Description
Technical Field
The utility model relates to the technical field of embedded parts, in particular to a T-shaped open-pore embedded part.
Background
Reinforced concrete structures have been used in many applications as one of the main forms of building structures in China, but have limited use in areas with high earthquake intensity, so that the support is often required to be arranged inside the structure to improve the earthquake-resistant performance of the structure. The steel support and the main body structure are subjected to stress transmission mainly through the embedded part preset in the concrete beam column, so that the bearing capacity of the embedded part directly influences whether the support can enter a working state according to expectations.
At present, main stream embedded parts mainly comprise anchoring type embedded parts, H-shaped steel embedded parts and steel rib embedded parts, all three embedded part forms have certain application scenes, but the three embedded part forms have some limitations, such as the anchoring type embedded parts are not suitable for supporting with large bearing capacity, the lower flange plates of the H-shaped steel embedded parts are often interfered with beam column steel bars, the steel rib embedded parts are poor in economy, and the construction is relatively troublesome.
Disclosure of Invention
The utility model provides a T-shaped open-pore embedded part for solving the technical problems in the prior art.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a T type trompil formula built-in fitting, includes anchor slab, peg, tip trompil web and perforation reinforcing bar, the bottom of anchor slab and the top fixed connection of web strip form T type structure, web strip interval arrangement in anchor slab length scope, and the clearance between the adjacent web strip is used for the arrangement of beam column stirrup, the peg is arranged in web strip both sides, and is fixed with the anchor slab, the web strip is equipped with a plurality of trompils in keeping away from the anchor slab end, perforation reinforcing bar passes the trompil on the web strip.
Preferably, the peg and anchor plate are secured by welding.
Preferably, the fixing position of the web plate strip and the anchor plate is the middle part of the anchor plate.
Preferably, the bottom of the anchor plate is welded with the top end of the web strip.
Preferably, the anchor plate and the web plate strip adopt double-side fillet welds or full penetration welds.
Preferably, the center of the web strip open hole is located on the center line of the web strip, and the number of open holes on the same web strip can be one or more.
Preferably, the opening is a round hole.
Preferably, the diameter of the round hole is larger than that of the perforated steel bar, and a certain gap is reserved in the round hole by the perforated steel bar.
Preferably, the two ends of the perforated steel bar extend out of the web plate strip by equal distances.
When the support arranged obliquely transmits the axial force, the embedded part receives the pulling-shearing compound force. The web plate strips and the pegs are in contact with the concrete and are extruded to provide shearing bearing capacity for the embedded part, meanwhile, the web plate strips can also provide tensile bearing capacity, and when the web plate strips are pulled, tensile force is transmitted to the concrete part and the perforated steel bars in the gaps of the round holes, so that the concrete part and the perforated steel bars in the gaps of the round holes are sheared. When the tensile bearing capacity of the embedded part is insufficient, multiple holes can be formed in the web plate strips, so that the overall stress performance of the embedded part is improved.
The utility model has the beneficial effects that:
1. compared with the existing embedded part type, the T-shaped open-pore embedded part has the advantages that the higher bearing capacity is considered, meanwhile, the construction difficulty is greatly reduced, and the popularization and the application in the construction engineering are facilitated.
The shearing resistance and the tensile resistance of the T-shaped open-pore embedded part can be determined by adjusting the quantity of the web plate strip, the bolt and the web plate strip openings, and the T-shaped open-pore embedded part is multiple in adjusting mode and simple and convenient to design.

Description of the embodiments
The technical scheme of the utility model is further specifically described below through examples and with reference to the accompanying drawings.
Examples: a T-shaped open hole embedded part, as shown in figures 1-3, comprises an anchor plate, a bolt, a web plate with open holes at the end and a perforated steel bar. The anchor plate is welded with one end of the web plate strip, and a T-shaped joint is adopted, and the anchor plate and the web plate strip are connected by double-side fillet welds or full penetration welds. The web strips are arranged at intervals within the length range of the anchor plate, and gaps between adjacent web strips are used for arranging beam column stirrups. The welding position of the web plate strip and the anchor plate is the middle part of the anchor plate. The pegs are arranged on two sides of the web plate strip and welded with the anchor plate. The web strip is provided with a circular opening at the end far away from the anchor plate. The center of the web plate strip open hole is positioned on the center line of the web plate strip, and the number of the open holes on the same web plate strip can be one or more. The perforated steel bar passes through the round holes on the web plate. The perforated steel bar can reserve certain clearance in the round hole. The distance that the two ends of the perforated steel bar extend out of the web plate strip is equal.
The embedded part can be installed before beam column steel bar binding, and also can be installed after beam column steel bar binding, so that coordination of construction procedures is reduced. The perforated steel bars in the embedded part can be fixed with the web bars through spot welding, and also can be fixed with the steel bars in the beam column through binding, so that the installation degree of freedom is higher.
Stress principle of T-shaped open-pore embedded part: the web plate strips and the pegs provide shearing bearing capacity for the embedded part, concrete and perforated steel bars in the gaps of the round holes can provide pulling bearing capacity for the embedded part, and the pulling resistance of the embedded part can be improved by increasing the number of the holes in the web plate strips.
The foregoing is a further detailed description of the presently preferred embodiments of the present utility model, and is not intended to limit the practice of the utility model to the particular embodiments described, but rather to limit the scope of the utility model.
