Description

Unit type windowsill line installation structure based on double-sided laminated wallboard Technical Field The utility model relates to a windowsill line installation structure, in particular to a unit windowsill line installation structure based on double-sided laminated wallboards. Background In the construction industry, "window sill line" generally refers to a horizontal and transverse decorative strip protruding from a wall surface, and is positioned on the outer side of the bottom of a window cavity, and has waterproof and decorative functions. The existing windowsill line installation structure is generally divided into the following several types: 1) In the traditional cast-in-place concrete wall, the windowsill lines are cast and formed with the wall synchronously through the formwork support, the modeling formwork is designed in advance, the construction period is long, and the requirement on the accuracy of the formwork is high. In the prefabricated wallboard, lines can be pre-buried in the wallboard, but are limited by the production process, and complicated modeling is difficult to realize, and especially the sandwich heat-insulating wallboard is more difficult to be in an outward convex modeling due to the obstruction of a heat-insulating layer. 2) And after finishing the wall, the lines (such as GRC, EPS, stone and the like) are installed in sections and fixed by bolts, adhesives or steel frames. The joint needs to be cut and adjusted on site, and the joint needs to be additionally treated (such as gluing and plastering), so that the problems of cracking and leakage are easy to occur, and the integrity is poor. 3) And depending on an auxiliary supporting structure, the overhanging lines need to be additionally welded or provided with a steel bracket for bearing, so that the construction complexity is increased, and the heat preservation continuity can be influenced. Disclosure of Invention The utility model aims to provide a unit type windowsill line installation structure based on double-sided laminated wallboards, which is actually an installation form of 'post-installation type integral installation', and solves the technical problems pointed out by 'post-installation type sectional splicing'. The utility model adopts the following technical scheme: The utility model provides a unit formula windowsill line mounting structure based on double-sided coincide wallboard, includes unit formula line 2, lower unit formula line 6, connecting screw 8, double-sided coincide wallboard 1, the upper edge and the lower edge of the reservation window opening of double-sided coincide wallboard 1 all are equipped with first reservation PVC hole 5, unit formula line 2, lower unit formula line 6 are equipped with respectively with the corresponding second reservation PVC hole 7 that communicates of first reservation PVC hole, connecting screw 8 pass first reservation PVC hole 5 and second reservation PVC hole 7 and fix unit formula line 2, lower unit formula line 6 respectively on double-sided coincide wallboard 1 through the nut. In this technical scheme, all form the reservation PVC hole through pre-buried PVC sleeve pipe on line and the interior leaf board when the mill is prefabricated to realize the line with two-sided coincide wallboard through connecting screw and to drawing to be connected, thereby form a unit formula windowsill line mounting structure based on two-sided coincide wallboard, the line is as a complete module (like whole windowsill length) disposable installation, and avoided "need on-the-spot cutting, adjustment piece joint that the segmentation concatenation brought among the prior art, the seam part needs additional treatment (like gluing, plastering), the easy fracture problem that appears, the leakage problem, the wholeness is relatively poor" scheduling problem. Preferably, a reserved tongue-and-groove 4 is arranged at the inner blade plate of the lower edge of the reserved window hole of the double-sided laminated wallboard, the reserved tongue-and-groove 4 is arranged above the first reserved PVC hole 5, and the lower unit line 6 can be partially embedded into the reserved tongue-and-groove 4. As the main stress part of the windowsill or the decorative line, the windowsill or the decorative line is required to directly bear dead weight, external load (such as wind pressure and rain impact) and temporary load in the construction stage. The tongue-and-groove is meshed with the concrete layer of the double-sided laminated wallboard, mechanical interlocking is formed after cavity concrete is poured, the integrity is enhanced, and meanwhile, the tongue-and-groove can form a drainage gradient or a water retaining edge, so that rainwater is prevented from flowing back to a wall joint. Furthermore, a reserved tongue-and-groove is not arranged at the inner blade plate of the upper edge of the reserved window hole of the double-sided laminated wallboard. The upper line is not provided with
