Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] This embodiment is described by taking a concrete joint to be poured as an example. The width of the joint is 20 mm, and a formwork needs to be placed at the joint position during pouring. The template of this embodiment includes a sheet-like skeleton 1, such as figure 1 with 2 As shown, the skeleton 1 is a sheet structure made of PVC material. There are a plurality of through holes 2 evenly distributed on the skeleton 1. The wall thickness of the through holes 2 is 5 mm. The through holes 2 of this embodiment are regular hexagonal structures. The side length of the hole 2 is 20 mm, and the whole skeleton 1 has a honeycomb structure. The thickness of the skeleton 1 is 14mm.

[0036] The through hole 2 is filled with a first filling structure 3 that can expand after absorbing water, such as figure 2 with 3 As shown, the su...

Abstract

The invention relates to the technical field of building construction structures, in particular to a water-stopping form board. The water-stopping form board comprises a flaky framework and is characterized in that a plurality of through holes are evenly distributed in the framework, first filling structures which can expand after water absorption are filled into the through holes, the first filling structures filled into the through holes and the framework form a planar form board structure without pores in the surface, and a waterproof structure with time effectiveness wraps the outer side of the form board formed by the framework and the first filling structures. The water-stopping form board is simple in structure, convenient in mounting and pouring, capable of greatly increasing concrete pouring efficiency, capable of increasing the water stopping effect at concrete gaps and worthy of popularization and does not need an additional new water-stopping structure.

Description

technical field [0001] The invention relates to the technical field of building construction structures, in particular to a water-stop formwork. Background technique [0002] The existing concrete pouring process is mainly divided into the following types: [0003] 1. During the concrete construction of the bottom slab, the conventional method is to erect the joint material first, the formwork is close to the joint material, and then the concrete block is poured first, and the formwork is removed after the concrete reaches a certain strength, and then the post-cast concrete construction is carried out; or Asphalt fir boards are used as formwork and as parting materials at the same time; [0004] 2. The vertical water-stop at the joints of hydraulic structures on the soil foundation generally adopts the method of water-stop wells. During construction, the formwork of the first pouring block can be removed after pouring is completed, but the formwork of the last pouring block...
