Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a multi-rib sandwich floor slab without disassembly of formwork. Background Art

[0002] The floor slab is a crucial component of a building structure, serving as the floor between floors. The most widely used structural type is reinforced concrete, which offers advantages such as high load-bearing capacity, fire resistance, and durability. However, its disadvantages include heavy weight and relatively poor sound and thermal insulation properties.

[0003] As prefabricated buildings, reinforced concrete composite floor slabs are mainly used. Although they have the advantages of simple production process, easy installation, fast construction, and safe and reliable structure, these composite floor slabs are mostly solid slabs, with heavy weight and small application span. At the same time, post-cast composite layer construction is also required. Therefore, the current cost of composite floor slabs is generally higher than that of cast-in-place slabs. Utility Model Content

[0004] In order to provide a floor slab with low cost, fast construction speed and good thermal insulation effect, the utility model proposes a multi-rib sandwich floor slab without dismantling formwork.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multi-rib sandwich floor with a non-disassembly formwork comprises a non-disassembly base plate, a plurality of equally spaced fillers are arranged on the upper surface of the non-disassembly base plate, cast-in-place longitudinal ribs and cast-in-place transverse ribs are arranged on the upper surface of the non-disassembly base plate and the periphery of the fillers, a cast-in-place panel is arranged on the upper surface of the fillers, the cast-in-place longitudinal ribs and the cast-in-place transverse ribs, and the non-disassembly base plate and the fillers are connected by fasteners.

[0007] As a further improvement of the above technical solution:

[0008] Preferably, the non-disassembly base plate is a non-disassembly high-strength fiber cement board.

[0009] Preferably, the filler is a recycled aggregate concrete sandwich filling box.

[0010] Preferably, the fastener is a self-tapping screw.

[0011] Preferably, a plurality of fasteners are provided under each of the fillers.

[0012] Preferably, the four fasteners are arranged on the four corners of the filler.

[0013] Preferably, the filler includes solid filler, sandwich filler and hollow filler.

[0014] Compared with the existing technology, the beneficial effects of the utility model are:

[0015] The utility model designs a formwork-free floor slab, which adopts a concrete structure and filler, which saves production costs to a certain extent. At the same time, the presence of the filler has an insulation effect. In order to ensure the stability of the process of pouring longitudinal and transverse ribs and panels and the transportation process, a number of self-tapping screws are used for fixing to ensure its stability. At the same time, because it is a formwork-free cover, the installation process is relatively simple and quick, and there is no need for complicated installation and disassembly work like traditional formwork, thereby saving construction time. Since the formwork-free formwork does not need to be dismantled, the next step can be carried out directly after the construction is completed, which greatly shortens the overall construction period.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] The technical solution is as follows:

[0025] like Figure 1 With attached Figure 2 As shown, this scheme is divided into three layers from the bottom right to the top, as follows:

[0026] The first layer is the bottommost non-disassembly high-strength fiber cement board 1, and of course other non-disassembly bottom boards can also be used.

[0027] The second layer is the filling layer, specifically a number of equally spaced recycled aggregate concrete sandwich filling boxes 2 arranged on the upper end of the non-dismantling high-strength fiber cement board 1. The use of the filling layer is beneficial to the thermal insulation effect. Secondly, the use of recycled aggregate concrete reduces the dead weight of the concrete and makes full use of the two renewable resources of recycled aggregate, realizing waste utilization, saving resources, reducing production costs and reducing pollution to the environment. Of course, if other types of filling materials are used, it is also acceptable. Cast-in-place transverse ribs 5 and cast-in-place longitudinal ribs 4 are cast around the recycled aggregate concrete sandwich filling box 2.

[0028] At the same time, in order to prevent movement during the pouring process and the transportation process, self-tapping screws 3 are used between the non-disassembly high-strength fiber cement board 1 and the recycled aggregate concrete sandwich filling box 2 for connection, fixation and limitation. Other similar fasteners can also be used. Self-tapping screws 3 are set on the four corners of each recycled aggregate concrete sandwich filling box 2.

[0029] The third layer is a panel, in which a layer of cast-in-place panel 6 is covered on the upper end of the cast-in-place transverse ribs 5, cast-in-place longitudinal ribs 4 and the recycled aggregate concrete sandwich filling box 2.

[0030] The processing and use process of this utility model:

[0031] 1. Install the processing bracket and lay a layer of non-removable high-strength fiber cement board 1 on the bracket.

[0032] 2. Place the corresponding number of recycled aggregate concrete sandwich filling boxes 2 on the non-dismantling high-strength fiber cement board 1 and fix them with self-tapping screws 3. For the recycled aggregate concrete sandwich filling boxes 2, attach Figure 1 It is a solid recycled aggregate concrete sandwich filling box 2, but it can also be as shown in the attached Figure 2The sandwiched recycled aggregate concrete filling box 2 and the attached Figure 3 The hollow recycled aggregate concrete sandwich filling box 2 is shown.

[0033] 3. Pour concrete to form cast-in-place transverse ribs 5, cast-in-place longitudinal ribs 4 and cast-in-place panels 6.

[0034] 4. Remove the adjacent formwork and bracket to get the floor slab.

[0035] 5. When using, just hoist it directly.

[0036] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
