Problems solved by technology

Brick tire formwork has been used for more than 30 years in the construction of basement foundations, caps, and ground beams as a sluice for pouring reinforced concrete, and it is still used in most areas, but in my country The southern region, such as the basement project that the inventor has participated in construction: Shanghai Pudong, Zhejiang Wenzhou, Guangdong Guangzhou, Shenzhen, Foshan, Zhongshan, Zhuhai and other coastal areas, when every excavation reaches about 2 meters below ±0.00, it will Water seepage, mud, quicksand and other adverse phenomena appear, and it is easy to cause landslides, which have great potential safety hazards. In this special natural environment, the method of "brick tire mold" takes a long time to construct and has great potential safety hazards.

Embodiment 1

[0035] Such as figure 1 as shown, figure 1It is the structural front view of the prefabricated brick tire mold mortise and tenon connection structure; the prefabricated brick tire mold mortise and tenon connection structure of the present invention includes a prefabricated plate group 1, a bottom support assembly 2 and a central support assembly 3, and the prefabricated plate group 1 It includes a number of prefabricated panels, the formwork frame is formed by placing the prefabricated panels on the base plate 4, and the bottom of the prefabricated panels is fixedly connected with the base plate 4 through the bottom support assembly 2, which is used to strengthen the prefabricated panels. The connection state of the board and the bottom board 4, the central support assembly 3 is arranged between the prefabricated boards in the prefabricated board group 1, and is used to fix the position state between the prefabricated boards, thereby forming a stable formwork construction stru...

Embodiment 2

[0051] The first prefabricated panel 11, the second prefabricated panel 12, the third prefabricated panel 13, and the fourth prefabricated panel 14 are all provided with structural steel bars, and the first connecting member 16 and the second prefabricated panel The connectors 18 are formed by extending the structural steel bars.

[0052] Specifically, the structural steel bars include main steel bars 111 and reinforcing steel bars 112, and the main steel bars 111 are arranged as multiple parallel and vertical straight steel bars or multiple rectangular steel bar frames according to the thickness of the prefabricated slab.

[0053] When it is set as a plurality of straight steel bars, the straight steel bars are all set at equal distances.

[0054] Such as Figure 5 as shown, Figure 5 It is a top view of the connection structure of the first prefabricated panel and the second prefabricated panel in the state of the main steel bar of the straight steel bar; on the first pref...

Embodiment 3

[0065] The construction method of the prefabricated brick tire mold mortise and tenon joint structure comprises the steps of:

[0066] S1, completing the construction of the base plate 4, and forming the fixing groove on the base plate 4;

[0067] S2, sequentially installing the prefabricated panels to form a formwork frame;

[0068] S3, installing the bottom support assembly 2 and the center support assembly 3;

[0069] S4, filling the connection cavity by pouring;

[0070] S5, backfilling the periphery of the formwork frame;

[0071] S6, dismantling the central support assembly 3 and performing main body pouring work.

[0072] In the step S2, when constructing a separate rectangular cross-section cap or ground beam, the second prefabricated panel 12 is first installed on the corresponding position of the bottom plate 4 according to the fixing groove, and the When the first prefabricated slab 11 is described, the first prefabricated slab 11 is lifted away from the upper e...

Abstract

The invention discloses a prefabricated brick moulding bed mortise and tenon joint structure and a construction method. The prefabricated brick moulding bed mortise and tenon joint structure comprisesa plurality of prefabricated slabs, wherein the prefabricated slabs are provided with clamping grooves and/or clamping pieces; the clamping grooves and the clamping pieces are connected in a one-to-one correspondence mode; a plurality of first connecting pieces are arranged in the clamping grooves; the clamping pieces comprise clamping blocks and second connecting pieces; the second connecting pieces are fixedly connected with the clamping blocks; the second connecting pieces and the first connecting pieces are connected in a one-to-one correspondence mode; the prefabricated slabs are provided with structural steel bars; and the first connecting pieces and the second connecting pieces are formed by extending the structural steel bars. According to the prefabricated brick moulding bed mortise and tenon joint structure and the construction method, through the structural arrangement of the prefabricated slabs, when the adjacent prefabricated slabs are connected, the structural steel barsin the adjacent prefabricated slabs are also connected, so that a complete steel bar structural part is formed, and the stability of the prefabricated brick moulding bed mortise and tenon joint structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated brick tire mold mortise and tenon joint structure and a construction method. Background technique [0002] The traditional method of using "brick tire formwork" as the side formwork of the basement cap and ground beam concrete is to use bricks as the formwork for the basement cap and ground beam reinforced concrete pouring. Brick tire formwork has been used for more than 30 years in the construction of basement foundations, caps, and ground beams as a sluice for pouring reinforced concrete, and it is still used in most areas, but in my country The southern region, such as the basement project that the inventor has participated in construction: Shanghai Pudong, Zhejiang Wenzhou, Guangdong Guangzhou, Shenzhen, Foshan, Zhongshan, Zhuhai and other coastal areas, when every excavation reaches about 2 meters below ±0.00, it will Water seepage, mud, quicksand ...
