Embodiment 1
[0026] The construction method of the electric shaft bridge of the present invention through the floor slab retaining platform comprises the following steps:
[0027] a. The prefabricated concrete member with a Π-shaped cross-section includes the following steps:
[0028] (1) Determine the prefabricated Π-shaped concrete member according to the size of the opening of the electrical shaft.
[0029] see now figure 1 , figure 1 It is a structural schematic diagram of a Π-shaped concrete member according to an embodiment of the present invention. As shown in the figure, the Π-shaped concrete member is provided with a panel 1 and side panels 2 on both sides.
[0030] (2) Support the formwork and pour concrete according to the Π-shaped concrete member, and when the poured Π-shaped concrete member reaches half the height, insert the pre-embedded right-angled steel bars 3 respectively in the two right-angled corners of the concrete member to increase the Π Shaped concrete member s...

The invention relates to a construction method of a water retaining platform for an electric shaft bridge penetrating a floor slab. The construction method is characterized by comprising the following steps of (a) prefabricating a concrete member with an n-shaped section; (b) paving a mortar cushion layer at the opening of an electric shaft; (c) installing the n-shaped concrete member; and (d) pouring ground concrete, using the n-shaped concrete member as a side formwork of the opening of the electric shaft, and completing ground concrete pouring. Compared with a traditional construction method of the water retaining platform, the construction method of the water retaining platform for the electric shaft bridge penetrating the floor slab has the advantages that during ground construction, the prefabricated water retaining platform member is used as the side formwork at the opening of the electric shaft in the floor slab penetrating position, ground decoration and the water retaining platform of the opening of the electric shaft are constructed at the same time, so that the situation that the water retaining platform is constructed after ground construction is completed is avoided, the construction time is saved, and the lower end of the prefabricated water retaining platform member is poured in the ground, so that the overall stability is good, and the prefabricated member is attractive in forming.
Description
technical field [0001] The invention relates to a water-retaining platform for retaining water, in particular to a construction method for an electric shaft bridge passing through a floor-slab water-retaining platform. Background technique [0002] Electrical shafts, also known as cable shafts, are channels for laying vertical trunk cables in high-rise or multi-storey buildings. Trays are brackets used to support and place cables. The electrical shaft bridge is a bridge laid in the electrical shaft. After the installation of the bridge frame and the laying of cables are completed, a sill with a height of about 5cm protruding from the ground, commonly known as a water retaining platform, should be set around the opening where the bridge frame passes through the floor. The water retaining table can not only play the role of retaining water, but also prevent objects from falling into the electric well, and also play a role of decoration and beauty. [0003] The traditional c...
