Description

Technical Field

[0001] The invention relates to building construction, in particular to a method for manufacturing and installing an SJF board suitable for a heat-insulating basement. Background Art

[0002] To maximize underground space utilization and meet practical needs, industrial and residential buildings generally have basements. Basement water seepage is a key issue in underground construction management. To address this common quality issue, engineering designers typically employ a composite waterproofing approach during building design. This involves combining waterproof concrete with waterproof membranes, waterproof coatings, and permeation crystallization to ensure a waterproof basement. This multi-faceted approach ensures effective basement waterproofing.

[0003] In order to prevent the waterproof membrane outside the waterproof concrete from being damaged, protective measures are usually provided outside the waterproof membrane. The protective measures usually include the following methods:

[0004] 50mm thick extruded board is pasted on the outside of the waterproof membrane;

[0005] The waterproof membrane is built with a 120mm thick brick wall;

[0006] A 50mm thick extruded board is pasted on the outside of the waterproof membrane and then a 120mm thick brick wall is built.

[0007] The aforementioned 50mm-thick extruded polystyrene sheet is essential for insulating basements, serving not only as a protective membrane but also as a thermal insulator. However, using only 50mm-thick extruded polystyrene sheet as waterproofing membrane in an insulated basement would be ineffective. The impact and compression of the extruded polystyrene sheet during the pouring and settling of the fertilizer trough would damage and dislodge the sheet. Building a 120mm-thick brick wall behind the 50mm-thick extruded polystyrene sheet would increase costs and construction time.

[0008] Comprehensive analysis shows that the main reasons for the poor protection of insulation board when pasting extruded board as the protective layer of waterproof membrane are as follows:

[0009] The side walls of the basement are relatively high, and traditional 1200mm×600mm×50mm extruded panels are used for staggered pasting. The upper and lower layers of extruded panels are prone to misalignment at the junction, which results in the upper extruded panels lacking the support of the bottom extruded panels. As a result, the upper extruded panels slide down under the influence of soil forces, thereby dragging the roll material down.

[0010] The compression strength of the extruded board itself is insufficient and its surface is rough. Even if the extruded board does not shift, the backfill soil of the fertilizer trough will produce friction with the surface of the extruded board, and the extruded board will be compressed under the action of soil pressure, pulling the roll material downward.

[0011] The Chinese utility model with authorization announcement number CN202559551U discloses a modified foamed cement insulation for wall insulation.

[0012] The utility model has a protective layer on the periphery of the thermal insulation layer, and the protective effect of the utility model is poor. Summary of the Invention

[0045] See also Figure 1-Figure 7This embodiment provides a method for manufacturing and installing an SJF board suitable for an insulated basement, which is carried out in the following steps:

[0046] A. Raw material preparation

[0047] Prepare cement, sand, gravel, prefabricated formwork, and extruded board raw materials.

[0048] B. Prefabricated cement board

[0049] Concrete is poured into the prefabricated formwork, and cement board 1 is prefabricated. Cement board 1 is cured and hoisted after reaching the designed strength. The thickness of cement board 1 is 8 mm, the width is 60 mm, and the height is consistent with the height of the basement side wall.

[0050] C. Drill rivet holes on cement board 1.

[0051] D. The smooth surface of the cement board 1 faces downward and the rough surface faces upward. The rivet 3 is installed on the cement board 1. The back cap 5 of the rivet 3 fits in with the smooth surface of the cement board 1. The top surface of the back cap 5 is provided with four fan-shaped grooves 6. The four grooves 6 are arranged in a cross shape. The column 4 of the rivet 3 passes through the rivet hole of the cement board 1 and extends out of the upper plate surface of the cement board 1. The column 4 of the rivet 3 is provided with barbs 7.

[0052] E. Extrusion molding

[0053] Cement board 1 serves as the base mold, with the smooth side facing downward and the rough side facing upward. Cement board 1 is placed on the extruder. Extruded board 2, 50 mm thick, is extruded onto cement board 1. The extruded board 2 forms the SJF board. The extruded board 2 of the finished SJF board is connected to the barbs 7 of the columns 4 and the rough side of cement board 1, forming a single piece. Once the SJF board has reached sufficient strength and is ready for production, it is transported to the construction site using slings.

[0054] F. Waterproof membrane is laid on the side walls of the insulated basement.

[0055] H, SJF board installation

[0056] Use bonding mortar to stick one side of the extruded board 2 of the SJF board to the waterproof membrane.

[0057] The working principle of the SJF board in this embodiment is:

[0058] During backfill, the cement board 1 side of the SJF board is in direct contact with the soil. The inherent strength of the cement board 1 resists the impact load of the soil, preventing damage to the SJF board. During soil settlement, the smooth surface of the cement board 1 makes it difficult to form an effective bond with the soil. Furthermore, the cement board 1's inherent strength prevents soil settlement from causing compression of the SJF.

[0059] The concrete surface, especially after the roll material is applied, has certain undulations. Under the influence of the earth side pressure, the SJF board is adjusted by the compression of the extruded board 2, so that the SJF board fits tightly with the structure. The SJF board is in a state of uniformly distributed load and the force is evenly distributed, thus avoiding shear damage of the SJF board.

[0060] The SJF board of the present invention is composed of a 50mm thick extruded board and an 8mm thick cement board. During SJF board production, the cement board serves as the base mold for the extruded board, resulting in a 60cm wide board with a height consistent with the basement side wall. To ensure a secure connection between the cement board and the extruded board, matching plastic embedded parts are used to connect the two. After production, the extruded board and cement board are integrally connected, and together they provide protection for the waterproof membrane, achieving excellent waterproof membrane protection.

[0061] The basic principles, main features and advantages of the present invention are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
