The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1 to Figure 12, the horizontal safety net hanging structure that embodiment of the present utility model provides comprises girder steel, for covering the safety net that covers hole 200 that girder steel surrounds, be arranged on some snap rings 300 on safety net 200 relative both sides, wear the some fixtures on the wire rope 400 that coordinates and clamp cover hole outside bottom flange being positioned at of girder steel with snap ring 300.Fixture is arranged on and covers outside hole, even if there is falling object to fall, is also unlikely to impact fixture and makes its slippage from girder steel, has increased protection intensity.
Girder steel comprises along what lay that direction extends and covers the parallel girder steel 110 outside hole, conversion girder steel 130 and with the parallel girder steel 110 vertical extension girder steel 150 vertical with parallel girder steel 110.Each girder steel all covers hole setting around correspondence.Wherein, conversion girder steel 130 is in adjacent covering between hole, and extension girder steel 1156 is positioned at outermost one end of covering hole.
Fixture comprise clamp on parallel girder steel 110 bottom flanges, outside for the beam lower clamp 510 of tense wire rope, clamp on conversion girder steel 130 bottom flanges, rear for changing switch fixture 530 and clamp beam lower draw-bar 550 for coordinating with wire rope 400 ends on extension girder steel 150 bottom flanges, outside of safety net cloth set direction.Wire rope 400 is fixed on the outer side-lower of parallel girder steel 110 by beam lower clamp 510, switch fixture 530 and beam lower draw-bar 550.Switch fixture 530 covers the trend of the wire rope 400 that hole is corresponding and guarantees that wire rope 400 hangs under beam securely for adjusting rear; thereby realize the shape conversion that under beam, safety net 200 is laid; be convenient to lay a large safety net in the adjacent hole location of covering, form common safeguard protection.
Referring to Fig. 2 to Fig. 7, beam lower clamp 510 comprises with preset distance compartment of terrain and is folded in the fastener 511 of corresponding girder steel bottom flange, fastener 511 is locked to the lock bolt 513 of corresponding girder steel bottom flange and is fixed on fastener 511 perforated plates 515 of Yi Ce bottom, back for coordinating with wire rope 400.Particularly, fastener 511 takes the shape of the letter U, it is connected on the bottom flange, outside of parallel girder steel 110, the top of fastener 511 is arranged side by side spaced two perforates 5112 along the length direction of girder steel, and fastener 511 bottoms and perforated plate 515 are coplanar and be fixed together by mode and the perforated plate 515 of full penetration.Lock bolt 513 is two, and is all full silk screw rod, to coordinate with perforate 5112, quickly fastener 511 is fastened on girder steel or from girder steel and is disassembled with convenience and high-efficiency.Perforation 5152 is set on perforated plate 515.Please refer to Fig. 6 and Fig. 7, wire rope 400 except its end be coordinate by 51 tensions of split bolt 600 and beam lower clamp, mid portion is all directly to wear and coordinate with perforated plate 515, thus it is fixing that wire rope 400 is tightened.Please refer to Fig. 5, beam lower clamp 510, except being subject to wire rope 400 reversal interlocking relays, is also subject to the pulling force of safety net towards parallel girder steel 110 directions.If safety net is subject to external impacts, 510 of beam lower clamps can be subject to the larger pulling force towards parallel girder steel 110 directions and be unlikely to slippage from parallel girder steel 110, therefore, beam lower clamp 510 more can adapt to high-intensity job site, be conducive to reduce the demand of fixture, facilitate site operation, improve efficiency of construction, thereby reduce manpower and materials cost.In the present embodiment, one end of wire rope 400 coordinates with beam lower clamp 510 by split bolt 600, and the other end coordinates with beam lower draw-bar 550, thereby is tauted; In other embodiments, the two ends of wire rope 400 all can coordinate with beam lower clamp 510 by split bolt 600.
Referring to Fig. 8 to Figure 10, switch fixture 530 comprises and is folded in the fastener 531 of corresponding girder steel bottom flange, fastener 531 is locked to the lock bolt 533 of corresponding girder steel bottom flange and is fixed on the selector bar 535 outside fastener 531.Particularly, fastener 531 takes the shape of the letter U, and it is connected on the bottom flange, outside of conversion girder steel 130, and the top of fastener 531 is arranged side by side spaced two perforates along the length direction of girder steel.Selector bar 535 takes the shape of the letter U and arranges in the same way with fastener 531, its two ends respectively with lower surface and the top surface secure fit of fastener 531, and the back of middle part and fastener 531 is at a distance of preset distance.Lock bolt 533 is two, and is all full silk screw rod, to coordinate with perforate, quickly fastener 531 is fastened on girder steel or from girder steel and is disassembled with convenience and high-efficiency.Please refer to Figure 10, switch fixture 530 clamps are on conversion girder steel 130 and the corresponding bottom flange, outside of covering the parallel girder steel 110 of hole of next-door neighbour, and its selector bar 535 is parallel with the corresponding parallel girder steel 110 that covers hole.Switch fixture 530 is clamped in wire rope 400 by clip 5352 selector bar 535 times of switch fixture 530.Clip 535 comprises the connecting plate that is wrapped in the resettlement section of the C shape outside wire rope 400 and selector bar 535 and extends to form from the edge in opposite directions of resettlement section; on connecting plate, wear bolt and can draw in or open under the effect of bolt, thereby making resettlement section that wire rope 400 and selector bar 535 are clamped or be unclamped.That is to say, wire rope 400 is consistent with the length direction of selector bar 535 corresponding to the trend of rear masking aperture cavity portion.
Please refer to Figure 11 and Figure 12, beam lower draw-bar 550 comprises clamp at the fastener 551 of extension girder steel 150 bottom flanges, outside and fastener 551 is locked to the lock bolt 553 of corresponding girder steel bottom flange.Particularly, fastener 551 comprises clamping limb 5512, lower clamping limb 5516 and connects the linking arm 5518 of upper clamping limb 5512 and lower clamping limb 5516.The free end of upper clamping limb 5512 arranges nut 5513, for coordinating with lock bolt 553, thereby fastener is locked to the bottom flange of corresponding girder steel.The free end of lower clamping limb 5516 arranges through hole 5517, for wearing and coordinate with the end of wire rope 400 for wire rope 400, thereby wire rope 400 is tightened.
Because horizontal safety net hanging structure of the present utility model is arranged on fixture in the outside of covering hole, fixture adapts to high-intensity site operation more, reduces fixture demand to reduce manpower and materials, facilitates site operation, improves efficiency of construction.The design of safety net entirety laying form and switch fixture, can realize multiple hole and lay a safety net.In the utility model, according to site environment and stressing conditions, this horizontal safety net hanging structure can be laid different fixtures in different positions, in the laying of convenient and safe net, can also reduce manpower and materials, improves security protection intensity.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
