Abstract
The utility model discloses a main assembling jig frame for a large-span steel structure roof primary truss. The main assembling jig frame comprises a concrete foundation, reinforced concrete posts, lattice type steel frames, a lower chord bracing beam and pipe brackets. The main assembling jig frame is characterized in that the concrete foundation and the reinforced concrete posts are connected into one, the lower portions of the inner sides of the two reinforced concrete posts are of bracket shapes, the lower chord bracing beam is arranged on the protruding portions of two brackets in a shelving mode and provided with the lattice type steel frame, the lattice type steel frames are provided with the pipe brackets used for containing lower portion round chord members, embedded steel plates are embedded in the upper ends of the two reinforced concrete posts, and the lattice type steel frames are installed on the embedded steel plates and provided with the pipe brackets used for containing a left top chord member and a right top chord member. The main assembling jig frame has the advantages of being simple and reasonable in structure and convenient to operate, enabling large-span steel structure roof primary truss main assembly to be correct and fast to locate, and improving the labor efficiency and the construction quality.
Description
Technical field
The utility model relates to technical field of building construction, relates in particular to the total assembled moulding bed of a kind of large span steel structure roof main couple.
Background technology
Along with social progress, steel work is widely used under construction, large span steel structure roof system because of its moulding plasticity strong, outward appearance is graceful, more be widely used in large span public building, the common single-piece of its large span steel structure roof main couple, at produce in factory, to the job site section of being assembled into, is more always dressed up the truss that meets lifting requirements by section, truss general assembly beam volume is large, waste time and energy, work effect is low, and size is difficult control also.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provide a kind of Large span steel structure roof lid main couple total assembled moulding bed, make the total assembled location of large span steel structure roof main couple correct, quick, and the work effect that has solved prior art existence is low, the unmanageable problem of size.
The purpose of this utility model is achieved in that the total assembled moulding bed of a kind of large span steel structure roof main couple, comprise concrete foundation, reinforced concrete post, Strength calculation, lower edge brace summer and conduit saddle, it is characterized in that: concrete foundation is connected with reinforced concrete post, two reinforced concrete post lower inside are bracket shape, lower edge brace summer is shelved on above two outstanding positions of bracket, on lower edge brace summer, Strength calculation is installed, on Strength calculation, is provided with for placing the conduit saddle of bottom circle chord member; Two reinforced concrete post upper ends are buried pre-embedded steel slab underground, and Strength calculation is installed on pre-embedded steel slab, are provided with for placing respectively the conduit saddle of upper left quarter and upper right quarter circle chord member on Strength calculation.
The design of moulding bed and layout are determined according to the segmentation situation of main couple and the position of waypoint, want simultaneously considering of truss segmentation place round chord member up and down interface and for linking web member assembled of round chord member, neutral is set in the middle of cleaved facet, to reserve welding space.
During use, left part on truss, upper right part circle chord member are placed on the conduit saddle on Strength calculation, bottom circle chord member is placed on the conduit saddle on lower edge brace summer, and adjusts size, then by the firm welding on request of the web member for linking round chord member.
Compared with prior art, the utility model has the advantages that: simple and reasonable for structure, easy to operate, make the total assembled location of large span steel structure roof main couple correct, quick, improved efficiency and construction quality.
Accompanying drawing explanation
Fig. 1: the utility model is used schematic diagram.
In figure: 1, concrete foundation 2, reinforced concrete post 3, Strength calculation 4, lower edge brace summer 5, conduit saddle 6, circle chord member 7, web member.
The specific embodiment
For further describing the utility model, below in conjunction with embodiment and accompanying drawing, the utility model is further described.
As shown in the figure, the total assembled moulding bed of a kind of large span steel structure roof main couple, comprise concrete foundation 1, reinforced concrete post 2, Strength calculation 3, lower edge brace summer 4 and conduit saddle 5, it is characterized in that: concrete foundation 1 is connected with reinforced concrete post 2, two reinforced concrete post 2 lower inside are bracket shape, lower edge brace summer 4 is shelved on above two outstanding positions of bracket, Strength calculation 3 is installed on lower edge brace summer 4, on Strength calculation 3, is provided with for placing the conduit saddle 5 of bottom circle chord member 6; Two reinforced concrete post 2 upper ends are buried pre-embedded steel slab underground, and Strength calculation 3 is installed on pre-embedded steel slab, are provided with for placing respectively the conduit saddle 5 of upper left quarter and upper right quarter circle chord member 6 on Strength calculation 3.
The design of moulding bed and layout are determined according to the segmentation situation of main couple and the position of waypoint, want simultaneously considering of truss segmentation place round chord member 6 up and down interface and for linking web member 7 assembled of round chord member 6, neutral is set in the middle of cleaved facet, to reserve welding space.
During use, left part on truss, upper right part circle chord member 6 are placed on the conduit saddle 5 on Strength calculation 3, bottom circle chord member 6 is placed on the conduit saddle 5 on lower edge brace summer 4, and adjusts size, then by the firm welding on request of the web member 7 for linking round chord member 6.
