Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a formwork connector and a formwork system. Background Art

[0002] During construction, the shapes of buildings are diverse and as the industry's requirements for buildings become higher and higher, different angles are required in many non-standard buildings. The templates are connected by connectors. In order to form different angles in the building, the connectors are usually bent by equipment to the same angle as the building corner. Then, the connectors are connected to the templates through connectors, so that the two adjacent templates form a corresponding angle. The connectors need to be bent at a corresponding angle according to the angle, but the angle of the current equipment bending connectors is fixed, which means that after the connectors are bent by the equipment, additional adjustments are required, affecting construction efficiency. Summary of the invention

[0003] In view of this, it is necessary to provide a template connector and a template system that can accurately connect two templates according to the angle between the two templates.

[0004] The embodiment of the present application provides a template connector, including a main body and two fixing parts. The main body includes a first side, a second side and a third side connected to each other, the first side and the second side form a first angle, the second side and the third side form a second angle, and the first angle and the second angle are both less than 90°. One of the two fixing parts is connected to the first side, and the other is connected to the third side, and the angle between the fixing part and the main body is greater than or equal to 85° and less than or equal to 95°.

[0005] The fixing part is used to connect with the template. According to the spacing between the two templates and the different template angles, template connectors of different sizes and different first and second angles are produced accordingly, and the template connector can be installed on the two templates by bending the fixing part 85° to 95°. Therefore, facing different template angles, the angle between the fixing part and the main part is roughly 90°, and can be directly formed by stamping and other methods. Therefore, the production of the template connector is simple and high-precision, and the template connector can accurately connect the two templates.

[0006] In at least one embodiment, the main body is trapezoidal in shape.

[0007] The main body is trapezoidal, so that there is a distance between the two fixing parts, which is convenient for installing the template connecting parts.

[0008] In at least one embodiment, the length of the second side is greater than or equal to 130 mm and less than or equal to 230 mm.

[0009] The length of the second side within the range can ensure that the main body has sufficient strength and that there is a sufficient distance between the two fixing parts.

[0010] In at least one embodiment, the main body further includes a fourth side, the fourth side is connected to the first side and the third side, and is parallel to the second side. The difference between the length of the second side and the length of the fourth side is greater than or equal to 25 mm and less than or equal to 50 mm.

[0011] Not only can the first angle and the second angle be within a suitable range, but also a suitable spacing can be left between the shortest distances of the two fixing parts, which is convenient for installation.

[0012] In at least one embodiment, the angle between the fixing portion and the main body portion is 90°.

[0013] The angle between the fixing portion and the main body is 90°, and the fixing portion can be directly formed by bending it 90° by stamping or other methods during production, so that the production of the template connector is simple and quick.

[0014] In at least one embodiment, the first angle and the second angle are both greater than or equal to 50° and less than or equal to 80°.

[0015] The ranges of the first angle and the second angle are moderate, so that the template connector can be stably connected to the template.

[0016] In at least one embodiment, the fixing portion includes a first fixing edge, a second fixing edge, a third fixing edge and a fourth fixing edge. The first fixing edge overlaps with the first edge or the third edge. The second fixing edge is connected to the second edge. The fourth fixing edge is connected to the fourth edge and is parallel to the second fixing edge. The third fixing edge is perpendicular to and connected to the second fixing edge and the fourth fixing edge.

[0017] The second fixed edge is parallel to the fourth fixed edge, and the third fixed edge is perpendicular to the second fixed edge and the fourth fixed edge respectively, so that in template connectors of different sizes, the angle between the first fixed edge and the first edge and the angle between the second fixed edge and the second edge can always remain consistent, which can reduce the production difficulty of the template connector and improve the size and accuracy of the template connector.

[0018] In at least one embodiment, the length of the second fixed side is greater than or equal to 45 mm, and less than or equal to 55 mm.

[0019] The length of the second fixed edge is moderate, which can not only allow enough space for punching holes in the fixed part, but also minimize the use of materials.

[0020] In at least one embodiment, the fixing portion is provided with a connecting hole, and the distance between the center of the connecting hole and the third fixing edge is greater than or equal to 15 mm and less than or equal to 25 mm.

[0021] The position of the connection hole is determined according to the fixing part, which is convenient for punching the fixing part.

[0022] An embodiment of the present application also provides a formwork system, comprising two aluminum formworks, a wooden formwork and a connecting piece, wherein the formwork connecting piece connects the two aluminum formworks, and the angle between the two aluminum formworks is the sum of the first angle and the second angle, and the formwork is arranged on the formwork connecting piece and is located between the two aluminum formworks.

[0023] The angle between the two aluminum templates is the sum of the first angle and the second angle. When facing different angles between the two aluminum templates, corresponding template connectors are produced, and the angles between the fixed part and the main part of different template connectors are all 90°, making it easier to produce high-precision template connectors. The space between the two aluminum templates is supplemented by wooden templates, and the aluminum template is combined to reduce construction costs.

[0024] The template connector and template system of the present application enable the template connector to connect two aluminum templates with template angles through the first angle and the second angle, and the angle between the fixed part and the main body is 90°, which is simple to produce and has high dimensional accuracy. There is no need to repeatedly adjust the angle between the fixed part and the main body, which is convenient for improving construction efficiency. In addition, the angle between the first fixed edge and the first edge, and the angle between the second fixed edge and the second edge will not change according to the size of the template connector, so that when the template connector is produced by laser cutting, the angle at which the laser cutting rotates remains unchanged, which can not only improve the dimensional accuracy of the template connector, but also reduce the difficulty of producing the template connector.

[0047] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0050] Some embodiments of the present application provide a template connector, including a main body and two fixed parts. The main body includes a first side, a second side and a third side connected to each other, the first side and the second side form a first angle, the second side and the third side form a second angle, and the first angle and the second angle are both less than 90°. One of the two fixed parts is connected to the first side, and the other is connected to the third side, and the angle between the fixed part and the main body is greater than or equal to 85° and less than or equal to 95°. The fixed part is used to connect with the template, and according to the spacing between the two templates and the template angle, template connectors of different sizes and different first angles and second angles are produced accordingly, and the fixed part is bent 85° to 95°, so that the template connector can be installed on the two templates. Therefore, facing different template angles, the angle between the fixed part and the main body is approximately 90°, so the production of the template connector is simple and high-precision, and the template connector can accurately connect the two templates.

[0051] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0052] See also Figure 1 and Figure 2 In one embodiment, a template connector 100 is provided for connecting templates, including a main body 10 and two fixing parts 20, the two fixing parts 20 are respectively located at two ends of the main body 10, the main body 10 includes a first side 11, a second side 12 and a third side 13 connected to each other, the second side 12 is located between the first side 11 and the third side 13. The first side 11 and the second side 12 form a first angle 15, the second side 12 and the third side 13 form a second angle 16, and the first angle 15 and the second angle 16 are both less than 90°.

[0053] The fixing portion 20 is integrally formed with the main body 10, and one of the fixing portions 20 is connected to the main body 10 through the first edge 11, and the other fixing portion 20 is connected to the main body 10 through the third edge 13. The angle between the fixing portion 20 and the main body 10 is greater than or equal to 85° and less than or equal to 95°. In a preferred embodiment of the present application, the angle between the fixing portion 20 and the main body 10 is 90°. When two templates are connected by the template connector 100, the two fixing portions 20 are respectively connected to different templates. Due to the existence of the first angle 15 and the second angle 16, a template angle is formed between the two templates, and the angle of the template angle is the sum of the first angle 15 and the second angle 16.

[0054] When producing the template connector 100, the template connector 100 is cut according to a predetermined size, and then the fixing portion 20 is bent 90° along the first side 11 and the third side 13 to form the template connector 100. Regardless of the angle of the template angle formed by the two templates, the fixing portion 20 only needs to be bent 90°, thereby improving the accuracy of the template connector 100, so that the template connector 100 can connect the templates according to the predetermined template angle.

[0055] In one embodiment, the main body 10 is in a trapezoidal shape, so that there is a sufficient distance between the two fixing portions 20 to facilitate the installation of the template connector 100 .

[0056] It is understandable that, in other embodiments, the main body 10 may also be triangular, which can save the material usage of the template connector 100 .

[0057] In one embodiment, the main body 10 also includes a fourth side 14, which is parallel to the second side 12 and located between the first side 11 and the third side 13, one end of the fourth side 14 is connected to the first side 11, and the other end of the fourth side 14 is connected to the third side 13.

[0058] Specifically, the length of the second side 12 can be 157 mm, 176 mm, 201 mm, etc. The length is greater than or equal to 130 mm and less than or equal to 230 mm, so that the main body 10 can maintain a better strength while being able to be made into a corresponding size according to the distance between the two templates.

[0059] The length of the second side 12 is greater than the length of the fourth side 14, and the difference between the length of the second side 12 and the length of the fourth side 14 can be 29mm, 45mm, 49mm, etc., which is greater than or equal to 25mm and less than or equal to 50mm. This allows the first angle 15 and the second angle 16 to be within a suitable range, and also allows a suitable spacing to be left between the shortest distances of the two fixing portions 20, which is convenient for installation.

[0060] In one embodiment, the first angle 15 and the second angle 16 are different, and the first angle 15 and the second angle 16 are determined by the template angle between the two templates and the distance between the two templates. The template connector 100 of corresponding size is produced by the position and size of the two templates, which can improve the accuracy of the template connector 100.

[0061] Specifically, the first angle 15 can be 60°, 61°, 75°, etc., which is greater than or equal to 50° and less than or equal to 80°. The second angle 16 can be 63°, 64°, 71°, etc., which is greater than or equal to 50° and less than or equal to 80°.

[0062] The fixing portion 20 includes a first fixing edge 21, a second fixing edge 22, a third fixing edge 23 and a fourth fixing edge 24. The first fixing edge 21 coincides with the first edge 11 or the third edge 13, the second fixing edge 22 is connected to the second edge 12, the fourth fixing edge 24 is connected to the fourth edge 14, the second fixing edge 22 is parallel to the fourth fixing edge 24, and the third fixing edge 23 is connected to and perpendicular to the second fixing edge 22 and the fourth fixing edge 24, so that the fixing portion 20 is in a trapezoidal shape.

[0063] Thus, when the template connector 100 is in an unfolded state without being bent, the angle between the first fixed side 21 and the first side 11 and the angle between the fourth fixed side 24 and the fourth side 14 in the template connectors 100 of different sizes can remain unchanged. The template connector 100 is formed by laser cutting and then stamping and bending. Therefore, in the process of forming the template connectors 100 of different sizes by laser cutting, the laser cutting rotation angle remains the same. Therefore, the process of producing the template connectors 100 of different sizes is simple and fast, and the size accuracy of the produced template connectors 100 is high. It can be understood that in addition to laser cutting, the template connector 100 can also be formed by other methods.

[0064] Specifically, the length of the second fixed edge 22 is greater than or equal to 45 mm and less than or equal to 55 mm. In a preferred embodiment of the present application, the length of the second fixed edge 22 is 50 mm, which allows sufficient space for punching and bending the fixing portion 20 during production.

[0065] The fixing portion 20 is provided with a connection hole 25 , and a fastener such as a screw can be passed through the fixing portion 20 , so as to install the fixing portion 20 on the template.

[0066] Specifically, the distance between the center of the connecting hole 25 and the third fixed edge 23 is greater than or equal to 15 mm and less than or equal to 25 mm. In a preferred embodiment of the present application, the distance between the center of the connecting hole 25 and the third fixed edge 23 is 20 mm.

[0067] The distance between the center of the connecting hole 25 and the fourth fixed edge 24 is greater than or equal to 20 mm and less than or equal to 30 mm. In a preferred embodiment of the present application, the distance between the center of the connecting hole 25 and the fourth fixed edge 24 is 25 mm.

[0068] See also Figure 3 and Figure 4 The embodiment of the present application also provides a template system 200, which includes the template connector 100 described in any of the above embodiments, and therefore has all the beneficial effects of the template connector 100. Here, the beneficial effects of the template connector 100 will not be repeated.

[0069] The template system 200 further includes an aluminum template 30 and a wooden template 40 . The fixing portion 20 is fixed to the aluminum template 30 by fasteners such as screws, and the wooden template 40 is connected to the template connector 100 .

[0070] Specifically, the number of the aluminum templates 30 is multiple, one of the fixing parts 20 of the template connector 100 is fixed to one of the aluminum templates 30, and the other fixing part 20 is fixed to another of the aluminum templates 30. And the template angle between the two aluminum templates 30 is equal to the sum of the first angle 15 and the second angle 16. The number of the template connectors 100 is multiple, and they are arranged at intervals along the length direction of the aluminum template 30, so that the connection between the two adjacent aluminum templates 30 is more secure. The wooden template 40 is cut and formed according to the spacing size between the two aluminum templates 30, and is used to fill the gap between the two aluminum templates 30. By combining the aluminum template 30 with the wooden template 40, there is no need to produce non-standard aluminum templates 30, which is convenient for reducing construction costs.

[0071] In summary, the embodiment of the present application provides a template connector 100 and a template system 200, wherein the template connector 100 is formed by stamping after laser cutting, and the production process does not require welding, and the production is simple. In the face of the different template angles between the two aluminum templates 30, the angle between the fixed portion 20 and the main body 10 can be maintained at 90°, thereby facilitating the improvement of production accuracy, and there is no need to repeatedly adjust the angle between the fixed portion 20 and the main body 10, which is convenient for improving construction efficiency. In addition, the fixed portion 20 is formed into a trapezoid, so that when producing template connectors 100 of different sizes, the angle between the first fixed edge 21 and the first edge 11, and the angle between the second fixed edge 22 and the second edge 12 can remain unchanged, and the production of the template connector 100 is simple and quick.

[0072] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
