Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering construction, in particular to an assembled simple bridge frame. Background Art
[0002] During the construction process, it is often necessary to temporarily cross spatial obstacles such as foundation pits, trenches, and corridors. In order to achieve crossing, the current construction sites mostly use methods such as "ladders and planks", "scaffolding + planks", etc. The "ladders and planks" solution is often difficult to ensure the safety of passage, and the "scaffolding + planks" solution will form new obstacles to the space below due to the scaffolding, and its applicability is limited. If a temporary bridge is specially built, it will be time-consuming and labor-intensive, and after the project is completed, the temporary bridge will generally be abandoned. Therefore, the cost of this solution is high and the efficiency is relatively low, and it is generally only used in larger projects. Utility Model Content

[0005] The longitudinal joints of the four-way reducer and the three-way reducer are both connected with longitudinal rods, and the transverse joints of the four-way reducer and the three-way reducer are both connected with transverse rods;
[0006] Vertical joints of the four-way reducer and the three-way reducer are both connected with vertical poles.
[0007] Preferably, the longitudinal rods, transverse rods, four-way reducers and three-way reducers form a frame structure.
[0008] Preferably, a connecting screw 1 is threadedly installed on one end of the transverse rod, and a short tube 1 is threadedly connected to the connecting screw 1.

[0010] Preferably, the longitudinal rods, transverse rods and vertical rods are all made of steel.
[0011] Preferably, the four-way reducer and the three-way reducer are both threadedly connected to the longitudinal rod, the transverse rod and the vertical rod.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The bridge structure of this scheme is extremely simple, consisting of only two types of components: steel pipes and pipe joints. It is simple to manufacture and low in cost.
[0014] 2. The main components of this solution are all made of steel, and the specifications of the components are determined by calculation, so they are safe to use.
[0015] 3. The size of the bridge in this scheme can be adjusted according to needs. The length can be adjusted by the number of assembled units, and the width, height, etc. can be adjusted by adding short sections.
[0016] 4. The bridge components of this solution are connected by threads without the help of other external fasteners, so the assembly is simple and the use is reliable.
[0017] 5. The bridge frame of this scheme is in the state of parts before assembly or after disassembly after use, with small size and convenient storage and transportation.
[0018] 6. If any component of the bridge in this solution is damaged, it can be replaced with a similar component, and there will be no situation where the entire bridge is scrapped due to damage to a local component. BRIEF DESCRIPTION OF THE DRAWINGS
