Abstract
The utility model discloses an embedded hanging ring for a construction site civil air defense door, which comprises a Y-shaped embedded steel bar and a steel bar hanging ring embedded in a basement top plate, wherein the bottom of a straight line section of the Y-shaped embedded steel bar is provided with an external thread part, the top of the steel bar hanging ring is provided with a bulge, the bulge is provided with an internal thread hole, the Y-shaped embedded steel bar is in threaded connection with the steel bar hanging ring through the external thread part and the internal thread hole, the external thread part is embedded in the basement top plate, and the end parts of two inclined line sections of the Y-shaped embedded steel bar are respectively and fixedly connected with a steel bar bending fixing part. The embedded hanging rings can be recycled, the number of the hanging rings used in one project is greatly reduced, the used hanging rings can be still used in other projects, the material resource loss is reduced, and the environment-friendly effect is achieved; compared with the original structure, the material consumption of the steel bar is reduced to a certain extent, and the steel bar has economical efficiency.
Description
Technical Field
The utility model relates to the technical field of construction site civil air defense door installation, in particular to an embedded hanging ring for a construction site civil air defense door.
Background
Because of people's air defense door dead weight is too big, normally not be difficult to the installation with the help of handling instrument job site, be difficult to operate and have the potential safety hazard with the installation of other construction machinery (dig machine etc.), so when people prevent structure design generally can be at people's air defense door position pre-buried rings to people's air defense door hoist and mount construction.
Adopt traditional pre-buried rings (see figure 1) to construct the shortcoming:
the installation of people's air defense door is once only operation, can rings just place always after the construction finishes, can just use rings again when treating next maintenance people's air defense door, and the outstanding rings are not too pleasing to the eye during vacant, and probably can rust and corrode, will produce the potential safety hazard to the use when maintaining.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems and the defects in the prior art, the utility model provides a novel embedded hanging ring for a civil air defense door on a construction site, which has the advantages of controlling certain cost on the premise of meeting the safety, enabling the hanging ring to be recycled, reducing material loss, being green and environment-friendly, having small embedded exposed part, being not easy to damage and convenient for construction, customizing embedded by a civil air defense door installation unit and recycling the embedded ring.
The utility model solves the technical problems through the following technical scheme:
the utility model provides an embedded hanging ring for a construction site civil air defense door, which is characterized by comprising Y-shaped embedded steel bars and steel bar hanging rings embedded in a basement top plate, wherein the bottom of a straight line section of each Y-shaped embedded steel bar is provided with an external thread part, the top of each steel bar hanging ring is provided with a bulge, each bulge is provided with an internal thread hole, the Y-shaped embedded steel bars are in threaded connection with the steel bar hanging rings through the external thread parts and the internal thread holes, the external thread parts are embedded in the basement top plate in advance, and the end parts of two inclined line sections of each Y-shaped embedded steel bar are respectively and fixedly connected with a steel bar bending fixing part.
Preferably, two oblique line segments of the Y-shaped embedded steel bars are 120 °.
Preferably, the diameter of the hanging ring is 25 mm.
Preferably, the diameter of the straight line segment of the Y-shaped embedded steel bar is 25 mm.
On the basis of the common knowledge in the field, the above preferred conditions can be combined randomly to obtain the preferred embodiments of the utility model.
The positive progress effects of the utility model are as follows:
1. the embedded hanging rings can be recycled, the number of the hanging rings used in one project is greatly reduced, the used hanging rings can be still used in other projects, the material resource loss is reduced, and the environment-friendly effect is achieved.
2. Compared with the original structure, the material consumption of the steel bar is reduced to a certain extent, and the steel bar has economical efficiency.

Fig. 2 is a schematic structural view of an embedded hanging ring for a civil air defense door in a construction site according to a preferred embodiment of the utility model.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 2, this embodiment provides an embedded rings for job site people's air defense door, and it includes Y type embedded reinforcement 1 and pre-buried reinforcing bar rings 2 in basement roof 3, the bottom of the straightway of Y type embedded reinforcement 1 is equipped with external screw thread portion, reinforcing bar rings 2's top is equipped with protruding 4, the internal thread hole has been seted up on protruding 4, through external screw thread portion and internal thread hole threaded connection so that Y type embedded reinforcement 1 and reinforcing bar rings 2 looks spiro union, external screw thread portion buries in the basement roof in advance, two slash sections of Y type embedded reinforcement 1 are 120, the tip difference fixedly connected with reinforcing bar bend-up mounting 5 of two slash sections of Y type embedded reinforcement 1.
The embedded steel bars are changed into Y-shaped, so that small part of oblique section bearing capacity is provided for the top plate of the basement on the premise of meeting the tensile stress of hoisting construction, the plate outlet part adopts a bolt form, the hanging ring can be installed again during hoisting construction, and the hanging ring can be detached and used in other positions after the construction is finished.
The straight line section of the Y-shaped embedded steel bar and the steel bar hanging ring both adopt steel bars with the diameter of 25, and the total tensile stress area of the original structure is 800mm2The total tensile stress area of the novel belt is 625mm2If the structure is continuously loaded, the stress of the structure is weaker than that of the original structure, but the structure participates in one-time construction load, and the hanging ring is locally reinforced, so that the stress of the structure is relatively reinforced in actual use compared with that of the original structure. When the practical design is used, the specific diameter of the steel bar is determined by calculation after the civil air defense door load is determined.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the utility model, and these changes and modifications are within the scope of the utility model.
