How to choose bridge steel formwork and the standard of matching plate

What should I pay attention to when selecting bridge steel templates? What standards do we have when we use bridge steel formwork for board distribution? I believe many people are not very familiar with these two issues. Hubei Wangke Template Co., Ltd. will take you to know about it

First, how to choose bridge steel template

(1) The steel formwork of the bridge should ensure that the shape, size and mutual position of the components are correct.

(2) The formwork must have sufficient strength, rigidity and stability to bear the weight of the fresh concrete And lateral pressure, and various construction loads.

(3) The bridge steel formwork strives to be simple in structure, easy to assemble and disassemble, does not hinder the binding of steel bars, and ensures that the concrete is poured No leakage.

(4) For the prepared template, the general and large template should be selected first, so that the type and number of blocks are small , The amount of wood mold inlay is small. Set the template of the tension bolt, in order to reduce the drilling loss of the steel template, 55mmx100mm planed square timber can be used instead of the bolt part.

(5) The longitudinal splicing of the template should be staggered to increase the overall rigidity of the template.

(6) The support system of the template should be arranged according to the load of the template and the stiffness of the components.

(7) The layout design of the template should be drawn with a layout diagram, indicating the location, specification and model of the steel template And quantity. The pre-assembled large template shall be marked with its dividing line. The positions of the embedded body and reserved holes shall be marked on the board plan, and the fixing method shall be indicated.

Second, how should the bridge steel template be equipped with boards

1. The bridge steel formwork should be equipped with satisfactory strength, rigidity and stability. Ensure that the steel formwork can accept the weight of concrete and the bearing capacity of all construction.

2. Before arranging the steel template, the corresponding layout should be planned, and the number of steel templates and The position is accurately marked.

3. When the bridge steel formwork is equipped with a board, try to choose a board with a larger area as much as possible. Ensure that the strip steel template belongs to the universal type. The bolts for fixing the steel formwork should use the opposite bolts to reduce the wear when the steel formwork is drilled.

4. When the bridge steel template is matched with the board, it should ensure the shape of the construction and the rationality and correctness of the specification .

5. When the bridge steel formwork is matched with the board, the structure should be as simple as possible and the transfer should be convenient; it should also be ensured There is no leakage when the steel formwork is used for pouring

6, steel template matching board, if you choose a long way mosaic, you should try to stagger the placement, this This method is conducive to advancing the stiffness effect of the entire steel formwork.

The above is a brief analysis of how to choose bridge steel template and the relevant knowledge of the board standard. I hope Can help everyone!
