[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. As long as the effect of the utility model can be exerted, various changes can be made to the implementation scheme.

[0032] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0033] Reference Figure 1-8 An assembled lightweight composite thermal insulation board for construction according to this implementation scheme is described.

[0034] The existing lightweight composite thermal insulation board includes a board body 1, in which horizontally and vertically staggered force-bearing connecting steel bars 2 and embedded distribution steel bars 3 are pre-embedded, and connecting grooves are respectively provided at the top and bottom of the board body 1. When connecting, rivets or T-bolts are fixed in the connecting grooves to form a connection between two adjacent board bodies 1.

[0035] In this embodiment, the outer insulation board 9 is fixed to the inner and outer surfaces of the board body 1 to form a composite board, and the board has insulation and certain sound insulation functions. The outer insulation board 9 is fixed to the board body 1 through a fixed connector. The fixed connector is a rod body, and the two ends of the rod body are respectively connected to the outer insulation board 9 and the board body; wherein, the end connected to the board body 1 is a threaded structure; the end connected to the outer insulation board 9 passes through the outer insulation board 9 and is fixed to the board body 1 through a nut and a gasket.

[0036] The plate body 1 is provided with grooves 4 in the circumference; when two adjacent plate bodies 1 are butted against each other, prefabricated connection blocks 5 are inserted into the two opposite grooves 4, and the prefabricated connection blocks 5 fit with the wall surface of the grooves 4. When set, the prefabricated connection blocks 5 are located at the two ends of the adjacent plate bodies 1 that are butted against each other, forming a two-point support; a filling cavity 8 is formed in the groove 4 and between the two prefabricated connection blocks 5, and a filler is arranged in the filling cavity 8; the filler includes a cast body and a filling insulation board 6 filled in the filling cavity 8, and the filling insulation board 6 is fixed in the cast body by the steel bar connecting section 21, and the cast body is a building mortar. After casting, the filling insulation board 6 is limited in the filling cavity 8, and the filling cavity 8 is filled with building mortar for construction, and the building mortar contacts the steel bar connecting section 21 and the gaps around the prefabricated connection blocks 5, so that the two adjacent plate bodies 1 are completely fixed against each other, and the butt joint has a heat preservation function to reduce heat loss.

[0037] The outer side of the filling cavity 8 is blocked by a cover plate 7, and through holes are opened in the upper and lower parts of the cover plate 7; the outer wall surface of the cover plate 7 is flush with the outer wall surfaces of the two adjacent plate bodies 1. In the specific implementation process, the filling cavity 8 is blocked by the cover plate 7 before pouring the building mortar, and the slurry delivery pipeline is connected to the through hole at the bottom of the cover plate 7 to carry out the slurry delivery operation. When the slurry flows out from the upper through hole, it means that the filling cavity 8 has been filled. At this time, the upper through hole is blocked. When the mortar overflows from the top, the slurry delivery operation is stopped, and the lower through hole is blocked.

[0038] In order to improve the connection fixation, one end of the stress-bearing connecting steel bar 2 protrudes from the plate body 1 and is connected to the filler; both ends of the embedded distribution steel bar 3 protrude from the plate body 1 and are connected to the prefabricated connection block 5. The part of the embedded distribution steel bar 3 protruding from the plate body 1 is located on both sides of the part of the stress-bearing connecting steel bar 2 protruding from the plate body 1; one end of the stress-bearing connecting steel bar 2 protruding from the plate body 1 extends out of the groove 4 and is inserted into the filling cavity 8; the part of the embedded distribution steel bar 3 protruding from the plate body 1 is formed in the groove 4. The above arrangement can improve the connection fixation between the plate body 1 and the filler and the prefabricated connection block 5.

[0039] Specifically, the embedded distribution steel bar 3 includes a rod body and a steel bar insertion section 31 protruding from the plate body 1; the prefabricated connection block 5 is pre-opened with an opening, and the steel bar insertion section 31 is inserted into the opening. The opening and the steel bar insertion section 31 achieve a pre-fixing effect when the two opposite plate bodies are butt-jointed.

[0040] The force-bearing connecting steel bars 2 include a steel bar embedded portion embedded in the plate body 1 and a steel bar connecting section 21 extending out of the plate body 1. The steel bar connecting sections 21 in two adjacent plate bodies 1 are staggered or relatively arranged on the filler.

[0041] The embedded steel bar portion includes an embedded steel bar section 23 ; the embedded steel bar section 23 is connected to the steel bar connecting section 21 by bending through the bending section 22 , or the embedded steel bar section 23 is directly connected to the steel bar connecting section 21 .

[0042] It should be noted that when the pre-embedded steel bar portion has a curved section 22, the curved sections 22 at both ends of the plate body 1 need to be bent in opposite directions so that when two adjacent plate bodies 1 are butted, the steel bar connecting sections 21 can be staggered through the curved sections 22. When the pre-embedded steel bar portion does not have a curved section 22, the pre-embedded steel bar section 23 is directly connected to the steel bar connecting section 21, that is, it is an integral steel bar, and the steel bar connecting sections 21 of two adjacent plate bodies 1 are opposite.

[0043] like Figure 6As shown, when the embedded steel bar section 23 is connected to the steel bar connecting section 21 by bending the bending section 22, the steel bar connecting sections 21 in the two adjacent plate bodies 1 are staggered, and the staggered steel bar connecting sections 21 sandwich the filling insulation board 6. It should be noted that the filling insulation board 6 is inserted between the two staggered steel bar connecting sections 21 and clamped by the two steel bar connecting sections 21. The main purpose is that when pouring mortar, the filling insulation board 6 will not be displaced by the impact of the mortar, ensuring that the filling insulation board 6 can be in a preset position, avoiding the occurrence of a high heat loss rate at the connection gap between the two adjacent plate bodies 1 due to the displacement of the filling insulation board 6.

[0044] like Figure 7 As shown, when the embedded steel bar section 23 is directly connected to the steel bar connecting section 21, the steel bar connecting sections 21 in the two adjacent plate bodies 1 are arranged opposite to each other, and the oppositely arranged steel bar connecting sections 21 are inserted into the filling insulation board 6. This method simplifies the processing and construction steps of the force-bearing connecting steel bars 2. When connecting, the two opposite force-bearing connecting steel bars 2 need to be inserted into the filling insulation board 6 to fix the filling insulation board 6, so as to avoid the displacement of the filling insulation board 6 and ensure that the filling insulation board 6 can be in the preset position.

[0045] Working principle: When two plate bodies 1 are butt-jointed, there are two situations: upper and lower butt-jointed and left and right butt-jointed. Since the groove 4 is circumferentially opened on the plate body 1, and the force-bearing connecting steel bars 2 and the embedded distribution steel bars 3 are also arranged in the body 1 in a horizontally and vertically staggered manner, and are all protruding, the connection method used in upper and lower butt-jointed or left and right butt-jointed is the same construction method, which specifically includes:

[0046] When connecting, two adjacent plate bodies 1 are arranged opposite to each other, and prefabricated connection blocks 5 are placed at both ends of the relative joints. It should be noted that at this time, the steel bar insertion section 31 of the embedded distribution steel bar 3 needs to be inserted into the reserved opening of the prefabricated connection block 5; then the filling insulation board 6 is placed into the filling cavity 8 between the two prefabricated connection blocks 5, and the filling insulation board 6 is fixed by the steel bar connection section 21 (fixed by clamping or insertion); at this time, the cover plate 7 on both sides of the filling cavity 8 is covered to form a relatively closed cavity of the filling cavity 8. The slurry delivery pipeline is connected to the through hole at the bottom of the cover plate 7 for slurry delivery operation. When the slurry flows out from the upper through hole, it means that the filling cavity 8 has been filled. At this time, the upper through hole is blocked. When the mortar is observed to overflow from the top, the slurry delivery operation is stopped, and the lower through hole is blocked.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
