Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a quick-release plate for beam end joints and a construction method thereof. Background Technology

[0002] In building construction, especially in basement structures, beams are often poured in sections due to process requirements or workspace limitations, resulting in construction joints between adjacent beams. The traditional method for handling these joints is to use wire mesh as a sealing template. Specifically, when setting up formwork at the beam ends, a layer of wire mesh is fixed at the construction joint location, then concrete is poured. After the concrete hardens, the exposed wire mesh is manually removed.

[0003] However, this traditional method has significant drawbacks: First, chiseling the wire mesh is a tedious, time-consuming, and labor-intensive post-processing procedure, which severely restricts construction efficiency and increases labor costs; second, because the wire mesh is embedded in the concrete, it is difficult to completely remove it, and the remaining wire mesh can cause appearance defects such as honeycomb and pitting on the concrete surface at the joints; more importantly, incomplete chiseling will damage the density and integrity of the concrete in the joint area, creating a weak link in the structure's waterproofing, which can easily lead to leakage problems in later use, seriously affecting the durability and functionality of the building structure.

[0004] Therefore, in view of the problems of complicated procedures, difficulty in ensuring quality, and easy leakage in the treatment of construction joints at beam ends in the existing technology, there is an urgent need for a device and method that can achieve rapid installation and removal, eliminate the need for chiseling, and ensure the quality of joint formation. Summary of the Invention

[0005] The main objective of this invention is to propose a quick-release plate for beam end joints and a construction method to solve the technical problems of difficult chiseling, low efficiency, poor joint quality, and easy leakage caused by the traditional wire mesh interception method.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-release plate for beam end joints includes: an upper plate and a lower plate that can be spliced ​​and fixed together; the top of the upper plate has at least two first U-shaped slots for clamping the upper beam reinforcement; the bottom of the lower plate has at least three second U-shaped slots for clamping the lower beam reinforcement.

[0008] Preferably, the upper plate and the lower plate are locked together by at least one detachable snap fastener.

[0009] Preferably, the buckle is a rotary buckle, a pin buckle, or a bolt fastener.

[0010] Preferably, the splicing surfaces of the upper and lower plates are provided with matching concave and convex structures or guide strips for quick positioning and error-proof installation.

[0011] Preferably, the inner walls of the first and second U-shaped grooves are provided with an elastic buffer layer or anti-slip texture.

[0012] Preferably, the quick-release plate is made of sheet metal, engineering plastic or composite material, and its surface is coated with a release agent or anti-rust coating.

[0013] A construction method for beam end joints, using the aforementioned quick-release plate for beam end joints, includes the following steps:

[0014] S1. Reinforcing bar alignment and installation: After the reinforcing bars of adjacent beams are tied, insert the quick-release plate into the construction joint between the ends of the beams, so that the beam reinforcing bars are respectively inserted into the first U-shaped groove of the upper plate and the second U-shaped groove of the lower plate.

[0015] S2. Formwork fixing: Adjust the position of the quick-release plate to make it close to the beam end section, then lock the buckle to fix the upper plate and the lower plate as one piece, and ensure that the formwork does not shift during the concrete pouring process;

[0016] S3. Concrete pouring: The concrete pouring and vibration of the beam body is carried out.

[0017] S4. Formwork Removal: After the concrete reaches the predetermined strength, first release the locking of the clips, and then use a pry bar or special dismantling tools to separate and remove the upper and lower plates from the construction joint.

[0018] Preferably, in step S4, the removed quick-release plate, after cleaning and maintenance, can be reused for other similar beam end joint constructions.

[0019] Preferably, between steps S1 and S2, the following step is also included: checking and ensuring that the joint between the quick-release plate and the beam end formwork is tight, and sealing it with a sealing strip if necessary to prevent concrete leakage.

[0020] This invention provides a quick-release plate for beam end joints and a construction method, which has the following beneficial effects.

[0021] This invention utilizes modular, reusable, and prefabricated quick-release panels, completely eliminating the chiseling process required for traditional wire mesh. Installation and dismantling are fast, significantly reducing construction time and labor costs. As a rigid formwork, the quick-release panels effectively seal joints, preventing concrete leakage and ensuring dense, smooth concrete surfaces at joints, eliminating common quality defects such as honeycombing and pitting, and preventing leakage risks at the source. The U-shaped slots on the upper and lower panels engage with the beam reinforcement, enabling quick and accurate positioning and fixing of the formwork, ensuring precise joint placement and simple, easy construction. The quick-release panels can be reused multiple times, resulting in low wear and tear, reducing material waste and construction debris associated with the single-use of traditional wire mesh, aligning with green construction principles.
