Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a precise positioning device for reserved holes of a wall support attached to an exterior wall of a building. Background Art

[0002] With the development of my country's construction industry, there are more and more high-rise buildings, and more and more vertical transportation machinery and equipment are used, such as tower cranes. During the structural construction of this type of machinery and equipment, the holes required for the wall supports must be reserved in advance. The accuracy of the reserved holes determines the difficulty of installing the wall supports in the later stage. If the reserved holes are inaccurate, not level or skewed, the attached supports cannot be installed and need to be reworked and drilled. Sometimes it is easy to break the steel bars in the wall, affecting the safety of the structure. Summary of the invention

[0003] The purpose of the utility model is to solve the problem raised in the background technology and to provide a precise positioning device for reserved holes of a wall support attached to an exterior wall of a building.

[0004] The technical solution of the utility model to achieve the above purpose is:

[0005] A precise positioning device for reserved holes of wall supports attached to the exterior wall of a building, comprising an exterior wall embedded structure and an infrared positioning structure, characterized in that the exterior wall embedded structure comprises an inner plywood, connecting bolts, an outer plywood, and a positioning nut, the inner plywood is fixedly connected to the connecting bolts, the outer plywood is sleeved on the connecting bolts, and the connecting bolts are engaged with the positioning nuts; the infrared positioning structure comprises a bracket, a connecting shaft, a bearing, a pointer, a dial, and an infrared transmitter, the bracket is fixedly connected to the connecting shaft, the connecting shaft is fixedly connected to the inner side of the bearing, the outer side of the bearing is fixedly connected to the pointer, the dial is fixedly connected to the connecting shaft, and the pointer is fixedly connected to the infrared transmitter.

[0006] Preferably, a PVC tube is provided on the connecting bolt, and the PVC tube is sleeved on the connecting bolt.

[0007] Preferably, the bracket is provided with a magnet, and the magnet is fixedly connected to the bracket.

[0008] Preferably, a vial bubble is provided on the pointer, and the vial bubble is fixedly connected to the pointer.

[0009] Preferably, the diameter of the connecting bolt is consistent with the bolt diameter of the wall-mounted support and the angle between the connecting bolt and the inner clamping plate is 90°.

[0010] The utility model provides a precise positioning device for reserved holes of a wall support attached to a building exterior wall, which has the following beneficial effects:

[0011] Through its structural design, the device installs the support on the standard section of the mechanical equipment, determines the angle of the wall-mounted rod according to the manual of the mechanical equipment, and then turns the pointer. The pointer rotates on the connecting shaft through the bearing, and the pointer angle is observed through the dial until it is consistent with the specified angle in the manual, and then the infrared transmitter is turned on. The infrared transmitter emits a crosshair, and the hole position is marked on the outer wall according to the crosshair emitted to the outer wall and a hole is punched. After the drilling is completed, the installation of the outer wall embedded structure can be started. When installing the outer wall embedded structure, the connecting bolts are inserted into the holes, and then the connecting bolts are passed through the outer wall and the outer plywood and connected and fixed with positioning nuts. After the outer wall embedded structure is fixed, the pouring of concrete can be started. The concrete is not easy to move or deform during the pouring process, and the accuracy is high. After the pouring is completed, the positioning nuts can be removed to remove the inner plywood, the connecting bolts and the outer plywood from the outer wall, which greatly reduces the time for the later installation of the wall-mounted support and also reduces the hidden dangers of re-punching in the later stage.

[0025] In the present invention, a PVC tube 3 is provided on the connecting bolt 102 , and the PVC tube is sleeved on the connecting bolt 102 . The size of the opening, the horizontality and the verticality of the position can be checked through the PVC tube 3 .

[0026] In the utility model, a magnet 4 is provided on the bracket 201, and the magnet 4 is fixedly connected to the bracket 201. The support 201 can be fixed to the standard node more easily by the magnet 4.

[0027] In the present invention, a vial bubble 5 is provided on the pointer 204, and the vial bubble 5 is fixedly connected to the pointer 204. The vial bubble 5 on the pointer 204 can be used to determine the flatness of the installation of the support 201 and the dial 205.

[0028] In the present invention, the diameter of the connecting bolt 102 is consistent with the bolt diameter of the wall support and the angle between the connecting bolt 102 and the inner clamping plate 101 is 90°, which prevents the connecting bolt 102 from being difficult to pass through the reserved hole, causing it to be unusable and wasting materials.

[0029] In this implementation scheme: First, an external wall embedded structure 1 is fabricated on site according to the number of bolts of the mechanical equipment wall support, connecting bolts 102 having the same number and position as the bolts of the mechanical equipment wall support are welded to the inner plywood 101, and corresponding holes are opened on the outer plywood 103 to ensure that the connecting bolts 102 can pass through, then the infrared positioning structure 2 is installed on the standard section of the mechanical equipment, the support 201 is more easily fixed to the standard section by the magnet 4, and then the angle of the wall-mounted rod is determined according to the manual of the mechanical equipment, and then the pointer 204 is moved, and the level bubble 5 on the pointer 204 can determine the flatness of the installation of the support 201 and the dial 205, the pointer 204 rotates on the connecting shaft 202 through the bearing 203, and the angle of the pointer 204 is observed through the dial 205 until it is consistent with the specified angle in the manual, and then the infrared is turned on. The transmitter 206, the infrared transmitter 206 emits a crosshair, and the hole position is marked on the outer wall according to the crosshair emitted to the outer wall and the hole is punched. After the hole is drilled, it is necessary to measure whether the position of the inner and outer template holes is horizontal to prevent the holes from tilting, which makes the outer wall pre-buried structure 1 difficult to install.

After the outer wall pre-buried structure 1 is fixed, the pouring of concrete can be started. After the pouring is completed, the positioning nut 104 is removed, and the inner plywood 101, the connecting bolt 102 and the outer plywood 103 can be removed from the outer wall to complete the opening of the reserved hole.
