Electrical junction boxes are metal or plastic housing to meet the electrical lines and link them together. The most common junction boxes measure 2-1/2 "to 3-1/2" deep and will be based on the number of wires connected. Boxes, which measure 2 "x 3" x 2-1/2 "have usually three wires, while the boxes, the 2" x 3 "x 3-1/2 measure to have" in the Rule 5 veins. Electrical junction boxes need to block a variety of support materials such as concrete are attached, or bricks. DifferentTypes of anchors are available, depending on the specific application and user settings. Most of the electrical junction box applications require that the concrete does not protrude into the lock box and have a finished or small head, to allow more space in the junction box and to remove a hook point for the electrical lines.
TAPCON – Concrete / cement screws
TAPCON concrete screws are often used for mounting a junction box for concrete, brick or block base material. Youare the most versatile type of real closure for this type of application because they work equally well regardless of the material, have consistent holding values and have a high success rate of installation. The hexagonal works best with their positive drive for installation and smaller head does not extend into the junction box. The TAPCON concrete screw is easily removed if necessary, and has excellent operating values in both the 3.16 "diameter and 1 / 4" diameter head style. The TAPCONConcrete screw anchoring requires a minimum depth of 1 and a maximum depth of 1-3/4 ". The screw length is the most commonly used for this application, the 1-1/4 "and 1-3/4" on either the 3 / 16 "diameter or 4.1" diameter. The head size on the 3.16 "diameter TAPCON is smaller than the 4.1" and can be a consideration in choosing the most appropriate closure. The 3.16 "diameter TAPCON requires a 4.1" driver and 4.1 "diameter requires a 16.5" driver. When installing aConcrete Screw, it is very important in order to select the proper size, as the bit-hole size and screw size tolerance are critical. The 3.16 "diameter concrete screws require a 5 / 32" hole and the 4.1 "diameter, a 3 / 16" diameter require. The hole must be drilled in the base material a minimum of 1 / 2 "deeper than the screw is the base material, leaving room for materials to pass through to go during the installation. TAPCON The screw is in concrete A 410 are available stainless steelStahl, in environments where corrosion can be used is a concern. Larger diameters or TAPCON LDT's are also in 3 / 8 ", ½", 8.5 available "and ¾" diameter for the larger, heavier junction boxes mounted on concrete, brick or block.
Wedge Anchor
The anchor bolts can only be used to attach a junction box on concrete. The most commonly used is the diameter of 4.1 "diameter. Large size wedge anchors up to 1-1/4" diameter for larger, heavier junctionApplications. The wedge is in the 4.1 Anchor diameter is available in three lengths of 1-3/4 ", 2-1/4" and 3-1/4 "and the minimal embedding (see second column in the table below) 1 -1 / 8 ". The length of the anchor must be chosen long enough for the anchor to be embedded in the concrete is at least 1-1/8", a 1-3/4 "length anchor bolts for fastening materials up to used 8.5 "thick, one 2-1/4" length anchor bolts for materials up to 1-1/8 ", uses a 3-1/4" length anchor bolt is used for up to 2-1/8 "thick haveMaterial. The longer the wedge anchor can be used for thinner materials. The embedding requires more drilling in concrete, but the operating gains as anchor bolts embedded deep into the concrete. A drawback to using the anchor bolts for attaching a junction box on concrete, that is set after the anchor bolt, the stud, and the mother can stick in the box and purchase valuable space and to a hook point for the wiring. Remember that the anchor bolts shouldfor use in concrete only, which means that it is not as versatile as some of the other concrete fasteners, such as the specific TAPCON screw or sleeve anchor.
Sleeve anchor
The sleeve is very versatile anchor for attaching junction boxes to concrete, brick or block and is used by many electrical contractor for this application. The design of the sleeve makes it particularly suitable anchor for the most basic materials, especially for material that is suspect on its ability to be attachedto. to anchor the most common diameter of the sleeve for mounting junction boxes on concrete, is brick or block the quarter. "The 4.1" diameter comes in a number of different lengths, depending on the thickness of the material is being tightened down or to the depth the embedding. There are two styles available head sleeve anchor: cap nut and round head. The nut is a small beveled nut which will allow for lower profile and avoid an edge for wire except snagged. The round headslit is the most popular, because the head has a very low profile and has minimal edge in the junction box. The acorn tip comes in three lengths: 8.5 ", 1-3/8" and 2-1/4 ". The round head is available in two lengths: 1-1/4" and 2 ".
Hammer Drive Anchor
Hammer drive anchors are suitable for mounting junction boxes to solid concrete, if a permanent attachment is required. The hammer-drive anchor is such that if the anchor has expanded the junction can not interpretedbe removed without risk of damage to the connector or without cutting the head from the anchor. The head-on style of hammer-drive anchor is ideal for this application for several reasons: It has a low, wide profile, it takes up little space in the junction, there is nothing on the wires to snare, it has a greater than normal support surface, and it has increased pull-over values. The hammer-drive anchor is available in two (2) Diameter: 3 / 16 "and 4.1". The 3.16 "diameter is not usedfor this application because its length is only 8.7 "which is not long enough at least to achieve integration. This is true also for the 4.3" Long 4.3 "Length Hammer Drive. The sizes for attachment to the junction boxes commonly used concrete are the 1 ", 1-1/4" and 1-1/2 "length Hammer Drive.
As with any Heimwerkermarkt or anchoring project, it is important that the security in mind and follow the instructions carefully. Remember to wear safety goggles, handle all tools with special care,and adhere to all technical specifications. This article is intended as a basic overview of the steps for the completion of this project. Always refer to the manufacturer or consult an expert authority. With a little research, planning and patience, you are now ready to expand your house or to create new space!
