Abstract
A cast-in-place structure of a high pier bent cap without a support is used for realizing cast-in-place construction of the bent cap without the support, effectively improving the efficiency and the construction safety of the bent cap and being beneficial to saving cost. The bridge pier comprises a stiff framework participating in stress of a bent cap structure, wherein the stiff framework is connected with an embedded steel column at the top of the bridge pier in a welding manner; distribution beams fixedly installed by steel pull rods are arranged below the stiff skeleton at intervals, and template systems are installed on the distribution beams.
Description
Technical Field
The utility model relates to a civil construction engineering, the cast-in-place construction structures of specially adapted high pier bent cap.
Background
The conventional construction method of the ordinary pier capping beam is that the cast-in-place is carried out after an external support is erected, when the pier is high, safety risks such as instability and deformation exist, and the erection of a support system is high in investment cost and long in turnover time; and the storage and maintenance management of the external support system requires both site and labor. In order to reduce the use of external temporary supports, improve construction safety, save cost and improve work efficiency, a high pier capping beam support-free cast-in-place structure needs to be developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a high pier bent cap does not have cast-in-place structure of support is provided to realize the cast-in-place construction of bent cap no support, effectively improve bent cap efficiency and construction security, and be favorable to practicing thrift the cost.
The utility model provides a technical scheme as follows that above-mentioned technical problem took:
the utility model discloses a cast-in-place structure of high pier bent cap no support, characterized by: the bridge pier comprises a stiff framework participating in stress of a bent cap structure, wherein the stiff framework is connected with an embedded steel column at the top of the bridge pier in a welding manner; distribution beams fixedly installed by steel pull rods are arranged below the stiff skeleton at intervals, and template systems are installed on the distribution beams.
The utility model has the advantages that the stiff frameworks participating in the stress of the bent cap structure are welded and fixed on the top of the pier, and the stiff frameworks are used as the supporting bodies of the template system, so that the cast-in-place construction of the bent cap without the support is realized; the stiff skeleton structure can be installed by a tower crane system, so that the capping efficiency and the construction safety can be effectively improved, and the cost can be saved.
Drawings
The specification includes the following two figures:
FIG. 1 is a cross bridge vertical view of a high pier capping beam non-support cast-in-place structure of the present invention;
FIG. 2 is a cross-sectional view of a high pier bent cap support-free cast-in-place structure of the present invention;
the figures show the components and corresponding references: the steel structure comprises piers 10, embedded steel columns 11, a stiff skeleton 20, steel pull rods 21, transverse distribution beams 22, longitudinal distribution beams 23 and a template system 30.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 and 2, the utility model discloses a cast-in-place structure of high pier bent cap no support, including a strength nature skeleton 20 of participating in the bent cap structure atress, this strength nature skeleton 20 and the pre-buried steel column 11 welded connection at pier 10 top. Distribution beams fixedly installed by steel pull rods 21 are arranged below the stiff frameworks 20 at intervals, and template systems 30 are installed on the distribution beams.
Referring to fig. 1, a stiff skeleton 20 calculates the stiffness and the structural dimension according to the dead weight of a capping beam, and conventional section steels (such as i-beams, channel steels and angle steels) are adopted to assemble chords, diagonal web members, vertical bars, flat link rods and the like of an inner support system, and the stiff skeleton is welded and connected with embedded steel columns 11 at the top of a pier 10 to serve as a support body of a template system, so that the cast-in-place construction without a support of the capping beam is realized. The stiff skeleton 20 can be installed by a tower crane or a cable hoisting system, and the template system 30 comprises a bottom die and a side die which are installed on the distribution beam, so that the stiff skeleton structure is uniformly stressed when the capping beam is poured with concrete, the capping beam efficiency and the construction safety can be effectively improved, and the cost is saved.
Referring to fig. 1 and 2, the distribution beam includes transverse distribution beams 22 arranged at intervals in the transverse bridge direction and longitudinal distribution beams 23 arranged at intervals in the longitudinal bridge direction, the lower end of the steel tie rod 21 is connected to the intersection of the transverse distribution beams 22 and the longitudinal distribution beams 23, and the upper end is connected to the top of the stiff skeleton 20.
The above is only used for illustrating the present invention, and the present invention is not limited to the specific structure and application range shown and described, so all the corresponding modifications and equivalents that may be utilized all belong to the patent scope applied by the present invention.
