Description

[Detailed description of the invention] This invention relates to an earthquake-resistant and fire-resistant wall body used as a prefabricated building material.
Hard lath (expanded metal) is electrically welded to create a strong wall frame structure, with built-in bolt attachment devices for interconnection around the wall frame, and mortar or tile on the surface of the wall frame. The wall frame is filled with clay gold ingots and painted to make it earthquake-resistant, fire-resistant, sturdy, and safe, and factory production shortens the construction period and is inexpensive and easy to assemble, making it possible to build houses and buildings. This is what we intend to provide.

The present invention will be explained below based on the drawings. Reference numeral 1 denotes an outer frame configured in a square or rectangular shape using L-shaped steel 2;
Reinforcing bars 3 are placed over the inner edge of the section steel 2, and reinforcing materials 4 are placed in several stages above and below.
are connected by electric welding, and a steel plate 7 for attaching to a structure is welded to the upper surface of the outer frame 1, forming inner and outer protruding edges 6, 6' having bolt holes 5, 5' at predetermined positions, respectively. A solid wall frame 8 is constructed, and a metal hard lath 9 called expanded metal is placed on the surface of this wall frame 80, and an appropriate number of bracings 10 are arranged thereon and electrically welded at predetermined intervals. Around the wall frame 8, there are an appropriate number of bolt holes welded to each nut 12 having a cap 11 inside at appropriate intervals on the upper side and one side on both left and right sides. 13,13
......, and the bolt hole 1 on the other side and bottom side.
An appropriate number of bolt holes 16, 16 are fully provided, with metal boxes 15 each having a gap 14 for attaching a connecting bolt, which opens only on the rear surface, welded to the opposing positions of 3 and 13, respectively.
Mortar or tiles 17 are pasted on the front side of the hard lath 9, and 6jt of clay 18 is mixed into the wall frame 8 on the back side.
It has a structure in which a prefabricated earthquake-resistant and fire-resistant wall body 19 is formed by filling and painting, and 20 is a protrusion having a bolt hole protruding inwardly and outwardly on both sides of the outer frame 1 of the wall frame body 8. It is.

Figures 3 and 4 show a wall 19' having the above-mentioned wall structure, in which equipment necessary for daily life such as electricity, gas, water, etc. to be introduced from outdoors to indoors is embedded in the wall in advance. So, 21
22 is a window frame embedded in a wall frame 24 made of L-shaped steel;
is a ventilation fan, 23 is an electric wire introduction pipe, 23' is an entrance of the electric wire introduction pipe, 25 is an outlet, 26 is an electrical safety device, 27 is an internal
The water pipe is equipped with a water tap 28 and a water pipe connection plug 29 on the outside, and is buried in the clay 18 within the wall frame 24.
31 is a drain pipe insertion hole, and 31 is a gas pipe introduction hole, and by burying devices for introducing daily necessities such as these in advance, it is effective to lengthen the entire exterior, reduce facility costs, and shorten the construction period.

Figures 5 and 6 show the cost when the entire entrance is attached to a wall frame 37 made of L-shaped steel. 32 is a light window, 33 is a sliding door, and they are framed separately to prevent breakdowns due to earthquakes, etc. In order to reduce the number of sliding door frames 36
It was installed on 7.

When assembling a building such as a house using the earthquake-resistant and fire-resistant wall of the present invention, the wall 19 is arranged upright on the foundation, and the lower part is connected to the box with anchor bolts or connection bolts through the bolt holes 16. 15, and the left and right connecting portions of the wall 19 are connected to the inner side of one side of the wall 19 adjacent to the nut 12 having the built-in cap 11 provided on one side, as shown in FIG. The connecting bolts 38 are fully screwed through the bolt holes 16 and 13 from inside the provided box metal 15 to fully connect the wall sides. A nut 12 with a cap 11 is mounted on a similar wall 19 and fixed to the lower wall 19 from inside the box metal 15 through a connecting bolt hole 16.13 as shown in FIGS. 8 and 9.
In this way, each wall body 19, 19,
...and a wall 19' in which connection equipment such as electricity, gas, water, etc. necessary for daily life is buried from the outdoors to the indoors,
The wall frames 37 forming entrances and exits are connected by the same connecting means as described above, and the bolt holes 5 of the steel plate 7 attached to the wall 19 are connected.
A support member for the floor or roof of the upper floor is bolted onto the joint inner chiseled edge 6, and a support member for a veranda, passageway eaves, roof, etc. is connected to the outer protruding edge 6' having bolt holes 5'. The protrusions 20, 20 that are fully attached and supported, and that protrude inwardly and outwardly from both sides of the walls 19, 19, etc., are used to attach small beams, hanging shelves, etc. to the inner protrusions 20 when the walls are joined. The internal mounting structure is installed as a connection point for all structures, and the external protrusion 20 is installed as a support connection point for pillars such as balconies, passageways, eaves, etc., and a prefabricated house as shown in Fig. 11 is constructed. be.

As explained above, the wall body of this invention has all the voids so that nuts and bolts can be attached to the inner periphery of the outer frame made of L-shaped steel of the wall frame body, and have caps fixed and buried opposite the sides at predetermined intervals. With the metal box, it is possible to connect the walls to each other and securely attach them to the foundation using connection bolts, invisible from the outside, and also connect the walls on the upper floor in the same way to the steel plate attached to the top of the wall. At the same time, the inner and outer edges of the steel plate can be connected to the floor or roof of the upper floor, and the outer edges can be connected to attached structures such as roofs and balconies.
Houses can be constructed simply and easily, and they can be easily dismantled and relocated.Moreover, the walls span the outer frame and are fixedly stretched with reinforcing bars, metal hard laths, and reinforcement bones by electric welding. Since the surface is made of mortar or tiles and the inside of the frame is filled with clay and painted, it becomes a strong, strong and non-combustible wall that can withstand shocks and external forces from the four circumferential sides as well as from the front and back. Excellent earthquake and fire resistance.

Therefore, it is safe against earthquakes and fires, and in particular, non-combustible houses can act as a barrier against the spread of fires, especially against the risk of simultaneous multiple fire outbreaks caused by earthquakes and large fires caused by strong winds.

In addition, this wall body can be produced in a factory, so the manufacturing price is low, and it is easy to install on-site, shortening the construction period, and making it possible to provide houses, factories, and other buildings at low prices.

Furthermore, since the wall is entirely made of clay, it is easy to adjust the indoor humidity, which is not only effective for livability and health, but also has a solid mounting part exposed on the external wall surface assembled with this wall. Therefore, it is possible to install balconies, eaves, solar heat absorption devices, etc., and there are advantages such as the ability to easily create a unique design for the aesthetic appearance of the house.
