Description

Technical Field

[0001] This utility model belongs to the field of building construction technology and relates to a basement beam-slab-column structure. Background Technology

[0002] Beams and slabs are the basic transverse load-bearing components of a frame structure. The slabs bear the weight and transfer it to the beams, which then transfer it to the columns at both ends. The columns are important vertical load-bearing components of the frame structure, bearing the weight transmitted from the beams and then transferring it to the foundation. Their essential function is to bear various weights. Currently, the beams and columns of the basement need to be constructed on-site with bricks, which is slow and inefficient. In addition, the current construction of beams, slabs, columns and walls may be quite troublesome and may affect the construction efficiency.

[0003] For example, a Chinese patent discloses a cantilevered, non-removable formwork beam-slab for a basement [application number: 201920734666.8]. A slab end connector is installed at the junction of the slab bottom formwork and the first basement level; the slab formwork tie bars are securely connected to the hanging rod connecting plate; an outer beam formwork is installed at the bottom beam level, and the outer beam formwork is securely connected to the backfill layer at the bottom of the beam through beam formwork support bars and support bar bottom plates; formwork reinforcement bars are installed at the junction of the outer beam formwork and the slab bottom formwork; a steel reinforcement support body connected to the slab's internal bolts is installed on the bottom slab formwork; rod end grooves and hanging beam grooves are respectively arranged on the outer wall of the first basement level, and a sliding connector is installed in the rod end groove; the two ends of the sliding hanging beam are respectively inserted into the corresponding hanging beam grooves; after the sliding hanging beam slides to the set position, the sliding hanging beam is used as a construction platform for the concrete pouring of the first basement bottom slab and bottom slab beam. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a basement beam-slab-column structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A basement beam-slab-column structure includes a basement main body composed of several composite walls. The composite walls include composite support columns and several connecting plates connected to the composite support columns. The composite support columns are formed by splicing together a No. 1 precast concrete pile, several No. 2 precast concrete piles, and a No. 3 precast concrete pile. Each of the No. 1, No. 2, and No. 3 precast concrete piles is provided with a connecting plate installation groove, and the connecting end of the connecting plate is inserted into the connecting plate installation groove.

[0007] In the aforementioned basement beam-slab-column structure, the combined support column is pre-installed with a pouring groove for concrete pouring.

[0008] In the aforementioned basement beam-slab-column structure, the combined support column is also equipped with a splicing and positioning structure.

[0009] In the aforementioned basement beam-slab-column structure, the splicing and positioning structure includes a positioning groove recessed at the bottom of the No. 1 and No. 2 precast concrete piles, and a positioning block protruding at the top of the No. 2 and No. 3 precast concrete piles.

[0010] In the aforementioned basement beam-slab-column structure, the positioning groove and positioning block have rectangular annular cross-sections.

[0011] In the aforementioned basement beam-slab-column structure, both the positioning groove and the positioning block are connected to the pouring groove.

[0012] In the aforementioned basement beam-slab-column structure, the opening of the grouting groove is located at the top of the No. 1 precast concrete pile.

[0013] In the aforementioned basement beam-slab-column structure, the end of the connecting plate abuts against the side of the combined support column, and the inner end of the connecting plate is connected to the grouting groove.

[0014] In the aforementioned basement beam-slab-column structure, the composite support column is also equipped with a steel reinforcement cage.

[0015] In the aforementioned basement beam-slab-column structure, the steel reinforcement cage is formed by welding together several horizontally arranged transverse and longitudinal steel bars and several vertical steel bars.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. The modular support columns that make up the main body of the basement can be prefabricated in the factory and assembled on site, which can greatly speed up the construction efficiency. The connecting plates and modular support columns can also be assembled on site, which can improve the construction efficiency. The No. 1, No. 2 and No. 3 precast concrete piles can be prefabricated in the factory and assembled on site, which can speed up the construction efficiency. The overall height of the modular support columns can be adjusted by increasing or decreasing the number of No. 2 precast concrete piles.

[0018] 2. Setting up a grouting groove inside the modular support column allows for on-site pouring after the modular support column is assembled on the construction site. This not only reduces the weight of the No. 1, No. 2, and No. 3 precast concrete piles, making transportation easier, but also allows for the overall fixing of the assembled modular support column on the construction site without the need for other fixing accessories.

[0019] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

The positioning groove 12 and the positioning block can be used to fix adjacent first precast concrete pile 5 and second precast concrete pile 6, second precast concrete pile 6 and second precast concrete pile 6, and second precast concrete pile 6 and third precast concrete pile 7.

[0030] Specifically, the positioning groove 12 and the positioning block 13 have rectangular annular cross sections, and both the positioning groove 12 and the positioning block 13 are connected to the pouring groove 10.

[0031] Specifically, the opening of the grouting groove 10 is located at the top of the No. 1 precast concrete pile 5.

[0032] Specifically, the end of the connecting plate 4 abuts against the side of the combined support column 3, and the inner end of the connecting end 9 of the connecting plate 4 is connected to the grouting groove 10.

[0033] Preferably, the composite support column 3 is further provided with a steel reinforcement cage 14, which is formed by welding together several horizontally arranged transverse and longitudinal steel bars 15 and several vertical steel bars 16. The steel reinforcement cage can increase the overall strength of the composite support column.
