Description

Technical Field

[0002] Hollow bridge slab is also called hollow slab. Hollow slab is made of cast concrete, and the cross section of the slab is made hollow. Hollow slab is lighter than solid slab of the same span, easy to transport and install, and smaller in building height than T-beam of the same span, so it is more commonly used in small span bridges. At present, there are many shapes of hollow areas of hollow slabs, and the current hollow slab house construction has been changed to frame structure and reinforced concrete structure, so the safety quality of house construction has also been further improved. Prefabricated hollow slab has a span of 2.4-6m, a slab height of 120 or 180mm, and a slab width of 600mm, 900mm, 1200mm, etc.

[0003] When installing the current hollow bridge decks, the hollow bridge decks to be cast are placed in the designated area in sequence. Concrete casting grooves are opened at both ends of the hollow bridge decks. After the two hollow bridge decks are fitted together, the two casting grooves form a concrete casting area. Then, concrete is poured into the casting area to connect and fix the two adjacent hollow bridge decks.

[0004] However, currently the hollow bridge slabs are only placed together before the concrete is poured.

The first limiting column 4043 and the first slider 4042 are arranged to facilitate the vertical limiting of the first clamping block 404, thereby ensuring the stability of the horizontal movement of the first clamping block 404. It can be further explained that the inner wall of the first placement groove 401 squeezes the first clamping block 40 4 and drives the first clamping block 404 to move toward the inside of the connecting block 403. At this time, the first spring 4041 is squeezed by force. Similarly, the other first clamping block 404 is squeezed by the inner wall of the second placement groove 402 and moves toward the inside of the connecting block 403. When the first clamping block 404 moves to the same level as the first clamping groove, the first spring 4041 returns to its original state and drives the two first clamping blocks 404 to return to their original state. The first clamping blocks 404 move and engage with the first clamping grooves on the inner walls of the first placement groove 401 and the second placement groove 402, respectively.

[0031] See also Figure 3 and Figure 4One side of the second clamping block 405 is fixedly connected with a second spring 4051, and the other side of the second spring 4051 is fixedly connected with the fixing plate 406.

The first pouring groove 5 and the second pouring groove 501 are used for pouring concrete, thereby facilitating the stability of the connection between the first hollow bridge slab 1 and the second hollow bridge slab 2. It can be further explained that the second clamping block 405 moves and contacts with the inner wall of the first placement groove 401. Since one side of the second clamping block 405 is also set to be inclined, the second clamping block 4 05 moves toward the inner wall of the connecting block 403 under the pressure of the inner wall of the first placement groove 401, and the second spring 4051 is squeezed by the force.

The second clamping blocks 405 move and respectively engage with the second clamping grooves inside the first placement groove 401 and the second placement groove 402.

[0032] Working principle: When in use, first, when installing the first hollow bridge plate 1 and the second hollow bridge plate 2, first, place the second hollow bridge plate 2 on one end of the first hollow bridge plate 1, at this time, the first casting groove 5 and the second casting groove 501 are attached to form a casting area, and the first placement groove 401 and the second placement groove 402 are attached to form a placement area;

[0033] Secondly, the staff lifts the connecting block 403 by the handle 4031 and moves the connecting block 403 horizontally to the top of the placement area, and then moves the handle 4031 downward, the handle 4031 moves downward and drives the connecting block 403 to move, the connecting block 403 moves and drives the first clamping block 404 and the second clamping block 405 to move downward, when the first clamping block 404 moves and contacts the inner wall of the first placement groove 401, the inner wall of the first placement groove 401 squeezes the first clamping block 404 and drives the first clamping block 404 to move toward the inside of the connecting block 403, at this time, the first spring 4041 is squeezed by force, and similarly, the other first clamping block 404 also moves toward the inside of the connecting block 403 under the squeezing of the inner wall of the second placement groove 402, when the first clamping block 404 moves to the same horizontal height as the first clamping groove, the first spring 4041 returns to its original state and drives the two first clamping blocks 404 to reset and move, the first clamping block 404 moves and respectively engages with the first clamping grooves on the inner walls of the first placement groove 401 and the second placement groove 402;

[0034] At the same time, the second clamping block 405 moves and contacts the inner wall of the first placement groove 401. Since one side of the second clamping block 405 is also set to be inclined, the second clamping block 405 moves toward the inner wall of the connecting block 403 under the pressure of the inner wall of the first placement groove 401, and the second spring 4051 is squeezed. Similarly, the other second clamping block 405 also moves toward the inner wall of the connecting block 403. When the second clamping block 405 moves to the same horizontal height as the second clamping groove, the second spring 4051 returns to its original state and drives the two second clamping blocks 405 to reset and move. The second clamping block 405 moves and engages with the second clamping grooves inside the first placement groove 401 and the second placement groove 402 respectively.

[0035] Then, the first hollow bridge slab 1 and the second hollow bridge slab 2 are placed in sequence, and then the connecting blocks 403 are placed in the formed placement area in sequence. After the placement is completed, concrete can be poured into the pouring area and the placement area.

[0036] Finally, by opening the first placement groove 401 and the second placement groove 402, the contact area of ​​the casting area of ​​the first hollow bridge deck 1 and the second hollow bridge deck 2 is increased, thereby increasing the connectivity of the first hollow bridge deck 1 and the second hollow bridge deck 2. At the same time, by setting the connecting block 403, the first clamping block 404 and the second clamping block 405, the connectivity of the first placement groove 401 and the second placement groove 402 is further increased, so that the first hollow bridge deck 1 and the second hollow bridge deck 2 can be stably connected when they are initially placed. Compared with the traditional method of only placing the first hollow bridge deck 1 and the second hollow bridge deck 2 in a close fit, the stability of the connection between the first hollow bridge deck 1 and the second hollow bridge deck 2 is improved, which is convenient for the subsequent concrete pouring process and avoids the appearance of a gap between the first hollow bridge deck 1 and the second hollow bridge deck 2, which causes the concrete to flow to the bottom of the first hollow bridge deck 1 and the second hollow bridge deck 2.
