Abstract
The utility model relates to a precast floorslab beam bottom-sealing device, comprising two precast floorslabs forming a gap as large as beam position, a square formwork arranged between the gap of the two precast floorslabs to seal the gap bottom, a sealing body arranged between the formwork and the two precast floorslabs, a transverse rod arranged below the formwork, a supporting upper rod arranged above the gap of the two precast floorslabs corresponding to the transverse rod, and a connector that passes through the transverse rod, the formwork, the sealing body, and the supporting upper rod to make the transverse rod lean tightly against the supporting upper rod and to make the formwork press the sealing body to close contact the precast floorslabs. With the fixed connector, the supporting upper rod and the transverse rod make the formwork and the sealing body close contact the precast floorslabs. Therefore, a support rod does not need to be arranged, and the leakage of the cement mortar is avoided.
Description
Technical field
The utility model relates to a kind of precasting floor joist position back cover structure, relates in particular to a kind ofly can not cause construction site operation inconvenience, and can avoid the precasting floor joist position bottom closing device of cement mortar spill and leakage.
Background technology
Present reduction and convenience for the building operations time, pre-casting method has become one of building construction method that widely uses, because pre-casting method is that beam, post and the floor that prior precasting is good directly is transported to assembled on site, grouted solid gets final product, therefore the site operation activity duration can significantly be saved, in the place that the floor level is had relatively high expectations, also can utilize the level of precasting floor to require to reach the problem of the horizontal accuracy deficiency of the floor of avoiding site operation in advance.
Tradition precasting floor is when applying, mostly be that the precasting floor is seated on the support cylinder, again with the beam body of space, the interval concrete perfusion between two precasting floors with the making building, mostly traditional method is to be provided with template die in the bottom, interval of two precasting floors, this template die then is to utilize support bar to be supported, mostly this support bar is upright and is located at down on the first floor plate, but this way not only can cause in upright be provided with in the support bar floor movable construction worker's inconvenience, and if support bar upright establish apply bad, also can cause template die can't seal space, interval between two precasting floors, when causing the cement mortar perfusion, the gap location that can be joined by template die and precasting floor produces spill and leakage, even the problem that drops of template.
The utility model content
In order to overcome weak point of the prior art,
Main purpose of the present utility model is to provide a kind of can not cause construction site operation inconvenience, and can avoid the precasting floor joist position bottom closing device of cement mortar spill and leakage.
In order to reach above-mentioned utility model purpose, the utility model system takes following technological means to be reached, and precasting floor joist wherein provided by the utility model position bottom closing device includes:
Two precasting floors are formed with the space, interval of beam position size between the precasting floor;
Template die is square body, and the gap, interval that is arranged between the precasting floor is sealed to incite somebody to action bottom, space, interval, and it is provided with the perforation in relative precasting floor interbody spacer space;
Seal is arranged between template die and the precasting floor, and it is provided with the perforation with respect to the template die perforation;
Cross bar is arranged on the template die below, can be provided with the perforation with respect to the template die perforation on it;
Support upper boom, be arranged at the top, space, interval that is arranged on the precasting floor with respect to cross bar, can be provided with perforation on it with respect to the template die perforation;
Connector, the perforation that runs through cross bar, template die, seal and support upper boom to be will support upper boom and cross bar is close to mutually, force template die to oppress seal simultaneously and the precasting floor connects airtight.
By fixing of connector, make support upper boom and cross bar template die and seal can be adjacent to the precasting floor closely, so do not need to be provided with support bar, also do not have the problem generation that cement mortar is leaked.

The specific embodiment
Please extremely shown in Figure 3 referring to Fig. 1, precasting floor joist of the present utility model position bottom closing device includes:
Two precasting floors 10 are formed with the space, interval 11 of beam position size between the precasting floor 10;
Support upper boom 50, be arranged at 11 tops, space, interval that are arranged on precasting floor 10 with respect to cross bar 40, can be provided with perforation 51 on it with respect to template die 20 perforation 21;
The employed connector 60 of present embodiment is a rope body, this rope body can be article such as iron wire, the rope made of hemp, and this rope body is directly walked around and is supported upper boom 50 and cross bar 40 so that both are close to mutually, and seal 30 can be soft sealing materials such as rubber, flexible plastic, silica gel.
The utility model is when using, at first seal 30 is arranged on the interval space 11 of precasting floor 10 lower ends with 10 on sealing precasting floor, again template die 20 is arranged on seal 30 downsides with fixing seal body 30, utilize cross bar 40 to be arranged on template die 20 belows, run through cross bar 40 from lower to upper by connector 60, template die 20, the perforation 41 of seal 30 and support upper boom 50,21,31,51, and tie up to be located at and support on the upper boom 50 so that support upper boom 50 is close mutually with cross bar 40, and then compressing template die 20, force template die 20 compressing seals 30 with after connecting airtight with precasting floor 10 simultaneously, can be by space, the interval 11 top concrete perfusions of 10 on precasting floor to form the beam body of 10 on precasting floor.
Please referring to shown in Fig. 1,4, treat that concrete is stiff after, after rigid connector 60 cut off, get final product after removing cross bar 40, template die 20, seal 30 and supporting upper boom 50.
Please referring to shown in Fig. 5,6, connector 60 can also be the combination of bolt and nut, and to support upper boom 50 close mutually with cross bar 40 to force whereby, and then compressing template die 20, force template die 20 compressing seals 30 to connect airtight with precasting floor 10 simultaneously, it is same as the previously described embodiments to apply mode.
