Description

Technical Field

[0001] The utility model relates to the technical field of building foundations, in particular to a pre-buried assembled building foundation. Background Art

[0002] The foundation refers to the soil or rock mass that supports the foundation under the building. The soil layer used as the foundation of the building is divided into rock, crushed stone soil, sand, silt, clay and artificial fill. There are two types of foundations: natural foundation and artificial foundation (composite foundation). The natural foundation is a natural soil layer that does not require human reinforcement. The artificial foundation needs to be reinforced by humans, and common ones include stone chip cushion layer, sand cushion layer, mixed ash soil backfill and compaction. The building foundation is divided into natural foundation and artificial foundation. The foundation that can directly bear the load of the building without treatment is called a natural foundation. On the contrary, the foundation that needs to be treated by foundation treatment technology is called an artificial foundation. According to the structural form: strip foundation, independent foundation, full foundation and pile foundation. Strip foundation: When a building uses brick walls to bear the weight, the foundation under the wall is often set continuously to form a full-length strip foundation. Independent foundation: When the upper part of the building is a frame structure or a single column, an independent foundation is often used; if the column is prefabricated, a cup-shaped foundation is used. Full-floor foundation: When the load transmitted from the upper structure is large, the bearing capacity of the foundation is very low, and the independent foundation cannot meet the foundation requirements, the lower part of the building is often made into a whole reinforced concrete foundation, which is called a full-floor foundation.

[0003] For example, a Chinese authorized patent, a building foundation infrastructure with the announcement number CN211057833U, is designed to solve the problem that the contact area between the foundation and the ground is relatively small when people are building foundations, and the ground is easily sunken due to long-term gravity pressure. The following scheme is proposed, which includes a concrete bottom plate, a ring baffle is fixedly installed on the top of the concrete bottom plate, a concrete top plate is fixedly installed on the top of the ring baffle, a finished building is fixedly installed on the top of the concrete top plate, a support seat is fixedly installed on the bottom of the support seat, a support plate is fixedly installed on the bottom of the support plate, and a plurality of support columns are fixedly installed on the bottom of the support plate, and the bottom end of the support column is fixedly connected to the top of the concrete bottom plate. The utility model has a simple structure and is easy to use. It can disperse the load of the gravity of the entire building foundation, and at the same time make the concrete bottom plate evenly stressed, which is convenient for people to use.

[0004] The above-mentioned traditional foundation structure is generally an integrated design during use. However, when transporting the integrated foundation structure to the construction site, it is time-consuming and labor-intensive to carry, thereby increasing the transportation burden of the construction workers and reducing the foundation installation efficiency. Utility Model Content

[0005] 1. Technical issues to be solved

After the positioning strip is inserted into the positioning frame, the block is compressed and shrinks into the chamber, and the spring is driven to compress. When the positioning strip continues to move, the block corresponds to the slot, and the block is inserted into the slot under the rebound of the spring. At this point, the first foundation and the second foundation can be completely assembled. During transportation, the first foundation and the second foundation can be transported separately, achieving a better splitting effect, meeting the use requirements of construction, and improving the foundation installation efficiency, etc., solving the problems raised by the background technology.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example

[0031] Reference Figure 1-6As shown, a pre-buried assembled building foundation includes a first foundation 1 and a second foundation 2. A positioning bar 312 is fixed to the outer wall of the first foundation 1, and a positioning frame 311 is fixed to the top of the second foundation 2 and is sleeved on the outer wall of the positioning bar 312. The positioning frame 311 and the positioning bar 312 are connected by a limiting mechanism. The limiting mechanism includes a chamber 313, a block 314, a slot 315 and a spring 317. The chamber 313 is opened inside the positioning bar 312. The inner wall of the chamber 313 is connected to the block 314 through the spring 317. The outer wall of the positioning frame 311 is provided with a slot 315 corresponding to the block 314. The block 314 is pressed to be embedded into the chamber 313, and the spring 317 is driven to be compressed. Then the positioning frame 311 is sleeved on the outer wall of the positioning bar 312. When the block 314 corresponds to the slot 315, the block 314 can be driven to be inserted into the slot 315 under the elasticity of the spring 317, so as to achieve the effect of assembly locking. A guide hole 318 is opened inside the block 314, and a guide column 316 corresponding to the guide hole 318 is fixed on the inner wall of the chamber 313. The guide column 316 and the guide hole 318 can provide good stability to ensure that the block 314 is sufficiently stable. A fixing strip 319 is fixed to the inner wall of the chamber 313, and the fixing strip 319 is inserted into the block 314. The fixing strip 319 can be used to limit the rotation of the block 314, thereby further achieving a stabilizing effect. An inclined surface is provided on the outer wall of the block 314, and the inclined surface is distributed from front to back near the middle position of the second base 2. When the first base 1 and the second base 2 are installed, the inclined surface can contact the outer wall of the positioning frame 311, thereby driving the block 314 to automatically embed into the chamber 313, so that the spring 317 is compressed, thereby achieving the purpose of automatic locking.

[0032] A bottom column 411 is fixed at the bottom end of the first foundation 1, and an embedding portion 412 is fixed at the bottom of the bottom column 411. The embedding portion 412 is a cone, and the cone-shaped embedding portion 412 can facilitate the embedding of the first foundation 1, which is convenient for pre-embedded installation. Corresponding holes 413 are opened inside the first foundation 1 and the second foundation 2, and vertical steel bars 414 are inserted into the holes 413. The first foundation 1 and the second foundation 2 can be inserted through the vertical steel bars 414 to improve the firmness of the foundation structure.

[0033] A pouring port 415 and a pouring trough 416 are provided at the top of the second foundation 2. The pouring port 415 is located in the middle of the top of the second foundation 2. The pouring trough 416 is provided with several groups and is connected with the pouring port 415 and the hole 413. After the vertical steel bar 414 is inserted into the hole 413, the mixed concrete can be poured through the pouring port 415. The concrete flows into each hole 413 through the pouring trough 416, so that the concrete casts the first foundation 1, the second foundation 2 and the vertical steel bar 414 into a cast-in-place column, ensuring the stability of the foundation structure, and facilitating the pre-embedded use of the construction. After the pouring is completed, the concrete can block the pouring port 415, the pouring trough 416 and the hole 413, ensuring that the foundation is stable enough and not easy to be compressed and produce a gap. The outer wall of the vertical steel bar 414 is sleeved with a connecting sleeve 418, and the two adjacent groups of connecting sleeves 418 are fixedly connected by a connecting plate 417. The connection sleeve 418 and the connection sleeve 418 can be used to limit the connection between two adjacent vertical steel bars 414 in the front and back. During the installation process, it is ensured that the vertical steel bars 414 are tilted and will not deviate during the connection with the cement column to affect the construction progress.

[0034] Working principle: When the first base 1 and the second base 2 need to be assembled, the card block 314 on the right side is pressed to insert the card block 314 into the chamber 313. At this time, the card block 314 can slide along the outer wall of the guide column 316 and the fixing bar 319, and drive the spring 317 to be squeezed and compressed. Then, the positioning frame 311 is sleeved on the outer wall of the positioning bar 312, and the second base 2 is pushed from left to right to make the positioning bar 312 slide on the inner wall of the positioning frame 311. The outer wall inclined surface of the card block 314 on the left side contacts the positioning frame 311, and drives the card block 314 to automatically shrink. When the slot 315 corresponds to the card block 314, the elasticity of the spring 317 can drive the card block 314 to rebound, and the card block 314 is inserted into the slot 315, thereby achieving the purpose of locking the first base 1 and the second base 2 and realizing the assembly effect.

[0035] When needed, the vertical steel bar 414 is inserted into the hole 413, and then the connecting sleeve 418 is put on the outer wall of the vertical steel bar 414 for reinforcement, and the stirred concrete is added through the pouring port 415. The concrete flows into each hole 413 through the pouring trough 416 to achieve the effect of cast-in-place use.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
