Description

Early-dismantling supporting device for building engineering

Technical Field

The utility model belongs to the technical field of building engineering and specifically relates to a strutting arrangement is early torn open to building engineering is related to.

Background

The traditional building construction mode has great influence on the environment and great resource consumption. In order to respond to the green construction call of the construction department, the repeated utilization of more times is realized as much as possible in the actual product use. The early-dismantling formwork system is a supporting system comprising a scaffold and a formwork and used for pouring concrete, reinforced concrete buildings or structures, and a bottom formwork of a poured beam or plate is formed by combining a top plate of a supporting column with a concrete beam and a plate formwork. When the concrete of the beam or the plate is cured to a certain degree, the template is dismantled through the early dismantling mechanism, and the pouring beam or the plate can be completely dismantled when being continuously supported to the concrete strength specified by the specification by the top plate of the support column. The early-disassembled template is used for layer transfer or field transfer, so that the construction period is shortened or advanced, the labor productivity of building construction is improved, the investment quantity of the template can be reduced, and the construction cost is reduced.

In the prior art, a plurality of early-dismantling support structures exist, but the existing early-dismantling support structures are complex in composition structure, multiple in installation procedures and high in requirement on skills of constructors. In the actual implementation process, how to simply and conveniently realize the dismantling of part of the early-dismantling supporting piece, and the concrete roof which does not completely reach the form dismantling condition can be effectively supported, which becomes a difficult point in the early-dismantling construction process.

The invention with the publication number of CN103195241A solves the problems and discloses an early-dismantling supporting device for building engineering, which comprises a supporting upright post, wherein a template supporting top plate, a template supporting plate, a supporting working condition positioner (sleeve) and a bolt penetrate through the supporting upright post from top to bottom in sequence in a threaded mode.

Inserting the support upright column into a steel supporting top or a steel pipe meeting the height requirement, fixing a sleeve, a template support supporting plate and a template support top plate in sequence according to the specification, and finally installing a concrete template on the template support supporting plate; after concrete is poured into the concrete formwork, when the concrete reaches a certain strength, the bolt can be pulled out and the sleeve can be rotated downwards, so that the formwork supporting plate moves downwards, the space for disassembling the concrete formwork is moved out, and finally the concrete formwork is disassembled for the construction of the next construction layer.

Because the position of the bolt is fixed, the early-dismantling supporting device cannot be used for installing concrete formworks with other thicknesses, and the bolt needs to be dismantled to install the concrete formworks with other thicknesses. However, after the bolt is removed, since the bolt does not block the sleeve, the sleeve is easily misadjusted by a worker (the position of the sleeve is deviated after the sleeve is rotated due to miscollision of the worker), or is repeatedly adjusted (the number of the early-dismantling supporting devices is large, and the worker mistakenly adjusts the adjusted early-dismantling supporting device as an unadjusted early-dismantling supporting device for multiple times), so that the working hours are wasted.

A plurality of reinforcing plates 34 are fixed on the side wall of the connecting neck 33, the upper plate 31 and the lower plate 32 are fixedly connected with the reinforcing plates 34, and the reinforcing plates 34 are used for improving the bearing performance of the formwork support supporting plate 3. The concrete formwork is clamped between the upper plate 31 and the formwork support top plate 2, and the upper plate 31 and the formwork support top plate 2 are both provided with positioning holes 11 for fixing the concrete formwork.

As shown in fig. 1, a bearing 4 (dust bearing) is provided on the support column 1, and the formwork support plate 3 is located between the bearing 4 and the formwork support top plate 2. The supporting upright post 1 is sleeved with a corrugated pipe 10, one end of the corrugated pipe 10 is seamlessly connected with a lower plate 32 of the template supporting plate 3, and the other end of the corrugated pipe 10 is suspended and covers the bearing 4. By adopting the dustproof bearing 4 and the corrugated pipe 10, wet slurry in the concrete template or solid particles falling down when the concrete template is disassembled can be prevented from falling into the bearing 4, so that the service life of the bearing 4 is influenced.

As shown in fig. 3, the bearing 4 is composed of a bearing inner ring 41, a bearing outer ring 42, a plurality of steel balls located between the bearing inner ring 41 and the bearing outer ring 42, and a dust seal (not shown in fig. 3) for sealing gaps between the bearing inner ring 41 and the bearing outer ring 42.

As shown in fig. 1, a first collar 5 and a second collar 6 are further disposed on the support column 1, wherein the first collar 5 is coaxially and fixedly connected with the bearing inner ring 41. The side of the support column 1 is provided with external threads, the first lantern ring 5 is in threaded connection with the support column 1, and the bearing 4 can move along the length direction of the support column 1 by rotating the first lantern ring 5/the bearing inner ring 41.

As shown in fig. 3, the first collar 5 is provided with a through hole 5a, and the first collar 5 can be easily driven to rotate manually by inserting the plug pin 7 into the through hole 5 a.

The implementation principle of the embodiment is as follows: because the bearing inner ring 41 is indirectly screwed with the support column 1 through the first lantern ring 5, the bearing 4 can move along the length direction of the support column 1 by rotating the bearing inner ring 41 (inserting the bolt 7 into the through hole 5a of the first lantern ring 5), so that the maximum distance between the formwork support top plate 2 and the formwork support supporting plate 3 (corresponding to the thickness of the concrete formwork) is adjusted, and the method can be suitable for installing concrete formworks with different thicknesses.

After the bearing inner ring 41 is adjusted to a designated position on the support upright post 1, the second sleeve ring 6 is rotated to enable the through hole 6a to be communicated with the long hole 1a, and then the bolt 7 is used for being inserted into the through hole 6a and the long hole 1a in series, so that the bearing outer ring 42 is fixed relative to the support upright post 1, and at the moment, a worker can not rotate the bearing inner ring 41 due to accidental collision. When the position of the bearing inner ring 41 needs to be adjusted, the bolt 7 is detached, the second sleeve ring 6 is rotated to enable the through hole 6a to be communicated with the through hole 5a, then the bolt 7 is inserted into the through hole 5a, and the bearing inner ring 41 can be driven to rotate.

In summary, because the bolt 7 of the adjusted early-dismantling supporting device passes through the second lantern ring 6 and is inserted into the long hole 1a, the early-dismantling supporting device has obvious identification effect different from the unadjusted early-dismantling supporting device (the bolt 7 is not arranged in the long hole 1 a), so that the repeated adjustment of workers can be prevented; in the adjusted early-dismantling support device, the bolt 7 locks the bearing outer ring 42, and the through hole 5a on the first sleeve 5 cannot be exposed, so that the bearing inner ring 41 cannot be rotated, and the error adjustment of workers can be prevented.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
