Description

Technical Field

[0001] This utility model belongs to the field of concrete formwork technology, specifically relating to a head formwork for preventing grout leakage at the ends of concrete beams. Background Technology

[0002] Construction formwork is a temporary support structure. By fixing the formwork on both sides, a concrete pouring cavity is formed. After the concrete solidifies in the cavity, it forms a column or wall. Due to the small spacing of the reinforcing bars in concrete upturned beams, leakage often occurs at the ends due to incomplete sealing, resulting in loose concrete pouring, honeycomb, voids, and other quality defects, thus reducing the safety and reliability of the beam. To address this, designers have researched various beam end formworks. For example, Chinese utility model patent application number CN201120463762.7 discloses a precast beam end formwork, specifically comprising a first formwork assembly, a second formwork assembly, a third formwork assembly, a fourth formwork assembly, a fifth formwork assembly, and a sixth formwork assembly connected sequentially from top to bottom. Several reinforcing bar perforations are provided between the first and second formwork assemblies, between the fourth and fifth formwork assemblies, and between the fifth and sixth formwork assemblies. Embedded part holes are provided on the second formwork assembly. The precast beam end formwork has a simple structure, is easy to assemble, and is connected to each other in a movable manner, making the height of the precast beam end formwork adjustable and convenient to use.

[0003] However, the spacing and dimensions of the exposed reinforcing bars at the ends vary depending on the working conditions. The above-mentioned templates cannot meet the requirements for end sealing under other working conditions. This leads to the need to use various templates or relatively primitive self-made wooden boards for sealing under different working conditions. Moreover, there is still the problem of grout leakage caused by incomplete sealing. This results in the concrete pouring of the structural beams being not dense, with quality defects such as honeycomb and voids, which reduces the safety and reliability of the structural beams. Summary of the Invention

[0004] Based on this, this application provides a sealing template for preventing grout leakage at the ends of concrete beams. This addresses the issue that the spacing and dimensions of exposed reinforcing bars at the ends vary depending on different working conditions. Using the aforementioned templates cannot meet the end sealing requirements under other working conditions, leading to the need to use multiple templates or relatively primitive self-made wooden boards for sealing under different working conditions. Even then, the sealing is not tight, resulting in grout leakage. This leads to the concrete pouring of the structural beam being not dense, resulting in quality defects such as honeycomb and voids, which reduces the safety and reliability of the structural beam.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] A type of end cap formwork for preventing grout leakage at the ends of concrete beams, comprising:

[0007] The system comprises a vertical component, a horizontal component, an auxiliary component, and a fastener. The vertical component includes a first vertical plate and a second vertical plate, both of which are provided with a first sliding groove. The horizontal component includes a first horizontal plate, a second horizontal plate, and a third horizontal plate. The first horizontal plate and the second horizontal plate are arranged opposite each other, and the third horizontal plate is disposed on one side of either the first or the second horizontal plate. Both ends of the first, second, and third horizontal plates are detachably disposed within the first sliding groove and slide in cooperation with it. Both the first and second horizontal plates are provided with a second sliding groove, the extension direction of which is perpendicular to the extension direction of the first sliding groove.

The end of the first snap-fit ​​block away from the second sliding groove has a slot for snapping in reinforcing bars. The fastener is detachably mounted on the first vertical plate, the second vertical plate, the first horizontal plate, and the second horizontal plate.

[0008] Preferably, a plurality of the first snap-fit ​​blocks and the second snap-fit ​​blocks are provided, and the first snap-fit ​​blocks on the first horizontal plate and the first snap-fit ​​blocks on the second horizontal plate are respectively snap-fitted on opposite sides of the vertical direction of the reinforcing bar; the second snap-fit ​​blocks on the first horizontal plate are connected to the second snap-fit ​​blocks on the second horizontal plate, and the end of the second snap-fit ​​block away from the second sliding groove is a plane.

[0009] Preferably, the fixing member includes two first fixing plates, which respectively cover the two ends of the first horizontal plate, the second horizontal plate and the third horizontal plate, and are detachably connected to the first vertical plate and the second vertical plate, for fixing the first horizontal plate, the second horizontal plate and the third horizontal plate.

[0010] Preferably, the first fixing plate has a first through hole at both ends, and the first vertical plate and the second vertical plate have a first threaded hole at both ends, and the first through hole is bolted to the first threaded hole.

[0011] Preferably, the fastener includes at least two second fixing plates, which cover the first snap-fit ​​block and the second snap-fit ​​block and are detachably connected to the first horizontal plate and the second horizontal plate, respectively, for fixing the first snap-fit ​​block and the second snap-fit ​​block.

[0012] Preferably, the second fixing plate has second through holes at both ends, and the first and second horizontal plates have second threaded holes at both ends, with the second through holes and the second threaded holes being bolted together.

[0013] Preferably, the first horizontal plate includes a sliding part, a covering part, and a fixing part. The fixing part is provided with a second sliding groove, and the second threaded holes are distributed at both ends of the second sliding groove. The sliding part is disposed at both ends of the fixing part, extends into the first sliding groove, and is capable of sliding along the extension direction of the first sliding groove. The covering part is disposed at the end of the sliding part away from the fixing part, and the covering part covers the first vertical plate and the second vertical plate respectively.

[0014] Preferably, the first fixing plate covers the fixing part and is detachably connected to the first vertical plate.

[0015] Preferably, the first snap-fit ​​block includes an embedding part, a clamping part, and a supporting part. The embedding part is slidably connected in the second groove and can slide along the extension direction of the second groove. The clamping part is disposed at one end of the embedding part, and the snap-fit ​​groove is located at the end of the clamping part away from the embedding part.

[0017] The technical solution adopted in this application can achieve the following beneficial effects:

[0018] 1. By replacing the first snap-fit ​​block with a different size slot, it is suitable for sealing the ends of various steel bars. Furthermore, through a detachable and sliding connection, the first snap-fit ​​block can slide along the second groove, thereby adjusting the position of the slot to meet the requirements of different transverse spacing of exposed steel bars at the ends.

[0019] 2. By making the first and second horizontal plates detachable and able to slide along the first groove, the problem of different vertical spacing of exposed steel bars, which leads to a limited range of applications, is solved. At the same time, by adjusting the width of the first and second horizontal plates according to the vertical spacing of exposed steel bars, the problem of different vertical spacing of exposed steel bars, incomplete sealing, and quality defects such as honeycomb and holes are solved, which reduces the safety and reliability of the structural beam.

[0020] 3. By using fasteners to limit and fix vertical and horizontal components, the problem of individual parts being easy to fall off or be lost is solved. At the same time, by using a multi-part method, parts that are difficult to remove can be removed by removing the first or second locking block, making removal easier and solving the problem of large sealing areas, difficult removal, and easy deformation of tooling due to violent construction.

[0031] Please see Figures 1 to 6 This application provides a sealing template for preventing grout leakage at the ends of concrete beams, comprising a vertical component 100, a horizontal component 200, an auxiliary component 300, and a fixing member 400. The vertical component 100 includes a first vertical plate 110 and a second vertical plate 120, both of which are provided with a first sliding groove 121. The horizontal component 200 includes a first horizontal plate 210, a second horizontal plate 220, and a third horizontal plate 230. The first horizontal plate 210 and the second horizontal plate 220 are arranged opposite to each other, and the third horizontal plate 230 is disposed on one side of either the first horizontal plate 210 or the second horizontal plate 220. Both ends of the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 are detachably disposed within the first sliding groove 121 and slide in cooperation with the first sliding groove 121. The first horizontal plate 210 and the second horizontal plate 220 are detachably disposed within the first sliding groove 121. Each of the 220 sections is provided with a second sliding groove 221, the extension direction of the second sliding groove 221 being perpendicular to the extension direction of the first sliding groove 121; the auxiliary component 300 includes a first snap-fit ​​block 310 and a second snap-fit ​​block 320, the first snap-fit ​​block 310 and the second snap-fit ​​block 320 being detachably disposed in the second sliding groove 221 and slidingly engaged with the second sliding groove 221; a slot 311 is provided at the end of the first snap-fit ​​block 310 away from the second sliding groove 221, the slot 311 being used to snap-fit ​​the reinforcing bar; the fixing member 400 is detachably covered on the first vertical plate 110, the second vertical plate 120, the first horizontal plate 210 and the second horizontal plate 220, and is used to fix the first horizontal plate 210, the second horizontal plate 220, the third horizontal plate 230 and the first snap-fit ​​block 310 and the second snap-fit ​​block 320.

[0032] Specifically, the first vertical plate 110 and the second vertical plate 120 in the vertical assembly 100 have the same structure and several length options, selected according to the end size. Both the first vertical plate 110 and the second vertical plate 120 are provided with a first sliding groove 121, which is parallel to the length direction of the first vertical plate 110. The first vertical plate 110 and the second vertical plate 120 are located on both sides of the end and are detachably connected to the templates on both sides using bolts, connecting plates, etc. The first horizontal plate 210 and the second horizontal plate 220 have the same structure and are located between the first vertical plate 110 and the second vertical plate 120. Both the first horizontal plate 210 and the second horizontal plate 220 are provided with a second sliding groove 221, which is parallel to the length direction of the first horizontal plate 210 and perpendicular to the first sliding groove 121. The third horizontal plate 230 is also located between the first vertical plate 110 and the second vertical plate 120. The first horizontal plate 210 is located below the second horizontal plate 220 or above the first horizontal plate 210. The third horizontal plate 230 is also provided with several widths, selected according to the spacing of the exposed steel bars at the ends. The widths of the first horizontal plate 210 and the second horizontal plate 220 are at least suitable for the minimum steel bar spacing. One end of the first snap-fit ​​block 310 is provided with a slot 311, and there are several types of first snap-fit ​​blocks 310. The slots 311 on each type of first snap-fit ​​block 310 are different and correspond to steel bars of different sizes. The structure of the second snap-fit ​​block 320 is similar to that of the first snap-fit ​​block 310, but it is not provided with a slot 311. The two first snap-fit ​​blocks 310 provided on the first horizontal plate 210 and the second horizontal plate 220 are arranged opposite each other. When the two first snap-fit ​​blocks 310 are in contact, the two slots 311 are opposite each other and form round holes that clamp the ends of the steel bars. Similarly, when the second snap-fit ​​blocks 320 are in contact with each other, they form a closed whole.

[0033] The fastener 400 uses, but is not limited to, bolts, clips, or other detachable methods to limit and fix the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 to the first vertical plate 110 and the second vertical plate 120, while limiting and fixing the first snap-fit ​​block 310 and the second snap-fit ​​block 320 to the first horizontal plate 210 and the second horizontal plate 220.

[0034] Furthermore, based on the drawings and actual site dimensions, the construction personnel selected the dimensions of the first vertical plate 110 and the second vertical plate 120 (selected according to the end height), as well as the dimensions of the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 (selected according to the end width). Simultaneously, they selected the first locking block 310 corresponding to the slot 311 (selected according to the rebar diameter), and arranged the first locking block 310 and the second locking block 320 according to the dimensions in the drawings. They then installed them respectively in the first sliding groove 121 on the first horizontal plate 210 and the second sliding groove 221 on the second horizontal plate 220, with the first locking block 310 on the first horizontal plate 210 and the first locking block 310 on the second horizontal plate 220 facing each other. Similarly, the first locking block 310 on the first horizontal plate 210 and the first locking block 310 on the second horizontal plate 220 are then installed in the same way. The second snap-fit ​​block 320 on the first horizontal plate 210 is opposite to the second snap-fit ​​block 320 on the second horizontal plate 220; after arrangement and installation, the fastener 400 is used to limit and fix it; according to the dimensions of the end on the drawing, the number of the first horizontal plate 210, the second horizontal plate 220 and the third horizontal plate 230 are selected (selected according to the number of rows of steel bars, spacing, etc.); after selection, the first vertical plate 110 and the second vertical plate 120 are connected to the templates on both sides by bolts, pull rings and other detachable connections, and the first horizontal plate 210, the second horizontal plate 220 and the third horizontal plate 230 are snapped into the first sliding groove 121 in sequence, and the fastener 400 is used to limit and fix it to the first vertical plate 110 and the second vertical plate 120. After installation, the end is reinforced by diagonal supports, ropes and other methods.

[0035] Furthermore, when dismantling after pouring, only the fasteners 400 fixed to the first vertical plate 110 and the second vertical plate 120 need to be removed, and then the first horizontal plate 210, the second horizontal plate 220 and the third horizontal plate 230 can be removed respectively; for the next end of the same type, the removed first vertical plate 110, second vertical plate 120, first horizontal plate 210, second horizontal plate 220 and third horizontal plate 230 can be polished and coated with release agent before being directly installed and used.

[0036] The technical solution for the end cap formwork used in this application to prevent grout leakage at the ends of concrete beams can achieve the following beneficial effects:

[0037] 1. By replacing the first snap-fit ​​block 310 with a different size slot 311, it is suitable for sealing the ends of various steel bars. And through the detachable and sliding connection, the first snap-fit ​​block 310 can slide along the second slide groove 221, thereby adjusting the position of the slot 311 to meet the requirements of different transverse spacing of exposed steel bars at the ends.

[0038] 2. By making the first and second horizontal plates detachable and able to slide along the first groove 121, the problem of different vertical spacing of exposed steel bars, which leads to a limited range of applications, is solved. At the same time, by adjusting the width of the first horizontal plate 210 and the second horizontal plate 220 according to the vertical spacing of exposed steel bars, the problem of different vertical spacing of exposed steel bars, incomplete sealing, and quality defects such as honeycomb and holes are solved, which reduces the safety and reliability of the structural beam.

[0039] 3. By using fasteners 400 to limit and fix the vertical component 100 and the horizontal component 200, the problem of many individual parts being easy to fall off or be lost is solved. At the same time, by using a multi-part method, parts that are difficult to remove can be removed by removing the first snap-fit ​​block 310 or the second snap-fit ​​block 320, making the removal easier and solving the problem of large sealing areas, difficult removal, and easy deformation of tooling due to violent construction.

[0040] In the above scheme, several first snap-fit ​​blocks 310 and second snap-fit ​​blocks 320 are provided, and the first snap-fit ​​blocks 310 on the first horizontal plate 210 and the first snap-fit ​​blocks 310 on the second horizontal plate 220 are respectively snapped onto the opposite sides of the vertical direction of the reinforcing bar; the second snap-fit ​​blocks 320 on the first horizontal plate 210 and the second snap-fit ​​blocks 320 on the second horizontal plate 220 are connected in cooperation, and the end of the second snap-fit ​​block 320 away from the second sliding groove 221 is a plane. The first snap-fit ​​block 310 and the second snap-fit ​​block 320 are arranged in a combination (the order is based on the distance of the exposed steel bars), and the total length of the first snap-fit ​​block 310 and the second snap-fit ​​block 320 after arrangement is the same as the length of the first slide groove 121. The ends of the first snap-fit ​​block 310 and the second snap-fit ​​block 320 away from the first slide groove 121 are flush with one side of the first horizontal plate 210 and the second horizontal plate 220. By sliding the first horizontal plate 210 and the second horizontal plate 220 in the first slide groove 121, the opposite ends of the first horizontal plate 210 and the second horizontal plate 220 come into contact. At this time, the snap-fit ​​grooves 311 on the opposite first snap-fit ​​blocks 310 come into contact to form a round hole. Similarly, the opposite second snap-fit ​​blocks 320 come into contact to form a sealed whole. By sliding the first horizontal plate 210 and the second horizontal plate 220 along the first groove 121, the distance between the two relative first locking blocks 310 (second locking blocks 320) is changed. First, the first horizontal plate 210 is placed above the reinforcing bar, and the first horizontal plate 210 is slid downward so that the locking groove 311 on the first locking block 310 is locked in the upper part of the reinforcing bar. Then, the second horizontal plate 220 is placed in the first groove 121 and located below the reinforcing bar. By sliding the second horizontal bar upward, the locking groove 311 of the first locking block 310 on the second horizontal bar is locked in the lower part of the reinforcing bar. The operation is simpler and the sealing effect is better.

[0041] In a preferred embodiment of this application, the fastener 400 includes two first fixing plates 410. The two first fixing plates 410 respectively cover the two ends of the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230, and are detachably connected to the first vertical plate 110 and the second vertical plate 120, respectively, for fixing the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230. Two first fixing plates 410 are provided. The length of the two first fixing plates 410 is less than the length of the first vertical plate 110 and greater than the length of the first sliding groove 121. The two ends of the fixing plates are fixed to the first vertical plate 110 by means of buckles, wires, etc. The first fixing plates 410 are provided with anti-slip pads of different materials to increase friction. By covering the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230, the arranged first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 are pressed onto the first vertical plate 110 and the second vertical plate 120, thereby increasing their ultimate load-bearing capacity.

[0042] In the above scheme, in order to increase the firmness and convenience of fixing, the first fixing plate 410 is provided with first through holes 411 at both ends, and the first vertical plate 110 and the second vertical plate 120 are provided with first threaded holes 122 at both ends, and the first through holes 411 and the first threaded holes 122 are bolted together.

[0043] The first threaded holes 122 are located on both sides of the first slide groove 121, and the first through holes 411 are located on both sides of the first fixing plate 410. The distance between the two first through holes 411 is the same as the distance between the two first threaded holes 122. The first fixing plate 410 is placed over the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230, with the first through holes 411 coinciding with the first threaded holes 122. A bolt is used, passing through the first through hole 411 and rotating into the first threaded hole 122 (the length of the bolt is not greater than the distance between the side of the first fixing plate 410 away from the first vertical plate 110 and the bottom of the first threaded hole 122, ensuring that when one end of the bolt is close to one side of the first fixing plate 410, the other end of the bolt is not completely in contact with the bottom of the first threaded hole 122), so that the first fixing plate 410 tightly covers the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230. Using bolt threaded holes makes installation and removal more convenient and provides better ultimate compressive strength.

[0044] In another preferred embodiment of this application, the fastener 400 includes at least two second fixing plates 420. The second fixing plates 420 cover the first snap-fit ​​block 310 and the second snap-fit ​​block 320, and are detachably connected to the first horizontal plate 210 and the second horizontal plate 220, respectively, for fixing the first snap-fit ​​block 310 and the second snap-fit ​​block 320. The second fixing plates 420 have second through holes 421 at both ends, and the first horizontal plate 210 and the second horizontal plate 220 each have second threaded holes 222 at both ends. The second through holes 421 are bolted to the second threaded holes 222.

[0045] The second fixing plate 420 has the same structure as the first fixing plate 410, and the length of the second fixing plate 420 is determined according to the length of the first horizontal plate 210 and the second sliding groove 221. Each length type of the first horizontal plate 210 corresponds to one second fixing plate 420. The second fixing plate 420 facilitates fixing and disassembly while increasing the firmness of the first horizontal plate 210 and the second horizontal plate 220, reducing their deformation rate, and extending their maintenance cycle.

[0046] Based on the above scheme, the first horizontal plate 210 includes a sliding part, a covering part, and a fixing part. The fixing part is provided with a second sliding groove 221, and the second threaded holes 222 are distributed at both ends of the second sliding groove 221. The sliding part is disposed at both ends of the fixing part, extends into the first sliding groove 121, and is capable of sliding along the extending direction of the first sliding groove 121. The covering part is disposed at the end of the sliding part away from the fixing part, and the covering part covers the first vertical plate 110 and the second vertical plate 120 respectively. The first fixing plate 410 covers the fixing part and is detachably connected to the first vertical plate 110.

[0047] The sliding part and the cover part of the first horizontal plate 210 are T-shaped. The sliding part is embedded in the first sliding groove 121, and the depth and width dimensions of the sliding part are the same as the depth and width dimensions of the first sliding groove 121. It can slide along the extension direction of the first sliding groove 121. The first fixing plate 410 covers the cover part. By providing the sliding part and the cover part, the contact area between the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 and the first vertical plate 110 and the second vertical plate 120 is increased. Okay, and the length of the arrangement is the same as the length of the first chute 121, which restricts the position of the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230. The first fixing plate 410 covers the covering part, restricting its position and solving the problem that the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230 will fall downwards due to the tilt of the first vertical plate 110 and the second vertical plate 120. At the same time, it solves the problem that the concrete expands outward and causes it to detach from the first vertical plate 110 and the second vertical plate 120. Furthermore, the number of first threaded holes 122 and the width of the first fixing plate 410 can be increased to increase its contact area with the first horizontal plate 210, the second horizontal plate 220, and the third horizontal plate 230, thereby increasing its compressive strength.

[0048] Similarly, the first fixing plate 410 and the second fixing plate 420 have the same structure and are also divided into a T-shaped sliding part, a covering part and a fixing part, which will not be described in detail here.

[0049] In another embodiment of this application, the first snap-fit ​​block 310 includes an embedding portion, a clamping portion, and a supporting portion. The embedding portion is slidably connected within the second slide groove 221 and is slidable along the extending direction of the second slide groove 221. The clamping portion is disposed at one end of the embedding portion, and the snap-fit ​​groove 311 is located at the end of the clamping portion away from the embedding portion. The supporting portion is disposed at the end of the embedding portion away from the clamping portion and covers the first horizontal plate 210. The second fixing plate 420 covers the supporting portion and is detachably connected to the first horizontal plate 210.

[0050] The embedded part and the support part are also T-shaped. The height and width of the embedded part are the same as the depth and width of the second slide groove 221, and it can slide along the extension direction of the second slide groove 221. The second fixing plate 420 covers the support part. By setting the embedded part and the support part, the contact area between the first locking block 310, the second locking block 320 and the first horizontal plate 210 and the second horizontal plate 220 is increased. By arranging them in a way that is the same as the length of the second slide groove 221, the position of the first locking block 310 and the second locking block 320 is restricted. The position is restricted by the second fixing plate 420 covering the support part. This solves the problem that the first locking block 310 and the second locking block 320 fall downwards due to the tilt of the first vertical plate 110 and the second vertical plate 120. At the same time, it solves the problem that the concrete expands outward and causes it to detach from the first horizontal plate 210 and the second horizontal plate 220. Furthermore, the number of second threaded holes 222 and the width of the second fixing plate 420 can be increased to increase the contact area between the second fixing plate 420 and the first locking block 310 and the second locking block 320, thereby increasing its resistance to compression.

[0051] The first snap-fit ​​block 310 and the second snap-fit ​​block 320 have the same structure. The only difference is that the clamping part of the first snap-fit ​​block 310 is provided with a slot 311, while the clamping part of the second snap-fit ​​block 320 is a plane. The slot 311 of the first snap-fit ​​block 310 is used to snap-fit ​​the reinforcing bar, and the clamping parts of the two opposite second snap-fit ​​blocks 320 contact each other to form a whole.

[0052] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
