[0001] This invention relates to the field of building construction technology, specifically to a curved reticulated shell temporary support frame structure. Background Technology

[0002] Currently, curved reticulated shell structures have been applied and developed unprecedentedly both domestically and internationally. Their structure has advantages such as beautiful shape, reasonable stress distribution, high stability, material saving, and applicability to large spans. They are frequently used in building structures, especially in spaces such as halls and interiors, and have a wide range of applications.

[0003] The building structure is usually constructed by multiple horizontal beams in an arc shape, with the beams fixed together by grid shell nodes. Temporary support frames are required during the construction of the building structure. For example, Chinese patent document CN205035902U discloses a large-scale bifurcated column support complex curved grid frame shaft structure.

[0004] However, because the roof of the building is curved, the height of the various support points is inconsistent. Therefore, there is an urgent need for a support frame that can be adjusted in height to accommodate the different support points at different heights from the ground during the construction of the building. Summary of the Invention

[0010] Furthermore, the fastening and positioning component includes a connecting rod fixed to the support base and a conical spike fixed to the bottom of the connecting rod.

[0011] Furthermore, a number of wheels are fixed to the bottom side of the support base, and a lateral handle is provided on the side of the support base.

[0012] Furthermore, the clamping mechanism includes two clamping arms that can be opened and closed relative to each other, a first connecting arm and a second connecting arm that are rotatably connected to the clamping arms, the other end of the first connecting arm being rotatably disposed on the connecting seat, the second connecting arm being rotatably disposed on the lifting seat, and the lifting seat being moved up and down by a cylinder, and a third connecting arm being rotatably connected between the connecting seat and the second connecting arm.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0028] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0029] Referring to Figures 1 to 7, a curved mesh shell temporary support frame structure includes a lifting mechanism 1 and a clamping mechanism disposed on the top side of the lifting mechanism 1.

[0030] The lifting mechanism 1 includes a support base 11, a multi-section tube assembly 12 is sleeved in the top opening of the support base 11, and a driving component 13 for driving the multi-section tube assembly 12 to move up and down is provided in the support base 11. The driving component 13 is a jack.

[0031] The multi-section tube assembly 12 includes multiple sleeves that are sequentially nested together. These sleeves are divided into one initial sleeve 121, three intermediate sleeves 122, and one final sleeve 123 according to their assembly positions. The number of intermediate sleeves 122 can be increased or decreased as needed, and no restrictions are imposed here. Each sleeve is provided with multiple positioning holes 1211 arranged along its length. Positioning elements 1212 pass through the positioning holes 1211, fixing adjacent sleeves together and thus securing the multi-section tube assembly 12 after extension. The positioning elements 1212 include, but are not limited to, those composed of bolts and nuts. In use, the bolts are inserted through the sleeves, and the nuts are tightened at the threaded ends of the bolts.

[0032] Each of the first sleeve 121, the middle sleeve 122, and the last sleeve 123 is fixedly provided with a limiting ring plate 124. The limiting ring plate 124 includes an annular portion 1241 fixedly disposed on the multi-section pipe assembly 12, and a lifting handle 1242 fixedly disposed on the side of the annular portion 1241. The lifting handle 1242 facilitates the extension of the multi-section pipe assembly 12.

[0033] The support base 11 includes a support tube 111. At least three horizontally extending support channel steels 112 are arranged around the bottom of the support tube 111 along its central axis. Each support tube 111 and support channel steel 112 is fixedly connected to a reinforcing rib 113. Preferably, there are four support channel steels 112 to ensure that the support base 11 is stably supported on the ground. An assist handle 1131 is fixedly provided on the reinforcing rib 113.

[0034] Several wheels 15 are fixed to the bottom side of the support base 11, and a lateral handle 16 is provided on the side of the support base 11. Specifically, the wheels 15 have a self-locking function, so that the support base 11 cannot slide when it is supported on the ground.

[0035] The driving component 13 is a jack, and the output end of the jack is pressed against the bottom surface of the first end sleeve 121 by pushing up and down. Choosing a jack as the driving component 13 results in a lower cost compared to other driving devices.

[0036] A fastening fixing member 14 for pre-embedding in the ground is provided on the bottom side of the support base 11. The fastening fixing member 14 includes a connecting rod 141 and a conical spike 142 fixed to the bottom of the connecting rod 141. A sleeve is fixed to the outer end of the support channel steel 112, and the connecting rod 141 is slidably inserted into the inside of the sleeve. One end of the clamping mechanism is fixed to the end sleeve 123, and the other end is used to clamp the crossbeam fixed to the curved mesh shell. As a specific embodiment, one end of the clamping mechanism is a connecting column, which is inserted into the upper end of the end sleeve 123 and fixed by welding or other means. Two embodiments are provided in this invention for the specific structure of the clamping mechanism.

[0037] Referring to Figures 3 and 4, the first embodiment of the clamping mechanism is as follows.

[0038] The clamping mechanism includes two clamping arms 21 that can open and close relative to each other, a first connecting arm 22 and a second connecting arm 23 rotatably connected to the clamping arms 21, the other end of the first connecting arm 22 being rotatably mounted on a connecting seat 25, and the second connecting arm 23 being rotatably mounted on a lifting seat 27. A cylinder 26 pushes the lifting seat 27 to move up and down. A third connecting arm 24 is rotatably connected between the connecting seat 25 and the second connecting arm 23. Thus, the opening and closing of the clamping arms 21 is controlled by the cylinder 26. In this embodiment, the rotatable connection method includes, but is not limited to, hinges.

[0039] Referring to Figures 6 and 7, a second embodiment of the engagement mechanism is as follows.

[0040] The clamping mechanism includes two clamping members 31 that can open and close relative to each other, a first connecting member 32 and a second connecting member 33 rotatably connected to the clamping members 31, and two second connecting members 33 respectively connected to the two clamping members 31 are provided with mutually meshing teeth 331. The clamping mechanism also includes a motor 34 for driving the rotation of the second connecting members 33. Thus, the opening and closing of the clamping members 31 is controlled by the motor 34. The rotatable connection method in this embodiment includes, but is not limited to, hinges.

[0041] The clamping member 31 includes three clamping plates 311 arranged side by side at intervals. This increases the contact area between the clamping member 31 and the crossbeam of the curved reticulated shell, thereby improving the stability of the connection between the clamping mechanism and the crossbeam.

[0042] The clamping mechanism also includes a mounting plate 35, and the first connecting member 32 includes two connecting plates, which are rotatably disposed on both sides of the mounting plate 35. The motor 34 is fixed to one end of the mounting plate 35, and the second connecting member 33 is rotatably disposed on the other end of the mounting plate 35, thereby making the structure of the clamping mechanism compact.

[0043] The lifting mechanism 1 can switch between a working state and a storage state. Figure 1 shows the working state of the lifting mechanism 1, and Figure 2 shows the storage state of the lifting mechanism 1.

[0044] In use, the first step is to move the curved mesh shell temporary support structure of the present invention to the corresponding position on the ground where the support point is projected by pulling the horizontal movement handle 16 and the assist handle 1131. The second step is to hammer the fixing member 14 into the ground to achieve positioning and prevent accidental sliding or tipping of the support frame. The third step is for the user to stand on the lifting device such as the basket, and during the lifting process, the user manually lifts the lowering handle 1242, thereby extending the multi-section tube assembly 12. Each extension of the first end sleeve 121, the middle sleeve 122, and the last end sleeve 123 can be fixed by inserting the positioning member 1212 into the positioning hole 1211, or by binding it to the lifting handle 1242 with a rope. The rope passes around the crossbeam, and pulling the rope extends the multi-section tube assembly 12. The fourth step is to control the clamping mechanism to clamp and fix the crossbeam to the curved mesh shell. Because there is a gap between the positioning holes 1211 between the sleeves of the multi-section pipe assembly 12, the opening of the clamping mechanism cannot always be exactly abutted against the crossbeam. Therefore, the drive unit 13 is required to fine-tune the multi-section pipe assembly so that it can adapt to different crossbeams and ground heights.

[0045] When storing the curved mesh shell temporary support structure of the present invention, first control the clamping mechanism to disengage from the crossbeam of the curved mesh shell, then release the drive component 13, and finally disassemble the positioning component 1212 to achieve storage. After storage, the curved mesh shell temporary support structure of the present invention occupies only a very small space, thereby facilitating the storage and transportation of the curved mesh shell temporary support structure of the present invention. When it is necessary to transport the curved mesh shell temporary support structure of the present invention, the traveling wheels 15 can be installed on the support channel steel 112 to facilitate transportation.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
