Embodiment 1

[0049] Embodiment 1: as figure 1 As shown, a reinforced concrete prefabricated theater stand structure includes a main structure 1 composed of a main structural beam 11 and a main structural plate 12 connected to the main structural beam 11, and a stand column 2 is connected to the main structure 1, and the stand The stand 3 is connected to the column 2; both the stand column 2 and the stand 3 are prefabricated reinforced concrete parts; between the adjacent stand 3 and the stand, between the stand 3 and the stand 2, the stand 2 It is connected with the main structure 1 through a preset connection structure with steel bars or / and steel plates and high-strength non-shrinkage adhesive grout 4, so that the main structure 1, all the stand columns 2 and all the stand boards 3 are all connected together to form a strong monolithic structure. High-strength non-shrinkage grouting material has high-strength and high-binding properties, and has the advantages of high fluidity without v...

Embodiment 2

[0056] Embodiment 2: The connection structure between the stand column 2 and the main structure 1 is that the lower end of the stand column 2 is provided with a prefabricated steel concrete column 22, and the anchor bar 27 is connected to the prefabricated steel concrete column 22, and the lower end of the anchor bar is implanted in the main structural beam, and finally Water the high-strength non-shrinkage adhesive grout 4 slurry, and the rest of the structure is the same as in Example 1, see Figure 10 .

Embodiment 3

[0057] Embodiment 3: The connection structure between the stand column 2 and the main structure 1 is that the lower end of the stand column 2 is inserted into the prefabricated steel concrete beam 6 and poured with high-strength non-shrinkage adhesive grouting material 4, and the outside of the prefabricated steel concrete beam 6 is spaced apart. Covered with a number of outer jacket square steel sleeves 7, the lower end of each outer jacket square steel sleeve 7 is welded with a connecting steel plate as a flange and welded with 2-4 evenly distributed stiffeners 26. The prefabricated steel concrete beam 6 is connected to the main structural plate 12, and the rest of the structure is the same as that of Embodiment 1 or Embodiment 2. see figure 1 , figure 2 , Figure 11 , Figure 12 , Figure 13 .

Abstract

The invention discloses a prefabricated reinforced concrete cinema stand structure. The prefabricated reinforced concrete cinema stand structure comprises a main structural beam and a main body structure composed of a main structural board and connected to the main structural beam, the main body structure is connected with stand columns, and the stand columns are connected with stand boards; the stand columns and the stand boards are all reinforced concrete prefabricated parts prefabricated by a plant; the adjacent stand boards, the stand boards and the stand columns, and the stand columns andthe main body structure are all connected through a preset connecting structure provided with rebar or / and steel plates and cooperating with a high-strength shrinkage-free adhesive grouting material,so that the main body structure, all the stand columns and all the stand boards are connected to form a rigid integrated structure. The prefabricated reinforced concrete cinema stand structure has the advantages that the integrated structure is in firm connection by using prefabricated parts, implanting the rebar into the joint site, or adding anchor bolts and cooperating with the high-strength shrinkage-free adhesive grouting material, the efficiency can be improved, and the materials and labor-hour are saved.

Description

technical field [0001] The invention relates to the technical field of theater construction, in particular to a prefabricated theater stand structure. Background technique [0002] The theater stand structure is the secondary structure of the main building, and is generally designed and constructed after the completion of the main structure. There are two types of conventional stand structures, one is the cast-in-place reinforced concrete stand structure, that is, the stand board is supported by columns or walls, and the walls, columns and boards are all made of cast-in-place reinforced concrete; the other is the steel frame stand structure, namely The main body of the stand adopts a steel frame structure, and the part of the stand is cast-in-place reinforced concrete after laying checkered steel plates on the frame. The cast-in-place reinforced concrete stand structure requires formwork, and concrete pouring requires pumping of concrete. The on-site construction workload i...
