[0021] In order to further describe the present utility model, the following provides a more detailed description of a fixed connection member for a steel structure in a civil engineering project of the present utility model with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , a fixed connection member for a steel structure in a civil engineering project of the present utility model includes vertical and horizontal I-shaped steels 1 that need to be perpendicularly connected to each other, and the vertical and horizontal I-shaped steels 1 are fixedly installed through a connector 2.

[0023] Please refer to Figures 2 - 6 , the connector 2 includes two upper and lower L-shaped sleeve plates 21 that are symmetrically arranged back to back. In addition, the upper and lower sleeve plates 21 are based on the two sleeve plates 21, so every two sleeve plates 21 form a group to form the upper and lower sleeve plates 21.

[0024] The top end of the sleeve plate 21 is slidably sleeved on the vertical I-shaped steel 1 and is fixedly installed through a first connection bolt 25. A groove 22 is formed on the surface of the sleeve plate 21, and a sliding plate 23 is slidably sleeved in the inner cavity of the groove 22. The side end of the sleeve plate 21 is slidably sleeved on the horizontal I-shaped steel 1. The end of the first connection bolt 25 is located on the surface of the inner cavity of the groove 22 and is flush with the surface of the inner cavity of the groove 22. The first connection bolt 25 is inserted and fixed from the surface of the inner cavity of the groove 22. Since a counterbore is formed on the surface of the inner cavity of the groove 22 and the end of the first connection bolt 25 is exactly located in the counterbore, this will not affect the movement of the sliding plate 23 in the groove 22.

[0025] The skateboard 23 is in mutual contact with the surface of the transverse I-beam 1, and the skateboard 23, the transverse I-beam 1 and the sleeve plate 21 are fixedly installed through the first connecting bolt 25. The surface of the skateboard 23 is flush with the surface of the sleeve plate 21. The sleeve plate 21 and the skateboard 23 are slidably sleeved through the connecting rod 28. Installation grooves 27 are formed in the upper and lower opposite surfaces of the sleeve plate 21, and a connecting plate 24 is slidably sleeved in the inner cavity of the installation groove 27. The first connecting bolt 25 provided therein can cause the sleeve plate 21 and the skateboard 23 to open left and right respectively, so as to change the width of the sleeve plate 21. In addition, moving the skateboard 23 can change the thickness of the side ends of the skateboard 23 and the sleeve plate 21, and the upper and lower sleeve plates 21 can be connected through the connecting plate 24, and the distance therebetween can be changed. The ends of the connecting rod 28 and the connecting plate 24 have limiting heads in the inner cavities of the sleeve plate 21 and the skateboard 23, and sliding grooves for the limiting heads to slide are formed in the inner cavities of the sleeve plate 21 and the skateboard 23, so that the connecting rod 28 and the connecting plate 24 will not fall off from the sleeve plate 21 and the skateboard 23, as Figure 5 , Figure 6 shown.

[0026] During use, first, according to the size of the vertical I-beam 1, the sleeve plate 21 and the skateboard 23 are unfolded through the connecting rod 28, so as to adjust the sleeve plate 21 to be slidably sleeved on the vertical I-beam 1. After determining the position, first pass through the sleeve plate 21 and the vertical I-beam 1 from the surface of the inner cavity of the groove 22 and perform fixed connection. Then, the lower sleeve plate 21 is adjusted by sliding the connecting plate 24, so that the side ends of the upper and lower sleeve plates 21 can just be inserted into the transverse I-beam 1. After determining the position, the lower sleeve plate 21 is also fixed through the first connecting bolt 25. Then, one end of the transverse I-beam 1 is inserted into the side ends of the upper and lower sleeve plates 21. At the same time, due to the thickness of the transverse I-beam 1, the skateboard 23 will be squeezed, so that the skateboard 23 slides in the groove 22, and the skateboard 23 is automatically adjusted according to the thickness of the transverse I-beam 1. Then, the second connecting bolt 26 passes through the skateboard 23, the transverse I-beam 1 and the side end of the sleeve plate 21 for fixed installation, so as to complete the fixed connection of the I-beam 1, and the adjustment is carried out through the sleeve plate 21 and the skateboard 23, so as to complete the fixed connection of the I-beam 1 with different sizes.
