Description

0# block construction structure for installing bracket on bent cap

Technical Field

The utility model belongs to the technical field of the technique of bent cap construction and specifically relates to a 0# piece construction structures of installation bracket on bent cap.

Background

At present, the construction scheme aiming at the 0# block of the continuous beam on the bent cap mainly comprises two types: firstly, full supports are erected and fully distributed from the ground to the bottom of the structure, the material period is long, the traffic requirement is high, and the overall height of the structure is low; and secondly, the combination of the steel pipe pile, the I-shaped steel and the like is used, so that the requirement on the bearing capacity of the foundation is high, and calculation is required according to actual conditions.

Therefore, there is a need for a 0# block construction structure for a corbel attachment to a capping beam that can solve the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a 0# piece construction structures of installation bracket on bent cap according to above-mentioned prior art not enough, at the pre-buried hollow steel pipe of bent cap design position, wait after the construction of bent cap prestressing force system, the installation round pin stick, finish rolling screw-thread steel, install the bracket in proper order again, members such as sand box, 0# piece is under construction at last, can effectively solve 0# piece construction problem on the bent cap, a series of problems such as structural height, ground is current, ground bearing capacity requirement are synthesized to the while.

The utility model discloses the purpose is realized accomplishing by following technical scheme:

the utility model provides a 0# piece construction structures of installation bracket on bent cap for the construction of 0# piece, its characterized in that: including the bent cap, pre-buried first hollow steel pipe and the second hollow steel pipe that has set up about relative in the bent cap just the second hollow steel pipe is located first hollow steel pipe top, first hollow steel pipe with install round pin stick and finish rolling deformed steel bar respectively in the second hollow steel pipe, the bracket is all installed just to the bent cap both sides the bracket respectively with the round pin stick with the finish rolling deformed steel bar is connected.

And the sand box, the I-steel and the template system are sequentially placed on the bracket from bottom to top.

The 0# block is placed on the template system.

And two ends of the pin rod extend out of the first hollow steel pipe.

The top of the bracket is connected with the finish rolling deformed steel bar, and the bottom of the bracket is connected with the pin rod.

The utility model has the advantages that: a series of problems such as structural height, ground traffic, foundation bearing capacity requirements and the like can be effectively solved, the design condition of the bracket is obtained through analysis and calculation according to the weight of the 0# block and the condition of the cover beam prestress system, the solution is relatively simple, the construction period is shortened, and the cost is reduced.

Drawings

FIG. 1 is a cross-sectional view of the construction structure of the No. 0 block of the present invention;

fig. 2 is an elevation view of the bent cap of the present invention.

Detailed Description

The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

as shown in FIGS. 1-2, reference numerals 1-10 in the drawings respectively denote a bent cap 1, a first hollow steel pipe 2, a pin 3, a second hollow steel pipe 4, finish-rolled deformed steel bars 5, a corbel 6, a sand box 7, I-shaped steel 8, a formwork system 9 and a # 0 block 10.

Example (b): as shown in fig. 1, the present embodiment relates to a 0# block construction structure for mounting a corbel on a capping beam, which is used for construction of a 0# block 10 and mainly comprises the capping beam 1, the corbel 6, a sand box 7, i-steel 8 and a formwork system 9, wherein a first hollow steel pipe 2 and a second hollow steel pipe 4 which are arranged up and down relatively are embedded in the capping beam 1, and the second hollow steel pipe 4 is located above the first hollow steel pipe 2. The first hollow steel pipe 2 and the second hollow steel pipe 4 are internally provided with a pin 3 and finish-rolled deformed steel bars 5 respectively, and two ends of the pin 3 extend out of the first hollow steel pipe 2. The bracket 6 is arranged on two sides of the bent cap 1, the top of the bracket 6 is connected with the finish-rolled deformed steel bar 5, and the bottom of the bracket 6 is connected with the pin rod 3. As shown in fig. 2, in the present embodiment, the capping beam 1 is a # 60 gate pier capping beam.

As shown in fig. 1, a sand box 7, an i-beam 8 and a pattern plate system 9 are sequentially placed on a bracket 6 from bottom to top, the sand box 7 is used for adjusting the position of the pattern plate system 9, the i-beam 8 is used for supporting the pattern plate system 9, the shape and the size of the pattern plate system 9 are matched with those of a 0# block 10, and the 0# block 10 can be placed on the pattern plate system 9.

As shown in fig. 1, the present embodiment also has the following construction method;
