The device closely laminates pre-buried steel sheet and lateral wall template through the elasticity to propping the spiral muscle, prevents that piping lane lateral wall concrete placement in-process from causing the position dislocation of pre-buried steel sheet, improves pre-buried steel sheet rigidity's accuracy, offers convenience for follow-up construction.
Description
Technical Field
The invention belongs to the technical field of civil engineering, and particularly relates to a fixing device for an embedded part on the side wall of a concrete pipe gallery.
Background
The utility tunnel has played an important role in the aspects of integrating city electric power, water supply, drainage, gas and other underground pipelines, guaranteeing pipeline safety, reducing road surface excavation, intensively utilizing underground space and the like.
At present, the position of an embedded part on the side wall of a concrete pipe gallery is fixed by binding and welding with a side wall steel bar, the position of the embedded part is easy to dislocate, dent and the like when concrete is poured by the method, the position accuracy of the embedded part cannot be ensured after the formwork is removed, and the construction requirement cannot be met.
Disclosure of Invention
The invention aims to improve the existing fixing mode for the side wall embedded part of the concrete pipe gallery, and provides a fixing device for the side wall embedded part of the concrete pipe gallery, which is convenient to operate, avoids the occurrence of position dislocation, sinking and the like of an embedded steel plate in the concrete pouring process, and ensures the position fixing accuracy of the embedded part after the form removal.
The invention is realized by adopting the following technical scheme:
the utility model provides a fixing device for concrete pipe gallery lateral wall built-in fitting, includes the horizontal longitudinal reinforcement of pre-buried in pipe gallery lateral wall concrete, vertical atress reinforcing bar and the lateral wall template that is used for pouring into a mould pipe gallery lateral wall concrete. A plurality of diagonal bracing spiral bars are welded and fixed between the vertical stressed steel bars located on two sides, the two ends of each diagonal bracing spiral bar are respectively welded and fixed with embedded steel plates, the embedded steel plates are tightly attached to the side wall template under the action of the diagonal bracing spiral bars, and steel plate anchor bars are arranged on the back surfaces of the embedded steel plates.
Every little unit of the device includes two welded connection nodes, the first node is to propping spiral muscle and vertical atress reinforcing bar, and the second node is to propping spiral muscle end and pre-buried steel sheet. And one oppositely-supported spiral rib is welded and connected with the two vertical stressed steel bars, so that the accuracy of the position of the spiral rib is ensured. And one oppositely-supported spiral rib is welded and connected with the centers of the two symmetrical embedded steel plate plates, so that the steel plates are uniformly stressed. And installing the side wall template in place, carrying out compression deformation on the supporting spiral rib, and tightly attaching the supporting spiral rib and the side wall template through elasticity.
Compared with the existing fixing mode, the oppositely-supported spiral ribs are arranged between the two symmetrical embedded steel plates, the embedded parts are tightly attached to the template through the elastic force generated after the oppositely-supported spiral ribs are deformed, the accuracy of the fixed positions of the embedded parts is improved, and great convenience is brought to subsequent construction.
The invention has reasonable design and good practical application value.

Fig. 2 is an enlarged schematic view of a portion a of fig. 1.
In the figure: 1-side wall formwork, 2-diagonal spiral reinforcement, 3-horizontal longitudinal reinforcement, 4-pipe gallery side wall concrete, 5-vertical stressed reinforcement, 6-embedded steel plate and 7-steel plate anchor reinforcement.
Detailed Description
The technical solution of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The utility model provides a fixing device for concrete pipe gallery lateral wall built-in fitting, as shown in figure 1, including bury horizontal longitudinal reinforcement 3, vertical atress reinforcing bar 5 in pipe gallery lateral wall concrete 4 in advance and be used for pouring into a mould lateral wall template 1 of pipe gallery lateral wall concrete 4, two lateral wall templates 1 are located both sides. As shown in fig. 2, be located a plurality of root welded fastening between the vertical atress reinforcing bar 5 of both sides to propping spiral muscle 2 (to propping spiral muscle 2 and vertical atress reinforcing bar 5 and become an organic whole through welded connection), every is to propping spiral muscle 2 both ends respectively welded fastening embedded steel plate 6 (to propping spiral muscle 2 end and embedded steel plate 6 and become an organic whole through welded fastening connection), embedded steel plate 6 hugs closely lateral wall template 1 under propping spiral muscle 2 effect, the 6 backs of embedded steel plate are equipped with steel sheet anchor bar 7. Have two welded connection nodes, first node is for propping spiral muscle 2 and vertical atress reinforcing bar 5, and second node is for propping 2 ends of spiral muscle and pre-buried steel sheet 6. And one oppositely-supported spiral rib 2 is welded and connected with two vertical stressed steel bars 5, so that the accuracy of the position of the spiral rib is ensured. And the oppositely-supported spiral rib 2 is welded with the centers of the two symmetrical embedded steel plate plates, so that the steel plates are uniformly stressed. The side wall formwork 1 is installed in place, the supporting spiral ribs 2 are compressed and deformed, and the supporting spiral ribs 2 are tightly attached to the side wall formwork 1 through elasticity.
During concrete implementation, the pre-buried steel sheet 6 of two symmetries of the inside lateral wall of piping lane is fixed in one and is to propping the both ends of spiral muscle 2, closely laminate the pre-buried steel sheet 6 to lateral wall template 1 through spiral muscle elasticity on, realize the accuracy of pre-buried steel sheet 6 positions fixed.
The specific implementation manner of the connection structure is as follows:
the first step is as follows: installing and binding a vertical stressed steel bar 5 and a horizontal longitudinal steel bar 3;
the second step is that: welding the oppositely-supported spiral ribs 2 and the vertical stressed steel bars 5 to form a whole;
the third step: welding the end parts of the oppositely-supported spiral ribs 2 with the embedded steel plates 6 to form a whole;
the fourth step: installing a pipe gallery side wall template 1, extruding the oppositely-supported spiral ribs 2, and tightly attaching the embedded steel plate 6 to the side wall template 1 through the elasticity of the oppositely-supported spiral ribs 2 to realize accurate positioning;
the fifth step: and pouring the concrete 4 on the side wall of the pipe gallery.
The device closely laminates pre-buried steel sheet 6 and lateral wall template 1 through the elasticity to propping spiral muscle 2, prevents that piping lane lateral wall concrete 4 from pouring the position dislocation that the in-process caused pre-buried steel sheet, improves the accuracy of pre-buried steel sheet 6 rigidity, offers convenience for follow-up construction.
