Description

TECHNICAL FIELD

[0001] The utility model belongs to the construction technology field of steel reinforcement cage, and specifically relates to a positioning auxiliary device for pile foundation steel reinforcement cage installation. BACKGROUND

[0002] Steel reinforcement cage is a kind of building structure material commonly used in building engineering and is widely applied to fields such as foundation engineering, tunnel engineering, bridge engineering and water conservancy engineering. In viaduct bridge engineering, the whole pile foundation steel reinforcement cage is relatively high, and the transportation and installation are very difficult, so generally a plurality of sectional steel reinforcement cages are assembled from bottom to top. The sectional steel reinforcement cage is generally welded and processed in the factory of a building material supplier and then transported to the bridge construction site by vehicles for assembly.

[0003] In order to avoid deformation of the sectional steel reinforcement cage in the transportation process and provide a positioning reference for on-site assembly, the utility model discloses a support for positioning of steel reinforcement cage segments with the publication number CN216765854U. The technical scheme of the patent welds a steel ring-shaped piece on a split support, includes a plurality of positioning pieces matched with the number of longitudinal steel bars of the steel reinforcement cage, the positioning pieces include U-shaped clamps, clamping plates and nuts, the plurality of U-shaped clamps are welded on the steel ring-shaped piece and arranged along the circumference of the steel ring-shaped piece, and then the U-shaped clamps, clamping plates and nuts jointly clamp the longitudinal steel bars on the steel reinforcement cage and the steel ring-shaped piece, so as to realize fixed connection of the steel reinforcement cage and the split support.

[0004] The above-mentioned prior art has the following defects:

[0005] (1) The clamping plate of the positioning piece is pre-welded on the steel ring-shaped piece, which puts high requirements on the hoisting and positioning of the steel reinforcement cage, and it is difficult to align the longitudinal steel bars on the steel reinforcement cage with the corresponding clamping plates of the positioning pieces.

[0006] (2) The positioning piece includes a U-shaped clamp, a clamping plate and at least two nuts. After the positioning piece is disassembled, the nut and the U-shaped clamp are in a completely separated state, which means that the nut needs to be completely unscrewed from the U-shaped clamp when the positioning piece is disassembled. Since the number of positioning pieces is large, the work of unscrewing the nuts is very large. In addition, the nut is relatively small in size and is prone to falling during unscrewing. High-altitude assembly is prone to high-altitude falling of nuts. UTILITY MODEL CONTENTS

[0007] The technical problem to be solved by the utility model is to make up for the deficiencies of the prior art and provide a positioning auxiliary device for pile foundation steel reinforcement cage installation.

[0008] To solve the above technical problems, the technical scheme of the utility model is as follows:

[0009] A positioning auxiliary device for installing a pile foundation reinforcement cage includes two half brackets and several main reinforcement fixing units. The half brackets include an integrally connected U-shaped frame body and a semi-circular arc plate; the two half brackets are arranged opposite to each other and are detachably fixed to form a rectangular frame. The semi-circular arc plates of the two half brackets are concentric and an adjustment slot is provided on the semi-circular arc plate; the main reinforcement fixing unit includes a fixing block A and a fixing block B. The fixing block A includes an integrally connected U-shaped rod and a connecting plate. The U-shaped rod includes an arc portion and a guide rod. The connecting plate is provided with a U-shaped through groove. The through direction of the U-shaped through groove is consistent with that of the semi-circular arc plate. The length directions of the guide rods are parallel to each other; the fixing block B includes a fixing plate, both ends of which are hinged with screws, the rotation direction of the screws is adapted to the U-shaped through slot, a nut B is screwed on the screw, two guide holes are provided on the fixing plate, and a wing plate is provided on the fixing plate; the fixing plate of the fixing block B is placed in the adjustment gap on the semicircular plate, and the wing plate is located on the convex surface of the semicircular plate; the fixing block A is located on the concave surface of the semicircular plate, the guide rod of the U-shaped rod is inserted into the guide hole, the screw passes through the U-shaped through slot, and the nut B is tightened so that the arc part and the fixing plate clamp the main reinforcement of the steel cage.

[0010] Furthermore, the U-shaped frame body of the half bracket is formed by welding steel profiles.

[0011] Furthermore, a plurality of fixing holes are provided at the connection opening of the U-shaped frame body of the half bracket; the two half brackets are half bracket I and half bracket II, and the screws pass through the fixing holes and nuts A of half bracket I and half bracket II in turn, and are screwed with nuts A, thereby fixing half bracket I and half bracket II in connection.

[0012] Furthermore, the width of the semicircular arc plate is smaller than the distance between two adjacent stirrups of the steel cage.

[0013] The beneficial effects that can be achieved by the utility model are:

[0014] (1) By matching the fixing block B with the adjustment seam on the semicircular plate, the main reinforcement fixing unit can be accurately installed at the cross intersection of the main reinforcement and the adjustment seam of the steel cage. This greatly reduces the position accuracy requirements for the hoisting and positioning of the steel cage, making it easier for construction workers to operate.

[0015] (2) For the main reinforcement fixing unit, the nut B, which plays the role of fixing and splitting, is always screwed to the screw by the rotation of the screw rod into and out of the U-shaped groove. During the operation, there is no need to completely screw the nut B to disengage from the screw rod. This not only reduces the workload of screwing the nut, but also effectively avoids the nut falling from a high altitude, thereby improving the construction safety factor.
