Description
Technical Field
The application relates to the field of external wallboards, in particular to a composite board, an external wallboard and a manufacturing method of the external wallboard.
Background
The related art discloses a fire-retardant sandwich heat preservation coincide wallboard, including stainless steel truss reinforcing bar and interior leaf concrete layer, cavity layer, outer wall heat preservation and the outer leaf concrete layer that from interior to exterior set gradually, the cavity layer is located between interior leaf concrete layer and the outer leaf area heat preservation concrete layer, and the cavity layer adopts cast in situ concrete to make. According to the scheme, the shearing strength between the inner leaf concrete layer and the outer leaf heat-insulating concrete layer is enhanced by arranging the stainless steel truss steel bars, and finally, the heat insulation purpose is achieved through the outer wall heat-insulating layer;
the wall board can effectively solve the shearing resistance and heat preservation of a wall body, but in the actual use process, as cast-in-place concrete is finally needed in the cavity layer, the stainless steel truss steel bar can be pre-stressed in the pre-embedding process, so when the pre-embedded stainless steel truss steel bar is poured in the cavity layer, the concrete around the stainless steel truss steel bar is extremely easy to break under the effect of the pre-stretching stress of the stainless steel truss steel bar, so that the concrete at the cavity layer is not easy to form, and finally, the normal use of the wall board is affected; or the concrete at the cavity layer is easily damaged under the action of the pre-stressing force of the stainless steel truss steel bar after being molded, thereby influencing the service life of the wallboard;
for this reason, it is urgently required to solve the existing problems.
Disclosure of Invention
In order to solve the technical problems, the application aims to provide a composite board, an external wall board and a manufacturing method of the external wall board, so as to solve the technical problems that the existing external wall board does not have a shearing-resistant and heat-insulating effect or has heat-insulating and shearing-resistant effects but has a short service life.
First aspect
To achieve the above object, the present application provides a composite board comprising:
a first panel;
a second panel disposed in parallel with the first panel and formed with a gap;
a truss structure disposed within the gap;
the first panel, the truss structure and the second panel are fixedly connected through a plurality of fasteners.
By adopting the technical scheme, the aim of enhancing the shearing resistance of the composite board can be achieved. The first panel, the truss structure and the second panel are connected and fixed under the action of the fastener, the truss structure has the shearing resistance, and the first panel and the second panel are under the action of the truss structure, so that the shearing resistance of the first panel and the second panel is improved under the action of the shearing force, and finally, the integral shearing resistance of the composite board is realized.
As a further description of the above technical solutions, the truss structure includes:
the outer contour of the rectangular frame is the same as the outer contour of the first panel and the second panel;
a first inclined plate disposed obliquely along a diagonal line of the rectangular frame;
a second inclined plate disposed obliquely along the other diagonal of the rectangular frame;
the rectangular frame, the first inclined plate and the second inclined plate are fixedly connected through the fastener respectively.
By adopting the technical scheme, the aim of further enhancing the shearing resistance of the composite board can be achieved. Because the first inclined plate and the second inclined plate are arranged along the diagonal line of the rectangular frame, the rectangular frame is divided into four triangles under the action of the first inclined plate and the second inclined plate, and the structure of the triangle is stable, so that the whole structure of the truss is stable.
As a further description of the above technical solution, a first through hole is formed at a junction of the first inclined plate and the rectangular frame, a second through hole is formed at a junction of the second inclined plate and the rectangular frame, and a third through hole is formed at a junction of the second inclined plate and the first inclined plate;
the fastener is a screw, and the screw is sequentially connected with the first panel, the first through hole, the second through hole, the third through hole and the second panel in a threaded manner.
By adopting the technical scheme, the aim of enhancing the overall structural stability of the composite board can be achieved. The composite plate is applied to the upstream material of the outer wall plate, and the outer wall plate is not a bearing wall plate, so that the shearing force of the outer wall plate mainly refers to the condition that the outer wall plate is subjected to wind force in a high-rise building, and the outer wall plate is subjected to sun and the like at the same time, if a traditional pasting mode is adopted for the fastening piece, the composite plate is degummed after certain aging, so that the integral fixing structure of the composite plate is damaged, in addition, the truss structure is fixed in a pasting mode, the shearing resistance of the truss structure is not strong, the shearing resistance of the composite plate is weakened after the fastening piece is reacted to the composite plate, and the fastening piece is selected from bolts, so that the integral connecting structure of the composite plate is stable, and the shearing resistance of the truss structure is enhanced under the effect of screw connection and fixation.
As a further description of the above technical solution, a first through hole is formed at a junction of the first inclined plate and the rectangular frame, a second through hole is formed at a junction of the second inclined plate and the rectangular frame, and a third through hole is formed at a junction of the second inclined plate and the first inclined plate;
the fastener is a screw, the screw is in threaded connection with the first panel and the second panel, and the screw passes through the first through hole or the second through hole or the third through hole.
By adopting the technical scheme, the aim of improving the shock resistance of the composite board can be achieved. Screw and truss structure screw thread fixed connection can improve the holistic stability of truss structure and composite sheet, but in the use of composite sheet as side fascia, still need consider the shock resistance of composite sheet, if the composite sheet does not possess shock resistance, truss structure in the composite sheet is when the composite sheet produces vibrations, truss structure self receives the destruction easily, and then influences the shearing resistance of composite sheet. In order to solve the problem, in the application, screws penetrate through the truss structure instead of being in threaded connection with the truss structure, and the truss structure is fixed under the clamping action of the first panel and the second panel, so that the first inclined plate, the second inclined plate and the rectangular frame in the truss structure have a certain activity allowance, and the anti-seismic purpose is achieved.
The second aspect.
The application provides an external wall panel, which comprises a plurality of composite boards, wherein the composite boards are the composite boards in the first aspect, and at least one cavity is formed among the composite boards in parallel;
at least one connecting piece, one connecting piece is arranged in the cavity formed by two adjacent composite boards and fixedly connected through the fastener;
at least one concrete embedded structure, one concrete embedded structure is filled in one cavity.
By adopting the technical scheme, the purposes of enhancing the strength of the external wall panel and endowing the external wall panel with multiple functions can be achieved. Because the external wall panel is formed by a plurality of composite boards, the composite boards can be selected to have certain performance according to building requirements when being selected, and when the panels in a plurality of composite boards in one external wall panel have different functions. At this time, it is equivalent to integrating the panel of a plurality of functions to an external wall panel, and then makes the external wall panel have the multifunctionality (such as waterproof, dampproofing etc.), and through adding concrete thereby can reach the whole intensity of reinforcing external wall panel and strengthen the heat preservation energy-conserving performance of external wall panel.
As a further description of the above technical solution, the connecting piece includes:
the first mounting plate is fixedly connected with one composite plate through the fastener;
the connecting plate is fixedly connected with the first mounting plate;
the second mounting plate is fixedly connected with the other composite plate through the fastening piece, and the second mounting plate is fixedly connected with the connecting plate.
By adopting the technical scheme, the purpose of facilitating the molding of the external wall panel can be achieved. If the connecting piece adopts the mode of long self-tapping screw to directly connect two composite sheets, the following three problems can occur: 1. when two composite boards are connected, a long self-tapping screw is required to pass through the third through hole, the cavity and the third through hole of one composite board in sequence, at the moment, the position accuracy of the third through hole of the two composite boards is required to be ensured, otherwise, the two composite boards cannot be connected by the long self-tapping screw so as to form an external wall board; 2. even if the long self-tapping screw can penetrate through the third through holes of the two composite plates to connect the two composite plates, the long self-tapping screw can incline, obviously, under the condition, the pre-stress applied to the long self-tapping screw can lead the concrete around the long self-tapping screw to crack or the concrete around the long self-tapping screw can not solidify when the concrete is poured; 3. when the external wall panel is used in a building, a plurality of external wall panels are spliced to form a longer external wall panel, because unified standards are required to be formulated for the overall thickness of the external wall panel, the distance between two composite boards cannot be met by adopting the long self-tapping screw even if the two composite boards are connected, and the thickness of the processed external wall panel is inconsistent. In the technical scheme of the application, the connecting path of the screw in the composite board can be reduced by arranging the first mounting plate and the second mounting plate, so that the overall levelness of the screw is ensured, and the stability of the poured concrete is finally achieved; secondly, through setting up the connecting plate thereby can reach and carry out stable connection with two composite sheets to guarantee the interval between two composite sheets, satisfy the construction use of follow-up side fascia.
As a further description of the above technical solution, one free end of the external wall panel is provided with a socket, and the other free end of the external wall panel is provided with an interface which is mutually matched with the socket.
By adopting the technical scheme, the purpose of convenient transportation and installation can be achieved. In the building construction's in-process, to the side fascia that the great room of indoor area used, the length of side fascia is generally longer, and considers transportation and installation's convenience, needs to restrict the length of side fascia, sets up socket and interface through the both ends of side fascia to thereby can realize assembling between two side fascia and satisfy the building demand and the convenient transportation of long side fascia.

Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
In a first aspect, the present application provides a composite panel
Example 1
Referring to fig. 1, the method includes: a first panel 11, a second panel 12, a truss structure 14, and a plurality of fasteners 15, wherein:
referring to fig. 1, a first panel 11, in this embodiment, the first panel 11 may be a decorative panel (the decorative panel has a certain function, such as a waterproof function or a moistureproof function).
Referring to fig. 1, the second panel 12 and the first panel 11 are disposed parallel to each other and formed with a gap 13, wherein the second panel 12 may be selected from plywood (the plywood has a certain function such as a waterproof function or a moisture-proof function, but the functions between the first panel 11 and the second panel 12 are not overlapped, thereby enabling the composite panel 1 to integrate the performance characteristics of the first panel 11 and the second panel 12), and furthermore, the shape and size between the second panel 12 and the first panel 11 are the same.
Referring to fig. 1 and 2, truss structure 14 is shown to enhance shear strength between first panel 11 and second panel 12. Includes a rectangular frame 141, a first inclined plate 142, and a second inclined plate 143. In order to enhance the overall shearing strength of the first panel 11 and the second panel 12, the outer contour shape of the rectangular frame 141 is designed to be the same as the outer contour shape of the first panel 11 and the second panel 12, so that the first panel 11 and the second panel 12 can be completely covered by the rectangular frame 141 to enhance the overall shearing strength of the first panel 11 and the second panel 12. In addition, in order to make the overall structure of the truss structure 14 relatively stable, the first inclined plates 142 and the second inclined plates 143 are disposed along the diagonal lines of the rectangular frame 141 in a crossing manner, so that the rectangular frame 141 can form four triangles, and the triangular shape structure is relatively stable, so that the stability of the overall structure of the truss structure 14 itself can be increased. The first panel 11 and the second panel 12 are fully covered in consideration of the rectangular frame 141. In this way, the shear strength between the first panel 11 and the second panel 12 can be enhanced.
Referring to fig. 1 and 2, a plurality of fasteners 15 are used to fixedly attach the first panel 11, the second panel 12, and the truss structure 14. In this embodiment a plurality of screws are used for the fastener 15. Wherein, two first through holes 1421 are formed at the junction of the first inclined plate 142 and the rectangular frame 141, two second through holes 1431 are formed at the junction of the second inclined plate 143 and the rectangular frame 141, and a third through hole 1432 is formed at the junction of the first inclined plate 142 and the second inclined plate 143. The front-rear positions of the first inclined plate 142 and the second inclined plate 143 with respect to the rectangular frame 141 can be set arbitrarily. One screw is sequentially connected in a threaded manner and penetrates through the first panel 11, the first through hole 1421 and the second panel 12, so that the first panel 11, the truss structure 14 and the second panel 12 are fixedly connected, and the other 4 screws are correspondingly connected according to the method, so that the fixing of the first panel 11, the truss structure 14 and the second panel 12 is realized.
The working mode of the application is described as follows:
the overall stability of the first panel 11 and the second panel 12 can be improved by arranging the truss structure 14, the performance advantages of the first panel 11 and the second panel 12 can be integrated by adopting panels with different performances for the first panel 11 and the second panel 12, and the composite board 1 is more durable by adopting screws to strengthen the connection strength of the first panel 11, the truss structure 14 and the second panel 12.
In addition, it should be noted that the thickness of truss structure 14 is relatively thin, and in the course of actual use, the thickness is selected to be 1mm, so that it can be ensured that first panel 11 and second panel 12 are macroscopically free of gap 13, and although the shearing resistance of first panel 11 and second panel 12 is not very strong due to relatively thin truss structure 14, because composite panel 1 of the present application is an upstream material for an outer wall panel, which does not play a load-bearing role in a wall building, and the shearing force of the outer wall panel is mainly due to high-rise wind force, truss structure 14 of 1mm is designed to sufficiently satisfy the shearing resistance requirement of the outer wall panel in daily high-rise building.
Example 2:
the present application provides a composite board 1, which is different from embodiment 1 in that: the screws are connected differently to the truss structure 14. The remainder was identical to example 1.
In this embodiment: screws pass through the truss structure 14 without being screwed to the truss structure 14, and the truss structure 14 is fastened by clamping the first panel 11 and the second panel 12.
The working mode of the application is described as follows:
the screw and truss structure 14 are fixedly connected by screw, so that the stability of the truss structure 14 and the whole composite board 1 can be improved, however, in the use process of the composite board 1 as an external wall board, the shock resistance of the composite board 1 needs to be considered, if the composite board 1 does not have the shock resistance, the truss structure 14 in the composite board 1 is easily damaged by itself when the composite board 1 vibrates, and the shearing resistance of the composite board 1 is further affected. In the present application, the truss structure 14 is fixed under the clamping action of the first panel 11 and the second panel 12 by passing the screws through the truss structure 14 instead of being screwed with the truss structure 14, so that the first inclined plate 142, the second inclined plate 143 and the rectangular frame 141 in the truss structure 14 have a certain activity margin, thereby achieving the purpose of shock resistance. Therefore, the second embodiment is preferable during actual use.
Second aspect

For the convenience of understanding the composite board 1 here, two connectors 3 are adopted, and one concrete embedded structure 4 is adopted. The remaining deformed structures of the external wall panel can be repeatedly arranged by the following method.
Referring to fig. 1, a composite board 1 is shown in fig. 1, and is the composite board 1 in embodiment 1 or embodiment 2, wherein the composite board 1 has certain functions of shearing resistance, moisture resistance, water resistance and the like, and referring to fig. 3, two composite boards 1 are arranged in parallel to form a cavity 2.
