Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated wall connection or wall column connection in the construction process, specifically a wall connector. Background Technology

[0002] Precast concrete is poured elsewhere, not on the final construction site. In recent years, precast concrete has become a new favorite in the construction industry due to its low cost and excellent performance. Its wide variety of styles, weight, and excellent flexural strength and performance have led to its widespread use in road barriers, water storage tanks, exterior walls, building construction, and decoration.

[0003] The connection technology of precast concrete components has a significant impact on the quality of buildings and construction efficiency. For example, in the construction of highways, municipal works, and railway bridges, the existing concrete is often used as the load-bearing point of the external support, and is connected to the external support, steel formwork, etc.

[0004] Currently, the connection between precast concrete components (such as precast concrete walls) and external supports and other components is mostly achieved using connecting steel ropes with anchor rings at both ends. The connection method involves embedding an anchor ring within the precast concrete and then welding the exposed anchor ring to the external supports and other components to ultimately connect the precast concrete component and the external supports into a single unit. For example, patent publication number CN214614887U discloses a connection node between a precast floor slab and a precast wall panel in a bathroom, which uses steel wire rope anchor rings for fixation, strengthening the overall connection between the precast floor slab and the precast wall panel. However, existing steel wire rope anchor rings of this type have the following problems:

[0005] 1. Because the overall thickness of the steel reinforcement rope is small, multiple steel reinforcement ropes need to be used at intervals on one wall. When multiple steel reinforcement ropes are used, it is impossible to guarantee the straightness of each steel reinforcement rope during installation, which can easily lead to unevenness. If the installation height of the steel reinforcement ropes is different, it will be easy to have difficulty connecting them to another precast concrete component later, which will undoubtedly prolong the installation time.

[0006] 2. When using steel ropes for connection, since both ends of the steel ropes are anchor rings, and the anchor rings are tubular and have smooth surfaces, the connection strength between them and the interior of the precast concrete is poor in the later stages. This can easily lead to the anchor rings detaching from the cement, ultimately affecting the overall connection strength.

[0007] In summary, the current steel reinforcement ropes used in precast concrete components have problems such as poor bonding strength with cement in the later stages, easy detachment, uneven installation height when multiple steel reinforcement ropes are installed, and long installation time. Utility Model Content

[0008] The purpose of this utility model is to provide a wall connector to solve the problems mentioned in the background art, such as poor strength of the connection between the steel rope and cement in the later stage, easy detachment, uneven installation height when multiple steel ropes are installed, and long installation time.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a wall connector, comprising a connecting body, the connecting body being a long strip structure, with a V-shaped guide groove extending along the length of the connecting body on both the front and rear sides, the two V-shaped guide grooves being mirror images of each other, one or more steel ropes spaced apart inside the connecting body, a horizontally arranged limiting ring and a vertically arranged steel support for the steel ropes, one or more limiting through holes at the bottom of the connecting body, each steel support passing through a corresponding limiting through hole, and an anchor ring at the lower end of each steel support, two "7"-shaped hooks on the side of each limiting through hole, the two "7"-shaped hooks on the same limiting through hole being mirror images and forming a slot, a limiting seat being inserted into each slot, and a limiting block being provided on the side of the limiting seat, the limiting block being able to be inserted into the gap of the steel support and used to limit the steel rope into the connecting body.

[0010] Preferably, in order to further improve the limiting effect, the steel bar support includes two support rods distributed front and rear, with a gap between the two support rods forming the gap, and a locking groove that cooperates with the support rod is provided on the side of the limiting block.

[0011] Preferably, the connecting body includes a long box and a top cover. The long box has openings at the top and on both the front and back sides. The top cover covers the long box and closes the front and back openings and the top opening of the long box.

[0012] Preferably, to improve the connection strength in the later stage, the front and rear of the connecting body are provided with lifting plates integrally formed with the connecting body, and the lifting plates extend along the length direction of the connecting body.

[0013] Preferably, to further improve the connection strength in the later stage, the lifting plate has a U-shaped structure, and the U-shaped opening of the lifting plate is connected to the connecting body.

[0014] As a preferred option, to ensure a larger contact area between the structure and the cement and a higher connection strength in the later stage, the elongated box body includes an upper half and a lower half. The upper half is trapezoidal in shape, and the lower half is square in shape. Two V-shaped guide grooves are located between the upper half and the lower half.

[0015] As a preferred embodiment, to further achieve the locking function, the two sides of the limiting ring abut against the inner wall of the connecting body.

[0016] Preferably, the connecting body has one or more circular grooves on both the front and rear sides.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This structural design enables all steel ropes to maintain a consistent installation height after installation, resulting in better straightness of multiple steel ropes, facilitating subsequent installation, and further reducing installation time. Furthermore, the aforementioned structural design makes it easier to thread the steel ropes. During subsequent installation, the part with the connecting body is first inserted into the precast concrete frame, and then cement is poured into the precast concrete frame. At this time, the V-shaped guide grooves on both sides of the connecting body allow the cement to quickly spread around the entire connecting body, enabling better adhesion between the connecting body and the cement. The larger contact area between the connecting body and the cement ultimately improves the connection strength between the connector and the precast concrete component. Moreover, the strip-shaped connecting body allows for better adaptation and connection with the precast concrete component. Attached Figure Description

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Example 1:

[0031] Please see Figure 1-10 This embodiment discloses a wall connector, including a connecting body 1, which is a long strip structure. A V-shaped guide groove 2 extending along the length of the connecting body 1 is provided on both the front and rear sides of the connecting body 1. The two V-shaped guide grooves 2 are arranged mirror images of each other. One or more steel reinforcing ropes 3 are spaced apart inside the connecting body 1. The steel reinforcing ropes 3 include horizontally arranged limiting rings 301 and vertically arranged steel reinforcing support brackets 302. One or more limiting through holes 4 are provided at the bottom of the connecting body 1. Each steel reinforcing support... A corresponding limiting through hole 4 passes through the bottom of 302, and an anchor ring 5 is provided at the lower end of each steel bar support 302. Two “7”-shaped hooks 6 are provided on the side of each limiting through hole 4. The two “7”-shaped hooks 6 on the same limiting through hole 4 are mirrored and form a slot. A limiting seat 8 is inserted into each slot. A limiting block 801 is provided on the side of the limiting seat 8. The limiting block 801 can be inserted into the gap 3022 of the steel bar support 302 and is used to limit the steel bar rope 3 to the connecting body 1.

[0032] Preferably, in order to further improve the limiting effect, the steel bar support 302 includes two support rods 3021 distributed front and rear, and there is a gap between the two support rods 3021 to form the gap 3022. A locking groove 303 that cooperates with the support rods 3021 is provided on the side of the limiting block 801.

[0033] Preferably, the connecting body 1 includes a long box body 101 and an upper cover plate 102. The long box body 101 has openings at the top and on both the front and rear sides. The upper cover plate 102 covers the long box body 101 and is used to close the front and rear openings and the top opening of the long box body 101. In this embodiment, the upper cover plate 102 and the long box body 101 are fixed by welding.

[0034] Preferably, to improve the later connection strength, the front and rear of the connecting body 1 are provided with lifting plates 9 integrally formed with the connecting body 1. The lifting plates 9 extend along the length direction of the connecting body 1 to further improve the later connection strength. The lifting plates 9 have a U-shaped structure, and the U-shaped opening of the lifting plates 9 is connected to the connecting body 1. In this embodiment, by setting the lifting plates 9 in two layers, the overall hardness of the upper surface of the connecting body is ensured to be stronger, which further improves the later connection strength.

[0035] Preferably, to ensure a larger contact area between the structure and cement and higher subsequent connection strength, the elongated box 101 includes an upper half 1011 and a lower half 1012. The upper half 1011 is trapezoidal in shape, and the lower half 1012 is square in shape. Two V-shaped guide grooves 2 are located between the upper half 1011 and the lower half 1012. Through the above structural arrangement, the elongated box 101 is set in a form that is larger at the top and smaller at the bottom. When the device is finally placed in the precast concrete frame, cement is poured into the precast concrete frame, which further increases the contact area between the cement and the outer surface of the elongated box 101, thereby improving the subsequent connection strength.

[0036] As a preferred embodiment, to further achieve the locking function, the two sides of the limiting ring 301 abut against the inner wall of the connecting body 1. By setting the limiting ring 301 against the inner wall of the connecting body 1, the entire steel rope 3 can be further clamped. Moreover, the connecting body 1 has one or more circular grooves 7 on both the front and rear sides. In this embodiment, by setting multiple circular grooves 7 on the front and rear sides, when the precast concrete component is poured into the precast concrete frame, the cement can fill into the circular grooves 7, further increasing the contact area between the cement and the outer surface of the device, thereby improving the connection strength in the later stage.

[0037] This structure uses a long, narrow connecting body 1. Several steel reinforcing ropes 3 are spaced apart within the connecting body 1. Each steel reinforcing rope 3 passes through a corresponding limiting through-hole 4 in the connecting body 1. A slot is formed on the side of the limiting through-hole 4 by two mirror-image "7"-shaped hooks 6. A limiting seat 8, passing through a steel reinforcing bracket 302 and positioned within the gap 3022 of the steel reinforcing bracket 302, is inserted into each slot to fix the steel reinforcing rope 3. Once all the steel reinforcing ropes 3 are installed, their installation height is consistent, resulting in better straightness and easier subsequent installation, further reducing installation time. This structural design also makes it easier to thread the steel reinforcing ropes 3. Furthermore, during subsequent installation, the connecting body 1 is first... Partially inserted into the precast concrete frame, cement is then poured into the precast concrete frame. At this time, under the action of the V-shaped guide grooves 2 on both sides of the connecting body 1, the cement can quickly cover the entire area around the connecting body 1, so that the entire connecting body 1 can better bond with the cement. The contact area between the connecting body 1 and the cement is larger, which ultimately improves the connection strength between the connector and the interior of the precast concrete component. Moreover, since the connection with the precast concrete adopts a strip-shaped connecting body 1, it can better adapt to the precast concrete component. In addition, when the exterior wall surface is too large and multiple units are needed, multiple units can be welded together in sequence to ensure that all steel ropes 3 are installed at the same height. At the same time, the installation range of this structure is wide and it is simple to install.
