Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building and bridge engineering, and particularly relates to an easily detachable perforated rigid connection node. Background Art
[0002] At present, wet joints are used to connect segmental concrete beam components such as prefabricated cap beam segments. When performing high-altitude operations on wet joints, there are often traffic requirements, which makes it inconvenient to use ground-based support for construction. Wet-joint concrete construction requires the installation and disassembly of formwork, and horizontal rods are often used to pull the lateral formwork together, which bears little tension and force. However, for side formwork that is operated at high altitude and is not supported by ground-based support, the horizontal rod must not only withstand tension, but also withstand the bending and shearing caused by the self-weight of the formwork and wet-joint concrete. The connection nodes are subjected to complex forces and require strong bearing capacity. In addition, in order to improve the efficiency of high-altitude construction, the connection points must be easy to install and remove. Traditional connection nodes are difficult to adapt to complex construction conditions, which has an adverse effect on construction safety and work efficiency. Utility Model Content
[0003] In order to improve the construction quality, the present application provides an easily detachable perforated rigid connection node, which has a strong bearing capacity and high installation and removal efficiency.
[0004] The utility model is realized through the following technical solutions.
[0005] The utility model discloses an easily detachable perforated rigid connection node, which comprises a horizontal rod, a connection piece, a vertical rod, a limiting plate and a steel pad.
[0006] The horizontal rod is composed of channel steel and has a rectangular cross-section. Two groups of limit plates are respectively provided above the two ends of the horizontal rod. The spacing between the two groups of limit plates along the horizontal rod direction is nested with the width of the connecting piece along the horizontal rod direction; the connecting piece is a box-shaped body composed of two vertical steel plates I and two vertical steel plates II. Rectangular holes are provided on the two vertical steel plates I opposite to each other along the horizontal rod direction of the connecting piece, and the height of the rectangular hole is ≥ the height of the horizontal rod plus the height of the limit plate. The horizontal rod is lifted upward through the rectangular hole of the connecting piece, and a steel pad is inserted into the lower part of the horizontal rod, which is embedded in the connecting piece through the two groups of limit plates; the vertical rod is located at the lower part of the connecting piece, and the top end of the vertical rod is flush with the lower opening of the rectangular hole of the connecting piece, and is fixedly connected in the connecting piece.
[0007] The installation process of the utility model is as follows: after the horizontal rod passes through the rectangular hole of the connecting piece, the horizontal rod is lifted up to make it tightly pressed against the upper part of the rectangular hole, and the limit plates clamp the horizontal rod to the upper part of the connecting piece one after the other, and then a steel pad is inserted into the lower part of the horizontal rod in the rectangular hole and squeezed tightly to prevent the horizontal rod from falling, thereby completing the fixed installation of the entire structure.
[0008] The disassembly process of the utility model is as follows: when disassembling, the steel pad is first removed, and then the horizontal rod is lowered to the lower end of the rectangular hole, and then the horizontal rod is slid out of the rectangular hole, thereby completing the disassembly of the entire structure.
[0009] Compared with the prior art, the utility model has the following beneficial effects: the easily detachable perforated rigid connection node of the utility model has a simple structure and is easy to operate. It is used for the rapid assembly of the wet joint formwork support of the road cap beam, which is convenient for installation and dismantling during construction, can effectively improve work efficiency, and save construction time and cost.

Rectangular holes 7 are opened on the two vertical steel plates Ⅰ5 opposite to each other in the direction of the horizontal rod 1 of the connecting member 2, and the height of the rectangular hole 7 is ≥ the height of the horizontal rod 1 plus the height of the limit plate 4. The horizontal rod 1 is lifted upward through the rectangular hole 7 of the connecting member 2, and a steel pad 8 is padded at the bottom of the horizontal rod 1, which is embedded in the connecting member 2 through the two groups of limit plates 4; the vertical rod 3 is located at the bottom of the connecting member 2, and the top of the vertical rod 3 is flush with the lower opening of the rectangular hole 7 of the connecting member 2, and is fixedly connected to the connecting member 2; a movable steel pad 8 is provided between the tops of the horizontal rod 1 and the vertical rod 3.
[0018] The installation process of the utility model is as follows: after the horizontal rod 1 passes through the rectangular hole 7 of the connecting piece 2, the horizontal rod 1 is lifted up so that it is pressed tightly against the upper part of the rectangular hole 7, and the limit plates 4 clamp the horizontal rod 1 on the upper part of the connecting piece 2 one after the other, and then a steel pad 8 is inserted into the lower part of the horizontal rod 1 in the rectangular hole 7 and squeezed tightly to prevent the horizontal rod 1 from falling, thereby completing the fixed installation of the entire structure.
[0019] The disassembly process of the utility model is as follows: when disassembling, first remove the steel pad 8, then lower the horizontal rod 1 to the lower end of the rectangular hole 7, and then slide the horizontal rod 1 out of the rectangular hole 7, thereby completing the disassembly of the entire structure.
