Embodiment 1

[0037] Such as figure 1 and figure 2 The shown a concrete floor pre-embedded pipeline marking device that can avoid drilling damage includes a main shell 2 with a circular cross section, a partition 10 is fixed inside the main shell 2, and the main shell The part of the body 2 above the partition 10 forms a paint storage chamber 12 for storing paint, and the part of the main housing 2 below the partition 10 forms a feeding chamber, and the bottom of the main housing 2 is opened. There is a discharge port 9 communicated with the lower material chamber, the discharge port 9 is a bar-shaped port, the upper end of one side of the main housing 2 is connected with the feed pipe 7 communicated with the paint storage chamber 12, the partition The middle part of the plate 10 is provided with a blanking through hole 17 communicating with the paint storage cavity 12 and the blanking cavity, and a vertical rod 16 is arranged on the vertical central axis in the main housing 2, and the ve...

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is:

[0043] In this example, if figure 1 As shown, a handle 27 is fixed on the top of the secondary housing 3 , and a brush 28 at the discharge port 9 is fixed on the bottom of the main housing 2 . The device can be conveniently held by the handle 27; the paint discharged from the discharge port 9 can be smoothly drained by the brush 28.

[0044] In this example, if Figure 5 As shown, the cross section of the main housing 2 is pitch-shaped, and the height of the annular vertical surface 112 is half of the travel of the vertical rod 16 in one direction. In the initial state, the junction of the annular vertical surface 112 and the lower annular inclined surface 113 blocks the lower port of the feeding through hole 17; when the driving mechanism starts to drive the vertical rod 16 to move downward, the vertical rod 16 drives the valve body block 11 moves downward, before the upper end of the annular vertical sur...

Abstract

The invention discloses a concrete floor pre-embedded pipeline marking device and method capable of avoiding drilling damage, which belongs to the field of building construction. For the partition of the material through hole, the vertical center line of the main shell is provided with a vertical rod, and the bottom of the vertical rod is fixed with a valve body block for blocking the material through hole; the method is to pre-embed it on the formwork Draw the paint marking line at the position of the line pipe; then perform operations such as pouring concrete. After the formwork is removed, the paint marking line on the formwork is printed on the concrete floor, and the direction of the paint marking line is the direction of the pre-embedded line pipe in the concrete. The marking device provided by the present invention can draw paint marking lines with better uniformity, and the width of the paint marking lines is adjustable; the provided method can make the paint marking lines indicate the position of the pre-embedded electric wire pipe, and avoid Open the electrical conduit to avoid damage to the conduit and protect the conduit.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a device and method for marking pre-embedded pipelines on concrete floors that can avoid damage to drilling holes. Background technique [0002] Reinforced concrete floor slab has high strength, good rigidity, good fire resistance and durability, and good plasticity. It is convenient for industrial production in our country and is the most widely used. According to different construction methods, it can be divided into three types: cast-in-place type, assembled type and assembled integral type. Among them, cast-in-place slabs are suitable for cast-in-place reinforced concrete and prestressed concrete hollow slabs in industrial and civil buildings, and have the characteristics of saving materials and labor. [0003] At present, the construction process of the existing cast-in-place reinforced concrete floor slabs is: setting out, forming and erecting the formwork, making and ...
