Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a positioning device for a beam-piercing sleeve. Background Art

[0002] With the increasing height of buildings, the use of climbing scaffolds is becoming more and more extensive, and the number of embedded bolts for climbing scaffold fixing points is increasing. At the same time, the number of wall attachments for external tower cranes and construction elevators in buildings is also increasing. These devices are connected and fixed to the building through embedded bolts on the side of the beam, and the accuracy requirements are also getting higher and higher. Secondary hole opening will increase costs, and even dense holes will affect the structural stress and cannot meet the use requirements.

[0003] The conventional method is to directly fix the bolts on the steel bars or templates, or install matching nuts inside the beam, and then screw the bolts in after the structure is poured. However, due to the small contact area with the template and the inability to effectively tie the rear part to the steel bars, it is difficult to fix the bolts or nuts inside the beam, and problems such as deviation, inclination, and sinking into the structure are likely to occur during the pouring process, affecting the installation. Summary of the Utility Model

[0006] The positioning device for a beam-piercing sleeve includes an inner template and a fixed pipe. The lower end of the front surface of the inner template is fixedly connected with a support plate, and the front surface of the support plate is fixedly connected with an outer template. A support structure is arranged in the middle of the front surface of the inner template, an outer mold hole is opened in the middle of the front surface of the outer template, a beam-piercing sleeve is inserted into the inner part of the outer mold hole, a plug head adapted to the beam-piercing sleeve is fixedly connected to the back surface of the fixed pipe, a lock is fixedly connected to the front surface of the outer template, and lock blocks adapted to the lock are fixedly connected to both sides of the surface of the plug head.

[0007] As a further improvement of the utility model, the support structure includes a threaded hole opened in the middle of the front surface of the inner template, and a connecting bolt is threadedly connected inside the threaded hole.

[0008] As a further improvement of the utility model, one end of the connecting bolt is fixedly connected with a cylindrical convex block adapted to the beam-piercing sleeve.

[0009] As a further improvement of the utility model, a nut is fixedly connected to the front surface of the cylindrical convex block.

[0010] As a further improvement of the utility model, a handle is fixedly connected to the surface of the fixed pipe.

[0011] As a further improvement of the present utility model, an anti-corrosion coating is provided inside the beam-piercing sleeve, and the material of the anti-corrosion coating is polyethylene.

[0012] Advantages of the present utility model:

[0013] By providing a support structure, during use, when processing the aluminum formwork, a cylindrical protrusion block is added at the corresponding position of the inner formwork, and an outer formwork hole is opened on the outer formwork, the size of which is determined according to the diameter of the embedded bolt. The cylindrical protrusion block is installed into the threaded hole of the inner formwork through a connecting bolt. After the side beam steel bars are installed, the supporting beam-piercing sleeve is inserted through the outer formwork hole and sleeved on the cylindrical protrusion block of the inner formwork, so that the device can be disassembled after the concrete pouring is completed, and the formwork can be removed and recycled, increasing the practicality of the device.

[0014] By providing a plug, during use, after the beam-piercing sleeve is installed, the plug is inserted into the beam-piercing sleeve. After complete insertion, the fixing pipe is rotated to snap the locking block into the lock, so that the device can firmly fix both ends of the beam-piercing sleeve in the beam, and is not afraid of the impact of concrete and vibrating rods, avoiding problems such as deviation, inclination, and sinking into the structure, and increasing the stability of the device.
