Description

預鑄 joint and its beam-column structure

This creation is related to construction technology, especially a type of joint and its beam-column structure used for the joint structure of steel bars and steel frames.

The seismic strength of residential buildings is mainly determined by the reinforced concrete wall plate and column beam steel structure. However, the commonly used reinforced concrete (RC) structure nowadays is difficult to test its earthquake resistance because the reinforced concrete structure will be covered by concrete. strength. It can be seen from this that, in practice, it is difficult for consumers to ensure the safety and seismic quality of the buildings they live in.

In addition, the traditional reinforced concrete structure is relatively rigid and has a heavier weight. When applied to a high-rise building, when the load is accumulated in layers, thicker beams and columns are required to support the overall building, which is not easy to construct. It also leads to a reduction in the available indoor space, so the number of floors covered by a building usually only made of reinforced concrete structures will not exceed 30. Therefore, in order to improve its shortcomings, the department has developed steel-reinforced concrete (SRC) structures or steel-reinforced (SC) structures suitable for high-rise buildings. In residential buildings, steel-reinforced concrete (SRC) structures or steel-reinforced concrete (SC) structures have been developed. The soil structure is the most popular.

The steel-reinforced concrete structure combines the structural form of steel-reinforced concrete and steel-reinforced concrete. The outer layer of the steel-reinforced concrete is additionally equipped with steel bars and grouted to form a protective layer. Therefore, it has the characteristics of two structures at the same time. The need to thicken the column can increase the strength of the column, and the structural characteristics of reinforced concrete can reduce the problem of excessive deformation when the pure steel structure is subjected to lateral force, and can reduce the degree of shaking when an earthquake comes.

Although the steel-reinforced reinforced concrete structure can effectively improve the problems of the reinforced concrete structure, in terms of construction, it greatly increases the cost of materials, labor and construction time.

Therefore, the current technology can improve the problems of the traditional reinforced concrete structure, and can also solve the technology that increases the cost of materials, labor and construction time for the steel reinforced concrete structure, thereby improving the problems existing in the prior art.

As shown in FIG. 2, when the above-mentioned joint 100 is installed on the beam-column structure 200, since the beam-column structure 200 is composed of at least a plurality of main steel bars 20 and a plurality of stirrups 23, it is worth noting However, for the commonly known reinforced concrete, in addition to the arrangement of the main steel bars 20 and stirrups 23, it should also have a plurality of tie bars 24 arranged on the main steel bars. However, due to the arrangement of the tie bars 24 The setting of is a conventional technology, and the focus of creation in this creation does not change the structure of the tie bars 24 or the connection relationship, so the description of the tie bars 24 is omitted here. The main steel bars 20 are individually arranged at regular or irregular intervals to form the frame-shaped beam-column structure 200, and the stirrups 23 are connected to each other at intervals (also regularly or irregularly) On the beam-column structure 200, the frame-shaped structure of the beam-column structure 200 is further fixed.

In this way, when the ray joint 100 is installed on the beam-column structure 200, the ray joint 100 can usually be installed on the beam-column structure in order to set up beams or connect the beam-column structures 200. The middle section of 200 or the position adjacent to the middle section, and of course, this is not limiting the location of the fascia joint 100, but only when the fascia joint 100 is installed on the beam-column structure 200, all It should belong to the scope of the patent to be protected by this creation. The connecting section 10 included in the connecting section 100 will provide the main reinforcing bars 20 through the through portions 101 included therein, and further, to strengthen the connecting section 10 and the beams and columns. The strength of the connection between the structures 200, the web 103 of the connecting section 10 may also be provided with a plurality of web holes 1031 (as shown in FIG. The stirrups 23 are penetrated and connected, so that when the connecting section 10 is connected to the beam-column structure 200 and is located inside the beam-column structure 200, the first extension section 11 and the second extension connected to the connecting section 10 The section 12 extends outward from the inner position of the beam-column structure 200, that is, the first extension section 11 extends outward from a surface of the beam-column structure 200, and the second extension section 12 extends from and from the first extension section. One side of the beam-column structure 200 with a different extension section 11 extends outward.

In addition to the beam-column structure 200 itself, the beam-column structure 200 may also include the first joint section 21 and the first joint section 21 for joining another beam-column structure 200, for forming a beam, or other related purposes. The two joint sections 22, the first joint section 21 and the second joint section 22 can also be formed by the main steel bars 20, the stirrups 23 and even the tie bars 24. However, here are the different joint sections ( 21, 22) and the beam-column structure 200, so the description of the joining section is mainly based on the structural relationship or the connection relationship set thereon.

The first joining section 21 is fastened to the first positioning bodies 111 provided on the first extension section 11 through the first fixing portions 211, so that the first joining section 21 can be stably connected to the one extension. After the section 11 is connected, one end of the first joint section 22 (that is, the end surface that is not connected to the first extension section 11) can be extended to connect to the first extension section 11 on the other joint 100. The second joining section 22 can also be fastened to the second positioning bodies 121 provided on the second extension section 12 through the second fixing portions 221, so that the second joining section 22 can be firmly connected to the After an extension section 11 is connected, one end of the second joint section 22 (that is, the end surface that is not connected to the second extension section 12) extends to be connected to the second extension section 12 on the other joint 100, The positions where the first positioning bodies 121 are connected to the first joint section 21 or the positions where the second positioning bodies 121 and the second joint section 22 are connected are adjacent to the setting position of the connecting plate 30. For example, the first joint section 21 is configured to cover a part of the first extension section 11, but not at the position of the connecting plate 30. Therefore, the first joint section 21 is only Is located adjacent to the connecting plate 30, so that the connecting plate 30 and the connecting section 30 and the first extension section 11 of the connecting plate 30 are exposed to the outside (the exposed part is formed Steel structure section (SS section)). In this way, the above-mentioned effect is achieved for joining another beam-column structure 200, for forming a beam, or other related purposes.

Therefore, according to the structure formed by the joint 100 and the beam-column structure 200 of this creation, it can be known that the part of the beam-column structure 200 connected to the joint 100 can be a reinforced concrete section (RC section), The beam-column structure 200, the first or second joint section (21, 22) and the connecting part 100 are steel-reinforced concrete sections (SRC sections), which are not connected to the beam-column structure 200, The connected part of the first or second joint section (21, 22) (that is, the part of the connecting plate 30) is formed as a steel frame section (SS section). In this way, this creation can provide a composite beam-column structure of reinforced concrete, steel-reinforced concrete and steel-framed structure, thereby improving the problems of traditional reinforced-concrete soil structure, and can also solve the problem of steel-reinforced concrete structure. , Labor and construction time increase costs.
