Abstract

The invention discloses a slotted embedded block and a damping filling wall containing the block. The block includes a block body. The block body includes three sets of facings, and each set of facings has two parallel brick faces. Composition, corresponding grooves and protrusions are provided on at least two brick faces of a group of facings, the height of the protrusions is smaller than the groove depth of the grooves, and the side length of the protrusions is smaller than the inner groove side length of the grooves size. The damping filling wall is made of block bodies to form a damping filling wall. The protrusions of the blocks are embedded in the grooves of the adjacent blocks, and the protrusions and the grooves are sealed by a damping layer. Slotted insert blocks increase in-plane and out-of-plane mechanical snap compared to traditional damped infill walls. At the same time, it is more reliable than the traditional damping filling wall, which needs to rely on glue to bond the damping material and concrete material, and the process is simple. The contact surface and the ability of mechanical interlocking are further improved.

Description

Slotted in-line blocks and damped infill walls containing the blocks

technical field

The invention belongs to the field of building materials, in particular to a building block and a damping filling wall made of the block.

Background technique

When masonry is used to build building masonry, clay bricks, concrete bricks, lime sand bricks and aerated bricks are usually used to make building masonry. Wherein, the bricks in the shape of a cuboid are arranged horizontally, and the bricks are staggered sideways by half bricks in the vertical direction. Thereby, the so-called horizontal joints that are continuous in the horizontal direction are produced, while the vertical joints on the side of the bricks are constructed to be mutually laterally staggered in the vertical direction, so that the vertical joints are staggered and interrupted each other. The structure has poor earthquake resistance. To improve the resistance and stability of buildings during earthquakes, continuous horizontal joints in masonry as described above have proven problematic. Beneficiary load tests lead to fractures along horizontal masonry joints and thus even masonry collapse under extreme loads.

At present, there is a kind of block with anti-seismic function, which is a wave block, and adjacent wave blocks are mechanically frictionally connected by the contact surfaces between the blocks. Such a structure achieves the anti-seismic effect purely by the friction between the blocks. It has no damping layer, has poor power consumption, and has poor anti-seismic ability.

Another is to design a damping infill wall with an anti-seismic function. Generally, the damping material and concrete blocks are bonded together through structural adhesives. The process is complicated and raw materials are wasted. On the other hand, the concrete block and the damping material are regular structures that are simply bonded to each other, and the bonded joints are also horizontal joints. Although there are damping materials, it has a certain anti-seismic effect, but because its structure is a horizontal or vertical bonded joint at the plane, there are still great deficiencies in the anti-seismic performance.

Contents of the invention

In order to solve the above problems, the present invention provides a slotted embedded block and a damping filling wall containing the block. Using the block of the present invention can easily and quickly build the wall, and at the same time, the damping filling wall built by masonry has High shock resistance.

The purpose of the present invention is achieved in the following manner:

A slotted embedded block, including a block body, the block body includes three sets of facings, each set of facings is composed of two brick faces parallel to each other, at least two brick faces of one set of facings Corresponding grooves and protrusions are provided, the height of the protrusions is smaller than the groove depth of the grooves, and the side length of the protrusions is smaller than the side length of the inner groove of the groove.

According to different needs, the shape of the protrusion of the present invention is any one of cylinder, triangle, polygon, and ellipse, and the shape of the corresponding groove is also consistent with the shape of the protrusion.

According to the needs of different working conditions, corresponding grooves and protrusions can be provided on both sets of facings. Corresponding grooves and protrusions can also be provided on the three sets of facings.

For good plasticity, the block body of the present invention adopts aerated concrete block.

A damping filling wall containing the above-mentioned slotted embedded blocks, the damping filling wall is built by the block body, the protrusions of the blocks are embedded in the grooves of the adjacent blocks, and the protrusions and the grooves are separated by The damping layer is sealed.

The improved solution is: the damping layer is formed by filling asphalt ointment between the protrusions and the grooves.

The preferred solution is: the gap between the protrusion and the groove is 2-5mm.

The best solution is: the gap between the protrusion and the groove is 3mm.

Advantages compared to traditional damping infill walls and corrugated built-in blocks:

The ointment is used as the damping layer, which has good flexibility. In the cold winter, the ointment remains flexible and plastic without cracks; it is heat-resistant and does not flow or fall under the sun in summer; it has strong adhesion and can be used with all metals, concrete, etc. The material is firmly bonded; the waterproof and moisture-proof performance is good, it is not easy to age, and it is durable. Because asphalt ointment has strong fluidity, good energy dissipation performance, low price and strong bonding ability with concrete, it is a good energy dissipation material, but its shear resistance and bearing capacity are poor, so in ordinary damping Infill walls are not the best material, but can be used to their full advantage in circular channel inset blocks. Moreover, with the limitation of the scope of the groove, it is not easy to cause excessive sinking due to insufficient bearing capacity.

Circular slot inset blocks increase in-plane and out-of-plane mechanical snap compared to conventional damped infill walls. At the same time, it is more reliable than the traditional damping filling wall, which needs to rely on glue to bond the damping material and concrete material, and the process is simple. The contact surface and the ability of mechanical interlocking are further improved.

The aerated concrete block is selected as the base material, which has good plasticity and can be produced according to the designed shape and design formwork, which is conducive to large-scale production of the factory and improves its practicability.
