They're restoring them but they've run into problems with joists over partition walls.

他们都在装修房子，做隔墙的时候遇到了承重的问题。

Two planks placed cross-wise at intervals, with a joist to serve as a roof; and that is all.

两块木板间隔交叉放置， 用托梁作为屋顶； 仅此。

They also gave money to the carpenters and builders to purchase dressed stone, and timber for joists and beams for the buildings that the kings of Judah had allowed to fall into ruin.

就是交给木匠、石匠，买凿成的石头和架木，与栋梁，修犹大王所毁坏的殿。

The case of the homestead was serious. Hannah's account had not been exaggerated in substance: the gable end of the house was open to the garden; the joists, left without support, had dropped, and with them the upper floor.

宅基地的情况很严重。汉娜的描述在实质上并没有被夸大：房子的山墙端通向花园；没有支撑的托梁掉了下来，楼上也跟着掉了下来。
