Description

Technical Field

[0001] The present application relates to the technical field of tensioned membranes, and in particular to a connection structure of a gutter and a tensioned membrane. Background Art

[0002] Tensile membrane is a form of building structure, also known as membrane structure or stretched membrane structure. It is made of high-strength thin film materials and reinforcing components. A certain pre-tensioning stress is generated inside it in a certain way to form a certain spatial shape. It serves as a covering structure and can withstand certain external loads.

[0003] ETFE membrane is a commonly used tensile membrane material with high tensile strength, impact strength and tear resistance, and can withstand greater pressure and resist external impact. It is widely used in various tensile membrane structures, such as the roofs and walls of buildings such as stadiums, exhibition centers and conference centers. When the tensile membrane is applied to the roof, the tensile membrane can cooperate with the gutter on the roof. The tensile membrane is set on both sides of the gutter, so that rainwater falling on the tensile membrane can flow into the gutter through the tensile membrane and then be discharged through the drainage system.

[0004] The gutter is usually set on the main beam of the roof, and the main beam is provided with ear plates, and the gutter is placed on the ear plates; the tensile membrane is located on both sides of the top of the gutter, and the tensile membrane on each side is connected to one side of the ear plate through a tensioning member; the tensile membrane is a flexible structure, and under the action of wind load or snow load, the tensile membrane will deform. Under the tension of the tensile membrane, the tensile membrane easily causes the ear plates on both sides to bend to the side away from each other, affecting the stability of the structure.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] The embodiment of the present application discloses a connection structure between a gutter and a tension membrane. Figure 1 and Figure 2 The connection structure of the gutter and the tensile membrane includes a main beam 1, an ear plate 2, a gutter 3 and a tensile membrane 4. There are multiple main beams 1, which are located at the roof. The bottom of the main beam 1 is fixedly connected to a support beam, which is vertically arranged; multiple main beams 1 are staggered to form multiple grids, and a tensile membrane 4 is arranged in each grid. The ear plate 2 is fixedly connected to the main beam 1, and there are multiple ear plates 2, which are evenly spaced along the length direction of the main beam 1. The ear plate 2 includes a connecting portion 21 and a limiting portion 22, and the connecting portion 21 is welded to the top surface of the main beam 1; the limiting portion 22 is fixedly connected to the top surface of the connecting portion 21, and there are two limiting portions 22, which are symmetrically arranged at both ends of the connecting portion 21; the two limiting portions 22 are arranged at intervals, and the spacing between the two limiting portions 22 is the same as the width of the gutter 3, so the gutter 3 can be installed between the two limiting portions 22.

[0037] Reference Figure 1 , a connecting plate 8 is provided on the side where the two limiting parts 22 are close to each other, and a mounting groove 221 is provided on the limiting part 22, and the connecting plate 8 is welded in the mounting groove 221; the connecting plate 8 is arranged along the length direction of the gutter 3, and the connecting plate 8 can fix and connect multiple ear plates 2 together to form a whole, which helps to enhance the integrity. In addition, the two side walls of the gutter 3 are respectively welded and fixed to the two connecting plates 8, and the connecting plates 8 can increase the contact area between the ear plates 2 and the gutter 3, thereby improving the stability of the gutter 3.

[0038] Reference Figure 1 and Figure 3The tension membrane 4 is located above the gutter 3, and each gutter 3 is located at the edge of the tension membrane 4, so that rainwater on the tension membrane 4 can easily flow into the gutter 3. A tensioning assembly 6 is provided at the edge of the tension membrane 4, and the tensioning assembly 6 can tighten and fix the edge of the tension membrane 4. The process of tightening the tension membrane 4 will cause a certain tension to the limit part 22. In order to reduce the impact on the limit part 22, a reinforcing plate 5 is welded between the two connecting plates 8; a plurality of reinforcing plates 5 are provided, and the number of reinforcing plates 5 is the same as the number of ear plates 2, and each reinforcing plate 5 corresponds to one ear plate 2.

[0039] Reference Figure 4 The tensioning assembly 6 includes a fixing member 61, a tensioning bolt 62 and a tensioning nut 63. The fixing member 61 is an aluminum profile, and is arranged along the length direction of the gutter 3; the fixing member 61 is located between the two limiting parts 22, and the fixing member 61 is located above the reinforcing plate 5. A receiving groove 611 is provided on the fixing member 61 along its own length direction, and a connecting rod 9 is slidably inserted into the receiving groove 611. A sleeve is prefabricated at the edge of the tensioning membrane 4. When installing, the connecting rod 9 is first inserted into the sleeve, and then the connecting rod 9 is hot-melted and connected to the sleeve, so that the connecting rod 9 and the tensioning membrane 4 are fixedly connected; then the connecting rod 9 is inserted into the receiving groove 611, and the movement of the connecting rod 9 can be limited, thereby limiting the edge of the tensioning membrane 4. An avoidance groove 612 is also provided on the fixing member 61 along its own length direction; the head of the tensioning bolt 62 is located in the avoidance groove 612, and the end of the tensioning bolt 62 away from the head passes through the reinforcing plate 5. The tensioning nut 63 is threadedly connected to one end of the tensioning bolt 62 passing through the reinforcing plate 5, and the tensioning nut 63 abuts against the reinforcing plate 5. Therefore, it is only necessary to limit the rotation of the tensioning bolt 62 and then rotate the tensioning nut 63 to move the tensioning bolt 62 toward the side close to the reinforcing plate 5, thereby moving the fixing member 61 toward the side close to the reinforcing plate 5, and the fixing member 61 drives the edge of the tensioning membrane 4 to move, thereby tensioning the edge of the tensioning membrane 4.

[0040] Reference Figure 5 A cable 7 is also fixedly connected to the ear plate 2 through a pin shaft, and both ends of the cable 7 are respectively connected to the ear plates 2 on the two main beams 1, and the cable 7 is located below the tensioning membrane 4; a cable sleeve 41 is hot-melt-bonded on the bottom side of the tensioning membrane 4, and a plurality of cable sleeves 41 are provided and evenly spaced, and each cable 7 passes through a cable sleeve 41, so the cooperation of the cable sleeve 41 and the cable 7 can reduce the influence of wind force on the tensioning membrane 4.

[0041] Reference Figure 4The end of the fixing member 61 away from the tension bolt 62 is clamped with an elastic pad 10, which is a rubber pad. The elastic pad 10 and the tension membrane 4 are against each other, so the possibility of the fixing member 61 scratching the tension membrane 4 can be reduced, thereby ensuring the normal use of the tension membrane 4. In addition, a rubber pad is also provided at one end of the connecting plate 8 close to the tension membrane 4. The rubber pad on the connecting plate 8 and the tension membrane 4 are against each other, so the tension membrane 4 can be further protected.

[0042] The implementation principle of Example 1 is as follows: during construction, the ear plates 2 are first welded to the top surface of the main beam 1 in sequence; then the connecting plate 8 is placed in the mounting groove 221 of the ear plate 2, and the connecting plate 8 and the ear plate 2 are welded and fixed; then the gutter 3 is placed on the top surface of the ear plate 2 so that the gutter 3 is located between the two connecting plates 8, and the outer wall of the gutter 3 and the connecting plate 8 are welded and fixed; then the reinforcing plates 5 are welded to the corresponding ear plates 2 in sequence, and the reinforcing plates 5 are located above the gutter 3 to enhance the strength of the ear plates 2; then the fixing members 61 are slid into the connecting rods 9 at the edge of the tensioning membrane 4 in sequence, and then the fixing members 61 are placed above the reinforcing plates 5, and the heads of the tensioning bolts 62 are slid into the avoidance grooves 612 of the fixing members 61, and then the tensioning bolts 62 are inserted into the reinforcing plates 5, and the tensioning nuts 63 are screwed in; the fixing members 61 can be moved downward by moving the tensioning bolts 62 and rotating the tensioning nuts 63, thereby gradually tightening the edge of the tensioning membrane 4 and fixing the tensioning membrane 4. Then the cable 7 is passed through the cable sleeve 41 , and both ends of the cable 7 are fixedly connected to the ear plate 2 , so as to further restrict the tension membrane 4 .

[0043] Example 2

[0044] Reference Figure 6 and Figure 7 The difference between this embodiment and the first embodiment is that in this embodiment, a positioning block 11 is welded on the side of the connection part 21 away from the limiting part 22. Two positioning blocks 11 are provided and are arranged in parallel at intervals. The spacing between the two positioning blocks 11 is the same as the width of the main beam 1. Therefore, after the ear plate 2 is placed on the top surface of the main beam 1, the two positioning blocks 11 are respectively fitted with the two side walls of the main beam 1, which can limit the movement of the ear plate 2, thereby reducing the possibility of the ear plate 2 being installed skewed, and helping to arrange multiple ear plates 2 neatly, so as to facilitate the installation of the gutter 3 on the ear plate 2. After the ear plate 2 is placed at the desired installation position on the main beam 1, the ear plate 2 is welded to the main beam 1, and then the gutter 3 and the tension membrane 4 can be installed.

[0045] Furthermore, a guide block 12 is welded to the end of the positioning block 11 away from the connecting portion 21. The guide block 12 is arranged in an arc shape, and the ends of the two guide blocks 12 away from the connecting portion 21 are bent toward a side away from each other, so that the guide block 12 can play a guiding role, making it convenient to quickly install the ear plate 2 on the main beam 1.

[0046] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
