Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to an assembled thermal insulation and sound insulation floor structure for newly-built residential buildings, schools, hospitals and other civil buildings.

[0002] The invention also relates to a method for laying an assembled thermal insulation and sound insulation floor structure. Background Art

[0003] The traditional floor insulation and sound insulation system has the disadvantages of complex process, difficulty in setting up steel mesh and expansion joint construction, easy cracking of the cast part protective layer, difficulty in controlling the thickness, 4 to 6 cm thickness of fine stone concrete accounting for the inner net height, high cost and long construction period, etc. In addition, a large number of wet operations deviate from the current goals of energy conservation, consumption reduction and environmental protection.

[0004] The patent with application number CN202210705505.2 discloses a pouring construction method for controlling cracks in thermal insulation and sound insulation floors, which includes the following steps in sequence: S1 cleaning the base layer; S2 making ash cakes with 1:3 cement mortar according to the elevation line, and setting two different heights of the ash cakes, with a height difference controlled at 10-15mm, and setting high ash cakes at the four corners and the middle of the room, and setting low ash cakes 50mm away from the wall, with a spacing of 50-60mm; S3 vertical sound insulation sheets should be bonded to the wall surface at the indoor corners; S4 concrete pouring; S5 after 2-3 hours of concrete slightly absorbing water and hardening, immediately press in the glass fiber mesh, the overlap of the glass fiber mesh is not less than 100mm, and ensure continuous arrangement; S6 control the concrete hardening time according to the pouring environment temperature to complete the secondary finishing. The present invention adopts a layered casting method for construction during the casting process. In order to ensure the anti-cracking effect, a glass fiber mesh is added to the surface layer. The structure is simple and easy to implement, which improves the anti-cracking ability of the thermal insulation floor, reduces later repairs, and saves costs.

[0005] However, the construction process of the above patented technology is complicated. The cast-in-place fine stone concrete protective layer requires manual laying of steel mesh, and the steel mesh needs to be laid close to the surface layer. If the steel mesh is not laid in the right position, the fine stone concrete layer is not properly maintained, the separation joints are not set reasonably, etc., cracking defects are very likely to occur. Summary of the invention

[0006] The purpose of the present invention is to provide an assembled thermal insulation and sound insulation floor structure to solve the problems raised in the above background technology:

[0007] (1) How to avoid the use of steel mesh, thereby avoiding the difficulty of expansion joint construction and the problem of easy cracking of the protective layer in the cast part.

[0008] The purpose of the present invention is to provide a method for laying an assembled thermal insulation and sound insulation floor structure to solve the problems raised in the above background technology:

[0009] (1) How to solve the problem that the traditional cast-in-place fine stone concrete protective layer requires artificial laying of steel mesh, and the fine stone concrete layer is not properly maintained and the separation joints are not set properly, which also makes it very easy to crack.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] An assembled thermal insulation and sound insulation floor structure;

[0012] It includes a number of support blocks and a number of thermal insulation and sound insulation panels;

[0013] A plurality of support blocks are distributed in an array and fixed on the floor slab of the flooring area to be laid, the thermal insulation and sound insulation panels are laid on the plurality of support blocks, and any adjacent thermal insulation and sound insulation panels are closely arranged, and the four corners of the thermal insulation and sound insulation panels are respectively fixedly connected to the support blocks, and the plurality of thermal insulation and sound insulation panels form a filling cavity between the plurality of support blocks and the floor slab, and the filling cavity is filled with a filling layer formed by curing an adhesive.

[0014] Based on the above technical solution, the present invention can also be improved as follows.

[0015] Furthermore, a casting hole communicating with the filling chamber is opened at the center of the thermal insulation and sound insulation board.

[0016] Furthermore, it also includes a plurality of vertical sound insulation sheets, which are laid on the wall surface beside the area where the floor is to be laid, and the thermal insulation sound insulation board close to one side of the wall is against the vertical sound insulation sheets.

[0017] With such a structure, the patented prefabricated thermal insulation and sound insulation floor structure provides a new type of building floor solution, which aims to improve the overall performance and quality of the building while reducing costs and environmental impact.

[0018] The adhesive can be a common bonding mortar prepared in a cement-sand mass ratio of 1:2.5 to 1:3, or a polymer bonding mortar made of high molecular polymer, cement and sand as main materials and having good bonding properties and certain deformation capacity.

[0019] The use of special adhesives and reasonable construction technology reduces cracking problems caused by temperature changes or other factors. Compared with traditional methods, prefabricated structures can reduce floor thickness, thereby increasing indoor net height. Prefabrication and dry construction greatly shorten the construction period and speed up the project progress. It reduces energy consumption and waste during construction, meeting the requirements of green buildings.

[0029] Furthermore, in the step f), after pouring the special adhesive, static curing is performed for 24 hours to ensure that the adhesive is fully cured.

[0030] The laying method of this assembled thermal insulation and sound insulation floor structure has the following advantages and effects:

[0031] (1) Factory prefabrication: The thermal insulation and sound insulation panels are prefabricated in the factory, and the quality is controllable.

[0032] (2) Dry assembly construction: Use dry construction to reduce on-site wet work and reduce environmental pollution.
