Description
Technical field
The utility model relates to a kind of concrete column, is specifically related to a kind of steel pipe and exempts from the vibration concrete post.
Background technology
Concrete column is the most basic supporting member in the various engineering structuress such as house, bridge, water conservancy project, is commonly used for the depression bar of pillar, bridge pier, foundation columns, pylon and the truss of superstructure.Concrete column need to vibrate in casting process, to guarantee pouring quality, wastes time and energy but vibrate, and the engineering time is long, and project benefit is low.
The utility model content
The purpose of this utility model is in order to solve existing concrete column in casting process, and vibrating wastes time and energy, and the engineering time is long, the problem that project benefit is low, and then provide a kind of steel pipe to exempt from the vibration concrete post.
the technical solution of the utility model is: a kind of steel pipe is exempted from the vibration concrete post and is comprised that cross section is the steel column of rectangle, described concrete column comprises that also cross section is circular steel column, funnel, dividing plate, hanger and Duo Gen reinforcing bar, dividing plate is provided with charging aperture, cross section is vertically set on ground for circular steel column, cross section is that the steel column of rectangle vertically is sleeved on cross section on circular steel column, and cross section is that center and the cross section of the steel column of rectangle is the dead in line of the steel column of circle, dividing plate is arranged on the upper end that cross section is the steel column of rectangle, funnel is the funnel with guide pipe, funnel is fixedly installed on charging aperture on dividing plate by many reinforcing bars, and the guide pipe of funnel lower end is connected with the upper end that cross section is the steel column of circle, hanger is arranged on the top of funnel.
The utility model compared with prior art has following effect:
1. funnel of the present utility model is the funnel with guide pipe, effectively avoids gas under dividing plate fully to overflow and forms the cavity.
2. the utility model directly gets final product concreting by funnel in steel rectangle column and circular steel column, the high self-compacting concrete requirement concrete of exempting to shake of throwing itself has the works fine performance of upper flow regime, protect plasticity, education resistance, slow setting and microdilatancy, take the high position of " controlled orderly " to leave mode when building, need not to vibrate, reach the effect of concrete self-compaction.
3. steel core concrete column of the present utility model is compared with common steel column, and component are few, weld seam is few, particularly because steel pipe is relatively thin, has alleviated workload and the welding difficulty of Site Welding; Compare with reinforced concrete post, saved the time of reinforcing bar binding, formwork form removal and concrete curing, shortened the construction period.
4. the utility model as the steel core concrete column of compressed member,, improves concrete compressive strength, and becomes plastic material by fragile material concrete lock ring effect due to steel pipe, and key property has played the variation of matter.Due to fill concrete in steel pipe column, improved the local stability of thin-wall steel tube simultaneously, the yield strength of steel pipe can be taken full advantage of.Therefore in steel core concrete column, bi-material can make up weakness separately mutually, brings out one's strong points, thereby has greatly improved bearing capacity.
5., there are not the phenomenons such as the quick-fried mould of spillage in steel pipe column encased steel plate good seal performance of the present utility model during concreting; To exempt from vibration concrete be the self-compacting concrete that need not to vibrate because height is thrown in addition, can not produce the noise pollution environment that vibrates and send because of vibrating head.
Description of drawings
Fig. 1 is front view of the present utility model; Fig. 2 is the top view of Fig. 1.
The specific embodiment
the specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, a kind of steel pipe of present embodiment is exempted from the vibration concrete post and is comprised that cross section is the steel column 1 of rectangle, described concrete column comprises that also cross section is circular steel column 2, funnel 3, dividing plate 5, hanger 6 and Duo Gen reinforcing bar 4, dividing plate 5 is provided with charging aperture 7, cross section is vertically set on ground for circular steel column 2, cross section is that the steel column 1 of rectangle vertically is sleeved on cross section on circular steel column 2, and cross section is that center and the cross section of the steel column 1 of rectangle is the dead in line of the steel column 2 of circle, dividing plate 5 is arranged on the upper end that cross section is the steel column 1 of rectangle, funnel 3 is the funnel with guide pipe, funnel 3 is fixedly installed on charging aperture 7 on dividing plate 5 by many reinforcing bars 4, and the guide pipe of funnel 3 lower ends is connected with the upper end that cross section is the steel column 2 of circle, hanger 6 is arranged on the top of funnel 3.
The specific embodiment two: in conjunction with Fig. 1 and Fig. 2, present embodiment is described, the diameter of the reinforcing bar 4 of present embodiment is 25mm.So arrange, effectively accept funnel 3 and weight of cement.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: in conjunction with Fig. 1 and Fig. 2, present embodiment is described, the quantity of the reinforcing bar 4 of present embodiment is 2-4.Construction safety so is set.Other composition and annexation are identical with the specific embodiment one or two.
The utility model is to use like this,
1, namely add a cover cover sheet at the steel rectangle column column cap before the steel column hoisted in position, fall into rainwater-proof, oil, foreign matter.The interline link of going forward side by side is checked and accepted, and guarantees that steel column position error and welding quality satisfy code requirement.The inspection concrete placing installation is intact, installs firmly, organizes concrete to march into the arena.
2, erection construction operating platform before concreting, perform and face the limit security protection.
3, after self-compacting concrete was shown up, the reply concrete slump divergence of per car and T500 performance detected totally.
4, the self-compacting concrete field sampling is made test block, and any vibrating do not done in test block; Divide two layers and fill with concrete column; First floor is built cross section and is circular steel column 2, has built cross section and has taken off dividing plate 5 and funnel 3 after for circular steel column 2, then built the steel column 2 of circle of the second layer and the chamber between steel column 1 that cross section is rectangle.The surface troweling, press polish after final set.
5, molding temperature should be controlled at 10～25 ℃ of scopes, according to the difference of seasonal temperature, adjusts the concrete casting time.
6, because height is thrown the characteristics such as self-compacting concrete intensity is high, cohesiveness is large, pumping resistance is large, easy plugging when building, so in casting process, the pump line elbow will reduce as far as possible, prevents that pump line from blocking, the continuity that should keep solidifying soil to build.When building as interruption, must not surpass the concrete initial setting time break time of building.Rectangle steel tubing string concreting face should be below column joint about 30cm place.
If 7, laitance is arranged before concrete initial set, need laitance is scooped out to clean out.
8, clear up constuction joint after concrete final set, eliminating impurities in post is clean, cover cover plate and prevent that foreign matter from entering.
9, last segmented column concrete casting is to capital, and the employing cement mortar is floating with concrete surface after final set three days, concrete shrinkage are completed substantially.Complete building of concrete column.
