Abstract

The invention relates to a device to fasten template, especially keel fastening device of branch water template. Keel is the section bars with upper and down through connecting clearance. And the temperate layering is pressed on the brim of neighbor template. Pressing installation bracing is connected at the down part of the layering and perforating the clearance of keels, and is fixed at the down part of keels. The invention has simple structure, and could lower intensity of labor. And the working efficiency would be sharply increased.

Description

The device of formboard fastening

Technical field

The invention belongs to building unit, particularly the keel fastener of plain form.

Background technology

The job practices of traditional plain form is with long flitch, digs the higher keel of glacing flatness, and wooden form is layered on the keel, pieces together neat seam, and stickfast and is sticked gummed paper at seam crossing on rough ground, in case concrete leaks down from seam crossing.Because the flitch easy deformation, dig qualified keel and need waste a large amount of timber, and nail can damage the wooden of keel and template, more caused the huge waste of builing industry timber; The edge of template need cut very concordantly, could guarantee concrete slab smooth at seaming position, so need cost more man-hour; When template is made moist warpage can take place, cause seam crossing the discrepancy in elevation to occur, have a strong impact on the concrete plate surface quality; Can tightly combine after the concrete setting, and template dilatation chucking mutually with template, both time-consuming, effort when the dismounting template is easy to again the seam of template is damaged, template utilize number of times few again, increased construction cost.

In order to solve the long flitch keel phenomenon of a large amount of wastes in the construction, there is part construction department to introduce external steel wood combination type keel.Though it has solved the yielding problem of long flitch, no longer need planing, the problems that above-mentioned template exists are still unresolved, and the flitch of double-plate keel is also unresolved by the problem that nail damages.

Summary of the invention

Technical problem to be solved by this invention provides a kind of keel device of formboard fastening, it is simple in structure, can reduce labor strength, do not need the template piece during operation and add nail, the dismounting template is easy during concrete setting, do not damage template, can increase work efficiency greatly and save a large amount of timber.

Solving the scheme that technical problem of the present invention adopts is: the keel of support shuttering are the section bar that has the slit that communicates up and down, the template press strip is pressed on the edge of adjacent forms, the template press strip face of exerting pressure is connected with and compresses the dismounting lacing wire and pass slit on the keel, compresses dismounting lacing wire end and is fastened on the keel.

The invention has the beneficial effects as follows: because keel adopt mach holotype material, therefore can guarantee very high glacing flatness, also needn't consume a large amount of flitches; The special structure and the template press strip of these keel match, template no longer needs piece and adds nail, improved efficiency of construction, template is not produced and damage, stripping needs only the drop-down dismounting lacing wire end that compresses, and has reduced labor strength, can not destroy the edge of template again, thereby can recycle template, save timber, reduce construction cost.Though remove the groove that the back concrete plate surface can stay the template press strip, mend flat grooves and be easy to.Compare with the job practices of routine, use this device that template is recycled more than 20 times, the operating efficiency of installing, dismantle template can improve more than 10 times.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of keel of the present invention;

Fig. 3 is the structural representation of template press strip of the present invention;

Fig. 4 adjusts the structural representation of timber bead for the present invention.

Each label is represented successively among the figure: template 1, template press strip 2, compress dismounting lacing wire 3, voussoir 4, keel 5, cushion block 6, slit 7, adjust timber bead 8.

The specific embodiment

Referring to Fig. 2, the keel 5 that present embodiment adopts are two bottom surface opposed U-shaped section bars, have inserted cushion block 6 between the bottom surface is relative, two U-lags can be coupled together to form the slit 7 that communicates up and down simultaneously again.See Fig. 1, the edge of template 1 is laid along the slit 7 of keel 5, template press strip 2 is pressed on the edge of two adjacent templates 1, connecting at the face of exerting pressure of template press strip 2 and to compress dismounting lacing wire 3, slit 7 from keel 5 passes, and the shape (see figure 3) that compresses dismounting lacing wire 3 is a U-shaped, and the voussoir 4 on band inclined-plane is after compress dismounting lacing wire 3 ends and fill in, just can be fastened on keel 5 lower ends very easily, template 1 is pressed on the keel 5 tightly.After concrete plate surface solidifies, as long as oppositely knock the impaction state that voussoir 4 just can be removed keel 5 and template 1, remove keel 5 after, the drop-down annular end of dismantling lacing wire 3 that compresses, can make template 1 and concrete demoulding easily, the groove that template press strip 2 stays on concrete plate surface is mended flat with concrete.Referring to Fig. 4, construction module and the inconsistent situation of member modulus usually appear in building operations, at this moment template press strip 2 can not cover the slit at template 1 edge fully, can adopt cross sectional shape and template press strip 2 identical adjustment timber beads 8 to be pressed in the vacant position that the template press strip is reserved; When template 1 also can not replace template press strips 2 with adjusting timber bead 8 during buckling deformation fully yet.

Claims

1. the device of a formboard fastening, it is characterized in that: the keel of support shuttering are the section bar that has the slit that communicates up and down, the template press strip is pressed on the edge of adjacent forms, the template press strip face of exerting pressure is connected with and compresses the dismounting lacing wire and pass slit on the keel, compresses dismounting lacing wire end and is fastened on the keel.

2. by the device of the described formboard fastening of claim 1, it is characterized in that: keel structure is two relative U-shaped section bars of bottom surface, connects and the formation slit with cushion block between the U-shaped section bar.
