According to the technical scheme provided by the embodiment of the invention, referring to fig. 7, the lap joint type connecting assembly 100 can be used for connecting the steel bar truss 300 to the floor slab 200, the lap joint type connecting assembly 100 can be connected with the floor slab 200 through a fastener, the height of the connecting piece 10 can be increased through the locking assembly, so that concrete can easily enter the bottom of the connecting piece 10, the lap joint type connecting assembly 100 can be easily wrapped by the concrete, and rusting caused by exposure of the connecting piece 10 is avoided. Simultaneously, live the fastener parcel through the lock solid subassembly, prevent that concrete from wrapping up the fastener, reduce the dismantlement degree of difficulty of fastener, improve and dismantle efficiency. Meanwhile, 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 lap joint type connecting 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.

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

In the embodiment of the present invention, the connecting member 10 includes, but is not limited to, a metal material, such as stainless steel, galvanized sheet, galvanized alloy sheet, and the like. The locking assembly is made of plastic materials and rubber materials, and is formed through an injection molding process, so that the locking assembly cannot rust, and the decorative effect of the plate bottom cannot be influenced. The support member 40 includes, but is not limited to, a plastic material, a rubber material, and is formed by an injection molding process to prevent rust.

In order to strengthen the connection stability between the clamping block 21 and the clamping column 20, the clamping block 21 and the clamping column 20 are of an integrally formed structure, so that the secondary connection between the clamping block 21 and the clamping column 20 is avoided, and the occurrence of the broken condition is reduced. Referring to fig. 1 and 2, the clip column 20 can be inserted into the mounting hole 11, one end of the clip column 20 penetrates through the second surface, the clip block 21 is limited on the first surface, and the positioning pad 30 is sleeved on the portion of the clip column 20 penetrating through the second surface and abutted against the second surface, so that the locking assembly and the connecting member 10 form a whole.

Referring to fig. 7, the lap joint assembly 100 may be connected to the floor deck plate 200 by fasteners (the fasteners are not shown), the fasteners pass through the floor deck plate 200 from the side of the floor deck plate 200 and connect with the connection holes 22 of the fastening posts 20, so as to fix the lap joint assembly 100 to the floor deck plate 200, and the end of the connecting member 10 provided with the supporting member 40 extends out of the floor deck plate 200. The connector 10 may extend at least one end of the deck plate 200, i.e., the connector 10 may have a support member 40 at least one end.

Fasteners, including but not limited to screws, self-tapping screws, etc., for attaching the connector 10 to the floor deck plate 200 include but are not limited to full threads, half threads, etc. The screw and the self-tapping screw are made of materials including, but not limited to, iron materials and stainless steel materials. The screw includes, but is not limited to, a hexagon socket screw, a cross screw, a straight screw, etc. Further, for the 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 22, and screws may be connected to the connection holes 22 through the through holes.

In the embodiment of the present invention, the connection manner between the fastening member and the connection hole 22 includes various manners, and one way to achieve this is that the connection hole 22 is a threaded hole matched with the fastening member, the fastening member may be a screw, and a screw rod of the screw may be directly screwed into the connection hole 22 to achieve connection. Further, in order to improve the connection strength between the fastening piece and the clamping column 20, the depth of the connection hole 22 is greater than the length of the screw screwed into the connection hole 22, and when the fastening piece is connected with the clamping column 20 through the screw, the screw rod of the screw penetrates through the floor bearing plate body 200 and then extends into the connection hole 22 to be connected with the connection hole 22. If the depth of the screw rod extending into the connection hole 22 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 22, the connecting strength provided by the head of the screw is smaller, if the depth of the connecting hole 22 is greater than the length of the screw screwed into the connecting hole 22, namely, after the screw extends into the connecting hole 22, the screw of the screw completely extends into the connecting hole 22, and the part of the connecting hole 22, which exceeds the screw, provides a containing space for the head of the screw, so that the screw is connected with the connecting hole 22 through the body of the screw, thereby improving the connecting strength.

Another way of connecting the fastener to the connection hole 22 is that the radial dimension of the connection hole 22 is slightly smaller than the radial dimension of the fastener, and the fastener and the connection hole 22 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 22, the tapping screw presses the connection hole 22, and the connection hole 22 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 by the locking assembly, and when the lap-joint type connecting element 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. Simultaneously, can wrap up the fastener through the lock solid subassembly, can prevent like this that the fastener that is used for connecting is wrapped up by the concrete, and it is easier when dismantling the fastener to improve and dismantle efficiency. After the concrete is solidified, the floor deck plate body 200 is removed, only the bottom of the locking assembly is exposed outside, and the locking assembly made of plastic materials or rubber materials is convenient to be connected with sealing filling mud.

With continued reference to fig. 7, the steel bar truss 300 may be connected to the floor deck plate 200 by the lap joint assembly 100, and in an embodiment of the present invention, the steel bar truss 300 is implemented in a manner that the steel bar truss 300 includes an upper-chord steel bar 301, two lower-chord steel bars 302 located at two sides below the upper-chord steel bar 301, and web members 303 having two ends respectively fixedly connected to the upper-chord steel bar 301 and the lower-chord steel bars 302. The steel bar truss 300 is respectively connected and fixed with the connecting piece 10 through the two lower chord steel bars 302, the lower chord steel bars 302 are connected with the connecting piece 10 in a welding mode, sliding cannot occur between the steel bar truss 300 and the connecting piece 10, the steel bar truss 300 and the floor bearing plate body 200 form a whole, the situation that relative sliding easily occurs between the steel bar truss 300 and the floor bearing plate body 200 in a construction stage is reduced, the rigidity of the floor bearing plate in a floor construction stage is increased, the deformation of a bottom template is reduced, and the flatness of the bottom of the floor is better guaranteed.

Further, according to different requirements, steel bar trusses with different specifications can be selected, the specifications of the upper chord steel bar 301, the lower chord steel bar 302 and the web member steel bar 303 of the steel bar truss 300 with different specifications can also be different, for example, the diameter range of the lower chord steel bar 302 can be selected according to different requirements, and the size range is different between 6 mm and 14 mm. The steel bar truss 300 of different specifications may have different types of the upper chord steel bar 301, the lower chord steel bar 302 and the web member steel bar 303, and the same steel bar truss 300 may have different types of the upper chord steel bar 301, the lower chord steel bar 302 and the web member steel bar 303. For example, the rebar can be plain round rebar, ribbed rebar, and the like.

Connect through overlap joint formula coupling assembling 100 between steel bar truss 300 and the building carrier plate body 200, during the concreting, overlap joint formula coupling assembling 100 can be wrapped up to the concrete, the bottom place plane of connecting piece 10 is higher than building carrier plate body 200 place plane, the bottom place plane of connecting piece 10 has the clearance between the plane of building carrier plate body 200 place promptly, can make the concrete get into the bottom of connecting piece 10 more easily, make the concrete wrap up connecting piece 10 more easily, solidify into the building carrier plate when the concrete, when dismantling building carrier plate body 200 from the building carrier plate, in order to reduce the exposure of connecting piece 10 on the building carrier plate. Meanwhile, the part extending out of the floor bearing plate body 200 through the connecting piece 10 is matched with the supporting piece 40, and can be lapped on the adjacent floor bearing plate body 200, the adjacent floor bearing plate body 200 plays a supporting role, and the number of splicing seams between the two adjacent floor bearing plate bodies 200 is reduced when concrete is poured.

In the embodiment of the present invention, the floor deck plate 200 includes, but is not limited to, one of a galvanized plate, a galvanized alloy plate, a figured steel plate, a bamboo plywood plate, a wood formwork, a wood-plastic plate, an injection molding plate, an aluminum alloy formwork, and a profiled steel plate. When the floor deck plate body 200 is a profiled steel sheet, the profiled steel sheet is provided with convex ribs and concave ribs which are arranged at intervals, and the lap joint type connecting assembly 100 is connected on the convex ribs. After the concrete is solidified on the profiled steel sheet, the floor support plate of the floor support plate body 200 is removed, the position of the connecting piece 10 is an upward concave structure, and the concave structure can be filled with sealing filling mud, so that the bottom of the locking assembly is covered by the sealing filling mud, and the locking assembly is prevented from being exposed.

For example, when the floor deck panel 200 is a profiled steel sheet, it is not limited to be formed by pressing a sheet such as galvanized sheet or cold-rolled sheet. Two adjacent profiled sheet accessible are located a plurality of fin and the mutual gomphosis overlap joint of a plurality of concave ribs of edge, and the fin and the concave rib that mutually gomphosis is in the same place can make two profiled sheet overlap joints reliable, and can effectively avoid leaking the thick liquid. The plurality of floor deck plates 200 are overlapped to form an integral structure, thereby improving continuous supporting force. Connecting piece 10 is connected with profiled sheet, and the connecting piece adopts the welding mode to be connected with steel bar truss, therefore profiled sheet can participate in the atress at the construction stage, reduces the deformation of building carrier plate at the construction stage, improves the roughness effect of building carrier plate bottom. The part of the floor deck, which is sunken upwards, can be filled with elastic bonding mortar or wall mud materials or plugging materials with similar performance.

In order to further improve the rigidity of the profiled steel sheet, the profiled steel sheet is also provided with transverse ribbing so as to enhance the rigidity of the profiled steel sheet, reduce the deformation and improve the flatness effect of the floor support plate.

When adopting floor bearing plate body 200 to be profiled sheet, profiled sheet is as removable die block, and disposable can satisfy relevant technical specification requirement, still has the residual value about raw and other materials cost 40% after the profiled sheet is demolishd, for the removable die block of bamboo offset plate or the removable die block of aluminum alloy, profiled sheet has market competition economically. And the profiled steel sheet does not need to return to a factory to do a large amount of work such as cleaning, detection and secondary processing, so that the investment of production personnel is greatly reduced, the production procedures are reduced, the production efficiency is accelerated, and the production cost is reduced. Simultaneously, adopt profiled sheet as the die block, there is not the horizontal overlap joint in the die block, profiled sheet arranges for leading to long, and steel bar truss 300 adopts welding mode to be connected with overlap joint formula coupling assembling 100, therefore profiled sheet can participate in the atress at the construction stage, compares other types removable truss plates and has better rigidity at the construction stage, has stronger ability of resisting construction load deformation, can improve the roughness effect of floor support plate bottom greatly.

Referring to fig. 1 and 2, in the embodiment of the present invention, at least one end of the connecting member 10 is provided with a supporting hole, which is not shown in the drawings, if one end of the connecting member 10 extends out of the floor deck plate 200, one end of the connecting member 10 is provided with a supporting hole, and if both ends of the connecting member 10 extend out of the floor deck plate 200, both ends of the connecting member 10 are provided with supporting holes, so as to connect the supporting member 40 through the supporting holes.

Referring to fig. 8 to 10, one implementation manner of the supporting member 40 is that the supporting member 40 includes a supporting column 41 and a fixing washer 42, a limiting head 43 is disposed at one end of the supporting column 41, the supporting column 41 is at least partially inserted into the supporting hole, and the limiting head 43 abuts against the first surface or the second surface. The fixing pad 42 is sleeved on the supporting column 41 and is correspondingly abutted against the second surface or the first surface. The radial dimension of the support post 41 may be slightly larger than the radial dimension of the support hole so that an interference fit connection between the support post 41 and the support hole is possible. When using, spacing head 43 can use up, and spacing head 43 and first face butt promptly, fixed shim 42 is located second face one side correspondingly, cup joints with the second face butt on support column 41 back. Or, the limiting head 43 can be used downward, that is, the limiting head 43 abuts against the second surface, and accordingly the fixing gasket 42 is located on one side of the first surface and abuts against the first surface after being sleeved on the supporting column 41, as shown in fig. 2, that is, the limiting head 43 can be used downward.

Further, in order to enhance the stability of the connection between the supporting member 40 and the concrete, it is possible to provide the outer wall of the spacing head 43 and/or the fixing washer 42 with a convex structure and/or a concave structure. The protruding structures extend along the radial direction, and when concrete is poured, the concrete can cover the protruding structures and the recessed structures, so that the connection stability between the support piece 40 and the concrete is further improved.

Further, in order to enhance the stability of the connection between the supporting member 40 and the concrete, it is also achievable that the diameter of the fixing washer 42 or the spacing head 43 is gradually reduced from the end toward the connecting member 10 to the end away from the connecting member 10. When fixing gasket 42 or spacing head 43 and second face butt, fixing gasket 42 or spacing head 43's shape is roughly wide round platform structure down, and behind the concreting, the concrete can wrap fixing gasket 42 or spacing head 43 along the lateral wall, based on fixing gasket 42 or spacing head 43's structure to make the concrete can firmly wrap fixing gasket 42 or spacing head 43, support piece 40 and be connected between the concrete more stable. Meanwhile, because the shape of the fixed gasket 42 or the limiting head 43 is wide at the top and narrow at the bottom, when the fixing device is used, the fixed gasket 42 or the limiting head 43 is abutted against the adjacent floor bearing plate body 200 through the narrow end, so that the contact area between the fixed gasket 42 or the limiting head 43 and the floor bearing plate body 200 can be effectively reduced, and the exposed part of the fixed gasket 42 or the limiting head 43 is reduced when concrete is poured. After the concrete solidifies, get rid of on the floor carrier plate of floor carrier plate body 200, only the narrow end of fixation gasket 42 or spacing head 43 exposes outside, can not rust to the reduction is to floor bottom decorative effect's influence.

In the embodiment of the present invention, the fixing pad 42 is connected with the supporting column 41 by interference fit or by screw thread. The support post 41 includes, but is not limited to, a cylindrical, polygonal structure, and the fixing washer 42 is an annular structure, and the shape of the inner ring matches the circumferential shape of the support post 41.

For example, the positions of the plurality of overlapping connection assemblies 100 in two connector buckle groups spaced by one row are arranged in a one-to-one correspondence, and the positions of the plurality of overlapping connection assemblies 100 in two adjacent rows of connector buckle groups are arranged in a staggered manner. For another example, the staggered arrangement of a portion of the overlapping connection assemblies 100 in two adjacent rows of fastener groups, and the opposite arrangement of a portion of the overlapping connection assemblies 100. It should be noted that, in the embodiment of the present invention, the number of the steel bar trusses 300 includes, but is not limited to, two, three, and other numbers, and the number of the steel bar trusses 300 arranged on the floor deck plate 200 may be set according to different needs, which is not specifically limited in the embodiment of the present invention.

With continued reference to fig. 16 to 17, in the embodiment of the present invention, according to different overlapping requirements, one end of the connecting element 10 may extend out of the floor deck plate 200, or both ends of the connecting element may extend out of the floor deck plate 200, so as to overlap the first surface of the adjacent floor deck plate 200, and reduce splice joint dislocation when concrete is poured.

Further, in the embodiment of the present invention, in order to meet different overlapping requirements, the arrangement of the connecting members 10 includes various ways, and one way to realize that the connecting members 10 extend out of the same side of the floor deck plate 200. A plurality of connecting pieces 10 can overlap joint simultaneously on same one side adjacent building carrier plate body 200, but adjacent building carrier plate body 200 overlap joint is on another adjacent building carrier plate body 200, a plurality of building carrier plate body 200 overlap joint each other like this to form a whole, when concreting, the impact force and the gravity of concrete are shared jointly to a plurality of mutually overlapping building carrier plate body 200, thereby can effectively reduce the condition appearance of overlap joint dislocation. The same one side that a plurality of connecting pieces 10 stretched out the building carrier plate body 200 can conveniently be under construction, and the specification of every building carrier plate body 200, the mounted position of each connecting piece 10 is all unified to be set for, makes things convenient for the construction operation, also makes things convenient for the mill to quantify the building carrier plate body 200 that has connecting piece 10 simultaneously.

Alternatively, a portion of the connector 10 may extend beyond one side of the deck plate 200 and another portion of the connector 10 may extend beyond the other side of the deck plate 200. On the adjacent floor carrier plate body 200 of a plurality of connecting pieces 10 overlap joint both sides simultaneously, adjacent floor carrier plate body 200 also can overlap joint on the adjacent floor carrier plate body 200 of its both sides, a plurality of floor carrier plate bodies 200 overlap joint each other like this to form a whole, when concreting, the impact force and the gravity of concrete are shared jointly to a plurality of mutually overlapping floor carrier plate bodies 200, thereby can effectively reduce the condition appearance of overlap joint dislocation. Meanwhile, construction can be facilitated, the specification of each floor support plate body 200 and the installation position of each connecting piece 10 are uniformly set, construction operation is facilitated, and meanwhile, the floor support plate body 200 with the connecting pieces 10 is conveniently manufactured in a factory in a quantized mode.

When the connecting members 10 respectively extend out of both sides of the floor deck plate 200, referring to fig. 16, the positions of the connecting members 10 respectively extending out of the opposite sides of the floor deck plate 200 are corresponding to or staggered with each other. Taking the orientation of fig. 16 as an example, a portion of the connectors 10 on the deck plate 200 extend above and a portion of the connectors 10 extend below the deck plate 200. The relative positions of the connecting pieces 10 extending out of the two sides can be correspondingly arranged or staggered. When two floor support plates 200 are being spliced, the connectors 10 extending out of the upper side can be lapped on the first face of the floor support plate 200 located above the connectors by extending out of the upper part to fit the support members 40, and the connectors 10 extending out of the lower side can be lapped on the first face of the floor support plate 200 located below the connectors by extending out of the lower part to fit the support members 40, so that the floor support plates 200 on both sides provide support for the connectors.

Further, referring to fig. 17, still another arrangement of the connector 10 is that two ends of the connector 10 extend out of the opposite sides of the floor deck plate 200. When two floor deck boards 200 are being spliced, the connecting member 10 may be overlapped on the first faces of the floor deck boards 200 positioned at the left and right sides thereof by portions extending from both ends, so that the floor deck boards 200 at both sides provide support thereto.

It should be noted that, with reference to fig. 16 and 17, the implementation manner and the extending manner of the connecting element 10 described above can be implemented and applied separately or combined with each other, and the connecting element 10 extending out of the floor support plate body 200 and the connecting element 10 not extending out of the floor support plate body 200 can also be combined and applied, which is not limited in the embodiment of the present invention.

For example, the connecting member 10 may be arranged in any of the following manners, but is not limited thereto.

Referring to fig. 7, 14 and 15, among the plurality of connecting members 10, one end of a portion of the connecting members 10 extends out of the same side of the floor deck plate 200. A portion of the connector 10 may not extend beyond the floor deck plate 200.

The connector 10 may be connected to one steel bar truss 300 or to a plurality of steel bar trusses 300.

Referring to fig. 16, in the plurality of connecting members 10, a portion of the supporting member 40 extends out of one side of the deck plate 200, and another portion of the supporting member 40 extends out of the other side of the deck plate 200. A portion of the connector 10 may not extend beyond the floor deck plate 200. The positions of the connectors 10 extending from the floor deck plates 200 may be staggered or opposite to each other.

Referring to fig. 17, both ends of the connecting member 10 extend out of the floor deck plate 200, and a portion of the connecting member 10 may not extend out of the floor deck plate 200. The connecting members 10 with two ends extending out of the floor deck plate 200 and the connecting members 10 with one ends extending out of the floor deck plate 200 can be combined for use.
