Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and particularly relates to an emergency prefabricated strip foundation for a building. Background Art

[0002] The function of a building foundation is to bear the loads transmitted from the superstructure of the building and transmit them together with its own weight to the foundation; permanent buildings, temporary buildings with a long period of use, temporary buildings with important strategic significance, emergency buildings, etc. must all be built on a solid foundation and subgrade to ensure that the building has a high structural reliability, safety and comfort of use; among them, emergency buildings refer to flexible and adaptable shelters provided for people during social unrest or natural disasters. The number of floors should not be too many. In order to ensure the efficiency and safety of design, production and construction, they are generally 2-4 floors.

[0003] A strip foundation is a type of foundation in which the length is much longer than the width, with the length being greater than or equal to 10 times the width. Based on the superstructure, it is divided into wall-mounted strip foundations and column-mounted strip foundations. Due to its good applicability to low-rise and multi-story buildings, strip foundations have been widely used in emergency-type buildings. However, at this stage, strip foundations require designers to produce construction drawings based on design conditions and load requirements. Construction units then excavate foundation trenches on-site according to the drawings and cast them in situ. The main process includes construction drawing design, on-site measurement and layout, foundation trench excavation, formwork installation, steel bar tying, embedded parts embedding, concrete pouring, concrete curing and molding, and backfilling. The on-site work processes are complex, the workload is large, and many types of workers are involved. Therefore, using traditional cast-in-situ methods to set up strip foundations for emergency-type buildings will not only increase construction costs but also extend the construction period.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 6An embodiment of the present invention provides an emergency prefabricated strip foundation for a building, comprising a first base module 1, a second base module 2, and a plurality of crossbeam modules 3. The first base module 1 and the second base module 2 are detachably connected to each other via the plurality of crossbeam modules 3. The ends of the plurality of crossbeam modules 3 are detachably connected to the first base module 1 and the second base module 2, respectively. The tops of the first base module 1 and the second base module 2 are pre-embedded with a plurality of connectors 4 for connecting to the building superstructure. The bottom of the first base module 1 is provided with a plurality of arranged first steel bar reserved channels, the bottom of the second base module 2 is provided with a plurality of arranged second steel bar reserved channels, and the bottoms of the plurality of crossbeam modules 3 are provided with a plurality of arranged third steel bar reserved channels, wherein each third steel bar reserved channel corresponds to each first steel bar reserved channel and each second steel bar reserved channel. The number of crossbeam modules 3 can be determined according to actual construction requirements. In some practical application scenarios, a strip foundation of a desired length can be obtained by changing the number of crossbeam modules 3. The structural form and pre-embedded number of the connectors 4 may be determined according to actual construction requirements. Optionally, the connectors 4 are anchor bolts. Schematically, four connectors 4 are pre-embedded on the top of the first base module 1 and the second base module 2 .

[0029] The construction process of the emergency prefabricated strip foundation of this embodiment is as follows:

[0030] During construction, according to the construction requirements, the required number of first base modules 1, second base modules 2 and beam modules 3 are transported to the construction site, and then the modules are connected end to end in sequence according to the assembly principle of "base modules at both ends and beam modules 3 in the middle". When connecting, the reserved steel bar channels of each module are aligned and obstacles in the channels are removed. After the assembly is completed, the size and the position and quantity of each embedded part (such as the position and quantity of the connector 4) are reviewed; after the review is correct, the pre-prepared prestressed steel bars are passed through each reserved steel bar channel and the existing anchors are used to fix the two ends of each prestressed steel bar, thereby completing the assembly of the strip foundation; the upper structure of the building can be quickly and reliably connected to the entire strip foundation through the connector 4 pre-embedded on the first base module 1 and the second base module 2.

[0031] The prefabricated strip foundation for emergency buildings in this embodiment is based on the design concept of standardization and modularization. By prefabricating strip foundations suitable for emergency buildings into different standardized modules, during on-site construction, it is only necessary to assemble the various base modules and beam modules 3 according to the construction requirements to quickly form a strip foundation of the required length. This is very convenient and fast. Moreover, the various component modules can be reused. Therefore, compared with the traditional method of setting up strip foundations for emergency buildings using a cast-in-place method, it can not only effectively reduce the construction cost of emergency buildings, but also effectively shorten the construction period of emergency buildings.

[0032] Further, refer to Figures 1 to 3 In a preferred embodiment, the top of the first base module 1 has a first prism-shaped support platform 12, and a plurality of connecting members 4 are pre-embedded on the top of the first support platform 12; the top of the second base module 2 has a second prism-shaped support platform 22, and a plurality of connecting members 4 are pre-embedded on the top of the second support platform 22.

[0033] In this embodiment, based on the above structural design, by setting a support platform with a narrow upper and wide lower prism shape on the top of the two base modules as the anchoring part of the connecting member 4, a good force transmission mechanism can be provided, so that the entire strip foundation can better withstand the load transmitted from the upper structure of the building.

[0034] Further, refer to Figure 1 、 Figure 4 and Figure 5 In order to facilitate the lifting of the beam modules 3 during production, transportation, and turnover, in a preferred embodiment, several hooks are embedded on the top of several beam modules 3.

It should be noted here that the structural forms of the first connecting tongue and groove 13, the second connecting tongue and groove 23, the third connecting tongue and groove 33 and the fourth connecting tongue and groove 34 can be flexibly set according to actual construction requirements. Diagrammatically, the first connecting tongue and groove 13 and the fourth connecting tongue and groove 34 are both in the shape of a step with "convex on top and concave on bottom", and the second connecting tongue and groove 23 and the third connecting tongue and groove 33 are both in the shape of a step with "concave on top and convex on bottom"; of course, in some other embodiments, the first connecting tongue and groove 13 and the fourth connecting tongue and groove 34 can also be designed as a protrusion in the shape of an "I" or a "X", and correspondingly, the second connecting tongue and groove 23 and the third connecting tongue and groove 33 can be designed as a groove in the shape of an "I" or a "X", and so on. As long as the detachable cooperation between the first base module 1 and the beam module 3, between the second base module 2 and the beam module 3, and between the beam modules 3 and the beam modules 3 can be achieved, this embodiment does not make any specific restrictions on this.
