An article of manufacture for an earthquake safety protection device (ESPD) according to the present invention is disclosed. The ESPD consists of an earthquake support pole and mating support members to create survivable space around the support pole should a room be damaged in an earthquake. The ESPD may also comprise a reinforced frame within an interior door of a building. The reinforced frame resists damage from an earthquake that may prevent the interior door from opening. Opening or removal of the inner door protected by the reinforced frame creates a means of safely exiting a room in spite of damage to the interior door and its corresponding door frame. The ESPD may also include a mechanism to prevent a mobile hospital bed from moving about a room during an earthquake.

An anti-seismic performance reinforcement structure of a masonry structure and a construction method of the same are proposed, where a deformed bar is constructed to be tied to the entire circumference of the masonry structure at every predetermined height thereof such that the masonry structure is connected to a wall, thereby simplifying a construction process, and inducing the masonry structure and the wall to be moved integrally to each other during an earthquake so as to prevent the masonry wall from collapsing. The method of performing anti-seismic performance reinforcement and crack repair of the masonry structure includes: removing a predetermined depth of a horizontal joint; mounting the cross joint by forcibly press-fitting the cross joint having the press-in holder and the horizontal holder to a perforated position; fixing a deformed bar fixture to the wall; and tying the entire circumference of the masonry structure with the deformed bar.

A novel function-recoverable prefabricated seismic shear wall structure with replaceable components, which includes main structural components, connecting components and replaceable components. All components are connected by bolts or pins. The connections can provide sufficient strength to effectively connect adjacent upper and lower wall panels, or wall panel and coupling beam, together. The replaceable components are installed in the bottom region of the wall and coupling beams, which provide sufficient bearing capacity and stiffness for the building structure under service loads and dissipate seismic energy under the earthquake. The damage concentrates on the replaceable components which could be easily replaced after a strong earthquake so that the function of the building structure could be quickly restored. In addition, the replaceable components with different energy-dissipation mechanisms facilitate the shear wall structure to have multiple seismic fortification lines, and improve the seismic performance of the building structure.

The present disclosure discloses a wave-shaped steel plate energy dissipation damper, and a processing method and a mounting method thereof, and belongs to the technical field of energy dissipation and shock absorption of engineering structures. The damper includes a shell, a shock absorption mechanism, and supporting seats. There are two supporting seats which are respectively mounted at a head end and a tail end of the shell. The shock absorption mechanism includes a moving mechanism and at least one wave-shaped steel plate. The wave-shaped steel plate is located in the shell. One end of the wave-shaped steel plate is fixedly connected to the shell. One end of the moving mechanism extends into the shell to fixedly connect the other end of the wave-shaped steel plate. The other end of the moving mechanism is fixedly connected to the bottom of the supporting seat located at the tail end of the shell.

Embodiments of the disclosure are directed towards a method to reduce the weight of any given concrete product or project by insertion during the pour, while increasing the strength of the product or project.

Consisting of a composite hybrid block of vertical grain torsion box grid filled with rigid foam, which is glued into place, the Reinforced Honeycomb Concrete Substrate is inserted in sections, and allowed to remain during cure time and thereafter.

Besides displacement of heavy cement or concrete, Reinforced Honeycomb Concrete Substrate is also insulated for sound deadening and climate control, and acts as a vibration and shock absorber, greatly enhancing sustainability, while reducing the tendency to crack or otherwise fail.

The Reinforced Honeycomb Concrete Substrate may be precast or cast on site and may be used for a wide variety of sizes of product and projects, in anything from art to heavy construction.
