A glulam construction method suitable for relatively small-sized wooden buildings is disclosed. Each joint metal has its plate portion and pipe portion joined in a racket-like shape. At an end of a column, a slit is formed to open at a column end surface and to extend in a column width direction. At an abutment part in a beam abutting on the column end surface, mortises penetrating in a beam depth direction are formed at two positions appropriately spaced from each other in a span direction. Each joint metal has its pipe portion fitted in the corresponding mortise and has its plate portion fitted in the slit of the column. The joint metals are fixed in the column and the beam by drift pins or bolts and thereby establish rigid connection therebetween.

Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.

An assembly channel embedded in a concrete structure includes: bolts coupled to a bracket adapted to support an object to be supported; a support member open on top thereof and having both side ends bent inwardly therefrom in such a manner as to prevent heads of the bolts inserted thereinto from being escaped therefrom; a fixed member fixedly coupled to the underside of the support member in such a manner as to be embedded in the concrete structure; at least one or more length reinforcing materials mounted on the inner surface of the fixed member in a longitudinal direction of the fixed member so as to reinforce the strength of the fixed member; and a horizontal plate disposed between the support member and the fixed member in such a manner as to be coupled to the support member.

The present application relates to a prefabricated concrete beam-column node and a construction method thereof. The construction method of the prefabricated concrete beam-column node includes: assembling node connectors, and mounting studs on each node connector; welding a circumferential reinforcing plate with a groove hole in the center to a middle-rear section of each node connector; mounting a longitudinal rebar on each circumferential reinforcing plate; pouring a concrete beam between two circumferential reinforcing plates; welding a hidden corbel to a side flange of each of structural columns; hoisting the concrete beam, and overlapping each node connector with the corresponding hidden corbel; welding each node connector to the corresponding structural column; and pouring the concrete beam between the circumferential reinforcing plates and the structural columns.

The present invention relates to a precast concrete member using a PC member, which comprises a prefabricated plate and fixing channels, and is used as a linear member for a column which is an axial force member, as a planar member for a wall which is an axial force member, or as a linear member for a beam or a girder which is a flexural member. A preferred embodiment of the present invention provides a premade precast concrete member having a PC body formed at a predetermined length and multiple steel reinforcements embedded within the PC body along the longitudinal direction, the precast concrete member comprising: a plate assembly in which a pair of board-like plates having a pair of coupling holes formed to be penetrated at a regular interval are formed so as to be spaced apart from each other and to face each other, or two pairs of board-like plates are spaced apart from each other so as to face each other, with one end of each thereof being embedded into one or both longitudinal ends of the PC body, and the other ends thereof protruding, wherein the plate assembly comprises a connecting member of which a part embedded into the PC body of the plate is welded to one side of the steel reinforcement, and both ends are respectively bolt-coupled to the coupling holes of a pair of plates so as to connect a part embedded into the PC body of a pair of facing plates; and fixing channels which comprise a U-shaped channel having an opening formed on the top thereof and multiple anchor bodies coupled to the rear surface of the U-shaped channel, the opening of the U-shaped channel comprising a rib which is formed to be bent inwardly, wherein at least two rows of fixing channels are embedded at regular intervals into one side surface of the width direction of the PC body or into at least one pair of corresponding surfaces of the width direction of the PC body.

A pre-fabricated dome and a spherical structure include strut assembly sets, into which glass panels or synthetic resin transparent plates are to be inserted, are assembled into 5 sets of hexagonal modular assemblies around a pentagonal assembly to build a primary pentagonal modular assembly, and further 5 sets of primary pentagonal modular assemblies, into which upper and lower, (outer and inner) struts are assembled in 2 layers (of outer and inner walls), are interconnected to build a semi-spherical dome, and if 12 sets of primary pentagonal modular assemblies are assembled, a solid cylindrical structure can be built to provide a perfect block between the outdoor and the indoor so that the room temperature will not be affected at all by the outdoor temperature.
