A vehicle-mounted concrete pump includes: a concrete pump system designed to convey concrete; a hydraulic drive pump system which is designed to drive the concrete pump system and comprises a hydraulic pump drive shaft; a combustion drive motor system designed to drive the hydraulic pump drive shaft of the hydraulic drive pump system; and a liquid-cooled synchronous drive motor which is designed to drive the hydraulic pump drive shaft of the hydraulic drive pump system.

A securing system for a portable basketball pole assembly is disclosed. The securing system includes ground screws which secure in the ground on either side of a base of the portable basketball pole assembly. A strap is extended from one ground member to the other over the base to hold the base securely to the ground and prevent tipping. Additional straps may be used to extend from the ground members to the pole to further secure the pole. In certain preferred embodiments, separate straps extend from the ground members to the pole. In other embodiments, a single strap is used. The straps are attached to the pole via a pole attachment member. The pole attachment member may conveniently be an after-market part which fits around an existing pole and provides a receiving element to receive the strap or straps. Buckles may be included to allow the straps to be tightened or loosened.

The present invention is a three-dimensional printing system which is capable of printing with multiple different printing materials, including homogenous materials, such as cement paste, or heterogeneous materials, such as concrete. Functionality is accomplished by novel, critical structures including but not limited to a movable gate capable of controlling the flow of printing materials without clogging or becoming otherwise damaged. The system has a print head that discharges printing material through a discharge aperture. The movable gate is rotatably connected to the print head, allowing it to cover the discharge aperture and cut off the flow of printing material when actuated and rotated into position. Certain embodiments also include hose positioning systems to prevent hoses delivering printing material from disconnecting or damaging the printed structure.

A tree house propped upon a simulated tree trunk has a platform, a cabin thereon, a main support column supported in a ground anchor, a plurality of diagonal struts, and a variety of simulate tree dressings for the column and struts. The cabin is built upon the platform and forms an inner living space that is served with potable water utilities, waste water utilities, and public-utility electric service. The main support column extends downward from the platform about a relative center of mass of the platform and cabin together, to ultimately sink into the ground anchor. The plurality of diagonal struts extended diagonally downward from the cabin radially spaced away from where the column extends downward from the platform, and join the column intermediate the platform and ground anchor. There furthermore are simulated tree trunk dressing covering the column, and, simulated tree branch dressing covering the struts.

Apparatuses, components, methods, and techniques for selectively texturing concrete surfaces are provided. An example method of providing a surface portion of an architectural precast concrete wall panel with an abraded texture is provided. The method includes a step of spraying a surface portion of an architectural precast concrete wall panel with an aqueous-based particulate abrasive mixture under conditions adequate to at least partially abrade the surface portion. An example sprayer system for abrading a concrete surface is also provided. The system includes an aqueous-based particulate abrasive mixture dispenser including a spray nozzle arrangement. The system also includes a material communication assembly in abrasive flow communication with the aqueous-based particulate abrasive mixture dispenser. The system also includes a dispenser positioning arrangement.

Disclosed herein is a cage apparatus for construction, which includes: a cage base having a base frame supporting a base foothold to carry out frame work of a building; and a cage gondola unit arranged to be operated relative to the cage base to carry out exterior finish work of the building.

An underlayment for a floor includes a dimpled substrate having a generally planar top side, an opposed bottom side, and a plurality of dimples formed therein. Each dimple is bounded by a dimple wall, and includes a dimple opening along the top side. A smoothing layer is bonded beneficial to the top side of the dimpled substrate and overlays and occludes the dimple openings.

The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.
