Abstract:
The present invention relates to a design of a block construction type retaining wall and prevents overturning stability from being excessively evaluated by calculating moment and overturning resistance with a weight up to the height of a hinge rather than the entire weight of the retaining wall in order to increase the reliability of stability of the retaining wall when overturning safety is calculated. The apparatus for measuring the shear capacity of a block reduces errors by making the situation that actual transverse soil pressure is applied.

Abstract:
The present invention is to provide a spring hanger bracket which comprises a body unit (110), a frame connecting member (120), and spring connecting members (130, 140). The body unit includes a bent part that both ends are bent in the same direction. The frame connecting member is connected to the body unit and inserted to a vehicle frame. The spring connecting members are connected to the bent part of the body unit and support one end of a leaf spring as one end of the spring connecting member is connected to the leaf spring. A first connection groove (115) formed into a semicircle shape is at the bent part (113) of the body unit and a second concave connection groove (125) formed into the semicircle shape is placed at one end of the frame connecting unit (120). A third connection groove (133) wherein the second connection groove is coupled to the first connection groove is placed on the upper outer periphery of the spring connecting member. The third connection groove has the certain depth and width and is formed into the semicircle shape.

PURPOSE: A floating dock for repairing a ship is provided to easily approach a ship to be repaired because the floating dock has a propulsion unit and improve the durability, shock resistance, and abrasion resistance thereof. CONSTITUTION: A floating dock (100) for repairing a ship comprises a dock body (110), a pump (120), a propulsion unit (130), and solid ballast (140). The dock body has a seawater storage space and a ship receiving space. The pump pumps water stored in the seawater storage space. The propulsion unit moves the dock body. The solid ballast is installed on the bottom surface of the dock body to stabilize the dock body.
Abstract:
PURPOSE: A parallel shear wall for buildings is provided to simplify the arrangement of bars in a connection beam and to prevent connection beams and shear walls from being damaged by improving the effects of shear walls in absorbing and emitting lateral load energy. CONSTITUTION: A parallel shear wall (100) for buildings comprises shear walls (110, 120), a connection beam (130), and a damper (140). The shear walls are separately set up at both sides at regular intervals to be parallel to each other. The connection beams are installed at regular intervals in the longitudinal direction of the shear wall. The connection beam laterally connects the shear walls to each other to absorb and emit energy due to lateral loads applied to the shear walls. The damper is spaced apart from the shear walls and is installed in a silt space (S) to absorb and emit energy delivered to a plurality of beams (131, 132).
Abstract:
PURPOSE: A batch composition of borosilicate based roving fiber glass is provided to lower melting temperature of robbing fiber glass batch and to reduce manufacturing cost of the roving fiber glass by including cullet of non-alkali alumina borosilicate based display glass. CONSTITUTION: A batch composition of borosilicate based roving fiber glass contains 66-470 parts by weight of cullet based on 100 parts by weight of talc among the batch composition. The cullet is one selected from non-alkali alumina borosilicate based cullet for organic light-emitting diode and nonalkali alumina borosilicate cullet for thin-film transistor liquid crystal display. The batch composition includes 0-11 parts by weight of colemanite, 74-216 parts by weight of limestone, 0-8 parts by weight of borax, and 0-4 parts by weight of soda ash based on 100 parts by weight of the talc on top of the non-alkali alumina borosilicate based cullet. The section diameter of the roving fiber is 15-30 μm.
Abstract:
PURPOSE: A concrete floating structure and a construction method thereof are provided to simplify the connection work of precast concrete modules and to prevent the performance degradation of a structure by improving resistance to shear force applied to the connection portions of the modules. CONSTITUTION: A concrete floating structure (100) comprises multiple precast concrete modules, tendons, and tendon anchorages. The precast concrete modules have wall portions for connecting upper and lower slab portions (121,121',122,122') to be coupled to each other. The tendons apply prestressed force to the precast concrete modules. The tendon anchorages are coupled to both ends of the tendons and anchor the tendons to the precast concrete modules. Multiple shear keys, which resist shear force, are formed on the touching surfaces of the precast concrete modules.
