Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments may be combined with each other without conflict.
Referring to fig. 1 and 2, in one embodiment of the present application, a pull tab 100 is provided for reinforcing a form. The pull tab 100 includes an embedded portion 10, a connecting portion 20, and a stopper portion 30. The connecting portion 20 has two for connecting the templates. The two connecting portions 20 are respectively connected to both ends of the embedded portion 10. The two connecting portions 20 are disposed in parallel. An included angle w is formed between the surface of each connecting portion 20 and the surface of each embedded portion 10. The angle w is obtuse. The limiting part 30 is arranged at the end part of the embedded part 10. One side of the limiting part 30 close to the connecting part 20 is provided with a limiting surface 31. The locating surface 31 is perpendicular to the locating surface of the connecting part 20. As an exemplary example, the embedded portion 10 and the connection portion 20 are both in a straight strip shape, and the length extending direction is located in the same plane, and the connection portion 20 forms an included angle w at two ends of the embedded portion 10 through a bending process. It will be appreciated that the attachment portion 20 is provided with mounting holes 21 to attach the formwork side walls by means of dowel pins or the like.
In some embodiments, as shown in fig. 2, two sides of the two ends of the embedded portion 10, which are away from each other, are respectively provided with a limiting portion 30. Each limiting portion 30 is located within the included angle w, that is, each limiting portion 30 is located on one side of the embedded portion 10 facing the connecting portion 20 of the corresponding end. The limiting surface 31 of each limiting part 30 is used for contacting the formwork on the corresponding side of the connecting part 20 to limit the formwork, and the formwork on the side is prevented from being inclined inwards to be displaced so as to influence the cement pouring quality.
In other embodiments, as shown in fig. 3, two sides of the same end of the embedded portion 10 that are away from each other are respectively provided with a limiting portion 30, that is, one of the limiting portions 30 is located in the included angle w, and the other limiting portion 30 is located in the supplementary angle of the included angle w, so that two sides of the connecting portion 20 are both provided with the limiting portions 30. The limiting surfaces 31 of the two limiting parts 30 can respectively contact the formworks on the two sides of the connecting part 20 to limit the two formworks, so that the formworks on the two sides of the connecting part 20 are prevented from being inclined inwards and shifted to influence the cement pouring quality.
As an exemplary example, as shown in fig. 1 to 3, the position-limiting portion 30 has a triangular plate structure, a bevel edge of the position-limiting portion 30 is welded to the pre-buried portion 10, a position-limiting surface 31 is formed on a side of the position-limiting portion 30 close to the connecting portion 20, the position-limiting surface 31 is connected to a joint of the pre-buried portion 10 and the connecting portion 20, and further, the position-limiting portion 30 is welded to the pre-buried portion 10 perpendicularly, that is, a plane of the position-limiting portion 30 is perpendicular to planes of the pre-buried portion 10 and the connecting portion 20. It is understood that in other embodiments, the limiting portion 30 may have other structures, such as a block-shaped or column-shaped structure.
In the template assembly operation, the lateral wall between two relative templates has the condition of just right, can't use ordinary czochralski blade to consolidate, and the pulling-on piece 100 is through connecting portion 20 and the pre-buried portion 10 that has the contained angle for the not just right position of two relative templates still can be connected and consolidate, and spacing face 31 through spacing portion 30 limits the distance between two templates, avoids the slope or the side of two templates to move the scheduling problem, and then has realized the purpose that promotes template reinforcing efficiency and quality.
Referring to fig. 4 and 5, in one embodiment of the present application, a formwork system 200 for pouring cement to form a wall surface is also provided. Template system 200 includes a reentrant template 210, a planar template 220, and a pull tab 100. The internal corner form 210 is used to form an internal corner of a wall, and the flat form 220 is disposed opposite to a right-angled surface of the internal corner form 210 to form an external corner surface of the wall. Because the wall thickness causes the problem that the external corner face is longer than the internal corner face, one side wall of the plane template 220 is not aligned with the side wall of the internal corner template 210 (or the side wall of any template), and depending on the structure that an included angle is formed between the connecting part 20 at the two ends of the pull tab 100 and the embedded part 10, the connecting part 20 can be respectively connected with the side wall of the plane template 220 and one side wall of the internal corner template 210, so that the positions, which are not aligned, of the internal corner template 210 and the plane template 220 forming the external corner can still be connected and reinforced. After connection, the limiting surface 31 contacts the surfaces of the internal corner formwork 210 and the plane formwork 220 to limit the distance between the internal corner formwork 210 and the plane formwork 220, and prevent the internal corner formwork 210 and the plane formwork 220 from inclining inwards to ensure the pouring quality.
Further, to facilitate the splicing of other wall forms, the other side wall of the flat wall form 220 is opposite to the side wall of the inside corner form 210, so as to connect other wall forms 230. Template system 100 further includes a straight pull tab 240. The flat template 220 is attached to the side wall of the inside corner template 210 by the straight pull tab 240 without attaching the side wall of the pull tab 100 (i.e., the side wall facing the side wall of the inside corner template 210). At this time, the pulling piece 100, the planar formwork 220 and the straight pulling piece 240 form a right triangle structure, which can improve the stability of the planar formwork 220 relative to the internal corner formwork 210, thereby improving the pouring quality.
In other embodiments, as shown in fig. 6, both sidewalls of the flat template 220 are not opposite to the sidewalls of the inside corner template 210, i.e. both sides of the flat template 220 cannot be connected to the sidewalls of the inside corner template 210 by the straight pull tab 240, and at this time, both opposite sides of the flat template 220 can be connected to the same sidewalls of the inside corner template 210 by two pull tabs 100. Similarly, the pulling piece 100, the plane template 220 and the straight pulling piece 240 form a triangular structure, the structure can also improve the stability of the plane template 220 relative to the internal corner template 210, and in this case, the two sides of the plane template 220 are limited by the limiting surfaces 31, so that the plane template 220 is more stable, and the pouring quality is further improved.
In some embodiments, the template system 100 further includes a set of male corner templates 250. The external corner template set 250 includes two external corner face templates 251 and a right-angle plate 252. Two sides of the right-angle plate 252 are respectively connected with an external corner face template 251 to form an external corner structure of the wall body. The two external corner face templates 251 are respectively arranged opposite to the two right-angle faces of the internal corner template 210. The side of each external corner face template 251, which faces away from the right-angle plate 252, is connected with the plane template 220, and the connection side is the side of the plane template 220 not opposite to the internal corner template 210.
In some embodiments, template system 100 is symmetrically arranged along the angular bisector of inside corner template 210, i.e., the width of two outside corner face templates 251 is the same, the width of two flat surface templates 220 is the same, and the width of two right angle faces of inside corner template 210 is the same.
In some embodiments, as shown in fig. 4, a plurality of straight pull tabs 240 and pull tabs 100 are arranged between the inside corner mold plate 210 and the flat mold plate 220 along the height direction, and the straight pull tabs 240 and the pull tabs 100 are located at the same height in a one-to-one correspondence, so that the number of pin pieces is reduced to facilitate the splicing operation. In other embodiments, the straight pull tab 240 and the pull tab 100 may be alternately arranged in the height direction.
By way of illustrative example, the distance between the external corner face form 251 or the planar form 220 and the internal corner form 210 is greater than 400mm to form a wall greater than 400 mm.
To sum up, the template system 200 can connect and reinforce the positions of the internal corner template 210 and the plane template 220 forming the external corner, which are not opposite to each other, through the pull tab 100, and then limit the distance between the internal corner template 210 and the plane template 220 through the limiting surface 31 of the limiting portion 30, so as to avoid the problems of the inclination or lateral movement of the plane template 220 and the internal corner template 210, and further achieve the purpose of improving the template reinforcing efficiency and quality.
In addition, those skilled in the art should recognize that the foregoing embodiments are illustrative only, and not limiting, and that appropriate changes and modifications to the foregoing embodiments may be made within the spirit and scope of the present disclosure.
