Description:
This invention relates to the erection of temporary guard rails and is more particularly directed to demountable sockets for receiving guard rail posts.
This invention is an improvement on my copending application Ser. No. 817,951, filed on Apr. 21, 1969, for Demountable Sockets For Guard Rail Posts, wherein the sockets shown and described are provided with a bottom wall for supporting the posts and the tabs which are narrow serving only to fasten the socket to a cross member. It has been found that the use of these sockets on walers in pouring lintels failed to provide a secure seat for a post and also failed to reinforce the waler. The present invention avoids these disadvantages of the these sockets with longer front wall portions, wider tabs and removed the bottom wall to permit the post to extend beyond the lower portion of the socket.
Therefore, it is a principal object of the present invention to provide a guard rail post demountable socket that permits the post to extend beyond the lower portion thereof, thereby adding greater rigidity to the post.
Another object of the present invention is to provide a demountable socket for guard rail posts with an elongated front walls, and enlarged tabs so as to effect greater stability to a waler when fastened thereto prior to the pouring of a lintel and the like.
A still further object of the present invention is to provide a demountable socket which is formed and stamped in an economical fashion from sheet metal.
With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.
In the drawing:
FIG. 1 is a perspective view of a demountable socket for guard rail posts constructed in accordance with my invention.
FIG. 2 is a top plan view.
FIG. 3 is a rear elevational view.
FIG. 4 is a cross sectional view taken along the line 4--4 of FIG. 2.
FIG. 5 is a cross sectional view of a lintel showing my demountable socket fastened in position thereon.
Referring to the drawing wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to a demountable socket for guard rail posts 11 consisting of stamping formed from a sheet of material such as steel, aluminum and the like and shaped as indicated hereinafter to receive the post 11. The post socket 10 consists of a front wall 12 whose width is equal to that of the width of the post 11 but whose height is greater than the conventional sockets. Along each side edge of the front wall extends a side wall 13 at right angle thereto. The length of the side wall 13 is equal to the thickness of the post 11. Tab portions 14 and 15 are formed along the free side edges of the side walls 13 by cutting along the upper portion of the side walls 13 as at 16 from the top edge to a position removed from the bottom edge and bending the tabs 14, 15 as at 17 and 18 at right angles to the side walls 13 and to each other respectively. All of the walls 12, 13 and tabs 14 and 15 are provided with openings 20 for receiving fasteners such as nails and the like. As shown by FIG. 5 my demountable socket 10 is shown fastened by nails 25 to a waler 22 which extends along the upper edge portion of a form 23 for pouring a lintel 24. The socket 10 is placed along the side of the waler 22 with the tabs 15 resting on the top edge portions of the form 23 and waler 22. Nails 26 are hammered into the fan 23 and waler 22 through openings 20 on the horizontal tabs 15. The vertical tabs 14 which abut against the outer surface of the waler 22 are fastened there against by nails 25 extending through the openings 20 in the tabs 15. Then the post 11 is inserted into the socket formed by the front wall 12 and side walls 13 and permitted to slide beyond the lower portion thereof as shown by FIG. 5. The nails 27 are then hammered through openings 20 in the front wall 12 and nails 28 hammered through openings 20 in the side walls 13 to fasten the post 11 to the socket 10 to render the post exceptionally rigid and secure thereby. Any push or pull forces applied to the top end of the posts 11 will be resisted against movement by virtue of the post 11 extending below the socket 10 and abutting against the waler 22.
This invention is an improvement on my copending application Ser. No. 817,951, filed on Apr. 21, 1969, for Demountable Sockets For Guard Rail Posts, wherein the sockets shown and described are provided with a bottom wall for supporting the posts and the tabs which are narrow serving only to fasten the socket to a cross member. It has been found that the use of these sockets on walers in pouring lintels failed to provide a secure seat for a post and also failed to reinforce the waler. The present invention avoids these disadvantages of the these sockets with longer front wall portions, wider tabs and removed the bottom wall to permit the post to extend beyond the lower portion of the socket.
Therefore, it is a principal object of the present invention to provide a guard rail post demountable socket that permits the post to extend beyond the lower portion thereof, thereby adding greater rigidity to the post.
Another object of the present invention is to provide a demountable socket for guard rail posts with an elongated front walls, and enlarged tabs so as to effect greater stability to a waler when fastened thereto prior to the pouring of a lintel and the like.
A still further object of the present invention is to provide a demountable socket which is formed and stamped in an economical fashion from sheet metal.
With these and other objects in view, the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.
In the drawing:
FIG. 1 is a perspective view of a demountable socket for guard rail posts constructed in accordance with my invention.
FIG. 2 is a top plan view.
FIG. 3 is a rear elevational view.
FIG. 4 is a cross sectional view taken along the line 4--4 of FIG. 2.
FIG. 5 is a cross sectional view of a lintel showing my demountable socket fastened in position thereon.
Referring to the drawing wherein like numerals are used to designate similar parts throughout the several views, the numeral 10 refers to a demountable socket for guard rail posts 11 consisting of stamping formed from a sheet of material such as steel, aluminum and the like and shaped as indicated hereinafter to receive the post 11. The post socket 10 consists of a front wall 12 whose width is equal to that of the width of the post 11 but whose height is greater than the conventional sockets. Along each side edge of the front wall extends a side wall 13 at right angle thereto. The length of the side wall 13 is equal to the thickness of the post 11. Tab portions 14 and 15 are formed along the free side edges of the side walls 13 by cutting along the upper portion of the side walls 13 as at 16 from the top edge to a position removed from the bottom edge and bending the tabs 14, 15 as at 17 and 18 at right angles to the side walls 13 and to each other respectively. All of the walls 12, 13 and tabs 14 and 15 are provided with openings 20 for receiving fasteners such as nails and the like. As shown by FIG. 5 my demountable socket 10 is shown fastened by nails 25 to a waler 22 which extends along the upper edge portion of a form 23 for pouring a lintel 24. The socket 10 is placed along the side of the waler 22 with the tabs 15 resting on the top edge portions of the form 23 and waler 22. Nails 26 are hammered into the fan 23 and waler 22 through openings 20 on the horizontal tabs 15. The vertical tabs 14 which abut against the outer surface of the waler 22 are fastened there against by nails 25 extending through the openings 20 in the tabs 15. Then the post 11 is inserted into the socket formed by the front wall 12 and side walls 13 and permitted to slide beyond the lower portion thereof as shown by FIG. 5. The nails 27 are then hammered through openings 20 in the front wall 12 and nails 28 hammered through openings 20 in the side walls 13 to fasten the post 11 to the socket 10 to render the post exceptionally rigid and secure thereby. Any push or pull forces applied to the top end of the posts 11 will be resisted against movement by virtue of the post 11 extending below the socket 10 and abutting against the waler 22.
