. The larger the tensile force of the connected steel bars, the larger the clamping force exerted by the gripping parts with the wedge clamp device on the steel bars. The utility model has the advantages that mechanical connection enables the connection device detachable, convenient to be fast arranged and disassembled on the site and can be repeatedly used. Even the steel bars to be connected are spanning away, the bars can also be connected by lengthening the connection pieces.
Description
Technical field
The utility model relates to a kind of reusable reinforcing steel bar connecting device in the civil construction field.
Background technology
In building trade, usually can run into the reinforcing bar connectivity problem, this sometimes connection is temporary transient, also needs it is thrown off dismounting after using.For example: in the single pile vertical resistance pressure static load test of using anchoring pile crossbeam counterforce device to carry out, in order to make anchoring pile provide needed counter-force to test, reinforcing bar in the anchoring pile need be connected in the energy power transmission on the reinforcing bar of the supporting body on the crossbeam, treat to be the dismounting testing equipment after the off-test, also need this connection is thrown off.
Usually the mode of the similar above-mentioned reinforcing bar of connection that adopts is welding, and it comprises overlap welding and group's bar weldering, but welding manner has following shortcoming: no matter be the sort of welding manner, all need to weld the reinforcing bar of certain-length, workload is big, and the time is long; After using, also must adopt gas cutting or method such as sawed-off to throw off connection, not only increase workload, also can cause the waste of certain material and electric power energy; This connection mostly is field work, and field condition is abominable, the welding quality instability; The arc light that produces in the welding process has sizable injury to human eye, and the naked light of generation also can cause certain disaster hidden-trouble.In addition, welding job is a relatively complicated work post, need be by finishing through the qualified professional technique workman of special training.
Also having a kind of possible connected mode is to be threaded, it at first is processed into screw thread at two end reinforced one section reinforcing bars that desire connects, by threaded branch sleeve in two reinforcing bars are coupled together then, because this method needs in advance reinforcing bar to be processed, and two reinforcing bar required distances strictness to the desire connection, also need during connection reinforcing bar is rotated in the branch sleeve, be difficult to satisfy the engineering that the temporary transient reinforcing bar of needs of this applicable elements that is threaded connects in the reality, adding this being connected still needs to adopt after using gas cutting or method such as sawed-off to make to connect to throw off, connection charge is higher and can not reuse, and this connected mode is used for the engineering reality that the temporary transient reinforcing bar of above-mentioned needs connects and seldom sees.
The utility model content
The purpose of this utility model be propose a kind of simple to operate, quick and convenient and can repeat to use reinforcing steel bar connecting device.
The utility model is to utilize two paired hold assemblies with wedge shape clamping device, and the reinforcing bar that is connected with desire is connected respectively, and is undertaken by one or several connectors that are used to connect two hold assemblies that reinforcing bar connects.When the reinforcing bar pulling force that connects was big more, the hold assembly with wedge shape clamping device was also big more to the chucking power of reinforcing bar, thereby reaches purpose of connecting.Owing to adopt mechanical connection, the utility model linkage is detachable, is convenient to Fast Installation and dismounting at the scene, and can reuses, even between the reinforcing bar that desire connects a segment distance is arranged, also can connect by the method that adopts the lengthening connector.Owing to adopt the wedge shape clamping device, do not need reinforcing bar is carried out extra processing or reinforcing bar does not need extra action.
Description of drawings
Accompanying drawing has been described two embodiment of the present utility model.
Fig. 1 is the structure sectional view of an embodiment.
Fig. 2 is the structure sectional view of another embodiment.
Fig. 3 is a Holding seat stereogram among Fig. 1 and Fig. 2 embodiment.
Fig. 4 is the Holding seat stereogram with pattern of open bore.
The specific embodiment
As shown in Figure 1, the embodiment of this utility model is made up of two pull bars of upper and lower two hold assemblies and two symmetric arrangement, wherein goes up hold assembly and is made up of Holding seat 1a and wedge shape holding piece 2a, and it is used for reinforcing bar 3a in the clamping; Following hold assembly is made up of Holding seat 1b and wedge shape holding piece 2b, and it is used for next root reinforcing bar 3b of clamping; The connector that connects upper and lower two hold assemblies is two pull bars that are respectively 4a and 4b, and it is fixed in up and down on the Holding seat 1a and 1b by nut 5a1,5a2 and 5b1,5b2 respectively.Holding piece 2a has screw thread with the side that 2b contacts with reinforcing bar, and to increase the frictional force between holding piece and the reinforcing bar, it can be some groups of sheets, and according to the size configure of connecting reinforcement diameter.In the nut 5a1, the 5a2 that tighten steady brace 4a and 4b and 5b1,5b2 process, because friction between wedge shape holding piece 2a, 2b and reinforcing bar 3a, the 3b and the wedge effect of wedge shape holding piece 2a, 2b, hold assembly can produce enough big chucking power to reinforcing bar 3a, the 3b that two desires connect up and down; When the reinforcing bar tension after connecting as one was used, based on same mechanism, the suffered pulling force of reinforcing bar was big more, and chucking power is also big more, thereby has reached purpose of connecting.After the reinforcing bar connection is finished using, can remove nut 5a1,5a2 and 5b1, the 5b2 of steady brace 4a and 4b by pine, remove whole reinforcing steel bar connecting device quickly and easily, so that reuse next time.Even between the reinforcing bar that desire connects a segment distance is arranged, also can connect by the method that employing adds long draw 4a and 4b.
As shown in Figure 2, another embodiment of this utility model except with embodiment illustrated in fig. 1 in the pull bar difference that is connected upper and lower two hold assemblies, other and embodiment illustrated in fig. 1 basic identical.Convenience for execute-in-place, anti-screw rod 6a1, the 6a2 of silk and 6b1,6b2 and two screw socket 7a, 7b that are complementary respectively with it form the pull bar of present embodiment connection hold assembly each other by two pairs, only by tighten the screws sleeve 7a, 7b, just upper and lower hold assembly can be coupled together, thereby upper and lower two reinforcing bar 3a, 3b are coupled together.
Figure 3 shows that Holding seat 1a among Fig. 1 and Fig. 2 or the stereogram of 1b.
The foregoing description of the present utility model is not determinate, for example: on-the-spot for convenience the installation, Holding seat can be the pattern that has open bore as shown in Figure 4; The connector quantity that is used to connect two hold assemblies is not limited to two; Connector can adopt multiple connected mode, as the direct screw thread that on the base of hold assembly, is machined for connection, or by direct anti-each other the sheet that is threaded, the sleeve connection hold assembly that utilization has connecting thread on the base of hold assembly, processed; And pull bar can be as the screw rod 6a1 among Fig. 2 only an end have screw thread and with fixed by nut on the hold assembly, the other end can be fixed in by overstriking even be articulated on another hold assembly.
