Description

Technical Field

[0001] The utility model relates to the technical field of building support structures, in particular to a novel flexible support. Background Art

[0002] The building roof and columns use inclined supports to form a space truss to enhance the rigidity and earthquake resistance of the building structure. At present, the roof support and column support of steel structure buildings mostly use round steel supports, such as Figures 14 to 16 As shown, this round steel support has a long hole on the web of the steel beam or steel column, and two semicircular support connecting plates are welded outside the long hole. The two ends of the round steel support are respectively processed with threads. The end of the round steel support is passed through the long hole and over the arc surface of the support connecting plate, and the tensioning nuts are screwed into the two ends respectively. The round steel support is held between the support connecting plates at the two ends by the tensioning nuts; the tensioning nuts are continued to be tightened to tension the round steel support. The round steel support forms a reinforcement effect between the two structural members with its tensile effect. When this type of round steel support is used as an inter-column support, a round steel with a diameter of 25mm is generally used. When used as a horizontal support for the roof, a round steel with a diameter of 20mm or 25mm is generally used. The round steel support uses a large amount of steel and has a large weight. Therefore, the sagging amount in the middle is large, and it is difficult to achieve ideal tensioning, which will affect its tensile effect; in addition, due to the influence of its own large rigid deformation, the force performance after installation often does not meet the design requirements. For this reason, the support structure needs to be improved to improve the above situation. Utility Model Content

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0034] Embodiment 1: Figures 1 to 4 As shown together, a new type of flexible support is used for holding between two structural members 1 of a building, including a steel strand 2, and strand connection structures are respectively provided between the two ends of the steel strand 2 and the structural member 1 at the corresponding ends, and at least one of the strand connection structures is an adjustable connection structure 3 for tensioning the steel strand 2; the adjustable connection structure 3 includes a threaded adjustment member 4, one end of the threaded adjustment member 4 is provided with a first strand connection portion 5 for connecting to the steel strand 2, and an end limit portion 6 is provided between the other end of the threaded adjustment member 4 and the structural member 1.

[0035] When one end of the threaded adjustment member 4 is positioned and restricted by the end limiter 6, the threaded adjustment member 4 is rotated in the spiral direction, so that the first stranded wire connection portion 5 moves closer to the end limiter 6, thereby achieving the tensioning of the steel strand 2. Accordingly, as long as the adjustable connection structure 3 is set between one end of the steel strand 2 and the corresponding end of the structural member 1, the tensioning operation can be performed. In this embodiment, both of the stranded wire connection structures are adjustable connection structures 3 for illustration.

[0036] like Figure 2 and Figure 4 As shown, the threaded adjustment member 4 of this embodiment includes an adjustment screw 41, a holding hole 42 is penetrated on the structural member 1, and holding support plates 43 are fixedly provided on both sides of the holding hole 42 away from one end of the steel strand 2 on the structural member 1, and an adjustment nut 44 is installed on the end of the adjustment screw 41 passing through the holding hole 42 and crossing the holding support plate 43, and the adjustment nut 44 is arranged against the holding support plate 43. In the process of rotating the adjustment nut 44, the adjustment screw 41 drives the first strand connection part 5 to move toward the end limit part 6, thereby realizing the tensioning operation.

[0037] Here, since the adjusting nut 44 is restricted by the holding support plate 43 , the end of the threaded adjusting member 4 is positioned and restricted at the structural member 1 , and thus the holding support plate 43 and the adjusting nut 44 also serve as the end restriction portion 6 .

[0038] The first stranded wire connection part 5 includes a first winding body 51 for winding the steel stranded wire 2, and the end of the steel stranded wire 2 winding around the first winding body 51 is fixedly connected to the straight section of the steel stranded wire 2. The adjusting screw 41 of this embodiment can directly use existing tiger head pull rods or die forged eye bolts and other hardware. The structures using the two kinds of hardware are respectively as follows: Figure 4 and Figure 2As shown, under the condition of reducing the cost of parts, the annular structures on these hardware parts can be directly used as the first winding body 51. Of course, the adjusting screw 41 can also be a U-shaped bolt, that is, in this case, there are two adjusting screws 41, and the curved part on the U-shaped bolt constitutes the first winding body 51. Of course, in this case, two sets of the holding holes 42 should be provided on the structural member 1, and the adjusting nuts 44 on the two adjusting screws 41 are both tensioned and adjusted.

[0039] After the steel strand 2 passes around the first winding body 51, the fixed connection between the steel strand 2 and the straight line segment can be achieved by: Figure 2 The cable clamp 21 shown in the figure can also be clamped and fixed by Figure 4 The iron wire 22 shown is wound and tied to fix, or both are used together. If necessary, a lining ring 8 can be added between the steel strand 2 and the first winding body 51, such as Figure 2 As shown, to reduce the wear of the steel strand 2.

[0040] In this embodiment, the steel strand 2 replaces the round steel support, and the tensile strength of the steel strand 2 can reach 1570Mpa, which is stronger than the tensile strength of the round steel support of only 210Mpa. Accordingly, under the condition of having the same tensile force, the amount of steel used in the steel strand 2 is much lower than that in the round steel support. The steel strand 2 is a flexible structure, and its small weight and the characteristics of not being prone to rigid deformation make it easier to tension the steel strand 2 to meet the expected tensile requirements; at the same time, the connection form between the steel strand 2 and the structural member 1 is easy to form a variety of forms, and the application is flexible, which is convenient for selection according to different application scenarios. In actual application, multiple embodiments of this embodiment can be arranged between the two structural members 1 according to actual needs. For example, for the use of holding between roof beams and other columns, it is preferred to hold two of the steel strands 2 between the two structural members 1, and the two steel strands 2 are arranged crosswise.

[0041] Embodiment 2: Figure 5 As shown, the main difference between this embodiment and the first embodiment is that the threaded adjustment member 4 includes an adjustment sleeve 45, and the adjustment sleeve 45 is provided with two adjustment threads arranged in opposite spiral directions, and each of the adjustment threads is respectively installed with a connecting screw 46, wherein one of the connecting screws 46 is provided with the first stranded wire connecting portion 5, and the other connecting screw 46 is provided with the end limit portion 6. By rotating the adjustment sleeve 45 relative to the two connecting screws 46, the two connecting screws 46 move closer to each other; and for one of the connecting screws 46 to form a positioning limit on the structural member 1 by relying on the end limit portion 6, it is equivalent to the other connecting screw 46 driving the first stranded wire connecting portion 5 to move closer to the structural member 1, and the steel strand 2 is tensioned.

[0042] The end limiter 6 is hingedly connected to the structural member 1 through the connecting screw 46. The first stranded wire connection part 5 is also implemented by a winding body, and of course the winding body here can also be a ring structure. In actual application, the adjustment sleeve 45 and the two connecting screws 46 can directly use a basket bolt that meets the above usage scenarios, and the first stranded wire connection part 5 is formed by the ring structure of the basket bolt. The use of a hardware such as a basket bolt is also conducive to reducing the parts cost of this embodiment.

[0043] Embodiment 3: Figure 6 As shown, the difference between this embodiment and the first embodiment mainly lies in that: the threaded adjustment member 4 includes two parallel adjusting screws 41, a hooking portion 47 is fixedly provided between the ends of the two adjusting screws 41 away from the steel strand 2, and a U-shaped buckle 48 is hingedly installed on the structural member 1 to form a hooking connection with the hooking portion 47; the two adjusting screws 41 are commonly mounted with the first strand connection portion 5, and an adjusting nut 44 is installed on each adjusting screw 41 on the side of the first strand connection portion 5 close to the steel strand 2.

[0044] The hooking of the hooking portion 47 and the U-shaped buckle 48 forms a positioning restriction of the threaded adjustment member 4 at the structural member 1, so the hooking portion 47 and the U-shaped buckle 48 in this embodiment constitute the end limit portion 6. Under this positioning restriction, by rotating the adjusting nut 44 toward the end limit portion 6, the first stranded wire connection portion 5 can be pushed to move close to the end limit portion 6 to achieve the tensioning of the steel strand 2. In practical application, the two adjusting screws 41 can directly adopt NUT wedge-shaped wire clamps, the arc-shaped portion on which constitutes the hooking portion 47, and the wedge-shaped clamp portion on which constitutes the first stranded wire connection portion 5. The specific use principle of this wedge-shaped clamp portion is: the steel strand 2 passes through the wedge-shaped hole and then bypasses the wedge-shaped clamp block, and then passes back through the wedge-shaped hole to form a fixed connection with the straight section. In the process of tensioning the steel strand 2 by the first stranded wire connection portion 5, the steel strand 2 wound on the wedge-shaped clamp block will be squeezed more and more tightly between the wedge-shaped clamp block and the wedge-shaped hole to form a reliable connection. This principle is easy to understand by those skilled in the art in combination with the use principle of NUT wedge wire clips, and will not be described in detail here. The use of common hardware such as NUT wedge wire clips is also conducive to reducing parts costs.

[0045] Embodiment 4: Figure 7 As shown, the difference between this embodiment and embodiment 1 mainly lies in that one of the stranded wire connection structures is an adjustable connection structure 3, and the other stranded wire connection structure is a non-adjustable connection structure 7, that is, the tensioning of the steel strand 2 is achieved by performing a tensioning operation at one end.

[0046] like Figures 8 to 12As shown, the non-adjustable connection structure 7 in this embodiment includes a second connection member 71 hingedly connected to the structural member 1, and a second winding body 72 is provided on the second connection member 71. The end of the steel strand 2 passes around the second winding body 72 and is fixedly connected to the straight section of the steel strand 2.

[0047] The second connecting member 71 can be directly implemented by using common hardware such as existing U-shaped shackles, tiger head connecting members or NX wedge-shaped wire clips. When a U-shaped shackle or tiger head connecting member is used, Figures 8 to 11 As shown, the bent connecting portion constitutes the second winding body 72. When the NX wedge line card is used, as shown in FIG. Fig.12 As shown, the steel strand 2 is also connected by winding around the wedge-shaped block and then extruding the wedge-shaped block and the wedge-shaped hole. This is the same as the connection method of the steel strand 2 on the NUT wedge wire clamp, which is easy to understand for those skilled in the art and will not be repeated here.

[0048] Of course, a lining ring 8 can also be added between the steel strand 2 and the second winding body 72 to reduce the wear of the steel strand 2. The steel strand 2 is fixedly connected to the straight section after winding, such as Figures 8 to 12 As shown, it can also be realized by using one or more of the following: a steel cable clamp 21, a wire 22 winding, and a steel sleeve 23 extrusion clamping. This embodiment also directly uses common hardware, which is also conducive to reducing the cost of parts.

[0049] Embodiment 5: Fig.13 As shown, the difference between this embodiment and the fourth embodiment is mainly that: the non-adjustable connection structure 7 includes a second connection member 71 hingedly connected to the structural member 1, the second connection member 71 is provided with a second winding body 72, the steel strand 2 is wound with a pre-twisted wire 24, and the pre-twisted wire 24 is arranged around the second winding body 72. The pre-twisted wire 24 is used to form a winding connection, and the pre-twisted wire 24 is wound, squeezed and clamped on the straight section of the steel strand 2 to achieve an equal strength connection.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the description only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements. For example, the adjustable connection structure 3 and the non-adjustable connection structure 7 of the present embodiment disclose a variety of wrapping connection methods, and these wrapping connection methods can be used in the adjustable connection structure 3 and the non-adjustable connection structure 7 in an equivalent manner. In addition, the adjustable connection mechanism 3 and the non-adjustable connection structure 7 can also be used in different combinations, etc. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the present utility model is defined by the attached claims and their equivalents.
