The utility model provides a detachable steel bar truss building carrier plate of die block includes the truss reinforcing bar and connects at the platelike die block 8 of truss reinforcing bar bottom, convenient and easy to detach simultaneously with die block 8 and the reliable connection of truss reinforcing bar, and die block 8 sets up the hole of wearing to establish that runs through its thickness direction. For example, iron wires can be used to penetrate through the through holes to bind and fix the bottom die 8 to the truss steel bars; the bolt can be connected with the truss steel bar through the through hole, and one end of the truss steel bar is welded with the nut matched with the bolt. The utility model discloses a detachable design of die block for after accomplishing the pouring of concrete, can demolish die block 8, realize the reuse of die block 8, and then reduce construction cost; meanwhile, the bottom die 8 is prevented from influencing the decoration of the building surface layer in the later period.
The following description is made in detail with reference to the accompanying drawings and specific embodiments for the detachable steel bar truss floor support plate with the bottom die provided by the present invention.
The utility model provides an in a concrete embodiment, die block 8 and truss reinforcing bar pass through the bolt and wear to establish the hole, and with the nut cooperation of setting on the truss reinforcing bar, realize dismantling of die block 8 and be connected, both guaranteed the convenience that die block 8 dismantled, guaranteed the joint strength of die block 8 with the truss reinforcing bar simultaneously, avoided the risk that die block 8 drops appearing when carrying out concrete placement.
Furthermore, a concrete cushion block 4 is arranged between the truss steel bars and the bottom die 8, and the concrete cushion block 4 has the function of isolating the bottom die 8 from the truss steel bars to a certain extent, so that the bottom die 8 is prevented from being difficult to detach after the concrete is solidified; the reason for adopting concrete cushion 4 lies in making concrete cushion 4, truss reinforcing bar and the concrete integrated into one piece of pouring, promoting the intensity of building surface course. The concrete cushion block 4 is generally a cushion block with high strength and light weight, and a thin steel wire or a steel bar is generally poured in the cushion block 4 to improve the strength and the crack resistance of the concrete cushion block 4.
Specifically, the truss steel bars comprise a plurality of lower chord steel bars 1 which are arranged in the same plane and are parallel to each other, in this embodiment, two steel bars are taken as an example, and the truss steel bars further comprise upper chord steel bars 2 which are arranged above the lower chord steel bars 1 and are parallel to the lower chord steel bars 1, wherein the upper chord steel bars 2 are specifically one steel bar, and one upper chord steel bar 2 is arranged right above the middle of the two upper chord steel bars 2; the upper chord steel bar 2 and the lower chord steel bar 1 are fixedly connected through the connecting steel bar 3 which is obliquely arranged to form a triangular prism shape.
The upper end face, used for laminating the truss reinforcing steel bar, of the concrete cushion block 4 is provided with a semi-cylindrical limiting groove 42 for limiting the lower chord reinforcing steel bar 1, and the concrete cushion block 4 is tightly laminated with the truss reinforcing steel bar through the matching of the limiting groove 42 and the lower chord reinforcing steel bar 1. In addition, a first through hole 41 is formed in the center of the concrete cushion block 4; the pressing nut 5 used for pressing the lower chord steel bar 1 in the limiting groove 42 of the concrete cushion block 4 is arranged above the lower chord steel bar 1, the pressing limiting portion is arranged on the side portion of the pressing nut 5, pressing of the lower chord steel bar 1 is achieved through the pressing limiting portion, and detachable connection of the truss steel bar and the bottom die 8 is achieved through connection of the tensioning bolt 6 and the pressing nut 5.
In the above embodiment, the pressing nut 5 is in a long cylindrical shape, the pressing limiting portion is a dowel 52 vertically penetrating through the upper section of the pressing nut 5, the upper section of the pressing nut 5 is provided with a jack for the dowel 52 to penetrate through, and the lower section of the pressing nut 5 is used for being matched and screwed with the tensioning bolt 6. When the tensioning bolt 6 is screwed by a wrench, the dowel 52 presses the lower chord steel bar 1 until the bottom die 8 and the truss steel bar are tightly connected, the lower chord steel bar 1 is accommodated in the limiting groove 42, and the concrete cushion block 4 is tightly attached to the truss steel bar and the bottom die 8.
In order to prevent the insertion rib 52 from slipping off, the insertion rib 52 is fixed to the compression nut 5 by welding after passing through the insertion hole. The dowel 52 specifically refers to a reinforcing steel bar penetrating through the insertion hole, and the design that the dowel 52 penetrates through the press nut 5 is to avoid that the press limiting part is easily separated from the side wall of the press nut 5 due to the direct welding of the press limiting part, so that the bottom die 8 is not firmly connected with the truss reinforcing steel bar.
The arrangement of the truss reinforcing steel bars is that the strength of the poured concrete is improved, and meanwhile, the truss reinforcing steel bars are connected with the supporting bottom die 8, and the structure of the truss reinforcing steel bars can be flexibly arranged according to actual needs. The number of the limiting grooves 42 on the upper end surface of the concrete cushion block 4 and the distance between the adjacent limiting grooves 42 are matched with the lower chord steel bars 1 of the truss steel bars all the time no matter the number of the lower chord steel bars 1.
The press-fit nut 5 can be specifically composed of a nut with an inner diameter of 8mm and HRB 400-grade steel bars with a diameter of 8mm, the tensioning bolt 6 is correspondingly composed of a bolt with a diameter of 8mm, no matter which specification of the press-fit nut 5 or the tensioning bolt 6 is adopted, the connection strength of the bottom die 8 and the truss steel bars is guaranteed on the premise, the bottom die 8 is convenient to disassemble, and the length of the dowel bar 52 meets the requirement of press-fit of all the lower chord steel bars 1.
In a further embodiment, a gasket 7 is further arranged between the bottom die 8 and the tensioning nut, the tensioning bolt 6 can be conveniently screwed to detach the bottom die 8 through the gasket 7, and the problem that the bottom die 8 and the bolt are solidified and are difficult to screw in the concrete pouring process is avoided. For protection of the tensioning screw 6, the diameter of the washer 7 is larger than the diameter of the tensioning screw 6, typically more than twice the diameter of the tensioning screw 6. For example, when the tightening bolt 6 is a bolt having a diameter of 8mm, the washer 7 has an inner diameter of 9mm, an outer diameter of usually about 30mm, and a thickness of about 1 mm.
In the work progress, assemble the detachable steel bar truss floor carrier plate of the above-mentioned specification of polylith, pass through the die block 8 and realize being connected with the truss reinforcing bar through cushion, tensioning bolt 6 and compression nut 5, it can to have pour the concrete and twist after waiting the concrete solidification and move tensioning bolt 6 and demolish tensioning bolt 6, gasket 7 and die block 8 in proper order, makes things convenient for die block 8 to carry out reuse. The bottom mold 8 may be a mold plate made of bamboo plywood or the like.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
It is right above the utility model provides a detachable steel bar truss building carrier plate of die block has carried out detailed introduction. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
