Abstract
The utility model discloses a preformed hole formwork fixing device for a bare concrete floor, and relates to a construction formwork. The preformed hole formwork fixing device for the bare concrete floor comprises a floor bottom formwork and a split bolt, wherein the split bolt comprises a gasket, a nut and a screw; a preformed hole formwork is arranged above the floor bottom formwork; the screw penetrates in the floor bottom formwork and the preformed hole formwork and is perpendicular to the floor bottom formwork; a plurality of square timbers are arranged between the preformed hole formwork and the gasket II at the upper end of the screw, are symmetrically arranged on two sides of the screw, and are parallel to the floor bottom formwork; the preformed hole formwork is fixed by using the split bolt through the square timbers; an adhesion sponge strip is arranged between the preformed hole formwork and the floor bottom formwork; and slurry is prevented against leaking from seams of the formwork. Reliability on formwork supporting of a preformed hole of the floor with the bare concrete structure can be guaranteed; and deviation on the preformed hole of the floor in a construction process is avoided.
Description
Technical field
The utility model relates to a kind of building construction formwork, is specifically related to plain concrete floor preformed hole fixing templates.
Background technology
In housing construction, floor prepared hole is frequent thing, but the requirement of plain concrete floor preformed hole must be strict, do not allow hole dislocation, hole not just etc. phenomenon occur; Even if produce spillage phenomenon, also do not allow, spillage can directly affect the impression quality of the clear-water concrete of building, and therefore, handling plain concrete floor preformed hole well, to prop up modulus problem extremely important.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides plain concrete floor preformed hole fixing templates.
The utility model is to adopt following technical scheme to realize: a kind of plain concrete floor preformed hole fixing templates, it comprises bottom of the building template and split bolt.Described split bolt comprises pad, nut and screw rod.It is characterized in that: described bottom of the building template top is provided with preformed hole template; Described screw rod is through bottom of the building template and preformed hole template, and screw rod is mutually vertical with bottom of the building template.Between described preformed hole template and the pad II of screw rod upper end, the many lumps of wood are housed; Described lumps of wood symmetry is arranged on the both sides of screw rod.
Further: between described preformed hole template and bottom of the building template, be equipped with and add sticky sponge strip.
The described lumps of wood is two.
The beneficial effects of the utility model are: simple in structure, easy to make; The formwork that can guarantee preformed hole on clear-water concrete structure floor is reliable, avoids the floor preformed hole in work progress to produce deviation; Avoided hole dislocation, hole not just etc. phenomenon occur.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1, floor bottom mould, 2, add sticky sponge strip, 3, pad I, 4, nut I, 5, screw rod, 6, concrete floor, 7, preformed hole template, 8, the lumps of wood, 9, nut II, 10, pad II.
The specific embodiment
As shown in Figure 1, plain concrete floor preformed hole fixing templates, it comprises bottom of the building template 1 and split bolt.Described split bolt comprises pad, nut and screw rod 5.It is characterized in that: described bottom of the building template 1 top is provided with preformed hole template 7.Between preformed hole template 7 and bottom of the building template 1, be equipped with and add sticky sponge strip 2, or cotton strap, wide adhesive tape etc., can also after formwork, scrape mortar stuff up a crack, prevent from producing spillage phenomenon between preformed hole template 7 and bottom of the building template 1.Described screw rod 5 is through bottom of the building template 1 and preformed hole template 7, and screw rod 5 is mutually vertical with bottom of the building template 1.Two lumps of wood 8 are housed between the pad II 10 of described preformed hole template 7 and screw rod 5 upper ends, and the lumps of wood 8 symmetries are placed on the both sides of screw rod 5.
During use, between preformed hole template 7 and bottom of the building template 1, be equipped with and add sticky sponge strip 2, after the position of preformed hole template 7 and bottom of the building template 1 places, then screw rod 5 is through bottom of the building template 1 and preformed hole template 7, when the protruded length at screw rod 5 two ends is about equally time, at the two ends of screw rod 5, wear respectively pad erection bolt.Then two lumps of wood 8 symmetries are placed on to the both sides of screw rod 5, the lumps of wood 8 positions tight a bolt after putting well, and then levelling makes preformed hole template 7 installation sites meet the requirement of design to preformed hole.
