Description

TECHNICAL FIELD

[0001] The utility model relates to building enclosure technology field especially, relates to a foundation structure for prefabricated enclosure. BACKGROUND

[0002] However, with the development of construction technology, the use of prefabricated concrete construction is gradually accepted by people, which is to prefabricate concrete parts in the factory first, then transport to the construction site for splicing construction. Compared with traditional construction, it has the advantages of fast construction period and convenience.

[0003] However, for the existing construction process of building enclosure, since the building enclosure includes enclosure foundation, stand and enclosure between adjacent stands, the foundation pit is excavated at the fixed point on site, and then the enclosure foundation is made by binding steel bars and pouring concrete in the foundation pit; after the stability of the enclosure foundation structure, the stand is set on the enclosure foundation, the steel bars are bound, and the concrete is poured under the condition of building formwork to realize the connection of the enclosure foundation and the stand.

[0004] The above process is complex and tedious, and the construction period is long. Since the enclosure foundation is poured on site, its structure is single, which makes the fixing of the formwork during the pouring of the concrete more troublesome, and when the formwork is unstable, the formwork will collapse and affect the pouring construction during the pouring of the concrete. Based on this, we propose a foundation structure for prefabricated enclosure. UTILITY MODEL CONTENT

[0005] The utility model aims at solving the shortcomings in the prior art and provides a foundation structure for prefabricated enclosure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A foundation structure for prefabricated enclosure, comprising a base and a positioning outer connecting component, the middle part of the upper surface of the base is provided with a sinking butt joint groove, the upper surface of the base corresponding to the outside of the sinking butt joint groove is arranged with a plurality of U-shaped steel bars at intervals, and the lower end of the U-shaped steel bar is open and extends into the base.

[0008] The U-shaped steel bar forms an outer connecting steel bar frame between the U-shaped steel bars, the upper surface of the base corresponding to the outside of the outer connecting steel bar frame is embedded with a plurality of outer connecting rods, and the lower end of the outer connecting rod extends into the base.

[0009] The positioning outer connecting assembly comprises a base plate, a baffle and an outer plate, the base plate is provided with through holes at both ends and is sleeved on the adjacent outer connecting rods, the baffle is vertically arranged and is welded on the surface of the base plate on the side facing the outer connecting steel ring frame, and the outer plate is welded on the upper end surface of the baffle and is flush with the side of the baffle facing the outer connecting steel ring frame.

[0010] The outer plate is provided with an outer connecting hole.

[0011] Preferably, the base is a reinforced concrete structure, and the part of the lower end of the U-shaped steel frame located in the base is tied with the steel structure in the base.

[0012] Preferably, the part of the lower end of the outer connecting rod located in the base is tied with the steel structure in the base.

[0013] Preferably, the part of the outer connecting rod extending above the base plate is provided with a threaded groove, and a nut is installed on the upper end of the outer connecting rod through the threaded groove.

[0014] Preferably, the side of the baffle away from the outer connecting steel ring frame is welded with a reinforcing rib plate, and the lower end of the reinforcing rib plate is welded with the upper surface of the base plate.

[0015] The prefabricated foundation structure for the enclosing wall has the advantages that:

[0016] 1. The foundation structure for the enclosing wall in the technical solution can be prefabricated in a factory and then directly transported to a construction site of the enclosing wall, and in the case of being placed in a foundation pit in the construction site, the connection construction between the foundation structure and the stand column can be immediately carried out, that is, compared with the construction process of the enclosing wall foundation in the traditional construction process of the enclosing wall, the construction period is greatly shortened.

[0017] 2. In the construction process of connecting with the stand column, since the outer connecting steel ring frame composed of the U-shaped steel frame exists on the upper surface of the base, the construction step of tying the steel bars between the enclosing wall foundation and the column in the traditional construction process of the enclosing wall is avoided, and for the construction of the formwork, the lower part of the formwork can be attached to the side of the baffle facing the sinking butt joint groove, and at this time, the outer connecting hole on the outer plate can be quickly connected with the protruding structure outside the formwork by using the bolt, so that the formwork is quickly and conveniently constructed and installed.

[0018] 3. In the case that the formwork is constructed, a small amount of concrete is poured into the sinking butt joint groove first, the lower end of the stand column is placed in the sinking butt joint groove, and in the case that the outer surface of the lower end of the stand column has a certain distance from the groove edge of the sinking butt joint groove, the subsequent pouring of the concrete can be carried out, and since the lower part of the formwork is in relatively reliable connection with the positioning outer connecting assembly, the stability of the formwork is ensured, and the formwork collapse phenomenon in the concrete pouring process is avoided.

[0019] 4. As the poured concrete solidifies, the construction between the foundation structure of the wall and the columns is completed. The entire construction process is simple, convenient, fast, and short in cycle, which is conducive to the rapid construction of the wall. After the construction is completed, the template-based construction and installation are fast and convenient, so the removal of the template also becomes simple and convenient. Furthermore, the positioning external components on the base can be disassembled after removing the nuts for use by the factory in the prefabrication process of the next foundation structure of the wall, thereby realizing the reuse of the positioning external components.
