Abstract

The present invention relates to a template support and construction method for construction engineering. A rectangle steel pipe with a cold bending thin wall is used as a template support of a concrete column, one bar-shaped hole is milled at one end of the support, and the end is used as a clamping end; a plurality of round holes are drilled according to the normally used dimensions of columnar molds at the other end which is used as a fixing end. A straight male pin, wedge-shaped pins and wedge supports are used as fasteners; at the time of mold supporting, the straight male pin is connected with the fixing end which is supported by the crossed columnar moulds in the mode of penetration according to the dimensions of the columnar molds, and two pairs of wedge supports and the wedge-shaped pins respectively penetrate the clamping end supported by the large surfaces and the small surfaces of the columnar molds. The top of each wedge-shaped pin is knocked symmetrically until the support is wedged tightly, and the bottom of each wedge-shaped pin is knocked at the time of demoulding so that each wedge-shaped pin is loosened and withdrawn. The template support and construction method has the advantages of simple structure, component saving, simple and convenient operation, reliable fastening effect, long service life of support, reduced construction cost and enhanced construction quality and operation efficiency.

Description

A kind of building engineering shuttering supports and job practices

Affiliated technical field

The present invention relates to a kind of building engineering shuttering supports and job practices.

Background technology

Flitch commonly used, two steel pipe or angle steel are done the template support of reinforced concrete post in the construction work at present, and the fastening method of support is:

Flitch supports: with 8 ^#It is tight that iron wire (sub-thread or bifilar) supports strand with two relative lumps of wood.

Two steel pipes support: with split bolt two pairs of relative steel pipes are supported tension with the butterfly fastener.

Angle steel supports: support at the fixing angle steel that intersects in the typing hole of two crossing angle steel with selling nail or bolt directly to households.

There are the following problems for these methods commonly used:

1. flitch needs the tight iron wire of ad hoc strand, the iron wire large usage quantity, and be disposable consumption, cost is too high, and is not suitable for big section post.

2. two steel pipes need ad hoc split bolt.Though split bolt is reusable, its application life is short, and the number of turnover is less; And bolt length fixes, and is difficult to extensively adapt to the variation of post cross dimensions, thereby needs to be equipped with plurality of specifications; The screw thread of bolt is safeguarded has also increased the cost expenditure.

3. though angle steel has been saved ad hoc strain component, but its pin and bolt only can be at typing hole site fixed support nodes, thereby can not play tension and support the effect that clamps template, it is tight to cannot say for sure to demonstrate,prove the template angle seam, if adopt the method for folder timber wedge then to increase workload and material consumption; Angle steel supports and also is not suitable for big section post.

Summary of the invention

For the template that overcomes reinforced concrete post commonly used support and job practices in the drawback aspect operating efficiency and the construction cost, the invention provides a kind of new supporting tool and job practices, use this tool and method, can improve reinforced concrete post form erecting operation efficient and quality, directly reduce material cost aspect simplification supporting member and the raising support turnover rate.

The technical scheme that technical solution problem of the present invention is adopted is:

Using the cold bending thin wall rectangular steel pipe to make the post mould supports.Respectively establish 2, minor face on the long limit of column section and respectively establish 1 support, form four limit support systems by 6 supports, two diagonal angle intersection points that support on four limits are pinching end, two other diagonal angle intersection point is a fixed end, use to sell directly to households and follow closely the fixedly crossing fixed end that supports in two sides, thereby use wedge pin and wheel chock intersect support respectively on the two sides the crossing support of pinching end wedging to clamp template.

As pinching end, bore circular hole as fixed end at the other end at an end mill one bar hole that supports, fixed end can be provided with several circular holes by post mould Commonly Used Size; Use to sell directly to households and follow closely the fixedly crossing fixed end that supports in two sides,, thereby use wedge pin and wheel chock intersect support respectively on the two sides the crossing support of pinching end wedging to clamp template according to inclined plane principle.

Mutually as intersecting the strain component that supports, use the template of wedge pin and the fastening concrete column of wheel chock or other pillar member to support with template supporting member itself, contact with two parallel inclined-planes between wedge pin and the wheel chock.

The invention has the beneficial effects as follows:

1. that utilizes crossing support itself makes strain component mutually, according to inclined plane principle, clamps and fixed support with wedge pin, has saved the strain component of establishing in addition.And support and pin member simple structure, maintenance expense is low, and the proportion of goods damageds are low, the turnover rate height, long service life reduces construction cost.

2. simple to operate, improve operating efficiency; Fastening reliable for effect, improve construction quality.

3. when being used for big section post, quality and economic effect are more remarkable.

Description of drawings

Below in conjunction with accompanying drawing invention is described further:

Fig. 1 is post mould supporting plane figure, and 1-1,2-2 are respectively the sectional drawings of Fig. 1.

Fig. 2 is supporting pin hole site figure.

Fig. 3 is pin member figure.

1. in Fig. 1 and the sectional drawing thereof is big support of post mould, 2. is that post mould facet supports, and 3. is column template, 4. is wheel chock, 5. is wedge pin, 6. is to sell nail directly to households.

The specific embodiment

During formwork, in Fig. 1, select the fixed end circular hole by post mould size, follow closely 6. big support of cross-under post mould with 1 direct selling and 1. support 2. fixed end with facet, again 5. 4. 2 pairs of wheel chocks penetrated big support of post mould respectively with wedge pin and 1. support 2. pinching end with facet, two pinching ends are symmetrical simultaneously at the diagonal angle knocks corresponding wedge pin top 5., supports until wedging.

During form removal, reverse operating, the wedge pin bottom 5. of knocking two pinching ends is moved back its pine, pulls down support.

Claims

1. a building engineering shuttering supports job practices, the template of support and fastening concrete component, it is characterized in that: respectively establish 2, minor face on the long limit of column section and respectively establish 1 support, form four limit support systems by 6 supports, two diagonal angle intersection points that support on four limits are pinching end, two other diagonal angle intersection point is a fixed end, uses to sell directly to households and follows closely the fixedly crossing fixed end that supports in two sides, thereby use wedge pin and wheel chock intersect support respectively on the two sides the crossing support of pinching end wedging to clamp template.

2. building engineering shuttering according to claim 1 supports job practices, it is characterized in that: mutual to intersecting the strain component that supports with template supporting member itself, use the template of wedge pin and the fastening concrete column of wheel chock or other pillar member to support, contact with two parallel inclined-planes between wedge pin and the wheel chock.
