Embodiment

[0050] Embodiment: A kind of concrete sill prefabricated assembly construction method, see figure 1 , including the following steps:

[0051] In this embodiment, the construction toilet such as figure 2 As shown, the prefabricated sill 2 is poured at the surrounding walls of the descending plate 1 of the toilet. The design thickness of the surrounding walls is 200mm, and the corner cast-in-place section 3 is set at the vertical junction of adjacent walls. Usually, the corner cast-in-place section 3 is used for Construction of structural columns.

[0052] 1) Support the bottom formwork.

[0053] First of all, the beam slab formwork, floor formwork support and steel bar binding around the toilet must be completed. This step adopts conventional construction methods, and the relative positions of each part are as follows: image 3 As shown, wherein the bottom formwork 11 of the lowering plate is located at the toilet side, the beam plate formwork 41 is supported on the lower ...

Abstract

The invention discloses a prefabricating construction method for a concrete flashing sill. The prefabricating construction method for the concrete flashing sill aims at solving the problem that duringexisting bathroom flashing sill construction, in a secondary casting or integrated casting construction method, the waterproof effect, the construction quality and the construction efficiency cannotbe considered simultaneously. In the technical scheme, the flashing sill is machined and prefabricated before casting construction, and after erecting of beam-slab formworks and a floor formwork on the periphery of a bathroom and binding of steel bars are completed, the prefabricated flashing sill is arranged on stirrups by placing supporting cushion blocks; bolt sleeves for positioning are arranged on the prefabricated flashing sill, thus a fall slab side formwork and a steel plate side formwork at a cast-in-situ section can be connected with the prefabricated flashing sill through bolts, accurate positioning and stability of the formworks are achieved, and accordingly it is ensured that the overall appearance quality, section size and position of concrete members are accurate; and meanwhile, the prefabricated flashing sill and a cast-in-situ floor can be constructed simultaneously, so that the tightness of the bonding face is guaranteed, the water seepage problem is avoided, and theconstruction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cantilever pouring construction, in particular to a construction method for prefabricated and assembled concrete canisters. Background technique [0002] In order to ensure the waterproof effect of the bathroom, concrete sills need to be poured in the lower part of the walls around the toilet descending plate. In the existing engineering construction, the method of secondary pouring is often adopted, that is, after the construction of the cast-in-place floor slab is completed, the concrete is poured in a secondary formwork. Although such a construction method is convenient for construction, due to the use of secondary pouring, construction joints will be produced at the junction of the two pourings, and water seepage is prone to occur in the humid environment of the bathroom. [0003] In order to solve the problem of easy water seepage caused by the secondary pouring construction of the sill, some people...
