DETAILED DESCRIPTION

[0031] The following non-limiting examples are provided to illustrate the present application.

[0032] Example 1

[0033] refer to Figure 1 to Figure 4 As shown, an assembled antique building roof construction structure includes a prefabricated rafter 1, a prefabricated panel 2, a baffle 3, a structural beam 4 and a support system.

[0034] The support system is used to support the precast rafters 1. A number of precast rafters 1 are arranged at intervals on the support system. The precast rafters 1 are arranged in parallel at equal intervals. The precast rafters 1 serve as the foundation and support for casting enclosures in the early stage and form a decorative structure of the roof in the later stage. The precast rafter 1 includes a rafter body 101. The rafter body 101 is provided with a top anchor bar 102 extending to the roof casting area. After the subsequent casting of the roof concrete, the rafter body 101 is connected to the roof casting as a whole through the top anchor bar 102.

[0035] The rafter body 101 is provided with a shoulder step 104, and a prefabricated panel 2 is provided between the shoulder steps 104 of two adjacent rafter bodies 101, that is, the two adjacent rafter bodies 101 on the left and right are used to support the middle prefabricated panel 2, and the horizontal gap between the two rafter bodies 101 is covered. The prefabricated panel 2 is flush with the lower end surface of the roof casting area, and the prefabricated panel 2 serves as the foundation for casting enclosures in the early stage and as part of the roof in the later stage.

[0036] The prefabricated rafter 1 is a reinforced concrete structure, including a rafter body 101, a top anchor bar 102, an end anchor bar 103, a shoulder step 104, a built-in cavity 105 and a plug 106. The rafter body 101 is a rectangular solid concrete material, and a steel skeleton is arranged inside. A top anchor bar 102 extends from the top of the rafter body 101, and the top anchor bar 102 is preferably an L-shaped bending structure. A plurality of top anchor bars 102 are arranged at intervals along the length direction, and are subsequently connected to the roof concrete pouring to ensure good anchoring strength.

[0037] An end anchor 103 extends from the end of the rafter body 101. The end anchor 103 is preferably a small-angle (0-20°) bending structure. Several end anchors 103 are arranged at intervals along the peripheral direction and are subsequently cast and connected with other building bodies. For example, the structural beam casting area of ​​the structural beam 4 is also cast and connected to other building bodies to ensure good connection strength of the rafter body 101.

[0038] The shoulder of the rafter body 101 is provided with a shoulder step 104, which is the left and right corners of the upper cross section of the rafter body 101. The shoulder step 104 is preferably an L-shaped concave corner to facilitate the placement of the prefabricated panel 2 therein. The step height is preferably the same as the thickness of the prefabricated panel 2.

[0039] The rafter body 101 is provided with an internal cavity 105, which is preferably a cylindrical structure with two ends connected, so as to reduce the overall amount of prefabricated rafters 1, optimize costs, and also reduce the overall quality, facilitating construction operations. The end of the internal cavity 105 is provided with a plug 106, which can be a rubber or plastic plug to block the port when the roof is poured to prevent concrete from leaking into the cavity.

[0040] Since the prefabricated rafters 1 are arranged at intervals, there is a horizontal gap between two adjacent prefabricated rafters 1, and the horizontal gap is blocked and closed by the prefabricated panel 2, and the prefabricated panel 2 is preferably a cement board. At the same time, there is a vertical gap between the two prefabricated rafters 1 at both ends, and the vertical gap is blocked and closed by the baffle 3, which is preferably a cement board and is set at the end between the two adjacent rafter bodies 101.

[0041] The support system includes a support frame and a template 5. The support frame can be in the form of a scaffold or the like. The template 5 includes a bottom template 501, a side template 502, and a slope template 503. A flat bottom template 501 is supported on the support frame on the ground, and prefabricated rafters 1 are supported on the bottom template 501. The plane of the bottom template 501 is used to position and lift all prefabricated rafters 1 to ensure that all prefabricated rafters 1 are located on the same plane.

[0042] The bottom formwork 501 is fixedly connected to the side formwork 502, and the side formwork 502 is set at the end between two adjacent rafter bodies 101, that is, the side formwork 502 is not only used for enclosure during the subsequent roof pouring, but also used to block and close the vertical gap between two adjacent prefabricated rafters 1.

[0043] The structural beam 4 includes a beam body 401 made of concrete and a beam reinforcement 402, and the end anchor bar 103 extends to the structural beam casting area of ​​the structural beam 4. The structural beam casting area is cast for the second time while the roof is cast, so as to realize the casting connection between the prefabricated rafter 1 and the structural beam 4. The slope template 503 is extended on the other side of the structural beam 4, and extends from the wall surface of the structural beam 4 upward and then to the outer side of the upper part, forming a casting slope with a slope.

[0044] Example 2

[0045] refer to Figure 1 to Figure 4 As shown, a method for constructing an assembled antique building roof comprises the following steps: First, the size of the antique prefabricated rafter 1 and the prefabricated panel 2 is determined according to the drawing, and the prefabricated rafter 1 and the prefabricated panel 2 are manufactured. The structure of the prefabricated rafter 1 and the prefabricated panel 2 is the same as that of the first embodiment.

[0046] The second step is to set up a support system. The support system includes a support frame and a template 5. The template 5 includes a bottom template 501 and a side template 502. The support frame is first set up, and then the bottom template 501 is laid on the support frame. The bottom template 501 is supported on the support frame on the ground. The bottom template 501 is used to support the prefabricated rafter 1. The bottom template 501 is connected to the side template 502.

[0047] The third step is to draw lines on the bottom template 501 according to the drawing and locate the installation position of the prefabricated rafter 1 on the support system.

[0048] Step 4: According to the positioning line, the prefabricated rafter 1 is installed on the bottom template 501 of the support system, the top anchor bar 102 extends to the roof casting area, and the end anchor bar 103 extends to the structural beam casting area. The two sides of the prefabricated rafter 1 are fixed to the bottom template 501 with steel nails to prevent lateral movement. At the same time, ensure that the side template 502 is located at the end between the two adjacent rafter bodies 101.

[0049] The fifth step is to install the prefabricated panel 2, and cover the shoulder steps 104 of two adjacent rafter bodies 101 to ensure that the prefabricated panel 2 is flush with the lower end surface of the roof casting area. The baffle 3 and the plug 106 are also installed, and the baffle 3 is set at the end between the two adjacent rafter bodies 101, and the plug 106 is plugged at the port of the rafter body 101.

[0050] Finally, the gaps formed by the adjacent structures of the prefabricated rafters 1, the prefabricated panels 2, the baffles 3, the side formwork 502 and the plugs 106 are sealed with cement mortar to prevent leakage.

[0051] Step 6: Tie the steel bars and pour concrete in the roof pouring area.

[0052] The rest is the same as in Example 1.
