Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of existing building elevator installation, especially relates to a kind of assembled mixed frame elevator installation structure and intermediate standard section, standard section. BACKGROUND

[0002] For existing residential elevator installation engineering, the elevator structure form and structure system commonly used at present mainly have three kinds: steel frame structure ( Figure 1 ), reinforced concrete shear wall structure ( Figure 2 ) and reinforced concrete frame structure ( Figure 3 ).

[0003] Steel frame elevator structure ( Figure 1 ) is more common. The structure form adopts square steel pipe or "H" shaped steel section, and is mostly six-column structure. Steel column and steel beam are welded and connected on site, and are gradually increased to roof. After structure construction is completed, side wall and elevator track and the like are installed and constructed. The main shortcomings of this method are that there are many welding positions on site, and construction quality is difficult to control; there are many sequential construction processes, and construction period is relatively long; scaffold needs to be erected, and there is a certain degree of disturbance to residents; steel structure has poor fire resistance, and elevator shaft fireproofing problem is difficult to solve; steel structure has relatively poor economy.

[0004] In actual application, a small number of projects use reinforced concrete shear wall structure ( Figure 2 ) and reinforced concrete frame structure ( Figure 3 ). The construction method of these two structures is the same as conventional reinforced concrete structure, and shaft wall and beam are poured layer by layer until roof. After main structure reaches strength, masonry partition wall (reinforced concrete frame structure shaft), plastering and decoration and equipment installation construction can be carried out. The main shortcomings of this method are that there are many cast-in-place concrete wet operations, and construction period is long; scaffold needs to be erected, and has great influence on residents' life; single-layer concrete demand is small, and is not suitable for purchase and transportation of ready-mixed concrete; construction formwork and steel reinforcement yard have certain requirements on site construction space.

[0005] A kind of assembled reinforced concrete shear wall elevator installation structure has recently appeared. On the basis of original cast-in-place reinforced concrete shear wall structure, elevator is split into several standard layer sections according to floor, and is sequentially connected from top to bottom. This structure can avoid the problem of cast-in-place concrete, but also has the shortcomings of large self-weight of elevator standard section, inconvenient on-site hoisting, too large single-section size, too many transportation conditions restrictions and the like.

[0006] The existing elevator installation structure form has application and each has shortcomings, and an elevator installation structure that can solve the shortcomings of the above structures, facilitate installation, improve installation efficiency and economy is urgently needed.

The splicing plate 32 is welded to the top end of the reserved angle steel 31, facilitating assembly and installation of the first high-strength bolt 33 from the outside. It is worth mentioning that the reserved angle steel 31 is only a preferred selection of the embodiment, and other section steels 111 can also be used, such as channel steels, I-beams (the depth of the web will determine whether the first high-strength bolt 33 is convenient to install, that is, whether the position of the assembly hole is reasonable), and the like.

[0100] In the embodiment, the prefabricated connecting beam 2 and the prefabricated frame 1 are assembly type installed. As a preferred embodiment of the embodiment, please refer to Figure 7 and Figure 8 The prefabricated connecting beam 2 is a three-section beam. Further, the prefabricated connecting beam 2 includes a middle beam body and steel connecting sections 22 at both ends, and the frame structure column 11 is further provided with a mounting corbel 13. The mounting corbel 13 and the steel connecting section 22 are assembly type connected and installed through a bolt assembly 14.

[0101] Further, please refer to Figure 7 and Figure 8 Figure 9 Figure 12 Figures 4-11 Figure 2 Figure 7 Figure 5 Figure 6 Figure 5 Figure 11 Figure 5 Figure 7 Figure 7 Figure 8 Figure 7 Figure 8 Figure 9 Figure 12 Figures 4-11 Figure 2 Figure 7 Figure 5 Figure 6 Figure 5 Figure 11 Figure 5 Figure 7 Figure 7 Figure 8 Figure 7 Figure 8 Figure 9 Figure 12 FigThe intermediate beam body comprises a steel skeleton 21 inside the beam body and a concrete structure formed by external pouring. The steel skeleton has steel connecting sections 22 extending outward at both ends. The mounting bracket 13 is welded to the steel skeleton of the frame structure column 11 and extends outward. The two are assembled and installed by the bolt assembly 14. Specifically, the bolt assembly 14 comprises a lap bridge plate 141 and a second high-strength bolt 142. The lap bridge plate 141 is lapped on the steel connecting section 22 and the mounting bracket 13 and is connected by the second high-strength bolt 142. It should be understood by those skilled in the art that the number of lap bridge plates 141 and second high-strength bolts 142 is not limited, and the purpose of rigid connection or hinged connection of the three-section beam and the mounting bracket 13 is achieved.

[0102] As another preferred embodiment of the present embodiment, the steel skeleton inside the intermediate beam body is an H-shaped steel, and the web of the H-shaped steel extends outward to form a steel connecting section. The web of the H-shaped steel and the mounting bracket can be directly connected by high-strength bolts to achieve hinged connection. Although this embodiment is not specifically illustrated, those skilled in the art should be able to understand it.

[0103] In the present embodiment, the use of a large number of prefabricated components improves construction efficiency, makes structural components prefabricated and standardized, and also reduces costs. In order to further improve the fire resistance of steel structures, the exposed assembly nodes of each steel structure are covered with concrete. Specifically, the mounting bracket 13 and the steel connecting section 22 form a first assembly node through the bolt assembly 14, and the first assembly node is covered with a first concrete coating layer 20. Similarly, the assembly components 3 of adjacent intermediate standard sections form a second assembly node, and the second assembly node is covered with a second concrete coating layer 30. Preferably, in order to prevent cracking, a steel mesh is wrapped around the assembly node, and then a formwork is set up for concrete pouring and coating.

[0104] Further, the shaft space 101 and the corridor space 102 form an outer peripheral wall, which is attached to the prefabricated frame 1 and the prefabricated connecting beam 2. That is, the outer peripheral wall is formed between the frame structure beam 12 and the frame structure column 11, the prefabricated connecting beam 2 and the frame structure column 11. Adaptively, the outer peripheral wall should provide an elevator door passage and a corridor passage according to actual needs, which is well known in the art and will not be described here.

[0105] It should be noted that the present embodiment also includes an elevator base section 4 and a prefabricated top cover section 5. The present embodiment does not limit the structure of the elevator base section 4 and the prefabricated top cover section 5. The elevator base section 4 is preferably a cast-in-place section, and the bottom of the intermediate standard section can be connected by pouring with the elevator base section 4. The prefabricated top cover section 5 can be installed by the same assembly component 3 through the connection method of the intermediate standard section, and will not be described here.

[0106] The beneficial effects of the present embodiment are:

[0107] The elevator structure is constructed in a full assembly mode, does not need concrete pouring wet operation, greatly improves construction efficiency, and reduces the interference of construction on residents due to no wet operation on site.

[0108] The standard layer of the elevator shaft is divided according to the standard frame and steel beam, effectively controls the self weight and size of the component unit, and is convenient for transportation and hoisting.

[0109] The frame structure columns between the intermediate standard sections are spliced through upper and lower reserved angle steels and splicing plates, assembled through high-strength bolts, and constructed layer by layer to form a firm and reliable whole elevator structure.

[0110] Each assembly joint is covered with concrete to effectively solve the defects of insufficient fire resistance of the steel frame structure and high maintenance requirement in the later period.
