Abstract

The utility model relates to the field of concrete pouring, in particular to a construction device for special-shape structure large-volume concrete pouring. The construction device solves the problems that the conventional special-shape structure concrete is difficult to pour and the vibrating bar is uncompleted in vibration, and comprises UPVC guide pipes, wherein the UPVC guide pipes are distributed at intervals in a special-shape structure and are fixed with structural reinforcing steel bars; lifting holes are symmetrically formed on the walls of the UPVC guide pipes at intervals; and hoppers are arranged at the upper ports of the UPVC guide pipes. By the construction method for performing special-shape structure concrete pouring through using the construction device as the concrete guide pipes and the vibrating holes, the problems that the structure is high and has a special shape, the structure concrete pouring is difficult and the vibrating bar is uncompleted in vibration are solved, the flowability of the special-shape structure concrete is guaranteed, no separation occurs, and the construction device is simple and convenient in construction, low in manufacturing cost and short in work period and has popularization and application values in the large-volume concrete pouring process of the industrial building special-shape structure.

Description

Abnormally-structured prevention of mass concrete is built and is used construction equipment

Technical field

The utility model relates to the concreting field, is specially a kind of abnormally-structured prevention of mass concrete and builds and use construction equipment.

Background technology

Continuous development along with China's industrial construction; The construction of industrial premises progressively scale is maximized, and some large-scale industrial construction constructions exist abnormally-structured, like the kiln pier of cement plant; And construction does not allow to keep somewhere constuction joint, and the concrete volume is big and structure is special-shaped just brings very big difficulty to construction.Mass Concrete Construction itself just exists certain degree of difficulty as a special construction process of builing industry construction in the routine construction, because the free drop of concrete is bigger; Cause the segregation of concrete easily, there is concrete not in place, the vibrating spear problem not in place of vibrating that flows in the structure abnormal shape simultaneously at root, has brought difficulty to construction more; Carry out adopting when concrete is built the iron sheet conduit at present at abnormally-structured position; Need process at the construction field (site), and itself is heavier, it is not too convenient to move and promote.

Summary of the invention

The utility model is built difficulty, the vibrating spear problem not in place of vibrating in order to solve existing abnormally-structured concrete, provides a kind of abnormally-structured prevention of mass concrete to build and uses construction equipment.

The utility model is to adopt following technical scheme to realize: abnormally-structured prevention of mass concrete is built and is used construction equipment; Comprise be laid at interval abnormally-structured in and the UPVC conduit that is fixed together with structure reinforcing bars; The interval symmetry has and lifts the hole on the UPVC duct wall, and UPVC conduit port is provided with funnel.

Adopt the structure design of the utility model,, choose the UPVC pipe of different-diameter and height according to abnormally-structured height, width, special-shaped angle, the difference of reinforcement placement spacing; Carry out the laying in the conduit and the hole of vibrating according to the flowability of concrete and the scope of vibrating of vibrating spear; Utilize funnel to carry out building of concrete,, guarantee that concrete can be in the density of structural base simultaneously through the vibrating of vibrating spear; Hole does not appear, the mass defect of concretes such as voids and pits.The UPVC conduit is laid according to the flowability of concrete and the scope of vibrating of vibrating spear with the definite of hole number of vibrating, and wants the closeer position of choice structure reinforcement placement simultaneously, like sleeper etc., guarantees building and vibrating of structural base concrete.

Adopt the said construction equipment of the utility model to carry out the construction way that abnormally-structured concrete is built, efficiently solve the tall and big abnormal shape of structure, and construction does not allow to stay constuction joint as the concrete conduit and the hole of vibrating; The structure concrete is built difficulty, and the vibrating spear problem not in place of vibrating has guaranteed the flowability of abnormally-structured concrete; Do not produce segregation, and easy construction, cheap; Duration shortens, and building at the abnormally-structured prevention of mass concrete of industrial construction has excellent popularization use value in the process.

The specific embodiment

Abnormally-structured prevention of mass concrete is built and is used construction equipment; As shown in Figure 2; Comprise the UPVC conduit 2 that is laid at interval in abnormally-structured 1 and is fixed together with structure reinforcing bars, on the UPVC duct wall at interval symmetry have and lift hole 5, UPVC conduit 2 port are provided with funnel 3.

As shown in Figure 1, carry out simultaneously at abnormally-structured reinforcing bar binding, carry out the configuration of catheter length according to the height of structure; To guarantee during installation that the UPVC conduit can freedom twitch up and down, the about 200-300mm in distance structure bottom, the UPVC conduit is as the importing approach of concrete conduit and vibrating spear; Carry out the limit and build the concrete limit and rise and carry through lifting the hole, concrete is imported by eminence, and vibrating spear is imported; The quality of concrete is guaranteed, does not produce, guarantee that the concrete of structure root is built, vibrating puts in place from wash rice.

Construction sequence is following:

1, concrete kind: concrete adopts Commercial Concrete, requires the slump at 160 ± 20mm, and can guarantee continuous placing.According to on-site actual situations, to carry out the on-the-spot people's material machine that stirs simultaneously and prepare, the emergency measure when not going up in order to the Commercial Concrete supply guarantees the continuous placing of concrete really.

2, the making of UPVC conduit: according to structural requirement, the UPVC pipe of buying suitable diameter is 150mm like the reinforcing bar minimum spacing; So it is the pipe of 150mm that pvc pipe is selected diameter for use; Whenever on tube wall, scald the hole at a distance from 1～1.2m symmetry, when lifting, reinforcing bar is passed, as drawing a little and fixed point.Funnel then adopts the bamboo offset plate to make.

3, casting method: because of main body is abnormally-structured, and highly higher, for preventing laminated segregation,, build (as shown in Figure 1) in the method for conduit placement funnel suitable for reading so the concrete casting method adopts the UPVC conduit.

4, UPVC conduit arrangement requirement:, be fixed in the structure reinforcing bars simultaneously in the reinforcing bar binding process according to the suitable radical of agent structure configuration UPVC conduit.

5, concrete is built: before concrete is built, should be with clear water that flushing in the main column is moistening earlier, and guarantee can well flow after concrete gets into.

When concrete is built, should in agent structure, utilize funnel and UPVC conduit (pipe apart from architecture basics 4 end face 300mm, during pouring with watering with carrying) to carry out seat slurry earlier, it is 50～70mm that seat is starched thickness.The seat slurry back that finishes is carried out the concrete pouring at once, avoids intermittently causing bottom mortar flowability to diminish or loses flowability.Concrete is built pump line and will be moved around, and the special messenger operates pump line and conduit, build highly to surpass 300mm at every turn, and should be with building with vibrating.Will observe the distortion situation of template, support, reinforcing bar, built-in fitting, reserving hole when concrete is built at any time, when finding to change, during dislocation, stop immediately building, take measures, finishing is intact before the concrete of having built condenses.For preventing that concrete from building the too fast stressed excessive race mould that causes of form frame system that makes, the mould that rises, two piers are built simultaneously, hocket.
