Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a masonry tool used for masonry of a hollow concrete block (hereinafter, simply referred to as "block") and a dry masonry method of a block using the same, which shortens the construction period and It was developed for the purpose of improving workability. If the conventional method is a wet method, the method using the masonry tool according to the present invention can be said to be a dry method.

2. Description of the Related Art A conventional masonry method for building blocks is a method of sequentially stacking a basic block B1 and a horizontal streak block B2 shown in FIG. 6, and generally, as shown in a perspective view of FIG. The conventional masonry method will be described below according to the procedure. 1. Fix the vertical rebar a at each vertical joint (joint). 2. While adjusting the level with the floor mortar m, stack the basic block B1 on the first stage. 3. Lay the mortar m on the upper surface of the first-stage basic block B1 and stack the second-stage horizontal streak block B2 on it. 4. Fill mortar m in the vertical joint cavity containing vertical rebar a. 5. The horizontal reinforcing bar c is passed to the upper surface recess B21 of the horizontal reinforcing block B2, the mortar m is filled, and the horizontal reinforcing bar c and the vertical reinforcing bar a are bound by the iron wire. 6. Repeat this operation to stack blocks B to the specified height. In the case of a partition wall, the uppermost part of the vertical reinforcing bar a is fixed to (ceiling, building frame). 7. Joints of each block B are subjected to joint displacement before hardening of mortar m. It is completed when the hardening of the mortar is completed and the strength is obtained.

[0003]

The conventional masonry construction method of the block mentioned above is a wet construction method using mortar, and there is a problem that a certain curing period is required until the mortar hardens. Moreover, with this wet method, almost no strength can be obtained until the hardening of the mortar begins, so the daily stacking height is limited to 1.6 meters (8 steps in blocks). Was required to be completed. Further, in this conventional method, it is necessary to work while interposing the mortar, which is a fluid, in the block stacking, so that the skill of the loader must be relied upon, and the unevenness of the block surface occurs depending on the loader. There was also a problem. It is an object of the present invention to develop a block laying tool that does not require skill and has a suitable stacking height, and to establish a suitable method for using it.

[0004]

In view of the above, according to the present invention, the above-mentioned problems of the conventional block masonry construction method are that strength and stability can be obtained by hardening mortar and adhering rebar therewith. Paying attention to that, the final mortar is used to maintain the airtightness in the vertical and horizontal joints and to make makeup so that there is no discomfort in the appearance, but strength and stability are determined by using the fitting members that can be connected. We propose an apparatus that enables masonry without waiting for the hardening of mortar and a dry masonry method using the same. That is, the block masonry tool according to the present invention connects the longitudinal direction of the block and a vertical joint interval with a base bar capable of anchoring and fixing, which has a connection socket provided corresponding to the block length. Used for this purpose, while fixing a pair of rails centering on an internal connecting body that fits into the side cavity portion formed between the side end portions of adjacent blocks, that is, a pillar connected to the connecting socket, Vertical joints, which are sandwiched between plastic or rubber moldings, horizontal joint backups that intervene to form horizontal joints on the basic block, and the main part fits into the recess formed on the upper end surface of the horizontal block. Consists of a molded body of plastic or rubber that forms a hollow and a horizontal joint, and engages with each rail of the vertical joint joiner at both ends thereof. And it is characterized in that comprising a horizontal joint Joyner formed by projecting the stop member. Further, in the dry masonry construction method according to the present invention, which uses the above-mentioned block masonry equipment, 1. Place the base bar on the installation surface and fix it by anchoring. 2. Screw the vertical joint joiner column into the connecting socket on the base bar. 3. Insert the basic block of the first step between each vertical joint and stack it. 4. Lay the horizontal joint backup on the first basic block and the second horizontal block for vertical streak joiner. 5. Insert the locking body of the horizontal joint joiner into the rail of the adjacent vertical joint joiner and fit it into the recess of the concrete block for horizontal reinforcement, and fix the locking body and the rail. 6. Stack the third basic block on the horizontal joint Joiner 5. 7. Connect the vertical joint joiner 2 with the socket 3. 8. Lay the horizontal joint backup 4 on the third basic block and the fourth horizontal block for horizontal streak so that it fits between the vertical joints. 9. Repeat this series of operations to stack blocks to the specified height. 10. After stacking, fill the joint with mortar. This is a method of performing the masonry of blocks through the steps of.

[0005]

As described above, the block masonry tool of the present invention comprises a base bar, a vertical joint joiner, a horizontal joint backup, and a horizontal joint joiner.
When the block B is assembled, these members are fitted and arranged on both sides and above and below the block B to assemble the blocks B. Therefore, according to the conventional method, the blocks have the same strength as the mortar is hardened. Can be stacked.
Therefore, the skill level of the stacker is not required, and it is possible to stack the mortar at a predetermined height without waiting for the mortar to harden. In that sense, if the conventional masonry method for blocks is a wet method using rebar and mortar, it can be said that the masonry tool according to the present invention and the method using the same are dry methods.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be described below with reference to the embodiments shown in the drawings. Concrete block masonry equipment
The base bar 1, the vertical joint joiner 2, the socket 3, the horizontal joint backup 4, and the horizontal joint joiner 5 are described in order.

The base bar 1 shown in FIG. 2 is one in which concrete is poured in advance and fixed to a flat installation surface, and the first step of the block B is placed on it. A connecting socket 12 having an internal thread cut in accordance with the length is provided upright, and a hole 13 is formed near the connecting socket 12 for driving a fixing anchor (not shown).

The vertical joint joiner 2 corresponds to a conventional vertical reinforcing bar a and a mortar m filled around the conventional vertical reinforcing bar a. As shown in FIG. An internal connector that is used to form a vertical joint space and is fitted into a side cavity portion formed between the side end portions of the blocks B and B adjacent to each other. Specifically, the pair of rails 22, 22 centering on the support column 21
While fixing these, these are hard urethane foam resin 2
It is sandwiched between 3 and 23. The column 21 is formed so as to penetrate vertically and has a thread formed on the outer circumference of the end so that it can be connected to the connection socket 12. It is designed so that it can be connected to Joint Joiner 2. The material to be sandwiched is not limited to rigid foamed urethane, and other molded bodies such as plastic or rubber can be adopted. The molded body may have elasticity capable of absorbing the deformation of the block B and strength capable of withstanding a load, and can be easily cut and scraped as needed. The rail 22 is for slidingly inserting the locking body 52 of the horizontal joint joiner 5 described later. In the illustrated example, the support column 21 is made of a steel pipe, but it may be made of steel bar.

As shown in FIG. 4, the horizontal joint backup 4 is for forming a horizontal joint interval on the basic block B1 and is a basic block B, B stacked in the horizontal direction.
It is composed of a pair of foamed hard urethane resins having a length sufficient to be disposed across the space. The lateral joint backup 4 may be cut to an appropriate length and used. Further, similar to the vertical joint joiner 2, the material of this material is preferably a foamed hard urethane resin, but is not limited to this.

The horizontal joint joiner 5 corresponds to the conventional horizontal reinforcing bar c and mortar m, and is a recess B formed on the upper end surface of one horizontal reinforcing block B2 arranged in every second stage.
21. A semi-cylindrical body 51 made of a rigid foamed urethane resin that fits in the inner wall 21 and constitutes a lateral joint, and locking bodies that engage with the rails 21 of the vertical joint joiner 2 at both ends of the semi-cylindrical body 51 It is configured by projecting 52. In the illustrated example, the locking body 52 is a round bar 52a penetrating the semi-cylindrical body 51.
And a rectangular parallelepiped connecting metal piece 52b conforming to the shape of the rail 21 attached to both ends thereof.

Next, a concrete method of laying concrete blocks using the concrete block laying tool having the above construction will be described below. 1. Place the base bar 1 on the installation surface and fix the base bar 1 by driving the anchor. 2. Connect the vertical joint joiner 2 to the connecting socket 1 of the base bar 1.
Attach it by screwing it in 2. 3. Insert the basic block B1 of the first step between each vertical joint joiner 2 and stack. 4. Lay the horizontal joint backup 4 on the first-stage basic block B1 and the second-stage horizontal block B2 so that it fits into the vertical joint joiner 2. 5. The locking bodies 52, 52 of the horizontal joint joiner 5 are inserted into the rails 21, 21 of the adjacent vertical joint joiners 2, 2 so as to be fitted into the concave portions B21 of the horizontal streak block B2 to form the locking bodies 52, 52. The rails 21, 21 are fixed by welding. 6. Stack the third basic block B1 on the horizontal joint joiner 5. 7. Connect the vertical joint joiner 2 with the socket 3. 8. Lay the horizontal joint backup 4 on the third basic block B1 and the fourth horizontal block B2 between the vertical joint joiners 2. 9. Repeat this series of operations to stack blocks B to the prescribed height. When using a partition wall, the upper end of the vertical joint joiner 2 is fixed to the ceiling. 10. After stacking, fill the joint with mortar.

In the illustrated example, the vertical joint joiner 2 has the length of the block B corresponding to three stages, but the length is not limited to this, and the length of the block B can be plural stages. The connecting means of the vertical joint joiner 2 is the male screw formed on the outer circumference of the column 21 of the vertical joint joiner 2, the connecting socket 12 and the socket 3, but the connecting means is not limited to this. In addition, although the vertical joint joiner 2 and the horizontal joint joiner 5 are shown as being configured to be integrated by welding, they are not necessarily limited to this, and may be integrated assuredly.

The final step of filling the joint with mortar is
It suffices to use a small amount between the blocks B and B which are stacked through the vertical joint joiner 2, the horizontal joint joiner 5, and the horizontal joint backup 4. This joint filling has the meaning of maintaining airtightness and makeup. In addition, horizontal joint backup 4
Is a temporary joint space because it secures a lateral joint space and prevents mortar from flowing into the cavity of the block B at the time of joint filling so as not to impair the workability and is simply placed on the basic block B1. Although it can be said that it is fixed, it is fixed by the solidification of the mortar by the joint filling with the mortar and the stability is increased.

[0014]

According to the present invention having the above-described structure and construction method, the joint spacing formed around the block B is a vertical joint joiner, a lateral joint backup, or a horizontal joint joiner having strength and rigidity. Since it is constructed, it is not based on mortar having fluidity as in the past, so there is no restriction on the stacking height once. In addition, according to the present invention, since the vertical joint joiner and the horizontal joint backup are fitted in the concave portion of the block B, the block B
Therefore, the stacking position of the block B is regulated, and thus, the finish is largely different depending on the skill level of the stacker, and the block B is not bent or uneven.
