A prefabricated concrete wall component

Abstract

This utility model proposes a prefabricated concrete wall component, relating to the field of concrete wall technology. It includes a cement block, a wall panel, and connecting components. The cement block has dovetail-shaped grooves on both sides, an elastic sealing layer on its inner wall, and drainage holes at the bottom. The wall panel has dovetail tenons on both sides and annular grooves on its surface. The connecting components include an adjusting screw, a limiting nut, and an anti-seismic spring. The cement block is fixed to the foundation, and its dovetail-shaped grooves provide vertical limiting (preventing detachment) for the dovetail tenons of the wall panel.

Description

Technical Field

[0001] This utility model relates to the field of concrete wall technology, and in particular to a prefabricated concrete wall component. Background Technology

[0002] Concrete walls are wall structures made of concrete as the core material (usually reinforced with steel bars, fibers, and other reinforcing materials to increase strength) through prefabrication (factory-prefabricated components assembled on-site) or cast-in-place (cast on-site). Relying on the high strength and durability of concrete, they serve as basic components for physical isolation and spatial division. They can be equipped with auxiliary components such as sealing, earthquake resistance, and decoration (e.g., rubber sealing layers, connecting components) as needed, combining structural stability and functional adaptability. They are a common building component that replaces traditional brick and stone walls.

[0003] However, existing prefabricated concrete wall components typically use a structure with grooves on both sides of a central cement pier. The wall panel is inserted into the groove to complete the limiting installation. Relying solely on the groove for limiting, the wall panel and the cement pier are prone to shaking due to external forces (such as earthquakes or wind pressure). Long-term use may lead to loosening of the connection. Water can easily accumulate in the gap between the groove and the wall panel, causing concrete corrosion and reducing structural durability. Therefore, a prefabricated concrete wall component is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated concrete wall component that solves the problems of easy loosening due to external forces and easy water accumulation leading to concrete corrosion in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete wall component, including a cement block, a wall panel, and a connecting component. The cement block has dovetail grooves on both sides, an elastic sealing layer on the inner wall, and drainage holes at the bottom. The wall panel has dovetail tenons on both sides and an annular groove on the surface. The connecting component includes an adjusting screw, a limiting nut, and an anti-vibration spring.

[0006] Preferably, the concrete pier has a pre-embedded steel reinforcement skeleton inside, and pre-embedded steel plates at the top and bottom.

[0007] Preferably, the wall panel is provided with reinforcing ribs inside, and connecting bolts are pre-embedded at the top and bottom.

[0008] Preferably, the adjusting screw passes through a threaded hole in the side wall of the cement block and is connected to a limiting nut on the back.

[0009] Preferably, the anti-seismic spring is sleeved on the adjusting screw and located between the cement block and the wall panel.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The cement block is fixed to the foundation, and its dovetail groove provides vertical restraint (preventing detachment) for the dovetail tenon of the wall panel. When the wall panel is inserted, the elastic sealing layer is squeezed into the groove to seal the gap and prevent water seepage. In the connecting components, the adjusting screw finely adjusts the fit, the anti-vibration spring absorbs vibration and resets, and the limiting nut prevents loosening. At the same time, a small amount of seepage water flows down along the groove and is discharged into the blind ditch through the bottom drainage hole. The components cooperate in sequence to achieve stable installation, anti-vibration sealing and drainage functions. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model relates to a prefabricated concrete wall component, such as... Figure 1-6As shown, it includes a cement block 1. After the cement block 1 is prefabricated, it is fixed to the foundation bolts by the bottom embedded steel plate 15. The two side walls are symmetrically opened with dovetail-shaped grooves 11 along the length of the wall. The inner wall of the groove is reserved with an embedded groove for the elastic sealing layer 12, which serves as the vertical load-bearing component of the wall. The dovetail-shaped grooves 11 provide the installation limit reference for the wall panel 2. The internal embedded steel reinforcement skeleton 14 improves the overall rigidity. The top embedded steel plate 15 can be connected to the transverse pressure beam to enhance the overall stability.

[0021] Furthermore, the wall panel 2 is a precast concrete panel, with precast dovetail tenons 21 on both sides corresponding to the dovetail grooves 11 of the cement block 1; an annular groove 22 is opened on the surface of the tenon along the height direction, and the dovetail tenon 21 of the wall panel 2 is inserted vertically along the dovetail groove 11 of the cement block 1, serving as the main structure of the wall. The mechanical interlocking of the dovetail tenon 21 and the dovetail groove 11 prevents vertical dislodgement and achieves initial fixation; the internal reinforcing ribs 23 enhance the bending strength of the panel and prevent bending deformation during installation or use.

[0022] Furthermore, the elastic sealing layer 12 is a EPDM rubber strip, which is prefabricated and embedded in the inner wall of the dovetail groove 11 of the cement block 1, covering the entire height of the groove. When the wall panel 2 is inserted, the protruding part of the rubber strip is embedded in the annular groove 22 of the dovetail tenon 21, forming a tight fit. The elastic sealing layer 12 is located between the outer surface of the dovetail tenon 21 of the wall panel and the inner wall of the dovetail groove 11 of the cement block 1, in the gap between the two, and in close contact with both, filling the installation gap between the two, preventing rainwater and dust from seeping in through the gap and sealing the effect. At the same time, the elasticity of the rubber absorbs slight vibrations such as small swaying caused by wind, avoiding concrete wear caused by rigid friction between the tenon and the groove.

[0023] Furthermore, the connecting assembly 3 includes an adjusting screw 31, a limiting nut 32, and an anti-seismic spring 33. The adjusting screw 31 passes horizontally through a threaded hole in the side wall of the concrete block 1, with one end extending into the inside of the concrete block 1 towards the wall panel 2, and the other end exposed on the outside of the concrete block 1. The limiting nut 32 is fitted onto the exposed end of the screw and fits against the outer surface of the concrete block 1. The anti-seismic spring 33 is fitted onto the part of the screw located inside the concrete block 1, with one end abutting against the inner wall of the concrete block 1 and the other end abutting against the back of the wall panel 2. It absorbs the vibration energy generated by external forces such as earthquakes and impacts through elastic deformation and resets through elastic restoring force to avoid component cracking caused by rigid collisions.

[0024] Furthermore, drainage holes 13 are opened at the bottom of the dovetail-shaped chute 11 of the cement block 1. One hole is set at the bottom of each chute of each cement block 1, which is connected to the drainage blind ditch around the foundation. It is located below the elastic sealing layer 12 and below the bottom of the dovetail tenon 21. When a small amount of rainwater seeps into the elastic sealing layer 12, such as when the sealing layer is partially worn, the water flows down along the inner wall of the chute and is discharged into the blind ditch through the drainage hole 13, thus preventing water from seeping into the interior of the cement block 1 and causing the steel reinforcement to rust or the bottom of the wall panel 2 to become damp.

[0025] In practical use: the cement block 1 is fixed to the foundation, and its dovetail groove 11 provides vertical limit (prevents detachment) for the dovetail tenon 21 of the wall panel 2. When the wall panel 2 is inserted, the elastic sealing layer 12 is squeezed into the groove to seal the gap and prevent water seepage. In the connecting component 3, the adjusting screw 31 finely adjusts the fit, the anti-vibration spring 33 absorbs vibration and resets, and the limiting nut 32 prevents loosening. At the same time, a small amount of seepage water flows down along the groove and is discharged into the blind ditch through the bottom drainage hole 13. The components cooperate in sequence to achieve stable installation, anti-vibration sealing and drainage functions.
