Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a post-casting strip forming structure which does not require chiseling. Background Art

[0002] The construction of houses is increasingly tending to be large in area, multi-functional and comfortable to live in. The main material of houses is reinforced concrete. Based on the shrinkage characteristics of concrete, in order to prevent concrete cracking, post-cast strips must be set in large areas.

[0003] At present, during the construction of post-cast strips, steel mesh and water-stop steel plates are generally installed at the joints between the post-cast strips and the concrete on both sides, so as to isolate the post-cast strips from the concrete on both sides when the concrete on both sides is poured. When the concrete strength on both sides reaches more than 50%, the steel mesh and loose concrete at the joints need to be chiseled, generally using an electric hammer or manually using a hand hammer and chisel, until the complete rough stone surface is exposed.

[0004] The above-mentioned post-cast strip construction technology has the problems of long construction period, small chiseling working surface resulting in inconvenient operation, difficulty in cleaning up the chiseled garbage, and chiseling noise pollution. Utility Model Content

[0005] In view of this, the utility model provides a post-casting strip forming structure that does not require chiseling. There is no need to chisel the wire mesh and loose concrete at the joints. The operation is simple, the construction efficiency is improved, the concrete interface is orderly, and the structural quality is improved.

[0006] The utility model is realized by the following technical solutions:

[0007] A post-casting strip forming structure that does not require chiseling, the peripheral structure of which is: a bottom template, a bottom layer steel mesh and a surface layer steel mesh;

[0008] Let the two perpendicular directions on the horizontal plane be horizontal and vertical respectively;

[0009] The bottom steel mesh is arranged on the bottom formwork through a concrete protective pad; the bottom steel mesh is composed of a number of steel bars arranged in a grid shape in the horizontal and vertical directions;

[0010] The surface steel mesh is tied and fixed at a set distance above the bottom steel mesh and parallel to the bottom steel mesh; the surface steel mesh is composed of a number of steel bars arranged in a grid shape in the horizontal and vertical directions;

[0011] The post-casting strip forming structure comprises: a vertical plate and an attachment strip;

[0012] The vertical plate is a long plate-shaped structure, fixedly arranged between the bottom steel mesh and the surface steel mesh, and vertically arranged at the joint between the post-casting strip and the concrete, and the length direction of the vertical plate is along the length direction of the joint;

[0013] The attachment tape is fitted on the surface of the vertical plate facing the concrete, and the surface of the attachment tape facing the concrete is provided with a concave-convex texture.

[0014] Furthermore, the post-cast strip forming structure also includes a support component for supporting and fixing the opposing plates.

[0015] Furthermore, the supporting assembly includes wooden planks and supporting rods. The wooden planks are arranged on the surface of the vertical board facing the post-cast strip along the length direction of the vertical board. One end of the supporting rod is supported on the wooden planks, and the other end is supported on the bottom formwork located in the post-cast strip, so that the vertical board is vertically arranged at the joint between the post-cast strip and the concrete.

[0016] Furthermore, a plurality of "V"-shaped notches are provided at the top and bottom of the vertical plate along the length direction. The "V"-shaped notches at the top match one-to-one with the surface steel mesh and all transverse steel bars or all longitudinal steel bars, and the "V"-shaped notches at the bottom match one-to-one with all transverse steel bars or all longitudinal steel bars of the bottom steel mesh.

[0017] Furthermore, the attachment tape adopts a chiseling-free grout-stopping tape.

[0018] Furthermore, the attachment tape is made of bubble film.

[0019] Beneficial effects:

[0020] (1) The utility model can prevent slurry concrete from entering the post-cast strip when pouring concrete on both sides of the post-cast strip by providing a vertical plate and an attachment strip at the joint between the post-cast strip and the concrete. When the vertical plate and the attachment strip are removed, the surface of the attachment strip facing the concrete is provided with a concave-convex texture, which can form a regular rough surface on the surface of the concrete. The post-cast strip is in the shape of a straight strip, and there is no need to chisel away excess loose concrete. This not only improves the quality of the concrete interface at the joint, but also improves construction efficiency, reduces noise, and reduces labor costs. In addition, the vertical plate and the attachment strip can be reused, which reduces construction costs and improves construction benefits.

[0021] (2) The arrangement of the support assembly of the utility model facilitates the disassembly of the attachment belt and the vertical plate, avoids the need to chisel the wire mesh at the joint, reduces noise, facilitates cleaning, and improves construction efficiency.

[0022] (3) The "V"-shaped notch of the present invention can not only ensure that the slurry concrete does not enter the post-cast zone, but also further ensure the stability of the vertical plate installation.

[0023] (4) The attachment belt of the utility model adopts a chiseling-free stop-slurry belt, which is made of a polymer fiber material, has high durability and high wear resistance, and can be reused. BRIEF DESCRIPTION OF THE DRAWINGS
