That depends on the sise and the type of timber the floor boards are made of, However standard practice with flooring is 450mm centers or 600mm centers if the boards are thicker to allow for the extra 150 millimeter's
all depends how the floor is constructed and the size of the joists, the span of the joists, thickness of floorboards. Is it a concrete floor. Is it a 'live' load like people of furniture or a 'dead' load like an unsupported wall. It the house an old building or of recent construction. A residential standard suggests 40lb per square foot. Needs confirmation though
There would be more friction between the heavy wooden box and the floor than the light wooden box. This is because the friction force is directly proportional to the weight of the object pressing down on the surface, which in this case is the weight of the box. The heavier box would exert more pressure on the floor, resulting in greater friction.
If your house is wood framed with wood joists, the shaking may be caused by floor joists being too small. This will cause the floor to sink whenever a person walks across the room. Floor joists should be size by an experienced carpenter, architect, or engineer to prevent movement.Another cause of floor movement may be insufficient bracing between the floor joists. This will cause sagging and twisting of the joists.There are several solutions that require the skills carpenter. New joists can be added beside the existing joists to strengthen the floor. Another option is to add one or more beams and columns in the room below the floor. Or blocking can be added between existing joists to add support.
A ball would typically roll further on a wooden floor compared to a carpeted floor due to less friction between the ball and the surface on a wooden floor. The rough texture of the carpet creates more resistance, which slows down the movement of the ball.
A coir mat typically has more friction than a wooden floor because of its coarse texture and ability to grip onto shoes or feet. The friction generated by the coir mat can help prevent slipping and provide better traction compared to a smooth wooden floor.
That depends on how well supported the floor is and that depends on how far apart the joists are placed. The closer they are, the more weight can be supported.
I've never heard of there being any weight limit. I have put large tubs in a few mobiles and had no problem. Joists are 16" apart in the floor and can support a lot of weight.
To determine the number of 2x8 floor joists needed for a 12x16 floor, first calculate the area of the floor, which is 192 square feet (12 feet x 16 feet). Assuming the joists are spaced 16 inches apart on center, you will need about 12 joists running the 16-foot length (16 feet = 192 inches; 192 inches ÷ 16 inches = 12). Therefore, you will need approximately 12 joists to support the floor.
To locate floor joists in a room, you can use a stud finder or measure from a known reference point, such as a wall. Floor joists are typically spaced 16 or 24 inches apart, so measuring from a wall at one of these intervals can help you find them. You can also look for nails or screws in the floorboards, as they are often placed along the joists.
To lay out cross bridging in floor joists, first identify the spacing between the joists, typically 16 or 24 inches apart. Position the bridging diagonally between the joists, connecting them at their midpoints to provide lateral support. Use 1x3 or 1x4 lumber for the bridging, cutting it to fit snugly between the joists. Secure the bridging with nails or screws to ensure stability and reduce floor bounce.
The recommended type of support beam for floor joists in a residential construction project is typically a steel I-beam or a laminated veneer lumber (LVL) beam. These beams provide strong support for the floor joists and help distribute the weight of the structure evenly.
The thickness of subfloor needed generally depends on how far apart your floor joists are located. In most cases, floor joists are 16" center-to-center and the most common thickness of subfloor is 3/4". Some homes will have 1/2". If your floor joists are farther apart, you will need correspondingly thicker subfloor to adequately support weight between the wider joists. Your city's building codes department will be able to specify what you need (some cities may have differing requirements).Another factor might be the kind of flooring you will install. For carpet, vinyl, laminate, wood and other non-rigid flooring types, the 1/2" or 3/4" will be adequate. For tile, the Tile Institute of America recommends no less than 3/4" subfloor on 16" centers floor joists - but with 1/4" backerboard installed on top of subfloor. See their website or contact your city codes department for specifics on a different span of joists.
Different situations call for different joists. Generally floor joists are 2 x 12.
The recommended specifications for floor joists in a residential construction project typically include using lumber that is at least 2x8 inches in size, spaced no more than 16 inches apart. The joists should be properly supported and anchored to the foundation to ensure structural integrity and safety.
Common causes of sagging floor joists in a building include structural damage, excessive weight load, moisture damage, and poor construction. Solutions for sagging floor joists may involve reinforcing the joists with additional support beams, repairing or replacing damaged joists, addressing moisture issues, and ensuring proper construction techniques are used. Consulting a structural engineer or contractor is recommended for a professional assessment and appropriate solutions.
Sistering joists involves attaching new joists next to existing ones to increase strength. To effectively implement this, ensure the new joists are the same size and material as the existing ones, and securely attach them with nails or screws. This method can help distribute weight evenly and prevent sagging or weakening of the floor structure.
The recommended spacing for deck floor joists is typically 16 inches on center.
