摘要： A connector for connecting together first and second elongate members is described. Each of the members to be joined by the connector comprises an open channel extending along the member, the channel having an opening along one side of the member and being partially enclosed by a lip extending along the opening. The connector comprises a first end portion and a second end portion. The first end portion is shaped to fit into the channel of the first member via one end of the first member. The second end portion is shaped to achieve one of two types of engagement with another channel. Firstly, it may be shaped to permit its insertion into the channel of the second member via the opening when the connector is in a first rotational position with respect to the second member. In this case, the second end portion comprises an engagement structure which is shaped to engage with the lip of the second member when the inserted connector is rotated within the channel from the first rotational position into a second rotational position with respect to the second member. Alternatively, it may be shaped to permit its insertion under pressure into the channel of the second member via the opening. In this case, the second end portion comprises a first engagement structure (e.g. a groove) which is shaped to engage with a second engagement structure (e.g. the lip) of the second member when the second end of the connector has been inserted through the opening. In this way, the first and second elongate members (which might be floor/ceiling channels and vertical studs respectively for example) can be of the same profile. As a result, a single metal profile can act as stud, channel, noggin and door head. Furthermore, a single connector type can be used to form all the connections required between these elements.
摘要翻译： 描述了用于将第一和第二细长构件连接在一起的连接器。 要由连接器连接的每个构件包括沿构件延伸的开放通道，通道具有沿着构件的一侧的开口，并且被沿开口延伸的唇部部分封闭。 连接器包括第一端部和第二端部。 第一端部成形为经由第一构件的一端装配到第一构件的通道中。 第二端部成形为实现与另一通道的两种类型的接合中的一种。 首先，当连接器相对于第二构件处于第一旋转位置时，其可以被成形为允许其经由开口插入到第二构件的通道中。 在这种情况下，第二端部包括接合结构，该接合结构被成形为当插入的连接器在通道内从第一旋转位置旋转到相对于第二构件的第二旋转位置时与第二构件的唇缘接合。 或者，其可以被成形为允许其在压力下经由开口插入到第二构件的通道中。 在这种情况下，第二端部包括第一接合结构（例如，凹槽），当第一接合结构（例如，凹槽）被插入穿过开口时，该第一接合结构的形状与第二构件的第二接合结构（例如，唇缘）接合 。 以这种方式，第一和第二细长构件（其可以分别为地板/天花板通道和垂直螺柱）可以具有相同的轮廓。 因此，单个金属型材可以作为螺柱，通道，头盖和门头。 此外，可以使用单个连接器类型来形成这些元件之间所需的所有连接。

摘要： Disclosed is a building board construction with increased surface strength. More specifically, increased nail pull strength is achieved via the application of an external surface coating. The surface coating is ideally applied to a paper faced gypsum building board. In one possible embodiment, the coating is formed from a water soluble polymer.

摘要： A demountable wall partition system includes a first and a second demountable partition panel each including a board and having a front surface and a rear surface, and a flange connection element. At least one panel mount bracket is connected to each board and protrudes from the rear surface and includes a first end flange extending in a first flange plane parallel with the rear surface of the board and a second end flange. The panels are arranged spaced apart with the rear surfaces facing each other such that the at least one panel mount bracket of the respective panel form at least one pair of aligned panel mount brackets, wherein said brackets are connected to each other by means of the flange connection element which is connected to the end flanges of the brackets such that the flange connection element is supported by the brackets.

摘要： The application describes a slurry spread quantification system (200) comprising a forming table including a forming area and at least one slurry outlet (120) configured to, in use, dispense a slurry (130) into the forming area, a sensor (210) trained on the forming area and configured to capture an image of the forming area; and a processor (220) operable to: analyse the image to identify the slurry (130); determine at least one characteristic of the slurry (130); and output at least one indication of the at least one characteristic of the slurry (130). A method, a computer implemented method and a non-transitory computer readable storage medium comprising instructions, that when executed on a computing device cause the computing device to control a system (200) as described are also discussed.

摘要： A novel design of rails for a suspended ceiling, the rails including expansion absorbers. The absorbers are produced so that the rails can absorb an expansion while maintaining the integrity of the ceiling, so that the ceiling panels do not fall in the event of a fire. The rails maintain a significant load-bearing capacity despite the presence of one or more expansion absorbers over the length thereof.

摘要： A gypsum product has a first polymeric additive and a second polymeric additive distributed therein, wherein the first polymeric additive is a synthetic polymer and the second polymeric additive is starch.
It has been found that the combination of starch and a synthetic polymer may result in one or more of the following advantages in the manufacture and performance of gypsum products: increased strength; greater ease of manufacturing due to the increased fluidity of stucco slurries containing both additives; and increased resistance to hygroscopic expansion.
