Description

Technical Field

[0001] The utility model relates to a connection between assembled building modules, in particular to an inter-module splicing latch capable of adaptively adjusting installation gaps. Background Art

[0002] A modular building is a whole structure made up of multiple modular units. A fast and reliable inter-module connection method between modular units is key to leveraging the advantages of modular construction and ensuring the overall stability and seismic performance of the structure. This has a significant impact on the promotion and application of modular structures. Currently, the connection methods used in modular structures suffer from problems such as low construction efficiency, easy damage to pre-finished structures, and inconvenient construction in node areas. For example, concrete modular buildings use post-casting or large-scale grouting methods at the construction site, which greatly limits the advantages of rapid construction of modular buildings and makes the pouring quality difficult to control. Welding connections used at the construction site are prone to brittle failure at the joints, have poor energy consumption and deformation capacity, and are significantly affected by the environment and worker skills. At the same time, a large amount of residual stress affects the safety of the connection, making it difficult to detect and control the construction quality of the connection area. Utility Model Content

[0003] The technical problem to be solved by the present invention is that, in view of the deficiencies in the connection between prefabricated building modules, the present invention provides an inter-module splicing latch that can adaptively adjust the installation gap, so as to achieve rapid assembly between modules without affecting the non-structural components of adjacent modules.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A module splicing latch capable of adaptively adjusting installation gaps, the structural features of which include:

[0006] A lock box is embedded in the connection end of the first module, and the lock box includes a box body, a spring, and a lock element. One end of the spring is connected to the lock element, and the other end is connected to the box body. The lock element has a lock catch.

[0007] A plug-in having a lock head at one end and a first connecting structure at the other end, wherein the lock head is used to be inserted into the lock box and locked with the lock buckle;

[0008] A connecting rod, one end of which is used to connect to the connecting end of the second module, and the other end of which is connected to the first connecting structure of the plug-in.

[0009] When the utility model is used, a lock box can be embedded in the connection end of the first module and a connection sleeve can be embedded in the connection end of the second module during production. At the construction site, a connecting rod can be installed in the connecting sleeve, and a plug-in can be installed on the connecting rod. When the first and second modules are hoisted and connected, the modules are spliced together through the self-locking of the plug-in and the lock box, thereby realizing rapid assembly between modules without affecting the non-structural components of the pre-decorated module units.

[0010] Furthermore, the locking elements are symmetrically arranged in the lock box, the lock buckles are arranged opposite to each other on the two locking elements, and the springs are respectively installed between the back sides of the two locking elements and the box body, so that the lock head can be more reliably connected to the lock buckles, and the connection between adjacent modules is more stable and reliable.

[0011] Furthermore, the locking head of the plug-in is inserted between the two locking members and passes over the two lock buckles to form a locked connection with the two lock buckles.

[0012] Furthermore, the first connection structure is an internal thread arranged in the plug-in unit, and the connection rod is a screw rod, which is threadedly connected to the internal thread.

[0013] Furthermore, the plug-in is provided with an axial through-hole, the internal thread is arranged at one end of the through-hole, and the screw rod is provided with an axial hexagonal hole. The through-hole and the hexagonal hole are arranged coaxially, and the aperture of the through-hole is not less than the aperture of the hexagonal hole. In this way, the utility model can adjust the installation height and angle of the plug-in by inserting an hexagonal wrench into the hexagonal hole through the through-hole, so that the installation height and angle of the plug-in at the same joint are consistent.

[0014] Furthermore, the box body, spring, lock, plug-in unit and connecting rod are all made of steel.

[0015] Furthermore, both ends of the locking member are respectively loosely fitted with the box body, and both ends of the locking member are respectively provided with rounded corners to improve the smoothness of insertion and protect the box body.

[0016] Furthermore, the lock head is semi-cylindrical, and the lock buckle has an arc surface matching the semi-cylindrical shape.

[0017] Furthermore, the box body is connected to the steel frame in the first module by welding.

[0018] Furthermore, one end of the connecting rod is threadedly connected to the second module, and the other end is threadedly connected to the plug-in.

[0019] Furthermore, both ends of the spring in the lock box are respectively welded to the inner surface of the lock box and the lock element.

[0020] Furthermore, one end of the connecting rod is screwed to the screw hole of the connecting sleeve embedded on the second module, and the other end is screwed to the plug-in through a thread.

[0021] Furthermore, at the construction site, the screw is first inserted into the reserved screw hole on the module and tightened, and then the plug-in is tightened and connected with the screw, and finally the upper module unit falls down to automatically complete the splicing between modules.

[0022] Furthermore, the size of the plug-in is smaller than the size between the two locks in the lock box. By cooperating with the through hole in the plug-in and the hexagonal hole in the connecting rod, the height of the plug-in can be made consistent, and the angle of the plug-in and the lock box can be consistent, compensating for processing and construction errors.

[0023] Furthermore, the stress-bearing performance of the joints can be improved by adjusting the dimensions of the latch structure.

[0024] Furthermore, the stress-bearing performance of the overall structure can be improved by adjusting the position and number of the latches.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) The modules are connected in a fully dry manner, which is efficient and fast: adjacent modules are connected through lock boxes and plug-ins, eliminating the need for on-site wet operations such as post-pouring and grouting, thereby improving module construction efficiency.

[0027] (2) On-site construction does not damage the pre-decoration in the module unit: the lock box is built into the module, and on-site splicing is achieved by automatically fastening the plug-in and the lock when the modules are stacked, without the need to work inside the module.

[0028] (3) It has the function of compensating for manufacturing and installation errors: the size of the plug-in in the lock box is smaller than the gap between the lock parts, which can improve the production and splicing errors. In addition, the plug-in height can be made consistent by matching the through hole in the plug-in with the hexagonal hole in the connecting rod, and the angle between the plug-in and the lock box is consistent, which improves the sensitivity of installation errors.

[0029] (4) Direct force transmission: The lock box is welded to the steel frame near the module. Under the action of an earthquake, force is directly transmitted between adjacent modules through the lock box at the joint, and the force transmission path is clear.

[0030] (5) Smooth module surface: There are no ribs on the surface of the module unit, and the connecting rods and modules are set independently of each other and connected on site, which makes the module unit more convenient to transport. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the spring 102 is connected to the lock element 103, and the other end is connected to the box body 101. The lock elements 103 are symmetrically arranged in the box body 101. Lock buckles 104 are arranged on two lock elements 103 opposite to each other, and the springs 102 are respectively installed between the back surfaces of the two lock elements 103 and the inner wall surface of the box body 101;

[0044] The plug-in 2 has a locking head 203 at one end and an internal thread 202 at the other end. The locking head 203 is used to be inserted between the two locking buckles 104 in the box body 101 and pass over the two locking buckles 104 to form a locked connection with the two locking buckles 104;

[0045] The connecting rod 3 is preferably a screw rod, one end of which is used for threaded connection with the connecting end of the second module 5, and the other end is threadedly connected with the internal thread 202 of the plug-in 2.

[0046] Furthermore, the insert 2 is provided with an axially extending through hole 201, the internal thread 202 is arranged at one end of the through hole 201, and the screw rod is provided with an axially extending hexagonal hole 301. The through hole 201 and the hexagonal hole 301 are arranged coaxially, and the diameter of the through hole 201 is not less than the diameter of the hexagonal hole 301. In this way, the present invention can adjust the installation height and angle of the insert 2 by inserting an hexagonal wrench through the through hole 201 into the hexagonal hole 301, so that the installation height and angle of the insert 2 at the same joint are consistent.

[0047] In order to ensure the connection strength of the present invention, the box body 101, spring 102, lock 103, plug-in 2 and connecting rod 3 are all made of steel, and the box body 101 is welded to the steel frame in the first module 4, and the two ends of the spring 102 are respectively welded to the inner surface of the box body 101 and the lock 103.

In this way, through rapid assembly, efficient stacking and combination of adjacent module units can be achieved, and finally a modular building with fast construction, high quality, low energy consumption and good economy is formed.

[0050] Furthermore, the size of the plug-in 2 is smaller than the size between the two lock members 103 in the lock box 1.
