Abstract

PURPOSE:To construct a wall formed of a ground mesh plate buried in the center of a sprayed mortar or concrete layer in a short period of time and very economically by simple work without requiring so much man-power. CONSTITUTION:A ground mesh plate (a) formed of a lath 3 having both sides with which wire nets 1 and 2 are brought into contact is erected and installed at an opening section 4 of a structure. A mortar or concrete layer (b) having the ground mesh plate (a) buried in the center thereof is formed by spraying the mortar or the concrete to both sides of the ground mesh plate (a) one side by one side or both sides at a time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall construction method by spraying and its wall.

[0002]

2. Description of the Related Art Walls of various concrete structures, for example,
The outer walls and partition walls are usually constructed of cast-in-place concrete or precast concrete boards.

[0003]

When the cast-in-place concrete method is used, there are incidental works such as assembling and dismantling of the formwork, requiring skilled workers for that purpose, and lengthening the construction period, which increases the cost. There are drawbacks such as

[0004] When using the precast concrete board, there are drawbacks such that it must be manufactured at a factory, the heavy precast concrete board must be transported to the site, and it must be mounted at a predetermined position by using a heavy machine. . The present invention has been proposed for the purpose of eliminating the drawbacks of these conventional methods by adopting the spraying method.

[0005]

The wall construction method by spraying according to the present invention includes the following steps. Wire meshes 1 and 2 are contact-polymerized on both sides of the lath 3 to form a base mesh plate a. The base mesh plate a is installed upright in the opening 4 of the structure, and the pillar is formed around the opening 4 and
It is locked by an anchor 5 that is planted on a beam or floor. After that, mortar or concrete is sprayed on both sides of the base mesh plate a one by one side or simultaneously on both sides to form a mortar or concrete layer b having a required thickness in which the base mesh plate a is embedded in the center.

The structure of the sprayed wall of the present invention is as follows. A base mesh plate a formed by abutting and overlapping the wire nets 1 and 2 on both sides of the lath 3 is locked to the opening 4 of the structure by anchors 5 that are planted around the outside. The base mesh plate a is embedded in the center of the sprayed mortar or concrete layer b having a required thickness.

[0007]

According to the wall construction method by spraying of the present invention, after the ground mesh plate formed by abutting and overlapping the wire mesh on both sides of the lath is erected at the opening of the structure and locked by the anchor, By spraying mortar or concrete on both sides of the ground mesh plate a, the wall of the present invention in which the ground mesh plate is buried in the center of the sprayed mortar or concrete layer, without requiring much human labor as in the conventional case, Simple work can be built in a short period of time and therefore very economically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. 1,2
Is a metal mesh having a rectangular outer shell formed by vertical and horizontal stripes, for example, 100 mm on a side, and 3 is a metal lath, wire lath, etc. This is Russ.

These are set in a state in which the lath 3 is sandwiched between the metal nets 1 and 2, in other words, in a state in which the metal nets 1 and 2 are contact-polymerized on both sides of the lath 3 to form the ground mesh plate a. Is.

This ground mesh plate a may be manufactured in a factory and then carried into a construction site for use, or
Alternatively, the wire nets 1 and 2 and the lath 3 may be individually carried into a construction site, and each of them may be assembled as a base mesh plate a while standing in the opening of the concrete structure.

FIG. 1 shows a state in which a base mesh plate a is erected in an opening 4 of a concrete structure, and 5 is an anchor planted on a pillar, a beam, a floor or the like surrounding the opening 4. By locking the outer peripheral portion of the base mesh plate a with the tip of the anchor 5, the base mesh plate a is firmly fixed to the opening 4.

FIG. 2 is for explaining the situation in which the wire nets 1 and 2 and the lath 3 individually carried into the construction site are set up in the opening 4, and the tip of the anchor 5 is located in the mesh around the outside of the wire mesh 1. The wire mesh 2 is superposed on the wire mesh 1 through the lath 3 through the portion 6, and the tip portion 6 is passed through the mesh around the wire mesh 2 and the tip portion 6 is used with an appropriate tool such as a hammer. By bending (see FIG. 3), the base mesh plate a is opened 4
Fixed to the set.

Thereafter, mortar or concrete is sprayed onto both side surfaces of the base mesh plate a one by one or simultaneously on both sides to form a mortar or concrete layer b having a required thickness. As a result, the intended wall A having the underlying mesh plate a embedded therein is constructed.

[0014]

As is clear from the above description,
The present invention has the following effects. After the ground mesh plate formed by contact polymerization of the wire mesh on both sides of the lath is erected at the opening of the structure and locked by the anchor, by spraying mortar or concrete on both sides of the ground mesh plate, The durable wall of the present invention in which the ground mesh plate is embedded in the center of the spray mortar or concrete layer can be easily constructed.

Unlike the conventional cast-in-place concrete construction method, no additional work such as assembling and dismantling of the formwork is required, so that no skilled worker is required and a small number of people can construct a desired wall in a short time. Because it is possible, the cost is low and it is economical. Further, unlike the case where the conventional precast concrete board is used, there is no disadvantage such as on-site transportation of heavy objects and mounting.
