Problems solved by technology

[0003] At present, there are many types and special pieces of formwork steel supports between wall and column components, among which the formwork steel is divided into main flute and secondary flute, and the formwork steel support is completed through the cooperation of the main flute and the secondary flute. The versatility of the traditional steel formwork is poor, and the application of the formwork support in the thickness direction of the column hoop and the end of the shear wall requires additional processing of a large number of pull screws to complete the fixation. When setting the formwork at the end of the shear wall and the structural column formwork, it is necessary to set Many special parts, increased material and labor costs, and reduced construction efficiency and other issues

Embodiment 1

[0053] Such as figure 1 As shown, the three-dimensional structural diagram of the first formwork support 7, a novel L-shaped square steel formwork support used by a shear wall 19 and a structural column 17, includes a first square steel 1 and a second square steel 2 perpendicular to each other, so One end of the first square steel 1 is connected with one end of the second square steel 2 to form an L shape, and the new L-shaped square steel template support also includes a third-party steel parallel to the second square steel 2 3. One end of the third-party steel 3 is set on the first square steel 1, and the second square steel 2 and the third-party steel 3 are set on the same side of the first square steel 1;

[0054] Wherein, the distance between the second square steel 2 and the third-party steel 3 has a gap, the gap is used to fit the wall-through screw 4, the wall-through screw 4 is used to pass through the wall, and the wall-through For the specific setting position of s...

Embodiment 2

[0059] Such as image 3 As shown, the matching diagram of the first formwork support 7, the second formwork support 8, the third formwork support 9 and the fourth formwork support 10, the first formwork support 7, the second formwork support 8, the third formwork support 9 and the fourth formwork support The formwork supports 10 have the same structure, the four formwork supports are connected end to end, and the two adjacent formwork supports are perpendicular to each other, and cooperate with each other to form a square column hoop with an adjustable hollow part.

[0060] Such as Figure 4 as shown, Figure 4 It is a three-dimensional structural diagram of an adjustable column hoop, an adjustable column hoop, including four novel L-shaped square steel formwork supports used in the shear walls 19 and structural columns 17, that is, the first formwork support 7, the second formwork The support 8, the third formwork support 9 and the fourth formwork support 10, the four formw...

Embodiment 3

[0069] A construction method for an adjustable column hoop comprises the following steps:

[0070] Step 1, install the structural column 17 formwork according to the structural column 17 control line;

[0071] Step 2. Set the L-shaped square steel as a column hoop according to the formwork of the structural column 17, that is, set the first formwork support 7, the second formwork support 8, the third formwork support 9 and the fourth formwork support 10 to form an adjustable column hoop;

[0072] Step 3: According to the size of the structural column 17, fix the first lock 11, the second lock 12, the third lock 13 and the fourth lock 14 on the corresponding first formwork support 7, second formwork support 8, and third formwork support 9 And the position on the fourth template support 10;

[0073] Step 4, fine-tuning the positions of the first formwork support 7, the second formwork support 8, the third formwork support 9 and the fourth formwork on the structural column 17; ...

Abstract

The invention relates to shear wall and structure column formwork supports, in particular to a novel L-shaped square steel formwork support, an adjustable column hoop and a construction method. The novel L-shaped square steel formwork support is provided with a first square steel and a second square steel which are perpendicular. One end of the first square steel is connected with one end of the second square steel to form an L shape. Meanwhile, the novel L-shaped square steel formwork support is provided with a third square steel parallel to the second square steel. One end of the third square steel is arranged on the first square steel. The second square steel and the third square steel are arranged on the same side of the first square steel. A gap is formed between the second square steel and the third square steel of the L-shaped square steel formwork support and matched with through-wall screw rods. The novel L-shaped square steel formwork support can be used for replacing main rib components of traditional shear walls and structure columns and can be universal for all parts of structure columns, shear walls and cavity internal and external corners. The uniformity of the supports is improved.

Description

technical field [0001] The invention relates to a formwork support for a shear wall and a structural column, in particular to a novel L-shaped square steel formwork support, an adjustable column hoop, a construction method for an adjustable column hoop, and a shear wall end formwork support And a construction method for formwork support at the end of a shear wall. Background technique [0002] With the rapid development of the modern construction industry, the scale of construction in various parts of the country continues to expand, and various construction turnover materials are increasing day by day. In addition, the current shortage of forest resources in my country and the requirements for ecological environmental protection are getting higher and higher. It is imperative to make material properties and shape weekly materials. In order to save resources, improve work efficiency, and meet the requirements of the visual quality, flatness, and verticality of the main concr...
