Abstract
Description
Technical Field
[0001] This application relates to the field of materials and equipment for formwork engineering in building construction, and specifically relates to a wall and column bottom positioning and anti-leakage mortar system. Background Art
[0002] In the construction of cast-in-place concrete walls and columns, it is necessary to first build the casting formwork, and before building the casting formwork, it is necessary to first complete the construction of the bottom positioning and anti-leakage mortar system. However, in the construction of the bottom positioning and anti-leakage mortar system, the existing problems are as follows: (1) In actual measurement and so-called plaster-free projects, waste steel bars are cut into lengths basically the same as the width of the wall surface for large-area use, and are welded to the vertical steel bars of the wall and column for large-area positioning. For the inner and outer corners, cross-shaped steel bars are welded to the main load-bearing steel bars of the wall and column for positioning. Due to errors during steel bar cutting, errors caused by the sharp inclined surface generated during cutting piercing into the formwork after locking and reinforcement, and errors during welding when aligning the steel bars with the construction line of the wall and column, etc., it is very easy to generate an error of 3-8 mm between the large-area positioning steel bars and the cross-shaped positioning steel bars at the inner and outer corners. As a result, it is very difficult to control the wall surface flatness and verticality within 5 mm with a qualification rate of 95%. Moreover, since the positioning steel bars are welded to the vertical steel bars of the wall and column, especially on the vertical main steel bars at the inner and outer corners, the welding damages the load-bearing vertical steel bars. In addition, after the positioning steel bars are exposed outside the wall and column concrete and corrode for a long time, the bearing capacity of the vertical load-bearing steel bars of the wall and column decreases rapidly, which will pose potential safety risks to the building structure after a certain period of time; (2) Currently on the construction site, holes are commonly drilled on the ground close to the inner side of the construction line of the wall and column, and then short steel bars about 80 mm long and slightly larger than the holes are driven into the holes. Due to deviations in the drilling position and the driving angle of the short steel bars, etc., the deviation between the wall and column positioning steel bars is about 5 mm, which is extremely non-standard; (3) Before pouring, most of the mortar is filled into the inner side of the bottom of the formwork for edge sealing to prevent the concrete from leaking out through the gap between the pressing foot and the ground during the pouring process. This not only makes the operation troublesome, but also the mortar at the bottom of the sealed wall is very easy to be stuffed into the wall and column construction line in a jagged shape with a protrusion of 5-30 mm, posing a potential safety risk to the load-bearing capacity of the wall and column, and also increasing construction costs, material waste, and carbon emissions, etc.; (4) Before pouring, some use wooden squares to block the bottom of the wall and column formwork, but it can only prevent the concrete from leaking out and reduce the leakage of mortar. Moreover, after the concrete filling the gap between the bottom of the wall and column formwork and the ground solidifies, it needs to be chiseled, resulting in material waste and being time-consuming, laborious, and costly.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] Embodiment 1
[0032] As Figure 1 shown, a wall-column bottom limiting and anti-leakage slurry system includes an external corner positioning member 300 and / or an internal corner positioning member 400 which are arranged on the ground and at the internal corners of the wall and column according to the shapes of the walls and columns to be cast, and also includes a pressing foot part 100 which is arranged on the ground and along the shapes of the walls and columns to be cast on the outer sides of the edges of the walls and columns, and a positioning bar 200 which is arranged on the ground and between two parallel pressing foot parts 100.
[0033] The external corner positioning member is as Figure 5 shown, mainly composed of an L-shaped fixing piece and a positioning piece which is vertically arranged on the upper side of the fixing piece and is L-shaped; the positioning piece is arranged along the outer right-angle side of the upper side surface of the fixing piece, and a plurality of fixing holes for fixing the fixing piece on the ground are also arranged on the fixing piece.
[0034] The internal corner positioning member is as Figure 6 shown, mainly composed of an L-shaped fixing piece and a positioning piece which is vertically arranged on the upper side of the fixing piece and is L-shaped; the positioning piece is arranged along the inner right-angle side of the upper side surface of the fixing piece, and a plurality of fixing holes for fixing the fixing piece on the ground are also arranged on the fixing piece.
[0035] As Figure 2 shown, the pressing foot part 100 is composed of an elastic strip 101 and an L-shaped anti-leakage slurry pressing foot 104 arranged above the elastic strip 101; an L-shaped pressing foot 102 is also arranged on the L-shaped anti-leakage slurry pressing foot 104, and a strengthening piece 103 which is integrally fixed with the L-shaped pressing foot 102 is also arranged on the L-shaped pressing foot 102.
[0036] The elastic strip 101 is an elastic EPE strip or a sponge strip.
[0037] The elastic strip is made of elastic material, not limited to the above-mentioned pearl cotton strip or sponge strip, for example, it can also be a non-woven fabric strip, rubber strip, or even plastic strip with a certain thickness. Its main function is to fill the gap between the L-shaped anti-leakage slurry pressure foot and the ground. When the upper part is subjected to greater pressure, the elastic strip can be effectively pressed against the ground, thereby preventing concrete from flowing out of the gap between the L-shaped pressure foot and the ground during pouring, thereby better ensuring the strength of the wall and column after pouring.
[0038] The bottom surface of the L-shaped anti-leakage grout presser foot 104 is pressed on the elastic strip 101, the side surface of the L-shaped anti-leakage grout presser foot 104 is perpendicular to the bottom surface, and the side surface of the L-shaped anti-leakage grout presser foot 104 is located at one side edge of the bottom surface close to the positioning rib 200.
[0039] Since the inner side of the L-shaped anti-leakage slurry pressure foot needs to be set up with wall and column formwork during subsequent construction, a side surface is vertically set on the inner side of the L-shaped anti-leakage slurry pressure foot. The main function of this side surface is to rest against the bottom of the inner side surface of the wall and column formwork to ensure the stability of the wall and column formwork.
[0040] The edge of the bottom surface of the L-shaped anti-leakage grout presser foot 104 facing away from the positioning rib 200 is flush with the outer edge of the elastic strip 101 , and the width of the L-shaped anti-leakage grout presser foot 104 is less than or equal to the width of the elastic strip 101 .
[0041] The width of the elastic strip is greater than the width of the L-shaped anti-leakage slurry pressure foot, so it can ensure that the wall and column formwork during subsequent construction can be located on the upper side thereof. During pouring construction, it can also ensure that after the elastic strip is compressed by concrete, the pouring range of concrete will not extend to directly below the wall and column formwork, ensuring that after the wall and column are formed, their outer lower edges will not have outward protrusions, reducing the difficulty of subsequent processing.
[0042] The two adjacent side surfaces of the reinforcing sheet 103 are respectively fixed on the bottom surface and the side surface of the L-shaped presser foot 102, and the rear side of the reinforcing sheet 103 extends outward from the bottom surface of the L-shaped presser foot 102 and then extends downward from the L-shaped presser foot 102; the downward extending length of the reinforcing sheet 103 is greater than the total thickness of the bottom surface of the L-shaped presser foot 102 and the bottom surface of the L-shaped anti-leakage slurry presser foot 104.
[0043] The reinforcing sheet can not only improve the force-bearing capacity of the side of the L-shaped presser foot, but also effectively prevent the elastic strip from moving outward under the pressure of concrete, thereby better ensuring the actual use effect of the product.
[0044] like Figure 4 As shown, the positioning rib 200 is composed of a reinforcement bar 201 , a head support piece 202 arranged at the front end of the reinforcement bar 201 , and a tail support piece 203 arranged at the rear end of the reinforcement bar 201 .
[0045] The head support piece 202 and the tail support piece 203 are in an "L" shape. The two ends of the steel bar 201 are respectively fixed parallelly by welding on the outer sides of the sides of the head support piece 202 and the outer sides of the sides of the tail support piece 203. The steel bar 201 is simultaneously parallel to the bottom edges of the head support piece 202 and the tail support piece 203.
[0046] Since the steel bar is arranged parallel to the side of the head support piece and the side of the tail support piece, when welding the steel bar to the side of the head support piece and the side of the tail support piece, the contact area between the steel bar and the side of the head support piece and the side of the tail support piece can be adjusted according to actual needs. Therefore, when the lengths of the cut steel bars are different, the overall length of the product can still be controlled by adjusting the welding length, which can better ensure the consistency of the product length and further improve the use effect of the product.
[0047] The head support piece 202 and the tail support piece 203 are located on the same side of the steel bar 201.
[0048] In order to improve the service life of the product and ensure the safety and stability of the project quality, each of the above components can be treated by galvanizing, painting, soaking in an antirust liquid, etc., so that a layer of antirust coating can be covered on the surface of each component, further ensuring the antirust effect of the product and effectively avoiding the impact on the safety of the concrete structure caused by the corrosion of the product.
[0049] Embodiment 2
[0050] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is only that the head support piece 202 and the tail support piece 203 are located on both sides of the steel bar 201.
[0051] It should be noted that all the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.
[0052] In addition, the above specific embodiments are exemplary. Those skilled in the art can come up with various solutions inspired by the disclosed content of the present invention, and these solutions also belong to the disclosed scope of the present invention and fall within the protection scope of the present invention.
