Description

Technical Field

[0001] This utility model relates to the field of pile cap construction technology, specifically to a photothermal field pile cap and bolt positioning kit. Background Technology

[0002] Currently, solar thermal power (CSP) projects are increasingly common in power plant construction. The efficiency of a CSP plant mainly depends on the solar thermal efficiency of the mirrors and collectors. High solar thermal efficiency ensures high lava temperatures, which in turn lead to higher power generation efficiency. Therefore, the installation accuracy of the mirrors and supports in a CSP plant project is of paramount importance. A 4MW unit typically has approximately 9500 mirrors, each requiring a pile foundation, and each pile foundation has four anchor bolts to secure the mirror and support. Based on this calculation, 9500 * 4 = 38000 pile cap bolts are needed for this type of unit. Therefore, pile cap installation and the installation of pre-embedded pile cap bolts are characterized by high precision and a large workload.

[0003] Based on the above characteristics, and considering that the installation accuracy of the mirrors and supports determines the power generation efficiency of the solar thermal power project, the construction of the pile caps and the precision requirements for the pre-embedded bolts in the pile caps are even higher, since the mirror supports are installed on the pile caps. To ensure this, the installation accuracy of all 38,000 bolts on the pile caps of the entire unit must be controlled within 5mm, while simultaneously improving work efficiency, reducing procedures, reducing labor costs, and controlling the overall quality of the pile cap bolts.

[0031] See Figures 1-4The present invention relates to a photothermal field pile cap and bolt positioning kit, comprising a pile cap concrete template 1 and an anchor bolt support frame erected in the middle of the pile cap concrete template 1.

[0032] The pile cap concrete formwork 1 comprises two semi-circular templates. Each semi-circular template includes a semi-circular base plate 11 and a semi-circular vertical plate 12. The vertical plate 12 is vertically fixed to the inner edge of the base plate 11. Connecting plates 13 are provided at both ends of the vertical plate 12, with connecting holes in the middle of the connecting plates 13. The two semi-circular templates are fitted together, and bolts are passed through the two fitted connecting holes to fix the two semi-circular templates, thus forming the pile cap concrete formwork 1. The pile cap concrete formwork 1 can be repeatedly disassembled and reused.

[0033] The base plate 11 of this utility model has two fixing holes 14, which are used to reinforce the installation when installing a mirror. The diameter of the fixing holes 14 is 10-25mm. Both the base plate 11 and the vertical plate 12 are made of 2mm thick carbon steel plates, and the height of the vertical plate 12 is 40cm.

[0034] The anchor bolt support frame includes a pile cap bolt positioning plate 2, a pile cap bolt fixing plate 3 located below the pile cap bolt positioning plate 2, and anchor bolts 4 passing through the pile cap bolt positioning plate 2 and the pile cap bolt fixing plate 3 in sequence.

[0035] The pile cap bolt positioning plate 2 is a square plate with a first central circular hole 22 at its center, the diameter of which is 6mm. Two first square slots 21 are formed along the length of the pile cap bolt positioning plate 2, symmetrically arranged around the first central circular hole 22. Four first anchor bolt holes, each 36mm in diameter, are evenly distributed along the four corners of the pile cap bolt positioning plate 2 for the anchor bolts 4 to pass through.

[0036] The pile cap bolt fixing plate 3 is a square plate with a second central circular hole 32 at its center. The diameter of the second central circular hole 32 is 6mm. Two second square slots 31 are formed along the length of the pile cap bolt fixing plate 3, and the two second square slots 31 are symmetrically arranged with the second central circular hole 32 as the center. Four second anchor bolt holes are provided on the pile cap bolt fixing plate 3, with a diameter of 36mm. The four second anchor bolt holes are evenly distributed along the four corners of the pile cap bolt fixing plate 3 for the anchor bolts 4 to pass through.

[0037] Both the pile cap bolt positioning plate 2 and the pile cap bolt fixing plate 3 of this utility model are made of 4mm thick carbon steel plates.

[0038] This utility model has four anchor bolts 4, which pass sequentially through the corresponding second anchor bolt holes and first anchor bolt holes.

Then, place the first set of four second nuts 42 in the required positions of the four anchor bolts 4. Next, insert four anchor bolts 4 into the four second anchor bolt holes of the pile cap bolt fixing plate 3. Place the pile cap bolt fixing plate 3 on the upper part of the pile cap reinforcement cage, and then place the second set of four second nuts 42 on the four anchor bolts 4. At this time, the pile cap bolts are positioned according to latitude, longitude, and height. After positioning, tighten the two sets of second nuts 42 and weld them to the anchor bolts 4. In this way, the anchor bolts 4, together with the pile cap bolt fixing plate 3, are irremovably fixed to the pile cap reinforcement cage. Next, place the first set of four third nuts 43 onto the four anchor bolts 4 respectively. Then, insert the four anchor bolts 4 into the four first anchor bolt holes of the pile cap bolt positioning plate 2 respectively. Place the second set of four third nuts 43 onto the four anchor bolts 4 respectively. At this point, the latitude and height of the anchor bolts 4 need to be checked again. After positioning, tighten the third nuts 43. Finally, with the first central circular hole 22 of the pile cap bolt positioning plate 2 as the center, the pile cap concrete template 1 is surrounded by this center. The pile cap concrete template 1 is mainly used for shaping after the pile cap is poured. The bottom surface of the bottom plate 11 of the pile cap concrete template 1 is placed against the ground. Concrete is poured inside and below the vertical plate 12 until it is flush with the height of the vertical plate 12. This completes the pile cap construction and the pre-embedded installation of the anchor bolts.

[0041] This utility model's positioning kit eliminates the need for repeated positioning and adjustments by personnel. This tool improves work efficiency and process quality, ensures the installation accuracy of pile caps and anchor bolts, and increases the first-time acceptance rate.
