Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tombstone and tomb making, in particular to a tombstone and tomb making process using foamed concrete. BACKGROUND

[0002] Traditional tombstones and tombs are usually made of stone materials, which have high raw material costs, are heavy, difficult to produce and transport, and have high transportation costs. The processing steps first cut and separate the stone into the required shape and size. For complex shapes, a carving machine must be used for carving and shaping. Because of the hardness of the stone, cutting and carving are difficult, time-consuming, and require expensive tools. Using foamed concrete to make tombstones and tombs by pouring is simple and fast. Foamed concrete has good fluidity, and the mold can be made in advance. The foamed concrete is poured into the mold to fill the complex details (such as texture, hollowing, and curved surface) in the mold. This can achieve the fine or special-shaped design that stone carving cannot achieve. The mold can be reused, and the same shaped product can be easily and repeatedly poured to further reduce costs and improve efficiency. Stone is heavy, with a density of 2600-2800 kg / m³. A 0.2x0.2x1m tombstone can easily weigh 104 kg, and ordinary people have difficulty moving it during production and transportation.

[0003] Moreover, in rural areas, tombs are usually made of soil, which will grow weeds over time. The soil tomb will shrink and become shorter over time due to rain erosion, and needs to be maintained annually, affecting the appearance. SUMMARY

[0004] The present application provides a tombstone and tomb making process using foamed concrete, which solves the problems of high cost, long cycle, poor structural stability, and low applicability during pouring.

[0005] The embodiments of the present application are implemented by the following technical solutions:

[0006] A tombstone and tomb making process using foamed concrete, comprising the following steps:

[0007] Step 1: According to the requirements of the tombstone and tomb, precast the corresponding concrete pouring mold;

[0008] Step 2: Stir the foamed concrete to produce a large number of uniform bubbles, then add cement and sand and stir evenly to form foamed concrete with internal bubbles;

[0009] Step 3: Pour the stirred foamed concrete into the precast concrete pouring mold to form the shape of the tombstone and tomb;

[0010] Step 4, after the poured tombstone tomb is solidified and formed, the mold is removed;

[0011] Step 5, the surface of the tombstone tomb is painted with paint or decorated with ceramic tiles and other materials;

[0012] Step 6, engraving the inscription.

[0013] Preferably, in step 2, the fiber filaments are added simultaneously while stirring the foamed concrete, or in step 3, the steel bars or fiber mesh are pre-embedded in the mold before pouring the foamed concrete.

[0014] Preferably, in step 6, the inscription is engraved on the poured tombstone body or on the material such as stone or ceramic tile that is pasted or inlaid.

[0015] Preferably, in step 4, the tombstone and the tomb are integrally formed or are formed in a split structure.

[0016] The technical solution of the embodiment of the present application has at least the following advantages and beneficial effects:

[0017] 1. The tombstone and tomb made of foamed concrete do not rely on traditional stone materials, and can be transported by manpower multiple times, which is flexible in selecting a tomb address in remote areas such as mountains and plateaus, and further reduces the difficulty of transporting raw materials.

[0018] 2. The cavity of the tomb formed by the prefabricated mold or flexible sheet is poured and formed in a factory or on site, which matches different tomb shapes, thereby replacing traditional expensive hard stone and special-shaped molds, and greatly reducing the material pouring cost and mold manufacturing cost.

[0019] 3. The integrally formed (or split) mold pouring simplifies the construction process and has lower requirements for the ground of the tomb address, and the foamed concrete can also make the tombstone and tomb durable and not prone to collapse, and does not need to be frequently maintained. DETAILED DESCRIPTION

[0020] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the application provided is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0022] Embodiments

[0023] The present application uses foamed concrete with a density of 600-800 kg / m3 to make the tombstone and tomb, and the weight of the 0.2x0.2x1m tombstone is only 24 kg, so the workers can carry it more easily during production and transportation, and the transportation cost is lower. In terms of raw material cost, the cost of cement, sand, foaming agent and other raw materials required to make one cubic meter of foamed concrete with a density of 600-800 kg / m3 is about 300 yuan, which is much lower than that of stone materials.

[0024] In the present embodiment, foamed concrete is used to cast the tombstone and tomb, and the tombstone and tomb casting process steps are as follows:

[0025] Step 1, according to the shape of the tombstone and tomb that you want to make, prepare the concrete casting mold in advance.

[0026] Among them, the casting mold is the core tool for cement product forming. Foamed concrete is in a slurry state before solidification, without fixed shape. The essence of the mold is to "shape it and ensure the stability of the hardening process". The mold, through its "cavity" (the space structure inside the mold), pours the mixed foamed concrete into the cavity of the mold, so that the foamed concrete can be shaped after solidification. The advantage is that it has strong batch replication capability. Once the mold is made, the same shaped products can be repeatedly cast and produced, greatly improving production efficiency, while stone carving needs to be processed individually by hand or machine.

[0027] The shape of the mold can be various, which can be made into a whole or into multiple parts to be assembled into a whole after foamed concrete is cast and shaped.

[0028] Step 2, mix the foamed concrete, mix the foaming agent with water to produce a large number of uniform bubbles, then mix the prepared foam with cement and sand to form foamed concrete with bubbles inside, so as to achieve the effect of reducing weight.

[0029] It is worth noting that the foamed concrete, also known as foam concrete, is a new type of building material formed by introducing a large number of closed or semi-closed bubbles in the concrete matrix to form a lightweight porous structure. It is made of cementitious materials (cement, lime, fly ash, etc.), mixed with aggregate (sand, ceramsite, perlite, etc.), and then mixed with special foam and poured into the mold after curing. The core features are lightweight, porous, heat preservation and insulation, and also have certain strength and durability.

[0030] During the mixing process, 1:25 foaming agent and water are mixed and stirred uniformly, and then the mixed water and foaming agent are used to produce a large number of bubbles (also can be made by rapid stirring method); the cement, sand, water and fiber silk in the proportion of 1:0.5:0.3:0.01 are stirred uniformly, and then the prepared foam is slowly stirred uniformly.

[0031] It is worth noting that the foamed concrete raw material ratio used in this embodiment is 600 kg / m³, and according to different requirements for product density and strength, the density and strength of the finished product can be adjusted by increasing or decreasing the proportion of cement and sand. In this embodiment, cement is used as cementitious material and sand is used as aggregate. Increasing or decreasing the amount of cement and sand (total water amount remains unchanged) can increase or decrease the density and strength of the foamed concrete after setting.

[0032] During the mixing process, fiber silk can be added to the foamed concrete to increase the strength of the foamed concrete after setting, thereby increasing the strength and surface crack resistance of the foamed concrete. If fiber silk is not used, steel bars or fiber silk mesh can be pre-embedded in the mold during the later pouring of the foamed concrete to increase the strength of the foamed concrete.

[0033] Step 3, pour the mixed foamed concrete into the prepared mold, and wait for the foamed concrete to set and form.

[0034] First, the surface of the mold is evenly coated with a layer of release agent or waste engine oil before pouring, to facilitate the release of the foamed concrete after setting. Pour the mixed foamed concrete into the prepared mold, and try to pour it evenly and slowly to fill all the gaps in the mold. After pouring, use a wooden stick or rubber hammer to gently tap the mold around to make the foamed concrete better fill the entire mold.

[0035] Step 4, remove the mold after the poured tombstone and tomb hole set and form.

[0036] After the foamed concrete sets, use a rubber hammer to gently tap the mold around to separate the mold from the foamed concrete, then slowly remove the mold to get the formed tombstone and tomb hole.

[0037] And the shape of the tombstone tomb can be varied by pouring forming, and can be integrally formed, or can be poured into several and assembled into a whole. The finished tombstone tomb can be a whole, or can be made into independent tombstone and independent tomb. The product thus made has various forms and can meet the various choices of consumers.

[0038] Step 5, the surface of the tombstone tomb is decorated, and the surface is painted with paint or other coating or is pasted with decorative materials such as ceramic tiles and stone materials, so as to beautify, and can also waterproof and increase the service life of the tombstone tomb.

[0039] Among them, the foamed concrete after pouring forming can be surface decorated after the surface is completely dry, and the surface is painted with paint or other coating or is pasted with decorative materials such as ceramic tiles and stone materials, so as to beautify, and can also waterproof and increase the service life of the tombstone tomb.

[0040] Step 6, engraving the epitaph.

[0041] Among them, the main purpose of engraving the epitaph on the tombstone is to record the identity information, life story and virtue of the deceased, and at the same time, to serve as a carrier for the living to remember and commemorate the deceased, to realize the emotional expression and the inheritance of life memory.

[0042] When engraving the epitaph, the epitaph can be directly engraved on the poured tombstone, or stone or ceramic tiles and other materials can be pasted or inlaid on the tombstone, and then the epitaph can be engraved on the pasted or inlaid stone or ceramic tiles and other materials. At the same time, the grade is improved and the appearance is increased, and the relevant information is recorded.

[0043] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
