Abstract

The utility model discloses a reinforced bracket type anti-skid cross-shaped fastener which comprises a supporting piece and a fastening piece, an arc-shaped groove is arranged in the middle of the supporting piece, an arc-shaped notch is concaved inwards on one side of the supporting piece one end of the fastening piece is arranged at an end, provided with a side of the notch, on the supporting piece in a hinge joint mode, the other end of the fastening piece is provided with a fork-shaped opening and tightly fixed on the other end, provided with the notch side, on the supporting piece through a slipknot bolt, the fastening piece is in an arc shape and matched with the notch of the supporting piece to form an oval fastening portion used for clamping a steel pipe, round cake shape protrusions are arranged on an arc-shaped inner wall of the fastening piece in a stamping mode, arc-shaped reinforced ribs are arranged on an arc-shaped outer wall of the fastening piece, anti-skid threads are arranged inside the groove in the radial direction, and reinforced ribs are arranged on the reverse side of the supporting piece along the groove in the radial direction. The reinforced bracket type anti-skid cross-shaped fastener is simple in structure, convenient to assemble and disassemble, effectively saves construction time of assembly and disassembly, improves construction efficiency, has good mechanical strength and anti-skid performance, and effectively ensures safety of construction.

Description

The anti-slip cruciform fastening for falsework of a kind of reinforced bracket type
Technical field
The purpose of this utility model provides a kind of fastener, is specially the anti-slip cruciform fastening for falsework of a kind of reinforced bracket type.
Background technology
The appearance of steel tube scaffold clasp so that steel pipe scaffold mounting or dismounting are convenient, is set up more flexibly, because steel pipe length is easy to adjust, fastener connects easy, thereby can adapt to building and the structure scaffold of various planes, facade.At present, the steel tube scaffold clasp that building operations is used, generally adopt the circular arc fastener of two make-ups of right-angled intersection to be bolted formation, fastener is installed in the steel pipe infalls that need two fastening vertical intersections, and tight a bolt with the steel pipe of fastening vertical intersection by spanner, finish the work of setting up of scaffold.Yet existing cruciform fastening for falsework exists complex structure various, the installing/dismounting complex operation, waste time and energy, the problem that efficiency of construction is low, and because cruciform fastening for falsework in use frequently is subject to the effect of multiple external force, cause easily cruciform fastening for falsework distortion, cracking and damage, and then affect result of use and the construction safety of cruciform fastening for falsework; The screw-down torque of cruciform fastening for falsework does not reach the regulation requirement, frequently is subject to curved, as the active force such as to turn round impact in the use procedure and causes easily the steel pipe slippage, can affect the safety of construction yet.
The utility model content
The purpose of this utility model provides the anti-slip cruciform fastening for falsework of a kind of reinforced bracket type, various to solve cruciform fastening for falsework complex structure traditional in the prior art, the installing/dismounting complex operation, waste time and energy, efficiency of construction is low, and cruciform fastening for falsework mechanical strength and screw-down torque do not reach the regulation requirement, in use frequently is subject under the effect of multiple external force, cause easily cruciform fastening for falsework distortion, cracking and damage and occur the phenomenon of steel pipe slippage, and then affect the problem of working security.
For achieving the above object, the technical solution adopted in the utility model is:
The anti-slip cruciform fastening for falsework of a kind of reinforced bracket type, it is characterized in that: include supporting spring and cramp, described supporting spring middle part is provided with circular groove, described supporting spring one side direction sunken inside has the circular arc gap, one end of described cramp is hinged on the end that supporting spring is provided with the gap side, the other end of described cramp is provided with the fork-shaped opening and is provided with the other end of gap side by the slip-knot bolton at supporting spring, described cramp is curved and match with the supporting spring gap and to be formed for clamping the oval buckle portion of steel pipe, the arc inner wall of described cramp is provided with the patty projection that is stamped to form, the arc outer wall of described cramp is provided with the reinforcing rib of arc, radially be provided with antiskid thread in the described groove, the described supporting spring back side radially is provided with reinforcing rib along groove.
The reinforcing rib array that described reinforcing rib consists of for several reinforcing ribs that are parallel to each other.
Described supporting spring, cramp and slip-knot bolt all adopt grey cast-iron to make.
Described supporting spring, cramp and slip-knot bolt surface are equipped with zinc-plated antirust coat.
The beneficial effects of the utility model are:
The utility model is simple in structure, has effectively promoted the mechanical strength of cruciform fastening for falsework, even so that cruciform fastening for falsework in use is subjected to frequently external force to affect also not yielding, cracking and damages, ensured the safety of construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure schematic diagram of cramp in the utility model.
Fig. 3 is the structure schematic diagram of supporting spring in the utility model.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the anti-slip cruciform fastening for falsework of a kind of reinforced bracket type, include supporting spring 1 and cramp 2, supporting spring 1 middle part is provided with circular groove 3, supporting spring 1 one side direction sunken insides have circular arc gap 4, one end of cramp 2 is hinged on the end that supporting spring 1 is provided with the gap side, the other end of cramp 2 is provided with the fork-shaped opening and is fastened on the other end that supporting spring 1 is provided with the gap side by slip-knot bolt 5, cramp 2 is curved and match with supporting spring 1 gap 4 and to be formed for clamping the oval buckle portion of steel pipe, the arc inner wall of cramp 2 is provided with the patty projection 6 that is stamped to form, the arc outer wall of cramp 2 is provided with the reinforcing rib 8 of arc, radially be provided with antiskid thread 7 in the groove 3, supporting spring 1 back side radially is provided with reinforcing rib 9 along groove 3.
Reinforcing rib 8, the 9 reinforcing rib arrays for several reinforcing ribs formations that are parallel to each other.Supporting spring 1, cramp 2 and slip-knot bolt 5 all adopt grey cast-iron to make.Supporting spring 1, cramp 2 and slip-knot bolt 5 surfaces are equipped with zinc-plated antirust coat.
