Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a template fastening device for road and bridge construction. Background Technology

[0002] During the construction of roads and bridges, formwork is usually used to provide temporary support. Its geometric structure can withstand the self-weight of the formwork and the external loads acting on it, thereby ensuring the quality and safety of concrete construction in road and bridge projects.

[0003] For example, Chinese utility model patent application number 202123282250.3, entitled "A Formwork Fastening Device for Road and Bridge Construction," includes a fastening unit. The fastening unit includes a baffle and a support member. The support member includes a support plate and a support rod. The support plate is hinged to the baffle. The bottom surface of the support plate and the bottom surface of the baffle are on the same horizontal plane. One end of the support rod is hinged to the surface of the baffle, and the other end of the support rod is slidably connected to the surface of the support plate. The support rod is a telescopic rod.

[0004] In the aforementioned prior art, a stable triangular shape can be formed by the baffle, support plate, and support rod, which can withstand the self-weight of the building formwork and the external loads acting on it, ensuring the quality and safety of road and bridge construction. However, the support rod is fixed by bolts passing through through holes. When it is necessary to change the angle of the baffle, the bolts need to be unscrewed. After the support rod is adjusted, it is fixed again with bolts. Since the bolts need to be disassembled and reassembled each time the angle is adjusted, the adjustment process is time-consuming, thereby reducing construction efficiency.

[0005] Based on this, a formwork fastening device that is convenient for road and bridge construction is provided. Utility Model Content

[0006] The present invention aims to overcome the defects in the prior art and provide a template fastening device for road and bridge construction that can quickly adjust the angle between the support plate and the baffle, thereby improving construction efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a template fastening device for road and bridge construction, comprising a support plate, a baffle, a first connecting block, a slide rail, a second connecting block, a support rod, and a limiting mechanism. Several sets of slide rails are arranged parallel to each other on the support plate. A second connecting block is slidably disposed inside each slide rail. A first connecting block corresponding to the second connecting block is fixedly disposed on the baffle. The first and second connecting blocks are connected by the support rod. Limiting mechanisms for positioning and fixing the second connecting block to the slide rail are provided on both sides of the second connecting block. The limiting mechanism includes a mounting box, a tension block, and a spring. The tension block includes abutment blocks on both sides and an insert rod located in the middle. A spring is disposed between the abutment blocks and the inner wall of the mounting box. The expansion of the spring causes the insert rod to insert into the slide rail and the second connecting block, achieving connection between the two. The compression of the spring causes the insert rod to disengage from the second connecting block and the slide rail, facilitating the sliding of the second connecting block within the slide rail.

[0008] As a preferred embodiment of this utility model, the second connecting block includes a mounting block built into the slide rail. The mounting block has round holes on both sides. The slide rail is provided with a plurality of mounting holes that can be adapted to the round holes at equal intervals. The insertion rod can be inserted into the mounting holes and round holes to realize the connection between the slide rail and the second connecting block.

[0009] As a preferred embodiment of the present invention, the second connecting block includes a positioning part located at the upper end of the mounting block, and the positioning part has at least two downward protruding positioning blocks on both sides facing the mounting box, and the mounting box has positioning grooves adapted to the positioning blocks.

[0010] As a preferred embodiment of this utility model, the stretching block includes a guide rod, which is located on both sides of the stretching block and parallel to the insertion rod. The mounting box has a guide groove adapted to the guide rod.

[0011] As a preferred embodiment of this utility model, the mounting box includes a through hole, which is adapted to the insertion rod of the tension block.

[0012] As a preferred embodiment of the present invention, the mounting box includes an upper shell and a lower shell, the top of the lower shell forms an insertion interface, and the bottom of the upper shell forms a plug-in portion adapted to the insertion interface.

[0013] As a preferred embodiment of this utility model, the upper housing includes a countersunk hole, and the lower housing has a threaded hole adapted to the countersunk hole.

[0014] As a preferred embodiment of this utility model, it includes a first fixing rod and a second fixing rod. The first fixing rod passes through the first connecting block and the support rod to connect the two. The second fixing rod passes through the second connecting block and the support rod to connect the two.

[0015] As a preferred embodiment of this utility model, the baffle includes a storage groove, and a first connecting block is fixedly disposed in the storage groove. The length of the storage groove is greater than the length of the slide rail.

[0016] As a preferred embodiment of this utility model, the baffle has several positioning groups at both ends, the positioning groups realize the connection between two adjacent baffles, and the positioning groups include grooves and protruding ridges that can be adapted to the grooves.

[0017] The beneficial effects of this utility model are:

[0018] 1. The limiting mechanism of this utility model, through the cooperation of the mounting box, the tension block and the spring, when the spring is compressed, the insertion rod disengages from the round hole and the mounting hole, and the second connecting block can slide inside the slide rail.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-7 As shown below, the structure and function of a formwork fastening device for road and bridge construction will be described in detail.

[0031] A formwork fastening device for convenient road and bridge construction includes a support plate 1, a baffle 2, a first connecting block 3, a slide rail 4, a second connecting block 5, a support rod 6, and a limiting mechanism 7. Several sets of slide rails 4 are arranged parallel to each other on the support plate 1. A second connecting block 5 is slidably disposed inside each slide rail 4. A first connecting block 3 corresponding to the second connecting block 5 is fixedly disposed on the baffle 2. The first connecting block 3 and the second connecting block 5 are connected by the support rod 6. The second connecting block 5 has positioning and fixing features on both sides for positioning and fixing it to the slide rail. The limiting mechanism 7 on the rail 4 includes a mounting box 71, a tension block 72, and a spring 73. The tension block 72 includes abutment blocks 721 on both sides and a rod 722 located in the middle. A spring 73 is provided between the abutment blocks 721 and the inner wall of the mounting box 71. The expansion of the spring 73 allows the rod 722 to be inserted into the slide rail 4 and the second connecting block 5 and to connect the two. The compression of the spring 73 allows the rod 722 to disengage from the second connecting block 5 and the slide rail 4, facilitating the sliding of the second connecting block 5 within the slide rail 4.

[0032] A first fixing rod 8 is provided between the first connecting block 3 and the support rod 6. The first fixing rod 8 passes through the first connecting block 3 and the support rod 6 to connect the two. A second fixing rod 9 is provided between the second connecting block 5 and the support rod 6. The second fixing rod 9 passes through the second connecting block 5 and the support rod 6 to connect the two.

[0033] When the tension block 72 is fixed inside the mounting box 71, one end of the tension block 72 that fixes the insertion rod 722 is not covered by the mounting box 71. Thus, by holding this end of the tension block 72, the tension block 72 can move inside the mounting box 71 along the height direction of the spring 73, which facilitates the insertion rod 722 to enter the slide rail 4 and the second connecting block 5, or the insertion rod 722 to disengage from the slide rail 4 and the second connecting block 5.

[0034] The second connecting block 5 includes a mounting block 51 built into the slide rail 4. The mounting block 51 has round holes 511 on both sides. The slide rail 4 is provided with a plurality of mounting holes 41 that can be adapted to the round holes 511 at equal intervals. The insertion rod 722 can be inserted into the mounting holes 41 and the round holes 511 to realize the connection between the slide rail 4 and the second connecting block 5.

[0035] The second connecting block 5 includes a positioning part 52 located at the upper end of the mounting block 51. The positioning part 52 has at least two downward protruding positioning blocks 521 on both sides facing the mounting box 71. The mounting box 71 has positioning grooves 711 that are adapted to the positioning blocks 521. The cooperation of the positioning blocks 521 and the positioning grooves 711 enables the second connecting block 5 and the limiting mechanism 7 to be positioned. Firstly, when the second connecting block 5 moves along the slide rail 4, the limiting mechanism 7 also moves accordingly, which facilitates quick adjustment. Secondly, when the tension block 72 is held to fix one end of the insertion rod 722, the mounting box 71 will not move with the tension block 72 due to the positioning of the positioning blocks 521 and the positioning grooves 711, which makes it convenient for the insertion rod 722 to perform its function.

[0036] In use, determine the required angle between the support plate 1 and the baffle 2, then hold the tension block 72 and pull one end of the fixed rod 722 outward. The spring 73 is compressed, and the rod 722 disengages from the round hole 511 and the mounting hole 41. The second connecting block 5 can slide inside the slide rail 4. When the second connecting block 5 slides to the designated position inside the slide rail 4, the tension block 72 is no longer held, the spring 73 relaxes, and exerts a counter-pushing force on the abutment block 721. Then, the rod 722 on the tension block 72 is inserted into the mounting hole 41 and the round hole 511. The second connecting block 5 is positioned and fixed inside the slide rail 4, and the support plate 1 and the baffle 2 are set at the designated angle.

[0037] This utility model uses a limiting mechanism 7 to achieve rapid positioning and fixing of the second connecting block 5 inside the slide rail 4, thereby enabling rapid adjustment of the angle between the support plate 1 and the baffle 2, improving construction efficiency. The geometric structure of the support plate 1 and the baffle 2 can withstand the self-weight of the building formwork and the external loads acting on it, thus ensuring the quality and safety of concrete construction in road and bridge engineering.

[0038] The structure and function of the limiting mechanism 7 are described in detail below;

[0039] like Figures 3-7 As shown, the tension block 72 includes a guide rod 723, which is located on both sides of the tension block 72 and parallel to the insertion rod 722. The mounting box 71 has a guide groove 712 adapted to the guide rod 723, and the guide groove 712 guides the guide rod 723 located therein.

[0040] Mounting box 71 includes a through hole 713, which is adapted to the insertion rod 722 of tension block 72 and guides the insertion rod 722 located therein.

[0041] The mounting box 71 includes an upper housing 714 and a lower housing 715. The lower housing 715 has a plug-in interface 7151 at its top, and the upper housing 714 has a plug-in portion 7141 at its bottom that is adapted to the plug-in interface 7151.

[0042] The upper housing 714 includes a countersunk hole 7142, and the lower housing 715 has a threaded hole 7152 that is adapted to the countersunk hole 7142.

[0043] Specifically, the guide groove 712 provided on the mounting box 71 can be used to insert the guide rod 723 of the tension block 72, and the through hole 713 provided on the mounting box 71 can be used to insert the insertion rod 722 of the tension block 72. The tension block 72 can make stable linear movement inside the mounting box 71 through the insertion of the guide rod 723 and the insertion rod 722 in the guide groove 712 and the through hole 713 of the mounting box 71, thus ensuring the stability of the fit between the mounting box 71 and the tension block 72.

[0044] Furthermore, the mounting box 71 is divided into an upper shell 714 and a lower shell 715, which facilitates the insertion and installation of the tension block 72 and the spring 73. The connection between the upper shell 714 and the lower shell 715 can be achieved by either plugging in the connector 7151 and the connector 7141 or by threading the bolts in the countersunk hole 7142 and the threaded hole 7152. Of course, if the plugging in the connector 7151 and the connector 7141 is deemed unstable, additional bolts can be added to further secure the connection between the upper shell 714 and the lower shell 715.

[0045] In use, the tension block 72 is placed into the lower housing 715. At this time, the insertion rod 722 is located in the through hole 713, the guide rod 723 is located in the guide groove 712, and the spring 73 is placed between the abutment block 721 and the inner wall of the lower housing 715. Furthermore, the upper housing 714 and the lower housing 715 are connected by bolts or plugs. The assembled limiting mechanism 7 is placed below the second connecting block 5.

[0046] The limiting mechanism 7 of this utility model, through the cooperation of the mounting box 71, the tension block 72, and the spring 73, when the spring 73 is compressed, the insertion rod 722 disengages from the round hole 511 and the mounting hole 41, and the second connecting block 5 can slide inside the slide rail 4. When the second connecting block 5 slides to the designated position inside the slide rail 4, when the spring 73 is relaxed, the insertion rod 722 inserts into the mounting hole 41 and the round hole 511, realizing the positioning and fixing of the second connecting block 5 inside the slide rail 4, thereby quickly adjusting the angle between the support plate 1 and the baffle 2.

[0047] Furthermore, the structure and function of baffle 2 will be described in detail below;

[0048] like Figures 1-2 As shown, the baffle 2 includes a storage groove 21, in which a first connecting block 3 is fixedly installed. The length of the storage groove 21 is greater than the length of the slide rail 4. The storage groove 21 can accommodate parts such as support rods 6, which facilitates the storage of some parts after the template fastening device is disassembled.

[0049] The baffle 2 has several positioning groups 22 at both ends. The positioning groups 22 can realize the connection between two adjacent baffles 2. The positioning groups 22 include grooves 221 and protrusions 222 that can be adapted to the grooves 221.

[0050] Specifically, the arrangement order of the grooves 221 and the ridges 222 in the positioning groups 22 on both sides of the baffle 2 is different. For example, the arrangement order in the positioning group 22 on one side is groove 221 and ridge 222, while the arrangement order on the other side is ridge 222 and groove 221, which facilitates the connection of adjacent baffles 2.

[0051] The positioning group 22 provided on the baffle 2 of this utility model facilitates the splicing between the baffles 2 and can be applied to different road and bridge construction environments. The storage slot 21 provided facilitates the storage of the device after the operation is completed.
