Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a quick-release type of embedded part construction template. Background Technology

[0002] Traditional embedded part construction templates often use welding or bolted hard connections to fix T-bolts, which requires repeated adjustments to the template position to align with the embedded points during installation, resulting in long installation times. After concrete pouring, disassembly requires violent hammering of the template, which can easily damage the bolt threads and the concrete structure. The integrated design of the template and the installation frame means that partial damage requires replacement of the entire template, resulting in significant material waste. Existing quick-release structures generally rely on threaded locking, requiring the assistance of power tools during operation. In narrow, high-humidity construction sites, these structures face risks of power supply and corrosion, and lack a protection mechanism against accidental disassembly, posing potential safety hazards during construction.

[0003] Therefore, in order to address the above problems, a quick-release and reassembly type of embedded part construction template is now being developed. Utility Model Content

[0004] To overcome the shortcomings of existing quick-release structures that generally rely on threaded locking, require power tools for operation, face power supply and corrosion risks in narrow and humid construction sites, and lack anti-misdisassembly protection mechanisms, thus posing potential safety hazards during construction, this utility model provides a quick-release embedded part construction template.

[0005] The technical implementation scheme of this utility model is as follows: a quick-release type pre-embedded part construction template, including an installation frame, three connecting rods provided on the rear side of the installation frame, a first snap-fit ​​structure provided on both the upper and lower sides of the interior of the installation frame, a rack provided on each of the first snap-fit ​​structures, the rack being used for snap-fit ​​positioning of T-bolts, an installation plate slidably connected to the front of the installation frame, a second snap-fit ​​structure provided on the rear side of the installation plate, the second snap-fit ​​structure being snap-fit ​​with the first snap-fit ​​structure.

[0006] Furthermore, both the left and right front sides of the mounting plate are rotatably connected with pull rings.

[0007] Furthermore, each of the pull rings is provided with anti-slip texture.

[0008] Furthermore, each of the connecting rods has a circular limiting piece at its rear end.

[0009] Furthermore, the mounting plate and the mounting frame are detachable connection structures.

[0010] Furthermore, a limiting block is provided on the front side of the mounting plate, and the limiting block corresponds to the position of the pull ring, which is used to limit and fix the pull ring.

[0011] By adopting the above technical solution, this utility model has the following advantages:

[0012] This utility model uses rack-and-pinion one-way self-locking technology to achieve instant locking of T-bolts by vertical pressing. At the same time, the modular mounting plate and the double-stage locking structure work together to simplify the disassembly operation to a single pull, avoiding reliance on tools and damage to concrete.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] A type of quick-release embedded part construction formwork, such as Figures 1-4 As shown, the device includes a mounting frame 1, with three connecting rods 2 on the rear side of the mounting frame 1. Each connecting rod 2 has a circular limiting piece at its rear end. The upper and lower sides of the mounting frame 1 are provided with first snap-fit ​​structures 3, each with a rack 4 for snap-fit ​​positioning of T-bolts. The front of the mounting frame 1 is slidably connected to a mounting plate 5, which is detachably connected to the mounting frame 1. The rear side of the mounting plate 5 is provided with a second snap-fit ​​structure 6, which snaps into the first snap-fit ​​structure 3. Pull rings 7 are rotatably connected to the front sides of the left and right sides of the mounting plate 5. Limiting blocks 9 are provided on the front side of the mounting plate 5, corresponding to the positions of the pull rings 7, for limiting and fixing the pull rings 7. Anti-slip textures 8 are provided on the pull rings 7.

[0020] It should be noted that the installation frame 1, as the main load-bearing structure, has three connecting rods 2 welded to its rear side that are directly inserted into the concrete pouring layer during construction. The diameter of the circular limiting piece at the end of the connecting rod 2 is larger than the rod body (≥ 1.5 times the rod diameter). Through the physical blocking effect formed after the concrete has cured, the installation frame 1 is prevented from detaching from the pouring surface. This design disperses the pull-out force to three anchoring points, significantly enhancing the tensile strength and ensuring the stability of the pre-embedded system under conditions such as concrete shrinkage and equipment vibration. The first snap-fit ​​structure 3, symmetrically arranged on the upper and lower inner sides of the installation frame 1, is made of high carbon steel and has guide grooves. The surface of the rack 4 is machined with unidirectional sawtooth patterns (tooth angle 60°±5°) and a sawtooth depth of 0.8-1. 2mm, ensuring that it can slide in smoothly when radially pressed into the T-bolt, and is firmly locked due to the tooth angle self-locking effect when pulled out in the opposite direction. During construction, the columnar shank of the T-bolt is vertically pressed into the mounting frame 1. The columnar shank generates radial pressure the instant it contacts the rack 4. At this time, the rack 4 elastically retracts outward under the preload (compression stroke ≤ 5mm), allowing the bolt column to pass smoothly. When the annular groove of the bolt head moves to the corresponding position of the rack 4, the rack 4 quickly embeds into the groove under the push of the reset force. The serrated pattern and the inner wall of the groove form a mechanical engagement. Due to the unidirectional design of the serrated pattern, when the bolt is subjected to the axial tension during equipment installation, the rack 4 will generate a wedge effect that tightens as it is pulled. The greater the tension, the tighter the engagement. The more secure the fit, the zero-gap locking is achieved. This process requires only a single press, without the need for traditional tools to tighten. The mounting plate 5 slides into contact with the front of the mounting frame 1, achieving initial positioning upon pushing in. At this point, the second locking structure 6 on the rear side of the mounting plate 5 aligns spatially with the first locking structure 3 on the mounting frame 1. Continue pushing the mounting plate 5 until the claws of the second locking structure 6 slide into the boss of the first locking structure 3. Under the action of the spring, the claws lock the side edge of the boss, forming a two-way mechanical interlock. During disassembly, the operator holds the pull rings 7 on both sides of the mounting plate 5 and rotates the pull rings 7 90°, changing them from a parallel position to a perpendicular position. Continuously pulling the pull rings 7 outwards drives the lever to push the limit block 9 along the slide groove. The displacement of the limiting block 9 is transmitted to the second locking structure 6 through the linkage rod, forcing the claw to elastically contract and disengage from the boss of the first locking structure 3. At the same time, the traction force of the pull ring 7 is amplified by the internal lever mechanism of the mounting plate 5, driving the entire mounting plate 5 to move outward along the slide rail, so that the second locking structure 6 and the first locking structure 3 are no longer in physical contact. After the mounting plate 5 is removed, the first locking structure 3 is in an unconstrained state. At this time, the operator uses a special pin puller to insert into the top screw hole of the T-bolt and apply axial tension. The tension causes the rack 4 to be squeezed in the opposite direction by the bolt groove. Because the tail end of the rack 4 is unconstrained, the rack 4 elastically retracts to the outside of the mounting frame 1 under the wedge action of the bolt groove until it is completely disengaged from the groove.
