Problems solved by technology

[0002] The phenomenon of grout leakage and rot at the root of concrete shear wall pouring has always been prominent, but the traditional method of root sealing cement mortar, its strength cannot meet the requirements of concrete pouring, the concrete will separate and crack as soon as it is vibrated, and the formwork is difficult to remove after pouring , resulting in affecting the construction progress and quality, and the bonding performance of cement mortar and aluminum formwork is poor
[0003] Therefore, there are above-mentioned inconveniences and problems in the known concrete aluminum formwork support mode

Embodiment 1

[0039] The device for preventing grout leakage at the root of the concrete aluminum formwork of the present invention is a quick-detachable aluminum formwork used for concrete pouring of a shear wall, including angle aluminum, a first angle iron, and a second angle iron.

[0040] see now figure 1 and figure 2 , figure 1 It is a schematic diagram of the use state of the device for preventing grout leakage at the root of the concrete aluminum formwork according to the embodiment of the present invention, figure 2 for figure 1 Sectional view of A-A in Fig. As shown in the figure, the angle aluminum 2 is an equilateral aluminum alloy angle aluminum with a specification of ∠65*65*4, and a number of bolt holes are arranged on one side of the angle aluminum.

[0041] The first angle iron 3 is an equilateral angle iron of specification ∠50*50*3, and a number of bolt holes are arranged on one side of the first angle iron, and the first angle iron is arranged on the right angle in...

Embodiment 2

[0044] A method for using a device for preventing grout leakage at the root of concrete aluminum formwork, comprising the following steps:

[0045] a. Set the 90-degree right-angled side of the aluminum formwork 1

[0046] The aluminum formwork 1 close to the root of the wall of the quick-release aluminum formwork poured with concrete for the shear wall is bent to the outside of the wall to form a 90-degree right-angle side, and a number of bolt holes are arranged on the plane of the right-angle side.

[0047] b. Install the angle aluminum

[0048] The installed angle aluminum 2 is an equilateral aluminum alloy angle aluminum with a specification of ∠65*65*4, and a number of bolt holes are arranged on one side of the angle aluminum, so that the angle aluminum bolt holes match and align with the aluminum formwork bolt holes.

[0049] c. Install the first angle iron

[0050] The first angle iron 3 is an equilateral angle iron of specification ∠50*50*3, and a number of bolt hol...

Abstract

A device for preventing slurry leakage at the root of a concrete aluminum formwork is used for the fast-disassembled aluminum formwork for shear wall concrete pouring, comprises angle aluminum, firstangle iron and second angle iron, and is characterized in that the angle aluminum (2) is equilateral aluminum alloy angle aluminum with the specification of the angle 65*65*4, the first angle iron (3)is equilateral angle iron with the specification of the angle 50*50*3, a spring (5) is arranged between a first spring baffle (8) and a second spring baffle (9), the second angle iron (4) is equilateral angle iron with the specification of the angle 40*40*4, one edge of the second angle iron is inserted into a gap between the first angle iron and the angle aluminum, and thus the device for preventing slurry leakage at the root of the concrete aluminum formwork is achieved. The device for preventing slurry leakage at the root of the concrete aluminum formwork and a using method thereof have the advantages that the device for preventing slurry leakage at the root of the concrete aluminum formwork is simple in structure, ingenious in design and convenient to use, the performance of preventing slurry leakage at the root of the concrete aluminum formwork is excellent, the construction efficiency is improved, and labor and materials are saved.

Description

technical field [0001] The invention relates to a device for preventing grout leakage at the root of an aluminum concrete formwork, in particular to a device for preventing grout leakage at the root of an aluminum concrete formwork and a method for using the same. Background technique [0002] The phenomenon of grout leakage and rot at the root of concrete shear wall pouring has always been prominent, but the traditional method of root sealing cement mortar, its strength cannot meet the requirements of concrete pouring, the concrete will separate and crack as soon as it is vibrated, and the formwork is difficult to remove after pouring , resulting in affecting the construction progress and quality, and the bonding performance of cement mortar and aluminum formwork is poor. [0003] Therefore, there are above-mentioned inconveniences and problems in the known concrete aluminum formwork support mode. Contents of the invention [0004] The object of the present invention is ...
