Is Your Home Really Safe-yuanjiao

Home-Securtiy A home invasion is basically a robbery that occurs when you and your family are at home. Since the majority of people do not arm their alarm systems when they are active in their homes, thieves or assailants know that they can take as much time as they want once they have broken into your home. Less than three Kicks and one minute is all it takes to break through the average residential door secured with a deadbolt. That is why thieves kick in doors to gain entry in more than 50% of all home burglaries. Home invasion is frightening when you consider that your family (as well as your possessions) is the target. More frightening still is the fact that occurrences of home invasions are on the rise. The FBI says every 12 seconds a home is invaded by going right through the front or back door. In 2005, law enforcement agencies reported an estimated 2,154,126 burglary offenses a 0.5-percent increase .pared with 2004 data. Burglary accounted for 21.2 percent of the estimated number of property crimes .mitted in 2005. Of all burglary offenses in 2005, 65.8 percent were residential structures. Most (62.4 percent) of residential burglaries in 2005 for which time of occurrence was known took place during the day, between 6 a.m. and 6 p.m. Many people believe that a home security system, with offsite monitoring, is all they need to keep their home secure. An alarm system will not stop an intruder that has made the decision to enter your home. The national police response time for a home alarm is approximately twenty minutes…An experienced thief will be in and out of your home in three to five minutes. However, you must realize that: The function of an alarm system is to alert you that someone has already entered your home. There’s one inch of soft wood protecting the safety of your home. Open your front door and look at the dead bolt plate. There is one inch of soft wood protecting the safety of your home. Your door casing can not protect you from a thief kicking in your door. The door frame is often referred to as the door jamb, and it is inherently weak. In most cases, the door frame is the weakest part of the door assembly. Door frames are usually constructed of soft wood and offer little or no resistance to splitting. The most important point of any door security system is the place where the deadbolt lock meets the frame. The Door Jamb- A door jamb is the vertical section of a door frame, which acts as a support for the remainder of the frame, as well as the door itself. Each frame has two jambs. The hinge jamb is the side where the hinges are installed, and the strike jamb is the side where the locking mechanism latches into the strike. The jambs are also used to mount the frame to the surrounding wall. The horizontal member that connects the two jambs is called the head. The material used to make a door jamb is largely determined by where it will be used. In most residential settings, the door frame is made of wood. It is typically hidden by trim, so the type and finish of the wood is generally not important. For .mercial uses, hollow metal door jambs are most .mon, and are made of cold-rolled steel for interior applications, or galvanized steel for exterior use. Some architects may specify frames made of stainless steel or aluminum to provide a nicer finish, while fiberglass frames are used for their durability and weather-resistance. There are a number of .ponents that go into making up a door jamb. There is the face of the jamb, which is the surface that is parallel to the wall. The stop of the jamb is the bump-out that holds the door in place and keeps it from swinging straight through the frame. On either side of the stop is an area known as a rabbet. The majority of door jambs .e equipped with one rabbet larger than the other, meaning that the stop is not centered, though equal-rabbet frames can be custom-made. When ordering a door frame, several details about the jambs must be determined, starting with the throat size of the jamb. The throat is the back portion of the door jamb that wraps around a wall for installation. It should be equal to the thickness of the wall where it is being installed. Next, one must specify the types of hardware to be used. Each door jamb will then be prepped with cut-outs or reinforced with steel plates to ac.modate and support the hardware installation. A variety of fasteners are used to secure the door jambs to the adjacent walls. With wood frames, most types of nails and screws are acceptable. Metal frames require specialty anchors, and generally these anchors must be ordered with the frame. For masonry walls, a T-anchor or wire anchor is welded into the jamb, then set between the layers of brick or block. A .pression anchor is welded into the jamb of frames used in drywall, and can be adjusted to fit the walls after they are erected. About the Author: 相关的主题文章:
