Description

Technical Field

[0001] This invention relates to the field of spatial membrane installation technology, and in particular to a node arching device for large stadium spatial membrane structures. Background Technology

[0002] With the widespread application of membrane structures in the construction process, various types of exhibition halls and membrane structure buildings of different sizes across the country have been more widely used as membrane structure technology has developed. In large venues, membrane structures are often chosen for the roof design.

[0003] Membrane structures are a branch of steel structures, including membrane material installation, aluminum profile installation, cable and anchor installation. During the installation of spatial membranes, in order to ensure the installation of membrane nodes, the arching of the nodes is divided into arching treatment of the whole membrane and arching treatment of membrane connection. The existing arching treatment of membrane connection uses customized tension-bending aluminum materials to fix the two spatial membranes, thereby fixing the position of the spatial membrane, and arching treatment is performed at the membrane node position.

[0004] However, after the space membrane is installed, it is subjected to external forces, causing the space membrane to deform under stress. This results in the space membrane being stretched inside the aluminum material, which can easily cause deformation and damage at the connection points of the space membrane, resulting in poor connection at the space membrane nodes. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where the spatial membrane is subjected to external forces, causing deformation and hard pulling inside the bent aluminum material, which easily leads to deformation and damage at the connection points of the spatial membrane and poor connection effect at the nodes. Therefore, this invention proposes a node arching device for spatial membrane structures in large stadiums.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A node arching device for a large venue space membrane structure includes a bending plate, which is a U-shaped plate with an inclined upper end on its inner side. Sliding openings are provided at the diameter changes on both sides of the bending plate. A limiting component is slidably disposed inside the sliding opening. A deflection groove is provided at the bottom of the sliding opening. The limiting component includes a sliding plate, a locking strip, and a limiting strip. The locking strip is fixedly connected to the bottom end of the sliding plate and is used to limit the position of the sliding plate. The limiting strip is fixedly connected to the upper end of the sliding plate on both sides, and is a right-angled triangle with the right-angled side on the upper side. A trapezoidal space is formed between the two limiting strips. Fixing grooves are provided on the sides of the bending plate and the sliding plate, and the bending plate and the sliding plate are connected by bolts.

[0008] The bending plate has a blocking block inside. The upper end of the blocking block is trapezoidal and the two sides of the bottom end are rounded. The blocking block is used to restrict the space membrane.

[0009] A sealing assembly is provided on the upper side of the bending plate. The sealing assembly includes a top plate. A clamping assembly is provided between the top plate and the bending plate. The clamping assembly includes a first elastic block and a second elastic block. Both the first elastic block and the second elastic block are hemispherical blocks and are made of elastic material. Multiple first elastic blocks are fixedly connected to both sides of the top plate, and multiple second elastic blocks are fixedly connected to both sides of the upper side of the bending plate. The first elastic blocks and the second elastic blocks are staggered to fix the space membrane.

[0010] Preferably, the sealing assembly includes a sealing plate and a fixing bolt. The sealing plate is fixedly connected to the middle of the bottom surface of the top plate. Fixing openings are provided at the four corners of the upper end of the top plate and the bending plate. The fixing bolt passes through the top plate and is fixed to the bending plate.

[0011] Preferably, the slide plate is provided with a compression component, which is used to compress and fix the spatial membrane located between the first elastic block and the second elastic block.

[0012] Preferably, the extrusion assembly includes a push plate, a slide bar, and an elastic ball. A sliding opening is provided between the slide plate and the limiting strip. Multiple sliding openings are equidistantly arranged on the slide plate. The sliding openings are inclined, with one end located at the upper end of the slide plate and the other end located at the side of the limiting strip. The upper end of the sliding opening is configured as a hemispherical groove. The slide bar is slidably disposed inside the sliding opening. The elastic ball is fixedly connected to the upper end of the slide bar and is engaged inside the hemispherical groove. The push plate is fixedly connected to the bottom ends of the multiple slide bars.

[0013] Preferably, the plurality of elastic balls are arranged in parallel with the second elastic blocks, and the first elastic block is positioned between the two elastic balls and the two second elastic blocks.

[0014] Preferably, the upper end of the bending plate is symmetrically fixedly connected with pads on both sides. The pads are long strips with an arc-shaped cross-section and are made of rubber.

[0015] Preferably, a split arch assembly is provided below the bending plate, the split arch assembly being used to connect the cable connected to the space membrane.

[0016] Preferably, the arch assembly includes an arch rod and stiffening plates, with multiple stiffening plates equidistantly fixedly connected to the arch rod. The stiffening plates have fixing openings on both sides and are used to connect cables.

[0017] Preferably, an adjustment assembly is provided between the arch rod and the tension plate. The adjustment assembly includes a threaded column, a swivel, and a connecting block. The threaded column is threadedly connected to the lower part of the tension plate. The swivel is fixedly sleeved on the upper end of the threaded column. The connecting block is fixedly connected to the bottom end of the threaded column and is fixedly connected to the upper side of the arch rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When installing the membrane on both sides, the limiting component is pulled upward inside the sliding opening. When the locking strip moves to the deflection groove, it shifts outward, thereby exposing the inside of the bending plate. The membrane on both sides is then stacked and wrapped around the blocking block. After the space membrane is installed, the sliding plate is fixed inside the bending plate, and the limiting strips on both sides limit and block the blocking block. There is a certain deformation space above the blocking block that is not in contact with the limiting strip. During the stretching of the space membrane, the moving blocking block can deform to a certain extent, avoiding the stretching and deformation of the space membrane.

[0020] 2. The internal blocking blocks are limited and fixed by the top plate. At the same time, the first and second elastic blocks, which are set at equal intervals, can alternately clamp the space membrane on both sides. The space membrane is fixed by the elastic blocks, which will not cause hard wear and elastically restrict the space membrane.

[0021] 3. When the membrane is deformed by force, it is pulled to move, thereby causing the blocking block to move upward. During the upward movement of the blocking block, it will squeeze the push plate, causing the slide rod and elastic ball to move upward. Through the squeezing action of the elastic ball and the first elastic block, the position of the membrane is moved by the elastic blocking membrane. When the space membrane is not subjected to external force, the squeezing component plays the role of clamping and fixing the space membrane. When the space membrane is subjected to force, the squeezing component deforms under force, which can pressurize and fix the space membrane.

[0022] 4. Since the required arching angle is different for different film-separation positions, in order to facilitate the fixing of the film-separation position, the rotating ring drives the threaded column to rotate, thereby adjusting the arch rod and the bending plate to bend, and adjusting the required film-separation angle.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0032] Reference Figure 1-6 A node arching device for a large venue space membrane structure includes a bending plate 1, which is a U-shaped plate with an inclined upper end on the inner side. Sliding openings are provided at the diameter change points on both sides of the bending plate 1. A limiting component 2 is slidably installed inside the sliding opening. A deflection groove is provided at the bottom of the sliding opening. The limiting component 2 includes a sliding plate 21, a locking strip 22, and a limiting strip 23. The locking strip 22 is fixedly connected to the bottom end of the sliding plate 21 and is used to limit the position of the sliding plate 21. The limiting strip 23 is fixedly connected to the upper end of the sliding plate 21 on the side that are close to each other. The limiting strip 23 is a right triangle with the right angle side located on the upper side. A trapezoidal space is formed between the two limiting strips 23. Fixing grooves are provided on the sides of the bending plate 1 and the sliding plate 21, and the bending plate 1 and the sliding plate 21 are connected by bolts.

[0033] The bending plate 1 has a blocking block 3 inside. The upper end of the blocking block 3 is trapezoidal and the bottom two sides are rounded. The blocking block 3 is used to restrict the space membrane. During the installation of the membrane, the two membrane edges are stacked under the blocking block 3 and the sides are wrapped around the sides of the blocking block 3. When installing the membrane on both sides, the limiting component 2 is pulled up inside the sliding opening. When the locking strip 22 moves to the deflection groove, it is offset outward, thereby exposing the inside of the bending plate 1 and stacking the membrane on both sides to wrap the blocking block 3. After the space membrane is installed, the sliding plate 21 is fixed inside the bending plate 1 and the limiting strips 23 on both sides limit and block the blocking block 3. There is a certain deformation space above the blocking block 3 that is not in contact with the limiting strip 23. During the stretching of the space membrane, the moving blocking block 3 can deform to a certain extent to avoid the stretching and deformation of the space membrane.

[0034] A sealing component 4 is provided on the upper side of the bending plate 1. The sealing component 4 includes a top plate 41. A clamping component 5 is provided between the top plate 41 and the bending plate 1. The clamping component 5 includes a first elastic block 51 and a second elastic block 52. The first elastic block 51 and the second elastic block 52 are both hemispherical blocks and are made of elastic material. Multiple first elastic blocks 51 are fixedly connected to both sides of the top plate 41, and multiple second elastic blocks 52 are fixedly connected to both sides of the upper end of the bending plate 1. The first elastic blocks 51 and the second elastic blocks 52 are staggered to fix the space membrane. The top plate 41 limits and fixes the internal blocking block 3. At the same time, the space membrane on both sides can be staggered by the equidistant first elastic blocks 51 and the second elastic blocks 52. The space membrane is fixed by the elastic blocks, which will not cause hard wear and elastically restricts the space membrane.

[0035] In the embodiments applying the above technical solution, when installing the two side membranes, the limiting component 2 is pulled upward inside the sliding opening. When the locking strip 22 moves to the deflection groove, it shifts outward, thereby exposing the inside of the bending plate 1. The two side membranes are then stacked and wrapped around the blocking block 3. After the space membrane is installed, the sliding plate 21 is fixed inside the bending plate 1, and the blocking block 3 is limited and blocked by the limiting strips 23 on both sides. There is a certain deformation space above the blocking block 3 that is not in contact with the limiting strip 23. During the stretching of the space membrane, the moving blocking block 3 can deform to a certain extent, avoiding the stretching and deformation of the space membrane. The top plate 41 limits and fixes the internal blocking block 3. At the same time, the first elastic block 51 and the second elastic block 52, which are set at equal intervals, can alternately clamp the space membranes on both sides. The space membrane is fixed by the elastic blocks, which will not cause hard wear. The space membrane is elastically restricted. This invention provides deformation space for the stretching of the installed membrane through elastic fixation, reducing the deformation and damage of the space membrane.

[0036] In this preferred embodiment, the sealing assembly 4 includes a sealing plate 42 and a fixing bolt 43. The sealing plate 42 is fixedly connected to the middle of the bottom surface of the top plate 41. Fixing openings are provided at the four corners of the upper end of the top plate 41 and the bending plate 1. The fixing bolt 43 passes through the top plate 41 and is fixed to the bending plate 1. The space in the middle of the bending plate 1 can be sealed by the sealing plate 42 above. At the same time, the first elastic block 51 and the second elastic block 52 on both sides can also play a sealing role. The fixing bolt 43 is used to fix the top plate 41 and the bending plate 1.

[0037] The slide plate 21 is provided with an extrusion component 6. The extrusion component 6 is used to extrude and fix the position of the space membrane located between the first elastic block 51 and the second elastic block 52. Due to the deformation and movement of the membrane, after buffering the tension, in order to ensure that the membrane is not pulled hard, the extrusion component 6 strengthens the elastic resistance to the membrane.

[0038] The extrusion assembly 6 includes a push plate 61, a slide rod 62, and an elastic ball 63. A sliding opening is provided between the slide plate 21 and the limiting strip 23. Multiple sliding openings are equidistantly arranged on the slide plate 21. The sliding openings are inclined, with one end located at the upper end of the slide plate 21 and the other end located at the side of the limiting strip 23. The upper end of the sliding opening is set as a hemispherical groove. The slide rod 62 is slidably arranged inside the sliding opening. The elastic ball 63 is fixedly connected to the upper end of the slide rod 62 and is locked inside the hemispherical groove. The push plate 61 is fixedly connected to the bottom end of multiple slide rods 62. When the membrane is deformed by force, it pulls the membrane to move, thereby driving the blocking block 3 to move upward. During the upward movement of the blocking block 3, it will squeeze the push plate 61, driving the slide rod and the elastic ball 63 to move upward. Through the squeezing action of the elastic ball 63 and the first elastic block 51, the position of the membrane is moved by the elastic blocking membrane. When the spatial membrane is not subjected to external force, the extrusion assembly 6 plays the role of clamping and fixing the spatial membrane. When the spatial membrane is subjected to force, the extrusion assembly 6 deforms under force, which can pressurize and fix the spatial membrane.

[0039] Multiple elastic balls 63 are arranged in parallel with the second elastic blocks 52. The first elastic block 51 is positioned between the two elastic balls 63 and the two second elastic blocks 52. The staggered arrangement of the elastic balls 63 and the second elastic blocks 52 can fix the first elastic block 51, thereby fixing the position of the space membrane.

[0040] The upper ends of the bending plate 1 are symmetrically fixed with pads 10. The pads 10 are long strips with an arc-shaped cross section. The pads 10 are made of rubber. The pads 10 are used to contact the edge of the space membrane to avoid deformation and wear of the space membrane. The rubber material can effectively protect the bending plate 1.

[0041] A split-arch assembly 8 is provided below the bending plate 1. The split-arch assembly 8 is used to connect the cable connected to the space membrane.

[0042] The arch component 8 includes an arch rod 81 and stiffening plates 82. Multiple stiffening plates 82 are fixedly connected to the arch rod 81 at equal intervals. The stiffening plates 82 have fixing openings on both sides. The stiffening plates 82 are used to connect the cables. The arch rod 81 is connected to the tension plate 1, and the multiple stiffening plates 82 are used to fix the position of the cables.

[0043] An adjustment assembly 9 is provided between the arch rod 81 and the bending plate 1. The adjustment assembly 9 includes a threaded column 91, a rotating ring 92, and a connecting block 93. The threaded column 91 is threadedly connected to the lower part of the bending plate 1. The rotating ring 92 is fixedly sleeved on the upper end of the threaded column 91. The connecting block 93 is fixedly connected to the bottom end of the threaded column 91 and is fixedly connected to the upper side of the arch rod 81. Since the required arching angle is different for different film separation positions, in order to facilitate the fixing of the film separation position, the rotating ring 92 is rotated to drive the threaded column 91 to rotate, thereby adjusting the bending of the arch rod 81 and the bending plate 1, and adjusting the required film separation angle.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
