Description

Technical Field

[0001] The invention relates to the technical field of arc-shaped ceiling structures, and in particular to an arc-shaped structure based on a plug-in modular stainless steel pool cover. Background Art

[0002] As a common space covering solution in modern buildings, plug-in modular curved ceiling structures have been widely used in public buildings, industrial plants and environmental protection facilities (such as sewage treatment plants, garbage transfer stations) and other fields. This technology uses a plug-in assembly process with a high-strength bolt connection system, which significantly improves the construction efficiency of the curved structure. To ensure the sealing performance of the curved ceiling, elastic sealing pads are usually installed at the joints of the modules to reduce the possibility of water leakage (public buildings or warehouses) or the possibility of the collected gas (sewage treatment plants) leaking out. Since standard modules mostly use large-span metal curved plates, the curved plates are heated. The influence of expansion and contraction is great. In the high temperature environment in summer, the metal sheet expands due to heat and produces longitudinal deformation, which continuously squeezes the end sealing strip. When it shrinks due to low temperature in winter, the gap between the joints expands and the sealing material needs to rebound to compensate. This periodic stress alternation accelerates the aging of traditional sealing materials, causing the sealing effect of the sealing strip to deteriorate, affecting the overall sealing performance of the curved ceiling, and even causing the sealing of the curved ceiling to fail. At this time, rainwater leakage will occur in the storage scenario, leading to damage to the goods, and in the sewage treatment facilities, it will cause the escape of foul-smelling gases, affecting the surrounding environment and posing a safety hazard.

[0003] In addition, traditional curved ceilings generally use an internal frame structure to support the ceiling force. If corrosive gases are volatilized inside the pool, it will accelerate the aging of the structure and shorten its service life; or it will need to be replaced with more corrosion-resistant materials, increasing costs.

DETAILED DESCRIPTION

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the shape, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0022] Example 1: An arc-shaped structure based on a plug-in modular stainless steel pool cover, referring to Figure 1-Figure 10 , comprising two fixing members 1, an arch plate 2 is arranged between the two fixing members 1, the arch plate 2 is composed of an arc-shaped steel plate 21 and two bolted steel plates 22, the bolted steel plates 22 are fixedly connected to the adjacent fixing members 1 by a plurality of first bolts 101, a first rubber pad 23 is arranged between the bolted steel plates 22 and the adjacent fixing members 1, the back sides of the two outermost arc-shaped steel plates 21 are fixedly connected to the side sealing steel plates 3 by a plurality of second bolts 301, and the side sealing steel plates 3 and the fixing members 1 are fixedly connected by the second bolts 301. The bolt 301 is fixed, a second rubber pad 24 is arranged between the arc-shaped steel plate 21 and the adjacent side sealing steel plate 3, a third rubber pad 25 and a plurality of third bolts are arranged between two adjacent arc-shaped steel plates 21, a U-shaped rubber 4 is fixed to the fixing member 1, the U-shaped rubber 4 is fitted and sealed with the adjacent bolted steel plate 22, and locking mechanisms are arranged on the bolted steel plate 22 at intervals, and the number of the locking mechanisms is the same as the number of the first bolts 101, and the locking mechanisms are used to lock the adjacent U-shaped rubbers 4 on the adjacent bolted steel plates 22.

[0023] The shape of the curved steel plate 21 is as follows: Figure 4 As shown, it is composed of a concave portion and a convex portion connected in sequence. Figure 1 There are three arched plates 2 shown in total, wherein the two bolted steel plates 22 in each arched plate 2 are respectively located on the left and right sides of the adjacent arcuate steel plate 21. When the arched plate 2 expands and contracts due to heat and cold, the left and right sides expand and contract to a large extent, while the front and rear sides expand and contract to a small extent. Therefore, the second rubber pad 24 and the third rubber pad 25 of the arcuate steel plate 21 are subjected to less extrusion pressure, and their service life is less affected. However, the first rubber pad 23 is susceptible to excessive extrusion during use, and its service life is shortened. Therefore, in this solution, the second rubber pad 24 and the third rubber pad 25 of the arcuate steel plate 21 are not designed, and the first rubber pad 23 is only used to buffer the thermal expansion and contraction of the arched plate 2. The sealing between the bolted steel plate 22 and the adjacent fixing member 1 mainly relies on the U-shaped rubber 4. The above metal parts are all made of stainless steel to reduce the influence of corrosive gases and reduce the aging rate of the structure.

[0024] In the above scheme, the fixing member 1 on the left side is a pre-buried steel plate (such as Figure 5 As shown in the figure, the fixing member 1 on the right side is an angle steel (as shown in the figure Figure 4As shown), the fixing member 1 is used to provide a stable supporting force for the arch plate 2. The specific structure and installation sequence of the two fixing members 1 can be adjusted according to the actual application environment; the arch plate 2 is a structure welded by an arc-shaped steel plate 21 and a bolted steel plate 22. The fixing member 1, the arch plate 2 and the side sealing steel plate 3 are all provided with plugs and sockets for plugging. When assembling the present device, the fixing member 1, the arch plate 2 and the side sealing steel plate 3 are first plugged and installed in sequence, and then fixed uniformly with bolts. Because all the plugs and sockets adopt the existing structure, they are not specifically shown in the figure; the arc-shaped steel plate 21 is provided with spaced horizontal ribs and spaced vertical ribs to enhance the strength of the arch plate 2 and reduce the probability of collapse of the arch plate 2 after being subjected to external force.

[0025] As a preference, refer to Figure 8 The arc-shaped steel plate 21 is provided with ribbed folded edges 211 and biting edges 212 at the ends of the folded edges 211 .

[0026] As a preference, refer to Figure 6 and Figure 7 The third rubber pad 25 is located between the folded edges 211 of adjacent arc-shaped steel plates 21. The outer sides of the folded edges 211 connecting two adjacent arc-shaped steel plates 21 are connected with unequal angle steels 102 through third bolts. The unequal angle steels 102 maintain the same curvature and bolt hole spacing as the folded edges 211 of the arc-shaped steel plates 21. When the span of the arc-shaped steel plates 21 increases, the unequal angle steels 102 between the two arc-shaped steel plates 21 play a supporting role to increase the structural strength.

[0027] As a preference, refer to Figure 1-Figure 6 The arc-shaped steel plate 21 is provided with horizontal ribs and vertical ribs distributed at intervals.

[0028] As a preference, refer to Figure 7 , Fig. 9 and Figure 12-14 An elastic steel plate 5 is fixed to the upper side of the U-shaped rubber 4, the elastic steel plate 5 is in contact with the U-shaped rubber 4, the elastic steel plate 5 is provided with a fixing portion 52, the fixing portion 52 is fixed to the adjacent fixing member 1, and the sum of the thickness of the U-shaped rubber 4 and the thickness of the elastic steel plate 5 is less than the spacing at the U-shaped opening of the elastic steel plate 5.

[0029] In the above scheme, the shape of the elastic steel plate 5 is as follows: Fig.13 and Fig.14As shown, the elastic steel plate 5 wraps the upper part of the U-shaped rubber 4 to block the connection between the U-shaped rubber 4 and the space above it, thereby reducing the probability of the U-shaped rubber 4 being corroded by the external humid air after infiltrating the first rubber pad 23, thereby extending the service life of the U-shaped rubber 4. The sum of the thicknesses of the U-shaped rubber 4 and the elastic steel plate 5 is less than the spacing at the U-shaped opening of the elastic steel plate 5, thereby increasing the buffering distance of the U-shaped rubber 4 and the U-shaped structure on the elastic steel plate 5, thereby increasing the buffering performance of the U-shaped rubber 4 and the elastic steel plate 5.

[0030] As a preference, refer to Figure 10-13 The locking mechanism includes an extrusion plate 6, which is rotatably connected to the adjacent bolted steel plate 22, and an elastic member is installed between the two. The U-shaped rubber 4 is provided with a protrusion 41, and the elastic steel plate 5 is provided with a bending portion 51. The extrusion plate 6 fixes the elastic steel plate 5 and the U-shaped rubber 4 by extruding the bending portion 51. The bolted steel plate 22 is slidably connected with an extrusion block 7, and the extrusion block 7 is used to squeeze the adjacent extrusion plate 6 to rotate the adjacent extrusion plate 6. The first bolt 101 squeezes the adjacent extrusion block 7 to move the adjacent extrusion block 7.

[0031] In the above scheme, the shape of the extrusion plate 6 is as follows Fig.13 As shown, the elastic member on the extrusion plate 6 is a torsion spring. In the initial state, the elastic member on the extrusion plate 6 has no force stored, and the extrusion block 7 protrudes from the surface of the adjacent bolted steel plate 22. Fig.12 The extrusion block 7 is in a state of being squeezed and retracted by the adjacent first bolt 101. At this time, the extrusion plate 6 is squeezed by the extrusion block 7 and swings to a state of limiting the adjacent bending portion 51. The elastic member on the extrusion plate 6 is in a torsion storage state (with Fig.11 The state of the elastic member on the middle extrusion plate 6 is the same).

[0032] As a preference, refer to Fig.13 and Fig.14 The extrusion plate 6 is provided with spaced extrusion protrusions 61 on one side close to the bending portion 51, and the bending portion 51 is provided with a plurality of extrusion grooves 62 corresponding to adjacent extrusion protrusions 61 one by one. The extrusion protrusions 61 are inserted into adjacent extrusion grooves 62 to assist the extrusion plate 6 in limiting the elastic steel plate 5.

[0033] In the above solution, when the extrusion plate 6 extrudes the bent portion 51 , the extrusion protrusion 61 gradually inserts into the adjacent extrusion groove 62 , thereby reducing the probability of the elastic steel plate 5 sliding relative to the extrusion plate 6 .

[0034] The working principle of the above scheme is as follows: when the staff installs the device, taking the installation on the top of the pool as an example, the staff first fixes the left fixing piece 1 and the side sealing steel plate 3 on the left side of the top of the pool, and then splices the arch plate 2 on the fixing piece 1 and the side sealing steel plate 3 in sequence, and sequentially places the first rubber pad 23, the second rubber pad 24 and the third rubber pad 25 on the arc steel plate 21, and then the staff installs the first bolt 101, the second bolt 301 and the third bolt on the arc steel plate 21 in the splicing order, and finally fixes the right fixing piece 1, and after connecting the right fixing piece 1 with the arch plate 2, fixes the right fixing piece 1 to the upper part of the pool by the expansion bolt, and installs the device as follows: Figure 1 The status shown in .

[0035] During the installation process, taking the installation of the first bolt 101 on the left fixing member 1 as an example, when the staff inserts the bolted steel plate 22 into the fixing member 1, the U-shaped rubber 4 only relies on its own elastic force and the elastic force of the elastic steel plate 5 to maintain a fit with the bolted steel plate 22. At this time, the extrusion plate 6 is not in contact with the elastic steel plate 5. The staff inserts the first bolt 101 into the corresponding bolt hole and makes the first bolt 101 contact with the adjacent extrusion block 7. Then the staff gradually tightens the first bolt 101. During this process, the first bolt 101 squeezes the extrusion block 7 to move to the right. During the movement, the extrusion block 7 The adjacent extrusion plates 6 are squeezed to deflect downward, and the elastic parts on the extrusion plates 6 are twisted to store force. The extrusion plates 6 squeeze the bent portions 51, and the bent portions 51 and the raised portions 41 are squeezed and fixed on the bolted steel plates 22, so that the U-shaped rubber 4 and the bolted steel plates 22 always maintain a sealed fit, thereby reducing the probability of the U-shaped rubber 4 being out of contact with the bolted steel plates 22 due to vibration. In this process, the extrusion protrusions 61 are inserted into the adjacent extrusion grooves 62, and the elastic steel plates 5 are further fixed, thereby reducing the probability of the elastic steel plates 5 sliding relative to the extrusion plates 6, and thereby enhancing the fixing effect of the extrusion plates 6 on the elastic steel plates 5.

[0036] After the staff installs the device, in summer, when the arch plate 2 expands due to high temperature, the lateral deformation (in the left-right direction) of the arch plate 2 is large, and the longitudinal deformation (in the front-back direction) is small. At this time, the first rubber pad 23, the second rubber pad 24 and the third rubber pad 25 on the arc-shaped steel plate 21 are all squeezed, and the deformation of the second rubber pad 24 and the third rubber pad 25 on the arc-shaped steel plate 21 is small, and the deformation of the first rubber pad 23 is large. However, at this time, the first rubber pad 23 only provides a buffering function, and the U-shaped rubber 4 closes the gap between the arch plate 2 and the fixing member 1. The U-shaped rubber 4 is sealed, and the U-shaped rubber 4 is squeezed by the arch plate 2. The opening distance of the U-shaped rubber 4 becomes smaller, and the thickness change of the U-shaped rubber 4 is small. The U-shaped rubber 4 will not be over-extruded. When winter comes, the arch plate 2 shrinks and deforms. The arch plate 2 is squeezed by the squeezing plate 6 to drive the U-shaped rubber 4 to move together, so that the U-shaped rubber 4 and the arch plate 2 always maintain a sealed fit. At this time, even if the first rubber pad 23 cannot completely fill the gap between the fixing member 1 and the arch plate 2, the U-shaped rubber 4 can still seal the gap between the fixing member 1 and the arch plate 2, thereby maintaining the stability of the device.

[0037] Embodiment 2: The rubber pads of the existing devices are usually exposed to the air. Therefore, when the weather changes and it starts to rain or snow, the rain and snow will directly contact the rubber pads and soak the contacted rubber pads, causing the aging speed of the rubber pads to accelerate.

[0038] Based on Example 1, as a preferred embodiment, Figure 6-Figure 10 , and also includes shielding plates 8 whose number is the same as the bolted steel plates 22. The shielding plates 8 are fixed to the adjacent fixing members 1 through the first bolts 101 close to the adjacent bolted steel plates 22. The shielding plates 8 are used to shield the adjacent first rubber pads 23. The shielding plates 8 are provided with guide portions 81.

[0039] In the above scheme, the shielding plate 8 is used to shield the exposed part of the first rubber pad 23, reduce the impact of rain and snow on the first rubber pad 23, and then maintain the elastic performance of the first rubber pad 23, and extend the service life of the first rubber pad 23. At the same time, because the shielding plate 8 is assembled and unassembled using the first bolt 101, it is convenient for the staff to disassemble and assemble the shielding plate 8, thereby reducing the obstruction of the shielding plate 8 to the staff in maintaining the first rubber pad 23. After being deformed, the shielding plate 8 can be installed in the gap between the two arch plates 2 and the gap between the arch plate 2 and the side sealing steel plate 3, thereby protecting the second rubber pad 24 and the third rubber pad 25 on the arc steel plate 21.

[0040] As a preference, refer to Fig.10 , Fig.12 , Fig.13 and Fig.15The bolted steel plate 22 is fixedly connected with the spaced blocking plate 9 through the adjacent first bolts 101. The bolted steel plate 22 is provided with spaced water pipes 94. The water pipes 94 are slidably connected to the adjacent fixing parts 1. The water pipes 94 are used to discharge rainwater on the upper side of the arch plate 2 to the outside.

[0041] In the above scheme, the water pipe 94 is used to discharge rainwater accumulated on the upper side of the arch plate 2 during rain and snow, and the blocking plate 9 is used to block the upper part of the water pipe 94, thereby reducing the probability of leaves or garbage directly blocking the water pipe 94. The water pipe 94 is located above the U-shaped rubber 4, so that the U-shaped rubber 4 intercepts rainwater that penetrates the sliding connection between the water pipe 94 and the adjacent fixing member 1, and because the upper part of the U-shaped rubber 4 is covered by the elastic steel plate 5, the probability of rainwater entering the elastic steel plate 5 corroding the U-shaped rubber 4 is reduced; when the staff installs the blocking plate 9 on the Fig.15 In the position shown, the first bolt 101 pushes the blocking plate 9 to move, so that the blocking plate 9 squeezes the squeezing block 7 to move.

[0042] As a preference, refer to Fig.13 and Fig.15 The side of the blocking plate 9 away from the water pipe 94 is fixedly connected with the blocking bars 91 which are distributed at intervals. The blocking plate 9 and the blocking bars 91 are used together to block the upper part of the adjacent water pipe 94. The upper side of the blocking plate 9 is provided with through holes 92 which are distributed at intervals. The upper side of the blocking plate 9 is provided with support plates 93 which are distributed at intervals. The support plates 93 correspond to the through holes 92 one by one, and the support plates 93 are located at the upper part of the adjacent through holes 92.

[0043] In the above scheme, the blocking bar 91 is used to form a fence-like structure to reduce the probability of rainwater carrying the leaves on the arch plate 2 to the water pipe 94 when flowing downward along the arch plate 2. Even if the blocking bar 91 is blocked by most of the garbage, so that the rainwater cannot be discharged smoothly from the water pipe 94, the rainwater can also be discharged outward from the through hole 92 on the upper side of the blocking plate 9. The support plate 93 is composed of an inclined plate and an inclined rod. The support plate 93 is located above the through hole 92 to reduce the probability of fallen leaves adhering to the through hole 92 of the blocking plate 9. At the same time, because the fallen leaves are in an inclined state when they fall on the support plate 93, it is easier for the wind to blow the fallen leaves to the outside of the device, thereby reducing the accumulation of fallen leaves.

[0044] The working principle of the above scheme is as follows: when the staff installs the first bolt 101, the staff fixes the baffle plate 8 on the adjacent fixing part 1 through the first bolt 101, and fixes the blocking plate 9 on the arch plate 2. Then, when it rains, the baffle plate 8 protects the first rubber pad 23 to reduce the degree of erosion of the first rubber pad 23 by rainwater. After the rainwater on the arch plate 2 flows to the water pipe 94, it flows out from the water pipe 94. The blocking strip 91 and the support plate 93 intercept the fallen leaves on the top of the arch plate 2 to reduce the probability of the fallen leaves blocking the water pipe 94. During daily maintenance, the staff cleans the fallen leaves and garbage intercepted by the blocking plate 9. When the fallen leaves and garbage enter the lower side of the blocking plate 9, the staff can completely remove the blocking plate 9 by removing the first bolt 101, and then clean the garbage and fallen leaves at the water pipe 94.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
