Embodiment Construction
[0036] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0037] see Figure 1-Figure 14 , a steel tube concrete truss composite beam with a replaceable bridge deck, comprising a steel tube truss 1 . The structure of steel pipe truss 1 is well known to those skilled in the construction field. It is a structure formed by connecting steel pipes with hinges at both ends. It is a plane or space structure with triangular units composed of straight rods, which includes two upper chords 1-1, a lower chord 1-2, several abdominal pipes 1-3 and upper flat pipe 1-4, the upper chord 1-1 and the lower chord 1-2 are parallel, and the lower chord 1-3 is connected to the upper chord 1-1 and the lower string pipe 1-2, and the upper flat pipe 1-4 is connected between the upper string pipes 1-1.

The invention relates to a concrete filled steel tube truss composite beam with detachable bridge deck slabs and a construction method thereof. The concrete filled steel tube truss composite beam is characterized by further comprising the plurality of detachable bridge deck slabs sequentially paved at the upper part of the steel tube truss along with the direction of a bridge, wherein upper bent tubes are arranged at the upper part of the steel tube truss, a plurality of connection board sets are fixed on the upper bent tubes, and the connection boards are provided with screw holes; positioning grooves in one-to-one correspondence with the plurality of connection board sets and anchoring holes in one-to-one correspondence with the screw holes are arranged at the lower part of the bridge deck slabs; and each two adjacent bridge deck slabs are anchored and connected via a gear deadbolts. According to the concrete filled steel tube truss composite beam with detachable bridge deck slabs provided by the invention, replacement of the bridge deck slabs is facilitated when the bright is in use, the construction cycle is shortened, the construction difficulty is reduced, the construction quality and personnel safety can be ensured, and the requirement on construction site can be reduced.
Description
technical field [0001] The invention belongs to the technical field of building construction, in particular to a steel pipe concrete truss composite beam with a detachable bridge deck and a construction method. Background technique [0002] Steel tube concrete truss composite beam is a new type of bridge structure, and this type of bridge has been built such as Ganhaizi Super Bridge. The self-weight of this type of bridge is about 50% less than that of the concrete girder bridge with the same span. While increasing the spanning capacity of the bridge, it can also reduce the engineering amount of the lower structure of the bridge. Therefore, this type of bridge has a good development prospect. [0003] At present, in the construction of space concrete truss composite beams at home and abroad, the steel pipe trusses are usually erected by dragging and segmental hoisting, and then concrete is injected into the upper and lower chord steel pipes of the steel pipe truss. After the...
