Building wall layout tool

Description

This invention relates to laying out location of walls of buildings under construction and for positioning plumbing, electrical, air-conditioning, sewage and other conduits in relationship to the walls prior to pouring concrete slabs for the buildings.

A wide variety of batter boards and structural positioning tools are known for positioning walls and for positioning plumbing, electrical air-conditioning, sewage and other conduits in relationship to the walls of buildings prior to pouring concrete slabs and footers for the buildings. There are none, however, which have convenient two-way handles, wall-side-line adjusters, height adjusters and other advantages as taught by this invention.

Listed below for consideration is known related prior art:

SUMMARY OF THE INVENTION

Objects of patentable novelty and utility taught by this invention include providing:

• • line holders which can be positioned conveniently and accurately in ground proximate intended walls and conduits of buildings;
  • convenient, quick and accurate positioning of indicator lines on the line holders for indicating opposite sides of walls intermediate pairs of the line holders;
  • holder spikes that can be driven easily into, hold fast in and be removed easily from ground having foreseeable consistencies proximate building sites;
  • height adjusters that allow convenient adjustment of height of the line holders as may be helpful for progressive stages of construction; and
  • a building-wall-layout tool which is sufficiently advantageous and convenient for overcoming inaccuracy of makeshift and time-consuming use of batter boards which traditionally have been scrap boards battered into the ground proximate intended walls and then tying string between the batter boards to indicate where to position water, electrical, gas and sewage conduits in positional relationship to the intended walls.

This invention accomplishes these and other objectives with a building-wall-layout tool having a pair of two line holders, each of which have spike legs for being driven into ground proximate opposite sides of an intended wall section of an intended concrete slab for an intended building. Each of the line holders include a fastener section and a handle section. The fastener section includes a fastener slot extended from proximate a first side to proximate a second side of the fastener section. The fastener slot is articulated for receiving at least two line fasteners which are articulated for being slid in the fastener slot and affixed removably to sides of the fastener slot selectively intermediate the first side and the second side of the fastener section. The line fasteners are articulated for receiving and retaining indicator line designedly. The first side of each of the line holders includes a first spike aperture having a spike fastener for receiving a first spike leg and for fastening and unfastening the first spike leg at desired positioning in the first spike aperture. The second side of each of the line holders includes a second spike aperture having a spike fastener for receiving a second spike leg and for fastening and unfastening the second spike leg at desired positioning in the second spike aperture.

The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.

The fastener section 2 and the handle section 3 are preferably made of a predeterminedly durable plastic.

As shown in FIG. 4, metal lining 26 can be provided on surfaces of the fastener slot 6 for aiding durability with sliding contact of the first line fastener 7 and the second line fastener 8 with the edges of the fastener slot 6.

As shown in FIG. 5, a secondary support system having at least one secondary support sleeve 27 attached to the line holder 1 for retaining a support stake 28 can be provided for extra support in ground material 13 that is unusually soft.

The line holder 1 has a preferable width of sixteen inches intermediate the first side 4 and the second side 5.

Referring to FIGS. 1-13 for description of operative use, a pair 29 of two line holders, a first line holder 30 and a second line holder 31, each include the fastener section 2 and the handle section 3 which are separated predeterminedly intermediate proximate the first side 4 and the second side 5 of the line holder 1. The fastener section 2 has the fastener slot 6 extended from predeterminedly proximate a first side to proximate a second side of the fastener section 2.
