Background
At present, a subway station or a shield well is a necessary condition for starting and receiving of a shield machine, a reinforced concrete pile wall body on the inner side of an end well enclosure structure of a tunnel portal needs to be broken before the starting, arrival and crossing of the shield machine, a large construction safety risk exists in the breaking process, the construction period is long, if an outer stratum after the breaking is directly exposed, water burst and collapse are easy to occur, surrounding strata are settled, even collapse is caused, and the shield machine cannot be normally started and received.
The glass fiber reinforced plastic is GFRP, is a glass fiber reinforced composite material, is made up by using glass fiber and resin through the processes of hot-melting and can be made into the form and size identical to that of reinforcing bar. Compared with steel bars, GFRP bars have the advantages of high tensile strength, light weight, good cuttability, good corrosion resistance, low heat and electric conductivity and the like, and can be used for replacing common steel bars in many cases. The shield can directly cut the pile wall body when starting, and soil pressure is built, so that the shield can safely start construction under the condition of reinforcing a small amount of end heads and not lowering water.
There are some problems after applying the glass fiber reinforcement to partially replace the reinforcing steel bar, such as: how to connect the glass fiber reinforcements and how to connect the glass fiber reinforcements with the reinforcing steel bars, if the connection is not firm, accidents such as collapse of a pile wall body and the like easily occur in the end well construction process and the shield tunneling process, and therefore the connection must be firm. However, the glass fiber reinforced plastic is formed at a high temperature, has no welding property, and is difficult to bend, so that a mechanical method is considered for the connection.
In the prior art, the lapping part of the glass fiber rib and the steel bar of the enclosure structure generally adopts a binding type connection method, and a U-shaped buckle is adopted for bidirectional fastening connection, as shown in fig. 1 and fig. 2, the U-shaped buckle generally comprises a U-shaped bolt 1, a pressing plate 2, a nut 3 and a gasket 4, the pressing plate 2 is provided with two through holes 5, when in use, the glass fiber rib 6 and the steel bar 7 are both arranged along the front-back direction, the glass fiber rib 6 and the steel bar 7 are lapped left and right, the U-shaped bolt 1 is sleeved on the lapping part of the glass fiber rib 6 and the steel bar 7 along the left and right direction, then the pressing plate 2 is sleeved on two arms of the U-shaped bolt 1 through the two through holes 5, and then the gasket 4 and the nut 3 are respectively sleeved on the two arms of the U.
However, the U-shaped buckle is adopted for bidirectional fastening connection, and the following disadvantages are present:
1. the contact area between the U-shaped bolt and the glass fiber reinforced bars and the common steel bars is too small, and the friction force is insufficient;
2. the double bolts are fastened, one end is fastened first, and the other end is fastened, so that the bolts are easy to loosen;
3. one more movable point is provided, and the other more movable point is provided, and the through hole of the pressure plate is in a transverse groove type, so that the possibility of loosening is increased;
4. the quantity is large, generally one lap joint is required to be provided with three lap joints, and materials are wasted.
Therefore, the fixed appearance of this kind of structure is circular shape glass fiber muscle and reinforcing bar, and area of contact undersize is not hard up easily, and every lapped position will arrange threely moreover, and not only construction quality is difficult for guaranteeing, extravagant material moreover.
Therefore, it is desirable to provide a glass fiber reinforced plastic bar buckle, which not only can fix the glass fiber reinforced plastic bar and the steel bar lap joint part, but also is firm in fixation, ensures the construction quality and saves materials.
