Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable pre-embedded bolt end positioning component. Background Technology

[0002] In modern construction engineering, especially at the junction of steel and concrete structures, it is usually necessary to position one end of the pre-embedded bolt using a positioning plate before pouring the concrete component. The positioning plate is embedded in the concrete as a reference component. The positioning accuracy of the pre-embedded bolt includes its planar position and verticality. However, during construction, concrete pouring or other construction procedures can affect the positioning accuracy of the free end of the pre-embedded bolt. Any deviation may cause the steel structure component to fail to be accurately positioned, thus affecting the subsequent installation of the steel structure and requiring costly on-site corrections, which seriously affects the construction progress and project quality.

[0003] To ensure that the position of the embedded bolts remains stable during the concrete pouring process, various types of positioning seats or positioning clamps are commonly used for temporary fixing during construction. However, when facing projects that include components with various cross-sectional dimensions, construction units must prepare multiple sets of positioning tools of different specifications. This not only increases the procurement and management costs of the tools but also reduces the utilization rate of the tools.

[0004] Furthermore, to ensure stable positioning, these traditional positioning seats typically employ welded or integral frames, resulting in robust structures that are bulky and immutable. When construction is completed or the equipment is idle, these cumbersome tools occupy significant storage space. Simultaneously, their large size significantly increases the difficulty and cost of transportation between different construction sites, reducing the overall efficiency of on-site tool management.

[0005] Therefore, there is an urgent need to develop an adjustable pre-embedded bolt end positioning component to solve the problems of inconvenient storage and transportation caused by pre-embedded bolts, structural rigidity, and large size in the existing technology. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an adjustable pre-embedded bolt end positioning component to solve the problems of poor versatility and inability to adapt to pre-embedded positioning plates of different lengths due to the fixed structure of the pre-embedded bolt positioning seat in the prior art, as well as the inconvenience of storage and transportation caused by the rigid structure and large size.

[0007] This utility model discloses an adjustable pre-embedded bolt end positioning assembly, comprising two hinged adjustment positioning units. Each adjustment positioning unit includes an adjustment plate and a fixing component. The adjustment plate is slidably mounted on the fixing component. The adjustment plate is provided with a plurality of positioning holes for inserting the end of the pre-embedded bolt, and the adjustment plate can be slidably adjusted to accommodate pre-embedded bolts of different widths.

[0008] Furthermore, the fixing component is a U-shaped groove, the adjusting plate is fastened in the U-shaped groove, and a sliding mechanism is provided between the side wall of the U-shaped groove and the adjusting plate to realize the relative sliding of the adjusting plate and the fixing component.

[0009] Furthermore, the sliding mechanism includes a slide groove and a roller, which are respectively mounted on the fixed component and the adjusting plate, and their mounting positions are interchangeable.

[0010] Furthermore, the U-shaped groove sidewall of the fixing component is also provided with several locking holes for locking the adjustment plate.

[0011] Furthermore, the adjusting plate is also provided with a locking mechanism, which includes a transmission rod and locking rods located on both sides of the transmission rod. One end of the transmission rod is hinged to the two locking rods, and the free end of the locking rod can be driven to insert into or pull out of the locking hole.

[0012] Furthermore, the transmission rod is disposed in a through hole opened along the central axis of the adjustment plate and can be driven to slide within the through hole. The other end of the transmission rod forms a button that can be pressed on the side wall of the adjustment plate and is provided with a return spring that applies preload.

[0013] Furthermore, the locking rod is set in the inclined groove opened on the adjustment plate, and forms an acute or obtuse angle with the transmission rod. At the same time, the locking rod is also provided with a rotating shaft, so that the locking rod can swing around the rotating shaft under the drive of the transmission rod, so that the free end of the locking rod can be inserted into or pulled out of the locking hole.

[0014] Furthermore, the fixing component is provided with a hinge that connects to the fixing component of another adjustment and positioning unit, and the two adjustment and positioning units can be folded or unfolded through a pin.

[0015] Furthermore, the other end of the fixing component with the hinge is also provided with a locking element for locking the folded state.

[0016] The beneficial effects of this utility model are as follows: The adjustable pre-embedded bolt end positioning component of this utility model, by setting a slidingly mating adjustment plate and a fixing component, and locking or releasing the adjustment plate through a locking mechanism, solves the problem of poor versatility of the positioning seat due to its structural fixation in the prior art. It can quickly adjust and lock the length to adapt to pre-embedded bolts with different widths, significantly improving the technical effect of tool versatility and reusability, and preventing the pre-embedded bolts from being displaced or deformed due to external forces or other factors during subsequent construction, thus avoiding affecting the subsequent construction progress. At the same time, the folding structure effectively reduces the storage volume of the equipment, facilitates warehousing and transportation, and improves the efficiency of tool management on the construction site.

[0022] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a cross-sectional schematic diagram of the present invention. Figure 3 The figure shows a partial cross-sectional view of the present invention: This embodiment provides an adjustable pre-embedded bolt end positioning component, mainly used for the precise installation and positioning of pre-embedded bolts 15 in construction engineering. It includes two hinged adjustment and positioning units, each comprising an adjustment plate 1 and a fixing component 2. The adjustment plate 1 is slidably mounted on the fixing component 2, and its surface has multiple positioning holes 3 according to engineering requirements. These positioning holes 3 can be used to accurately fix the end of the pre-embedded bolt 15. By sliding the adjustment plate 1 laterally on the fixing component 2, the relative distance between the positioning holes 3 on the two adjustment plates 1 can be flexibly adjusted, thereby adapting to the installation requirements of pre-embedded bolts 15 of different widths, effectively improving the versatility and applicability of the component. In use, the positioning component is adjusted to match the width of the pre-embedded bolt 15. After the pre-embedded bolt 15 is fixedly installed at one end embedded in the concrete, the positioning holes 3 on the adjustment plate 1 are used to position and restrict the protruding end (the end not embedded in the concrete) of the pre-embedded bolt 15, preventing the pre-embedded bolt 15 from protruding. In subsequent construction, external forces and other factors may cause displacement or changes in the protruding end of the pre-embedded bolt 15, so as to avoid affecting the subsequent construction progress and reducing construction efficiency.

[0023] In this embodiment, the fixing component 2 specifically adopts a U-shaped groove structure. The U-shaped groove is composed of a bottom plate and two side walls. The adjusting plate 1 is embedded in the U-shaped groove in a snap-fit ​​manner to form a stable nested structure. In order to achieve smooth relative movement between the adjusting plate 1 and the fixing component 2, a special sliding mechanism is provided between the inner surface of the side wall of the U-shaped groove and the side of the adjusting plate 1. This not only ensures the smoothness of the movement of the adjusting plate 1, but also effectively reduces frictional resistance, making the adjustment process more effortless and convenient.

[0024] The sliding mechanism specifically consists of a slide groove 5 and a roller 6. The slide groove 5 is a straight guide groove arranged along the moving direction of the adjusting plate 1, and the roller 6 is mounted in the corresponding position by bearings. It should be noted that the mounting positions of the slide groove 5 and the roller 6 can be interchanged according to actual needs. That is, the slide groove 5 can be set on the fixed component 2 and the roller 6 can be mounted on the adjusting plate 1, or the opposite configuration can be used. This interchangeable design greatly improves the assembly flexibility and maintenance convenience of the components.

[0025] In this embodiment, a plurality of equally spaced locking holes 4 are provided on the side wall of the U-shaped groove of the fixing component 2. The locking holes 4 are arranged along the sliding direction of the adjusting plate 1 to form a plurality of reliable fixing points, ensuring that the adjusting plate 1 can be firmly locked in any position.

[0026] This embodiment also includes a locking mechanism, which includes a transmission rod 9 and locking rods 10 symmetrically arranged on both sides. One end of the transmission rod 9 is hinged to both locking rods 10. The axial movement of the transmission rod 9 can synchronously drive the locking rods 10 on both sides to move in opposite directions, thereby realizing the action of the free ends of the locking rods 10 simultaneously inserting or withdrawing from the locking hole 4. This linkage design ensures the synchronicity of locking on both sides and greatly improves the operating efficiency.

[0027] In this embodiment, the transmission rod 9 is installed in a through hole opened along the central axis of the adjusting plate 1, and can slide axially within the through hole. The other end of the transmission rod 9 extends to the outside of the side wall of the adjusting plate 1, forming a button 7 for easy operation. To ensure the stability of the locking mechanism in the non-operating state, a return spring 8 is also provided. The return spring 8 can apply a continuous preload to the transmission rod 9 to keep the locking rod 10 in a normally locked state and prevent accidental loosening.

[0028] In this embodiment, the locking rod 10 is set in a specially opened inclined groove 12 on the adjusting plate 1, forming a certain inclination angle with the transmission rod 9. This angle can be designed as an acute angle or an obtuse angle according to actual needs. At the same time, the locking rod 10 is provided with a rotating shaft 11 in the middle, which allows it to swing around the rotating shaft 11 at a limited angle. When the button 7 is pressed to drive the transmission rod 9 to move, the locking rod 10 can be rotated around the rotating shaft 11 through the transmission of the hinge point, realizing the insertion or withdrawal action of its free end, and completing the switching of the locking state.

[0029] In this embodiment, a hinge connection mechanism is also provided between the fixed components 2 of the two adjustment and positioning units. The two fixed components 2 are hinged by the pin 13, so that the two adjustment and positioning units can rotate relative to each other around the pin 13 to realize the folding or unfolding of the components. This design is particularly beneficial for the storage, transportation and storage of the equipment, saving space.

[0030] In addition, a special locking element 14 is provided at the other end of the fixed component 2 where the hinge is located. When the component is in the folded state, the two adjustment and positioning units can be reliably locked together by the locking element 14 to prevent them from automatically unfolding during handling or storage, thus ensuring the safety and integrity of the equipment.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
