Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete pouring conduit fixing frame. Background Art

[0002] During the pouring construction of various bored piles, due to the deep depth of the pile foundation (generally more than 10 meters), a guide tube needs to be laid before pouring concrete. After the concrete is poured, in order to ensure the integrity of the pile foundation, the guide tube is required to have a certain burial depth in the concrete (generally 2-6 meters). During the concrete pouring process, the concrete can easily have a large impact on the pouring guide tube, causing the pouring guide tube to tilt, thereby causing the pouring machinery to become unbalanced and affecting the construction.

[0003] The utility model patent with authorization announcement number CN217977760U discloses a temporary fixing device for a concrete conduit, which specifically discloses that a first operating plate with a first avoidance groove and a second operating plate with a second avoidance groove can clamp the pipe for transporting concrete to prevent the concrete pipe from shaking left and right, thereby avoiding affecting the effect of concrete pouring. The above patent has the following problems when used: when the size of the first avoidance groove and the second avoidance groove matches the size of the pipe, although the pipe can be avoided from shaking, the first operating plate and the second operating plate are more troublesome to match, resulting in inconvenience in installation; when the size of the first avoidance groove and the second avoidance groove is larger than the pipe, although it can be easily installed, due to the large gap, the pipe is prone to shaking, which will affect the effect of concrete pouring to a certain extent.

[0032] In this embodiment, through the arrangement of two movable plates 4, two locking springs 5 and two movable blocks 6, the elastic force of the locking spring 5 can be used to adjust the size of the clamping space, which is convenient for the installation of the pouring catheter. At the same time, the elastic force of the locking spring 5 can be used to effectively fix the pouring catheter to prevent it from shaking, thereby ensuring the concrete pouring effect. Combined with the arrangement of the slide groove 7 and the slider 8, the friction resistance during the movement of the movable plate 4 can be reduced, which facilitates the adjustment of the size of the clamping space and facilitates the installation of the pouring catheter.

[0033] In the present invention, preferably, Figure 1 and Figure 4 As shown, the two movable blocks 6 are connected to the two movable plates 4 respectively.
