The invention provides a clamp for a building support system, which comprises a left clamping part, a right clamping part and a body. Because the left clamping part and the right clamping part clamp the beam body or the column body in a clamping manner, the beam body or the column body cannot be damaged. In addition, the gravity of the hanging object can apply force through the body, so that the left clamping part and the right clamping part can further relatively displace. This increases the safety of the clamp use.
Description
Technical Field
The present invention relates to a clamp, and in particular to a clamp which can be used in a building support system such as a beam or column.
Background
Beams and columns are the most basic structures in general building support systems. By the staggered design of the beams and the columns, strong support can be provided for the building, so that structures such as floors, ceilings, wall surfaces and the like can be connected and extended between the structures, and a movable space suitable for people is provided. In the building compartment, people place many things. Many of these items require hanging for use, such as photo frames, ceiling fans, and some exercise equipment. If an article is to be hung in a building compartment, it is necessary to fix one end of the hung article directly or indirectly to a beam, column, ceiling or wall. In this way, these structures are destroyed, resulting in a decrease in the overall supporting strength of the building. However, people tend to ignore the hazards of this phenomenon.
In addition to the aforementioned problems, when the hanging object is detached, the beams and the columns leave broken marks, unlike wall surfaces which can be painted or otherwise hidden. In addition, some hangers are only temporarily used and do not need to be hung for a long time. If the beam or column is subjected to destructive processing for short periods of time, it is time consuming and labor consuming.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Refer to fig. 1, which is a schematic side view of a fixture for a building support system (hereinafter referred to as the fixture) according to an embodiment of the present invention. The clamp can clamp a beam or a column in a building support system, so that other articles needing to be hung on the beam or the column can be indirectly and detachably fixed on the beam or the column through the clamp. In this embodiment, the fixture includes a left clamping portion 10, a right clamping portion 20 and a body 30. The form, combination and operation of these technical elements will be described below with reference to the accompanying drawings.
The left clamping portion 10 and the right clamping portion 20 are partially wrapped in the body 30 during operation, so that the whole view cannot be clearly seen from any direction of the clamp. For the sake of clarity of the left and right clamping portions 10 and 20, a schematic view of the clamp of fig. 1 with one side wall removed is shown in fig. 2, and cross-sections along lines AA ', BB ' in fig. 1 and CC ' in fig. 2 are shown on the left, middle and right sides of fig. 3, respectively, and a schematic view from the arrow direction of fig. 1 is shown in fig. 4. The left clamping part 10 is a slot body with a U-shaped cross section (as shown in fig. 3 and 4), linear extension and two open ends (as shown in fig. 4), at least one clamping pad 11 is fixedly connected to the outer side of the bottom, and left slots 12 are symmetrically formed on the two side walls respectively. The left clamp portion 10 according to the present invention is required to be lightweight but strong in stiffness, and stainless steel, aluminum alloy, carbon fiber, etc. may be used as a material. In this embodiment, there are 3 clamping pads 11 on the left clamping portion 10, and double faced adhesive tape or strong adhesive may be used to adhere the clamping pads 11 to the bottom of the left clamping portion 10. Preferably, the pad 11 may be designed with a protrusion 111 embedded in the bottom of the left clamping portion 10, and is matched with double faced adhesive tape or strong adhesive to enhance its shearing resistance. In practice, the clamping pad 11 may be made of rubber, and preferably has a surface with grains.
In the present embodiment, the right grip portion 20 and the left grip portion 10 are of symmetrical structure. As with the structure of the left clamping part 10 in the above-mentioned drawings, the right clamping part 20 is also a slot body with a n-shaped cross section, extending straight and having two open ends, and at least one clamping pad 21 (3 in this embodiment) is fixedly connected to the outer side of the bottom. The two side walls of the right clamping part 20 are symmetrically provided with a right slot 22 respectively. The right grip portion 20 is made of the same material as the left grip portion 10, and the grip pad 21 is bonded in the same manner.
The main body 30 is divided into a left fixing portion 31, a right fixing portion 32 and a central portion 33. The cross section of the left fixing portion 31, the right fixing portion 32 or the central portion 33 is of a U-shaped and straight-line extending design, and the cross section of the central portion 33 and the cross section of the left fixing portion 31 are respectively shown on the left side and the middle of fig. 3. In the present embodiment, the left fixing portion 31 and the right fixing portion 32 are symmetrically designed, so that only one of them is shown in the same cross-sectional design. The two ends of the central portion 33 are respectively connected to the left fixing portion 31 and the right fixing portion 32, and the extending direction of the central portion 33 is substantially perpendicular to the extending directions of the left fixing portion 31 and the right fixing portion 32, which results in the extending directions of the left fixing portion 31 and the right fixing portion 32 being parallel. The broken lines in fig. 1 are used to distinguish and illustrate the left fixing portion 31, the central portion 33 and the right fixing portion 32, and in practice, the three portions are combined to form the main body 30 (which may be integrally formed, sectionally connected or bent and cut), and no noticeable separation is necessarily required between the two adjacent portions. Stainless steel, aluminum alloy or carbon fiber may also be used for the material of the body 30 because of the required light weight and rigidity. At least one hanging device 331 (3 in this embodiment) is disposed on the outer side of the central portion 33, for connecting to the articles to be hung, such as sandbags of sports equipment. In this embodiment, the hanging device 331 is a hanging ring, and the article to be hung must be provided with a hanging buckle or other peer devices capable of being connected in an open manner to be docked with the hanging ring. Of course, the hanging device 331 may be a hanging buckle, which is designed according to the requirement. The left fixing portion 31 is provided with a pair of left penetrating bars 311 vertically between side walls thereof. The connection between the left fixing portion 31 and the left clamping portion 10 can be achieved by the pair of left penetrating rods 311 penetrating through the two left slots 12 (as shown in fig. 4), so that the left clamping portion 10 is slidably fixed in the left fixing portion 31, i.e. is sandwiched by two side walls of the left fixing portion 31. Similarly, the right fixing portion 32 is also provided with a pair of right penetrating rods 321 vertically between the side walls thereof. The right fixing portion 32 and the right clamping portion 20 may be connected by the pair of right penetrating rods 321 penetrating through the two right slots 22, so that the right clamping portion 20 is slidably fixed in the right fixing portion 32.
According to the present invention, each pair of the connecting lines passing through the fixing points of the rod on any side wall forms a sliding angle with the extending direction of the corresponding left fixing portion 31 or right fixing portion 32. The left fixing portion 31 in fig. 1 is taken as an example for explanation. In fig. 1, the line connecting the two left penetrating rods 311 is drawn by a solid arrow line, the extending direction of the left fixing portion 31 is drawn by a virtual arrow line, and the two arrow lines are disposed at a sliding angle α. The same applies to the relationship between the right fixing portion 32 and the right penetrating lever 321. According to the invention, the sliding angle may range between 10 and 25 degrees. In order to form the sliding angle, one of the two left penetrating rods 311 is farther from the center portion 33, and is positioned closer to the center line (dotted line in fig. 1) of the left and right fixing portions 31 and 32 than the other left penetrating rod 311; the two right penetrating rods 321 are farther from the central portion 33, and are located closer to the center line of the left fixing portion 31 and the right fixing portion 32 than the other right penetrating rod 321. Such a design may achieve the following effects: when the left clamping part 10 moves relative to the pair of left penetrating rods 311 through the two left slots 12, the left clamping part 10 can move towards the direction approaching or separating from the right clamping part 20; when the right clamping portion 20 moves relative to the pair of right penetrating rods 321 through the two right slots 22, the right clamping portion 20 can move toward or away from the left clamping portion 10. For a better understanding of the movement of the left clamping portion 10 and the right clamping portion 20, please refer to fig. 2, which illustrates the movement of the left clamping portion 10. Since the two left slots 12 clamp one ends of the two left penetrating bars 311, respectively, the moving direction of the left clamping portion 10 can only move along the connecting line direction (indicated by the double arrow line segment in fig. 2) of the left penetrating bars 311. The position of the left clamping portion 10 in the unused state (hereinafter referred to as "unused position") is shown by the solid line in fig. 2, and one possible position (hereinafter referred to as "used position") is shown by the broken line in fig. 2 when the left clamping portion 10 moves relative to the pair of left through-rods 311 through the two left slots 12. It is apparent that the non-use position is closer to the center line of the left and right fixing portions 31 and 32 than the use position. When the left clamp part 10 moves from the non-use position to the use position, the left clamp part 10 also moves away from the right clamp part 20; when the left clamp portion 10 is moved from the use position to the non-use position, the left clamp portion 10 is also moved in a direction approaching the right clamp portion 20. Similarly, the right grip portion 20 moves the same, but in the direction relative to the left grip portion 10. Therefore, when the left clamping portion 10 and the right clamping portion 20 move toward each other at the same time, the respective clamping pads 11 and 21 clamp a beam or column therebetween. In contrast, when the left clamping portion 10 and the right clamping portion 20 are simultaneously moved in opposite directions, the clamped beam or column can be released from the clamping.
Because the left and right clamping portions 10 and 20 are respectively sandwiched by the left and right fixing portions 31 and 32, movement of the left and right clamping portions 10 and 20 relative to the left and right fixing portions 31 and 32 is not easily controlled. For effective control, the left grip portion 10 and the right grip portion 20 have the following designs, respectively.
See fig. 4. The bottom of the left clamping portion 10 is connected to one of the pair of left through-holes 311 via a spring 312. Please refer to fig. 5, which illustrates the shape of the internal spring 312 when the left clamping portion 10 is at different positions. The left side is the case when in the non-use position, and the right side is the case when in the use position. When the left clamp 10 moves away from the right clamp 20, that is, from the unused position to the used position, the spring 312 stretches, and the length increases; conversely, the spring 312 contracts and shortens in length until it returns to the unused position, the spring 312 returning to its natural length. In this way, the left clamp 10 can be naturally set to the non-use position without the external force. Other designs may be incorporated to move from the unused position. The central portion 33 is further provided with a left through hole 332, the left through hole 332 is movably inserted through a left pull cord 333, a first end 333a of the left pull cord 333 is fixed to the left clamping portion 10, and a second end 333b of the left pull cord 333 is pulled to move the left clamping portion 10 in a direction away from the right clamping portion 20. For ease of handling, the second end 333b may be connected to a pull tab 334 for finger manipulation.
In contrast, the right clamp portion 20 also has a structure corresponding to the left clamp portion 10. The bottom of the slot body of the right clamping part 20 is connected with one of the pair of right penetrating rods 321 through a spring (not shown), and when the right clamping part 20 moves away from the left clamping part 10, the spring stretches, and the length is longer; conversely, the spring contracts and shortens until returning to the rest position, and the spring returns to its natural length. Similarly, the central portion 33 is further provided with a right through hole 335, the right through hole 335 is movably penetrated by a right pull cord 336, a third end 336a of the right pull cord 336 is fixed on the right clamping portion 20, and pulling a fourth end 336b of the right pull cord 336 can move the right clamping portion 20 in a direction away from the left clamping portion 10. Also for ease of operation, the fourth end 336b may be connected to a pull ring 337 for finger operation.
For an explanation of the usage of the present clamp, please refer to fig. 6 and 7. Fig. 6 is a schematic view of the present clamp for preparing to clamp a roof beam 1, and fig. 7 is a schematic view of the present clamp for clamping a roof beam 1. In preparation for use, the left and right holding portions 10 and 20 are moved from the non-use position to the use position (as drawn by the line in the figure) by pulling the left and right pull cords 333 and 336. At this time, the body 30 is wound around the roof beam 1 as shown in fig. 6. Then, the left and right pull cords 333 and 336 are released, and the left and right clamp portions 10 and 20 are moved toward the non-use position, that is, toward each other by the spring action of the connection, respectively. In this way, the left clamp 10 and the right clamp 20 do not return to the non-use position, but at a position before the non-use position, they are stopped moving by clamping the roof beam 1. Because the lower part of the body 30 is pulled by the weight of the hanging object, the left clamping part 10 and the right clamping part 20 are pushed towards each other further through the relative movement of the slotting and the penetrating rod, that is, the roof beam 1 is clamped more tightly. This is an advantage of the present invention in that the more heavily loaded the clip is, the safer it is to use before the maximum shear force provided by the clip pad is reached. In order to remove the clamp from the roof beam 1, the left and right pull cords 333 and 336 are pulled again, and the clamp portions 10 and 20 are pulled away from the roof beam 1. The clamp is very simple and convenient to use. If the roof beam 1 is changed into a column, the clamp clamps the column, and then the central portion 33 of the body slightly clamps the column downward due to the weight of the hanging object, so as to form a safe use state of the column when the left clamping portion 10, the right clamping portion 20 and the central portion 33 are clamped.
In the present embodiment, the cross sections of the left clamping portion 10, the right clamping portion 20, the left fixing portion 31, the right fixing portion 32 and the central portion 33 are in the shape of a U, but in other application designs, the cross sections may be in the shape of a U, or other special design shapes for facilitating the interaction between the left clamping portion 10 and the left fixing portion 31 and between the right clamping portion 20 and the right fixing portion 32.
One problem can be found from fig. 7: a gap is formed between the main body 30 and the lower portion of the roof beam 1. Of course, if the roof beam 1 is of good construction quality, a flat surface can be maintained without protrusions or depressions, and the body 30 can be closely attached thereto by the central portion 33. However, in general, the surface of the roof beam 1 is not flat, which causes the body 30 to shake in the extending direction of the roof beam 1 under dynamic load. In order to solve this problem, the present invention proposes another solution, which is described by the following examples.
Please refer to fig. 8 to 10. Fig. 8 is a schematic view showing the bottom appearance of the clamp according to another embodiment of the invention, fig. 9 is a schematic view showing the clamp of fig. 8 used for preparing the roof beam 1, and fig. 10 is a schematic view showing the first auxiliary fixing portion 40 with one side wall removed. In this embodiment, the present fixture further mounts the first auxiliary fixing portion 40 and a second auxiliary fixing portion 50. The first auxiliary fixing portion 40 is a slot body with a U-shaped cross section (or may be U-shaped) and extending linearly. However, unlike the design of the left clamping portion 10 and the right clamping portion 20, the two ends of the first auxiliary fixing portion 40 are formed in a closed shape for connection and use. One end of the first auxiliary fixing portion 40 is vertically fixed to one side middle of the central portion 33, and a first adjuster 41 is disposed in the groove body at the other end, and the length of the first adjuster 41 can be adjusted. The first auxiliary fixing portion 40 and the central portion 33 may be fixed by means of fixing means, such as at least one set of fixing bolts 60, penetrating through the central portion 33 and simultaneously latching the first auxiliary fixing portion 40 and the second auxiliary fixing portion 50. In addition, the hanging device 42 may be mounted on the first auxiliary fixing portion 40 to assist the main body 30 in increasing the mounting point of the hanging object, and the hanging device 42 may be fixed on the outside of the slot body of the first auxiliary fixing portion 40 through the fixing bolt set 43. Similarly, the second auxiliary fixing portion 50 is a slot body with a reversed U-shaped (or U-shaped) cross section and extending linearly, one end of the second auxiliary fixing portion 40 is vertically fixed in the middle of the other side of the central portion 33, a second regulator 51 is arranged in the slot body at the other end, and the second regulator 51 can also regulate the length of the second auxiliary fixing portion. The second auxiliary fixing portion 50 also has a hanging device (not shown) mounted thereon to assist the main body 30 in increasing the mounting point of the hanging object, and the hanging device can be fixed on the outside of the slot body of the second auxiliary fixing portion 50 through the fixing bolt set 53. When the beam or column is clamped by the left clamping portion 10 and the right clamping portion 20, the first adjuster 41 can adjust the length of the beam or column protruding from the first auxiliary fixing portion 40 (as shown in fig. 9), and the second adjuster 51 can adjust the length of the beam or column protruding from the second auxiliary fixing portion 50, so as to tightly contact the surface of the beam or column, so that the body 30 cannot shake in the extending direction of the beam or column.
To achieve the functions of the first regulator 41 and the second regulator 51, the first regulator 41 and the second regulator 51 may further include: an adjustment screw 451, a flat wire spring 452, and a fixing nut 453. As shown in fig. 10, the adjustment screw 451 passes through the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50. The flat wire spring 452 is mounted in the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50, and passes through the adjusting screw 451 at the center thereof. The fixing nut 453 is rotatably fixed to the adjustment screw 451 by the end of the adjustment screw 451 and compresses the flat wire spring 452. When the head of the adjustment screw 451 is rotated by force, the fixing nut 453 is not slid by the friction force existing between itself and the flat wire spring 452, and the length protruding from the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50 can be adjusted according to the relative position with the adjustment screw 451 (turning up or turning down the adjustment screw 451). Preferably, each of the first and second adjusters 41 and 51 may include a spacer 454 to reduce friction between the head of the adjusting screw 451 and the first or second auxiliary fixing portions 40 and 50.
Although the invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto but is capable of modification and variation without departing from the spirit and scope of the invention as defined in the following claims.
