Description

WIRE LOOP BOX
The invention relates to a wire loop box used in after-cast seams between concrete wall elements and between other reinforced concrete elements, which includes a housing to be mounted on the seam and a wire loop to be attached to the housing. The wire loop boxes are used at construction sites in after-cast seams between reinforced concrete wall elements and other reinforced concrete elements. The wire loop boxes with their housing constitute concrete wire loop box reinforcement and a loop reinforcement in the cast seams of the concrete elements, which supports the structure and increases the seam's durability. It is known before to use wire loop reinforcements bended from concrete reinforcing bars or wooden or metal dowel moulds. In addition, dowel loops and sheet steel housing or dowel loops and recyclable plastic housing and plastic installation components are used, by which the length of the wire loop is adjusted when using a plastic or steel housing. Such reinforcement methods include a variety of disadvantages.
When using loop reinforcements bended from concrete reinforcing bars, the preparation, installation and demolishing of the element moulds require a lot of work. Furthermore, the quality of the loop reinforcements varies and may be inappropriate for seam casting. When a separate plastic installation component is used, by which the length of the wire loop is adjusted, the installation work consists of several stages and it is complex, which increases the working time. Furthermore, it is difficult to control the grip length of the dowel loop, especially when using a plastic housing.
The objective of the invention is to provide a wire loop box, by which the drawback associated with currently used dowel loops are eliminated. Especially the objective of the invention is to provide a wire loop box with a simple structure and no separate components that is easy to handle. Furthermore, the objective of the invention is to provide a wire loop box which can be easily and simply mounted on a mould, and during the use it will enable an easy detection of the wire grip length, the wire will not reach the mould during installation nor move in relation to the housing during casting, and the housing will excellently stay in place inside the concrete.
The objective of the invention is provided with a wire loop box, which is characterised by what is presented in the claims. In a wire loop box according to the invention, the grip loop has been inverted into the housing during the manufacturing stage and it is set to be turned out during the installation stage. In that case, the finished wire loop box can be easily transported to the construction site and easily set in place. The grip loop is turned out from the housing during the element installation stage, and it will then be ready for casting. The wire loop box according to invention has a simple structure; there are no detachable additional components, or recyclable and components requiring additional work. Installing it into a mould is a very simple and fast procedure.
In an advantageous application of the invention, the housing includes perforation for fastening the wire loop, and the perforated holes are at different points in different housing types. When the housings are of the same size, wires of the same length are used to create the loop, and the perforated holes are at a certain point in a certain housing type, this housing type will have grip loops and free loop sections of a certain size. Similarly, when the perforated holes in another housing type are at a different point, the grip loop and free loop sections in this type are of a certain size, but different from the first housing type. Thus, the housing (= housing perforation / internal dimensions) define the length of the section to be cast into the wire loop box element / after-cast into the seam. The perforated holes on the housing for the wire loop automatically define the wire loop box type. The types include, for example, wire loop boxes of 80, 100 and 120 mm. Furthermore, each housing includes a die cut type ID - 80, 100 or 120 - which means that it is easy to see the length of the wire loop box's wire loop and free section. This provides simple detection of the wire loop box's grip length.
In advantageous application of the invention, the sidewalls of the housing are bended into a diagonal position. This provides excellent grip of the housing in the concrete due to its edge form.
In another advantageous application of the invention, the fastening sleeve for the straight parts of the box is a hexagonal wire loop compression sleeve that is the best possible alternative in terms of tensile stress. The invention will next be described in more detail with reference to the accompanied drawings, in which
Figure 1 shows a diagonal front view of one application of the wire loop box in accordance with the invention, and Figures 2—4 show top views of the different applications in accordance with the invention seen from above the housing and the wire loop shown as a dotted line,
Figure 5 shows a side view of one housing in accordance with the invention.
The wire loop box in accordance with the figures includes a bended housing manufactured from sheet steel or another applicable material 1 and a wire loop 2 threaded through the housing, manufactured from high strength steel. The housing is manufactured by mechanical cutting and bending. The sidewalls 7 of the housing are bended into a diagonal position. The wire loop 2 is threaded through the holes 6 perforated on the housing in such a manner that the grip loop 3 will remain inside the housing and the free ends of the wire, i.e., the straight parts 4 of the loop are connected to each other with the anchoring hexagonal compression sleeve 5. The wire loop is placed inside the housing by bending the grip loop 3 inside the housing and protecting the open part of the housing from cast burrs with tape. Figures 2—4 show housings of different types. The housings 1 are of the same size and form. The perforated holes for the wire loop are in different places in the different housings shown in the figures. In the housing shown in Figure 2, the holes are close to the housing end; in the housing shown in Figure 3, the holes are farther away from the housing end; and in the housing in Figure 4, the holes are even further away from the housing end. The grip loop 3 is shown as a dotted line in the figures, and it extends close to the housing's opposite end in each housing type. Thus, the housing shown in Figure 2 includes the largest grip loop inside the housing, the grip loop inside the housing in Figure 4 is the smallest and the grip loop inside the housing in Figure 3 is average size. Since the wire loop length is standardised, the lengths of the free sections outside the housing are the opposite: shortest in case of Figure 2 and longest in case of Figure 4.
Installation of the wire loop boxes in accordance with the invention is as follows:
The required wire loop box is selected in accordance with the seam width used. The required concrete strength and the spacing between the wire loop boxes are determined based on the shear force given in the structural designs.
The wire loop boxes are installed on a mould by driving nails through the perforated holes on the housing. The bendable steel wire is installed in between element reinforcing bars. The cable wire need not be fixed onto the reinforcing bars. When installing the wire loop boxes, the concrete cover requirements included in the concrete standards must be followed.
The protective tapes are removed from the housing before installation onsite. The grip loops are turned out from the housing before element installation. The grip loops can be turned out of the housing without any tools. The wire loop boxes are placed in a normal manner in the element, symmetrically in relation to the seam
(horizontally). When element installation is completed, a seam reinforcement bar is mounted through all the loops. After this, seam grouting will be performed using the grouting concrete in accordance with the structural design; the recommended minimum strength is the same as for the element.
The wire loop boxes constitute the concrete dowelling and loop reinforcement in concrete element construction joints. The wire loop boxes are installed in an element with the division determined by a structural engineer. The pliable wire loops can endure several times of bending and thus enable successful element installation without breaking the concrete even with close spacing.
The invention is not limited to the described applications; instead, it can vary within the scope of the inventive idea presented in the claims.
