Provided by

In addition, a waterproofing device for a seam of a prefabricated building wall is provided by the present invention, wherein the device also includes an internal airtight material connecting the adjacent vertical skeleton assemblies to each other.

Furthermore, the connector is slightly inclined downwards toward the outside, the inner and outer sides extending straight down from both the inner and outer edges of the upper side, and the lower and almost half of the upper side connected between them at about halfway between the inner and outer sides. It is made up of a ring that is made to fit inside the pedestal of the horizontal armature and extends straight up from the inner edge of the upper side, and is inserted in the fitting groove with the elastic spacer at the bottom of the upper horizontal armature assembly. At the top of the lower horizontal armature assembly is inserted the bottom of the horizontal arm assembly so that it can move vertically in the alignment groove with the elastic spacer interposed therebetween, and the bottom of the outer side is the base of the lower horizontal armature assembly through an air-tight sealant. Provided by this design is a waterproofing device for a prefabricated building wall characterized by being connected to an outer surface, and the like. All.

In addition, the connecting plate has a shape similar to that of the inner side, the bottom side, and the ring of the connecting material, with the top side inclined slightly downward toward the outside, the vertical alignment surface extending from the innermost edge of the upper side, and the outermost side of the upper side. This design is provided by a seam-proof waterproofing for a prefabricated building wall, consisting of accompanying surfaces extending straight down from the side edges, each of which is firmly secured to the inside of a corresponding part of the connector. .

Vertical skeleton assembly Ba-Bd is erected as shown in FIG. 3 showing the respective assemblies Bc and Bd. In other words, the trunk 14, which is a hollow and elongate member, consists of two wide sides 10, 11 and two narrow sides 12, 13. On the narrow side 12 of the vertical armature 1, a fitting hook 15 is made, and on the other narrow side 13, an elongated hollow hole 16 and a groove 17 opened toward the wide side 10 are made. The hook 15 has a Z-shaped side 15a with a first large fitting groove 18 and a second and third fitting grooves 19, 20 with an outer surface 15 perpendicular to the Z-shaped side 15a. On the outer surface 15b has a shoulder 21, between the other side 15c and the narrow side 12 of the assembly body, there is a shoulder 22, and on this narrow side 12 a set of stops Ears 23 and 24 are integrated. The supporting material 31 is installed on the outer surface 15b of the fitting hook 15 through the elongate connecting member 30 of the vertical skeletons 1c and 1d with the screw 32, and the supporting material 31 is formed on the outer surface ( 31a) and a curved surface 31b, which is bent in a ring shape to form the fourth large groove 33, are integrally formed, and the fifth and sixth grooves 34 and 35 are arranged on the curved surface 31b at the second end of the alignment hook 15. And a third small fitting groove (19, 20) facing each other, the second small fitting groove (19) and the fifth groove (34) are connected to each other by a connecting member 36 made of a heat insulating material to the vertical skeleton assembly (Bc) (or Bd , Ba or Bb).

The sealing materials 38 and 38 are sandwiched between the two stoppers 23 and 24 and between the grooves 37 formed in the outer surface 31a of the pedestal 31, and the slab plate 39 is connected to the sealing materials 38, 38. 38).

In the vertical skeleton assemblies Bc, Bd (or Ba, Bb) of adjacently adjacent building wall units (Ac, Ad) (or Aa, Ab), their respective large fitting grooves 17, 18, 33 face each other. 3, the two outer airtight materials (41, 42) and the inner hermetic material (43) is sandwiched between the grooves facing each other to maintain the waterproof and the adjacent vertical skeleton assembly (Bc, Bd) ( Or Ba, Bb).

In the vertical skeleton assemblies Bb and Bd adjacent up and down, their respective vertical skeletons 1b and 1d are formed with protrusions 1b 'and 1d' as shown in FIG. Connected to each other by 3).

Each of the horizontal skeletal assemblies Ca-Cd is shaped exactly like the vertical skeletal assembly Ba-Bd, as shown in FIG. 5, in which the assemblies Cb and Cd are shown, so that the components are vertical skeletons. The same reference numerals are used for the assembly, and description thereof will be omitted.

Two building wall units Aa, Ac (or Ab, Ad) neighboring up and down are connected by the assembly connector 50.

In the center of the ring 55 is formed integrally upwards, the upper and lower portions of the inner surface 53, the upper and lower extension surface (56, 57) consists of the inner surface 53 and one body, The surface 54 is suspended from the extension surface 58.

Note that the extension surface 58 may be separately adjustable from the outer surface 54 and may be adjustable in a screw so that the accompanying surface 73 of the connecting plate 70 and the lower edges of the extension surface 58 coincide with each other. Should be placed in.

The upper extension surface 56 is fitted into the first large fitting groove 18 of the upper horizontal skeleton assembly Cd through a downward C-shaped spacer 59 made of an elastic material, and the upper ring 55 is supported by the support member. Engaged in the groove 64 of 61, the upper portion of the assembly connection 50 material is bitten fixed to the upper horizontal skeleton assembly (Cd). The lower extension surface 57 is fitted to be movable up and down in the first large fitting groove 18 of the lower horizontal skeleton assembly Cb through an upward C-shaped spacer 59 made of elastic material, for example air like fleece. Passable airtight material 80 is inserted into the groove 79 formed in the extension surface 58 is pressed toward the outer surface (61a) of the backing material 61, the outer airtight material (41, 42) and the upper And the space D between the lower armature assembly is connected to the outside.

In this way, the prefabricated building wall of this invention is composed of a wall having a constant atmospheric pressure, thereby preventing rainwater from entering the room.

Left and right assembly connector (50, 50) extends to the opposite wall of the vertical skeleton assembly (Ba, Bb and Bc, Bd) is disconnected to the side as shown in Figure 2 left and right assembly connector (50, 50) Make a gap in between.
