Embodiment 1

[0139] Use the following method to construct the detachable concrete components, first select and determine the first concrete beam section 1, such as figure 1 , 3 As shown, a plurality of first longitudinal bars 2 and first stirrups 7 are arranged on the upper and lower sides of the first concrete beam section 1 to form a reinforcement cage, and the first section steel 8 is pre-embedded inside the first concrete beam section 1 . One end of the first section steel 8 pre-embedded in the first concrete beam section 1 is provided with a steel plate for anchorage. Among them, it is necessary to ensure accurate component dimensions and accurate longitudinal reinforcement positions during construction, and the reinforcement and cross-sectional dimensions are determined by actual working conditions. The first section steel 8 is required to meet the local shear strength and have a certain degree of safety. The outer dimension B1 of the first stirrup 7 is determined by the first long...

Embodiment 2

[0163] The detachable concrete member made by the construction method in the above-mentioned embodiment 1 has the following structure.

[0164] The detachable concrete member includes a concrete frame column section 5 , a first concrete beam section 1 , a second concrete beam section 3 , and a longitudinal bar intersection area 6 .

[0165] Among them, such as figure 1 As shown, one end of the first concrete beam segment 1 is provided with a male tenon C. The common tenon C includes a tenon C1, an upper tenon shoulder C2 and a lower tenon shoulder C3. The upper tenon shoulder C2 is aligned with the lower tenon shoulder C3 and the tenon C1 is opposite to the upper tenon shoulder. The tenon shoulder C2 and the lower tenon shoulder C3 protrude outwards, and a plurality of first longitudinal ribs 2 are respectively arranged on the upper and lower sides of the first concrete beam section 1, and one end of the first longitudinal ribs 2 runs through the upper tenon shoulder C2 and th...

Embodiment 3

[0172] The detachable concrete member in the embodiment 2 that the construction method in the embodiment 1 is made is carried out relevant performance test, meanwhile, the monolithic concrete member that adopts at present conventionally of the same size is carried out relevant performance test, both relevant performance test results See Table 1. In addition, the detachable concrete components were disassembled and the concrete components after secondary splicing were tested for related performance. The test results are shown in Table 1.

[0173] Table 1 Performance index comparison

[0174]

[0175] It can be seen from Table 1 that the overall flexural bearing capacity and overall shear bearing capacity of the detachable concrete beam of the present invention are similar to those of the monolithic concrete member, and the bearing capacity after disassembly and secondary splicing is still consistent with it. The local shear bearing capacity of the detachable concrete beam o...

Abstract

The invention provides a detachable concrete component. The detachable concrete component comprises a concrete frame column section, a first concrete beam section, a second concrete beam section and a longitudinal bar intersection region, wherein one end of the second concrete beam section is perpendicularly connected with the concrete frame column section integrally; the other end of the second concrete beam section is spliced with a tenon type connecting joint at one end of the first concrete beam section through a mortise type connecting joint; and a plurality of first longitudinal bars arranged on the upper side and the lower side of the inside of the first concrete beam section and a plurality of second longitudinal bars arranged on the upper side and the lower side of the inside of the second concrete beam section outwards extend to the longitudinal bar intersection region and then are connected to one another. The invention further provides a constructing method and application of the detachable concrete component. The manufactured first concrete beam section can be detached and then assembled again, the amount of post-poured concrete is small, the detachable concrete component is convenient to mount and detach, the shearing force bearing capability and the repeated bending moment capability of the detachable concrete component are the same with those of an integrally cast concrete beam, and the structure is safe.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a detachable concrete component construction method, in particular to a detachable concrete beam and a construction method thereof. Background technique [0002] Architecture is the general term for buildings and structures, and it is an artificial environment created by people using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts, and aesthetic principles to meet the needs of social life. At present, the impact of artificial buildings on the environment is becoming more and more significant, especially the building materials used in buildings, which require sustainable utilization and can realize the "3R" concept of "Reduce", "Reuse" and "Recycle". As one of the most used engineering structural materials in construction, concrete is widely used in the construction of houses, water conservancy and municipa...
