Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to an environmentally friendly concrete prefabricated component. Background Art

[0002] Engineering composite materials that are made by bonding aggregates into a whole by cementitious materials are collectively referred to as concrete. Concrete is one of the most important civil engineering materials in contemporary times. It has the characteristics of abundant raw materials, low price and simple production process. When producing and processing concrete, people will use precast concrete components to stir and mix the concrete raw materials. When using existing precast concrete components, the operation steps are simple and the mixing effect is relatively ideal, but there are still many inconveniences.

[0003] Nowadays, most buildings are constructed with cast-in-place concrete structures and prefabricated external wall panels. Although their overall performance is good, the building prefabrication rate is low. Some prefabricated components use mortise and tenon connection structures for easy connection. Due to insufficient strength requirements, they are prone to breakage during transportation, resulting in reduced economic benefits. The fixed connection structure leads to large installation limitations, affecting on-site construction efficiency. Utility Model Content

[0004] In order to solve the above technical problems, an environmentally friendly prefabricated concrete component is provided.

The prefabricated component body is composed of two concrete wall panel layers and a reinforcing component plate arranged between the concrete wall panel layers. The concrete wall panel layers and the reinforcing component plates are fixedly connected in pairs. The end surfaces of the reinforcing component plates and the concrete wall panel layers form groove connecting parts around the prefabricated component body. The prefabricated component body is provided with a through fixing hole at the groove connecting part, and is fixedly connected to the connecting member by connecting bolts.

[0006] Furthermore, the connecting member is an axisymmetric structure, and the half-side structure is clamped in the groove connecting part. The connecting member is provided with a ramp structure matching the inner contour of the groove connecting part, and the ramp structure is provided with a positioning boss.

[0007] Furthermore, positioning holes located in the groove connection portion are arranged around the reinforcing member plate, and the positioning holes correspond to the positions of the positioning bosses on the connecting member.

[0008] Furthermore, the positioning boss and the positioning hole are conical structures, and the height of the positioning boss is smaller than the depth of the positioning hole.

[0009] Furthermore, a composite board layer is arranged on the surface of the reinforcing member plate, a mortar layer is poured inside the composite board layer, and a horizontal steel bar structure is arranged inside the mortar layer.

[0010] Furthermore, a reinforcement column with a length greater than the thickness of the reinforcement component plate is arranged inside the reinforcement component plate, and a protrusion is arranged on the surface of the reinforcement component plate.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0019] An embodiment of the utility model, as Figure 1 and Figure 2As shown, the prefabricated component body 1 is composed of two concrete wall panel layers 11 and a reinforcing component plate 12 arranged between the concrete wall panel layers 11. The concrete wall panel layers 11 and the reinforcing component plates 12 are fixedly connected in pairs. The end surfaces of the reinforcing component plates 12 and the concrete wall panel layers 11 form a groove connection part 3 around the prefabricated component body 1. The prefabricated component body 1 is provided with a through fixing hole 4 at the groove connection part 3, and is fixedly connected to the connecting member 2 by a connecting bolt. The surface of the through fixing hole 4 is provided with a countersunk hole. After the connecting bolt is locked, the nut is located in the countersunk hole to avoid affecting the surface flatness. As a preferred embodiment of the present application, the countersunk hole shape of the through fixing hole 4 at the bottom is set to a hexagonal shape for clamping the fixing nut. The present application greatly improves the structural strength of the prefabricated component through the multi-layer structural plate and the strengthening column arranged along the thickness direction. The installation is simple, the overall construction period is shortened, the amount of manual work is reduced, and the multiple pollution such as arc light, smoke, and odor at the construction site can be reduced, which is green and environmentally friendly.

[0020] The connecting member 2 is an axisymmetric structure, and half of the structure is clamped in the groove connecting part 3. The connecting member 2 is provided with a ramp structure that matches the inner contour of the groove connecting part 3. The ramp structure is provided with a positioning boss 21. Compared with the traditional straight-plug structure, the ramp structure is more convenient and labor-saving in installation, has quick positioning, and improves on-site construction efficiency.

[0021] The reinforcing member plate 12 is provided with positioning holes 5 located in the groove connecting part 3 around it, and the positioning holes 5 correspond to the positions of the positioning bosses 21 on the connecting member 2. When two prefabricated members need to be connected, the connecting member is inserted into the groove connecting part 3 at the corresponding position, and the positioning bosses 21 are aligned and inserted into the positioning holes 5 to achieve positioning, and the locking is completed by connecting bolts.

[0022] The positioning boss 21 and the positioning hole 5 are of a conical structure, which reduces the difficulty of installation and improves the installation efficiency. The height of the positioning boss 21 is less than the depth of the positioning hole 5 to avoid the positioning boss height being too high to affect the fit of the connection surface of the prefabricated component.

[0023] A composite board layer 123 is arranged on the surface of the reinforcing component plate 12, a mortar layer 121 is poured inside the composite board layer 123, and a horizontal steel structure 122 is arranged inside the mortar layer 121. The composite board layer 123 has the advantages of thermal insulation, earthquake resistance and fire prevention, lightweight sound insulation, and recyclability. The thermal insulation characteristics of the mortar layer 121 can further improve the thermal insulation and sound insulation and fire prevention performance of the prefabricated component body 1. The steel structure 122 can improve the strength of the prefabricated component body 1.

[0024] A reinforcing column 6 whose length is greater than the thickness of the reinforcing component plate 12 is arranged inside the reinforcing component plate 12. The reinforcing column 6 is provided with a protrusion on the surface of the reinforcing component plate 12 to increase the structural strength of the prefabricated component body 1 in the thickness direction and prevent breakage due to bumps during transportation due to insufficient strength.

[0025] A positioning groove 7 is provided on the inner side of the reinforcement column 6 corresponding to the concrete wall panel layer 11. During the process of connecting and fixing the concrete wall panel layer 11 and the reinforcement member plate 12, rapid positioning is achieved through the positioning groove 7 and the reinforcement column 6, thereby improving production efficiency.
