Abstract
Title of the Invention Method for Constructing Flush Wall Lathing Abstract of the Disclosure According to a method for constructing a flush wall lathing by providing wallboard fixings at a given interval for adjusting and levelling the wallboard fixing surface of the fixings with a screw, and placing the wallboard to the wallboard fixing means, a lathing having a uniform surface can be easily and efficiently constructed, and what is more, it is possible to form a continuous space between a wall and wallboard suitable for injecting and filling insulating material such as foaming plastics or the like.
Description
In constructing walls for buildings and houses of reinforced concrete or of co~crete blocks, it is a common practice to provide flurring strips on the surface of the wall body and a wallboard is placed thereupon to ~orm A lathing. This flurring strip method involves considerable ~kill and time in order to achieve a uniform lathing surface, and when the wall is made of roughly finished concrete with irregular surface, it is necessary to coat the wall with mortar to prepare the flush surface before placing flurring strips, When the construction budget does not allow a mortar finish, i~ is necessary to interpose wooden strips and the like having a suitabl~ thic~ness between the wall and the ~lurring strips to correc~ the irregular surface.
.
i z Unless a certain measure or other is taken to obtain a flush ~urface 9 the conventional method is now no longer very appropriate in view of the situation prevailing today in the construction industry which calls for shorter construction terms, simpler work procedures and less cost. Moreover, as the demand for energy saving is giving a great impact on the architectural field, growing number of buildings and houses employ ~oaming plastics for insulation and for improving the air conditioning efficiency. As ~or insulation of walls9 methods are kno~n to interpose an insulating board made of foaming plastic~ such as foaming styrol at the time of ~allboard lining or to form an insulating layer on the spot after the wallboard is lined by injecting foaming plastics such as foaming uria resin and the like from openings perforated on the wallboard at desired places. The latter method whi¢h ~acilitates injection of insulating material on the spot i8 more preferred these days~ as compared with the ~ormer method which involves cutting of insulating boards to match the interval of the flurring strips and which entails storage of bulky insulating ma-terial and transporting the same to the construction spot. Even the latter on-the-spot foaming and filling method can not be considered perfect so long as the lathing i5 constructed by the conventional flurring strip method.
In the lathing of the conventional flurring strip method, the wall dy and the wallboard are continuously connected by flurring strips that are provided vertically and horizontally, so that 5~
even if the foaming plastics is filled in ~he interval between the wall and the wallboard, the insulating layer will not be formed where the flurring strips are provided. Also, the insulat-ing material will not be perfectly filled at the junctions o~
vertical and horizontal flurring strips which remain as voids without insulation, whereby the insulation of the wall at such port;ons becomes imperfect to cause linear or partial dew con-densation which may cause discolorings and soilings of the wall.
Su,mmar~ of the l~vention ~ he pre~ent invention has been developed in view of the drawbacks mentioned above with regard to the conventional method, and its primary object is to provide'a highly efficisnt and eas~
method ~or constructing lathing which has a flush sur~ace~
The second object of the present in~ention is to provide a novel oonstruction method of lathing which enables formation o~ an ideal insulating layer by providing a continuous space between the wall body and the wallboard and by injecting insulating material such as foaming plas~ics so as to provide unifo~m and:
continuous insulation.
The third object of the present invention is to provide a novel method for constructing lathing with the use of standard-ized and mass produced,.parts and which alleviates the carpenter's work on the spot.
Still further object of the present invention is to provide a novel method which facilitates construction of lathing having i42 a flush surface, even when the wall body ie made of roughly finished concrete with much irregularity on the surface, by simply adjusting the level of wallboard fixings and which entaiIs no special treatments or measures to achieve flat surface.
A method in accordance with the present invention comprises the steps of providing a plurality of plastic sleeve members each closed at one end and having an internal screw thread and a cooperating threaded bolt having a flat outer end engaging the screw thread, attaching the plastic sleeve members at predetermined spaced intervals to the wall body by fastening the closed end to the wall body so that the central axes of the sleeve members are substantially parallel; inserting the threaded bolts into the sleeve members and adjusting them so that the flat outer ends are substantially co-planar; support~ing a wallboard against the flat outer ends of the bolts in order ,.
to provide a space between the wallboard and the wall body, fastening the wallboard in position by nailing it to the flat outer ends of the bolts, drilling a plural~ity of holes through the wallboard between the sleeves and the bolts~ injecting foaming plastic insulating material of low in situ foaming pressure into the space between the wall body and the wallboard through~the holes to substantially completely fill the space, and plugging the holes~
In a construction in accordance with the present inven-tion, a fixing device for attaching flush wall lathing in spaced relationship to a wall body having an irregular surface comprises an elongated member to which the wall lathing is to be attached.
A plurality of holes are provided through the elongated member ~, .

The construction method of the wall iathing accGrding to -the present invention comprises, essentially, of the steps to provide the wallboard fixing means to the wall for adjusting their level, and to attach the wallboard thereto.
The characteristics of the present invention are best mani~ested when it is employed in the construction of lathing for the wall body made of roughly finished concrete. Fig. 1 illustrates the wall body (W) of roughly finished concrete with lots o~ irregularities on the surface and the plurality of wall board fixing means (1~ provided thereon. The ~ixing means are so arranged as to have a uni~o~m level of fixing by the revolution of the bolts (133, The fixing~means (1~ such as bolts and nut~
which comprises a sleeve (12~ on whose inner circumferential surface is cut a groove for female screw (11~ and a bolt (133 which engages with the said female screw (11) is usually e~ployed as shown in Fig. ~c The level o~ wallboard sur~ace can be adjusted by turning bolts (13~, The said fixing means is made of hard plastic material which can be nailed. The fixing means (1~ can be arranged on the wall body by nailing the sleeve (12) thereon, by using an adhesive agent, or by embedding the slee~es (12) in the concrete wall body in advance, When nailing the sleeve, the , ~:~2~SA~2 fixing means (1~ is attached to the wall body (W~ by driving nails for concrete from the inside bottom o~ the sleeve (12~ and by screwing a bolt (13) thereto. When an adhesive agent is used, the outside bottom o~ the sleeve (12~ i8 coated with ~he adhesive agent, and pressed again~t the predetermined spot on the wall (W) to securely fix the same and bolt (13) is screwed on. It is preferable to use a fixing means as shown in Fig~ 6 which has a fixing board (14) provided integrally at the bottom of the sleeve integrally therewith and which has knurling (1~ at the back o~
the fixing board (14) in view of the better adhesive force.
It is also possible to fix the said fixing board (14j with a nail (N)l as shown in Fig. 7.
As shown in Figr 8, a fixing means (1) o~ Fig. 9 is preferable when the sleeve (12) is to be embedded in the concrete wall body -(W)~ The flange (19) will thrust ~irmly in the~ooncrete wall body to prevent the sleeve ~rom coming off.
~ he adjustment of the surface level of the wallboard fixing means ~1) i9 conductèd with the use o~ a device such as 'Pplumb-bob" known in the art (not shown) so as to level the head of all the bol-ts (13) which act as the plane where the wallboard is to be fixed, ~ine adjustment being made with a driver (D) or the like, As the wallboard fixing means (1) have been arranged on the wall body"(W) and their level o~ fixing plane adjusted, the wallboard (2) i8 fiXQd to the fixing means 1, Fig. 2 shows the , ' ~
, . .
wallboard (2~ at ~his stage, An arbitrary number of openings (21~ may be provided on the wallboard ~2~ for injecting insulating material such as foaming plastics to construct ~n insulated wall.
The openings (21) ~or injecting insulating material may be provided on the wallboard (2) in advance or it is pussible to bore the holes with a drill after the wallboard has been set up.
As for the material of the wallboard, wood, plywood, gypsum t board and boards made of rock wool ~re suitable. ~he wallboard (2~ is sat up and fixed to the head of the bolt ~13~ of the ~ixing means (1) by a nail (N), thereby ~orming a space (I) between the wall body ~W) and the wallboard (2).
When foaming plastics or the like i3 injected at the construction site to fill the space (I~ between the wall (W) and the wall board (2) which has thus been constructed a~ the lathing~
to form an insulated wall, ~oaming plastics or the like i8 injected from the openings (21) bore on the wallboard ~2), and as shown in Pig. 3, an insulating layer (3) i8 formed in the space (I). As for the insulating material to be filled in the space (I), it is preferable to use foaming urea resin which imposes no pressure at the time of foaming. As said resin generates no pressure at time it is injected, it will not cause the wallboard to come o~
the wall or to warp by the pressure as in the case when foaming urethane resin is used. Moreover, since it has a good fluidityc it will uni~ormly and thoroughly fill the space (I) and leaves no void in the insulating layer (3). Foaming urea resin has a low ~LlZ~S4~
inflammability and even i~ it were to catch fire~ there would be hardly any toxic gas generated. It is far more advantageous, in view of the construct;on techniques and safety than any other foaming plastics.
When the injection of foaming plastics has been completed, the openings (21) of the wallboard (2) are filled with corking (43, and the wallboard is given a ~inishing trea-tment as shown in Fig. 4. In the embodiment shown in ~ig~ 4, the wall is ~inished by lining the wall with cloth. As for the material for corking (~), putty is generally used.
Fign ~ shows another embodiment of lathing construction according to -the present invention. This embodiment is characteri~ed in ~hat the base of the sleeves ~12) for the wallboard fixing means ~l) is embedded in the conorete wall (W) in advance at a pre-determined interval and that the bolts (13)~are screwed into these s1eeves (12) in order to arrange the level of~the wallboard ~ixing plane. It is advantageous, as has been described above, to use a wallboard fixing means ~l) which i6 provided with a flange (19 as shown in ~ig. 9.
~ ig, lO shows still another embodiment in accordance wi~h the present invention. ~he most characteristic feature o~ thi~
embodimen-t lies in that the wallboard whose back is provided with waterproof treatment (23) iæ used. By employing such a method, variolls inconveniences deriving from drying and shrinkage of the wallboard,especially rapid drying which occurs when foaming ~ 4 .
urea is used, ean be prevented, thereby effectively preventing cracks in the insulating layer (3), ~ igs. ll and 12 show still another embodiment of the present invention. ~he outstanding feature of this embodiment is that the wallboard ~ixing means (la~ has a base strip (16a) as ~hown in Fig. 12. In the figures, (lla~ denotes a female screws, (12a) slee~es, (13a) bolts, ~17a~ hexagon head for screwing, and (18a) pipe members ~or inserting nails, According to this embodimen~, a tubular sleeve ~12a~ having a male screw is attached t~ a long base strip (la~, and if the wallboard (27 is nailed with nail ~N~
and fixed to the wallboard (2), the nailing operation in the area equal to the area of the ba~e strip (la~ becomes possible, allowing a greater ~llowance as to the position o~ nailing of the wallboard (2~.
It is evident that nailing operation using the nail (N) for the wallboard (2) beoomes extremely easy as compared to the operation where the worker has to probe without actually se~ing the head of the bolts across the wall board (2), the area of the said head being quite small as shown in the embodiment o~ Figs~
lO and 11. What is more, a continuous space between the wall body and the wallboard (2? will prevents the occurence of disruption ~n the insulating layer.
.

In the lathing of the conventional flurring strip method, the wall dy and the wallboard are continuously connected by flurring strips that are provided vertically and horizontally, so that 5~
even if the foaming plastics is filled in ~he interval between the wall and the wallboard, the insulating layer will not be formed where the flurring strips are provided. Also, the insulat-ing material will not be perfectly filled at the junctions o~
