Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a special simple cushion block suitable for a pier column reinforcement cage. Background Art

[0002] The pier is an important structure in bridge engineering. It supports the cap beam from top to bottom and acts on the tie beam and pile foundation. Usually, when constructing the pier, it is necessary to first dig the tie beam foundation pit, break the pile foundation head, pour the tie beam cushion layer, and then install the pile foundation, column and tie beam reinforcement together, put on the tie beam formwork for pouring, and after the concrete is completely solidified, remove the tie beam formwork, backfill the foundation pit, and then put on the pier formwork to pour the pier concrete, and finally remove the formwork for maintenance. During normal operation, the upper bridge deck is subjected to force, which is transmitted to the box beam, and then to the cap beam, and then distributed to the pier, and the pier is distributed downward to the abutment or tie beam, until the pile foundation. Therefore, the pier is basically standing on the ground and is an exposed structure. The protective layer of the pier is easily damaged, resulting in work efficiency.

[0003] Therefore, it is necessary to provide a special simple pad suitable for pier column reinforcement cage to solve the above technical problems. Utility Model Content

[0004] The utility model provides a special simple cushion block suitable for a pier column reinforcement cage, which solves the technical problem of the above background.

[0005] In order to solve the above technical problems, the utility model provides a special simple pad suitable for pier column reinforcement cage, including two pads, a template and spiral reinforcement, a connecting block is fixed between the two pads, and a convex block is fixed on the connecting block;

[0006] A concrete block is arranged between the two pads, two openings are arranged on the pad, and a groove is arranged at the bottom of the pad. A first fixing groove and a second fixing groove are respectively arranged on the pad, and an iron wire runs through the opening.

[0007] Preferably, the concrete block is made of concrete.

[0008] Preferably, the concrete blocks and pads are both crescent-shaped.

[0009] Preferably, the surface of the concrete block is in contact with the inner wall of the formwork.

[0010] Preferably, the spiral rib is in contact with the groove of the cushion block, and the spiral rib is tied and fixed to the cushion block by iron wire.

[0011] Preferably, the first fixing groove and the second fixing groove are adapted to the iron wire.

[0012] Compared with the related art, the simple pad block suitable for pier column reinforcement cage provided by the utility model has the following beneficial effects:

[0013] The utility model provides a special simple pad block suitable for the steel bar cage of pier column. The concrete blocks on the pad block are in contact with the inner wall of the template through the surrounding of the steel bar cage. The supporting strength of the concrete block is improved through the convex blocks on the connecting block, so as to provide supporting protection. The utility model has a simple structure and is convenient to construct. Compared with the traditional plum blossom shaped pad block, the crescent shape thereof changes from small to large by rotating, so it is easier to pad the steel bar cage after the template is installed. Holes are opened on both sides of the pad block, so that the middle part is less likely to be broken when squeezed by the template and spiral reinforcement. The outermost edge is arc-shaped, so as to ensure that only one point is in contact with the column template. After sufficient vibration, it can be effectively controlled that no pad block traces appear on the surface of the poured column structure, and the problem that the column protective layer is difficult to control can be basically solved.

[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0019] Please refer to Figure 1-3 As shown, a simple pad suitable for pier column reinforcement cage includes two pads 1, a template 2 and a spiral reinforcement 3. A connecting block 4 is fixed between the two pads 1, and a protrusion 5 is fixed on the connecting block 4. The protrusion 5 on the connecting block 4 improves the supporting strength of the concrete block 6;

[0020] A concrete block 6 is arranged between two cushion blocks 1 of the utility model, two openings 7 are arranged on the cushion block 1, and a groove 8 is arranged at the bottom of the cushion block 1, and a first fixing groove 9 and a second fixing groove 10 are respectively arranged on the cushion block 1, and an iron wire 11 is passed through the opening 7, and the first fixing groove 9 and the second fixing groove 10 are adapted to the iron wire 11;

[0021] The concrete block 6 of the utility model is made of concrete. The concrete block 6 and the cushion block 1 are both crescent-shaped. The surface of the concrete block 6 contacts the inner wall of the template 2. The crescent shape of the cushion block 1 changes from small to large and is easier to be placed on the steel cage after the template 2 is installed. Holes are opened on both sides of the cushion block. The middle part is less likely to break when squeezed by the template 2 and the spiral reinforcement 3. The outermost edge is arc-shaped to ensure that only one point contacts the template 2.

[0022] The spiral rib 3 of the utility model contacts the groove 8 of the cushion block 1, and the spiral rib 3 is tied and fixed to the cushion block 1 by the iron wire 11, so as to facilitate installation and fixing.

[0023] The working principle of the simple pad block specially used for the pier column reinforcement cage provided by the utility model is as follows: the iron wire 11 passes through the opening 7 on the pad block 1 and is tied to the spiral reinforcement 3 of the reinforcement cage. After the template 2 is molded, the column protective layer is checked in the template 2, and the pad block 1 is inserted in the place where the protective layer is smaller, so that the reinforcement cage is in contact with the inner wall of the template 2 through the concrete block 6 on the pad block 1. The supporting strength of the concrete block 6 is increased through the protrusion 5 on the connecting block 4, and support protection is performed. After the inspection is completed and the protective layer is all qualified, concrete pouring is performed. The pad block 1 does not need to be removed and is not recycled and reused.

[0024] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
