Description

Adjustable cast-in-place slab concrete thickness control instrument

Technical Field

The utility model relates to a construction technical field specifically is a cast-in-place board concrete thickness control instrument of adjustable.

Background

The cast-in-place concrete construction technology is a concrete construction process for in-situ casting according to engineering positions. Because cast-in-place concrete is often influenced by weather factors such as wind, rain, temperature, humidity and the like, site conditions, transportation distance, structural shape and structural position, corresponding measures are respectively adopted according to actual conditions and possible conditions in the aspects of raw material preparation, stirring process, transportation method, casting mode, maintenance method and the like, so that the interference and damage of various adverse conditions are avoided or reduced in the processes from preparation, forming to hardening of the concrete.

At present, the common mode for controlling the thickness of the concrete floor slab is to mark a 50cm or 60cm line on a column rib, pull the 50cm or 60cm line when the concrete is poured to cover the floor, and then measure the 50cm or 60cm downwards to control the thickness of the slab. However, the method often has a blind area, so that only the part with the stay wire can be measured when the stay wire is pulled, and the part which cannot be pulled cannot be measured. Therefore, the plate thickness control is not ideal, and the measurement error exists.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cast-in-place board concrete thickness of adjustable control instrument is in order to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

adjustable cast-in-place board concrete thickness control instrument, including support and adjustment mechanism, the support is connected gradually into the triangle-shaped structure by three connecting rods that the specification is the same end to end, adjustment mechanism fixes on the support, and adjustment mechanism includes three regulation pole and three adjusting sleeve, and is three adjusting sleeve is located the position department on the three summit of support respectively, and every adjusting sleeve the central axis with the face at support place is mutually perpendicular, adjust pole and adjusting sleeve sliding connection, and adjust the slip direction of pole with the face at support place is perpendicular.

Preferably, the side wall of the adjusting rod is provided with an external thread along the length direction of the adjusting rod, and the inner wall of the adjusting sleeve is provided with an internal thread matched with the external thread of the adjusting rod along the length direction of the adjusting sleeve.

Preferably, the adjusting rod is of a conical structure, and the outer side wall of the adjusting rod is further provided with scale marks.

Preferably, the connecting rod and the adjusting sleeve are made of stainless steel materials, and the connecting rod and the adjusting sleeve are fixed together in a welding mode.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model discloses compensate current control cast in situ concrete floor thickness shortcoming accurate inadequately, can effectively control cast in situ concrete board thick, have structural design is reasonable, easy operation, convenient to use's advantage.

(2) The utility model discloses a threaded connection mode will adjust the pole and be connected with adjusting sleeve, makes simply, but reuse has reduced use cost to the installation is simple, the installation accuracy is high, can control cast-in-place reinforced concrete floor thickness effectively, accurately.

(3) The utility model discloses an adjusting sleeve will adjust pole sliding connection on the support, play the effect of support holder on the one hand, conveniently adjust the height of support on the one hand, because the support is the triangle-shaped structure, have better stability to support well through adjusting the pole and waiting to water on concrete slab, the phenomenon of tumbling can not appear, so that accurately control cast-in-place reinforced concrete floor thickness, be applicable to the concrete slab of pouring different thickness.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

adjustable cast-in-place slab concrete thickness control instrument, including support 2 and adjustment mechanism, support 2 is by the same connecting rod end to end of three specifications connect gradually the triangle-shaped structure, adjustment mechanism fixes on support 2, and adjustment mechanism includes three regulation pole 1 and three adjusting sleeve 3, and is three adjusting sleeve 3 is located the position department on the three summit of support 2 respectively, and every adjusting sleeve 3 the central axis with the face at support 2 place is mutually perpendicular, adjust pole 1 and adjusting sleeve 3 sliding connection, and adjust the slip direction of pole 1 with the face at support 2 place is perpendicular.

In this embodiment, be equipped with the external screw thread along its length direction on adjusting the lateral wall of pole 1, the inner wall of adjusting sleeve 3 is equipped with the internal thread with adjusting the external screw thread looks adaptation of pole 1 along its length direction, and convenient the regulation adopts threaded connection's mode for adjust the precision higher.
