Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically to a device for erecting a hyperboloid support frame. Background Technology

[0002] As the main longitudinal load-bearing structure in building construction, columns are of paramount importance, and their structural and supporting performance directly determines the safety of the overall building. Among all types of columns, hyperboloid columns are often used as supporting structures for buildings with large horizontal projected areas and where aesthetics are a requirement, due to their superior structural and supporting performance, ability to reduce local pressure at the support points, and high aesthetic appeal.

[0003] Because the overall volume of the support column is large, it is generally prepared by making multiple identical hyperboloid units and then splicing them together to form a hyperboloid support column. Each hyperboloid unit is an uneven plate-shaped material with a certain thickness, and its shape is difficult to control. Therefore, it is generally prepared by casting.

[0004] The casting process requires the pre-construction of a base frame containing molds and shaping mechanisms to form an ideal hyperboloidal panel-shaped casting cavity. The conformity and smoothness of the surface shape of the casting cavity directly determine the overall conformity and smoothness of the hyperboloidal support formed by the casting. The mold is built based on the shaping mechanism, which, as the structural support of the mold, directly determines the conformity and smoothness of the surface shape of the casting cavity.

[0005] Existing molds generally use a back mold, a front mold, and side molds to form the casting cavity. The back mold and the front mold are both integral hyperboloid plates, which need to be processed and prepared according to the specific hyperboloid dimensions required, resulting in high costs. In addition, steel structures such as scaffolding are generally used to support and shape the back mold and the front mold. However, since the back mold and the front mold are irregular structures, the current steel structures can generally only provide point support and cannot effectively match and support the structure of the back mold and the front mold. During the casting process, the back mold and the front mold bear the weight and pressure of the concrete, which makes them prone to deformation. As a result, the shape conformity and surface performance of the final cast hyperboloid column are not ideal. Summary of the Invention

[0006] The purpose of this invention is to provide a construction device for a hyperboloid column base frame, which solves the problems that the shape conformity and surface performance of the hyperboloid columns cast by existing molds and support shaping mechanisms for casting hyperboloid columns are not ideal, and also solves the problem that the molds used for casting hyperboloid columns are difficult to support stably due to their special shape.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention provides a device for constructing a hyperboloid support frame. By setting a back rib assembly comprising multiple horizontal and vertical ribs, and using a cross-joint method to form a support skeleton, the multiple horizontal ribs provide structural support to the vertical ribs located at different longitudes along different latitudes, effectively improving the structural stability of the vertical ribs. Then, by setting the inner arc of the vertical ribs to a single line shape of the desired hyperbola, the inner arcs of all the spaced vertical ribs can be used to form a highly precise and structurally stable hyperboloid base. Furthermore, by setting a woven layer comprising a shaping layer and a reinforcing layer, the shaping layer includes multiple shaping strips, with the width of the shaping strips being much smaller than their length, and the strips being inclined... A hyperboloid base surface is laid, and the curvature of the shaping strips is effectively regulated along its shape. The elasticity of the shaping strips themselves forms a smooth curved surface, resulting in a tightly sealed hyperboloid shaping surface with extremely high shape conformity. Simultaneously, by fixing the shaping strips to each contacting longitudinal edge, an inclined connection layer is added to the transverse and longitudinal interlocking structure, further enhancing the structural performance and stability of the framework. On this basis, a reinforcement layer consisting of multiple reinforcement strips is added. These reinforcement strips, with a width much smaller than their length, are inclined and intersected with the shaping strips on the hyperboloid shaping surface, thus forming a tightly sealed hyperboloid reinforced surface with extremely high shape conformity. The reinforced strips are cross-bonded with all contacting shaped strips, further enhancing the structural performance and stability of the skeleton while completely forming a tightly sealed hyperboloid reinforced surface with extremely high shape conformity. Based on this, a back mold is set up, consisting of multiple quadrilateral substrates. These quadrilateral substrates are spliced, laid, and bonded to the hyperboloid reinforced surface to form the back mold. The larger substrates effectively conceal the seams between the reinforced strips, minimizing seams while ensuring surface shape conformity, thus further improving surface smoothness. Rivets are used to fasten the edges of the substrates, effectively preventing edge warping. Finally, by setting side molds and a front mold, the final shape is enclosed... The casting cavity is formed by splicing hyperboloid pillars in a trumpet shape. Therefore, it has an invisible inner surface (front mold side) and a visible outer surface (back mold side). Thus, only the shape conformity and smoothness of the outer surface need to be considered to meet the requirements of most scenarios. The back mold has a two-layer support structure of woven layer and back rib assembly. The support structure is surface support and line support, which can effectively ensure the surface shape conformity and surface smoothness of the back mold. Through the cooperation of the above features, the hyperboloid pillar base frame can effectively solve the problem that the shape conformity and surface performance of the hyperboloid pillars produced by existing molds and support and shaping mechanisms for casting hyperboloid pillars are not ideal.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please refer to Figures 1 to 5This invention provides a hyperboloid support frame, comprising: a back rib assembly, the back rib assembly including multiple horizontal ribs 10 and multiple vertical ribs 11, wherein the horizontal ribs 10 are annular plates or arc plates, all of the horizontal ribs 10 are coaxially spaced from top to bottom, and the horizontal ribs 10 are horizontally arranged; the vertical ribs 11 are arc plates, the inner arc of the vertical ribs 11 is a hyperbolic single line, the vertical ribs 11 are vertically arranged, and their outer sides are respectively inserted into all of the horizontal ribs 10 so that the inner side points towards the horizontal ribs. The axis of 10, all the longitudinal edges 11 are spaced apart, so that the inner sides of all the longitudinal edges 11 surround a hyperboloid base surface 1; the second includes a braided layer, the braided layer includes a shaping layer and a reinforcing layer, the shaping layer includes multiple shaping strips 12, the width of the shaping strips 12 is much smaller than its length, the shaping strips 12 are laid obliquely on the hyperboloid base surface 1, all the shaping strips 12 are laid parallel and tightly spliced, so as to form a hyperboloid shaping surface 2 on the hyperboloid base surface 1. The shaping strip 12 is fixedly connected to each of the contacting longitudinal edges 11; the reinforcing layer includes multiple reinforcing strips 13, the width of which is much smaller than its length, and the width of which is greater than the width of the shaping strip 12. The reinforcing strips 13 are laid obliquely on the hyperboloid shaping surface 2, and the reinforcing strips 13 are laid crosswise with the shaping strips 12. All the reinforcing strips 13 are laid parallel and tightly spliced ​​together to form a hyperboloid on the hyperboloid shaping surface 2. The first part includes a reinforced surface 3, wherein the reinforcing strip 13 is fixedly bonded to each of the shaped strips 12 in contact with it; the second part includes a back mold, wherein the back mold includes multiple quadrilateral substrates 20, all of which are tightly spliced, laid and bonded to the hyperboloid reinforced surface 3 to form the back mold, and the edges of the substrates 20 are nailed to the hyperboloid reinforced surface 3 by multiple rivets; the third part includes a side mold 21 and a front mold 22, wherein the side mold 21 and the front mold 22, together with the back mold, form a casting cavity 23.

[0020] The hyperboloid support frame provided in this embodiment, by setting a back edge assembly, includes multiple horizontal edges 10 and vertical edges 11, and constructs a support skeleton using a cross-interlocking method. Multiple horizontal edges 10 provide structural support to the vertical edges 11 located at different longitudes along different latitudes, effectively improving the structural stability of the vertical edges 11. Then, by setting the inner arc of the vertical edges 11 to a single line shape of the desired hyperbola, the inner arc of all the spaced vertical edges 11 can be used to form a highly accurate and structurally stable hyperboloid base surface 1. Based on this, a woven layer is set, including a shaping layer and a reinforcing layer. The shaping layer includes multiple shaping strips 12, and the double-curved surface is laid at an angle using shaping strips 12 with a width much smaller than their length. The curved base surface 1 effectively regulates the curvature of the shaping strip 12 along its shape, and utilizes the elasticity of the shaping strip 12 to form a smooth curved surface, thereby laying a tightly sealed and highly conforming hyperboloid shaping surface 2. Simultaneously, by fixing the shaping strip 12 to each contacting longitudinal edge 11, an inclined connection layer is added to the transverse and longitudinal interlocking structure, further enhancing the structural performance and stability of the skeleton. Based on this, a reinforcement layer including multiple reinforcement strips 13 is provided. These reinforcement strips 13, with a width much smaller than their length, are inclined and intersected with the shaping strip 12 on the hyperboloid shaping surface 2, thereby laying a tightly sealed and highly conforming hyperboloid reinforced surface 3. By cross-bonding the reinforcing strips 13 with all the contacting shaped strips 12, the structural performance and stability of the skeleton are further improved, while a tightly sealed and highly conforming hyperboloid reinforcing surface 3 is formed. Based on this, a back mold is set, comprising multiple quadrilateral substrates 20. These quadrilateral substrates 20 are spliced, laid, and bonded to the hyperboloid reinforcing surface 3 to form the back mold. The larger substrates 20 effectively conceal the seams between the reinforcing strips 13, thereby minimizing seams while ensuring surface conformity and further improving surface smoothness. Rivets are used to fasten the edges of the substrates 20, effectively preventing edge warping. Furthermore, a side mold 2 is set... 1 and the front mold 22 are finally enclosed to form the casting cavity 23. Since the spliced ​​hyperboloid column is trumpet-shaped, it has an invisible inner surface (front mold side) and a visible outer surface (back mold side). Therefore, only the shape conformity and smoothness of the outer surface need to be considered to meet the requirements of most scenarios. The back mold has a two-layer support structure of woven layer and back rib assembly, and the support structure is surface support and line support, which can effectively ensure the surface shape conformity and surface smoothness of the back mold. Through the cooperation of the above features, the hyperboloid column base frame can effectively solve the problem that the shape conformity and surface performance of the hyperboloid column obtained by the existing mold and support shaping mechanism for casting hyperboloid columns are not ideal.

[0021] To further support and limit the front mold 22 and prevent excessive deformation, the hyperboloid support frame also includes an anchoring mechanism. The anchoring mechanism includes multiple anchor rods 24. One end of each anchor rod 24 is perpendicularly connected to the back mold, and the other end passes through the front mold 22. Support members 241 are respectively provided at both ends of the anchor rod 24 located in the casting cavity 23. The end faces of the support members 241 abut against the inner surfaces of the back mold and the front mold 22, respectively. A locking nut 242 is screwed onto one end of the anchor rod 24 that passes through the front mold 22, so that the front mold 22 is clamped between the locking nut 242 and the corresponding support member 241.

[0022] Please Figures 1 to 5 Further reference Figures 6 to 17 The present invention also provides a device for constructing a hyperboloid support frame, comprising: any of the above-mentioned hyperboloid support frame; secondly, a base 30, the base 30 being a horizontally arranged disc shape, the base 30 having multiple radially arranged sliding grooves 31, each of the sliding grooves 31 being slidably connected to a slide block 32, the top of the slide block 32 being vertically provided with a telescopic rod (not shown), the top of the telescopic rod being provided with a connecting seat 33, the connecting seat 33 being detachably connected to the transverse ridge 10; thirdly, a same-diameter mechanism, the same-diameter mechanism being disposed on the base 30, the same-diameter mechanism being able to make all the slide blocks 32 located in all the sliding grooves 31 slide synchronously and with the same diameter.

[0023] With the above setup, the hyperboloid support frame forms a casting cavity 23. Then, a base 30 is set, on which a sliding groove 31 is opened and a sliding block 32 is slidably set. A same-diameter mechanism is set up, which synchronously and with the same diameter drives all the sliding blocks 32 to slide radially along the base 30, thereby adjusting the diameter of the circle where the sliding block 32 is located until it matches the diameter of any horizontal edge 10 of the hyperboloid support frame to provide a support foundation. A telescopic rod is vertically set on the top of the sliding block 32, and a connecting seat 33 is set at the top of the telescopic rod. The telescopic rod is extended or shortened to match the height of the corresponding horizontal edge 10. Then, the connecting seat 33 is fixedly connected to the corresponding horizontal edge 10, thereby providing longitudinal support and lateral limitation for the horizontal edge, thus effectively solving the problem that the mold used for casting hyperboloid supports is difficult to stably support due to its special shape.

[0024] It should be noted that the aforementioned telescopic rod can adopt any telescopic rod structure in the existing technology, such as threaded sleeve rods and hydraulic telescopic rods, as long as it can extend and retract axially and fix its length after extension and retraction. To improve support performance, a jack structure can also be used to adjust the length of the telescopic rod.

[0025] To further explain the specific structure of the equal-diameter mechanism, the equal-diameter mechanism includes a turntable 40 and a guide post 41. The turntable 40 is coaxially rotatably connected to the base 30. The turntable 40 is provided with multiple guide grooves 42, which are involute-shaped around the axis of the turntable 40. All the guide grooves 42 have the same shape and are evenly distributed on the turntable 40. The position of one end of each guide groove 42 near the axis of the turntable 40 can vertically correspond to the inner end of a sliding groove 31. The guide post 41 is vertically disposed at the bottom of the slide 32. When the slide 32 is slidably connected to the sliding groove 31, the guide post 41 can extend into any one of the guide grooves 42 and slide in cooperation. The turntable 40 is driven by a motor 43.

[0026] With the above configuration, the motor 43 drives the turntable 40 to rotate relative to the base 30, thereby driving the involute-shaped guide groove 42 on it to rotate, thereby driving the guide post 41 to move along the guide groove 42, thereby driving the slide block 32 to slide along the slide groove 31.

[0027] Preferably, the side wall of the guide post 41 is provided with a plurality of balls 414; the guide post 41 is slidably connected to the slide block 32 in the vertical direction so that the guide post 41 can be separated from the guide groove 42.

[0028] With the above settings, the smoothness of sliding is improved by the ball bearing 414, and the guide post 41 can slide in the vertical direction. When sliding to the corresponding position, the guide post 41 is moved up, which can stop the influence of the guide groove 42 on the slide block 32, thereby positioning the slide block 32.

[0029] To further fix the adjusted slide block 32 relative to the base 30, the slide block 32 has a hollowed-out center and a vertically installed limiting cylinder 321. The side wall of the limiting cylinder 321 has a pair of positioning holes 322. The upper end of the guide post 41 is located inside the limiting cylinder 321 and is coaxially slidably engaged. The top end of the guide post 41 is hinged with a pair of positioning arms 411. The positioning arms 411 correspond one-to-one with the positioning holes 322 and extend outward from the corresponding positioning holes 322. The extended end of the positioning arm 411 is provided with an elastic block 412. When the guide post 41 rises to separate from the guide groove 42, the positioning arm 411 rotates to the horizontal, and the elastic block 412 contacts and presses against the groove wall of the slide groove 31.

[0030] With the above settings, when the guide post 41 is moved upward, the guide post 41 can be separated from the guide groove 42 to avoid the influence of the guide groove 42 on the slide block 32. The positioning arm 411 can also be opened to make the elastic block 412 contact and squeeze the groove wall of the slide groove 31, thereby using the squeezing force and friction to fix the slide block 32 and the base 30 relatively.

[0031] To enable the guide post 41 to move vertically, a rotating post 413 is rotatably connected to the top of the guide post 41, and the positioning arm 411 is hinged to the rotating post 413. The guide post 41 and the limiting cylinder 321 are slidably connected vertically. A winch 44 is provided above the top of the guide post 41, and the winch 44 is connected to the top of the guide post 41 through two vertically arranged connecting rods 441. The line connecting the two connecting rods 441 passes through the axis of the guide post 41, and the two rods are connected to each other. The connecting rod 441 is centrally symmetrical so that the winch 44 can drive the guide post 41 to rotate at a preset angle to switch between a sliding position and a locked position. When the guide post 41 is in the sliding position, the guide post 41 slides with the guide groove 42, and the elastic block 412 is separated from the groove wall of the sliding groove 31. When the guide post 41 is in the locked position, the guide post 41 is separated from the guide groove 42, and the elastic block 412 contacts and presses against the groove wall of the sliding groove 31.

[0032] In order to support multiple transverse ridges 10 at the same time, all the slide grooves 31 have a disassembly port 311 at one end in the same direction. The slide block 32 is detachably connected to the slide groove 31 through the disassembly port 311. Each slide groove 31 is detachably connected to multiple slide blocks 32, and the number of slide blocks 32 matches the number of transverse ridges 10.

[0033] With the above setup, the slide block 32 can be detached and installed ring by ring. First, install the first ring of slide block 32, and then use the same diameter mechanism to adjust it to the diameter corresponding to the first transverse ridge 10. Then, move the guide post 41 of the slide block 32 upward to fix the slide block 32 relative to the base 30. Then, install the second ring of slide block 32, and again use the same diameter mechanism to adjust it to the diameter corresponding to the second transverse ridge 10. This process is repeated to complete the corresponding support for all transverse ridges 10.

[0034] To further explain the fixed connection structure between the connecting seat 33 and the transverse ridge 10, the top of the connecting seat 33 has a groove 331, the width of which is greater than the width of the transverse ridge 10. The groove 331 is used to embed the transverse ridge 10. A pair of clamping plates 332 are slidably connected within the groove 331. An adjusting screw 333 is screwed through the clamping plates 332. The adjusting screw 333 is rotatably connected to the connecting seat 33. One end is provided with an adjustment handle 334; each clamping plate 332 has a pair of clamping wheels 335 symmetrically arranged on the inner side, the clamping wheels 335 roll horizontally, and the wheel distance of the two clamping wheels 335 of the clamping plate 332 near the axis of the base 30 is smaller than the wheel distance of the two clamping wheels 335 of the other clamping plate 332; the top of the connecting seat 33 is hinged with a locking cover 336, the locking cover 336 can be engaged with the connecting seat 33 to close the groove 331.

[0035] With the above settings, the groove 331 and the locking cover 336 are used to limit the transverse edge 10 longitudinally, the adjusting screw 333 is used to control the clamping plate 332 to limit the transverse edge 10 laterally, and the specific arrangement of the clamping wheels 335 is used to match the arc-shaped structure of the transverse edge 10.

[0036] In order to ensure that the connecting seat 33 can always be connected to the transverse ridge 10, the bottom of the connecting seat 33 is ball-jointed with the top of the telescopic rod.

[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
