Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a temporary fixing device for pre-embedded bolts. Background Technology

[0002] Pre-embedded bolts are a crucial connection technology in civil and building engineering. Their function is to serve as pre-set connection points for installing and securing other structural components, equipment, railings, curtain walls, pipe supports, etc., after concrete has hardened. Before concrete pouring, pre-embedded bolts need to be positioned and temporarily fixed to the formwork or reinforcing steel frame (or anchor bolts). After the concrete is poured, the pre-embedded bolts are permanently fixed. Current methods for temporarily fixing pre-embedded bolts typically involve tying them to the foundation's reinforcing steel. However, this method is prone to displacement and tilting, leading to inaccurate positioning and misalignment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a temporary fixing device for pre-embedded bolts that is easy to operate and accurately positioned.

[0004] To solve the above-mentioned technical problems, this utility model provides a temporary fixing device for pre-embedded bolts, including a fixing plate, an adjusting stud, a first adjusting nut, and a second adjusting nut. The top of the fixing plate is provided with multiple fixing through holes that match the pre-embedded bolts and multiple fixing nuts for threaded connection with the pre-embedded bolts. The fixing nuts correspond one-to-one with the fixing through holes and are coaxially arranged. Positioning blocks are provided on opposite sides of the fixing plate. Each positioning block has a positioning through hole, and the adjusting stud passes through the positioning through hole. The first adjusting nut and the second adjusting nut are threadedly connected to the adjusting stud. The first adjusting nut is located above the positioning block, and the second adjusting nut is located below the positioning block. The first adjusting nut and the second adjusting nut cooperate to clamp the positioning block.

[0005] As a preferred embodiment of this utility model, the device further includes a mounting cylinder, and the bottom end of the adjusting stud can be adjusted vertically and inserted into the mounting cylinder.

[0006] As a preferred embodiment of this utility model, the bottom of the mounting cylinder is fixed with a mounting base, and the mounting base is provided with mounting holes.

[0007] In a preferred embodiment of this utility model, the adjusting stud is matched with the mounting cylinder.

[0008] As a preferred embodiment of this utility model, a limiting nut is threadedly connected to the adjusting stud, and the limiting nut is mounted on the top of the mounting cylinder.

[0009] As a preferred embodiment of this utility model, the positioning through hole is matched with the adjusting stud.

[0010] As a preferred embodiment of this utility model, the positioning blocks are respectively provided on the four sides of the fixing plate.

[0011] As a preferred embodiment of this utility model, the fixing plate is a steel plate.

[0012] This utility model provides a temporary fixing device for pre-embedded bolts. Compared with the prior art, its advantages are as follows: In use, the adjusting stud is first installed and fixed on the concrete pad, and then the pre-embedded bolt is threadedly connected to the fixing nut and passed through the fixing hole. Since the pre-embedded bolt matches the fixing through hole, and the fixing nut is located on the fixing plate, the temporary fixing of the pre-embedded bolt can be achieved, and the operation is simple. At this time, the length of the pre-embedded bolt extending out of the fixing nut can be adjusted by rotating the pre-embedded bolt. By rotating the first adjusting nut and the second adjusting nut, the overall height of the fixing plate can be adjusted, thereby adjusting the height of the pre-embedded bolt to ensure that the pre-embedded bolt reaches the pre-embedded elevation, thereby achieving accurate positioning of the pre-embedded bolt.

Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1-3 As shown, a preferred embodiment of the present invention provides a temporary fixing device for pre-embedded bolts, including a fixing plate 1, an adjusting stud 2, a first adjusting nut 3, and a second adjusting nut 4. The top of the fixing plate 1 is provided with multiple fixing through holes 11 that match the pre-embedded bolts 8, and multiple fixing nuts for threaded connection with the pre-embedded bolts 8. Generally, the fixing through holes 11 are arranged vertically, and the fixing nuts can be separated from the fixing plate 1. If the fixing nuts are placed on the fixing plate 1, the diameter of the pre-embedded bolts 8 is suitable for the diameter of the fixing through holes 11, allowing the pre-embedded bolts 8 to pass through the fixing through holes 11 without significant horizontal displacement. (Offset within tolerance range) The fixing nut and the fixing through hole 11 correspond one-to-one and are coaxially arranged. The fixing plate 1 has positioning blocks 5 on opposite sides. The positioning block 5 has a positioning through hole 51. An adjusting stud 2 passes through the positioning through hole 51. Generally, the positioning through hole 51 is arranged vertically, while the adjusting stud 2 can be adjusted vertically. The adjusting stud 2 is threaded with a first adjusting nut 3 and a second adjusting nut 4. The first adjusting nut 3 is located above the positioning block 5, and the second adjusting nut 4 is located below the positioning block 5. The first adjusting nut 3 and the second adjusting nut 4 cooperate to clamp the positioning block 5.

[0020] The working principle of this embodiment is as follows: In use, the adjusting stud 2 is first installed and fixed on the concrete pad, and then the pre-embedded bolt 8 is threadedly connected to the fixing nut and passed through the fixing hole. Since the pre-embedded bolt 8 matches the fixing through hole 11, and the fixing nut is located on the fixing plate 1, the pre-embedded bolt 8 can be temporarily fixed. At this time, the length of the pre-embedded bolt 8 extending out of the fixing nut can be adjusted by rotating the pre-embedded bolt 8. By rotating the first adjusting nut 3 and the second adjusting nut 4, the overall height of the fixing plate 1 can be adjusted, thereby adjusting the height of the pre-embedded bolt 8 to ensure that the pre-embedded bolt 8 reaches the pre-embedded elevation. Since the fixing plate 1 has positioning blocks 5 on opposite sides, it helps the fixing plate 1 to remain horizontal and helps to accurately position the pre-embedded bolt 8. When disassembling, first rotate the fixing nut to separate the fixing nut from the pre-embedded bolt 8, and then disassemble the adjusting stud 2 from the concrete pad, so that the entire device can be removed.

[0021] For example, the device also includes a mounting cylinder 6, which is arranged vertically. The bottom end of the adjusting stud 2 can be adjusted vertically and inserted into the mounting cylinder 6. In use, the mounting cylinder 6 is installed and fixed on the concrete pad. The adjusting stud 2 can be adjusted vertically relative to the mounting cylinder 6, thereby adjusting the overall height of the fixing plate 1, which helps to increase the adjustable range of the height of the embedded bolt 8.

[0022] For example, the bottom of the mounting cylinder 6 is fixed with a mounting base 7. The mounting cylinder 6 and the mounting base 7 are welded and fixed. The mounting base 7 serves as a supporting base. The mounting base 7 is provided with a mounting hole 71. The mounting hole 71 can be used to install and fix the mounting base 7 on the concrete pad layer through the expansion bolt, which facilitates the installation and fixing of the mounting base 7.

[0023] For example, the adjusting stud 2 is matched with the mounting cylinder 6 to prevent the adjusting bolt from undergoing a large horizontal displacement within the mounting cylinder 6, thus ensuring positioning accuracy.

[0024] For example, a limiting nut 21 is threaded onto the adjusting stud 2. The limiting nut 21 is mounted on the top of the mounting cylinder 6. The limiting nut 21 prevents the adjusting bolt from accidentally moving down relative to the limiting cylinder. Rotating the limiting nut 21 can adjust its position on the limiting stud, thereby achieving height adjustment of the adjusting stud 2.

[0025] For example, the positioning through hole 51 matches the adjusting stud 2 to prevent the adjusting stud 2 from undergoing a large horizontal displacement within the positioning through hole 51, thus ensuring positioning accuracy.

[0026] For example, positioning blocks 5 are provided on the four sides of the fixing plate 1, that is, positioning blocks 5 are provided on both the horizontal and vertical sides of the fixing plate 1, which helps the fixing plate 1 to remain horizontal.

[0027] For example, the fixing plate 1 is a steel plate, which is sturdy and durable.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
