[0002] Patent CN217734513U discloses an assembled steel truss floor deck, which relates to the field of building structures, including a base plate and a steel truss, wherein a steel mesh is embedded in the base plate, the steel mesh is provided with a slot, the steel trusses are arranged in parallel and at intervals, and the steel trusses are embedded in the slots so that the steel trusses are clamped with the steel mesh; the clamping method makes the steel trusses more convenient during installation, and effectively reduces the construction error caused by position offset; the base plate is cast with concrete, and bears external loads together with the cast-in-place concrete floor slab, thus becoming a part of the floor slab in the building, avoiding the need to remove the formwork, and the problem of holes and gaps in the floor slab after the formwork is removed after the concrete is poured and formed. However, the patent still has the following problems in actual use:

[0003] Although the steel mesh and the lower chord steel bars in the above-mentioned device can be spliced ​​together with auxiliary welding, the position of the steel mesh slot is fixed, resulting in that the base plate can only be applied to a steel truss of a fixed specification. In addition, due to the errors in the production of the steel truss itself, the spacing between the two lower chord steel bars is not completely fixed to the specified parameters. However, the length of the steel mesh slot is fixed, so the device cannot stably clamp the steel truss. In addition, the base plate in the above-mentioned device is directly cast with concrete, which is not convenient for transporting to high floors during on-site construction. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figures 1 to 6 , the utility model provides a technical solution:

[0026] A steel truss floor deck that is easy to assemble, comprising a steel truss plate 1, a mounting mechanism 3 is arranged below the lower chord steel bars 101 of the steel truss plate 1, the mounting mechanism 3 comprises a bottom template 301, and a clamping assembly 2 is arranged between the bottom template 301 and the lower chord steel bars 101;

[0027] Among them, the positioning component 2 includes a lifting rail 201 fixed symmetrically to the top surface of the bottom template 301, and a rail groove 203 is opened inside the lifting rail 201. The rail groove 203 is slidably connected with a plurality of positioning blocks 202, and the top of the positioning block 202 is engaged with the lower chord steel bar 101; two connected positioning blocks 202 form a group, and the two positioning blocks 202 of the same group are fixedly connected to the side plate 204 on the side away from each other, and the side plate 204 is rotatably connected to the rotating shaft 205 in the vertical direction, and the top of the rotating shaft 205 is fixedly connected to a knob, and the bottom of the rotating shaft 205 is fixedly connected to a sliding column 208, and the sliding column 208 is slidably connected to the lifting rail 201; the spacing between the two positioning blocks 202 can adapt to the clamping of two lower chord steel bars 101 with different spacings, and the position of the positioning block 202 can be quickly fixed, so that the position of the entire steel truss plate 1 will not change due to subsequent construction.

[0028] An elliptical rubber plate 209 is fixedly connected to the outer side of the sliding column 208. The longest diameter of the elliptical rubber plate 209 is greater than the width of the rail groove 203, and the shortest diameter of the elliptical rubber plate 209 is less than the width of the rail groove 203. The friction between the longest part of the elliptical rubber plate 209 and the inner wall of the lifting rail 201 will hinder the movement of the positioning block 202.

[0029] A limiting column 206 is fixedly connected to the middle part of the rotating shaft 205, and a limiting groove 207 is provided inside the side plate 204. The limiting groove 207 is an arc groove with an arc slightly greater than 90 degrees, and the limiting column 206 is slidably connected to the limiting groove 207; the limiting column 206 is located at both ends of the limiting groove 207, which respectively correspond to the two states of the elliptical rubber plate 209 being in contact with and detached from the lifting rail 201.

[0030] The bottom formwork 301 is made of metal aluminum, and a casting cavity 302 is opened inside the bottom formwork 301. The length of the bottom formwork 301 is longer than the lower chord steel bar 101. The bottom formwork 301 is an aluminum product, and compared with direct cement casting, it is lighter, which makes it easier for the bottom formwork 301 to be transported to different floors.

[0031] A plurality of through holes 303 are provided in the middle of the bottom formwork 301, and the through holes 303 connect the upper and lower sides of the bottom formwork 301; pouring ports 304 are provided on the tops of both sides of the bottom formwork 301; the pouring ports 304 pour cement into the pouring cavity 302, and the cement passes through the through holes 303 to form a whole with the bottom formwork 301, the building body, and the steel truss plate 1.

[0032] The working principle of the above-mentioned steel truss floor deck which is easy to assemble is as follows:

[0033] Before using this easy-to-assemble steel truss floor deck, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, firstly, the distance between the two lifting rails 201 of the same group is adjusted, so that the lower chord steel bar 101 is clamped into the clamping block 202, and then the clamping block 202 is pushed to slide in the rail groove 203, so that the two clamping blocks 202 can stably adapt to clamp the two lower chord steel bars 101 with different spacings from both sides, and then the rotating shaft 205 is rotated to make the limiting column 206 slide from one end of the limiting groove 207 to the other end, and the lifting rail 201 is pressed and deformed by the elliptical rubber plate 209, so that the distance between the two clamping blocks 202 can finally adapt to clamp the two lower chord steel bars 101 with different spacings, and the position of the clamping block 202 can be quickly fixed, so that the position of the entire steel bar truss plate 1 will not be changed due to subsequent construction;

[0034] The friction between the elliptical rubber plate 209 and the inner wall of the lifting rail 201 will hinder the movement of the positioning block 202;

[0035] After installing the steel truss plate 1, cement is first poured into the pouring cavity 302 through the pouring port 304. The cement passes through the through hole 303 to form the bottom formwork 301, the building body, and the steel truss plate 1 into one body to avoid disassembly. In addition, the bottom formwork 301 is made of aluminum and is light in weight, which makes it convenient to transport the bottom formwork 301 to different floors.

[0036] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
