Abstract

The invention relates to a construction process for permanent template members used for construction of columns, and aims to provide a construction process for precast porous columns so as to solve the problems of long construction cycle of buildings and material consumption caused by template building in the prior art. The construction process for the precast porous columns comprises the following steps of: manufacturing the precast porous columns in batches in a manufacturing place; transporting the precast porous columns to a construction site; performing positioning erection by matching cavities of the precast porous columns with longitudinal bars; and performing concrete spouting construction in a cylindrical formwork shell. Construction members are light and thin semi-finished column shells which can be produced in large scale by a factory, are transported to the construction site for assembly and then are poured with concrete so as to form combined type structural members. The construction speed is high, and a site supporting template is not needed.

Description

Prefabricated porous post construction technology

Technical field

The present invention relates to a kind of construction technology of permanent type modular shuttering element of the construction that is used for post.

Background technology

The house that conventional construction method is built; Owing to receive the influence of operator's technical level, construction technology etc.; Be difficult to satisfy the requirement of people, and in whole building course, traditional job practices is also very surprising in the waste of aspects such as material, the energy, labour to quality.

The building method of traditional post is: the shelf of putting up location usefulness earlier; The location places reinforcing bar, uses sheet material to be barricaded as then and carries out the concrete cast after the template, treats after the concrete moulding stripping again; Such job practices has a very big drawback; Be exactly in the front and back of cast work, need to consume a lot of manpower and materials and handle post template all around, and when carrying out the construction of heavy in section post; Often need once the above construction that repeats to build cylinder, just prolonged the construction period in house to a certain extent.

Summary of the invention

The invention is intended to provide a kind of prefabricated porous post construction technology,, template long with the construction period that solves house in the prior art built the problem that causes the consumption of materials.

The object of the invention can reach through following measure: the prefabricated porous post construction technology in this programme is characterized in that may further comprise the steps:

A) make prefabricated porous post in batches at manufacturing field;

Said prefabricated porous post comprises the formwork and the stirrup that is fixed in the formwork of tubular, and said stirrup includes the housing muscle, is provided with interior muscle more than in the housing muscle; The two ends of muscle are connected on the housing muscle in said; The housing muscle is located in the formwork, is fixed with vertical muscle on the housing muscle, is provided with the partition more than in the said formwork; Said partition is with being divided into more than one cavity in the formwork, the upper and lower surfaces of said formwork is provided with the connection draw-in groove that matches;

B) prefabricated porous post is transported to the job site;

C) be cylinder with prefabricated post construction member location and installation;

D) erection column lengthways main steel bar in formwork;

E) in formwork, carry out the concrete spouting construction.

The technique scheme difference with the prior art is: construction member is frivolous semiproduct post housing; Can be by plant layout production; Transport to on-site consolidation concreting more later on, form the fabricated structure member, speed of application soon, does not need on-the-spot supporting template.Said stirrup can guarantee the structural stability of prefabricated porous post in transportation and concreting process, and after installation and construction finished in building, described stirrup was still brought into play its due effect.

Further: in said step c: described cylinder comprises first section prefabricated porous post and second section prefabricated porous post, uses lifting appliance that second section prefabricated porous post is promoted to first section prefabricated porous post top installation in position.

Further: in said step e,, in the cavity that keeps, carry out the layout construction of spool then according to concreting and reserve part cavity in the cavity of designing requirement in formwork.

Its characteristics are: the reserve part cavity does not carry out concreting, and the cavity that can make full use of not perfusion carries out pipe line arrangement, has practiced thrift material and has made full use of the space.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:

Fig. 1 is the generalized section of the embodiment of the invention;

Fig. 2 is for looking sketch map on the embodiment of the invention;

Fig. 3 is that the A-A of Fig. 2 is to cross-sectional schematic;

Fig. 4 is the sketch map of many limbs net sheet stirrup in the embodiment of the invention.

The specific embodiment

Known concrete structure and characteristic are no longer set forth at this in the following proposal.Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4: prefabricated porous post comprises the formwork 1 of square tubular and many limbs net sheet stirrup 2 of Qi Nei.Formwork 1 is the low heat conduction strong concrete moulding in factory of lightweight, also is provided with the partition of " well " font in the square formwork, intermeshes between four partitions, and the top layer also is provided with the clear-water concrete layer, and the corner of formwork 1 short transverse is a post fillet 14.

The upper and lower surfaces of formwork 1 is provided with the connection draw-in groove that matches; Said connection draw-in groove comprise connect draw-in groove 11 with under be connected draw-in groove 12; Last connection draw-in groove 11 with under be connected draw-in groove 12 and can cooperate and be mounted in together, the edge in the formwork outside of said connection draw-in groove is equipped with chamfering 13.

Formwork 1 inside when moulding has just embedded the sheet of limb net more than three layers stirrup 2 (as shown in Figure 3), and the housing of many limbs net sheet stirrup 2 has been imbedded in the formwork 1 fully, and the plane at many limbs net sheet stirrup 2 places is perpendicular to the short transverse of formwork 1.Housing muscle 21 around many limbs net sheet stirrup 2 comprises and horizontal vertical staggered interior muscle 22.Housing muscle 21 is the ring muscle with interior muscle 22 and constitutes, and each ring muscle all is to be welded from beginning to end to bend by a reinforcing bar to form, and said ring muscle is surrounded by the circular arc at parallel two long limits and two ends, and the solder joint on the ring muscle is positioned at the middle part on a length limit.

Housing muscle 21 is welded from beginning to end by four ring muscle and is square; The with one heart superimposed constrained port 231 that is a sealing that encloses of the circular arc of adjacent ring muscle end wherein; The circular arc of interior muscle 22 ends and housing muscle enclose the constrained port 232 that has been sealing equally, and staggered interior muscle 22 also encloses and is a plurality of constrained ports 233, and weld at contacted position between reinforcing bar; In the manufacture process of formwork 1; Muscle forms steel and concrete structure in just being embedded in and having cut off in described, is cut off in the formwork 1 to be divided into nine relatively independent square cavity, can independently carry out concrete pouring to each cavity.

In concrete construction process, comprise the steps:
