Description

Technical Field

[0001] The utility model belongs to the technical field of underground garage roof construction, and in particular relates to a molded construction device for expansion joints of underground garage roofs. Background Art

[0002] Concrete pouring is a vital part of underground garage construction. When pouring the underground garage roof over a large area, expansion joints with a width of 1-2 cm are required to prevent uneven settlement or temperature shrinkage. When the expansion joints are installed, they are generally filled with mold construction devices to enhance the stability of the expansion joints and ensure a firm connection between the expansion joints and the garage roof.

[0003] In a Chinese patent with publication number CN219219784U, a molded construction system for expansion joints of underground garage roofs is disclosed, in which an additional waterproof layer is directly made on the surface of the anti-seepage micro-expansion concrete, and the waterproof layer is raised, which has a good waterproof effect and enables the waterproof layer and the waterproof layer above the garage roof to become one, further improving the waterproof effect of the garage roof; however, in actual use, the above-mentioned molded construction system for expansion joints of underground garage roofs is generally made by laying the waterproof layer on the concrete surface, but there is a lack of supporting components on the waterproof layer, which makes it easy for the waterproof layer and the concrete to pile up with each other during laying and is relatively fragile as a whole, resulting in a decrease in the tensile strength of the waterproof layer, causing cracks to occur, thereby affecting the stability of the waterproof layer and reducing the protective effect of the mold construction device on the expansion joint.

[0004] In order to solve the above problems, the present application proposes a molded construction device for expansion joints of underground garage roofs. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-Figure 4 The molded construction device for the expansion joint of the roof of an underground garage shown in the figure comprises:

[0028] Two concrete structures 1, and an expansion joint is formed between the two concrete structures 1;

[0029] The expansion joint mold frame 2 is used for filling and plugging the expansion joint. The expansion joint mold frame 2 includes a mold frame 23 installed in the expansion joint and an anti-seepage micro-expansion concrete 21 filled in the mold frame 23, and a waterproof layer 22 is laid on the top of the anti-seepage micro-expansion concrete 21; wherein, the structures and principles of the mold frame 23, the waterproof layer 22 and the anti-seepage micro-expansion concrete 21 are all prior arts, and specific reference is made to the comparative document (publication number CN219219784U, and the patent name is a mold construction system for underground garage roof expansion joints), which will not be repeated here;

[0030] The stabilizing component 3 is used to firmly connect the waterproof layer 22 and the anti-seepage micro-expansive concrete 21. The stabilizing component 3 includes two support frames 31 symmetrically installed at the bottom end of the waterproof layer 22 and two brackets 32 symmetrically installed in the anti-seepage micro-expansive concrete 21, and the two brackets 32 are fixedly connected to the two support frames 31; a through groove is also provided on the corresponding side of the two support frames 31; and the support principle between the stabilizing component 3 and the waterproof layer 22 and the anti-seepage micro-expansive concrete 21 adopts the existing steel bar support principle, which is well known in the technical field and will not be repeated here; one side of the two brackets 32 is provided with an installation groove 34, and a middle frame 33 is fixed between the two installation grooves 34; an anchor frame 35 is also installed in the mold frame 23, and a stabilizing groove 36 for inserting the bracket 32 ​​is provided on one side of the anchor frame 35.

[0031] As can be seen from the above, when in use, the middle frame 33 is first inserted into the installation groove 34 to maintain a stable connection between the two brackets 32, and then the bracket 32 ​​is inserted into the stable groove 36 to connect and fix the anchor frame 35 with the bracket 32, and the combination forms a concave bracket, and the anchor frame 35 is fixed in the mold frame 23, and the whole is stably installed in the mold frame 23, and the anti-seepage micro-expansion concrete 21 is poured in the mold frame 23, and then the waterproof layer 22 is laid on the anti-seepage micro-expansion concrete 21, and then the anti-seepage micro-expansion concrete 21 and the waterproof layer 22 are poured. During laying, they are bonded to the concave bracket and support each other, which can resist pressure and tension in the horizontal and vertical directions, and provide effective support between the waterproof layer 22 and the anti-seepage micro-expansive concrete 21, so that the waterproof layer 22 and the anti-seepage micro-expansive concrete 21 have good stability, thereby solving the problem that the existing waterproof layer 22 and the anti-seepage micro-expansive concrete 21 are piled up with each other during laying and are relatively fragile as a whole, resulting in a decrease in the tensile strength of the waterproof layer 22 and cracking. This greatly enhances the stability of the waterproof layer 22 and improves the protective effect of the mold construction device on the expansion joint.

One side of the anti-skid pad 45 extends to the outside of the slide groove 44 and contacts one side of the connecting rod 42; an ear clamping plate 47 is also fixed to the bottom end of the connecting rod 42, and a clamping groove 46 corresponding to the ear clamping plate 47 is provided on the inner bottom wall of the connecting cavity 41, and the clamping groove 46 and the ear clamping plate 47 are clamped and fixed.

[0034] Through the above technical solution:

[0035] When the two brackets 32 and the middle frame 33 are installed, the connecting rod 42 is inserted into the connecting cavity 41 and pushed downward, so that the connecting rod 42 contacts the anti-skid pad 45 when moving downward along the connecting cavity 41, and then the anti-skid pad 45 is deformed by the force, thereby enhancing the contact surface with one side of the connecting rod 42, so that the connecting rod 42 can move stably in the connecting cavity 41, and the connecting rod 42 moves to the bottom wall inside the connecting cavity 41, and the ear clamping plate 47 is clamped and fixed with the clamping groove 46, so that the limit support 43 contacts the top of the support frame 31, so that the two support frames 31 can be stably connected, which can ensure that the support frame 31 is fixed at the required position, prevent the support frame 31 from loosening or shifting, and effectively improve the stability of the support frame 31.
