Description
Technical field
The utility model is related to building field, particularly a kind of floor sealing hole sizing gasifying device.
Background technology
When cast-in-place structural is constructed in the past, concrete dabbing.Before sealing hole, first by hole periphery dabbing,
Hole periphery base cleaning is clean, and dabbing is shaped as tubaeform.The formwork erection that Normal practice is blocked to reserved opening is main
Steel pipe jacking can be taken to support and hang two kinds of mould.Relatively low for story height, it is easy to carry out hanging hole as supporting using steel pipe,
Can take this approach and be installed；Higher for story height, it is not easy to carry out hanging hole as supporting using steel pipe, can adopts
It is taken at floor topping placement short steel pipes or reinforcing bar is connected using iron wire with floor slab bottoms template, formation is hung mould and constructed.
Easily there are the quality problems such as running pulp, the mould that rises in both the above constructing device, and the mould phenomenon that rises is serious even
Needs are plastered just now after picking chisel and meet construction requirement；And may take off after not etc. not caused to plaster due to workman's construction level
Fall, being normally carried out to operation under being unfavorable for；Then need to pick chisel during finishing, repair, cause structure and unnecessary waste is destroyed,
How to make that floor sealing hole is convenient and swift, accelerating construction progress, ensure concrete while reduce labour intensity, save material
Impression quality is extremely important.Therefore, the improvement of floor sealing hole sizing gasifying device and innovation are the problems of current urgent need to resolve.
Content of the invention
For above-mentioned situation, it is the defect for solving prior art, the purpose of the utility model is exactly to provide a kind of floor hole
Mouthful closure sizing gasifying device, can easily there is running pulp in effectively solving existing apparatus, rise mould, the low problem of high cost, efficiency.
The technical scheme that the utility model is solved is that, including steel form, bolt group and nut, bolt group passes through plate stress steel
Muscle is welded and fixed, and steel form is hollow quadratic shape, is arranged with through hole on corner, and steel form via through holes are sleeved in bolt group,
And fix through nut.
The utility model standardization level is high, can factorial praluction, be repeatedly used in turn, convenient to assemble and disassemble quick, change
Traditional sealing hole hangs the mode of mould, has saved raw material, solid and reliable, guaranteed, the environmental protection of safety；Improve coagulation
While native aesthetic quality, it is ensured that construction quality, it is the innovation on floor sealing hole sizing gasifying device.

Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Be given by Fig. 1-6, the utility model includes steel form, bolt group and nut, bolt group 1 passes through plate steel bar stress 4
It is welded and fixed, steel form 3 is hollow quadratic shape, is arranged with through hole on corner, and 3 via through holes of steel form are sleeved in bolt group 1,
And fix through nut 2.
In order to ensure using effect, described bolt specification is M14, and length is slab thickness+80mm；3 size of steel form
For 300mm × 300mm, thickness is 6mm, wall thickness 100mm.
Described bolt group has 4 bolts per group, and the distance of bolt-center to 3 inwall of steel form is 50mm.
Described nut 2 is double nut.
Welded reinforcement 9 in described bolt group 1, reinforcing bar 9 are long 50mm, the HPB300 reinforcing bar of a diameter of 8mm, are arranged on spiral shell
In the bolt group of female 2 top.
Pad 10 is provided between described steel form 3 and nut 2.
When the utility model is used, carry out according to the following steps：
1. perforate, pre-embedded bolt group 1, exposed bolt head plastic sheeting bag are shifted to an earlier date on request according to 8 position of live hole
Firmly it is protected by；
2. steel form 3 shifts to an earlier date brushing releasing agent after perforate, and steel form 3 is enclosed within bolt group 1；
3. by nut 2 in bolt group 1；
4. the closure at unwrapping wire hole 8 requires construction in strict accordance with flooring antiseep process node, and formwork erection, reinforcing bar are extensive
After the completion of multiple, notify mixing plant micro-expanding agent to be mixed according to the concrete of a grade higher than the concrete of former floor label and sealed
Stifled, blocked in the area 5 of closure first, secondary plugging area 6 successively；
5., after concrete enters mould, should pour dense, afterwards mend reserved opening concrete should be slightly above original surface also can be with former table
Face one is flat.Benefit concrete is combined with former concrete and is answered closely afterwards, and surface should be compacted floating.Treat that intensity reaches 1.2N mm2After water
Maintenance or covering with plastic film maintenance；
6., after the dismounting of steel form 3,7 outside bolt head of floor is exposed to 7 absolute altitude of floor with angle grinder cutting；
7. cleaning surface dirt and rubbish, mend floor scope three times JS water-repellent paints of brushing rear.Should cover during application
In former concrete 100mm, and brushing should be layered.Should treat during brushing second time that ground floor water-repellent paint dries that to form diaphragm laggard
OK, and by parity of reasoning.Forbid that pedestrian tramples after water-repellent paint brushing, it is necessary to do appropriate maintenance.
Service condition of the present utility model is, first, when 7 template of floor is installed, in advance in the template for installing with red
Paint is marked out and needs position of opening（That is 1 position of bolt group）, needed before assembling reinforcement to output hole in advance reserved, broken after perforate
Bits will be cleared up in time.After 3 size of steel form is determined, in advance steel form 3 is cut, and position of opening is indicated on steel form 3,
Standby with bench drill perforate.Floor lower plane is installed on after the 3 brushing releasing agent of steel form that makes, nut 2 is tightened（Reach rule
Model is required）.Standby in the HPB300 reinforcing bar 9 of bolt appropriate position welding 50mm length, a diameter of 8mm, to ensure bolt absolute altitude.
After the completion of 4 colligation of plate muscle, pre-embedded bolt group 1 need to be with 7 levels reinforcing bar spot welding of floor to guarantee Bolt sizes, position and mark
High；During casting concrete, exposed bolt head beyond floor absolute altitude is protected with plastic sheeting in advance, in order to avoid concreting
When uncertain factor to bolt screw thread pollute, cause follow-up nut install when go wrong.When hole need to block, bolt will be rolled in
Plastic sheeting on head is removed；Casting concrete, when the age of concrete code requirement is reached, after removing steel form 3, is ground with angle
Machine cuts off exposed bolt head beyond floor absolute altitude.
The utility model device is applied to the closure of 200mm*200mm reserved opening.Using this device construction, convenient fast
Prompt, accelerating construction progress, it is ensured that while construction quality, improve concrete impression quality, can effectively meet specification quality will
Ask and have preferable aesthetic quality.Can avoid hanging mould in conventional construction and running pulp occur, the quality problems such as the mould that rises.In addition
Can achieve to improve the purpose of operating efficiency, steel form repeatedly can be used in turn, and be easy to operative, it is to avoid cause because rising by mould
Pick chisel and secondary plaster；As hole area is less, pick that chisel gets up to be difficult, secondary plastering is more difficult to；Workman's construction level,
It also avoid due to secondary plaster be likely to result in come off, hollowing etc., be the innovation on floor sealing hole sizing gasifying device, tool
There is good economic and social benefit.
