Description

Technical Field

[0001] This utility model relates to the field of precast cement slab technology, specifically a precast cement slab with pre-installed installation pipelines. Background Technology

[0002] Precast concrete slabs, as an industrialized building component, significantly improve construction efficiency and quality stability through factory prefabrication and on-site assembly. However, traditional precast slabs have the following technical drawbacks in terms of pipeline installation:

[0003] Secondary grooving damages the structure: Existing precast slabs do not have pre-embedded pipe channels, so grooving is required on the slab surface during construction, which can easily lead to concrete cracking and exposed steel bars, reducing the durability of the structure; 2. Low construction efficiency: Grooving operations rely on manual operation, which has poor precision and low efficiency, and requires additional handling of construction waste, increasing the construction period and cost; in addition, it is not possible to reliably place the pipes in the grooving.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: A precast concrete slab with pre-installed pipes includes a precast slab body 1; a pipe 2 is fixedly connected inside the precast slab body 1, the length of the pipe 2 matching the length of the precast slab body 1; clamping components 5 are provided at both ends of the pipe 2, and auxiliary components 6 are provided on both sides of the clamping components 5; the clamping components 5 include two guide rods 53, which are fixedly parallel inside the pipe 2, and an installation rod 51 is provided between the two guide rods 53. The two ends of the installation rod 51 are respectively movably sleeved with the two guide rods 53. A pipe clamp 54 is fixedly connected to the center of the bottom end of the installation rod 51, and side blocks 52 are fixedly connected to both sides of the pipe clamp 54. Several fixing rods 55 and several springs 56 are fixedly connected to one side of each of the two side blocks 52. Several fixed rods 55 are movably connected to two guide rods 53 respectively, and several springs 56 are respectively sleeved around the fixed rods 55; the auxiliary component 6 includes a sleeve block 61, which is fixed to the inner wall of the pipe 2. A plug block 62 is movably inserted into one side of the sleeve block 61. One side of the plug block 62 is fixedly connected to several fixed rods 55. A bolt 63 is threadedly connected to the outer side of the sleeve block 61. The end of the bolt 63 is tightly fitted to the outer side wall of the plug block 62. By directly embedding the pipe 2 during the precast slab pouring stage, the damage to the concrete structure caused by on-site grooving is avoided, the risk of cracking is reduced, and the service life is extended. Furthermore, the pipe clamp 54 and the auxiliary component 6 work together to clamp the pipe and ensure that the pipe is stably placed inside the pipe 2.

[0019] In use, insert pipe 2 into pipe 2. After the pipe is fully inserted, press down the installation rod 51. The installation rod 51 drives the pipe clamp 54 to move steadily down along the guide rod 53. The pipe clamp 54 clamps the pipe through its own elasticity. During the deformation process, the pipe clamp 54 pushes the fixing rod 55 through the side block 52. The fixing rod 55 drives the insertion block 62 to move within the sleeve block 61. The side block 52 and the guide rod 53 also compress the spring 56. After the pipe clamp 54 has finished clamping the pipe, the pipe clamp 54 returns to its initial state through the rebound force. The side block 52, the fixing rod 55 and the insertion block 62 move back through the rebound force of the spring 56. Then rotate the bolt 63 so that the end of the bolt 63 is tightly attached to the outer wall of the insertion block 62, restricting the insertion block 62 and preventing the insertion block 62 and the fixing rod 55 from shifting, thereby preventing the pipe clamp 54 from deforming and ensuring the clamping effect of the pipe clamp 54 on the pipe, thus ensuring stability.

[0020] Example 2, the technical solution of which differs from Example 1 is as follows: a positioning plate 8 is also fixedly connected to the center of the bottom wall of the pipe 2, the upper end of the positioning plate 8 is set as an arc surface, and the pipe is placed on the positioning plate 8 to facilitate quick positioning of the pipe;

[0021] At the two bends at the upper end of pipe 2, arc-shaped spring pieces 7 are also fixedly connected. When inserted into the pipe, the pipe will squeeze the spring pieces 7. The rebound force of the spring pieces 7 will squeeze the pipe, thereby further ensuring the stability of the pipe.

[0022] Several protrusions 9 are also fixed on the inner wall of the pipe clamp 54 to ensure the clamping effect on the pipe;

[0023] Two protruding corners 4 are provided on one edge of the precast slab body 1. A notch 3 is provided at the other end of the precast slab body 1 at the position corresponding to the two protruding corners 4. The two protruding corners 4 match the two notches 3 respectively, so that the two protrusions 9 are inserted into the notches 3 on the other precast slab body 1, thereby facilitating the quick splicing of the two precast slab bodies 1 together.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
