Abstract: The present invention broadly comprises a tower and a method and apparatus for constructing a tower, where one embodiment of apparatus includes a foundation, a plurality of lower staves located on the foundation, and a plurality of upper staves located above the lower staves, the upper staves having a poured in place concrete or grout joint between each adjacent upper stave.

Abstract: 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.

Abstract: The present invention broadly comprises a method and apparatus for constructing a concrete structure. In one embodiment, a structure includes a column section and a beam section. One of the column section and the beam section includes an assembly with a threaded rod, and the other of the column section and the beam section includes an assembly having an aperture configured to receive the threaded rod.

Abstract: An assembly includes a first block including a first end; and a second block assembled with the first block at a same height as the first block, the second block including a second end facing the first end of the first block. The first block and the second block are connected to the assembly such that there is no structural connection between the second end of the second block facing the first end of the first block.

Abstract: The present invention broadly comprises a method and apparatus for constructing a concrete tower. In one embodiment, a tower construction apparatus includes an alignment jig and a pre-cast concrete element located on the alignment jig.

Abstract: Various implementations comprise a method and apparatus for constructing a concrete structure in stages. In various implementations, an apparatus includes a base, a support column located on the base, and a movable scaffolding rotatably coupled to a top of the support column. According to various other implementations, a method for assembling a tower stage includes: (1) providing a base platform; (2) coupling a pole to the base platform; (3) disposing two or more staves around the pole; (4) coupling the staves together to form the tower stage; and (5) removing the tower stage from the platform.

Abstract: A structure includes two legs, a horizontal support, and an adhesive. Each of the two legs includes at least one aperture. The horizontal support has two ends. A first end is located in an aperture in a first leg of the two legs and a second end of the horizontal support is located in an aperture in a second leg of the two legs. The first end of the horizontal support has a cross-sectional area that is less than a cross-sectional area of the aperture in the first leg and the second end of the horizontal support has a cross-sectional area that is less than a cross-sectional area of the aperture in the second leg. The adhesive is within each aperture and in contact with the horizontal support.

Abstract: A pipe rack and a method for making a pipe rack where the pipe rack may include at least one foundation, two legs, and a horizontal support. The two legs are supported by the at least one foundation. Each of the two legs includes at least one aperture. The horizontal support has two ends. The first end is located in an aperture in a first leg of the two legs and a second end of the horizontal support is located in an aperture in a second leg of the two legs. A rod forms a joint between the foundation and one of the two legs. The rod is located in the aperture in the upper surface of the foundation and in an aperture in a lower surface in the one of the two legs.
