Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall embedded part installation and reinforcement technology, and in particular to a simple fixing device for curtain wall embedded parts. Background Technology
[0002] In the field of building engineering, curtain wall systems are widely used on the facades of various buildings due to their aesthetics and functionality. Curtain wall installation requires the pre-embedding of embedded parts in the concrete structure, and the positioning accuracy directly affects the overall installation quality and safety of the curtain wall.
[0003] Currently, many building projects use curtain wall systems for their facades. Curtain wall systems require the installation of embedded curtain wall components in advance, which need to be placed in reinforced concrete. During installation, traditional methods use wire ties, nails, or spot welding to fix the reinforcing bars.
[0004] However, during the concrete vibration process, the embedded parts are easily displaced by the impact of external forces. The embedded parts of the curtain wall may not be firmly reinforced due to the vibration, or may even fall off, affecting the accuracy of the embedded parts installed in the curtain wall, affecting the subsequent installation of the curtain wall glass, and also having a certain impact on the construction period.
[0005] Based on this, a simple fixing device for curtain wall embedded parts is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a simple fixing device for curtain wall embedded parts to solve the problems mentioned in the background art.
[0007] The technical solution of this utility model is: a simple fixing device for embedded parts in curtain walls, including a template, and further comprising:
[0008] The T-shaped curtain wall embedded body is fixed inside the template;
[0009] The tie rods fix the T-shaped curtain wall embedded body and the template. The T-shaped curtain wall embedded body and the template have a through hole on one side. The tie rods are placed inside the through hole. The surface of the tie rods is provided with two butterfly buckles and two nuts.
[0010] In some embodiments, the T-shaped curtain wall embedded body and the template are fixedly connected to the same sleeve on opposite sides, and the tie rod is disposed inside the sleeve.
[0011] In some embodiments, the two butterfly buckles and the two nuts are symmetrically sleeved on the surface of the tie rod and respectively abut against both sides of the template to lock the T-shaped embedded body and the template in both directions.
[0012] In some embodiments, the template is internally reinforced with steel bars.
[0013] In some embodiments, the tie rod is inserted into the sleeve for positioning and guidance, and the butterfly buckle and nut are respectively sleeved on both ends of the tie rod, and the nuts on both sides are tightened simultaneously until the embedded part and the template are rigidly fixed in both directions.
[0014] Compared with existing technologies, the significant advantages of this invention are:
[0015] Firstly, this utility model uses a two-way synchronous locking mechanism, combining tie rods with double-sided butterfly buckles and nuts to form symmetrical pressure on both sides of the template, making the T-shaped embedded part rigidly fit with the template. Compared with the traditional single-point fixing with wire, this structure dynamically resists impact force during concrete vibration, ensuring the accuracy of the curtain wall installation base.
[0016] Secondly, this utility model enables the rapid assembly of T-shaped curtain wall embedded parts by positioning the T-shaped curtain wall embedded part body, inserting the threaded rod, and then simultaneously tightening the nut. After the concrete has initially set, the nut can be loosened to remove the tie rod and butterfly buckle for reuse. The sleeve design further avoids the threaded rod being wrapped in concrete and is damaged, thus reducing construction costs. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0024] This utility model provides an improved, simple fixing device for curtain wall embedded parts. The technical solution of this utility model is as follows:
[0025] like Figures 1-3 As shown, a simple fixing device for embedded parts in a curtain wall includes a template 1, and also includes:
[0026] T-shaped curtain wall embedded body 3, the T-shaped embedded body is fixed inside the template 1;
[0027] The tie rod 5 fixes the T-shaped curtain wall embedded body 3 and the template 1. The T-shaped curtain wall embedded body 3 and the template 1 have a through hole on one side. The tie rod 5 is set inside the through hole. The surface of the tie rod 5 is provided with two butterfly buckles 6 and two nuts 7. The two butterfly buckles 6 and two nuts 7 are symmetrically sleeved on the surface of the tie rod 5 and respectively abut against both sides of the template 1 to lock the T-shaped embedded body and the template 1 in both directions.
[0028] like Figure 2 As shown, in one embodiment, the T-shaped curtain wall embedded body 3 and the template 1 are fixedly connected to the same sleeve 4 on opposite sides. The tie rod 5 is set inside the sleeve 4. The sleeve 4 is made of PVC or galvanized steel pipe and is pre-welded to the surface of the vertical anchoring section of the embedded body. One end of the sleeve 4 is vertically welded to the through hole position of the embedded body. When positioning the embedded part, the free end of the sleeve 4 is pressed against the inner surface of the template 1 to form an axial limit. The tie rod 5 is inserted into the sleeve 4 to eliminate the radial shaking of the screw caused by vibration.
[0029] The interior of template 1 is equipped with reinforcing bars 2.
[0030] The tie rod 5 is inserted into the sleeve 4 for positioning and guidance. The butterfly buckle 6 and nut 7 are respectively sleeved on both ends of the tie rod 5, and the nuts 7 on both sides are tightened simultaneously until the embedded part and the template 1 are rigidly fixed in both directions.
[0031] The specific working method is as follows: When using it, after binding the steel bars 2 in the template 1, place the T-shaped curtain wall embedded body 3 in the preset position inside the template 1, and then fix and install the sleeve 4 on the contact surface between the template 1 and the T-shaped embedded body 3; the free end is pressed against the inner wall of the template 1, and the tie rod 5 is inserted from the outside of the template 1, passing through the through hole of the template 1, the inner cavity of the sleeve 4, the T-shaped curtain wall embedded body 3, the through hole, and the inner side of the template 1 in sequence;
[0032] First, insert the butterfly buckle 6 into the screw end inside the template 1, then screw in the nut 7. Use a torque wrench to tighten the nuts 7 on both sides simultaneously. During the tightening process, keep the feed amount of the nuts 7 on both sides consistent until there is no visible gap between the embedded part body and the template 1.
[0033] During the vibration operation, a designated person monitors the locking status of nut 7. If any loosening is found, it is tightened immediately. After the concrete has initially set, the tie rod 5 and the locking components are removed to form a precisely embedded curtain wall connection node.
[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
