Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete beam reinforcement, in particular to a prestressed concrete beam reinforcement device. Background Art
[0002] Concrete beams are common load-bearing components in building structures. They are mainly composed of concrete and steel bars. They bear the weight of the building, including its own weight, live loads such as crowds, equipment, wind loads, and other loads such as earthquakes. Concrete beams are widely used in various types of construction and bridge projects due to their good bearing capacity and economy.
[0003] Concrete beams are important load-bearing components in building structures. In frame structures, beams connecting columns or walls bear loads from floors, roofs, etc., and transfer these loads to columns or walls. Their design, construction, and quality control are of great significance to ensuring the safety and durability of buildings. Currently, people on the market often use reinforcement devices when performing prestressed reinforcement on concrete beams.
[0004] However, existing prestressed reinforcement devices for concrete beams are usually composed of multiple components, including prestressed tendons such as steel strands or wire bundles, anchors, turning blocks, grouting materials, etc. This structure increases the difficulty of design and manufacturing, and most of them use fixed prestressed tendons and anchors. After installation, the prestress value cannot be changed. When the load changes, the prestressed state of the concrete beam will change, and the reinforcement device is difficult to adjust, resulting in cracking of the concrete beam. Utility Model Content
[0005] The purpose of the utility model is to provide a prestressed reinforcement device for concrete beams to solve the problem that the existing prestressed reinforcement device for concrete beams uses fixed prestressed tendons and anchors, which are difficult to adjust and thus cannot adapt to new stress states, resulting in cracks in the concrete beams.
[0006] To achieve the above-mentioned purpose, the basic solution provided by the utility model is: a prestressed reinforcement device for concrete beams, comprising a concrete beam body and two reinforcement frames, the concrete beam body being located on the reinforcement frames, each of the reinforcement frames being provided with a connector for connecting the concrete beam body on one side, each of the reinforcement frames being provided with a side plate on one side, each of the side plates being provided with a damper, each of the dampers being provided with a fixed plate, each of the fixed plates being provided with a spring, one end of each of the springs being connected to the reinforcement frame, a reinforcement plate being provided between the two fixed plates, and a support assembly for supporting the concrete beam body being provided on the reinforcement plate.
[0007] The working principle of the utility model is as follows: when it is necessary to install a reinforcement device on the concrete beam body, first the reinforcement frame is overlapped on the bottom of the concrete beam body, and then the concrete beam body and the reinforcement frame are fixed by a connecting piece, and then the screw is rotated, and the screw rotates in the sleeve. As the screw rotates, the sleeve moves upward along the outside of the screw until the sleeve fits with the bottom of the concrete beam body to complete the installation; when the load of the concrete beam body changes, the sleeve is subjected to downward force, and the force is transmitted to the fixed plate by the reinforcement plate. At this time, the fixed plate stretches the spring, and at the same time relies on the support of the damper on the side plate to reduce the vibration amplitude of the reinforcement device.
[0008] The beneficial effect of the utility model is that: by arranging springs and dampers, the reinforcement device can adaptively adjust when the load of the concrete beam body changes, adapt to the new stress state, reduce the vibration amplitude, and effectively avoid cracking of the concrete beam. During installation, it is only necessary to overlap the reinforcement frame on the bottom of the concrete beam body and then fix it with the connecting parts. The operation is simple and quick.
[0009] Option 2 is the preferred option of the basic option. The support assembly includes several U-shaped plates, each of which is threaded with a screw, and each of which is threaded with a sleeve. By setting up several U-shaped plates, screws and sleeves, the height can be adjusted according to the specific size and shape of the concrete beam body, so as to better adapt to concrete beams of different specifications and improve the versatility of the reinforcement device.
[0010] Option three is a preferred option of option two, in which a support column is rotatably connected to the sleeve; the support column is rotatably connected to the sleeve, which increases the contact area with the concrete beam body and makes the support more uniform.
[0011] Option 4 is a preferred option of Option 2, in which a knob is provided at the bottom of the screw; the knob is provided at the bottom of the screw to facilitate manual adjustment by the operator without the aid of other complex tools, thereby improving the convenience of operation.
[0012] Option 5 is the preferred option of the basic option. The connecting member is a fixing bolt. Using a fixing bolt as the connecting member makes the connection firm and reliable, and is easy to install and disassemble, making it convenient to maintain and replace the reinforcement device.
[0013] Option six is a preferred option of the basic option. A telescopic rod is provided on the fixed plate, one end of the telescopic rod is connected to the reinforcement frame, and the telescopic rod is located inside the spring. The telescopic rod is provided on the fixed plate and located inside the spring to guide the expansion and contraction of the spring and prevent the spring from being offset or twisted during the stretching and compression process.
