Description

Technical Field

[0001] The invention relates to the technical field of building templates, in particular to a modular house building template system. Background Art

[0002] The information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] At present, with the vigorous development of the construction industry, the modular building formwork system has become the mainstream formwork system in construction projects. It has many advantages such as good concrete molding quality, convenient disassembly and assembly, and high turnover rate, and has been widely recognized in the industry. After the concrete wall is poured, the modular building formwork system needs to be disassembled and recycled. The industry knows that how to complete the formwork removal operation efficiently and safely without damaging the formwork and wall is an important issue to ensure project quality, construction progress and construction safety.

[0004] Traditional building formwork systems usually do not have a safe and efficient formwork removal structure, and the disassembly operation is inconvenient. When removing the formwork, it is often necessary to use formwork removal tools such as formwork removal hammers and formwork removal rods. Construction workers first use formwork removal hammers to hammer the disassembly gaps, and then use formwork removal rods to pry the formwork disassembly gaps, and finally separate the formwork from the wall. In engineering practice, the above-mentioned formwork removal operation method often requires construction workers to have certain operating skills, and has high requirements on the personal ability of construction workers. In addition, due to the work experience and work responsibility of construction workers, it is impossible to form a standard formwork removal operation procedure, resulting in the inability to effectively control the construction quality. It is easy for construction workers to perform irregular formwork removal operations such as brutal hammering and rough prying. The labor intensity is high, the operation efficiency is low, and it is very easy to cause damage to the formwork, which reduces the flatness of the formwork and affects the quality of the wall product. When removing the formwork, the formwork falls randomly, which poses a great safety hazard and is easy to damage the concrete wall surface. It further aggravates the degree of formwork damage, reduces the recycling rate of aluminum formwork, and increases the recycling and processing costs. Summary of the invention

[0005] Based on this, it is necessary to provide a modular house building formwork system to address the problems of low formwork disassembly efficiency, high labor intensity, easy damage to formwork and walls, and high formwork recycling cost in the current building formwork system in engineering practice.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A combined housing building formwork system includes formwork components for the shaped pouring of concrete walls. The formwork components include vertical plates arranged corresponding to the facades of the pre-poured concrete walls. The bottom of the vertical plates is connected by side screws to bottom angle baffles arranged corresponding to the bottom corners of the pre-poured concrete walls. At the top of the vertical plates, inside corner plates are arranged corresponding to the inside corners of the pre-poured concrete walls. A fixing component is arranged corresponding to the formwork components for the support and fixation of the formwork components. It also includes a formwork removal structure for the removal of the formwork components. The formwork removal structure includes wedge-shaped strip ribs arranged corresponding to the vertical plates. An inclined plate is arranged at the bottom of the vertical plate. The bottom end of the inclined plate is connected to a bottom plate. The bottom angle baffle includes a vertical plate and a horizontal plate. The wedge-shaped strip ribs are accommodated in the accommodation space formed by enclosing the inclined plate, the vertical plate, the horizontal plate and the bottom plate. A first bevel angle is arranged at the upper end of the wedge-shaped strip ribs, and the first bevel angle is arranged between the inclined plate and the vertical plate of the bottom angle baffle. The slope of the inclined plate is set corresponding to the first bevel angle of the wedge-shaped strip ribs, so that both sides of the first bevel angle of the wedge-shaped strip ribs are respectively attached to the inclined plate and the vertical plate. A U-shaped through hole is opened on the bottom plate. A threaded hole is coaxially opened at the tail end of the wedge-shaped strip ribs corresponding to the U-shaped through hole. A vertical screw rod passes through the threaded hole of the wedge-shaped strip ribs and passes through the U-shaped through hole of the bottom plate. The lower end of the vertical screw rod is a flat structure, and a moving space for the upward jacking of the wedge-shaped strip ribs is reserved in the accommodation space formed by enclosing the inclined plate, the vertical plate, the horizontal plate and the bottom plate.

[0008] Optionally, a second bevel angle is arranged at the tail end of the wedge-shaped strip ribs. The inclined surface of the second bevel angle is parallel to the inclined plate. The bottom plate is provided with a wedge-shaped surface corresponding to the second bevel angle, and the slope of the wedge-shaped surface is equal to the slope of the inclined plate.

[0009] Optionally, a rubber bottom stop is arranged at the lower end of the bottom angle baffle to improve the sealing performance of the bottom angle baffle. The bottom end of the vertical screw rod passes through the horizontal plate of the bottom angle baffle, so that the bottom end of the vertical screw rod presses tightly on the rubber bottom stop. A pressure strip is arranged between the rubber bottom stop and the bottom end of the vertical screw rod to ensure that the pressing force in the length direction of the rubber bottom stop tends to be consistent.

[0010] Optionally, a top plate is arranged at the top of the vertical plate. An uneven assembly structure is arranged on the outer side of the top plate corresponding to the lower end surface of the inside corner plate. The uneven assembly structure includes a positioning groove opened on the top plate. A positioning rib is arranged on the lower end surface of the inside corner plate corresponding to the positioning groove. The cross sections of the positioning groove and the positioning rib are trapezoidal structures in an inverted shape.

[0011] Optionally, the lower end surface of the wedge-shaped strip ribs, the upper end surface of the horizontal plate and the lower end surface of the bottom plate are correspondingly provided with arc surfaces with the same radian. The lower ends of the wedge-shaped strip ribs and the bottom plate can slide along the upper end surface of the horizontal plate.

[0012] Optionally, the arc surface is a circular arc with the outer upper edge of the positioning groove as the center of the circle, and the vertical plate can be turned outwards with the outer upper edge of the positioning groove as the turning point.

[0013] Optionally, the turning point of the outer upper edge of the positioning groove is higher than the inner upper end face of the top plate.

[0014] Optionally, a reinforcing rib plate is arranged on the vertical plate to enhance the structural strength of the vertical plate.

[0015] Optionally, the fixing assembly includes a diagonal brace corresponding to the vertical plate. One end of the diagonal brace is tightly abutted against the vertical plate through a back brace, and the other end supports the ground. It also includes a tie rod. The front end of the tie rod penetrates through the vertical plate and is connected to the precast steel mesh of the precast concrete wall, and the tail end of the tie rod is connected to the back brace.

[0016] Optionally, the formwork assembly is made of aluminum alloy material to reduce the overall weight of the formwork assembly, improve the construction quality, extend the service life, and reduce the maintenance cost.

[0017] The present invention also provides a construction method based on the aforementioned combined housing building formwork system, which includes the following steps:

[0018] Installation step: First, place the wedge-shaped strip rib on the cross plate of the bottom corner baffle, so that the lower end face and the side end face of the wedge-shaped strip rib are tightly attached to the cross plate and the vertical plate of the bottom corner baffle respectively. Fix the bottom corner baffle to the lower end of the vertical plate through the side screw, so that the wedge-shaped strip rib is accommodated in the accommodation space formed by the enclosure of the inclined plate, the bottom plate, the vertical plate and the cross plate of the bottom corner baffle. Use the vertical screw to penetrate through the bottom plate and the threaded hole of the wedge-shaped strip rib and tightly abut against the rubber bottom stop to complete the preliminary assembly of the formwork assembly. Place the preliminarily assembled formwork assembly corresponding to the precast concrete wall at the construction position, and then use the fixing assembly to install and fix the formwork assembly;

[0019] Form removal step: First, remove the side screw, and then rotate the bolt head at the top of the vertical screw. The rotation of the vertical screw drives the wedge-shaped strip rib to move upward to lift the inclined plate. The inclined plate is stressed to drive the vertical plate to turn outward, and finally the vertical plate is separated from the concrete wall.

[0020] In one embodiment, after the preliminary assembly of the formwork assembly in the installation step, the following steps are further included: Clamp and fix the top plate of the vertical plate and the inner corner plate through the concave-convex assembly structure, place the pressure strip on the rubber bottom stop of the bottom corner baffle, and adjust the vertical screw to press the pressure strip to complete the assembly of the formwork assembly.

[0021] In one embodiment, when the vertical plate turns outward in the form removal step, the following steps are further included: The lower end faces of the wedge-shaped strip rib and the bottom plate are in sliding fit with the upper end face of the cross plate through an arc surface. Under the supporting and guiding action of the arc surface, the vertical plate rotates outward with the outer upper edge of the positioning groove of the top plate as the turning point, so that the vertical plate smoothly separates from the concrete wall along a predetermined movement track.

[0022] The beneficial effects of the present invention are:

[0023] The present invention sets a demoulding structure by the vertical plate corresponding to the template assembly, and uses the oblique structure of the wedge-shaped strip to lift the vertical plate during demoulding, so that it is gradually separated from the concrete wall, thereby realizing the stable removal of the template assembly. Compared with the traditional demoulding operation method, the present invention does not need to use auxiliary tools such as demoulding hammers and demoulding rods, will not damage the template assembly, is convenient and quick to operate, reduces the labor intensity of construction personnel, and improves the operation efficiency. During the demoulding process, the concrete wall is not used as a fulcrum for prying the template, which eliminates the problem of the demoulding rod damaging the concrete wall and ensures the quality of the wall surface. The template assembly is gradually separated from the concrete wall by rotating the vertical screw to drive the wedge-shaped strip to lift the vertical plate, so that the process of the template assembly leaving the concrete wall is stable and controllable, which overcomes the problem that the demoulding force is uncontrollable during the traditional demoulding operation, the template is prone to fall randomly, threatens the safety of the operation, and damages the concrete wall and the template, thereby improving the recycling rate of the template assembly and reducing the recycling cost. The use of high-strength alloy enhances the durability and stability of the building template system.

[0024] In the present invention, the vertical screw is used to tighten the rubber bottom stop when the mold is installed, and can be used to lift the wedge-shaped strip when the mold is removed, so that the vertical screw has a dual role, the number of parts configured in the template assembly is reduced, and the structure of the template assembly is simplified.

[0025] The lower end surface of the wedge-shaped strip, the upper end surface of the horizontal plate and the lower end surface of the bottom plate are correspondingly provided with arc surfaces with the same curvature. When demolding, the lower end surfaces of the wedge-shaped strip and the bottom plate will slide and cooperate with the upper end surface of the horizontal plate. Under the support and guidance of the arc surface of the horizontal plate, the vertical plate will smoothly detach from the concrete wall with a predetermined moving trajectory, ensuring that the demolding process is stable and reliable. The arc surface is an arc with the outer upper edge of the positioning groove as the center. When demolding, the vertical plate will flip outward with the outer upper edge of the positioning groove as the turning point. Under the constraint of the positioning convex ridge, the inner side of the vertical plate will not hit the concrete wall. The outer upper edge of the positioning groove is higher than the inner upper end surface of the top plate, ensuring that when the vertical plate flips, the inner turning trajectory of the top plate does not interfere with the concrete wall, avoiding scratches on the concrete wall and ensuring the quality of the concrete wall.

[0042] As Figures 1-8 shown, a combined building formwork system for a building includes a formwork component 100 provided corresponding to a precast concrete wall 400 for shaping and pouring the concrete wall 400, and a fixing component 200 is provided corresponding to the formwork component 100 for supporting and fixing the formwork component 100. The formwork component 100 includes a vertical plate 110 provided corresponding to the vertical surface of the precast concrete wall 400. The bottom of the vertical plate 110 is connected by a side screw 111 to a bottom corner baffle 150 provided corresponding to the bottom corner of the precast concrete wall 400. The top of the vertical plate 110 is provided with an inside corner plate 160 corresponding to the inside corner of the precast concrete wall 400. During use, the formwork component 100 is erected vertically corresponding to the precast concrete wall 400. After being supported and reinforced by the fixing component 200, the concrete pouring operation can be carried out. After the concrete wall 400 is solidified and meets the process requirements, the formwork component 100 can be removed and recycled.

[0043] In order to facilitate the dismantling operation of the formwork assembly 100, the formwork assembly 100 also includes a demolding structure 300, and the demolding structure 300 includes a wedge-shaped strip 310 arranged corresponding to the vertical plate 110. When demolding, the oblique angle structure of the wedge-shaped strip 310 is used to lift the vertical plate 110 so that it is gradually separated from the concrete wall 400, thereby realizing the overall demolition of the formwork assembly 100. Specifically, an inclined plate 120 is provided at the bottom of the vertical plate 110, and the bottom end of the inclined plate 120 is connected to the bottom plate 130. The bottom corner baffle 150 includes a vertical plate 151 and a horizontal plate 152. The wedge-shaped strip 310 is accommodated in the accommodating space formed by the inclined plate 120, the vertical plate 151, the horizontal plate 152 and the bottom plate 130. The upper end of the wedge-shaped strip 310 is provided with a first bevel 311, and the first bevel 311 is set between the inclined plate 120 and the vertical plate 151 of the bottom corner baffle 150. The inclination of the inclined plate 120 corresponds to the first bevel 311 of the wedge-shaped strip 310, so that the two sides of the first bevel 311 of the wedge-shaped strip 310 are respectively attached to the inclined plate 120 and the vertical plate 151 of the bottom corner baffle 150. A U-shaped through hole 131 is provided on the bottom plate 130, and a threaded hole 313 is coaxially provided at the tail end of the wedge-shaped strip 310 corresponding to the U-shaped through hole 131. The vertical screw 180 penetrates the threaded hole 313 of the wedge-shaped strip 310 and passes through the U-shaped through hole 131 of the bottom plate 130. The lower end of the vertical screw 180 is a planar structure, and a moving space 170 for the wedge-shaped strip 310 to be lifted upward is reserved in the accommodating space formed by the inclined plate 120, the vertical plate 151, the horizontal plate 152 and the bottom plate 130.

[0044] Formwork removal steps: first remove the side screws, then rotate the bolt head on the top of the vertical screw 180. The rotation of the vertical screw drives the wedge-shaped strips 310 to move upward to lift the inclined plate 120. The inclined plate is forced to drive the vertical plate 110 to flip outward, and finally the vertical plate is separated from the concrete wall 400.

[0045] During operation in this embodiment, there is no need to use auxiliary tools such as demolding hammers and demolding rods, and the formwork assembly 100 will not be damaged. The operation is convenient and quick, which reduces the labor intensity of construction workers and improves work efficiency. During the demolding process, the concrete wall 400 is not used as a fulcrum for prying the formwork, which eliminates the problem of the demolding rod damaging the concrete wall 400 and ensures the quality of the wall surface. By rotating the vertical screw 180 to drive the wedge-shaped strip 310 to lift the vertical plate 110, the formwork assembly 100 is gradually separated from the concrete wall 400. The process of the formwork assembly 100 separating from the concrete wall 400 is stable and controllable, which improves the problem that the demolding force is uncontrollable during the traditional demolding operation, the formwork is prone to fall randomly, threatening the safety of the operation, and damaging the concrete wall 400 and the formwork.

[0046] As a preferred embodiment, Figure 6As shown, a second bevel angle 312 is provided at the tail end of the wedge-shaped strip rib 310, and the inclined surface of the second bevel angle 312 is parallel to the inclined plate 120. The bottom plate 130 is provided with a wedge-shaped surface corresponding to the second bevel angle 312, and the slope of the wedge-shaped surface is equal to the slope of the inclined plate 120. During form removal, the jacking force of the wedge-shaped strip rib 310 will act on the wedge-shaped surface of the bottom plate 130 synchronously through the second bevel angle 312, jointly moving the vertical plate 110 away from the concrete wall 400, increasing the acting area of the jacking force, and further ensuring the stable and controllable form removal force.

[0047] Preferably, as Figure 2 、 3 、6 shows, a rubber bottom stop 153 is provided at the lower end of the bottom corner baffle 150 to improve the sealing performance of the bottom corner baffle 150 and prevent slurry leakage during the pouring of the concrete wall 400. The bottom end of the vertical screw 180 penetrates through the transverse plate 152 of the bottom corner baffle 150, and the bottom end of the vertical screw presses tightly against the rubber bottom stop 153. During installation, rotate the vertical screw 180 to make the vertical screw descend and press tightly against the rubber bottom stop 153 to realize the pressing and fixing of the rubber bottom stop 153; during form removal, rotate the vertical screw 180 in the reverse direction to drive the wedge-shaped strip rib 310 to push the vertical plate 110 away from the concrete wall 400. Further, a pressing strip 154 is provided between the rubber bottom stop 153 and the bottom end of the vertical screw to ensure that the pressing force in the length direction of the rubber bottom stop 153 tends to be consistent, further improving the sealing performance and installation reliability of the rubber bottom stop 153. This embodiment enables the vertical screw 180 to have the dual functions of pressing the rubber bottom stop 153 and jacking the wedge-shaped strip rib 310, reducing the number of parts configured and simplifying the structure of the formwork assembly 100.

[0048] Preferably, as Figure 4 、 5 、7 shows, a top plate 140 is provided at the top end of the vertical plate 110, and a concave-convex assembly structure is provided on the outer side of the top plate 140 corresponding to the lower end surface of the internal corner plate 160 for the positioning and assembly of the vertical plate 110 and the internal corner plate 160. The concave-convex assembly structure includes a positioning groove 141 opened on the top plate 140, and a positioning rib 161 is provided on the lower end surface of the internal corner plate 160 corresponding to the positioning groove 141. During installation, the positioning rib 161 is clamped in the positioning groove 141 to realize the positioning and assembly of the vertical plate 110 and the internal corner plate 160, ensuring the assembly accuracy and improving the structural stability at the same time. The cross sections of the positioning groove 141 and the positioning rib 161 are preferably trapezoidal structures with the upper base wider than the lower base to facilitate the rapid separation of the vertical plate 110 and the internal corner plate 160 during form removal.

[0049] Preferably, as Figure 6As shown, the lower end surface of the wedge-shaped strip 310, the upper end surface of the cross plate 152 and the lower end surface of the bottom plate 130 are correspondingly provided with arc surfaces 190 with the same curvature. When demolding, the lower end surfaces of the wedge-shaped strip 310 and the bottom plate 130 will slide with the upper end surface of the cross plate 152. Under the support and guidance of the arc surface 190 of the cross plate 152, the vertical plate 110 will smoothly separate from the concrete wall 400 along a predetermined moving trajectory, ensuring that the demolding process is stable and reliable.

[0050] Preferably, if Figures 5-7 As shown, the arc surface 190 is an arc with the outer upper edge of the positioning groove 141 as the center. When the mold is removed, the vertical plate 110 will turn outward with the outer upper edge of the positioning groove 141 as the turning point 191. Under the restraining effect of the positioning convex ridge 161, the inner side of the vertical plate 110 will not hit the concrete wall 400, thereby ensuring the quality of the concrete wall 400. The turning point 191 of the outer upper edge of the positioning groove 141 is higher than the inner upper end surface of the top plate 140, so as to ensure that when the vertical plate 110 turns over, the inner turning track of the top plate 140 does not interfere with the concrete wall 400, thereby avoiding scratching the concrete wall 400.

[0051] Preferably, a reinforcing rib plate 112 is provided on the vertical plate 110 to strengthen the structural strength of the vertical plate 110 and avoid bending deformation caused by the deflection force of concrete during the pouring process, thereby affecting the pouring quality of the concrete wall 400 .

[0052] Preferably, if Figure 1 As shown, the fixing assembly 200 includes a diagonal brace 210 corresponding to the vertical plate 110, one end of the diagonal brace 210 is pressed against the vertical plate 110 through a back rib 220, and the other end supports the ground; and also includes a tie rod 230, the front end of the tie rod 230 passes through the vertical plate 110 and is connected to the prefabricated steel mesh of the precast concrete wall 400, and the rear end of the tie rod 230 is connected to the back rib 220. The setting of the fixing assembly 200 ensures that the template assembly 100 is installed firmly and reliably, and is easy to disassemble and recycle.

[0053] Preferably, the template assembly 100 is made of aluminum alloy, which has the excellent characteristics of light weight, high strength and strong weather resistance, and can significantly reduce the overall weight of the template assembly 100, improve construction quality, extend service life and reduce maintenance costs.

[0054] At the same time, the present invention also provides a construction method based on the aforementioned modular house building template system, comprising the following steps:

[0055] Installation steps: First, place the wedge-shaped strip rib 310 on the cross plate 152 of the bottom corner baffle 150, making the lower end face and side end face of the wedge-shaped strip rib 310 closely fit with the cross plate 152 and the vertical plate 110 of the bottom corner baffle 150 respectively. Fix the bottom corner baffle 150 to the lower end of the vertical plate 110 through the side screw 111, so that the wedge-shaped strip rib 310 is accommodated in the accommodation space formed by the enclosure of the inclined plate 120, the bottom plate 130, and the vertical plate 151 and cross plate 152 of the bottom corner baffle 150. Pass the vertical screw 180 through the U-shaped through hole 131 of the bottom plate 130 and thread it onto the threaded hole 313 of the wedge-shaped strip rib 310 to complete the preliminary assembly of the formwork assembly 100. Place the preliminarily assembled formwork assembly 100 on the construction site corresponding to the pre-cast concrete wall 400, and then use the fixing assembly 200 to install and fix the formwork assembly 100.

[0056] Form removal steps: First, remove the side screw, and then rotate the bolt head at the top of the vertical screw 180. The rotation of the vertical screw drives the wedge-shaped strip rib 310 to move upward to lift the inclined plate 120. The inclined plate is stressed to drive the vertical plate 110 to turn outward, and finally the vertical plate is separated from the concrete wall 400.

[0057] Preferably, after the preliminary assembly of the formwork assembly 100 in the installation steps, the following steps are further included: Clamp the top plate 140 of the vertical plate 110 and the internal corner plate 160 through the concave-convex assembly structure, place the pressing strip 154 on the rubber bottom stop 153 of the bottom corner baffle 150, and adjust the vertical screw 180 to press the pressing strip 154 to complete the assembly of the formwork assembly 100.

[0058] Preferably, when the vertical plate 110 turns outward in the form removal steps, the following steps are further included: The lower end faces of the wedge-shaped strip rib 310 and the bottom plate 130 are in sliding fit with the upper end face of the cross plate 152 through the arc surface 190. Under the support and guiding action of the arc surface 190, the vertical plate 110 rotates outward with the outer upper edge of the positioning groove 141 of the top plate 140 as the turning point 191, so that the vertical plate 110 is separated from the concrete wall 400 along a predetermined movement track smoothly.

[0059] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0060] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of this application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application should be subject to the appended claims.
