Abstract
A method of preparing lengths of metal channel (18) prior to their fixing against the shuttering for concrete work when constructing the reinforced concrete inner wall structure of a building. So that the lengths of channel can subsequently form a flush mounted and concrete free part of an adjustable bracket system by means of which a support plate or a number of support plates arranged end to end carry courses of bricks forming the outer skin of the building, or form part of other support apparatus, the method includes the step of pressing into place a length of resilient sealing strip (21) in a T-slot of a length of the metal channel (18), sealing the opposite ends of said metal channel, eg by end pieces 23, and securing the channel in position with its slotted but temporarily sealed side in contact with the shuttering. <IMAGE>
Description
Apparatus for use with cast-in channels for facade support and restraint apparatus.
The invention relates to apparatus for use with cast-in channels for supporting or restraining the brickwork or other facade forming the outer skin of a cavity wall in a building having a reinforced concrete inner wall structure.
Generally, in order to support the brickwork for example forming the outer skin of such a cavity wall, fixing elements such as fixing bolts or studs are secured in position when constructing the reinforced concrete inner wall structure. However, such fixing elements can never be exactly aligned horizontally and it is usual to provide adjustable bracket systems by means of which a support plate or a number of support plates arranged end to end, which are to carry the courses of bricks forming the outer skin, are capable of some limited vertical adjustment to compensate for any variations in alignment of the fixing elements.A part of such an adjustable bracket system may be a cast-in length of metal channel usually extending horizontally but sometimes extending vertically of the reinforced concrete inner wall structure. (If extending vertically of said wall structure, the length of metal channel may be provided with toothed serrations on inturned edges of flange portions which engage complementary serrations formed on the heads of bolts which engage the channels and can thereby be adjusted in increments of movement during the installation of the bracket system).
Heretofore, it has been usual to fill the T-slot of each length of metal channel with polystyrene foam material before the channels have been secured in position against the wooden shuttering defining the thickness of the inner concrete wall structure subsequently to be cast. In this way the T-slots have been kept free of concrete during the construction of the inner wall structure. However, the subsequent cleaning out of the T-slots before the T-bolts have been able to be entered into said slots has been a problem. The task is time consuming and, if the workmen decide to burn the polystyrene material with a flame gun, for example, is dangerous to health. The invention has for its object to at least alleviate the problem.
According to one aspect of the invention, there is provided a method of preparing lengths of metal channel prior to their fixing against the shuttering for concrete work when constructing the reinforced concrete inner wall structure of a building, so that the lengths of channel can subsequently form a flush mounted and concrete free part of an adjustable bracket system by means of which a support plate or a number of support plates arranged end to end can carry courses of bricks forming the outer skin of the building, or form part of other support apparatus, the method including the steps of pressing into place a length of resilient sealing strip in a T-slot of a length of the metal channel, sealing the opposite ends of said metal channel, and securing the channel in position with its slotted but temporarily sealed side in contact with the shuttering.
According to a further aspect of the invention, there is provided apparatus for use with lengths of metal channel which are to constitute cast-in channels for brickwork and other support or restraint apparatus, the apparatus being constituted by a length of sealing strip adapted to be resiliently retained in the T-slot of a length of the metal channel, and a plurality of end plugs by means of which the opposite ends of the lengths of channel are to be sealed. The apparatus may be used in combination with a plurality of clip elements by means of which the lengths of metal channel can be secured in position against the wooden shuttering.
In order that the invention may be fully understood and readily carried into effect, the same will now be described, by way of example only, with reference to the accompanying drawings, of which Figure 1 is a perspective view of a well known kind of brickwork support system,
Figure 2 is a perspective view within the wooden shuttering for forming a reinforced concrete inner wall structure of a building,
Figure 3 is a sectional view on the line 3-3 in
Figure 2,
Figure 4 is a perspective view illustrating the prior preparation of a length of channel section material before it is secured in position against the shuttering as shown in Figures 2 and 3, and
Figure 5 is a view showing the length of channel section material cast into an inner wall structure.
Referring now to Figure 1 of the drawings, the brickwork support system there illustrated is constituted by a horizontally extending support plate 10 and a number of brackets, generally indicated 12, secured to the support plate at intervals along its length. Courses of bricks which in the illustrated example are to constitute the outer skin of the cavity wall concerned are carried by the support plate. The brackets 12 are each capable of some limited vertical adjustment, relative to respective T-bolts 14 by means of which they are clamped in position against an inner wall structure, so that the support plate can be located in a horizontal position before bricklaying commences.
So that the brackets can be very quickly and easily fixed in position, the respective T-bolts 14 extend outwards from the T-slot 16 of a length of metal channel 18, the latter having been cast-in the reinforced concrete forming the inner wall structure during its construction. In other words, the length of metal channel has been secured to the wooden shuttering for the concrete work when constructing the reinforced concrete inner wall structure, the channel having been secured thereto with the open side of the T-slot in contact with the shuttering so that when the shuttering has subsequently been removed from the finished inner wall structure the T-slot has been accessible from the exterior wall surface.The channel is provided with a number of wavy plate elements 20, (only one of which is visible in Figure 1) welded to it to act as anchor elements in the reinforced concrete in which they will be set.
As shown in Figure 4, the lengths of metal channel have been prepared, prior to their fixing against the shuttering, so that their T-slots will remain concrete free throughout the subsequent pouring of the concrete. The method of preparation has included the step of pressing into place a length of resilient sealing strip 21 in the T-slot of each length of metal channel and the fitment of a pair of end plugs 23 in the opposite ends of each channel. The cross section of the sealing strip is substantially of H-section and can very easily be pressed into position by thumb pressure. When the reinforced concrete wall structure has set, the sealing strip can quite easily be removed as shown in Figure 5.
Thus there is provided a method of and means for preparing lengths of metal channel prior to their fixing against the shuttering for concrete work for the purpose described when constructing the reinforced concrete inner wall structure of a building. The use of a resilient sealing strip which can be pressed into position to seal the slotted side of each length of channel is a very great improvement on the use-of polystyrene foam material, partly because it is so very easy to remove to re-open the slot in a bare minimum of time and partly also because, since the workmen are no longer obliged to remove it by burning it the material does not constitute a health hazard.
Various modifications may be made. For example, the resilient sealing strip need not necessarily be of substantially H-section; other sections may be devised which are equally able to be pressed into position by thumb pressure but which are also equally capable of being removed when required to re-open the slot in the metal channel concerned.
The apparatus described above may be used in combination with a plurality of clip elements 22 by means of which the lengths of metal channel can be secured in position against the wooden shuttering.
Each clip element, as best shown in Figures 2 and 3, has a relatively thin section strap part 24 which connects much thicker root end portions 26 provided with nail holes 28. In use of the clips, their root end portions are fixed in position above and below the channel which is being secured in position. The channel is therefore held in position very securely indeed and the resilient sealing strip 21 is trapped in the T-slot of the length of channel by being clamped against the shuttering.
