Description
Technical Field
The utility model relates to a civil air defense engineering technical field especially relates to a civil air defense engineering floor structure.
Background
The civil air defense is measures and actions which are taken by governments to mobilize and organize people for preventing enemy air attacks and eliminating consequences, and is called civil air defense for short. The air defense system is a soil air defense system formed by air defense and field operation air defense together, and is an important component of modern national defense.
The civil air defense project is an underground protective building which is independently built for guaranteeing shelter of war personnel and materials, command of civil air defense and medical aid, and a basement which is built by combining ground buildings and can be used for air defense in war.
Civil air defense engineering is different from ordinary basements. The common basement is built for stabilizing the above-ground building or realizing a certain purpose, and has no protection grade requirement; the air defense basement is specially designed according to the protection requirements of civil air defense engineering. The top plate, the side wall and the floor of the civil air defense basement are thicker and firmer than the common basement, and have certain shock wave resistance and conventional bomb detonation wave resistance besides bearing.
The civil air defense engineering bottom plate is laid on the grade beam more, form a complete bottom plate structure, as shown in fig. 1, partial construction site is in the bottom plate work progress, put bottom plate upper portion reinforcing bar and pass on the reinforcing bar of grade beam upper portion, make bottom plate and grade beam can't form effectual combination, what the civil air defense bottom plate bore is the power that water buoyancy and civil air defense bottom plate equivalent load transmitted, and these two kinds of effort are all from up down, not only lead to the power of bottom plate can't pass the grade beam, still can cause the fracture to the bottom plate.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an invention aim at provides a civil air defense engineering bottom plate structure, adopts the utility model provides a technical scheme has solved the technical problem that the power that has the bottom plate in current bottom plate structure can't transmit to the grade beam and the bottom plate is cracked easily.
In order to solve the technical problem, the utility model provides a civil air defense engineering bottom plate structure, which comprises a ground beam and a bottom plate poured above the ground beam; before the bottom plate is poured, strip-shaped plate steel bars are uniformly paved in a direction perpendicular to the length direction of the ground beam; and opening stirrups are vertically arranged on the plate reinforcing steel bars in a spanning manner, and two legs of each opening stirrup are anchored into the ground beam.
Preferably, the open stirrups simultaneously straddle a plurality of the plate reinforcing steel bars.
Preferably, a plurality of the opening stirrups are arranged side by side along the width direction of the ground beam, and two adjacent opening stirrups are staggered along the length direction of the ground beam.
Preferably, at least one plate reinforcing steel bar is arranged below two adjacent open stirrups.
Preferably, the two legs of the open stirrup are anchored into the ground beam by 0.3-0.7 m.
From the above, use the utility model discloses can obtain following beneficial effect: through anchor opening stirrup on the grade beam to this opening stirrup strides and locates on the slab reinforcement, make bottom plate and grade beam effectively combine to form a whole after pouring, the bottom plate can transmit two kinds of power to the grade beam when bearing the power that water buoyancy and civil air defense bottom plate equivalent load transmitted, avoids the bottom plate fracture to damage.
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 of the present invention or the prior art will be briefly described below. It is obvious that the drawings in the following description are only some embodiments of the invention, and that for a person skilled in the art, other drawings can be derived from them without inventive faculty.
FIG. 1 is a side view of a prior art civil air defense construction base plate structure along the length direction of a ground beam;
FIG. 2 is a side view of the bottom plate structure along the length direction of the ground beam according to the embodiment of the present invention;
fig. 3 is a top view of the embodiment of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The civil air defense engineering bottom plate is laid on the grade beam more, in the bottom plate work progress, puts bottom plate upper portion reinforcing bar and passes on grade beam upper portion reinforcing bar for bottom plate and grade beam can't form effectual combination, what the civil air defense bottom plate bore is the power that water buoyancy and civil air defense bottom plate equivalent load transmitted, and these two kinds of effort are all from up down, not only lead to the power of bottom plate can't pass the grade beam, still can cause the fracture to the bottom plate.
In order to solve the above technical problem, referring to fig. 2-3, the present embodiment provides a civil air defense engineering floor structure, which includes a ground beam 20 and a floor 10 poured over the ground beam 20. Before the bottom plate 10 is poured, long-strip-shaped plate steel bars 11 are uniformly paved in a direction perpendicular to the length direction of the ground beam 20.
In order to effectively combine the bottom plate 10 with the ground beam 20, the present embodiment vertically spans the open stirrups 21 on the plate steel bars 11 before the bottom plate 10 is poured, and both legs of the open stirrups 21 are anchored into the ground beam 20.
Specifically, the open stirrups 21 are arranged on the plurality of plate reinforcing bars 11 in a straddling manner. In the arrangement order, a plurality of open stirrups 21 are arranged side by side along the width direction of the floor beam 20, and two adjacent open stirrups 21 are arranged in a staggered manner along the length direction of the floor beam 20.
And in terms of construction parameters, two feet of the opening stirrup 21 are anchored into the ground beam 20 by 0.3-0.7 m. Preferably 0.5 m.
In summary, in the present embodiment, the opening stirrup 21 is anchored to the ground beam 20, and the opening stirrup 21 spans the slab reinforcement 11, so that the bottom plate 10 and the ground beam 20 are effectively combined to form a whole after pouring, and when the bottom plate 10 bears the force transmitted by the buoyancy of water and the equivalent load of the civil air defense bottom plate 10, the two forces can be transmitted to the ground beam 20, thereby avoiding the breakage and damage of the bottom plate 10.
As a further improvement of the technical solution, in the civil air defense engineering bottom plate 10 structure provided by the embodiment, at least one steel plate bar 11 is commonly present below two adjacent open stirrups 21.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
