Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of assembly structure, especially relates to a prefabricated concrete house structure. BACKGROUND

[0002] In the modern construction industry, prefabricated house structures are increasingly valued for their efficiency, environmental friendliness, and recyclability. This structure form improves construction speed and reduces construction cost by prefabricating house components in factories and quickly assembling them on the construction site. However, despite the many advantages of prefabricated house structures, there are still some significant problems to be solved in practical application, especially in the installation of floor heating systems.

[0003] Currently, prefabricated concrete floors on the market often fail to fully consider the installation needs of floor heating systems in their design. Traditional floor heating installation methods, such as cutting grooves or filling and fixing, are not only cumbersome and costly, but also inefficient, greatly limiting the promotion and application of prefabricated house structures. In addition, these methods may also damage the structural integrity of the concrete floor during installation, affecting its service life and safety.

[0004] On the other hand, existing prefabricated concrete floors also have many inconveniences in assembly and fixation. Traditional fixation methods often rely on a large amount of cement mortar and other materials for bonding and fixation, not only increasing construction difficulty and cost, but also causing great difficulty in later removal and recycling. This not only wastes resources, but also increases the generation of construction waste, causing adverse effects on the environment.

[0005] In addition, traditional prefabricated concrete floors require cement mortar smoothing and brick laying operations when laying tiles, which is a complex and inefficient construction process, and the joint work also increases the construction workload and cost. These problems limit the further promotion and application of prefabricated concrete floors. SUMMARY

[0006] To overcome the shortcomings of the prior art, the utility model provides a prefabricated concrete house structure, which has the advantages of convenient installation of floor heating and tiles and recycling, solving some problems in the background art.

[0007] This utility model provides the following technical solution: a precast concrete assembly house structure, including a lower concrete floor and an upper concrete floor. Both the lower and upper concrete floors have concave grooves at their adjacent ends. Removable insulation boards are installed inside the concave grooves. Semicircular grooves are connected end-to-end at the adjacent ends of the insulation boards. Underfloor heating pipes are installed inside the semicircular grooves, and the pipes are adapted to fit the grooves. The upper end of the upper concrete floor has evenly distributed square grooves. Removable floor tiles are installed inside the square grooves, and the lower ends of the tiles are adapted to fit the grooves. The thickness of the floor tiles is greater than the depth of the grooves, and protruding edges are provided at all four ends of the protruding parts. The floor tiles are joined together in pairs through these protruding edges.

[0008] Furthermore, anti-slip posts are pre-embedded at the upper end of the concrete lower floor near the edge, and anti-slip grooves are provided at the lower end of the concrete upper floor near the edge. The upper ends of the anti-slip posts penetrate into the interior of the anti-slip grooves, creating a layered design for easy assembly and disassembly.

[0009] Furthermore, a floor heating reflective film is laid between the inner bottom of the groove in the concrete floor and the insulation board to prevent the floor heating temperature from flowing downwards and to ensure the heating effect.

[0010] Furthermore, the rear end of the concrete subfloor has pre-embedded splicing blocks near both sides, and the front end of the concrete subfloor has splicing grooves near both sides. The splicing blocks and splicing grooves are compatible with each other and can be used for expansion when a larger floor area is needed. Assembly is also simple and convenient.

[0011] Furthermore, a fixing hole is provided in the middle of the splicing block, and a detachable insert rod is inserted into the fixing hole. The upper end of the insert rod penetrates through the concrete floor. The fixing hole can also be used for hoisting.

[0012] Furthermore, at the four ends between the lower concrete floor and the upper concrete floor, there are multiple semi-circular grooves II corresponding to the underfloor heating pipes. The semi-circular grooves II are adapted to the underfloor heating pipes and are used when the underfloor heating pipes extend through the semi-circular grooves II to other areas.

[0013] The advantages of this utility model are as follows:

[0014] 1. Compared with the traditional grooving or filling fixing method, this solution only requires inserting the underfloor heating pipes along the semi-circular groove on the insulation board. The operation is simple and efficient, greatly shortening the construction time and reducing labor costs. At the same time, the concrete upper and lower floors can be quickly installed and fixed through the cooperation of anti-slip grooves and anti-slip columns, further improving the overall construction efficiency.

[0015] 2, the prefabricated house structure is convenient for later demolition, realizes the mobile and recyclable purposes, effectively reduces the operation amount and the generation of construction waste, improves the resource utilization rate, and moreover, the square groove of pre-design can be directly placed into the floor tile, without cement mortar smoothing and bricklaying operation, saves the joint work, not only reduces the construction workload, but also reduces the waste of building materials, is more environmental protection and energy saving.
