Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figures 1 to 5, the utility model provides a kind of detachable bed die formula steel bar truss floor support plate, they many steel bar girders 20 comprising bed die 30 and be disposed in parallel on bed die 30; Steel bar girder 20 comprises the reinforcing bar 21 that winds up, be positioned at the web member reinforcing bar 23 that two lower edge reinforcing bars 22 of both sides below the reinforcing bar 21 that winds up and two ends are fixedly connected with lower edge reinforcing bar 22 with the reinforcing bar 21 that winds up respectively; Every bar steel bar girder 20 is connected with bed die 30 respectively by the multiple junction buttons 10 being positioned at a row; Junction button 10 top offers rectangular channel 11, and two relative side correspondences of rectangular channel 11 offer draw-in groove 12, and two lower edge reinforcing bars 22 of steel bar girder 20 are fastened in two draw-in grooves 12 of junction button 10 respectively, and junction button 10 is fixedly connected with bed die 30 by securing member.Particularly, screw 40 can be selected to removably connect to make junction button 10 and bed die 30 be formed as securing member.The contour structures of junction button 10 can have multiple, as long as have the draw-in groove 12 that can block and establish two lower edge reinforcing bars 22, in order to can mass production, at a preferred embodiment, junction button 10 is by the orthogonal block body of plastic material integrated die-casting, and rectangular channel 11 is formed in the upper surface of rectangular block body.Bed die 30 can adopt bamboo slab rubber or the wood glue plate that density is less, thickness that is that be easy to process is generally 15mm-25mm, and the larger thickness of Rigidity and strength also can be adopted to be generally the galvanized sheet of 1mm-2mm or zinc-plated checkered steel plate.
As shown in Figure 3 and Figure 5, due to every bar steel bar girder 20 with only arrange junction button 10 by one between bed die 30 and be connected, each junction button 10 correspondence is provided with two draw-in grooves 12, two lower edge reinforcing bars 22 are fastened in two draw-in grooves 12 of same junction button 10, under concrete gravity effect, although two lower edge reinforcing bars 22 have counter motion trend, and it is identical to form size, two outside thrusts that direction is contrary, but for each junction button 10, the size simultaneously acted on it is identical, contrary two thrusts in direction are cancelled out each other, in fact, this junction button 10 has self-balancing effect, this junction button 10 balances two outside thrusts of two lower edge reinforcing bars 22 of steel bar girder 20, therefore, these two thrusts can not be delivered on bed die 30 by junction button 10 and make bed die 30 produce stretcher strain and affect support effects, also connection bed die 30 can not be made to cause difficulty because bearing shearing force to follow-up dismounting with the screw 40 of junction button 10.
Below the making of detachable bed die formula steel bar truss floor support plate of the present utility model and use procedure are introduced:
1, utilize reinforcing bar to build skeleton, and form steel bar girder 20 by welding.
2, by bed die 30 machine-shaping, adopt plant equipment automatic drilling, junction button 10 is connected by screw 40 with the bed die 30 of having holed.
3, the steel bar girder 20 of machine-shaping is compressed by external force, two lower edge reinforcing bar 22 distances are narrowed, until can enter in the rectangular channel 11 of junction button 10, two lower edge reinforcing bars 22 of steel bar girder 20 utilize self resilience, automatic clamping is located in two draw-in grooves 12 of junction button 10, and detachable bed die formula steel bar truss floor support plate completes.
4, detachable bed die formula steel bar truss floor support plate is laid on appointed area, carries out concreting, after building by steel bar girder 20 for bed die 30 provides without support stiffness, carry concrete gravity and load of constructing by being threaded of screw 40 and junction button 10.
5, after concrete setting reaches requirement, with electric drill, the screw 40 on bed die 30 is exited, then bed die 30 is removed.
In order to make bed die 30 can provide uniform support force to concrete, often row's junction button 10 is evenly arranged along the axial direction of lower edge reinforcing bar 22.
As shown in Figure 1, for making two lower edge reinforcing bars 22 of the steel bar girder 20 being in compressive state can facilitate, enter smoothly the rectangular channel 11 of junction button 10 to be fastened in two draw-in grooves 12, the notch place of the rectangular channel 11 of junction button 10 offers the guiding surface 13 for being imported by lower edge reinforcing bar 22 in rectangular channel 11.
