Abstract

The invention relates to a construction method for cast-in-situs concrete construction with no hole in building construction technique sphere, accordingly installs a support between forming boards and a vertical hard-drawn wire via the boards, and then tightening fixes the boards via fixing the hard-drawn wire from one end to another end, at last cuts the hard-drawn wire at the boards when removing the boards thereby completing the method. The method has advantages that the concrete has no hole thereby improving the integrality of buildings and the aseismic behavior, and can be extensive used in multilayer and small high-level and high-level buildings, therefore a revolution is brought to the cast-in-situs concrete construction with further technology value and social benefit. To the economy, the embedding of the hard-drawn wire can save material cost of PVC wall pipes or bamboo tubes or the like and decrease the cost greatly, while saves plugging of holes and labor cost and improves the construction efficiency and the construction quality via avoiding the leakage water question of plugging holes.

Description

Cast-in-situ concrete structure non-hole construction method

Technical field

The present invention relates to technical field of building construction, relate in particular to job practices with the cast-in-place moulding shear column of template, beam, wall.

Background technology

At present, concrete cast-in-situ wall, post, beam are to utilize the mode of through-wall bolt formboard fastening to construct, as shown in Figure 1, during construction, earlier pre-buried wall pipe 5 between the template 4, through-wall bolt 6 is passed the template of both sides and middle wall pipe, and square stock 3 or square steel on the pad of template both sides then compress template from both sides the job practices of making support of reinforced bar support 8 again with 3 shape cards 1 and steel pipe 2 and clamp nut 7.The shortcoming of this mode is: behind the stripping, because the extraction of through-wall bolt, can form the numerous hole that connects the concrete section on the concrete face, according to the requirement that through-wall bolt distributes, general every square metre can form 3-5 hole, and the problem that these holes bring is: need shutoff after the construction, not only can increase engineering quantity, and shutoff sternly can not cause seepage problem (as the concrete exterior wall seepage problem), forms common fault, influences workmanship.Crucial problem is the hole owing to the One's name is legion that forms on the concrete section, can influence the structural performance and the shock resistance of whole building, causes some accident potential.

Summary of the invention

At foregoing, the object of the present invention is to provide non-hole construction method in a kind of cast-in-situ concrete structure, with structural performance and the anti-seismic performance of improving the Cast-in-place concrete body.

For achieving the above object, technical program of the present invention lies in having adopted a kind of cast-in-situ concrete structure non-hole construction method, this method is that support member is set between forming panel, on template, wear vertical cold drawn wire or iron wire, then by fixedly the fastening mode of other end stretch-draw is fastening with template from an end with cold drawn wire or iron wire, when stripping, can finishes the concrete body structure surface and do not have hole and construct as long as cold drawn wire or iron wire cut off from template.

Described concrete structure cold drawn wire or iron wire are cold drawn wire or the iron wire of diameter at 4mm-6mm.

Described template is with the fixing two ends of anchor clamp.

Described cold drawn wire or iron wire carry out the reinforcing operation with jack.

Described reinforcing square stock is with channel-section steel or angle steel.

As can be seen, the present invention's employing replaces by through-wall bolt the fastening mode of cold drawn wire stretch-draw tightens fixing mode, has saved PVC wall pipe or thick bamboo tube, bolt draw bar, and instruments such as 3 shape cards, during stripping, the cold drawn wire of wiping out template face root gets final product.First advantage of this mode promptly is that the concrete body does not have hole, the building body does not have the hole globality to be strengthened, improved anti-seismic performance, anti-permeability performance, be suitable for applying of multilayer, little high level and the underground ground of highrise building, brought a revolution for undoubtedly the construction of Cast-in-place concrete beam column wall, far-reaching technological value and social benefit are arranged.From economy, imbed cold drawn wire, saved PVC wall pipe or thick bamboo tube and other material, also save the shutoff of hole, saved cost of labor, improved efficiency of construction, also avoid simultaneously the leakage problem that sternly do not bring because of hole and holes blocking, improved construction quality.

Fig. 2 is the fixed form schematic diagram of the template of job practices of the present invention;

Fig. 3 is applied to the schematic diagram of under ground portion structure for job practices of the present invention.

The specific embodiment

As shown in Figure 2, Cast-in-place concrete post of the present invention, beam, wall non-hole construction method, this method is that support member 9 is set between forming panel 4, on template 4, wear vertical cold drawn wire 10, then by with cold drawn wire 10 from an end fixedly the fastening mode of the other end stretch-draw template 4 is fixed, the casting complete concrete strength meets the requirements before the stripping, cuts off and can finish from template face position with cold drawn wire.Cold drawn wire 10 is the cold drawn wire of diameter at 4mm-6mm.Among Fig. 2, an end of cold drawn wire 10 is fixing with anchor clamp 11, and the other end is also fastening with anchor clamp 11 with the cold drawn wire tensioning with jack or other tightener.Among Fig. 2, the both sides of template 4 are lined with square stock 12, and square stock is pressed with angle steel or channel-section steel class pressing piece 13 outward, and the pressure of opening of cold drawn wire 10 is given template 4 by anchor clamp 11, angle steel or channel-section steel class pressing piece 13, square stock 12 conduction.

As shown in Figure 3, when under ground portion was constructed, be with the difference of overground part shown in Figure 2: the center fixed at cold drawn wire or iron wire 10 had sealing sheet 14.

In some construction occasion, the whole large steel moulding plate of template for being made of plate face and sheet frame when using this method, can save square stock, and a pressure of cold drawn wire 10 directly conducts by anchor clamp 11, angle steel or channel-section steel class pressing piece 13 gives template 4.

It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
