Description

Technical Field

[0001] This utility model relates to a solar thermal power generation steel-concrete tower, specifically a precast concrete tower segment mold. Background Technology

[0002] Wind energy is a clean and renewable energy source, and wind power generation is the main form of wind energy utilization. It is also one of the most technologically mature, scalable, and commercially viable renewable energy sources besides hydropower. With the continuous increase in tower height, reinforced concrete towers have emerged. The upper part of a reinforced concrete tower consists of steel sections, while the lower part consists of concrete sections. These sections are connected by a transition section (or "flange"), and the concrete sections are fixed to a concrete foundation. The tower shape typically adopts a tapered, gradually changing form, where the tower diameter changes uniformly from bottom to top. Compared to other forms, the tapered, gradually changing tower structure has the most reasonable overall stress distribution, maximizing the arch effect of the ring, eliminating significant stress concentration problems, ensuring structural safety and reliability, and possessing universal applicability. To improve on-site installation efficiency and ensure the quality of the concrete sections, the lower concrete sections are usually constructed by splicing precast concrete segments.

[0003] The conical, gradually decreasing precast concrete tower section is composed of multiple individual tower sections connected together. The specific number of tower sections can be determined based on the height combination of the steel tower section and the concrete tower section. Each individual tower section is usually composed of 2 to 4 precast tube segments. However, because the diameter of the conical tower gradually decreases from bottom to top, the diameter of each tower section is different, resulting in different molds for different tower sections. The variety of steel molds leads to a high overall mold manufacturing cost.

[0004] Currently, reinforced concrete towers have become the preferred solution for high towers. The amortization cost of precast concrete tower section molds has become one of the main factors affecting the cost of reinforced concrete towers, thus affecting their widespread use. Therefore, how to reduce the cost of precast concrete tower section molds has become an urgent problem to be solved. Utility Model Content

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0033] like Figures 1-4 As shown, this utility model provides a precast concrete tower segment mold. The mold consists of an upper fixing plate 1, a lower fixing plate 2, an inner vertical strip steel plate 3, an outer vertical strip steel plate 4, a sealing cloth 11, an inner end vertical strip steel plate 6, and a vertical end closing steel plate 5. The upper fixing plate 1 and the lower fixing plate 2 are respectively provided with a fixing groove 8, an inner end vertical strip steel plate fixing groove 10, and a vertical end closing steel plate fixing groove 9. The upper fixing plate 1 and the lower fixing plate 2 are connected by the inner vertical strip steel plate 3, the outer vertical strip steel plate 4, the inner end vertical strip steel plate 6, and the vertical end closing steel plate 5.

[0034] like Figure 5The upper fixing plate 1 shown is used to fix the vertical steel plate and close the top surface of the mold. The upper fixing plate 1 is provided with a concrete pouring hole 7 for pouring concrete. The upper fixing plate 1 is provided with a fixing groove 8. The cross-sectional area of ​​the fixing groove 8 is larger than the cross-sectional area of ​​the inner vertical strip steel plate 1 and the outer vertical strip steel plate 2. That is, the size of the fixing groove is slightly larger than the cross-sectional size of the vertical steel plate, so that the vertical strip steel plate can be inserted into the fixing groove. The slope inside the fixing groove is the same as the slope of the segment. The fixing groove is used to fix the inner and outer vertical strip steel plates and the vertical end closing steel plate.

[0035] like Figure 6 The lower fixing plate 2 shown is used to fix the vertical steel plate and close the bottom surface of the mold. Bolt holes 13 are opened on the lower fixing plate 2 as needed to fix the lower fixing plate to the installation platform. A fixing groove 13 is provided on the lower fixing plate. The cross-sectional area of ​​the fixing groove is larger than the cross-sectional area of ​​the inner vertical strip steel plate and the outer vertical strip steel plate. That is, the size of the fixing groove is slightly larger than the cross-sectional size of the vertical steel plate. The slope inside the fixing groove is the same as the slope of the segment. It is used to fix the inner vertical strip steel plate 3, the outer vertical strip steel plate 4 and the vertical end closing steel plate 5.

[0036] like Figure 10 , Figure 11 The inner vertical strip steel plate 3 and the outer vertical strip steel plate 4 shown are both equipped with positioning plates 14. The inner vertical strip steel plate 3 and the outer vertical strip steel plate 4 can be inserted into the fixing grooves in the upper fixing plate 1 and the lower fixing plate 2 to form the inner and outer support skeleton of the mold.

[0037] like Figure 7 As shown, the inner end vertical strip steel plate fixing groove 10 is located on one side inside the vertical end closed steel plate fixing groove 9, and there is a gap between the inner end vertical strip steel plate fixing groove 10 and the vertical end closed steel plate fixing groove 9.

[0038] like Figure 9 The vertical strip steel plate 3 at the inner end shown: a fixing pin 15 is provided on the vertical strip steel plate at the inner end, which is used to form the inner support skeleton of the mold, and also to fix the high elastic PVC sealing cloth inside the mold.

[0039] like Figure 8 The vertical end sealing steel plate 5 shown: a fixing pin 15 is provided on the vertical end sealing steel plate 5 to seal the side of the mold; a fixing pin 15 is provided on the steel plate on the splicing surface of the adjacent precast concrete pipe segment to fix the outer high elastic PVC sealing cloth; the length of the inner plate of the vertical end sealing steel plate should not exceed the position of the air hole buckle to ensure that it does not interfere with the air hole buckle of the inner sealing cloth.

[0040] like Figure 12The sealing cloth shown is made of high-elasticity PVC and is used to seal the inside and outside of the mold to prevent slurry leakage. The sealing cloth on the outside of the mold is located on the outside of the entire mold and is fixed to the fixing pin of the vertical end sealing steel plate by the air hole buckle 16 of the sealing cloth.

[0041] The sealing cloth inside the mold is located inside the entire mold. The sealing cloth is arranged inside the mold and passes through the gap between the vertical end sealing steel plate 5 and the inner end vertical strip steel plate 6, bypassing the inner end vertical strip steel plate and fixed to the fixing pin 15 of the inner end vertical strip steel plate.

[0042] The sealing cloth is secured to the vertical end sealing steel plate and the inner end vertical strip steel plate by fixing pins with claw-shaped tarpaulin eye buckles at evenly spaced holes and sealing edges. The installed sealing cloth is in a taut state.

[0043] Strong magnetic buckle 12: Used to fix the outer sealing cloth of the mold to the vertical steel plate of the mold.

[0044] The following points should be noted regarding the precast concrete tower segment mold provided by this utility model.

[0045] (1) The inner vertical strip steel plate 3, the outer vertical strip steel plate 4, the vertical end closed steel plate 5, the inner end vertical strip steel plate 6, the upper fixed plate 1 and the lower fixed plate 2 should all have a certain thickness to ensure that the steel plate does not deform significantly during use, especially after concrete is poured.

[0046] (2) The height of the inner vertical strip steel plate 3, the outer vertical strip steel plate 4 and the vertical end closing steel plate 5 is determined according to the height of each section of the tower, so as to make the height of multiple tower sections consistent, so that the steel plates can be recycled.

[0047] (4) The spacing of the vertical strip steel plates in each tower section, as well as the size, quantity and distribution of the magnetic buckles, should be determined in combination with the selected sealing cloth material to ensure that there is no obvious bulging or deformation of the PVC sealing cloth between the two vertical strip steel plates after the concrete is poured.

[0048] The installation steps of the precast concrete tower segment mold provided by this utility model are as follows.

[0049] (1) Before assembling the mold or pouring concrete, apply lubricating oil to all surfaces of the mold that come into contact with the concrete to facilitate the subsequent removal of the mold.

[0050] (2) Fix the lower fixing plate to the ground mounting platform with bolts.

[0051] (3) Insert the inner vertical strip steel plate and the outer vertical strip steel plate into the fixing groove on the lower fixing plate for fixing until the depth of the positioning plate is reached.

[0052] (4) Fix the two ends of the inner high elastic PVC sealing cloth to the fixing pins of the vertical strip steel plate at the inner end through the air hole buckle. The inner sealing cloth of the mold is located inside the entire mold. After fixing, the sealing cloth is in a tensile state and is not easy to deform.

[0053] (5) Insert the vertical closed steel plates at both ends into the fixing grooves on the lower fixing plate for fixing until the depth of the positioning plate is reached.

[0054] (6) Insert the upper fixing plate into the vertical strip steel plate and the vertical closed steel plates at both ends for fixing until the depth of the positioning plate is reached.

[0055] (7) Fix both ends of the outer high elastic PVC sealing cloth to the fixing pins of the vertical end sealing steel plate through the air hole buckle; after fixing, the sealing cloth is in a tensile state and is not easy to deform.

[0056] (8) Arrange strong magnetic buckles evenly on the outer PVC sealing cloth to fix the outer sealing cloth to the outer vertical steel plate to prevent it from bulging and deforming too much after the concrete is poured.

[0057] (9) Finally, the mold is transported to the concrete pouring station to pour concrete. After pouring, the seven reserved grouting holes on the upper fixing plate are manually smoothed to ensure the smoothness and flatness of the finished surface. Then the precast concrete components are transported to the curing area for curing. After the concrete curing is completed, the mold is removed and the mold can be recycled.

[0058] For conical tower sections, the mold diameter described in this patent can be adjusted according to the specific needs of each tower section. Its vertical strip steel plates and magnetic buckles can be used for any tower section of the same height, achieving recycling. The upper and lower fixing plates can be configured with multiple rows of fixing slots on a larger steel plate, depending on the actual situation of multiple tower sections sharing the fixing plate, to fix the vertical steel plates of multiple tower section molds, achieving steel savings. The spacing between the vertical strip steel plates in the mold is sealed with high-elasticity PVC sealing cloth, reducing the steel consumption of each tower section mold and saving mold costs. Furthermore, with proper design, the PVC cloth can also be used for multiple tower sections at different elevations. The precast concrete segments prepared using this patent mold have cross-sections that are not ideally circular, but rather polygonal, approximating a circle. Their stress performance is very close to that of an ideal conical tower, making them a viable alternative to an ideal conical tower.

[0059] Therefore, compared to the traditional conical tower section which requires a dedicated steel mold for each section, this patented mold can reuse most of its components, greatly reducing the overall consumption of mold steel and thus achieving the beneficial effect of saving mold costs.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
