Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a fixing clamp and system for adjustable membrane material prestress. Background Technology

[0002] Prestressed membrane structures can achieve column-free large spaces through a tension system, meeting the needs for high transparency and wide field of vision. In addition, the membrane material has a smooth surface, white color, and beautiful shape, so it is widely used in stadiums, exhibition centers, transportation hubs and other scenarios.

[0003] Traditional methods for fixing the edges of prestressed membrane structures often use clamp connections, which involve clamping and fixing the edges of the membrane material with two layers of metal clamps, and then connecting the clamps with bolts or rivets to form continuous edge constraints. However, when using this method to fix the membrane material, it is not easy to control the tension of planar membrane materials that require high prestressing values. Therefore, improvements are needed.

[0004] Based on the above background, the inventors designed an adjustable membrane material prestress fixing clamp and system to solve at least one of the above problems, and hereby file this application. Summary of the Invention

[0005] The purpose of this application is to provide a fixing clamp and system for adjustable membrane prestress, which solves the problem that existing prestressed membranes are fixed with edge bolts or rivets, making it difficult to control the prestress value of planar membranes with high requirements.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] On the one hand, this application provides a fixing clamp for adjustable membrane material prestress, including a clamp body, on which membrane material pulling grooves and locking grooves are provided opposite to each other;

[0008] It also includes a tensioning member that passes through the membrane tensioning groove and can move freely within the membrane tensioning groove, as well as several adjustable locking members with adjustable locking positions. The adjustable locking members are located in the locking slide groove and are slidably connected thereto.

[0009] Optionally, the cross-sectional shape of the tension member is any one of circular, elliptical, or oval.

[0010] The membrane material pulling groove includes a fixing part and an insertion part. The cross-sectional shape of the fixing part is adapted to the cross-sectional shape of the pulling member, and the width of the insertion part is smaller than the width of the pulling member.

[0011] Optionally, both the tensioning member and the fixing part have circular cross-sectional shapes.

[0012] Optionally, the membrane material pulling groove is a through groove, and the pulling member is disposed through the membrane material pulling groove.

[0013] Optionally, the pulling member includes a pulling rod and at least two limiting nuts;

[0014] The pull rod includes a smooth section and two threaded sections fixed at both ends of the smooth section, with two limit nuts threadedly connected to the threaded sections at both ends of the smooth section respectively;

[0015] The smooth section is inserted into the membrane material pulling groove, and the length of the smooth section is greater than the length of the membrane material pulling groove.

[0016] Optionally, the pulling member includes a pulling rod, a limiting nut, and a limiting end fixed to the end of the pulling rod;

[0017] The pull rod includes a smooth section and a threaded section. The threaded section is located at the end of the pull rod away from the limiting end, and the limiting nut is threadedly connected to the threaded section.

[0018] The smooth section is inserted into the membrane material pulling groove, and the length of the smooth section is greater than the length of the membrane material pulling groove.

[0019] Optionally, the adjustable locking component includes a locking bolt and a locking nut, with the locking nut threaded onto the locking bolt and the end of the locking bolt located within the locking groove.

[0020] Optionally, both the membrane material stretching groove and the locking groove are axisymmetric structures, and their axes of symmetry coincide.

[0021] On the other hand, this body provides a fixing system for adjustable membrane prestress, characterized in that it includes a plurality of fixing clamps for adjustable membrane prestress as described above, and a fixing steel plate fixed to the main body of the building.

[0022] The fixed steel plate has several through holes, and the adjustable locking component is connected to the fixed steel plate through the through holes.

[0023] Beneficial effects of the utility model:

[0024] This application designs a clamp body with a membrane tensioning groove and a locking groove. A tensioning element and an adjustable locking element are respectively installed in the membrane tensioning groove and the locking groove. This allows one side of the membrane body to directly enter the membrane tensioning groove, bypass the tensioning element, and then exit the membrane tensioning groove, thus connecting the edge area of ​​the membrane body to the clamp body. The adjustable locking element fixes the clamp body to a fixed steel plate on the building structure, thereby fixing the edge area of ​​the membrane body to the fixed steel plate using the clamp of this embodiment, completing the prestressing tension of the membrane. When prestress adjustment is needed, the adjustable locking element can be directly adjusted. Therefore, the clamp designed in this application can effectively solve the problem that existing prestressed membrane materials are difficult to control when fixed with edge bolts or rivets, especially for planar membrane materials with high prestress requirements.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1:

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a fixing clamp for adjustable membrane prestress, including a clamp body 1, on which membrane tension grooves 11 and locking grooves 12 are provided opposite to each other;

[0036] It also includes a tensioning member 3 that passes through the membrane tensioning groove 11 and can move freely within the membrane tensioning groove 11, and several adjustable locking members 2 with adjustable locking positions. The adjustable locking members 2 are disposed in the locking slide groove 12 and are slidably connected thereto.

[0037] This embodiment has a clamp body 1 with a membrane tensioning groove and a locking groove 12. A tensioning member 3 and an adjustable locking member 2 are respectively provided in the membrane tensioning groove 11 and the locking groove 12, so that one side of the membrane body 4 can be directly inserted into the membrane tensioning groove 11, bypass the tensioning member 3 and then pass out of the membrane tensioning groove 11, so that the edge area of ​​the membrane body 4 can be connected to the clamp body 1. The adjustable locking member 2 can fix the clamp body 1 to the fixed steel plate 5 on the building body 6, so that the edge area of ​​the membrane body 4 is fixed to the fixed steel plate 5 by the fixing clamp of this embodiment, thus completing the prestressing tension of the membrane. When the prestress needs to be adjusted, the adjustable locking member 2 can be directly adjusted. Therefore, the fixing clamp designed in this application can effectively solve the problem that the existing prestressed membrane materials are fixed by edge bolts or rivets, which is not easy to control for planar membrane materials with high prestress requirements.

[0038] In this embodiment, the cross-sectional shape of the pulling member 3 and the fixing part 111 is circular. In some embodiments, the cross-sectional shape of the pulling member 3 and the fixing part 111 may also be elliptical or oval.

[0039] The membrane material pulling groove 11 includes a fixing part 111 and an insertion part 112. The cross-sectional shape of the fixing part 111 is adapted to the cross-sectional shape of the pulling member 3. The width of the insertion part 112 is smaller than the width of the pulling member 3, so as to prevent the pulling force of the membrane material body 4 from pulling the pulling member 3 out radially from the fixing part 111.

[0040] In this embodiment, the membrane material pulling groove 11 is a through groove, and the pulling member 3 is provided through the membrane material pulling groove 11. The membrane material pulling groove 11 is set as a through groove to facilitate the installation of the pulling member 3 and the insertion of the membrane material body 4.

[0041] In this embodiment, the pulling member 3 includes a pulling rod 31, a limiting nut 33, and a limiting end 32 fixed to the end of the pulling rod 31;

[0042] The pull rod 31 includes a smooth section 311 and a threaded section 312. The threaded section 312 is located at the end of the pull rod 31 away from the limiting end 32, and the limiting nut 33 is threadedly connected to the threaded section 312.

[0043] The smooth section 311 is inserted into the membrane material pulling groove 11, and the length of the smooth section 311 is greater than the length of the membrane material pulling groove 11, so as to avoid the thread structure of the threaded section 312 from causing compression damage to the membrane material during the pulling process of the membrane material body 4.

[0044] In this embodiment, the connection between the membrane body 4 and the clamp body 1 mainly relies on the smooth section 311 of the pull rod 31 to press the edge area of ​​the membrane body 4 into the fixing part 111, thereby realizing the connection and fixation between the membrane body 4 and the clamp body 1.

[0045] In some embodiments, technicians may also provide frosted texture on the surface of the smooth section 311 of the tension member 3 as needed to increase the friction coefficient of the smooth section 311, thereby improving the stability of the membrane body 4 after it is pressed by the smooth section 311 of the tension member 3.

[0046] In this embodiment, the adjustable locking component 2 includes a locking bolt 21 and a locking nut 22. The locking nut 22 is threaded onto the locking bolt 21, and the end of the locking bolt 21 is located in the locking groove 12.

[0047] In this embodiment, both the membrane material pulling groove 11 and the locking slide groove 12 are axisymmetric structures, and their axes of symmetry coincide. This makes the pulling member 3 exert a more balanced and stable squeezing force on the membrane material body 4 after the membrane material body 4 is inserted into the locking slide groove 12, thereby improving the stability of the connection between the membrane material body 4 and the clamp body 1.

[0048] Example 2:

[0049] like Figure 3As shown, this embodiment provides a fixing system for adjustable membrane prestress, characterized in that it includes a plurality of fixing clamps for adjustable membrane prestress as described above, and a fixing steel plate 5 fixed to the building body 6;

[0050] The fixed steel plate 5 is provided with several through holes (not shown in the figure), and the adjustable locking member 2 is connected to the fixed steel plate 5 through the through holes.

[0051] The remaining structures of this embodiment are the same as those of Embodiment 1 above, and will not be described again here.

[0052] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
