Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a fixing structure for I-beams. Background Art

[0002] The end of the cantilever I-beam is the main stress-bearing part. In existing construction, wooden wedges are generally driven into the gap between the web of the I-beam and the U-shaped embedded screw. During the construction process, due to various reasons, the wooden wedges fall off or shift, resulting in the ineffective fixation of the cantilever I-beam in the horizontal direction. For example, in Chinese Patent CN114575573A, a fixing structure for a cantilever I-beam, its horizontal fixation is achieved by filling hard wooden wedges between the pressing plate and the cast-in-place floor slab. The hard wooden wedges are only restricted in the vertical direction and have little restriction in the horizontal direction, making it easy to shift in the horizontal direction. Summary of the Invention

[0003] The technical problem to be solved by the utility model: Aiming at the problem that the cantilever I-beam cannot be effectively fixed in the horizontal direction during installation, a fixing structure with horizontal support is provided.

[0004] The technical solution of the present invention:

[0005] An end fixing device for a cantilever I-beam includes an embedded part 8. The exposed part of the embedded part 8 is four vertical rods. The I-beam 1 is placed between the four vertical rods. On both sides of the I-beam 1, a base plate 4 is provided. Two groups of sleeves 7 are fixed on the back of the base plate 4. The sleeves 7 are sleeved on the vertical rods of the embedded part 8. A pressing plate 2 is arranged on the top of the I-beam 1. The upper end of the vertical rod has a thread and passes through the pressing plate 2, and the pressing plate 2 is fixed with a fastening nut 3.

[0006] A screw rod 6 is vertically installed on the base plate 4, and the adjusting screw rod 6 abuts against the web of the I-beam 1.

[0007] Two holes are opened on the base plate 4 and nuts 5 are installed on the holes. The two nuts 5 are horizontally arranged, and the screw rod 6 is matched with the nuts 5.

[0008] The embedded part 8 is two U-shaped screws.

[0009] The embedded part 8 further includes two reinforcing bars 9, and the two reinforcing bars are located inside the bending parts of the U-shaped screws.

[0010] Compared with the prior art, the advantages of the present invention are as follows:

[0011] Base plates are provided on both sides of the I-beam as a fixing structure, which does not displace or fall off during the construction process, ensuring the effective fixation of the cantilever I-beam in the horizontal direction, and can be reused and is easy to install.

[0016] Example 1:

[0017] First, install the embedded part 8. The embedded part 8 is two U-shaped screw rods. The bent part of the U-shape is embedded, and the exposed part is four vertical rods. Place the I-beam 1 between the four vertical rods. On both sides of the I-beam 1, set a steel base plate 4 each. Two groups of sleeves 7 are fixed on the back of the base plate 4. The sleeves 7 are sleeved on the vertical rods of the embedded part 8. Set a pressing plate 2 on the top of the I-beam 1. The upper end of the vertical rod has threads and passes through the pressing plate 2, and use the fastening nut 3 to fix the pressing plate 2. Then insert a hardwood wedge between the web of the I-beam 1 and the base plate 4 to complete the fixation in the horizontal direction.

[0018] The embedded part 8 also includes two reinforcing bars 9, and the two reinforcing bars are located inside the bent part of the U-shaped screw rod.

[0019] Example 2:

[0020] Two U-shaped embedded bolts 8 are embedded in the main structure and are reinforced with reinforcing bars 9.

[0021] The diameter of the sleeve 7 is taken as 22 mm. The sleeve is welded on the steel base plate 4, the nut 5 is welded on the steel base plate 4, and holes are opened at the corresponding positions of the steel base plate 4. The screw rod 6 passes through the steel base plate 4 and is screwed into the nut 5.

[0022] When installing the cantilever I-beam 1, the sleeve 7 is sleeved on the U-shaped embedded bolt 8, and the top of the cantilever I-beam 1 is pressed tightly with a steel pressing plate 2. The steel pressing plate 2 and the U-shaped embedded bolt 8 are fastened with a fastening nut 3.

[0023] After the steel pressing plate 2 is installed, adjust the position of the sleeve 7 up and down so that the screw rod 6 is roughly located in the middle of the cantilever I-beam 1. Then use a tool to tighten the screw rod 6 so that the two screw rods 6 press against the web of the cantilever I-beam 1 to fix the cantilever I-beam 1.
