Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance and reinforcement, and more specifically, to a base for fixing a concrete structure drilling device. Background Art

[0002] After the construction of building structures, such as bridges and houses, necessary repairs and reinforcements are required, and other facilities are added to improve or enhance the existing condition of the building structure to keep it in good functional condition. Most of the repair and reinforcement operations of building structures require the use of drilling and rebar planting technology to repair and reinforce the damaged parts or add other facilities to the original structure.

[0003] During the construction process, drilling is a key step in rebar planting. Usually, a core drilling machine is used for drilling. During construction, the location of the rebar to be planted is first measured and laid out, and then the worker uses a handheld core drilling machine to perform drilling. The following problems are prone to occur when using a manually controlled core drilling machine for drilling: (1) When drilling with a manually controlled core drilling machine, it is easy for the drilling hole to be offset or the hole to be non-vertical. The accuracy and verticality of the drilling position cannot be guaranteed, which will ultimately affect the construction quality and pose a certain risk to the safety of the structure. (2) Manually controlled core drilling machines consume a lot of physical strength from the workers, resulting in low construction efficiency and affecting the progress of the project. Utility Model Content

[0004] Another object of the utility model is to provide a base for fixing a concrete structure drilling device, which fixes the position of the drilling machine during the drilling operation, thereby ensuring the accuracy of the drilling position and the verticality of the drilling.

[0006] A panel, on which a positioning frame is provided, and the panel is vertically erected on the top of the concrete structure to be drilled through the positioning frame;

[0007] A plurality of positioning grooves are arranged at intervals along the height direction of the panel, and any positioning groove is opened on the panel along the length direction of the panel. The mast of the drilling rig is detachably arranged in the positioning groove, and the mast of the drilling rig is arranged perpendicular to the panel.

[0008] Preferably, the positioning frame comprises:

[0009] Two cross bars are arranged at intervals along the length direction of the panel, one cross bar is vertically fixed on the back of the panel, and the bottom surface of one cross bar is vertically fixed with a first leg;

[0010] Two second legs are arranged at intervals along the length direction of the panel, and any second leg is vertically fixed at the bottom of the panel; the panel is clamped on the top of the concrete structure to be drilled through the first leg and the second leg.

[0011] Preferably, a plurality of adjustment components are provided on any of the second legs, which are arranged at intervals along the height direction of the second leg, and any of the adjustment components includes a bolt hole opened on the second leg and an adjustment bolt arranged on the bolt hole, and the adjustment bolt is arranged perpendicular to the second leg.

[0012] Preferably, a shock-absorbing sleeve is sleeved on one end of any adjusting bolt close to the first leg.

[0013] Preferably, a connecting rod is provided between the two cross bars; and a stiffening plate is welded between the cross bar and the panel, and between the cross bar and the first leg.

[0014] Preferably, rubber pads are adhered to the contact surfaces of the positioning frame and the panel with the concrete structure to be drilled.

[0015] Preferably, the panel and the two second legs are integrally formed.

[0028] A panel 1, on which a positioning frame is provided, and the panel 1 is vertically erected on the top of the concrete structure 6 to be drilled through the positioning frame;

[0029] A plurality of positioning grooves 101 are arranged at intervals along the height direction of the panel 1. Any positioning groove 101 is opened on the panel 1 along the length direction of the panel 1. The mast of the drilling rig is detachably arranged in the positioning groove 101. The mast of the drilling rig is arranged perpendicular to the panel 1.

[0030] In the above technical solution, if Figure 1 , Figure 3As shown, the base is composed of a rectangular panel 1 and a positioning frame, the panel 1 is mounted on the concrete structure 6 to be drilled through the positioning frame, and the lower part of the panel 1 is the area 601 to be drilled of the concrete structure 6; a positioning groove 101 is provided on the panel 1, and the positioning groove 101 is used to connect with the mast of the core drilling machine, so that the core drilling machine is vertically installed on the panel 1, and the drill bit of the drilling machine is directly above the area 601 to be drilled; because the mast of the drilling machine is arranged parallel to the drill bit at an interval, when installing the mast, it is only necessary to make the installation position of the mast directly above the hole to be drilled, start the drilling machine, and the drill bit will be at the drilling layout point, along the vertical surface The drilling rig is drilled in the direction of the panel 1, thereby ensuring the accuracy of the drilling position and the verticality of the drilling hole; a plurality of positioning grooves 101 are provided along the height direction of the panel 1, so that drilling operations can be carried out on holes at different heights, and for multiple holes located in the same vertical direction, there is no need for multiple measurements and layouts, which can improve construction efficiency; since the mast of the drilling rig is arranged in the positioning groove 101, most of the weight of the drilling rig can be borne by the base, and the workers only need to hold the drilling rig to carry out drilling operations, which reduces the workers' work intensity, improves construction efficiency, and ensures construction progress; the mast of the drilling rig is detachably installed in the positioning groove 101 by bolts.

[0031] In another technical solution, the positioning frame includes:

[0032] Two cross bars 2 are arranged at intervals along the length direction of the panel 1, and any cross bar 2 is vertically fixed on the back of the panel 1, and a first leg 201 is vertically fixed on the bottom surface of any cross bar 2;

[0033] Two second legs 102 are spaced apart along the length direction of the panel 1, and any second leg 102 is vertically fixed at the bottom of the panel 1; the panel 1 is clamped on the top of the concrete structure 6 to be drilled through the first leg 201 and the second leg 102.

[0034] In the present technical solution, the back side of the panel 1 is the side away from the area to be drilled 601, and the panel 1 is clamped on the concrete structure 6 by the first leg 201 and the second leg 102. The overall device has a simple structure, low manufacturing cost, easy installation, and is reusable. In order to further improve the convenience of manufacturing and installation, as well as the integrity of the base structure, the cross bar 2, the panel 1, the first leg 201 and the second leg 102 are connected by welding.

[0035] In another technical solution, a plurality of adjustment components are provided on any of the second legs 102, which are arranged at intervals along the height direction of the second leg 102, and any of the adjustment components includes a bolt hole 301 opened on the second leg 102 and an adjustment bolt 3 arranged on the bolt hole 301, and the adjustment bolt 3 is arranged perpendicular to the second leg 102.
