To provide a connection structure between partition walls and a floor slab, and a method for constructing the connection structure, in which a wall material facing a vertical compartment is accurately attached to studs, without any deformation of runners and damage of the connection structure even if pressing forces are applied from the studs to the runners. A connection structure 100 configured to connect a first partition wall 30 and a second partition wall 40 to a floor slab 20 is provided. The first partition wall 30 and the second partition wall 40 are connected to the floor slab 20, and separate a vertical compartment 10 from an upper floor room 13 and a lower floor room 15 that are located adjacent to the vertical compartment 10 and above and below the floor slab 20. A lower runner 31 configured to accommodate a lower end of a first stud 32 is placed on the floor slab 20. An upper runner 33 configured to accommodate an upper end of a second stud 34 that forms the second partition wall 40 is placed below the floor slab 20. A first wall material 50 is fixed to the first stud 32 through a first back batten 80A and fixed to the second stud 32 through a second back batten 80B. The first wall material 50 extends from the first stud 32 to the second stud 24 in the vertical compartment 10.

Spacing bracing members connect to support members through the hole in the support members by using the notches in the spacing bracing member to intersect the hole side edges. The spacing bracing members can pass through the hole having a hook finger end without extending past the support member. Spacing bracing members overlap at the hole in the support member with the notches from the spacing bracing members engaging the hole side edges. The shape and size of the spacing bracing member can vary depending on the shape of the hole and the location and shape of the notches.

A fire-resistant partition wall includes wall studs and first and second walls each including gypsum boards with vertical and lateral joints. The wall studs are on the back side of the vertical joints. A joint base member is provided at the lateral joints. The gypsum boards, the joint base member, and the wall studs are not screwed with a common screw, and (a) the gypsum boards are screwed to only the wall studs and are not screwed to the joint base member, and the joint base member is fixed to the lateral joint position by being inserted between the gypsum boards and the wall studs, or (b) the gypsum boards are screwed to the wall studs and to the joint base member with different screws, and the joint base member is fixed to the lateral joint position by being inserted between the gypsum boards and the wall studs.

A protective enclosure for equipment located outside, such as, for example pipeline and wellhead valves, dewatering pumps, etc. includes a wall frame assembly constructed of a plurality of vertical frame members that are connected together at their tops and bottoms by a plurality of angle-iron members. Wall assemblies comprising insulated wall panels that are connected in a side-by-side relation by tongue-and-grove couplings are attached to the wall frame with the bottoms thereof supported on angle-iron members that connect the bottoms of the vertical frame members. A roof assembly can be attached to the wall frame in a stationary fashion or in a movable fashion to allow the roof to open, permitting access into the enclosure for servicing equipment housed therein. The enclosure has other features as described in the specification in further detail.

A method of forming a lift shaft or similar in a multi-storey building is disclosed. The method includes the casting the shaft in segments (typically in the order of 800 mm deep) and then assembling the segments atop each other to form the shaft. The segments have vertical passages which align to form channels in which rebar can be inserted to tie the structure together.
