Description

Adjustable length wall sleeve The present invention relates to a wall sleeve, and more specifically, to a length-adjustable wall sleeve for improving construction efficiency through a length adjustment function of a sleeve installed on a wall of a building. Generally, building facilities refer to installations designed to improve the indoor environment and functionality, including various equipment such as electricity, telephone, high-speed information and communication, gas, water supply, drainage, ventilation, heating, fire extinguishing, and smoke exhaust. The above-mentioned building facilities are installed on the interior or exterior of walls formed of brick, concrete, or wood, etc., and it is necessary to install sleeves embedded in the walls to provide a passageway through which piping pipes interconnected to the facilities can pass through the walls. However, in conventional technology, sleeves had the inconvenience of requiring the separate manufacturing and installation of sleeves of various specifications corresponding to the wall thickness, as the thickness of the building wall being constructed varies variably depending on the structure. FIG. 1 is a cross-sectional structural diagram of a wall sleeve in a separated state according to one embodiment of the present invention. Figure 2 is an enlarged view of section A of Figure 1. Figure 3 is an enlarged view of section B of Figure 1. FIG. 4 is a separated perspective view of the sleeve body in the present invention. Fig. 5 is a sleeve support ring and French front structural diagram. FIG. 6 is a cross-sectional structural diagram of the wall sleeve connection state of the present invention. FIG. 7 is a schematic structural diagram of the state in which the sleeve support ring is connected to the reinforcing bar in the present invention. FIG. 8 is a diagram showing the state in which the wall sleeve of the present invention is installed on a concrete wall. FIG. 9 is a cross-sectional view of a first watertight packing portion according to another embodiment of the present invention. FIG. 10 is an enlarged cross-sectional view of section C of FIG. 9. FIG. 11 is a rear surface structure diagram of a first watertight packing according to another embodiment of the present invention. FIG. 12 is an exemplary sleeve body product of the present invention. Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art. Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted. First, the configuration of a length-adjustable wall sleeve according to one embodiment of the present invention is as follows through FIGS. 1 to 6.
