Underground garage structure form capable of increasing installation height of equipment pipeline

Abstract

The utility model relates to the field of constructional engineering, in particular to design and construction of an underground garage roof structure form. The technical problem to be solved by the utility model is to provide an underground garage roof structure form in the field of constructional engineering so as to improve the installation height of garage equipment pipelines and improve the space sense of a garage. In order to solve the problem, the solution provided by the utility model comprises the following steps: increasing the beam height of the underground garage, forming a hole in the beam to form an open-web truss, and carrying out structural calculation design on the open-web truss according to the open-web truss; the equipment pipeline penetrates through the beam and is installed at the beam opening position, the installation height of the equipment pipeline is increased, and the equipment pipeline is hidden between the beam grids. When a structural beam is constructed, a formwork is installed firstly, then lower chord and web member steel bars are bound, then a hole formwork is installed, and finally concrete is poured after upper steel bars are bound; after the formwork is removed according to construction requirements, the pipeline can be subjected to beam-penetrating installation construction.

Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to the design and construction of a roof structure of an underground garage. Background Art

[0002] In the field of construction engineering, when it comes to the design and construction of the underground garage roof structure, due to the large loads of soil, greening and fire trucks above the garage roof, the garage beam cross-section is large, and the installation of equipment and pipelines is limited by the beam height. They are usually installed below the bottom of the beam, resulting in a low equipment elevation and insufficient sense of garage space. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a roof structure of an underground garage in the field of construction engineering, so as to increase the installation height of garage equipment pipelines and enhance the sense of garage space.

[0004] To solve the above problems, the solution provided by the present invention includes:

[0005] Increase the height of the underground garage beams, open holes in the beams, form hollow trusses, and perform structural calculation and design based on hollow trusses;

[0006] The equipment pipeline is passed through the beam and installed at the opening of the beam, which increases the installation height of the equipment pipeline and hides the equipment pipeline between the beam grids. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In the design and construction of the roof structure of underground garages in the field of construction engineering, the height of the garage beam is increased, and the equipment pipelines are installed through the beam openings, so that the installation height of the equipment pipelines is closer to the bottom of the floor slab; the structural design calculation model after the beam opening is considered as a hollow truss, and the size and reinforcement are determined according to the structural calculation. When constructing the structural beam, the template is installed first, then the lower chord and web reinforcement are tied, and then the opening template is installed, and finally the upper reinforcement is tied and concrete is poured; after the template is removed according to the construction requirements, the pipeline can be installed through the beam.

Claims

1. An underground garage structure for increasing the installation height of equipment pipelines, relating to the field of construction engineering, and in particular to the design and construction of the roof structure of an underground garage, characterized by: By increasing the height of the garage beams and opening holes in the beams to form a hollow truss, the structural calculation and design are performed on it according to the hollow truss. The equipment pipes pass through the beams and are installed at the beam openings, which increases the installation height of the equipment pipes.
