Abstract
The utility model discloses an LPM hollow die construction anti-floating structure. The anti-floating structure comprises a floor formwork well installed according to the drawing requirement, and the floor formwork is paved with bottom steel bars in a criss-cross mode. A holed anti-floating steel belt with the two ends provided with through holes presses and covers the joints of the bottom steel bars, long screws penetrate through the through holes and are fixed in the floor formwork, a concrete cushion block and an LPM hollow die are placed on the bottom steel bars in sequence, and at least two special steel wires penetrate through the bottom steel bars and bundle the LPM hollow die. The LPM hollow die construction anti-floating structure is simple in manufacturing technology, convenient and flexible to construct, low in manufacturing cost, and capable of increasing the construction speed and shortening the construction period. The method can effectively solve the problem that the LPM hollow die floats in the concrete pouring process, the floor construction quality is guaranteed, the construction applying prospects are wide, and the LPM hollow die construction anti-floating structure can be popularized and used during the LPM hollow die construction.
Description
Technical field
the utility model relates to a kind of LPM hollow mold construction float Structure, belongs to technical field of building construction.
Background technology
lPM hollow building cover is in recent years cast-in-place concrete hollow building roof form of structure newly developed, compared with traditional beam and slab type superstructure, LPM hollow floor structure from heavy and light, the feature such as span is large, shock resistance is strong, sound insulation, good heat-insulation effect.This kind of superstructure, floor clear height increases, and can make full use of architectural space, reduces floor design height, facilitates the layout of all kinds of pipelines, greatly reduces reinforcing bar, concrete material consumption, thereby reduces comprehensive cost.
lPM hollow mold is from heavy and light, in work progress, easily because concreting method is improper or fixing means is not in place etc., factor floats, cause floor to occur cavity, leak the mass defects such as muscle, therefore, it is the key that LPM hollow building cover is extensively promoted that the anti-floating problem of LPM hollow building cover solves.Conventional anti-float method is to be directly fixed in template with iron wire and thumb screw after hollow mold has been put, and the method constructing operation speed is slow, anti-floating effect is undesirable, and form removal inconvenience easily makes the breakage of floor template face.
Summary of the invention
the purpose of this utility model is: a kind of LPM hollow mold construction float Structure is provided, and its manufacture craft is simple, easy construction, flexible, and low cost of manufacture, can accelerate speed of application, and the reduction of erection time, to overcome the deficiencies in the prior art.
the technical solution of the utility model:
a kind of LPM hollow mold construction float Structure, this float Structure comprises mounted floor template by drawing, on floor template, be equipped with the end reinforcing bar intersecting in length and breadth, be provided with the anti-floating steel band gland with holes of through hole at two ends at the interface point place of end reinforcing bar, and pass through hole by long spiro nail and be fixed in floor template, on end reinforcing bar, place successively mixed earth cushion block and LPM hollow mold, then adopt at least special steel wire of twice twice to pass end reinforcing bar and tie up LPM hollow mold.
in above-mentioned LPM hollow mold construction float Structure, described special anti-floating steel band with holes middle part is convex structure.
in above-mentioned LPM hollow mold construction float Structure, described special steel wire is the annealing black wire forming through processes such as cold-drawn, heating, constant temperature, insulations, and diameter is 1mm～5mm.
owing to having adopted technique scheme, compared with prior art, muscle special steel strip intensity of the fixing end in the utility model is high, and adopt long spiro nail to fix, maximum limitation is utilized the build-in force of slab form and screw, fixed form is reliable, and long spiro nail has not needed to penetrate slab form, the mounting or dismounting of aspect anti-floating steel band with holes, and can not destroy slab form, fixed core model's steel wire processed adopts special process moulding, more soft compared with ordinary steel wire, binding speed is faster, space is less, to core without damage, effect is very obvious, in addition, special steel wire end bundle pin possibility is lower, reduce gluten colligation security risk, by being located at the mixed earth cushion block in the middle of LPM hollow mold and end reinforcing bar, more the fixed effect of LPM hollow mold is better, prove that in actual applications the method can solve LPM hollow mold On The Floating in concreting process effectively, guarantee floor slab construction quality, future in engineering applications is wide, can in the construction of LPM hollow mold, promote the use of.
Accompanying drawing explanation
accompanying drawing 1 the utility model construction schematic diagram;
the structural representation of special anti-floating steel band with holes in accompanying drawing 2 the utility model.
reinforcing bar, 6-LPM hollow mold, 7-long spiro nail, the mixed earth cushion block of 8-at the bottom of being labeled as in accompanying drawing: 1-anti-floating steel band with holes, 2-through hole, the special steel wire of 3-, 4-floor template, 5-.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is that adjustable to face limit supporting method constructed according to following, this LPM hollow mold construction anti-float method is floor template, it is an entirety that the end reinforcing bar of installing in length and breadth and LPM hollow mold interfix, its concrete construction method comprises that end reinforcing bar is fixed on floor template and hollow mold is fixed on two parts on end reinforcing bar, wherein end reinforcing bar fixing means be adopt special anti-floating steel band with holes at gland at reinforcing bar knot point place, the end in length and breadth, adopt again Electric portable drill that long spiro nail is penetrated to the hole of anti-floating steel band with holes and hammers in floor template, realizing end reinforcing bar is fixed on floor template, and hollow mold fixing means is to adopt at least special steel wire of twice to pass end reinforcing bar and tie up LPM hollow mold, and in LPM hollow mold and the middle concrete pad that is covered with of end reinforcing bar, thereby realizing LPM hollow mold is fixed on end reinforcing bar.
the LPM hollow mold float Structure forming according to said method, as shown in the figure: this float Structure comprises mounted floor template 4 by drawing, on floor template 4, be equipped with the end reinforcing bar 5 intersecting in length and breadth, be provided with anti-floating steel band 1 gland with holes of through hole 2 at two ends at the interface point place of end reinforcing bar 5, and be fixed in floor template 4 through through hole 2 by long spiro nail 7, on end reinforcing bar 5, place successively mixed earth cushion block 8 and LPM hollow mold 6, then adopt at least special steel wire 3 of twice twice pass end reinforcing bar 5 and tie up LPM hollow mold.
wherein the through hole 2 of special anti-floating steel band 1 with holes is located at the two ends of anti-floating steel band 1 with holes, and anti-floating steel band with holes 1 middle part is convex structure, length and width are of a size of 15mm × 190mm, special steel wire 3 is the annealing black wires that form through processes such as cold-drawn, heating, constant temperature, insulations, and is directly 1mm.
