Description

Technical Field

[0001] This utility model belongs to the field of cement prefabricated product technology, specifically a chassis for cement prefabricated products. Background Technology

[0002] Cement products are various building materials and components made from cement as the main raw material. There are many types of cement products, such as hollow concrete slabs, which are often used in the floor slabs of high-rise buildings and large structures. They have several cavities inside, which can reduce the self-weight of the slab and improve the structural economy without weakening the load-bearing capacity. Solid concrete slabs are mostly used in industrial buildings and some special-purpose structures. They have strong load-bearing capacity and are suitable for high-load and high-strength environments. Cement poles are also a common type of cement product. During their manufacturing, a base is often required to connect the bottom of the cement pole, which facilitates the installation of the cement pole.

[0003] In the prior art, Chinese patent CN216893752U discloses a reinforced chassis structure for power cement pole foundations, relating to the field of power pole technology. It solves the problems of laborious handling, wasted space during transportation, and inconvenient operation when disassembling cement poles in current power cement pole chassis. The structure includes a fixed base plate; six auxiliary fixing plates are arranged in a ring on the top of the fixed base plate; a cement pole fixing cylinder is fixedly installed at the center of the top of the fixed base plate using two sets of fastening bolts and nuts; and six clamping rods are inserted in a ring inside the cement pole fixing cylinder.

[0004] However, the reinforced chassis structure for cement pole foundations provided in the above technical solutions still has many shortcomings in actual application. For example, when reinforcing the bottom of the cement pole, its structure is fixed and cannot be adjusted, making it unsuitable for cement poles of different sizes, resulting in poor applicability.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the use of the first threaded rod on the rotating side plate and the telescopic rod, allows the pressure plate to move closer to the cement pole at the center of the circular frame, so that the pressure plate presses against cement poles of different diameters, thereby clamping the cement poles of different diameters, enhancing the stability of the bottom of the cement pole, and also making the device applicable to cement poles of different diameters, thus improving the applicability of the device.

[0016] This invention allows for adjustment of the height of the pressure block by rotating the second threaded rod in conjunction with the use of the threaded cylinder.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] Please see Figure 1-5 The present invention provides an embodiment of a base for a precast cement product, comprising a mounting plate 1, a through hole in the center of the mounting plate 1, a circular frame 2 fixedly connected to the top of the mounting plate 1, and multiple positioning holes 7 on the outer side of the mounting plate 1. The multiple positioning holes 7 are evenly distributed in a ring about the central axis of the mounting plate 1. The device can be placed on a horizontal surface through the mounting plate 1. By using external bolts and positioning holes 7 in conjunction, the mounting plate 1 can be fixed to the external horizontal surface, thus completing the installation of the device.

[0028] In this embodiment, a central frame 14 is fixedly connected to the inner side of the through hole of the mounting plate 1, and a central rod 15 is fixedly connected to the top center of the central frame 14. The central axis of the central rod 15 coincides with the central axis of the circular frame 2. The central frame 14 and the mounting plate 1 form an integrated structure. The cement rod can be placed using the central frame 14. The bottom of the cement rod is usually a hollow structure, so that the central rod 15 can enter the interior of the cement rod, which is convenient for placing and positioning the cement.

[0029] In this embodiment, multiple side plates 3 are fixedly connected to the outer side of the circular frame 2. The multiple side plates 3 are evenly distributed in a ring about the central axis of the circular frame 2. A first threaded rod 4 is threadedly connected to the side plate 3. A pressure plate 5 is rotatably connected to the end of the first threaded rod 4. A telescopic rod 6 is fixedly connected to the bottom end of the pressure plate 5. One end of the telescopic rod 6 is fixedly connected to the inner wall of the circular frame 2. The central axis of the first threaded rod 4 coincides with the horizontal center line of the side plate 3. The end of the first threaded rod 4 has a "plum blossom" structure. The central axis of the mounting plate 1 coincides with the central axis of the circular frame 2. By rotating the first threaded rod 4 on the side plate 3 and using the telescopic rod 6, the pressure plate 5 can be moved closer to the cement pole in the center of the circular frame 2, so that the pressure plate 5 presses against cement poles of different diameters, thereby clamping cement poles of different diameters, enhancing the stability of the bottom of the cement pole, and also making the device applicable to cement poles of different diameters, improving the applicability of the device.

[0030] In this embodiment, an arc-shaped groove is provided on the side of the pressure plate 5 near the center of the circular frame 2, and an arc-shaped rubber pad 8 is fixedly connected to the arc-shaped groove. One side of the arc-shaped rubber pad 8 is in contact with the inner wall of the arc-shaped groove.

[0031] In this embodiment, a threaded cylinder 9 is provided on one side of the top of the pressure plate 5. The threaded cylinder 9 and the pressure plate 5 form an integrated structure. The top of the threaded cylinder 9 is threadedly connected to a second threaded rod 10. The top of the second threaded rod 10 is fixedly connected to a pressure block 11. By rotating the second threaded rod 10 in conjunction with the use of the threaded cylinder 9, the height of the pressure block 11 can be adjusted, thereby facilitating the change of the pressure position of the pressure block 11. This allows the device to adjust the support point of the pressure block 11 on the cement pole according to the length of the cement pole. The vertical center line of the pressure block 11 coincides with the central axis of the second threaded rod 10. Multiple rubber strips 12 are provided on the outer side of the pressure block 11. The multiple rubber strips 12 are evenly distributed in a ring about the vertical center line of the pressure block 11. The rubber strips 12 and the pressure block 11 form an integrated structure. The arc-shaped rubber pad 8 and the rubber strips 12 can prevent the pressure block 11 and the pressure plate 5 from causing wear on the cement pole.

[0032] In this embodiment, multiple reinforcing strips 13 are provided on the outer side of the circular frame 2. The multiple reinforcing strips 13 are evenly distributed in a ring about the central axis of the circular frame 2. The reinforcing strips 13 and the circular frame 2 form an integrated structure. The setting of the reinforcing strips 13 can enhance the strength of the circular frame 2, thereby making the circular frame 2 less prone to deformation.

[0033] Working principle: When using this device, the device can first be placed on a horizontal surface using the mounting plate 1. The mounting plate 1 can be fixed to the external horizontal surface using the external bolts and positioning holes 7, thus completing the installation of the device. The cement rod can be placed using the central frame 14. The bottom of the cement rod is usually hollow, allowing the central rod 15 to enter the interior of the cement rod, which facilitates the placement and positioning of the cement.

[0034] By rotating the first threaded rod 4 on the side plate 3 and using the telescopic rod 6, the pressure plate 5 can be moved closer to the cement rod at the center of the circular frame 2, so that the pressure plate 5 presses against cement rods of different diameters, thereby clamping the cement rods of different diameters, enhancing the stability of the bottom of the cement rod, and also making the device applicable to cement rods of different diameters, thus improving the applicability of the device.

[0035] Rotating the second threaded rod 10, in conjunction with the threaded cylinder 9, allows adjustment of the height of the pressure block 11, thus facilitating changes in the pressure position of the pressure block 11. This allows the device to adjust the support point of the pressure block 11 on the cement rod according to its length. The arc-shaped rubber pad 8 and rubber strip 12 prevent the pressure block 11 and pressure plate 5 from causing wear on the cement rod. The reinforcing strip 13 enhances the strength of the circular frame 2, making it less prone to deformation.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
