Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction, in particular to a connecting piece, a support structure and an aluminum formwork system. BACKGROUND

[0002] Currently, there are two types of formworks in the construction field, namely aluminum alloy formwork and wooden formwork. The aluminum alloy formwork is increasingly widely used due to its reusability, good concrete forming quality and high construction efficiency. Generally, the aluminum formwork system includes an aluminum formwork, a fixed top and an aluminum formwork bracing structure. The aluminum formwork bracing structure is connected to the aluminum formwork through the fixed top.

[0003] Therefore, the current fixed top can only be connected to the existing aluminum formwork bracing structure. However, the aluminum formwork bracing structure for supporting the aluminum formwork is complex and heavy, which results in that the length of the aluminum formwork bracing structure does not exceed the standard length. If the aluminum formwork bracing structure exceeding the standard length is prefabricated in the factory, due to factors such as structure and weight, multiple workers are required to install the aluminum alloy formwork bracing structure in actual use. Since multiple bracing structures need to be installed for each building, the manufacturing and labor costs are greatly increased. The bracing structure of the wooden formwork is simple, light in weight and convenient to use. Therefore, the wooden formwork is currently used in buildings with a high layer height. However, the construction efficiency of the wooden formwork is lower than that of the aluminum formwork, and the concrete forming quality of the wooden formwork is poorer than that of the aluminum formwork.

Specifically, the preset included angle a of the first support part 11 and the second support part 211 is the included angle of the first length L1 direction and the second length L2 direction.

[0092] In some embodiments, the support piece 21 further comprises at least two limiting parts 213, the at least two limiting parts 213 are arranged on the opposite two sides of the second support part 211 and extend away from the second connecting column 212. The first support part 11 is abut

[0095] See also Figure 6 In some embodiments, there are two positioning portions 214, which are rotatably disposed on the side of the second support portion 211 away from the second connecting column 212. The first support portion 11 is disposed between the two positioning portions 214, and the two positioning portions 214 can rotate with the first support portion 11 so that the connecting portion 13 abuts against the second support portion 211. The cooperation between the positioning portions 214 and the connecting portion 13 can position the first support portion 11 and the second support portion 211, thereby improving the stability of the support structure 100.

[0096] See also Figure 7 In some embodiments, there are two positioning portions 214, each secured to the side of the second support portion 211 facing the second connecting post 212. When the predetermined angle α between the first support portion 11 and the second support portion 211 reaches a predetermined value, the two diagonally disposed connecting portions 13 respectively abut against the corresponding positioning portions 214 for positioning. It is understood that the positioning portion 214 is not limited to the side of the second support portion 211 facing the second connecting post 212; it can also be located on the side of the second support portion 211 facing away from the second connecting post 212, abutting against the first support portion 11. The number of positioning portions 214 is also not limited to two; three, four, etc., may also be provided.

[0097] See also Figure 8 The second connecting column 212 of the support member 21 is adjustably connected to the top tube 22, thereby enabling the length of the support assembly 20 to be adjusted. The top tube 22 includes an adjusting portion 221 and a tube portion 222. The adjusting portion 221 is located on the tube portion 222. The second connecting column 212 has an external thread, and the adjusting portion 221 has an internal thread. The second connecting column 212 is threadedly connected to the adjusting portion 221 and is passed through the tube portion 222. By rotating the adjusting portion 221, the relative position of the second connecting column 212 and the tube portion 222 can be adjusted to adjust the height accordingly. Optionally, the sum of the lengths of the tube portion 222 and the second connecting column 212 is greater than five meters.

[0098] In some embodiments, the structure of the support assembly 20 is similar to the conventional wooden formwork support structure, offering advantages such as light weight, a long extension length, and ease of installation. Connectors 10 connect the support assembly 20, which has the same structure as the wooden formwork support structure, to the fixed top 30, which in turn connects to the aluminum formwork 50, allowing the wooden formwork support structure 100 to support the aluminum formwork 50. This allows the aluminum formwork 50 to be used in buildings with floor heights exceeding the standard length without increasing manufacturing and labor costs.

[0099] See also Figure 9The embodiments of the present application also provide an aluminum formwork system 200, which comprises a plurality of aluminum formworks 50 and a plurality of support structures 100 in any of the above embodiments, and thus has the advantages of simple and convenient installation of the support structures 100. The plurality of support structures 100 are arranged at intervals, the aluminum formwork 50 is connected with the fixed top 30 of the support structure 100 through a pin, and the plurality of support structures 100 are connected through connecting rods.

[0100] In conclusion, the embodiments of the present application provide an aluminum formwork system 200, which is connected with the support assembly 20 of the present application through the connecting piece 10, so that the fixed top 30 is not connected with the traditional top support structure of the aluminum formwork 50. The support assembly 20 of the present application has the advantages of light weight and convenient installation, and even the support assembly 20 can be a wooden formwork top support structure. Thus, in the building with a layer height greater than the standard length, the aluminum formwork 50 can still be used without increasing the labor and manufacturing costs.

[0101] In addition, those skilled in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation on the present application, and as long as the above embodiments are within the spirit and scope of the present application, any appropriate changes and modifications of the above embodiments are within the scope of the present application.
