The invention discloses a bottom template for a building floorslab and a construction method thereof. The bottom template for the building floorslab comprises supporting ends (1), connecting plates (2), connecting cover plate (3), angular placing parts (8) and a cover plate (9). The plurality of supporting ends (1) or / and the connecting plates (2) or / and the connecting cover plates (3) are spliced in sequence to form a #-shaped template; the angular placing parts (8) are fixed on the #-shaped template and the cover plate (9) is placed on the angular placing parts (8) to form the bottom template for the building floorslab. When the bottom template is detached, floorslab concrete is poured on the top of the bottom template before the angular placing parts (8) are detached, then the cover plate (9) is detached, and the supporting ends (1), the connecting plates (2) and the connecting cover plates (3) are detached after the floorslab concrete reaches the strength. The bottom template is suitable for the construction of a reinforced concrete hollow rib floorslab and the construction of the solid floorslab. During the construction of the hollow rib floorslab, the bottom template can be used so that the side template of the hollow rib floorslab can be detached conveniently and the standardized construction of the hollow rib floorslab can be realized.

The invention relates to an assembling type building wall which is composed of unit walls mounted between upper and lower floor slabs, wherein vertical corresponding metal square pipes are fixedly mounted on the upper and lower floor slabs; square grooves matched with the metal square pipes are respectively arranged on the upper and lower parts of the unit walls; metal threaded pipes are respectively embedded on the two sides of the groove on the upper part; fastening bolts are arranged in the metal threaded pipes; when the fastening bolts are moved forward, the front ends of the fastening bolts can be inserted into the through holes of the metal square pipes; the metal sleeves are respectively embedded on the two sides of the groove on the lower part; metal rods are arranged in the metal sleeves; cams are fixedly mounted at the center of the metal rods; and when the cams are rotated till the long edge is downward, the cams are in tight contact with the upper wall of the metal square pipe on the lower part so as to form self-locking. The building wall has the advantages that the unit walls can be conveniently and quickly assembled, so that the labor intensity is low, and the construction period is short; the mounting precision of the unit walls is high, so that the standard construction of the wall can be realized, and the construction quality is high; the unit walls are firmly mounted, so that the anti-seismic property is excellent; and the unit walls can be freely detached and exchanged, so that the maintenance is convenient.

The invention relates to the field of construction engineering, in particular to a reusable fabricated end seal structure for an immersed tube tunnel. The end seal structure is mainly composed by combining at least one package door panel, support girders of the package door panel and an outer edge seal support component, wherein a plurality of support girders are sequentially arranged along the transverse section of a pipe and respectively provided with a vertical mounting surface; the outer edge seal support component is provided with an edge seal surface continuously arranged along the inner wall of the pipe; the edge seal surface and the vertical mounting surface of each sequentially-arranged support girder are located in the same plane and combined to form a mounting surface of the package door panel; a plurality of openings are formed between the vertical mounting surface and the edge seal surface; and at least one annular seal rubber strip is arranged on the package door panel, and the package door panel is bolted and fixed on the mounting surface, wherein the seal rubber strip is located and compressed between the package door panel and the mounting surface. The reusable fabricated end seal structure for the immersed tube tunnel has the advantages of greatly improving the construction efficiency and fulfilling the standardized construction.

The invention relates to an anti-seismic system of an antique building structure. The anti-seismic system sequentially comprises a column-stone interconnecting anti-seismic structure, a bearing anti-seismic structure, a wall-window anti-seismic structure, a framework anti-seismic structure and a roof from bottom to top, wherein the column-stone interconnecting anti-seismic structure comprises column-stone structural units; every two adjacent column-stone structural units are mutually connected by first connectors; each column-stone structural unit comprises a middle column-stone anti-seismic structure and a bottom column-stone anti-seismic structure; the bearing anti-seismic structure comprises a gold table, bucket arch structures, first wall body structures and porch column structures; the wall-window anti-seismic structure comprises a second wall body structure and a window frame structure; the window frame structure comprises a window frame and a windowsill; the framework anti-seismic structure comprises beams, columns, bucket arches and third connectors; the roof is formed by splicing roof panels, roof girders and purlins. The anti-seismic system of the antique building structure, provided by the invention, has the characteristics of foundation integral connection and horizontal and vertical flexibility as well as has significant anti-seismic effects.
