Description

Prefabricated ring roof beam for building convenient to fixed connection

Technical Field

The utility model relates to a building field, concretely relates to prefabricated circle roof beam for building convenient to fixed connection.

Background

The ring beam is a continuous closed beam arranged along the periphery of the outer wall of the building and part of the inner transverse wall. Its purpose is in order to strengthen the overall rigidity of building and the stability of wall body. The existing ring beam is formed by cast-in-place of reinforced concrete, and the ring beam made of the reinforced steel bars and the concrete fully utilizes the reinforced steel bars to bear tension and the concrete to bear pressure. Has the advantages of firmness, durability, good fireproof performance and the like.

However, when the prefabricated building structure system is used in the upper portion of the ring beam, since the prefabricated building structure is relatively simple and the volume is relatively small, and when the reinforced concrete structure is used in the ring beam, the reinforced concrete structure itself has the following disadvantages, (1) self-weight. The gravity density of the reinforced concrete is about 25kN/m ^3, which is heavier than the weights of the masonry and the wood. Although less heavy than steel, the cross-sectional dimensions of the structure are large, and thus its own weight far exceeds the weight of a steel structure of the same span or height. (2) The crack resistance is poor. As described above, the tensile strength of concrete is very low, and thus, a general reinforced concrete structure often works with cracks. Although the presence of cracks does not necessarily mean that the structure is damaged, it affects the durability and aesthetics of the structure. When the number of cracks is large and the width of the cracks is wide, an unsafe feeling is also brought to people. (3) The quality is brittle. The brittleness of the concrete is increased along with the improvement of the strength grade of the concrete, and the like. Based on this, a utility model patent with application number 201820272925.5 named as a precast ring beam was designed by those skilled in the art. The application of the technology disclosed by the patent in the building process discovers that only a threaded rod is penetrated between an inner folding edge and an outer folding edge in the prefabrication process, and the threaded pipe cannot keep the stability between the inner folding edge and the outer folding edge, so that the prefabricated ring beam for the building, which can keep the stability between the inner folding edge and the outer folding edge and is convenient for fixed connection, is designed to meet the urgent requirement.

Detailed Description

In order to make the technical solution and the beneficial effects of the present invention clearer, the following is a further detailed explanation of the embodiments of the present invention.

Example one

The utility model provides a prefabricated ring roof beam for building convenient to fixed connection, includes bar-shaped component, corner component, connects through the corner component between the bar-shaped component, and the bar-shaped component uses stirrup and twisted steel to form as skeleton concreting, and the stirrup is the rectangle structure, and four twisted steel set up on four interior angles of a plurality of even stirrups of interval, have the unequal screw thread of 20MM to 50MM at twisted steel's port, and wherein twisted steel quantity, interval, combination situation are calculated by the atress and come. The screw thread of the twisted steel end of the bar-shaped member extends and then is positioned outside the concrete, so that the bar-shaped member can be conveniently connected with the corner member through the corner member.
