In order to make the technical solutions of the present invention better understood, the present invention is further described in detail below with reference to the accompanying drawings and examples.
The embodiment of the invention provides a simple and effective floor construction quick support scheme, in particular to a reusable floor construction quick support structure with once-introduced equipment, aiming at the problem that the introduction of process equipment can be carried out only after concrete is completely cured and a scaffold and a bottom template are removed in the prior art.
As shown in fig. 1 and 2, the support structure is arranged between a surface layer 1 at the bottom of the room, which may be a surface layer of a floor layer, and a floor slab bottom formwork 2 at the top of the room. The supporting structure comprises a hollow frame, the frame comprises a vertical part and a first horizontal part, the vertical part is attached to a wall and arranged at the top of the vertical part, the bottom of the vertical part is in contact with a surface layer, and a floor slab bottom template is laid at the top of the first horizontal part.
Therefore, the hollow frame is used as a supporting structure to support the construction load of the upper floor slab and reserve a space for a lower room, so that the process equipment can be introduced in advance before the concrete floor slab is poured. Of course, the device may be introduced before the frame is placed, or the device may be introduced after the frame is placed.
In this embodiment, in order to better support the load of the upper floor slab construction, it is preferable that the frame is a steel frame. Accordingly, the vertical portion and the first horizontal portion constituting the steel frame are also made of steel material.
Specifically, the vertical portion includes a plurality of vertically disposed steel columns 31 (specifically, section steel columns), and the steel columns 31 are arranged close to a wall. As shown in fig. 1 and 2, assuming that there are four walls in a room, namely, a wall 1, a wall 2, a wall 3 and a wall 4 in this order, and the wall 1 and the wall 2 are oppositely arranged, and the wall 3 and the wall 4 are oppositely arranged, the steel columns 31 are arranged closely to the walls 1 to 4, and the steel columns 31 are arranged to be through-high under the condition that the space of the floor bottom formwork 2 is sufficiently reserved. First horizontal part includes the girder steel 32 of many level settings, just the top and the floor bottom template 2 contact of girder steel 32.
As one aspect of the present invention, if the span of the room is small, the steel columns 31 in the vertical part may be disposed only at each wall corner in the room, and both ends of the steel beam 32 in the first horizontal part are fixed to the tops of the adjacent steel columns 31 by connectors, thereby constituting a steel frame.
As shown in fig. 3 and 4, the connection includes pre-assembled gusset plates 33 and bolts 34, with the gusset plates 33 pre-assembled in different orientations on top of the steel columns 31. Preferably, the gusset plate 33 is made of angle steel, and one limb of the angle steel is connected with the steel column 31, and the other limb of the angle steel is connected with the steel beam 32 through a bolt 34.
As another aspect of the present invention, if the room has a large span, and steel columns can be added between adjacent steel columns to reduce the supporting span without affecting the introduction of equipment, the steel columns 31 in the vertical part can be disposed at each corner in the room and in the middle of the adjacent corners in the room, and then both ends of the steel beam 32 in the first horizontal part are also fixed on the top of the adjacent steel columns 31 by connectors, which also include pre-installed node plates 33 and bolts 34.
In addition, in order to enhance the overall stability, the frame may further include a second horizontal portion provided at a bottom of the vertical portion, the bottom of the second horizontal portion being in contact with the surface layer 1. Preferably, the second horizontal portion is also made of steel material.
As shown in fig. 2, the second horizontal portion includes a plurality of steel beams 32 horizontally disposed; the steel beams 32 in the second horizontal section are secured at both ends to the bottom of the adjacent steel columns 31 by connectors, which also include pre-assembled gusset plates 33 and bolts 34.
It should be noted that, a steel beam may be provided between the bottoms of every two adjacent steel columns, or a part of adjacent steel columns may be selected according to actual conditions, and a steel beam may be provided between the bottoms.
In practical application, the steel frame can be arranged before equipment is introduced or after the equipment is introduced, and is determined according to the practical condition of the equipment introduction so as to ensure the space for transporting and arranging the equipment. And because the steel frames are connected through the node plates by adopting bolts, after the floor slab on the upper part of the supporting structure is constructed and maintained, the steel frames can be quickly dismantled for use in other construction rooms, thereby improving the economy to the maximum extent.
Of course, the steel columns and the steel beams can be spliced into different lengths according to the field requirements. Specifically, as shown in fig. 6, each steel column 31 may include a plurality of sub-steel columns connected end to end and arranged in a line, and as shown in fig. 5, each steel beam 32 may include a plurality of sub-steel beams connected end to end and arranged in a line. The adjacent sub-steel columns and the adjacent sub-steel beams can be fixed through connecting pieces, and the connecting pieces also comprise preassembled node plates 33 and bolts 34.
In this embodiment, steel column and girder steel can be according to certain modulus, according to different cross-sectional dimensions and the multiple specification of length design preparation, and steel column and girder steel can splice into different length through the gusset plate to satisfy on-the-spot demand. The gusset plate can also be designed into various specifications, but in order to be convenient to use and avoid frequent replacement, a small number of specifications can be designed according to larger load to cover various different conditions. In construction, the specifications of the steel beam, the steel column and the gusset plate are selected by calculation according to the construction load of the floor slab. Meanwhile, the arrangement distance of the steel columns can be adjusted according to the construction load of the concrete floor slab.
The inventor also finds that when the pouring of the concrete floor slab of the factory building adopts the traditional temporary support mode of erecting a scaffold and the like, in the process of introducing process equipment after the concrete is completely cured and the scaffold and the bottom template are dismantled, a hoisting route needs to be planned, and a hoisting hole, a transportation channel and the like are arranged, so that a large amount of manpower and material resources are consumed.
In order to overcome the above problems, in the embodiment of the present invention, as shown in fig. 1, the supporting structure further includes a shelf 35 whose bottom is in contact with the surface layer 1 for placing the process pipe and the process equipment, thereby facilitating the management and transportation of the process equipment and the process pipe, improving efficiency and increasing safety.
Specifically, as shown in fig. 7 and 8, the shelf includes a plurality of bottom plates 351 arranged at intervals, and a detachable support 352 arranged on each bottom plate 351, wherein the support 352 can be installed at different positions or removed as required. The support 352 includes a sub-support for isolating the process equipment and a sub-support for supporting the process pipe, and the specific structures of the two sub-supports are not limited in the present invention as long as the functional requirements for isolating the process equipment and supporting the process pipe can be satisfied.
In summary, the invention arranges a plurality of temporary supporting steel columns beside the peripheral wall body in the room of the nuclear power plant to be constructed, node plates are pre-installed on the tops of the steel columns, steel beams are connected between adjacent steel columns through the node plates to form a steel frame, then a floor bottom formwork is laid on the steel beams of the steel frame, and concrete floors are poured, so that the steel frame system formed by the steel beams and the steel columns can effectively support the load of upper floor construction, thereby replacing the function of the traditional scaffold, the steel columns in the steel frame are arranged against the wall, the steel beams are arranged against the floor bottom and the surface layer, so the main space in the room is not influenced, the advance introduction of equipment can be realized without waiting for the complete maintenance of concrete and the dismantling of the scaffold and the bottom formwork, thereby shortening the construction period, and the structural arrangement is simple and reasonable, and the on-site rapid assembly can be realized, And the dismounting has strong flexibility and reusability.
