Abstract
Description
Technical Field
[0001] This utility model relates to the field of membrane installation, and in particular to a membrane high-altitude installation positioning and pre-tightening device. Background Technology
[0002] As a lightweight, high-strength, and corrosion-resistant new type of building material, membrane materials are widely used in high-altitude operation scenarios such as large stadiums, sunshades, and landscape architecture. During the high-altitude installation of membrane materials, precise positioning and uniform pre-tightening force are key to ensuring structural stability and service life.
[0003] Positioning deviations during membrane installation can lead to uneven stress on the membrane, causing localized tearing or overall deformation. Insufficient pre-tensioning can cause the membrane to sway under external forces such as wind, affecting safety. Therefore, achieving high-altitude positioning and pre-tensioning of the membrane is crucial. However, traditional membrane installation devices have shortcomings in practical use.
[0004] A search revealed Chinese Patent Publication No. CN218715270U, which discloses a membrane-pulling tool for membrane installation. The tool includes a membrane-pulling body for clamping the membrane material. The body comprises a lower clamping plate, an upper clamping plate that cooperates with the lower clamping plate, and a hook on the lower clamping plate. The membrane material is placed between the lower and upper clamping plates. A fixing bolt perpendicular to the lower clamping plate is fixedly installed on the lower clamping plate. A through hole corresponding to the fixing bolt's position is provided on the upper clamping plate for the fixing bolt to pass through. A nut is fitted onto the fixing bolt to lock the upper and lower clamping plates. The hook is U-shaped, with both ends welded and fixed to the upper surface of the lower clamping plate, and the bend protruding outside the lower clamping plate. It is used to connect a tensioner. The advantages are that it not only achieves membrane tensioning but also facilitates installation and disassembly, and the membrane material is not easily damaged.
[0005] Although the device has some improvements, it still has shortcomings in actual use. The device only uses raised ribs, upper clamping plates, and lower clamping plates to clamp and fix the membrane material. During the membrane tensioning process, insufficient friction on the contact surfaces can easily lead to slippage, affecting the pre-tensioning and positioning effects. In addition, the membrane material area is often large during installation, and the installation frame is generally pre-built and fixed in position. When using the device, it is impossible to accurately match the position and spacing of the membrane material fixing and tensioning with the position of the installation frame. This means that during installation, tools such as measuring tapes are still needed to adjust the distance, which is quite troublesome.
[0006] To address this issue, a high-altitude installation positioning and pre-tightening device for membrane materials is proposed. Utility Model Content
[0007] To overcome the above shortcomings, this utility model provides a membrane material high-altitude installation positioning and pre-tightening device, which aims to improve the problems in the prior art where the membrane material is easily slipped due to insufficient friction during clamping, affecting the pre-tightening effect, and the fixed tensioning position is difficult to match with the installation frame spacing, causing inconvenience.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a membrane material high-altitude installation positioning and pre-tightening device, including a fixing block 1 connecting the overall device. The right surface of the fixing block 1 is provided with a fixing component for clamping and fixing the membrane material, and the left surface of the fixing block 1 is provided with a positioning mechanism for positioning the fixing component. The positioning mechanism can intuitively understand the distance difference between the fixing components clamping the membrane material surface at different positions, and can intuitively understand the spacing between adjacent fixing components to meet actual needs. It can pre-position the membrane material to meet subsequent high-altitude installation requirements.
[0022] Reference Figure 1 - Figure 2 The fixing assembly includes a clamping plate 21 for holding the membrane material, which is fixedly connected to the bottom end of the right surface of the fixing block 1. An I-beam 25 is slidably connected to the inner surface of the fixing block 1, and the I-beam 25 slides longitudinally. A square opening is provided on the upper surface of the fixing block 1. A clamping plate 22 for holding the membrane material is fixedly connected to the right surface of the I-beam 25. A baffle 23 for positioning the membrane material is fixedly connected to the right surface of the clamping plate 22. The baffle 23 can press the membrane material tightly to prevent slippage. The lower surface of the clamping plate 22 and the upper surface of the clamping plate 21 are both fixedly connected with anti-slip devices to prevent the clamped membrane material from loosening and slipping. Block 24, the anti-slip block 24 is made of rubber, which can enhance the friction of clamping the membrane material and prevent damage to the membrane material. The upper surface of the I-shaped block 25 has a through-hole for mounting, and the upper surface of the fixing block 1 has a through-hole for round hole. The mounting hole and the round hole are aligned. The inner wall of the mounting hole is threaded with a fixing element 26 for adjusting the relative position of the fixing block 1 and the I-shaped block 25. The fixing element 26 consists of a fixing bolt and a nut, which can cooperate with each other. In use, it is screwed into the round hole and the mounting hole, and then the nut is tightened to bring the fixing block 1 and the I-shaped block 25 closer together, thereby clamping and fixing the membrane material.
[0023] Reference Figure 1 - Figure 2 The anti-slip blocks 24 on the lower surface of clamping plate 22 and the anti-slip blocks 24 on the upper surface of clamping plate 21 are staggered left and right, which can ensure that the membrane material can be clamped and ensure stability. The fixing member 26 penetrates the lower surface of the fixing block 1.
[0024] Reference Figure 1 , Figure 3 , Figure 4 The positioning mechanism includes a connecting component for intuitively understanding the distance between two adjacent sets of fixed components. The connecting component includes a connecting plate 31, which is fixedly connected to the left surface of the fixed block 1. The inner wall of the connecting plate 31 is elastically connected to a winding drum 32 via a torsion spring 38. The inner wall of the connecting plate 31 has a cavity, and the winding drum 32 is located in the cavity. One end of a connecting rope 33 is fixedly connected to the outer wall of the winding drum 32. The surface of the connecting rope 33 is marked with a scale to facilitate the operator in judging the length of the connecting rope 33 pulled out. The other end of the connecting rope 33 is fixedly connected to an insert block 34, which is located outside the winding drum 32. A slot 35 is provided on the rear surface of the connecting plate 31. The insert block 34 and the slot 35 fit together. The slot 35 penetrates the upper surface of the connecting plate 31. The inner wall of the front side of the connecting plate 31 is elastically connected to a locking block 37 for positioning the insert block 34 via an elastic element 36.
[0025] Reference Figure 1 , Figure 3 , Figure 4 The connecting rope 33 passes through the front surface of the connecting plate 31. The insert 34 is inserted into the inner wall of the slot 35. The insert 34 can be inserted into the slot 35 from top to bottom. During the insertion process, it will squeeze the locking block 37. The rear end of the locking block 37 is set as an arc surface. When the arc surface is continuously squeezed by external force, the locking block 37 will move forward and retract into the connecting plate 31 and disengage from the slot 35 to release the obstruction. The locking block 37 is slidably connected to the inner wall of the fixing block 1. When the locking block 37 moves forward, it will squeeze the elastic element 36 to generate a reaction force. The locking block 37 is locked above the slot 35. The winding drum 32 is rotatably connected to the inner wall of the connecting plate 31. When the connecting rope 33 is pulled, the winding drum 32 will rotate. During this process, the torsion spring 38 will be squeezed to generate a reaction force.
[0026] Reference Figure 1 , Figure 3 , Figure 5 The positioning mechanism also includes a limiting component for limiting the winding drum 32. The limiting component includes a pull ring 41, which is slidably connected to the upper surface of the connecting plate 31. The pull ring 41 is easy to pull. A limiting plate 42 is fixedly connected to the lower surface of the pull ring 41. A limiting block 43 is fixedly connected to the lower surface of the limiting plate 42. The pull ring 41, the limiting plate 42, and the limiting block 43 will move synchronously. A limiting groove 44 is opened on the upper surface of the winding drum 32. Multiple sets of limiting grooves 44 are opened, all of which fit with the limiting block 43 and are corresponding in position. The upper surface of the limiting plate 42 is elastically connected to the inner wall of the top of the connecting plate 31 through an elastic element 45. When the limiting plate 42 moves upward, it will squeeze the elastic element 45 to generate a reaction force.
[0027] Reference Figure 1 , Figure 3 , Figure 5The limiting block 43 is inserted into the inner wall of the limiting groove 44. The bottom edge of the limiting block 43 is chamfered to facilitate its insertion into the limiting groove 44. When the limiting block 43 is inserted into the limiting groove 44, it will limit the winding drum 32. The center of the pull ring 41, the limiting plate 42, and the winding drum 32 are on the same axis, which can ensure that the movement is stable.
[0028] Working principle: Place the edge of the membrane material to be installed on clamping plate 21. At this time, the edge of the membrane material is located between clamping plate 21 and clamping plate 22. The sliding I-beam block 25 drives clamping plate 22 to move downward until the anti-slip block 24 on clamping plate 21 and clamping plate 22 are in close contact with the membrane material.
[0029] Then, use fixing bolts to pass through the round hole of fixing block 1 and the mounting hole of I-block 25, and use nuts to fix them to complete the clamping and fixing of the membrane material, which facilitates the subsequent positioning and pre-tightening of the membrane material.
[0030] When positioning the membrane material, multiple fixing components can be used to clamp different positions on the membrane surface for positioning. The specific clamping spacing is determined by the spacing of the subsequent high-altitude installation frame. During adjustment, first pull the pull ring 41 upward, which will drive the limiting plate 42 and the limiting block 43 to move upward. The upward-moving limiting plate 42 will squeeze the elastic element 45 to generate a reaction force, and the upward-moving limiting block 43 will disengage from the limiting groove 44 to release the limitation on the winding drum 32. Then, pull the insert block 34 to drive the connecting rope 33. When the connecting rope 33 is pulled, it will drive the winding drum 32 to rotate and squeeze the torsion spring 38 to generate a reaction force. The length of the connecting rope 33 pulled out can be determined by observing the scale on the surface of the connecting rope 33. When the length of the connecting rope 33 pulled out is appropriate, stop pulling and hold the part of the connecting rope 33 pulled out by hand. Then, release the pull ring 41 and pull the connecting rope 33 slightly until... When the limiting block 43 and the nearest limiting groove 44 are aligned, the elastic element 45 will push the pull ring 41, the limiting plate 42 and the limiting block 43 to move downward. The limiting block 43 will insert into the limiting groove 44 to limit the winding drum 32 and ensure the stability of the position. Then, the insert block 34 will be inserted into the slot 35 on another set of connecting plates 31. During the insertion process, the insert block 34 will squeeze the arc surface of the locking block 37. The locking block 37 will retract into the connecting plate 31 and disengage from the slot 35 to release the limitation. It will also squeeze the elastic element 36 to generate a reaction force. When the insert block 34 is inserted into the position, the elastic element 36 will push the locking block 37 to lock above the insert block 34 and limit the insertion block 34. Then, the positioning and pre-tightening devices at different positions can be tightened using a pull rope or other existing tightening devices to achieve pre-tightening and pre-positioning. During subsequent installation, the positioning and pre-tightening devices can be directly fixed on the mounting frame to achieve membrane material fixation.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
