Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a pre-embedded device for a pump pipe passing through a top plate hole. Background Art

[0002] At present, high-rise building construction uses vehicle-mounted pumps + pumping pipes to deliver to the operating surface. In order to facilitate the use of pump pipes, some temporary holes are often reserved on the roof of the building. The traditional roof reserved holes are processed into cone boxes by templates and installed in advance for pump pipe installation, or the concrete is poured near the pump pipe hole and the template is placed in a square to directly block the concrete. Both methods have the following shortcomings:

[0003] 1. During the concrete pouring process, the shaking of the pump pipe is easy to damage the embedded cone box, and the turnover rate is low;

[0004] 2. The cone box is usually taken out by knocking from bottom to top, which is difficult to operate;

[0005] 3. The templates are not placed neatly, the concrete is not tightly blocked, and the concrete is easy to flow below the reserved hole, resulting in concrete waste and the top plate thickness is easy to fail to meet the requirements;

[0006] 4. The shapes of the templates are not uniform, and the shape and appearance of the top plate are poor after forming. Utility Model Content

[0008] The technical solution is as follows: it comprises four steel plates which are detachably connected in sequence, two adjacent steel plates are connected by pins, each of the steel plates is in an isosceles trapezoidal shape, two sleeves are fixedly arranged on one of the side walls of the steel plate, and one sleeve is fixedly arranged on the other side wall, and the axes of the sleeves are respectively parallel to one of the hypotenuses of the steel plate;

[0009] When two adjacent steel plates are spliced, the three sleeves are coaxial and the pins are inserted into the sleeves.

[0010] Preferably, the side wall of the sleeve is flush with the side wall of the steel plate.

[0011] Preferably, two mounting seats are fixedly arranged on the plate body of each of the steel plates, and a support rod is rotatably arranged on one of the mounting seats;

[0012] A threaded hole is provided on the other mounting seat, the movable end of the support rod is threadedly connected to a screw rod, and a knob is fixedly arranged on the upper end of the screw rod;

[0013] When two steel plates are assembled, the screw rod is threadedly connected with the threaded hole on the mounting seat on the adjacent steel plate.

[0014] Preferably, a magnet block is fixedly arranged in the middle of the support rod.

[0015] The technical solution provided by the embodiment of the utility model has the following beneficial effects: the pump pipe hole is easy to pre-buried, and the removal is simple and quick. The hole size is uniform after the concrete is formed, ensuring the thickness of the concrete top plate and the appearance of the concrete hole after forming. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1

[0026] See also Figure 1 , Figure 2 The utility model provides a pre-embedded device for a pump pipe passing through a top plate hole, comprising four steel plates 1 which are sequentially detachably connected, two adjacent steel plates 1 are connected by pins 3, each steel plate 1 is in an isosceles trapezoidal shape, two sleeves 2 are fixedly arranged on one side wall of the steel plate 1, and one sleeve 2 is fixedly arranged on the other side wall, and the axis of the sleeve 2 is parallel to one of the hypotenuses of the steel plate 1 respectively;

[0027] When two adjacent steel plates 1 are spliced ​​together, the three sleeves 2 are coaxial and the pins 3 are inserted into the sleeves 2 .

[0028] The side wall of the sleeve 2 is flush with the side wall of the steel plate 1 .

[0029] The specific size of the steel plate 1 can be customized according to the actual needs of the site. In actual use, four identical steel plates 1 can be spliced ​​together to form a square opening, or a combination of two long steel plates 1 and two short steel plates 1 can be spliced ​​together to form a rectangular opening.

[0030] Furthermore, the steel plate 1 of the device is made of steel. In order to improve the performance of the steel plate 1, the steel plate 1 can be made of aluminum alloy, which has a smooth surface, is lighter in weight, and is easy to disassemble and carry.

[0031] When the utility model is used, the four steel plates 1 are spliced ​​end to end in sequence. When two adjacent steel plates 1 are spliced, the three sleeves 2 are coaxial, and the pins 3 are inserted into the sleeves 2. After the four steel plates are assembled, the device as a whole presents an inverted trapezoidal structure with a small bottom and a large top. The device is then placed on the template and fixed. In order to facilitate the removal of the steel plate 1, a release agent can be applied to the outer side of the steel plate 1 before concrete pouring. After the top plate concrete is poured, the pins 3 are first removed, and the steel plates 1 are removed in sequence. After the concrete is formed, the hole size is unified to ensure the thickness of the concrete top plate and the appearance of the concrete hole after forming.

[0032] Example 2

[0033] Based on Example 1, see Figure 3 , Figure 4 Two mounting seats 4 are fixedly arranged on the plate body of each steel plate 1, and a support rod 5 is rotatably arranged on one of the mounting seats 4;

[0034] A threaded hole is provided on another mounting seat 4, the movable end of the support rod 5 is threadedly connected to the screw rod, and a knob 6 is fixedly provided on the upper end of the screw rod;

[0035] When two steel plates 1 are assembled, the screw rod is threadedly connected with the threaded hole on the mounting seat 4 on the adjacent steel plates 1 .

[0036] After the steel plates 1 are spliced, in order to ensure the squareness of the reserved hole, two adjacent steel plates 1 are fixedly connected by support rods 5. The screw rods are simply threadedly connected to the threaded holes on the mounting seats 4 on the adjacent steel plates 1 to obtain a relatively square reserved hole.

[0037] A magnet block 7 is fixedly arranged in the middle of the support rod 5. The magnet block 7 enables the support rod 5 to be adsorbed on the steel plate 1 when not in use, so as to facilitate the transportation and storage of the device.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
