Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building construction tool design, and particularly relates to an external corner strip for preventing slurry leakage of laminated plates. Background Art
[0002] In recent years, the building 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. 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. This method 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 at the external corners of the bottom formwork of prefabricated laminated plates in building projects. Content of the Utility Model
[0003] Aiming at the deficiencies existing in the prior art, the utility model provides an external corner strip for preventing slurry leakage of laminated plates, which can effectively avoid slurry leakage at the bottom of laminated plates when pouring concrete and control the construction forming quality of prefabricated structures.
[0004] The utility model realizes the above technical purpose through the following technical means.
[0005] An external corner strip for preventing slurry leakage of laminated plates includes two parts: an external corner strip and a sponge strip. The cross-section of the external corner strip is in an inverted "L" shape. A plurality of round holes are evenly arranged at intervals along the length direction on both surfaces of the external corner strip. The sponge strip is a long strip structure with the same length dimension as the external corner strip, and its cross-section is in a semi-circular shape. The flat surface of the sponge strip is adhesively fixed to the outer side of one surface of the external corner strip.
[0006] Further, the external corner strip is made of PVC material.
[0007] Further, the cross-section size of the external corner strip is 10×10 mm, and the thickness is 1 mm.
[0008] Further, a plurality of round holes with a diameter of 6 mm are arranged at intervals of 10 mm along the length direction on both surfaces of the external corner strip.
[0009] Further, the cross-section of the sponge strip is in a semi-circular shape and the diameter of the semi-circle is 10 mm.
[0010] Further, during the construction of preventing slurry leakage of laminated plates, the external corner strip is connected to the formwork through glue or nails, and the intersection part between the laminated plate and the external corner of the bottom formwork of the laminated plate is pressed on the sponge strip to form a seal.
[0011] The utility model has the following beneficial effects:
[0012] It is installed at the external corner position of the bottom formwork of the composite slab without being removed, with simple and quick operation;
[0013] It can seal the gaps within 5 mm in width, effectively prevent mortar leakage, and ensure the forming quality of the prefabricated structure construction;
[0014] The material is PVC and sponge strip, with low cost, and can be cut into appropriate lengths as needed;
[0015] After the formwork is removed, the internal corner is straight and the forming effect is good. Description of the Drawings
