Description

Technical Field

[0001] The utility model relates to the technical field of crossbeam PC components, in particular to a crossbeam PC component. Background Art

[0002] In the field of construction, beam components are also a commonly used component used to support and fix structures such as floors and roofs. Beam components are usually made of materials such as steel or concrete, and have good load-bearing capacity and stability. In building design and construction, the size and quantity of beam components need to be designed and selected according to specific circumstances. This includes parameters such as the span, spacing, cross-sectional shape and size of the beam. At the same time, factors such as the load-bearing capacity, deformation, and connection method of the beam with other components need to be considered. The beam component plays a very important role in the building. It can not only support and fix the entire building structure, but also beautify the appearance of the building and improve the utilization rate of the building space. Therefore, in the field of construction, the selection and design of the beam components are crucial. The steel cage is an important component of the beam component, which is used to enhance the bearing capacity and tensile properties of concrete. The steel bar is the main component of the steel cage, which is used to enhance the tensile capacity of concrete. Among them, the tie bar is usually used to connect the steel cages in different parts to enhance the overall stability and bearing capacity of the cage structure. The tie bar is generally arranged along the length of the steel cage and connected to the main bar by binding. In special cases, in order to increase the bonding force between it and the concrete structure, the two ends of the tie bar will be bent. This bending treatment can increase the contact area and bonding effect between the tie bar and the concrete, thereby increasing the shear resistance of the overall structure.

[0003] However, in the above technical solution, both ends of the angled tie rod need to be bent 135° for installation. During on-site processing, in order to facilitate installation, one end of the tie rod is bent 90° and the other end is bent 135°. During installation, the 90° end is connected by a sleeve, and then the 90° is bent to 135° through the sleeve. Due to the large number of tie rods, the workers' physical strength is constantly consumed during the installation process, and the efficiency of installing the tie rods is continuously reduced, affecting the construction progress. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that in the prior art, some of the two ends of the tie bars need to be bent 135 degrees during the installation process. During on-site processing, in order to facilitate installation, one end of the tie bar is bent to 90 degrees and the other end is bent to 135 degrees. During installation, the end bent at 90 degrees is connected by a sleeve, and then the 90 degrees is bent to 135 degrees by the sleeve. Due to the large number of tie bars, the physical strength of the workers is constantly consumed during the installation process, the efficiency of installing the tie bars is continuously reduced, and the construction progress is affected. A crossbeam PC component is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a crossbeam PC component, including a connecting sleeve, the inner wall surface of the connecting sleeve near both ends is provided with internal threads, the directions of the two internal threads are opposite, two steel bar hooks are embedded at both ends of the connecting sleeve, and the outer surface of the two steel bar hooks near one end is provided with external threads.

[0006] Furthermore, one end of one of the steel bar hooks is fixedly connected to a limiting sleeve, and a limiting sliding rod is embedded on the inner wall surface of the limiting sleeve.

[0007] Furthermore, one end of the limiting sliding rod is fixedly connected to one end of another of the steel bar hooks, and the limiting sliding rod is in the shape of a quadrangular prism.

[0008] Furthermore, a nut ring is sleeved on the outer surface of the connecting sleeve, and the nut ring is integrally formed with the connecting sleeve.

[0009] Furthermore, one end of the two steel bar hooks away from the connecting sleeve is configured as a rounded corner.

[0010] Furthermore, the bending angle of the two steel bar hooks is 135°.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when in use, align one end of the two steel bar hooks with the connecting sleeves respectively, rotate the connecting sleeves, so that the two steel bar hooks are connected to the connecting sleeves through two internal threads and two external threads, and then put the two steel bar hooks on the positions where they need to be installed, continue to rotate the connecting sleeves, so that one end of the two steel bar hooks continues to penetrate into the interior of the connecting sleeves until the two steel bar hooks are clamped at the installation position, and the distance between the two steel bar hooks can be freely adjusted by the connecting sleeves as needed, which can match different installation positions, avoid on-site processing procedures such as shearing and welding of the tensioning bars, save time and labor, and reduce the possibility of on-site processing errors, thereby improving the installation quality and efficiency of each component.

[0013] 2. In the utility model, the limit slide rod slides inside the limit sleeve when the two steel bar hooks approach each other, and the quadrangular prism-shaped limit slide rod cooperates with the limit sleeve to prevent the two steel bar hooks from rotating relative to each other, thereby ensuring the normal operation of the components and improving the use experience. An electric open wrench is used to engage with the nut ring, and the connecting sleeve is driven to rotate through the nut ring, thereby effectively improving the installation efficiency. The nut ring and the connecting sleeve are cast through a mold to improve the structural strength. The exposed ends of the two steel bar hooks are polished into rounded corners to prevent the two steel bar hooks from scratching the body when taking them, thereby preventing injuries to the staff and improving safety during use. The angle of the two steel bar hooks is directly bent 135°, and the staff does not need to bend them through the sleeve on site, thereby saving manpower. BRIEF DESCRIPTION OF THE DRAWINGS
