Description

Technical Field

[0001] This utility model belongs to the field of positioning technology for steel column base embedded parts, specifically, it relates to an adjustable positioning device for steel column base embedded parts. Background Technology

[0002] In building construction, the pre-embedding of steel column bases is a crucial step in ensuring the stability and safety of steel structure buildings. As an important component connecting the steel column base to the foundation, the installation accuracy of the pre-embedded bolts directly affects the subsequent installation quality of the steel structure and the overall structural stability.

[0003] However, the positioning and fixing of embedded bolts face numerous challenges during actual construction. Especially during concrete pouring, the fluidity of the concrete and the effects of vibration can easily cause the embedded bolts to shift, leading to deviations from design requirements. Furthermore, traditional construction methods typically involve welding the embedded bolts to the reinforcing steel for fixation. While this provides some stability, it also presents difficulties in adjustment. Once the embedded bolts deviate from their position, the adjustment process is complex and time-consuming due to the limitations of welding, making it difficult to meet the requirements of high-precision installation. This technological deficiency not only reduces the installation efficiency of steel column base embedding but also poses potential risks to the overall project quality and safety. Therefore, designing an easily adjustable positioning device for steel column base embedding to effectively solve the problems of easy displacement and difficulty in adjustment of embedded bolts during construction has become an urgent technical challenge.

[0004] Therefore, this utility model proposes an adjustable positioning device for steel column base embedded parts to solve the shortcomings of the existing technology. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide an adjustable positioning device for steel column base embedded parts, so as to solve the problems of easy displacement and difficulty in adjustment during the construction process of existing steel column base embedded parts.

[0006] To achieve the above objectives, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An adjustable positioning device for steel column base embedded parts includes a positioning frame, a connector, and an embedded part positioning component; the positioning frame is the main positioning frame, at least two of which are arranged on the outside of the steel column base embedded parts and fixedly connected to the tied reinforcing bars; the connector is arranged between adjacent positioning frames and connected to the positioning frame; the embedded part positioning component is detachably fixed on the positioning frame and matches the steel column base embedded parts.

[0008] In a preferred embodiment of this utility model, the positioning frame is a rectangular positioning frame, including a plurality of positioning rods and a cross-shaped adapter. The positioning rods are arranged in a cross shape to form the basic support structure of the frame. The cross-shaped adapter is connected to the positioning rods by a connecting bolt.

[0009] In a preferred embodiment of this utility model, the positioning rod is uniformly provided with a plurality of threaded holes and through holes. The threaded holes and through holes are all provided through the side wall of the positioning rod, and the threaded holes and through holes on the same cross section are interconnected. The threaded holes are connected to the embedded positioning parts and the connecting bolts through threaded engagement. The through holes are connected to the connecting parts and the binding steel bars.

[0010] In a preferred embodiment of the present invention, the cross-shaped adapter is provided with two non-communicating through slots, both through slots penetrating the cross-shaped adapter, and the two cross-shaped adapters are arranged in a cross shape.

[0011] In a preferred embodiment of the present invention, the cross adapter is further provided with a positioning hole, which is connected to both of the through slots and threadedly connected to the connecting bolt.

[0012] In a preferred embodiment of this utility model, the connecting member includes a connecting rod and a connecting nut; the connecting rod matches the through hole, and threaded grooves are provided on both ends of the connecting rod to connect with the connecting nut; the connecting nut is located on the upper and lower sides of the positioning rod.

[0013] In a preferred embodiment of this utility model, the embedded part positioning component includes a threaded rod and a pressure plate; the threaded rod is threadedly connected to a threaded hole; the pressure plate is disposed at one end of the threaded rod and matches the embedded part of the steel column base.

[0014] Compared with the prior art, this utility model provides an adjustable positioning device for steel column base embedded parts, which has the following advantages:

[0015] 1. The adjustable positioning device for the steel column base embedded parts achieves precise fine-tuning of the embedded part's position through the threaded connection between the threaded rod of the embedded part and the threaded hole on the positioning rod. During construction, workers can adjust the position of the embedded part by rotating the threaded rod based on actual measurement data. Utilizing the precision of the threaded transmission, the pressure plate makes a slight displacement along the axial direction of the threaded rod, applying precise pushing or pulling forces to the embedded part, gradually adjusting its horizontal and vertical positions until the required accuracy is achieved. Compared to the coarse positioning of traditional devices, this fine-tuning method significantly improves the installation accuracy of the embedded parts and effectively avoids subsequent construction problems caused by inaccurate positioning.

[0016] 2. This device employs a multi-connection and fixing design, enhancing the overall structural stability. Firstly, the positioning frames are connected by threaded rods through through-holes in the positioning rods, secured with connecting nuts on both sides of the positioning rods, forming a stable rectangular frame structure. This connection method effectively fixes the positioning frames in both horizontal and vertical directions, enabling them to withstand various external forces during construction and preventing deformation and loosening. Secondly, the threaded connection between the positioning holes on the cross-shaped adapter and the connecting bolts further strengthens the connection between the positioning rods and the cross-shaped adapter, ensuring the joint strength of the entire positioning frame. Simultaneously, the self-locking characteristics of the threaded rods and holes of the embedded positioning components, along with the large-area contact design between the pressure plate and the surface of the steel column base embedded components, effectively disperse the positioning force, preventing loosening caused by localized stress concentration and ensuring the positional stability of the steel column base embedded components during concrete pouring.

[0017] 3. This device boasts excellent adaptability and flexibility, capable of meeting diverse construction scenarios and design requirements. The positioning frame comprises several positioning rods and cross-shaped adapters, allowing for flexible assembly and adjustment based on the size and shape of the embedded steel column base components. Multiple threaded holes and through holes on the positioning rods provide ample connection points, facilitating the selection of appropriate installation positions and connection methods by construction personnel according to actual conditions. Furthermore, the detachable design of the embedded component positioning components allows for quick replacement and adjustment during construction as needed, accommodating embedded steel column base components of different specifications and shapes. This flexibility enables the device to be widely applied in various construction projects, providing excellent positioning results for both small buildings and large industrial plants.

[0018] 4. This device is relatively easy to operate and can significantly improve construction efficiency. During installation, construction personnel only need to assemble the positioning frame according to the design requirements and fix it with the connectors, and then install the embedded positioning parts into the threaded holes of the positioning rod. When adjusting the position of the embedded parts of the steel column base, fine adjustments can be made simply by rotating the threaded rod, without the need for complex tools and cumbersome operating procedures. Compared with traditional devices, it greatly reduces construction time and labor costs, and improves construction efficiency. At the same time, due to the high positioning accuracy and good stability of this device, it can reduce rework caused by inaccurate positioning, further improving construction efficiency and quality.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0034] The following is combined Figures 1 to 6 This invention describes an adjustable positioning device for steel column base embedded parts.

[0035] An adjustable positioning device for steel column base embedded parts is mainly used for precise positioning of steel column base embedded parts 1 during construction to prevent positional displacement during rebar tying and concrete pouring. It includes positioning frames, connectors 4, and embedded part positioning components 5. At least two positioning frames, serving as the main positioning framework, are arranged on the outside of the steel column base embedded parts 1 and are fixedly connected to the tied rebars during construction, providing positioning for the embedded part positioning components 5. Connectors 4 are positioned between adjacent positioning frames, forming a stable overall positioning structure through connection. The embedded part positioning components 5 are detachably fixed to the positioning frames and work in conjunction with the steel column base embedded parts 1. Through the combined action of multiple embedded part positioning components 5, precise positioning of the steel column base embedded parts 1 is achieved.

[0036] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning frame is a rectangular positioning frame, including several positioning rods 2 and cross-shaped adapters 3. The positioning rods 2 are arranged in a cross shape to form the basic support structure of the frame. The cross-shaped adapters 3 are stably connected to the positioning rods 2 through connecting bolts 6, so that all positioning rods 2 form a complete rectangular positioning frame. This rectangular positioning frame not only provides structural stability for the overall device, but also serves as the installation reference surface for the embedded positioning parts 5, ensuring the accuracy of subsequent positioning operations.

[0037] Specifically, the positioning rod 2 is a square steel pipe, and several threaded holes 21 and through holes 22 are evenly arranged on the positioning rod 2. The threaded holes 21 and through holes 22 are all set through the side wall of the positioning rod 2, and the threaded holes 21 and through holes 22 on the same cross section are interconnected to form a connected structure. This layout not only ensures the connection strength, but also provides convenience for multi-directional assembly. In use, the threaded holes 21 are precisely installed and reliably fixed with the pre-embedded positioning parts 5 and connecting bolts 6 through threaded engagement; the through holes 22 play a dual role: on the one hand, they cooperate with the connecting parts 4 to achieve a stable connection between vertically adjacent positioning rods 2 through an interlocking method; on the other hand, they are connected to the binding steel bars, and the positioning effect of the steel bars is used to ensure the spatial stability of the entire positioning frame during construction, thereby meeting the needs of use under complex working conditions.

[0038] Specifically, the cross-shaped adapter 3 has two non-connecting through slots 31, both of which penetrate the cross-shaped adapter 3. The two cross-shaped adapters 3 are arranged in a cross shape, allowing the adapter to simultaneously position the positioning rods 2 in two mutually perpendicular directions, achieving rapid positioning and initial assembly of the frame nodes. The cross-shaped adapter 3 also has positioning holes 32, which communicate with both through slots 31 and are threadedly connected to the connecting bolts 6. During construction, after the positioning rods 2 are inserted into the through slots 31, the connecting bolts 6 are screwed into the positioning holes 32 and tightened, achieving rigid fixation of adjacent positioning rods 2 at the cross-shaped adapter 3, forming a stable rectangular positioning frame structure.

[0039] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 5As shown, the connector 4 includes a connecting rod 41 and a connecting nut 42. The connecting rod 41 serves as the main connecting element, and its diameter matches the through hole 22 on the positioning rod 2. During construction, it directly passes through the through hole 22 to achieve longitudinal connection of the positioning rod 2, providing a foundation for the connection of the upper and lower positioning rods 2. Threaded grooves are provided on the surfaces of both ends of the connecting rod 41. The connecting nut 42 adopts a double-nut anti-loosening design, and is threaded onto the connecting rod 41 from the upper and lower sides of the positioning rod 2 respectively. By tightening the upper and lower nuts, the positioning rod 2 is clamped between the two nuts, achieving a stable connection between the connecting rod 41 and the positioning rod 2. The interaction of the two nuts effectively prevents loosening of the connection caused by construction vibration, ensuring the overall stability of the positioning frame.

[0040] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the embedded part positioning component 5 includes a threaded rod 51 and a pressure plate 52. The threaded rod 51 is threadedly connected to the threaded hole 21. By rotating the threaded rod 51, its axial feed on the positioning rod 2 can be achieved, providing precise stroke control for position adjustment. The pressure plate 52 is located at one end of the threaded rod 51 and is used in conjunction with the steel column base embedded part 1. During construction, by rotating the threaded rod 51, the pressure plate 52 is pushed towards the embedded part. Under the reference constraint of the positioning frame, a controllable clamping force or pushing force is applied to the steel column base embedded part 1, thereby achieving precise adjustment and fixation of the three-dimensional position of the embedded part.

[0041] The usage process and operating principle of the adjustable positioning device for the steel column base embedded part of this utility model include:

[0042] During the construction preparation phase, the positioning frames are first arranged on the outside of the steel column base embedded parts 1 according to the design spacing, aligning the through holes 22 on the positioning rods 2 with the tied reinforcing bars or connectors 4. The threaded rods 41 of the connectors 4 pass through the through holes 22 and are tightened with the connecting nuts 42 on both the upper and lower sides, connecting the adjacent positioning frames into a stable rectangular frame structure. Subsequently, the threaded rods 51 of the embedded part positioning parts 5 are screwed into the threaded holes 21 of the positioning rods 2. Based on the initial position of the steel column base embedded parts 1, the screwing depth of the threaded rods 51 is initially adjusted so that the pressure plate 52 is close to the surface of the embedded parts. Before the reinforcing bars are tied and the concrete is poured, the threaded rods 51 are precisely rotated, and the pressure plate 52 is used to apply precise pushing or pulling forces to the steel column base embedded parts 1, gradually adjusting their horizontal position and verticality until the design accuracy requirements are met. Finally, all connectors are tightened again to ensure that the entire positioning device remains stable during construction.

[0043] The core principle of this device is to achieve precise positioning and dynamic adjustment of embedded parts through the synergistic effect of modular components. The positioning frame, as the basic framework, forms spatial rigidity through the connector 4, providing a stable positioning reference for the embedded parts. The through-hole design of the cross-shaped adapter 3 and the positioning rod 2 ensures the strength of the frame nodes and the flexibility of assembly. The embedded part positioning component 5 utilizes a threaded transmission mechanism to convert rotational motion into linear displacement of the pressure plate 52. By controlling the screw-in amount of the threaded rod 51, micron-level adjustments to the position of the steel column base embedded part 1 can be achieved. Simultaneously, the large-area contact design between the pressure plate 52 and the surface of the embedded part effectively disperses the positioning force, avoiding deformation caused by localized stress concentration. The entire device, through the dual protection of mechanical interlocking and threaded self-locking, ensures the positional stability of the embedded parts during concrete pouring, ultimately achieving high-precision installation of the steel column base embedded part 1.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
