Abstract
The utility model discloses a 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 on one end, provided with a side with the notch, on the supporting piece in a hinge joint mode, the other end of the supporting 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, and anti-skid threads are arranged inside the groove in the radial direction. The 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, by means of the adoption of the design of the round cake shape protrusions on the arc-shaped inner wall of the fastening piece and the anti-skid threads arranged inside the groove in the radial direction, the bracket type anti-skid cross-shaped fastener effectively prevents the steel pipe from skidding out of the cross-shaped fastener in the using process due to the fact that the steel pipe is easily affected by external force, and safety of construction is ensured.
Description
Technical field
The utility model relates to a kind of fastener, is specially the anti-slip cruciform fastening for falsework of a kind of 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, and the installing/dismounting complex operation is wasted time and energy, the problem that efficiency of construction is low, and screw-down torque 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, affects construction safety.
The utility model content
The purpose of this utility model provides the anti-slip cruciform fastening for falsework of a kind of 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 screw-down torque 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, affects the problem of construction safety.
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 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, and radially is provided with antiskid thread in the described groove.
The beneficial effects of the utility model are:
The utility model is simple in structure, when installing and using, only need fastener is fastened on the vertical steel pipe, the steel pipe of level can be by putting on fastener from great trust, easy installation and removal, effectively saved the engineering time of installing/dismounting, promoted efficiency of construction, and adopt the arc inner wall at cramp that the design that antiskid thread radially is set in patty projection and the groove is set, prevented that effectively steel pipe is affected and slippage from cruciform fastening for falsework by external force in use easily, ensured the safety of construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the anti-slip cruciform fastening for falsework of a kind of 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 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, and radially is provided with antiskid thread 7 in the groove 3.
