Description
Technical Field
The utility model belongs to a raft upper portion steel bar support.
Background
As shown in fig. 1, in the raft reinforcement construction process, the upper reinforcing mesh of the raft foundation needs to bear the loads of the self weight of the reinforcement, a concrete pump pipe, constructors, small machinery and the like. However, because the upper mesh reinforcement 2 of the raft foundation and the lower mesh reinforcement 4 of the raft foundation have a large height difference, the stirrup 3 is needed to ensure the connection between the upper mesh reinforcement and the lower mesh reinforcement and ensure the strength and stability of the upper mesh reinforcement during the construction process. However, the traditional stirrup bar has poor supporting stability due to more uncertain factors of the thickness control of the upper reinforcing mesh protective layer, and the safety problems of collapse of the upper reinforcing mesh and the like easily occur; and the manufactured stirrup rib is time-consuming and labor-consuming, the material loss is large, and the engineering cost is greatly increased.
Disclosure of Invention
The utility model aims at designing a raft upper portion steel bar support can improve the intensity and the stability of upper portion reinforcing bar net, guarantees that every reinforcing bar of upper portion reinforcing bar net all has the strong point. The support structure has the advantages of simple structure, firm support, good stability, material saving and low construction cost.
For this reason, the utility model discloses a raft foundation, be the several anti-floating anchor that the spacing distance was equipped with perpendicular to raft foundation below raft foundation's elevation, every anti-floating anchor interpolation is equipped with the bracing piece arrangement of reinforcement that is T shape, the bracing piece arrangement of reinforcement comprises two steel arrangements of reinforcement, bracing piece arrangement of reinforcement lower part rigid coupling is in anti-floating anchor upper end, bracing piece arrangement of reinforcement upper end extends anti-floating anchor upper end and is parallel with raft foundation upper portion reinforcing bar net, two steel arrangements of reinforcement top that constitute the bracing piece arrangement of reinforcement in the every anti-floating anchor are buckled 90 to opposite direction, the section of buckling of two steel arrangements of reinforcement is parallel with raft foundation upper portion reinforcing bar net after buckling, it is integrative each other to be located between the section of buckling of two steel arrangements of reinforcement in adjacent two anti-floating anchors that are the spacing distance setting, the section of buckling of steel arrangement and reinforcing bar support crossbeam are through ligature or welded form and raft foundation upper portion reinforcing bar rigid coupling of reinforcing bar net.
The diameter of the bending section of the steel reinforcing bar is the same as that of the cross beam of the steel bar support.
Above-mentioned structural design has reached the utility model discloses a purpose.
The utility model discloses can improve the intensity and the stability of upper portion reinforcing bar net, guarantee that every reinforcing bar of upper portion reinforcing bar net all has the strong point. The support structure has the advantages of simple structure, firm support, good stability, material saving and low construction cost.

Detailed Description
As shown in fig. 1 to 3, a raft upper reinforcing steel bar support comprises a raft foundation 1, an upper reinforcing mesh 2 is arranged at the inner upper part of the raft foundation, and a raft lower reinforcing mesh 4 is arranged at the inner upper part. A plurality of anti-floating anchor rods 8 vertical to the raft foundation are arranged below the elevation of the raft foundation at intervals, and a T-shaped support rod reinforcing bar 5 is inserted in each anti-floating anchor rod. The supporting rod reinforcing bars are composed of two steel reinforcing bars, the lower parts of the supporting rod reinforcing bars are fixedly connected in the upper ends of the anti-floating anchor rods, and the upper ends of the supporting rod reinforcing bars extend out of the upper ends of the anti-floating anchor rods and are parallel to the reinforcing mesh on the upper part of the raft foundation. The two steel reinforcing bars forming the reinforcing bars of the support rod in each anti-floating anchor rod are bent 90 degrees in opposite directions, and the bent sections 51 of the two steel reinforcing bars are parallel to the reinforcing mesh on the upper part of the raft foundation. Two steel reinforcing bars at the lower section between the bending sections are connected into a welding part 7 through welding.
The bending sections of two steel reinforcing bars in two adjacent anti-floating anchor rods arranged at intervals are connected into a whole through a steel bar support crossbeam 6, and the bending sections of the steel reinforcing bars and the steel bar support crossbeam are fixedly connected with corresponding steel bars of a steel bar net on the upper part of a raft foundation in a binding or welding mode. The diameter of the bending section of the steel reinforcing bar is the same as that of the cross beam of the steel bar support. The bracing piece arrangement of reinforcement can play the effect of vertical braces to raft foundation. The steel bar support cross beam can connect the bending sections of the reinforcing bars of the adjacent support rods in series into a whole, so that the steel bars of each corresponding part of the upper steel bar mesh are guaranteed to have supporting points, and the overall strength of the upper steel bar mesh is improved. The safety problems that the upper reinforcing mesh of the traditional raft foundation is poor in supporting stability, the upper reinforcing mesh is prone to collapse and the like are solved.
In a word, the utility model discloses can improve the intensity and the stability of upper portion reinforcing bar net, guarantee that every reinforcing bar of upper portion reinforcing bar net all has the strong point. The support structure has the advantages of simple structure, firm support, good stability, material saving and low construction cost. Can be popularized and used.
