The utility model discloses an adopt and set up fixture and come the vertical reinforcing bar of accurate positioning in the template inboard, can ensure simultaneously that protective layer thickness is even, and then guaranteed that steel reinforcement cage skeleton position is accurate, and protective layer thickness is up to standard, has improved the construction quality and the construction progress of cast-in-place roof beam. And the utility model discloses simple structure, convenient to use, it is with low costs.
Description
Technical Field
The utility model relates to a construction technical field, especially a fixture for vertical reinforcing bar location of cast-in-place roof beam.
Background
With the vigorous development of subway construction industry in China, the construction of crown beams and reinforced concrete supporting beams is more and more common, and the construction requirements are higher and higher. In the work progress, need guarantee on the one hand that steel reinforcement cage skeleton position is accurate, on the other hand still needs to guarantee that the protective layer thickness is up to standard. It is also very important to ensure the convenience of the operation of the operator. In the construction process, once the position of the vertical steel bar is inaccurate, the position of the whole steel bar framework is directly influenced, and the stress of the whole envelope structure is influenced, so that the difference between the actual stress and the design stress of the structure is large, and the safety risk is brought to the engineering; on the other hand, the thickness of the protective layer may be uneven, which may cause unnecessary trouble in the process.
How to ensure accurate positioning of vertical steel bars of a crown beam and a reinforced concrete supporting beam in construction and convenient operation is a key node for cast-in-place beam construction. The conventional method for positioning the vertical reinforcing steel bar of the cast-in-place beam has poor accuracy and cannot ensure the uniform thickness of a protective layer, so the economic benefit and the social benefit of the conventional method are not obvious.
Disclosure of Invention
The utility model discloses a solve the technical problem who exists among the well-known technology and provide a fixture for cast-in-place roof beam vertical reinforcement location, this fixture can make vertical reinforcement location accurate, protective layer thickness even.
The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: a fixture for positioning vertical steel bars of a cast-in-place beam comprises main bars which are equal to the cast-in-place beam in length and adaptive to the cast-in-place beam in shape, wherein a plurality of positioning steel bars which are parallel to each other are vertically welded on the main bars, the positioning steel bars stretch across the main bars, vertical bar positioning bayonets are arranged on the inner sides of the main bars, the widths of the vertical bar positioning bayonets are equal to the diameters of the vertical steel bars, the vertical bar positioning bayonets are formed by two adjacent positioning steel bars, and the distance between the two adjacent vertical bar positioning bayonets is the designed interval of the vertical steel bars; the distance between the outer end of the positioning steel bar and the inner side of the main bar is equal to the thickness of the protective layer.
The utility model has the advantages and positive effects that: through adopting and setting up fixture in the template inboard and come the accurate positioning vertical reinforcing bar, can ensure simultaneously that protective layer thickness is even, and then guaranteed that the steel reinforcement cage skeleton position is accurate, protective layer thickness is up to standard, has improved the construction quality and the construction progress of cast-in-place roof beam. And the utility model discloses simple structure, convenient to use, usable waste material reinforcing bar preparation, circulated use, it is with low costs.
Drawings
FIG. 1 is a partial schematic view of the present invention;
fig. 2 is a partial enlarged view of the present invention.
In the figure: 1. a main rib; 2. positioning the reinforcing steel bars; 3. vertical reinforcing steel bars; 4. and (5) template.
Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:
referring to fig. 1 and 2, a fixture for positioning vertical steel bars of a cast-in-place beam comprises a main bar 1 which is equal to the cast-in-place beam in pouring length and adaptive to the cast-in-place beam in shape, wherein a plurality of parallel positioning steel bars 2 are vertically welded on the main bar 1, the positioning steel bars 2 cross over the main bar 1, vertical bar positioning bayonets are arranged on the inner side of the main bar 1, the width of each vertical bar positioning bayonet is equal to the diameter of a vertical steel bar 3, each vertical bar positioning bayonet is formed by two adjacent positioning steel bars 2, and the distance between the two adjacent vertical bar positioning bayonets is the designed vertical steel bar distance; the distance between the outer end of the positioning steel bar 2 and the inner side of the main bar 1 is equal to the thickness of the protective layer.
In the construction process of the cast-in-place beam, firstly, a formwork 4 is erected, after the formwork 4 is firmly supported, the fixture is installed in the firmly supported formwork 4, the upper part and the lower part of the fixture are respectively set, and the accurate and vertical position of the vertically positioned reinforcing steel bar is ensured according to the principle that two points determine a line. When the fixture is installed, the two ends of the main reinforcement 1 and the outer end of the positioning reinforcement 2 are respectively tightly propped against the template 4. And then binding the reinforcing steel bars, temporarily fixing bayonets at two ends and the vertical reinforcing steel bars 3 in the bayonets at two ends for construction convenience, adopting a binding or spot welding method, then sequentially putting the vertical reinforcing steel bars 3 into the positioning bayonets, and enabling the clamping apparatus to play a role in accurate positioning. And after the steel bars are completely bound or after the concrete pouring height can ensure that the steel bar framework is stable, the fixture is disassembled and recovered for the next reuse.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
