Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding construction, and particularly relates to a wall connecting member structure and a wall connecting system. Background Technique

[0002] During the construction process, in some working conditions, it is necessary to erect a scaffolding outside the building. To ensure the stability of the scaffolding and prevent it from peeling off and collapsing towards the outside of the building, it is necessary to set up wall connecting members between the scaffolding and the building for tensioning; in the current general solution, the wall connecting members are embedded in the beam body of the building, which requires occupying the upper space of the beam body, and affects the subsequent masonry and decoration construction of the upper wall of the beam body after connection.

[0003] To solve the above problems, a preferred solution for those skilled in the art is: first carry out wall masonry on the beam body, then drill holes in the wall, and cooperate and fix the wall connecting members with the holes to achieve the purpose of connecting the scaffolding and the building.

[0004] However, in the above solution, during the later use, there will be a certain risk of loosening when the wall connecting member cooperates with the hole. Although the risk of loosening is small, certain safeguard measures are still required to ensure the safety of the connection between the wall connecting member and the building. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the problem that there is a certain risk of loosening when the wall connecting member cooperates with the hole in the background technique, and to provide a wall connecting member structure and a wall connecting system.

[0006] In a first aspect, the utility model provides a wall connecting member structure, comprising:

[0007] A sleeve, on the wall of which a first opening is provided;

[0008] An unfolding mechanism, comprising a first connecting member and at least two latch pins hinged to the first connecting member, and the latch pins can rotate relative to the first connecting member so that at least a part of the latch pins extends out of the sleeve from the first opening.

[0009] The above solution of the utility model can be used in the case of the wall connecting member and the hole, and can also be used as a single component for connecting the scaffolding and the building, and is not limited to the working conditions in the background technique.

[0010] For the wall connecting member structure provided by the utility model, during operation, by pushing the first connecting member, at least a part of the latch pins extends out of the sleeve from the first opening to form a protruding structure for limiting in the length direction of the sleeve.

[0011] Taking some preferred working conditions as examples: For a wall connecting member structure provided by the present utility model, during operation, connection holes can be formed on the wall. After passing the sleeve through the connection holes, the sleeve can be clamped and fixed by extending the pin out of the sleeve. At the same time, connecting the scaffolding to the sleeve can achieve the connection between the scaffolding and the wall, effectively preventing the scaffolding from tipping over. The structure of the present utility model is simple and convenient to use, without the need to set up tie members above the wall, and has little impact on subsequent wall masonry and decoration construction.

[0012] Preferably, the deployment mechanism includes a deployed state and a retracted state:

[0013] In the deployed state, the free end of the pin has a first distance relative to the axis of the sleeve;

[0014] In the retracted state, the free end of the pin has a second distance relative to the axis of the sleeve, and the first distance is greater than the second distance.

[0015] Preferably, a chute is provided on the pin, and a pin shaft slidably matched with the chute is provided on the sleeve. When the first connecting member moves along the axis of the sleeve, the pin can rotate relative to the first connecting member.

[0016] Through the cooperation of the pin shaft and the chute, the movement posture of the pin can be restricted, so that during operation, the switching between the deployed state and the retracted state of the pin can be realized by pushing and pulling the first connecting member, which is flexible and convenient to use.

[0017] Preferably, a threaded head is provided at the first end of the sleeve.

[0018] A threaded sleeve can be correspondingly provided at the installation position. The cooperation between the threaded head and the threaded sleeve can further enhance the tie strength between the sleeve and the wall and reduce the probability of structural failure.

[0019] Preferably, a second opening is provided at the second end of the sleeve. One end of the first connecting member close to the second opening is connected to the second connecting member, and at least part of the second connecting member is located outside the sleeve.

[0020] At least part of the second connecting member is located outside the sleeve, and the operator can move the first connecting member by pushing and pulling the second connecting member, thereby changing the state of the deployment mechanism.

[0021] Preferably, the second connecting member has a first state and a second state:

[0022] In the first state, the axis of the second connecting member is parallel to the axis of the first connecting member;

[0023] In the second state, the axis of the second connecting member is perpendicular to the axis of the first connecting member.

[0024] When rotating the sleeve to screw in the threaded head, the second connecting member is switched to the first state, which can reduce the interference between the second connecting member and the scaffolding and facilitate the screwing in of the sleeve; when pushing or pulling the first connecting member, the second connecting member is switched to the second state. On the one hand, it increases the contact area during pushing, and on the other hand, it provides a handle for pulling out, facilitating the operator to apply force.

[0025] Preferably, a ball head seat is provided at the end of the first connecting member, and a ball head is correspondingly provided at the end of the second connecting member. The ball head is ball-joint connected to the ball head seat.

[0026] Preferably, a relief groove is provided on the ball head seat. The relief groove is configured to: allow the second connecting member to switch between the first state and the second state and be able to snap onto the second connecting member in the second state.

[0027] The shape of the relief groove can be L-shaped.

[0028] Preferably, a limiting notch is provided on the side of the sleeve close to the second opening. The limiting notch can snap onto the second connecting member in the second state.

[0029] The limiting notch can be L-shaped, and one side of it is communicated with the end face of the sleeve. The second connecting member in the second state can extend in from the communication part. After extending to the bottom, by rotating the second connecting member, it can be snapped into the limiting notch, thereby restricting the first connecting member from moving in the direction close to the second end to lock the unfolded state of the unfolding mechanism.

[0032] Preferably, a threaded sleeve is provided on the side of the second connecting hole away from the first connecting hole.

[0033] Compared with the prior art, the beneficial effects of the present utility model are:

[0062] Embodiment 1

[0063] A wall connecting member structure provided in this embodiment includes a sleeve 1 and a deployment mechanism arranged inside the sleeve 1; wherein, a first opening 11 is arranged on the barrel wall of the sleeve 1, and the deployment mechanism includes a first connecting member 13 and at least two latch pins 131. At least two latch pins 131 are hinged to the first connecting member 13, and the latch pins 131 can rotate relative to the first connecting member 13 so that at least a part of the latch pins 131 extends out of the sleeve 1 from the first opening 11.

[0064] In a preferred manner, the sleeve 1 is also called a wall connecting rod under certain working conditions. The sleeve 1 is a hollow structure, including an annular barrel wall and a barrel cavity formed by enclosing the barrel wall. At least a part of the deployment mechanism is installed in the barrel cavity of the sleeve 1; the first opening 11 is arranged on the barrel wall and the number of the first openings 11 is preferably two. At least two latch pins 131 can extend out from the two first openings 11 respectively to achieve deployment, and in the deployed state, the distance from the free end of the latch pin 131 to the axis of the sleeve 1 is greater than the radius of the sleeve 1.

[0065] The deployment mechanism includes a deployed state and a retracted state:

[0066] In the deployed state, the free end of the latch pin 131 has a first distance relative to the axis of the sleeve 1;

[0067] In the retracted state, the free end of the latch pin 131 has a second distance relative to the axis of the sleeve 1, and the first distance is greater than the second distance.

[0068] The first connecting member 13 is used to connect with the latch pins 131. It can be a rod, a block, etc. The first connecting member 13 can be entirely located in the barrel cavity of the sleeve 1 or partially located in the barrel cavity; the hinged connection between the first connecting member 13 and the latch pins 131 enables the latch pins 131 to rotate around the hinge point. Preferably, one end of all the latch pins 131 is hinged to the same point on the first connecting member 13, and the other ends of the latch pins 131 can open away from each other.

[0069] The above solution of the utility model can be used in the case of connecting wall members and openings, and can also be used as a single component for connecting a scaffold and a building. It is not limited to the working conditions in the background technology.

[0070] The utility model provides a wall connecting member structure. When working, by pushing the first connecting member 13, at least a part of the latch 131 extends out of the sleeve 1 from the first opening 11 to form a protruding structure for limiting the length direction of the sleeve 1.

[0071] Taking some preferred working conditions as examples: the utility model provides a wall connecting member structure, which can open a connecting hole on the wall 3 when working. After the sleeve 1 is inserted into the connecting hole, the bayonet 131 is extended out of the sleeve 1 to clamp and fix the sleeve 1, and the scaffold is connected to the sleeve 1 at the same time, so as to realize the connection between the scaffold and the wall 3 and effectively prevent the scaffold from overturning. The utility model has a simple structure and is easy to use. It does not need to set a tie member above the wall 3, and has little impact on the subsequent masonry and decoration construction of the wall 3.

[0072] In one or several preferred embodiments, a slide groove 132 is provided on the bayonet 131, and a pin shaft 133 slidably matched with the slide groove 132 is provided on the sleeve 1. When the first connecting member 13 moves along the axial direction of the sleeve 1, the bayonet 131 can rotate relative to the first connecting member 13.

[0073] like Figure 1-2 As shown, the sliding cooperation between the pin shaft 133 and the slide groove 132 is: the pin shaft 133 is located in the slide groove 132 and can move and rotate relative to the slide groove 132; the pin shaft 133 is fixed to the sleeve 1, and the first connecting member 13 is pushed to move along the axis of the sleeve 1. The latch 131 will rotate around the first connecting member 13 under the restriction of the pin shaft 13, thereby realizing the switching of the deployed or retracted state, which is flexible and convenient to use.

[0074] Example 2

[0075] like Figure 1-5 As shown, this embodiment provides a wall connecting member structure, which is different from Embodiment 1 in that, in this embodiment, a threaded head 15 is provided at the first end of the sleeve 1.

[0076] The threaded head 15 has threads, and a threaded sleeve 16 can be set corresponding to the installation position. When in use, the first end of the sleeve 1 is inserted into the connecting hole and screwed so that it can be threadedly matched with the threaded sleeve 16, which can further enhance the tensile strength between the sleeve 1 and the wall 3, reduce the probability of structural failure, and improve safety.

[0077] Preferably, the thread head 15 has an external thread, and the outer diameter of the thread head 15 is smaller than the outer diameter of the sleeve 1 .

[0078] In one or several preferred embodiments, a second opening 12 is provided at the second end of the sleeve 1. One end of the first connecting member 13 close to the second opening 12 is connected to the second connecting member 14, and at least a part of the second connecting member 14 is located outside the sleeve 1.

[0079] The second end of the sleeve 1 is opposite to the first end, and a second opening 12 communicating with the outside and the barrel cavity is provided at the second end. The first connecting member 13 can extend out of the second opening 12 or not. One end of the first connecting member 13 close to the second opening 12 is connected to the second connecting member 14, and at least a part of the second connecting member 14 is located outside the sleeve 1, so that an operator can move the first connecting member 13 by pushing or pulling the second connecting member 14, thereby changing the state of the unfolding mechanism.

[0080] Both the first connecting member 13 and the second connecting member 14 can be rods, and a support member can be provided in the barrel cavity of the sleeve 1 to limit the position of the first connecting member 13. Preferably, the first connecting member 13 is located on the axis of the sleeve 1, and the first connecting member 13 can move along the axis direction of the sleeve 1.

[0081] Preferably, the second connecting member 14 has a first state and a second state:

[0082] In the first state, the axis of the second connecting member 14 is parallel to the axis of the first connecting member 13;

[0083] In the second state, the axis of the second connecting member 14 is perpendicular to the axis of the first connecting member 13.

[0084] When the sleeve 1 is rotated to screw the threaded head 15 into the threaded sleeve 16, the second connecting member 14 can be switched to the first state. At this time, the axis of the second connecting member 14 is parallel to the axis of the first connecting member 13. The rotation of the sleeve 1 around its axis does not occupy extra space and is not likely to interfere with the scaffolding. When the first connecting member 13 is pushed or pulled to switch the state of the unfolding mechanism, the second connecting member 14 can be switched to the second state. At this time, the side of the second connecting member 14 can be used as a force application point to push the first connecting member 13 or as a handle to pull out the first connecting member 13, which is convenient for the operator to use.

[0085] Optionally, the first connecting member 13 and the second connecting member 14 can be hinged or ball-jointed. Preferably, as Figure 3-4 shown, a ball head seat 2 is provided at the end of the first connecting member 13, and a ball head 21 is correspondingly provided at the end of the second connecting member 14. The ball head 21 is ball-jointed with the ball head seat 2.

[0086] Further preferably, a relief groove 22 is provided on the ball head seat 2. The relief groove 22 is configured to: allow the second connecting member 14 to switch between the first state and the second state, and be able to snap onto the second connecting member 14 in the second state.

[0087] The relief groove 22 can be an L-shaped groove provided on the ball head seat 2. The periphery of the relief groove 22 is defined by the housing of the ball head seat 2. The ball head 21 at the end of the second connecting member 14 is placed into the ball head seat 2, and the second connecting member 14 extends out from the relief groove 22. Due to the restriction of the housing on the ball head seat 2, the second connecting member 14 can only move along the direction of the opening of the relief groove 22. The shape of the opening of the relief groove 22 can be similar to an L shape. One side is used for the second connecting member 14 to switch between the first state and the second state, and the other side can be used to clamp the second connecting member 14 to lock it in the second state.

[0088] If the second connecting member 14 is to be switched from the first state to the locked second state, the second connecting member 14 can be first pulled to be perpendicular to the first connecting member 13, and then the second connecting member 14 can be pushed to rotate a small distance around the axis of the first connecting member 13. If the second connecting member 14 is to be switched from the locked second state to the first state, the reverse operation can be performed.

[0089] In one or several preferred embodiments, as Figure 5 shown, a limiting notch 121 is provided on one side of the sleeve 1 close to the second opening 12. The limiting notch 121 can clamp the second connecting member 14 in the second state.

[0090] This limiting notch 121 can also be called a limiting groove. Its shape can be an L shape. One side of the limiting notch 121 communicates with the end face of the sleeve 1. The second connecting member 14 in the second state can extend in from this communication part. After extending to the bottom, by rotating the second connecting member 14, it can be clamped to the other side of the limiting notch 121, thereby restricting the first connecting member 13 from moving towards the direction close to the second end to lock the deployed state of the deployment mechanism.

[0092] A wall connecting system provided in this embodiment includes a wall body 3 and a wall connecting member structure as described in Embodiment 1 or 2, wherein: a first connecting hole 31 and a second connecting hole 32 that are connected are opened on the wall body 3, and the aperture of the second connecting hole 32 is larger than that of the first connecting hole 31; at least part of the sleeve 1 extends into the first connecting hole 31 and the second connecting hole 32, and the pin 131 is clamped in the second connecting hole 32.

[0093] In the axial direction of the first connecting hole 31, the projection of the first connecting hole 31 is located within the projection range of the second connecting hole 32, and preferably, the axis of the first connecting hole 31 is collinear with the axis of the second connecting hole 32.

[0094] A wall connection system provided by the present utility model can simply and conveniently arrange wall connectors on the wall 3 for connection with the scaffolding due to the use of the wall connector structure as described above, thereby preventing the scaffolding from tipping over and reducing the impact on the subsequent masonry and decoration construction of the wall 3.

[0095] In one or several preferred embodiments, a threaded sleeve 16 is provided on the side of the second connection hole 32 away from the first connection hole 31.

[0096] As Figure 6 shown, a third connection hole 33 can be arranged on the side of the second connection hole 32 away from the first connection hole 31, and the threaded sleeve 16 can be snap-connected to the end of the third connection hole 33 for mating connection with the threaded head 15 at the end of the sleeve 1.

[0097] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
