Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete foundation construction technology, and in particular to an installation and alignment device for T-bolts on large equipment foundations. Background Technology
[0002] During the installation of large equipment, concrete foundations are required to facilitate the subsequent installation of the equipment, reduce vibration, absorb vibration energy generated during operation, fix the equipment's position, and prevent displacement during operation.
[0003] When laying foundations for large equipment, T-bolt sleeves must be pre-embedded before installing the T-bolts and the large equipment. However, in actual projects, there is a problem with insufficient stability in sleeve positioning. Specifically, in traditional processes, the fixing of T-bolt sleeves often relies on temporary support structures or simple anchoring measures, lacking a dedicated stable support system. During rebar tying, concrete pouring, and vibration, the sleeves are easily disturbed by external forces, such as the impact of the vibrator or the lateral pressure of the concrete, causing displacement or tilting, leading to loss of accuracy in the pre-embedded position. This deviation may cause problems such as difficulty in bolt hole alignment and stress concentration in the equipment base during later equipment installation, even requiring rework and significantly increasing construction costs and schedule risks. Furthermore, existing T-bolt alignment frames are welded to the surface rebar; such alignment frames are susceptible to deformation due to pedestrian traffic or object impacts, resulting in inaccurate bolt sleeve positioning. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an installation and alignment device for T-bolts of large equipment foundations. It is mainly used for the installation of large equipment foundations to achieve the purpose of installing and fixing the T-bolt sleeves and improving the accuracy of alignment and installation, thereby facilitating the installation of large equipment.
[0005] This utility model discloses an installation and alignment device for T-bolts on large equipment foundations, comprising vertically arranged support columns, four of which enclose a T-bolt sleeve installation cavity, wherein a T-bolt sleeve is provided within the installation cavity, and each support column includes a pre-embedded section and an extension section connected in sequence, wherein the pre-embedded section is disposed within secondary poured concrete, and a tie beam is provided between two adjacent pre-embedded sections at intervals along the length of the pre-embedded section, one side of the T-bolt sleeve being fixedly connected to the tie beam, the extension section being disposed above the secondary poured concrete, and an alignment line frame beam is provided between two adjacent extension sections, with an alignment hanging line provided between the alignment line frame beams.
[0006] Furthermore, a tie beam is provided between two adjacent extension sections, located below the alignment frame crossbeam, and the tie beam is arranged parallel to the alignment frame crossbeam between the two adjacent extension sections.
[0007] Furthermore, the top of the extension is located 500mm above the secondary poured concrete.
[0008] Furthermore, the embedded section is also provided with an inclined support located in the secondary concrete pouring, one end of which is connected to the embedded section and the other end is connected to the ground.
[0009] Furthermore, there are two tie beams. One tie beam is set 500mm away from the upper surface of the secondary concrete in the pre-embedded section, and the other tie beam is set 500mm above the bottom of the T-bolt sleeve in the pre-embedded section.
[0010] The beneficial effects of this utility model are as follows: The alignment device uses a support column including a pre-embedded section and an extension section as an installation and fixing device for the T-bolt sleeve. It can not only fix the installation position of the T-bolt sleeve, but also be used as an alignment frame when aligning the T-bolt sleeve. The fixing device of the T-bolt sleeve is shared with the alignment frame, which reduces material consumption and improves the construction time of secondary layout. The pre-embedded section is stable and improves the accuracy control, making construction quick and convenient. Attached Figure Description

Detailed Implementation
[0015] The present invention will be further described below.
[0016] This utility model provides an installation and alignment device for T-bolts on large equipment foundations, mainly used for the installation of large equipment foundations. It includes vertically arranged support columns 1, and four support columns 1 enclose a T-bolt sleeve 6 installation cavity 13. The installation cavity 13 is provided with T-bolt sleeves 6. Each support column 1 includes a pre-embedded section 11 and an extension section 12 connected in sequence. The pre-embedded section 11 is set in the secondary poured concrete. A tie beam 2 is provided between two adjacent pre-embedded sections 11 and spaced along the length of the pre-embedded section 11. One side of the T-bolt sleeve 6 is fixedly connected to the tie beam 2. The extension section 12 is set above the secondary poured concrete. An alignment frame beam 4 is provided between two adjacent extension sections 12, and an alignment hanging line 41 is provided between the alignment frame beams 4.
[0017] like Figure 1 , Figure 2As shown, the alignment device for the T-bolts of the large equipment foundation includes a vertically arranged support column 1. The support column 1 includes a pre-embedded section 11 and an extension section 12. The pre-embedded section 11 is set in the secondary concrete pouring to provide stable foundation support. The extension section 12 is located above the secondary concrete pouring to facilitate the operation and installation of the alignment guide 41 for subsequent adjustment of the horizontal and vertical dimensions of the T-bolts. A tie beam 2 is also provided between two adjacent pre-embedded sections 11. The number and spacing of the tie beams 2 can be adjusted according to the length of the pre-embedded section 11. The installation is configured by setting a tie beam 2 between two pre-embedded sections 11, thus forming a stable frame structure between the supporting columns 1 and the tie beam 2. The four supporting columns 1 enclose a T-bolt sleeve 6 mounting cavity 13, and one side of the T-bolt sleeve 6 is welded to the tie beam 2 to achieve bidirectional constraint. This ensures that the T-bolt sleeve is fixed in both the horizontal and vertical directions, preventing horizontal displacement of the T-bolt sleeve 6 due to concrete pouring, vibration, etc., and ensuring the installation accuracy of the T-bolt. That is, the pre-embedded section 11 cooperates with the tie beam 2 to form a stable frame structure between the supporting columns 1 and the tie beam 2. Beam 2 serves as the installation and fixing device for the T-bolt sleeve 6, ensuring that it will not shift horizontally due to concrete pouring, vibration, etc. Furthermore, the extension section 12 is positioned above the secondary concrete surface, and a leveling beam 4 is provided between two adjacent extension sections 12 to facilitate the subsequent installation of the leveling line 41, eliminating the need for an additional leveling frame and saving construction time and costs. Moreover, the lower part of the extension section 12 is a pre-embedded section 11 embedded in the secondary concrete, which, after solidification, is not easily shifted due to human footing or collisions. To ensure the stability of the alignment line and the installation accuracy of the T-bolt sleeve 6, the alignment device uses a support column 1, including a pre-embedded section 11 and an extension section 12, as the installation and fixing device for the T-bolt sleeve 6. This not only fixes the installation position of the T-bolt sleeve 6, but also serves as an alignment line frame during the alignment of the T-bolt sleeve 6. The fixing device for the T-bolt sleeve 6 is shared with the alignment line frame, reducing material consumption and improving the construction time for secondary layout. The pre-embedded section 11 provides stability and improves accuracy control, making construction quick and convenient.
[0018] The method of using the T-bolt alignment device for the large equipment foundation is as follows: The large equipment foundation is poured in three stages. In the second stage of concrete pouring, a pre-embedded section 11 of the support column 1 is deeply embedded. The four support columns 1 enclose a T-bolt sleeve 6 mounting cavity 13. The support columns 1 can be made of 12# channel steel. Two tie beams 2 are welded between adjacent support columns 1. The tie beams 2 can be made of 50° angle steel. Specifically, one tie beam 2 is welded to the pre-embedded section 11 500mm from the upper surface of the second stage of concrete pouring, and the other tie beam 2 is welded to the pre-embedded section 11 500mm above the bottom of the T-bolt sleeve 6. The T-bolt sleeve 6 is then placed close to the tie beam 2. One side is welded to the tie beam 2, so that the T-bolt sleeve 6 is fixed in both the horizontal and vertical directions and will not shift during concrete pouring, vibration, and extrusion. If the embedded section 11 is too long, angle steel can be set as a diagonal support 3 in the longitudinal / transverse direction of the embedded section 11. An extension section 12 is provided above the embedded section 11, which is located above the concrete surface. The extension section 12 is 500mm long and located above the concrete surface. A leveling beam 4 is provided on the extension section 12 for hanging the leveling line. After the T-bolt sleeve 6 is aligned, the extension section 12 is cut. The cut-off position is 50mm below the concrete surface or at the same height as the surface reinforcement, so as to facilitate the subsequent installation of T-bolts and equipment.
[0019] Furthermore, to ensure the stability of the connection between the extension sections 12, and to prevent displacement due to the vibration of the concrete below, which could cause the embedded section 11 connected below to tilt, such as... Figure 2 As shown, a tie beam 5 is also provided between two adjacent extension sections 12, located below the alignment frame crossbeam 4. The tie beam 5 is parallel to the alignment frame crossbeam 4 and is provided between two adjacent extension sections 12. By adding the tie beam 5, a double-layer protective structure is formed, which enhances the deformation resistance of the structure.
[0020] To facilitate the installation of the alignment frame beam 4 and the tie beam 5, and to save materials, the top of the extension section 12 is located 500mm above the secondary concrete pouring. Specifically, since the extension section 12 needs to be cut to the same height as the steel reinforcement layer after the bolts are aligned, to avoid cutting too much of the extension section 12, the length of the extension section 12 is designed to be 500mm above the secondary concrete pouring. This allows for the installation of the alignment frame beam 4 and the tie beam 5 while saving materials and avoiding excessive waste.
[0021] To avoid the embedded section 11 being too long, which could lead to unstable installation of the support column 1, such as... Figure 1As shown, the embedded section 11 is also provided with a diagonal support 3 located in the secondary concrete pouring. One end of the diagonal support 3 is connected to the embedded section 11, and the other end is connected to the ground. By adding a diagonal support 3 with one end connected to the ground and the other end connected to the embedded section 11, the diagonal support 3, the embedded section 11, and the ground form a triangular support, which disperses the impact force on the support column 1 during concrete pouring, prevents the column from tilting, ensures the stability of the T-bolt sleeve 6 installation cavity 13, avoids deformation, and ensures the installation accuracy of the T-bolt.
[0022] Furthermore, to eliminate the risk of the T-bolt sleeve 6 floating under the buoyancy of concrete, such as... Figure 1 As shown, there are two tie beams 2. One tie beam 2 is set at 500mm from the upper surface of the secondary concrete in the embedded section 11, and the other tie beam 2 is set at 500mm above the bottom of the T-bolt sleeve 6 in the embedded section 11. By welding one tie beam 2 at 500mm from the upper surface of the secondary concrete in the embedded section 11 and another tie beam 2 at 500mm above the bottom of the T-bolt sleeve 6, and then welding one side of the T-bolt sleeve 6 to the two tie beams 2 in sequence, bidirectional constraint is achieved, so that the T-bolt sleeve is completely fixed in both the horizontal and vertical directions, ensuring the installation stability of the T-bolt sleeve 6 and preventing vertical displacement due to concrete pouring, vibration, etc.
