摘要:
A foundation structure is made up of a screw that is vertically adjustable into a pile to a desired height, a ball joint connected to the screw, and load bearing components that can be adjusted on the ball joint in 3-dimensional space with respect to the position of the pile. The load bearing components include one or more plates that define one or more hollow slots into which one or more bolts can be held in place vertically while still having allowance for lateral motion. A load bearing plate at the top of the structure can be laterally translated based on movement of the bolt. The load bearing plate is removably coupled to the floor of a building. The structure allows for vertical, lateral, and angular adjustment, providing tolerance for foundation misalignments due to inconsistencies inherent to topography and/or offset between an intended and an actual point of installation.

A building panel comprises 2 parallel slabs separated by a layer of insulation. Each of a pair of planar plate-like lift wings has a 1st and a 2nd lift wing portion. Each of the 1st lift wing portions is penetrated by at least one through opening. A planar plate-like lift head defines a plane of symmetry orthogonal thereto. 1st and 2nd lift head portions are symmetrically disposed on either side of the plane of symmetry. Each lift head portion is penetrated by at least one through opening symmetrically disposed relative to the plane of symmetry. Each lift head portion is penetrated by at least one through opening symmetrically disposed relative to the plane of symmetry. The lift head is attachable to both lift wings when the 1st lift wing portions are orthogonal to the plane of symmetry. The lift head is detachable from both lift wings to eliminate thermal conductivity between the lift wings.

A piling driver (1) to drive a high capacity and maximum continuous length of underpinning pile (61, 62) of at least equal to the clear floor height of a building. The modular piling driver (1) can be assembled on site to drive a pile into the ground within a small confined space under a limited head room comprising of; an underpinning pile (61, 62), a clamping block (2) with horizontal hydraulic clamps (25, 29), a thrust block frame structure (3) with a C-shaped horizontal beam (34) supporting a pair of vertical hydraulic jacks' (4) with corresponding rams (43) that drives the clamping block (2) along the two vertical holding frame members (5) which is supported by a pair of upper and lower locking pins (54) on to the parallel beams (7) that will bear against the soffit of the foundations (8). A method of push pull piling characterized in that apart from only using the counterweight is to utilize the pull resisting force of the adjacent underpinning piles (61a, 61b, 61c) through a system of inter-connecting at least two units of the piling driver (1) into an assembly (9).

Disclosed is a construction method of a cellar for a building completed. The construction method includes fixing supporting structures to bottom concrete of the building; installing a press-in machine on the supporting structures; inserting posts for supporting the building into the foundation under the building by inserting hollow piles into the holes to then insert the piles into the underground using the press-in machine, stacking new piles on the inserted piles, and sequentially inserting the piles using the press-in machine; excavating a foundation under the bottom concrete of the building to prepare an underground space when the building is supported by the posts; and placing the concrete on the horizontal and vertical faces of the underground space prepared by the excavating the bottom concrete of the building.

A framework for moving a displayer over a foundation of a building to display the architectural features of the building onto the foundation. The framework contains a displayer that projects the images by either pigment or laser to increase the efficiency of constructing a building. The framework provides movement of the displayer in order to display the features on all portions of the foundation. The displayer may project the image on varying levels of the building by increasing the height of the framework. Movement of the displayer may be performed by various means and the displayer may move along the framework and the carrier for the displayer.

A floor slab support system for jacking and stabilizing a sagging or cracked floor or other such slab. Holes of 3½″ diameter, for example, are drilled through the slab and a pipe pier driven downwardly until reaching bottom. A connector sleeve matching the slab hole size is temporarily suspended in the slab hole and L shaped brackets are inserted into the sleeve and maneuvered to extend outwardly through slots in the sleeve to engage the underside of the slab. A threaded rod with a threaded positioning member and a bottom stop is inserted through the sleeve and into the pipe pier, and the L brackets extended through the sleeve and maintained outwardly by the threaded positioning member. Once in position, the threaded rod is rotated to screw the sleeve and brackets upwardly to support the slab. Finally, the top of the rod is cut off and the hole filled with concrete.

A lifting assembly for raising and supporting a load includes a removable and reusable lifting bracket. The lifting bracket is designed to fit around and support a support bracket that supports a load. The support bracket is installed on the pole of the pier and engages the edge of the load. The lifting bracket is removably attached to a jacking apparatus for pushing or pulling the piering pole through the support bracket and raising the load on the support bracket. After the lifting operation, the lifting bracket is removed from the jacking apparatus and the support bracket attached to the piering pole for use on adjacent piers and on other lifting assemblies.

There is disclosed an underpinning pile to provide an efficient, simple and sure method in driving and lifting the foundation and at the same time securing the direct transference of preload without further loss of preload from the building into the newly completed driven pile. A pile anchor head (11) is provided that receives a pile (12) and is provided with a lifting means (13). The pile anchor head (11) and lifting means (13) receive the building load and transfers it to the pile (12), which allows practically any kind of material and shape of pile (12) to be used.

The present invention provides processes for infrastructure repairs and geo-stabilization with a low-exotherm polyurethane foam, grout or elastomer. The inventive process involves at least partially filling a cavity in the infrastructure or earth with a low-exotherm polyurethane foam, grout or elastomer made from at least one polyisocyanate, at least one isocyanate-reactive compound and an organic particulate material capable of absorbing heat, optionally in the presence of one or more chosen from water, surfactants, pigments, catalysts, alkali silicates and fillers and curing the polyurethane foam, grout or elastomer. The inventive processes may improve the repair of buildings, foundations, roads, bridges, highways, sidewalks, tunnels, manholes, sewers, sewage treatment systems, water treatment systems, reservoirs, canals, irrigation ditches, etc.; and in the geo-stabilization of mines, caves, wells, bore-holes, ditches, trenches, pits, cracks, fissures, craters, postholes, potholes, sinkholes, wallows, waterholes and the like.
