Description

Technical Field

[0001] The utility model relates to the field of concrete component formwork fixing, in particular to a novel square tube back purlin. Background Art

[0002] At present, before pouring concrete components, the formwork needs to be fixed by fixing the back purlin (such as Figure 1 As shown), it is fixed by two round tubes and U-shaped clamps on the left and right sides;

[0003] However, this current fixing method is costly and inconvenient to install, thereby reducing work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0005] A novel square tube back purlin comprises two templates spaced apart from each other;

[0006] Square tubes are arranged horizontally on the left and right sides of the template, respectively. The square tubes are hollow I-shaped structures, and the concave surfaces of the square tubes are in contact with the template.

[0007] A plurality of through holes are arranged at intervals in the middle of the concave surface of the square tube, and screw rods are arranged through the through holes. Nuts are arranged on both ends of the screw rods and are in contact with the square tube.

[0008] As a further solution of the utility model: the outer diameter of the nut is less than or equal to the inner diameter of the concave surface of the square tube.

[0009] As a further solution of the utility model: a gasket is sleeved on the screw rod between the nut and the square tube.

[0010] As a further solution of the utility model: the shape of the through hole is any one of a circle and a rectangle or a combination thereof.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the present application only fixes the template through the hollow I-shaped square tubes on both sides. Compared with the traditional fixing method of two round tubes and U-shaped clips, the present application adopts a single square tube and a gasket, which can effectively reduce the cost. At the same time, it is more convenient in the fixing process, saves manpower and improves work efficiency.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 2-3 , a novel square tube back purlin, comprising two mutually spaced templates 1;

[0023] Square tubes 2 are disposed transversely on the left and right sides of the template 1, respectively. The square tubes 2 are hollow I-shaped structures, and the concave surfaces of the square tubes 2 are in contact with the template 1.

[0024] A plurality of through holes 3 are provided at intervals in the middle of the concave surface of the square tube 2 , and a screw rod 4 is provided through the through hole 3 . Nuts 5 are provided at both ends of the screw rod 4 and are in contact with the square tube 2 .

[0025] When in use, the screw 4 passes through the template 1 between the through holes 3 and is locked by the screw 4, thereby fixing the template 1, and then pouring concrete between the templates 1; the template 1 is fixed by the hollow I-shaped square tubes 2 on both sides. Compared with the traditional fixing method of two round tubes and U-shaped clips, the present application can effectively reduce costs, and at the same time is more convenient in the fixing process, saves manpower, and improves work efficiency.

[0026] As a further solution of the utility model: the outer diameter of the nut 5 is less than or equal to the inner diameter of the concave surface of the square tube 2.

[0027] The nut 5 can be inserted into the concave surface of the square tube 2, so that the contact surface between the nut 5 and the square tube 2 is more complete, thereby improving the stability of the fixation.

[0028] As a further solution of the utility model: a gasket 6 is sleeved on the screw rod 4 between the nut 5 and the square tube 2 respectively.

[0029] It can improve the connection stability between the nut 5 and the square tube 2 and avoid loosening; at the same time, in the actual construction site, the gasket 6 is lower in cost and easier to process than the traditional U-shaped clamp, and workers can complete the manufacturing by themselves, so the present application effectively reduces the cost compared with the traditional method.

[0030] As a further solution of the present invention: the shape of the through hole 3 is any one of a circle and a rectangle or a combination thereof.

[0031] The left and right positions of the screw rod can be adjusted conveniently according to actual construction conditions, thereby improving practicality.
