Description

Technical Field

[0001] The utility model belongs to the field of the design of construction tools, and particularly relates to a tool for preventing slurry leakage and installing and positioning of laminated plates. Background Technique

[0002] In recent years, the construction industry has vigorously developed prefabricated buildings. Among them, prefabricated laminated plates have been widely used in various housing construction projects. However, the phenomenon of slurry leakage is common when pouring concrete at the intersection of laminated plates and beams or walls. Moreover, when the laminated plate extends into the beam or wall by 10 mm, it is greatly affected by the operation of the hoisting workers during installation, and the error of the extension length in each direction is not controlled. At present, the common method for preventing slurry leakage at the bottom of prefabricated laminated plates is to paste double-sided tape. When the flatness deviation between the formwork and the laminated plate is too large, the double-sided thickness is insufficient, and the slurry leakage phenomenon cannot be completely prevented. Moreover, the current hoisting and positioning of laminated plates are measured by manual tape measures and visually positioned, and the installation deviation cannot be effectively controlled. The above traditional methods can no longer meet the trend of high-quality development of construction projects. Therefore, combined with engineering construction experience and reasonable design, the utility model designs a tool for preventing slurry leakage and installing and positioning at the intersection of prefabricated laminated plates and walls or beams in construction projects.

[0004] The utility model realizes the above technical purpose through the following technical means.

[0005] A tool for preventing slurry leakage and installing and positioning of laminated plates includes a sealing strip and an installation positioning piece; the sealing strip is made of a galvanized rectangular steel pipe, and a plurality of round holes A are symmetrically arranged at equal intervals on both sides of the sealing strip for installing screws. A sponge strip with a semi-circular cross-section is pasted on the top surface of the sealing strip; the installation positioning piece is made of galvanized flat iron, and the installation positioning piece is a right-angle bending structure, which is divided into three parts: a connecting section, a bending section, and a positioning section. The connecting section is used to connect with the sealing strip, and a round hole B is arranged at the center position of the connecting section for installing screws; a plurality of installation positioning pieces are installed and fixed on one side of the sealing strip through screws.

[0006] Further, the sealing strip is a galvanized rectangular steel pipe with a cross-sectional size of 15×15 mm and a wall thickness of 2 mm, and the length of a single sealing strip is 1 m; the length of the connecting section is 15 mm.
