DETAILED DESCRIPTION

[0032] like Figure 1-9 As shown, a mold for producing concrete blocks for construction includes a bottom plate 5, a first side plate 1 and a second side plate 2 respectively arranged on two opposite sides of the bottom plate 5, a third side plate 3 and a fourth side plate 4 respectively arranged on the other two sides of the bottom plate 5, a top plate 60 arranged on the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, and an outer frame 6 that frames the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 from the outside. The bottom plate 5, the first side plate 1, the second side plate 2, the third side plate 3, the fourth side plate 4, and the top plate 60 enclose a space corresponding to the shape of the concrete block. The outer frame 6 can be a whole or a combination of each independently; it fixes the position of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4. The first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 do not need to be fixed to the bottom plate 5, but only need to be placed at a predetermined position of the bottom plate 5 and fixed by being covered with the outer frame 6. Whether it is done manually or by automated equipment, the mold is very convenient to assemble and disassemble, and has a simple structure and low cost.

[0033] The bottom plate 5 is in the shape of a flat plate. On the upper surface of the bottom plate 5, there are protruding strips arranged in an I-shaped pattern corresponding to the mortises of the building block 8, which are called the first protruding strip 51, the second protruding strip 52, and the third protruding strip 53. The third protruding strip 53 is arranged between the first protruding strip 51 and the second protruding strip 52. Preferably, the first protruding strip 51 and the second protruding strip 52 are parallelly distributed, and the third protruding strip 53 is perpendicular to the first protruding strip 51 and the second protruding strip 52. Both ends of the third protruding strip 53 are respectively connected to the first protruding strip 51 and the second protruding strip 52. The first side plate 1 and the second side plate 2 are respectively arranged at both ends of the first protruding strip 51 and the second protruding strip 52; the third side plate 3 and the fourth side plate 4 are respectively arranged on both sides of the third protruding strip 53. The bottom plate 5, the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 enclose a shaping space with an I-shaped cross-section. The first protruding strip 51 and the second protruding strip 52 position the first side plate 1 and the second side plate 2. The third protruding strip 53 positions the third side plate 3 and the fourth side plate 4. The I-shaped cross-section of the shaping space is larger than the I-shaped pattern formed by the protruding strips, so that a mortise and tenon structure appears at the edge of the building block. The protruding strips are fixedly arranged on the bottom plate 5. This situation is suitable for the building block 8 with a generally I-shaped shape.

[0034] The first side plate 1 and the second side plate 2 are in the shape of flat plates, and there are flanges 21 at both ends or one end thereof. In the working state of the mold, the flat surfaces are respectively in contact with the outer side surfaces of the first protruding strip 51 and the second protruding strip 52. The cross-sections of the third side plate 3 and the fourth side plate 4 are in the shape of a C, and they are respectively back against both sides of the third protruding strip 53. Both ends of the C shape are respectively in contact with the first side plate 1 and the first side plate 2 or their flanges 21. The lengths of the flanges 21 at both ends of the first side plate 1 and the second side plate 2 can be set as required, as long as the realization of the entire mold shape is ensured. Preferably, the length of the flange 21 is greater than the width of the first protruding strip or the second protruding strip. The third side plate 3 and the fourth side plate 4 can also have flanges at both ends or one end, and the flange 21 is in contact with the flange of the first side plate 1 or its flange or the flange 21 of the second side plate 2. The purpose of these flanges is to make the I-shaped cross-section of the shaping space larger than the I-shaped pattern formed by the protruding strips, so that a mortise and tenon structure appears at the edge of the building block. The structures of the first side plate 1 and the second side plate 2 can be set to be the same or symmetrical. The structures of the third side plate 3 and the fourth side plate 4 can also be the same or symmetrical.

[0035] As Figure 6-9 shown, at least one positioning groove 10 is respectively arranged on the bottom surfaces of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, and positioning protrusions 56 are arranged at the corresponding positions on the bottom plate 5. Or positioning protrusions are arranged on the bottom surfaces of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, and positioning grooves are arranged at the corresponding positions on the bottom plate. The length directions of the positioning protrusions 56 or the positioning grooves 10 on the bottom plate 5 ensure that the left and right positions of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are always correct during the process of being pushed in, taken out, or working. Of course, other left-right direction positioning mechanisms can also be set.

[0036] As shown Figure 1-5 in FIG. 2, the outer frame 6 can be an integral body, and the top plate 60 is arranged on the top of the outer frame 6. The cross-sectional shape of the outer frame 6 corresponds to the cross-sectional shape of the outer sides of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4. The outer frame 6 forms a space with an I-shaped outline corresponding to the outer outline surrounded by the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4; a handle 61 is arranged on the outer frame 6. The shape of the top plate 60 corresponds to the shape of the bottom surface of the building block 8. One side of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 is closely adjacent to the first rib 51, the second rib 52, and the third rib 53 for limiting, and the other side is limited by the outer frame 6, so that the position is fixed. The handle facilitates the manual or machine picking and placing. The handle 61 can be replaced by a lug or a groove, etc., as long as the purpose can be achieved.

[0037] As shown Figure 6-9 in FIG. 3, the outer frame 6 can be separated. The third side plate 3 and the fourth side plate 4 are in a C-shaped cross-section and are respectively back-to-back on both sides of the third rib 53. Support frames 9 are respectively arranged in the C-shaped grooves of the third side plate 3 and the fourth side plate 4, and the top plate 60 is arranged at the top of the support frames 9. The outer frame 6 is at least one quadrilateral structure arranged outside the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4; the quadrilateral mechanism includes two fixing bars 62 respectively arranged on the first side plate 1 and the second side plate 2 and extending beyond the edges of the first side plate 1 and the second side plate 2 at both ends, and two connecting bars 63 detachably connecting the two fixing bars 62. The fixing bars 62 can be welded on the first side plate 1 and the second side plate 2, or can be fixed in a detachable manner. There are various connection methods between the connecting bars 63 and the fixing bars 62, such as bolt connection, or grooves are arranged at both ends of the fixing bars 62, and both ends of the connecting bars 63 are placed in the grooves for connection; or a mutual mortise method is used for temporary fixed connection. The fixing bars 62 can be steel bars, and the connecting bars 63 can be angle steels. The top plate 60 can be one, and both ends are respectively connected to the two support frames 9 in the two C-shaped grooves; or it can be two separate top plates 60. Whether it is one or two top plates is determined according to the shape above the building block.

[0038] In addition, handles 61 are arranged on the outer sides of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4, which is convenient for pulling. Handles 61 can also be arranged on the outer sides of the support frames 9.

[0039] As shown Figure 4-5 in FIGS. 8 and 9, for the building block 8 with a C-shaped cross-section, a partition 7 perpendicular to the bottom surface of the bottom plate 5 can be arranged on the third rib 53 of the bottom plate 5, and both ends of the partition 7 extend to the outer edge positions of the first rib 51 and the second rib 52; the partition 7 divides the bottom plate 5 and the rib into two parts and divides the I-shaped modeling space into two C-shaped modeling spaces. Two C-shaped building blocks 8 can be made at one time.

[0040] The third convex strip 53 is provided with a partition groove 55 at a position corresponding to the partition 7, and the partition 7 is placed in the partition groove 55. The first side plate 1 and the second side plate 2 may also be provided with a partition groove 55 at a position corresponding to the partition 7, so as to further position the partition 7 and stabilize the position of the partition 7. In this structure, the partition 7 is separated from the bottom plate 5, and when necessary, they are assembled together. The manufacturing of the mold is relatively simple. Of course, the partition 7 and the bottom plate 5 can also be manufactured together during the manufacturing process or welded together later.

[0041] Figure 1-5 There are four embodiments of the mold. The top plate 60 of embodiment 1 is different from that of embodiment 2. Embodiment 3 has a partition 7. The shapes of the first ridge 51 and the second ridge 52 of embodiment 4 are different. Figure 10-17 Five examples of building blocks are given. The difference between examples 1 and 2 is whether there is a U-shaped hole. Example 3 is a building block with a U-shaped cross section. The difference between examples 4 and 5 and examples 1 and 2 is the length of the two parallel sides of the I-shaped. The mold of the building block 8 in these examples can be achieved by simply changing the length and shape of the first convex strip 52, the second convex strip 53 on the bottom plate 5 of the mold, the shape of the top plate 60, etc. Changes in the size of the building block can be achieved by simply changing the mold. Figure 6-8 and Figure 1-5 The differences lie in the outer frame 6 and the base plate 5 .

[0042] In specific implementation, the first side panel 1 and the second side panel 2 are slid along the positioning protrusion 56 to their larger planes against the outer side surfaces of the first convex strip 51 and the second convex strip 52. If there is a partition 7, the partition 7 is first placed in the partition groove 55 of the bottom plate 5. Then the first side panel 1 and the second side panel 2 are moved along the positioning protrusion 56. The third side panel 3 and the fourth side panel 4 are placed with their middle surfaces back against the outer side surface of the third convex strip 53. The third side panel 3 and the fourth side panel 4 are in contact with the first side panel 1 and the second side panel 2. The outer frame 6 is used to cover the outside of the first side panel 1, the second side panel 2, the third side panel 3 and the fourth side panel 4 from top to bottom, or the fixing strip 62 is first fixed to the first side panel 1 or the second side panel 2, and then the connecting strip 63 is installed to form a quadrilateral outer frame 6 to fix the first side panel 1, the second side panel 2, the third side panel 3, and the third side panel 4. After the concrete material is poured and the blocks 8 are formed, the outer frame 6 is removed, and the first side plate 1, the second side plate 2, the third side plate 3, the fourth side plate 4 and the blocks 8 are taken out.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
