Abstract
The utility model discloses a building surveying lead observation point protection device comprising a lead observation point mark and further comprising concrete fixing the lead observation point mark, and a brick forming mold for hardening the concrete to be in a specified shape, and a cover board is arranged on the top of the brick forming mold. A lead observation point is arranged on the concrete mortar, the periphery of the lead observation point is retained and fixed through the brick forming mold, and therefore the lead observation point is not prone to displacement under the action of certain mechanical force; meanwhile, the cover board is arranged on the lead observation point and protects the lead observation point, the lead observation point is not prone to being damaged, and the lead observation point can be protected well.
Description
Technical field
The utility model is the fixing measuring point protection device that draws that a kind of construction account is used, and is for protection construction account is with fixing pilot measurement point damaged design not, belongs to the realm of building construction.
Background technology
The fixing pilot measurement point that in engineering construction, construction account is used is the foundation of construction survey, and therefore, construction account is very important with the protection of fixing pilot measurement point apparatus.Existing situation is that pilot measurement point is made of timber, and by timber nail, on ground, surrounding adds nail 4-6 root timber, is entangled in surrounding implements protection with entanglement; Do like this, under rain drop erosion, may cause timber displacement, also may under certain mechanical force, be subjected to displacement, even destroyed.
Summary of the invention
For problem above, the utility model provides a kind of construction account to draw measuring point protection device, can protect pilot measurement point unshift, is difficult for destroyed.
Concrete solution is: a kind of construction account draws measuring point protection device, comprises pilot measurement dot mark, also comprises the concrete of fixing pilot measurement dot mark, by the formalize brick loose tool of shape of concrete hardening established practice, at described brick loose tool top, is provided with cover plate.
As preferably, described pilot measurement dot mark is made by the elongated metallic rod that is difficult for corrosion and wearing and tearing.
As preferably, described cover plate locks it in brick loose tool top with lockset.
As preferably, described brick loose tool is formed by masonry of cement mortar, and its end face exceeds pilot measurement dot mark end face 30-50mm.
Beneficial effect: by pilot measurement point is arranged on concrete mortar; around with brick loose tool enclosing, fix; thereby make pilot measurement point be difficult for being subjected to displacement under certain mechanical force; and; on pilot measurement point, be provided with cover plate; pilot measurement point protection is got up, make pilot measurement point not be subject to destruction, thereby protect well pilot measurement point.

Fig. 3 is pilot measurement point protection device cover plate schematic diagram;
In figure, 1-pilot measurement dot mark; 2-cover plate; 21-cover plate frame; 221-panel frame; 222-plate face; 23-hinge; 3-concrete; 4-brick loose tool.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Certain engineering is protected with fixing pilot measurement point apparatus construction account, and specific practice is as shown in Figure 1, draws measuring point protection device, includes: pilot measurement dot mark 1, cover plate 2, concrete 3, brick loose tool 4; With the fixing pilot measurement dot mark of concrete, with brick loose tool, make in the position of regulation, to become the shape of regulation after concrete hardening, at brick loose tool top, cover plate is set, and cover plate is locked.
The first excavation shape hole degree of depth reaches 1.25 meters, and 600 millimeters of every length of sides, build brick loose tool by laying bricks or stones to ground, and building materials is fired common brick and M5 sand-cement slurry, and building by laying bricks or stones is highly 1.25 meters;
Brick loose tool 4 is built by laying bricks or stones in two steps and is carried out, and builds by laying bricks or stones and highly reaches before 750 millimeters, while build by laying bricks or stones, bankets, and inside and outsidely all tamps; Then carry out the installation of pilot measurement dot mark;
The pilot measurement dot mark 1 of fixing pilot measurement point apparatus, is to be 1 meter by length, and diameter is that the reinforcing bar of 20 millimeters is made, and antirust processing is done in end, is difficult for corrosion and wearing and tearing.
Adjust horizontal level and the vertical height of pilot measurement dot mark, then build ground by laying bricks or stones, horizontal level and the crown level of the pilot measurement of inspecting for acceptance dot mark 1, fix with C20 concreting after correcting.
The concrete of described fixing pilot measurement point apparatus be the position of pilot measurement point and top mark are high determine after, fixedly pilot measurement point is built, concrete end face must be smooth, smooth, and must not hide pilot measurement dot mark, must make pilot measurement dot mark expose concrete surface.
At brick loose tool top, cover plate frame 21 is set again, with 45 bugle steel, is welded into the length of side and is the rectangle frame of 540 millimeters, the steel tie of welding and brick loose tool 4 drawknots in rectangle frame, 6 millimeters of tension rib diameters, 120 millimeters of length, end is provided with crotch; And cover plate frame 21 is embedded in the mortar of brick loose tool top, by top of concrete Troweling press finishing, carry out maintenance, after concrete hardening, lock.
Described cover panels comprises panel frame 221 and plate face 222, and panel frame 221 use angle steel are made, and plate face is made of 3 millimeters of steel plates, between panel frame 221 and plate face 222, adopts and is welded to connect; Between panel 222 and cover plate frame 221, by hinge 23, be connected the opposite installation lockset of hinge on one side.
Described brick loose tool is firm with building block and masonry of cement mortar, can play a protective role to pilot measurement dot mark, and end face must exceed the end face 30-50 millimeter of pilot measurement dot mark.
Claims (4)
