Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction especially relates to a floor concrete pouring thickness control device. BACKGROUND

[0002] During the floor concrete construction, the floor slab surface elevation being poured needs to be controlled, and the pouring thickness of the floor concrete also needs to be controlled. The self-made steel bar inserting rod method is a common method for controlling the pouring thickness of the concrete. For example, a floor thickness controller disclosed in application No. CN202222885888.4 cannot meet the construction requirements of different floor thicknesses, so multiple specifications for different thickness floors need to be prepared.

[0003] Application No. CN201920276146.7 discloses a floor thickness measuring device. The length of the measuring rod, the length of the scale, and the reading are adjusted according to the design thickness requirements of the floor to ensure that the floor thickness measuring device is at an appropriate height, effectively ensures the floor thickness, and ensures the quality of the concrete construction. The working principle is as follows: in the normal state, the bottom of the measuring rod is flush with the bottom of the supporting plate. When in use, the measuring rod of the measuring device is directly inserted into the concrete, the supporting plate on the outer sleeve is subjected to the resistance of the concrete and moves relative to the measuring rod, and the actual thickness of the floor is read through the scale on the upper end of the outer sleeve. Although this measuring device can be adjusted according to the design thickness of the floor, the applicant believes that it has the following defects:

[0004] The device does not take into account the self-weight of the outer sleeve and the supporting plate. After the measuring rod is inserted into the concrete, the outer sleeve and the supporting plate will sink into the concrete under the action of their self-weight, thus causing inaccurate measurement of the floor thickness.

[0005] Therefore, the present application provides a floor concrete pouring thickness control device that can measure different floor thicknesses accurately to solve the above problems. UTILITY MODEL CONTENTS

[0030] Example 1

[0031] This embodiment provides a device for controlling the thickness of concrete pouring in floor slabs, as shown in the attached document. Figure 1 As shown, it includes a rod 1, a handle 2, a sleeve 3, a limiting plate 4, an elevation indicator plate 5, a positioning ring 6, and a tension spring 7, wherein:

[0032] The bottom of the insertion rod 1 is designed as a pointed cone to reduce resistance when inserting into the concrete, making it easier to insert smoothly into the bottom of the concrete. The handle 2 is fixedly installed on the top of the insertion rod 1, making it easier to hold the handle and insert the insertion rod into the concrete, making insertion less strenuous.

[0033] As attached Figure 1 and attached Figure 3 As shown, the top of the sleeve 3 is provided with a limiting plate 4, and the bottom is provided with an annular elevation indicator plate 5. The sleeve, the limiting plate, and the elevation indicator plate form a whole and are movably sleeved on the insertion rod 1. In this embodiment, it is preferably movably sleeved on the insertion rod with circumferential limiting. The specific circumferential limiting method is as follows: In one embodiment, the cross-section of the insertion rod 1 is a regular polygon (which can be an equilateral triangle, a square, etc.), and the inner circle of the limiting plate 4 is set as a regular polygonal hole that matches the insertion rod. In another embodiment, as shown in the attached figure... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4As shown, the cross-section of the insertion rod 1 is circular, and a limiting plane 1.1 is provided on the insertion rod 1 along its length direction, so that the cross-section of the insertion rod at the limiting plane is "D" shaped, and the inner ring of the limiting plate 4 is set as a "D" shaped hole.

[0034] As attached Figure 1 As shown, the positioning ring 6 is movably sleeved on the insertion rod 1 along its length, and is housed within the sleeve 3. The position of the sleeve and its elevation indicator plate can be controlled by adjusting the position of the positioning ring on the insertion rod. A locking bolt 8 is screwed onto the positioning ring 6, which can be loosened or tightened to release or fix the positioning ring. In this preferred embodiment, the positioning ring 6 and the insertion rod 1 are assembled using the same circumferential limiting method as shown above. To control the adjustment amount, this embodiment provides a scale 1.2 on the insertion rod 1. If the cross-section of the insertion rod is a regular polygon, the scale is set on one of the outer surfaces of the insertion rod; if the cross-section of the insertion rod is circular, the scale 1.2 is set on the limiting plane 1.1 of the insertion rod 1. When the bottom surface of the elevation indicator plate is flush with the bottom of the insertion rod, the position where the positioning ring contacts the limiting plate is the 0 scale. To facilitate viewing the position of the positioning ring inside the sleeve and to facilitate adjustment of the positioning ring, as shown in the attached figure... Figure 3 As shown, in this embodiment, an adjustment groove 3.1 is provided on the sleeve 3 at the position opposite to the scale 1.2. The width of the adjustment groove should be greater than the width of the regular polygon's transformation or limiting plane, and the locking bolt 8 protrudes outside the adjustment groove 3.1.

[0035] One end of the tension spring 7 is fixedly connected to the handle 2, and the other end is fixedly connected to the limiting plate 4, which is used to pull the sleeve 3 so that the elevation indicator plate is always above the concrete floor.

[0036] In practice, first adjust the position of the positioning ring on the insert rod according to the design thickness of the concrete slab; then insert the control device into the bottom of the concrete (in contact with the formwork), and press the sleeve down until the limiting plate contacts the positioning ring, as shown in the attached diagram. Figure 5 As shown, at this time, the distance between the elevation indicator board and the formwork is equal to the set floor slab thickness H. Observe the poured concrete. If the concrete is higher than the elevation indicator board, it means that the concrete is too thick and needs to be leveled according to the position of the elevation indicator board. If the concrete is lower than the elevation indicator board, it means that the concrete is too thin and needs to be filled with concrete.

[0037] Example 2

[0038] Based on Example 1, as shown in the appendix Figure 1 and attached Figure 4As shown, the top of the insertion rod 1 is provided with a threaded stud 1.3, the bottom of the handle 2 is provided with a threaded hole for screwing with the threaded stud, and a washer 9 is further arranged between the handle 2 and the insertion rod 1, one end of the tension spring 7 is welded with the washer 9, and the other end is welded with the limiting plate 4. This design makes the control device form an assembled structure, facilitates quick replacement after part damage, and reduces maintenance cost.

[0039] During specific assembly, the positioning ring is first installed on the insertion rod, then the top of the insertion rod is inserted into the bottom of the sleeve, until the insertion rod is exposed from the washer, and then the handle is screwed on the insertion rod.

[0040] Example Three

[0041] On the basis of the example one or the example two, as shown in the accompanying drawings, Figure 1 As shown, the top of the insertion rod 1 is provided with a threaded stud 1.3, the bottom of the handle 2 is provided with a threaded hole for screwing with the threaded stud, and a washer 9 is further arranged between the handle 2 and the insertion rod 1, one end of the tension spring 7 is welded with the washer 9, and the other end is welded with the limiting plate 4. This design makes the control device form an assembled structure, facilitates quick replacement after part damage, and reduces maintenance cost.

[0042] Preferably, the bottom outer wall of the handle 2 is provided with a first arc-shaped inner recess 2.1, the top outer side of the push block 10 is provided with a second arc-shaped inner recess 10.1, and the first arc-shaped inner recess 2.1 and the second arc-shaped inner recess 10.1 are smoothly and transitionally connected, so that the handle and the push block form a holding part. This design facilitates one-handed operation. During specific operation, the device is inserted into the concrete by one hand holding the holding part, and then the push block is pushed downward until the limiting plate on the sleeve contacts the positioning ring.

[0043] The above-described embodiments are merely examples of the utility model, and do not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion according to the content of the utility model specification, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
