Description

Technical Field

[0001] The invention relates to the field of prefabricated buildings, and in particular to a seismic connection structure of a prefabricated radiation-proof shielding building body. Background Art

[0002] Radiation shielding buildings are buildings that, based on the characteristics of electromagnetic waves, take structural measures in the building space to combine high-conductivity metal materials into various forms of shells or mesh covers and external protective structures, so that the building space has electromagnetic shielding performance. Its forms are divided into fixed room type, movable room type, assembled cage type, hanging type (i.e. hanging metal plates on the indoor surface) and jacket shielding layer room type, etc. according to the composition of the space; according to the metal shell and structure, it can be divided into metal flat plate, perforated metal shell plate, single-layer or double-layer metal wire mesh shell, metal plate and metal wire mesh composite shell and honeycomb metal mesh shell shielding room.

[0003] These shielding rooms are mostly used in places where high-precision instruments and high-end electronic equipment are installed to achieve anti-interference protection for internal equipment and ensure the normal operation of internal equipment. At the same time, because most of the equipment installed inside these shielding rooms is expensive, and the shielding room itself is expensive, the earthquake protection of the shielding room is particularly important.

[0004] At present, the earthquake protection structure of the shielding room is mainly formed by strengthening its structural rigidity, such as improving the number and type of beam and column steel bars and materials to improve the rigidity of the structure. And by adding auxiliary supports at key nodes, such as adding diagonal bracing rods on the side of the building. However, these methods cannot effectively release and buffer the earthquake energy and cannot achieve a good earthquake resistance effect. Summary of the invention

Since the first buffer hole and the second buffer hole of the present invention can both allow the buffer rod to slide inside, and the two are vertically staggered, the shaking shear force of earthquake waves from all directions can be released more stably, and the reliability is excellent.

[0029] Combination Figure 1-8 As shown, an anti-seismic connection structure of an assembled radiation shielding building can effectively improve the anti-seismic performance of the assembled shielding room, and is particularly suitable for use as a front-line communication command center room, surveying and mapping room, etc. in special occasions such as earthquake relief, etc., and has the characteristics of high stability, easy assembly, anti-interference spacing, and anti-seismic advantages. The present invention includes a rectangular base 1 for laying in a foundation pit and an assembled building body arranged on the base 1.

[0030] The base 1 of the present invention adopts an underground structure, and can be directly excavated in the field, and laid directly after leveling and compacting. Generally, the length and width of a base 1 are between 4-6 meters, and the height is between 30-60 centimeters. It is processed and poured in advance in the factory and can be paved after being transported to the site. It can be used alone or in combination to meet the requirements of building size.

[0031] The base 1 of the present invention adopts a hollow box-type base body, and the interior of the base 1 is divided into a plurality of rectangular cavities 22 by criss-crossing middle ribs 21. This hollow box-type structure has the advantage of light weight, and through the reinforced support of the middle ribs 21, it has the characteristics of good structural strength, and can enhance the rigidity of the base 1 itself. At the same time, the rectangular cavity 22 can be used as a storage cavity for storing liquid materials such as water and oil, and used as a storage space for domestic water, cooling water, and diesel for power generation. By dividing the rectangular cavity 22 into zones, partitioned storage can also be achieved. Of course, the rectangular cavities 22 in the same zone can be interconnected, and the connection method is generally that two adjacent rectangular cavities 22 in the zone are connected through the connecting holes located at the bottom of the middle ribs 21.

[0032] At the same time, the base 1 of the present invention, as the foundation of the entire building, needs to be in direct contact with the ground due to the need for supporting stability, but it itself has certain shock-absorbing and buffering performance. Specifically, the rectangular cavity 22 is also provided with a buffer plate 23 that slides up and down with the rectangular cavity 22. The rectangular cavity 22 below the buffer plate 23 is filled with liquid. When the rectangular cavity 22 is not needed as a storage space for liquid materials, the rectangular cavity 22 can be specifically filled with liquid, generally directly filled with water. A buffer spring 24 is provided between the buffer plate 23 and the top plate of the base 1. The top plate of the base 1 can generally be composed of the bottom enclosure plate of the building body, and of course it can also be provided separately.

[0033] By adopting the rectangular cavity 22 in combination with the buffer plate 23 and the buffer spring 24, when the base 1 is shaken by an earthquake, the liquid in the base 1 can buffer the earthquake shock through its own left and right fluctuations and up and down fluctuations, thereby achieving stress release. The impact force generated by the up and down fluctuations can also be further released through the up and down movement of the buffer plate 23 and the expansion and contraction of the buffer spring 24, which can avoid directly transmitting the vibration to the building body above the base 1, ensure the earthquake resistance of the base 1 itself, and improve the stability of the building body installed thereon.

[0034] The assembled building body described in the present invention includes a main frame and an assembled shielding plate 2. The assembled shielding plate 2 is a component that mainly plays a shielding role. It can adopt various existing shielding plate structures, for example: through external, internal or central metal shielding structures, such as metal flat plates, perforated metal shell plates, single-layer or double-layer metal wire mesh shells, metal plates and metal wire mesh composite shells, etc., to play a stable and effective shielding role. This structure is relatively mature and will not be emphasized in the present invention.

[0035] The main frame includes columns 3, bottom beams 0 and top beams. The columns and beams can generally be made of steel components, or prefabricated concrete components, or a combination of the two, with steel components as the component core and concrete as the component shell. Figure 1 As shown in, the columns 3 are arranged at the four corners of the base 1 and are connected to the base 1 through the seismic buffer seat 4. The seismic buffer seat 4 is used to buffer the vibration transmission between the building body and the base 1 to achieve stress release. The bottom beam 0 of the main frame is arranged between the lower ends of the columns 3 to form a bottom frame, and the assembly shielding plate 2 is arranged in the bottom frame to form a bottom enclosure. The top beam of the main frame is arranged between the upper ends of the columns 3 to form a top frame, and the assembly shielding plate 2 is arranged in the top frame to form a top enclosure. The side of the main frame is provided with an assembled shielding enclosure to form a side enclosure, so as to achieve shielding protection on all sides. For a taller building body, generally a building body of more than 6 meters, it can be formed by setting a middle section beam in the middle section of the column 3 of the main frame, and connecting through the middle section beam to form an intermediate frame, thereby playing a role in strengthening the main frame and the building body.

[0036] The assembled matching form of the beam column and the assembled shielding enclosure can generally be in the form of a snap-in connection, that is, the side of the column 3 is provided with a connecting slot 20, and the two ends of the assembled shielding enclosure are inserted into the connecting slot 20. Similarly, the top beam and the bottom beam can also be provided with a connecting slot 20 for the assembled shielding enclosure 2 to be snapped in.

[0037] As the key point of the present invention, the anti-seismic buffer seat 4 includes a connecting square platform 5 fixedly arranged on the top surface of the corner of the base 1, and the lower end of the column 3 is provided with a square column cavity 6, and is sleeved outside the connecting square platform 5 through the column cavity 6, and a gap of about 10-30 cm is reserved between the inner wall of the column cavity 6 and the connecting square platform 5. Figure 5 As shown, the connecting square platform 5 is provided with buffer holes, and the buffer holes include a first buffer hole 7 penetrating the connecting square platform 5 in the left-right direction, and a second buffer hole 8 penetrating the connecting square platform 5 in the front-back direction, and the first buffer hole 7 and the second buffer hole 8 are staggered up and down. Generally, 2-3 first buffer holes 7 and second buffer holes 8 are provided on each floor, and according to the height of the main building, multiple layers of first buffer holes 7 and second buffer holes 8 can be provided. A buffer rod 9 is penetrated in the buffer hole to form a sliding fit with the buffer hole. Through the relative sliding of the buffer rod 9 and the first buffer hole 7 and the second buffer hole 8, the present invention can fully offset the displacement of the base 1 caused by an earthquake, and ensure that the main building on the base 1 is not subject to excessive shearing effects.

[0038] like Figure 6 As shown, the buffer rod 9 of the present invention includes a rod body 10, and both ends of the rod body 10 are provided with contact ends 11 for supporting on the inner wall of the column cavity 6. The contact head 11 is not directly connected to the column cavity, but has the characteristic of sliding contact. A relatively simple contact method is that the contact end 11 is a contact disk, which directly contacts the inner wall of the column cavity 6 through a circular contact disk. Generally, since the shear wave of an earthquake mainly produces shearing action and the greatest damage, while the influence of the longitudinal wave is relatively small, the shear wave impact is mainly considered when performing seismic design. In order to ensure stable contact between the contact end 11 and the inner wall of the column cavity 6, another method that can be used is, such as Figure 8 As shown in , the contact end 11 is an I-shaped slider, and the inner wall of the column cavity 6 is provided with a horizontal (left and right, front and back) slide groove that matches the slide groove. Generally, the size of the slide groove is slightly larger than the contact end 11, which can avoid direct rigid contact while having a certain limit. The slide groove can be directly formed on the inner wall of the column cavity 6, or it can be installed in the form of bolt connection after being processed separately. Figure 4 As shown, the rod body 10 of the present invention is provided with a pressure plate 12 near the contact end 11 , and a pressure release spring 13 is provided on the outer sleeve of the rod body 10 , and the pressure release spring 13 is arranged between the pressure plate 12 and the connecting square platform 5 .

[0039] In application, a relatively movable non-rigid connection structure is used between the main building and the base 1, and the column cavity 6 on the column 3 is used to balance the compression of the buffer rod 9, and the support of the pressure relief spring 13 can ensure the stability between the main building and the base 1 (connecting square platform 5). When an earthquake occurs, the buffer rod 9 can slide in the first buffer hole 7 and the second buffer hole 8, thereby realizing the relative movement between the column 3 and the connecting square platform 5; the lateral shear impact on the base 1 can be released through the movement of the buffer rod 9 in the buffer hole and the compression of the pressure relief spring 13, avoiding the lateral shear shaking from being directly and losslessly transmitted to the main building, thereby ensuring the safety of the main building and internal equipment and facilities.

[0040] The present invention can adapt to the shear wave impact in various directions through the design of the first buffer hole 7, the second buffer hole 8 and the buffer rod 9, but the stress release is realized by decomposing the force of the impact force into the displacement of the first buffer hole 7 and the second buffer hole 8 in two length directions. Since there is a relatively close contact between the first buffer hole 7, the second buffer hole 8 and the buffer rod 9, and the influence of the material of the buffer rod 9, the force cannot be perfectly divided according to the theory, so there is always a certain force extrusion between the buffer rod 9 and the hole walls of the first buffer hole 7 and the second buffer hole 8 of the connecting square platform 5.

[0041] In order to buffer the force extrusion, the middle section of the rod body 10 is a variable diameter section 14, and the variable diameter section 14 is provided with a hard rubber sleeve 15. The middle section of the rod body 10 forms a sliding fit with the buffer hole through the hard rubber sleeve 15. The hard rubber sleeve 15 is a sleeve body supported by a relatively large hardness rubber. It has sufficient hardness to ensure normal sliding support, and when subjected to instantaneous impact, it can release the extrusion force through its own deformation ability. Of course, in an environment with frequent aftershocks and the hard rubber sleeve 15 has the risk of aging, the life of the hard rubber sleeve 15 is relatively lower than that of other components. It needs to be regularly inspected and replaced, and the form of the entire sleeve is not only not conducive to disassembly and maintenance, but also needs to be replaced as a whole. For this reason, a better approach of the present invention may be that an inspection door is provided on the side wall of the column 3 corresponding to the upper part of the column cavity 6. This structure is relatively simple and will not be described separately in the present invention.

[0042] The hard rubber sleeve 15 of the present invention is composed of a plurality of rubber rings 16, which are sleeved on the outside of the reducing section 14 to form the hard rubber sleeve 15. By replacing the rubber rings 16 individually, rapid maintenance can be achieved. Figure 7As shown in , a card interface 17 is provided on one side of the rubber ring 16, and a card block 18 matching the card interface 17 is provided on the other side opposite to the card interface 17. Two adjacent rubber rings 16 are arranged alternately, and the card block 18 of one rubber ring 16 is inserted into the card interface 17 of another rubber ring 16. Since the rubber ring 16 itself has a certain elasticity, the card interface 17 has a deformation ability and can be broken open and inserted. However, this method will sacrifice a part of the supporting force. For this reason, the present invention uses the design of the card block 18 to insert the card interface 17 into the card interface 17 to achieve the filling of the gap, thereby improving the overall stability and connection strength. Of course, since the rubber rings 16 at both ends are end parts, the card interface 17 can be provided at the corresponding part of the step surface of the rod body for the card block 18 to be inserted. The design of the rubber ring 16 with this method is not only conducive to replacement, but also can well guarantee the performance of the hard rubber sleeve.

[0043] In addition, if Figure 4 and 6 As shown in , the rod body 10 of a section of the buffer rod 9 between the pressure plate 12 and the card interface 17 can also be a rubber rod 19, which is also made of hard rubber, and the structural form of the hard rubber sleeve can be referred to. Of course, since its overall length is relatively short and its own strength is relatively sufficient, it is not necessary to set a specially installed diameter-changing section (core rod), but to directly connect the rubber component to the rod body components at both ends in the form of riveting and card connection. Through the provision of the rubber rod, the present invention can further reduce the risk of damage to the buffer rod 9 itself, thereby improving safety.
