Background

During bridge construction, a common construction process is that a hanging basket is used for cantilever pouring construction, a template is arranged on a hanging basket template system firstly, and then concrete pouring construction is completed. The hanging basket pouring construction is used as a mature construction process.

In recent years, as materials are improved, steel strips or finish-rolled threaded steel hanger rods are generally used as hanging basket hanger rods. When the steel strip is used as a hanging basket suspender, on one hand, the steel strip is heavy, so that the disassembly and the assembly are difficult, and on the other hand, the steel strip is connected with the distribution amount by adopting a pin joint, so that the fastening process is complicated; when using finish rolling screw-thread steel, can cause the jib to receive the turn round, because finish rolling screw-thread steel is fragile material, produces the potential safety hazard easily, and appears easily because hang basket welding construction operation accidental injury finish rolling screw-thread steel and lead to cracked problem.

The utility model adopts the following technical scheme: a hanging basket suspender for bridge construction is used as a front suspender in a hanging basket template system and comprises a suspender body, wherein the suspender body is a solid bar;

the two end parts of the suspender body are respectively provided with a first thread section and a second thread section, and the threads of the first thread section and the second thread section are both trapezoidal threads;

nuts are connected to the first thread section and the second thread section in a threaded mode, and each nut is provided with an internal thread matched with the trapezoidal thread;

the first thread section is used for penetrating through an upper distribution beam of the hanging basket and is matched with a nut to suspend the suspender body on the upper distribution beam; the second thread section is used for being matched with the nut to suspend the lower distribution beam of the hanging basket on the hanging rod body.

Furthermore, an anchor backing plate is further sleeved on the suspender body and is positioned between the nut and the upper distribution beam/the lower distribution beam.

Further, the anchor backing plate is a flat plate with an inner circle and an outer square.

Further, at least two rotating handles are arranged on the periphery of the nut.

Furthermore, a gripping hole is formed on the rotating handle.

The utility model has the advantages that: the utility model discloses a solid rod can bear the torsion that the jib receives as the jib body, cooperatees through trapezoidal thread and nut simultaneously and can avoid welding, reduces the welding risk, has also increased the convenience of operation.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a hanging basket suspender for bridge construction, which is used as a front suspender in a hanging basket template system as shown in figure 1, and comprises a suspender body 1, wherein the suspender body 1 is a solid bar; as shown in fig. 2, the two end parts of the suspender body 1 are respectively provided with a first thread section 2 and a second thread section 3, and the threads of the first thread section 2 and the second thread section 3 are both trapezoidal threads; the first thread section 2 and the second thread section 3 are both in threaded connection with nuts 4, and the nuts 4 are provided with internal threads matched with the trapezoidal threads; the first thread section 2 is used for penetrating through an upper distribution beam of the hanging basket and is matched with a nut 4 to suspend the suspender body 1 on the upper distribution beam; the second thread section 3 is used for being matched with the nut 4 to suspend the lower distribution beam of the hanging basket on the hanging rod body 1.

The utility model discloses a solid rod can bear the torsion that the jib receives as the jib body, cooperatees through trapezoidal thread and nut simultaneously and can avoid welding, reduces the welding risk, has also increased the convenience of operation.

In this embodiment, the hanger bar body 1 is a solid bar that meets current regulatory and government requirements. Preferably, jib body 1 replaces traditional finish rolling screw-thread steel, makes things convenient for near 1 electric welding construction of jib body.

In the present embodiment, the nut 4 has an internal thread that cooperates with the trapezoidal thread. The trapezoidal thread is one of threads and is divided into a metric system and an English system. The tooth form angle of the English trapezoidal thread is 29 degrees, the common Chinese trapezoidal thread is a metric trapezoidal thread, the tooth form angle is 30 degrees, the tooth form is an isosceles trapezoid, the English trapezoidal thread is usually used for transmission of some mechanisms, and certain strength and rigidity requirements are often required.

In this embodiment, the hanger rod body 1 is further sleeved with an anchor pad 5, and the anchor pad 5 is located between the nut 4 and the upper distribution beam/the lower distribution beam. As a specific implementation form, the anchor backing plate 5 is a flat plate with an inner circle and an outer square. Since the load of the hanger rod body 1 is particularly large, if the anchor backing plate 5 is not added, the nut 4 and the first thread section 2 of the hanger rod body 1 can be subjected to very large pressure only by matching with the upper distributing beam to hoist the lower distributing beam and the front lower cross beam (less, more than ten tons). After the anchor backing plate 5 is additionally arranged, all pressure is inevitably shared due to the large surface of the anchor backing plate 5, the pressure in a unit area is reduced, and further the pressure born by the nut 4 and the first thread section 2 can be reduced.

In this embodiment, the nut 4 is not a conventional nut, but is specifically machined according to the thread structure of the threaded section of the hanger rod body 1. The nut 4 can be provided with a fastening structure on the same section, so that the operation of constructors can be facilitated, the fastening structure can be a common nut structure similar to an external hexagon, but a large wrench matched with the nut 5 needs to be specially manufactured due to the large size of the nut.

Therefore, in order to facilitate the mounting and dismounting of the nut 4, as shown in fig. 3, at least two turning handles 6 are provided on the outer circumference of the nut 4, and a construction worker can directly turn the nut 4 using a hand or other force applying rod, etc. directly by turning the turning handles 6. Simultaneously, in order to further make things convenient for hand or application of force pole operation, seted up gripping hole 7 on rotating handle 6, will apply force the pole disect insertion gripping hole 7 in or the direct gripping of hand, all can rotate nut 4, convenient operation can effectively improve work efficiency.
