Description

Technical Field

[0001] This utility model relates to the field of new energy engineering construction technology, specifically to a fixing device for pre-embedded steel in micropiles. Background Technology

[0002] The embedded parts for the support structure of centralized photovoltaic power generation plants are generally steel pipes, anchor bolts, etc., which are small in size and can usually be installed and adjusted manually.

[0003] However, in recent years, design units have gradually changed their design concepts for micropiles. In order to improve the overall stability of photovoltaic brackets, they have begun to use steel-type direct-buried piles as embedded parts and as the entire column of the bracket. However, the steel bracket column itself is heavy, generally exceeding 40 kilograms. With the added pre-embedded length, the total weight generally exceeds 50 kilograms. If machinery is not used, manual operation is quite difficult.

[0004] Furthermore, if mechanical equipment is used for temporary fixing or correction of the entire support structure, it is not economical from the perspective of construction cost, given the large number of supports in the photovoltaic power generation area and the low utilization rate and high fuel cost of the embedded parts for mechanical fixing or correction.

[0005] Therefore, a high-efficiency, low-cost mechanical device is needed to replace engineering machinery for the temporary fixing of photovoltaic support steel columns, so as to reduce construction costs while ensuring construction quality. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a fixing device for pre-embedded steel in micropiles that reduces labor intensity, improves construction efficiency, reduces the use of engineering machinery, and lowers construction costs.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a fixing device for pre-embedded steel in micro piles, including an adjustable support rod, an anchoring base plate, and an adjustable steel clamp;

[0008] The adjustable steel clamp is a clamp structure whose inner shape is adapted to the shape of the pre-embedded steel. The inner size of the adjustable steel clamp is adjustable and is used to hug and fix the pre-embedded steel.

[0009] The upper end of the adjustable support rod is hinged to the four sides of the adjustable steel clamp, and the bottom end of the adjustable support rod is installed with the anchoring base plate. The length of the adjustable support rod is adjustable.

[0010] The anchoring base is used to fix it to the ground.

[0011] Preferably, the adjustable steel clamp includes a clamp frame and fastening bolts. The clamp frame is formed by splicing two symmetrically arranged U-shaped frames. The two U-shaped frames are locked and fixed together by fastening bolts, and the tightness can be adjusted.

[0012] Preferably, the splicing ends of the two U-shaped frames are provided with splicing parts, and the splicing parts are provided with bolt mounting holes. The fastening bolts are used to splice the two U-shaped frames into one piece through the bolt mounting holes.

[0013] Preferably, a rubber pad is installed at the inner corner of the clamp frame.

[0014] Preferably, four ear plates are provided at the four corners of the clamp frame, and mounting holes are provided on the ear plates. The top end of the adjustable support rod is hinged to the mounting holes.

[0015] Preferably, the adjustable support rod includes an upper support rod, a lower support rod, and a spiral adjusting sleeve structure. The spiral adjusting sleeve structure includes a sleeve, an upper support rod ball, a ball top spring, an assembly block, and a screw section.

[0016] The upper support rod ball, ball top spring and assembly block are installed in the upper end tube of the sleeve. The upper end tube is provided with a sleeve rotation sliding track corresponding to the upper support rod ball so that the upper support rod can rotate freely relative to the sleeve.

[0017] The lower end of the sleeve is the screw part, and the upper end of the lower support rod is set as the inner threaded cylinder of the lower support rod. The screw part of the sleeve is threadedly engaged with the inner threaded cylinder of the lower support rod.

[0018] Preferably, the anchoring base plate includes a base plate, anchor holes, and base plate lugs. The bottom end of the adjustable support rod is hinged to the base plate lugs, and the base plate is fixed to the ground through ground nails and anchor holes.

[0020] Preferably, the adjustable steel clamp is a rectangular clamp.

[0021] Preferably, the adjustable support rod and the adjustable steel clamp are made of aluminum alloy.

[0022] This utility model has substantial features and advancements compared to existing technologies. Specifically, it effectively replaces traditional engineering machinery by using a simple mechanical support structure to temporarily fix the pre-embedded steel. Due to the long waiting period for pre-embedding and concrete pouring, this device consumes no energy during the waiting period compared to engineering machinery. It can handle multiple processes simultaneously in parallel, and its manufacturing difficulty and cost are relatively low. It also reduces the time occupied by engineering machinery, thereby reducing the labor intensity of manual operations, improving construction efficiency, reducing the use of engineering equipment, and lowering construction costs.

[0023] Because of its adjustable design, the requirements for ground flatness are reduced, ensuring the installation accuracy of the embedded steel and its stability before and after concrete pouring.

Detailed Implementation

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0032] like Figures 1-5 As shown, a fixing device for pre-embedded steel in micropiles includes an adjustable support rod 2, an anchoring base plate 4, and an adjustable steel clamp 1.

[0033] In this embodiment, to ensure robustness and portability, facilitate movement and maintenance, and meet the requirements of convenient turnover, the adjustable support rod 2 and the adjustable steel clamp 1 are made of aluminum alloy.

[0034] The adjustable steel clamp 1 is a clamp structure whose inner shape is adapted to the shape of the embedded steel. The inner size of the adjustable steel clamp 1 is adjustable and is used to hug and fix the embedded steel 5. In this embodiment, the adjustable steel clamp is a rectangular clamp.

[0035] Specifically, in this embodiment, the adjustable steel clamp 1 includes a clamp frame 101 and fastening bolts 103. The clamp frame 101 is formed by splicing two symmetrically arranged U-shaped frames. The splicing ends of the two U-shaped frames are provided with splicing parts, and the splicing parts are provided with bolt mounting holes. The fastening bolts 103 splice the two U-shaped frames into one piece through the bolt mounting holes, and lock and fix them and adjust the tightness through the fastening bolts 103.

[0036] To prevent wear on the embedded steel 5, rubber pads 102 are installed at the inner corners of the clamp frame 101.

[0037] Four ear plates 104 are provided at the four corners of the clamp frame 101. The ear plates 104 are provided with mounting holes. The top end of the adjustable support rod 2 is hinged to the mounting hole.

[0038] The length of the adjustable support rod 2 is adjustable. Specifically, in this embodiment, the adjustable support rod 2 includes an upper support rod, a lower support rod, and a spiral adjusting sleeve structure 3. The spiral adjusting sleeve structure 3 includes a sleeve 301, an upper support rod ball 303, a ball top spring 304, an assembly block 305, and a screw part 306.

[0039] The upper support rod ball 303, ball top spring 304, and assembly block 305 are installed in the upper end tube of the sleeve 301. The assembly block 305 is used to tighten the tube and provide installation space for the upper support rod ball 303 and ball top spring 304. A sleeve rotation sliding track 302 is provided in the upper end tube corresponding to the upper support rod ball 303, which is used to cooperate with the upper support rod ball 303 to roll in the track so that the upper support rod can rotate freely relative to the sleeve 301.

[0040] The lower end of the sleeve 301 is the screw part 306, and the upper end of the lower support rod is set as the lower support rod inner threaded cylinder 307. The screw part 306 of the sleeve is threadedly engaged with the lower support rod inner threaded cylinder 307. By screwing in or loosening, the overall length of the adjustable support rod 2 can be adjusted.

[0041] For ease of adjustment, the sleeve 301 is designed with a polygonal outline to accommodate adjustment tools, such as a hexagonal outline, which can be used with conventional tools such as wrenches.

[0042] The bottom end of the adjustable support rod 2 is fitted with the anchoring base 4, which is used to fix the rod to the ground. Specifically, in this embodiment, the anchoring base 4 includes a base plate, an anchor hole 401, and a base plate ear plate 402. The bottom end of the adjustable support rod 2 is hinged to the base plate ear plate 402, and the base plate is fixed to the ground by ground nails and the anchor hole 401.

[0043] In use, first place the device at a suitable position above the pre-embedded location of the steel profile 5. Then, tighten the clamps with bolts 103 to fix it to the steel profile 5. Support the device and the pre-embedded steel profile using the adjustable support rods 2 around the device. Then, anchor the anchoring base 4 of the adjustable support rod 2 using wooden wedges or steel nails. Next, adjust the length of the adjustable support rod 2 using the spiral adjusting sleeve 3 (the screw can rotate independently). When the steel profile 5 is adjusted to a vertical position with the help of a vertical ruler, the steel profile is fixed. Figure 5 As shown in the attached figure, the location of the cast-in-place pile template or the formed pile head 6 is illustrated.

[0044] Then, the equipment is used to pour concrete into the pre-embedded area of ​​the steel section. After the concrete has set, the equipment is removed and moved to the next area.

[0045] Because the length of the adjustable support rod 2 is adjustable, it can adapt to uneven and pitted terrain. As it is a temporary fixing device, it is highly flexible and can meet the needs of various types of embedded parts. Furthermore, since the entire device is an assembly, parts can be replaced when damaged, making maintenance convenient.

[0046] The main function of this device is to provide temporary fixation during the pouring of pre-embedded steel sections, preventing them from sinking, tilting, or moving before the concrete has reached its full strength.

[0047] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
