Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and more specifically, to a precast concrete slab expander for use in construction projects. Background Technology

[0002] The precast concrete slab fine-tuning expander for building construction is a device used for the installation, connection, fine-tuning, and expansion of precast concrete slabs in building construction. Its main function is to fill the gaps between precast concrete slabs with material to achieve horizontal or vertical fine-tuning and expansion between the slabs. However, commonly used precast concrete slab expanders have the function of measuring the vertical position of the precast concrete slabs during use, but lack fine-tuning function, which narrows the scope of application and reduces the convenience of use.

[0003] For example, CN221736562U discloses a precast concrete slab fine-tuning expander for building engineering, which includes a main body, a receiving rod rotatably connected inside the main body, and through holes on the front and rear surfaces of the bottom of the receiving rod; and a threaded plate, which is arranged around the upper end of the receiving rod.

[0004] As can be seen from the above-mentioned publicly available scheme, the precast concrete slab fine-tuning expander can only measure the vertical position of the precast concrete slab through the support plate, rope column plumb bob and scale block, and cannot fine-tune it. At the same time, it cannot measure and fine-tune the horizontal position of the precast concrete slab, thus narrowing its applicable scope and causing inconvenience to the fine-tuning and expansion of the precast concrete slab.

In addition, the set horizontal adjustment plate and vertical adjustment column can measure and fine-tune the horizontal position of the horizontally set concrete precast slab, which increases the applicability of the expander.

[0008] Furthermore, the storage box has a groove on its side, and a locking block is fixedly connected to the inner wall of the groove. The locking block is made of rubber, and the surface of the locking block contacts and presses against the surface of the movable rod, so that the locking block can quickly fix the storage position of the diagonal rod.

[0009] Furthermore, one end of the horizontal adjustment plate is provided with a guide groove, the inner wall of the guide groove is slidably connected to the surface of the guide rod, and the cross-sectional shape of the guide groove and the guide rod is rectangular, which ensures the movement stability of the vertical adjustment plate.

[0010] Furthermore, one end of the support column is provided with a storage groove, the inner wall of which is connected to a pin hole, and the cross-sectional shape of the storage groove is polygonal, which can adjust the total length of the support column and the adjustment column.

[0011] Furthermore, the surface of the adjusting column is provided with adjusting holes, which are evenly distributed, and positioning pins are inserted into the inner walls of the adjusting holes and pin holes.

[0025] Example 1

[0026] Please see Figure 1-5A precast concrete slab expander for construction engineering includes an expander base 1, with anti-slip nails at the bottom. A support column 2 is detachably connected to the surface of the expander base 1, and an adjusting column 4 is slidably sleeved at one end of the support column 2. The expander base 1 is characterized by having a storage box 22 fixedly connected to its side, with a diagonal rod 3 rotatably connected to its inner wall via a pivot 23. One end of the diagonal rod 3 has a threaded hole, and the surface of a movable rod 31 has external threads, allowing the movable rod 31 to extend and retract to adjust the diagonal support length for easy use and storage. The movable rod 31 is extendably adjustable at one end of the diagonal rod 3, and one end of the movable rod 31 has a sharp point. The diagonal rod 3 and the movable rod 31... Used to support the expander and ensure its stability, an expansion seat 5 is fixedly connected to one end of the adjusting column 4. A vertical adjusting column 51 is provided at one end of the expansion seat 5. The vertical adjusting column 51 is a hydraulic telescopic rod. A horizontal adjusting column 52 is provided on the side of the expansion seat 5. The horizontal adjusting column 52 is a hydraulic telescopic rod. A horizontal adjusting plate 6 is fixedly installed at one end of the vertical adjusting column 51. The included angle between the horizontal adjusting plate 6 and the vertical adjusting plate 7 is 90 degrees. A vertical adjusting plate 7 is fixedly connected to one end of the horizontal adjusting column 52. A guide rod 71 is fixedly connected to the side of the vertical adjusting plate 7. A telescopic column 63 is fixedly connected to one end of the guide rod 71. The telescopic column 63 is a hydraulic telescopic rod. This is existing technology.

[0027] The storage box 22 has a groove on its side, and a locking block 24 is fixedly connected to the inner wall of the groove. The locking block 24 is made of rubber. The surface of the locking block 24 contacts and presses against the surface of the movable rod 31. The locking block 24 can quickly fix the storage position of the inclined rod 3. One end of the horizontal adjustment plate 6 is provided with a guide groove 61. The inner wall of the guide groove 61 is slidably connected to the surface of the guide rod 71. The cross-sectional shape of the guide groove 61 and the guide rod 71 is rectangular, which ensures the stability of the vertical adjustment plate 7. One end of the guide groove 61 is connected to the installation groove 62, which facilitates the installation and storage of the telescopic column 63.

[0028] One end of the support column 2 is provided with a storage groove 21. The inner wall of the storage groove 21 is connected to a pin hole 25.

The inner walls of the adjustment holes 41 and the pin hole 25 are connected to positioning pins 26.

[0029] When adjusting the vertical position of a precast concrete slab in construction engineering, the expansion device first contacts the surface of the vertical adjustment plate 7 with the upper surface of the vertically positioned precast concrete slab. When a gap remains between the surface of the precast slab and the surface of the vertical adjustment plate 7, the horizontal adjustment column 52 and the telescopic column 63 are activated. This causes the vertical adjustment plate 7 to press against the upper side of the precast concrete slab, ensuring the slab moves and fully contacts the surface of the vertical adjustment plate 7, placing the precast slab in a vertical position. To adjust the horizontal position of the precast concrete slab, the surface of the horizontal adjustment plate 6 is then brought into contact with water. The bottom of one end of the horizontally set precast concrete slab is attached. If there is a gap, the vertical adjustment column 51 is activated to make the horizontally set precast concrete slab horizontal. The vertical adjustment plate 7 and the expansion seat 5 can be used to quickly measure the vertical position of the precast concrete slab. At the same time, the horizontal adjustment column 52 and the telescopic column 63 can be used to fine-tune the vertical position of the precast concrete slab, which greatly improves the convenience of use. Furthermore, the horizontal adjustment plate 6 and the vertical adjustment column 51 can be used to measure and fine-tune the horizontal position of the horizontally set precast concrete slab, which increases the applicability of the expander.
