Description

Technical Field

[0001] The utility model belongs to the technical field of continuous beam construction equipment, and in particular relates to a ladder component of a continuous beam construction hanging basket. Background Art

[0002] Figure 1 The side view of a common continuous beam structure is shown. During construction, it is necessary to start from the 0# section on the left and gradually move to the right. During the construction process, a construction basket needs to be installed to provide a temporary construction platform for construction. During the construction process, the load-bearing truss of the construction basket is fixed on the already cast beam section. The load-bearing bottom basket is suspended by the suspender rod. The bottom formwork of the bridge can be installed on the load-bearing bottom basket. In order to facilitate the construction of workers, a ladder is often required between the load-bearing truss and the load-bearing bottom basket. Figure 1 It can be seen that during the construction to the right, the bottom contour of the continuous beam gradually tilts upward for a distance, and the construction basket needs to be moved to the right step by step. The distance between the load-bearing truss and the load-bearing bottom basket is gradually reduced, so it is necessary to adjust the model of the ladder in time. Every time the construction basket moves to the right, a new model of ladder needs to be replaced. In this way, multiple models of ladders need to be processed during the construction process, and multiple models of ladders consume more production resources during processing, transportation and storage; in addition, the ladder needs to be replaced after each construction distance, which increases the complexity of the construction operation.

[0003] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0027] The utility model provides a ladder assembly for a continuous beam construction hanging basket, which is achieved by hingedly connecting the top of the ladder with the load-bearing truss of the construction hanging basket, and then arranging a vertical connecting frame and a transverse supporting rod for supporting the ladder under the load-bearing truss, and by adjusting the height of the transverse supporting rod to change the inclination angle of the ladder, the ladder can adapt to the adjustment of the distance between the load-bearing truss and the load-bearing bottom basket at any time.

[0028] like Figure 2-4 As shown, the ladder assembly of the continuous beam construction hanging basket includes a construction hanging basket 1, which provides a temporary construction platform to facilitate construction. The construction hanging basket 1 has a load-bearing truss 101 and a load-bearing bottom basket 102. The load-bearing truss 101 is installed on the top of the beam section of the continuous beam 3 that has been cast, and the load-bearing bottom basket 102 is suspended and hoisted at the bottom of the load-bearing truss 101. A ladder 2 is arranged between the load-bearing truss 101 and the load-bearing bottom basket 102. The top of the ladder 2 is hinged to the load-bearing truss 101 through a pin 4. A vertical connecting frame 103 is fixedly arranged at the bottom of the load-bearing truss 101. The vertical connecting frame 103 has a plurality of vertically fixed adjustment rods 1031. In order to ensure the stability of the adjustment rods 1031, a reinforcing connecting rod 1032 can be arranged between two adjacent adjustment rods 1031. A transverse support rod 104 is movably provided on the vertical connecting frame 103. The installation height of the transverse support rod 104 can be changed by moving the installation position of the transverse support rod 104 on the vertical connecting frame 103. The end of the transverse support rod 104 away from the continuous beam 3 is arranged under the ladder 2 to support the ladder 2. In this way, when working, the inclination angle of the ladder 2 can be changed by adjusting the height of the transverse support rod 104, so that the ladder 2 can adapt to the adjustment of the distance between the load-bearing truss 101 and the load-bearing bottom basket 102.

[0029] Specifically, the ladder assembly of the continuous beam construction hanging basket also includes a displacement adjustment structure for adjusting the connection position between the lateral support rod 104 and the vertical connecting frame 103. By operating the structure, the installation height of the lateral support rod 104 can be easily adjusted.

[0030] like Figure 3 , Figure 5As shown, the adjustment rod 1031 is provided with a vertically arranged strip hole 105, and the transverse support rod 104 is provided with a through hole 106 corresponding to the strip hole 105 at intervals, and the transverse support rod 104 and the adjustment rod 1031 are fixedly connected through the strip hole 105 and the through hole 106 via a detachable connecting component, and the strip hole 105, the through hole 106 and the detachable connecting component constitute the above-mentioned displacement adjustment structure. In this way, when the through hole 106 corresponds to different positions of the strip hole 105, the transverse support rod 104 is correspondingly arranged at different heights.

[0031] In this embodiment, the detachable connection assembly includes a connection bolt 107 and a connection nut 108, and the connection nut 108 is threadedly connected to the connection bolt 107. In other embodiments, other common detachable connection assemblies may also be used.

[0032] Furthermore, in order to increase the contact area between the transverse support rod 104 and the ladder 2, increase the support stability of the transverse support rod 104, and reduce the damage of the transverse support rod 104 to the surface coating of the ladder 2, a support structure is provided on the transverse support rod 104. The support structure has a support surface, and the support surface is used to support the side facing the ladder 2.

[0033] In this embodiment, the supporting structure is a support plate 109, the length of the support plate 109 is greater than the width of the ladder 2, so as to fully support the ladder 2 from the bottom of the ladder 2. The support plate 109 forms the above-mentioned support surface on one side facing the ladder 2, and the support surface is used to abut against the lower side of the supporting ladder 2. In order to allow the support plate 109 to adjust the inclination angle following the ladder 2, the support plate 109 is hinged to the transverse support rod 104.

[0034] Furthermore, in order to ensure the safety of the ladder 2 , handrails 201 are fixedly provided on both sides of the ladder 2 .

[0035] In this embodiment, the transverse support rod 104 and the adjustment rod 1031 are both channel steel. The cross-sectional shape of the channel steel is a channel shape, so that the channel steel not only has high strength and rigidity, but also can bear a large load, and also has a light weight. Compared with other steel materials, it can reduce the dead weight of the building structure and reduce the cost of the building.

[0036] Specifically, during the construction process, after completing the construction of a beam section, the construction hanging basket 1 is moved forward. Before adjusting the load-bearing bottom basket 102 upward, the lateral support rod 104 can be adjusted upward first to increase the inclination angle of the ladder 2, and then the load-bearing bottom basket 102 is adjusted to meet the construction requirements.

[0037] In this way, there is no need to produce multiple models of ladders 2, which effectively reduces construction costs, and the inclination angle of the ladder 2 can be adjusted simply by adjusting the height of the lateral support rod 104, so that the ladder 2 meets the use requirements, reduces the difficulty and complexity of operation, and improves operating efficiency.

[0038] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
