Abstract
The utility model relates to a reserve interim guard plate in entrance to a cave, the rectangular substrate who arranges side by side including a plurality of is equipped with a left lug respectively at every rectangular substrate's left side both ends, is equipped with the through -hole on left lug, is equipped with right lug corresponding to the position of left lug respectively at every rectangular substrate's right side both ends, be equipped with on right lug with the relative through -hole of diameter of hole same position of left lug, be equipped with a plurality of parallel arrangement's installation punch combination on every rectangular substrate's face, the installation punch combination includes that a plurality of interval sets up the mounting hole that forms a line. The utility model has the advantages of reasonable design, can assemble rectangular substrate at will in order satisfying the not requirement at the equidimension entrance to a cave, the flexible operation, work efficiency is high, can not lead to the fact the waste, when the transportation storage, can dismantle the storage transportation with each rectangular substrate, and also the accessible bolt that will connect left lug and right lug is unscrewed, makes each rectangular substrate folding the packing up each other in the guard plate to reduce the convenient transportation in shared space.
Description
Technical field:
The utility model relates to a kind of reserved opening provisional protection plate.
Background technology:
In building operations, because the needs of engineering and operation are usually provided with reserved opening in the layer structures such as floor, roofing and platform.In order to prevent people and object from falling from reserved opening, needing to place provisional protection plate at reserved opening place, provisional protection plate being covered on reserved opening, prevents people and object from falling from reserved opening.Because reserved opening type and field of employment different, the size of reserved opening is also different, and current provisional protection plate size is uncontrollable, the provisional protection plate being applicable to little hole more like this can not be applicable to larger hole, larger provisional protection plate causes waste for covering little hole, when practice of construction, need to add up according to hole size the protected apron selecting to vary in size in advance, affect job schedule.
Utility model content:
The utility model, in order to make up the deficiencies in the prior art, provides a kind of reserved opening provisional protection plate, its reasonable in design, the requirement that reserved opening varies in size can be met, there will not be the problem of waste, improve operating efficiency, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of reserved opening provisional protection plate, comprise the rectangular substrate that several are arranged side by side, a left lug is respectively equipped with at the two ends, left side of each rectangular substrate, left lug is provided with the through hole vertically arranged, the position corresponding respectively to left lug at the two ends, right side of each rectangular substrate is provided with right lug, right lug is provided with the through hole relative with the through-hole diameter same position of left lug, the plate face of each rectangular substrate is provided with several installing hole groups be arranged in parallel along the length direction of rectangular substrate, installing hole group comprises several intervals and arranges the installing hole formed a line, bolt is passed through between two adjacent rectangular substrate, the left lug of one rectangular substrate is connected with the right lug of another rectangular substrate by nut.
The utility model adopts such scheme, reasonable in design, can arbitrarily assemble rectangular substrate with the requirement at satisfied different size hole according to the size at hole, flexible operation, operating efficiency is high, waste can not be caused, when transporting storage, each rectangular substrate can be disassembled and storing transport, also by the bolt connecting left lug and right lug is unscrewed, make that each rectangular substrate in protected apron is mutually folding packs up, with reduce the convenient transport that takes up space.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is the utility model use.
Fig. 3 is the structural representation after the utility model folding storage.
In figure, 1, rectangular substrate, 2, left lug, 3, right lug, 4, installing hole.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-3, a kind of reserved opening provisional protection plate, comprise the rectangular substrate 1 that several are arranged side by side, a left lug 2 is respectively equipped with at the two ends, left side of each rectangular substrate 1, left lug 2 is provided with the through hole vertically arranged, the position corresponding respectively to left lug 2 at the two ends, right side of each rectangular substrate 1 is provided with right lug 3, right lug 3 is provided with the through hole relative with the through-hole diameter same position of left lug 2, the plate face of each rectangular substrate 1 is provided with several installing hole groups be arranged in parallel along the length direction of rectangular substrate 1, installing hole group comprises several intervals and arranges the installing hole 4 formed a line, bolt is passed through between two adjacent rectangular substrate 1, the left lug 2 of one rectangular substrate 1 is connected with the right lug 3 of another rectangular substrate 1 by nut.
During use, according to the size at hole, select the number of rectangular substrate 1 to adjust the width of protected apron, after width adjustment is good, if need the length increasing protected apron, two pieces of protected aprons can be assembled into a protected apron by bolt by another consistent for the length be spliced into by several rectangular substrate 1 protected apron, during assembling, according to the length of required increase, adjust two protected aprons coincide part size, the installing hole 4 of two protected aprons of intersection is overlapped, then two pieces of protected aprons are assembled into a protected apron by erection bolt, to reach the object increasing protected apron length.To the provisional protection plate of length and width be adjusted, cover on reserved opening, and prevent people and object from falling from reserved opening.When provisional protection plate use to pack up time, each rectangular substrate 1 can be disassembled and store transport, also by the bolt connecting left lug 2 and right lug 3 is unscrewed, each rectangular substrate 1 in protected apron is folded mutually pack up, take up space to reduce convenient transport, re-assemblies rectangular substrate 1 when avoiding use next time simultaneously.
Adopt the utility model protected apron, can arbitrarily assemble rectangular substrate 1 with the requirement at satisfied different size hole according to the size at hole, flexible operation, operating efficiency is high, can not cause waste.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
