Description

Technical Field

[0001] The utility model belongs to the technical field of bridge engineering system construction, and particularly relates to a cap steel template structure. Background Art

[0002] The bridge cap refers to a reinforced concrete platform that connects the tops of the piles and is set up on the top of the foundation piles to bear and distribute the loads transmitted by the pier body. It is formed by laying steel formwork inside the foundation pit, erecting the cap steel bars, and then pouring concrete in the pouring space formed by the steel formwork. Under normal circumstances, the cap formwork is reinforced and fixed by the tension screws combined with the sleeve inside the steel formwork. The principle is to reinforce the steel formwork by tightening the two sides. During the on-site construction, due to the small working space in the foundation pit, it may be difficult for the tension screws to penetrate the cap formwork, making it difficult to construct the tension screws, affecting the construction progress and slowing down the construction efficiency. Generally, the cap steel formwork on the construction site is reinforced by tension bolts combined with sleeves. After the concrete pouring is completed, the sleeve remains inside the cap, which is difficult to reuse and causes waste of materials. Therefore, we propose a cap steel formwork structure to solve the above problems. Utility Model Content

[0020] In order to solve the problems of difficult construction and difficult reuse, the utility model provides a foundation steel formwork structure. The foundation steel formwork structure is further described below with specific embodiments combined with the accompanying drawings.

[0021] See also Figure 1 to Figure 4 As shown, a cap steel formwork structure includes:

[0022] The formwork system is set up in a circle in the foundation pit to form a pouring space for pouring the cap;

[0023] The support system comprises a steel sheet pile 1 which is located at the periphery of the formwork system and is arranged close to the inner wall of the foundation pit, and a support rod 4 which is supported between the steel sheet pile 1 and the formwork system, and the length of the support rod 4 is adjustable.

[0024] Specifically, the steel sheet pile 1 as a support system can provide lateral support force to the formwork 2 through the support rod 4 to ensure that when pouring concrete in the pouring space, the formwork 2 is not stretched out, thereby improving stability, and the overall structure can be disassembled and reused repeatedly, which can greatly improve the quality of the cap concrete pouring and meet the concept of high-quality construction; after the cap reinforcement is tied, the formwork 2 is first hoisted to the edge of the cap and the line-laying position is then supported by the support rod 4 on the back of the formwork 2 to the foundation pit steel sheet pile 1, thereby improving the convenience of the cap steel formwork construction; and the device has a simple structure, is safe and reliable, is easy to operate, saves labor, and improves construction efficiency.

[0025] Among them, the formwork system is composed of several formworks 2 spliced ​​end to end, the number of steel sheet piles 1 is equal to the number of formworks 2 and is arranged one by one on the periphery of the several formworks 2, and at least one support rod 4 is arranged between each pair of steel sheet piles 1 and formworks 2.

[0026] By arranging support rods 4 between each pair of steel sheet piles 1 and the formwork 2, the steel sheet piles 1 provide support force for the formwork 2 through the support rods 4, so that the formwork 2 is stable in use.

[0027] The template 2 has vertical back ribs 3 arranged on one side facing the steel sheet pile 1 , and each back rib 3 corresponds to at least one support rod 4 , which is connected to the template 2 via the corresponding back rib 3 .

[0028] The back ribs 3 are provided to strengthen the overall strength of the formwork 2, making it more stable during use. The support rods 4 are correspondingly provided on the back ribs 3, which can be used to support the formwork 2 well and improve stability.

[0029] The support rod 4 includes a core rod 42 and a sleeve 41 . The core rod 42 is screwed to the sleeve 41 , and the screwing depth is adjustable. The sleeve 41 is detachably connected to the back rib 3 .

[0030] By screwing the core rod 42, when it is retracted into the sleeve 41, the overall length of the support rod 4 can be shortened, and when it is extended out of the sleeve 41, the overall length of the support rod 4 can be extended, so that the overall length of the support rod 4 can be well adjusted by adapting the distance between the template 2 and the steel sheet pile 1, which is convenient for use.

[0031] The support rod further includes a butt plate 43 , which is connected to one end of the core rod 42 away from the sleeve 41 and is used to butt against the steel sheet pile 1 .

[0032] The entire length of the support rod 4 is adjusted by screwing the core rod 42, so that the abutment plate 43 on the core rod 42 abuts against the steel sheet pile 1, that is, the support rod 4 provides a supporting force to the formwork 2 through the steel sheet pile 1 to stabilize it.

[0033] The back rib 3 is connected to the template 2 by welding, and the sleeve 41 is connected to the back rib 3 by threading.

[0034] By adopting the above design, the back rib 3 and the template 2 can be firmly connected, and the sleeve 41 is detachable, which is convenient for disassembly after the construction is completed, so as to facilitate repeated use.

[0035] The steel sheet pile 1 is formed by overlapping a plurality of plates 11 end to end, and the leading and trailing edges of each plate 11 are formed with interlocking portions 111 for overlapping adjacent plates 11 .

[0036] By providing interlocking parts 111 at both the head and the tail of the plate 11, the plate 11 can be overlapped one by one by using the interlocking parts 111 to form a steel sheet pile 1, which is convenient for installation and use as well as subsequent disassembly.
