Abstract

The utility model discloses an adjustable exploration drill for testing the thickness of concrete. The exploration drill comprises a first construction piece and a second construction piece. The first construction piece comprises a rectangular frame; the middle position of each edge of the frame is provided with a welded L shape hook. Two symmetrically opposite edges of the rectangular edge are both provided with a welded screw nut each. The second construction piece comprises a T shape frame whose transverse bar is provided with a hanging plumb bob. The T shape frame is vertically inserted along with the geometrical center of the rectangular frame. The first construction piece is clamped tight by two screw bolts which are connected with the two screw nuts arranged at the pre-set positions. The beneficial effects of the exploration drill comprise that it is simple to make and convenient to dismount. Further, it effectively utilizes wasted concrete reinforcing bars, screw bolts and screw nuts; by the introduction of an adjusting apparatus, the exploration drill is capable of doing a spot check and control on the thickness of various floors with varied thickness. With the exploration drill, makeup measures can be made in the process of preparing concrete so as to guarantee overall smoothness and thickness of a floor.

Description

Detect the adjustable spy pricker of concrete thickness

Technical field

The utility model relates to adjustable spy pricker, relates in particular to the adjustable spy pricker that detects concrete thickness.

Background technology

At present; in the middle of a lot of engineering constructions; the thickness of controlling concrete slab generally adopts the modes such as hanging wire, and due to when constructing, concrete mobility causes the centre position of two hung control lines to occur low-lying position; this low-lying being in while constructing is not easy to be found; after concrete final set, but have and cannot remedy, cause that floor is uneven, thickness is not enough, gently affects attractive in appearance; the protective layer thickness that affects the superiors' reinforcing bar of plate when situation is serious, affects structural quality.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of adjustable spy pricker that has guaranteed the integral smoothness of floor and the detection concrete thickness of slab thickness is provided.

In order to achieve the above object, the technical solution adopted in the utility model is:

A kind of adjustable spy pricker that detects concrete thickness of the present utility model, it comprises member one and member two, described member one comprises rectangular frame, on the centre position, every one side of described rectangular frame, be welded with respectively a L-type crotch, on one group of opposite side of rectangular frame, be welded with respectively a nut, described member two comprises T shape framework, on described T-shaped framework horizontal bar, hang with a plummet, T shape framework vertically inserts along the geometric center of rectangular frame, member one can clamp by being connected to the termination of two bolts in nut at preposition.

The beneficial effects of the utility model are: make simply, and easy accessibility, and can effectively utilize steel scrap muscle, bolt, nut, and can pass through regulating device, can carry out thickness selective examination and control to the floor of various thickness.Concrete construction takes repairing measures to guarantee integral smoothness and the slab thickness of floor in time.

Embodiment

A kind of adjustable spy pricker that detects concrete thickness of the present utility model as shown in drawings, it comprises member one and member two, described member one comprises rectangular frame 2, on the centre position, every one side of described rectangular frame 2, be welded with respectively a L-type crotch 4, on one group of opposite side of rectangular frame 2, be welded with respectively a nut 1, in two described nuts, be connected with bolt 3, described member two comprises T shape framework 6, on described T-shaped framework horizontal bar, hang with a plummet 5, T shape framework 6 vertically inserts along the geometric center of rectangular frame, between member one and member two, be now contactless state, according to the thickness of wish detection concrete slab, determine the relative position on T-shaped framework of member one, member one can clamp by being connected to the termination of two bolts in nut at preposition.Now two groups of bolt ends all abut against on the vertical reinforcement of member two, and rectangular frame 2 can be fixed on T-shaped framework 6.

The using method of this device is:

1. by (the T-shaped framework of member one vertically inserts along the geometric center of rectangular frame, is now contactless state between member one and member two) in the rectangular frame in member two insert members one.

2. according to the thickness of the concrete slab that will detect, by the location positioning of member one (getting L-type crotch equates with the thickness of the concrete slab that is about to detect to the distance H of visiting pricker bottom).The detection of the plate of the different-thickness in engineering can regulate tight position, the school on T-shaped framework by bolt.

3., after the height and position of member one on T-shaped framework vertical reinforcement determined, with two M20 bolts, insert nut, tight with spanner school.Now two groups of bolt ends all abut against on the vertical reinforcement of member two, and member one can be fixed on member two.

4. whole device has been assembled, and during detection, by visiting in the concrete that the vertical insertion of pricker newly builds (using the plummet that installs as verticality with reference to), all floating on concrete surface concrete slab, to build thickness qualified just for the L-type crotch of four direction.The thickness that in figure, H is concrete slab to be detected.

Claims

1. an adjustable spy pricker that detects concrete thickness, it is characterized in that: it comprises member one and member two, described member one comprises rectangular frame, on the centre position, every one side of described rectangular frame, be welded with respectively a L-type crotch, on one group of opposite side of rectangular frame, be welded with respectively a nut, described member two comprises T shape framework, on described T-shaped framework horizontal bar, hang with a plummet, T shape framework vertically inserts along the geometric center of rectangular frame, member one can clamp by being connected to the termination of two bolts in nut at preposition.
