The embodiment of the present invention provides an overlapping clamping connection assembly 100, including: a connecting member 10, a supporting member 20, and a bridge 40. The connecting member 10 has a first surface and a second surface opposite to each other, and has a mounting hole 11 penetrating through the first surface and the second surface. Taking the orientation in fig. 1 and 2 as an example, the first surface is the upward surface, and the second surface is the downward surface.

Namely, the end of the support base 21 facing downward is provided with a connecting hole 23 for connecting with a fastener. The resilient jaws 22 themselves have resilient properties and are in an open state in the absence of an external force. When the elastic claws 22 extend into the mounting hole 11 from the second surface direction to the first surface direction, the elastic claws 22 are pushed by the mounting hole 11 and are closed. After the elastic claw 22 wears out the mounting hole 11, the received extrusion force disappears, the elastic claw 22 rebounds to the open state, the supporting seat 21 is matched, so that the supporting piece 20 is matched with the mounting hole 11 to be clamped on the connecting piece, the elastic claw 22 is limited on the first surface, the supporting seat 21 is limited on the second surface, an intermediate connection part is arranged between the elastic claw 22 and the supporting seat 21, the intermediate connection part is arranged in the mounting hole 11 in a penetrating manner, and the position between the supporting piece 20 and the connecting piece 10 is fixed. The support base 21 may be coupled to the fastening member through the coupling hole 23 to wrap the fastening member and prevent the fastening member from being exposed.

Further, at least one end of the connecting member 10 is provided with a strap 40, and the strap 40 is at least partially abutted against the second face. The end of the connector 10 provided with the strap 40 may extend beyond the deck plate 200 to be attached to an adjacent deck plate 200.

According to the technical scheme provided by the embodiment of the invention, the supporting piece 20 can be clamped on the connecting piece 10 by matching the elastic clamping claws 22 on the supporting seat 21 with the mounting holes 11 on the connecting piece 10, the structure is simple, the connecting mode is quick and convenient, and the manufacturing efficiency of the clamping type connecting assembly 100 is improved. Simultaneously, see fig. 6, joint formula coupling assembling 100 can be used to connect steel bar truss 300 on floor deck plate body 200, joint formula coupling assembling 100 accessible fastener is connected with floor deck plate body 200, can improve the height of connecting piece 10 through support piece 20, make the concrete change the bottom that gets into connecting piece 10, avoid connecting piece 10 directly to expose and lead to rustting, make the concrete change parcel joint formula coupling assembling 100, avoid connecting piece 10 directly to expose and lead to rustting. Simultaneously, live the fastener parcel through support piece 20, prevent the contact of concrete and fastener, avoid the fastener to be wrapped up by the concrete, reduce the dismantlement degree of difficulty of fastener, improve and dismantle efficiency. In addition, the steel bar truss 300 and the connecting piece 10 can adopt a welding connection mode, and the rigidity of the floor support plate using the clamping connection assembly 100 in the construction stage is increased, so that the deformation of the floor support plate body 200 in the construction stage is reduced, and the floor support plate has a better plate bottom flatness effect.

In addition, adjacent floor support plate body 200 is when the concatenation, the one end that connecting piece 10 was equipped with overlap joint 40 stretches out floor support plate body 200, accessible connecting piece 10 stretches out floor support plate body 200's partial cooperation overlap joint 40 overlap joint on adjacent floor support plate body 200, play the supporting role to it through adjacent floor support plate body 200, when concreting, avoid the splice joint dislocation between two adjacent floor support plate body 200, thereby guarantee the roughness effect of bottom of the floor.

The following examples are presented to further illustrate the invention in conjunction with the detailed description.

In the embodiment of the present invention, the strap 40 is made of, but not limited to, plastic material or rubber material, and is formed by injection molding, so that it will not rust, and thus will not affect the decorative effect of the bottom plate. The connected mode of overlap joint 40 and connecting piece 10 includes the multiple, a realizable mode is, the injection molding of overlap joint 40 is connected in the middle part or the tip of connecting piece 10, be the molten state at the material of moulding plastics under, mould plastics overlap joint 40 at the middle part or the tip of connecting piece 10, make connecting piece 10 compromise through overlap joint 40 and support the effect of two adjacent building carrier plate boards 200, can effectively solve the fissure of displacement problem between two adjacent building carrier plate boards 200 to improve the roughness of building carrier plate bottom.

In order to increase the connection strength between the strap 40 and the connection member 10, another connection method is to provide a strap hole in the middle or the end of the connection member 10, and the strap 40 is inserted through the strap hole and connected to the connection member 10 by injection molding. The strap 40 is partially inserted into the overlapping hole, so that the connection strength between the strap 40 and the connector 10 is increased through the overlapping hole, and the strap 40 is prevented from being separated from the connector 10. If connecting piece 10 one end stretches out floor support plate body 200, then the one end of connecting piece 10 is equipped with the overlap joint hole, if connecting piece 10 both ends all stretch out floor support plate body 200, then the both ends of connecting piece 10 all are equipped with the overlap joint hole to connect overlap joint 40 through the overlap joint hole.

Further, in order to realize the quick connection between the strap 40 and the connector 10 and improve the construction efficiency, the strap 40 is connected to the connector 10 by inserting the strap 40 into the end of the connector 10. After the bridging piece 40 is manufactured by an injection molding tool, a plugging port is reserved on the side surface of the bridging piece 40, the plugging port is plugged at one end of the connecting piece 10, and the size of the plugging port can be slightly smaller than the thickness of the connecting piece 10, so that the connecting piece 10 and the bridging piece 40 can be connected in an interference fit mode.

Further, in order to enhance the stability of the connection between the strap 40 and the concrete, it is achievable that the outer wall of the strap 40 is provided with a convex structure and/or a concave structure. Protruding structure extends along the radial direction of overlap joint 40, and when concreting, protruding structure and sunk structure can be wrapped up to the concrete to further improve the stability of being connected between overlap joint 40 and the concrete.

Further, referring to fig. 7 and 8, in order to enhance the stability of the connection between the bridge 40 and the concrete, it is still further achievable that the diameter of the bridge 40 is gradually reduced from the end toward the second face to the end away from the second face. The part of overlap joint 40 and second face butt joint, the shape of overlap joint 40 is roughly the round platform structure of narrow down wide, and after concreting, the overlap joint 40 can be lived along lateral wall parcel to the concrete, based on the structure of overlap joint 40 to make the concrete can firmly live the cladding of overlap joint 40, be connected between overlap joint 40 and the concrete more stably. Simultaneously, because wide narrow down is presented in the shape of overlap joint 40, when using, overlap joint 40 passes through the butt of narrow end and adjacent floor deck plate body 200 to can effectively reduce the area of contact between overlap joint 40 and the floor deck plate body 200, when concreting, reduce the part that exposes of overlap joint 40. After the concrete solidifies, get rid of on the floor carrier plate of floor carrier plate body 200, only the narrow end of overlap joint 40 exposes outside, and can not rust to avoid the influence to floor bottom decorative effect.

In some embodiments of the present invention, referring to fig. 2 and 3, the number of the elastic claws 22 is at least two, and the at least two elastic claws 22 are arranged around the circumference of the support seat 21 at intervals. Taking elastic claws 22 as two examples, two elastic claws 22 are arranged on two opposite sides of the support seat 21, and under the action of external force, if being extruded by the mounting hole 11, the two elastic claws 22 can be close to each other, so that the space occupied by the two elastic claws 22 is reduced, and the elastic claws 22 can pass through the mounting hole 11. After the two elastic claws 22 pass through the mounting holes 11, the extrusion force exerted on the elastic claws 22 by the mounting holes 11 disappears, and the two elastic claws 22 rebound to the open state and are matched with the supporting seat 21, so that the supporting piece 20 is clamped on the connecting piece 10. It should be noted that the number of the elastic claws 22 may be set according to different requirements, and may be two, three or more, and in the embodiment of the present invention, the number of the elastic claws 22 is not specifically limited.

Referring to fig. 2, one way to realize the elastic claw 22 is that one end of the elastic claw 22 is connected to the supporting seat 21, and the other end extends in a direction away from the supporting seat 21 along the axial direction of the supporting seat 21. The side of the elastic claw 22 has a limiting protrusion 221, and the limiting protrusion 221 extends along the radial direction of the support seat 21 in a direction away from the central area of the support seat 21. For supporting seat 21, elasticity jack catch 22 has certain length, can be convenient for elasticity jack catch 22 to wear to establish in mounting hole 11, through spacing protruding 221 increase the thickness of elasticity jack catch 22 for elasticity jack catch 22 is difficult to break away from in the mounting hole 11, makes the block between elasticity jack catch 22 and the mounting hole 11 be connected more stably. Meanwhile, the displacement of the supporting member 20 relative to the connecting member 10 in the up-down direction can be further prevented by the engagement of the limiting protrusion 221 and the supporting seat 21.

Further, in order to make the supporting member 20 more easily pass through the mounting hole 11 to realize clamping, with reference to fig. 2, a side of the limiting protrusion 221 facing away from the central area of the supporting seat 21 is provided with a guiding inclined surface 222, and the thickness of the guiding inclined surface 222 gradually decreases from the second side to the first side. The structure of the limiting protrusion 221 is narrow at the top and wide at the bottom through the guiding slope 222, when the mounting hole 11 is penetrated, the elastic claw 22 firstly extends into the mounting hole 11 through the narrow end, and the mounting hole 11 gradually extrudes the elastic claw 22 along the guiding slope 222, so that the elastic claw 22 is more smoothly clamped into the mounting hole 11. After the elastic claw 22 passes through the mounting hole 11, the wide end of the limiting protrusion 221 is matched with the supporting seat 21, so that the support member 20 and the connecting member 10 are clamped.

In the embodiment of the invention, the mounting hole 11 can be in various shapes according to different requirements, and one implementation mode is that the mounting hole 11 is in a circular structure, so that the mounting hole 11 in the circular structure is easier to manufacture, and the manufacturing efficiency can be improved. Another way of realising the mounting hole 11 is that the mounting hole 11 is of a non-circular configuration. The mounting hole 11 is a polygonal structure which is clamped and connected with the elastic clamping jaw 22. If the mounting holes 11 are rectangular or other polygonal shapes, the elastic claws 22 can be correspondingly arranged according to the number of the elastic claws, and the mounting holes 11 with a non-circular structure can prevent the support member 20 from rotating when being connected with a fastener, thereby improving the connection efficiency and improving the connection strength.

Referring to fig. 2 and 3, in order to further enhance the connection strength between the supporting member 20 and the fastening member, in the embodiment of the invention, a connection nut 30 is disposed in the supporting seat 21, and a screw hole of the connection nut 30 is communicated with the connection hole 23. When joint formula coupling assembling 100 is connected on floor carrier plate body 200, support piece 20 accessible coupling nut 30 cooperation fastener is connected with floor carrier plate body 200 to can strengthen the joint strength between fastener coupling nut 30, avoid taking place the dropout condition, can improve joint strength and the reliability between joint formula coupling assembling 100 and the fastener, reduce the potential safety hazard. The coupling nut 30 may be disposed in the supporting seat 21 by injection molding, the supporting member 20 includes, but is not limited to, a plastic material and a rubber material, and is formed by injection molding, the elastic claw 22 and the supporting seat 21 are an integral structure, and the coupling nut 30 is injection molded in the supporting seat 21. The elastic clamping jaw 22 and the supporting seat 21 of the integrated structure can effectively avoid secondary connection between the elastic clamping jaw 22 and the supporting seat 21, and avoid the situation that the elastic clamping jaw 22 is separated from the supporting seat 21 or is broken.

In some embodiments of the present invention, the connecting member 10 is made of a metal material, and the steel bar truss 300 and the connecting member 10 are welded and fixed. The connecting member 10 includes, but is not limited to, a metal material such as stainless steel, galvanized sheet, galvanized alloy sheet, etc. The snap-in connection assembly 100 may be connected to the deck plate 200 by fasteners that pass through the deck plate 200 from one side of the deck plate 200, connect with the connection holes 23 on the support base 21, and connect with the connection nuts 30 in the connection holes 23, so as to fix the snap-in connection assembly 100 to the deck plate 200. The fastener includes but is not limited to a bolt or a screw, and the like, and the bolt or the screw includes but is not limited to a full thread and a half thread. The material for making the bolt or the screw rod includes but is not limited to iron material and stainless steel material. The bolt includes, but is not limited to, an inner hexagon bolt, an outer hexagon bolt, a cross bolt, a straight bolt, and the like. Further, for convenience of installation, through holes may be provided in a predetermined position of the floor support plate body 200 in advance, the through holes corresponding to the openings of the connection holes 23, and screws may be connected to the connection holes 23 through the through holes.

When the connection nut 30 is not disposed in the connection hole 23, in the embodiment of the present invention, the connection manner of the fastening member and the connection hole 23 includes multiple manners, and one manner that the connection hole 23 is a threaded hole matched with the fastening member, and the fastening member may be a screw, and a screw rod of the screw may be directly screwed into the connection hole 23 to achieve connection. Further, in order to improve the connection strength between the fastening member and the support base 21, the depth of the connection hole 23 is greater than the length of the screw screwed into the connection hole 23, and when the screw is connected with the support base 21, the screw rod of the screw penetrates through the floor support plate body 200 and then extends into the connection hole 23 to be connected with the connection hole 23. If the depth of the screw shaft of the screw extending into the connecting hole 23 is insufficient, the length of the screw for connection is insufficient, so that the connection strength is insufficient. Or, in order to facilitate the use of the screw, the head of the screw is usually thinner than the body of the screw, if the head of the screw is connected with the connecting hole 23, the connecting strength provided by the head of the screw is smaller, if the depth of the connecting hole 23 is greater than the length of the screw screwed into the connecting hole 23, namely, after the screw extends into the connecting hole 23, the screw of the screw completely extends into the connecting hole 23, and the part of the connecting hole 23, which exceeds the screw, provides a containing space for the head of the screw, so that the screw is connected with the connecting hole 23 through the body of the screw, thereby improving the connecting strength.

Another way of connecting the fastener to the connection hole 23 is that the radial dimension of the connection hole 23 is slightly smaller than the radial dimension of the fastener, and the fastener and the connection hole 23 can be connected by interference fit. For example, the fastening member may be a tapping screw, and when the tapping screw is screwed into the connection hole 23, the connection hole 23 is pressed, and the connection hole 23 wraps the tapping screw, thereby achieving connection.

In the embodiment of the present invention, the plane of the second surface of the connecting element 10 is higher than the plane of the floor deck plate 200 through the supporting element 20, and when the clip-type connecting assembly 100 is fixed on the floor deck plate 200, the connecting element 10 is not in contact with the connecting plate, so that concrete can more easily enter the bottom of the connecting element 10, that is, the connecting element 10 can be more easily wrapped, and the exposure of the connecting element 10 can be reduced. Meanwhile, the fastener can be wrapped by the supporting piece 20, so that the fastener for connection can be prevented from contacting with concrete and being wrapped by the concrete, the fastener is easier to detach, and the detachment efficiency is improved. After the concrete solidifies, get rid of on the floor carrier plate of floor carrier plate body 200, only support member 20's bottom exposes outside, support member 20 that plastic material or rubber materials made is convenient for be connected with sealing material, for example support member 20 is connected with sealing material, and simultaneously, support member 20 can not rust, can avoid the influence of rust to the bottom outward appearance of floor plate.
