Description

Technical Field

[0001] This utility model relates to the field of PC prefabrication technology, specifically a U-shaped slot through-beam sleeve fixing mold. Background Technology

[0002] Many pipes need to pass through beams inside building structures. Therefore, it's necessary to pre-embed sleeves within the main beams during the main structural construction to avoid openings in the main structure later, which could compromise structural safety. This method is mainly used in the pre-embedding stage of building construction and the prefabrication stage of PC vertical components. There are three main methods for pre-embedding sleeves: 1. Weld an angle steel lug to each end of the sleeve and fix the angle steel to the formwork with rivets for sleeve positioning and installation; 2. Use a plastic sleeve, weld a ring and an angle steel lug to each end, insert the plastic sleeve through them, and then fix the angle steel to the top of the formwork with rivets for sleeve positioning and installation; 3. Directly fix the metal sleeve to the internal reinforcing steel bars of the main beam by welding or wire binding.

[0003] For example, a U-shaped slot through-beam sleeve fixing mold with patent document number CN215928650U includes multiple opposing templates. A card plate is fixed on the template, and a U-shaped slot is opened on the card plate. A sleeve is placed on two of the U-shaped slots. This utility model improves construction efficiency and sleeve positioning accuracy, eliminates the use of welding materials such as steel bars and angle steel. The mold of this utility model can be reused and installed and fixed on the inner side mold of the main beam in one go without removal. The sleeve is placed directly on the slot of the mold, eliminating the need for workers to repeatedly position the dimensions and saving the welding and anchoring processes of traditional processes.

[0004] However, this mechanism has the following problems: First, the screws need to be re-tapping each time the card is installed. If the position of the card is wrong or there is a deviation, the screws need to be removed and the threaded holes re-tapping is required, which can easily lead to stripping of the threads. Second, the adjustment of the spring is not easy to operate, which increases the difficulty of debugging. Utility Model Content

[0005] The purpose of this utility model is to provide a U-shaped slot through-beam sleeve fixing mold to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped slot through-beam sleeve fixing mold, comprising a template 3 installed opposite to each other, a clamping plate 10 provided on the template 3, characterized in that: the template 3 is provided with evenly distributed and continuous T-shaped grooves 2, T-shaped nuts are provided in the T-shaped grooves 2, and long grooves 1 are provided on both sides of the clamping plate 10, bolts pass through the long grooves 1 and lock with the T-shaped nuts in the T-shaped grooves 2, thereby adjusting and fixing the position of the clamping plate 10 on the template 3.

[0007] Furthermore, the card plate 10 is provided with an adjustment plate 4 on both sides and a central adjustment block 10 in the middle. The adjustment plate 4 and the central adjustment block 9 are respectively provided with a long groove 3 17 and a long groove 2 8, and are fixed to the locking threads 12 on the mounting surface 13 and the mounting groove 14 by bolts.

[0008] Furthermore, the top of the adjustment plate 4 is provided with an arc-shaped protrusion 18, and the top of the central adjustment block 9 is provided with a movable arc surface 5 with the same diameter as the arc surface 7 of the card plate.

[0009] Furthermore, the lower plane of the mounting surface 13 is provided with a continuous wedge-shaped groove 11, and the lower part of the adjusting plate 4 is provided with a wedge-shaped block 16 that cooperates with the wedge-shaped groove 11.

[0010] Furthermore, the card plate 10 is provided with a guide groove 15 in the middle, which cooperates with the side guide blocks 6 on both sides of the central adjustment block 9.

[0011] The present invention has the following advantages: First, the template is provided with a prefabricated T-shaped long groove, which can be used in conjunction with a T-shaped nut. The card plate is provided with a long groove, which can be adjusted at any time, avoiding the need to re-drill holes due to incorrect positioning. Second, the pipe diameter can be adjusted by using an adjusting block, which is more convenient and efficient. Attached Figure Description
