Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a beam bottom hanger construction platform. Background Art

[0002] A construction platform is a temporary platform that provides workspace and safety protection for construction workers on construction sites. It is usually constructed of steel pipes, steel plates and other materials, and can be cantilevered outside a building or in a high-altitude area to provide a stable working platform for construction workers.

[0003] During the process of bridge maintenance and reinforcement, it is often necessary to carry out construction work at the bottom of the beam. The project often uses a bridge inspection vehicle or sets up a support at the bottom of the beam as a construction platform for construction work at the bottom of the bridge. Bridge inspection vehicles are often used when the bridge clearance is high, it is not convenient to set up a support under the bridge, and the operation time is relatively short. In other cases, the support under the bridge is generally used for construction work; bridges often cross rivers and canyons, etc., and it is not convenient to set up a support under the bridge, so only a bridge inspection vehicle can be used to provide a construction work platform. However, since the construction time of bridge maintenance work is relatively long, using a bridge inspection vehicle as a construction platform for a long time will increase the construction cost. At the same time, the long-term occupation of the bridge deck by the bridge inspection vehicle brings great inconvenience to the bridge deck traffic. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For example, see Figure 1-3 As shown, the utility model is a beam bottom hanger construction platform, comprising a bridge deck stabilizing structure 1, a vertical connecting structure 2 and a bottom bearing structure 3, wherein the two vertical connecting structures 2 are detachably installed at both ends of the bottom bearing structure 3, and the bridge deck stabilizing structure 1 is detachably installed on one side of the top of the vertical connecting structure 2;

[0022] The ends of the bridge deck stabilizing structure 1 are welded with fixing parts, and the bridge deck stabilizing structure 1 is fixed on the beam through the fixing parts.

[0025] For example 2, please refer to Figure 1-5 As shown, the utility model is a beam bottom hanger construction platform, comprising a bridge deck stabilizing structure 1, a vertical connecting structure 2 and a bottom bearing structure 3, wherein the two vertical connecting structures 2 are detachably installed at both ends of the bottom bearing structure 3, and the bridge deck stabilizing structure 1 is detachably installed on one side of the top of the vertical connecting structure 2;

[0026] The ends of the bridge deck stabilizing structure 1 are welded with fixing parts, and the bridge deck stabilizing structure 1 is fixed on the beam through the fixing parts.

[0027] The inner sides of the two vertical connecting structures 2 are both provided with transverse supporting legs 4 .

[0028] A second platform is detachably installed between at least two beam bottom hangers. The second platform is composed of multiple steel pipes 7. The multiple steel pipes 7 are arranged in a straight line. Both ends of the steel pipes 7 are detachably installed on the bottom bearing structure 3 on the two beam bottom hangers.

[0029] The second platform and the bottom bearing structure 3 are both provided with bearing plates 5 .

[0030] The bridge deck stabilizing structure 1 is welded entirely with lightweight steel materials to reduce the deadweight of the structure, and is fixed with high-strength bolts 6 to the bridge deck.

[0031] The vertical connecting structure 2 is welded as a whole with lightweight steel materials to reduce the deadweight of the structure. Its upper part is welded and fixed to the bridge deck stabilizing structure 1, and its lower part is fixed to the bottom bearing structure 3 with high-strength bolts 6.

[0032] The bottom bearing structure 3 is welded with lightweight steel materials as a whole to reduce the deadweight of the structure. The left and right sides of the structure are connected and fixed with the vertical connecting structure 2 by high-strength bolts 6, and a simple paving layer 5 is laid on the surface to facilitate the movement of construction workers during construction work.
