Abstract
Description
Technical Field
[0001] This utility model relates to the field of barrier technology, specifically to a recyclable barrier for concrete pouring at beam-column joints. Background Technology
[0002] In high-rise buildings with high seismic resistance requirements, the concrete grade of walls and columns is generally required to be 2-4 grades higher than that of beams and slabs. This places high demands on the construction of the joints between high and low grade concrete. Traditional construction methods typically use wire mesh or quick-closing mesh, but these cannot bear loads independently and often fail to achieve the desired results.
[0003] The beam-column joint concrete pouring recyclable barrier is a tool used in the construction field when pouring different types of concrete at beam-column joints. High-rise building design typically follows the seismic design principles of strong columns and weak beams, strong shear and weak bending, strong joints, and strong anchorage, resulting in column and wall concrete grades being 2-4 grades higher than beam concrete grades. To ensure the core area concrete strength is the same as the column and wall concrete strength, the concrete joint must be located on the beam, with the upper part of the joint at least 500mm above the column edge (equivalent to one beam height), and the interface forming a 45-degree angle with the bottom of the beam. Previously, wire mesh or quick-closing mesh was commonly used as isolation materials, but this presented challenges in controlling the joint location and angle, and the barrier layer was easily breached during concrete vibration, damaging the core area concrete composition. The overall structure mainly consists of a beam and multiple barrier teeth set on the beam. These barrier teeth are arranged side-by-side to form an isolation zone, used to prevent the exchange of different types of concrete at the beam-column joint. These barrier teeth are detachably connected to the crossbeam, and the distance between adjacent teeth can be adjusted by appropriately increasing or decreasing the number of barrier teeth.
[0004] The description of a novel barrier for concrete pouring (publication number CN204552083U) mentions that it "includes a mounting plate and barrier teeth. Multiple barrier teeth are evenly spaced and fixedly mounted on the mounting plate at intervals. The barrier teeth are installed in elongated grooves formed laterally on the mounting plate and are fixed to the mounting plate by nuts. Furthermore, a pair of handles are installed on the mounting plate on the left and right sides of the elongated groove. Moreover, the barrier teeth are welded from reinforcing bars and bolts of the same diameter. Furthermore, the mounting plate is an L-shaped angle steel." However, the barrier in this prior art cannot flexibly adjust the spacing width, nor can it quickly remove mud from the barrier teeth, making it neither flexible nor convenient for practical use. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, a recyclable barrier for concrete pouring at beam-column joints is provided to solve the problems of existing barriers not being able to flexibly adjust the separation width, nor being convenient to quickly remove mud from the barrier teeth, and thus not being flexible, convenient, or practical.
[0006] To achieve the above objectives, a recyclable barrier for concrete pouring at beam-column joints is provided, comprising an installation plate and a central mud removal structure. A central fixing block is provided in the center of the installation plate, and hollow cavities are provided on both the left and right sides of the installation plate. A side movable plate is movably installed in the hollow cavity, and multiple sets of blocking teeth are fixed on the lower end faces of both the installation plate and the side movable plate. The central mud removal structure is installed between the multiple sets of blocking teeth fixed on the lower end face of the installation plate, and a side mud removal structure is installed between the multiple sets of blocking teeth fixed on the lower end face of the side movable plate. Both the central mud removal structure and the side mud removal structure can move on the blocking teeth.
[0007] Furthermore, the upper end face of the mounting plate is fixed with a horizontal partition plate on both the front and rear sides, and a handle is fixed in the middle of the upper end face of the mounting plate. Additionally, the left and right sides of the mounting plate are provided with two sets of external insertion holes.
[0008] Furthermore, the side movable plate has a side cavity, and the side movable plate is provided with multiple sets of internal insertion holes. Locking bolts are installed between the external insertion holes and the internal insertion holes that are aligned vertically on the same side, and the locking bolts are detachable.
[0009] Furthermore, two sets of guide rods are fixed on both the left and right sides of the central fixed block, and the other end of the guide rod extends into the side cavity of the side movable plate on the same side.
[0010] Furthermore, the upper end of the locking bolt is provided with a handle, and the lower part of the locking bolt is threaded with a fastening nut, and the fastening nut and the locking bolt are detachably connected.
[0011] Furthermore, the medium-sized sludge removal structure is provided with multiple sets of sleeves, and a connecting plate is fixed between each sleeve and an adjacent set of sleeves. Both the sleeves and the connecting plates are made of stainless steel.
[0012] Furthermore, a limiting block is provided at the lower end of the barrier tooth, and the middle mud removal structure and the side mud removal structure can move up and down between the upper end of the barrier tooth and the lower end limiting block.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The movable side plates on the left and right sides of the mounting plate of this utility model can be moved into the hollow cavity or pulled out from the hollow cavity, which makes it convenient and flexible to adjust the width of the movable side plates moving outward, so as to adjust the spacing between the two movable side plates appropriately, making it easier to control the separation width and making it more flexible and practical.
[0015] 2. After the side movable plate is adjusted to the length extending into the hollow cavity, it can be fixed by inserting a locking bolt between the upper and lower aligned outer and inner insertion holes on the same side, thereby ensuring that the side movable plates on both sides with the adjusted spacing cannot be loosened, and the separation is safe and stable; moreover, the locking bolt is convenient to install and disassemble, making it more convenient and practical.
[0016] 3. In this utility model, the mud removal structure on the middle mud removal structure on the lower end face of the mounting plate and the side mud removal structure on the lower end face of the side movable plate can move up and down, making it convenient to scrape off the mud attached to the barrier teeth, making cleaning convenient, fast and easy.
