<Problems when manufacturing foundations on site>
(1) There are many processes, such as groundwork, formwork, concrete placement, and curing.
(2) Since the position of the column base varies depending on the manufacturer of the water heater, the anchor must be positioned each time.

<Problems when loading foundations manufactured at the factory>
(1) Since delivery, carry-in, and foundation installation contractors are separated (separation of labor), there are many on-site process losses, and costs are increased accordingly.
(2) The work of bringing in the water heater is often performed in a narrow part between the building and the site boundary, and the work is time consuming because of its weight.

  By organizing these problems and the required performance required for the foundation, it is possible to reduce the weight and improve work efficiency, shorten the foundation installation process, and easily fix the water heater body to the foundation ( Corresponding to each manufacturer's water heater).

  Therefore, an object of the present invention is to mount an installation that can improve the efficiency of work by reducing the weight, shorten the foundation installation process, and can easily fix the installation to the foundation. It is intended to provide the technology of an assembly type base.

In order to solve the above-mentioned problems, the present invention employs the following means.
The present invention is a precast concrete assembly type base on which an installation having a plurality of attachment portions is placed on the bottom, and is arranged in a first block arranged in the center and arranged side by side on both sides of the first block. Two blocks and a third block, and connecting means for connecting and connecting the side surfaces of each block, the connecting means includes insert fittings with screw holes embedded in both side surfaces of the first block, and The structure includes a bolt hole penetrating between both side surfaces of the second block and the third block, and a connecting bolt inserted into the bolt hole and screwed into the screw hole of the insert fitting.

  According to the assembly type base of the present invention, the three blocks of the precast concrete made of the first block, the second block, and the third block are integrally connected (fastened) by the connecting means. It is possible to reduce the weight and improve the efficiency of transport work and carry-in work. In addition, each block can be integrally connected by a connecting means including a connecting bolt, so that the foundation setting process at the site can be shortened.

  Furthermore, since the insert metal fittings are embedded on both side surfaces of the first block arranged in the center, both the second block and the third block can be connected to the central first block. Thereby, the work space required for the connection work can be further reduced. For example, if there is a space that can be tightened with a box wrench from both sides, the connecting operation can be performed.

  In the present invention, it is desirable that convex portions are provided on both side surfaces of the first block, and concave portions that are fitted to the convex portions are provided on side surfaces of the second block and the third block. When configured in this way, when the second block is joined to one side surface and the third block is joined to the other side surface of both side surfaces of the first block arranged in the center, the concave portion and the convex portion are connected. The blocks can be aligned with each other simply by fitting them together. Therefore, after that, the blocks can be connected together by simply screwing the connecting bolt.

  Here, it is desirable that an opening is provided in a central portion of the end face of the convex portion, and the opening and the screw hole of the insert fitting are formed coaxially. In this way, when the opening and the screw hole of the insert metal fitting are formed coaxially, by forming a part of the insert metal fitting in the convex portion, the convex portion protruding from the side surface of the first block can be formed by the insert metal fitting itself. Can be reinforced. That is, when the convex portion is made of concrete, the insert metal fitting can also function as a convex reinforcing metal fitting.

  In the present invention, it is desirable that attachment grooves for attaching a plurality of attachment portions of the installation object directly or via attachments are provided on the surface side of the second block and the third block. In that case, it is desirable that the fixture is movable along the attachment groove in a state of being prevented from being detached from the attachment groove. If it does in this way, the fixed operation to the foundation of an installation thing can also be performed easily.

  Here, it is preferable that the mounting groove of the third block is disposed near one side surface of both side surfaces of the third block. In this way, by making the side surface joining the third block to the first block either one of the side surfaces or the other side surface, it is possible to correspond widely to the interval between the plurality of mounting portions of the installation object. Is possible.

Each of the mounting grooves is preferably opened on either the side surface or the end surface of the second block and the third block. Thus, by opening the mounting groove on the side surface or end surface of the block, the mounting tool can be taken in and out through the opening, and workability is improved accordingly.

  Furthermore, when the assembly-type base according to the present invention is viewed from another aspect, the following assembly-type base is obtained. That is, an assembly type base made of precast concrete on which an installation having a plurality of mounting portions is placed on the bottom, and at least three base blocks are connected to each other by connecting the side surfaces of the base blocks. Connecting means, wherein the connecting means includes an insert fitting with a screw hole embedded in one side surface of one of the two base blocks to be connected, and the two base blocks An assembly-type base on which an installation object is placed, including a bolt hole penetrating between both side surfaces of the other base block, and a connecting bolt inserted into the bolt hole and screwed into the screw hole of the insert fitting. .

  About the assembly type base which concerns on this invention, the base block used as the basic composition is not limited to three, What is necessary is just to be formed by at least three. The base blocks are connected to each other by connecting means, as in the case of the assembly type base described above. That is, when one base block and the other base block are connected, the connection bolt is passed through the through bolt hole provided in the other base block and the connection is made to the insert fitting provided in the one base block. Both are connected by screwing the bolts together. And this connection is performed between each base block, and an integral assembly type base is formed. Thereby, in the assembly base which concerns on this invention, while being able to aim at shortening of the foundation installation process in a field, the work space required for a connection operation | work can be made smaller.

  Further, in the assembly type base, mounting grooves for mounting the plurality of mounting portions via mounting tools are provided on the surface side of at least two base blocks of the base blocks, respectively. The mounting grooves may not be formed on the same straight line. Accordingly, the installation work can be easily fixed to the foundation, and the installation groove can be more stably installed because the attachment groove is not formed on the same straight line.

  Furthermore, in the above assembly type base, when four base blocks, which are rectangular parallelepiped blocks, are provided, three of the base blocks are connected to both sides of one base block. And the remaining one base block is connected to each base block by the connecting means in a state of being joined to one surface of the base block in the connected state. May be.

  The assembly-type base according to the first embodiment is a precast concrete structure on which a water heater (installation object) P having a plurality of attachment portions is placed on the bottom, and includes a first block 1 disposed in the center, A connection in which the second block 2 and the third block 3 arranged side by side on both sides (left and right) of the block 1 and the side surfaces of the first block 1, the second block 2, and the third block 3 are joined and connected. Means 5 are provided.

  The connecting means 5 includes insert metal fittings 13 with screw holes 13a embedded in both side surfaces 11 and 12 of the first block 1, and both side surfaces 21, 22, and 31 of the second block 2 and the third block 3, And bolt holes 23 and 33 penetrating between 32 and connecting bolts 51 (see FIG. 3) inserted into the bolt holes 23 and 33 and screwed into the screw holes 13 a of the insert fitting 13.

  Next, these details will be described. Each of the first block 1, the second block 2, and the third block 3 has a substantially rectangular planar shape, and the overall planar shape is substantially in a state where side surfaces corresponding to the long sides of each block are joined. Designed to be square. In this embodiment, each block is formed as a rectangular unit block having a long side of 75 cm, a short side of 25 cm, and a thickness of about 15 cm. Of course, here, an example is shown so that the size of the base can be easily grasped, and it may be formed in a different size depending on the type, size, weight, etc. of the installation object.

  The both side surfaces 11 and 12 of the first block 1 are provided with frustoconical convex portions 14, and the side surfaces of the second block 3 and the third block 3 are provided with concave portions 24 and 34 that fit the convex portions 14.

The shape of each of the recesses 24 and 34 is formed in an inverted truncated cone shape (bowl shape) corresponding to the truncated cone-shaped convex portion 14.

An opening 14 a is provided in the central portion of the end face of each convex portion 14. And the opening 14a and the screw hole 13a of the insert metal fitting 13 are formed so that it may become coaxial. By forming the opening 14a and the screw hole 13a of the insert fitting 13 coaxially, a part of the insert fitting 13 can be embedded in the convex portion. If it does so, the convex part 14 which protruded from the side surface of the 1st block 1 can be reinforced with the insert metal fitting 13 itself.

  On the surface side of the second block 2 and the third block 3, three attachment portions (two shown in FIG. 1) 6 of the water heater P, which is an installation object, are attached via attachments 7 such as bolts and nuts, respectively. A mounting groove 8 is provided. In that case, in order to be able to easily fix the water heater P to the base K, the fixture 7 is movable along the mounting groove 8 in a state of being prevented from being detached from the mounting groove 8. It is configured.

  As shown in FIGS. 7 and 8, the mounting groove 8 is formed by a rail-type embedded metal fitting 81 for the mounting groove. The embedded fitting 81 includes a receiving portion 82 of the head 72 of the bolt 71 constituting the fixture 7, and a flange portion 83 that functions as a retaining portion of the head 72 by narrowing the groove width of the opening of the attachment groove 8.

It becomes possible.

  FIG. 9 shows the installation of the third block 3 with the orientation changed by 180 degrees. In the base KI in this assembled form, the third block 3 is compared with the base K in the assembled form shown in FIG. The mounting grooves 8 and 8 are arranged closer to the first block 1. Therefore, by using these two assembly forms, it is possible to install tank units of almost all manufacturers.

In addition, when the second block 2 is joined to one side surface 11 and the third block 3 is joined to the other side surface 12 of both side surfaces of the first block 1 arranged at the center, the four convex portions are connected. The blocks can be aligned with each other simply by fitting 14 into the corresponding recesses 24 and 34 respectively. That is, the convex portion 14 and the concave portions 24 and 34 exhibit a guide function at the time of alignment. Therefore, the blocks can be connected together by simply screwing the connecting bolt 51 thereafter.

  Here, before connecting the blocks, for example, a urethane-based sealing material may be thinly applied to the surface of each convex portion 14. If it does so, the characteristic and watertightness of a sealing material can be used effectively, the connection bolt 51 can be protected from moisture, and the rust prevention function of the connection bolt 51 can be exhibited for a long time even in an outdoor environment.

It is possible to improve the efficiency of work and carry-in work. In addition, each block is integrally connected by the connecting means 5 including the connecting bolt 51, so that the installation process of the assembly type base K can be shortened.

  Here, since the three blocks are connected by four connecting bolts 51 arranged in the horizontal direction, they are supported by the pulling of the connecting bolt 51 for a horizontal earthquake and connected for a vertical earthquake. The bolt 51 is supported by the shearing force of the bolt 51 and the concave and convex fitting portions between the blocks by the convex portion 14 and the concave portions 24 and 34. Thereby, the base K strong against an earthquake can be obtained.

  Furthermore, since the insert metal fittings 13 are embedded on both side surfaces of the first block 1 disposed in the center, both the second block and the third block are connected to the central first block 1 with a short connecting bolt 51, respectively. It can be set as the structure to connect. Thereby, the work space required for the connection work can be further reduced. For example, if there is a space that can be tightened with a box wrench from both sides, the connecting operation can be performed. In each of the above drawings, reference numerals 15, 25, and 35 indicate empty spaces for putting fingers in order to make it easy to carry blocks and the like.
