Description
Technical field
The utility model relates to concrete blinding construction work technical fields, and in particular to a kind of fixed dress of vertical plank sheathing
It sets.
Background technique
In form work engineering construction at present, to guarantee concrete construction quality, commonly uses plank sheathing, glued board etc. and replace steel form
And other higher templates of cost, and template be connected and fixed be in form work engineering quality control emphasis.Board bottom plank sheathing 13 with
Beam side rail template 10(right angle) it is fixed when, conventional to be fixed using iron nail, ailing tool is currently mainly used hand-held hammer and taps nail
Enter.When beam steel 12, which is bound, to be completed and need to reinforce beam side rail template 10 again, hand-held hammer is influenced by beam steel 12
It can not protrude into beam and use.Using traditional handicraft, beam steel 12 can only be hung out, to reduce working efficiency, be increased into
This, and 12 mass of beam steel is impacted, the prior art can not solve above-mentioned technical problem.
Utility model content
Purpose of the utility model is to solve need in the prior art when beam steel bar colligation is completed to side template
When being reinforced again there are the problem of, provide a kind of vertical wooden model board fixer that structure is simple and convenient to operate.
In order to achieve the above object, the utility model uses a kind of following technical scheme: vertical wooden model board fixer, packet
The oversheath across beam steel is included, the both ends of oversheath are open, fixed on the inside of one end of oversheath that inner sheath, inner sheath are housed
Be provided with stretching hammer, stretch and is set with spring, and the end thereof contacts of one end of spring and inner sheath on hammer, the other end of spring with
The end head for stretching hammer is fixed, and is also equipped with steel nail on the inside of the other end of oversheath.
Further, the end head for stretching hammer is welded with circular magnet plate, between circular magnet plate and inner sheath one end
It stretches and spring is housed on hammer.
Further, the extension end for stretching hammer is equipped with handle.
Further, one end of inner sheath and one end of oversheath are concordant.
Further, oversheath is the steel pipe casing of DN20mm~DN40mm.
Further, inner sheath is the steel pipe casing of DN15mm~32mm.
Further, the outer diameter for stretching hammer is 6 mm~20mm.
Further, spring is compressed spring.
The utility model compared with the existing technology, has the advantages that the vertical plank sheathing of the utility model is fixed
Device stretches hammer by installing in the inner sheath on the inside of one end of oversheath, stretches and covers and shoot on hammer, one end of spring with it is interior
The end thereof contacts of sheath, the other end of spring are fixed with the end head for stretching hammer, when pulling stretching hammer outward, stretch hammer band
Dynamic spring-compressed stretches hammer under spring force when moment, which unclamps, stretches hammer, will be located at the steel nail for stretching hammer tip head
Template is hammered into after pop-up oversheath.Solving, which is influenced hand-held hammer by beam steel, can not protrude into the drawbacks of using in beam steel.This reality
It is simple and convenient to operate, is simple to manufacture with new structure, had many advantages, such as low in cost, convenient and practical, easily operated.
The stretching hammer tip head of the utility model is welded after passing through spring end with circular magnet plate, before use, by steel
Nail is put into sheath (steel nail tip is outwardly), is influenced by circular magnet plate magnetic force, and iron nail pedestal firmly attracts with magnet plate, thus
It will not fall and position is fixed.When pulling stretching hammer, spring-compressed, circular magnet plate and steel nail are unclamped with spring movement
When stretching hammer, under the action of elastic force, stretching hammer and circular magnet plate is being influenced to push iron nail by spring force, to tap iron
Tail portion is followed closely, steel nail is hammered into plank sheathing.
The extension end of the stretching hammer of the utility model is equipped with handle and facilitates pulling.
The utility model in practical applications, obtains preferable effect, can be widely applied in formwork reinforcement, steel nail nail
When entering plank sheathing, by plank sheathing friction effects, and the elastic force of spring is enough to overcome plank sheathing drag effects, so that steel nail be followed closely
Enter in plank sheathing.Therefore, it using the utility model tool, can be hung out to avoid by the steel reinforcement cage placed, improve construction effect
Rate reduces cost, and effectively reduces the injury to plank sheathing.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-5, a kind of vertical wooden model board fixer, the oversheath 1 including passing through beam steel 12, oversheath 1
It is fixed on the inside of one end of oversheath 1 that inner sheath 3 is housed for the steel pipe casing of DN20mm~DN40mm, inner sheath 3 be DN15mm~
The steel pipe casing of 32mm, it is practical to be adjusted according to the internal diameter of oversheath 1, and the length of oversheath 1, the length of inner sheath 3 are according to reality
Border operating condition determines.One end of inner sheath 3 is concordant with one end of oversheath 1, and inner sheath 3 is provided with stretching hammer 2, stretches hammer 2
Outer diameter is 6 mm~20mm, stretches and is set with spring 4 on hammer 2, and spring 4 is compressed spring, and the diameter of spring selects 8mm-22mm,
It is adapted with the outer diameter for the outer diameter for stretching hammer 2.The length of spring is 300 or so, guarantees enough deformation quantities to reach steel nail nail
Enter the power of plank sheathing, and the end thereof contacts of one end of spring 4 and inner sheath 3, the end head 7 for stretching hammer 2 passes through the end of spring 4
After be welded with circular magnet plate 5, the extension end for stretching hammer 2 is equipped with handle 9.Steel nail 6 is also equipped on the inside of the other end of oversheath 1.
It is symmetrically arranged on the outside of the end of oversheath 1 equipped with four position lines 8, position line 8 and the steel nail being arranged in beam side rail template 10
11 flush of the position line, ensure that steel nail hammers into positional accuracy.
When work, steel nail 6 is put into oversheath 1, under magneticaction, the steel nail head of steel nail 6 is put into circular magnet plate 5
On, under magneticaction, it ensure that the position of steel nail 6 stablizes not deviate and do not fall.It later will be equipped with the oversheath 1 for stretching hammer 2
After beam steel 12, keep the position line 8 on oversheath 1 corresponding with the steel nail position line 11 in beam side rail template 10 concordant,
It determines the position that steel nail 6 hammers into, one is held by the handle 9 for pulling and stretching hammer 2 later, circular magnet plate 5 and steel nail 6 are with spring
4 deformation direction is mobile, will stretch after hammer 2 draws on earth, and quickly unclamp and stretch hammer 2, under spring force, stretch hammer 2 and
Circular magnet plate 5 is influenced to push steel nail 6 by spring force, and steel nail 6 is hammered into beam side rail template 10.
Feasibility analysis
When steel nail 6 is entered beam side rail template 10 by spring force, the resistance of beam side rail template 10, resistance and steel nail will receive
6 depth is directly proportional and proportionality coefficient is k(according to test of many times, measures k=2), according to (wherein F is resistance, and x is steel nail 6
Hammer into depth) spring-like model.
The mean resistance F that steel nail 6 is subject in the whole process are as follows:
The function W that steel nail 6 overcomes resistance to doFAre as follows:
The elastic potential energy W of spring 4 are as follows:(wherein k1For 4 spring constant of spring, x1For the deformation of spring 4
Measure) k is taken according to test1=15N/m。
Conclusion: then W > WF, elastic potential energy > nail overcomes the function that resistance is done, and magnetic force in the process is far smaller than bullet
Property potential energy, can be neglected, nail can be ordered in plank sheathing.
