Description

Technical Field

[0001] This invention belongs to the field of engineering construction equipment technology, specifically a protective device for post-cast strips in buildings. Background Technology

[0002] Post-pouring strips in buildings are used to prevent cracks from appearing in the poured reinforced concrete due to its own structural shrinkage or settlement. Generally, support formwork is arranged in advance during concrete pouring to reserve post-pouring strips.

[0003] Since the post-cast strip is placed directly on the pre-tied steel mesh, many post-cast strips currently use fine steel ropes woven into a dense wire mesh to block the flow of concrete when setting up the support formwork. However, due to the cumbersome weaving of the wire mesh, it takes a long time to dismantle it later. Therefore, some directly use practical support formwork for protection. For example, patent CN102352688B discloses a post-cast strip support device, which can block the concrete poured on both sides through baffles, and adjust the movement of the baffles on both sides by controlling the movement of the baffles on both sides through the adjusting screw, adjusting frame and nut in the middle.

[0004] While the current support formwork has improved in terms of deployment efficiency, it also has some problems, such as: long deployment and dismantling time and low deployment and dismantling efficiency; the components of the support formwork are too precisely matched, as in the aforementioned patent, during pouring, concrete inevitably drips onto the components, making them inconvenient to use; and each component of the support formwork is stored separately, making it easy to lose, requiring a long search time during installation, resulting in low work efficiency. Summary of the Invention

[0005] To address the above problems, this invention provides a protective device for post-cast strips in buildings, which solves the problems of low efficiency in disassembling and assembling support formwork, inconvenience in use, and easy loss.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a protective device for post-cast strips in buildings, comprising symmetrically arranged templates, a sliding column in the middle of the templates, a sliding seat movably sleeved on the sliding column, and support members connected to the templates on both sides of the sliding seat.

[0007] A top pressing mechanism is provided above the slide to drive it up and down. When the slide moves up and down, it drives the templates on both sides to move towards the middle to disassemble the mold, or to separate and press the templates to the sides.

[0008] The template has a cavity on the side near the sliding column to accommodate the sliding column and support components. The two templates can be interlocked to form a box that is easy to transport.

[0009] Compared with the prior art, the beneficial effects of the present application are that: by means of top pressing, the formwork is tightly pressed to the two sides, which can avoid the formwork yielding to the poured concrete during pouring, ensuring the stability of the poured concrete during pouring and molding and solidification, the accommodation cavity is arranged in the formwork, which can be completely accommodated in the accommodation cavity after use, and the two formworks can be spliced into a box, which is more convenient for storage and transportation, can avoid the loss of some parts, and is more convenient for installation.

[0010] As a further improvement of the above-mentioned scheme, the top pressing mechanism comprises a sliding sleeve sleeved on the slide column, and the sliding sleeve is located above the slide base;

[0011] A handle is hingedly arranged on the sliding sleeve and can be pulled to flip it, a base is fixedly arranged at the lower end of the slide column, and a connecting rod is hingedly arranged on the base.

[0012] The improved technical effect is that: by arranging the top pressing mechanism, the handle can be pulled to make the sliding sleeve push the slide base to slide down and press the formwork on both sides during installation, achieving the effect of quick locking, which can avoid the dripping of concrete during pouring and the inflexible use.

[0013] As a further improvement of the above-mentioned scheme, a first spring is arranged between the bottom end of the slide base and the slide column;

[0014] A locking box is fixedly arranged at the top of the slide column, and a locking assembly for clamping the handle is arranged in the locking box.

[0015] The improved technical effect is that: the handle can be fixed by the locking assembly to avoid flipping, so that the formwork on both sides can be continuously pressed, and the first spring can provide an upward elastic force to the slide base, which can push the slide base to move upward during disassembly, thereby unloading the formwork and saving labor.

[0016] As a further improvement of the above-mentioned scheme, a slot is arranged on the locking box and communicates with the inner cavity of the locking box, and a clamping pin is arranged on the side surface of the handle and can be clamped into the slot;

[0019] As a further improvement of the above scheme, the locking member is connected with a second spring and a spring plate for driving the locking member to reset;

[0020] A guide groove is arranged on the inner cavity wall of the locking box for facilitating the movement of the locking member;

[0021] The locking member is fixedly connected with an unlocking member, the unlocking member penetrates the locking box upward, the unlocking member pulls the locking member to release the locking of the locking pin, and the unlocking member is further connected with a linkage member for synchronously pulling multiple unlocking members.

[0022] The improved technical effects are that the guide groove guides the rotational movement of the locking member, the unlocking member can pull the locking member to rotate upward, the locking member loses the locking of the locking pin in the process of rotating upward, thereby facilitating the unloading of the handle, the linkage member connects multiple unlocking members together, the multiple unlocking members can be synchronously pulled by pulling the linkage member, and the template can be quickly disassembled, the second spring and the spring plate can drive the locking member to reset, so as to automatically lock the locking pin next time.

[0023] As a further improvement of the above scheme, a pushing member for pushing the locking pin to move outward is further arranged in the inner cavity of the locking box, and a torsion spring is connected between the pushing member and the locking box;

[0024] A push rod for pushing the pushing member to rotate outward is fixedly arranged on the locking member, and a limiting column for limiting the rotating position of the pushing member is further arranged on the locking box.

[0025] The improved technical effects are that the pushing member has a pushing effect on the locking pin, when the unlocking member is pulled to rotate the locking member to release the locking pin, the pushing member can automatically push the locking pin outward under the driving of the push rod and the torsion spring, thereby saving manpower and facilitating the release of the locking pin, and the limiting column can limit the pushing member to keep the pushing member at a proper position, thereby facilitating the locking of the locking pin next time.

[0026] As a further improvement of the above scheme, a connector is arranged on the top of the handle, and an exhibition board is detachably arranged on the connector.

[0027] The improved technical effects are that the connector on the handle can be sleeved with the reinforcing rod when the handle is pulled to rotate, and the exhibition board can be arranged on the handle after the handle is turned upward to stand, and a warning slogan can be arranged on the exhibition board.

[0043] In order to make the skilled in the art better understand the technical solutions, the technical solutions will be described in detail below in conjunction with examples, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the patent.

[0044] Please refer to Figures 1-7 In a specific embodiment, a construction post-cast strip protection device includes symmetrically arranged templates 10, the middle of the template 10 is provided with a slide post 11, which can be referred to as 1, 2, and 4, the template 10 is symmetrically provided with two templates 10, and the template 10 is in a box shape, the support surface of the template 10 is provided with a containing groove 102 on both sides to facilitate the containing of steel bars, the steel bars pass through the containing groove 102, which can avoid the interference of the steel bars, and the spacing between the containing grooves 102 can be set to multiple standard specifications to adapt to steel cages with different spacings.

[0045] In order to stably install and butt joint between multiple templates 10 when arranging, one end of the template 10 is provided with a jack 20, and the other end is provided with a plug-in table 21 which can be plugged with the jack 20, the plug-in table 21 is specifically slidably arranged on the template 10 along the length direction of the template 10, when two templates 10 are butted, the plug-in table 21 can be inserted into the jack 20 by pulling the plug-in table 21, thereby completing the butt joint and fixation between the two templates 10, and multiple templates 10 are sequentially arranged according to this way when they are butted, so as to sequentially arrange multiple templates 10 to adapt to the length of the post-cast strip.

[0046] The slide post 11 movably sleeves the slide base 12, the slide base 12 is provided with a support 13 which is connected with the template 10 on both sides, specifically, the slide base 12 is rotatably provided with a first connecting seat 22 on both sides, one end of the support 13 is hingedly arranged on the first connecting seat 22, the other end of the support 13 is hingedly provided with a second connecting seat 23, the support 13 is a rod, and two supports 13 are arranged in parallel to enhance the support strength, the second connecting seat 23 and the template 10 are movably connected, and the second connecting seat 23 and the template 10 are connected by a spherical hinge, which can adapt to the rotation requirements at different positions.

[0047] A pressing mechanism is provided above the slide block 12 to drive it to move up and down. When the slide block 12 moves upward under the drive of the pressing mechanism, it drives the templates 10 on both sides to move towards the middle to disassemble the mold. When it moves downward, it drives the templates 10 to separate from the sides and press the templates 10 together.

[0048] The template 10 has a receiving cavity 101 on the side near the sliding column 11 to accommodate the sliding column 11 and the support member 13. The two templates 10 can be interlocked to form a box that is easy to transport. See the attached document for details. Figure 6 As shown, when the device is stored after use, the sliding column 11, sliding seat 12, and support member 13 can be stored in the receiving cavity 101 along the length of the support member 13 through the first connecting seat 22 and the second connecting seat 23. Finally, the template 10 is snapped together to form a box. The entire device does not need to be disassembled, reducing the loss of parts and facilitating storage and transportation.

[0050] A handle 15 is hinged to the sliding sleeve 14, which can be turned by rotating it. A base 26 is fixed to the lower end of the sliding column 11. During installation, the base 26 and the supporting template below are fixed together by bolts. The base 26 mainly serves to fix and support the positioning. A connecting rod 16 is hinged to the base 26. One end of the handle 15 and the connecting rod 16 are hinged to each other. When the handle 15 is turned upward, the sliding sleeve 14 can slide downward under the support of the connecting rod 16, thereby squeezing the slide block 12. The slide block 12 drives the support member 13 to push the template 10 to both sides and tighten it. Conversely, when the handle 15 is turned downward, it can drive the sliding sleeve 14 and the slide block 12 to move upward, thereby disassembling the template 10.

[0051] like Figure 3 , 5 As shown, in a preferred embodiment of the above embodiment, in order to enable the slide block 12 to automatically spring back upward, a first spring 17 is provided between the bottom end of the slide block 12 and the slide column 11. The first spring 17 can reduce the force during demolding when it springs back upward, making it more labor-saving.

[0052] A locking box 18 is fixedly installed on the top of the slide column 11, and a locking component is provided inside the locking box 18 to lock the handle 15.

[0053] The locking box 18 is provided with a slot 181 that communicates with its inner cavity. The slot 181 is designed to taper inward. The side of the handle 15 is provided with a locking pin 151 that can be inserted into the slot 181.

[0054] The locking assembly comprises a locking piece 182 rotatably arranged in the slot 181. The locking piece 182 is a plate-shaped piece. The locking piece 182 is provided with a locking hook portion 183 for clamping the catch pin 151. The locking hook portion 183 is a hook on the locking piece 182. The locking piece 182 is also provided with an inclined portion 184 for facilitating the smooth entry of the catch pin 151 into the inner cavity of the locking box 18. When the catch pin 151 enters the slot 181, the catch pin 151 first contacts the inclined portion 184 and pushes the locking piece 182 to rotate upward until the catch pin 151 is completely clamped between the locking hook portion 183 and the slot 181.

[0055] As a preferred mode of the above embodiment, the locking piece 182 is connected with a second spring 185 and a spring plate 186 for driving the locking piece 182 to reset.

[0056] The inner cavity wall of the locking box 18 is provided with a guide groove for facilitating the movement of the locking piece 182. The length of the guide groove limits the rotation range of the locking piece 182.

[0057] The locking piece 182 is fixedly connected with an unlocking piece 187. In this embodiment, the unlocking piece 187 is a pull rope. The unlocking piece 187 penetrates the locking box 18 upward. When the unlocking piece 187 is pulled, the unlocking piece 187 pulls the locking piece 182 to release the clamping of the catch pin 151. The catch pin 151 can then be pulled out of the slot 181 and turned outward. The unlocking piece 187 is also connected with a linkage 188 for synchronously pulling multiple unlocking pieces 187. The linkage 188 can be a pull rope or a pull rod. The linkage 188 mainly realizes the synchronous pulling control of multiple unlocking pieces 187 and quickly unlocks the catch pin 151 for convenient formwork disassembly.

[0058] As a preferred mode of the above embodiment, the inner cavity of the locking box 18 is also rotatably provided with a pushing piece 189 for pushing the catch pin 151 to move outward. The pushing piece 189 is a push rod. The pushing piece 189 is connected with a torsion spring. The torsion spring drives the pushing piece 189 to push the catch pin 151 outward. The locking piece 182 is fixedly provided with a push rod 1821 for pushing the pushing piece 189 to rotate outward. The push rod 1821 and the pushing piece 189 are spaced apart. When the torsion force of the torsion spring is insufficient, the push rod 1821 pushes the pushing piece 189 to push the catch pin 151 outward when the locking piece 182 is rotated, thereby avoiding the clamping of the catch pin 151 in the slot 181. The locking box 18 is also provided with a limiting column 25 for limiting the rotation position of the pushing piece 189.

[0059] As shown in FIG. 1, Figure 1 , 4As shown in the preferred embodiment of the above example, the top of the handle 15 is provided with a joint; the joint can be sleeved with the force rod when the handle 15 is pulled upward, and the joint is detachably provided with the display board 19, and the display board 19 can be pasted with a propaganda slogan for warning and reminding the construction personnel, so as to avoid damaging the already arranged support mold.
