Description

Technical Field

[0001] This utility model relates to the field of precast floor slab technology, specifically to an assembly structure for precast floor slabs. Background Technology

[0002] Precast floor slabs are concrete floor components that are prefabricated in a factory. They can be transported directly to the construction site for installation, greatly shortening the construction cycle. Precast floor slabs have a wide range of applications, including but not limited to cement slabs covering ditches next to roads and cement slabs used as insulation layers on roofs.

[0003] Precast floor slabs, as an early and widely used building component, have the advantages of fast construction speed and high cost-effectiveness. However, they are prone to large deviations and poor load-bearing capacity during installation. Furthermore, some precast floor slabs leave gaps after installation and fixing, which can lead to water seepage in the building. In addition, the gaps also greatly limit the soft furnishings in the later stages of the building. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides an assembly structure for prefabricated floor slabs to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for precast floor slabs, wherein the top surface of the connecting base is provided with a mating hole and a screw hole, a concrete base is fixedly installed on the top surface of the connecting base, exposed reinforcing bars are fixedly installed inside the concrete base, a first precast floor slab and a second precast floor slab are provided on the top surface of the connecting base, a connecting piece is provided on the top surface of the first precast floor slab and the second precast floor slab, and a fixing bolt is installed on the inner thread of the connecting piece.

[0008] Preferably, an auxiliary reinforcing bar is fixedly installed inside the precast floor slab, a positioning groove is provided on the left side of the top surface of the precast floor slab, a positioning hole is provided in the positioning groove, and exposed reinforcing bars are fixedly installed on the left and right sides of the precast floor slab.

[0009] Preferably, an auxiliary reinforcing rib 2 is fixedly installed inside the precast floor slab 2, a positioning groove 2 is opened on the top surface and side of the precast floor slab 2, a positioning hole 2 is opened in the positioning groove 2, and exposed steel ribs 4 and exposed reinforcing bars 5 are fixedly installed on the left and right sides of the precast floor slab 2.

[0010] Preferably, the positioning hole one and positioning hole two are through holes that run vertically through each other.

[0011] Preferably, several auxiliary reinforcing ribs one and two are fixedly installed at equal intervals on precast floor slab one and precast floor slab two.

[0012] Preferably, the positioning groove one corresponds to the positioning groove.

[0013] Compared with the prior art, this utility model provides an assembly structure for precast floor slabs, which has the following beneficial effects:

[0014] 1. The assembly structure of the precast floor slab involves first fixing and installing the connecting base according to the position shown in the drawings, then installing the first precast floor slab according to the position of the first positioning hole and the concrete base, and then placing and installing the second precast floor slab according to the position of the second positioning hole and the concrete base. Several auxiliary reinforcing bars 1 and 2 are fixedly installed at equal intervals on the first and second precast floor slabs. At this time, the exposed steel bar 2 on the left side of the first precast floor slab and the exposed steel bar 4 on the right side of the second precast floor slab are placed inside the connecting hole. The exposed steel bars 2 and 4 are then tied together with thin steel bars to further fix the first and second precast floor slabs.

[0015] 2. The assembly structure of this precast floor slab involves initially fixing the connecting piece by fitting it onto the outside of the concrete base and threading it into the screw holes with fixing bolts. This allows the connecting piece to distribute the weight of both precast floor slab one and precast floor slab two. After the initial installation is completed, concrete is poured onto the concrete surface and the top surface of the connecting base to further enhance the structural strength. The pre-embedded auxiliary reinforcing bars one and two can effectively improve the load-bearing capacity of the subsequently poured concrete. When pouring the concrete on the top surface of the connecting base, other strength-enhancing materials can be added to the concrete to improve its load-bearing capacity after pouring.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: an assembly structure for a precast floor slab, wherein a connecting base 1 has a mating hole 101 on its top surface, a screw hole 102 on its top surface, a concrete base 103 is fixedly installed on the top surface of the connecting base 1, an exposed steel bar 104 is fixedly installed inside the concrete base 103, a precast floor slab 2 and a precast floor slab 3 are provided on the top surface of the connecting base 1, a connecting piece 4 is provided on the top surface of the precast floor slab 2 and the precast floor slab 3, and a fixing bolt 5 is installed on the inner thread of the connecting piece 4.

[0023] Furthermore, an auxiliary reinforcing bar 201 is fixedly installed inside the precast floor slab 2. A positioning groove 202 is opened on the left side of the top surface of the precast floor slab 2. A positioning hole 203 is opened in the positioning groove 202. Exposed reinforcing bars 204 and 305 are fixedly installed on the left and right sides of the precast floor slab 2.

[0024] Through the above technical solution, after the precast floor slab 1 2 and precast floor slab 2 3 are installed through the connecting base 1, concrete can be poured on the surface to further improve the building strength. The pre-embedded auxiliary reinforcing bars 1 201 and 2 301 can effectively improve the bearing capacity of the subsequently poured concrete.

[0025] Furthermore, auxiliary reinforcing bars 2 301 are fixedly installed inside the precast floor slab 2 3, and positioning grooves 2 302 are opened on the top and sides of the precast floor slab 2 3. Positioning grooves 2 302 are provided with positioning holes 2 303, and exposed reinforcing bars 4 304 and 5 305 are fixedly installed on the left and right sides of the precast floor slab 2 3.

[0026] Through the above technical solution, precast floor slab 1 2 and precast floor slab 2 3 are installed in the butt joint hole 101 by exposed steel bars 204 and 304 on both sides. After being connected by binding with thin steel bars, the connecting piece 4 is sleeved on the outside of the concrete base 103, and the fixing bolt 5 is installed and fixed by thread.

[0027] Furthermore, positioning hole 1 203 and positioning hole 2 303 are through holes that run vertically through each other.

[0028] With the above technical solution, precast floor slab 1 2 and precast floor slab 2 3 can be aligned with the concrete base 103 and correctly placed on the top side of the connecting base 1 during installation.

[0029] Furthermore, several auxiliary reinforcing ribs 1 201 and 2 auxiliary reinforcing ribs 301 are fixedly installed at equal intervals on precast floor slab 1 2 and precast floor slab 2 3.

[0030] With the above technical solution, it is not necessary to embed steel bars again when pouring concrete for precast floor slab 1 and precast floor slab 2, which effectively improves the strength of the concrete poured later and avoids the safety hazards caused by insufficient concrete strength during subsequent use.

[0031] Furthermore, positioning slot 1 202 and positioning slot 2 302 correspond to each other.

[0032] Through the above technical solution, precast floor slab 1 2 and precast floor slab 2 3 can be further installed and fixed by connecting piece 4 after installation, so as to make preliminary connection for subsequent concrete pouring.

Then, place and install the precast floor slab 3 according to the position of the positioning hole 303 and the concrete base 103. At this time, the exposed steel bar 204 on the left side of the precast floor slab 2 and the exposed steel bar 304 on the right side of the precast floor slab 3 are placed inside the connecting hole 101. Then, the exposed steel bars 204 and 304 are tied with thin steel bars for further reinforcement. Precast floor slabs 1 and 2 are installed. The connecting piece 4 is fitted onto the outside of the concrete base 103 and fixed in the screw hole 102 by the fixing bolt 5. The connecting piece 4 distributes the weight of the precast floor slabs 1 and 2. After the initial installation is completed, concrete is poured on the concrete surface and the top surface of the connecting base 1 to further improve the building strength. When pouring on the top surface of the connecting base 1, other strength-increasing materials can be added to the concrete to make it better able to bear the load after pouring.
