Description
Technical Field
The utility model belongs to the technical field of city utility tunnel construction, in particular to utility tunnel buried bolt fastening tool in advance.
Background
In the city utility tunnel work progress, pre-buried bolt in advance usually for later stage installing support and lay all kinds of municipal pipelines. The number of the embedded bolts is large, and the embedded bolts are only fixed by common nuts on the inner side and the outer side of the template in the prior art for reinforcing the embedded bolts. But in later stage concrete placement process, the impact when the concrete is emptyd and the vibration when the concrete vibrates all easily make buried bolt disturbance in advance, cause buried bolt slope, displacement etc. in advance, lead to utility tunnel buried bolt installation qualification rate low in advance, effective rate of utilization is low, has seriously influenced later stage efficiency of construction, has increased cost of maintenance.
Disclosure of Invention
The to-be-solved problem of the utility model is to overcome the not enough of background art, provide a utility tunnel buried bolt in advance reinforcement instrument.
The invention is realized by the following technical scheme:
the utility model provides a utility tunnel embedded bolt reinforcement instrument, includes the nut that matches with embedded bolt, the wing is consolidated to a plurality of nut body coupling, the bottom face of consolidating the wing flushes with the bottom face of nut, and the peak of consolidating the wing with the nut junction is located the top below of nut.
Preferably, the upper surface of the reinforcing wing is a curved surface gradually decreasing in height from the nut to the outside.
Preferably, the number of the reinforcing wings is 3, and the reinforcing wings are uniformly distributed on the periphery of the nut.
Preferably, the reinforcing wings of the nut periphery are connected together.
Preferably, the horizontal length of the reinforcing wing from the outside of the nut is 3 to 4 times the outer diameter of the nut.
Preferably, the reinforcement wing is welded to the nut.
Preferably, the reinforcing wing is made of stainless steel.
Preferably, the distance from the highest point of the reinforcing wing at the joint of the reinforcing wing and the nut to the top end of the nut is 0.5-2 cm.
The utility model has the advantages that: the utility model discloses strengthening tool greatly increased when consolidating to buried bolt's about the power, strengthened buried bolt's reinforcement effect in advance, make buried bolt in advance can resist the disturbance of concrete placement in-process and can not take place the skew, guaranteed later stage support mounting qualification rate. The utility model discloses instrument simple structure, easy to process, the practicality is strong, the cost of the renovation of pre-buried bolt later stage that has significantly reduced.

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 derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a comprehensive pipe gallery embedded bolt reinforcing tool, which is obtained by improving a nut 1 for locking an embedded bolt and modifying the nut into the reinforcing tool. Specifically, a plurality of reinforcing wings 2 are uniformly and outwardly arranged on one circle of the nut 1, the bottom end surfaces of the reinforcing wings 2 and the bottom end surface of the nut 1 are on the same horizontal plane, the highest point of the reinforcing wing 2 connected with the nut 1 is located below the top end of the nut 1, namely, the height of the reinforcing wing 2 is lower than that of the nut 1, so that the whole reinforcing tool can be reinforced by using an original tool, for example, an original wrench for screwing the nut 1 can be used for reinforcement. Preferably, the highest point of the reinforcing wing 2 at the joint with the nut 1 is 0.5-2cm away from the top end of the nut 1, i.e. a 0.5-2cm wrench operating space is left at the upper part of the nut 1 for screwing or unscrewing the reinforcing tool of the present invention. Of course, a special operating tool can be made to operate.
The reinforcing wing 2 may be integrally formed with the nut 1 during machining, or the reinforcing wing 2 may be welded to the nut 1 for one turn at a later stage. The reinforcing wings 2 of the present embodiment are preferably in a stable triangular structure, the number of the reinforcing wings 2 is three, and the three reinforcing wings are uniformly distributed on the nut 1 for one circle, as shown in fig. 1, and the upper surface of the reinforcing wing 2 is a curved surface gradually decreasing from the nut 1 to the outside, that is, the thickness of the reinforcing wing 2 near the nut 1 is greater than that of the reinforcing wing 2 far from the nut 1. The three reinforcing wings 2 are selected, so that the stability is ensured, materials for the reinforcing wings 2 are saved, the cost is saved, the materials can be further saved when the stability is ensured due to the design of gradual change of the thickness, and the thickness is the thickest due to the fact that the stress around the nut 1 is the largest.
In order to make the reinforcement wing 2 more stable, it is preferable that the reinforcement wing 2 on the periphery of the nut 1 is designed to be connected together, that is, the reinforcement wing 2 adjacent to the nut 1 is connected together and separated from the nut 1.
As a further preferable scheme, the reinforcing wing 2 is made of stainless steel material, and the horizontal length of the reinforcing wing 2 from the nut 1 to the outside is 3-4 times of the outer diameter of the nut 1. Therefore, the contact area between the reinforcing tool and the template is fully ensured, and the force is transmitted to the template through a large contact surface after the embedded bolt is impacted, so that the offset of the embedded bolt is effectively avoided, and the installation qualified rate of the embedded bolt is greatly increased.
When the invention is used: after the embedded bolt penetrates through the outer side of the template, the reinforcing tool is screwed on the embedded bolt on the outer side of the template, when the embedded bolt is screwed, the bottom end face of the nut 1 contacts the outer side of the template, and then the nut 1 is screwed by a wrench. When the template is dismantled, the reinforcing tool is dismantled and properly stored for subsequent recycling, and then the template is dismantled.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
