Abstract

A construction method of building with longitudinal section topography incldues to make the design drawings of construction for each section between the two parallel flat surfaces on the building main body first, then to prefabricate each section and at last to lift each section and construct them on the finished foundation to form the complete building body by connecting, fittings and using adhesives. The present invention has the advantages of low cost, short period of construction and no requirement for the scaffold in the construction.

Description

Longitudinal cutting process for building construction

The present invention relates to a kind of construction techniques of multi-storey building.

Traditional building operations all is from ground, gradually from bottom to highrise building, the finishing of exterior wall in carrying out again after the whole building body completion, to scaffold erecting inevitably in the work progress, and needing bigger place deposit constructional materialss such as cement, brick and tile, the air and the noise pollution of construction site are serious, meet rainy day or the weather that blows hard is just muddy more can't bear, flying sands and howling wind, even cause the loss of constructional materialss such as cement.

The purpose of this invention is to provide a kind of new construction techniques, each prefabricated component with the simple and convenient prefabricated building of method, and then it is assembled up to finish whole building construction process, one can solve the pollution of environment and noise, two can significantly reduce the building time in the construction site, reduce production costs.

For achieving the above object, the present invention adopts following technical scheme: longitudinal cutting process for building construction of the present invention comprises the steps: one, architectural design

Except that designing traditional building operations drawing, also will go out to form the construction drawing of each fragment of this building according to the shape of building and structure design, the fragment of described building is meant a part of body of wall and the ground between two parallel planes on the building main body; Two, building lot and prefabricated fragment

Job practices commonly used can be adopted in the basis of building, but outside the building prefabricated connector is wanted in the junction of wall and ground; The template that will be used for the production building fragment keeps flat on the ground, produces each fragment that needs according to the production method of common architectural prefab; Three, assembling combination

The fragment of producing good building is sling, be arranged in order the correspondence position that is installed in ground, and each fragment be connected in one by the connector that presets.

In the production building fragment, can carry out exterior wall finishing in it; At first interior and exterior decoration material is fixed on the inwall of template, and then fluid concrete, pull down template after the concrete drying again.

In the assembling combination stage, at first on the mating face of each fragment, smear bonding agent, and then connect by connector.

In the process of prefabricated fragment, to on the mating face of adjacent segment, be provided with concavo-convex join and parts, and with the contact surface of ground on junction plate is set, have bolt hole on the junction plate, be fixed on the ground by the bolt hole on the junction plate in the assembling combination stage.

Adopt above-mentioned building method to carry out the building operations of multi-storey building, the production of each building fragment can be carried out in the factory of specialty, can reduce the environment pollution to the construction site; The construction of carrying out in the construction site only is to combine producing good fragment lifting, and short construction period does not need to scaffold erecting, and can save a part of operating expenses.

Further specify the present invention below in conjunction with drawings and Examples.

Fig. 1 is the schematic diagram of dividing method of the fragment of one embodiment of the present of invention;

Fig. 2 is the structural representation of a fragment in the building of Fig. 1;

Fig. 3 be with Fig. 1 in the schematic diagram of the adjacent fragment of fragment.

Fig. 4 is the schematic diagram of dividing method of the fragment of an alternative embodiment of the invention.

As shown in Figure 1, building with a building five floors as shown in Figure 1 is an example, in the drawing of design building thing, just the drawing of each fragment 1 of this building is designed, the fragment 1 of described building is meant a part of body of wall 2 between two parallel planes and ground 3 on the building main body, suppose promptly that also having some parallel planes that this building longitudinally cutting is become the multistage width is the fragment (as shown in phantom in Figure 1) of 1-1.5 rice, the structure chart and the working drawing of each fragment 1 are designed, and design the pipeline and the connector that need be arranged in each fragment 1 simultaneously.The roof can be used as an independent special fragment and makes, and also it can be divided on each fragment, is designed to one with body of wall and ground.Each fragment 1 should meet following condition as far as possible: doorframe and window frame are kept perfectly, for the door and window part of large span, in the time of must being divided into a plurality of fragment, need the relevant position to increase interim bracing piece.2) width can not be too big, was not advisable not need scaffold to construct after falling.3) as far as possible that staircase etc. is little space is as a complete fragment, to reduce the difficulty of design, construction.

After the drawing design of each fragment is finished, can in factory, finish the prefabricated of each fragment according to the method for common production architectural prefab, in order to make the connection of each fragment convenient and tightr in the assembling combination stage, as Fig. 2, shown in Figure 3, the parts 5 of concavo-convex cooperation can be set on the mating face of adjacent segment, and be provided with the junction plate 4 of bolt hole in the bottom of each fragment.Be with the difference of producing the common building prefabricated component, 1) comprises the various pipelines and the connector that need be embedded in the building masonry wall in the fragment of the present invention, as above the protecting pipe of sewer pipe, power line and be used for connector that is connected with other fragment etc.2) can when making each fragment, finish the finishing of exterior wall in it, for example: the exterior wall at building pastes mosaic if desired, can stick mosaic in the corresponding position of template inwall of production fragment, the template of dismantling behind the casting complete, mosaic just has been attached on the outer wall of fragment.3) joint of each fragment and other fragments should be smooth as far as possible, connects each other and bonding reliability to improve.

Carry out the construction of ground according to the method for routine, and on ground, preset a metal end frame, have bolt hole on this metal end frame, make the bolt hole on the junction plate 4 of bolt hole and each fragment 1 bottom on the metal end frame corresponding.

Each fragment sling successively to be placed on the correspondence position of ground, at first is fixed together with the junction plate 4 of bolt with metal end frame and fragment 1 bottom, and then by pre-connector in each fragment 1 adjacent fragment 1 is linked together.Like this, main building just has been connected in one, if interior and exterior decoration material just is attached on each fragment 1 when the production fragment, this moment, the method for processing can have multiple as long as the slit of two fragments, 1 junction is handled well just passable.For example, paste for exterior wall that the processing of mosaic is can be at the place, slit of exterior wall staggered sticks mosaic and promptly can cover the slit, the processing of interior wall tile fixing also can be adopted this method, at this moment the main body construction of building is finished, the work such as connector, interior exterior wall skin of handling do not need to scaffold erecting, greatly reduce the cost of construction, improved safety of construction.

Certainly, the dividing method of each fragment 1 of building can have multiple, is another kind of dividing method as shown in Figure 4.

In order further to improve the soundness of constructure body structure, can also adopt two kinds of following methods:

Bonding agent is smeared in joint portion in each fragment 1, makes the building each several part in conjunction with tightr, can also improve its water resistance simultaneously.These be used between the concrete and concrete and steel between bonding agent have multiple known technology available, be that 96119044 " sticking anchor formula steel clad reinforcement adhesives and reinforce worker's method " and application number are 98103016 " concrete interface treating agent and preparation method " as application number.

The method that increases binding steel at the suitable position of building can improve the soundness that connects between each fragment, preferably the place near the room item increases binding steel on building top, with expansion bolt steel band is fixed on the exterior wall of building, by welding or bolted method steel band is connected into a stirrup that is centered around on the building again.Concrete job practices also has many known technologies, is 99105829 " method of reinforcing concrete buildings " as application number.

Certainly, the method for building strengthening also has many known technologies, describes in detail no longer one by one at this.
