Description

Technical Field

[0001] This utility model relates to the field of construction technology of composite slabs in buildings, and in particular to a device for reducing grout leakage in composite slabs during building construction. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs offer good overall integrity, with smooth upper and lower surfaces, facilitating finishing and making them suitable for high-rise buildings and large-span buildings requiring high overall rigidity. During construction, additional slabs or scaffolding are installed underneath for sealing or reinforcement, and secured with reinforcing devices to prevent grout leakage. Traditional installations have numerous components and a simple support principle, making pre-embedding and assembly cumbersome. Misalignment during support is prone to occur and difficult to correct, affecting the final construction result. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a device for reducing grout leakage in composite slab construction.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A device for reducing grout leakage in composite slabs during building construction includes a template positioned below the gap between adjacent composite slabs, a wooden joist positioned below the template, a top support positioned below the wooden joist, and a locking rod mechanism positioned between the top support and the wooden joist. The locking rod mechanism includes a reinforcing screw, a locking sleeve, an extension screw, a locking arm, and a fixing nut. The locking sleeve and the reinforcing screw are connected by threads, and the locking sleeve and the extension screw are in a limiting fit. The extension screw passes through the locking arm and is locked by the fixing nut, thereby creating a tightening clamping tendency between the locking sleeve and the locking arm.

[0006] Furthermore, the locking screw sleeve has a through-hole at its center, the hole wall has an internal thread, and a stop part is provided in the hole near the lower opening.

[0007] Furthermore, the extended screw has a flange at its top, and the extended screw passes through the connecting hole and is stopped and limited by the flange and the stop portion.

[0008] Furthermore, the reinforcing screw and the locking sleeve are fixed by a threaded connection.

[0009] Furthermore, the upper top surface of the locking screw arm is provided with a smooth part, a close contact part and a hooking part in sequence from the middle to both sides, and the height of the smooth part, the close contact part and the hooking part increases in sequence.

[0010] Furthermore, the dense contact portion has a continuously undulating waveform structure, and the hook portion has a single hook-shaped structure.

[0011] Furthermore, the height of the upper bottom surface of the fixing nut gradually decreases from the middle to both sides.

[0012] Furthermore, the reinforcing screw adopts a T-shaped structure.

[0013] The beneficial effects of this utility model are:

[0014] 1) The grout leakage reduction device for composite slabs provided by this utility model has a simple and ingenious structure, few parts, and is easy to disassemble and adjust, and is practical and economical.

[0015] 2) This utility model provides a top support under the template and a locking rod mechanism above the template for tightening, ensuring the tight fit between the template and the composite plate, thereby reducing grout leakage.

[0016] 3) The locking rod mechanism of this utility model can be coarsely and finely adjusted according to the usage requirements, which improves the convenience of installation and use. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1-5As shown, a device for reducing grout leakage in composite slabs during building construction includes two composite slabs 13 (left and right), a template 14, a wooden joist 15, a top support 16, and a locking rod mechanism. A pouring gap is provided between the two composite slabs 13, and templates 14 are provided below and on both sides of the pouring gap. Since the fixing of the templates on both sides is not involved in this utility model, it is ignored.

[0025] The template 14 is provided with a wooden joist 15 and a top support 16 below it. A locking rod mechanism is provided between the wooden joist 15 and the top support 16. The top support 16 is used for lower support, and the locking rod mechanism is used for upper locking. The upper and lower parts work together to reduce grout leakage at the pouring joint.

[0026] The locking rod mechanism includes a reinforcing screw 1, a locking sleeve 2, an extension screw 3, a locking screw arm 4, and a fixing nut 5 arranged in sequence.

[0027] In use, first, the extended screw 3 is passed through the locking sleeve 2 to form a union structure. Union structures are a common method for pipe fitting connections, and will not be elaborated upon or limited here. Then, the locking sleeve 2 is connected to the reinforcing screw 1; at this point, it is not necessary to over-insert the reinforcing screw 1 into the locking sleeve 2. Next, the extended screw 3 is passed through the pre-drilled hole, and the locking arm 4 and fixing nut 5 are fitted onto the component below the composite plate to tighten the clamp. It should be noted that the fixing nut 5 is rotated for coarse tightening, and fine tightening can be performed using the reinforcing screw 1 when necessary. The special feature is that the coarse adjustment meets the initial installation requirements, while the fine adjustment is mostly used for potential loosening or deviations later. Furthermore, considering the structural characteristics of this embodiment, further tightening the clamp under deviation conditions does not affect the construction effect.

[0028] The locking sleeve 2 has a through connecting hole 6. The wall of the connecting hole 6 has an internal thread and a retaining part 7 near the opening. One end of the extension screw 3 has a flange 8. The extension screw 3 passes through the connecting hole 6 and is stopped and limited by the flange 8 and the retaining part 7. This is a feature of an almost swivel joint structure. First, it is coarsely adjusted so that the flange 8 touches the bottom and is stopped and limited. Then, it is finely adjusted by the reinforcing screw 1 so that the reinforcing screw 1 is slightly inserted into the locking sleeve 2.

[0029] The reinforcing screw 1 and the locking sleeve 2 are fixed by a threaded connection. The locking screw arm 4 has an opening 9 for the extension screw 3 to pass through, and the end of the locking screw arm 4 facing away from the flange 8 is threadedly connected to the fixing nut 5. The locking sleeve 2 and the locking screw arm 4 form a tightening clamping tendency through the extension screw 3. The locking screw arm 4 is equivalent to a sliding pad, mainly tightened by the fixing nut 5. This method is convenient to operate and also leaves operating space for a large tool to rotate the fixing nut 5.

[0030] Both the reinforcing screw 1 and the locking screw arm 4 have a T-shaped structure. The upper surface of the locking screw arm 4 has a smooth section 10, a tight contact section 11, and a hooking section 12, arranged sequentially from the center to both sides, with the heights of the smooth section 10, tight contact section 11, and hooking section 12 increasing sequentially. The reinforcing screw 1 can be operated manually or finely adjusted using readily available tools. The hooking section 12 is used to maintain positioning and prevent slippage during initial installation. The tight contact section 11 ensures a tight fit even when the hooking section 12 is not fully functional or has failed. The smooth section 10 retains the basic functionality of a traditional device even when the other two fail. Furthermore, the smooth section 10 is less prone to damage and failure than the tight contact section 11. With proper use, the tight contact section 11 and hooking section 12 can function simultaneously, while the smooth section 10 strengthens the structure rather than providing clamping support.

[0031] The contact portion 11 has a continuously undulating wave-like structure, and the hook portion 12 has a single hook-shaped structure. This is one embodiment and not the only limitation. The height of the upper bottom surface of the fixing nut 5 gradually decreases from the middle to both sides, which is in line with the design requirements for structural strength. It should be noted that the requirements for the hook portion 12 are minimal. The hook portion 12 mainly prevents deviation rather than clamping and supporting, and avoids excessive structural strength at the hook portion 12 affecting the use of other parts.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the basic principles, main features, and advantages of this utility model have been shown and described above, which should be understood by those skilled in the art.
