Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module installation, and in particular to a mold for pouring concrete piers. Background Art

[0002] As the new development concept of carbon peak and carbon neutrality continues to strengthen, new energy represented by photovoltaic power generation is the main development direction for achieving the "dual carbon" goal and green transformation, and photovoltaic power generation is indispensable for the concrete pier installed at the bottom of the photovoltaic module. The concrete pier is mainly made of a pier mold. The concrete pier mold of the photovoltaic module is also called the photovoltaic base mold and the photovoltaic cement pier mold. It is a small prefabricated block mold. The common length and width dimensions are 200 mm, 300 mm, 400 mm, 500 mm, etc., usually a rectangular structure. The main function of the concrete pier is to provide a support point for installing photovoltaic modules on the roof or some sites that can fully collect solar energy. The concrete pier used for photovoltaic modules has high requirements for the accuracy of the pier mold because it is necessary to make the inclination angle of the sunlight and the photovoltaic module panel consistent after the photovoltaic module is installed.

[0003] The mold for a concrete pier is usually composed of multiple independent steel plates. When in use, workers need to first find steel plates of appropriate specifications one by one from the template stacking area according to the size requirements of the pier, and then surround these steel plates into a rectangular structure with an open top, and the adjacent steel plates are fixed with multiple bolts. In this way, a mold required for pouring concrete piers can be formed. The mold of this structure is very troublesome to assemble, and workers need to sort and collect it after disassembly, which is time-consuming and labor-intensive. Utility Model Content

[0010] Furthermore, the lengths of the two limiting clamps above two opposite edges of the cuboid structure composed of the four rectangular side templates are greater than the lengths of the other two limiting clamps.

[0011] Furthermore, the free end of one of the split bottom plates is a positive step-shaped interface, and the free end of the other split bottom plate is a matching inverted step-shaped interface; when the two split bottom plates are rotated toward each other to a horizontal state, the free ends of the two split bottom plates can be overlapped together.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0023] like Figure 1 and Figure 3 As shown, a mold for pouring concrete pier disclosed in the present application includes four rectangular side templates 1 with the same structure, the four rectangular side templates 1 are circumferentially surrounded to form a rectangular parallelepiped structure that is connected from top to bottom, and they are movably connected by hinges; a limiting component 2 is provided at the upper end of the four rectangular side templates 1, and the limiting component 2 can limit the position of the four rectangular side templates 1, so that they are difficult to shake;

[0024] Two relatively positioned rectangular side templates 1 are each movably connected to a split bottom plate 3 through a hinge, and the sizes of the two split bottom plates 3 are sufficient to cover the lower port of the rectangular structure formed by the four rectangular side templates 1 when the two split bottom plates 3 are rotated toward each other to a horizontal state.

[0025] In the above embodiments, the concrete base pier usually used to install photovoltaic modules is a rectangular structure, and the mold used to cast the concrete base pier is generally a rectangular box with an open upper end. The four rectangular templates of the present application are connected end to end in sequence through hinges, and the angles between them are all right angles. These four rectangular side templates 1 are equivalent to the four side walls of the traditional rectangular box mold. When the split bottom plates 3 arranged below two opposite rectangular side templates 1 rotate toward each other (rotating toward each other means that the two split bottom plates 3 rotate toward each other around the axis of the hinge shaft at their respective ends) to a horizontal state, the two split bottom plates 3 can jointly form a flat plate to block the bottom opening of the rectangular structure surrounded by the four rectangular side templates 1. The flat plate jointly formed by the two split bottom plates 3 is equivalent to the bottom mold of the rectangular box mold.

[0026] When the mold of the present application is in use, the worker can first place the two split bottom plates 3 flat on the ground and bring their free ends close to each other, and then expand the four rectangular side templates 1 above the two split bottom plates 3 to form a rectangular structure. The lower port of the rectangular structure is blocked by the two split bottom plates 3. Therefore, the rectangular structure at this time forms a rectangular mold with only an open upper end. Since each rectangular side template 1 is connected by a hinge, the four rectangular side templates 1 at this time are similar to a four-bar linkage. If there is no restriction, they may be deformed at the slightest force. Therefore, the present application sets a limit component 2 on the top of the four rectangular side templates 1. The limit component 2 can keep the four rectangular side templates 1 in the current state, thereby maintaining the stability of the rectangular structure.

[0027] like Figure 4 As shown, after pouring the concrete, when the mold needs to be stored, the worker first releases the limit of the limit assembly 2 on the four rectangular side templates 1, and the four rectangular side templates 1 can resume the active state, generating a movement similar to a four-bar linkage. The worker can straighten two of the connected rectangular side templates 1 around the rotating axis of the hinge at their connection, so that the planes where the two connected rectangular side templates 1 are located are coplanar. During the rotation process of the two rectangular side templates 1, the distance between their ends away from each other will gradually increase, and the ends away from each other of the two rectangular side templates 1 are connected to the ends away from each other of the other two rectangular side templates 1. Therefore, the two rectangular side templates 1 pull the other two rectangular side templates 1 to change together, and finally the four rectangular side templates 1 are stacked together to form a double-layer flat plate. When the four rectangular templates are lifted up and put together, the two split bottom plates 3 at the bottom will automatically rotate to a vertical state around the hinges at their respective ends under the action of gravity. At this time, all the rectangular side templates 1 and the split bottom plates 3 are still an integrated structure. When storing the mold of the present application, it is not necessary to separate the templates one by one and then store them in categories, as in the prior art, which is composed of multiple templates. Therefore, the mold of the present application reduces the labor of workers when storing the mold after use and improves the storage efficiency of the templates. When assembling the mold of the present application, it is not necessary to find the appropriate templates one by one from the template storage place, and then assemble them on site, and then fix them with multiple bolts on the edge of each template. Therefore, the mold of the present application is more convenient and quick to use.

[0028] Furthermore, if Figure 1 and Figure 2 As shown, the limiting assembly 2 includes four straight-slot-shaped limiting snap rings 21, and the four limiting snap rings 21 are respectively arranged above the connection points between the four rectangular side templates 1; two fixing units 22 are arranged in the slots of the limiting snap rings 21, and the two fixing units 22 can fix the two ends of the limiting snap ring 21 in the length direction to the tops of the two rectangular side templates 1 at their adjacent positions.

[0029] In the above embodiments, the straight-notch-shaped limiting clamp 21 of the present application is provided with upper and lower through-notches in the middle, which facilitates the installation of the fixing unit 22. After the four rectangular side templates 1 are surrounded by a rectangular structure, the worker can connect the limiting clamp 21 with the upper ends of the two adjacent rectangular side templates 1 close to each other through the fixing unit 22. Since the position of the limiting clamp 21 after fixation is fixed, the positions of the two adjacent rectangular side templates 1 corresponding to the limiting clamp 21 will not move. In this way, the four corners of the top of the rectangular structure surrounded by the four rectangular side templates 1 are fixed respectively by the four limiting clamps 21, thereby preventing the four rectangular side templates 1 from being deformed when the mold is pouring concrete.

[0030] Furthermore, if Figure 1 and Figure 2 As shown, the fixing unit 22 includes a fixing bolt 221, which passes through the notch on the limiting clamp 21 and the top plate of the rectangular side template 1 at the corresponding position from top to bottom. A first gasket 222 is provided between the end of the fixing bolt 221 and the limiting clamp 21, and the first gasket 222 is movably mounted on the fixing bolt 221. The lower end of the fixing bolt 221 is sequentially mounted with a second gasket 223 and a fixing nut 224 from top to bottom. The second gasket 223 is movably connected to the fixing bolt 221, and the fixing nut 224 is threadedly connected to the fixing bolt 221.

[0031] In the above embodiments, the first gasket 222 and the second gasket 223 of the present application are both metal gaskets, and their functions are to increase the contact area, reduce pressure, prevent loosening, and protect parts and fixing bolts 221. The fixing bolt 221 has a first gasket 222 at the part above the notch on the limiting clamp 21, and a second gasket 223 and a fixing nut 224 at the part below the notch on the limiting clamp 21, and the fixing nut 224 and the second fixing bolt 221 are also located below the top plate of the rectangular side formwork 1 below the limiting clamp 21. In this way, the worker screws the fixing nut 224 to bring the second gasket 223 and the first gasket 222 closer until the two tightly clamp the limiting clamp 21 on the rectangular side formwork 1, thereby fixing the limiting clamp 21 and the rectangular side formwork 1 together to limit the position.

[0032] Furthermore, if Figure 1 and Figure 4 As shown, the length of two limiting snap rings 21 above two opposite edges of the cuboid structure composed of four rectangular side templates 1 is greater than the length of the other two limiting snap rings 21 .

[0033] In the above embodiment, after the four rectangular side templates 1 are surrounded by a rectangular structure, two long limit snap rings 21 are respectively arranged above one group of relative edges of the rectangular structure, and the other two short limit snap rings 21 are respectively arranged above another group of relative edges of the rectangular structure. When the two corresponding rectangular side templates 1 below the short limit snap rings 21 are in a vertical state with each other, the distance between the fixing bolts 221 at the ends of the two rectangular side templates 1 close to each other is equal to the length of the notch in the short limit snap ring 21, so that when the rectangular side templates 1 are unfolded, when the two ends of the short limit slot are respectively in contact with the fixing bolts 221 at the ends of the two rectangular side templates 1 below it, all the rectangular side templates 1 just form a rectangular structure, which can facilitate workers to quickly unfold the four rectangular side templates 1 into a rectangular structure.

[0034] When the four rectangular side templates 1 need to be folded up, the angle formed by the rectangular side templates 1 corresponding to the two long limit snap rings 21 needs to be changed from a right angle to a flat angle. In this process, the distance between the two fixing bolts 221 at the ends of the two rectangular side templates 1 below the long limit snap rings 21 will gradually increase. Therefore, the length of the internal notch of the limit snap ring 21 above them is not less than the length when the two fixing bolts 221 are farthest apart, so as to ensure that the four rectangular side templates 1 can be smoothly folded together.

[0035] Furthermore, if Figure 1-Figure 3 As shown, the free end of one of the split bottom plates 3 is a positive step-shaped interface, and the free end of the other split bottom plate 3 is a matching inverted step-shaped interface; when the two split bottom plates 3 are rotated toward each other to a horizontal state, the free ends of the two split bottom plates 3 can be overlapped together.

[0036] In the above embodiments, when the two split bottom plates 3 are rotated toward each other to a horizontal state, the step-shaped interfaces at their mutually adjacent ends can be snapped together and overlapped, thereby lengthening the joint path between the two split bottom plates 3, thereby reducing the amount of concrete leakage from the joints of the split bottom plates 3 when pouring concrete.

[0037] Furthermore, if Figure 3 and Figure 4As shown, a plurality of semicircular grooves 4 are respectively provided below the ends of the two split bottom plates 3 that are close to each other along the length direction of the joint therebetween, a semi-cylinder 5 is respectively provided in the semi-circular groove 4, and a threaded line is provided on the outer side of the semi-cylinder 5; when the two split bottom plates 3 are rotated toward each other to a horizontal state, the semi-circular grooves 4 corresponding to each other at the positions below the two split bottom plates 3 can be respectively combined into a plurality of complete circular grooves; the semi-cylinders 5 corresponding to each other at the positions below the two split bottom plates 3 can be respectively combined into a plurality of complete cylinders, and after the two corresponding semi-cylinders 5 are combined into a complete cylinder, the threaded lines on the two semi-cylinders 5 will also be connected to each other.

[0038] In the above embodiment, a plurality of semicircular grooves are provided below the ends of the two split bottom plates 3 close to each other, and a semi-cylinder 5 with a threaded line on the outside is provided in each semi-circular groove 4. When the two split bottom plates 3 are rotated toward each other to a horizontal state, the semi-circular grooves 4 on the two split bottom plates 3 can just correspond one by one and merge into a complete circular groove, the semi-cylinders 5 in the corresponding grooves can merge into a complete cylinder, and the threads on the two semi-cylinders 5 that form the cylinder can just be connected at this time, and the outer side of the cylinder can be screwed with a nut that matches its specifications to connect the two semi-cylinders 5 together, so that the two split bottom plates 3 merged together form a stable overall structure, and the nut is screwed until it is completely immersed in the circular groove, so that when the mold is placed on the ground, the mold bottom template composed of the two split bottom plates 3 is in close contact with the ground and will not be lifted up by the nut.

[0039] Furthermore, if Figure 1 and Figure 3 As shown, the length of the split bottom plate 3 is greater than the width of the rectangular side template 1.

[0040] In the above embodiments, the length of the split bottom plate 3 of the present application is set according to the above-mentioned manner, so that when the mold is used, the split bottom plate 3 can provide a certain supporting force for the rectangular structure composed of four rectangular side templates 1, and the split bottom plate 3 can form a flat plane under the rectangular structure to prevent the split bottom plate 3 from being too small in width and rotating too much during assembly, so that the free end of the split bottom plate 3 extends into the interior of the rectangular structure.

[0041] The implementation principle of this embodiment is as follows: when the pier mold needs to be assembled before pouring the concrete pier, the worker can take the four folded rectangular side templates 1 and the two split bottom plates 3 to the area to be constructed, and then stretch the four rectangular side templates 1 first until the four rectangular side templates 1 form a rectangular structure that runs through the top and bottom, and then screw the fixing nuts 224 under the fixing bolts 221 in each limiting clamping ring 21, so as to fix the positions of the four unfolded rectangular side templates 1 by using the limiting clamping ring 21, and then the two split bottom plates 3 can be rotated toward each other so that the semicircular grooves 4 on their mutually approaching ends and the semi-cylinders 5 with external threads form a complete circular groove and a complete externally threaded cylinder, and then use the nut with the externally threaded cylinder to screw it onto the externally threaded cylinder that is spliced ​​together, so that the mold of the rectangular concrete pier composed of the four rectangular side templates 1 and the two split bottom plates 3 is assembled, and the pouring of concrete can begin.

[0042] When the mold needs to be stored after use, the nuts at the connection between the two split bottom plates 3 can be loosened first to restore a certain degree of freedom of the two split bottom plates 3, and then the fixing nut 224 under the fixing bolt 221 on the limiting clamp 21 can be loosened. While pulling the rectangular side template 1 upward, the two connected rectangular side templates 1 are squeezed toward the other two rectangular side templates 1 until they are attached together. At this time, the template can be folded into a plate-like shape with a double-layer structure, and workers can directly transport them to the warehouse as a whole.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
