Description

Double-layer hanging piece structure for positioning UHPC upright post main reinforcement steel bars

Technical Field

The utility model relates to a bridge prefabrication construction technical field especially relates to a double-deck formula lacing film structure for UHPC stand owner muscle reinforcing bar location.

Background

With the green rapid construction, bridge prefabricated parts are used more and more frequently in the bridge field for construction, for example: prefabricated stand, prefabricated case roof beam etc.. For an Ultra High Performance Concrete (UHPC) upright column, a sectional prefabrication method is often adopted for construction, that is, the Ultra High Performance Concrete (UHPC) upright column is divided into a plurality of sections in the height direction of the upright column for prefabrication, and then the prefabricated sections are spliced and fixed to form a whole. At present, when a UHPC stand column is prefabricated, the binding of main reinforcing steel bars generally can only be performed through one-by-one manual binding construction, the time consumption is long, the efficiency is low, and the more serious problem is that the position precision of the main reinforcing steel bars cannot be ensured, so that the position of the main reinforcing steel bars is greatly different from the design requirement, and even the quality of the prefabricated UHPC stand column is not in line with the requirement.

Disclosure of Invention

The utility model aims at providing a double-deck formula lacing film structure for UHPC stand owner muscle reinforcing bar location according to above-mentioned prior art not enough, realize the quick accurate positioning of UHPC owner muscle reinforcing bar through the inside and outside layer location lacing film of double-deck formula components of a whole that can function independently.

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

the utility model provides a two-layer equation lacing film structure that is used for UHPC stand owner muscle reinforcing bar to fix a position which characterized in that: the outer hanging pieces and the inner hanging pieces are respectively provided with a positioning hook part which is used for being matched with a main reinforcing steel bar of the UHPC stand column.

The positioning hook part is arranged on the outer side of the outer layer hanging piece and the outer side of the inner layer hanging piece.

The two outer hanging pieces are positioned on two sides of the two inner hanging pieces and are arranged vertically, and the two inner hanging pieces are arranged horizontally and vertically.

The positioning hook parts of the two outer layer hanging pieces and the positioning hook parts of the inner layer hanging pieces positioned below the two outer layer hanging pieces are arranged upwards.

And the outer-layer hanging piece and the inner-layer hanging piece are both connected and fixed with the UHPC upright post mould.

The utility model has the advantages that: the high-precision and quick positioning of the UHPC upright post main reinforcement steel bar can be realized, and the position precision of the UHPC upright post main reinforcement steel bar is ensured to meet the design requirement; simple and reasonable structure and convenient installation.

Drawings

Fig. 1 is a schematic structural diagram 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 fig. 1, the symbols 1-5 in the figure are respectively expressed as: the hanging piece comprises an outer layer hanging piece 1, an inner layer hanging piece 2, a positioning hook part 3, a mould 4 and a main reinforcing steel bar 5.

Example (b): as shown in fig. 1, the double-layer hanger plate structure for positioning main reinforcing steel bars of the UHPC column in this embodiment is used in a prefabrication process of the UHPC column, and the UHPC column is placed in a horizontal direction during prefabrication, so that the main reinforcing steel bars extend in the horizontal direction, and the main reinforcing steel bars 5 are effectively and precisely positioned and supported by the split double-layer hanger plate structure, so that the position accuracy of the split double-layer hanger plate structure is ensured to meet design requirements.

Specifically, as shown in fig. 1, the double-layer hanging piece structure comprises two outer hanging pieces 1 and two inner hanging pieces 2 which are arranged in the same section of the UHPC stand column, wherein the double-layer structure means that the two outer hanging pieces 1 are positioned at the periphery of the two inner hanging pieces 2 to form an inner structure and an outer structure, and the two hanging pieces are both single-piece split structures, so that the double-layer hanging pieces are mutually kept away and do not interfere with each other. The outer layer hanging piece 1 is vertically arranged and comprises a left hanging piece and a right hanging piece along the direction of figure 1; the inner layer hanging piece 2 is arranged horizontally and comprises an upper hanging piece and a lower hanging piece along the direction of figure 1. The shape formed by the outer layer hanging piece 1 and the inner layer hanging piece 2 is matched with the cross section shape of the UHPC upright post.

As shown in fig. 1, the outer sides of the outer layer hanging pieces 1 at two sides are respectively provided with a plurality of positioning hook parts 3 which are arranged at intervals, and the number and the spacing of the positioning hook parts 3 are correspondingly arranged according to the design position of the UHPC upright post main reinforcement steel bar. The positioning hook part 3 is a hook body which is bent upwards, the shape and the size of the hook body are matched with the shape and the size of the outer contour of the main reinforcing steel bar 5, and the main reinforcing steel bar 5 can be directly clamped in the positioning hook part 3, so that the positioning hook part 3 can effectively position and support the main reinforcing steel bar 5.

As shown in fig. 1, the bottom of the lower inner layer hanger plate 2 is also provided with a positioning hook 3 which is bent upwards, the positioning hook 3 of the upper inner layer hanger plate 2 is annular, and the main reinforcement steel bar 5 can pass through the ring to realize effective positioning and supporting.

In the embodiment, in specific implementation: outer lacing film 1 and inlayer lacing film 2 all are connected fixedly with the mould 4 that is used for prefabricating UHPC stand to guarantee the supporting effect to main muscle reinforcing bar 5.

Auxiliary fixing parts can be arranged at the positioning hook parts 3 of the outer hanging piece 1 and the inner hanging piece 2 so as to connect and fix the main reinforcing steel bars 5 and the corresponding positioning hook parts 3, and the positioning and supporting effects are further improved.

Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims.
