Description

TECHNICAL FIELD

[0001] The present application relates to the field of materials and equipment for formwork engineering in building construction, in particular to a sun angle reinforcing secondary keel based on a wall column formwork. BACKGROUND

[0002] Before pouring concrete walls and columns, wall column formwork needs to be assembled according to design drawings. In the prior art, more than 90% of the wall column formwork assembly is completed using wooden formwork and iron nails, iron wire and wood. During construction, the secondary keel and the wall column formwork are fixed at the sun angle position of the wall and column using iron nails or iron wire. The degree of fixation at the sun angle position is mainly determined by the iron nails and the related external secondary keel and reinforcing back ridge support structure. During pouring and grouting, the wall column formwork fixed by iron nails is easily deformed due to the large outward pressure during concrete pouring and vibration, which eventually leads to leakage and honeycomb quality accidents. This not only increases the difficulty of construction, but also causes the edge of the wrapped formwork to crack and damage the wrapped formwork, reducing the turnover frequency of the formwork and making it difficult to achieve the quality of non-plastering of the formed wall and column.

[0009] As preferred, the two adjacent external corner reinforcing sub-bases are fixed as a whole by an external corner sub-base inner connecting pipe fixed at two ends of the two external corner reinforcing sub-bases and a pin penetrating the two triangular connecting holes.

[0010] As preferred, one side surface of the edge-covered template body is against one of the inner corner surfaces of the two external corner square tubes, and the other side surface adjacent to the one side surface is against the other of the inner corner surfaces of the two external corner square tubes.

[0028] Example 1

[0029] like Figure 1 As shown, the external corner reinforcement secondary purlin based on the wall column formwork includes two groups of mutually perpendicular template parts 100 arranged at the external corners of the wall and column, and also includes a external corner reinforcement secondary purlin 200 fixed to the two groups of mutually perpendicular template parts 100.

[0030] like Figure 2 As shown, the template portion 100 consists of an edge-wrapping template portion and an edge-wrapped template portion; the edge-wrapping template portion is formed by splicing together several rectangular edge-wrapping template bodies 101; the edge-wrapped template portion is formed by splicing together several rectangular edge-wrapped template bodies 101.

[0031] The left side of the edge of the template body 101 and the right side of the edge of the template body 101 are respectively provided with a plurality of L-shaped hinges 102; the upper side and / or the lower side of the center of the template body 101 is provided with a template connecting block 103, and the two template bodies 101 are integrally connected by a pin inserted through the pin hole in the center of the connecting block 103.

[0032] When setting, the distance between the L-shaped hinge and the left side of the edge of the template body is 3.6 cm, and the distance between the L-shaped hinge and the right side of the edge of the template body is 1.7 cm. The L-shaped hinge is convenient to cooperate with the external corner reinforcing secondary batten, so that the template body can be placed on the corner of the external corner reinforcing secondary batten.

[0033] A plurality of U-shaped screw holes 104 are arranged on the side edge of the template body 101 away from the external corner reinforcing secondary batten 200.

[0034] As shown in Figure 3 The external corner reinforcing secondary batten 200 is composed of two mutually perpendicular external corner square tubes 201, a reinforcing L-shaped plate 203 fixedly attached to the outer corner surfaces of the two external corner square tubes 201, a plurality of triangular connecting plates 204 fixedly attached to the outer corner surfaces of the two external corner square tubes 201, a plurality of external corner fixing holes 202 arranged perpendicularly on the outer corner surfaces of the two external corner square tubes 201, and a triangular connecting hole 205 vertically penetrating the triangular connecting plate 204; the distance between the two adjacent triangular connecting plates is about 600 mm.

[0035] The two external corner square tubes are integrally connected by welding, and a gap of about 3 mm is required between the two external corner square tubes during welding, which has two purposes: one is to facilitate the observation of the tightness of the external corner reinforcing secondary batten during installation, and the other is to facilitate the welding process, improve the efficiency and convenience of welding.

[0036] As shown in Figure 5 In actual use, the reinforcing L-shaped plate can also be replaced by a triangular connecting plate, so that the reinforcing L-shaped plate does not need to be produced again, reducing the number of product accessories and further improving the production efficiency and use effect of the product.

[0037] The two adjacent external corner reinforcing secondary battens 200 are integrally connected by an external corner secondary batten inner connecting pipe 206 fixed at both ends of the two external corner reinforcing secondary battens 200 and a pin penetrating the two triangular connecting holes 205.

[0038] The structure of the external corner secondary batten inner connecting pipe is as shown in Figure 4As shown, it is welded by two existing inner connecting pipes, and its structure and use mode are prior art, and the person skilled in the art can set and use it without creative labor according to the above description, and thus no further description is given here.

[0039] The side surface of the edge-covered formwork body 101 abuts against one of the inner side corner surfaces of the two male corner square pipes 201, and the surface adjacent to the side surface abuts against the other of the inner side corner surfaces of the two male corner square pipes 201; one side surface of the edge-covered formwork body 101 abuts against the other surface adjacent to the side surface of the edge-covered formwork body 101, and the other surface adjacent to the side surface of the edge-covered formwork body 101 abuts against one of the inner side corner surfaces of the two male corner square pipes 201.

[0041] The formwork part 100 is fixed on the male corner reinforcing secondary batten 200 by the pin that penetrates the L-shaped hinge 102 and the male corner fixing hole 202 adjacent to the L-shaped hinge 102 at the same time.

[0042] In the setting, the length of the male corner reinforcing secondary batten can be adjusted according to actual needs, and the length of the lowermost male corner reinforcing secondary batten is generally determined according to the actual needs of different structure parts with a layer height of 2.9 meters, and the upper part needs to be set according to the actual wall and column height to select the corresponding length of the male corner reinforcing secondary batten.

[0043] In order to improve the standardization of the product, the size of each part is limited, so as to facilitate the cooperation between the products, and also effectively reduce the size of the sawing required during the assembly of the product, further reducing the loss of the parts caused by the sawing, thereby reducing the construction cost; the standard size of each part is as follows:

[0045] But in actual construction, according to the actual demand, the width of the sun corner formwork is increased while the width of the shadow corner formwork is increased; the width of the main body of the formwork wrapped by the wall head formwork is the size of the wall width head plate minus 2mm, the width of the main body of the formwork wrapped is determined according to the actual situation; the main body of the formwork wrapped by the square column is the width of the square column plus 28mm, the width of the main body of the formwork wrapped is the width of the square column minus 2mm, the standard height of the lower end is 1.8 meters, and the top end formwork needs to be determined according to the actual demand.

[0046] The size of the sun corner reinforcing secondary keel is:

[0058] 3m floor height: 100mm 98.5mm;

[0059] 3.1m floor height: 200mm 185mm;
