Truss positioning support

Technical Field

The utility model belongs to the technical field of the construction equipment, concretely relates to truss location support.

Background

The truss refers to a truss girder and is a lattice-structured girder type structure; the truss structure is commonly used in public buildings such as large-span factory buildings, exhibition halls, gymnasiums, bridges and the like, wherein the simple truss structure consisting of a basic articulated triangle and sequentially added binary bodies is a commonly used truss structure type, in the field of building construction, a steel bar truss is more common, and is a truss formed by connecting steel bars serving as an upper chord, a lower chord and a web member through resistance spot welding,

the combined bearing plate formed by connecting the steel bar truss and the bottom plate into a whole through resistance spot welding is called a steel bar truss floor bearing plate, and has the advantages of realizing mechanical production, being beneficial to uniform arrangement intervals of steel bars and consistent thickness of a concrete protective layer, improving the construction quality of a floor slab, obviously reducing the quantity of steel bar binding engineering on site, accelerating the construction progress, increasing the construction safety guarantee and realizing civilized construction; the assembly type bottom plate and the connecting piece are convenient to disassemble and assemble, can be repeatedly used for many times, saves steel, and meets the national requirements of energy conservation and environmental protection.

However, the steel bar truss floor support plate has a serious defect that the steel bar truss floor support plate is easy to damage during transportation, because the truss structure is connected with the bottom plate only through electric welding, jolting easily in the transportation process to cause looseness of the connecting position and influence the stability of connection, and the steel bar truss floor support plate after connection cannot be reused, because the connection of welding points needs to be opened in repeated use, meanwhile, traces of the welding points need to be ground, the workload is large, in the actual production process, the recycling frequency of the bottom plate is only about 5 times, the recycling rate is low, and the use cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a truss positioning support not only can easy dismounting, and the recycling of being convenient for can reduce artifical intensity of labour moreover.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a truss positioning mount comprising: truss, sleeve pipe, seat body, place on the bottom plate seat body bottom surface, be provided with two tops protrudingly on the top surface of seat body, the interval between the top protrudingly is the same with two bottom chord intervals of truss, and two faces that the top is protruding relative are the arc, and the height that the top is protruding is not less than the diameter of truss reinforcing bar, and the supporting legs that seat body bottom surface and bottom plate are connected is located seat body bottom surface, and the side of seat body is connected with the sleeve pipe through connecting portion, and the sleeve pipe is hollow pipe, and its inner wall is provided with the screw thread, and the sleeve pipe is perpendicular with seat body bottom surface.

Furthermore, two weight reducing cavities are arranged in the two support legs on the bottom surface of the seat body, and each weight reducing cavity is a cuboid cavity.

Furthermore, the top surface of the seat body is detachably connected with a compression beam, the compression beam is a square tube, a plurality of through holes are formed in the compression beam, the positions of the through holes correspond to those of the sleeves, and the compression beam and the sleeves can be detachably connected to the bottom plate through bolts.

Further, the through hole of the compression beam is smaller than the size of the bolt and nut portion.

The utility model discloses following beneficial effect has at least:

(1) easy dismounting carries out the dismantlement through the screw that reserves on bolt and the bottom plate and is connected, and the installation effectiveness is higher, just can the direct use after demolising moreover, no longer need handle the bottom plate surface, and circulation efficiency improves.

(2) The bottom plate does not need bottom external support, so that the labor intensity of workers is reduced, the supporting cost is saved, and the construction period is shortened.

(3) The whole quality is lighter, is provided with on the seat and subtracts heavy chamber, has alleviateed the weight of self when not influencing the result of use, and the building carrier plate weight of assembling has also not add the location support and has increased by a wide margin.

(4) The recycling rate of the bottom plate is improved, the truss is fixed on the bottom plate through spot welding in the traditional bottom plate, so the truss needs to be separated before recycling, but the welding parts are tightly connected, the bottom plate can be damaged in the separation process, and the welding parts are roasted at high temperature in the welding process, so that the thermal stress is generated in the bottom plate, the performance of the bottom plate can be influenced without treatment, and the recycling service life is low.
