How to draw wall anchors and show wall height?

Question

Can somebody please show me a picture of how I can show wall height in an architect's drawing of a floor plan (for new wall construction). Also, I need to see what the drawing of "how the wall is anchored" looks like. Thanks much.

Answer 1

In an architectural drawing the vertical heights are shown in a separate drawing: elevations (taken at 90 degrees to the plan drawing as if directly facing the wall).

Anchor bolts are used to tie concrete, brick or concrete brick walls together. The most common use is to tie the building's walls to the foundation through the sole plate. The sole plate is anchored to the foundation floor.

The floor plan is the master drawing and all other drawings refer to it. On the floor plan you would draw the position of the anchor bolts on the floor plan. Look the step 1 drawing for a floor plan example: http://www.preengineeredsteelbuildings.net/page4.html for an example.

An elevation drawing is referred to on the floor plan by using large block arrows to denote the direction the person would be facing to get the viewpoint. Typically you would label that arrow as Elevation A and so on. It is customary for a complete set of plans to include elevations for each and ever wall (usually drawn from the inside looking out). Here window and wall heights as well as things like cabinetry would be shown.

If you want a drawing to show the typical method for anchoring the wall then that is a detail drawing (sometimes called a shop drawing). Again the detail is noted on the floor plan, this time with a circle around the area with the detail then the detail drawing would be noted. Normally the details and elevations are drawn on their own separate pages so it is customary to label the detail or elevation call out with the page number where the drawings can be found.

On this page: http://www.brickinfo.org/BIA/technotes/t44.htm
figure 4 is an example of a detail drawing. On this drawing the specifics for the anchor bolts (dimensions, type etc.) would be called out and a reference to the drawings specifications may be made to tie those type written documents to the drawings. Figure 7 shows anchor bolt details on the floor. Figure 17 shows how to do a detail drawing from a detail drawing and the same method would be used for the floor plan call out.

Here is an isometric drawing showing wall anchors: http://www.reddiform.com/pdfs/CADDrawings/Installation_of_Joists_Using_Anchor_Bolts.pdf (Item B are the anchor bolts). Isometric drawings are not common because they are not normally dimensioned, but they can be included to show a detail better.

Hilti is a manufacturer that creates tools to place anchor bolts and they included AutoCAD drawings on this page: http://www.us.hilti.com/holus/modules/techlib/teli_main.jsp?BV_UseBVCookie=no&BV_SessionID=@@@@0864523559.1198985529@@@@&BV_EngineID=cccdaddmlffmlkkcefeceeedfkldfhg.0 (You need a CAD program that can read DWG files to see the drawings).

Here is a section view, which is a view that cuts throgh the wall (http://www.blueprintforsafety.org/documents/01.pdf). Again you would note the section on the floor plan, usually with a line through the wall and two arrows that go 90 degrees to that line to show the direction of the point of view. Sections are normally denoted AA, BB, CC...

Answer 2

You could show it as a 3 d or iso drawing, possible with dotted lines within the wall. you could do a section in the drawing noting to a corresponding letter/number to an inset in the print. such as "a-a" with a small 3 d, making the female part to your anchor in the wall drawing. Hope that doesn't confuse you...
