Abstract: Certain types of interior concrete masonry block and stud wall constructions, and blocks for making the same, so as to provide improved thermal storage properties, improved heating and cooling and other advantages are disclosed. A preferred embodiment relates to modification of conventional interior lightweight stud wall construction systems which are in wide spread use and typically comprise lumber or steel stud framing covered by wall board with or without insulation installed within the wall. In such embodiment disclosed concrete masonry blocks are used as part of the wall by mounting the blocks between the studs and wall board. The concrete masonry blocks provide thermal storage capabilities so that the walls thus constructed store heat whereby temperature swings are attenuated and heating and/or cooling cycles are spaced at longer intervals to achieve more comfortable temperature conditions with resultant energy savings also.

Abstract: A prestressing anchor is embedded in concrete in part of a concrete structural component, and after setting of the concrete, a prestressing element extending through the prestressing anchor is prestressed and held by clamping wedges disposed in a frustoconical portion of a passage running through the prestressing anchor. Thereafter, a spacer element and an associated or integral further prestressing anchor provided with clamping wedges are pulled onto the prestressing element. With the aid of screws passing through flanges of the prestressing anchors, the further prestressing anchor is held to the first prestressing anchor, the spacer element resting snugly against the end faces of the clamping wedges. The second phase of construction is then carried out, at which time the further prestressing anchor is also embedded in concrete. After setting of the concrete, the following section of the prestressing element is prestressed to about the same value as the preceding section.

Abstract: An access floor panel construction employing peripheral trim channel elements joined together at the panel corners and fixed at their mid-lengths to the edges of a main body. As disclosed, the trim elements are of an organic thermoplastic material and are ultrasonically welded together at their ends and thermoplastically deformed into receiving portions of the main body edges. An assembly fixture holds the trim elements in position for final assembly in a manner which reduces the size of any gaps which might occur as a result of dimensional tolerances in the panel components.

Abstract: An improved ceiling panel for use in concealed suspension is disclosed which includes framing a panel body member on the sides and rear face thereof in a manner that the lower surface of the panel is determined by the metal framing members. These members are preferrably extruded aluminum and hence the accuracy thereof and hence the accuracy of the lower surface of the panel can be maintained in a closer tolerance range. In addition the framing members include an inwardly directed flange which preferrably is held by an adhesive within an appropriately located kerfed recess in the edge of the body member. This structure serves to stiffen the panel and reduce deflection thereby providing a ceiling system of substantially improved quality. Height variations in ceiling systems are easily recognized and the present disclosure teaches a system of high quality while providing a system which is easy to install and has the advantages of ready access to the area above the ceiling.

Abstract: The invention relates to a flashing frame for roof windows to be installed adjacent to each other with edges facing each other in the installed position with a connecting flange of its upper flashing members extending beneath the roofing and, if need be, with its lower flashing members and required intermediary flashing members, obliquely outwardly bent connecting webs and each with a connecting bar with supporting ribs which rearwardly engage the connecting webs being adjacent to the width of the installation distance and are obliquely bent inwardly on both sides, and at least one inner projection which engages between the facing corner edges of the connecting webs in the installed position, thus maintaining these corner edges at the installation distance.

Abstract: An anchoring cartridge for use in anchoring an anchor element in a hole in a substrate by means of a self-setting composition comprising interactive solid and liquid components. The cartridge comprises a container (1) housing the solid component (4) of the composition, the container being formed of a material such as metal or plastics, which does not absorb the liquid component of the composition. The container has a plurality of holes (2), preferably each between 0.1 mm2 and 500 mm2 in area, whereby when the cartridge is immersed in the liquid component, the liquid passes through the holes (2) into the container (1) and reacts with the solid component (4) to form the self-setting composition. When the cartridge is immersed in the liquid component, loss of self-setting composition through the holes (2) is prevented by, for example, including a thixotropic agent in the composition or by compaction of the solid component (4).

Abstract: A post frame building utilizes wood posts or columns composed of upper and lower sections that are initially detached. The lower sections are set into the ground in the usual manner, and as a consequence, the top of each lower section is at a slightly different elevation. Each lower section bears a reference mark, which for all sections is located the same distance below the upper ends of those sections, and in addition after it is set into the ground, is provided with another reference mark. As to all lower sections these other reference marks are at the same elevation. The upper sections are precisely the same length, and each has a pocket opening out of its upper end. The upper sections are installed on their respective lower sections to complete the columns, but only after leveling blocks are placed in the pockets of the upper sections. The leveling blocks are all initially the same length, that length being less than the depth of the pockets.
