Technical Field
[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to an adjustable pre-embedded part quick fixing fixture. Background Technology
[0002] In the construction process of a factory, prefabricated components are often embedded in the concrete in advance. These prefabricated components play a crucial role, as they are needed to connect subsequent steel structures, equipment foundations, and pipe supports. In order to ensure the stability and functionality of the factory building structure, each embedded component must be precisely fixed in the correct position with the help of fixing fixtures.
[0003] However, when using fixtures to fix the position of embedded parts, there are many thorny problems: given the diverse specifications of embedded parts, the size requirements for fixtures vary; as a result, different fixtures must be made to match different specifications of embedded parts before fixing them; this not only consumes a lot of manpower, material resources and time, but also causes a serious waste of resources.
[0004] In addition, most existing fixed tooling uses a special structure and does not directly use materials that are common and readily available in the factory construction process, which undoubtedly increases the cost and manufacturing difficulty to some extent. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an adjustable quick-fixing fixture for embedded parts. This solves the problem that existing fixing fixtures are difficult to adjust according to different specifications of embedded parts, resulting in their inability to adapt well to various types of embedded parts. Furthermore, during the assembly process, the fixing fixture does not make full use of common materials available in the factory, but instead selects other non-standard materials, which increases costs.
[0006] This utility model provides an adjustable quick-fixing fixture for embedded parts, which is achieved through the following specific technical means: An adjustable quick-fixing fixture for embedded parts includes an embedded part and a limiting base. The outer surface of the embedded part holds a first fastener and a second fastener. A set of first support arms is fixedly connected to each side of the first fastener, and the bottoms of both sets of first support arms are secured to the limiting base, which is in a flat position. A first support arm is fixedly connected to one side of the second fastener. The first fastener includes a first fastening plate and a second fastening plate in a zigzag shape. The bent portion of the first fastening plate is secured to one side of the surface of the embedded part. A first screw is inserted through each end of the first fastening plate, and the threaded portion of the first screw is connected to... The first nut and the first fastening plate are connected to the second fastening plate via two first screws and the first nut.

The third fastening plate is connected to the fourth fastening plate via two sets of second screws and the second nut. The fourth fastening plate is clamped on the other side of the surface of the embedded part.
[0007] Furthermore, the limiting base includes two parallel angle irons, which are welded together by a welding plate, and bamboo plywood is laid at the bottom of both ends of the angle irons.
[0008] Furthermore, the first support arm includes a first long plate and a section of channel steel. A rectangular first connecting plate is vertically welded on the top of the channel steel. The first connecting plate has reinforcing ribs on both sides. The upper end of the first connecting plate is fixedly connected to the lower end of the first long plate by bolt pairs. The first long plates of the two sets of first support arms are fixedly connected to the first fastening plate and the second fastening plate at the other end by bolt pairs, respectively.
[0009] Furthermore, the angle iron has equidistant limiting notches of the same specification cut on both sides, and the channel steel of the two sets of first support arms is symmetrically overturned on the parts where limiting notches are opened on both sides of the angle iron.
[0010] Furthermore, a sleeve is fitted onto the first screw, with both ends of the sleeve contacting the first fastening plate and the second fastening plate, respectively.
[0011] Furthermore, a second connecting plate is welded to one side of the third fastening plate; the second support arm includes a second long plate and a section of angle steel, one end of the second long plate is fixedly connected to the second connecting plate by a bolt pair, and the other end is fixedly connected to the angle steel by a bolt pair, with a ground cone vertically inserted through the angle steel.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes angle iron with multiple sets of equidistant limiting notches at both ends. The bottom of the first support arm can selectively engage with these limiting notches, thereby enabling flexible adjustment of the support height of the first support arm. This adjustment function allows for precise clamping and fixing of the upper end of the embedded part, significantly improving the fixing effect. Furthermore, the materials used in this fixing fixture are readily available during factory construction, making full use of existing resources and reducing manufacturing costs. In addition, this fixing fixture is easy to disassemble after use and has good reusability, demonstrating significant advantages in practical applications. Attached Figure Description

A first fastening plate 41 is connected to a second fastening plate 44 via two first screws 42 and the first nut 43. The second fastening plate 44 is clamped on the other side of the surface of the embedded part 10. The second fastener 50 includes a third fastening plate 51 and a fourth fastening plate 54. Both the third fastening plate 51 and the fourth fastening plate 54 are provided with arc surfaces. The arc surface of the third fastening plate 51 is clamped on one side of the surface of the embedded part 10. A second screw 52 is inserted through each end of the third fastening plate 51. The threaded part of the second screw 52 is connected to a second nut 53. The third fastening plate 51 is connected to the fourth fastening plate 54 via two sets of second screws 52 and second nuts 53. The fourth fastening plate 54 is clamped on the other side of the surface of the embedded part 10.
[0023] Among them, such as Figure 3 As shown, the limiting base 20 includes two parallel angle irons 21, which are welded together by a welding plate 22. Bamboo plywood 23 is laid at the bottom of both ends of the angle irons 21. By laying bamboo plywood 23, the bamboo plywood 23 is placed between the ground and the angle irons 21, avoiding large-area uneven pressure marks caused by the angle irons 21 on the uncured ground, thus facilitating other subsequent work after the removal of the fixing fixtures.
[0024] Among them, such as Figure 4 As shown, the first support arm 30 includes a first long plate 34 and a section of channel steel 31. A rectangular first connecting plate 32 is vertically welded above the channel steel 31. Reinforcing ribs 33 are provided on both sides of the first connecting plate 32. The upper end of the first connecting plate 32 is fixedly connected to the lower end of the first long plate 34 via bolts. Figure 1As shown, the first long plates 34 of the two sets of first support arms 30 are respectively fixedly connected to the first fastening plate 41 and the second fastening plate 44 at their other ends by bolt pairs; as Figure 3 As shown, the angle iron 21 has equidistant limiting notches 211 of the same specification cut on both sides, as...

[0025] Among them, such as Figure 5 As shown, a sleeve 45 is fitted onto the first screw 42. The two ends of the sleeve 45 are in contact with the first fastening plate 41 and the second fastening plate 44, respectively. By clamping the embedded part 10 between the bent parts of the first fastening plate 41 and the second fastening plate 44, and by fastening the first fastening plate 41 and the second fastening plate 44 with two sets of first screws 42 and first nuts 43, the upper end of the embedded part 10 is clamped and fixed. The sleeve 45 limits the first fastening plate 41 and the second fastening plate 44 to prevent the first fastening plate 41 and the second fastening plate 44 from bending and deforming when the first nut 43 is tightened.
[0026] Among them, such as Figure 6 As shown, a second connecting plate 55 is welded to one side of the third fastening plate 51; as Figure 7 As shown, the second support arm 60 includes a second long plate 63 and a section of angle steel 61. One end of the second long plate 63 is fixedly connected to the second connecting plate 55 by a bolt pair, and the other end is fixedly connected to the angle steel 61 by a bolt pair. A ground cone 62 is vertically inserted through the angle steel 61. The second support arm 60 supports the embedded part 10 in a support direction perpendicular to the first support arm 30. The ground cone 62 can effectively limit the bottom of the second support arm 60, thereby providing more stable support for the embedded part 10.
[0027] The specific usage and function of this embodiment are as follows: In this invention, two bamboo plywood boards 23 are laid on the ground, and two angle irons 21 along with a welding plate 22 are placed on the bamboo plywood boards 23, with the two bamboo plywood boards 23 close to the two ends of the angle irons 21 respectively. An embedded part 10 is vertically embedded in the ground between the two angle irons 21. The first long plates 34 of the two sets of first support arms 30 support the first fastening plate 41 and the second fastening plate 44 respectively. The channel steels 31 at the bottom of the two sets of first support arms 30 are symmetrically engaged in the limiting notches 211 opened on both sides of the angle irons 21. The engagement position is determined according to the length of the embedded part 10, so that the first fastening plate 41 and the second fastening plate 44 can be as close as possible to the uppermost end of the embedded part 10. The embedded part 10 is then secured to the first fastening plate... Between the bent portions of the first and second fastening plates 41 and 44, the first and second fastening plates 41 and 44 are fastened by two sets of first screws 42 and first nuts 43 to clamp and fix the upper end of the embedded part 10, preventing the embedded part 10 from tilting to both sides; the third and fourth fastening plates 51 and 54 are clamped on both sides of the embedded part 10 and fastened by two sets of second screws 52 and second nuts 53; one side of the second long plate 63 of the second support arm 60 is placed on the ground; the lower end of the ground cone 62 is inserted vertically into the ground through the second long plate 63; and the embedded part 10 is supported by the second support arm 60 in a support direction perpendicular to the first support arm 30.
