Description

Spiral combined type pillar

One technical field

What the present invention relates to is a kind of pillar structure of building field, particularly a kind of spiral combined type pillar based on block material and reinforcing bar.

Two background technologies

Pillar (comprising bridge pier) is one of chief component of industry and civilian construction, bridge, and its safety, economy, manufacturing convenience directly affect the performance indications of total.Existing pillar type (for example mainly comprises steel column, reinforced concrete post, steel core concrete column; " square, rectangle that reinforcing bar is put more energy into or polygon steel pipe concrete column "; The patent No. 200610151197.4), combination steel concrete column (for example, " steel of combination and concrete column and construction method thereof ", the patent No. 98805134.6), composite wood stock column are (for example; " fiberglass cloth coating PVC pipe concrete pile ", the patent No. 200720060234.0; " high density polypropylene pipe concrete pole ", the patent No. 200710027719.4) etc.These pillar structure can both meet the demands aspect strength and stiffness, but will consume more steel or concrete, and production steel and cement need consume a lot of natural resources and the energy.Can improve this problem though introduce the pillar of materials such as glass fiber, polyvinyl, be limited to the problem of aspects such as cost, be difficult to popularized.Therefore, under the current overall background of advocating sustainable development, see, be necessary to seek more novel pillar material and form of structure.

Three summary of the invention

The objective of the invention is to overcome deficiency of the prior art, a kind of energy-conserving and environment-protective, the rational spiral combined type of stressed mechanism pillar structure are provided.

Structure of the present invention comprises building block, embedded reinforcing bar, overlap joint reinforcing bar, cementing agent.An embedded reinforcing bar is arranged in each building block; Four building blocks with different embedded reinforcing bar height are arranged a basic layer that constitutes pillar at same horizontal plane by reinforcing bar height order from low to high by four limits of rectangle; Each basic layer is at the whole pillar of formation that vertically gathers into folds, and the interconnect function through the overlap joint reinforcing bar makes the embedded reinforcing bar of each section become as a whole with each building block at last.On the interface of each layer building block, smear cementing agent.Described building block, plane cross section are shaped as T shape or rectangle, and material can adopt ordinary concrete, but preferentially select energy saving and environment friendly building materials for use, like gypsum, fly ash concrete etc.

Described embedded reinforcing bar, along continuous straight runs is arranged, is run through the building block at place, and respectively stretch out a bit of in two ends of building block.

Described basic layer comprises four building blocks with different embedded reinforcing bar height, and by reinforcing bar height order from low to high these four building blocks is carried out arranging clockwise or counterclockwise.

Described connection is meant four bights at pillar, welds the embedded reinforcing bar that connects in each staggered floor and the adjacent building block through the two ends of overlap joint reinforcing bar, and rule is to make each the embedded reinforcing bar after the connection become the integral body on the screw.

When carrying out the design of concrete structure; Position that can be different to pillar; Select the building block in varying strength or cross section for use according to stressing conditions: stressed big like the bottom of pillar; Can select the building block bigger than top block strength, perhaps the square-section is used in the top building block, and the bottom building block is with the bigger T type cross section of area.If pillar is bigger in the suffered power difference of two orthogonal directions of level, can adopt mixed type building block collocation, a direction adopts two square-section building blocks, and another direction adopts two T type cross section building blocks.

In addition; If the single building block of selecting for use is longer at vertical direction; Vertically can arrange a plurality of equally spaced embedded reinforcing bars, weld and connect each staggered floor and adjacent embedded reinforcing bar through the two ends of overlap joint reinforcing bar then, make each the embedded reinforcing bar after the connection become the integral body on the screw.On the interface of each layer building block, smear cementing agent equally.

This structural steel amount is little, the main material energy-conserving and environment-protective of preferentially selecting for use, and be the open-core type structure, reasonable stress.Under stressed very big, ultimate limit state that some building block is damaged by pressure, because each reinforcing bar has connected into a helical structure, the globality of pillar can also keep, and therefore has good ductility, can protect safety of life and property effectively.Even select for use common concrete to do block material, compare the existing concrete pillar and also have advantages such as less, easy to process with material, that shaping is fast.

In addition, but the present invention also has advantages such as batch production production, the duration is short, integrated cost is low, and adaptable across all kinds of building structure and bridge, technical meaning and social benefit are obvious.

Five specific embodiment

Elaborate in the face of embodiments of the invention down: present embodiment provided detailed embodiment and process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.

At first select suitable building block 1 size and material, be divided into four types in each building block 1 inner relative altitude difference, be designated as A, B, C, D (by ordering highly from low to high) according to embedded reinforcing bar 2 according to the force-bearing situation of pillar.

Per four building blocks 1 are arranged a basic layer that constitutes pillar on four limits that same horizontal plane is pressed rectangle; These four respectively corresponding four types of building blocks 1; And the order of pressing A, B, C, D is arranged clockwise or counterclockwise; Then each basic layer is constituted whole pillar vertically gathering into folds, on the building block interface of each layer, smear cementing agent.

Last in four bights of whole pillar, weld the embedded reinforcing bar 2 that connects in each staggered floor and the adjacent building block 1 through the two ends of overlap joint reinforcing bar 3, rule is to make each the embedded reinforcing bar 2 after whole pillar connects become the integral body on the screw.

The sectional schematic diagram of the pillar that employing T type cross section building block 1 constitutes is as shown in Figure 1.For receiving the less pillar top building block 1 of a power, for saving material, can select rectangle building block 1 for use, sectional schematic diagram is as shown in Figure 3.This part building block 1 is consistent with the outside dimension of bottom building block 1, and just inside has been used material less.In addition, if two stressed difference of mutually perpendicular direction of pillar are bigger, also can adopt the mix and match of T type cross section and square-section building block 1, sectional schematic diagram is as shown in Figure 4.

If the single building block 1 of selecting for use is longer at vertical direction; Vertically can arrange a plurality of equally spaced embedded reinforcing bars 2; Weld through the two ends of overlap joint reinforcing bar 3 then and connect each staggered floor and adjacent embedded reinforcing bar 2; Make each the embedded reinforcing bar 2 after the connection become the integral body on the screw, the elevational schematic view of this moment is as shown in Figure 5.
