Description

Clamps for Building Support Systems

The present invention relates to a jig, particularly a jig that can be used in building support systems, such as beams or columns.

Beams and columns are the most basic structures in general building support systems. Through the staggered design of beams and columns, the building can provide strong support, so that the floors, ceilings, walls and other structures can be connected and extended between them, providing people with a suitable space for activities. In the compartments of the building, people will place a lot of supplies. Many of these supplies need to be hung, such as photo frames, ceiling fans, and some fitness equipment. To hang objects in the building compartment, one end of the hanging objects must be fixed directly or indirectly on beams, columns, ceilings or walls. As a result, these structures will be damaged, resulting in a reduction in the overall supporting strength of the building. However, people often ignore the harm caused by this phenomenon.

Taking beams and columns as an example, if you directly "nail" the hanging objects into them and hang them, in addition to the aforementioned problems, when the hanging objects are removed, there will be traces of damage left on them, unlike a wall. The surface can be decorated or otherwise covered with other items. In addition, some hanging objects are only used temporarily and do not need to be hung for a long time. Destructive treatment of beams or columns for short-term needs is time-consuming and labor-intensive.

Therefore, in order to meet the above-mentioned temporary fixing requirements for hanging objects on beams or columns, the present invention has been developed and proposed.

Schematic.

The present invention will be described more specifically by referring to the following embodiments.

Please 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. This clamp can clamp a beam or beam in a building support system The first is a column, and other items that need to be hung on the beam or column can be indirectly and detachably fixed on the beam or column through this fixture. In this embodiment, the clamp 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 by referring to the related drawings.

The left clamping part 10 and the right clamping part 20 are partially enclosed in the main body 30 during operation, so the whole view cannot be clearly seen from any direction of the clamp. In order to have a clearer description of the left clamping part 10 and the right clamping part 20 , the schematic diagram of the clamp in FIG. 1 with one side wall removed is shown in FIG. 2 , along the line AA′, BB in FIG. ' line and the cross-section along the CC' line in FIG. 2 are respectively shown on the left, middle and right sides of FIG. 3 , and a schematic diagram viewed from the direction of the arrow in FIG. 1 is shown in FIG. 4 . The left clamping portion 10 is a groove body with a cross-section of a ㄇ shape (as shown in Figures 3 and 4), straight extending and open at both ends (as shown in Figure 4), and at least one clamping pad 11 is fixed to the outside of the bottom. , a left slot 12 is symmetrically opened on the two side walls respectively. According to the present invention, the requirement of the left clamping portion 10 is that it is light in weight but strong in stiffness, and can be made of, but not limited to, stainless steel, aluminum alloy, carbon fiber, and the like. In this embodiment, there are three clamping pads 11 on the left clamping portion 10 , and the clamping pads 11 can be bonded to the bottom of the left clamping portion 10 by using double-sided tape or strong adhesive. Preferably, the clip pad 11 can be designed with a protrusion 111, which is embedded into the bottom of the left clip portion 10, and is matched with double-sided tape or strong adhesive to enhance its shear resistance. In practice, the clamping pad 11 can be made of rubber, and the surface has a texture.

In this embodiment, the right clamping part 20 and the left clamping part 10 are symmetrical structures. Like the structure of the left gripping portion 10 in the preceding figures, the right gripping portion 20 is also a groove body with a cross-sectional shape of ㄇ, extending straight and open at both ends, and at least one gripping pad 21 (this 3 in the example). A right slot 22 is also symmetrically defined on both side walls of the right clamping portion 20 . In addition, the material used for the right clamping part 20 is the same as that of the left clamping part 10 , and the coupling method of the clamping pad 21 is also the same.

The body 30 can be divided into a left fixing portion 31 , a right fixing portion 32 and a central portion 33 . Whether it is the left fixing portion 31 , the right fixing portion 32 or the central portion 33 , the cross-sections are all U-shaped and designed to extend straight. The cross-sections of the central portion 33 and the left fixing portion 31 are shown in FIG. 3 , respectively. left and middle. In this embodiment, the left fixing portion 31 and the right fixing portion 32 are symmetrically designed, so the cross-sectional designs are the same, and only one of them is shown. Both ends of the central portion 33 are respectively connected to the left fixing portion 31 and the right fixing portion 32 , and the extension direction of the central portion 33 is substantially perpendicular to the extending direction of the left fixing portion 31 and the right fixing portion 32 , which leads to the result that the left fixing portion 31 and the right fixing portion 32 extend. The extending directions of 32 are parallel. The dotted line in FIG. 1 is used to distinguish the left fixing part 31 , the central part 33 and the right fixing part 32 . In practice, the three are combined to form the main body 30 (which can be integrally formed, segmented, or bent and cut. ), there is not necessarily a perceptible separation pattern between the two adjacent ones. Because the material is required to be light and rigid, the material of the body 30 can also be made of stainless steel, aluminum alloy or carbon fiber. At least one hanging device 331 (three in this embodiment) is arranged on the outer side of the central portion, which is used to connect the objects that need to be hung, such as sandbags of sports equipment. In this embodiment, the suspending device 331 is a hoisting ring, and the object to be hoisted must be provided with a suspending buckle or other open-connectable equivalent device for docking with it. Of course, the hanging device 331 can also be a hanging buckle, which is designed according to requirements. A pair of left penetrating rods 311 are vertically installed between the side walls of the left fixing portion 31 . The connection between the left fixing part 31 and the left clamping part 10 can be achieved by passing the pair of left piercing rods 311 through the two left slots 12 (as shown in FIG. 4 ), so that the left clamping part 10 can be slidably fixed on the Inside the left fixing portion 31 , that is, it is sandwiched by both side walls of the left fixing portion 31 . Similarly, a pair of right penetrating rods 321 are vertically installed between the side walls of the right fixing portion 32 . The connection between the right fixing portion 32 and the right clamping portion 20 can be achieved by passing the pair of right passing rods 321 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, the connecting direction of the fixing points on any side wall of each pair of piercing rods forms a sliding angle with the extending direction of the corresponding left fixing portion 31 or the right fixing portion 32 . Take the left fixing part 31 in FIG. 1 as an example Bright. In FIG. 1 , the connection line between the two left piercing rods 311 is depicted by a solid arrow line, and the extending direction of the left fixing portion 31 is depicted by a dotted arrow line, and the two arrow lines sandwich a sliding angle α . The relationship between the right fixing portion 32 and the right insertion rod 321 is also the same. According to the present invention, the sliding angle can range between 10 degrees and 25 degrees. In order to form the aforementioned sliding angle, one of the two left piercing rods 311 that is farther from the center portion 33 is located closer to the center line of the left fixing portion 31 and the right fixing portion 32 than the other left piercing rod 311 (the one in FIG. 1 ). Dotted line); one of the two right piercing rods 321 that is farther from the central portion 33 is located closer to the center line of the left fixing portion 31 and the right fixing portion 32 than the other right piercing rod 321 . Such a design can cause the following effects: when the left gripping portion 10 moves relative to the pair of left piercing rods 311 through the two left slots 12, the left gripping portion 10 can move toward or away from the right gripping portion 20; When the right clamping portion 20 moves relative to the pair of right piercing rods 321 through the two right slots 22 , the right clamping portion 20 can move toward or away from the left clamping portion 10 . In order to have a better understanding of how the left clamping portion 10 and the right clamping portion 20 move, please refer to FIG. 2 again, where the movement of the left clamping portion 10 is taken as an example for description. Since the two left slots 12 clamp one end of the two left piercing rods 311 respectively, the moving direction of the left clamping portion 10 can only be along the line connecting the left piercing rods 311 (see the double arrow line segment in FIG. 2 ). shown) move. The position of the left clamping portion 10 in the non-use state (hereinafter referred to as the non-use position) is shown by the solid line in FIG. 2 . When 311 moves, a possible position (hereinafter referred to as the use position) is shown by the dotted line in FIG. 2 . Obviously, the unused position is closer to the center line of the left fixing portion 31 and the right fixing portion 32 than the used position. When the left gripping portion 10 moves from the unused position to the use position, the left gripping portion 10 also moves away from the right gripping portion 20; when the left gripping portion 10 moves from the use position to the unused position , the left gripping portion 10 also moves toward the direction of approaching the right gripping portion 20 . Likewise, the right gripping portion 20 moves in the same way, but in a direction relative to the left gripping portion 10 . Therefore, when the left clamping part 10 and the right clamping part 20 move in the opposite direction at the same time, their respective clamping pads 11 and 21 can clamp a beam or a column therebetween. opposite In other words, when the left clamping part 10 and the right clamping part 20 move in opposite directions at the same time, the clamped beam or column can be released from clamping.

Because the left clamping part 10 and the right clamping part 20 are respectively sandwiched by the left fixing part 31 and the right fixing part 32 , the left clamping part 10 and the right clamping part 20 are relative to the left fixing part 31 and the right fixing part 32 Movement is not very easy to control. For effective control, the left gripping portion 10 and the right gripping portion 20 have the following designs respectively.

See Figure 4. For the left clamping part 10 , the bottom of the groove body is connected to one of the pair of left through rods 311 through a spring 312 . Please refer to FIG. 5 , which shows the shape of the inner spring 312 when the left clamping portion 10 is in different positions. The left is when in the non-use position, and the right is when in the used position. When the left clamping part 10 moves away from the right clamping part 20, that is, from the non-use position to the use position, the spring 312 stretches and the length becomes longer; otherwise, the spring 312 contracts and the length becomes shorter until it returns to In the unused position, the spring 312 returns to its natural length. In this way, under the action of no external force, the left clamping portion 10 can be set at the unused position. To move from the unused position, it can be matched with other designs. The central portion 33 further defines a left through hole 332 , and a left pull cord 333 is movably passed through the left through hole 332 . The two ends 333b can move the left clamping part 10 away from the right clamping part 20 . For convenient operation, a pull ring 334 can be connected to the second end 333b for finger operation.

Correspondingly, the right clamping portion 20 also has a structure corresponding to the left clamping portion 10 . The bottom of the groove body of the right clamping portion 20 is connected with one of the pair of right passing rods 321 through a spring (not shown). When the right clamping portion 20 moves away from the left clamping portion 10 , the spring stretches , the length becomes longer; on the contrary, when it shrinks, the length becomes shorter until it returns to the unused position, and the spring returns to its natural length. Similarly, a right through hole 335 is further opened in the central part, and a right pull rope 336 is movably passed through the right through hole 335, and a third end 336a of the right pull rope 336 is fixed on the right In the clamping part 20 , pulling a fourth end 336 b of the right pulling rope 336 can move the right clamping part 20 away from the left clamping part 10 . Also for the convenience of operation, the fourth end 336b can be connected with a pull ring 337 for finger operation.

To illustrate how this fixture is used, see Figures 6 and 7. FIG. 6 is a schematic diagram of the fixture preparing to clamp a roof beam 1 , and FIG. 7 is a schematic diagram of the fixture clamping the roof beam 1 . In preparation for use, the left gripping portion 10 and the right gripping portion 20 are moved from the non-use position to the use position (the position drawn by the required line in the figure) by pulling the left drawstring 333 and the right drawstring 336 first. At this time, the main body 30 is surrounded by the roof beam 1, as shown in FIG. 6 . Next, the left pull cord 333 and the right pull cord 336 are released, and the left gripping portion 10 and the right gripping portion 20 are respectively acted by the connected springs and move toward the unused position, that is, move toward each other. In this way, although the left gripping portion 10 and the right gripping portion 20 will not return to the unused position, at a certain position before the unused position, the two stop moving due to sandwiching the roof beam 1 . Since the lower part of the main body 30 is pulled by the weight of the hanging object, the left clamping part 10 and the right clamping part 20 are further pushed toward each other through the relative movement of the slot and the piercing rod, that is, the roof beam 1 is clamped. tighter. This is an advantage of the present invention, that is, the heavier the load, the safer the use of the clamp before the maximum shear force value provided by the clamp pad is reached. To remove the fixture from the roof beam 1 , it is only necessary to pull the left pull rope 333 and the right pull rope 336 again to pull the left clamping part 10 and the right clamping part 20 away from the roof beam 1 . This fixture is very easy to use. If the roof beam 1 is changed to a column, after the clamp clamps the column, the central part 33 of the main body will clamp the column slightly downward due to the weight of the hanging object, thereby forming the left clamping part 10 and the right clamping part 10 . The clamping part 20 and the central part 33 simultaneously clamp the cylinder in the safe use state.

In this embodiment, although 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 ℇ, in other application designs, the transverse The cross-section can also be U-shaped, or other special design shapes that facilitate the interaction between the left clamping portion 10 and the left fixing portion 31 and the right clamping portion 20 and the right fixing portion 32 .

A problem can be found from FIG. 7 : there is a gap between the main body 30 and the roof beam 1 . Of course, if the roof beam 1 is of good quality during construction, and can maintain a flat surface without protrusions or depressions, the body 30 can be closely connected with the central portion 33 . However, in general, the surface of the roof beam 1 is not flat, which causes the body 30 to sway 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 illustrated by the following embodiment.

See Figures 8 to 10. 8 is a schematic view of the bottom appearance of the clamp according to another embodiment of the present invention, FIG. 9 is a schematic view of using the clamp of FIG. 8 to prepare to clamp the roof beam 1, and FIG. 10 is a first auxiliary fixing part 40 with one side removed Schematic of the side wall. In this embodiment, the fixture is further installed with a first auxiliary fixing portion 40 and a second auxiliary fixing portion 50 . The first auxiliary fixing portion 40 is a groove body with a cross section of a U-shape (or a U-shape) and extending straight. However, different from the design of the left clamping portion 10 and the right clamping portion 20 , both ends of the first auxiliary fixing portion 40 are closed for connection and use. One end of the first auxiliary fixing portion 40 is vertically fixed to the middle of one side of the central portion 33 , and a first adjuster 41 is arranged in the groove body at the other end, and the first adjuster 41 can adjust its own length. The fixing method of the first auxiliary fixing part 40 and the central part 33 may be a fixing device, such as at least one or more fixing bolt groups 60 , passing through the central part 33 and simultaneously connecting the first auxiliary fixing part 40 and the second auxiliary fixing part 50 The latch is fixed. In addition, a hanging device 42 can also be installed on the first auxiliary fixing part 40 to assist the main body 30 to increase the hanging point of the hanging object, and the hanging device 42 can be fixed to the groove of the first auxiliary fixing part 40 through the fixing bolt group 43 outside of the body. Similarly, the second auxiliary fixing portion 50 is also a trough body with a cross-section of a U-shape (or a U-shape) and extending straight. One end of the first auxiliary fixing portion 40 is symmetrically fixed to the middle of the other side of the central portion 33. , a second adjuster 51 is arranged inside the tank body at the other end, and the second adjuster 51 can also adjust its own length. A hanging device (not shown) is also installed on the second auxiliary fixing part 50 to assist the main body 30 to increase the hanging point of the hanging object. The hanging device can be fixed to the groove of the second auxiliary fixing part 50 through the fixing bolt group 53 outside. When the beam or column is the left clamping part 10 When clamped with the right clamping portion 20, the length of the first adjuster 41 protruding from the first auxiliary fixing portion 40 can be adjusted (as shown in FIG. 9), and the second adjuster 51 can be adjusted to protrude from the first auxiliary fixing part 40. The length of the two auxiliary fixing parts 50 is closely connected with the surface of the beam or the column, so that the body 30 will not shake in the extending direction of the beam or the column.

In order to achieve the functions of the first adjuster 41 and the second adjuster 51 , the first adjuster 41 and the second adjuster 51 may further include an adjusting screw 451 , a flat wire spring 452 and a fixing nut 453 respectively. As shown in FIG. 10 , the adjusting screw 451 passes through the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50 . The flat wire spring 452 is installed in the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50 , and the center thereof passes through the adjusting screw 451 . The fixing nut 453 is rotatably fixed to the adjusting screw 451 by the end of the adjusting screw 451 , and compresses the flat wire spring 452 . When the head of the adjusting screw 451 is forced to rotate, the fixing nut 452 will not slide due to the frictional force existing between itself and the flat wire spring 452, and thus can change (turn up or turn up) with the relative position of the adjusting screw 451. Lower the adjusting screw 451) to adjust the length protruding from the first auxiliary fixing part 40 or the second auxiliary fixing part 50. Preferably, each of the first adjuster 41 and the second adjuster 51 may include a washer 454 to reduce the frictional force between the head of the adjusting screw 451 and the first auxiliary fixing portion 40 or the second auxiliary fixing portion 50 .
