Description

Technical Field

[0001] The present application relates to the technical field of construction engineering equipment, and specifically discloses a prefabricated cover plate fixture for an underground integrated pipe gallery. Background Art

[0002] In the underground comprehensive pipe gallery project, each fire compartment is equipped with ventilation holes and equipment rooms. According to the design requirements, prefabricated cover plates need to be placed in the ventilation holes. The prefabricated cover plates are cast with C40 concrete, and the production cost is relatively high, and a large number is required.

[0003] At present, there are two main ways to lift the traditional precast concrete cover plates: one is to lift by binding straps. The main disadvantages of this method are: binding straps will take up a lot of time and the lifting speed is slow; the other is to pre-embed the pull ring lifting point. This method requires pre-embedded pull rings, which increases the difficulty of manufacturing the cover plate. At the same time, the pull rings are only used during lifting. A large number of pre-embedded pull rings in the precast cover plates will also cause material waste.

[0004] Therefore, in view of this, the inventor provides a prefabricated cover plate clamp for an underground integrated pipeline corridor to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the problems that the existing prefabricated cover plate clamp cannot be applied to cover plates of different sizes, is inconvenient to use and has unstable clamping.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a prefabricated cover plate clamp for an underground comprehensive pipe gallery, including a clamp body and a lifting ear fixedly connected to the top of the clamp body, a plurality of sliding grooves are provided at both ends of the clamp body, and a fixing seat with a threaded hole is slidably connected in the sliding groove at one end of the clamp body, and a fixing rod with an external thread at the end is threadedly connected to the fixing seat for fixing the cover plate, the bottom of the fixing rod extends out of the sliding groove at the other end of the clamp body and is detachably connected to a first fixing part, the side wall of the clamp body is provided with a through opening for the cover plate to pass through, and the side wall of the clamp body is also rotatably connected with a baffle for blocking the through opening after the cover plate is placed into the through opening to prevent the cover plate from slipping off, and the clamp body is also provided with a second fixing part for fixing the position of the fixing seat.

[0007] Furthermore, the clamp body includes a vertical plate and horizontal plates fixedly connected to both ends of the vertical plate and parallel to each other, and the horizontal plates are both provided with sliding grooves.

[0008] Furthermore, the second fixing member includes a fixing ear fixedly connected to one side of the fixing seat, a fixing hole provided on the fixing ear, a fixing groove provided on the transverse plate and facing the fixing hole, and a fixing column which can extend into the fixing hole and abut against the fixing groove.

[0009] Furthermore, the shape of the lifting ear is circular.

[0010] Furthermore, the first fixing member is a fixing nut.

[0011] Furthermore, the side wall of the vertical plate is provided with a threaded hole, the baffle is also provided with a threaded hole, and the vertical plate is provided with bolts that can extend into the threaded hole and fix the baffle on the vertical plate.

[0012] Furthermore, the fixing rod is a cylindrical blocking column with external threads at both ends, and the middle section of the circular blocking column is a smooth curved surface.

[0013] The principle and effect of this scheme are:

[0014] 1. Compared with the prior art, the utility model can directly hook the hook of the lifting tool through the provided lifting ear, without the need for bundling or pre-embedded lifting rings on the cover plate, thus speeding up the lifting speed. Through the provided slide groove and fixed seat, the sliding fixed seat makes the screw rod abut against the side wall of the cover plate, so that the fixed position can be adjusted according to the cover plates of different sizes. The friction between the internal thread and the spiral pattern of the screw rod can enhance the fixing effect of the cover plate. Through the provided through-hole, it is convenient to place the four corners of the cover plate on the cover plate clamp. The rotating baffle blocks the through-hole to prevent the cover plate from slipping from the through-hole during the lifting process, thereby increasing the safety during the lifting process. The device can be used to lift covers of different sizes, which can be used sustainably, reduce costs, and increase the practicality of the clamp.

[0015] 2. The utility model fixes the screw rod multiple times by cooperating with the second fixing member and the first fixing member. The friction of the thread and the fixing effect of the fixing nut make the threaded rod clamp the cover plate more firmly, thereby enhancing the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS
