Description

Energy-saving and environment-friendly wall brick and method for building wall thereof

technical field

The invention relates to the construction field, in particular to an energy-saving and environment-friendly wall brick and a wall-building method thereof.

Background technique

In order to protect land resources and ecological environment, save energy, and promote the development of circular economy, wall insulation materials are new wall materials developed in recent years, which can save a lot of wall materials, improve wall insulation performance, save resources, and reduce environmental pollution. In terms of new wall materials, there are hollow blocks, aerated blocks, gypsum hollow blocks, aerated fly ash bricks, porous clay bricks, GRC wall panels, reinforced fiber cement boards, sandwich panels, and fly ash Air wall panels and composite insulation wall panels can be said to be of various types. At present, there is a composite wall brick on the market, which includes an inner wall and an outer wall. The inner wall and the outer wall are connected through a connecting plate, which can form a cavity between the inner wall and the outer wall, and Pouring lightweight foamed concrete into the space has met the requirements of thermal insulation. However, this kind of lightweight foamed concrete needs to be sealed under high-temperature steam for a long time to make the foaming material expand, and it is impossible to wrap a wall or a whole building in a closed airtight way to pass high-temperature and high-pressure air into it at the construction site. Water vapor is used to meet the expansion of the foaming material, which will lead to poor foaming quality of the foamed concrete, which will affect the thermal insulation effect of the wall.

Contents of the invention

Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is: how to provide an energy-saving and environment-friendly wall brick with simple structure, good thermal insulation effect and easy fabrication.

In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

An energy-saving and environment-friendly wall brick, comprising an inner wall and an outer wall, a connecting plate for connecting the inner wall and the outer wall is arranged between the inner wall and the outer wall, and the inner surface of the outer wall is covered with a layer The foam insulation board is characterized in that: the foam insulation board is set apart from the inner wall, and the end of the connecting plate close to the outer wall is provided with at least one strip-shaped hole extending along the vertical direction, and the strip-shaped hole extends along the horizontal direction. The projection is located in the projection of the foam insulation board along the horizontal direction, and the foam insulation boards located on both sides of the connecting plate can be integrally formed and connected together through the strip-shaped holes.

In the present invention, the foamed thermal insulation board is processed simultaneously in the process of making wall bricks, and at the same time, the foamed thermal insulation board is separated from the inner wall, so that a cavity can also be formed after the wall is built. In order to pour concrete into it, it can not only meet the strength requirements of the wall, but also meet the requirements of thermal insulation. In addition, the foam insulation board has been formed when the brick body is made, which makes the production easier, and can also avoid poor thermal insulation effect caused by quality problems, and also reduces the difficulty of on-site wall construction. The connection plate is used as a heat conductor for heat transfer, and the arrangement of strip holes can block the cold bridge effect and enhance the thermal insulation effect inside the building. During the molding process, the foam insulation board passes through the strip holes and is integrally formed and connected together to form a whole with stronger stability. In addition, it can also reduce the heat conduction of the inner and outer walls.

As an optimization, there are two connecting plates spaced apart from each other, and the connecting plates are arranged vertically and away from the horizontal ends of the inner wall and the outer wall. In this way, not only a cavity for pouring concrete is formed in the same wall brick, but also a cavity for pouring concrete can be formed between two adjacent wall bricks, and the thermal insulation and strength can be improved.

As an optimization, a plurality of perforations through which steel bars can pass are provided at intervals along the vertical direction on the connection plate between the foam insulation board and the inner wall. The perforation can make the steel bar pass through, so that the steel bar forms a closed ring beam structure between the inner and outer walls, further increasing the stability of the wall. In addition, steel bars and post-cast concrete coexist to form an integral reinforced concrete shear wall, which increases the shear and tensile strength of the wall.

As an optimization, the end surface of the inner wall body located at one end in the horizontal direction is provided with a tenon extending in the vertical direction, and the other end is provided with a groove capable of engaging the tenon. When building a wall, two adjacent wall bricks can be inserted into the groove through the protruding tenon, and bonded together with cement mortar as an adhesive, which increases the gap between the two wall bricks. The strength and stability of the connection.

The invention also discloses a method for building a wall, which includes the following steps:

1) Draw the reference line for wall construction on the ground, and then evenly lay a layer of mortar concrete cushion on the ground inside the reference line;

2) Build a layer of wall bricks on the mortar concrete cushion according to the position of the reference line, the wall bricks are the energy-saving and environment-friendly wall bricks described in any one of claims 1 to 5, and two adjacent wall bricks They are connected together by mortar concrete. The tenon at one end of the inner wall of the wall brick is matched with the groove at one end of the inner wall of the adjacent another wall brick, and the groove at the other end is matched with the adjacent other wall brick. The tenons on the inner wall of a wall brick are matched, and the outer sides of the wall bricks at both ends of the wall are sealed by sealing bricks, and then concrete is poured into the cavity inside the wall brick and compacted;

3) Apply a layer of mortar concrete on the top surface of the upper layer of wall bricks and build a layer of wall bricks. The adjacent two wall bricks are connected by mortar concrete. The foam insulation boards are bonded together by an adhesive. The tenon at one end of the wall brick matches the groove at one end of the adjacent wall brick, and the groove at the other end matches the card on the adjacent wall brick. The tenons are matched, and the outer sides of the wall bricks at both ends of the wall are sealed with sealing bricks, and then concrete is poured into the cavity inside the inner wall bricks and compacted;

4) Repeat step 3 until the wall reaches the design height;

5) The wall is plastered and leveled.

As an optimization, in step 2) and step 3), after the wall bricks are built, steel bars are used to pass through the perforations on the wall bricks in sequence, and then the outer sides of the wall bricks at both ends of the wall are sealed with sealing bricks. Finally, pour concrete into the cavity inside the inner wall brick and compact it.

To sum up, the beneficial effects of the present invention are: the present invention is simple in structure, easy to manufacture, and low in cost. Difficulty of wall construction.
