Abstract

PURPOSE:To enhance the earthquake-proof ability by supporting the lower part of a coupling spacer piercing through a joint plate, to a receiving stage of a lower block, by fitting the upper part of the spacer into a fitting pipe in an upper block, and by passing reinforcement in a through-hole in the spacer and the fitting pipe. CONSTITUTION:A coupling spacer 3 is inserted in a joint plate 5 so as to form an interposing panel 11, and the lower and lower parts of the spacer 3 are inserted in a receiving stage 10 of a lower block 12 and a fitting tube 8 in an upper block 14 so as to support the lower block 13 and the upper block 14 stacked one upon another. Then reinforcement bar 16 is inserted through a vertical hole 7 and a through hole 2. The spacer 3 and plates 3, 5 are made of materials such plastic materials having a viscoelasticity, a friction force and a resilient force which are large. Further, the entire structure can have a vibration system of a multi-degree freedom so as to prevent the structure from resonating with high frequency oscillation of an earthquake. Since the plate 5 has a large viscoelasticity, a large vibration suppressing force for high frequency oscillation is generated. Further, due to the combination of the concrete and the soft plastic material or the like, a large friction force can be induced therebetween. Thereby it is possible to enhance the earth-quake ability. Accordingly, it is possible to enhance the earth-quake ability and to facilitate the construction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block wall having earthquake resistance.

[0002]

2. Description of the Related Art The prior art has the following drawbacks because it has a structure in which blocks are adhered with mortar or the like.

Since the structure has a rigid structure integrated with mortar and the like, the structure has a high natural frequency and resonates with the seismic frequency, so that the structure is easily broken and the earthquake resistance is poor.

There is little viscoelastic loss in the structure, little damping against vibration, and poor seismic resistance.

Since there is no frictional force due to the mutual movement between the internal structures, the damping is small and the earthquake resistance is poor.

Since an adhesive material such as mortar is used, it is difficult for an amateur to carry out the construction.

When a reinforcing bar is used together, it is necessary to lift the block high, which makes the work difficult.

[Problems to be Solved by the Invention]

By lowering the natural frequency of the structure, increasing the viscoelastic loss, and imparting frictional force, the seismic resistance is improved, and the adhesive such as mortar is omitted to facilitate the construction by an amateur. This is the realization of a seismic block wall construction method with high work efficiency.

It has a joint plate with joint holes through which the connecting spacers pass, and the vertical hole that is passed through the block in the vertical direction has a fitting diameter at the lower end that is the size of the connecting diameter. It is a receiving step that has been expanded to the size of the connecting plate.The connecting plate is passed through the joint plate to form an interposing plate, and the lower part of the connecting plate is supported by the receiving plate of the lower block, and the connecting plate of the upper block is fitted with the connecting plate of the connecting plate. The upper parts are fitted and stacked, and the reinforcing bars are passed through the vertical holes and the through holes.

EXAMPLES Examples will be described with reference to the drawings.

The circumscribing circumference 1 has a cylindrical shape with a connecting diameter, and is provided with a connecting spacer 3 having a through hole 2 along its center. Although the connecting spacer 3 has four protrusions, it is not limited to this.

A joint plate 5 having joint holes 4 through which the connecting spacers 3 pass is provided.

A vertical hole 7 which is vertically passed through the block 6.
Is a receiving stage 10 in which the fitting cylinder 8 at the lower end has the size of the connecting diameter, and the upper end of the conical hole 9 which extends narrowly upward is expanded stepwise to the size of the connecting diameter.

The connecting plate 3 is inserted through the joint plate 5 and the interposing plate 11
And

The lower portion 13 of the connecting spacer 3 is supported by the receiving stage 10 of the lower block 12, and the upper portion 15 of the connecting spacer 3 is fitted and stacked on the fitting cylinder 8 of the upper block 14.

That is, the lower block 12 and the upper block 14 are stacked via the interposing plate 11,
Can be assembled.

The construction is completed by passing the reinforcing bar 16 through the vertical hole 7 and the through hole 2. The reinforcing bar 16 may be a deformed reinforcing bar.

The block 6 can be provided with a suitable lightening 17.

By making one end of the block 6 a convex 18 and the other end a concave 19 and combining them as shown in FIG. 8, it is possible to correspond to a curved wall.

The connecting spacer 3 and the joint plate 5 are preferably made of a material having large viscoelasticity, frictional force, and elasticity, for example, a rubber type or plastic type material can be used. In particular, these wastes can be used and are useful for resource recycling and environmental conservation.

Since the reinforcing bar 16 can be formed by the post-processing method, it is not necessary to lift the block 6 high and the work is easy.

Even if a short reinforcing bar is hit during the construction, there is almost no difference in strength.

Stacking like a conventional block can be performed, and also hanging like a brick can be done. At this time, make half a block.

Since a soft object having a small spring constant is sandwiched between the blocks, the whole structure is a multi-degree-of-freedom vibrating body having a small natural frequency, and its frequency is significantly different from the high frequency vibration of the earthquake. Does not resonate.

Since the joint plate is a soft plastic or the like and has large viscoelasticity, a large damping force is generated during high-speed motion of high frequency vibration. Therefore, even if the vibration is close to the resonance point, many shock absorbers are used. As it has, it does not resonate.

Since it is a combination of concrete and soft plastic or the like, a particularly large frictional force is exerted between them to exert a vibration damping action.

The structure according to the present invention is a multi-degree-of-freedom vibrating body, and a part thereof resonates to act as a vibration absorber so that the whole does not vibrate. It has an ideal vibration absorbing structure because it has a greater damping force.

The present invention can be constructed as a brick-laying bridge construction, and can be connected to the left and right and top and bottom by an intervening plate and a reinforcing bar to form an integral structure, but it has a large resistance to static external force and vertical vibration. is there.

[0029]

Since the present invention is constructed as described above, the following effects are produced.

Since the natural frequency is small and it does not resonate with the frequency of the earthquake, it is seismic resistant.

Since the viscoelasticity of the joint board produces a damping force to damp the vibration, it is aseismic.

Due to the damping effect of the frictional force between the constituent parts,
It is earthquake resistant.

Since the structure constitutes a multi-degree-of-freedom vibrating body, it is an ideal vibration absorbing structure.

Since no mortar or the like is used, construction is easy even for an amateur.

There is no need to lift heavy blocks due to the rebar incorporation.

Both stacking and stacking are possible.

It is easy to construct a curved surface.

Construction and work are easy.

Since waste plastic, waste rubber, etc. can be used, it is useful for resource recycling and environmental conservation.
