Definitions

  • This invention relates to an improved steel soldier for supporting concrete formwork and represents an improvement or modification of the steel soldiers which have been disclosed in British Patent Specifications 1551154 and 2145145.
  • Those soldiers are of a kind which comprise a pair of elongated steel elements, which may be of channel section, connected back to back and parallel with one another.
  • Each element has a web which, in order to minimise weight, has openings spaced at regular intervals along its length. To increase the stability of these webs the openings have peripheral lips otherwise known, and hereinafter referred to, as flanges. Further the flanges of the respective web may be flared as appropriate in opposite directions.
  • the present invention has been devised with the general object of providing a soldier which has an increased shear and bearing load carrying capacity. above that of a flange which is turned through 90°.
  • the flanges of the respective webs face in opposite directions preferably with the channels facing one other.
  • the soldier therein shown comprises a pair of beam elements each comprising a folded steel plate having a flat web 1 formed with elliptical openings la along its length. Three such openings are shown although there may be more depending upon the overall length of the soldier. In each instance however dimension D h may be less than dimension D v (as illustrated) or greater than or equal thereto.
  • the web 1 is laterally extended so as to enter and give support to a pair of hollow profile chord plates 2 of somewhat channel-shaped configuration which are attached to the web by welding at locations a and b along the web edge and one web face.
  • the complete soldier is comprised of two beam elements as above described mounted in parallel opposite facing spaced relation and connected at their ends by rectangular tie plates 3. Also depending upon their length they may be connected intermediate their ends by one or more diaphragms (not shown).
  • the openings la in the webs have been formed at their peripheries with lips or flanges lb which have a simple arcuate profile but in accordance with the invention the peripheral portions of the openings are formed with lips or flanges lc of U-shaped profile as shown in Figs. 3 and 5(a).
  • Figs. 5(a) and 5(b) the dashed lines indicate the mode of elastic settlement of the newly devised flanges lc and the previous flanges lb under the same applied load P 2 .
  • Fig. 5(a) e 1 represents the lateral distance between the planes of the points of application of the load P 2 whilst in Fi g. 5(b) e 2 represents the equivalent distance for the previously used arcuate flange configuration.
  • Fig. 6 diagramatically represents the distribution of loads in the region of a web opening la of the improved soldier when a bearing tube is supported therein and sheds a load in the direction indicated by arrows P. Due to the lesser value of e 1 compared to e 2 the channel shaped flange profile acts more as a hoop. This enables components R c of reaction R, R, to be carried within the circumference of the flange section, thus reducing the stress intensity.
