Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large steel connecting structure used for constructing a lower part of a building such as a house.

[0002]

2. Description of the Related Art In a building such as a house, a floor structure in which a floor panel is provided over a concrete foundation is employed. For example, as shown in FIG. 1, a concrete foundation 1 is erected from the ground GL on which concrete or the like is cast, and a floor panel 2 is inserted between the adjacent concrete foundations 1 and 1. The floor panel 2 is composed of a large scale 4 supported by a bundle 3
Is fixed with a fixing metal such as a nail or a screw. As the large-scale pulling 4, steel large-scale pulling has begun to be used in place of conventionally used wood. Steel pulling eliminates the drawbacks of wooden pulling, in which deformation such as warping and twisting due to drying shrinkage is likely to occur, and is excellent in dimensional stability.

In order to facilitate the attachment of the steel puller to the bundle, Japanese Patent Application Laid-Open No. 9-217452 discloses an engaging recess provided on the side surface of the steel puller, and an engaging piece caught by the engaging recess. Bundles with are introduced. In this bundle, a receiving bracket 3d is fixed to a support bolt 3b rising from the installation plate 3a via a turnbuckle 3c (FIG. 2A). The receiving bracket 3d is provided with upright pieces 3f on both sides with an accommodation space 3e in which the steel puller 6 can be inserted.
A part of f is cut into a locking piece 3g protruding toward the accommodation space 3e. Engagement projections 6a that engage with the locking pieces 3g protrude from both lower sides of the steel puller 6 connected to the bundle 3. When the steel puller 6 is connected to the bundle 3, the steel puller 6 is inserted from above into the accommodation space 3 e of the bundle 3.
(FIG. 2b), the upright piece 3f is elastically deformed and opens to both sides, and the upright piece 3f is elastically restored when the engaging projection 6a passes over the locking piece 3g. As a result, the locking piece 3g and the engaging projection 6a are engaged with each other, and the steel puller 6 is connected to the bundle 3.

[0004]

However, in the engagement by the method shown in FIG. 2, the elastic deformation of the locking piece 3g protruding from the standing piece 3f to the accommodation space 3e is used only for the engagement force. It becomes a joint structure with weak connection strength. Further, when the standing piece 3f is opened outward, the bottom 3h of the housing space 3e is deformed upward, so that the elastic restoring force effective for the connection strength is further reduced. Further, a restraining force against the steel puller 6 being displaced in the longitudinal direction in the accommodation space 3e cannot be expected much.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem, and employs a structure in which a steel puller and a bundle are firmly connected by a one-touch method. By doing so, it aims at constructing a firm floor structure with good workability. In order to achieve the object, the present invention has a structure for connecting a steel puller on which a joist is mounted, and is fixed to an upper end of a support bolt rising from the ground, and a seat on which the steel puller is mounted. A large receiving plate having a portion on the upper surface and a spring portion fixed to the large receiving plate or formed by bending both sides of the large receiving plate, wherein the spring portion has an effective width greater than the mounting portion fixed to the seating portion. Same as the guide side of the spring part, and the bundled hardware with the locking side and guide side bent at an acute angle via the narrow elastic deformation part formed on the upper part, the seating side placed on the seating part of the large receiving plate. The guided side that rises from one side of the seating side at an inclination angle, and bends from the guided side,
A steel puller having an engagement side in surface contact with the locking side of the spring portion, a side wall extending upward from the other side or the engagement side of the seating side, and having a substantially rectangular hollow cross section is provided. The engaging side of the spring portion and the engaging side of the steel puller mesh with each other in a surface contact state.

[0006] A steel puller in the form of a bottom with an opening extending in the longitudinal direction can also be used. For a steel pulling machine having an opening, it is preferable to use a bundled metal provided with a restraining projection fitted on the opening on the large receiving plate, but a bundled metal without the restraining projection can also be used. Notches can be formed in the rising portions on both sides of the constraining projection, into which large steel ribs facing the opening from both sides are fitted. A large elastic deformation such that the guided side of the steel pulley is slack against a load from above is caused by the contact with the steel pulley and the spring part spreads, and the steel This can be prevented by raising the contacting support side from both sides of the seating portion at the same inclination angle as the guided side. Also, a plate-like support arm extending vertically upward from the center of both sides of the seating portion is provided, and an upper portion of the plate-like support arm is bent, and a support side which comes into contact with an upper surface and a side wall side of the steel puller from inside, respectively. When using the bundled metal having the abutting surface, deformation of the large steel corner is prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 3 (a), for example, as shown in FIG. 3 (a), a large receiving plate 12 is fixed to the upper end of a support bolt 11 by welding or the like. The pull 20 is supported. As the support bolt 11, a bolt provided with a height adjusting mechanism such as a turnbuckle is used as in the related art. Both sides of the large receiving plate 12 are bent portions 12a and 12b bent downward. Bend 1
2a, 12b, the seating portion 1 of the steel puller 20 is inside.
2c. A plurality of reinforcing beads 12d extending from one bent portion 12a to the other bent portion 12b may be formed on the seating portion 12c. Bent parts 12a and 12b and seat part 12c
(FIG. 3b) is set to an obtuse angle.
A leaf spring 13 is fixed to the side surfaces of the bent portions 12a and 12b with rivets 14 or the like. Since the angle α between the bent portions 12a, 12b and the seat portion 12c is obtuse, the leaf spring 13 is fixed to the bent portions 12a, 12b in a state of being narrowed upward as shown in FIG. Is done. Instead of the leaf spring 13, a spring portion formed by bending at both ends of the large receiving plate 12 can be used.

The leaf spring 13 has an elastically deforming portion 13b extending upward from a mounting portion 13a fixed to the bending portions 12a and 12b, and a locking portion 13c is formed above the elastically deforming portion 13b. The mounting portion 13a and the locking portion 13c are bent portions 1
The width of the elastic deformation portion 13b is substantially the same as that of the elastic deformation portions 13a and 12b. Thereby, when a force for expanding the leaf spring 13 is applied, the leaf spring 13 is
Are elastically deformed laterally starting from the mounting portion 13a. The locking portion 13c has a locking side 13d bent from the elastically deforming portion 13b, and an upper portion of the locking side 13d is a guide side 13e bent in the opposite direction. The angle β between the elastic deformation portion 13b and the locking side 13d is set to be less than α in order to incline the locking side 13d downward toward the center of the seating portion 12c. The angle γ between the locking side 13d and the guide side 13e is set to an acute angle so that the guide side 13e becomes wider.

The steel puller 20 is a substantially rectangular hollow cylinder made by forming a steel plate into a predetermined shape and welding or caulking. The bottom surface of the steel puller 20 is seated on the seating side 2 placed on the seating portion 12c of the large support plate 12.
Becomes 1. Both sides of the seating side 21, that is, corners of the hollow cylindrical body are guided sides 22 formed obliquely. The height of the guided side 22 is set substantially equal to the height from the seat portion 12c to the locking side 13d. The angle between the seating side 21 and the guided side 22 is determined by the seating portion 12c and the guide side 13e.
Is preferably smaller than the angle between (α−β + γ). Thus, the steel puller 20 is connected to the pair of leaf springs 1.
When the guide side 13 is pushed between the guide sides 13 and 13, the guided side 22 is guided by the guide side 13e and moves downward while pushing and expanding the leaf springs 13 and 13.

The upper side of the guided side 22 is an engagement side 23 bent toward the center of the hollow cylindrical body. The engagement side 23 is
In order to bring the locking side 13d in the locking state into surface contact, the locking side is inclined at an angle equal to the angle (α-β) between the seating portion 12c and the locking side 13d. A side wall 24 extends upward from an inner end of the engagement side 23. Side wall 24 and seating side 21
Is set to a right angle. An overhang portion 25 is provided on the upper side of the side wall 24 as necessary, and the upper surface of the hollow cylindrical body is an upper side 26 for placing a joist (not shown).
When the steel puller 20 is pushed from above between the leaf springs 13 as indicated by arrows in FIG.
The seating side 2 while pushing and expanding the guide sides 13e, 13e at 22
1 falls. When the seating side 21 reaches the seating portion 12c, the leading ends of the locking portions 13c, 13c are moved to the guided sides 22, 2, respectively.
Get over 2 As a result, the leaf springs 13 and 13 elastically restore in the direction in which they are narrowed to each other, and as shown in FIG. As a result, the steel puller 20 is firmly connected to the bundle 10. As a connection procedure, the bundled metal 10 set up on the ground GL is connected.
Although it is possible to fit a steel puller 20 into the steel puller 20, a method of fitting a bundle 10 having a height adjusting function such as a turnbuckle into the steel puller 20 in advance and standing upright on the ground GL is a workability. Is excellent. The contact state between the bundled metal 10 and the steel puller 20 is determined by contacting one or both of the contact surfaces thereof, namely, the cushioning material 12k (at the seating portion 12c, the locking side 13d, the seating side 21, the engaging piece 23, etc. FIG. 7) is affixed or previously coated with a resin-coated steel plate and a metal bundle 10 and / or a steel puller 20.
It is further improved by making. The attachment of the cushioning material is also effective in preventing metallic contact noise.

The force for locking the steel puller 20 is determined by the leaf spring 1
Due to the resilience of 3. The elasticity of the leaf spring 13 is
This is generated by the force of the elastic deformation portion 13b elastically deforming from the 3a side, and is much larger than the elastic deformation of the locking piece 3g described with reference to FIG. Moreover, since the locking portion 13c is longer than the elastic deformation portion 13b, the elastic deformation concentrates on the elastic deformation portion 13b,
The elastic deformation of c is suppressed. As a result, the locking side 1
The 3d, 13d and the engaging sides 23, 23 are inclined downwardly toward the center of the seating portion 12c and firmly mesh with each other, so that the steel puller 20 connected to the bundle 10 is not pulled out upward. Also, displacement in the longitudinal direction is prevented. When the steel puller 20 is to be removed from the bundled metal piece 10, the guide side 13e protruding laterally from the steel puller 20 is pushed to the side so that the engagement side 13d engages with the engagement side 23. By releasing the lock, the steel puller 20 is separated from the bundle 10.

As the steel puller 20, instead of a hollow cylinder, a puller having a partially open lower part can be used. For example, as shown in FIG. 4A, a steel puller 20 having an opening 27 extending in the longitudinal direction on the bottom side can be used. Since the steel puller 20 having the opening 27 can be manufactured by forming a steel plate into a predetermined cross-sectional shape, it is more advantageous in manufacturing than a hollow cylindrical body requiring welding. Further, by forming the reinforcing ribs 28 at the edges of the opening 27, the strength around the opening 27 is also ensured. The steel puller 20 provided with the opening 27 is also connected to the bundle 10 shown in FIG. 3 by the same operation. However, when the seating side 21 of the steel puller 20 is fitted between the leaf springs 13, 13, the seating side 21 divided right and left by the opening 27.
R, 21L are locking portions 13c, 13c of the leaf springs 13, 13
To be displaced inward, and the engagement between the locking side 13d and the engaging side 23 may be weakened.

The inward displacement of the seating sides 21R, 21L can be suppressed by providing the restraining protrusions 12e, 12e on the large receiving plate 12 of the bundle 10. The restricting projection 12 e is cut and raised from a side of the large receiving plate 12 and has a width that fits into the opening 27. FIG.
As shown in (b), it is set higher than the locking portion 13c of the leaf spring 13 fixed to the bent portions 12a, 12b. It is preferable that the upper end of the restraining projection 12e be narrow in order to facilitate insertion into the opening 27. Restraint protrusion 1
When the steel puller 20 is connected to the bundled metal piece 10 having 2e, when the steel puller 20 is lowered as shown by the arrow in FIG. 4A, the upper end of the restraining projection 12e enters the opening 27. Later, the guided side 22 comes into contact with the guide side 13e of the leaf spring 13. Therefore, the left and right seating sides 21R, 21L are supported from the inside by the restraining projections 12e, and the inside displacement of the seating sides 21R, 21L due to the pressing of the locking portion 13c is suppressed. As a result, as shown in FIG. 4 (c), the locking side 13d and the engaging side 23 engage with each other with the restraining projection 12e fitted into the inside of the steel puller 20, and the steel puller is attached to the bundle 10. 20 is firmly connected.

It is also possible to incorporate a mechanism for locking the rib 28 with the restraining projection 12e. In this case, for example, FIG.
As shown in (a), notches 12f substantially equal to the height of the rib 28 are formed on both sides of the rising portion of the restraining projection 12e.
When the steel puller 20 is pushed down in the direction of the arrow, the restraining projection 1
The seating sides 21R and 21L descend between the both sides of the restraining projection 12e and the leaf spring 13 while the opening 27 extends along the inclined surface 2e. When the rib 28 reaches the notch 12f, the opening 27 is narrowed by the elastic restoring force of the steel puller 20, and as shown in FIG.
8 meshes. This engagement prevents the steel puller 20 from coming off, as well as the reinforcing rib 28, the seating side 21, and the guided side 2
2 is also prevented. FIG. 5 (c) is a view of the steel puller 20 attached to the bundled metal piece 10 as viewed from the side.

When the steel puller 20 is pushed down toward the bundle 10 having the supporting side 12g, the guide side 13e of the leaf spring 13 comes into contact with the guided side 22 and the leaf spring 13 is elastically deformed in the opening direction. . When the steel puller 20 is further pushed down, the guided side 22 comes into contact with the supporting side 12g. From this point, the openings 2 are formed by the rigid supporting sides 12g, 12g.
7 is applied to the seating sides 21R and 21L. Moreover, the seating side 21 is formed by the supporting sides 12g and 12g.
R, 21L are pressed against the restraining projection 12e, and the notch 1
The engagement between the ribs 2f and the ribs 28 is strengthened, and the connected steel puller 20 is prevented from being deformed.

When a large downward force is applied to the steel puller 20 after the steel puller 20 is connected to the bundle 10, the opening 27 of the steel puller 20 may be widened. Opening 27
In order to prevent the spread, the support sides 12g, 12g are raised obliquely upward from the central portions on both sides of the seat portion 12c.
The support side 12g rises from the seating portion 12c at substantially the same inclination angle as the guided side 22 of the steel puller 20, and the leaf spring 1
3 facing the opening 13f. Opening 13f
Has the effect of narrowing the effective width of the leaf spring 13 and concentrating the elastic deformation of the leaf spring 13 on the elastic deformation portion 13b.

An upper side 26 of the steel puller 20 is attached to the bundle 10.
Can also be provided with a function to support from below. In this case, as shown in FIG. 6, for example, the seat portion 12c has an elongated shape, and the plate-like support arms 12h, 12h extend vertically upward from the middle recesses on both sides of the seat portion 12c.
The upper surface of the support surface 12i, 12h is bent horizontally.
i. However, the seating portion 12c in FIG. 6 does not directly contact the steel puller 20 unlike the seating portion 12c in FIG. 3, and supports the steel puller 20 from the inside by the support surface 12i. The tip of the support surface 12i is bent further downward, and the contact portion 12 that comes into contact with the side wall 24 of the steel puller 20 from the inside.
j, 12j. The contact surface 12j also functions as a reinforcing rib of the plate-like support arm 12h. An appropriate cushioning material 12k may be attached to the support surface 12i to improve the contact state with the steel puller 20, and to absorb vibration and prevent metal noise. The leaf springs 13 are fixed to the bundle 10 at both sides of the support side 12g. Each leaf spring 13 is formed by molding one leaf spring into a shape surrounding the seat portion 12c. The upper end of the vertical portion 12g that rises from the edge of the seating portion 12c is a locking portion 13c that is bent at an acute angle, and the locking portion 13c is further bent at an acute angle to form a guide side 13e.

Steel puller 20 connected to bundle 10
Are sequentially bent inward on both sides of the steel plate to form seating sides 21R, 21L, guided sides 22, 22, and engaging side 2
3, 23 are formed. An opening 27 into which the plate-like support arm 12h is inserted is formed between the seating sides 21R and 21L. Since the steel puller 20 formed by bending both sides inward in this manner has no overhangs or protrusions on the sides, it can be easily transported and handled at a construction site. In the example of FIG.
The plate-like support arm 12h and the support surface 12i of the bundle 10 are fitted into the inside of the steel puller 20 from the end opening of the steel puller 20, and the bundle 10 is slid in the longitudinal direction of the steel puller 20. Then, it moves to a predetermined position of the steel puller 20.
At this stage, the contact surface 12j contacts the inner surface of the side wall 24 (FIG. 6B).

After the bundled metal piece 10 is positioned at a predetermined position of the steel puller 20, when the steel puller 20 is pushed down, the guided side 22 contacts the guide side 13e and the seating side 21
R and 21L are expanded. Guided side 22 is guide side 1
3e, the opening 27 is narrowed by the elastic restoring force, and the engaging side 23 is engaged with the locking portion 13c (FIG. 6).
c). At this time, the support side 1 is
2i contacts from inside. That is, since the corner of the steel pulley 20 that is easily deformed by contact with foreign matter is supported from the inside by the support side 12i and the contact surface 12j, the deformation of the steel pulley 20 is prevented. Further, when the cushioning material 12k is interposed between the support side 12i and the upper side 26, the force and vibration applied to the steel pulling 20 from above are absorbed by the buffering material 12k. Prevention becomes more effective.

As described above, the floor panel is arranged on the steel pulley 20 firmly connected to the bundle 10, so that a firm floor structure is constructed. In addition, since the steel pulley 20 can be passed over the ground GL by mounting the bundle 10 mounted on the steel pulley 20, the workability is greatly improved.

[0021]

As described above, the connecting structure of the present invention employs a method in which the engaging side formed on the spring portion of the bundled metal piece and the engaging side of the large steel puller are engaged in surface contact. As a result, the steel puller is firmly connected to the bundled metal, and a connection structure that is resistant to the pulling force in the vertical direction and the displacement along the longitudinal direction is obtained. In addition, since the steel puller is connected only by inserting the steel puller from above into the space between the pair of leaf springs, workability is remarkably improved. When floor joists are laid with the joists on the steel puller attached in this way, a solid floor structure is easily constructed.
