Wherein, the circumference periphery of joint post 20 is equipped with joint piece 21, and in the mounting hole 11 was worn to locate by joint post 20 part, joint piece 21 and first face butt. The clamping column 20 is provided with a connecting hole 22 along the axial direction through one end of the mounting hole 11. The positioning pad 30 is sleeved on the clamping column 20 and is abutted against the second surface.

The hooking stem 20 is connected to the fastening member through the connecting hole 22 so as to wrap the fastening member and prevent the fastening member from being exposed.

Referring to fig. 7 and 8, the connection assembly 100 may be used to connect the steel bar truss 300 to the floor deck plate 200, the connection assembly 100 may be connected to the floor deck plate 200 through a fastener, and the fastener may pass through the floor deck plate 200 and be connected to the locking post 20 in the locking assembly. The height of the connecting piece 10 can be increased through the positioning gasket 30 in the locking assembly, so that a gap is formed between the connecting piece 10 and the floor support plate body 200, the concrete can enter the bottom of the connecting piece 10 more easily, the connecting assembly 100 can be wrapped more easily by the concrete, and rusting caused by the fact that the connecting piece 10 is exposed is avoided. Simultaneously, live the fastener parcel through the lock solid subassembly, 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.

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 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 the effect of better plate bottom flatness.

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 includes, but is not limited to, plastic material, rubber material, and is formed by injection molding. 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 4, the clip column 20 can penetrate through 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, i.e., the connecting assembly 100.

Referring to fig. 7 and 8, the connecting assembly 100 can be connected to the floor plate 200 by fasteners (the fasteners are not shown), and the fasteners pass through the floor plate 200 from the side of the floor plate 200 and connect with the connecting holes 22 of the clamping posts 20, so as to fix the connecting assembly 100 to the floor plate 200. Fasteners include, but are not limited to, screws, self-tapping screws, and the like, including, but not limited to, full threads, half threads. 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 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, i.e., the connecting element 10 is more easily wrapped, and the exposure of the connecting element 10 is reduced. Simultaneously, can wrap up the fastener through the locking subassembly, can prevent like this that the fastener that is used for connecting from contacting with the concrete, prevent to be wrapped up by the concrete, it is easier when dismantling the fastener to improve and dismantle efficiency. After the concrete solidifies, get rid of on the floor bearing plate of floor bearing plate body 200, only the bottom of lock solid subassembly exposes outside, and the lock solid subassembly that plastic material or rubber materials made is convenient for be connected with sealed mud filling, and simultaneously, the lock solid subassembly can not rust, reducible to the influence of rust to floor plate outward appearance.

With continued reference to fig. 7 and 8, the steel bar truss 300 may be connected to the floor deck plate 200 through the connection assembly 100, 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, the steel bar trusses 300 with different specifications can be selected, and the specifications of the upper chord steel bars 301, the lower chord steel bars 302 and the web member steel bars 303 of the steel bar trusses 300 with different specifications can also be different, for example, the diameter range of the lower chord steel bars 302 can be selected according to different requirements, and the size range is different between 6 mm and 14 mm. The types of the upper chord reinforcements 301, the lower chord reinforcements 302 and the web member reinforcements 303 of the steel bar trusses 300 of different specifications may be different, and the types of the upper chord reinforcements 301, the lower chord reinforcements 302 and the web member reinforcements 303 of the same steel bar truss 300 may be different. For example, the rebar can be plain round rebar, ribbed rebar, and the like.

Be connected through coupling assembling 100 between steel bar truss 300 and the building carrier plate body 200, during the concreting, the concrete can wrap up coupling assembling 100, 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 plane, 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.

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. Referring to fig. 8, when the floor deck plate 200 is a profiled steel plate, the profiled steel plate has protruding ribs 201 and concave ribs arranged at intervals, and the connecting assembly 100 is connected to the protruding ribs 201. 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 convex ribs 201 and the mutual gomphosis overlap joint of a plurality of concave ribs of edge, and convex rib 201 and concave rib that the looks 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. The connecting piece is connected with profiled steel sheet, and the connecting piece adopts welding mode to be connected with steel bar truss, therefore profiled steel 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 steel sheet as the die block, there is not horizontal overlap joint in the die block, profiled steel sheet arranges for leading to long, and steel bar truss 300 adopts welding mode to be connected with coupling assembling 100, therefore profiled steel sheet can participate in the atress at the construction stage, compares other types of 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. 9 and 10 in conjunction with fig. 4, in order to enhance the stability of the connection between the locking assembly and the concrete, in the embodiment of the present invention, it is realized that the diameter of the positioning washer 30 is gradually reduced from the end facing the second surface to the end away from the second surface. The positioning gasket 30 is in a circular truncated cone structure with a wide top and a narrow bottom, after concrete is poured, the positioning gasket 30 can be wrapped by the concrete along the positioning side wall, and based on the structure of the positioning gasket 30, the positioning gasket 30 can be firmly wrapped by the concrete, and the locking assembly is more stably connected with the concrete. Simultaneously, because the shape of locating spacer 30 is wide from top to bottom narrow, when using, locating spacer 30 passes through narrow end and the butt of floor deck plate body 200 to can effectively reduce the area of contact between locating spacer 30 and the floor deck plate body 200, when concreting, reduce the exposure part of locating spacer 30. After the concrete is set, the floor deck plate 200 is removed, and only the narrow end of the positioning spacer 30 is exposed to the outside, thereby reducing the influence on the appearance of the floor deck plate.

Further, in order to enhance the connection stability between the locking assembly and the concrete, a connection protrusion is disposed on the outer wall of the positioning pad 30. The connecting projections extend in the radial direction of the positioning washer 30, and when concrete is poured, the connecting projections can be coated by the concrete, so that the connection stability between the locking assembly and the concrete is further improved. Alternatively, the outer wall of the positioning pad 30 is provided with a convex-concave structure. When concrete is poured, the concrete can penetrate into the convex-concave structure, so that the area of the positioning gasket 30 coated by the concrete is increased, and the connection stability between the locking assembly and the concrete is further improved.

In the embodiment of the present invention, referring to fig. 9, the positioning pad 30 and the fastening column 20 are connected by interference fit or by screw thread. The snap post 20 includes, but is not limited to, a cylindrical and polygonal structure, the positioning pad 30 is an annular structure, and the shape of the inner ring matches with the circumferential shape of the snap post 20. The radial dimension of the clamping column 20 can be slightly larger than that of the inner ring of the positioning gasket 30, and the positioning column can be extruded into the inner ring of the positioning gasket 30, so that interference fit connection is realized. Or, the outer wall of the clamping column 20 is provided with an external thread, and the inner ring of the positioning gasket 30 is provided with an internal thread used in a matching way, so that the positioning gasket 30 and the clamping column 20 can be in threaded connection. Of course, the interference fit connection and the screw connection can be used in combination, so that the connection between the positioning washer 30 and the clamping column 20 is more stable.

The joint piece 21 extends along the radial direction of joint post 20, has increased the radial dimension of joint post 20 through joint piece 21 to when joint post 20 penetrates mounting hole 11, can be spacing in first face, and cooperation positioning pad 30 is with the centre gripping of joint post 20 on connecting piece 10.

Another way to realize the clamping block 21 is that the clamping block 21 is a ring-shaped structure, and is circumferentially disposed on the clamping column 20 along the circumferential direction of the clamping column 20. Annular joint piece 21 has increased the radial dimension of joint post 20 to when joint post 20 penetrated mounting hole 11, can be spacing on first face, and cooperation locating washer 30 is with the centre gripping of joint post 20 on connecting piece 10.

In another way of realizing the clamping block 21, the clamping block 21 is a circular structure and is disposed on the end surface of the clamping column 20 far away from the first surface. By the arrangement mode, the clamping blocks 21 and the clamping columns 20 form a structure similar to a nail, and the clamping columns 20 are clamped on the connecting piece 10 through the clamping blocks 21 matched with the positioning gaskets 30.

Further, referring to fig. 1 and 2, an avoiding inclined surface 23 is disposed at an end of the clamping block 21 away from the clamping column 20. By avoiding the inclined surface 23, the concrete can be easily coated on the clamping column 20 and the clamping block 21, so that the connection between the clamping column 20 and the concrete is more stable.

Referring to fig. 11 and 12 in combination with fig. 1, 5 and 6, in the embodiment of the present invention, for convenience of various different installation manners, a plurality of installation holes 11 are provided, and the installation holes 11 are arranged at intervals along the length direction of the connecting member 10. At least a part of the mounting holes 11 are provided with locking components.
