Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when pouring the anti-cracking wall, the reinforcement cage must be fixed at the place where the anti-cracking wall is to be poured, and then the thin plates in the above-mentioned scheme are fixed at both ends of the reinforcement cage, and the thin plates are arranged in sequence After fixing, a pouring cavity can be formed between the thin plates at both ends of the reinforcement cage, and then the concrete is poured in the pouring cavity. When the concrete is solidified, the thin plates are completely removed
The shape of the two ends of the formed concrete wall will be the same as the inner end of the thin plate, so the flatness and orderliness of the thin plate determine the flatness of the two ends of the concrete wall. In the above scheme, the thin plates at both ends of the concrete wall cannot guarantee mutual Parallel, thus affecting the flatness of the concrete wall

Embodiment 1

[0045] see figure 1 , a formwork used to manufacture anti-crack concrete walls, including a reinforcement cage 1 arranged on the ground and a thin plate 2 and a base plate 28 arranged on both sides of the reinforcement cage 1, guide assemblies 3 are arranged on both sides of the reinforcement cage 1, guide The assembly 3 includes positioning bases 4 arranged in parallel on both sides of the lower end of the reinforcement cage 1, a connecting seat 5 arranged at one end of the two positioning bases 4, and a socket for inserting the reinforcement cage 1 is formed between the two positioning bases 4. Connect groove 30.

[0046] see image 3 and Figure 5 , the positioning base 4 includes a base 6 at the lower end and a ruler seat 7 at the upper end, the contact surface of the base 6 and the ruler seat 7 is a horizontal plane, and the lower end of the base 6 is connected with a plurality of universal pulleys 8 by bolts, so that the universal pulley 8 Under action, the whole guid...

Embodiment 2

[0055] A construction method for manufacturing formwork of anti-crack concrete wall

[0056] Including step 1, the connecting seat 5 and the positioning base 4 at both ends thereof are pushed toward one end of the reinforcement cage 1, so that the reinforcement cage 1 is inserted into the insertion slot 30, and the ruler base 7 is driven to rise by driving the cylinder 11;

[0057] Step 2, insert the slide bar 13 at one end of the thin plate 2 into the chute 12, so that one end of the thin plate 2 abuts against the inner end of the positioning base 4, and at the same time make the lower end of the thin plate 2 close to the bottom surface;

[0058] Step 3, measure the distance between the two ends of the reinforcement cage 1 and the inner end surface of the thin plate 2 through the distance measuring component 20, adjust the positions of the positioning base 4 at both ends through the measured distance, so that the distance between the two thin plates 2 and the two ends of the r...

Abstract

The invention relates to a formwork for manufacturing crack-resistant concrete walls and a construction method thereof. The two sides of the steel cage are provided with guide assemblies for the insertion and sliding of the thin plates. The guide assemblies include positioning bases arranged in parallel on both sides of the lower end of the steel cage, and two sets of positioning bases at one end of the two sets of positioning bases. A connection seat, an insertion groove for the insertion of the steel cage is formed between the two sets of positioning bases, a sliding bar is provided on the outside of the thin plate, and a sliding bar is provided on the upper end of the positioning base for the sliding insertion of the sliding bar. The lower end of the thin plate abuts against the ground, and the outer end of the thin plate abuts against the inner end of the positioning base. The invention has the characteristics of ensuring that the two ends of the concrete are parallel to each other, and the thickness between the two ends of the concrete and the reinforcement cage in the concrete is the same.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a formwork for manufacturing a crack-resistant concrete wall and a construction method thereof. Background technique [0002] At present, concrete walls (beams and columns), lightweight block walls and clay hollow brick walls basically constitute the load-bearing, enclosure and partition space system of the building. Concrete is a heterogeneous brittle material formed by mixing sand and gravel aggregates, cement, water and other external materials. Due to a series of problems such as concrete construction and its own deformation and constraints, there are many micro-pores, air pockets and micro-cracks in the hardened concrete. When the large-volume concrete is hardened, a large amount of heat of hydration will be released, resulting in excessive internal temperature of the concrete. High, often with many cracks. Micro-cracks do not harm the load-bearing, anti-seep...
