Description

Technical Field

[0001] The utility model belongs to the technical field of building construction tool design, in particular to a measuring tool used for installing an enamel steel plate connection angle code. Background Art

[0002] In the tunnel reconstruction project, the tunnel structure wall has poor flatness due to concrete expansion, later water seepage, and different inclinations of the tunnel ramps. In order to ensure that the enameled steel plate is arranged vertically on the road surface, different specifications of connection angle codes should be used at different positions on the wall.

[0003] The traditional construction process of enameled steel plates is: measurement → layout deepening → laying out → angle code and keel construction → installation and adjustment of enameled steel plates. During the construction of enameled steel plates, the installation accuracy of angle codes and keels is an important factor affecting the construction quality of enameled steel plates. In traditional construction, after overall measurement and laying out, the positions of the keels and connecting angle codes of the enameled steel plates are usually determined first, and the surface lines are laid out. Then, the surface lines of the enameled steel plates are projected with the help of an infrared level meter, and the length of the connecting angle codes required at each keel section is measured with a tape measure, and marked on the wall with a marker. This approach has the following defects:

[0004] Porcelain steel plates are generally large in size, and the common installation height in tunnels and subways is generally above 2.5m. If a tape measure is used to measure the required connection angle code specifications, a mobile operating platform with a height of 2m or above needs to be set up for people to stand on the platform for operation. If the mobile operating platform is not set up high enough, the construction workers cannot reach the angle code position, and errors are likely to occur when using a tape measure to measure, resulting in incorrect connection angle code specifications. When the enameled steel plates are subsequently installed, they are prone to dismantling, rework, and replacement due to angle code specifications, which can easily cause unnecessary losses. In addition, since a mobile operating platform needs to be set up, there are certain risks in working at height and on the mobile operating platform.

[0005] Therefore, how to improve the measurement speed and accuracy of the connection angle code specifications and reduce the construction risks during the construction of the angle code and keel has become a topic that needs urgent consideration. To this end, the utility model designs a fast, accurate and adjustable measuring device for enameled steel plates. Utility Model Content

[0007] The present invention achieves the above technical objectives through the following technical means.

[0008] According to the measuring tool used for installing the angle code for connecting the enameled steel plate, it includes an aluminum alloy ruler body, which is a three-section structure. The left and right sections are connected to the middle section through a rotating shaft. The left and right sections can rotate freely around the rotating shaft to realize the expansion or folding operation of the aluminum alloy ruler body; a locking screw is installed at each end of the middle section of the aluminum alloy ruler body, and a locking screw is also installed on each of the left and right sections. A freely rotatable lock buckle is installed on the locking screw of the middle section, and an opening matching the locking screws on the left and right sections is provided at the other end of the lock buckle, and the aluminum alloy ruler body is fixed by tightening the locking screw; a scale is movably installed on one section of the three-section aluminum alloy ruler body through a rotating shaft.

[0009] Furthermore, a handle is installed on another section of the three-section aluminum alloy ruler body, and the handle includes a hard plastic fixed on the aluminum alloy ruler body, and a rubber anti-slip part is installed on the hard plastic.

[0010] Furthermore, the locking screw is composed of a flat head screw and a plastic cap.

[0011] The utility model has the following beneficial effects:

[0012] The utility model is mainly applicable to the construction of wall enameled steel plate angle brackets and keels in renovation projects, and can quickly measure the length of the connection angle brackets required for uneven walls, and can quickly and accurately position and install the curtain wall keels.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0018] like Figures 1 to 3 As shown, the measuring tool for installing the angle bracket for connecting the enameled steel plate according to the utility model comprises a rotating shaft 1, a locking screw 2, a locking buckle 4, a handle 3, a scale 5, a rotating shaft 6, and an aluminum alloy ruler body 7.

[0019] like Figure 1 , 3 As shown, the aluminum alloy ruler body 7 is a three-section structure, consisting of three sections of aluminum profile square tubes with a cross-sectional size of 400×30×30mm. A rotating shaft 1 is installed between the left and right sections and the middle section. The left and right sections can rotate freely around the rotating shaft 1, thereby realizing the unfolding or folding operation of the aluminum alloy ruler body 7. It is convenient to use and can reduce the occupied space when stored. The unfolding schematic diagram of the aluminum alloy ruler body 7 is shown in FIG. Figure 3 Specifically, the rotating shaft 1 is composed of a pin with a diameter of 5 mm and a length of 40 mm and two circular blades.

[0020] like Figure 1 , 3 As shown, Figure 1 , 3 As shown, the locking screw 2 is composed of a flat head screw with a diameter of 6mm and a plastic cap with a diameter of 10mm. A locking screw 2 is installed on each of the two sections of the aluminum alloy ruler body 7 connected to the rotating shaft 1. The two locking screws 2 on the middle section of the aluminum alloy ruler body 7 are both equipped with a lock buckle 4. The lock buckle 4 is made of stainless steel stamping with a size of 50×12×1mm. A locking screw hole is reserved at one end of the lock buckle 4 and connected to the locking screw 2. When the locking screw 2 is not tightened, the lock buckle 4 can achieve 360° free rotation. The other end of the lock buckle is provided with an opening for clamping with the remaining locking screws. When the aluminum alloy ruler body 7 is unfolded or retracted, the opening of the lock buckle 4 is clamped with the corresponding locking screw 2. By adjusting the tightening degree of the locking screw 2, the aluminum alloy ruler body 7 can be fixed to prevent the aluminum alloy ruler body 7 from rotating.

[0021] like Figures 1 to 3 As shown, the handle 3 includes a hard plastic with a length of 15 cm and a width of 1 cm. The hard plastic is fixed on the upper surface and the lower surface of one section of the three-section aluminum alloy ruler body 7. A rubber anti-slip part is installed on the hard plastic. The handle 3 is the gripping part when the handheld measuring tool is used for measurement. The design of the anti-slip part can prevent the aluminum alloy ruler body 7 from sliding.

[0022] like Figure 1 , 3As shown, the scale 5 is made of an aluminum profile with a size of 400×200×100mm, with a graduation value of 1mm and a measuring range of 350mm. The scale 5 is rotatably mounted on another section of the three-section aluminum alloy ruler body 7 through a rotating shaft 6, and the rotation angle range is: 0°~270°, which is used to measure the length required for the angle code of the enameled steel plate connection during construction. The rotating shaft 6 is a 3mm diameter blind rivet, which is used to fix the scale 5 in the aluminum alloy ruler body 7 and becomes the rotating axis of the scale 5, so that the scale 5 can rotate in a fixed direction, and the maximum rotatable angle is 270°.

[0023] In actual construction, the aluminum alloy ruler body 7 is unfolded, fixed, and locked to form a 1.2m long L-shaped measuring ruler together with the scale 5; after use, the scale 5 can be rotated 270° and stored in the aluminum alloy ruler body 7 to avoid damage to the scale 5.

[0024] The utility model is used in the positioning and installation process of the connection angle code of the enameled steel plate. By unfolding the scale 5 and cooperating with the finished surface line projected by the infrared level meter, the specifications of the connection angle code at different connection angle code positions on the wall can be accurately measured, which saves the process of setting up a mobile operating platform in conventional construction, speeds up the construction progress and positioning accuracy, and reduces the construction risk in the measurement construction. The specific construction process is as follows:

[0025] Step 1: Dismantle, measure and lay out;

[0026] After removing the original decorative panels on the wall, lay out the angle codes and keel positioning lines of the enameled steel plates according to the construction drawings to complete the surface lines.

[0027] Step 2: Determine the size of the connection angle;

[0028] After measuring and laying out the keel, angle code positioning line and completed surface line, first set up the infrared level according to the completed surface line, and project the wall enameled steel plate to complete the surface line. Then unfold the measuring device tool, hold the grip 3 of the measuring tool, and place the zero scale of the ruler 5 close to the connection angle code positioning position, and keep the ruler 5 as vertical as possible to the wall. Then observe the position where the laser emitted by the infrared level intersects with the ruler 5, and according to the scale of the corresponding position of the completed surface line projected by the infrared level on the ruler 5, the specifications required for the connection angle code at this location are obtained. And mark the specifications on the wall with a marker, and then you can count and order the connection angle code based on this. Repeat the above steps to achieve batch measurement of the connection angle code specifications.

[0029] Step 3: Install the connecting angle brackets and keels;

[0030] Use an electric drill to drill holes. After drilling, clean the dust and powder in the holes, then install the angle code and fix it to the tunnel wall with M10 galvanized self-cutting mechanical anchor bolts. During the installation process, ensure that the expansion bolts are reliably connected to the structural wall.

[0031] Step 4: Install the enameled steel plate;

[0032] The installation of the enameled steel plate is carried out from bottom to top. When installing the enameled steel plate, align the socket of the enameled steel plate with the socket of the vertical keel hook and push it in and hang it on the keel. For the installed plate, check whether the enameled steel plate is perpendicular to the road surface at any time during the installation process.

[0033] The embodiments are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essential content of the present invention belong to the protection scope of the present invention.
