Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a block laying base that is laid under a support block when a support block used to support equipment and piping is installed.
[0002]
[Prior art]
For example, when a concrete block used as a support block is installed on the rooftop, a rubber base is installed, and the block is placed on this base to protect the installation surface and prevent the block from moving is doing. As this type of base, for example, the bases described in Patent Documents 1 to 3 are known.
[0003]
The base described in Patent Document 1 is one in which a suction cup type rubber mat is fixed to the bottom surface of a concrete block by fitting or bonding.
[0004]
Patent Document 2 describes a mat on which a soft member for preventing damage to the floor surface such as a rubber-based material is attached along the longitudinal direction of the bottom surface of the concrete block.
[0005]
Furthermore, the anti-vibration rubber described in Patent Document 3 eliminates the use of this kind of mat, and the anti-vibration rubber is formed in a U-shape at the bottom of a resin mount used in place of a concrete block. Are mechanically locked and attached symmetrically.

[Problems to be solved by the invention]
The mat of Patent Document 1 uses a fitting means or an adhesive means as means for fixing the suction cup type rubber mat to the bottom surface of the concrete block. The fitting means is for fitting the bottom portion of the concrete block into the concave portion formed in a shallow basin shape. For this reason, it is necessary to provide the mat in a shape that always fits the bottom of the concrete block, and there is a disadvantage that a sucker type rubber mat having a different shape and size must be formed for each shape and size of the concrete block. .
[0008]
In addition, according to the description of Patent Document 1, a sucker type rubber mat is formed by a concave portion provided in the central portion of the mat and a contact portion provided around the concave portion, and the load of the concrete block and the deformation of the mat are utilized. The mat is used as a suction disk. Then, as for the mat pressed with the load of the concrete block, the circumference | surroundings of a mat will spread as a whole as if the suction cup was affixed. As a result, the shallow basin portion fitted around the bottom of the concrete block is separated from the concrete block. Therefore, even if the suction force to the floor surface can be increased with the sucker of the mat, the engaging force with the concrete block placed on the mat has to be extremely weak.
[0009]
On the other hand, the mat described in Patent Document 2 is a mat for affixing a soft member for preventing floor damage such as rubber-based material along the longitudinal direction of the bottom surface of the concrete block. It will take time. In addition, if the attached mat is removed even once, the adhesive strength is extremely reduced, and there is a disadvantage that the mat is detached from the bottom surface in a place where the vibration is intense.
[0010]
Further, the anti-vibration rubber described in Patent Document 3 is used in place of this kind of mat, and mechanical vibration anti-vibration rubber formed in a U shape is formed at the bottom of a resin mount used as a support block. Is locked. That is, a large number of pins project from the lower part of the resin mount and are mechanically locked by inserting the pins into pin holes opened in the upper surface of the vibration-proof rubber. Therefore, even if this anti-vibration rubber is suitable when using a resin mount capable of forming a large number of pins, it cannot be used when using a concrete block where it is difficult to form pins.
[0011]
Therefore, the present invention has been created to solve the above-described problems, and can be securely fixed to the support block, can be removed by many vibrations, and can be attached to and detached from the support block. The object is to provide a block laying base that is easy to work and can be used over and over again.
[0012]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the first means of the present invention is to form an elastic band-like substrate 1 on a block laying base to be laid on the lower surface of the support block P, and block P from both longitudinal ends of the substrate 1. A pair of locking protrusions 2 that are inclined to the side are provided, and a lower surface protrusion 3 that protrudes downward from the substrate 1 by extending the lower end portion of the locking protrusion 2 in the inclined direction is placed on the substrate 1. The lower surface protrusion 3 deformed by the load of the block P is to press the locking protrusion 2 against the side surface of the block P.
[0013]
The substrate 1 in the second means is made of a synthetic rubber material of ethylene propylene rubber, chloroprene rubber, or neoprene rubber, and is formed to have a length arranged along the short direction of the support block P. A means for solving the problem.
[0014]
According to the means of the present invention, the load of the block P pushes and spreads the lower surface protrusion 3 so that the tip of the locking protrusion 2 continuous with the lower surface protrusion 3 is pressed against the side surface of the block P.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The base of the present invention is laid on the lower surface of a support block P such as a concrete block used for supporting equipment and piping. The base of the present invention is formed of an elastic material, and for example, a synthetic rubber material such as ethylene propylene rubber, chloroprene rubber or neoprene rubber is preferable. In addition, a material having elasticity and excellent durability, water resistance, and weather resistance can be appropriately selected.
[0016]
The belt-like substrate 1 is formed from the elastic material as described above. This board | substrate 1 is formed in the length distribute | arranged along the transversal direction of the block P for support (refer FIG. 1). That is, the block P having an arbitrary length is used depending on the place of use, but the length of the block P itself does not change much. Therefore, by forming the width of the block P, that is, the length arranged along the short direction, the block P is formed so as to correspond to the block P whose length is changed. Although two substrates 1 shown in FIG. 1 are used, any number may be used depending on the length of the block P.
[0017]
Reference numeral 2 denotes a pair of locking projections that incline toward the block P from both longitudinal ends of the substrate 1 (see FIG. 2). Since the locking projections 2 are inclined inward from both ends of the substrate 1, when the substrate 1 is mounted on the bottom of the block P, the locking projections 2 are expanded and mounted (see FIG. 3). Since the locking projection 2 is formed integrally with the substrate 1 and has the same elasticity as the substrate 1, the locking projection 2 is crimped and locked so as to sandwich the side surface of the block P by the elastic force of the locking projection 2. . At this time, the latching protrusion 2 and the substrate 1 can use a synthetic resin material in addition to the synthetic rubber material. Further, since the latching protrusion 2 is locked to the bottom of the block P by the elastic force, even if the length of the mounting surface of the substrate 1 is slightly longer than the length of the bottom width of the block P, the locking protrusion 2 Can be securely locked. As a result, the size of the applicable block P increases, and the type of support block can be mounted on a light synthetic resin block or the like in addition to a concrete block.
[0018]
A pair of locking projections 2 that incline toward the block P from both longitudinal ends of the substrate 1 are provided, and a lower surface projection 3 that protrudes downward from the substrate 1 by extending the lower end of the locking projection 2 in the inclined direction. This is provided (see FIG. 2). Since the lower surface protrusion 3 protrudes below the substrate 1, it is formed so that both ends of the substrate 1 are deformed by the load of the block P.
[0019]
That is, when the substrate 1 is mounted on the lower surface of the block P, the locking projection 2 is opened as described above and mounted on the block P (see FIG. 3). Next, when the block P is placed at a predetermined position in this state, the lower surface protrusion 3 is deformed by the load of the block P, and the lower surface protrusion 3 is pushed outward (see FIG. 4). Then, the locking protrusion 2 extended obliquely above the lower surface protrusion 3 is pressed in the direction opposite to the lower surface protrusion 3, that is, in the direction of the block P. As a result, the locking protrusion 2 pushes the side surface of the block P. It will be locked with a strong pressing force. Thus, since the locking protrusion 2 presses the block P due to the deformation of both ends of the substrate 1 by the lower surface protrusion 3, the material used in this embodiment is ethylene propylene rubber, chloroprene rubber, neoprene rubber or the like. A synthetic rubber material is preferred.
[0020]
The lower surface protrusion 3 in the illustrated example is formed in a state inclined obliquely outward from the lower surface of the substrate 1 in order to easily spread outward (see FIGS. 1 and 2). And in order to raise the pressing force of the latching protrusion 2, the connection part of the lower surface projection part 3 and the latching protrusion 2 is thickened, and the reinforcement | strengthening part 3A is formed (refer FIG. 4). On the other hand, the locking protrusion 2 is formed so as to become thinner toward the top end in order to improve the adhesion with the side surface of the block P.
[0021]
【The invention's effect】
The present invention achieves the original object by being configured as described above.
[0022]
That is, the elastic band-shaped substrate 1 is formed, and the pair of locking projections 2 that are inclined from the both longitudinal ends of the substrate 1 toward the block P are provided, so that the fixing to the block P can be performed reliably. Moreover, there is no risk of disengagement due to many vibrations. Moreover, the attachment / detachment work to the block P is easy, and it can be used repeatedly any number of times. In addition, the size of the applicable block P is widened and the versatility is enhanced. In addition, a lower surface protrusion 3 is provided which extends in a slanting direction at the lower end of the locking protrusion 2 and protrudes downward from the substrate 1, and the lower surface protrusion 3 deformed by the load of the block P placed on the substrate 1. By pressing the locking projection 2 against the side surface of the block P, in addition to the above effects, the locking projection 2 can be pressed and locked using the load of the block P. Furthermore, since the deformed lower surface protrusion 3 strongly presses the floor surface, the bonding force between the substrate 1 and the floor surface also increases in proportion to the load of the block P. As a result, as the block P becomes heavier, a more reliable locking force and bonding force can be obtained, and an effect completely different from the conventional base in which the locking force becomes fragile by placing the block is achieved. Is.
[0023]
As described above, according to the present invention, the fixing to the block P can be surely performed, and there is no possibility of being detached by a lot of vibrations, and the attaching / detaching operation to the block P is easy, and it can be used repeatedly. It is possible to achieve various beneficial effects such as being possible.
