CEMENT WALL CONSTRUCTION.
Application led October 20, 1924. Serial No. 744,656.
My invention relates to improvements in cement wall construction wherein a hollow core is permanently embedded within cement poured into a suitable wall formed to provide a continuous air space between spaced inner andouter wall portions.
- As is well known, a double wall consisting of inner and outer wall portions separated by an air space is highly desirable because of its heat insulating properties and the effectiveness with which such a structure prevents moisture from penetrating through the wall. Such double wall structure is accomplished in numerous ways in the case of wooden and brick construction, but heretofore no fully Satisfactory or commercially practical means has been devised for constructing such a double wall from cement or concrete, cement walls commonly vbeing made solid or else built up from hollow blocks.
In cement block construction, the blocks are constructed with heavy webs formed at frequent intervals between the inner and outer wall portions and as a result `the insulation alforded by the air spaces is of but slight benefit and moisture readily penetrates through the webs to the inner side of the wall. Furthermore, the blocks are bulky and top heavy so that the building of a wall from such blocks is a slow and relatively eX- pensive means of construction. i
The solid cement wall, formed by pouring cement directly into built up wall forms of suitable character is of course cheaper than the cement block construction, but the advantages of a hollow wall construction are entirely lost.
In the case of a cement wall, a. double wall construction wherein the inner and outer wall portions are completely separated by afcontinuous air space is practically advantageous as a finishing coat of plaster may be applied directly upon the inner surface of the inner wall without the use of lath or furring and without danger of injury due' to the penetration of moisture through the wall. y
My invention therefore has, as its primary object the providing of an .improved construction to obtain a double cement wall, the inner and outer portions of which are fully separated by an air space.
.Another object of my invention is to provide an improved Wall construction which can be constructed economically and which will further reduce the cost of a building by permitting the wall to be surfacedv directly upon the surface of the Wall Without the use of lath or furring.
A further obj ect is to provide an improved core Which may be readily mounted within a wall form and adapted to be permanently embedded to form a continuous air passage between the inner and outer wall portions formed when th-e form is filled.
A still further object is to provide an improved insulating vcore built in sections which may be readily assembled and which will insure acorrect matching of adjacent edges of adjacent sections.
A further object is to provide an improved core provided with means for retaining the wall of the core and of the form in properly spaced relation and which will serve to bond together the inner and outer wall portions of a cement wall.
A still further object is to provide an improved core which may be -economically manufactured and which can be permanently embedded within a cement wall to aord an improved wall construction at a very low cost.
Iaccomplish these and other objects by means of the improved wall construction disv closed in the drawings forming a part of` the present specification wherein like characters of reference are Vused to designate similar parts throughout said specification and drawings and in which,
Fig. l is a broken elevation of'a portion of a wall constructed in accordance with any invention, portions being broken away toV wall having a hollow core, designated in general by the numeral 3, forming a. continuous air passage therebetween.
The core 3 is formed from a plurality of sections each consisting of a pair of walls held in parallel spaced relation by meansl of spacing elements 4L mounted therebetween. saids walls being rectangular in form and made from any suitable material such as light wall-board- The spacing` elements 4 consist of strips of wood or wall board of suitable width to obtain the desired spacing between the walls, said strips extending outwardly. past the edges ofthewalls for a purpose hereinafter more fully explained.
The walliis constructedrby building` a-suitable form 6 in the manner commonly employed in the building of solid cement walls, the core 3 being mounted between the sides of the form by assembling the core sections together as the form is erected. Spacers 7 are applied in connection with the core sectionsto holdthe sections in a desired position between the walls of the form and to hold the sides of the form in a desired spaced relation, thesidesof said form beingI drawn against the ends of the spacers in the well known manner to obtain' a uniform spacing of the form.
Inl assembling the core 3 the sections are placed with their ends andy sides abutting against the adjacent ends or sides of adjacent' sections. The sections are preferably staggered and the outwardly extending ends of the spacing'strips ilcaused to enter between the adjacent wall po-rtions of an adjacent section as shown in F ig.- lof the drawings, thereby'insuring an accurate matchingv of the walls and holding the sections in assembled relation. Ati the corners of a building,- the core 3 ofv one wall 'is caused to abut against the core of the wall at right angles thereto as showninFig. 2'of`the drawings whereby the core is extended without interruption around the corner.
After the form and core have been built, wet cement is-poured in the ordinary manner to fill the spaces between the core-and the sidesA of the form, the core beingl fully embedded inthepoured cement and forming a continuous airpassage between the inner and outer portions of the wall. The spacing elementsa are spaced at intervalsA of from three to six inches, depending-upon the weight of material used to form thewalls of the sections 3, said spacing elements being arranged suhciently close together to sustainthe weight of the cement and prevent the collapse ofthe core when the form is filled. The spacers 7 are embedded within the cemen't'uponv both sides ofthe core as the form is filled.
`When the cement has-become set, the wall form 6 is taken down as in ordinary practice, the core 3 beingcleft embedded within the center of the wall. After the form has been removed the wall portions stand as a self sustaining structure presenting the outward appearance of the ordinary solid cement wall but provided with a continuous air space between said portions, the inner and outer wall portions l and 2 being effectively bonde'd together by means of the spacers 7, the ends of which are permanently embedded within the cement in opposite wall sections.
ln my present` practice, the coresections 3 are constructed ofv relatively light weight card-board. This material is relatively cheapl thus permitting the sections to be manufactured at a very low cost whereby the core may be permanently embedded within 'the wall at a cost little, if any, greater than the cost of a solid wall of the same dimension. After the cement has set it is immaterial whether the core disintegrates or not, thus making the selection of a durableorA rot resisting material unnecessary.
lhe above described wall structure is particularly adapted for the building 'of homes and cottages. In this connection, the double cement wall formed is adapted to receive an interior iinishing coat of plaster applied directly upon the cement without theexpense of applying lath or furring of any kind; rlhis is rendered possible as the heat insulation obtained by the double wall structure avoids subjecting the plaster to stressdue to Iexpansion and contraction resulting from changes in temperature, and also prevents absorption of moisture through the wall such as would tend to loosen the plaster.. In like manner a iinishing 'dash coat of stucco or other suitable finishing material may be applied directly upon the outer surface of the wall without the use of lath or furring. In this manner a very great saving may be effected in the cost of construction and at the same time obtain a lighter and' warmer house.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is,
l. A hollow core for a cement wall consisting of a plurality of core sections each having a pair. of walls formed from vlight wall-board andprovided with a plurality of spacing elements secured between said walls' to hold the saine in spaced parallel relation, the ends of said spacing elements extendingy outwardly pasty the edges of the walls to'be engaged between the walls of adjacenty sections whereby said sections may be assembled and held with the edges ofeach section matching with the adjacent sections.
2. A hollow core for a cement' wall consisting of a plurality of core sections each having a pair of walls formed from light wall-board and provided with-a plurality of spacing elements securedbetween saidwalls to hold the same in spaced parallel relation, the ends of said spacing elements extending outwardly past the edges of the walls to be engaged between the Walls of adjacent sections whereby said sections may be assembled and held with the edges of each section matching' with the adjacent edges of adjacent sections; and means for holding the core in spaced relation tothe sides of a wall form whereby the core maybe enclosed within the 10 Wall when cement is poured into the form.
In witness whereof I hereunto set my sig- HENRY M. STEARNS.
