Description

Lightweight precast concrete wall panels or panels

technical field

The utility model relates to a concrete wall board or a board, in particular to a lightweight precast concrete wall board or board.

Background technique

In building structures, reinforced concrete slab structures are often used, such as building exterior wall panels, structural floor slabs, etc. The general practice is divided into on-site casting methods of laying steel bars, formwork, and pouring concrete on site, and pre-casting elsewhere. However, in order to reduce the cost, shorten the construction period and reduce the troubles of on-site construction, a large number of precast products have been used for reinforced concrete components, and the external wall panels, floor slabs or vertical wall panels of buildings are used in practice. Precast reinforced concrete slabs have been widely used in China.

Generally, the production method or structure of plate-shaped reinforced concrete W, as shown in Figure 5, is to implant a single layer or several layers of vertically and horizontally interlaced steel mesh 3 in the formwork of the component according to the thickness of the plate before pouring concrete. After injecting concrete, it is obvious that the reinforced concrete plate member made in this way is a whole entity, so it will consume a large amount of steel bars and concrete, and its biggest disadvantage is that the whole member will become very heavy and heavy. The hoisting, carrying, and installation of the component will cause construction troubles.

As we know, the most important requirements for the external wall of a building are earthquake resistance, wind resistance, waterproof and heat insulation, and the strength only needs to be able to support its own weight and external force. If the weight is too large, it will be a bad load on the structure Therefore, in addition to the supporting force, strength, and wind resistance of the reinforced concrete exterior wall, if the weight is too heavy, it will become a failure. And when using this structure, heat insulation or sound insulation cotton can be built into the groove of the thin plate to enhance the effect of soundproofing and heat insulation. In addition, reducing the amount of concrete can not only reduce the weight but also be more environmentally friendly.

Based on this, it can be understood that a precast wall panel with sufficient strength and reduced weight is a good exterior wall structure. Therefore, our company has learned from years of experience in construction and construction that many reinforced concrete panels or wall panels should be aimed at maintaining strength. Under the condition of lowering the weight and strengthening the sound insulation, heat insulation and environmental protection as the goal, the utility model developed the utility model "lightweight precast concrete wall panel or plate".

Contents of the invention

The main concept of the utility model is to provide a precast concrete wall panel, floor slab or plate that can significantly reduce weight and maintain its strength. It designs the reinforced concrete wall panel or plate to have a groove that reduces the volume of concrete, and constructs equidistant Construct the reinforced rib, its structure is to lay steel mesh on the bottom of the component, and implant a triangular steel frame or a continuous spiral stirrup through the main steel bar in the reinforced rib, and finally pour concrete, it is said that the wall board or plate is well obtained. Strength, reduce weight, and make the production and construction more simplified and completed quickly.

Detailed ways

As shown in Figure 1, the utility model is equipped with end steel molds 1 and 2 on the periphery of the precast structural member, and its inner edge is provided with lap grooves 11 and 21, and the bottom layer between the steel molds 1 and 2 at both ends is laid with vertical and transverse The reinforced mesh 3 is provided with a triangular steel frame 4 at an appropriate position, and a saddle-shaped steel bar 5 passing through the triangular steel frame 4 and implanted in the bottom of the reinforced mesh 3 is used, and a ladder formwork 6 is placed on the top of the triangular steel frame 4. After the concrete is poured twice, it is poured to the bottom edge of the trapezoidal formwork 6 for the first time, and then it is filled after solidification. In this way, the reinforced concrete wallboard or plate can be made into a groove with reduced concrete volume. And form the reinforcing ribs with appropriate distance, so that the wallboard or plate has good strength, lighten the weight, and make the production and construction more simplified and fast, and can be installed in the groove between the aforementioned strengthening ribs, and add heat insulation, Sound insulation cotton, in order to provide enhanced heat insulation and sound insulation performance, and obtain better functionality.

If this utility model is intended to be used as an exterior wall panel of a building, as shown in Fig. 2, it can be laid with rubber molds 31 and exterior decorative materials, such as magnetic tiles 32, at the bottom of the steel molds 1 and 2 at both ends. , so that when the wallboard is poured into the concrete, the concrete is used to include and combine the tiles 32 at the same time.

As shown in Figure 2, the triangular steel bar frame 4 implanted in the reinforcing rib of the above-mentioned utility model member can also be implanted with a steel mesh, and its structure is a continuous spiral stirrup 7 with several main steel bars 71 running through the periphery. , and can obtain a more rapid production construction structure.

However, in the above-mentioned wallboard or plate structure of the present invention, it must be achieved by secondary pouring of concrete. In order to shorten the production and construction, as shown in Figure 3, the ladder formwork 6 can be reversely placed at the bottom. Place the steel mesh 3, the triangular steel frame 4 or the continuous spiral stirrup 7 running through the main steel bar 71 in the upper position in reverse, and then it can be formed by the construction method of pouring concrete once, and the magnetic tile 32 on the outside of the structure is preformed Apply later.
