Description

Technical Field

[0001] This utility model relates to the field of prefabricated composite slab support technology, and more specifically, to a prefabricated composite slab support structure. Background Technology

[0002] Composite slabs can be widely used in various building construction projects such as hotels, office buildings, schools, residences, hospitals, warehouses, parking lots, and multi-story industrial plants.

[0003] Currently, support structures are required for the installation of prefabricated composite slabs. However, common support structures are time-consuming to set up and have a small support area. For example, CN206752844U discloses a support structure for prefabricated composite slabs, which includes a main beam. The main beam is made of steel frame cast in concrete. Threaded sleeves are pre-embedded in the main beam. An angle steel is provided outside the threaded sleeves. A support square tube is mounted on the angle steel to support the prefabricated composite floor slab.

[0004] As can be seen from the above-mentioned publicly available scheme, the supporting square tube is supported by angle steel, and the angle steel is fixed by fastening bolts. The installation is time-consuming and laborious, which reduces the work efficiency. At the same time, the support strength is insufficient due to the pressure of the fastening bolts. Furthermore, this support structure results in a small support area between the end of the precast composite floor slab and the beam, which reduces the support safety. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a prefabricated composite slab support structure. This prefabricated composite slab support structure can quickly assemble the support pipe with the precast beam through the setting of embedded parts, docking blocks and fixing parts, and increases the support strength and improves the work efficiency. Furthermore, the setting of limiting blocks, clamping grooves and support plates can increase the contact area between the precast composite slab body and the beam body, thereby increasing the support area and ensuring the support safety of the precast composite slab body.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A prefabricated composite slab support structure includes a support structure body. A precast beam is detachably connected to one end of the support structure body. A steel beam is fixedly installed on the surface of the precast beam, and a fastener is fixedly installed on the surface of the steel beam. The support structure body includes a support pipe. A reinforcing component is fixedly welded to one end of the support pipe. One end of the reinforcing component is movably connected to the side of the precast beam. An embedded part is fixedly connected to the side of the precast beam, and the surface of the embedded part is movably connected to the surface of the steel beam. A precast composite slab body is movably connected to the surfaces of the steel beam and the support pipe. This prefabricated composite slab support structure, through the embedded parts, connecting blocks, and fixing parts, allows for rapid assembly of the support pipe and the precast beam, increasing support strength and improving work efficiency. Furthermore, the limiting blocks, clamping grooves, and support plates increase the contact area between the precast composite slab body and the beam, thereby increasing the support area and ensuring the support safety of the precast composite slab body.

[0008] Furthermore, the reinforcing component includes a fixing part, the surface of which is movably connected to the inner wall of the support tube, and a limiting plate is fixedly connected to one side of the fixing part. The surface of the limiting plate is fixedly welded to the end face of the support tube. The fixing part can increase the connection strength and support strength of one end of the support tube.

[0009] Furthermore, a limiting block is fixedly connected to the side of the limiting plate, and the limiting block and the limiting plate surround a clamping groove. A support plate is movably connected to the inner wall of the clamping groove. An anti-slip groove is opened at the bottom of the support plate. The surface of the support plate contacts and presses against the bottom of the precast composite slab body, which can increase the support area at one end of the precast composite slab body.

[0010] Furthermore, a plug-in groove is provided on one side of the embedded part, and a plug-in block is fixedly connected to the inner wall of the plug-in groove. The cross-sectional shape of the plug-in block is rectangular. The plug-in groove facilitates the plug-in and positioning with the docking block, thereby improving assembly efficiency.

[0011] Furthermore, a docking block is fixedly connected to one end of the limiting block, the surface of the docking block is movably connected to the inner wall of the insertion groove, and a docking groove is opened at one end of the docking block, which facilitates insertion and positioning with the insertion block.

[0012] Furthermore, the cross-sectional shape of the docking groove is rectangular, and the inner wall of the docking groove is movably connected to the surface of the plug-in block. Inserting the plug-in block into the docking groove can increase the strength of the connection.

[0013] Furthermore, the surface of the precast beam is pre-set with insertion holes, and the inner wall of the insertion holes is movably connected to the surface of the fastener, which can limit the installation position of the precast beam.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can quickly assemble the support pipe with the precast beam by setting the embedded parts, docking blocks and fixing parts, and it also increases the support strength and improves the work efficiency.

[0016] (2) This scheme can increase the contact area between the precast composite slab body and the beam body by setting limit blocks, clamping grooves and support plates, thereby increasing the support area and ensuring the support safety of the precast composite slab body.

The fastener 21 is U-shaped and can quickly position the precast beam 3 installed in the steel beam 2. After positioning, the fastener 21 is welded to the steel beam 2. The support structure body 1 includes a support pipe 4, which is a square hollow pipe. A reinforcing component 5 is fixedly welded to one end of the support pipe 4, and an axially movable reinforcing component 5 is provided at the other end of the support pipe 4 to facilitate the horizontal installation of the support pipe 4 between two precast beams 3. The reinforcing component 5 includes a fixing part 51, the surface of which is movable to the inner wall of the support pipe 4. The fixed part 51 is fixedly connected to a limiting plate 52 on one side. The surface of the limiting plate 52 is fixedly welded to the end face of the support pipe 4. The fixed part 51 can increase the connection strength and support strength of one end of the support pipe 4. The reinforcing component 5 can increase the connection efficiency and support strength between the support pipe 4 and the precast beam 3. One end of the reinforcing component 5 is movably connected to the side of the precast beam 3. The side of the precast beam 3 is fixedly connected to an embedded part 32. The embedded part 32 is made of metal. An insertion groove 33 is provided on one side of the embedded part 32. An insertion block 34 is fixedly connected to the inner wall of the insertion groove 33. The cross-sectional shape of the insertion block 34 is rectangular. The insertion groove 33 facilitates insertion and positioning with the docking block 54, improving assembly efficiency. The surface of the embedded part 32 is movably connected to the surface of the steel beam 2. The surfaces of the steel beam 2 and the support pipe 4 are movably connected to the precast composite plate body 7.

[0027] A limiting block 53 is fixedly connected to the side of the limiting plate 52. The limiting block 53 and the limiting plate 52 enclose a clamping groove 56. A support plate 6 is movably connected to the inner wall of the clamping groove 56. An anti-slip groove 61 is opened at the bottom of the support plate 6. The surface of the support plate 6 contacts and presses against the bottom of the precast composite slab body 7, which can increase the support area at one end of the precast composite slab body 7. A docking block 54 is fixedly connected to one end of the limiting block 53. The surface of the docking block 54 is movably connected to the inner wall of the insertion groove 33.
