[0006]

By the way, there are many joints of fasteners in a unit-type building, and it is very complicated to check whether all of these joints are securely joined by fasteners. there were. In particular, if the fastener is damaged, after joining other fasteners, the fastener may be removed from the spare fastener storage area and joined, and for this reason,
Since the worker may forget to fasten the fastener, it is necessary to strictly check the joints, and there is a problem that the work is complicated.

In addition, conventional fasteners are put together in bags, including spare fasteners, and unused spare fasteners may be discarded together with other waste, resulting in waste. There was also a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for managing a fastener for a building unit and a spare fastener box which can easily confirm whether a required number of fasteners are used, reduce the checking work, and eliminate waste of the fastener. Is to provide.

[0009]

The present invention will be described with reference to the drawings. The present invention relates to a method for managing a fastener for a building unit used for joining building units constituting a unit building, which is required when building. A minimum number of necessary fasteners 10 are shipped together with the building units 2, while a spare fastener box 20 containing a spare fastener 30 is prepared at the site 3, and the fastener 10 damaged during the joining operation is replaced with the spare fastener. After the completion of the joining operation, the number of the fasteners 10 that have been damaged and the number of the spare fasteners 30 used are the same.

According to the present invention, the minimum required number of fasteners 10 are shipped together with the building unit 2.
Only, since the spare fastener 30 is stored in the spare fastener box 20, the spare fastener 30 not used can be easily collected together with the spare fastener box 20 without being discarded. The waste of the fastener 30 can be eliminated.

When the fastener 10 is damaged, the number of damaged fasteners 10 and the spare fastener box 2
Since the number of fasteners 30 taken out from 0 and used is compared and confirmed, for example, the number of spare fasteners 30 used is smaller than that of the damaged fastener 10, that is, there is an unjoined portion. Can be easily grasped, and each joint can be surely joined, and the checking operation can be easily performed.

In the present invention, the spare fastener 30 housed in the spare fastener box 20 includes an anchor bolt 31, a guide pin 32, and bolts 33 and 34.
And the nut 35 are preferable. If the various fasteners 30 used for joining these building units 2 are stored in the spare fastener box 20, for example, about one to two spare fastener boxes 20 may be brought into a construction site, and various fasteners may be used. The preparation work is simpler than in the case where each of the fasteners 30 is stored in a different spare fastener box for each type, and each fastener 3
0 can be easily performed.

At this time, the number of use of the spare fasteners 30 may be determined based on the number of fasteners 30 left in the spare fastener box 20. If the number of fasteners 30 left in the spare fastener box 20 is counted after the joining is completed, the number of fasteners used can be reliably determined by comparing the number of fasteners 30 in the spare fastener box 20 first.

The spare fastener box 20 has a holding portion 23 formed for each fastener 30,
27, the fasteners 30 are previously arranged without gaps in the holding portions 23, 27, and the number of the spare fasteners 30 to be used may be determined based on the space of the holding portions 23, 27 after the joining operation is completed. . In this case, after joining is completed, the number of used fasteners can be grasped only by looking at the spare fastener box 20, and the number of used spare fasteners 30 can be checked very easily.

At this time, the spare fastener box 20
The damaged fastener 10 may be arranged in the holding portions 23 and 27. By doing so, the damaged fastener 1
0 are sequentially arranged in the holding units 23 and 27, and the holding units 23 and 27
If there is a damaged fastener 10 that cannot be arranged at the same location, it can be easily grasped that no alternative spare fastener 30 is provided at the joint of the fastener 10. Further, if the holding portions 23 and 27 are not completely filled and a gap is not generated when the spare fastener 30 is arranged, the damaged fastener 10 and the used spare fastener 30 are used.
It can be easily grasped that the number of pieces is the same. Therefore,
The number of damaged fasteners 10 and the number of spare fasteners 30 used can be compared very easily.

The spare fastener box 20 according to the present invention comprises:
In a unit type building constructed by joining a plurality of building units 2 using fasteners 10, a spare fastener box 20 containing spare fasteners 30 of the fasteners 10 required for construction, wherein the fasteners 30
And holding portions 23 and 27 formed in accordance with the type of are provided.

The holding part 2 is attached to the spare fastener box 20.
When the fasteners 3 and 27 are provided, the number of fasteners 30 in the spare fastener box 20 can be kept constant by arranging the various fasteners 30 in the holding portions 23 and 27 without gaps.
Preparation work of the spare fastener box 20 becomes very simple. Further, when the spare fastener 30 is used in place of the damaged fastener 10, after the joining is completed, the spare fastener box 20 is viewed, that is, the holding portions 23, 27
The number of used fasteners can be ascertained only by looking at the gap portion, and the number of spare fasteners 30 used can be checked very easily.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a building unit 2 manufactured in a factory 1 is shipped to a building site 3 together with a minimum number of fasteners 10. On the other hand, the construction worker at the site brings the spare fastener box 20 containing the spare fastener 30 to the construction site.

Are formed in accordance with the shapes of the anchor bolts 31, the guide pins 32, and the high-strength bolts 33. For example, the holding portion 23A for the anchor bolt 31 is
The length of the anchor bolt 31 is the same as the length of the anchor bolt 31, and the width of the anchor bolt 31 is five, for example. Therefore, if the anchor bolt 31 is taken out and used, a gap is generated in the holding portion 23A, and the number of used bolts can be easily grasped.

Similarly, the holding portion 23B for the guide pin 32
Also, the vertical dimension is set to the length of three guide pins 32, and the width is set to the width of five guide pins. The holding portions 23C for the high-strength bolts 33 are formed for each of the bolts 33, and are configured such that each holding portion 23C can hold one bolt 33.

On the other hand, a handle 26 is attached to the upper part of the inner box 25, and holding parts 27 for the fasteners 30 such as bolts 34 and nuts 35 are formed. For example, the holding portions 27A for the bolts 34 are formed for each of the bolts 34 and are configured to hold one bolt 34, respectively. The holding portion 27B for the nut 35 is formed in a long groove shape, and is formed so that a predetermined number of nuts 35 are arranged in a line.

At the construction site, each worker performs a joining operation using the fastener 10 shipped together with the building unit 2. At this time, if the screw portion of each fastener 10 is crushed during the joining operation, the spare fastener 30 is taken out from the spare fastener box 20 and used.
The damaged fastener 10 may be collected in one place.

When all the joining operations are completed, the operator compares the number of the damaged fasteners 10 with the number of the fasteners 30 used from the spare fastener box 20. As a comparison method, the number of broken fasteners 10 for each type is counted, and the number of used fasteners 30 of the spare fastener box 20 is determined by, for example, checking the gaps in the holding portions 23 and 27, or determining the number of remaining fasteners. What is necessary is just to count the number of the fasteners 30 thus obtained, and compare the numbers.

If there is a difference between the number of the damaged fasteners 10 and the number of the used spare fasteners 30, each joint is checked again, and if there is any unjoined part, the part is joined using the fastener 30. .

When the number of the damaged fasteners 10 and the number of used spare fasteners 30 match, the joining operation is completed, and the unused spare fasteners 30 are brought back together with the spare fastener box 20. Then, the spare fastener box 20 may be supplemented with the used amount and brought to the next on-site work.

According to this embodiment, the following effects can be obtained. 1) While the minimum required fastener 10 is shipped together with the building unit 2, the spare fastener box 20 is prepared. Therefore, even if the fastener 10 is damaged, various fasteners 30 stored in the spare fastener box 20 can be stored. Can be used to perform the joining operation. As described above, since the spare fastener 30 is stored in the spare fastener box 20, the spare fastener 30 not used can be easily collected together with the spare fastener box 20, and the unused spare fastener 30 is discarded. Therefore, waste of the fastener 30 can be eliminated, and the cost of the fastener 30 can be reduced.

2) When fastener 10 is damaged, the number of damaged fasteners 10 and spare fastener box 20
Since the number of fasteners 30 taken out from the apparatus and used is compared and confirmed, the presence or absence of an unjoined portion can be easily grasped. For this reason, forgetting to fasten the fastener 30 at each joint can be reliably eliminated, the work of checking each joint can be easily performed, and the on-site construction work can be reduced.

3) The spare fastener box 20 is provided with holding portions 23 and 27 formed in accordance with the respective fasteners 30, and the holding portions 23 and 27 are provided with no gaps between the fasteners 30 and 27.
Is arranged, only after looking at the inside of the spare fastener box 20 after the joining operation is completed,
The number of spare fasteners 30 to be used can be easily determined only by grasping the existence degree of the 27 empty spaces, and the checking workability can be further improved.

4) Since the spare fastener box 20 is formed so as to be separable into two parts, a box body 21 and a middle box 25, and holding portions 23 and 27 are formed respectively. By arranging the fasteners 30 side by side, the state (such as the number) of the stored fasteners 30 can be easily visually recognized, and a large number of fasteners 30
Can be stored in the spare fastener box 20 and carried.

It should be noted that the present invention is not limited to the above embodiments, but includes other configurations that can achieve the object of the present invention, and the following modifications are also included in the present invention. For example, the method for comparing the number of damaged fasteners 10 and the number of used spare fasteners 30 is not limited to the above-described embodiment, and the damaged fasteners 10 may be returned to the spare fastener box 20 and damaged incapable of being stored in the spare fastener box 20. The determination may be made based on whether or not the fastener 10 exists. That is, all of the damaged fasteners 10 are accommodated in the spare fastener box 20 and
If no gap is formed between 3, 27, it can be seen that the number of damaged fasteners 10 and the number of used spare fasteners 30 are the same. In addition, if there is a damaged fastener 10 that cannot be accommodated in the spare fastener box 20, it can be understood that the joint where the fastener 10 is used is not joined. Therefore, if such a comparison method is employed, it is possible to very easily compare the number of fasteners 10 and 30 and easily grasp whether or not there is an unjoined portion.

As the spare fastener box 20, various fasteners 31 to 3 are used as in the above embodiment.
A spare fastener box may be prepared for each of the types of fasteners 31 to 35, not limited to those capable of storing the same.
