Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a rotary locking type floor slab feeding port template. Background Art

[0002] The floor slab feed hole formwork is part of the formwork system used in the concrete floor pouring process. It is usually used to form the feed hole when the floor slab is poured for subsequent construction. This formwork usually has a special design and size to ensure that the position and size of the feed hole can be accurately reserved during the floor slab pouring process. The use of floor slab feed hole formwork helps to ensure the accuracy and efficiency of the feed hole construction.

[0003] The side panels of the traditional feed port template are usually flat plates, and the inner side of the feed port formed by pouring is flat. There is a problem that the bond between the new and old concrete is not strong enough when the feed port is sealed later; and during the pouring process, the template is easily affected by the pressure of the concrete and floats up and down or deflects and tilts, affecting the construction quality of the feed port. Utility Model Content

[0005] The technical solution of the utility model is: a rotary locking floor plate feed port template, the template is placed in the middle of the floor plate; the rotary locking floor plate feed port template comprises a feed port template and a rotary locking device;

[0006] The feed port template is in the shape of a square funnel as a whole, and the cross section of the side plate of the feed port template is in the shape of a broken line, the top outer edge is higher than the upper surface of the floor plate, and the bottom is aligned with the bottom surface of the floor plate; a crossbeam is arranged on the upper part of the feed port template, and a threaded collar is arranged in the middle part of the crossbeam;

[0007] The rotation locking device comprises a handle, a screw and a clamping rod; the screw is arranged vertically and matches with the threaded collar; the length of the screw is greater than the height of the feed port template; the handle is arranged at the top of the screw and the clamping rod is arranged at the bottom of the screw.

[0008] Preferably, a through hole is provided in the middle of the cross beam, and a threaded collar is coaxially fixed inside the through hole. The lead screw passes through the threaded collar in the middle of the cross beam, which can save space occupied by the rotation locking device.

[0009] Preferably, the threaded collar is arranged in the middle of the side of the beam. The threaded collar is arranged in the middle of the side of the beam, and there is no need to punch holes in the beam, which can increase the strength of the entire device.

[0010] Preferably, a sleeve is provided in the middle of the clamping rod, and the clamping rod is sleeved on the lower part of the lead screw through the sleeve. The through hole in the middle of the clamping rod is sleeved with the lead screw, so that the clamping rod can rotate relative to the lead screw, separating the "rotation" and "locking" parts of the rotation locking device, and preventing the two from interfering with each other and affecting the locking effect.

[0011] Preferably, the cross beams and the rotation locking devices are provided in two groups respectively, and are evenly arranged along the long side of the template. The cross beams and the rotation locking devices are provided in two groups, so that the template can be fixed more firmly.

[0012] Furthermore, the rotation locking device also includes a slotted nut and a split pin; a limit hole is set at the bottom of the lead screw, the slotted nut is sleeved on the bottom of the lead screw, and the split pin passes through the limit hole and is inserted into the slot on the bottom of the slotted nut. The slotted nut and the split pin cooperate with each other to prevent the clamping rod from sliding off the lead screw, and the entire device can be installed, replaced and disassembled.

[0013] (1) The rotating locking floor slab feed port template of the utility model has a side that is connected to the floor slab in a broken line shape. The side of the formed feed port can form a step. The concrete used to seal the feed port in the later stage can be staggered and combined with the side of the step, which is beneficial to improving the firmness of the feed port after sealing.

[0014] (2) The rotary locking device of the utility model locks the template by rotating the lead screw to pull the clamping rod, and the clamping rod can be rotated relative to the lead screw through the sliding sleeve when subjected to the upward pulling force, thereby preventing the clamping rod and the lead screw from rotating in conjunction with each other. The rotation and locking are separated, so the template can be fixed more firmly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1: See Figure 1-4, a rotary locking type floor plate 1 feed port template 2, the template is placed in the middle of the floor plate 1; the rotary locking type floor plate 1 feed port template 2 includes a feed port template 2 and a rotary locking device 3;

[0021] The feed port template 2 in this embodiment is in the shape of a square funnel as a whole, and the cross section of the side plate of the feed port template 2 is in the shape of a broken line, the outer edge of the top is higher than the upper surface of the floor plate 1, and the bottom is aligned with the bottom surface of the floor plate 1; it can increase the contact area between the side of the template and the floor plate 1, and the fit is tighter and not easy to fall off; the upper part of the feed port template 2 is provided with a crossbeam 21, and the middle part of the crossbeam 21 is provided with a threaded collar 22;

[0022] The rotation locking device 3 includes a handle 31, a screw 32 and a clamping rod 33; the screw 32 is vertically arranged and matches the threaded collar 22; the length of the screw 32 is greater than the height of the feed port template 2; the rotation locking device 3 is easy to lock and release; the handle 31 is arranged at the top of the screw 32, and the clamping rod 33 is arranged at the bottom of the screw 32.

[0023] The threaded collar 22 is arranged in the middle of the side of the beam 21. The threaded collar 22 is arranged in the middle of the side of the beam 21, and there is no need to punch holes in the beam 21, which can increase the strength of the entire device.

[0024] A sliding sleeve is provided in the middle of the clamping rod 33, through which the clamping rod 33 is sleeved on the lower part of the lead screw 32. The through hole in the middle of the clamping rod 33 is sleeved with the lead screw 32, so that the clamping rod 33 can rotate relative to the lead screw 32, separating the "rotation" and "locking" parts of the rotation locking device 3, and preventing the two from interfering with each other and affecting the locking effect.

[0025] There are two groups of cross beams 21 and rotation locking devices 3, respectively, which are evenly arranged along the long side of the template. Two groups of cross beams 21 and rotation locking devices 3 can fix the template more firmly.

[0026] The rotation locking device 3 also includes a slotted nut and a split pin; a limit hole is set at the bottom of the lead screw 32, the slotted nut is sleeved on the bottom of the lead screw 32, and the split pin passes through the limit hole and is inserted into the slot on the bottom of the slotted nut.
