The reference node
(57) Abstract:The invention relates to the construction and can be used in the construction of surface and underground structures, as well as for strengthening of structures basements of existing buildings in areas where there is a risk of exposure to explosions. The reference node contains an outer sleeve, the lower end welded to the base plate. The upper end of this sleeve is overlapped by the flange cover with vertically fixed inside the guide tube. In the cavity of the outer sleeve with the annular gap installed anchor sleeve. The annular gap between the liner filled with a pliable material. In the lower part of the support sleeve on the support plate stacked layer of pliable material, and the upper end of the supporting sleeve rests the tip inserted into the tubular rack, which has been passed through the channel guide tube vertically fixed in the flange of the cover. 1 Il. The invention relates to the construction of surface and subsurface structures and can be used in the construction of surface and underground structures, as well as to strengthen the construction of the basements of existing buildings in areas where there is a risk of exposure to explosions.Known welded to the metal rack and the base plate. The base plate is rigidly fastened to the base by means of bolts passed through holes in the lining attached on the top of the ends of the gusset plates (Fig.11,21, page 55, Vakhnenko P. F. and others "Construction and design of buildings and structures". -M. stroiizdat, 1980, 423 S.).The disadvantages of these reference nodes are their permission under dynamic impact, unfitness for further exploitation and displacement of the anchors.Increasing the carrying capacity and the indestructible such reference nodes is achieved by applying a plastically deformable elements.In this case, the reference nodes contain deformable under overload anchor sleeve, a vertically mounted on a support plate (German patent N 1634364, CL E 02 D 7/34, 1972).The drawback of such reference nodes are enlarged dimensions, increasing the intensity and weight.Closest to the invention is the reference node representing the deformable under overload anchor sleeve, a vertically mounted on a support plate (German patent N 1634364, CL E 02 D2 7/34, 1972).This reference node is taken as a prototype, the prototype is the base object.The disadvantages of this ptx2">The purpose of the invention, reduce size, reduce material consumption and its own weight.This goal is achieved by the fact that the reference node is equipped with an external sleeve, which covers the annular gap anchor sleeve is welded to the lower end to the base plate and covered by the flange of the cover with the guide tube, and a tubular stand through the guide tube and its tip is supported on the supporting sleeve, and the annular gap between the liner and the lower part of the sleeve filled with a pliable material.The drawing shows the proposed reference site.It consists of a base plate 1, the flange of the cover with the guide tube 2, the outer sleeve 3, the supporting sleeve 4, bit 5, a tubular rack 6, pliable material 7 and 8.The base plate 1 the reference node is attached by anchors to the base 9 or is mounted on the base 9 without fastening.Support node operates as follows.A dynamic load acting on the tubular rack 6, causing its vertical movement together with tip 5.The tip 5 is included in the channel of the supporting sleeve 4, causing it to radial deformation. Further, the impact of pornoteenage dynamic effects pliable material 7 receives a limiting strain compression and transmits further impact on the external wall of the bushing 3. When limiting the length of stroke of the rack 6, the tip 5 is based on the layer of pliable material 8. Hour 6 is fixed in a vertical position through a guide tube fixed in the flange of the cover 2.In the organized give the reference node, the load on the rack 6 is reduced several times.Thus, the application of the proposed solution allows to reduce the size, reduce the consumption of materials and its own weight. The reference node, comprising a vertically installed on the base plate deformable anchor sleeve, characterized in that it is equipped with an external sleeve, which covers the annular gap anchor sleeve is welded to the lower end to the base plate and covered by the flange of the cover with the guide pipe and tubular stand with the tip at the lower end, which has been passed through the guide tube and its tip is supported on the supporting sleeve, and the annular gap between the liner and the lower part of the sleeve filled with a pliable material.
FIELD: building, particularly for erecting pile-plate foundations for industrial buildings and structures, for instance for main buildings of heat power plants.
SUBSTANCE: method involves arranging drilled cast-in-place pile, grouting plate grillage and installing antivibration mounts. Anchorage reinforcement is placed in pile heads and arranged along marked building axes. Anchorage reinforcement is then grouted and resilient antivibration mounts are installed at pile heads. Resilient antivibration mounts are fixed in plane on anchorage reinforcement with the use of fasteners so that antivibration mounts may perform restricted movement. Installed on antivibration mounts is rigid metal foundation frame of upper building in which anchoring reinforcement for securing skeleton of building to be erected is installed. Reinforcement rods and supply lines are inserted in process orifices formed in foundation frame beams and frame is grouted to form panel grillage.
EFFECT: reduced work content, increased simplicity and speed of bearing grillage frame erection; improved building stability.
