Description

Technical Field

[0001] The utility model relates to the technical field of large-scale equipment installation, in particular to a large-scale equipment installation embedded part. Background Art

[0002] When installing large equipment, high positioning accuracy is required for embedded parts. In the prior art, embedded parts are buried in concrete foundations. The method of burying is generally to first use instruments and equipment for positioning, then tie and fix the embedded parts to the steel bars, and then pour concrete. When pouring concrete, a vibrator is needed to vibrate the concrete to make it dense. In this process, it is inevitable that the embedded parts will be offset due to positioning and layout deviation, vibrator vibration, unilateral inflow of concrete causing steel bar offset, thermal expansion and contraction of steel bars causing expansion and offset, etc., so that the actual position of the embedded parts deviates from the original position, which makes it impossible for the equipment to be aligned with the embedded parts during installation, making it difficult to install the equipment smoothly. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model aims to provide a large-scale equipment installation embedded component to solve the problem that the existing large-scale equipment cannot be aligned with the embedded component during installation.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A large equipment installation embedded part includes a bolt, a bolt sleeve is provided on the part of the bolt buried in the foundation, a plurality of limit plates for limiting the axial movement of the bolt are evenly arranged on the outer side of the bolt along the axial direction of the bolt, a plurality of limit parts are provided on the bolt sleeve to cooperate with the plurality of limit plates, the limit parts are tied to the steel bars in the foundation, and gaps are provided between the bolt and the bolt sleeve and between the limit plates and the limit parts.

[0006] Principle of the utility model:

[0007] In the initial state, the bolt sleeve is arranged at the lower part of the bolt. When using this solution, the bolt sleeve is positioned at a preset position, and concrete is poured after the limiting part is tied to the steel bars in the foundation, so that the bolt sleeve and the foundation form a whole. Due to factors such as vibration of the vibrator and thermal expansion and contraction of the steel bars during the pouring process, the bolt sleeve will be slightly offset. Since there is a gap between the bolt and the bolt sleeve and between the limiting plate and the limiting part, when the bolt sleeve is offset, the gap between the bolt and the bolt sleeve can offset the offset, so that the bolt can be aligned with the mounting hole on the equipment when the equipment is installed, ensuring that the equipment can be installed smoothly.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] 1. This solution sets a gap between the bolt and the bolt sleeve and between the limit plate and the limit part. The gap can offset the offset of the bolt sleeve, so that the bolt can be aligned with the mounting hole on the equipment when installing the equipment, ensuring that the equipment can be installed smoothly.

[0010] 2. This scheme can strengthen the connection between the bolt and the bolt sleeve by setting a number of limit plates, effectively preventing the bolt from falling out of the bolt sleeve; by setting a number of limit parts, on the one hand, the contact area between the bolt sleeve and the concrete can be increased, the friction force can be increased, and the embedded parts can be prevented from being pulled out and damaged; on the other hand, the limit parts can strengthen the anchor connection between the bolt sleeve and the steel bar by being tied with the steel bars in the foundation, which can further improve the pull-out strength between the embedded parts and the foundation.

[0011] As a preferred embodiment of the utility model, a sealing cover is provided at the upper end of the bolt sleeve, a through hole for the bolt to pass through is opened in the middle of the sealing cover, and a blocking portion is provided at the lower end of the sealing cover, which is clamped in the gap between the bolt and the bolt sleeve. Since there is still a long time before the equipment is officially installed after the embedded parts are buried in the foundation, this solution can prevent impurities from entering the gap by setting a sealing cover, and on the other hand, it can keep the bolt and the bolt sleeve relatively fixed to avoid collision between the bolt and the bolt sleeve during transportation.

[0012] As a preferred embodiment of the utility model, the outer edge of the sealing cover is provided with a guide surface. This solution can guide rainwater by providing the guide surface.

[0013] As a preferred embodiment of the utility model, the outer edge of the limit plate is set to a polygon, and the inner side wall of the limit part cooperates with the outer edge of the limit plate to be set to a polygon, and the outer edge of the limit plate can be placed against the inner side wall of the limit part. After the device is inserted with the bolt, the nut needs to be screwed on the top of the device to fix the device. In this solution, the outer edge of the limit plate cooperates with the inner side wall of the limit part to limit the rotation of the bolt when the nut is screwed in, so as to screw the nut.

[0014] As a preferred embodiment of the utility model, the portion of the bolt higher than the foundation is covered with a flexible sleeve, and the lower end of the flexible sleeve is pressed on the lower side of the sealing cover. By arranging the flexible sleeve outside the bolt, the exposed portion of the bolt can be rust-proofed, and the flexible sleeve can be fixed by pressing the lower end of the flexible sleeve with the sealing cover.

[0015] As a preferred embodiment of the utility model, the upper edge of the bolt sleeve is set as a slope. By setting the slope, the concrete can be guided during concrete pouring. As the concrete gradually rises, the concrete reaches the upper end surface of the bolt sleeve under the guidance of the slope and is flush with the upper end surface.

[0022] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0023] In the description of the present application, the terms "top", "bottom", "one end", "one side", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0024] See also Figure 1 As shown, this embodiment discloses a large equipment installation embedded part, including a bolt 2, the part of the bolt 2 buried in the foundation is provided with a bolt sleeve 1, the material of the bolt sleeve 1 is modified PA, and a plurality of limit plates 3 are welded on the outer side of the bolt 2. In this scheme, there are three limit plates 3, and the bolt sleeve 1 is integrally formed with three limit parts 4 in cooperation with the three limit plates 3, and the limit plates 3 cooperate with the corresponding limit parts 4. By providing a plurality of limit plates 3, the connection between the bolt 2 and the bolt sleeve 1 can be strengthened to prevent the bolt 2 from slipping out of the bolt sleeve 1. By providing a plurality of limit parts 4, on the one hand, the contact area between the bolt sleeve 1 and the concrete 11 can be increased, and the friction force can be increased. On the other hand, when the bolt sleeve 1 is buried in the foundation, the limit part 4 can be bundled with the steel bar 10 in the foundation, which can strengthen the anchor connection between the bolt sleeve 1 and the steel bar 10 and improve the pull-out strength between the embedded part and the foundation.

[0025] See also Figure 2 and Figure 3 As shown, there is a gap 5 between the bolt 2 and the bolt sleeve 1 and between the limit plate 3 and the limit part 4. When in use, after the bolt sleeve 1 is positioned at the preset position, the limit part 4 is tied to the steel bar 10 in the foundation, and then the concrete 11 is poured to form the bolt sleeve 1 and the foundation as a whole. The upper edge of the bolt sleeve 1 is set as a slope 6. Under the guidance of the slope 6, the concrete 11 gradually rises to the upper end surface of the bolt sleeve 1 and is flush with the upper end surface. Due to factors such as vibration of the vibrator and thermal expansion and contraction of the steel bars during the pouring of the concrete 11, the bolt sleeve 1 will be slightly offset after the pouring of the concrete 11, resulting in a deviation between the actual position of the bolt sleeve 1 and the preset position. By setting the gap 5 between the bolt 2 and the bolt sleeve 1 and between the limit plate 3 and the limit part 4, the gap 5 can offset the offset of the bolt sleeve 1, ensuring that the equipment 12 can be smoothly inserted into the bolt 2 and installed smoothly.

[0026] See also Figure 4 As shown, the outer edge of the limit plate 3 is set to a polygon, and the inner side wall of the limit part 4 is also set to a polygon in cooperation with the outer edge of the limit plate 3. The outer edge of the limit plate 3 can be placed against the inner side wall of the limit part 4. After the device 12 is inserted into the bolt 2, the nut 13 needs to be screwed on the top of the device 12 to fix the device 12. Through the cooperation between the outer edge of the limit plate 3 and the inner side wall of the limit part 4, the bolt 2 can be limited from rotating when the nut 13 is screwed in, so as to screw the nut 13.

[0027] See also Figure 1 As shown, since there is still a long time before the equipment 12 is formally installed after the embedded parts are buried in the foundation, in order to prevent impurities or water from entering the gap 5 during this period, a sealing cover 7 is also provided at the upper end of the bolt sleeve 1. A through hole matching the bolt 2 is opened in the middle of the sealing cover 7. The bolt 2 passes through the through hole. A sealing portion 8 is integrally formed at the lower end of the sealing cover 7. The sealing portion 8 is clamped in the gap 5 between the bolt 2 and the bolt sleeve 1. The outer edge of the sealing cover 7 is provided with a guide surface 9 to guide rainwater. By providing the sealing cover 7, in addition to preventing impurities or water from entering the gap 5, the bolt 2 and the bolt sleeve 1 can also be kept relatively fixed to avoid collision between the bolt 2 and the bolt sleeve 1 during transportation.

[0028] In other embodiments, the portion of the bolt 2 that is higher than the foundation is covered with a flexible sleeve, and the lower end of the flexible sleeve is pressed on the lower side of the sealing cover 7. In this solution, by arranging the flexible sleeve outside the bolt 2, the exposed portion of the bolt 2 can be rust-proofed, and the sealing cover 7 presses the lower end of the flexible sleeve to fix the flexible sleeve.

[0029] In other embodiments, a vertically arranged grouting pipe is fixed between two adjacent limiting parts 4, the grouting pipe is integrally formed with the limiting part 4, the grouting pipe connects the two adjacent limiting parts 4, and a grouting hole is opened on the upper end surface of the bolt sleeve 1, and the grouting hole connects the uppermost limiting part 4 with the outside. By setting the grouting hole and the grouting pipe, after the bolt 2 is adjusted to a suitable position, cement mortar can be injected from the grouting hole, and the cement mortar enters the gap between the bolt 2 and the bolt sleeve 1, and the limiting plate 3 and the limiting part 4 through the grouting pipe, so that the bolt 2 is sealed in the bolt sleeve 1, so that the bolt 2 and the bolt sleeve 1 are more tightly connected, which can greatly improve the stabilization effect, and at the same time prevent the bolt 2 from rusting and ensure the tensile strength of the bolt 2.

[0030] Specific implementation process:

[0031] In the initial state, the bolt sleeve 1 is sleeved on the lower part of the bolt 2, and the sealing cover 7 is clamped in the gap 5 at the upper end of the bolt sleeve 1, so that the bolt 2 and the bolt sleeve 1 remain relatively fixed. When using this solution, the bolt 2 and the bolt sleeve 1 are positioned at the preset position, the limit part 4 is tied to the steel bar 10 in the foundation, and then the concrete 11 is poured. After the concrete 11 is completely dry, the bolt sleeve 1 and the concrete 11 foundation form a whole. Due to factors such as vibration of the vibrator and thermal expansion and contraction of the steel bars during the pouring process, the bolt sleeve 1 and the bolt 2 will be slightly offset synchronously, resulting in a deviation between the actual fixed position and the preset position.

[0032] When starting to install the device 12, remove the sealing cover 7. At this time, the bolt 2 can move in the bolt sleeve 1. By fine-tuning the bolt 2, the bolt 2 is adjusted back to the preset position to align the bolt 2 with the mounting hole on the device 12. After the device 12 is inserted into the bolt 2, the nut 13 is screwed on the top of the device 12. The upper side of the limit plate 3 is pressed against the inner top wall of the limit part 4, and the device 12 is fixed.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
