The subject application relates to the technical field of pavement construction, and in particular to the expansion joint construction for a large-area concrete floor, including the expansion joint (1) formed on the body of the floor (2), and two corner steel bars (3) provided at the tops of the two vertical sides of the expansion joint (1), respectively, and the tops of the two corner steel bars (3) are flush with the top of the floor body (2). Reinforcement bars (4) are pre-installed in the floor body (2), and a number of anchor bolts (5) are provided on each of the two corner steel bars (3). A partition (6) configured to separate the concrete is provided under one of the two angle steel bars (3). A foam plate (8) is attached between two angle steel bars (3), extends downward to approach the bottom of the expansion joint (1) and rests against the bulkhead (6). The anchor plate (9) for pressure reduction passes through the partition (6) in parallel, the first end of the anchor plate (9) for pressure reduction is inclined downward along the direction starting from the expansion joint (1), and the other end of the anchor plate (9) for pressure reduction is passed through the expansion joint (1) and coated with the sleeve (10) for the anchor plate (9) formed in the body of the floor (2). Predmetna prijava se odnosi na tehničku oblast konstrukcije kolovoza, a posebno na dilatacionu spojnu konstrukciju za betonski pod velike površine, uključujući dilatacioni spoj (1) formiran na telu poda (2), i dve ugaone čelične šipke (3) obezbeđene na vrhovima dve vertikalne strane dilatacionog spoja (1), respektivno, i vrhovi dve ugaone čelične šipke (3) su u ravni sa vrhom tela poda (2). Šipke (4) za ojačanje su unapred ugrađene u telo poda (2), a na svakoj od dve ugaone čelične šipke (3) je obezbeđeno više ankernih zavrtnja (5). Pregrada (6) konfigurisana za odvajanje betona je obezbeđena ispod jedne od dve ugaone čelične šipke (3). Ploča (8) od pene je pričvršćena između dve ugaone čelične šipke (3), proteže se nadole da bi se približila dnu dilatacionog spoja (1) i naslonila se na pregradu (6). Anker ploča (9) za smanjenje pritiska prolazi kroz pregradu (6) paralelno, prvi kraj anker ploče (9) za smanjenje pritiska je nagnut nadole duž pravca koji polazi od dilatacionog spoja (1), a drugi kraj anker ploče (9) za smanjenje pritiska je provučen kroz dilatacioni spoj (1) i obložen rukavom (10) za anker ploču (9) formiranu u telu poda (2).
