Description
Technical Field
The utility model relates to a concrete product, in particular to a micro-expansion filler made of high-performance quick-setting concrete.
Background
The filler is a general name of a large class of materials used for gap filling. For example, chinese patent discloses a lightweight material module for use as a concrete floor and filler, patent No. 2010202671845, which describes: a lightweight material module for use as a concrete floor form and filler, comprising: the module is a prefabricated concave main body, two ears of the main body are provided with a box body, a small partition board is arranged in the box body to divide the box body into a plurality of small cavities, a movable cover plate is arranged on the box body, a small partition is arranged in a groove of the main body, and concave-convex tongues and grooves are arranged on two side surfaces of the main body. A plurality of small cavities partitioned in the main body box body are arranged in a honeycomb manner, 1 to 4 small partitions are arranged in the main body groove, and the bottom surface of the main body bottom plate is provided with embossed raised pattern group grids. The embossed pattern group lattices are wavy embossed pattern group lattices, linear embossed pattern group lattices, pointed embossed pattern group lattices or drop embossed pattern group lattices, and the embossed pattern group lattices are arranged in a staggered manner. The module concave main body is prefabricated by adopting a light material. The modules can be connected through concave-convex tongues and grooves to form a whole, in the construction process, the connected modules are placed on the support, the cover plate is covered, concrete is cast, the connected modules can be used as wood templates or steel templates, embossed raised pattern group lattices arranged on the bottom surface of the main body bottom plate are used for increasing the bonding effect of coating mortar in the later construction period, the weight and the engineering cost of the floor slab are greatly reduced by the concrete replaced by the modules, and the heat preservation, the heat insulation and the sound insulation performance of the floor slab are improved by the modules which are prefabricated by light materials and provided with small cavities.
The technical scheme has the following defects that: 1. the cover plate is movable and is not provided with a limiting mechanism, and the cover plate can be flushed out of the box body at a high probability when concrete is poured; 2. the whole structure is formed by concrete, and as is known, the phenomenon of volume reduction inevitably occurs in the early stage of the coagulation of common concrete or the hardening process, so that gaps may occur between the cover plate and the box body due to shrinkage, and the subsequent concrete pouring operation is influenced.
Disclosure of Invention
Not enough to prior art, the utility model provides a apron is difficult to break away from stopping of box.
The technical scheme of the utility model is that:
the micro-expansion filling material prepared from the high-performance quick-setting concrete is characterized in that: the concrete pouring device comprises a concave main body, wherein a plurality of partition plates are uniformly arranged in the concave main body, the upper part of the concave main body is inwards provided with a flange, a cover plate is movably arranged above the partition plates and is in a convex shape, the left and right ends of the lower part of the cover plate are contacted with the inner wall of the concave main body, the lower end surface of the cover plate is contacted with the top of the partition plate, and the left and right ends of the upper part of the cover plate are contacted with the flange; the concave main body and the cover plate are both made of high-performance micro-expansion concrete products, and the concrete products are not easy to shrink greatly.
In some embodiments, the left side wall of the concave main body is provided with a groove, and the right side wall of the concave main body is correspondingly provided with a groove protrusion, so that adjacent filling materials are connected into a plate shape, and the overall strength is increased.
In some embodiments, the top surface of the cover plate and the bottom surface of the concave body are provided with a plurality of anti-slip protrusions, which are advantageous in that they are prevented from slipping during transportation and storage, and can be combined with concrete more firmly when the concrete is poured.
In some embodiments, the cover plate is semicircular on both left and right sides of the upper and lower portions. Because the concrete product is different from metal or plastic, the surface of the concrete product is rough, the semicircular shape can reduce the contact force of the cover plate and the inner wall of the concave main body, so that the force required by the movement of the concrete product is reduced, and the rabbet bulge is arc-shaped.
The utility model has the advantages that: carry on spacingly through the apron of flange to the type of protruding, the apron is difficult to break away from the spill main part when receiving the impact force of pouring concrete or mortar, and whole spill main part all adopts the little expanded concrete that is difficult to take place the shrink with the apron to make, reduces because the dimensional change that self shrink produced.

FIG. 2 is a schematic view of the structure of FIG. 1 with the cover plate removed;
fig. 3 is a schematic structural view of embodiment 2.
In the figures, 1, a concave body; 2. a partition plate; 3. a cover plate; 4. a flange; 5. a groove; 6. the tongue-and-groove is convex; 7. and (4) anti-skid bulges.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in figures 1 and 2, the micro-expansion filler made of high-performance quick-setting concrete is characterized in that: the concrete pouring device comprises a concave main body, wherein a plurality of partition plates are uniformly arranged in the concave main body, the upper part of the concave main body is inwards provided with a flange, a cover plate is movably arranged above the partition plates and is in a convex shape, the left and right ends of the lower part of the cover plate are contacted with the inner wall of the concave main body, the lower end surface of the cover plate is contacted with the top of the partition plate, and the left and right ends of the upper part of the cover plate are contacted with the flange; the concave main body and the cover plate are both made of high-performance micro-expansion concrete products, and the concrete products are not easy to shrink greatly. The high-performance micro-expansion concrete is micro-expansion compensation shrinkage ultrahigh-performance concrete disclosed in Chinese patent and a preparation method thereof, and is the micro-expansion compensation shrinkage ultrahigh-performance concrete recorded in application number 201710372898.9.
