Application April '1, 1932. Serial No. 603,843
s Claims.
This invention relates to concrete building blocks and particularly to a building block designed to support joists.
The general object of the invention is to pro- 5 vide a building block of concrete which may be laid the same as other building blocks but which is provided upon its inner face with pockets for the reception of the ends of the joists, the pockets being so formed as to receive what are known as character which is very strong, fire-proof, easily laid and which may be used in conjunction with 0 the bloc is shown and claimed in my pending application for patent, Serial No. 603,842, filed of even date herewith to provide for an air space ex' tending up through all the blocks.
A further object is to provide a concretejoist block in which the fioor of the joist receiving pockets is formed of a wooden strip laid upon the block below upon which the joists rest and to which the joists are nailed;
Other objects will appear in the course of the following description. 7
My invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a. face View of a rafter supporting block constructed in accordance with my invention;
Figure 2 is a vertical section through a wall showing the rafter block in place and a timber engaging in one of the pockets of the rafter block, the section being taken on the line 2-2 of Figure 1;
Figure 3 is a section on the line 33 of Figure 1. 7
Referring to the drawing, it will be seen that the joist block, generally speaking, is constructed in the same manner asthe block shown in my pending application above referred to, that is, there is an outer section 10 and an inner section 11 spaced from each other throughout their entire extent but having embedded therein the transversely extending metallic ties 12 which are preferably made of corrugated strips of metal having their ends apertured as at 13 to form a bond with the concrete. The outer face of the block 10 is formed by a slab 14 of terra-cotta, marble, ornamental stone or any other suitable material which will provide an ornamental face.
This portion 14, as will be seen from Figure .1, projects out beyond the body 10 in all directions. The body 10 is cut away upon its inner faceor reduced in thickness so that the ends of this por-;-
The section 11 has its face confronting the section 10 downwardly and forwardly inclined,
The inner face of the section 11 is'formed with a plurality of'pockets 15 which may be of any desired number depending upon the length of the block, these pockets being spaced from each other a distance of four inches on centers. rear wall 16 of each pocket starts from'a point below the upper edge or face of the section 11 and extends downward and forward to a point above the lower face of the section 11 and then extends straight downward as at 17. The lateral walls 18 which define these pockets 15 extend straight downward but terminate short'of the .lower edge face of the section llor, in other words, their lower edge faces 19 are disposed above the lower edge face of the block. The pur-- pose of so terminating the lateral walls 18 of the pockets is to provide for the insertion of a strip 19 of wood between the upper face of the next lower block or series of blocks and the ends of thejoists 20 so that the ends of the joists will rest upon the strip 27 and may be nailed thereto.
As shown the joists are what are known as fire cut joists, that is, their extremities are angularly cut so as to fit within the pockets 15, the lower edges of these angular portions of the joists resting upon the strip 19 and being nailed thereto as previously stated. Mortar or other bonding material designated 21 is disposed between the lower face of the section 10 and the upper face of the corresponding section of the block be-v'.
low as shown in Figure 2 and mortar is also disposed between the upper face of the block below and the lower face of the section 11, the strip 19 taking the place of this mortar as regards that portion of the section 11 which comes be-:
neath the pockets.
g It will be noted that the section 11 extends be true without regard to whether the block is made 16 inches, 20 inches or 24 inches in length. When an end joist block is used at one end of the wall, then the first two pockets of the series will be eliminated, that is, they will be closed by extending across said end wall and the joist will naturally fall into the next succeeding pocket which is the third from the left hand end of the block shown in Figure 1 and which is just past the middle of the block and, therefore, inside of the end wall. However, when the laying of the end joists is started at the opposite end of the building, the extreme left hand pocket in Figure 1 will be laid to the side face of the end block of the end wall as joist blocks are required in only two of the outside walls.
' A block of the character stated has beenfound in actual practice to be extremely strong and to resist all the stresses to which a wall blockof this character is subjected. The longitudinally corrugated strips 12 act to reinforce the two sections of the block, hold them in spaced relation and resist all deformation stresses.-
The portion 14, as before stated, may be made of terfzt-cotta, marble or other ornamental stone or have any other desired ornamental character or finish and inasmuch as this portion 14 projects beyond the edges of the section 10, anarrow joint may be made on the outer face of the wall between the blocks or between the portions 14 while a full mortar joint may be providedat .21 between the edge faces of the section 10 and the edge faces of the nextadjacent blocks and the same is true of the section 11. 7
Where the joistsupporting blocks rest upon the foundation, of course, a full mortar joist will be provided beneath the lower end of the sec tion 11 but where the joist blocks are used above the foundation, then a course of blocksA will be used constructed in accordance with my other application for patent herewith referred to but in which the rear section 11a is increased in width so that it is equal in width at its 'top'to the width of the section 11 of the joist block at its bottom, thus providing for a mortar joint 21a of suflicient size. 1
I claim:-
1. A concrete joist block having pockets upon its inner face, the rear wall of the'pockets extending downward and inward, the pockets being open at their lower ends, the; walls defining the sides of the pockets terminating above the lower face of .the blocks whereby a wooden strip may be disposed on the wall below to form the lower wall of the pockets and support the ends of the joists and permit the joists to be nailed thereto.
2. A concrete joist block having upon its inner face a plurality of joist pockets spaced at uniform distances from each other, the width of a pocket, the joist pocket at one end of the block being of full width but opening upon the end .face of the block, the joist pocket at the opposite end of the block being spaced a full width of a pocket fromthe adjacent end face of the block.
3. A concrete joist block formed of two sections'spaced from each other over their entire extent, rigid metallic ties embedded in the two sections of the block and holding them in spaced relation to each other, the inner face of the inner section being formed with a plurality of joist pockets, the rear walls of the pockets extending downward and inward and the pockets being open. at their lower ends, the walls defining the faces of the blocks whereby to permit a Wooden strip to be disposed on the wall below to form" the lower wall of the pockets and support th ends of the joists.
4..In a wall, a lower course of blocks and an upper course of joist blocks, the joist blocks upon the extending downward and inward and beingopen at their lower ends, the lateral walls defining the sides of the pockets terminating above the lower faces of the joist blocks, a wooden strip disposed between, the lower course of blocks and the lower ends of the walls of the pockets, mortar disposed between the lower course of blocks and the lower faces of the joist blocks, and joists having their ends fitted within the pockets and resting upon said strip and nailed thereto.
5. A concrete joist block having upon its inner face a plurality of joist pockets spaced at uniforin=distances from each other, the width of a inner faces being formed to provide a plu-" "rality of uniformly spaced pockets, the pockets pocket, one end of the block having a joist pocket c the full width but open on its side to the end face of the block, the joist pocket at the opposite end of the block being spaced a full width of a pocket from the adjacent end face of the block.
