Abstract
The utility model discloses a combined type protective device for a cave. The protective device comprises two trough plates and a cover plate, wherein the trough plates are symmetrically and fixedly arranged on the two sides of the cave; a chute is formed on the top of each of the trough plates along a length direction; an area of the cover plate is corresponding to the size of the cave; a slider corresponding to the chute is formed on the bottom of the cover plate. According to the combined type protective device for the cave disclosed by the utility model, the two sides of the cave are respectively fastened by using one trough plate, so that the trough plates and a base body of the cave are integrally connected; the chutes are formed on the trough plates and corresponding sliders are formed on the cover plate, therefore, if needed, the cave can be protected simply by pushing the cover plate along the chutes to completely cover the cave, vice versa, the cave can be used simply by pulling the cover plate out.
Description
Technical field
The utility model relates to the realm of building construction, refers in particular to the box-like opening protective device of a kind of steel tank template group.
Background technology
Construction site generally can be because of the reserved a lot of interim holes not of uniform size of a variety of causes, for security consideration need be carried out protective treatment to it.General safeguard procedures, as protective guard is set, take and tear complex procedures open and cost is high; As directly covered with sheet material, thereby it easily slides and causes security incident.
Utility model content
In view of the defect problem for hole protective treatment in above-mentioned prior art, the purpose of this utility model is, provides a kind of switching nimble, and cost is lower, can reasonably solve the combined type opening protective device of the defect of traditional protection method existence.
For this reason, the utility model provides a kind of combined type opening protective device, comprising:
Two frids, symmetry is fixedly arranged on the both sides at described hole, and described frid top offers a chute along its length;
One cover plate, the area of described cover plate is corresponding with the size at described hole, and the bottom of described cover plate is formed with the slide block corresponding with described chute.
Combined type opening protective device of the present utility model, both sides, hole are respectively with being fastened with a frid, and the matrix at frid and hole is connected as a single entity.Because offer chute on frid, on cover plate, be formed with corresponding slide block, so, in the time that hole need to be protected, cover plate is advanced and makes it cover hole completely along chute, vice versa, when hole need to utilize, cover plate can be pulled out.
The further improvement of the utility model combined type opening protective device is, described frid is steel tank.
The further improvement of the utility model combined type opening protective device is, described frid by bolton in the both sides at described hole.

Fig. 1 is the top view of combined type opening protective device of the present utility model.
Fig. 2 is the top exploded view of combined type opening protective device of the present utility model.
Fig. 3 is the lateral view of combined type opening protective device of the present utility model.
Fig. 4 is the schematic diagram after the cover plate of combined type opening protective device of the present utility model covers hole.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Coordinate referring to shown in Fig. 1 and Fig. 2, combined type opening protective device 1 of the present utility model, comprising:
Two frids 10, on the matrix 40 of the both sides that are fixed on described hole 30 by bolt 20 symmetries, the top of described frid 10 offers a chute 101 along its length; Preferably steel tank of described frid 10 can be also other objects with trench structure.
One cover plate 50, the area of described cover plate 50 is corresponding with the size at described hole 30, and shown in Fig. 3, the bottom of described cover plate 50 is formed with the slide block 501 corresponding with chute 101 on described frid 10.
Coordinate referring to shown in Fig. 1 and Fig. 4, when combined type opening protective device 1 of the present utility model uses, first on the matrix 40 of 30 both sides, hole, use respectively the fastening frid 10 of bolt 20, frid 10 and the matrix 40 at hole 30 are connected as a single entity.Because offer chute 101 on frid 10, on cover plate 50, be formed with corresponding slide block 501, so, in the time that hole 30 need to be protected, cover plate 50 is advanced and makes it cover hole 30 completely along chute 101, and vice versa, when hole 30 need to utilize, cover plate 50 can be pulled out.
The above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, not departing from the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
