[ detailed description ] embodiments

In order to make the objects, technical solutions and advantageous effects of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

The invention provides a method for preparing a building block, which is used for preparing the building block 100 shown in figures 1 to 3. The block 100 comprises a body 10, a wood frame 20 and a foam core 30, wherein the foam core 30 is clamped in the wood frame 20, and the foam core 30 and the wood frame 20 are embedded in the body 10. The body 10 is rectangular and includes two main faces 11 disposed oppositely and four side faces 12 surrounding the two main faces 11, wherein two adjacent side faces 12 are provided with a slot 121, and the other two adjacent side faces 12 are extended with a protrusion 122.

The preparation method of the building block comprises the following steps: retaining the foam core 30 in the wood frame 20; positioning the foam core 30 in an open lower mold through the wood frame 20; adding slurry mainly formed by mixing cement, lightweight aggregate, slag powder and additives into the lower die; closing the lower die by using an upper die, and forming the slurry in gaps among the foam core 30, the wood frame 20, the lower die and the upper die under natural conditions to obtain the body 10; and demolding to obtain the building block 100.

The cement may be silicate cement, aluminate cement, magnesium cement and other special cement. The lightweight aggregate can be at least one of perlite, vermiculite, rice hull, straw and sawdust. The slag powder can be blast furnace slag, power plant fly ash and various waste ore powder. The additives comprise a coagulant, a retarder, a water reducing agent, a modifier and the like. Preferably, the mass percentages of the cement, the lightweight aggregate, the slag powder and the additive are respectively 30-60%, 10-30%, 5-30% and 0.5-5%. Compared with the prior art, the light aggregate and the slag powder are used as raw materials for producing the building block 100, so that the light and heat-insulating product effect is realized, the mineral resources are saved, and the slag is reasonably utilized to protect the environment.

The lower mold corresponds to two main faces 11 of the block 100, two side faces 12 provided with the protrusions 122, and one side face 12 provided with the locking grooves 121, and the upper mold corresponds to the other side face 12 provided with the locking grooves 121. When the slurry is added to the lower mold, a side of the lower mold corresponding to the clamping groove 121 is a bottom surface contact horizontal plane, for example, a horizontal ground.

The foam core 30 is rectangular and is vertically and suspendedly positioned in the lower mold when the slurry is cast. Specifically, the foam core 30 may be positioned by screwing screws penetrating through the lower mold into the wood frame 20, so that neither the positioned foam core 30 nor the wood frame 20 is in contact with the lower mold. Limiting the position of the foam core 30 is beneficial to improving the strength uniformity of the building block 100, so that the foam core 30 and the wood frame 20 are completely embedded in the body 10, and the screws can be taken out after casting. In addition, the wood frame 20 not only can fix the foam core 30, but also can play a role in reducing weight and toughening.

The block 100 can be used for building a wall, and when a wall is manufactured by using a plurality of blocks 100, the protrusion 12 of each block 100 is inserted into the slot 121 of an adjacent block 100 to form a stable connection relationship. The catch 121 thus corresponds to the shape of the projection 122 to facilitate a nesting fit. Specifically, the locking groove 121 and the protrusion 122 are respectively disposed along the central axis of the corresponding side surface 12, the locking groove 121 and the protrusion 122 are respectively L-shaped, and the locking groove 121 penetrates through the two adjacent side surfaces 12, so that the protrusion 12 of each block 100 is slidably inserted into the locking groove 121 of one adjacent block 100.

Preferably, the volume of the foam core 30 is 1/2-3/4 of the total volume of the block 100. When the volume ratio of the foam core 30 is too high, the block 100 may have insufficient strength, and when the volume ratio of the foam core 30 is too low, the block 100 may have poor heat insulation effect.

Preferably, the width of the body 10 is 30-130cm, the thickness is 5-35cm, and the height is 20-65cm, so as to meet the requirements of the weight and the volume of the single building block 100 during actual construction. The surface of the foam core 30 is provided with a groove 31, and the groove 31 is used for accommodating the wood frame 20. The wood frame 20 is a split structure, so that the foam core 30 is clamped in the wood frame 20.

The invention is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the invention is not limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
