The utility model discloses a box culvert roof die block fixing device can generally use in the fixed of the small-size box culvert roof die block of different thickness, need not to set up the support in the work progress, has improved the efficiency and the security of construction.
Description
Technical Field
The utility model belongs to the technical field of municipal pipe network engineering, concretely relates to small-size box culvert roof die block fixing device.
Background
In municipal pipe network engineering box culvert work progress, the fixed of box culvert roof die block is mainly through setting up the support at the box culvert bottom plate with supporting, nevertheless to the local roof of the longer small-size box culvert of some length repair, adopts the fixed roof form of support method, and concrete placement accomplishes the back, need the manual work to get into and demolish the support in the box culvert, because the box culvert is longer, needs to trompil, ventilate the box culvert before the manual work gets into the box culvert, and there are toxic gas and other unclear risk factors in the box culvert. The method has the disadvantages of complicated field operation, long time, poor flexibility and poor economy, influences on-site construction progress and has certain risk factors.
Disclosure of Invention
The to-be-solved technical problem of the utility model is in the box culvert work progress, traditional support method complex operation is inefficiency, and has the potential safety hazard.
In order to solve the technical problem, the utility model provides a small-size box culvert roof die block fixing device, include: the steel pipe runs through the top plate, one end of the steel pipe is fixedly connected with the steel bar A, the two steel bars B are respectively and horizontally connected to the left side and the right side of one end of the adjusting bolt, and the other end of the adjusting bolt is connected with the inner wall of the steel pipe in a threaded fit mode.
Furthermore, two steel bars C are arranged between the two steel bars B and the adjusting bolt and are respectively and fixedly connected with the two steel bars B and the adjusting bolt.
Further, the lengths of the two steel bars B just reach the middle of the two channel steels on the top plate.
The utility model has the advantages that: through adjusting the adjusting bolts, the small box culvert top plate bottom die fixing device is suitable for box culvert top plates with different thicknesses; the channel steel is used as a stress device, the top plate bottom die is fixed on the channel steel through the top plate bottom die fixing device, a steel pipe support fixing template is not required to be erected on site, the condition that an operator enters a box culvert to support a die and detach the die is avoided, the condition that holes are formed in the box culvert and ventilation is avoided, and construction safety is improved; roof die block fixing device need not to set up the steel pipe support at the scene and fixes, and adjusting bolt can use repeatedly, has improved the efficiency of construction.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Fig. 1 is a schematic structural view (in use) of a small box culvert top plate bottom die fixing device of the present invention.
Figure 2 is the utility model discloses a structural schematic of small-size box culvert roof die block fixing device's steel pipe.
Fig. 3 is a schematic structural view of an adjusting bolt of the fixing device for the top plate and the bottom plate of the small box culvert of the present invention.
Fig. 4 is a schematic view of the use state (overlooking) of the small box culvert top plate bottom die fixing device of the present invention.
In the figure: the steel plate comprises 1-a steel pipe, 2-a steel bar A, 3-a steel bar B, 4-a steel bar C, 5-an adjusting bolt, 6-channel steel, 7-a box culvert top plate bottom formwork and 8-a top plate.
Detailed Description
In the description of the present invention, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may for example be fixedly connected, detachably connected, or integrally connected; they may be mechanically coupled, directly coupled, indirectly coupled through intervening media, or may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 1 to 4, a small box culvert top plate bottom die fixing device includes: steel pipe 1, reinforcing bar A2, two reinforcing bars B3, adjusting bolt 5, steel pipe 1 runs through roof 8, its one end and reinforcing bar A2 fixed connection, two reinforcing bars B3 are horizontal connection respectively in the left and right sides of 5 one ends of adjusting bolt, the other end of adjusting bolt 5 is connected with the screw-thread fit of 1 inner wall of steel pipe.
Preferably, two steel bars C4 are arranged between the two steel bars B3 and the adjusting bolt 5 and are respectively and fixedly connected with the two steel bars B3.
Preferably, the two reinforcing bars B3 have a length just reaching the middle of the two channel beams 6 on the top plate 8.
Before use, a 50 cm-long phi 100 thick-wall steel pipe is processed into a steel pipe 1, threads are processed in the length range of 30cm on the inner wall of one end of the thick-wall steel pipe, and a C20 thread steel bar (steel bar A2) with the length of 20cm is welded at the bottom of the thick-wall steel pipe to serve as a fixed end in contact with a top plate bottom formwork 7; then preparing a steel bar with the length of 40cm, processing the steel bar into an adjusting bolt 5, wherein the processing length of the thread of the steel bar is 30mm, and ensuring that the thread of the steel bar is matched with the thread inside the steel pipe 1 during processing; then welding two C20 twisted steel bars (steel bars B3) with the length of 50cm at the junction of the processing area and the non-processing area of the adjusting bolt 5 as the other fixed ends in contact with the channel steel 6; finally, two C8 twisted steel bars (steel bars C4) with the length of 5cm are respectively welded and fixed with the non-processing area on the adjusting bolt 5 and the steel bar B3.
During the use, at first, place channel-section steel 6 subaerial, then, pass roof die block board 7 with steel pipe 1 to through precession adjusting bolt 5, make reinforcing bar A2 and reinforcing bar B3 respectively with roof die block board 7 and channel-section steel 6 block, then pour the concrete to roof floor template 7, rethread reinforcing bar C4 back screwing out adjusting bolt 5 after the concrete placement is accomplished, at last, accomplish whole construction operation promptly to the slip casting maintenance in steel pipe 1.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made thereto within the knowledge of those skilled in the art.
