Description

Technical Field

[0001] This utility model relates to the field of precast concrete wall panel technology, and in particular to an assemblable precast concrete wall panel. Background Technology

[0002] Precast concrete wall panels are concrete wall panels that are prefabricated in a factory and then transported to the construction site for assembly. Traditional precast concrete wall panel connections often use grouting sleeves or bolts, which are cumbersome, time-consuming, and result in low installation efficiency and significant impact on the construction schedule. Therefore, there is an urgent need to develop an assembly-ready precast concrete wall panel that is easy to connect and assemble, reduces construction time, and improves installation efficiency to overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this utility model is to provide an assemblable precast concrete wall panel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An assemblable precast concrete wall panel includes a concrete wall panel, a reinforcing steel frame, connecting wedges, and locking sleeves. The reinforcing steel frame is fixed inside the concrete wall panel. Each of the four sides of the concrete wall panel has a wedge-shaped groove, and the reinforcing steel frame is exposed at the wedge-shaped grooves. The wedge-shaped grooves are used to install the connecting wedges. The bottom of the connecting wedges has two grooves, and each groove has a locking sleeve fixed in it. The bottom of the locking sleeve has a notch, the width of which is smaller than the diameter of the reinforcing steel in the reinforcing steel frame. The notch is used for the reinforcing steel to pass through. The locking sleeve is made of spring steel.

[0005] Preferably, the bottom of the card release mechanism has two guide plates fixed, and the guide plates are inclined outward.

[0006] Preferably, the concrete wall panel is made of C40 high-strength concrete.

[0007] Preferably, the diameter of the reinforcing bars in the reinforcing bar cage 2 is 14mm.

[0008] The beneficial effects of this utility model are as follows: When assembling this precast concrete wall panel, first align two concrete wall panels together. Then, press the connecting wedge into the wedge-shaped grooves on the two concrete wall panels. During the pressing process, the notch of the locking sleeve gradually contacts the reinforcing steel skeleton. Guided by the guide plate, the notch is gradually opened by the reinforcing steel skeleton. When the connecting wedge is pressed into place, the reinforcing steel skeleton is fully inserted into the locking sleeve, which locks the reinforcing steel skeleton in place. The connecting wedge restricts the vertical and horizontal movement of the concrete wall panel, while the locking sleeve and the reinforcing steel skeleton restrict the front-back position of the concrete wall panel, thus splicing two concrete wall panels together. Multiple concrete wall panels can be spliced ​​together in this manner. In summary, this utility model facilitates mutual assembly and connection, reduces construction time, and improves installation efficiency. Attached Figure Description

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] See Figures 1-6 In this embodiment of the present invention, an assemblable precast concrete wall panel includes a concrete wall panel 1, a reinforcing steel frame 2, connecting wedges 3, and a locking sleeve 4. The reinforcing steel frame 2 is fixed inside the concrete wall panel 1. The concrete wall panel 1 is cast using a mold, and the reinforcing steel frame 2 is placed directly into the concrete during casting. After the concrete solidifies, the concrete wall panel 1 and the reinforcing steel frame 2 are fixed together. Each of the four sides of the concrete wall panel 1 is provided with a wedge-shaped groove 101, and the reinforcing steel frame 2 is exposed at the wedge-shaped groove 101. The wedge-shaped groove 101 is used to install the connecting wedges 3, and the bottom of the connecting wedges 3 is provided with two grooves 3. 01. Each groove 301 has a locking sleeve 4 fixed inside. The connecting wedge 3 is cast using a mold, and one end of the locking sleeve 4 is directly inserted into the concrete during casting. After the concrete solidifies, the connecting wedge 3 and the locking sleeve 4 will be fixed together. The bottom of the locking sleeve 4 is provided with a notch 401. The width of the notch 401 is smaller than the diameter of the steel bar on the steel reinforcement skeleton 2. The notch 401 is used for the steel bar to pass through. The bottom of the locking sleeve 4 is fixed with two guide plates 402. The guide plates 402 are inclined outward. The locking sleeve 4 is made of spring steel, which gives it good strength and a certain elastic deformation capacity.

[0019] The diameter of the reinforcing bars in the steel reinforcement cage 2 is 14mm.

[0020] The concrete wall panel 1 is made of C40 high-strength concrete.

[0021] Working principle: During assembly, two precast concrete wall panels 1 are first aligned together. Then, the connecting wedge 3 is pressed into the wedge grooves 101 on the two concrete wall panels 1. During the pressing process, the notch 401 of the locking sleeve 4 gradually contacts the reinforcing steel skeleton 2. The guide plate 402 guides the reinforcing steel skeleton 2, and the notch 401 is gradually opened by the reinforcing steel skeleton 2. When the connecting wedge 3 is pressed into place, the reinforcing steel skeleton 2 is completely inserted into the locking sleeve 4. The locking sleeve 4 locks the reinforcing steel skeleton 2. The connecting wedge 3 restricts the vertical and horizontal movement of the concrete wall panel 1, and the locking sleeve 4 and the reinforcing steel skeleton 2 restrict the front and back position of the concrete wall panel 1, thereby splicing two concrete wall panels 1 together. Multiple concrete wall panels 1 can be spliced ​​together by operating in this way.

[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
