Description

Technical Field

[0001] The invention relates to the technical field of cement foam boards, and in particular to a fireproof and heat-insulating cement foam board and a manufacturing method thereof. Background Art

[0002] Fireproof and thermal insulation cement foam board is an important material for building exterior wall insulation and fire isolation. Its fireproof performance and thermal insulation effect are crucial. Traditional fireproof and thermal insulation cement foam board is mostly a monolithic single board. When used as a splicing unit, the single board size is fixed and lacks an adaptive splicing structure. This design leads to significant problems when splicing to form an integral board: on the one hand, a single board is used as a splicing unit, and because there is no standardized splicing structure such as mortise and tenon, slot, etc., it needs to rely on additional fixings or filling materials when splicing. Not only is the construction cumbersome and inefficient, but it is also easy to produce gaps due to loose splicing, affecting the overall thermal insulation and fireproof performance; on the other hand, because a single board is rigidly fixed to the adjacent boards by bonding or fixings, if a part of the board is damaged due to aging or impact, it cannot be disassembled and replaced separately, forcing the intact part to be discarded together with the damaged part, resulting in excessive waste of raw materials and a large increase in the amount of construction waste generated. Based on this, the present invention purposely provides a fireproof and thermal insulation cement foam board and a manufacturing method thereof that can achieve standardized and convenient splicing, facilitate single-block disassembly and replacement, and improve recycling efficiency.

[0013] Beneficial effects of the present invention: 1. In the present invention, modular panels and connecting blocks are used to connect multiple panels through adjacent connecting blocks. The connection between two connecting blocks is achieved through a snap-fit ​​structure of a slot, a first cavity, and an insert block. This replaces traditional additional fixings, making splicing more convenient and efficient, and reducing gaps. The drive assembly controls the extension and contraction of the insert block, allowing defective panels to be removed and replaced individually, avoiding the disposal of intact panels and reducing resource waste and construction waste. In addition, the treatment of the splicing gap between the two connecting blocks enhances fireproofing and thermal insulation performance, thereby improving overall construction efficiency and achieving the effect of partial panel replacement. 2. In the present invention, a detachable second abutment plate is provided on the first cavity. When the plug block is in a fully extended or fully retracted state, the sliding blocks are located at both ends of the first cavity. In these two states, the second abutment plate is slid into the first cavity. At this time, the second abutment plate abuts the sliding block, thereby preventing the sliding block from moving. As a result, the plug block is also unable to move, thereby achieving the purpose of fixing the plug block, thereby ensuring the stability of the connection between the two connecting blocks through the plug block and the slot; 3. In the present invention, the driving assembly allows the plug-in block to be inserted into the slot. At this time, the second cavity on the plug-in block is aligned with the locking hole, and the spring preload force causes the locking block to be inserted into the locking hole. At this time, the plug-in block and the locking block form an L-shaped card block, which is embedded in the slot and the locking hole. Compared with the individual insertion of the slot and the plug-in block, the cooperation of the locking block and the locking hole can limit the two connecting blocks from moving apart in the lateral direction. Combined with the slot and the plug-in block, the two connecting blocks are limited from moving apart in the longitudinal direction, which can improve the stability of the connection between the two connecting blocks.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figures 1-6 As shown, the present invention is a fireproof and heat-insulating cement foam board, comprising: The plate body 1 has a connecting block 2 fixedly installed on all four sides of the plate body 1. The four connecting blocks 2 are arranged circumferentially and connected end to end. A slot 5 and a first cavity 7 are provided on the side of each connecting block 2 away from the plate body 1. The slot 5 and the first cavity 7 are symmetrically arranged about the plate body 1. An insert block 8 is slidably installed in the first cavity 7. The insert block 8 is driven to move by a driving assembly built into the first cavity 7. The connecting blocks 2 on the two plate bodies 1 are connected through the insert block 8 and the slot 5. When the connecting block 2 on one plate body 1 is aligned with the connecting block 2 on the other plate body 1, the slot 5 on one connecting block 2 is aligned with the first cavity 7 on the other connecting block 2. The driving assembly drives the insert block 8 to move so that the insert block 8 is inserted into the slot 5.

[0019] The working principle of the present invention is as follows: first, a plate body 1 and a connecting block 2 are made by a mold, so that the number ratio of the plate body 1 to the connecting block 2 is 1:4, and then four connecting blocks 2 are fixedly installed on the four sides of the plate body 1 in an end-to-end adjacent manner to form a whole, forming a Figure 1 However, in the initial state, the plug-in block 8 should be retracted in the first cavity 7. Then, multiple plates 1 assembled with the connecting blocks 2 are assembled. The specific operation is to align the connecting blocks 2 on different plates 1, ensure that the slots 5 on one connecting block 2 are aligned with the first cavity 7 on another connecting block 2, and then drive the plug-in block 8 to move by the driving assembly so that the plug-in block 8 is inserted into the slot 5, thereby completing the splicing of different plates 1. Figure 6 The state shown; and when a plate body 1 needs to be replaced, the same operation is performed on the problem plate body 1 and the four plate bodies 1 adjacent to the problem plate body 1, that is, the driving assembly on the four connecting blocks 2 in the groove drives the plug block 8 to move, so that the plug block 8 shrinks into the first cavity 7. At this time, there is no card-connected relationship between the connecting block 2 on the problem plate body 1 and the connecting blocks 2 on the four adjacent plate bodies 1. Then the problem plate body 1 can be taken out in a direction perpendicular to the splicing surfaces of the multiple plate bodies 1, and then the new plate body 1 can be put back between the four plate bodies 1, and the two adjacent connecting blocks 2 can be reconnected to restore it to its original state. Of course, in order to improve the fireproofing and thermal insulation performance, the splicing gaps of the connecting blocks 2 can be processed, including but not limited to filling with fireproof expansion sealant, embedding composite thermal insulation sealing strips, and spraying fireproof thermal insulation foaming agents.

[0020] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, the driving assembly includes a sliding block 14, an inclined groove 15, a straight groove 12 and a round rod 13, the straight groove 12 is opened in the first cavity 7, the sliding block 14 is slidably installed in the first cavity 7, and the sliding block 14 is driven to move by the output source, one end of the sliding block 14 is located outside the connecting block 2, and the end is located on the back of the connecting block 2, the inclined groove 15 is opened on the sliding block 14, the inclined groove 15 is arranged at an angle, and there is an angle between the inclined groove 15 and the straight groove 12, the round rod 13 is fixedly installed on the plug block 8, the round rod 13 is slidably connected to the straight groove 12, and the round rod 13 is slidably connected to the sliding block 14.

[0021] Specifically, the driving assembly also includes a second abutment plate 19 and a second sinking groove 20. The second abutment plate 19 is slidably installed in the first cavity 7, and the second abutment plate 19 and the first cavity 7 are detachably installed. When the second abutment plate 19 is located in the first cavity 7, the second abutment plate 19 abuts against the sliding block 14, so that the position of the sliding block 14 is fixed. The second sinking groove 20 is opened on the connecting block 2, and the second sinking groove 20 is connected to the first cavity 7. When the second abutment plate 19 is located in the first cavity 7, the second abutment plate 19 can be removed through the second sinking groove 20.

[0022] In one case of this embodiment, the output source may be manually driven, or may be other mechanisms capable of achieving linear reciprocating motion, which is not specifically limited in this embodiment.

[0023] In actual application of this embodiment, after the slots 5 on the two connecting blocks 2 are aligned with the first cavity 7, the second abutment plate 19 is first taken out through the second sinking groove 20. At this time, the sliding block 14 can be driven by the output source to move in the first cavity 7, and the movement of the sliding block 14 drives the inclined groove 15 to change its position, so that the round rod 13 slides in the inclined groove 15, and the restriction of the straight groove 12 causes the round rod 13 to slide in the straight groove 12. At this time, the round rod 13 will drive the insertion block 8 to move, thereby inserting it into the first cavity 7. On the contrary, when the output source drives the sliding block 14 to move in the opposite direction in the first cavity 7, it can drive the insertion block 8 to retract to In the first cavity 7, in order to ensure that the plug-in block 8 can be in a fixed and stationary state, a detachable second abutment plate 19 is provided on the first cavity 7. When the plug-in block 8 is in a fully extended or fully retracted state, the sliding block 14 is located at both ends of the first cavity 7. In these two states, the second abutment plate 19 is slidably installed into the first cavity 7. At this time, the second abutment plate 19 will abut the sliding block 14, so that the sliding block 14 cannot move, and the plug-in block 8 cannot move, thereby achieving the purpose of fixing the plug-in block 8, thereby ensuring the stability of the connection between the two connecting blocks 2 through the plug-in block 8 and the slot 5.

[0024] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, a locking hole 6 is provided in the slot 5, a second cavity 10 is provided in the plug block 8, a locking block 9 is slidably installed in the second cavity 10, and the locking block 9 is driven to move by a power component. When the two connecting blocks 2 are connected, the plug block 8 is inserted into the slot 5 so that the second cavity 10 is aligned with the locking hole 6. At this time, the power component drives the locking block 9 to insert into the locking hole 6. When the two connecting blocks 2 are separated, the power component drives the locking hole 6 to shrink into the second cavity 10.

[0025] Specifically, the power assembly includes a spring 11 and an unlocking plate 16. The locking block 9 is connected to the bottom of the second cavity 10 through the spring 11. The pre-tightening force of the spring 11 makes the locking block 9 move away from the second cavity 10. The locking hole 6 passes through the back of the connecting block 2. The unlocking plate 16 is slidably installed in the locking hole 6. One end of the unlocking plate 16 is located outside the connecting block 2, and this end of the unlocking plate 16 is located on the back of the connecting block 2. The unlocking plate 16 is driven to move by the power source. When the locking block 9 is inserted into the locking hole 6, the locking block 9 abuts against the unlocking plate 16. At this time, the unlocking plate 16 is away from the slot 5. When the power source drives the unlocking plate 16 close to the slot 5, the unlocking plate 16 pushes the locking block 9 to compress the spring 11, so that the locking block 9 shrinks into the second cavity 10.

[0026] Specifically, the power assembly also includes a first abutment plate 17 and a first sinking groove 18. The first abutment plate 17 is slidably installed in the locking hole 6, and the first abutment plate 17 and the locking hole 6 are detachably installed. When the first abutment plate 17 is located in the locking hole 6, the first abutment plate 17 abuts against the unlocking plate 16, so that the position of the unlocking plate 16 is fixed. The first sinking groove 18 is opened on the connecting block 2, and the first sinking groove 18 is connected to the locking hole 6. When the first abutment plate 17 is located in the locking hole 6, the first abutment plate 17 can be removed through the first sinking groove 18.

[0027] In one case of this embodiment, the power source may be manually driven, or other mechanisms capable of achieving linear reciprocating motion may be used, which is not specifically limited in this embodiment.

[0028] In practical application, in order to further improve the stability of the connection between the two connecting blocks 2, a locking hole 6 is provided in the slot 5, and a second cavity 10 is provided in the plug block 8, and the bottom of the second cavity 10 is connected to the locking block 9 through the spring 11. In the initial state of the connecting block 2, the locking block 9 is completely retracted in the second cavity 10. At this time, the spring 11 is compressed by the locking block 9, and the plug block 8 is located in the first cavity 7. When the slots 5 and the first cavity 7 on the two connecting blocks 2 are aligned, the plug block 8 is driven by the driving assembly. Inserted into the slot 5, the second cavity 10 on the insert block 8 is aligned with the locking hole 6, and the pre-tightening force of the spring 11 causes the locking block 9 to be inserted into the locking hole 6. At this time, the insert block 8 and the locking block 9 form an L-shaped block, which is embedded in the slot 5 and the locking hole 6. Compared with the insertion of the slot 5 and the insert block 8 alone, the cooperation of the locking block 9 and the locking hole 6 can limit the two connecting blocks 2 from moving apart in the lateral direction. In combination with the slot 5 and the insert block 8, the two connecting blocks 2 are limited to moving apart in the longitudinal direction, which can improve the stability of the connection between the two connecting blocks 2; When the locking block 9 is inserted into the locking hole 6, the locking block 9 will abut the unlocking plate 16. When replacing the connecting block 2, the unlocking plate 16 is first driven by the power source to push the locking block 9 and push the locking block 9 back into the second cavity 10. At this time, the insert block 8 can be driven by the driving component to retract into the first cavity 7. In order to improve the convenience of operation, a detachable first abutment plate 17 is provided in the locking hole 6. When the unlocking plate 16 pushes the locking block 9 back into the second cavity 10, the locking block 9 is pre-tightened by the spring 11 and acts on the unlocking plate 16. Then, the first abutment plate 17 is slidably installed in the locking hole 6, which can limit the movement of the unlocking plate 16, thereby ensuring that the unlocking plate 16 always abuts the locking block 9, so that the unlocking plates 16 on other connecting blocks 2 can be operated.

[0029] like Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, a protrusion 3 is fixedly installed at one end of each connecting block 2, and a groove 4 is opened at the other end of each connecting block 2. The protrusion 3 on one connecting block 2 is slidably engaged with the groove 4 on the other connecting block 2.

[0030] In practical application, if Figure 5As shown in the figure, for example, when the connecting block 2 is installed, a sliding installation method is adopted. When the connecting block 2 is slidably installed, the protrusion 3 at one end thereof will be inserted into the groove 4 of the other connecting block 2, and the groove 4 at the other end of the slidingly installed connecting block 2 will engage with the protrusion 3 on the other connecting block 2. In this way, the four connecting blocks 2 are connected end to end, thereby improving the stability of the connection between the four connecting blocks 2 and the plate body 1. The engagement of the protrusions 3 and the grooves 4 on the four connecting blocks 2 can provide a temporary rigid connection, providing a stable foundation for subsequent connection between the connecting block 2 and the plate body 1 by other means, such as applying glue between the connecting block 2 and the plate body 1, and passing bolts through the connecting block 2 and the plate body 1.

[0031] like Figures 1-6 As shown, as a preferred embodiment of the present invention, a reserved hole 21 is opened at one end of the back side of each connection block 2, and the reserved hole 21 is used to connect the embedded parts.

[0032] In actual application of this embodiment, by providing a reserved hole 21 on the connecting block 2, when an embedded part needs to be replaced, only the corresponding connecting block 2 needs to be replaced, and there is no need to replace the entire plate body 1, thereby reducing the generation of construction waste and saving materials.

[0033] See also Figures 1-6 As shown, the present invention is a method for manufacturing a fireproof and heat-insulating cement foam board, which is applied to a fireproof and heat-insulating cement foam board as described in the above embodiment, and the method comprises the following steps: Step S1: First, a plate body 1 and a connecting block 2 are produced by a mold, so that the ratio of the number of the plate body 1 to the number of the connecting block 2 is 1:4; Step S2: four connecting blocks 2 are fixedly mounted on the four sides of the plate body 1 in an end-to-end manner to form a whole; Step S3: assembling a plurality of plate bodies 1 assembled with connection blocks 2; Step S4: Align the connecting blocks 2 on different plates 1 to ensure that the slot 5 on one connecting block 2 is aligned with the first cavity 7 on the other connecting block 2, and then drive the insert block 8 to move by the driving assembly so that the insert block 8 is inserted into the slot 5, thereby completing the splicing of the different plates 1; Step S5: When a plate 1 needs to be replaced, the problem plate 1 and the four adjacent plates 1 are operated in the same manner, that is, the driving components on the four connecting blocks 2 in the groove drive the plug 8 to move, so that the plug 8 shrinks into the first cavity 7. At this time, the problem plate 1 can be taken out for replacement, and a new plate 1 can be installed and step S4 can be repeated.

[0034] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
