Description

Auxiliary device for measuring the reserved hole position of the pad stone

technical field

The utility model belongs to the technical field of measuring tools in the construction of prefabricated beam frame pad stone supports, and in particular relates to an auxiliary device for measuring the position of holes reserved in pad stones.

Background technique

Before various prefabricated beams are erected on the pad stone support, it is necessary to measure and check the reserved anchor bolt hole positions on the pad stone. Before the measurement, it is necessary to manually measure each reserved hole with a tape measure according to the center line and elevation of the pad stone support. Check the position and depth of the beam. Since manual measurement with a tape measure can only measure points but not lines and surfaces, it is difficult to control the measurement accuracy, resulting in large hole position deviations during the beam erection process, and the phenomenon that it cannot be laid. It is necessary to Rework processing. Due to the inaccurate measurement in the early stage, the girder erection process can only be hoisted and aligned repeatedly. However, the girder is heavy and requires a special hoisting device, which increases the cost and is difficult to operate. It will also delay the construction period and affect the normal construction progress.

Contents of the invention

In order to quickly and accurately measure and check the reserved anchor bolt holes on the pad stone, the utility model provides an auxiliary device for measuring the position of the reserved hole position of the pad stone.

The utility model adopts the following technical solutions:

An auxiliary device for measuring the reserved hole position of a pad stone, including a base and a measuring rod for plugging in, the base includes a top seat with a through hole and several hollow vertical rods connected with the top seat, each hollow The uprights are vertically connected to the lower surface of the through hole of the top base one by one respectively and the aperture of the through hole is equal to the inner diameter of the hollow upright. Hollow pole plug fit.

The number of the hollow vertical rods is equal to the number of the reserved anchor bolt holes on the pad stone, and the relative positional relationship between each hollow vertical rod and the cross line is the same as the relative positional relationship between the reserved anchor bolt holes and the central line of the pad stone.

The diameter of the hollow vertical rod is smaller than the diameter of the reserved anchor bolt hole.

The diameter of the measuring rod is equal to the diameter of the anchor bolt matched with the reserved anchor bolt hole.

The height of the measuring rod is at least 20cm greater than the depth of the reserved anchor hole.

The utility model has the following beneficial effects:

1. The auxiliary device described in this utility model is made according to the theoretical design value of the reserved anchor bolt hole on the pad stone, and then the auxiliary device and the reserved anchor bolt hole overlap and its measuring rod extends out of the top seat The height of the upper surface is checked against the anchor hole, and the measurement accuracy is high;

2. This auxiliary device can quickly measure the position and depth of the anchor bolt hole reserved on the check pad, which is more convenient and efficient than the traditional manual measurement method;

3. The auxiliary device can be made of ordinary steel plates, steel pipes and other materials, the production method is simple, and can be widely used in bridges, civil engineering and other constructions;

4. Using this device, the reserved holes on the pad stone can be checked before the construction of the beam, which avoids the impact on the construction period of the beam.

Detailed ways

In conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:

As shown in Figures 1 and 2, the auxiliary device for measuring the reserved hole position of the pad stone includes a base and a measuring rod 2 for plugging in, and the base includes a top seat 1 with a through hole and a top seat 1 A number of hollow vertical rods 3 connected, each hollow vertical rod 3 is vertically connected to the lower surface of the through hole of the top seat 1 respectively one by one, and the aperture of the through hole is equal to the inner diameter of the hollow vertical rod 3, and the upper and lower surfaces of the top seat 1 are uniform. A reticle 4 passing through its center is provided, and the measuring rod 2 is inserted and matched with the hollow vertical rod 3 .

The number of the hollow vertical rods 3 is equal to the number of reserved anchor bolt holes 6 on the pad stone 5, and the relative positional relationship between each hollow vertical rod 3 and the cross line 4 is the same as that of the reserved anchor bolt holes 6 and the centerline of the pad stone 5. The relative positional relationship is the same. The number of reserved anchor bolt holes 6 and hollow vertical rods 3 is generally four, that is, after the number and position design of the reserved anchor bolt holes 6 on the pad stone 5 are determined, four hollow vertical rods are welded on the lower surface of the top seat 1. Rod 3, the distance between each hollow vertical rod 3 and the center of the top seat is exactly the same as the distance between the reserved anchor bolt hole 6 and the center of the pad stone. Fully inserted into the reserved anchor hole 6 for checking.

Among them, when designing the base, the height of the hollow vertical rod 3 should be equal to the height of the support sleeve installed on the upper part of the pad stone; the diameter of the measuring rod 2 should be equal to the diameter of the anchor bolt matched with the reserved anchor bolt hole 6, In order to make the measuring rod 2 play the role of replacing the anchor bolt to check the anchor bolt hole; because the actual depth of the reserved anchor bolt hole 6 may be larger than the design depth, in order to improve the accuracy of the check and facilitate the operation and observation, the measuring rod 2 The height is at least 20cm larger than the depth of the reserved anchor bolt hole 6.

The concrete use method of this utensil is: at first make the top seat cross line of this auxiliary utensil coincide with the center line of pad stone 5, then insert the hollow vertical pole 3 of auxiliary utensil into the reserved anchor bolt hole 6 on the pad stone 5 to use The utensil is stuck on the pad stone, if the four hollow vertical rods 3 can be inserted one by one, the reserved hole position on the pad stone 5 is qualified, otherwise if there is a hollow vertical rod that cannot be inserted, it means that the corresponding hollow vertical rod The position of the anchor bolt hole is unqualified and needs to be further corrected and rechecked. After checking the position of the reserved anchor bolt hole, insert the measuring rod 2 into each hollow vertical rod 3 in turn until the bottom position of the reserved anchor bolt hole. The height from the top of the measuring rod 2 to the upper surface of the top seat 1 can be calculated Find out the hole depth of the reserved anchor bolt hole, and judge the position of the reserved anchor bolt hole by observing the situation that the measuring rod 2 is inserted into the bottom of the hole.
