[0002] Currently, existing similar devices (or products) have the following shortcomings:

[0003] 1. Some product designs are too flexible, resulting in poor overall stability and strength, making them inconvenient for actual production and use in projects;

[0004] 2. The current products use a variety of raw materials, which increases the difficulty of material procurement and is not conducive to convenient production, thus increasing production costs.

[0005] 3. Some products may have good overall integrity, but they have many different types of components, which increases the difficulty of installation and use, and also increases material costs and installation costs, which in turn increases the cost of turnover and loss in the later stage.

[0006] 4. Some products are only temporarily made on the construction site, which makes it difficult to control their processing quality, appearance quality and other factors, and makes it difficult to meet the green, civilized, safe and standardized construction requirements of building construction. Utility Model Content

[0007] Therefore, to address the shortcomings of the aforementioned products, standardize the use of construction platforms on building construction sites, strengthen civilized construction management, and improve the standardization and cleanliness of the project site environment, a tie rod device for formwork construction of small-volume concrete buildings is hereby constructed. The application of this utility model patent in construction has advantages such as flexible and convenient installation and use, wide application range, assemblability, reusability, high reusability, practicality, and aesthetics, resulting in significant economic and social benefits.

[0008] This utility model is implemented as follows: a tie rod device for the construction of formwork in small-volume concrete buildings is constructed, characterized in that: the device comprises a tie rod on the formwork and a flange on the formwork with connection holes;

[0009] The template tie rod consists of a tie rod crossbar and a tie rod positioning pin.

[0010] The tie rod connection hole on the flange of the template is a round hole, which is 2mm larger than the front diameter of the tie rod positioning pin and smaller than the rear diameter; this facilitates the use of the tie rod during installation on the template.

[0011] Furthermore, the tie rod crossbar is made of □50×3mm square tubing, but it can also be made of materials such as channel steel, angle steel, or steel pipe.

[0012] Furthermore, the tie rod positioning pin is designed to be made of steel pins of unequal size, or it can be made of steel pins with a certain taper at the end and equal size at the root, or it can be made of ordinary bolts.

[0013] Furthermore, the flange on the formwork with connection holes is a standard steel formwork flange, typically made of steel strip with a thickness ranging from 8-16mm, but can also be made of materials such as angle steel. The key feature is the tie rod connection hole, which is a round hole, 2mm larger in diameter than the front end of the tie rod locating pin and smaller in diameter than the rear end. This facilitates the installation and use of tie rods on the formwork.

[0014] Furthermore, the tie rod crossbar and tie rod positioning pin are fully welded together.

[0015] The advantages of this utility model are as follows: This application constructs a tie rod device for formwork construction of small-volume concrete buildings, which mainly consists of a formwork upper flange with connection holes and an upper tie rod.
