[0030] The technical solutions of the present application are described in further detail below with reference to the accompanying drawings and examples.

[0031] It should be noted that the present application includes five aspects: The first aspect is a corner beam formwork block.

[0032] The second aspect is a cross beam formwork block matched with the first aspect.

[0033] The third aspect is a T-beam formwork block matched with the second aspect.

[0034] The fourth aspect is an outer beam comprising a plurality of the first aspect corner beam formwork blocks, the second aspect cross beam formwork blocks, and the third aspect T-beam formwork blocks.

[0035] The fifth aspect is an outer beam construction method.

[0036] The five aspects are described in detail below.

[0037] The first aspect, the present application provides a corner beam formwork block 11, Figure 1 A corner beam formwork block structure diagram provided by an embodiment of the present application, Figure 2 A corner beam formwork block top view provided by an embodiment of the present application, Figure 3 A corner beam formwork block side view provided by an embodiment of the present application, in combination with Figures 1 to 3 As shown, the corner beam formwork block 11 comprises a corner beam outer decorative layer 111, a corner beam thermal insulation layer 112, and a corner beam inner structural layer 113, which are introduced below.

[0038] The corner beam outer decorative layer 111 is located at the outermost layer and is realized by using decorative materials, which can be a UHPC facing board.

[0039] The corner beam thermal insulation layer 112 is closely attached to the inner side of the corner beam outer decorative layer and is used to realize heat and sound insulation, which can be an aerogel coating, can realize adhesion with the corner beam outer decorative layer 111 and the corner beam inner structural layer 113, and has good sound insulation and heat insulation effects.

[0040] The inner structure layer 113 of the corner beam, which can be a high-performance prefabricated concrete component such as fiber-reinforced concrete (FRC), ultra-high-performance concrete (UHPC), or high-performance durable concrete (HDC), is connected to the inner side of the corner beam insulation layer 112 through the corner beam connecting part 114, which is made of the same material as the corner beam insulation layer 112 and is integrally connected. The corner beam insulation layer 113, the corner beam connecting part 114, and the corner beam insulation layer 112 form a longitudinal gap 119 and a transverse gap 1190 of the corner beam, which are used to place the reinforcing mesh and subsequent grouting. The outer side of the corner beam connecting part has a semirecessed gap 115, which can be a semicircular structure and forms a circular structure with the semirecessed gap of other formwork blocks for subsequent grouting. To achieve the combination of two corner beam formwork blocks 11, the outer end of the corner beam outer decorative layer 111 is a 45-degree bevel, which is used to splice the outer end of the other corner beam outer decorative layer 111 at a right angle. The outer end of the corner beam insulation layer 112 is a 45-degree bevel, which is used to splice the outer end of the other corner beam insulation layer 112 at a right angle. The outer end of the corner beam inner structure layer 113 is a 45-degree bevel, which is used to splice the outer end of the other corner beam inner structure layer 113 at a right angle. Thus, the two longitudinal gaps 119 form an internal corner beam cavity 110, as shown in Figure 17 The transverse gap 1190 is connected, which is used to place the reinforcing mesh and subsequent grouting.

[0041] In some preferred embodiments, the two corner beam formwork blocks 11 spliced at a right angle are connected by mortise and tenon joints at the external corner splicing part, achieving the interlocking of the two corner beam formwork blocks 11. At the internal corner splicing part, a bolt and a corner connecting piece are used for fixation. Specifically, the corner beam insulation layer 113 is provided with a screw hole matched with the bolt and a groove matched with the corner connecting piece. The corner connecting piece is fixed in the groove, and then fixed by the bolt and the screw hole, thereby achieving the fixation at the internal corner. The corner connecting piece can be an embedded dumbbell-shaped connecting piece.

[0042] In other preferred embodiments, the two corner beam formwork blocks 11 spliced at a right angle are fixed by a first closing strip at the internal corner splicing part. The first closing strip includes two straightly connected closing areas, which accommodate the two first corner column inner structure layers spliced respectively.

[0043] It can be understood that the corner beam formwork block 11 needs to be inserted with a wall formwork block below. Therefore, to achieve the up-down insertion with other wall formwork blocks, the corner beam outer decorative layer 111 and the corner beam inner structure layer 113 are longitudinally staggered with the corner beam insulation layer 112, thereby forming a corner beam formwork longitudinal protrusion 116 at the upper part and a corner beam formwork longitudinal recess 117 at the lower part.

[0044] In some preferred embodiments, the side surface of the corner beam formwork block 11 needs to be inserted with the external beam formwork block 12, so that in order to realize the insertion with the external beam formwork block, the corner beam insulation layer 112 and the corner beam connecting part 114 are arranged in a recessed manner with the corner beam outer decorative layer 111 and the corner beam inner structural layer 113, so as to form a corner beam formwork transverse recess 118 on the outer side, and it needs to be noted that the structure of the external beam formwork block 12 is introduced in the second aspect below.

[0045] Specifically, when the corner beam formwork block 11 is inserted with the external beam formwork block 12, the corner beam formwork transverse recess 118 is inserted and connected with the external beam formwork block protrusion 1280 of the external beam formwork block 12, so that the corner beam half recess 115 and the beam half recess 125 of the external beam formwork block 12 form a combined hole for subsequent grouting, and the corner beam transverse notch 1190 and the transverse notch 1290 of the external beam formwork block 12 are in communication for placing a steel mesh frame and subsequent grouting.

[0046] Secondly, the beam formwork block 12 cooperates with the first aspect, Figure 6 A schematic diagram of a beam formwork block structure is provided for the embodiment of the present application, Figure 7 A top view of a beam formwork block is provided for the embodiment of the present application, Figure 8 A side view of a beam formwork block is provided for the embodiment of the present application, in combination Figures 6 to 8 As shown, the beam formwork block 12 includes a beam outer decorative layer 121, a beam insulation layer 122, and a beam inner structural layer 123, and the layer structure thereof is introduced below.

[0047] The beam outer decorative layer 121 is located at the outermost layer and is realized by using a decorative material, and specifically can be a UHPC facing plate.

[0048] The beam insulation layer 122 is closely attached to the inner side of the beam outer decorative layer and is used to realize heat and sound insulation, and specifically can be an aerogel coating, which can realize adhesion with the beam outer decorative layer 121 and the beam inner structural layer 123 and has good sound insulation and heat insulation effects.

[0049] The inner structure layer 123 of the cross beam, which can be a high-performance prefabricated concrete component such as fiber-reinforced concrete (FRC), ultra-high-performance concrete (UHPC), or high-performance durable concrete (HDC), is connected to the inner side of the cross beam insulation layer through the cross beam connecting part 124, which is made of the same material as the cross beam inner structure layer 123 and is integrally connected. The cross beam inner structure layer 123, the cross beam connecting part 124, and the cross beam insulation layer 122 form a cross beam transverse gap 1290 for placing a steel mesh frame and subsequent grouting. The central part of the cross beam connecting part 124 has a cross beam longitudinal hole 129 for subsequent grouting, and the outer side of both ends of the cross beam connecting part has a cross beam semi-recess 125, which can be a semicircular structure, and forms a circular structure with the semi-recess of other formwork blocks for subsequent grouting.

[0050] To improve the stability between the cross beam inner structure layer 123 and the cross beam insulation layer 122 inside the cross beam formwork block 12, steel joints are pre-embedded in the cross beam inner structure layer 123 and the cross beam insulation layer 122. The pre-embedded steel joints of the cross beam inner structure layer 123 and the cross beam insulation layer 122 are welded with short steel bars to connect and fix the cross beam inner structure layer 123 and the cross beam insulation layer 122, as shown in Figure 9 and 12 . To realize the combination between two cross beam formwork blocks 12, the cross beam outer decorative layer 121 and the cross beam inner structure layer 123 are staggered with the cross beam insulation layer 122 and the cross beam connecting part 124, forming a cross beam formwork transverse recess 128 on one side and a cross beam formwork transverse protrusion 1280 on the other side. The cross beam formwork transverse recess 128 is inserted into the cross beam formwork transverse protrusion 1280 of another cross beam formwork block, and the cross beam semi-recess 125 forms a combined hole with the cross beam semi-recess 125 of the external cross beam formwork block 12 for subsequent grouting.

[0051] In some preferred embodiments, as shown in Figure 11 , two cross beam formwork blocks 12 spliced into a straight angle are fixed with bolts and flat connectors. Specifically, the cross beam inner structure layer 123 is provided with screw holes matched with the bolts and grooves matched with the corner connectors, the corner connectors are fixed in the grooves, and the bolts and screw holes are fixed, thereby realizing the fixation. The corner connector can be an embedded dumbbell-shaped connector.

[0052] It can be understood that the cross beam formwork block 12 needs to be inserted into the wall formwork block below. Therefore, to realize the upward and downward insertion with other wall formwork blocks, the cross beam outer decorative layer 121 and the cross beam inner structure layer 123 are longitudinally staggered with the cross beam insulation layer 122, forming a cross beam formwork longitudinal protrusion 126 at the upper part and a cross beam formwork longitudinal recess 127 at the lower part.

[0053] In some preferred embodiments, the side of the crossbeam formwork block 12 that is inserted needs to be connected to the external corner beam formwork block 11. Therefore, in order to achieve the connection with the external corner beam formwork block 11, the transverse protrusion 1280 of the crossbeam formwork is inserted into the transverse recess 118 of the corner beam formwork of the external corner beam formwork block 11. Thus, the transverse recess 125 of the crossbeam and the transverse recess 115 of the corner beam of the external corner beam formwork block 11 form a combined hole, and the transverse notch 1290 of the crossbeam is connected to the transverse notch 1190 of the crossbeam of the external corner beam formwork block 11, for placing the steel mesh and subsequent grouting.

[0054] Thirdly, regarding the T-beam formwork block 13, which cooperates with the second aspect. Figure 12 This is a schematic diagram of a T-beam formwork block structure provided in an embodiment of the present invention. Figure 13 This is a top view of a T-beam formwork block provided in an embodiment of the present invention. Figure 14 A side view of a T-beam formwork block provided in an embodiment of the present invention, combined with Figures 12 to 14 As shown, the T-beam formwork block 13 includes an outer decorative layer 131, an inner insulation layer 132, and an inner structural layer 133. The structure of these layers is described below.

[0055] The T-beam exterior decorative layer 131, located on the outermost layer, is achieved using decorative materials, specifically UHPC surface panels.

[0056] The T-beam insulation layer 132 is tightly attached to the inner side of the T-beam outer decorative layer to achieve heat insulation and sound insulation. Specifically, it can be an aerogel coating that can be bonded to the T-beam outer decorative layer 131 and the T-beam inner structural layer 133, and has good sound insulation, heat insulation and thermal insulation effects.

[0057] The inner structural layer 133 of the T-beam can be a high-performance precast concrete component, such as fiber-reinforced concrete (FRC), ultra-high performance concrete (UHPC), or high-performance durable concrete (HDC). It is connected to the inner side of the T-beam insulation layer 132 through the T-beam connection part 134. The T-beam connection part 134 and the T-beam insulation layer 132 are made of the same material and are integrally connected. The corner beam insulation layer 113, the T-beam connection part 134 and the T-beam insulation layer 132 form a longitudinal notch 139 and a transverse notch 1390 for placing the steel mesh and subsequent grouting. The outer side of the T-beam connection part has a T-beam semi-recessed notch 135, which can be a semi-circular structure. It forms a circular structure with the semi-recessed notches of other formwork blocks for subsequent grouting. Two T-shaped beam formwork blocks 13 and one external inner beam transition module 15 can form a T-shaped beam structure. When the T-shaped beam structure is spliced, in order to realize the combination between the two T-shaped beam formwork blocks 13, the outer end of the T-shaped beam outer decorative layer 131 is longitudinally flat, used for splicing with the outer end of other T-shaped beam outer decorative layers 131 as a straight angle; the outer end of the T-shaped beam insulation layer 132 is longitudinally flat, used for splicing with the outer end of other T-shaped beam insulation layers 132 as a straight angle; further, as shown in Figure 15 and Figure 16 , the outer end of the T-shaped beam inner structure layer 133 is longitudinally at a 45-degree angle, used for splicing with the first structure layer 151 of the external inner beam transition module 15 as a right angle; at the same time, the outer end of the other T-shaped beam inner structure layer 133 is longitudinally at an angle, used for splicing with the second structure layer 153 of the external inner beam transition module 15 as a right angle, so as to form a T-shaped beam structure, and the two T-shaped beam transverse notches 1390 and the inner beam transition beam transverse notch 1590 of the external inner beam transition module 15 are in communication, used for placing a steel mesh frame and subsequent grouting, two T-shaped beam formwork blocks 13 and one external inner beam transition module 15 can form a T-shaped beam structure, as shown in Figure 17 .

[0058] It should be noted that, as shown in Figure 15 and Figure 16 , the above-mentioned inner beam transition formwork block 15 includes an inner beam transition first structure layer 151, an inner beam transition second structure layer 153, and an inner beam transition connecting part 154, and the layer structure thereof will be introduced below. The inner beam transition first structure layer 151 is arranged on the outer side. The inner beam transition second structure layer 153 is arranged on the inner side, connected with the inner beam transition first structure layer 151 through the inner beam transition connecting part 154, forming an inner beam transition longitudinal notch 159 and an inner beam transition transverse notch 1590, used for placing a steel mesh frame and subsequent grouting, and the outer side of the inner beam transition connecting part has an inner beam transition semi-recess 155, which can be a semicircular structure, and forms a circular structure with the semi-recess of other formwork blocks, used for subsequent grouting. The outer end of the inner beam transition first structure layer 151 is longitudinally at a 45-degree angle, and the outer end of the inner beam transition second structure layer 153 is longitudinally at a 45-degree angle, matched with the T-shaped beam formwork block 13.

[0059] It can be understood that the lower part of the T-shaped beam formwork block 13 needs to be inserted into a column block, and thus in order to realize the up-down insertion with other column blocks, the T-shaped beam outer decorative layer 131 and the T-shaped beam inner structure layer 133 are longitudinally staggered with the T-shaped beam insulation layer 132, so as to form a T-shaped beam formwork longitudinal protrusion 136 on the upper part and a T-shaped beam formwork longitudinal recess 137 on the lower part.

[0060] It is understood that the side of the T-beam formwork block 13 can be inserted into the crossbeam formwork block 12 mentioned above. In order to achieve the insertion of the two, the T-beam insulation layer 112 and the T-beam connection part 134 are provided between the T-beam outer decorative layer 131 and the T-beam inner structural layer 133, thereby forming a T-beam formwork transverse protrusion 138 on the outside. Furthermore, the T-beam formwork transverse protrusion 138 is inserted into the crossbeam formwork transverse recess 128 of the outer crossbeam formwork block 12, thereby forming a combined hole with the T-beam semi-recess 135 and the crossbeam semi-recess 125 of the outer crossbeam formwork block 12, and the T-beam transverse notch 1390 is connected with the transverse notch 1290 of the outer crossbeam formwork block 12 for placing the steel mesh and subsequent grouting.

[0061] Preferably, the T-beam outer decorative layer 131 of the T-beam formwork block 13 and the outer beam outer decorative layer 121 of the outer beam formwork block 12 are fixed together by bolts and flat connectors. Specifically, the T-beam outer decorative layer 131 and the outer beam outer decorative layer 121 are provided with screw holes that match the bolts and grooves that match the flat connectors. The flat connectors are fixed in the grooves and then fixed by bolts and screw holes, thereby achieving fixation. The flat connectors here can be embedded dumbbell-shaped connectors.

[0062] Fourthly, such as Figure 17 As shown, the outer beam and inner beam include multiple corner beam formwork blocks 11, beam formwork blocks 12, T-beam formwork blocks 13, secondary beam formwork blocks 14, and secondary beam transition formwork blocks 15. This application provides an outer beam including multiple of the above-mentioned first-sided corner beam formwork blocks 11, second-sided transverse beam formwork blocks 12, and third-sided T-beam formwork blocks 13. The structures of the three are the same as those mentioned above. Their structures are briefly described below.

[0063] The corner beam formwork block 11 includes an outer decorative layer 111, a corner beam insulation layer 112, and an inner structural layer 113. The structure of each layer is described below.

[0064] The corner beam outer decorative layer 111 is located at the outermost layer and is implemented by using a decorative material, and can be a UHPC facing plate. The corner beam insulation layer 112 is closely attached to the inner side of the corner beam outer decorative layer, and is used to achieve heat and sound insulation. Specifically, it can be an aerogel coating, which can be glued with the corner beam outer decorative layer 111 and the corner beam inner structural layer 113, and has good sound insulation and heat insulation effects. The corner beam inner structural layer 113 can be a high-performance prefabricated concrete member, such as fiber reinforced concrete (FRC), ultra-high performance concrete (UHPC), or high-performance durable concrete (HDC). The bottom is connected to the inner side of the corner beam insulation layer 112 through the corner beam connecting part 114. The corner beam connecting part 114 and the corner beam insulation layer 112 are made of the same material and are integrally connected. The corner beam insulation layer 113, the corner beam connecting part 114, and the corner beam insulation layer 112 form a corner beam longitudinal gap 119 and a corner beam transverse gap 1190, which are used to place a steel mesh frame and subsequent grouting. The outer side of the corner beam connecting part has a corner beam semi-recess 115, which can be a semicircular structure and forms a circular structure with the semi-recess of other formwork blocks, which is used for subsequent grouting. In order to realize the combination of two corner beam formwork blocks 11, the outer end of the corner beam outer decorative layer 111 is a 45-degree bevel, which is used to splice with the outer end of the other corner beam outer decorative layer 111 to form a right angle. The outer end of the corner beam insulation layer 112 is a 45-degree bevel, which is used to splice with the outer end of the other corner beam insulation layer 112 to form a right angle. The outer end of the corner beam inner structural layer 113 is a 45-degree bevel, which is used to splice with the outer end of the other corner beam inner structural layer 113 to form a right angle. Thus, the two corner beam longitudinal gaps 119 form a corner beam cavity 110 inside, as shown in Figure 17 The corner beam transverse gap 1190 is connected, which is used to place a steel mesh frame and subsequent grouting.

[0065] In some preferred embodiments, the two corner beam formwork blocks 11 spliced into a right angle are connected by a mortise and tenon joint at the external corner splicing part, realizing the interlocking of the two corner beam formwork blocks 11. At the internal corner splicing part, a bolt and a corner connecting piece are used for fixing. Specifically, the corner beam insulation layer 113 is provided with a screw hole matched with the bolt and a groove matched with the corner connecting piece. The corner connecting piece is fixed in the groove, and then fixed by the bolt and the screw hole, thereby realizing the fixing of the internal corner. The corner connecting piece can be an embedded dumbbell-shaped connecting piece.

[0066] In other preferred embodiments, the two corner beam formwork blocks 11 spliced into a right angle are fixed by a first closing strip at the internal corner splicing part. The first closing strip includes two straightly connected closing areas, and the two closing areas accommodate the two first corner column inner structural layers spliced respectively.

[0067] It can be understood that the wall formwork block needs to be inserted under the corner beam formwork block 11, so that the outer decorative layer 111 and the inner structural layer 113 of the corner beam are longitudinally staggered with the corner beam insulation layer 112, thereby forming a longitudinal protrusion 116 of the corner beam formwork on the upper part and a longitudinal recess 117 of the corner beam formwork on the lower part.

[0068] In some preferred embodiments, the side of the corner beam formwork block 11 needs to be inserted with the external beam formwork block 12, so that the corner beam insulation layer 112 and the corner beam connecting part 114 are recessed with the corner beam outer decorative layer 111 and the corner beam inner structural layer 113, thereby forming a transverse recess 118 of the corner beam formwork on the outer side. It should be noted that the structure of the external beam formwork block 12 is introduced in the second aspect below.

[0069] Specifically, when the corner beam formwork block 11 is inserted with the external beam formwork block 12, the transverse recess 118 of the corner beam formwork is inserted and connected with the external beam formwork protrusion 1280 of the external beam formwork block 12, so that the corner beam half recess 115 and the half recess 125 of the external beam formwork block 12 form a combined hole for subsequent grouting, and the corner beam transverse recess 1190 and the transverse recess 1290 of the external beam formwork block 12 are in communication for placing the steel mesh frame and subsequent grouting.

[0070] The beam formwork block 12 includes a beam outer decorative layer 121, a beam insulation layer 122, and a beam inner structural layer 123, the layer structure of which is introduced below.

[0071] The beam outer decorative layer 121 is located in the outermost layer and is realized by using decorative materials, which can be a UHPC facing board. The beam insulation layer 122 is closely attached to the inner side of the beam outer decorative layer and is used to achieve heat and sound insulation, which can be an aerogel coating that can realize adhesion with the beam outer decorative layer 121 and the beam inner structural layer 123 and has good sound insulation and heat insulation effects. The beam inner structural layer 123 can be a high-performance prefabricated concrete member, such as fiber-reinforced concrete (FRC), ultra-high performance concrete (UHPC), or high-performance durable concrete (HDC), which is connected to the inner side of the beam insulation layer through the beam connecting part 124. The beam connecting part 124 and the beam inner structural layer 123 are of the same material and are integrally connected, and the beam inner structural layer 123, the beam connecting part 124, and the beam insulation layer 122 form a beam transverse recess 1290 for placing the steel mesh frame and subsequent grouting. The beam connecting part 124 has a beam longitudinal hole 129 in the center for subsequent grouting, and the outer side of both ends of the beam connecting part has a beam half recess 125, which can be a semicircular structure and forms a circular structure with the half recess of other formwork blocks for subsequent grouting.

[0072] In order to improve the stability between the inner structural layer 123 and the thermal insulation layer 122 of the beam formwork block 12, the embedded steel joint 40 is arranged in the inner structural layer 123 and the thermal insulation layer 122, the embedded steel joint 40 in the inner structural layer 123 and the embedded steel joint in the thermal insulation layer 122 are welded by short steel, so as to connect and fix the inner structural layer 123 and the thermal insulation layer 122, which is specifically shown in Figure 9 and 12 . In order to realize the combination between two beam formwork blocks 12, the outer decorative layer 121 and the inner structural layer 123 are staggered with the thermal insulation layer 122 and the beam connecting part 124, so as to form a beam formwork transverse recess 128 on one side and a beam formwork transverse protrusion 1280 on the other side; the beam formwork transverse recess 128 is inserted with the beam formwork transverse protrusion 1280 of the other beam formwork block, so as to form a combination hole by the beam half recess 125 and the beam half recess 125 of the external beam formwork block 12, which is used for subsequent grouting.

[0073] In some preferred embodiments, as shown in Figure 11 , the two beam formwork blocks 12 spliced into a flat angle are fixed by bolts and flat connectors, specifically, the inner structural layer 123 is provided with screw holes matched with the bolts and grooves matched with the corner connectors, the corner connectors are fixed in the grooves, and then fixed by the bolts and the screw holes, so as to realize the fixation, and the corner connector here can be an embedded dumbbell-shaped connector.

[0074] It can be understood that the beam formwork block 12 needs to be inserted with a wall formwork block below, so as to realize the upward and downward insertion with other wall formwork blocks, the outer decorative layer 121 and the inner structural layer 123 are arranged longitudinally staggered with the thermal insulation layer 122, so as to form a beam formwork longitudinal protrusion 126 on the upper part and a beam formwork longitudinal recess 127 on the lower part.

[0075] In some preferred embodiments, the side of the beam formwork block 12 needs to be inserted with an external corner beam formwork block 11, so as to realize the insertion with the external corner beam formwork block 11, the beam formwork transverse protrusion 1280 is inserted with the corner beam formwork transverse recess 118 of the external corner beam formwork block 11, so as to form a combination hole by the beam half recess 125 and the corner beam half recess 115 of the external corner beam formwork block 11, and the beam transverse notch 1290 is communicated with the beam transverse notch 1190 of the external corner beam formwork block 11, which is used for placing a steel mesh frame and subsequent grouting.

[0076] The T-shaped beam formwork block 13 comprises a T-shaped beam outer decorative layer 131, a T-shaped beam thermal insulation layer 132, and a T-shaped beam inner structural layer 133. The layer structure thereof is introduced as follows.

[0077] The T-shaped beam outer decorative layer 131 is located at the outermost layer and is implemented by using a decorative material, and can be a UHPC facing board. The T-shaped beam thermal insulation layer 132 is closely attached to the inner side of the T-shaped beam outer decorative layer and is used to achieve heat and sound insulation, and can be an aerogel coating, which can be glued with the T-shaped beam outer decorative layer 131 and the T-shaped beam inner structural layer 133 and has good sound insulation and heat insulation effects. The T-shaped beam inner structural layer 133 can be a high-performance prefabricated concrete member, such as fiber reinforced concrete (FRC), ultra-high performance concrete (UHPC), or high-performance durable concrete (HDC), and is connected to the inner side of the T-shaped beam thermal insulation layer 132 through a T-shaped beam connecting part 134. The T-shaped beam connecting part 134 and the T-shaped beam thermal insulation layer 132 are integrally connected and are made of the same material. The T-shaped beam thermal insulation layer 113, the T-shaped beam connecting part 134, and the T-shaped beam thermal insulation layer 132 form a T-shaped beam longitudinal gap 139 and a T-shaped beam transverse gap 1390, which are used to place a steel mesh frame and subsequent grouting. The outer side of the T-shaped beam connecting part has a T-shaped beam semi-recess 135, which can be a semicircular structure and forms a circular structure with the semi-recess of other formwork blocks, which is used for subsequent grouting. Two T-shaped beam formwork blocks 13 and one external inner beam transition module 15 can form a T-shaped beam structure. In order to realize the combination between the two T-shaped beam formwork blocks 13, the outer end of the T-shaped beam outer decorative layer 131 is longitudinally flat, which is used to splice with the outer end of other T-shaped beam outer decorative layers 131 to form a straight angle. The outer end of the T-shaped beam thermal insulation layer 132 is longitudinally flat, which is used to splice with the outer end of other T-shaped beam thermal insulation layers 132 to form a straight angle. Further, as shown in Figure 15 and Figure 16 , the outer end of the T-shaped beam inner structural layer 133 is longitudinally at an angle of 45 degrees, which is used to splice with the outer end of the first structural layer 151 of the external inner beam transition module 15 to form a right angle. At the same time, the outer end of the other T-shaped beam inner structural layer 133 is longitudinally at an angle, which is used to splice with the outer end of the second structural layer 153 of the external inner beam transition module 15 to form a right angle, thereby forming a T-shaped beam structure, and the two T-shaped beam transverse gaps 1390 and the inner beam transition beam transverse gap 1590 of the external inner beam transition module 15 are connected, which are used to place a steel mesh frame and subsequent grouting. Two T-shaped beam formwork blocks 13 and one external inner beam transition module 15 can form a T-shaped beam structure, as shown in Figure 17 .

[0078] It should be noted that the inner beam transition formwork block 15 described above includes an inner beam transition first structural layer 151, an inner beam transition second structural layer 153, and an inner beam transition connecting portion 154, and the layer structure thereof will be introduced below. The inner beam transition first structural layer 151 is arranged on the outer side. The inner beam transition second structural layer 153 is arranged on the inner side and is connected with the inner beam transition first structural layer 151 through the inner beam transition connecting portion 154, forming an inner beam transition longitudinal notch 159 and an inner beam transition transverse notch 1590 for placing a steel mesh frame and subsequent grouting, and the outer side of the inner beam transition connecting portion has an inner beam transition semi-recessed notch 155, which can be a semicircular structure, and forms a circular structure with the semi-recessed notch of other formwork blocks for subsequent grouting. The outer end of the inner beam transition first structural layer 151 is a 45-degree inclined surface in the longitudinal direction, and the outer end of the inner beam transition second structural layer 153 is a 45-degree inclined surface in the longitudinal direction, which is matched with the T-beam formwork block 13.

[0079] It can be understood that the lower side of the T-beam formwork block 13 needs to be inserted into the column block, and thus in order to realize the upper and lower insertion with other column blocks, the T-beam outer decorative layer 131 and the T-beam inner structural layer 133 are arranged longitudinally staggered with the T-beam thermal insulation layer 132, so as to form a T-beam formwork longitudinal protrusion 136 on the upper part and a T-beam formwork longitudinal recess 137 on the lower part.

[0080] It can be understood that the side surface of the T-beam formwork block 13 can be inserted into the transverse beam formwork block 12 of the second aspect described above, and thus in order to realize the insertion of the two, the T-beam thermal insulation layer 112 and the T-beam connecting portion 134 are protrudingly arranged between the T-beam outer decorative layer 131 and the T-beam inner structural layer 133, so as to form a T-beam formwork transverse protrusion 138 on the outer side; further, the T-beam formwork transverse protrusion 138 is inserted and connected with the transverse beam formwork transverse recess 128 of the external transverse beam formwork block 12, so that the T-beam semi-recessed notch 135 and the transverse beam semi-recessed notch 125 of the external transverse beam formwork block 12 form a combined hole, and the T-beam transverse notch 1390 and the transverse notch 1290 of the external transverse beam formwork block 12 are in communication, which are used for placing a steel mesh frame and subsequent grouting.

[0081] Preferably, the T-beam outer decorative layer 131 of the T-beam formwork block 13 and the transverse beam outer decorative layer 121 of the external transverse beam formwork block 12 are fixed through bolts and planar connecting pieces, and specifically, the T-beam outer decorative layer 131 and the transverse beam outer decorative layer 121 are provided with screw holes matched with the bolts and grooves matched with the planar connecting pieces, the planar connecting pieces are fixed in the grooves, and the fixing is realized through the bolts and the screw holes. The planar connecting piece here can be an embedded dumbbell-shaped connecting piece.

[0082] The outer beam cavity is formed by the mutually connected corner beam transverse gap 1190, the transverse beam transverse gap 1290 and the T-shaped beam transverse gap 1390, and is used for placing a steel bar framework and subsequent grouting.

[0083] In some preferred embodiments, the outer beam further comprises an outer beam steel bar framework, the outer beam cavity is further filled with self-compacting grout through the transverse beam longitudinal hole 129 and the combined hole, and thus the connection strength between the outer beam steel bar framework and the outer beam formwork block is improved.

[0084] In a fifth aspect, the application further provides a construction method based on the outer beam of the fourth aspect, as shown in the following steps. Figure 18 As shown in the following steps: Step 101, formwork setting: setting a support frame, laying beam formwork blocks in the support frame to form a closed loop.

[0085] According to the actual design needs, the support frame is set according to the arrangement of the beam, and permanent support or temporary support can be used. The first aspect corner beam formwork block 11, the second aspect transverse beam formwork block 12 and the third aspect T-shaped beam formwork block 13 are laid in the support frame, and the outer beam with a closed loop structure is formed.

[0086] Step 102, steel bar framework manufacturing and installation: manufacturing and installing a beam steel bar framework according to the shape and size of the secondary structure beam cross section, the beam steel bar framework comprising longitudinal bars and stirrups, and the stirrup encryption area can be set.

[0087] Since the steel bar framework is arranged in the outer beam cavity formed by the plurality of beam formwork blocks, the steel bar framework (which can be prefabricated or field tied) is manufactured according to the shape and size of the secondary structure column cross section in the cavity, and then installed. Further, those skilled in the art can set the stirrup encryption area and encrypt important areas as needed.

[0088] Step 103, secondary pouring: pouring self-compacting concrete into the beam formwork block cavity until the cavity is filled.

[0089] The manufactured steel bar framework is fixed in the beam formwork block cavity, and then self-compacting concrete is poured into the beam formwork block cavity until the cavity is filled, thereby realizing the connection and fixation between the outer beam steel bar framework and the outer beam formwork block.

[0090] In preferred embodiments, the method further comprises: setting a gradient circular arc on the bottom plate of the pre-cambered beam formwork block, so that the bottom of the secondary poured structure beam forms an arc of 1 / 1000-10 / 1000. The pre-cambered beam is described in detail below. Figure 19 A pre-cambered beam explosion schematic diagram is provided for the embodiments of the application,Figure 20 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figure 21 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figure 20 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figure 22 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figure 23 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figure 22 A schematic diagram of a pre-arched beam formwork block structure provided for an embodiment of the present application, Figures 19 to 23 As shown in the drawings, the mechanical properties of the large-span beam component are higher, and therefore the present application also provides a pre-arched beam formwork block 1000, a secondary structure beam reinforcement framework 2000, and a secondary structure pre-arched beam 3000. In order to improve the stress performance of the beam component without increasing or with less increase in the beam cross-sectional height and reinforcement ratio, and to meet the demand for larger-span space construction, based on the previous beam formwork block, by optimizing the formwork block bottom plate, a gradient circular arc bottom plate is arranged along the height direction of the block, so that the secondary structure beam (reinforced concrete main beam, secondary beam) is arched, the adverse deformation is reduced, and the overall stability and safety of the structure are improved.

[0091] The pre-arched beam formwork block corresponds to the corner beam formwork block 11a, the beam formwork block 12a, the T-beam formwork block 13a, the secondary beam formwork block 14a, and the secondary beam transition formwork block 15a of the corresponding beam module block of the previous beam module block, and only the bottom plate structure is different. According to the change of the beam span, a gradient circular arc is arranged on the bottom plate of the pre-arched beam formwork block, so that the bottom of the secondary pouring structure beam forms an arc (h / l) of 1 / 1000-10 / 1000. The pre-arched beam formwork block needs to be assembled in the designed order to ensure the continuity of the circular arc. The formwork blocks can be numbered in advance (for example, sequentially numbered from small to large according to Arabic numerals from the middle to both ends), and assembled according to the number during construction. After sequentially completing the formwork block assembly and the reinforcement framework installation, the secondary pouring of concrete can be performed in the formwork block cavity to form a secondary structure pre-arched beam component. The bottom of the beam component forms an arc according to the arc of the formwork block bottom plate, and the pre-arched effect is achieved.
