Description

TECHNICAL FIELD

[0001] The utility model relates to support fixing technical field, especially a support fastening device. BACKGROUND

[0002] The hanging basket is a kind of high-altitude operation equipment applied to building engineering, relative to the traditional scaffold structure, the hanging basket is erected on the outer wall of building or structure through cantilever mechanism, and the up and down movement of the hanging basket is realized by using lifting mechanism, and then the construction efficiency of high-rise building outer wall is greatly improved, and the hanging basket has gradually become the main selection direction of high-altitude construction operation.

[0003] The hanging basket support needs to be anchored and locked to ensure stable erection and the safety of outer wall construction personnel. The hanging basket base is not the center of gravity, and the load point of the hanging basket, that is, the high-altitude personnel construction is the center of gravity point, resulting in that the bottom of the hanging basket is light at high altitude, and the movement and force during work operation will cause the hanging basket at high altitude to generate transverse swinging force. These forces will eventually be applied to the hanging basket base, and different force moments will be generated, and the higher the operation, the greater the transverse swinging force generated on the base.

[0004] The hanging basket support is generally a square tube base, but the square tube and the anchoring surface need to be locked by bolts. If only the square tube is locked by bolts, the contact surface is only the square tube and the bolt, and the square tube and the anchoring surface only have a long rod contact surface, which will cause the square tube to have poor ability to withstand the swinging force at the top. With the swinging vibration of the square tube, the bolt is easily loosened, which will cause danger.

[0005] Therefore, people designed a few character cards to tighten and limit the square tube, and the few character cards are also called square clamps. This clamp extending to the left and right sides of the square tube can more stably tighten the hanging basket support on the anchoring surface. However, problems also come with it. The size of the square tube of the hanging basket support is not fixed, which will cause the height of the few character clamp limiting the square tube to be generally larger than the size of the square tube, so as to be more universal. This will cause a height difference between the square tube and the few character clamp, which will cause a movement gap between the square tube and the few character clamp. The square tube will shake under stress, and only when it touches the few character clamp, the square tube will be limited, which will cause the square tube of the hanging basket base to constantly shake under stress, which will not only affect the stability of the hanging basket, but also generate greater inertia and impact force during long-time shaking, which is also easy to cause the problem of bolt loosening.

[0006] Based on this, the utility model designs a support fastening device to solve the above problems. CONTENT OF THE UTILITY MODEL

[0031] Referring to Figures 1 to 6 The utility model provides a kind of bracket fastening device, to better understand the above technical solution, the above technical solution will be explained in detail below by combining with the drawings of the specification and specific embodiment.

[0032] In one embodiment of the technical scheme of the utility model:

[0033] It comprises N-shaped card 1, limiting piece 2, bracket square tube 3 and wedge block 4;

[0034] One adjusting hole 11 is formed in the left and right vertical side walls of N-shaped card 1, the horizontal axes of the adjusting holes 11 on both sides coincide, the adjusting holes 11 on both sides are the same in size, shape and height position, and the adjusting holes 11 on both sides are symmetrically arranged on the left and right sides of N-shaped card 1, and the adjusting hole 11 is a waist-shaped hole; N-shaped card 1 sets a waist-shaped hole as adjusting hole 11, which is to cooperate with different sizes of bracket square tube 3, the transverse through hole on bracket square tube 3 needs to be set as close to the horizontal center line position as possible, and after the hole is opened, the waist-shaped hole can be adjusted to cooperate with different sizes of bracket square tube 3 for stable locking.

[0035] The top of N-shaped card 1 is sleeved and clamped on the top of bracket square tube 3, a positioning bolt 31 is transversely inserted in the adjusting hole 11, the positioning bolt 31 passes through N-shaped card 1 and bracket square tube 3, and N-shaped card 1 and bracket square tube 3 are locked as a whole by the positioning bolt 31; A through hole is formed transversely on bracket square tube 3, and the positioning bolt 31 is inserted into the through hole of bracket square tube 3. The both ends of positioning screw 31 pass through N-shaped card 1 and bracket square tube 3, and N-shaped card 1 and bracket square tube 3 are locked as a whole by the nut.

[0036] The horizontal expansion sheet on the left and right sides of the bottom of N-shaped card 1 extends below bracket square tube 3, one anchoring hole 12 is formed in the horizontal expansion sheet on the left and right sides of the bottom of N-shaped card 1, and the horizontal expansion sheet of N-shaped card 1 refers to a sheet structure horizontally outward extending and adhering to the ground, that is, Figure 3 The sheet structure extending on the left and right sides of bracket square tube 3.

[0037] An anchor bolt 32 is vertically installed in each anchoring hole 12, and N-shaped card 1 is locked with the anchoring surface through anchor bolt 32 and anchoring hole 12; The anchoring surface is the ground or the wall surface, which is used to lock the plane of the bracket. The anchor bolt 32 is an expansion screw, and the anchoring hole 12 is a waist-shaped hole.

[0038] The limiting sheet 2 is L-shaped sheet structure, the two sides of the limiting sheet 2 are locking side and clamping side respectively, the locking hole 21 is a circular hole, and the locking side and the clamping side of the limiting sheet 2 are perpendicular to each other. Figure 1 As shown in the figure, the locking hole on the locking side of the limiting sheet 2 is locked with the bracket square tube 3 through the positioning bolt 31 and the adjusting hole 11, which ensures the stability of the structure.

[0039] The clamping side of the limiting sheet 2 can effectively limit the left and right directions of the wedge block 4. If the engineering quantity is large, the size matching wedge block 4 and limiting sheet 2 can be customized to ensure that the width gap between the wedge block 4 and the clamping side of the limiting sheet 2 is within 2mm.

[0040] A locking hole 21 is arranged on the locking side of the limiting sheet 2, the limiting sheet 2 is locked on the vertical outer side wall of the U-shaped card 1 through the positioning bolt 31, the clamping side of the limiting sheet 2 vertically extends downward below the bracket square tube 3, and the clamping side of the limiting sheet 2 extends outside the U-shaped card 1;

[0041] The wedge block 4 is tightly wedged below the bracket square tube 3, and the bracket square tube 3 is arranged between the clamping side of the limiting sheet 2 and the U-shaped card 1. The wedge block 4 is a non-carbon steel wedge block, the bottom of the wedge block 4 is provided with a wave-shaped anti-skid pattern, and the inclined surface of the wedge block 4 is also provided with a wave-shaped anti-skid pattern.

[0042] It should be noted that:

[0043] 1. When the U-shaped card 1 is locked with the square tube hoop now, the U-shaped card 1 will be stably locked with the anchoring surface, and the internal height of the square tube and the U-shaped card 1 is not consistent. Once the thickness of the square tube is less than the height of the U-shaped card 1, a gap will be generated, which can only be tightly pressed with the wedge block 4. This way will cause the U-shaped card 1, the bracket square tube 3 and the wedge block 4 to be in a separated state, too many active connection relationships, and slight vibration will cause one of them to move. Once one component moves, it will cause the whole to be scattered and loose, which is not conducive to stably locking the hanging basket support. The device directly locks the bracket square tube 3 and the U-shaped card 1 as a whole structure through the positioning bolt 31, completely avoiding the possibility of loosening of the U-shaped card 1 and the bracket square tube 3, and limiting the activity space between each component through the limiting sheet 2, further increasing the structural stability.

[0044] 2. The bottom and the supporting inclined surface of the wedge block 4 are generally stable, but when subjected to vibration and shaking, the supporting force is prone to deflection, causing the wedge block 4 to shake as well, causing the wedge block 4 to move horizontally to the left and right, losing sufficient supporting effect. This device can limit the wedge block 4 through the locking side of the limiting piece 2 to ensure that the wedge block 4 does not move horizontally, and the bottom and inclined surface of the wedge block 4 are provided with anti-slip grooves, which can prevent it from loosening directly outward, effectively ensuring the supporting effect of the wedge block 4. When the wedge block 4 is inserted, it should rest against the locking side of the limiting piece 2 so that three surfaces of the wedge block 4 are all pressed against and clamped. If a wedge block 4 with a width basically the same as the width between the edge of the card 1 and the locking side of the limiting piece 2 can be selected, it will be more stable.

[0045] When the utility model is used, the installation position is determined, and then the card 1 is hung on the top of the bracket square tube 3, and the bracket square tube 3 is positioned by adjusting the position of the hole 11, and the bracket square tube 3 is drilled as much as possible according to the position of the top edge of the adjusting hole 11.

[0046] A through hole needs to be drilled horizontally on the bracket square tube 3. After the drilling is completed, a positioning bolt 31 is inserted into the through hole of the bracket square tube 3. At the same time, the positioning bolt 31 also passes through the locking hole 21, and the limiting plate 2 is also put on the positioning bolt 31. The positioning bolt 31 also needs to pass through the adjustment hole 11 of the "J" card 1, so that the "J" card 1, the limiting plate 2 and the bracket square tube 3 are locked together by the positioning bolt 31 to form an overall force-bearing structure.

[0047] Then take anchor bolt 32, be inserted in anchor hole 12 places, and anchor bolt 32 is locked on the ground, guarantee several character cards 1 and ground anchoring locking. Now, several character cards 1 just all locked with ground and support square tube 3.

[0048] Finally, insert the wedge block 4 under the bracket square tube 3. The wedge block 4 needs to be stuck in the gap between the clamping side of the limiting piece 2 and the side wall of the "X" clamp 1. The wedge block 4 is also positioned to ensure that it is clamped tightly.
