Description
Technical Field
[0001] The invention relates to the technical field of building construction, and in particular to a slurry leakage prevention device for the root of a template and a construction method thereof. Background Art
[0002] Before pouring concrete wall columns, wooden formwork is generally used to support the formwork. However, due to the unevenness of the concrete slab, there is often a certain gap between the bottom of the formwork and the concrete slab surface. When installing the wall column formwork on site, it is necessary to seal the bottom of the wall column. Currently, the common formwork leakage prevention construction technologies mainly include mortar sealing or wooden strip sealing. The existing mortar sealing requires mixing mortar on site, which greatly delays the sealing time. If wooden strips are used for sealing, there is a problem of loose sealing, and the reinforcement is often not strong, causing misalignment and leakage at the joints at the bottom of the poured wall, which leads to quality problems such as sanding, honeycombing and roughness on the concrete wall. Summary of the Invention

[0012] Furthermore, the clamping member is attached to the bottom of the connecting member, and the thickness of the clamping member gradually decreases from one side of the clamping member close to the notch of the plug-in slot to the other side of the clamping member away from the notch of the plug-in slot.
[0013] Furthermore, locking grooves are formed on the bottom and sides of the connecting piece, and locking flanges are formed on the top and sides of the clamping piece, respectively.

[0035] When in use, the root of the template is detachably inserted into the insertion slot at the top of the connector.
[0036] Clamping members 2 are detachably mounted on opposite sides of the notch of the inserting slot 10 at the bottom of the connector 1. A clamping space is formed between the two clamping members 2.
[0037] The upper portion of the elastic blocking member 3 is detachably inserted into the insertion groove 10 at the bottom of the connector 1. The middle portion of the elastic blocking member 3 is embedded in the clamping space. The lower portion of the elastic blocking member 3 extends to the outside of the clamping space.
[0038] Combine Figure 1 and Figure 3 As shown, after the anti-leakage slurry device at the root of the template 4 is installed on the concrete slab 5, the lower part of the elastic sealing member 3 is squeezed and deformed to fill and seal between the clamping member 2 and the concrete slab 5.
[0039] As a better implementation method, participation Figure 1 As shown in the figure, a through hole 30 is formed in the elastic blocking member 3. The through hole 30 is arranged along the length direction of the elastic blocking member 3.
[0040] In this embodiment, there are multiple through-holes 30 , which are spaced apart in the vertical direction.
[0041] As a preferred embodiment, the cross section of the through channel is diamond-shaped.
[0042] Continue reading Figure 1 and Figure 2 As shown, the groove walls on opposite sides of the insertion groove 10 at the bottom of the connector 1 are formed with limiting ridges. The upper opposite sides of the elastic blocking member 3 are respectively formed with accommodating grooves. The limiting ridges are embedded in the accommodating grooves.
[0043] See Figure 2 As shown, the clamping member 2 is attached to the bottom of the connector 1. The thickness of the clamping member 2 gradually decreases from one side of the clamping member 2 close to the notch of the insertion slot 10 to the other side of the clamping member 2 away from the notch of the insertion slot 10.
[0044] As a preferred embodiment, the bottom and side surfaces of the connector 1 are each formed with a locking groove. The top and side surfaces of the clamping member 2 are each formed with a locking flange 21. The locking flange 21 on the top of the clamping member 2 is inserted into the locking groove on the bottom of the connector 1. The condensed flange on the side of the clamping member 2 is inserted into the locking groove on the side of the connector 1.
[0045] The present invention provides a construction method of a template root anti-leakage slurry device, comprising the following steps:
[0046] S1. Insert the template 4 into the insertion slot 10 on the top of the connector 1 in a detachable manner.
[0047] S2. The upper portion of the elastic blocking member 3 is detachably inserted into the insertion groove 10 at the bottom of the connecting member 1 .
[0048] S3. The two clamping members 2 are detachably installed on the bottom of the connecting member 1, and a clamping space is formed between the two clamping members 2. The middle part of the elastic sealing member 3 is embedded in the clamping space, and the lower part of the elastic sealing member 3 extends to the outside of the clamping space.
[0049] S4. Vertically install the formwork 4 in the installation position so that the anti-leakage slurry device at the root of the formwork 4 is installed on the concrete slab 5, and the lower part of the elastic sealing member 3 is squeezed and deformed to fill and seal between the clamping member 2 and the concrete slab 5.
[0050] The present invention's leak-proof slurry device for the base of a formwork is divided into three parts: an H-shaped connector for leak-proof slurry, an elastic sealing member with a cavity, and a clamping member. The H-shaped connector is constructed in an H-shape, with an upper slot for direct insertion of the wooden formwork. The slot directly holds the formwork in place, and a non-slip rubber pad is located at the top of the slot to ensure reliable connection between the device and the formwork. The lower slot of the H-shaped connector is for insertion of the elastic sealing member, and a non-slip rubber pad is also located at the bottom of the H-shaped connector to prevent the elastic sealing member from sliding.
[0051] The elastic seal's upper portion also provides a secure fit, ensuring a tight connection between it and the retaining ribs of the connector, preventing displacement. The internal cavity of the elastic seal facilitates deformation under load, improving the fit between the device and the seal, effectively preventing grouting. If the elastic seal wears out, it can be replaced.
