Description

Technical Field

[0001] The utility model relates to an assembled building, and more specifically to a concrete assembled transformer substation base. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Substation bases are currently mostly constructed in the form of prefabricated buildings. Concrete components can be pre-processed in the production workshop and then transported to the field environment, so that substation equipment can be quickly built. The current substation base mainly includes a bottom plate and side plates around. The side plates are connected and fixed by connecting frames (angle brackets) to form a quadrilateral ring structure, which is placed on the bottom plate, and then fixed between the side plates and the bottom plate by connecting frames (angle brackets), and the side plates and the bottom plate are also connected and fixed. The side plates are mainly placed on the bottom plate by their own weight. Once the base is tilted and offset, there may be a risk of side sliding and lateral movement between the side plates and the bottom plate. During this process, each connecting frame will be subjected to a great force, which is easy to cause bending or even breaking. Therefore, the strength performance requirements of the connecting frames and embedded parts are very high.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This embodiment discloses a concrete assembled substation base, which is composed of a plurality of prefabricated concrete components and is suitable for the bottom structure of the substation. By building a roof and other structures on the top of the base, the external structure of the substation can be formed.

[0026] Reference Figure 1 As shown, the base mainly includes a bottom plate 1 and a side enclosure 2. The bottom plate 1 is generally a plate-shaped structure, including an upwardly disposed support surface 11. The side enclosure 2 includes four side plates 3, and the four side plates 3 are mutually surrounded to form a ring structure. The lower part of the side enclosure 2 is supported and fixed by the bottom plate 1, and can support the self-gravity load of each side plate 3.

[0027] The adjacent side panels 3 are connected and fixed by a connecting frame 6, which is roughly a right-angle structure, and the two sides of the connecting frame 6 are respectively connected and fixed to two adjacent side panels 3. The connecting frame 6 can keep the two side panels 3 in a stable connection state, and can limit the position through the structure of the connecting frame 6 itself, so that the two are kept in a roughly vertical state.

[0028] Furthermore, a concave-convex structure may be provided between two interconnected side panels 3, so that the two side panels 3 can be plugged and adapted to each other, and their positions are limited, thereby improving the stability and strength after connection.

[0029] Reference Figure 1 , Figure 2 As shown, a plurality of protrusions 31 are formed on the side of the side panel 3. The protrusions 31 are roughly in the shape of a rectangular parallelepiped, and the protrusions 31 are arranged equidistantly from top to bottom, and a limiting groove is formed between the upper and lower adjacent protrusions 31. The height dimension of the limiting groove is basically consistent with the height dimension of the protrusion 31, and the protrusions 31 and the limiting grooves of the two adjacent side panels 3 are adapted to each other. When the two side panels 3 are connected, the protrusion 31 of one side panel 3 is embedded in the limiting groove of the other side to achieve the card-connection limiting. The mutually plug-in matching structure can achieve the moving limiting in the up and down directions, and maintain the rotation limiting in the horizontal direction to ensure the stability of the connection between the adjacent side panels 3.

[0030] A through hole 41 is provided at the convex block 31, and a tubular embedded part 12 can be provided at the position of the convex block 31, so that a through hole 41-shaped structure can be formed at the position after solidification. The through holes 41 of the convex blocks 31 of two adjacent side panels 3 correspond to each other in the upper and lower positions, and a connecting rod 4 is provided at the through hole 41 that passes through the upper and lower positions. The convex blocks 31 of each of the two adjacent side panels 3 can be locked and limited by the connecting rod 4, so as to maintain the stability of the connection state of the two side panels 3.

[0031] An embedded part 12 is provided in the bottom plate 1, and the position of the embedded part 12 corresponds to the position of the protrusion 31, and specifically corresponds to the position of the through hole 41 of the protrusion 31. The upper end of the connecting rod 4 is fixedly connected to the limiting block 42, and the lower end is processed to form an external thread. The connecting rod 4 passes through the through holes 41 of each protrusion 31 downward, and the lower end can be threadedly connected with the embedded part 12; and the limiting block 42 at the upper end of the connecting rod 4 can be pressed against the upper side surface of the uppermost protrusion 31 to achieve the pressing limit, and the two side plates 3 and the bottom plate 1 can be connected and fixed by the screw, and the three mutually perpendicular plates are locked and connected.

[0032] Reference Figure 3 , Figure 4 As shown, a boss 13 is formed in the middle of the upper part of the bottom plate 1 , the boss 13 and the bottom plate 1 are an integrated structure, and a protrusion of a directional structure is formed in the middle position of the upper part of the bottom plate 1 .

[0033] When the side enclosure 2 is installed and fixed, the side panel 3 is enclosed at the outer periphery of the boss 13. The outer periphery of the boss 13 forms a stepped surface 131, and the stepped surface 131 faces the outer periphery of the side enclosure 2. The side surface of the side panel 3 can be pressed against the stepped surface 131 on the outer periphery of the boss 13 to limit the position. By matching the inner periphery of the side enclosure 2 with the outer periphery of the boss 13, a horizontal limit can be formed, which can limit the lateral deviation of the side panel 3 and ensure the stability of the position between the side panel 3 and the bottom plate 1.

[0034] Furthermore, the lower portion of the side panel 3 and the boss 13 of the bottom panel 1 are connected and fixed by a connecting frame 27. The shape of the connecting frame 27 is also roughly a right-angle structure. The two side edges of the connecting frame 27 can be connected and fixed to the boss 13 of the side panel 3 and the bottom panel 1 respectively, thereby maintaining the connection stability between the side panel 3 and the bottom panel 1 and playing a role of compensating fixation.

[0035] A plurality of notched grooves 14 are provided on the outer periphery of the boss 13, and the bottom surface of the notched grooves 14 is flush with the supporting surface 11, forming a concave groove structure on the inner bottom of the base. In addition, an inclined surface 141 is formed near the inner periphery of the boss 13 on the notched groove 14, and the inclined surface 141 is inclined upward toward the center direction of the boss 13, and can play a guiding role through the inclined surface 141, so that the accumulated water that may be generated on the upper part of the boss 13 can be introduced into the notched grooves 14, and the upper side surface of the boss 13 has a certain height relative to the bottom of the notched grooves 14, which can play a certain role in water isolation. In addition, each notched groove 14 can also provide space for the bottom plate 1 and the boss 13 to produce deformation, playing a role similar to that of an expansion joint.

[0036] In addition, when the width of the side panels 3 is large, a crossbeam 5 may be installed between two opposite side panels 3. Specifically, a notch may be provided on the upper side of the corresponding side panel 3, and the shape of the notch matches the shape of the crossbeam 5. The crossbeam 5 is embedded in the notch and connected and fixed by a connecting frame of a corresponding shape. The crossbeam 5 can strengthen the strength of the two side panels 3, further improving the overall structural stability of the base.

[0037] In addition, the outer peripheral contour of the bottom plate 1 is larger than the outer peripheral contour of the side enclosure 2. After the side enclosure 2 is installed, the bottom plate 1 will form a circle of protruding structures protruding from the side enclosure 2, and the ring will surround the lower outer peripheral position of the base. The larger structure can ensure that the bottom can stably support the side enclosure 2.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
