Description
Technical Field
[0001] This utility model belongs to the field of building engineering, and specifically relates to a bolt installation and fixing device for converter station foundation. Background Technology
[0002] With social progress, the development of power technology, and the national "West-to-East Power Transmission" strategy, the construction of converter stations has become an indispensable and crucial component. Given the diverse foundation types and high precision requirements within converter stations, the accuracy of bolt pre-embedding directly determines the success or failure of civil construction. For a large number of bolts, and the potential for slippage and settlement during concrete pouring and vibration, conventional pre-embedded bolt installation methods cannot effectively solve these problems. This leads to difficulties in later equipment installation, bolt maintenance, and unnecessary economic losses.
[0003] To address the above issues, we propose a bolt mounting and fixing device for converter station foundations. Utility Model Content
[0004] To address the aforementioned problems in the prior art, namely the slippage and subsidence that easily occur during concrete pouring and vibration, this utility model provides a converter station foundation bolt installation and fixing device, which includes: an angle steel bracket, a connecting plate, a sleeve, and fixing bolts;
[0005] The angle steel bracket is fixed to the construction frame, and a first elongated hole is provided on the angle steel bracket;
[0006] The connecting plate is fixed to the outer surface of the sleeve, the sleeve overlaps the angle steel bracket, and a second elongated hole is provided on the connecting plate along its length.
[0007] The sleeve is installed on the pre-embedded bolt;
[0008] The fixing bolt passes through the first elongated hole and the second elongated hole and moves along its length.

[0014] The middle layer support includes a fourth angle steel and a fifth angle steel;
[0015] The lower support structure includes a sixth angle steel, a seventh angle steel, and an eighth angle steel;
[0016] The first angle steel is fixed perpendicularly to one end of the second angle steel, and the other end of the second angle steel is fixed perpendicularly to the third angle steel.
[0017] One end of the fourth angle steel is fixed perpendicularly to one end of the first angle steel and / or the second angle steel, and the other end of the fourth angle steel is fixed perpendicularly to one end of the sixth angle steel and / or the seventh angle steel. One end of the fifth angle steel is fixed perpendicularly to the other end of the second angle steel and / or the third angle steel, and the other end of the fifth angle steel is fixed perpendicularly to the other end of the seventh angle steel and / or the eighth angle steel.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] like Figure 1 and Figure 2 As shown, this utility model provides a converter station foundation bolt installation and fixing device, which includes: angle steel bracket 1, connecting plate 2, sleeve 3, and fixing bolt 4;
[0034] The angle steel bracket 1 is fixed to the construction frame, and a first elongated hole 11 is provided on the angle steel bracket 1;
[0035] The connecting plate 2 is fixed to the outer surface of the sleeve 3. The sleeve 3 overlaps the angle steel bracket 1. A second elongated hole 21 is provided on the connecting plate 2 along its length.
[0036] The sleeve 3 is installed on the pre-embedded bolt;
[0037] The fixing bolt 4 passes through the first elongated hole 11 and the second elongated hole 21 and moves along its length.
[0038] Bolt 4 is a standard bolt set.
[0039] In this embodiment, the angle steel bracket 1 is fixedly connected to the external construction frame by welding. A first elongated hole 11 is provided on the upper surface of the angle steel bracket 1. The connecting plate 2 is made of steel plate material, and one end of it is welded and fixed perpendicularly to the outer peripheral wall of the sleeve 3, so that the sleeve 3 is supported on the angle steel bracket 1 by the connecting plate 2. A second elongated hole 21 is provided on the connecting plate 2 along its length direction. The sleeve 3 is a metal cylinder with internal threads, which is fitted over the pre-embedded bolt 5 during construction. The fixing bolt 4 passes through the first elongated hole 11 on the angle steel bracket 1 and the second elongated hole 21 on the connecting plate 2 in sequence, and the connecting plate 2 is pressed and fixed on the angle steel bracket 1 by the matching nut. Before tightening the fixing bolt 4, the connecting plate 2 can drive the sleeve 3 to move along the length direction of the first elongated hole 11 and the second elongated hole 21, thereby realizing the precise adjustment of the installation position of the pre-embedded bolt 5.
[0040] As a further explanation of this utility model, the angle steel bracket 1 includes an upper bracket, a middle bracket, and a lower bracket;
[0041] The upper support and the lower support are fixed together by a middle support, and the connecting plate 2 overlaps on the upper support and the lower support respectively;
[0042] Both the upper support and the lower support are provided with a first elongated hole 11.
[0043] In this embodiment, the angle steel bracket 1 adopts a layered structure design, mainly composed of an upper bracket, a middle bracket, and a lower bracket. The upper and lower brackets are connected and fixed through the middle bracket to form a stable three-dimensional support frame. Two connecting plates 2 are provided, which overlap and support the upper and lower brackets at corresponding positions. First elongated holes 11 are machined on the surface of both the upper and lower brackets. These elongated holes extend along the length of the bracket, providing guidance for adjusting the bolt positions. This layered structure design not only enhances the overall rigidity and stability of the angle steel bracket but also provides two fixing planes for the connecting plates, making the fixing of the pre-embedded bolts more secure and reliable.
[0044] The upper and lower supports are arranged horizontally, while the middle support is arranged vertically.
[0045] More specifically, the upper support includes a first angle steel 111, a second angle steel 112, and a third angle steel 113;
[0046] The middle layer support includes a fourth angle steel 121 and a fifth angle steel 122;
[0047] The lower support includes a sixth angle steel 131, a seventh angle steel 132, and an eighth angle steel 133;
[0048] The first angle steel 111 is perpendicularly fixed to one end of the second angle steel 112, and the other end of the second angle steel 112 is perpendicularly fixed to the third angle steel 113;
[0049] One end of the fourth angle steel 121 is perpendicularly fixed to one end of the first angle steel 111 and / or one end of the second angle steel 112, and the other end of the fourth angle steel 121 is perpendicularly fixed to one end of the sixth angle steel 131 and / or one end of the seventh angle steel 132. One end of the fifth angle steel 122 is perpendicularly fixed to the other end of the second angle steel 112 and / or the third angle steel 113, and the other end of the fifth angle steel 122 is perpendicularly fixed to the other end of the seventh angle steel 132 and / or the eighth angle steel 133.
[0050] The sixth angle steel 131 is perpendicularly fixed to one end of the seventh angle steel 132, and the other end of the seventh angle steel 132 is perpendicularly fixed to the eighth angle steel 133;
[0051] Both the second angle steel 112 and the seventh angle steel 132 have a first elongated hole 11 along their length on the upper facade, and both are connected to the connecting plate 2.
[0052] In this embodiment, all angle steel components are rigidly connected by welding, ensuring the stability and load-bearing capacity of the overall structure. This design allows the angle steel bracket to provide reliable multi-point support for the pre-embedded bolts, while the elongated holes enable precise adjustment of the installation position.
[0053] Through a three-layer frame design consisting of upper, middle, and lower supports, and with multiple angle steels vertically fixed at various nodes, a stable spatial three-dimensional support frame is formed. This structure significantly improves the overall rigidity and load-bearing capacity of the angle steel supports, enabling them to effectively resist various construction loads during concrete pouring and vibration, preventing deformation or displacement of the supports, and providing a stable and reliable fixing foundation for the pre-embedded bolts.
[0054] By setting elongated holes on angle steel at two different levels, a more stable multi-point fixing method is provided for the pre-embedded bolts, which significantly reduces the possibility of bolts shifting, settling or rotating during concrete pouring, and ensures that the final installation position of the pre-embedded bolts meets the design requirements.
[0055] Assembled using standardized angle steel components, this modular design facilitates rapid on-site assembly and adjustment, while reducing manufacturing costs. This structural design ensures the integrity of the support structure while providing flexible adaptability for the arrangement of pre-embedded bolts of different specifications.
[0056] Both connecting plates 2 are fixed to the outer surface of the sleeve 3 to achieve connection stability.
[0057] As a further explanation of this utility model, the length direction of the first elongated hole 11 intersects the length direction of the second elongated hole 21, preferably perpendicularly in this embodiment. This orthogonal arrangement forms a two-dimensional planar adjustment system, allowing operators to loosen the fixing bolts 4, enabling the connecting plate 2 to move the sleeve 3 and the pre-embedded bolts 5 independently in the horizontal plane in both forward and backward and left and right directions. This adjustment method greatly improves the positioning accuracy of the pre-embedded bolts, allowing construction personnel to adjust the position in each direction step by step, ultimately precisely adjusting the bolts to the design coordinate points before locking them in place. This design effectively solves the problem that traditional fixing devices can only be adjusted in one direction or cannot be fine-tuned, significantly improving the installation quality and reliability of the converter station foundation bolts, while ensuring the displacement resistance and overall stability of the pre-embedded bolts during concrete pouring.
[0058] As a further explanation of this utility model, the sleeve 3 is a mechanical connection sleeve, used to be fitted onto the pre-embedded bolts before construction. This further avoids damage and contamination of the bolts.
[0059] As a further explanation of this utility model, the connecting plate 2 is used to connect the angle steel bracket 1 and the sleeve 3. The length direction of the connecting plate 2 is perpendicular to the axial direction of the sleeve 3.
[0060] In this embodiment, the design of the connecting plate 2 being perpendicular to the axis of the sleeve 3 creates an effective lever arm transmission mechanism. This structure effectively transmits the lateral force and vibration impact generated during concrete pouring to the angle steel bracket 1 via the connecting plate 2, avoiding stress concentration at the connection between the sleeve 3 and the connecting plate 2, and greatly improving the impact resistance and stability of the entire fixing device. When the embedded bolt is subjected to torque, the vertically arranged connecting plate 2 provides a larger anti-torsional moment, effectively preventing the sleeve 3 and the embedded bolt from rotating or deflecting during construction, ensuring the accuracy of the bolt installation angle. The vertical connection between the connecting plate 2 and the sleeve 3 allows the operator to directly and precisely control the horizontal position of the sleeve 3 and the embedded bolt by adjusting the position of the connecting plate 2 in the elongated hole of the angle steel bracket 1. This one-to-one correspondence greatly simplifies the adjustment process and improves construction efficiency.
[0061] As a further explanation of this utility model, the upper facade bolt centerline of the second angle steel 112 and the seventh angle steel 132 is engraved with a groove.
[0062] By precisely carving grooves at the centerline of the angle steel facade bolts, a clear visual and tactile positioning benchmark was provided for the installation of fixing bolt 4. Construction personnel could quickly and accurately align the fixing bolts to the installation position, greatly improving installation efficiency and avoiding positioning deviations caused by blind operation.
[0063] The slotted structure provides mechanical restraint, effectively preventing the fixing bolts from accidentally sliding along the angle steel surface during tightening and concrete vibration. This mechanical interlocking significantly improves the connection reliability between the connecting plate 2 and the angle steel bracket 1, ensuring the long-term stability of the embedded bolt positions.
[0064] The groove serves as a visible quality control marker, allowing supervisors to intuitively check whether the fixing bolts are installed in place. This improves the controllability and inspectability of construction quality and provides a clear basis for project quality acceptance.
[0065] In a specific embodiment of this utility model, the converter station foundation bolt mounting and fixing device adopts a modular combination installation. Preferably, four sets of this fixing device are provided in this embodiment. These four sets of devices are vertically fixed and connected sequentially using angle steel brackets 1, forming a rectangular rigid closed-loop support frame.
[0066] In practice, four angle steel supports 1 are respectively arranged at the four corner points of the rectangular foundation. Adjacent angle steel supports are vertically fixed by welding or bolting through their lateral connecting surfaces to ensure the structural integrity of the entire rectangular frame. Each angle steel support 1 has a first elongated hole 11 on its second angle steel 112 and seventh angle steel 132, and a sleeve 3 and a pre-embedded bolt 5 are installed through a connecting plate 2 and a fixing bolt 4.
[0067] This rectangular closed-loop frame structure significantly enhances the system rigidity and stability of the entire fixing device, effectively resisting all-directional loads generated during concrete pouring and vibration. Simultaneously, the pre-embedded bolts 5 at the four corner positions can be independently and precisely adjusted in two dimensions through their corresponding elongated holes, ensuring the positional accuracy and installation quality of the entire foundation bolt assembly. This modular design not only meets the support requirements of large foundation structures but also provides flexible adjustment capabilities, significantly improving construction efficiency and quality reliability.
